Purpose: To examine the clinical efficacy of a chlorhexidine gargle combined with recombinant bovine basic fibroblast growth factor (rb-bFGF) gel in the treatment of recurrent oral ulcers and its effects on inflammatory factors, immune function, and recurrence rate. Materials and Methods: Ninety-six patients with recurrent oral ulcers were randomly assigned to two groups: experimental (treatment with chlorhexidine gargle plus rb-bFGF gel) and control (treatment with chlorhexidine gargle alone) (n = 48 cases). The therapeutic efficacy, clinical improvement of symptoms, and recurrence rate within 3 months were compared between the two groups. Serum inflammatory factor and immune factor levels of patients in the two groups were measured before and after treatment. Results: A statistically significantly higher total effective rate was found in patients of the experimental group (95.83%) versus the control group (81.25%) (p < 0.05). The time to onset of pain relief was shortened, the duration of pain relief was prolonged, and VAS scores for pain level were lower in the experimental than the control group (p < 0.05). Among patients in the experimental group, the number of oral ulcers and ulcer area decreased, and faster onset of pain relief and time until normal eating improved in comparison to the control group (p < 0.05). Reduced levels of IL-2, IL-6, IL-8, and TNF-α were observed in the experimental vs the control group (p < 0.05). Elevated levels of CD3+, CD4+, and NKT and reduced levels of CD8+ were found in the experimental group compared to the control group (p < 0.05). The ulcer recurrence rate of patients in the experimental group (8.33%) was notably lower in comparison to the control group (29.17%). Conclusion: Chlorhexidine gargle plus rb-bFGF gel can improve the clinical outcome of patients with recurrent oral ulcers. It can reduce the levels of inflammatory factors, improve immune function, and reduce the recurrence rate. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Poor sleep is associated with increased inflammation, thereby increasing the risk of chronic diseases and mortality. However, the effects of behavioral sleep interventions on the upstream inflammatory system are unknown among family care partners (CP). The present study explored the role of a behavioral sleep intervention program on inflammatory gene expression. METHODS: This was part of a randomized controlled trial of a sleep intervention for dementia care dyads with sleep problems. Thirty dyads were randomized to sleep intervention or control groups. Sleep outcomes for CP were assessed with 1 week of actigraphy and sleep diary, and the Pittsburgh Sleep Quality Index. Other information included CP demographics, body mass index, and intensity of caregiving tasks. All outcomes were collected at baseline, post-treatment, and 3-month follow-up. RESULTS: Neither group showed any significant differential changes in gene expression from baseline to post-treatment or 3-month follow-up. A decrease in inflammatory gene expression was significantly associated with more nights of good sleep (i.e. nights without trouble falling or staying asleep at night). This finding remained significant after controlling for group (intervention/control), timepoint (baseline, post-treatment, and 3-month follow-up), and CP characteristics (e.g. age and ethnicity). CONCLUSIONS: Although better sleep was associated with decreased inflammatory gene expression, this study did not demonstrate any benefits of a behavioral sleep intervention over control, most likely due to a small sample. Studies with larger sample sizes are needed to test the specific aspects of disturbed sleep that relate to inflammatory biology among CP of persons living with dementia.

IntroductionNon-Hodgkin's lymphoma (NHL) encompasses a diverse group of lymphoma subtypes with a wide range in disease course. Previous studies show that hypogammaglobulinemia in treatment-naïve patients is associated with poorer survival in high grade B-cell non-Hodgkin's lymphomas, though it is not known how this applies across all B-cell lymphoid malignancies.MethodsWe conducted a retrospective study of immunoglobulin levels and clinical outcomes including survival, hospitalization, and infection rates in patients diagnosed with B-cell non-Hodgkin lymphomas of all grades at our institution.ResultsTwo-hundred twenty-three adults (aged = 18 years) with available pre-treatment IgG levels were selected, with hypogammaglobulinemia defined as IgG< 500 mg/mL. For this analysis, we grouped DLBCL (n=90), Primary CNS (n=5), and Burkitt lymphoma (n=1) together as high-grade, while CLL (n=52), mantle cell (n=20), marginal zone (n=25), follicular (n=21), and Waldenstrom macroglobulinemia (n=5) were low-grade. The incidence of hypogammaglobulinemia in our cohort of both high and low-grade lymphoma patients was 13.5% (n=30). Across all NHL subtypes, individuals with baseline IgG< 500 mg/dL showed an increased rate of hospitalization (4.453, CI: 1.955-10.54, p= 0.0005) and higher mortality (3.325, CI: 1.258, 8.491, p= 0.013), yet no association in number of infections when compared with those with IgG=500 mg/dL. There was a higher hospitalization rate (3.237, CI: 1.77-6.051, p=0.0017) in those with high-grade lymphoma with hypogammaglobulinemia when compared with low-grade. There was no statistically significant difference in individuals who were alive after three years in those with baseline IgG

This study aimed to investigate the effect of hetrombopag combined with conventional treatment on immune function in patients with severe aplastic anemia (SAA). Patients were categorized into the control group (n = 50, receiving conventional treatment only) and experimental group (n = 50, receiving hetrombopag combined with conventional treatment). Before treatment and at weeks 18, 24, and 52 after treatment, the two groups were compared in routine blood test indicators, natural killer (NK) cell activity, and peripheral blood inflammatory factor levels. The overall remission rate and incidence of adverse events were also compared between the two groups. Outpatient or telephone follow-up was performed before treatment and at weeks 18, 24, and 52 after treatment to observe patients' immune function, treatment outcome, quality of life, and adverse events. Hemoglobin (Hb), and platelet count (PLT) (P < 0.05), and a rise in NK cell activity (P < 0.05). Interleukin (IL-10) levels were significantly higher, while IL-6 levels were significantly lower in the experimental group compared to the control group (P < 0.05). After receiving the treatment, all scores of SF-36 domains in both groups were higher than before treatment, particularly with higher scores in the experimental group (P < 0.05). Hetrombopag combined with conventional treatment improved the immune function and hematopoiesis of patients with SAA. [ABSTRACT FROM AUTHOR]

Objective: To explore the expression characteristics and clinical value of immune function indicators in patients with human immunodeficiency virus (HIV) infection. Methods: In this retrospective study, clinical data of 196 patients with HIV infection (observation group) and 196 health examinees (control group) admitted to our hospital from November 2021 to March 2023 were retrospectively analyzed. Patients in the observation group were further classified based on the staging as acute phase (n=53), asymptomatic phase (n=65), and acquired immunodeficiency (AIDS) phase (n=78). Levels of immune function indicators in the observation group and the control group were compared, and the correlation between immune function index levels and disease staging was analyzed. Results: Levels of CD3+, CD4+, CD4+/CD8+, B cells, and NK cells were lower in the observation group (P<0.05), were significantly lower in asymptomatic patients compared with patients in the acute phase (P<0.05), and were significantly lower in patients with AIDS than those in asymptomatic patients (P<0.05). The results for CD8+ were in contrast to the above(P<0.05). Spearman analysis confirmed that levels of CD3+, CD4+, CD4+/CD8+, B cells and NK cells significantly negatively correlated, and levels of CD8+ significantly positively correlated with the stages of HIV (P<0.05). Conclusions: The immune function indicators of patients with HIV infection are markedly abnormal, which is mainly manifested by the decreased levels of CD3+, CD4+, CD4+/CD8+, B cells and NK cells, and the increased levels of CD8+. The profile of the immune function indicators correlates with the progressive severity of the disease. [ABSTRACT FROM AUTHOR]

Complications from general anesthesia, including pneumonia and decreased wound healing, are influenced by changes in immune cell function secondary to sedatives and anesthetics. It was hypothesized that immune cell function would be depressed in the early postanesthetic period. The objective was to investigate airway immune cell function before and after a general anesthetic episode in an equine in vivo model using ex vivo cell stimulations with lipopolysaccharide (LPS) for assessment of immune function. Prospective experimental study. Six healthy, adult, institution-owned horses. Each horse underwent a bronchoalveolar lavage (BAL) 3 days before and immediately after a 2 hour general anesthetic. The BAL fluid was examined for cytology, total nucleated cell count and isolation of immune cells. Airway immune cells were treated with LPS or media (control) for 6 hours and supernatant was analyzed via a commercially available immunoassay for cytokines [tumor necrosis factor alpha (TNFα), interleukin (IL)-1β, IL-6, interferon gamma (IFNγ) and CXC motif chemokine ligand 8 (CXCL8)]. Data were compared using t -tests and Mann–Whitney tests. Before anesthesia (baseline), LPS stimulation induced a significant increase in all cytokines of interest, except CXCL8, versus control samples. Unstimulated cells, after an anesthetic episode, had a significant 1.8-fold increase in IL-1β (p = 0.029), and a significant decrease in IL-6 and TNFα (p = 0.028 and 0.033, respectively) versus baseline. Following anesthesia, stimulated cells had a significant decrease in IL-6 and TNFα (p = 0.037 and 0.042, respectively) versus baseline. This study supports the use of an equine in vivo model to assess airway immune cell function in relation to general anesthetic use. [ABSTRACT FROM AUTHOR]

