Nlrp3 is a vital integration point of diverse extracellular stimuli and cellular stress. However, inappropriate activation of Nlrp3 results in progression of autoinflammatory and metabolic disorders. Atrazine, using widely in agricultural sector, is a toxic environmental factor for human. Here, this study found that atrazine could induce oxidative stress and the expression of Nfkb and IRF1 in spleen, promoting the ox-mtDNA formation. And production and release of ox-mtDNA stimulated the Nlrp3 inflammasome. Lastly, atrazine induced the pyroptosis in spleen mediating the activation of Nlrp3 inflammasome. Additionally, lycopene, a kind of carotenoid, is natural bioactive component in fruits and vegetables, which is applied towards reducing oxidative stress. It was found that lycopene could ameliorate the pyroptosis induced by atrazine via inhibition of the ox-mtDNA production. The results also provided evidence that lycopene had the potential role in prevention Nlrp3 inflammasome activation by depleting the ox-mtDNA.

Di (2-ethylhexyl) phthalate (DEHP) is an environmentally persistent and bioaccumulative plasticizer. Accumulation of DEHP in the body can eventually cause kidney damage. As a type of natural carotenoid, lycopene (LYC) has a potential protective effect on renal cells, but the protective mechanism has not yet been elucidated. The major goal of this study was to see how effective LYC was at treating DEHP-induced nephrotoxicity in mice. ICR mice were treated with DEHP (500 mg/kg BW/day or 1000 mg/kg BW/day) or LYC (5 mg/kg BW/day) for 28 days. Through histopathology and ultrastructure, we found that LYC attenuated DEHP-induced renal tubular cell and glomerular damage. LYC relieved DEHP-induced kidney injury evidenced by lower levels of blood urea nitrogen (Bun), creatinine (Cre), and uric acid (Uric). Meanwhile, the reduced expression of kidney injury molecule-1 (Kim-1) also supported it. Notably, LYC can alleviate the activity or content of cytochrome P450 system (CYP450s) interfered with by DEHP. In addition, LYC treatment reduced nuclear accumulation of DEHP-induced aromatic hydrocarbon receptor (AhR) and AhR nuclear transporter (Arnt), and its downstream target genes such as cytochrome P450-dependent monooxygenase (CYP) 1A1, 1A2, and 1B1 expression significantly decreased to normal in the LYC treatment group. In summary, LYC can mediate the AhR/Arnt signaling system to prevent kidney toxicity in mice caused by DEHP exposure.

Colorectal carcinoma (CRC) is the second most deadly cancer worldwide. Therapies that take advantage of DNA repair defects have been explored in various tumors but not yet systematically in CRC. Here, we found that Diphosphoinositol Pentakisphosphate Kinase 2 (PPIP5K2), an inositol pyrophosphate kinase, was highly expressed in CRC and associated with a poor prognosis of CRC patients. In vitro and in vivo functional studies demonstrated that PPIP5K2 could promote the proliferation and migration ability of CRC cells independent of its inositol pyrophosphate kinase activity. Mechanically, S1006 dephosphorylation of PPIP5K2 could accelerate its dissociation with 14-3-3 in the cytoplasm, resulting in more nuclear distribution. Moreover, DNA damage treatments such as doxorubicin (DOX) or irradiation (IR) could induce nuclear translocation of PPIP5K2, which subsequently promoted homologous recombination (HR) repair by binding and recruiting RPA70 to the DNA damage site as a novel scaffold protein. Importantly, we verified that S1006 dephosphorylation of PPIP5K2 could significantly enhance the DNA repair ability of CRC cells through a series of DNA repair phenotype assays. In conclusion, PPIP5K2 is critical for enhancing the survival of CRC cells via facilitating DNA HR repair. Our findings revealed an unrecognized biological function and mechanism model of PPIP5K2 dependent on S1006 phosphorylation and provided a potential therapeutic target for CRC patients.

Objective. To systematically evaluate the efficacy and safety of XFZYD for coronary heart disease (CHD). Methods. A comprehensive literature search of randomized controlled trials using XFZYD for CHD was conducted in 10 electronic databases from their establishment to December 20, 2020. The researchers screened the relevant trials in NoteExpress, extracted the data in duplicate independently, assessed the risk of bias in the trials using the Cochrane collaboration tool, and then used Rev Man 5.3 for data analysis. Results. 30 trials with 3126 participants were included for meta-analysis. The results showed that the clinical effects of XFZYD and its combination with chemical drugs (CD) were 1.13 (RR; 1.13; 95% CI, 1.03 to 1.24) and 1.26 (RR; 1.26; 95% CI, 1.20 to 1.32) times those of CD, respectively. And, it could also improve electrocardiogram effect, which was 1.63 (RR; 1.63; 95% CI, 1.04 to 2.53) times that of CD. XFZYD could not only decrease duration of angina pectoris and improve vascular endothelial function but also obviously reduce the TCM syndrome score. When used in combination with CD, it could also lower AF, correct the dyslipidemia, and reduce the blood viscosity. Conclusion. These results demonstrated that XFZYD had great advantages in treating CHD with no obvious adverse reactions. Therefore, it is believed that XFZYD is more suitable for CHD patients with clinical indicators of dyslipidemia, high blood viscosity, or vascular endothelial dysfunction. This study is the first systematic review and meta-analysis with some unique ways, including its comprehensiveness, large-scale search, the novelty of findings, and transparent approach.

Objective We determined the prevalence of sarcopenic obesity in patients with RA using multiple methods and assessed associations with physical functioning. Methods This study evaluated data from three RA cohorts. Whole-body dual-energy absorptiometry (DXA) measures of appendicular lean mass index (ALMI, kg/m2) and fat mass index (FMI) were converted to age, sex and race-specific Z-Scores and categorized using a recently validated method and compared it to a widely-used existing method. The prevalence of body composition abnormalities in RA was compared with two reference populations. In the RA cohorts, associations between body composition and change in the HAQ and the Short Physical Performance Battery (SPPB) in follow-up were assessed using linear and logistic regression, adjusting for age, sex, race and study. Results The prevalence of low lean mass and sarcopenic obesity was higher in patients with RA (14.2; 12.6%, respectively) compared with the reference population cohorts (7–10%; 4–4.5%, respectively, all P Conclusion RA patients had higher rates of low lean mass and sarcopenic obesity than the general population. The recently validated methods characterized body composition changes differently from traditional methods and were more strongly associated with physical function.

