However, its effect on blood pressure during anesthesia induction in older adults remains unclear. To compare the effects of propofol and ciprofol on hypotension induced by general anesthesia in older adults.Patients and Methods: This prospective, single-center, double-blind, randomized, controlled clinical study enrolled 117 older adults undergoing surgery. Patients in the ciprofol group (group C) received an intravenous injection of ciprofol (0.3 mg/kg, n=57), while the propofol group (group P) received an intravenous injection of propofol (1.5 mg/kg, n=58). The primary outcome was the incidence of hypotension (mean arterial pressure (MAP) decreased by > 30% from baseline or MAP< 65 mmHg). Secondary outcomes included induction success rate (bispectral index (BIS) value ≤ 60 and Modified Observer’s Assessment of Alertness/Sedation Scale (MOAA/S) score ≤ 1), injection pain, number of drug additions, time to BIS 60, time to eyelash reflex disappearance, blood pressure changes, incidence of hypertension, tachycardia and BIS values before and after administration.Results: The incidence of induced hypotension was 26.3% (15/57) in group C and 48.3% (28/58) in group P (OR=0.383, 95% CI:175– 0.837, P =0.015). Group C had significantly lower injection pain incidence (5.3% vs 20.7%, OR=0.213, 95% CI: 0.057– 0.801, p=0.014). Both groups had a 100% induction success rate, with no significant difference in the number of additional doses. Post-intubation hypertension and tachycardia incidence were not significantly different. Group C showed less blood pressure decrease during induction and a deeper anesthesia level.Conclusion: Compared to propofol, ciprofol reduces the incidence of induced hypotension in older adults and maintains more stable blood pressure during induction. Additionally, ciprofol reduces injection pain and provides a good depth of anesthesia, making it a safe and effective option for anesthesia induction in older adults.Trial Registration ClinicalTrials.gov Identifier: ChiCTR2200066053.Keywords: ciprofol, propofol, bispectral index, BIS, hypotension

The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), objective response rate (ORR) and disease control rate (DCR).Results: Between January 2020 and December 2022, a total of 136 patients with initially uHCC received triple combination therapy, with 76 in the BP1-HAIC group and 60 in the BPL-HAIC group. The median PFS for the entire cohort was 11.1 months (95% CI, 8.0– 13.7 months), and the median OS was 22.4 months (95% CI, 21.3- not reached). Comparative analysis revealed no significant differences in PFS (HR, 0.91, P = 0.69) or OS (HR, 0.71, P = 0.31) between the BP1-HAIC and BPL-HAIC groups. The ORR was 46.3% per RECIST v1.1 and 66.9% per mRECIST, with a DCR of 83.1% under both criteria. Common adverse events (AEs) included hypoalbuminemia and elevated aspartate/alanine aminotransferase, with 5.1% (7/136) experienced upper gastrointestinal bleeding. Multivariate Cox analysis identified tumor number and BCLC stage as independent prognostic factors for OS, and tumor number for PFS.Conclusion: Triple combination therapy demonstrated significant therapeutic efficacy and tumor response in initially uHCC. No notable differences in outcomes were observed between the BP1-HAIC and BPL-HAIC groups. AEs were manageable in clinical practice.Keywords: hepatocellular carcinoma, immune checkpoint inhibitor, bevacizumab, hepatic arterial infusion chemotherapy, adverse event

Disseminated Intravascular Coagulopathy (DIC) represents a critical complication of sepsis, contributing to increased mortality and economic burden. Despite various prognostic scoring systems, there is a lack of a specific model for DIC prediction in sepsis patients.Methods: This observational study included 336 sepsis patients. Clinical and laboratory data were collected, and prognoses were defined according to established criteria.Results: We enrolled 336 patients, with 304 in the non-DIC group and 32 in the DIC group. Patients with DIC had notably lower platelet (PLT) and higher levels of prothrombin time (PT), lactate (LAC), and procalcitonin (PCT) compared to those without DIC. Univariate and multivariate analyses identified risk factors associated with the DIC, showing that PLT (OR = 0.985, 95% CI 0.978– 0.993, p < 0.001), PT level (OR = 1.140, 95% CI 1.004– 1.295, p = 0.044), and LAC (OR = 1.101, 95% CI 0.989– 1.226, p = 0.078) were related factors. A risk model was established, and its sensitivity and specificity in predicting DIC among sepsis patients were assessed by comparing it to the SOFA score. The area under the ROC curve for the model was 0.850, while the SOFA score was 0.813. With a model score >− 2.12, the sensitivity for predicting DIC was 84.4%, and the specificity was 75.0%.Conclusion: Our study introduces a predictive model for DIC detection in sepsis patients, emphasizing the need for clinicians to focus on patients with high model scores for timely intervention.Keywords: sepsis, risk model, disseminated intravascular coagulopathy, platelet, mortality

Plasmid sizes, plasmid conjugation abilities and the localization of carbapenemase genes were investigated. Whole-genome sequencing was performed for all strains and their molecular characteristics were analyzed. In vitro synergistic and bactericidal activities of the combination of aztreonam with CZA, MEV and IMR against these strains were determined using checkerboard assay and time-kill curve assay.Results: A total of 12 Enterobacterales strains producing dual-carbapenemases were collected, including nine K. pneumoniae, two P. rettgeri, and one E. hormaechei. The most common dual-carbapenemase gene pattern observed was bla(KPC-2+NDM-5) (n=4), followed by blaKPC-2+IMP-26 (n=3), bla(KPC-2+NDM-1) (n=2), bla(KPC-2+IMP-4) (n=1), bla(NDM-1+IMP-4) (n=1) and bla(KPC-2+KPC-2) (n=1). In each strain, the carbapenemase genes were found to be located on two distinct plasmids which were capable of conjugating from the original strain to the receipt strain E. coli J53. The results of the checkerboard synergy analysis consistently revealed good synergistic effects of the combination of ATM with CZA, MEV and IMR. Except for one strain, all strains exhibited significant synergistic activity and bactericidal activity between 2 and 8 hours.Conclusion: Dual-carbapenemase-producing Enterobacterales posed a significant threat to clinical anti-infection treatment. However, the combination of ATM with innovative β-lactam/β-lactamase inhibitor compounds had proven to be an effective treatment option.Keywords: dual-carbapenemase-producing enterobacterales, β‑lactam/β‑lactamase inhibitor combinations, aztreonam, checkerboard assay, time-kill curve

Their mothers were asked to complete a series of questionnaires including parental phubbing scale, problematic media use measure, and child behavior questionnaire. To investigate the moderating influence of children’s negative affectivity and effortful control, hierarchical linear regression analyses were conducted using SPSS 24.0. Simple slopes analyses and the Johnson–Neyman technique were further used to depict moderation effects.Results: Maternal phubbing was associated with higher levels of problematic media use in preschool children (β = 0.18, p < .001, [0.14, 0.22]). Children’s negative affectivity acts as a risk factor, exacerbating the adverse effects of maternal phubbing on children’s problematic media use (β = 0.05, t = 2.69, p < 0.05), whereas children’s effortful control acts as a protective factor, buffering the link between maternal phubbing and children’s problematic media use (β = − 0.10, t = − 5.00, p < 0.001).Conclusion: These results suggest that interventions seeking to promote appropriate digital development in preschoolers should take the child’s temperament into account and be complemented by active parental mediation and involvement.Keywords: maternal phubbing, problematic media use, negative affectivity, effortful control, preschoolers

Clinical outcomes including overall survival (OS), progression-free survival (PFS), tumor response and adverse events (AEs) were compared between the two groups. The risk factors affecting OS and PFS were also analyzed.Results: The median OS and PFS of the TACE-Len-T group were significantly longer than those of the TACE-Len group (Median OS: not reached vs 13.8 months, P< 0.001; Median PFS: 13.0 months vs 2.7 months, P< 0.001). The best overall objective response rate (ORR) was also better with TACE-Len-T treatment (ORR: 72.1% vs 29.4%, P< 0.001), and the disease control rate (DCR) significantly increased in the TACE-Len-T group (88.2% vs 48.5%, P< 0.001). Multivariate analyses revealed that TACE-Len treatment, tumor number > 3, and cTACE were independent risk factors for OS, whereas TACE-Len treatment was the only independent risk factor for PFS. The frequency and severity of AEs in the TACE-Len-T group were comparable to those in the TACE-Len group (any grade: 92.6% vs 91.2%, P=0.753; grade 3 or 4: 33.8% vs 32.3%, P=0.855).Conclusion: TACE-Len-T treatment significantly improved OS, PFS, ORR, and DCR over TACE-Len treatment, with a manageable safety profile in uHCC.Keywords: unresectable hepatocellular carcinoma, transarterial chemoembolization, lenvatinib, tislelizumab, immunotherapy