The regulatory role of estrogen receptor beta (ERβ) and the JNK signaling pathway in the effect of high-dose boron on rat splenic lymphocytes has been examined by measuring proliferation, apoptosis, and immune function. The results showed that, compared with the control group, the addition of high-dose boron (40 mmol/L) reduced the proportion of CD3+, CD4+, and CD8+ T lymphocytes, the concentrations of IgG, IL-2, IFN-γ, and IL-4, the proliferation rate of splenic lymphocytes, and the expression levels of PCNA and Bcl-2 mRNA (P < 0.01 or P < 0.05), and increased the apoptosis rate of splenic lymphocytes, caspase-3, and BAX mRNA expression levels (P < 0.01 or P < 0.05). After specific blocking of ERβ, the addition of high-dose boron could not reduce the proportion of CD8+ T lymphocytes, the concentrations of IgG and cytokines IL-2, IFN-γ, and IL-4, the lymphocyte proliferation rate, or PCNA mRNA expression levels, nor could it increase BAX mRNA expression levels. After specific blocking of JNK, the addition of high-dose boron could not increase BAX mRNA expression levels. However, after specific blocking of ERβ and JNK, the addition of high-dose boron could neither reduce the proportion of CD4+ and CD8+ T lymphocytes, the concentrations of IgG and IL-2 (P > 0.05), nor increase caspase-3 and BAX mRNA expression levels (P < 0.01). The results suggest that the ERβ-mediated JNK signaling pathway participates in regulating the effects of high-dose boron on the expression of genes related to the proliferation and apoptosis of rat splenic lymphocytes.

This prospective interventional study investigated the impact of individualized nutritional interventions on immune function and infection rates in burn patients. This study enrolled 120 burn patients between December 2022 and January 2024. The nutritional interventions focused on protein supplementation, micronutrient replenishment, and inclusion of anti-inflammatory nutrients, specifically omega-3 fatty acids and vitamin C. The nutrients were administered through oral, enteral, and parenteral routes based on dietary preferences and the medical condition of individuals. Protein was prioritized because of its role in leukocyte production; zinc and vitamin C were supplemented to optimize immune function; and omega-3 fatty acids were included to mitigate inflammation and enhance wound healing. The study assessed outcomes through changes in leukocyte and lymphocyte counts, cytokine levels, infection rates, wound healing rates, and the length of hospital stays. Results indicated significant improvements in immune markers and reduced infection rates post-intervention (P < 0.05). Leukocyte count increased significantly, cytokine levels decreased, and the infection rate reduced from 30% to 14.2% (P < 0.05). These outcomes highlighted the efficacy of targeted nutritional interventions in supporting immune health and reducing infections in burn patients. The findings advocated for integrating comprehensive nutritional strategies in managing burn injuries to improve clinical outcomes. [ABSTRACT FROM AUTHOR]

Objective: Allergic rhinitis (AR) is a growing public health problem worldwide. Respecting the significance of the modified Lund-Kennedy (MLK) score in rhinitis assessment, we delved into its evaluation value on the sublingual immunotherapy (SLIT) efficacy in AR patients. Methods: Totally 100 AR patients were enrolled, with pre- and post-SLIT MLK score, total nasal symptoms score (TNSS), total medication score (TMS), visual analogue scale (VAS), inflammatory cytokines, and immune function-related parameters compared. The correlations of MLK score with TNSS/TMS/VAS, as well as with IL-4/INF-γ/eosinophil (EOS)/percentage/specific immunoglobulin (sIgE)/sIgG were assessed by Spearman correlation analysis. The value of MLK score on assessing SLIT efficacy in AR patients was analyzed. Results: SLIT treatment reduced MLK/TNSS/TMS/VAS scores, abated IL-4 level/EOS percentage/sIgE, and elevated INF-γ/sIgG levels. MLK score was positively correlated with pre- and post-SLIT TNSS score (rpre−treatment = 0.592, rpost−treatment = 0.756), TMS score (rpre−treatment = 0.385, rpost−treatment = 0.718), VAS score (rpre−treatment = 0.369, rpost−treatment = 0.704), IL-4 (rpre−treatment = 0.553, rpost−treatment = 0.639), EOS percentage (rpre−treatment = 0.511, rpost−treatment = 0.632), and sIgE (rpre−treatment = 0.472, rpost−treatment = 0.524), and negatively with INF-γ (rpre−treatment = −0.418, rpost−treatment = −0.578) and sIgG4 (rpre−treatment = −0.460, rpost−treatment = −0.613). The MLK score had an area under curve of 0.846 (77.01% sensitivity, 76.92% specificity, 4 cut-off value) and 0.944 (91.67% sensitivity, 92.11% specificity, 2 cut-off value) for assessing SLIT treatment as effective and markedly effective for the patients, respectively. Conclusion: The MLK score had good evaluation value on the efficacy of SLIT treatment in AR patients. [ABSTRACT FROM AUTHOR]

To analyze the changes of immune function-related indicators with newly diagnosed glioblastoma before and after radiotherapy and their clinical significance. Clinical data of 104 patients were analyzed. The independent samples t-test or chi-square test was used to compare changes in immune function indicators and to ascertain the differences between groups with different doses or volumes. The grading of the lowest lymphocyte count during radiotherapy was compared. The log-rank (Mantel – Cox) test of the Kaplan – Meier method was used to compare the survival rate, and the relationship of radiotherapy-related parameters, with the survival rate was evaluated by using the Spearman correlation coefficient. A Cox regression model was used to determine the relationship between various immune function indicators and prognosis. The percentages of total T lymphocytes and CD4+ T cells, the CD4-to-CD8 subset ratio, and the percentages of B cells and NKT cells showed an overall decreasing trend, whereas the percentages of CD8+ T cells and NK cells displayed an overall increasing trend. The lower CD4+ T cell percentage and CD4/CD8 ratio after radiotherapy were independent risk factors for OS. Short OS was observed in patients with grade 3 or 4 lymphopenia or with low levels of hemoglobin and serum albumin before radiotherapy. The percentage of CD4+ T cells and the CD4/CD8 ratio were higher in patients with the low tumor-irradiated volume and irradiated volume and dose of the OAR, than in patients from the corresponding high indicator group. Different irradiation dose or volume can differentially alter various immune function indicators. [ABSTRACT FROM AUTHOR]

In this study, Lagenaria siceraria (Molina) Standi polysaccharides (LSP) was prepared using the water-alcohol precipitation method to evaluate its effects on growth performance, slaughter performance, cytokines, immune organ indices, cecal short-chain fatty acids (SCFAs), and microbial community structure in broiler chickens when added to the basal diet. Seventy-five broiler chickens were selected and randomly divided into five groups, with 15 chickens per group. All groups were fed a basal diet for 7 days. From 7 days of age, the control group continued to receive the basal diet, while the positive drug group was fed a diet supplemented with Astragalus polysaccharides (APS, 100 g/kg) in addition to the basal diet. The experimental groups were fed diets containing different concentrations of LSP (50, 100, and 200 g/kg) in addition to the basal diet, and the supplementation continued for 42 days. The findings indicated that the incorporation of LSP into the feed significantly enhanced average daily weight gain (ADWG), average daily feed intake (ADFI), feed to gain ratio (F/G), dressing percentage, percentage of breast muscle, percentage of leg muscle, and percentage of abdominal fat while concurrently reducing drip loss rate and cooking loss rate (p < 0.01) in comparison to the control group. Additionally, it significantly augmented the levels of interleukin-4 (IL-4) and interleukin-12 (IL-12) in cytokines, secreted immunoglobulin A (SIgA) and immunoglobulin G (IgG) in immunoglobulins, as well as immune organ indicators (p < 0.05). Furthermore, LSP also modulated the intestinal microbiome composition by increasing the abundance of Bacteroides species and significantly changing concentrations of specific short-chain fatty acids (SCFAs) such as propionic acid, isobutyric acid, acetic acid, and isovaleric acid (p < 0.01). These results suggest that dietary supplementation with LSP can effectively regulate intestinal microbiome composition while promoting short-chain fatty acid production. The alterations in microbial characteristics ultimately contribute to improved intestinal immunity and immune organ development as well as enhanced production performance and immune function in broilers.