PURPOSE: Patients with pneumonia often present to the emergency department and require prompt diagnosis and treatment. Clinical decision support systems for the diagnosis and management of pneumonia are commonly utilized in emergency departments to improve patient care. The purpose of this study is to investigate whether a deep learning model for detecting radiographic pneumonia and pleural effusions can improve functionality of a clinical decision support system for pneumonia management (ePNa) operating in 20 emergency departments. MATERIALS AND METHODS: In this retrospective cohort study, a dataset of 7,434 prior chest radiographic studies from 6,551 emergency department patients was used to develop and validate a deep learning model to identify radiographic pneumonia, pleural effusions, and evidence of multilobar pneumonia. Model performance was evaluated against three radiologists’ adjudicated interpretation and compared to performance of the natural language processing of radiology reports used by ePNa. RESULTS: The deep learning model achieved an area under the receiver operating characteristic curve of 0.833 (95% CI 0.795, 0.868) for detecting radiographic pneumonia, 0.939 (95% CI 0.911, 0.962) for detecting pleural effusions, and 0.847 (95% CI 0.800, 0.890) for identifying multilobar pneumonia. On all three tasks, the model achieved higher agreement with the adjudicated radiologist interpretation compared to ePNa. CONCLUSIONS: A deep learning model demonstrated higher agreement with radiologists than the ePNa clinical decision support system in detecting radiographic pneumonia and related findings. Incorporating deep learning models into pneumonia clinical decision support systems could enhance diagnostic performance and improve pneumonia management.

The volume change and shuttle effect of sulfur are detrimental to the stability and electrochemical performance of the sulfur cathode in lithium–sulfur (Li–S) batteries. In this study, a triple cro...

Larval metamorphosis in bivalves is a key event for the larva-to-juvenile transformation. Previously we have identified a thyroid hormone receptor (TR) gene that is crucial for larvae to acquire “competence” for the metamorphic transition in the mussel Mytilus courscus (Mc). The mechanisms of thyroid signaling in bivalves are still largely unknown. In the present study, we molecularly characterized the full-length of two iodothyronine deiodinase genes (McDx and McDy). Phylogenetic analysis revealed that deiodinases of molluscs (McDy, CgDx and CgDy) and vertebrates (D2 and D3) shared a node representing an immediate common ancestor, which resembled vertebrates D1 and might suggest that McDy acquired specialized function from vertebrates D1. Anti-thyroid compounds, methimazole (MMI) and propylthiouracil (PTU), were used to investigate their effects on larval metamorphosis and juvenile development in M. coruscus. Both MMI and PTU significantly reduced larval metamorphosis in response to the metamorphosis inducer epinephrine. MMI led to shell growth retardation in a concentration-dependent manner in juveniles of M. coruscus after 4 weeks of exposure, whereas PTU had no effect on juvenile growth. It is hypothesized that exposure to MMI and PTU reduced the ability of pediveliger larvae for the metamorphic transition to respond to the inducer. The effect of MMI and PTU on larval metamorphosis and development is most likely through a hormonal signal in the mussel M. coruscus, with the implications for exploring the origins and evolution of metamorphosis.

Type 2 diabetes is a major threat to human health in the 21st century. More than half a billion people may suffer from this pandemic disease in 2030, leading to a huge burden of cardiovascular complications. Recently, 2 novel antidiabetic agents, glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, reduced cardiovascular complications in a number of randomized control trials. To integrate new information and to achieve a streamlined process for better patient care, a working group was appointed by the Taiwan Society of Cardiology to formulate a stepwise consensus pathway for these therapies to reduce cardiovascular events in patients with type 2 diabetes. This consensus pathway is complementary to clinical guidelines, acting as a reference to improve patient care.

It had not been reported that myocardial scar shown on gated myocardial perfusion SPECT (GMPS) might reduce after cardiac resynchronization therapy (CRT). In this study, we aim to investigate the clinical impact and characteristic of scar reduction (SR) after CRT. Sixty-one heart failure patients following standard indication for CRT received twice GMPS as pre- and post-CRT evaluations. The patients with an absolute reduction of scar ≥ 10% after CRT were classified as the SR group while the rest were classified as the non-SR group. The SR group (N = 22, 36%) showed more improvement on LV function (∆LVEF: 18.1 ± 12.4 vs 9.4 ± 9.9 %, P = 0.007, ∆ESV: − 91.6 ± 52.6 vs − 38.1 ± 46.5 mL, P < 0.001) and dyssynchrony (ΔPSD: − 26.19 ± 18.42 vs − 5.8 ± 23.0°, P < 0.001, Δ BW: − 128.7 ± 82.8 vs − 25.2 ± 109.0°, P < 0.001) than non-SR group (N = 39, 64%). Multivariate logistic regression analysis showed baseline QRSd (95% CI 1.019-1.100, P = 0.006) and pre-CRT Reduced Wall Thickening (RWT) (95% CI 1.016-1.173, P = 0.028) were independent predictors for the development of SR. More than one third of patients showed SR after CRT who had more post-CRT improvement on LV function and dyssynchrony than those without SR. Wider QRSd and higher RWT before CRT were related to the development of SR after CRT.

Aims This follow‐up study aimed to examine the 8‐year efficacy and safety of subthalamic nucleus (STN) deep brain stimulation (DBS) for patients with Parkinson's disease (PD) in southern China. Methods The follow‐up data of 10 patients with PD undergoing STN‐DBS were analyzed. Motor symptoms were assessed before and 1, 3, 5, and 8 years after the surgery with stimulation‐on in both off‐medication (off‐med) and on‐medication (on‐med) status using the Unified Parkinson's disease Rating Scale Part III. The quality of life was assessed using the 39‐item Parkinson's Disease Questionnaire. The sleep, cognition, and emotion were evaluated using a series of nonmotor scales. Levodopa equivalent daily dose (LEDD) and stimulation parameters were recorded at each follow‐up. Results The motor symptoms were improved by 50.9%, 37.7%, 36.7%, and 37.3% in 1, 3, 5, and 8 years, respectively, in the off‐med / stimulation‐on status compared with the baseline. The quality of life improved by 39.7% and 56.1% in 1 and 3 years, respectively, but declined to the preoperative level thereafter. The sleep, cognition, and emotion were mostly unchanged. LEDD reduced from 708.1 ± 172.5 mg to 330 ± 207.8 mg in 8 years. The stimulation parameters, including amplitude, pulse width, and frequency, were 2.77 ± 0.49 V, 71.3 ± 12.8 μs, and 121.5 ± 21 Hz, respectively, in 8 years. Conclusion Long‐term therapeutic efficacy of STN‐DBS could be achieved even with relatively low stimulation intensity and medication dosage for PD patients in southern China. Motor improvement and medication reduction were maintained through the 8‐year follow‐up, but improvement in quality of life lasted for only 3 years. No definite changes was found in nonmotor symptoms after STN‐DBS., Long‐term therapeutic efficacy of STN DBS could be achieved even with relatively low stimulation intensity and medication dosage for PD patients in southern China.