The present research focuses on the clinical significance of miR-379 in obesity-PCOS and attempts to elucidate its potential mechanisms.Methods: Healthy individuals (n = 46), obesity-PCOS (n = 92), and non-obesity PCOS (n = 31) subjects were enrolled. Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to examine the level of serum miR-379. The receiver operating characteristic (ROC) curve and logistic regressions were applied to reveal the diagnostic significance. Dual luciferase reporters were performed to validate the targeting relationships. And cell count kit (CCK-8) assay was used to detect cell proliferation.Results: Serum miR-379 was highly expressed in PCOS patients (P < 0.05), in especially obesity-PCOS patients. Higher miR-379 was associated with greater body mass index (BMI), higher bioavailable testosterone (bT), and greater insulin resistance (IR). Additionally, miR-379 was an independent risk factor for the development of obesity-PCOS. The sensitivity of miR-379 in identifying patients with obesity-PCOS from healthy or non-obesity-PCSO patients was 81.52% and 72.83%, and the specificity was 86.96% and 80.65%. Semaphorin 3 A (SEMA3A) was identified as a target of miR-379 and was reduced in the patients with obesity PCOS (P < 0.05). Inhibition of miR-375 reduced KGN proliferation, but this reduction was partially restored by silencing of SEMA3A (P < 0.05).Conclusion: Elevated miR-379 assists the diagnosis of obesity-PCOS and regulates the proliferation of KGN by targeting SEMA3A engaged in disease development.Keywords: obesity, PCOS, miR-379, diagnostic, SEMA3A

Different drug forms have received a lot of attention. However, systemic biodistribution induces efficacy and safety issues. Intratumoral delivery of agents might overcome these problems because of its abundant tumor accumulation and retention, thereby reducing side effects. Delivering hydrogels, nanoparticles, microneedles, and microspheres drug carriers directly to tumors can realize not only targeted tumor therapy but also low side-effects. Furthermore, intratumoral administration has been integrated with treatment strategies such as chemotherapy, enhancing radiotherapy, immunotherapy, phototherapy, magnetic fluid hyperthermia, and multimodal therapy. Some of these strategies are ongoing clinical trials or applied clinically. However, many barriers hinder it from being an ideal and widely used option, such as decreased drug penetration impeded by collagen fibers of a tumor, drug squeezed out by high density and high pressure, mature intratumoral injection technique. In this review, we systematically discuss intratumoral delivery of different drug carriers and current development of intratumoral therapy strategies.

This exploratory subgroup analysis aimed to explore the effects of acupuncture as an add-on therapy of selective serotonin reuptake inhibitors (SSRIs) for patients with AD or non-anxious depression (NAD).Patients and Methods: Four hundred and sixty-five patients with moderate-to-severe depression from the AcuSDep pragmatic trial were included in analysis. Patients were randomly assigned to receive MA+SSRIs, EA+SSRIs, or SSRIs alone (1:1:1) for six weeks. AD was defined by using dimensional criteria. The measurement instruments included 17-items Hamilton Depression Scale (HAMD-17), Self-Rating Depression Scale (SDS), Clinical Global Impression (CGI), Rating Scale for Side Effects (SERS), and WHO Quality of Life-BREF (WHOQOL-BREF). Comparison between AD and NAD subgroups and comparisons between groups within either AD or NAD subgroups were conducted.Results: Eighty percent of the patients met the criteria for AD. The AD subgroup had poorer clinical manifestations and treatment outcomes compared to those of the NAD subgroup. For AD patients, the HAMD response rate, remission rate, early onset rate, and the score changes on each scale at most measurement points on the two acupuncture groups were significantly better than the SSRIs group. For NAD patients, the HAMD early onset rates of the two acupuncture groups were significantly better than the SSRIs group.Conclusion: For AD subtype patients, either MA or EA add-on SSRIs showed comprehensive improvements, with small-to-medium effect sizes. For NAD subtype patients, both the add-on acupuncture could accelerate the response to SSRIs treatment. The study contributed to the existing literature by providing insights into the potential benefits of acupuncture in combination with SSRIs, especially for patients with AD subtypes. Due to its limited nature as a post hoc subgroup analysis, prospectively designed, high-quality trials are warranted.Clinical Trials Registration: ChiCTR-TRC-08000297.Keywords: anxious depression, non-anxious depression, acupuncture, SSRIs, subgroup analysis

The European Society for Medical Oncology (ESMO) guidelines for adult cancer pain recommend opioid titration through the parenteral route, usually the intravenous or subcutaneous route. Patient-controlled subcutaneous analgesia (PCSA) with hydromorphone needs further evaluation for opioid titration. This prospective multicenter study was designed to compare the efficacy and safety of hydromorphone PCSA with oral oxycontin tablets for opioid titration of cancer pain.Patients and Methods: Eligible patients with cancer pain were randomly assigned in a 1:1 ratio to the PCSA group or the oxycontin group for dose titration. Different titration methods were given in both groups depending on whether the patient had an opioid tolerance. The primary endpoint of this study was time to successful titration (TST).Results: A total of 256 patients completed this study. The PCSA group had a significantly lower TST compared with the oxycontin group (median [95% confidence interval (CI)], 5.5[95% CI:2.5– 11.5] hours vs.16.0 [95% CI:11.5– 22.5] hours; p< 0.001). The frequency (median; interquartile) of breakthrough pain (Btp) over 24 hours was significantly lower in the PCSA group (2.5;2.0– 3.5) than in the oxycontin group.(3.0; 2.5– 4.5) (p=0.04). The pain was evaluated by numeric rating scale (NRS) score at 12 hours after the start of titration. The pain score (median; interquartile) was significantly lower in the PCSA versus the oxycontin group (2.5;1.5– 3.0) vs 4.5;3.0– 6.0) (p=0.02). The equivalent dose of oral morphine (EDOM) for a successful titration was similar in both groups (p=0.29), but there was a significant improvement in quality of life (QoL) in both groups (p=0.03). No between-group difference in the incidence of opioid-related adverse effects was observed (p=0.32).Conclusion: Compared with oral oxycontin tablet, the use of PCSA with hydromorphone achieved a shorter titration duration for patients with cancer pain (p< 0.001), without significantly increasing adverse events (p=0.32).Keywords: cancer pain, opioid titration, oxycontin tablets, hydromorphone, patient-controlled subcutaneous analgesia

Stigma remains a formidable barrier for women living with HIV/AIDS, hindering their access to healthcare and exacerbating health disparities. Indeed, some women living with HIV/AIDS can successfully confront and overcome stigma. There remains a paucity of qualitative research exploring the stigma coping strategies of women living with HIV/AIDS in China. This study was aimed to gain the deeper understanding of stigma experienced by women living with HIV/AIDS and coping strategies.Patients and Methods: We recruited diverse participants using snowball sampling and purposive sampling. Semi-structured personal in-depth interviews were conducted with 30 women living with HIV/AIDS from December 2022 to June 2023. The samples were from four HIV/AIDS designated hospitals. The data were analyzed using the Colaizzi seven-step model.Results: The experiences of stigma among women living with HIV/AIDS included family role (wife/mother/grandmother) collapse and disgusted by family, resignation in being shunned by others, helplessness due to social exclusion, grief at being devaluated, and resentment for experiencing injustice. The coping strategies used to deal with stigma included concealing their conditions, avoiding socialization, and attempting to retaliate against society.Conclusion: Healthcare professionals are recommended to offer women living with HIV/AIDS effective emotional support and guidance to cope with stigma.