Yeast peptides, which are small-molecule active peptides extracted from yeast proteins, are known for their antibacterial, antioxidant, and anti-inflammatory properties. However, the effects of yeast peptide on suckling calves remain unclear. In this study, the effects of yeast peptide supplementation on the growth, diarrhea incidence, and immune function of calves during the suckling period were determined. Thirty newborn calves were randomly divided into two groups: the control group (CON) and the treatment group (AP), which received fresh pasteurized milk supplemented with yeast peptides (5 g/day). The experiment lasted for 49 days (7-56 days of age). The dry matter intake, body weight, diarrhea status, immune function, antioxidant capacity, and anti-inflammatory activity of the calves were analyzed. The AP group had higher dry matter intake, daily weight gain, and feed efficiency than the CON group (P < 0.05). Moreover, the duration and frequency of diarrhea were significantly lower in the AP group than in the CON group (P < 0.05). Furthermore, the immune, antioxidant, and antiinflammatory capabilities of the AP group were significantly higher than those of the CON group (P < 0.05). These findings provide valuable insights for the improvement of early health management during calf rearing. [ABSTRACT FROM AUTHOR]

Simple Summary: Increased reproductive performance in modern high-yielding sows often results in inadequate energy intake. Many recent studies have focused on the improvement of sow energy intake through the addition of different dietary energy source, but there have few studies on dietary energy concentration based on the net energy system. Our results suggest that increasing the dietary energy concentration can increase immunological substances in milk and improve milk quality and body health in primiparous lactating sows. This study aimed to determine the optimal dietary net energy concentration for the reproductive performance, immune function, milk composition, and gut microbiota of primiparous sows during lactation. Forty primiparous lactating sows (Landrace × Yorkshire) with similar body backfat thicknesses were randomly allocated into five treatment groups and fed diets with different dietary net energy concentrations of 10.05 MJ/kg, 10.47 MJ/kg, 10.89 MJ/kg, 11.30 MJ/kg, and 11.72 MJ/kg. The results showed that there were no differences in the performance of piglets, while there was a decrease in the daily feed intake of sows (p = 0.079, linear) as dietary net energy concentration increased. With the increasing dietary net energy concentration, the plasma insulin levels of sows increased (p < 0.01, linear), the plasma glucose levels tended to increase (p = 0.074, linear), and the blood urea nitrogen levels tended to decrease (p = 0.063, linear). Moreover, the plasma total superoxide dismutase activity of sows increased (p < 0.05, quadratic) and the plasma malondialdehyde content of sows decreased (p < 0.05, quadratic) by increasing the dietary net energy concentration. Interestingly, with the increase in dietary net energy concentration, the plasma immunoglobulin M content of sows increased, the milk immunoglobulin M, immunoglobulin G, immunoglobulin A and the percentage of milk fat increased (p < 0.05, linear), and the milk secretory immunoglobulin A content also increased (p < 0.05, linear and quadratic). The milk immunoglobulins and milk fat content of sows fed with net energy concentration of 11.72 MJ/kg were highest. Moreover, there were significant differences in the α-diversity, β-diversity, and relative abundance of gut microbiota in sows fed with different dietary net energy concentrations. At the phylum level, Spirochaetota and Bacteroidota in the gut microbiota of sows were mainly affected by increasing the dietary net energy concentration. Furthermore, the correlation analysis showed that milk immunoglobulin content had a significant negative correlation with the relative abundance of Bacteroidota, and plasma malondialdehyde content also had a significant negative correlation with the relative abundance of Spirochaetota. In summary, these results suggest that increasing the dietary net energy concentration to 11.72 MJ/kg can increase immunological substances in milk, improve milk quality, and alter the composition of gut microbiota in primiparous lactating sows.

Objective: To assess the inflammatory response and side effects of chemotherapy combined with Shenmai injection (SMI) in the treatment of patients with advanced colorectal cancer (CRC). Methods: This retrospective cohort study included the clinical data of 152 patients with advanced CRC admitted to the First Affiliated Hospital of Huzhou University from April 2020 to April 2023. The patients were divided into control group (patients received chemotherapy treatment, n=75) and observation group (patients received chemotherapy combined with SMI, n=77) based on the treatment received. Tumor control rate, levels of immune function indicators before and after treatment, levels of inflammatory factor indicators, and incidence of toxic side effects in two groups were analyzed. Results: Tumor control rate in the observation group (89.61%) was higher than that in the control group (77.33%) (P<0.05). After the treatment, the levels of CD3+, CD4+, CD4+/CD8+in both groups were significantly higher than before the treatment, and significantly higher in the observation group compared to the control group (P<0.05). After the treatment, serum levels of interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-8 (IL-8) in both groups decreased compared to pretreatment levels, and was significantly lower in the observation group (P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (P<0.05). Conclusions: Compared with chemotherapy alone, chemotherapy combined with SMI better alleviates inflammatory response in patients with advanced CRC, enhance immune function, and improve tumor control rate, with a lower incidence of toxic side effects.

Objective: To evaluate the clinical effects of intraperitoneal chemohyperthermia (IPCH) in the treatment of postoperative patients with advanced stage ovarian cancer, and its impacts on tumor markers and immune functions. Methods: This is a retrospective study. One hundred and twenty patients with advanced stage ovarian cancer received in Shanghai 7th People’s Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from May 10, 2022 to June 10, 2023 were selected and randomly divided into control and study groups (n=60 each group). Patients in the control group were administered routine intravenous chemotherapy, the study group underwent IPCH besides routine intravenous chemotherapy based on the control group. Comparatively analyzed the clinical effects, adverse reaction occurrence rates, and variations in relevant observation targets, the tumor marker after and before the treatment. Results: Total efficacy in the study and control groups are proved to be with statistically significant differences. The occurrence of adverse reactions proved that no significant differences is seen between both groups. After the treatment, CEA, CA19-9, and CA125 levels in patients of the study group are apparently lower than those in the control group, showing statistically significant differences; expression levels of CD3+, CD4+ and CD4+/CD8+, in the study group were enormously above those in the control group after the treatment, with statistically significant differences. Conclusions: IPCH has the potential to effectively enhance comprehensively clinical therapeutic effects among postoperative patients with ovarian cancer, significantly improve patients’ immune states, and evidently reduce expression levels of various tumor markers.

To assess the safety and efficacy of fecal microbiota transplantation (FMT) as an adjunctive therapeutic intervention for IgA nephropathy (IgAN). Fifteen patients with IgA nephropathy were recruited based on inclusion and exclusion criteria and underwent FMT using enteric microbial capsules. Clinical indicators, intestinal microbiota and metabolomic profiles, as well as changes in serum immune cells and cytokines, were monitored before and after FMT. No severe adverse reactions were observed in the subjects. After FMT, there was a reduction in the 24-h urinary protein quantification in subjects. The relative abundances of Phocaeicola_vulgatus, Bacteroides_uniformis, Prevotella_copri, Phocaeicola_dorei, Bacteroides_ovatus, Bacteroides_xylanisolvens, Parabacteroides _distasonis, Bifidobacterium_pseudocatenulatum, Bacteroides_sp._HF-162, and Bifidobacterium_longum changed after FMT. In terms of intestinal metabolites, the levels of acylcarnitine18:0 (ACar.18:0), cotinine, N-arachidonoyl-L-serine, phosphatidylcholine (PC. (18:3e/22:6)), serotonin, and fumagillin showed significant changes. Flow cytometry analysis showed the absolute count of plasma B cells decreased in subjects, and this change correlated with alterations in the intestinal microbiota and metabolites. This study preliminarily evaluates the safety and efficacy of FMT in patients with IgAN. No significant adverse reactions were observed, and the administration of FMT alongside ACEI/ARB therapy was effective in reducing urinary protein levels in patients with IgAN, a process that may be associated with B-cell immunity.

As a member of the small G protein superfamily, ras-related nuclear proteins (Ran) mainly function in regulating nucleocytoplasmic transport and microtubule formation. Ran is reported to have an immune function in invertebrate defense against pathogen invasion. This study obtained the full-length sequence of the Ran cDNA (PcRan) of Procambarus clarkii and investigated changes in its expression after pathogenic infection and its role in the clearance of pathogenic bacteria. Phylogenetic tree analysis revealed that PcRan and Ran of other crustaceans belong to one branch and have a close genetic relationship. Multiple sequence alignment analyses revealed that PcRan has a highly conserved G domain and contains all the G1–G5 motifs. PcRan expression was widely distributed in various tissues in P. clarkii, with the highest expression levels being found in the muscle and gills. The levels of PcRan expression in several major immune organs, including hepatopancreas, gills, hemocytes, and intestines, were significantly increased after infection with white spot syndrome virus or Aeromonas veronii. After PcRan overexpression, the bacterial clearance ability and survival rate of P. clarkii infected with A. veronii was significantly higher than that of the control group. This study showed that PcRan is involved in the innate immune process of P. clarkii. The results of this study provide theoretical significance and application value for understanding the immune function of Ran after crayfish pathogen infection, and provide guidance for the prevention and control of crayfish diseases.