Aims Ivabradine has been used in patients who have chronic heart failure (HF) with reduced ejection fraction (HFrEF) and concomitant sinus heart rate ≥70 bpm. This administration for acute HFrEF remains a concern. This study used a real‐world multicentre database to investigate the effects of ivabradine among patients with acute decompensated HFrEF before discharge. Methods and results This study retrospectively identified patients with acute decompensated HFrEF who were administered ivabradine at discharge from two multicentre HF databases. Propensity score matching was performed to adjust for confounders. Cardiovascular mortality, all‐cause mortality, and recurrent HF rehospitalization risks were then compared between those with and without ivabradine treatment. After 1:2 propensity score matching, 876 patients (age, 60.7 ± 14.6 years; female, 23.2%; left ventricular ejection fraction, 28.2% ± 7.8%; and heart rate at discharge, 84.3 ± 13.8 bpm) were included in the final analysis, including 292 and 584 patients with and without ivabradine treatment at discharge, respectively. No significant differences were observed in baseline characteristics between the two groups. At 1 year follow‐up, patients in the ivabradine group had significantly lower heart rates (77.6 ± 14.7 vs. 81.1 ± 16.3 bpm; P = 0.005) and lower HF severity symptoms (New York Heart Association Functional class, 2.1 ± 0.7 vs. 2.3 ± 0.9; P

Background Many lymph nodes resected from early-stage non-small cell lung cancer (NSCLC) patients haven’t metastasis. Selective lymph node dissection (SLND) can reduce surgical trauma by retaining non-metastatic lymph nodes, we aimed to investigate whether SLND could reduce immune impairment compared with systematic lymph node dissection. Methods According to the selection criteria, patients with no metastasis in hilar and regional lymph nodes were selected as the research subjects. The patients were randomly divided into 2 groups: the SLND group (Group SD) and the systematic lymph node dissection group (Group CD). At 24 hours before surgery and on the 1st and 3rd postoperative days (POD), fasting venous blood was sampled to detect cytokine indicators [interleukin-6 (IL-6), C-reactive protein (CRP)], cellular immune indicators [lymphocytes, natural killer cells (NK cells), CD4+, CD8+, CD4+/CD8+], and humoral immune indicators (IgG, IgA, IgM). At the same time, clinically indicators of the patients were recorded. All indicators between the 2 groups were compared. Results The comparison of clinical indicators between the two groups showed that SLND is more conducive to patients’ rapid recovery after surgery. CRP and IL-6 levels in Group CD were significantly higher than those in Group SD after surgery (P0.05). The proportions of CD4+ cells and CD4+/CD8+ in Group CD were significantly lower than those in Group SD at POD1 (P0.05). Conclusions Compared with systematic lymph node dissection, SLND has the following advantages: (I) it is more conducive to patients’ rapid recovery after surgery; (II) it can reduce the body’s acute inflammatory response and non-specific immune damage; (III) it can reduce the damage to cellular immune function caused by surgery.

A better understanding of the clinical features associated with prolonged hospitalization in acute respiratory failure may allow for better-informed care planning.What are the incidence, mortality, cost, and clinical determinants of prolonged hospitalization among patients with acute respiratory failure (ARF)?Using the National Inpatient Sample data from 2004 to 2014, we identified adults 18 years and older with International Classification of Diseases, 9th edition (ICD-9) codes for ARF requiring mechanical ventilation for at least 2 days (ICD-9 518.81 or 518.82, 96.7 or 96.04, and 96.05). Outcomes studied included incidence, in-hospital mortality, cost of hospitalization, and associated patient-level and hospital-level characteristics. Trends were assessed by logistic regression, linear regression, and general linear modeling with Poisson distribution.Of the 5,539,567 patients with ARF, 77,665 (1.4%) had a prolonged length of stay (pLOS), defined as ≥ 60 days. Among those with pLOS, 52,776 (68%) survived to discharge. Over the study period, the incidence of pLOS decreased by 48%, in-patient mortality decreased by 18%, per-patient cost of care rose, but the percentage of the total cost of ARF care consumed by patients with pLOS did not significantly decrease (P = .06). Prolonged LOS was more likely to occur in urban teaching hospitals (OR, 6.8; 95% CI, 4.6-10.2; P .001), hospitals located in the northeastern United States (OR, 3.6; 95% CI, 3.0-4.3; P .001), and among patients with Medicaid insurance coverage (OR, 2.1; 95% CI, 1.9-2.4; P .001).From 2004 to 2014, incidence and mortality decreased among patients with ARF and pLOS, and although per-patient costs rose, the percentage of total cost of care remained stable. There is substantial variation in length of stay for patients with ARF by US region, hospital teaching status, and patient insurance coverage.

OBJECTIVE Rheumatoid arthritis (RA) is associated with low muscle density due to the accumulation of intramuscular fat. The present study was undertaken to identify predictors of changes in muscle density and to determine whether low muscle density predicted changes in strength and physical function. METHODS Patients with RA, ages 18-70 years, completed whole-body dual-energy x-ray absorptiometry and peripheral quantitative computed tomography to quantify lean and fat mass indices and muscle density. Dynamometry was used to measure strength at the hand, knee, and lower leg. Disability and physical function were measured with the Health Assessment Questionnaire (HAQ) and the Short Physical Performance Battery (SPPB). Assessments were performed at baseline and at follow-up. Regression analyses assessed associations between patient characteristics, muscle density, and deteriorations in strength and function. RESULTS Muscle density was assessed at baseline in 107 patients with RA. Seventy-nine of these patients (74%) returned for a follow-up assessment at a median follow-up time of 2.71 years (interquartile range 2.35-3.57). Factors associated with declines in muscle density included female sex, higher disease activity, smoking, and lower insulin-like growth factor 1 (IGF-1) levels. Greater muscle density Z score at baseline (per 1 SD) was associated with less worsening per year according to HAQ, SPPB, and 4-meter walk time scores and a lower risk of a clinically important worsening in HAQ score (odds ratio [OR] 1.90 [95% confidence interval (95% CI) 1.06, 3.42]; P = 0.03) and walking speed (OR 2.87 [95% CI 1.05, 7.89]; P = 0.04). CONCLUSION Worsening of skeletal muscle density occurred in patients with higher disease activity, in smokers, and in those with lower IGF-1. Low muscle density was associated with worsening of physical function. Interventions addressing reductions in muscle quality might prevent functional decline.