Plasma cells play a crucial role in immunotherapy.Patients and Methods: In our study, we used both single-cell RNA sequencing (scRNA-seq) and bulk sequencing techniques to analyze MM patients. We analyzed each sample using gene set variation analysis (GSVA) based on immune-related gene sets. We also conducted further analyses to compare immune infiltration, clinical characteristics, and expression of immune checkpoint molecules between the H-S100A9 and L-S100A9 groups of MM patients.Results: We identified eight subpopulations of plasma cells, with S100A9 plasma cells being more abundant in patients with 1q21 gain and 1q21 diploid. CellChat analysis revealed that GAS and HGF signaling pathways were prominent in intercellular communication of S100A9 plasma cells. We identified 14 immune-related genes in the S100A9 plasma cell population, which allowed us to classify patients into the H-S100A9 group or the L-S100A9 group. The H-S100A9 group showed higher ESTIMATE, immune and stroma scores, lower tumor purity, and greater immune checkpoint expression. Patients with 1q21 gain and four or more copies had the lowest ESTIMATE score, immune score, stroma score, and highest tumor purity. Drug sensitivity analysis indicated that the H-S100A9 group had lower IC50 values and greater drug sensitivity compared to the L-S100A9 group. Quantitative reverse transcription (RT-q) PCR showed significantly elevated expression of RNASE6, LYZ, S100A8, S100A9, and S100A12 in MM patients compared to the healthy control group.Conclusion: Our study has identified a correlation between molecular subtypes of S100A9 plasma cells and the response to immunotherapy in MM patients. These findings improve our understanding of tumor immunology and provide guidance for developing effective immunotherapy strategies for this patient population.Keywords: multiple myeloma, single-cell sequencing, bulk transcription, tumor immune microenvironment, S100A9

Its activation leads to the phosphorylation of downstream proteins such as acetyl-CoA carboxylase (ACC) and sterol regulatory element-binding protein-1 (SREBP1), subsequently inhibiting de novo fatty acid synthesis, thereby reducing intracellular triglyceride accumulation. MC is a compound found in extracts from Zanthoxylum armatum DC plants. Research has shown that MC can inhibit the differentiation of 3T3-L1 adipocytes through the CAMKK2-AMPK pathway. However, the biological effect of MC in HepG2 cells remains unknown.Methods: In this study, we utilized HepG2 cells to establish a model of MAFLD through FFAs stimulation. We investigated the biological effects of MC on HepG2 cells and studied its impact on lipid metabolism. Small interfering RNA was employed to explore the mechanism by which MC activates AMPK. Finally, molecular docking was conducted, establishing a model of the interaction between AMPK and MC.Results: We observed that MC can alleviate triglyceride accumulation in HepG2 cells. We observed the elevated p-AMPK/AMPK, P-ACC/ ACC, and elevated CPT1a after treatment of MC in HepG2 cells. The interference of CAMKK2 mRNA did not impact the ability of MC to phosphorylate AMPK. Compound C attenuates the ability of MC to increase p-AMPK. Molecular docking results led us to hypothesize that MC directly interacts with AMPK, resulting in AMPK phosphorylation and improved lipid accumulation in HepG2 cells.Keywords: AMPK, CAMKK2, FFAs, HepG2, methyl cinnamate, MAFLD

Neutrophils are the end effectors of IRI and activated neutrophils release neutrophil extracellular traps (NETs) to further amplify damage. Nevertheless, potential contributions of NETs in IRI remain incompletely understood. This study aimed to explore NET-related gene biomarkers in IRI during lung transplantation.Methods: Differential expression analysis was applied to identify differentially expressed genes (DEGs) for IRI during lung transplantation based on matrix data (GSE145989, 127003) downloaded from GEO database. The CIBERSORT and weighted gene co-expression network analysis (WGCNA) algorithms were utilized to identify key modules associated with neutrophil infiltration. Moreover, the least absolute shrinkage and selection operator regression and random forest were applied to identify potential NET-associated hub genes. Subsequently, the screened hub genes underwent further validation of an external dataset (GSE18995) and nomogram model. Based on clinical peripheral blood samples, immunofluorescence staining and dsDNA quantification were used to assess NET formation, and ELISA was applied to validate the expression of hub genes.Results: Thirty-eight genes resulted from the intersection between 586 DEGs and 75 brown module genes, primarily enriched in leukocyte migration and NETs formation. Subsequently, four candidate hub genes (FCAR, MMP9, PADI4, and S100A12) were screened out via machine learning algorithms. Validation using an external dataset and nomogram model achieved better predictive value. Substantial NETs formation was demonstrated in IRI, with more pronounced NETs observed in patients with PGD ≥ 2. PADI4, S100A12, and MMP9 were all confirmed to be up-regulated after reperfusion through ELISA, with higher levels of S100A12 in PGD ≥ 2 patients compared with non-PGD patients.Conclusion: We identified three potential NET-related biomarkers for IRI that provide new insights into early detection and potential therapeutic targets of IRI and PGD after lung transplantation.Keywords: ischemia reperfusion injury, neutrophil extracellular traps, lung transplantation, primary graft dysfunction, WGCNA, machine learning

The levels of hematological parameters during pregnancy can reflect inflammatory conditions in pregnant women. This study aims to describe the dynamic change of blood cell parameters from the first trimester (6– 12 weeks of gestation) to the second trimester (24– 28 weeks of gestation) and to investigate the associations of these biomarkers with the risk of GDM.Methods: This study was a prospective double-center study conducted in Beijing, China (clinical trial number: NCT03246295). Hematological parameters were tested four times during the follow-up. Logistic regression analysis and Receiver Operating Characteristic (ROC) curve analysis were used to explore the association and predictive ability of hematological parameters for GDM.Results: There were 258 of 1027 pregnant women in our study developed GDM. Among the 1027 pregnant women, white blood cells (WBC) gradually increased, and red blood cells (RBC), hemoglobin (HGB), and platelet (PLT) tended to decrease from the first trimester to second trimester. After adjusting for confounding factors, higher levels of RBC, HGB, and PLT in both early and middle pregnancy were positively associated with GDM risk, whereas the level of WBC was associated with GDM risk only in early pregnancy. WBC, RBC, HGB, and PLT in early and middle pregnancy were all correlated with fasting insulin (FINS) in early pregnancy.Conclusion: Higher levels of hematological parameters in early and middle pregnancy were associated with glucose metabolism in early pregnancy and the subsequent risk of GDM.Keywords: hematological parameters, gestational diabetes mellitus, inflammation, insulin resistance, prospective study

The main causes are drug and viral infections. Unfortunately, no expert consensus on treating this disease exists, and a standard therapy is absent. Up to now, glucocorticoids combined with gamma globulin are commonly used in clinical practice, but their efficacy is highly controversial. This study reports on a 7-year-old girl with TEN who did not respond to traditional therapy, such as methylprednisolone combined with gamma globulin, but was finally cured with an additional low-dose etanercept. The results showed that etanercept therapy in paediatric TEN is safe, reliable and worth recommending.Keywords: child toxic epidermal necrolysis, etanercept, glucocorticoids, gamma globulin

It is an independent risk factor for the occurrence and development of metabolic syndrome, type 2 diabetes, hypertension, cardiovascular disease, chronic kidney disease, and gout. The enzyme urate oxidase can metabolize urate to allantoin, resulting in decreased urate concentrations. Pegylated the urate oxidase can extend half-life and decrease immunogenicity of the protein. This trial aims to evaluate the safety, tolerability, pharmacokinetics(PK), pharmacodynamics(PD) and immunogenicity of a new intravenous PEGylated urate oxidase produced by Xiuzheng Bio-Medicine Research Institute Co., Ltd.Methods and Analysis: A randomized, double-blind, placebo-controlled, phase I, dose escalation study will be conducted in China. In total, 56 subjects will be enrolled in the study, with 24 healthy subjects in the low dose-escalation stage and 32 patients with hyperuricemia in the high dose-escalation stage. There is a bridging between the two stages. Subjects are randomized to PEGylated urate oxidase or the placebo in a 3:1 ratio in each group and followed up for 71 days observation. The primary outcomes include PK, PD, tolerability; the secondary outcomes include safety and immunogenicity.Ethics and Dissemination: The trial is performed abiding by the Declaration of Helsinki, Good clinical practice (GCP) and the guidelines of China National Medical Products Administration (NMPA).