Objective: To investigate the impact of giant salamander protein peptide (CGS) and its Maillard reaction product (CGSXyU) on lowering blood glucose and lipid levels in type II diabetic mice and enhancing immunomodulatory functions in immunosuppressed mice, and anti-fatigue effects in normal mice. Methods: Mice were randomly assigned to a blank control group, a model control group, a positive control group (200 mg/kg metformin), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a high-dose sample group (CGS/CGSXyU-H, 200 mg/kg). Following the successful induction of diabetes with 100 mg/kg alloxan, the mice underwent gavage treatment for 3 weeks, after which their fasting blood glucose levels, serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were measured. Mice were randomly assigned to a blank control group, a model control group, a positive control group (50 mg/kg levamisole), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a high-dose sample group (CGS/CGSXyU-H, 200 mg/kg). Following successful modeling with 100 mg/kg cyclophosphamide, the mice underwent gavage for three weeks, during which their body weights were recorded, and changes in organ indices and cytokine levels were assessed. Similarly, mice were randomly divided into a blank control group, a positive control group (200 mg/kg taurine), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a highdose sample group (CGS/CGSXyU-H, 200 mg/kg). They were subjected to gavage for four weeks, after which the mice's weight-bearing swimming time, urea nitrogen levels, creatine kinase activity, serum lactate levels, and antioxidant enzyme activity were measured. Results: The CGS/CGSXyU-L/H treated group of mice exhibited reduced fasting blood glucose concentration, serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C), along with elevated high-density lipoprotein cholesterol (HDL-C) levels. CGSXyU-H significantly enhanced the body weight (P<0.05), organ index, and levels of immune cytokines (IL-6, IL-10, TNF-α, IFN-γ) in immunocompromised mice. The CGS/CGSXyU-L/H treatment group demonstrated increased time in weight-bearing swimming, reduced creatine kinase activity and serum lactate levels, the BUN level in the CGS-H and CGSXyU-L/H groups decreased, while the GSH-Px activity significantly increased in the CGSXyU-H group (P<0.05), the SOD activity in the CGS-H and CGSXyU-L/H groups also increased. Conclusion: The protein peptides from Andrias davidianus and their Maillard reaction products regulate blood glucose and lipid metabolism in type II diabetes mice, bolster immune function in immunocompromised mice, and effectively improve the anti-fatigue capacity in normal mice.

Introduction: This study analyzed and discussed the characteristics of peripheral blood lymphocytes (PBLs) in patients with endometrial carcinoma (EC) to explore the PBLs' clinical application value. Methods: This single-center case‒control study analyzed the clinical data of patients with EC and uterine fibroids who underwent surgery at the First Affiliated Hospital of Chongqing Medical University between October 2018 and October 2023 retrospectively. The Center for Clinical Molecular Medical Detection of our hospital performed PBLs detection using flow cytometry, and recorded the detection results in the electronic medical records system. Between-group and subgroup comparisons of PBLs in patients with EC were analyzed using t-test or Mann–Whitney U test. The effect of surgery on PBLs in patients with EC was assessed using a paired t-test or the Wilcoxon signed rank test. Results: The immune function of patients with EC was significantly lower than that of healthy people (P < 0.05) and those with benign uterine diseases (P < 0.05) and was related to body mass index (BMI), hypertension, diabetes, and blood lipids (P < 0.05). In patients with EC, the PBLs counts decreased significantly after surgery (P < 0.05) and more kinds of lymphocytes were affected in the laparoscopic surgery group than in the open surgery group. Conclusions: With the decrease of PBLs counts, the immune status of patients with EC is impaired. Metabolic syndrome (Mets), including obesity, hypertension, diabetes, and high blood lipids, also affects the immune function of patients with EC. And for EC patients, the effect of laparoscopic surgery is greater than that of open surgery. PBLs has the potential to be one of indicator during the diagnosis and treatment of EC. Trial registration: This study was retrospectively registered by the Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (approval number K2023-578).

The well-set immune barrier plays an important role in promoting body health and improving poultry production performance. It is generally accepted that intestinal flora is involved in stimulating the development of the immune system, which in turn shape a well-set immune barrier for the host. While pathogenic bacteria in the gastrointestinal tract of poultry are proliferating due to the prohibition of feeding antibiotics in the postantibiotic era. This is bound to disturb the intestinal flora and break the immune barrier, and the production performance of poultry will be negatively affected resultantly. Hence, it is of great significance to clarify the interaction between intestinal flora and immune function in poultry to guide poultry healthy and efficient breeding. In the present study, the research progress about the regulation of intestinal flora on the immune function in poultry were arranged, which aimed to provide the theoretical reference for the healthy and efficient breeding of poultry.

Simple Summary: Bacterial enteritis caused by Salmonella enteritidis infection can reduce the growth performance and increase the mortality of broilers. Antibiotics were the mainstay of treatment for intestinal injury caused by Salmonella enteritidis, but the overuse of antibiotics has resulted in severe drug residues and the emergence of antibiotic-resistant bacteria. Chinese herbs contain natural compounds with high safety and medicinal value, making them good substitutes for antibiotics. Compared with use of a single Chinese herb, the rational combination of multiple herbs could produce synergistic effects to enhance therapeutic outcomes. In this study, the specific compound Chinese herbal medicine (CCHM) consisted of Pulsatilla, Coptis chinensis, Fraxini cortex, Cortex phellodendri, Folium isatidis, Raddix paeoniae alba, Schisandra chinensis, and Fructus mume in a ratio of 15:6:6:6:6:6:6:5. Our results showed that CCHM improved the growth performance, intestinal barrier function, immune response, and cecal microflora of broilers infected with Salmonella enteritidis. This study investigated the effects of CCHM in drinking water on broilers infected with Salmonella enteritidis. One-day-old male Cobb 500 broilers (n = 300) were randomly assigned to five groups: a control (NC) group, a Salmonella enteritidis challenge (SE) group, an antibiotic (AB) group, a low dose of CCHM (CL) group, and a high dose of CCHM (CH) group. Each group had six replicate cages with ten broilers per cage. The broilers in the NC and SE groups were given normal drinking water. From days 12 to 18, the AB group received water treated with ciprofloxacin lactate injection (1 mL/L), while the CL and CH groups received water containing CCHM at doses of 5 mL/L and 10 mL/L, respectively. Broilers in all groups except the NC group were orally given Salmonella enteritidis daily from days 9 to 11. The experimental period was 28 days. The results showed that, compared with the SE group, the CL and CH groups showed improved growth performance; increased immune organ indices, expressions of ileal occludin and ZO-1 proteins, jejunal and ileal villus heights (except at day 19), and cecal Lactobacillus counts on days 19 and 28 (p < 0.05); and decreased jejunal and ileal lesion scores, ileal interleukin 1β (IL-1β) (except at day 19), interferon-γ (IFN-γ), interleukin 6 (IL-6) (except at day 19), secretory immunoglobulin A (slgA) and tumor necrosis factor α (TNF-α) (except at day 19) levels, serum D-lactic acid and diamine oxidase (DAO) (except at day 19) contents, jejunal and ileal crypt depths (except at day 19), and cecal Salmonella and Escherichia coli counts on days 19 and 28 (p < 0.05). On day 28, except for the levels of ileal interleukin 10 (IL-10), TNF-α, slgA, and serum D-lactic acid content, there were no differences among the NC, AB, and CL groups (p > 0.05). In conclusion, drinking water supplemented with CCHM alleviated the intestinal damage caused by Salmonella enteritidis infection and improved growth performance and cecal microbiota in broilers. The optimal addition rate of CCHM was 5 mL/L. [ABSTRACT FROM AUTHOR]

Background: The microbiota and metabolites in the gastrointestinal tracts of female animals at different reproductive periods are very important to the growth, development, and health of themselves and their offspring. However, the changes in the gastrointestinal microbiota and metabolites throughout reproductive period of different sheep breeds and their effects on the growth and development of offspring lambs are still unclear. Hence, this study presents an assessment of the reproductive hormone levels, immune levels, rumen microbiota, and metabolites in Hu sheep and Suffolk ewes at different reproductive periods and their effects on the growth and development of offspring lambs. Results: Hu sheep and Suffolk during non-pregnancy, pregnancy, and lactation were used as the research objects to determine reproductive and immune indexes of ewes at different periods, analyze rumen microbiome and metabolome, and track the growth performance and development of offspring lambs. The results showed that the reproductive hormone and immune levels of Hu sheep and Suffolk underwent adaptive changes across different reproductive periods. Compared with non-pregnancy, the microbial energy metabolism and lipid metabolism function decreased during Hu sheep pregnancy, and energy metabolism function decreased during lactation. In Suffolk, energy metabolism, glycan biosynthesis, and metabolism function were enhanced during pregnancy, and the metabolism of cofactors and vitamins was enhanced during lactation. Prevotella increased in Suffolk during pregnancy and lactation (P < 0.05) and was positively correlated with the birth weight and body size of the lambs (P < 0.05). Moreover, the abundances of Butyrivibrio and Rikenellaceae_RC9_gut_group during pregnancy were positively correlated with the intestinal immunity of the offspring lambs (P < 0.05), thereby regulating the intestinal immunity level of the lambs. Metabolomic analysis revealed that the protein digestion, absorption, and amino acid metabolism of Hu sheep were enhanced during pregnancy, which provided amino acids for the growth and development of pregnant ewes and fetuses and was significantly correlated with the birth weight, body size, and intestinal immunity of lambs (P < 0.05). Simultaneously, there was an increase in acetate and propionate during the pregnancy and lactation period of both Hu sheep and Suffolk, providing energy for ewes during reproductive period. Moreover, the microbiota during the lactation period was significantly correlated with the milk quality and lambs daily gain (P < 0.05). Conclusions: This study revealed the characteristic succession changes in the rumen microbiota and its metabolites at different reproductive periods in sheep breeds and their regulation of reproductive hormone and immune levels and identified their potential effects on the growth and development of offspring lambs. The findings provide valuable insights into the health and feeding management of different sheep breeds during the reproductive stage. Cnu7uEJBESQuA-vs1kGzfa Video Abstract [ABSTRACT FROM AUTHOR]