We studied the long-term efficacy and safety of cystocele operation by polypropylene mesh. A total of 198 women with stage ≥2 cystocele who had anterior vaginal wall repair with transobturator four-arm polypropylene mesh during 2003 to 2015 were evaluated. Outcomes including clinical characteristics and complications were reviewed by extracting patient data from electronic medical records. In addition, telephone interviews were conducted using a validated questionnaire along with physical examination. The follow-up period was 9.3±0.3 years. The cystocele stage in patients was significantly decreased post-operation compared to that preoperation. The anatomical cure rate for cystocele was 93.4%, and that for stress urinary incontinence was 95%. Comparing the three questionnaires indicated overall average score was improved significantly, except for Female Sexual Function Index Assessment. Early complications were either resolved spontaneously or controlled medically in four cases of hematoma or abscess, three cases of vaginal infection and urinary tract infection, and four cases of difficult micturition. In late complications, four cases of pain were managed, five cases of recurrence were observed and two cases of mesh exposure were treated with ointment and local excision. Transobturator four-arms mesh is an effective and safe method for cystocele repair with low rate of recurrence and complications. We suggest that the use of transobturator four-arm mesh is a still good choice for the old patients with cystocele who are not suitable for general anesthesia and reside in areas where laparoscopy and robots are not available.

Congenital heart disease is exceedingly prevalent in trisomy 13 and 18. Improved survival following congenital heart surgery has been reported, however, mortality remains significantly elevated. Utilizing inpatient data on trisomy 13 and 18 from the 2003-2016 Pediatric Health Information System database, a survival model was developed and validated using data from the California Perinatal Quality Care Collaborative and the California Office of Statewide Health Planning and Development. The study cohort included 1,761 infants with trisomy 13 and 18. Two models predicting survival to 6 months of age were developed and tested. The initial model performed excellently, with a c-statistic of 0.87 and a c-statistic of 0.76 in the validation cohort. After excluding procedures performed on the day of death, the revised model's c-statistic was 0.76. Certain variables, including cardiac surgery, gastrostomy, parenteral nutrition, and mechanical ventilation, are predictive of survival to 6 months of age. This study presents a model, which potentially can inform decision-making regarding congenital heart surgery.

Aims Ivabradine and sacubitril/valsartan are second‐line therapies for patients with heart failure and reduced ejection fraction (HFrEF) based on guideline recommendations. We aimed to evaluate the synergistic effects of these two medications. Methods and results Patients' data were extracted from a multicentre database between 2016 and 2018. Patients were classified into (1) Simultaneous group: simultaneous prescription of ivabradine and sacubitril/valsartan within 6 weeks; (2A) Sequential group, ivabradine‐first: ivabradine was prescribed first, followed by sacubitril/valsartan; and (2B) Sequential group, sacubitril/valsartan‐first: sacubitril/valsartan was prescribed first, followed by ivabradine. A total of 464 patients with HFrEF were enrolled. Cardiovascular death and/or unplanned re‐hospitalizations for HF were less frequent (28.6% vs. 44.8%, P = 0.01), and the improvement of left ventricular ejection fraction (LVEF) was significantly greater in patients from the Simultaneous group than those from the Sequential group (∆LVEF 12.8 ± 12.9% vs. 9.3 ± 12.6%, P = 0.007). Among Sequential subgroups, the ivabradine‐first treatment decreased heart rate and increased systolic blood pressure (SBP) compared with sacubitril/valsartan‐first treatment (∆heart rate −9.1 ± 12.9 b.p.m. vs. 2.6 ± 16.0 b.p.m., P

Deficits in social skills are common in children with Autism Spectrum Disorder (ASD), and there is an urgent need for effective social skills interventions, especially for improving interactions with typically developing peers. This study examined the effects of a naturalistic behavioral social skills intervention in improving social initiations to peers through a randomized controlled trial. Analyses of multimethod, multi-informant measures indicated that children in the active group (SIMI) demonstrated greater improvement in the types of initiations which were systematically prompted and reinforced during treatment (i.e., behavior regulation). Generalization to joint attention and social interaction initiation types, as well as collateral gains in broader social functioning on clinician- and parent-rated standardized measures were also observed.

Lycopene (LYC) is a potent antioxidant synthesized by red vegetables or plants. Di-2-ethylhexyl phthalate (DEHP) is frequently detected in many diverse agricultural environments and considered a reproductive toxicant. The present research was designed to assess the potential mechanisms of DEHP-induced testicular toxicity and the treatment efficacy of LYC. In this study, after oral administration of LYC treatment at the dose of 5mg/kg b.w./day, mice were given 500 or 1000 mg/kg b.w./day of DEHP. This research suggested that LYC prevented DEHP-induced disorder in levels of activity and content of CYP450 enzymes. LYC attenuated DEHP-caused enhancement in nuclear xenobiotic receptors (NXRs) and the phase I metabolizing enzymes (CYP1, CYP2, CYP3, etc.) levels. Furthermore, endoplasmic reticulum (ER) stress was induced by DEHP and triggered unfolded protein response (UPR). Interestingly, LYC could effectively ameliorate these “hit”. The present study suggested that LYC prevents DEHP-induced ER stress in testis via regulating NXRs and UPRER.