We hypothesized that fatty oil nanoparticles (OIL-NPs) could overcome this limitation. The protective effect of OIL-NPs against monocrotaline-induced lung injury in rats was studied.Methods: We prepared OIL-NPs by wrapping fatty oil with polylactic-polyglycolide nanoparticles (PLGA-NPs) and conducted in vivo and in vitro experiments to explore its anti-pulmonary hypertension (PH) effect. In vitro, we induced malignant proliferation of pulmonary artery smooth muscle cells (RPASMC) using anoxic chambers, and studied the effects of OIL-NPs on the malignant proliferation of RPASMC cells and phospholipase C (PLC)/inositol triphosphate receptor (IP3R)/Ca2+ signal pathways. In vivo, we used small animal echocardiography, flow cytometry, immunohistochemistry, western blotting (WB), polymerase chain reaction (PCR) and metabolomics to explore the effects of OIL-NPs on the heart and lung pathological damage and PLC/IP3R/Ca2+ signal pathway of pulmonary hypertension rats.Results: We prepared fatty into OIL-NPs. In vitro, OIL-NPs could improve the mitochondrial function and inhibit the malignant proliferation of RPASMC cells by inhibiting the PLC/IP3R/Ca2+signal pathway. In vivo, OIL-NPs could reduce the pulmonary artery pressure of rats and alleviate the pathological injury and inflammatory reaction of heart and lung by inhibiting the PLC/IP3R/Ca2+ signal pathway.Conclusion: OIL-NPs have anti-pulmonary hypertension effect, and the mechanism may be related to the inhibition of PLC/IP3R/Ca2+signal pathway.

CLI is characterized by microcirculatory dysfunction, muscle tissue necrosis, and inflammation. Patients may suffer from the traumatic pain and the increase of plantar pressure, and foot care for patients with CLI has become the “last mile” to improve their life quality. Traditional shoe insoles often lack individual customization, failing to address the unique anatomical needs and hemodynamic characteristics of patients. The study aims to investigate the effects of this innovative intervention on improving the clinical outcomes, and quality of life in CLI patients.Methods and Analysis: This Critical Limb Ischemia Hemodynamic Insole Study is a randomized controlled study performed to explore the effect of a 3D printing insole on foot care of CLI patients. This study recruitment began on November 1, 2021. Patients with CLI confirmed by clinical symptoms and imaging were recruited as the research objects. Participants will be randomly assigned to either the experimental group, which will receive 3D-printed insoles customized based on their hemodynamics, or the control group, which will receive traditionally manufactured insoles. Both groups were followed up for up to 24 months after surgery, including claudication distance, claudication time, pain score, rehospitalization, etc.Trial Registration Number: ChiCTR2100051857.Keywords: 3D printing, insole, hemodynamics, critical limb ischemia

To foster healthy aging, person-centered integrated care that is responsive to older adults has been proposed by the World Health Organization. The objective of this study was to identify factors that impact the successful implementation of integrated care for older adults with multimorbidity in China.Patients and Methods: From July 2022 to May 2023, 33 healthcare providers and managers involved in the delivery and management of healthcare services for older adults with multimorbidity were recruited from Zhejiang Province, China using purposeful and maximum variation sampling methods. Semi-structured, face-to-face in-depth interviews were conducted by the same interviewer in the participants’ native Chinese language until data saturation was reached. Inductive thematic analysis was used to analyze the data, and then, themes were mapped onto six dimensions using the Rainbow Model of Integrated Care to allow for a comprehensive view of the study’s findings.Results: Eleven themes were generated as facilitators and barriers to integrated care for older adults with multimorbidity in China. These themes include (1) clinical integration: patient-centered care, (2) professional integration: interdisciplinary teams and training, (3) organizational integration: resources and accessibility, (4) system integration: community and funds, incentives, and health insurance, (5) functional integration: electronic health record systems, workforce, and guidelines, and (6) normative integration: shared mission.Conclusion: Guided by the Rainbow Model of Integrated Care, various factors at both micro, meso, and macro levels that impact the implementation of integrated care for older adults with multimorbidity in the Chinese context have been identified in this study. The strategies for future interventions and policies should focus on promoting facilitators and addressing barriers.Keywords: delivery of health care, integrated, aged, older adult, multiple chronic conditions, facilitator, barrier

Healthcare elements that aim to provide coordinated, continuous, and comprehensive services for this population were also identified.Patients and Methods: We applied the methodology framework developed by Arksey and O’Malley to guide the review. The three-step search strategy was used to identify relevant English reviews that focused on adverse healthcare outcomes and barriers encountered by older adults with multimorbidity and other stakeholders regarding the single-disease-focused healthcare systems, as well as those concentrated on healthcare elements that aim to provide coordinated, continuous, and comprehensive services for older adults with multimorbidity. Five electronic databases, including PubMed/Medline, CINAHL, Web of Science Core Collection, Cochrane Library, and Embase, were systematically searched from database inception to February 2022. A standardized table was used to extract data. Thematic analysis was then conducted under the guidance of the Rainbow Model of Integrated Care and the Chronic Care Model.Results: Twenty reviews were included in this study. Therapeutic competitions, high healthcare service utilization, and high healthcare costs were three adverse healthcare outcomes experienced by patients. Both patients and healthcare professionals faced various barriers. Other stakeholders, including informal caregivers, healthcare managers, and policymakers, also perceived several barriers. Numerous healthcare elements were identified that may contribute to optimized services. The elements most frequently mentioned included the implementation of shared decision-making, comprehensive geriatric assessments, and individual care plans.Conclusion: This study conducted a comprehensive overview of the current knowledge related to healthcare for older adults with multimorbidity. In the future, it is necessary to develop more coordinated, continuous, and comprehensive healthcare service delivery models based on the healthcare needs of older adults with multimorbidity and the specific characteristics of different countries.Keywords: multiple chronic conditions, aging, healthcare service delivery, long-term care, review

We aimed to use ML algorithms and the traditional multivariate logistic regression to establish prediction models for BMD decreases in T2DM patients over 50 years of age, and compare the performance of the two methods.Patients and Methods: This cross-sectional study was conducted among 450 patients with T2DM from 1 August 2016 to 31 December 2022. The participants were divided into a normal BMD group and a decreased BMD group. Traditional multivariate logistic regression and six ML algorithms were selected to construct male and female models. Two nomograms were constructed to evaluate the risk of BMD decreases in the male and female T2DM patients, respectively. The ML models with the highest area under the curve (AUC) were compared with the traditional multivariate logistic regression models in terms of discriminant ability and clinical applicability.Results: The optimal ML model was the extreme gradient boost (XGBoost) model. The AUCs of the traditional multivariate logistic regression and the XGBoost models were 0.722 and 0.800 in the male testing dataset, respectively, and 0.876 and 0.880 in the female testing dataset, respectively. The decision curve analysis results suggested that using the XGBoost models to predict the risk of BMD decreases obtained more net benefits compared with the traditional models in both sexes.Conclusion: We preliminarily proved that the XGBoost models outperformed most other ML models in both sexes and achieved higher accuracy than traditional analyses. Due to the limited sample size in the study, it is necessary to validate our findings in larger prospective cohort studies.Keywords: type 2 diabetes mellitus, bone mineral density decrease, prediction model, machine learning, nomogram

However, surgical methods of conversion resection for patients with HCC have not been compared. We aimed to compare LH with OH for HCC after conversion therapy.Methods: We retrospectively reviewed the data of 334 patients who underwent conversion resection between January 2016 and December 2020 at Sun Yat-sen University, China. Propensity score matching (PSM) of patients in a ratio of 1:2 was conducted, and 62 patients and 121 patients who underwent LH and OH, respectively, were matched.Results: The LH and OH groups differed at baseline in terms of ALT (P=0.008), AFP (P=0.042), largest tumor size (P=0.028), macrovascular invasion (P=0.006), BCLC stages (P=0.021), and CNLC stages (P=0.048). The incidences of postoperative complications before and after PSM were lower in the LH group than in the OH group (P=0.007 and 0.003, respectively). There were no significant differences in the overall survival (OS) and recurrence-free survival (RFS) between the two groups (P=0.79 and 0.8, respectively). According to the multivariable Cox regression analyses, the largest tumor size (P< 0.0001) and tumor number (P=0.004) were significant and independent prognostic factors of OS.Conclusion: In our study, we found that LH is technically feasible and safe in patients after conversion therapy. Compared with OH, LH showed similar OS and RFS and was associated with fewer postoperative complications.Keywords: laparoscopic hepatectomy, open hepatectomy, hepatocellular carcinoma, conversion therapy, propensity score matching

