Objective To systematically evaluate the risk prediction models for anastomotic leakage (AL) in patients with esophageal cancer after surgery. Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

ObjectiveTo investigate the effect of 1，25（OH）₂D₃ on the level of peroxisome proliferator-activated receptor-γ （PPAR-γ） in the liver， the phenotype of hepatic macrophages， and liver inflammation in a rat model of nonalcoholic steatohepatitis （NASH）， as well as the mechanism of 1，25（OH）₂D₃ improving liver inflammation. MethodsAfter 1 week of adaptive feeding， 24 specific pathogen-free Wistar rats were randomly divided into normal group ［choline-supplemented L-amino acid-defined （CSAA） diet］， normal+1，25（OH）₂D₃ group ［CSAA diet+1，25（OH）₂D₃］， model group ［choline-deficient L-amino acid-defined diet （CDAA） diet］， and model+1，25（OH）₂D₃ group ［CDAA diet+1，25（OH）₂D₃］， with 6 rats in each group. The dose of 1，25（OH）₂D₃ was 5 μg/kg for intraperitoneal injection twice a week for 12 weeks. The serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） were measured， liver histopathology was observed， and SAF score was assessed. M1 hepatic macrophages and M2 hepatic macrophages were measured to analyze in the change in the phenotype of hepatic macrophages， and ELISA was used to measure the levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， interleukin-4 （IL-4）， and interleukin-10 （IL-10） in liver tissue， and qPCR was used to measure the mRNA level of PPAR-γ. The two-factor analysis of variance was use for comparison between groups， and the least significant difference t-test was used for further comparison； the Pearson method was used for correlation analysis. ResultsCompared with the normal group， the model rats with CDAA diet-induced NASH had significant increases in the serum levels of AST and ALT （P=0.019 and P<0.001）， the SAF score of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， and the ratio of M1 and M2 hepatic macrophages （P<0.001）， as well as a significant increase in the level of TNF-α （P<0.001） and a significant reduction in the level of IL-4 in liver tissue （P=0.025）. The 1，25（OH）₂D₃ group had significant reductions in the serum levels of ALT （P<0.001）， the SAF score of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， and the ratio of M1 and M2 hepatic macrophages （P=0.001）， the level of IL-1β （P<0.001） and a significant increase in the level of M2 hepatic macrophages （P=0.017）， the level of IL-10 （P=0.039）， the level of IL-4 （P<0.001）， the level of PPAR-γ （P=0.016）. There were significant interactions between CDAA diet-induced NASH model and 1，25（OH）₂D₃ in serum the levels of AST and ALT （P=0.007 and P=0.008）， the SAF scores of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， the level of M2 hepatic macrophages （P=0.008）， the ratio of M1 and M2 of hepatic macrophages （P=0.005）， the level of TNF-α （P<0.001）， the level of IL-10 （P=0.038）， the level of IL-4 （P<0.001） and the level of PPAR-γ （P=0.009）. The correlation analysis showed that PPAR-γ was negatively correlated with the ratio of M1 and M2 hepatic macrophages （r=-0.415， P=0.044） and was positively correlated with M2 hepatic macrophages （r=0.435， P=0.033）， IL-10 （r=0.433， P=0.035）， and IL-4 （r=0.532， P=0.007）. ConclusionThis study shows that 1，25（OH）₂D₃ improves liver inflammation in NASH by activating PPAR-γ to regulate the phenotypic transformation of hepatic macrophages.

Background In the context of the innovation-driven development strategy, occupational groups are facing increasing work pressure, and its impact on sleep quality and mental health deserves attention. Objective To explore potential mediating role of sleep quality between work stress and mental health status among occupational workers, and to provide a scientific basis for improving their mental health status. Methods Cluster sampling was used to select 2000 workers in Urumqi, Xinjiang Uygur Autonomous Region. They were divided into mental and physical worker groups according to their occupational types, and a questionnaire survey was conducted using General Information Survey Forms, Effort Reward Imbalance scale (ERI), Pittsburgh Sleep Quality Index (PSQI), and Symptom Check List-90 (SCL-90). Work stress level, sleep quality, and mental health were assessed and compared between mental and physical workers. Structural equation modelling was used to evaluate the relationship among work stress, sleep quality and mental health of the workers, and to explore the mediating effect of sleep quality. Results A total of 1979 survey questionnaires were collected, with a response rate of 99%, including 1500 (75.8%) mental workers and 479 (24.2%) physical workers. Linear correlations were confirmed between work stress, mental health, and sleep quality. The correlations of work stress with mental health and sleep quality scale scores were positive for both mental and physical workers (r=0.32, 0.31, P<0.01; r=0.25, 0.25, P<0.01), and sleep quality was also positively correlated with mental health (r=0.47, 0.56, P<0.01) . The final modified structural equation model showed that the coefficients of work stress on sleep quality for the mental and physical workers were 0.56 and 0.46 (P<0.001) respectively, and the coefficients of sleep quality on mental health were 0.52 and 0.80 (P<0.001) respectively. Sleep quality mediated the impact of work stress on mental health of the mental and physical workers, with mediating effect values of 0.29 and 0.37 respectively. The adaptability of both structural equation models is less than 3. Conclusion Occupational population's work stress and mental health may be mediated by sleep quality, and measures should be taken to reduce work stress and improve sleep quality and mental health.