Atrazine (ATR), a ubiquitous environmental contaminant in water and soil, causes environmental nephrosis. To reveal the toxic effect of ATR on the kidney and the potential chemical nephroprotective effect of lycopene (LYC), Kun-Ming mice of specific pathogen-free (SPF) grade were treated with LYC (5 mg kg-1) and/or ATR (50 mg kg-1 or 200 mg kg-1) for 21 days. The degree of renal injury was evaluated by measuring the ion concentration, ATPase activities and the mRNA expressions/levels of associated ATPase subunits. In addition, the expression of renal aquaporins (AQPs) was analyzed. The results showed that the renal tubular epithelial cells of ATR-exposed mice were swollen, the glomeruli were significantly atrophied, and the ion concentrations were obviously changed. The activity of Na+-K+-ATPase and the transcription of its subunits were downregulated. The activity of Ca2+-Mg2+-ATPase and the transcription of its subunits were upregulated. The expression of AQPs, especially the critical AQP2, was affected. Notably, ATR-induced nephrotoxicity was significantly improved by LYC supplementation. Therefore, LYC could protect the kidney against ATR-induced nephrotoxicity via maintaining ionic homeostasis, reversing the changes in ATPase activity and controlling the expression of AQPs on the cell membrane. These results suggested that AQP2 was a target of LYC and protected against ATR-induced renal ionic homeostasis disturbance.

Chronic hepatitis B (CHB) has been reported to be associated with impaired prognosis for patients with nasopharyngeal carcinoma (NPC). However, the latent mechanism is unclear. Polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) induce immune suppression in CHB and promote the development of hepatocellular carcinoma. Lectin-type oxidized LDL receptor-1 (LOX-1) was recently identified as a specific marker for PMN-MSDC. We found NPC survivors with CHB had high levels of LOX-1+ PMN-MDSCs. LOX-1+ PMN-MDSCs significantly reduced T cell proliferation and activation. Endoplasmic reticulum stress was induced in LOX-1+ PMN-MDSCs. In addition, LOX-1+ PMN-MDSCs increased their expression of NOX2, a key reactive oxygen species (ROS)-related genes, and levels of ROS illustrated by the DCFDA test. The ROS inhibitor N-acetylcysteine abrogated the suppression of LOX-1+ PMN-MDSCs on T cell activation. The EBV DNA-positivity rate was higher in NPC survivors with CHB than in NPC patients without CHB. Those presenting with positive EBV DNA displayed higher LOX-1+ PMN-MDSC levels. LOX-1+ PMN-MDSCs suppressed the CD8+ T cell response against EBV. This study revealed LOX-1+ PMN-MDSC accumulation and activation in NPC survivors with CHB. LOX-1+ PMN-MDSCs might suppress the host immune response to EBV through ER stress/ROS pathway. These results explained the association of CHB with unfavorable NPC prognosis.

Konjac glucomannan (KGM) is a hypoglycemic polysaccharide with a wide range of molecular weights. But study on hypoglycemic effects of KGMs relate to molecular weight is limited. In this study, KGMs with high and medium molecular weights, and the degraded KGMs were analyzed with physicochemical properties, hypoglycemic effects and mechanisms. Results showed that as the molecular weight KGMs decreased, the viscosity decreased, molecular flexibility increased, while chemical groups, crystal structures and main chains showed little change. KGMs with medium molecular weights (KGM-M1, KGM-M2) showed better effects on increasing body weight, decreasing levels of fasting blood glucose, insulin resistance, total cholesterol and low density lipoprotein cholesterol, and enhancing integrity of pancreas and colon, than KGMs with high or low molecular weights (KGM-H, KGM-L) in type 2 diabetic rats. Mechanism analysis suggested that KGM-M1 and KGM-M2 had higher antioxidant and anti-inflammatory activities on elevating superoxide dismutase, decreasing malondialdehyde and tumor necrosis factor-α levels. Moreover, KGM-M1 and KGM-M2 increased gut microbiota diversity, Bacteroidetes/Firmicutes ratio and Muribaculaceae, decreased Romboutsia and Klebsiella, and improved 6 diabetic related metabolites. Combined, KGM-M1 and KGM-M2 showed higher hypoglycemic effects, due to regulatory activities of antioxidant, anti-inflammatory, intestinal microbiota, and relieved metabolic disorders.

Purpose To further clarify the association between abnormal levels of serum lipid components as the main features of dyslipidaemia and hepatocellular carcinoma, which remains unclear. Patients and Methods We examined the serum level of lipids and apolipoproteins pattern in 471 patients undergoing curative resection for HCC, 193 patients with chronic liver disease, and 104 patients with benign liver diseases. We performed uni- and multivariate analyses to evaluate the predictive roles of lipids and apolipoproteins for recurrence and survival of HCC in a training cohort of 242 patients and then validated in a cohort of 229 patients. Results The majority circulating lipid and apolipoprotein levels such as ApoA1, HDL, and LDL in chronic liver disease and HCC were slightly significantly decreased as compared to those in benign lesion. But no significant differential expression patterns of lipids and apolipoproteins were observed between chronic liver hepatitis and HCC. Multivariable analysis identified ApoA1 as a key parameter related to recurrence and survival in both training and validation cohorts. Moreover, we further demonstrated that low ApoA1 was an independent prognostic factor of poor early recurrence in two cohorts. Conclusion Although the alterations of circulating lipids and apolipoproteins were observed in HCC, none of lipids or apolipoproteins could serve as a diagnostic marker. Serum ApoA1 merits consideration as a novel prognostic marker for patients with HCC undergoing surgery since it predicts early recurrence and survival, especially for early stage patients and may improve the prognostic stratification of patients for clinical management and promote HCC clinic outcomes.

Aim: Cancer-associated fibroblasts (CAFs) are closely related to epithelial-mesenchymal transition (EMT) and chemoresistance in various cancers. Patients & methods: Experiments in vivo and retrospective studies were applied to explore the role of CAFs in epithelial ovarian cancer (EOC). Results: We found that CXCL12 expression was significantly increased in interstitial CAFs by immunofluorescence. CAF-derived CXCL12 induced EMT though CXCR4/Wnt/β-catenin pathway in EOC cells. Inhibited EMT led to increased apoptosis and cisplatin sensitivity. Multivariate regression analysis shows that CXCL12 expression in the stromal cells and cytoreduction satisfaction are independent prognostic markers of platinum-containing chemotherapy sensitivity in 296 EOC patients. Conclusion: CAFs may activate the Wnt/β-catenin pathway in EOC cells via CXCL12/CXCR4 axis, and then induce EMT and cisplatin resistance.