Progress in the control of tuberculosis has been undermined by the emergence of multidrug-resistant tuberculosis. The aim of the study is to reveal the trends of research on medications for multidrug-resistant pulmonary tuberculosis (MDR-PTB) through a novel method of bibliometrics that co-occurs specific semantic Medical Subject Headings (MeSH).Methods: PubMed was used to identify the original publications related to medications for MDR-PTB. An R package for text mining of PubMed, pubMR, was adopted to extract data and construct the co-occurrence matrix-specific semantic types. Biclustering analysis of high-frequency MeSH term co-occurrence matrix was performed by gCLUTO. Scientific knowledge maps were constructed by VOSviewer to create overlay visualization and density visualization. Burst detection was performed by CiteSpace to identify the future research hotspots.Results: Two hundred and eight substances (chemical, drug, protein) and 147 diseases related to MDR-PTB were extracted to form a specific semantic co-occurrence matrix. MeSH terms with frequency greater than or equal to six were selected to construct high-frequency co-occurrence matrix (42 × 20) of specific semantic types contains 42 substances and 20 diseases. Biclustering analysis divided the medications for MDR-PTB into five clusters and reflected the characteristics of drug composition. The overlay map indicated the average age gradients of 42 high-frequency drugs. Fifteen top keywords and 37 top terms with the strongest citation bursts were detected.Conclusion: This study evaluated the literatures related to MDR-PTB drug therapy, providing a co-occurrence matrix model based on the specific semantic types and a new attempt for text knowledge mining. Compared with the macro knowledge structure or hot spot analysis, this method may have a wider scope of application and a more in-depth degree of analysis.Keywords: multidrug-resistant tuberculosis, pulmonary tuberculosis, medication trends, specific semantic types, MeSH tree, pubMR

Current single-agent checkpoint therapy has limited effectiveness in TNBC patients. In this study, we developed doxorubicin-loaded platelet decoys (PD@Dox) for chemotherapy and induction of tumor immunogenic cell death (ICD). By combining PD-1 antibody, PD@Dox has the potential to enhance tumor therapy through chemoimmunotherapy in vivo.Methods: Platelet decoys were prepared using 0.1% Triton X-100 and co-incubated with doxorubicin to obtain PD@Dox. Characterization of PDs and PD@Dox was performed using electron microscopy and flow cytometry. We evaluated the properties of PD@Dox to retain platelets through sodium dodecyl sulfate-polyacrylamide gel electrophoresis, flow cytometry, and thromboelastometry. In vitro experiments assessed drug-loading capacity, release kinetics, and the enhanced antitumor activity of PD@Dox. The mechanism of PD@Dox was investigated through cell viability assays, apoptosis assays, Western blot analysis, and immunofluorescence staining. In vivo studies were performed using a TNBC tumor-bearing mouse model to assess the anticancer effects.Results: Electron microscopic observations confirmed that platelet decoys and PD@Dox exhibited a round shape similar to normal platelets. Platelet decoys demonstrated superior drug uptake and loading capacity compared to platelets. Importantly, PD@Dox retained the ability to recognize and bind tumor cells. The released doxorubicin induced ICD, resulting in the release of tumor antigens and damage-related molecular patterns that recruit dendritic cells and activate antitumor immunity. Notably, the combination of PD@Dox and immune checkpoint blockade therapy using PD-1 antibody achieved significant therapeutic efficacy by blocking tumor immune escape and promoting ICD-induced T cell activation.Conclusion: Our results suggest that PD@Dox, in combination with immune checkpoint blockade therapy, holds promise as a potential strategy for TNBC treatment.Keywords: drug delivery, doxorubicin, immunogenic cell death, immune checkpoint blockade therapy

It is known that oxidative stress reduces the expression and activity of histone deacetylase (HDAC)-2 by activating phosphoinositide-3-kinase-δ(PI3Kδ)/Akt pathway, which is a common mechanism. The aim of this study was to investigate whether cryptotanshinone (CPT) can improve corticosteroid sensitivity and to investigate the molecular mechanisms by which this occurs.Patients and Methods: Corticosteroid sensitivity in peripheral blood mononuclear cells (PBMCs) collected from COPD patients, or in human monocytic U937 monocytic cells exposed to cigarette smoke extract (CSE), was quantified as the dexamethasone concentration required to achieve 30% inhibition of tumor necrosis factor-α (TNFα)–induced interleukin 8 (IL-8) production in the presence or absence of cryptotanshinone. PI3K/Akt activity (measured as the relative ratio of phosphorylated Akt at Ser-473 to total Akt) and HDAC2 expression levels were determined by western blotting. HDAC activity was evaluated by a Fluo-Lys HDAC activity assay kit in U937 monocytic cells.Results: Both PBMCs in patients with COPD and U937 cells exposed to CSE were found to be insensitive to dexamethasone, accompanied by increased phosphorylated Akt (pAkt) and decreased HDAC2 protein expression. The pretreatment of cryptotanshinone restored their sensitivity to dexamethasone, and simultaneously downregulated the level of phosphorylated Akt and upregulated the level of HDAC2 protein. Pretreatment with cryptotanshinone or IC87114 reversed the decrease in HDAC activity in CSE-stimulated U937 cells.Conclusion: Cryptotanshinone restores corticosteroid sensitivity induced by oxidative stress via inhibition of PI3Kδ and is a potential treatment for corticosteroid-insensitive diseases such as COPD.Keywords: corticosteroid insensitivity, chronic obstructive pulmonary disease, phosphoinositide-3-kinase-δ, histone deacetylase 2, cryptotanshinone

The Oxford Depression Questionnaire is a validated psychometric instrument for assessing emotional blunting. We aimed to evaluate the reliability and validity of the Chinese version of the ODQ (ODQ) in Chinese patients with mood disorders.Methods: 136 mood disorders patients and 95 healthy control participants were recruited at the First Affiliated Hospital of Zhejiang University, School of Medicine. Patients were assessed using the ODQ, Beck Depression Inventory-II (BDI-II), and Montgomery-Asberg Depression Rating Scale (MADRS). Internal consistency reliability and test-retest reliability were analyzed. Confirmatory factor analysis and correlation analysis were used to evaluate construct and convergent validity.Results: A total of 136 patients with mood disorders and 95 healthy controls participated in this study. Cronbach α values were 0.928 (ODQ-20) and 0.945 (ODQ-26). Test-retest reliability coefficients were 0.798 (ODQ-20) and 0.836 (ODQ-26) (p< 0.05); intraclass correlation coefficient values were 0.777 (ODQ-20) and 0.781 (ODQ-26) (p< 0.01). The score of ODQ was positively correlated with BDI-II and MADRS (r=0.326~0.719, 0.235~0.537, p< 0.01). The differences in the ODQ scores between the patient and control groups were statistically significant.Conclusion: The reliability, structural validity, and criterion validity of the ODQ applied to patients with mood disorders meet the psychometric requirements, and the scale can be used to assess emotional blunting in Chinese patients with mood disorders.Keywords: emotional blunting, Chinese, mood disorder, psychometrics, validation