Abstract In recent years, the prevention and treatment of eye diseases in children has become one of the worldwide recognized public health issues. Both genetic and environmental factors can influence the development of offspring visual systems, leading to abnormal vision acuity such as refractive errors, strabismus, and nystagmus. With the aim of elucidating the influencing factors and mechanisms of early life adverse exposures on offspring vision outcomes, the article summarizes the research on exposure in early life and visual acuity in offspring from different perspectives, including tobacco exposure during pregnancy, exposure to microelements, gestational diabetes, gestational hypertension, and drug abuse during pregnancy, so as to provide scientific evidence for the development of more effective strategies to prevent and control eye diseases in children and adolescents.

Objective:To analyze the clinical characteristics, imaging, myopathology and outcomes of patients with COVID-19 related autoimmune myopathy.Methods:The clinical features, serum creatine kinase (CK), myositis antibodies, muscle magnetic resonance imaging, myopathology and therapy of 5 patients with COVID-19 related autoimmune myopathy diagnosed in Peking University First Hospital from December 2022 to April 2023 were collected. The effects of the therapy after a short term follow up were analyzed.Results:Among the 5 patients, there were 3 males and 2 females, with onset age of 42-86 years. All patients presented with proximal muscle weakness in the recovery term of COVID-19. Myalgia was noted in 3 cases, dysphagia in 1, skin damage in 2, interstitial lung disease in 1. The serum CK of the 5 patients was 1 663-16 000 IU/L, 1 patient had anti-3-hydroxy-3-methylglutaryl-CoA reductase autoantibodies and 1 patient had anti-signal recognition particle autoantibodies. The electromyography showed myogenic lesions in all patients. Muscle magnetic resonance imaging showed diffuse muscle edema in all patients, myofascial edema in 3 and subcutaneous-tissue edema in 3. The muscle biopsies in 4 patients revealed necrotic myopathy,with high P62 expression in muscle fibers. The electromicroscopy of 2 patients revealed vacuolated mitochondria and intranuclear tubulofilamentous inclusions in muscle fibers. Four patients were treated with glucocorticoids, of whom 2 patients combined with intravenous immunoglobulin, tacrolimus or cyclophosphamide. One case had close monitoring without drug therapy. They showed significant improvement, but the CK was still abnormal in 4 patients.Conclusions:COVID-19 leads to immune mediated myopathy. The manifestation of patients is characterized by proximal predominant weakness and high creatine kinase level. Muscle magnetic resonance imaging shows diffuse muscle edema. The muscle biopsies reveal necrotic myopathy. The effectiveness of immunosuppression needs to be further studied.

Objective Explore changes in polysaccharides in Jiangxiangru before and after ginger juice preparation,and evaluate polysaccharide anti-inflammatory and antioxidant activities before and after processing.Methods The contents of Jiangxiangru polysaccharide(JXRPs)and Ginger juice processed of Jiangxiangru polysaccharide(JZJXRPs)before and after processing were determined by phenol-sulfuric acid method.We used the swelling model in rats and endotoxin(LPS)to establish the RAW264.7 mouse macrophage inflammation model.The optimal administration concentration was determined using a cell proliferation(MTT)assay.Enzyme-linked immunosorbent assay(ELISA)were used to measure Interleukin-6(IL-6),Interleukin-12(IL-12),Nitric oxide(NO),Interleukin-4(IL-4),and Interleukin-10(IL-10).Bleeding time of mice by tail cutting was observed to evaluate the hemostatic effect.The ability to remove 1,1-diphenyl-2-picryl-hydrazyl radical(DPPH)and 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)(ABTS)was used to evaluate in vitro antioxidant activity.Results The contents of JXRPs and JZJXRPs were 13％and 22％,respectively.In swollen rats at 4 h after injection,compared with the model group,200 mg/kg JXRPs and 100 mg/kg JZJXRPs significantly reduced rat swelling(P＜0.05).In vitro anti-inflammation assessment showed that the polysaccharides before and after processing significantly inhibited secretion of IL-6,IL-12,and NO(P＜0.01)and promoted secretion of IL-4 and IL-10(P＜0.01),and also that processing post-effects were stronger.The hemostatic experiment show that,compared with the control group,JXRPs increased hemostasis,but without a significant difference,and no significant difference was found using JZJXRPs,although high doses showed a trend to increase hemostasis.In vitro antioxidant activity showed that JXRPs and JZJXRPs had different scavenging abilities for DPPH and ABTS with IC50 values of JXRPs of 0.2215 and 0.2110 mg/ml,respectively,and IC50 values of JZJXRPs of 0.1651 and 0.1884 mg/mL,respectively.Conclusions After Jiangxiangru is produced in ginger juice,it promotes dissolution of polysaccharides and increases polysaccharide content.Anti-inflammatory,hemostasis,and antioxidant capacities are stronger in JZJXRPS than JXRPS,which lays the foundation for follow-up research and clinical applications of JXRPS.