Background: The aim of this study is to investigate the impact of arginine on immune function and postoperative complications in colorectal cancer (CRC) patients. Methods: We conducted a comprehensive search to identify eligible RCTs in various databases, such as PubMed, Cochrane Library, EMBASE, Web of Science, MEDLINE, China National Knowledge Infrastructure (CNKI), Wanfang, VIP Medicine Information System (VIP), and Chinese Biomedical Database (CBM). This study aimed to examine IgA, IgG, and IgM levels as well as CD4+ and CD8+ counts as well as the CD4+/CD8+ ratio. Anastomotic leaking, length of stay (LOS), and surgical site infection (SSI) were included as secondary outcomes. Stata (StataCorp, version 14.0) was utilized for data analysis. To ensure the results were reliable, we used meta-regression, sensitivity analysis, and publication bias analysis. Results: A total of 24 publications (including 1883 patients) out of 681 that were retrieved fulfilled the inclusion criteria. The arginine group showed notable improvements in humoral immunity, with gains in IgA (SMD=0.45, 95% CI: 0.30-0.60), IgG (SMD=0.80, 95% CI: 0.64-0.96), and IgM (SMD=0.66, 95% CI: 0.39-0.93). With regards to cellular immunity, the arginine group exhibited a substantial increase in the CD4+ T cell count (SMD = 1.03, 95% CI: 0.67-1.38) compared to the control group. However, the CD4+/CD8+ ratio decreased significantly (SMD=1.37, 95% CI: 0.88-1.86) in the same arginine group, indicating a change in the balance between these two cell types. Additionally, the CD8+ T cell count showed a notable decrease (SMD=-0.70, 95% CI: -1.09 to -0.32) in the arginine group when compared to the control group. Anastomotic leakage was also considerably lower in the arginine group (SMD=-0.05, 95% CI: -0.08 to -0.02), the rate of SSIs was lower (RR = -0.02, 95% CI: -0.05-0), and the length of time patients spent in the hospital was shorter (SMD=-0.15, 95% CI: -0.38 to -0.08). Conclusions: After radiation treatment for CRC, arginine improves immune function and decreases the risk of infection problems. Trial registration: Registration with PROSPERO for this meta-analysis is number CRD42024520509. [ABSTRACT FROM AUTHOR]

Ethnopharmacological relevance: Danggui Buxue decoction (DBD) is a traditional Chinese herbal formula. According to the theory of traditional Chinese medicine, the combination of Astragali Radix (AR) and Angelica sinensis (AS) is a classic prescription of tonifying qi and enriching blood. DBD has the functions of hematopoietic, immune enhancement and inflammation inhibition, usually used to treat qi and blood deficiency symptoms. Aim of the study: Cyclophosphamide (CY) can inhibit humoral and cellular immunity, leading to the overall immune disorder of the body, resulting in immunosuppressive (IS). Pre-laboratory studies confirmed the immunomodulatory effects of DBD, but its mechanisms have not been thoroughly studied. In this study, themain purpose was to determine the effects of DBD on the immune function and intestinal mucosal barrier function of IS mice induced by CY, and initially explored the immunomodulatory mechanism of DBD. Materials and Methods: 100 g of AR and 20 g of AS were accurately weighed and 0.5 g/mL of the DBD was obtained by boiling, filtration and rotary evaporation. Then, mice in the DBD group were administered 5 g/kg of DBD by gavage, positive group were administered 40 mg/kg of levamisole hydrochloride, whereas those in the control and model groups were given the corresponding volume of normal saline by gavage for 1 week. At the end of the experiment, blood, spleen, thymus, ileum and cecum contents of all the experimental mice were collected aseptically. IS mouse model induced by intraperitoneal injection of 80 mg/kg CY for three consecutive days. Pathomorphology was used to observe the physical barrier of the intestine, flow cytometry to detect splenic lymphocytes, immunohistochemistry to determine the content of intestinal barrier-associated proteins, ELISA to measure the secretion of ileal SIgA, qRTPCR to detect the mRNA expression of immune-related genes in the intestine, and high-throughput sequencing and analysis of cecum contents. Results: DBD alleviated spleen tissue damage and restored impaired immune functions, such as increased thymus index and CD4+/CD8+ subsets of spleen lymphocytes. In addition, DBD could increase ileum villi length and the ratio of villi length to crypt depth (V/C), and decrease crypt depth. Moreover, DBD administration up-regulated the expression of ZO-1, Occludin, Claudin-1, MUC-2 mRNA in ileum. And the secretions of sIgA and ZO-1 in ileum were also significantly improved. Furthermore, the administration of DBD can increase the diversity of gut microbiota, improve the composition of intestinal flora and increase the relative abundance of beneficial genus, such as Bacteroides. Conclusion: DBD alleviated CY-induced immune damage by decreasing the ratio of spleen index to CD4+/CD8+ of T lymphocyte subsets. And the intestinal barrier function of mice was by improves improving the intestinal morphology of the ileum and up-regulating the expression levels of ZO-1, MUC-2 and SIgA. DBD regulates CY-induced gut microbiota dysregulation in mice by increasing species diversity and richness, regulating the phylum, class and order levels of Bacteroidetes. [ABSTRACT FROM AUTHOR]

The experiment aimed to explore the effects of whole-plant millet on the semen quality, serum reproductive hormones, antioxidant capacity, and immune function of male rabbits. Thirty-six adult Ira bucks were randomly divided into six groups, with six replicates per group, and housed individually. The control group and groups I to V were fed diets with 0, 5%, 10%, 15%, 20%, and 25% whole-plant millet, respectively, as an equivalent replacement for alfalfa meal. The preliminary trial lasted for seven days, and the formal experiment lasted for 90 days. The results showed that as the experimental time extended, the sperm deformity rate in each group showed a downward trend. Compared with the 30th day, the sperm motility and sperm density of each group were significantly increased on the 60th and 90th days (P<0.05). At the 60th and 90th days, compared with groups IV and V, the sperm motility and sperm density in the control group and groups I to III were significantly increased (P<0.05). Compared with groups IV and V, the content of testosterone (TESTO) in groups II and III was significantly increased (P<0.05). Compared with the control group, the malondialdehyde (MDA) content in groups IV and V was significantly decreased (P<0.05), the content of immunoglobulin A (IgA) in groups III to V was significantly increased (P<0.05). The study indicates that whole-plant millet has a positive regulatory effect on the semen quality, serum reproductive hormones, antioxidant capacity, and immune function of male rabbits. Considering the comprehensive production performance and economic benefits, it is best to use whole-plant millet straw as a substitute at a level of 15%. [ABSTRACT FROM AUTHOR]

The experiment was conducted to investigate the effects of acute stress with different nitrite concentrations on immunity and gill Na+/K+-ATPase activity of Litopenaeus vannamei. Litopenaeus vannamei with average weight of (1.68±0.23) g were selected. The nitrite concentrations were set as 0 (Control group),0.4, 0.8, 1.6, 3.2 mg/L respectively. The acute stress test lasted for 96 h. Hepatopancreas immune function and gill Na+/K+-ATPase activity were measured at 0, 12, 24, 48, 72, 96 h, respectively. The result showed that the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), acid phosphatase (ACP), alkaline phosphatase (AKP), and lactate dehydrogenase (LDH) in the liver pancreas of Litopenopenus vannamei in stress groups showed an overall trend of increasing first and then decreasing with the extension of stress time. In the 3.2 mg/L group, the activities of SOD, CAT, GSH-Px, and ACP in the liver pancreas of Litopenopenus vannamei all dropped to the level of the control group after 96 hours of stress. The activity of LDH dropped to the level of the control group after 24 hours of stress and then continued to decrease significantly below the level of the control group (P<0.05). Except for the 0.4 mg/L group, where the content of malondialdehyde (MDA) in the hiver pancreas of Litopenopenus vannamei dropped to the level of the control group after 96 hours of stress, the MDA content in all other groups was significantly higher than that of the control group during the 96 hours of stress (P<0.05). Within 96 hours of stress, the activity of Na+/K+-ATPase in the gills of Litopenopenus vannamei in the 0.4 mg/L group continued to rise; the activity of Na+/K+-ATPase in the gills of Litopenopenus vannamei in the 0.8 to 3.2 mg/L groups showed a trend of initial activation followed by inhibition with the extension of stress time, and in the 3.2 mg/L group, it dropped to the level of the control group after 96 hours of stress. The study shows that the immune function and gill Na+/K+-ATPase activity of Litopenaeus vannamei were significantly affected under acute nitrite stress of 0.4 to 3.2 mg/L. When the salinity is (24.0±1.0) parts per thousand, it is necessary to control the nitrite content within 0.4 mg/L during the healthy aquaculture process of the Litopenaeus vannamei.