However, promising molecular-level prognostic marker is still lacking to date.Methods: We systematically evaluated the prognostic potential of immune-related long non-coding RNAs (lncRNAs) in ccRCC. The expressions of lncRNAs were validated in clinical tissues of ccRCC. Functional experiments were performed to investigate the role of lncRNAs in ccRCC.Results: Eight hundred and ninety-three lncRNAs were differentially expressed in ccRCC and compared with normal controls and were screened out using three independent cohorts. Among them, 290 immune-related lncRNAs were identified. We identified a seven-lncRNA signature (LINC01270, FIRRE, RP11-37B2.1, RP11-253I19.3, RP11-438L19.1, RP11-504P24.9, and CTB-41I6.1) associated with the overall survival of late-stage ccRCC patients. Further multivariate Cox analysis using clinical factors as covariates showed that our lncRNA signature was an independent biomarker in training (P < 0.001, Log rank test) and validation cohorts (P = 0.003). The seven lncRNAs were closely related to the major targets (PD-1, PD-L1, and CTLA4) of immune checkpoint blockade drugs, implying that they may have potential value in predicting immunotherapy response. The seven lncRNAs may play an important role in tumor-infiltrating immune cells (eg, T/B cells) and tumor progression through regulating the binding of protein receptors/complexes, as revealed by functional analysis. qRT-PCR showed that LINC01270 was upregulated in ccRCC tissues (n=20) compared with paired normal samples. Functional experiments showed that LINC01270 silencing inhibited the proliferation, invasion, and migration of ccRCC cells.Discussion: In summary, the seven-lncRNA signature has great potential in prognosis for patients with late-stage ccRCC, which could be a novel clinical biomarker. LINC01270 could be a novel therapeutic target of ccRCC.Keywords: long non-coding RNA FIRRE, prognosis, renal cell carcinoma, tumor immune

In this study, we focused on identifying the linking genes of the diagnostic biomarkers and effective therapeutic targets associated with these two diseases.Methods: The transcriptomic datasets of atherosclerosis and type 2 diabetes mellitus were obtained from the GEO database. Differentially expressed genes analysis was performed by R studio software, and differential analysis including functional enrichment, therapeutic small molecular agents prediction, and protein–protein interaction analysis were applied to the common shared differentially expressed genes. Hub genes were identified and further validated using an independent dataset and clinical samples. Furthermore, we measured the expression correlations, immune cell infiltration, and diagnostic capability of the three key genes.Results: We screened out 28 up-regulated and six down-regulated common shared differentially expressed genes. Functional enrichment analysis showed that cytokines and immune activation were involved in the development of these two diseases. Six small molecules with the highest absolute enrichment value were identified. Three critical genes (CD4, PLEK, and THY1) were further validated both in validation sets and clinical samples. The gene correlation analysis showed that CD4 was strongly positively correlated with PLEK, and ROC curves confirmed the good discriminatory capacity of CD4 and PLEK in two diseases.We have established the co-expression network between atherosclerosis lesions progressions and type 2 diabetes mellitus, and identified CD4 and PLEK as key genes in the two diseases, which may facilitate both development of diagnosis and therapeutic strategies.Keywords: small molecular agents, immune infiltration, atherosclerosis, diabetes mellitus, inflammation

But, it should be noted that considerable postoperative pain at the bilateral surgical site was a crucial issue. The safety and efficacy of bilateral thoracic paravertebral block (TPVB) have been reported for postoperative analgesia. But, whether bilateral sequential TPVB can be safely and effectively used in simultaneous bilateral UVATS remains unknown. Therefore, this study aimed to determine the analgesic efficacy and safety of bilateral sequential TPVB after simultaneous bilateral UVATS.Study Design and Methods: In this study, 80 participants scheduled for UVATS will be randomly allocated to the bilateral sequential TPVB group (G2) and the control group (G1). The patient of G2 will be performed bilateral TPVB at 2 time-points: before the start of the first side of pulmonary resection and before the start of the contralateral pulmonary resection. G1 will only receive standard analgesia protocol. The primary outcome is the numeric rating scale score during coughing at 24 h postoperatively. The secondary outcomes include the Prince Henry Pain Score scores, sufentanil consumption, postoperative nausea and vomiting, levels of inflammatory factors, and the Quality of Recovery-40 scores at different time points, as well as chronic pain at postoperative day (POD) 90.Discussion: This is the first prospective trial to determine the safety and effectiveness of ultrasound-guided bilateral sequential TPVB for postoperative analgesia following simultaneous bilateral UVATS. This study also intended to evaluate the effect of this intervention on postoperative quality of recovery and inflammation levels. The final results will provide clinical evidence related to bilateral sequential TPVB, and promote the application of that acting as a more appropriate analgesic method for simultaneous bilateral UVATS.Keywords: thoracic surgery, video-assisted, multiple pulmonary nodules, nerve block, pain measurement

We aimed to explore in-hospital emergency treatment delay and the relation of door-to-needle (DTN) time to ambulance arrivals vs walk-in arrivals.Methods: Data were collected from 1276 Chinese AIS patients admitted to a general, tertiary-level hospital for intravenous thrombolysis. Information on patients’ characteristics and time taken during in-hospital emergency treatment was retrieved from the hospital registry data and medical records. Ambulance arrival was defined as being transported by emergency ambulance services, while walk-in arrival was defined as arriving at hospital by regular vehicle. In-hospital emergency treatment delay occurred when the DTN time exceeded 60 minutes. We performed multivariable logistic regression analysis to explore the association between hospital arrivals (by ambulance vs by walk-in) and treatment delay after adjustment for age, sex, education, marital status, residence, medical insurance, number of symptoms, clinical severity and survival outcome.Results: Over half (53.76%) of patients aged over 60 years. Around one-fifth (20.61%) of patients admitted to hospital through emergency ambulance services, while their counterparts arrived by regular vehicle. Overall, the median time taken from the hospital door to treatment initiation was 86.0 minutes. Patients arrived by ambulance (adjusted odds ratio [aOR] = 1.744, 95% confidence interval [CI] = 1.185– 2.566, p = 0.005), had higher socio-economic status (aOR = 1.821, 95% CI = 1.251– 2.650; p = 0.002), or paid out-of-pocket (aOR = 2.323, 95% CI = 1.764– 3.060; p < 0.001) had an increased likelihood of in-hospital emergency treatment delays.Conclusion: In-hospital emergency treatment delay is common in China, and occurs throughout the entire emergency treatment journey. Having a triage pathway involving hospital arrival by ambulance seems to be more likely to experience in-hospital emergency treatment delay. Further efforts to improve triage pathways may require qualitative evidence on provider- and institutional-level factors associated with in-hospital emergency treatment delay.Keywords: in-hospital emergency treatment, acute ischaemic stroke, treatment delay, hospital arrival, triage pathways

The purpose of this study was to offer evidence for the diagnosis and treatment of NS by revealing the detection of TP DNA and CXCL13 concentration in the cerebrospinal fluid (CSF) of HIV-negative syphilis patients.Patients and Methods: This study included 75 syphilis patients. The frequency of TP invasion into the CSF was detected by nested PCR. ELISA was performed to detect CSF CXCL13 concentrations, and ROC analysis was performed to assess diagnostic accuracy. Sociodemographic data, clinical symptoms, and laboratory indices of patients were collected. CSF CXCL13 levels and clinical characteristics of syphilis patients were investigated retrospectively.Results: The detection rate of CSF DNA of TP by nested PCR was 5.3% and 16.7% in HIV-negative syphilis patients and NS patients, respectively. There was a significant difference between the NS and non-NS groups in terms of neurological symptoms, CSF TPPA, CSF TRUST, CSF nucleated cells, CSF protein, and CSF CXCL13 levels (P< 0.05). ROC curve analysis showed that the AUC for CSF CXCL13 levels was 0.906 (95% CI 0.832– 0.981, P < 0.0001), with an optimal critical value of 57.85 pg/mL and sensitivity and specificity of 88.89% and 78.95%, respectively.Conclusion: Nested PCR can be used as an auxiliary diagnosis of NS, and CSF CXCL13 > 60 pg/mL has high sensitivity and specificity for NS patients and non-NS patients. CXCL13 may be a useful marker to distinguish NS from non-NS syphilis in HIV-negative patients.Keywords: neurosyphilis, Treponema pallidum, cerebrospinal fluid, CXCL13