A 56‐year‐old female with manifest Wolff‐Parkinson‐White (WPW) syndrome was sent to emergency room because of preexcited atrial fibrillation (AF) and became sinus rhythm after cardioversion. Then, she received catheter ablation of a left‐sided lateral accessory pathway. The patient immediately developed Wenckebach atrioventricular (AV) block and left bundle branch block (LBBB) during the initial ablation. The ECG still showed LBBB 1 hour after ablation. The LBBB became narrow QRS (The QRS complex in the electrocardiogram. The QRS complex includes the Q wave, R wave, and S wave) 1 day later. Two weeks later, Holter's ECG showed normal sinus rhythm with 1:1 AV conduction even at the maximum heart rate of 125 beats/min. Transient LBBB and poor AV nodal conduction could occur during ablation by the trans‐aortic approach., A 56‐year‐old female with manifest Wolff‐Parkinson‐White (WPW) syndrome was sent to emergency room because of atrial fibrillation with rapid wide QRS tachycardia and became sinus rhythm after cardioversion. After she received catheter ablation of a left‐sided lateral accessory pathway for 1 hour, the ECG showed LBBB, and the LBBB became narrow QRS 1 day later. Eliminating the accessory pathway could recover the AV nodal and His‐Purkinje conduction.

Background. Biomarkers and dual-energy X-ray absorptiometry (DXA) are thought to be poor predictors of bone mineral density (BMD). The Kidney Disease: Improving Global Outcomes guidelines suggest using DXA if the results will affect patient management, but this has not been studied in children or young adults in whom bone mineral accretion continues to 30 years of age. We studied the clinical utility of DXA and serum biomarkers against tibial cortical BMD (CortBMD) measured by peripheral quantitative computed tomography, expressed as Z-score CortBMD, which predicts fracture risk. Methods. This was a cross-sectional multicentre study in 26 patients with CKD4 and 5 and 77 on dialysis. Results. Significant bone pain that hindered activities of daily living was present in 58%, and 10% had at least one low-trauma fracture. CortBMD and cortical mineral content Z-scores were lower in dialysis compared with CKD patients (P = 0.004 and P = 0.02). DXA BMD hip and lumbar spine Z-scores did not correlate with CortBMD or biomarkers. CortBMD was negatively associated with parathyroid hormone (PTH; r = −0.44, P Conclusions. Taken together, routinely used biomarkers, PTH, ALP and Ca, but not DXA, are moderate predictors of cortical BMD. DXA is not clinically useful and should not be routinely performed in children and young adults with CKD 4–5D.

Background Most Parkinson's patients suffered from sleep problems. There is increasing evidence that Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) has a positive effect on several sleep parameters, improving overall sleep quality in patients with PD. However, the results are controversial. Methods We performed a retrospective study and meta-analysis to assess the Parkinson's disease sleep scale (PDSS) in Parkinson's patients. Results We reviewed our data of patients who underwent STN-DBS, and then extracted five other trials to perform a meta-analysis. The pooled results showed an advantage on post-operative PDSS in both our medical center and pooled results (MD = 20.41, 95% CI = [13.03, 27.79], I2 = 61%, P Conclusion In the retrospective study and meta-analysis of 6 trials, we found that DBS can significantly increase sleep quality. Furthermore, motor function improved and Parkinsonian medication was significantly decreased postoperatively. The sample size was enough and no further investigations would change the conclusion.

Di(2-ethylhexyl) phthalate (DEHP) is a widespread pollutant that badly affects animals and human health. Lycopene (LYC) has been used as a dietary supplement that has effective antioxidant and antiobesity functions. The present goal was to understand the molecular mechanisms of LYC preventing DEHP-induced lipid metabolism of the liver. The mice were intragastrically administered with LYC (5 mg/kg) and/or DEHP (500 mg/kg or 1000 mg/kg). Here, we found that LYC attenuated DEHP-caused hepatic histopathological lesions including steatosis. Hematological and biochemical analyses revealed that LYC ameliorated DEHP-caused liver function and lipid metabolism disorders. DEHP caused lipid metabolism disorders via activating the peroxisome proliferator activated receptor α/γ (PPARα/γ) signal transducer and Farnesoid X receptor (FXR)/liver X receptor (LXR) signaling pathway. As a major regulator of lipid metabolism, hypoxia-inducible factor-1α (HIF-1α) system was elevated with increased fatty degeneration under DEHP exposure. However, LYC could decrease the levels of HIF-1α/PPARα/PPARγ/FXR/LXR signaling pathway-related factors. Our research indicated that LYC could prevent DEHP-induced lipid metabolism disorders via inhibiting the HIF-1α-mediated PPARα/PPARγ/FXR/LXR system. This study may provide a possible molecular mechanism for fatty liver induced by DEHP.

Background This study aims to assess the construct validity of a body composition-defined definition of sarcopenic obesity based on low appendicular lean mass relative to fat mass (ALMIFMI ) and high fat mass index (FMI) and to compare with an alternative definition using appendicular lean mass index (ALMI) and percent body fat (%BF). Methods This is a secondary analysis of two cohort studies: the National Health and Examination Survey (NHANES) and the Health, Aging, and Body Composition study (Health ABC). Sarcopenic obesity was defined as low ALMIFMI combined with high FMI and was compared with a widely used definition based on ALMI and %BF cut-points. Body composition Z-scores, self-reported disability, physical functioning, and incident disability were compared across body composition categories using linear and logistic regression and Cox proportional hazards models. Results Among 14, 850 participants from NHANES, patients with sarcopenic obesity defined by low ALMIFMI and high FMI (ALMIFMI -FMI) had above-average FMI Z-scores [mean (standard deviation): 1.00 (0.72)]. In contrast, those with sarcopenic obesity based on low ALMI and high %BF (ALMI-%BF) had below-average FMI Z-scores. A similar pattern was observed for 2846 participants from Health ABC. Participants with sarcopenic obesity based on ALMIFMI -FMI had a greater number of disabilities, worse physical function, and a greater risk of incident disability compared with those defined based on ALMI-%BF. Conclusions Body composition-defined measures of sarcopenic obesity defined as excess adiposity and lower-than-expected ALMI relative to FMI are associated with functional deficits and incident disability and overcome the limitations of using %BF in estimating obesity in this context.