This study investigates the impact of perioperative factors on patients' immune functions including physiological condition, surgical strategy, anesthesia methodology, intraoperative usage of anesthetics, blood transfusion, intraoperative body temperature, and inspired oxygen concentration. Results demonstrate that the individual perioperative factors have varying degree of impact, while their combined effect may cause changes in patients' immune function. The study outcomes suggest that patient's immune function must be assessed prior to the surgery based on individual characteristics. The surgical and anesthetic methods are accordingly selected. During the surgery, prudent usage and monitoring of factors like anesthesia techniques, anesthetics, inhaled oxygen concentration, blood transfusion, and patient's body temperature are vital for minimizing the immune system disruptions. These findings practically guide regarding the optimization of perioperative care strategies and mitigation of immunosuppression risks. [ABSTRACT FROM AUTHOR]

Objective: To observe the effects of sevoflurane combine with remifentanil on awakening quality, stress response and cellular immune function in children with indirect inguinal hernia undergoing laparoscopic operation. Methods: 102 children with indirect inguinal hernia received in our hospital from November 2023 to January 2024 were divided into control group (51 cases, anesthesia regimen was remifentanil) and observation group (51 cases, anesthesia regimen was Propofol combined with remifentanil) by random number table method. The hemodynamic indexes [heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP)], Awakening situation [time of awakening, extubation and respiratory recovery], stress response indexes (blood glucose and plasma cortisol) and cellular immune function (CD4", CD8", CD4/CD8") were compared in two groups, the incidence of adverse reactions was statistically compared in two groups. Results: HR, SBP and DBP at 10 min after skin incision and extubation in observation group were higher than those in control group (P<0.05). The time of awakening, extubation and respiratory recovery in observation group were shorter than those in control group (P<0.05). The blood glucose and cortisol in observation group were lower than those in control group at the time of skin incision and extubation (P<0.05). 12 h after operation, CD4 and CD4/CD8+ in observation group were higher than those in control group, and CD8 was lower than that in control group (P<0.05). The total incidence of adverse reactions: control group was 9.80%; observation group was 11.76%, there was no difference in two groups (P>0.05). Conclusion: Remifentanil and sevoflurane are selected as anesthetic drugs for children with indirect inguinal hernia undergoing laparoscopic operation, which can maintain hemodynamic stability, improve awakening quality, reduce stress response and relieve immunosuppression.

Gwakhyangjeonggi-san (GJS) is a traditional herbal medicine used in East Asia for the treatment of symptoms involving lower intestinal abnormalities; however, the effects of GJS on innate immunity and its cellular mechanisms of action have not been elucidated. In this study, we assessed the immune-enhancing activity and underlying mechanisms of GJS using RAW 264.7 murine macrophages. The results showed that GJS treatment significantly increased the secretion of nitric oxide and cytokines and their mRNA expression in macrophage RAW 264.7 cells without causing cytotoxicity. GJS treatment also significantly increased the production of reactive oxygen species, as well as inducing phagocytic activity, adhesion function, and migration ability, all of which improved the immune response. In addition, GJS activated nuclear factor-κB by promoting the phosphorylation and degradation of inhibitor of nuclear factor-κB alpha. Furthermore, GJS markedly increased the phosphorylation of mitogen-activated protein kinase in RAW 264.7 cells. These findings indicate that GJS has potential value as a dietary supplement for strengthening immunity. [ABSTRACT FROM AUTHOR]

The first 1000 days of life is a critical period of development in which adverse circumstances can have long-term consequences for the child’s health. Maternal immune activation is associated with increased risk of neurodevelopmental disorders in the child. Aberrant immune responses have been reported in individuals with neurodevelopmental disorders. Moreover, lasting effects of maternal immune activation on the offspring’s immune system have been reported. Taken together, this indicates that the effect of maternal immune activation is not limited to the central nervous system. Here, we explore the impact of maternal immune activation on the immune system of the offspring. We first describe the development of the immune system and provide an overview of reported alterations in the cytokine profiles, immune cell profiles, immune cell function, and immune induction in pre-clinical models. Additionally, we highlight recent research on the impact of maternal COVID-19 exposure on the neonatal immune system and the potential health consequences for the child. Our review shows that maternal immune activation alters the offspring’s immune system under certain conditions, but the reported effects are conflicting and inconsistent. In general, epigenetic modifications are considered the mechanism for fetal programming. The available data was insufficient to identify specific pathways that may contribute to immune programming. As a consequence of the COVID-19 pandemic, more research now focuses on the possible health effects of maternal immune activation on the offspring. Future research addressing the offspring’s immune response to maternal immune activation can elucidate specific pathways that contribute to fetal immune programming and the long-term health effects for the offspring.

The Rab family of proteins is involved in organelle regulation, trafficking, signal transduction, mitosis, phagocytosis, growth differentiation, cytoskeleton protein depolymerization and other cellular functions and abnormal expression has been associated with many pathologies, including cancer. Previous work has focused on Rab function in higher animals but fish, crustaceans and other aquatic animals also express the Rab proteins. The current review summarizes research progress on Rab proteins, focusing on immune defense against pathogens in aquatic animals. Some differences in Rab protein function between aquatic and higher animals were found and greater involvement in the fish and crustacean immune system than that of higher animals. Novel insights into Rab protein in aquatic animals are offered with implications for the development of aquaculture strategies. [ABSTRACT FROM AUTHOR]

This study aimed to assess the effects of substituting zinc oxide with terminalia chebula extract (TCE) on growth performance, antioxidant capacity, immune function, and intestinal health in weaned pigs. Initially, 72 weaned Duroc × Landrace × Large White piglets, 28 days old with an initial weight of 7.43 ± 0.14 kg, equally divided by gender, were randomly assigned into three groups, with six replicates and four piglets per replicate. They were fed a basal diet (CON group), a diet containing 2 g/kg zinc oxide (ZnO group), or 2 g/kg TCE (TCE group) for a duration of 28 days. Subsequently, to further confirm the most appropriate levels of TCE in piglets, 96 piglets of the same breeds and age, with an initial weight of 7.42 ± 0.12 kg, also equally divided by gender, were randomly assigned into four groups, each with six replicates and four piglets per replicate, and fed a basal diet (CON group), or diets supplemented with 1 g/kg TCE (LTCE group), 2 g/kg TCE (MTCE group), or 4 g/kg TCE (HTCE group) for a duration of 28 days. The results demonstrated that both TCE and ZnO reduced diarrhea rates (p = 0.001) and enhanced average daily gain (ADG) (p = 0.014) compared to the control group. TCE at 1 g/kg and 4 g/kg reduced the feed to gain ratio (p = 0.050). Dietary supplementing with TCE and ZnO increased serum total antioxidant capacity (T-AOC) (p = 0.020). Various doses of TCE also increased jejunal IgA (p = 0.000) levels and IL-10 expression (p = 0.004), and decreased the levels of TNF-α in both serum (p = 0.043) and jejunal mucosa (p = 0.000). Notably, TCE reduced the crypt depth (CD) of the duodenal (p = 0.007) and increased the villus height (VH) of the ileal (p = 0.045), and with increased dosage, there was a rise in the villus height to crypt depth ratio (VH:CD) in the duodenum (p = 0.000) and jejunum (p = 0.001). Higher abundances of Lactobacillaceae (p = 0.000) and lower levels of Streptococcaceae (p = 0.000) and Peptostreptococcaceae (p = 0.035) in cecal contents were fed the ZnO and TCE pigs compared with CON pigs. Therefore, TCE was firstly presented as being able to replace zinc oxide, improve intestinal morphology, and enhance antioxidant and immune functions, thus safeguarding intestinal mucosal health and promoting piglet growth.

Objective: To investigate the protective effects of different doses of Fomes officinalis Ames polysaccharides (FOP) on intestinal flora and immune function in exercise-induced immunosuppression (EIS) rats. Methods: Fifty SPF male SD rats aged 7 to 8 weeks were randomly divided into control group (NC group), exercise training group (Ex group), exercise training+low-dose FOP group (LFOP group, 40 mg/(kg·d)), exercise training+medium-dose FOP group (MFOP group, 60 mg/(kg·d)) and exercise training+high-dose FOP group (HFOP group, 80 mg/(kg·d)). Ex group and FOP group were trained on the treadmill for 6 weeks to construct EIS model. LFOP, MFOP and HFOP groups were given FOP after each training. After the intervention, serum IgG, IgM, IL-6, IL-10, INF-γ, TNF-α, LPS levels and intestinal short-chain fatty acid content were detected by enzyme-linked immunosorbent assay. The number of serum CD4+ and CD8+ was detected by cell analyzer. 16S rDNA was used to detect the structural changes of intestinal flora. Western blot was used to detect the protein expression of ZO-1, Occludin, Claudin4 in the colon tissue. Results: Compared with Ex group, serum IgG, IgM, INF-γ, TNF-α, CD4+ and CD8+ of rats in LFOP, MFOP and HFOP groups were significantly increased (P

Objective: To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP). Methods: Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats. Results: The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC. Conclusion: SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity.