This study aims to evaluate the predictive value of LDH and develop novel nomograms to predict postoperative recurrence and survival in these patients.Methods: This study retrospectively collected 1560 patients with HBV-related HCC who underwent curative resection from four institutions in China. In total, 924 patients were recruited from our center and randomly divided into the training cohort (n = 616) and internal validation (n = 308) cohorts. Additionally, 636 patients were selected from three other centers as the external validation cohort. The C index of inflammation-based scores was calculated and compared in the training cohort. Novel models were developed according to multivariable Cox regression analysis in the training cohort and validated in the internal and external validation cohorts.Results: LDH showed a higher C-index than other inflammation-based scores for recurrence survival (RFS, 0.60, 95% CI, 0.58– 0.61) and overall survival (OS, 0.65, 95% CI, 0.63– 0.68). The nomograms of RFS and OS were developed based on tumor diameter, macrovascular invasion, AFP, operative hemorrhage, tumor differentiation, tumor number and LDH and achieved a high C-index (0.78, 95% CI, 0.76– 0.79 and 0.81, 95% CI, 0.79– 0.83), which were remarkably higher than the C-indexes of the five conventional HCC staging systems (0.52– 0.62 for RFS and 0.53– 0.67 for OS). The nomograms were validated in the internal validation cohort (0.77 for RFS, 0.78 for OS) and external validation cohort (0.80 for RFS, 0.81 for OS) and performed well-fitted calibration curves.Conclusion: The two nomograms based on inflammatory markers achieved optimal prediction for RFS and OS of patients with HBV-related HCC after hepatectomy.Keywords: hepatocellular carcinoma, hepatectomy, inflammation-based scores, lactate dehydrogenase, nomogram

We aimed to clarify the prognostic value of the inflammation-based scores in intrahepatic cholangiocarcinoma (ICC) patients receiving anti-PD1 therapy.Patients and Methods: A total of 73 patients who received anti-PD-1 therapy from February 2019 to February 2021 were included in the study. Representative inflammation-based prognostic scores, including C-reactive protein (CRP), the platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-CRP ratio (LCR), lymphocyte-to-monocyte ratio (LMR), systemic immune inflammation index (SII), CRP-to-albumin ratio (CAR), prognostic nutritional index (PNI), Glasgow Prognostic Score (GPS), and prognostic index (PI), were assessed for prediction accuracy using Kaplan–Meier survival curves and time-dependent receiver operating characteristic (ROC). All the ten inflammation-based prognostic scores were measured before receiving anti-PD1 therapy.Results: All the ten inflammation-based prognostic scores showed good discriminatory ability in terms of overall survival (OS) (all P < 0.01), the higher the score, the worse the prognosis, while the CRP score was a remarkable independent predictor for OS in multivariate analysis (hazard ratio, 6.032; confidence interval, 2.467– 14.752; P < 0.001). The area under the ROC curve at 6 months, 12 months, 18 months and 24 months consistently demonstrated that the predictive value of the CRP score was superior to other inflammation-based scores.Conclusion: Inflammation-based scores predict the efficacy of anti-PD-1 therapy in patients with ICC and CRP score superior to the other inflammation-based prognostic scores in terms of predictive ability.Keywords: inflammation-based score, intrahepatic cholangiocarcinoma, anti-PD-1 treatment, overall survival, C-reactive protein

The characteristics of pathogenic microorganisms and clinical course of myelosuppressed children with hematological diseases were summarized.Results: Our study included 70 patients (45 males) with a median age of 5 years (range: 0.5 to 13 y). During the study period, there were 96 events of suspected infection. According to comprehensive clinical diagnosis, 73 blood infections, 43 pneumonia and 2 urinary tract infections occurred. The positive rate of mNGS was significantly higher than that of traditional microbial detection (83.3% vs 17.7%). The main pathogens detected by mNGS were Pseudomonas aeruginosa, Acinetobacter, human herpesvirus, Candida and Aspergillus. The average duration of fever was 4.9 days and 11.6 days (P < 0.05), and the average cost of anti-infection treatment was RMB ¥ 28,077 and 39,898 (P < 0.05) among children received mNGS within 48 hours and more than 48 hours after the onset of infection symptoms.Conclusion: mNGS contributes to clinical management of children with infection during myelosuppression, especially among patients with negative traditional microbial detection. Early implementation of mNGS in children with symptoms has a tendency to reduce the time of infection, fever and the cost of treatment.Keywords: metagene, pathogenic microorganism, child, hematology and oncology

However, there is a paucity of research on the relationship between lumbar microinstability and chronic low back pain. The purpose of this article is to assess the preoperative radiographic characteristics of patients and evaluate the effects of lumbar microinstability on patient-reported outcomes among single-level lumbar disc herniation (LDH) patients who underwent PTED.Methods: This study retrospectively reviewed the radiographic characteristics of a consecutive series of 127 patients with low back pain and leg pain caused by single-level LDH underwent PTED from August 2018 to March 2021. They were divided into three groups according to the radiographic parameters: the stable group (Group S), the dysfunctional group (Group D), and the microinstability group (Group M). The visual analogue scale (VAS) scores for leg and low back pain and Oswestry Disability Index (ODI) were evaluated preoperatively and postoperatively. Logistic regression analysis was used to identify independent risk factors for CLBP.Results: Compared with Group D and Group S, Group M had the highest ODI scores (P < 0.01) and VAS scores (low back pain) (P < 0.01) after 1 year, while there were no significant differences in the VAS scores for leg pain at different time points after surgery (P > 0.05). In addition, the logistic regression analysis results regarding CLBP revealed that muscle fatty degeneration on MRI (95% CI, 1.20– 8.51, P = 0.02), and facet tropism (95% CI, 1.39 − 11.37, P = 0.01) may be independent risk factors.Conclusion: Patients with lumbar microinstability may have CLBP after PTED, so patients with lumbar microinstability may need to take internal fixation surgery to solve their symptoms.Keywords: chronic low back pain, PTED, microinstability, risk factor

A few cases have been reported in the literature with extreme invasiveness and a poor prognosis. However, there still have not been accepted criteria for diagnosis and treatment of LCNEC. Here we report an unmarried 37 year-old woman who was diagnosed with LCNEC associated with clear cell carcinoma and the tumor index was manifested with a specific increase of AFP. The case received six courses of etoposide and carboplatin chemotherapy as an adjuvant therapy after primary curative surgery. However, she relapsed within 6 months after surgery and metastasized rapidly to distant organs despite combined chemotherapy of paclitaxel, cisplatin, and bevacizumab, and died 18 months after primary surgery. This is the first reported case of LCNEC manifested with a specific increase of AFP and characteristically metastasized to the spine as recurrence. Reviewing our case as well as previously reported cases, LCNEC present with aggressive malignancy and vulnerable to distant metastasis through a hematogenous approach, we conjectured that adding Bevacizumab in primary chemotherapy may be beneficial to extend disease-free survival. But so far there is no recommendation of this regimen for treatment of LCNEC in current guidelines. Further research is needed to confirm this view so as to find the best treatment of LCNEC and improve the prognosis of these patients.Keywords: large cell neuroendocrine carcinoma, ovarian tumors

Moreover, the effect of NIs on ECMO patients’ mortality is still unclear and inconclusive according to literature data. In this study, we examined the prevalence, risk factors, causative organisms, and effects on outcomes of NIs in ECMO patients.Methods: A total of 79 nonsurgical patients (mean age 53.3± 15.2 year (yr); 66% male) who underwent ECMO between January 2011 and September 2020 were enrolled in this retrospective study. Patients’ demographic and clinical data and ECMO parameters were collected from all patients.Results: Among 79 patients who underwent ECMO for a total of 1253 ECMO days (mean time 15.9± 14.1 d), 42 developed NIs. We observed 30 ventilator-associated pneumonia (VAP), 19 bloodstream infections (BSIs), and 4 urinary tract infections, corresponding to 23.9/1000 ECMO days, 15.2/1000 ECMO days, and 3.2/1000 ECMO days, respectively. ECMO duration (22.0± 16.5 VS 8.9± 5.3 d, P < 0.001), invasive mechanical ventilation (IMV) duration (27.4± 20.5 VS 11.4± 10.1 d, P < 0001), and ICU length of stay (35.9± 22.9 VS 15.7± 9.2 d, P < 0.001) were longer in patients with NIs. The independent risk factors for NIs were ECMO duration (Odds Ratio [OR], 1.414; 95% Confidence Interval [CI], (1.051– 1.238); P = 0.002) and viral pneumonia (OR, 5.788; 95% CI, (1.551– 21.596); P = 0.009). Gram-negative bacteria were the most common causative organisms of NIs; Acinetobacter baumannii (A. baumannii), Klebsiella pneumoniae (K. pneumoniae), and Pseudomonas aeruginosa (P. aeruginosa) were the most common bacteria. BSI (OR, 8.106; 95% CI, (1.384– 47.474); P = 0.02) was an independent predictor for mortality.Conclusion: NIs are common complications in patients during ECMO treatment, especially VAP, followed by BSI. Also, BSI can negatively affect the survival rate.Keywords: extracorporeal membrane oxygenation, healthcare-associated infections, bloodstream infections, risk factors, mortality