ObjectiveTo investigate the therapeutic effect of Ganmai Dazao Tang on breast cancer-related depression and explore the mechanism of the decoction in regulating immune inflammation and neurotransmitters via the mitogen-activated protein kinase （MAPK）/nuclear factor-κB （NF-κB） pathway. MethodBALB/c mice were randomized into control， model， fluoxetine （5 mg·kg^-1·d^-1）， and low- and high-dose （crude drug 20 and 40 g·kg^-1， respectively） Ganmai Dazao Tang groups （n=10）. The mouse model of 4T1 orthotopic transplantation-induced breast cancer-related depression-like behavior was established. The depression-like behavior of mice was assessed by the tail suspension test and the forced swimming test. RT-qPCR was employed to determine the mRNA levels of interleukin （IL）-17A， forkhead box P3 （FoxP3），IL-1β， IL-6， and tumor necrosis factor-α （TNF-α） in the cerebral cortex. Flow cytometry was employed to measure the proportions of immune cell subsets in the spleen and thymus. HPLC-MS/MS was employed to measure neurotransmitter levels in the cerebral cortex. Western blotting was employed to detect the activation of the MAPK/NF-κB pathway. ResultCompared with the model group， administration of Ganmai Dazao Tang at a dose of 40 g crude drug·kg^-1 continuously for 4 weeks shortened the immobility time of modeled mice in the tail suspension and forced swimming tests （P<0.05）， down-regulated the mRNA levels of IL-1β， IL-17A， and TNF-α （P<0.05）， increased the proportions of T cells， CD4⁺ T cells， B cells， helper T 17 （Th17） cells， and regulatory T （Treg） cells， and reduced the proportion of CD8⁺ T cells （P<0.05）. Furthermore， it lowered the levels of 5-hydroxyindoleacetic acid （5-HIAA） and kynurenine （Kyn）， decreased the kynurenine/tryptophan （Kyn/Trp） ratio （P<0.05）， increased the content of 5-hydroxytryptamine （5-HT）， and down-regulated the protein levels of phosphorylated extracellular signal-regulated kinase （p-ERK）， phosphorylated p38 MAPK， and phosphorylated nuclear factor-κB p65 （P<0.05）. ConclusionGanmai Dazao Tang can down-regulate the expression of inflammatory cytokines such as IL-1β， IL-17A， and TNF-α， restore 5-HT metabolism and Kyn/Trp balance， increase the 5-HT content， and reduce the activation of p38 MAPK， ERK， and the MAPK-mediated NF-κB signaling pathway to reduce neuroinflammation in the treatment of cancer-related depression.

ObjectiveTo investigate the effects of health distress on depression and anxiety among the middle-aged and elderly hearing-impaired people, and to explore the mediating effect of social capital, so as to provide an evidence for the implementation of appropriate interventions. MethodsA face-to-face self-designed questionnaire survey was conducted on 271 middle-aged and elderly hearing-impaired people aged 50 years and above in Shanghai from September 2021 to February 2022, including the general information of the subjects, social capital scale, hospital anxiety and depression scale, and health distress scale. The higher the total scores of the social capital scale, the higher level of social capital. Higher scores on the hospital anxiety and depression scale indicate more severe anxiety and depression, and scores >7 points were used to define an anxiety or depression status. The higher scores of the health distress scale, the worse the health condition of the respondents. Univariate and multivariate linear regression models were used to investigate the effects of health distress on depression and anxiety, and the mediating effects were used to test the mediating role of social capital between health distress and depression and anxiety. ResultsThe mean scores of depression, anxiety, social capital and health distress among the middle-aged and elderly hearing-impaired people aged 50 years and above were (11.063±5.892), (58.391±15.273) and (6.384±4.787) points, respectively. Health distress scores were positively correlated with social capital scores, health distress was positively correlated with depression and anxiety, while social capital was negatively correlated with depression and anxiety (all P<0.05). Social capital had masking effects on the relationship between health distress, depression and anxiety (all P<0.05), which accounted for 24.11% and 18.93% in the effects of depression and anxiety, respectively. ConclusionThe levels of depression and anxiety are higher among the middle-aged and elderly hearing-impaired people aged 50 years and above, and health distress can affect the levels of depression and anxiety through social capital. Health workers should take measures to reduce health distress and improve social capital among the middle-aged and elderly hearing-impaired people, so as to further alleviate the occurrence and development of depression and anxiety.