Icariside II (ICAII) is a bioflavonoid compound which has demonstrated anti‑oxidative, anti‑inflammatory and anti‑apoptotic biological activities. However, to the best of our knowledge, whether ICAII can alleviate myocardial ischemia and reperfusion injury (MIRI) remains unknown. The aim of the present study was to determine whether ICAII exerted a protective effect on MIRI and to investigate the potential underlying mechanism of action. A rat MIRI model was established by ligation of the left anterior descending coronary artery for 30 min, followed by a 24 h reperfusion. Pretreatment with ICAII with or without a PI3K/AKT inhibitor was administered at the beginning of reperfusion. Morphological and histological analyses were detected using hematoxylin and eosin staining; the infarct size was measured using Evans blue and 2,3,5‑triphenyltetrazolium chloride staining; and plasma levels of lactate dehydrogenase (LDH) and creatine kinase‑myocardial band (CK‑MB) were analyzed using commercialized assay kits. In addition, the cardiac function was evaluated by echocardiography and the levels of cardiomyocyte apoptosis were determined using a TUNEL staining. The protein expression levels of Bax, Bcl‑2, cleaved caspase‑3, interleukin‑6, tumor necrosis factor‑α, PI3K, phosphorylated (p)‑PI3K, AKT and p‑AKT were analyzed using western blotting analysis. ICAII significantly reduced the infarct size, decreased the release of LDH and CK‑MB and improved the cardiac function induced by IR injury. Moreover, ICAII pretreatment significantly inhibited myocardial apoptosis and the inflammatory response. ICAII also upregulated the expression levels of p‑PI3K and p‑AKT. However, the protective effects of ICAII were abolished by an inhibitor (LY294002) of the PI3K/AKT signaling pathway. In conclusion, the findings of the present study suggested that ICAII may mitigate MIRI by activating the PI3K/AKT signaling pathway.

BACKGROUND Ileocecal intussusception caused by two different tumors is rare, according to a literature review. We describe a case of a male patient with a cauliflower-like mass in the middle of the transverse colon observed by colonoscopy before surgery. It was considered to be intussusception caused by colon cancer. However, a substantial lipomatous mass was seen in the distal end of the intussusception by computed tomography before surgery, which posed a challenge in the preoperative diagnosis. CASE SUMMARY We report a 72-year-old male patient with intussusception. The patient underwent right hemicolectomy and cholecystectomy in our hospital on April 29, 2019. During operation, the ileum was inserted into the ascending colon by about 15 cm, and a tumor with a diameter of approximately 3.0 cm was observed in the distal part of the intestine. An atypical liposarcoma/highly differentiated liposarcoma in the adipose tissue was suspected in the postoperative pathology, and a lipoma was diagnosed after MDM2 gene testing. A 4.0 cm × 5.0 cm polypoid mass was seen immediately adjacent to the mass, and the postoperative pathology report suggested a high-level tubular adenoma. The patient was eventually cured and discharged with an uneventful follow-up. CONCLUSION Intussusception caused by two different types of masses is extremely rare. At present, surgery is the best treatment once intussusception is diagnosed.

Hepatic stellate cells (HSCs) play vital roles in tumorigenesis and progression of hepatocellular carcinoma (HCC). However, there remains a lack of high-throughput studies on gene expression alterations in HCC cells in response to direct interactions with HSCs. In this study, we established a direct co-culture model of HSCs and HCC cells. We found that the expression of a set of miRNAs, most notably miR-1246, was triggered by HSCs. RORα was confirmed as the target gene of miR-1246. Either overexpression of miR-1246 or knockdown of RORα enhanced the proliferation, invasiveness, and metastatic capability of HCC both in vitro and in vivo, through Wnt/β-catenin pathway activation and promotion of epithelial-mesenchymal transition (EMT). Moreover, upregulation of miR-1246 and repression of RORα were prominent features of aggressive clinical HCC. The miR-1246-RORα-Wnt/β-catenin axis is a novel pathway through which HSCs accelerate HCC progression.

BACKGROUND AND AIM Open surgery remains the major approach to treat hepatocellular carcinoma, and laparoscopy-assisted liver resection has been recommended as a superior treatment. However, the efficacy of laparoscopic surgery versus open surgery for cirrhotic patients is under debate. Therefore, the aim of this meta-analysis was to compare the clinical outcomes of laparoscopic and open resection of hepatocellular carcinoma in patients with cirrhosis. METHODS Electronic databases were searched for eligible literature updated on November 2018. After rigorous review of quality, the data were extracted from eligible trials. All the data were pooled with the corresponding 95% confidence interval using RevMan software. Sensitivity analyses and heterogeneity were quantitatively evaluated. RESULTS Fourteen trials met the inclusion criteria. According to the pooled result of surgery duration, laparoscopic surgery was associated with significantly shorter hospital stay [STD mean difference (SMD) = -0.61, 95% confidence interval -0.89 to -0.32; P < 0.0001], lower intraoperative blood loss (SMD = -0.56, 95% confidence interval -0.99 to -0.12; P = 0.01), fewer complications (odds ratio = 0.38, 95% confidence interval 0.28 to 0.52; P < 0.00001) and lower transfusion rate (odds ratio = 0.58, 95% confidence interval 0.36-0.93; P = 0.02). Nevertheless, there was no remarkable difference in operative time (SMD = 0.17, 95% confidence interval -0.25 to -0.59; P = 0.42) between the two groups. The pooled analysis of overall survival showed that laparoscopic surgery did not achieve benefit compared with open surgery (P = 0.02). Moreover, the pooled results of three subgroups indicated that laparoscopic surgery was associated with significantly better disease-free survival (P < 0.05). CONCLUSION The current analysis indicates that laparoscopic liver resection for hepatocellular carcinoma improved intraoperative and disease-free survival, with similar overall survival compared to the open procedure. Laparoscopic surgery may serve as a safe and feasible alternative for selected hepatocellular carcinoma patients with cirrhosis.