Methods From three groups of breast cancer cell lines（MDA-MB-231，HCC1937， MDA-MB-468）,real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot were detected and screened that the breast cancer cell line was HCC1937,which with high expression of HLA-G, and low expression of fibrinogen-like protein 1 (FGL1), programmed death factor ligand 1 (PD-L1), as well as sialic acid-binding immunoglobulin-like lectin 15 (SIGLEC15) . HCC1937 cells were divided into NC group (control group) and KD group (knockdown group), and RNA interference (RNAi) lentiviral vectors were constructed and transfected into KD cells to knock down HLA-G gene, and the verification was carried out. HCC1937 cells were treated with HLA-G antibody blocking/nonblocking, and Jurkat cells were treated with CD3 and CD28 activation/non-activation, respectively, and the two types of cells were co-cultured into 8 groups: NC--, KD--, NC+-, KD+-, NC-+, KD-+, NC++, and KD++ groups. Cell scratch assay, MTT and ELISA method were used to detect cell migration rate, proliferation rate, and interferon (IFN)-γ and interleukin (IL)-2 levels in cell supernatants, respectively. Results RT-qPCR showed that the HLA-G gene was successfully knocked down in HCC1937 cells. Compared with the NC++ group, the migration rate of the KD++ group was significantly increased (P＜0.05), but there was no statistical difference in the cell proliferation rate between each pair of co-culture groups (P＞0.05). The concentration of IFN-γ in the KD++ group was lower than that in the NC++ group and the NC-+ group (P＜0.05), but there was no significant difference in the concentration of IL-2 between each pair of co-culture groups (P＞0.05). Conclusion HLA-G in TNBC cells may promote the secretion of IFN-γ by activing T cells, and IFN-γ can inhibit the immune function of T cells and promote tumor metastasis after HLA-G decreased."

Abstract To assess the safety and efficacy of fecal microbiota transplantation (FMT) as an adjunctive therapeutic intervention for IgA nephropathy (IgAN). Fifteen patients with IgA nephropathy were recruited based on inclusion and exclusion criteria and underwent FMT using enteric microbial capsules. Clinical indicators, intestinal microbiota and metabolomic profiles, as well as changes in serum immune cells and cytokines, were monitored before and after FMT. No severe adverse reactions were observed in the subjects. After FMT, there was a reduction in the 24-h urinary protein quantification in subjects. The relative abundances of Phocaeicola_vulgatus, Bacteroides_uniformis, Prevotella_copri, Phocaeicola_dorei, Bacteroides_ovatus, Bacteroides_xylanisolvens, Parabacteroides _distasonis, Bifidobacterium_pseudocatenulatum, Bacteroides_sp._HF-162, and Bifidobacterium_longum changed after FMT. In terms of intestinal metabolites, the levels of acylcarnitine18:0 (ACar.18:0), cotinine, N-arachidonoyl-L-serine, phosphatidylcholine (PC. (18:3e/22:6)), serotonin, and fumagillin showed significant changes. Flow cytometry analysis showed the absolute count of plasma B cells decreased in subjects, and this change correlated with alterations in the intestinal microbiota and metabolites. This study preliminarily evaluates the safety and efficacy of FMT in patients with IgAN. No significant adverse reactions were observed, and the administration of FMT alongside ACEI/ARB therapy was effective in reducing urinary protein levels in patients with IgAN, a process that may be associated with B-cell immunity.

Objective: To investigate the impact of giant salamander protein peptide (CGS) and its Maillard reaction product (CGSXyU) on lowering blood glucose and lipid levels in type Ⅱ diabetic mice and enhancing immunomodulatory functions in immunosuppressed mice, and anti-fatigue effects in normal mice. Methods: Mice were randomly assigned to a blank control group, a model control group, a positive control group (200 mg/kg metformin), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a high-dose sample group (CGS/CGSXyU-H, 200 mg/kg). Following the successful induction of diabetes with 100 mg/kg alloxan, the mice underwent gavage treatment for 3 weeks, after which their fasting blood glucose levels, serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were measured. Mice were randomly assigned to a blank control group, a model control group, a positive control group (50 mg/kg levamisole), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a high-dose sample group (CGS/CGSXyU-H, 200 mg/kg). Following successful modeling with 100 mg/kg cyclophosphamide, the mice underwent gavage for three weeks, during which their body weights were recorded, and changes in organ indices and cytokine levels were assessed. Similarly, mice were randomly divided into a blank control group, a positive control group (200 mg/kg taurine), a low-dose sample group (CGS/CGSXyU-L, 50 mg/kg), and a high-dose sample group (CGS/CGSXyU-H, 200 mg/kg). They were subjected to gavage for four weeks, after which the mice's weight-bearing swimming time, urea nitrogen levels, creatine kinase activity, serum lactate levels, and antioxidant enzyme activity were measured. Results: The CGS/CGSXyU-L/H treated group of mice exhibited reduced fasting blood glucose concentration, serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C), along with elevated high-density lipoprotein cholesterol (HDL-C) levels. CGSXyU-H significantly enhanced the body weight (P

Abstract Introduction This study analyzed and discussed the characteristics of peripheral blood lymphocytes (PBLs) in patients with endometrial carcinoma (EC) to explore the PBLs’ clinical application value. Methods This single-center case‒control study analyzed the clinical data of patients with EC and uterine fibroids who underwent surgery at the First Affiliated Hospital of Chongqing Medical University between October 2018 and October 2023 retrospectively. The Center for Clinical Molecular Medical Detection of our hospital performed PBLs detection using flow cytometry, and recorded the detection results in the electronic medical records system. Between-group and subgroup comparisons of PBLs in patients with EC were analyzed using t-test or Mann–Whitney U test. The effect of surgery on PBLs in patients with EC was assessed using a paired t-test or the Wilcoxon signed rank test. Results The immune function of patients with EC was significantly lower than that of healthy people (P < 0.05) and those with benign uterine diseases (P < 0.05) and was related to body mass index (BMI), hypertension, diabetes, and blood lipids (P < 0.05). In patients with EC, the PBLs counts decreased significantly after surgery (P < 0.05) and more kinds of lymphocytes were affected in the laparoscopic surgery group than in the open surgery group. Conclusions With the decrease of PBLs counts, the immune status of patients with EC is impaired. Metabolic syndrome (Mets), including obesity, hypertension, diabetes, and high blood lipids, also affects the immune function of patients with EC. And for EC patients, the effect of laparoscopic surgery is greater than that of open surgery. PBLs has the potential to be one of indicator during the diagnosis and treatment of EC. Trial registration This study was retrospectively registered by the Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (approval number K2023-578).

Abstract Background The microbiota and metabolites in the gastrointestinal tracts of female animals at different reproductive periods are very important to the growth, development, and health of themselves and their offspring. However, the changes in the gastrointestinal microbiota and metabolites throughout reproductive period of different sheep breeds and their effects on the growth and development of offspring lambs are still unclear. Hence, this study presents an assessment of the reproductive hormone levels, immune levels, rumen microbiota, and metabolites in Hu sheep and Suffolk ewes at different reproductive periods and their effects on the growth and development of offspring lambs. Results Hu sheep and Suffolk during non-pregnancy, pregnancy, and lactation were used as the research objects to determine reproductive and immune indexes of ewes at different periods, analyze rumen microbiome and metabolome, and track the growth performance and development of offspring lambs. The results showed that the reproductive hormone and immune levels of Hu sheep and Suffolk underwent adaptive changes across different reproductive periods. Compared with non-pregnancy, the microbial energy metabolism and lipid metabolism function decreased during Hu sheep pregnancy, and energy metabolism function decreased during lactation. In Suffolk, energy metabolism, glycan biosynthesis, and metabolism function were enhanced during pregnancy, and the metabolism of cofactors and vitamins was enhanced during lactation. Prevotella increased in Suffolk during pregnancy and lactation (P < 0.05) and was positively correlated with the birth weight and body size of the lambs (P < 0.05). Moreover, the abundances of Butyrivibrio and Rikenellaceae_RC9_gut_group during pregnancy were positively correlated with the intestinal immunity of the offspring lambs (P < 0.05), thereby regulating the intestinal immunity level of the lambs. Metabolomic analysis revealed that the protein digestion, absorption, and amino acid metabolism of Hu sheep were enhanced during pregnancy, which provided amino acids for the growth and development of pregnant ewes and fetuses and was significantly correlated with the birth weight, body size, and intestinal immunity of lambs (P < 0.05). Simultaneously, there was an increase in acetate and propionate during the pregnancy and lactation period of both Hu sheep and Suffolk, providing energy for ewes during reproductive period. Moreover, the microbiota during the lactation period was significantly correlated with the milk quality and lambs daily gain (P < 0.05). Conclusions This study revealed the characteristic succession changes in the rumen microbiota and its metabolites at different reproductive periods in sheep breeds and their regulation of reproductive hormone and immune levels and identified their potential effects on the growth and development of offspring lambs. The findings provide valuable insights into the health and feeding management of different sheep breeds during the reproductive stage. Video Abstract

