Objective To understand the current status of work-related musculoskeletal disorders (WMSDs) among operating room doctors,thereby analyzing its effect on mental health. Methods A total of 1013 doctors in the operating rooms of 30 hospitals in 24 provinces from September to December 2022 were selected by cross-sectional survey method. The domestic musculoskeletal disease questionnaire was used to investigate the occurrence of WMSDs in operating room doctors,the symptom check list-90 (SCL-90) was used to evaluate the psychological status of operating room doctors,the relationship between WMSDs related items and SCL-90 scores was analyzed,the correla-tion between the rest time of each shift and SCL-90 factors was analyzed by Pearson method,and the influencing factors of mental health of operating room doctors were analyzed by multivariate Logistic regression.Results A total of 1100 questionnaires were distributed and 1013 valid questionnaires were recovered,with an effective rate of 92.10％. The incidence of WMSDs among operating room doctors in the past 1 year was 95.06％. The body parts with incidences of WMSDs from high to low were as follows:waist (36.92％),neck (35.54％),shoulder (33.56％),and upper back (32.77％). In the past 1 year,the SCL-90 scores and total scores of patients with musculoskeletal pain in various body parts,keeping the same back posture for a long time while work,bending the back at the same time of turning frequently while working,bowing the head for a long time while working,and bending the knee for a long time while working were significantly higher than those who were without the above conditions (P<0.05). Shorter rest time of each shift and longer periods of keeping the same back posture were the risk factors for the development of mental illness in operating room doctors. Conclusion The incidence of WMSDs in operating room doctors is high,which can influence the mental health of operating room doctors. Therefore,operating room doctors should avoid keeping the same back posture for a long time,bending the back at the same time of turning frequently,bowing the head for a long time,and bending the knee for a long time while working,and increase the rest time of each shift,in order to improve the mental condition of the operating room doctors.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

We investigated the prevalence and spatial distribution characteristics of T.gondii infection in cats in China,to provide a scientific basis for the prevention and con-trol of T.gondii.We searched PubMed,CNKI,Wanfang Da-tabase,and Baidu Academic Database to retrieve studies on the seroprevalence of T.gondii in domestic cats published by December 31,2023,in China,to investigate the spatial loca-tion and expression of T.gondii infection in China by using Geographical Information Systems(GIS).SPSS 26.0 software was used for statistical analysis.A total of 86 eligible studies published between 1984 and 2023 were included in this study,covering 28 provincial administrative regions and involving 20 722 cats.The ArcGIS classification results indicated that the overall positivity rate of T.gondii in domestic cats was 14.78％(3 080/20 836,95％CI:14.07％-15.03％).No epidemiological study of T.gondii infection in cats has been reported in Tibet,Tianjin,Hainan,Hong Kong,Ma-cao,or Taiwan.The prevalence of T.gondii infection in cats was highest in Shanxi Province(60％,54/90,95％CI:49.82％-70.18％),followed by Hebei Province(57.33％,43/75,95％CI:46.07％-68.59％),Henan Province(45.53％,173/380,95％CI:46.07％-68.59％),and Yunnan Province(43.64％,24/55,95％CI:30.49％-56.79％).The lowest seroprevalence of T.gondii antibody was found in Jiangxi Province(2.47％,2/81,95％CI:-0.90％-5.90％).Furthermore,the seropreva-lence of T.gondii in cats in northern China was 14.12％(2 044/14 491 95％CI:12.34％-15.90％),whereas that in southern China was 16.30％(1 036/6 355 95％CI:15.40％-17.20％).Significant differences were observed between them(x2=16.60,P＜0.05).The temporal distribution results indicated a decrease in the overall seroprevalence of T.gondii in cats in China from 1984 to 2023.Our findings suggested that T.gondii in cats is widespread in China,with a stable epidemic cycle,and the rates of Toxoplasma positivity vary greatly among regions.The increasing prevalence of pet cats in China,and the close rela-tionship between these cats and humans,may pose substantial exposure risks to a large susceptible population.Therefore,the association between cat ownership and T.gondii infection in humans,and how to decrease human environmental contamination through cat exposure to T.gondii and T.gondii oocysts,requires further investigation.

In the process of seeking new strategies to improve the efficacy of antidepressants,traditional Chinese medicine inter-vention has gradually revealed its unique prevention and treat-ment advantages.The dopamine reward system is closely in-volved in the pathological occurrence and development of depres-sion.Currently,research has mostly focused on the functional mechanism of a specific nucleus in the dopamine reward system,and there is less research focused on the functional mechanism of the neural circuit.In the current micro research on reward cir-cuits,the association between abnormal reward circuits and neg-ative emotions such as anxiety and depression has been widely recognized.Traditional Chinese medicine intervention can exert antidepressant effects by influencing reward circuits.This article provides a review on the loop mechanism of dopamine reward system involvement in depression and research on traditional Chinese medicine intervention.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.