Di(2-ethylhexyl)phthalate (DEHP) is widely used as a plasticizer to improve product flexibility and workability. Lycopene (LYC) is a natural compound and has promising preventive potentials, especially antireproductive toxicity, but the specific underlying mechanism is yet to be fully defined. Our study investigated the effect of LYC on DEHP-induced spermatogenesis disorders. Male ICR mice were treated with DEHP (500 or 1000 mg/kg BW/day) and/or LYC (5 mg/kg BW/day) for 28 days. Our results indicated that LYC could relieve the DEHP-induced injury of seminiferous tubules and spermatogenic cells, swelling of endoplasmic reticulum (ER), and an increase of mitochondria. LYC prevented increased levels of nuclear damage to DNA and the deformity rate and decreased values of sperm motility, number, and density. Moreover, LYC treatment decreased DEHP-induced nuclear accumulation of aryl hydrocarbon receptor (AHR) and AHR nuclear translocator (ARNT), and the expressions of their downstream target genes such as cytochrome P450-dependent monooxygenases (CYP) 1A1, 1A2, and 1B1 were markedly reduced to normal in the LYC treatment group. Our study showed that LYC can prevent DEHP-induced spermatogenic disorders via an AHR/ARNT signaling system. This study provided new evidence of AHR as a target for LYC, which can prevent DEHP-induced toxicity.

Background Epidemiological and experimental studies suggest that preeclampsia has a negative impact on maternity and offspring health. Previous studies report that dysregulation in utero-environment increases risk for elderly disease such as cardiovascular disease. However, the underlying mechanisms remain elusive. Specific microRNAs (miRNAs) are packaged in exosomes may regulate microvascular dysfunction in offspring of mothers with preeclampsia. The present study aimed to identify the differential expression profiles of microRNAs in the serum exosomes between patients with preeclampsia and normal pregnancies. Methods A comprehensive miRNA sequence-based approach was performed to compare exosomes carry miRNAs (Exo-miRNAs) expression levels in umbilical serum between normal and preeclampsia patients. Exosomes were isolated using the ExoQuick precipitation kit. Serum exosomes were then viewed under electron microscopy, and their characteristics determined by western blotting and nanoparticle-tracking analysis. Illumina platform was used to perform sequencing. Bioinformatics analysis was used to explore differentially expressed Exo-miRNAs in umbilical serum. Results Based on sequence similarity, 1733 known miRNAs were retrieved. Furthermore, 157 mature miRNAs in serum exosomes were significantly differential expressed between PE and those control groups (P2|FC| > 1). Out, of the 157 miRNAs, 96 were upregulated miRNAs whereas 61 miRNAs were downregulated. The 157 differentially expressed miRNAs targeted 51,424 differentially expressed genes. Functional analysis through KEGG pathway and Gene Ontology results uncovered that target genes of miRNAs with differential expression were significantly linked to several pathways and biological processes. Conclusion The findings of this study showed differential expression of umbilical serum Exo-miRNAs in normal compared with PE patients, implying that these Exo-miRNAs may associate with microvascular dysfunction in offspring of mothers with preeclampsia.

Objective Hereditary spastic paraplegia (HSP) due to ERLIN2 gene mutations was designated as spastic paraplegia 18 (SPG18). To date, SPG18 families/cases are still rarely reported. All early reported cases shared the autosomal recessive (AR) inheritance pattern. Over the past 3 years, autosomal dominant (AD) or sporadic SPG18 cases had been continuously reported. Here, we reported the clinical and genetic features of the first autosomal dominant SPG18 pedigree in Chinese. Methods We conducted detailed medical history inquiry, neurological examinations of the proband and his family members, and charted the family tree. The proband underwent brain and cervical magnetic resonance imaging (MRI), electromyography (EMG), and whole exome sequencing. Sanger sequencing was performed to verify the genetic variation in the proband and some family members. A literature review of all reported SPG18 families/cases was carried out to summarize the clinical‐genetic characteristics of SPG18 under different inheritance patterns. Results Four patients were clinically diagnosed as chronic spastic paraplegia in three consecutive generations with the autosomal dominant inheritance model. All the patients presented juvenile‐adolescent onset and gradually worsening pure HSP phenotype. Clinical phenotypes were consistent within the family. Whole exome sequencing in the proband identified a previously reported heterozygous c.502G > A (p.V168M) mutation in exon 8 of ERLIN2 gene. This mutation was cosegregated with the phenotype in the family and was classified as likely pathogenic according to American College of Medical Genetics and Genomics (ACMG) guidelines. To date, eight AR‐SPG18 families, five AD‐SPG18 families, and three sporadic cases had been reported. Clinical phenotype of AD‐SPG18 was juvenile‐adolescent onset pure HSP, while the phenotype of AR‐SPG18 was mostly complicated HSP with earlier onset and more severe conditions. In rare cases, the initial spastic paraplegia could evolve to rapidly progressive amyotrophic lateral sclerosis (ALS). Conclusions We reported the first autosomal dominant SPG18 pedigree in Chinese Han population, which added more pathogenic evidence for V168M mutation. As more SPG18 cases reported, the essentials of SPG18 need to be updated in clinical practice. Special attentions should be given in gene test for upper motor neuron disorders in case of missing heterozygous mutations in ERLIN2., we reported the first autosomal dominant SPG18 pedigree in Chinese Han population, which added more pathogenic evidence for V168M mutation. The clinical phenotypes of SPG18 are expanded and are highly heterogeneous under different inheritance patterns. As more cases reported, the essentials of SPG18 need to be updated in clinical practice and genetic testing. Special attentions should be given in genetic testing of upper motor neuron disorders in case of missing heterozygous mutations in ERLIN2.

Background The urine protein/creatinine ratio (UPCR) is commonly used in current clinical practice. However, there are only few published clinical data on UPCR from large cohorts of Chinese adults. This study aimed to determine the overall and age‐ and sex‐specific UPCR reference values for healthy Dalian adults. Methods According to the Clinical & Laboratory Standards Institute EP28‐A3c guidelines, 1321 healthy Dalian adults (646 men and 675 women) aged 20–69 years were enrolled. Urine protein and creatinine levels were analyzed in the random morning spot urine samples, and UPCR was calculated. The 95th percentile of the UPCR was used as the normal upper limit. The Mann–Whitney U test was used to test differences among groups. Results The UPCR reference value was 141.7 mg/g for the entire cohort, 128.7 mg/g for men, and 150.8 mg/g for women. In addition, women had relatively higher UPCR values than men in the same age group. We also compared the UPCR reference values between different estimated glomerular filtration rate (eGFR) groups and found that women had significantly higher UPCR values than men in the normal eGFR groups. Conclusions This study provides the overall and age‐ and sex‐specific UPCR reference values for healthy Dalian adults., The urine protein/creatinine ratio (UPCR) reference value was 141.7 mg/g for the entire cohort, 128.7 mg/g for men, and 150.8 mg/g for women. In addition, women had relatively higher UPCR values than men in the same age group.