Abstract Background The aim of this study is to investigate the impact of arginine on immune function and postoperative complications in colorectal cancer (CRC) patients. Methods We conducted a comprehensive search to identify eligible RCTs in various databases, such as PubMed, Cochrane Library, EMBASE, Web of Science, MEDLINE, China National Knowledge Infrastructure (CNKI), Wanfang, VIP Medicine Information System (VIP), and Chinese Biomedical Database (CBM). This study aimed to examine IgA, IgG, and IgM levels as well as CD4+ and CD8+ counts as well as the CD4+/CD8+ ratio. Anastomotic leaking, length of stay (LOS), and surgical site infection (SSI) were included as secondary outcomes. Stata (StataCorp, version 14.0) was utilized for data analysis. To ensure the results were reliable, we used meta-regression, sensitivity analysis, and publication bias analysis. Results A total of 24 publications (including 1883 patients) out of 681 that were retrieved fulfilled the inclusion criteria. The arginine group showed notable improvements in humoral immunity, with gains in IgA (SMD=0.45, 95% CI: 0.30-0.60), IgG (SMD=0.80, 95% CI: 0.64-0.96), and IgM (SMD=0.66, 95% CI: 0.39-0.93). With regards to cellular immunity, the arginine group exhibited a substantial increase in the CD4+ T cell count (SMD = 1.03, 95% CI: 0.67-1.38) compared to the control group. However, the CD4+/CD8+ ratio decreased significantly (SMD=1.37, 95% CI: 0.88-1.86) in the same arginine group, indicating a change in the balance between these two cell types. Additionally, the CD8+ T cell count showed a notable decrease (SMD=-0.70, 95% CI: -1.09 to -0.32) in the arginine group when compared to the control group. Anastomotic leakage was also considerably lower in the arginine group (SMD=-0.05, 95% CI: -0.08 to -0.02), the rate of SSIs was lower (RR = -0.02, 95% CI: -0.05-0), and the length of time patients spent in the hospital was shorter (SMD=-0.15, 95% CI: -0.38 to -0.08). Conclusions After radiation treatment for CRC, arginine improves immune function and decreases the risk of infection problems. Trial registration Registration with PROSPERO for this meta-analysis is number CRD42024520509.

ABSTRACTThe COVID-19 pandemic has significantly impacted human life, posing serious physical and psychological threats, particularly to the elderly. While individuals of all ages are susceptible to contracting COVID-19, older people face a heightened risk of developing various diseases due to age-related immunophysiological changes and preexisting health conditions. The interplay between immune health and physical activity is believed to hold even greater significance during a pandemic. Recent findings from our research indicate that the intervention of square stepping exercise (SSE), characterized by a rhythmic and controlled stepping pattern, resulted in increased levels of Brain-Derived Neurotrophic Factor (BDNF) in the elderly. BDNF, known to influence not only nerve cells but also immune cells, suggests a potential link between SSE and immune system modulation. Consequently, this exercise regimen holds promise in counteracting age-related immunophysiological changes, fine-tuning immune responses, and mitigating the severity of potential new virus outcomes, such as ‘Disease X.’ This review aims to underscore the significance of integrating SSE as a home-based program, serving as a potent tool to enhance immune resilience, prepare for future potential pandemics, and empower older individuals during challenging times. Through the practice of SSE, older adults may strengthen their ability to navigate the challenges posed by pandemics and maintain a sense of control over their well-being.

Purpose: Exercise has transient effects on the immune system that could influence infection risk and tissue recovery after exercise. Little is known about how the menstrual cycle interacts with the immune responses to acute exercise. This exploratory study sought to evaluate the effect of menstrual-cycle phase on peripheral blood mononuclear cell counts before and immediately after a bout of intense aerobic exercise. Methods: Seven naturally menstruating women (age: 27 [3] y) completed three 5-km cycling time trials coinciding with the early-follicular, late-follicular, and mid-luteal stage, confirmed by hormonal measurement. Venous blood samples were taken and examined for the presence of immune cell types using flow cytometry. Results: Reductions in circulating CCR7+CD45RA+ naïve CD4+ T cells, CD4+CD25+ regulatory T cells, and CD56+CD57+ natural killer cells observed during the early-follicular phase were attenuated when exercise was performed during the late-follicular phase. Similarly, reductions in circulating CD56+CD57+ natural killer cells and CD14+TLR4+ monocytes following exercise in the early-follicular phase were abolished when exercise was performed in the midluteal phase. Conclusions: These preliminary findings indicate that the effect of acute high-intensity exercise on immune-cell mobilization and activation varies across the menstrual cycle, potentially impacting the anti-inflammatory effects of regulatory T cells and the cell-mediated effects of both natural killer CD57+ cells and monocytes expressing TLR4.

However, the impact of the Chinese visceral adiposity index (CVAI) on the efficacy of SARS-CoV-2 vaccines remains poorly understood. This study aims to explore the impact of CVAI on the production of neutralizing antibodies (NAb) in inactivated SARS-CoV-2 vaccines and the potential mechanism, thereby optimizing vaccination guidance.Methods: In this cross-sectional study, 206 health workers (completed two SARS-CoV-2 vaccination on February 8th and March 10th, 2021, respectively) were recruited. All baseline anthropometric parameters of the participants were collected, and venous blood samples were obtained 6 weeks later to measure peripheral innate immune cells, inflammatory cytokines, and NAb titers against SARS-CoV-2. CVAI were calculated according to the formula and divided participants into two groups depending on CVAI median.Results: The median NAb titer among healthcare workers was 12.94 AU/mL, with an efficacy of 87.86% for the SARS-CoV-2 vaccine. NAb titers were lower in the CVAI dysfunction group than in the CVAI reference group (median: 11.40 AU/mL vs 15.57 AU/mL), the hsCRP levels (median: 0.50 mg/L vs 0.30 mg/L) and peripheral monocyte count (mean: 0.47 × 109/L vs 0.42 × 109/L) in the CVAI dysfunction group were higher than in the CVAI reference group. Additionally, CVAI showed positive correlations with hsCRP, monocytes, lymphocytes, and B-lymphocytes, and a negative correlation with NAb titers.Conclusion: CVAI may inhibit SARS-CoV-2 neutralizing antibody expression through inducing immune dysfunction and chronic inflammation. Thus, more attention should be paid to the vaccination for high CVAI population to improve the effectiveness of vaccination, which could provide more robust support for COVID-19 epidemic prevention and control.Keywords: Chinese visceral adiposity index, immune function, chronic inflammation, SARS-CoV-2 vaccine, neutralizing antibody

Abstract Purpose To explore the influence of circulating lymphocyte subsets, serum markers, clinical factors, and their impact on overall survival (OS) in locally advanced nasopharyngeal carcinoma (LA-NPC). Additionally, to construct a nomogram predicting OS for LA-NPC patients using independent prognostic factors. Methods A total of 530 patients with LA-NPC were included in this study. In the training cohort, Cox regression analysis was utilized to identify independent prognostic factors, which were then integrated into the nomogram. The concordance index (C-index) was calculated for both training and validation cohorts. Schoenfeld residual analysis, calibration curves, and decision curve analysis (DCA) were employed to evaluate the nomogram. Kaplan-Meier methods was performed based on risk stratification using the nomogram. Results A total of 530 LA-NPC patients were included. Multivariate Cox regression analysis revealed that the circulating CD8+T cell, platelet-to-lymphocyte ratio (PLR), lactate dehydrogenase (LDH), albumin (ALB), gender, and clinical stage were independent prognostic factors for LA-NPC (p

Deoxynivalenol (DON) is a mycotoxin that is produced by various species of Fusarium and is ubiquitous in food and feed. At low concentrations, it can cause metabolic disorders in animals and humans and, at high concentrations, it can lead to pathological changes in the body. The impact of DON on human/animal health and animal productivity has thus attracted a great deal of attention around the world. DON causes severe damage to the intestine, including compromised intestinal barrier, mucosal damage, weakened immune function, and alterations in gut microbiota composition. These effects exacerbate intestinal infections and inflammation in livestock and poultry, posing adverse effects on overall health. Furthermore, research into biological methods for DON detoxification is a crucial avenue for future studies. This includes the utilization of adsorption, enzymatic degradation, and other biological approaches to mitigate DON’s impact, offering new strategies for prevention and treatment of DON-induced diseases. Future research will focus on identifying highly efficient detoxifying microorganisms or enzymes to reduce DON levels in food and feed, thereby mitigating its risks to both animals and human health.