Il-12r beta 2 (IL-12Rβ 2) is important for the production of pathogenic Th1 cells. We aimed to explore the association between IL-12Rβ 2 genetic variants and COPD risk among southern Chinese Han population.Methods: We recruited 996 participants to perform an association analysis through SNPStats online software. We used false-positive report probability analysis to detect whether the positive findings were noteworthy. Haploview 4.2 software and SNPStats were used to conduct the haplotype analysis and linkage disequilibrium. Finally, the interaction of SNP-SNP in COPD risk was evaluated by multi-factor dimensionality reduction.Results: The study found evidence that genetic loci in IL-12Rβ 2 (rs2201584, rs1874791, rs6679356, and rs3790567) were potentially associated with the COPD susceptibility. In particular, IL-12Rβ 2-rs2201584 and -rs1874791 showed close associations with COPD risk in both overall and several stratified analyses. Overall analysis or several stratified analyses indicated that allele A or homozygous genotype AA of IL-12Rβ 2-rs2201584 were risk factors for COPD (Allele A: OR (95% CI) = 1.23 (1.02– 1.48), p = 0.033; genotype AA: OR (95% CI) = 1.76 (1.15– 2.69), p = 0.009). The allele A or homozygous genotype AA of IL-12Rβ 2- rs1874791 were also risk factors for COPD (Allele A: OR (95% CI) = 1.36 (1.10– 1.68), p = 0.004; genotype AA: OR (95% CI) = 2.17 (1.18– 3.99), p = 0.013).Conclusion: Intronic variants in IL-12Rβ 2 (rs2201584, rs1874791, rs6679356, and rs3790567) were associated with the COPD susceptibility. In particular, there were sufficient evidences that IL-12Rβ 2-rs2201584 and -rs1874791 were associated with the increasing risk of COPD.Keywords: chronic obstructive pulmonary disease, IL-12Rβ 2, genetic variants, Chinese Han population

Programmed cell death receptor-1 (PD-1) inhibitor has been approved and recommended to treat ≥ 3 line G/GEJ patients. A significant clinical benefit of PD-1 inhibitors in addition to cCRT has been observed in locally advanced lung cancer. Sintilimab, a humanized IgG4 monoclonal antibody with high affinity and specificity for PD-1, has shown promising efficacy with an overall response rate of 85% in combination with chemotherapy in gastric cancer in a phase Ib study (NCT02937116).Patients and Methods: SHARED is a prospective, multicentre, single-arm Phase II trial in China, exploring the efficacy of sintilimab in combination with cCRT in locally advanced G/GEJ adenocarcinoma. According to a Simon optimal two-stage clinical design, 34 patients will be enrolled. All the eligible patients will receive one cycle of induction chemotherapy (S-1 plus nab-PTX) combined with sintilimab, followed by cCRT (radiotherapy plus nab-PTX) combined with sintilimab. Prior to the surgery, patients will receive another cycle of chemotherapy (S-1 plus nab-PTX) combined with sintilimab. In the adjuvant setting, all participants will be treated with 3 cycles of chemotherapy (S-1 plus nab-PTX) combined with sintilimab. The primary endpoint is the rate of pathological complete response (pCR). The secondary endpoints include disease-free survival (DFS), major pathological response (MPR), R0 resection rate, surgical AEs, overall survival (OS), event-free survival (EFS), and safety profile. Moreover, the prognostic value of tumor biomarkers and immune biomarkers will be explored.Conclusion: SHARED is designed to primally evaluate the efficacy and safety of sintilimab in combination with cCRT in locally advanced G/GEJ cancers and to prospectively validate the prognostic value of tumor biomarkers and immune biomarkers.Keywords: anti-PD-1, induction chemotherapy, chemoradiotherapy, immunotherapy

The prognostic effects of factors such as age and laboratory indicators were analyzed using the Kaplan–Meier method and Cox proportional hazards model. A prognostic nomogram model was established to predict the progression of patients with COVID-19.Results: A total of 524 patients in Hunan province with COVID-19 from December 2019 to October 2020 were retrospectively recruited. Among them, 479 eligible patients were randomly assigned into the training cohort (n = 383) and validation cohort (n = 96), at a ratio of 8:2. Sixty-eight (17.8%) and 15 (15.6%) patients developed severe COVID-19 after admission in the training cohort and validation cohort, respectively. The differences in baseline characteristics were not statistically significant between the two cohorts with regard to age, sex, and comorbidities (P > 0.05). Multivariable analyses included age, C-reactive protein, fibrinogen, lactic dehydrogenase, neutrophil-to-lymphocyte ratio, urea, albumin-to-globulin ratio, and eosinophil count as predictive factors for patients with progression to severe COVID-19. A nomogram was constructed with sufficient discriminatory power (C index = 0.81), and proper consistency between the prediction and observation, with an area under the ROC curve of 0.81 and 0.86 in the training and validation cohort, respectively.Conclusion: We proposed a simple nomogram for early detection of patients with non-severe COVID-19 but at high risk of progression to severe COVID-19, which could help optimize clinical care and personalized decision-making therapies.Keywords: nomogram, COVID-19, SARS-CoV-2, C-reactive protein, predictive model

Its compatibility and stability with common clinical drugs such as antibiotics was rarely reported to ensure the children’s safety and the rational use of drugs. The aim of the present study was to investigate physical and chemical stability of pediatric electrolyte supplements injection mixed with ten commonly used clinical drugs.Methods: According to clinical drug concentration, we mix the pediatric electrolyte supplements injection mixed with ten drugs. The compatible solutions were withdrawn at certain time intervals (0, 0.5, 1, 2, 4, 6 hours) after mixing and tested by description, insoluble particles detection, pH determination and high performance liquid chromatography (HPLC) assay of active ingredient as measures of physicochemical compatibility.Results: No obvious appearance changes were observed when mixing. Furthermore, over the 6 hours post-preparation period the pH values were within the requirements of each drug quality standard and the number of insoluble particles (≥ 10 and ≥ 25μm) met requirements of Chinese Pharmacopeia (Edition 2020) except for mezlocillin sodium for injection. The percentages of the initial concentrations maintained at a minimum of 97% in the mixtures within 6 hours.Conclusions: Nine commonly used clinical drugs remained stable in the pediatric electrolyte supplements injection for 6 hours at 25°C and avoiding from light. Mezlocillin sodium for injection was not recommended to be combined with electrolyte supplement injection for children because its insoluble particles exceed the standard.Keywords: compatibility, stability, pediatric electrolyte supplements injection

The age was from fifteen to fifty-seven years. In the course of disease, tumor cells were discovered in cerebrospinal fluid of three patients and in biopsy samples of four patients. Cerebrospinal fluid (CSF) test results showed white blood cell counts increased in seven patients, protein increased in six patients and glucose reduced in five patients. In addition, MRI revealed that the white matter abnormalities showed in all cases and pia mater was enhanced in four patients, meningeal enhanced was observed in three patients. All patients were given appropriate therapy during hospitalization. Follow-up result showed that all patients passed away two to five months after diagnosis.Conclusion: MC causes spinal membrane, spinal nerve root to be involved besides, also can produce the matter of myelopathy. Early detection of intramedullary lesion is conducive to strengthening the awareness of the diagnosis of MC.Keywords: meningeal carcinomatosis, myelopathy, histopathological investigation, CSF cytology
