Background Neck-related work-related musculoskeletal disorders (WMSDs) are a major type of musculoskeletal disorders with a relatively high proportion. Shanghai has a large number of occupational populations; however, the occurrence of WMSDs at neck among the occupational populations across industries in this city has not been reported, and needs to be addressed. Objective To understand the occurrence of neck-related WMSDs and their influencing factors among occupational populations in 8 industries in Shanghai, and to provide a scientific basis for the prevention and control of WMSDs in this population. Methods From February 2024 to February 2025, a cross-sectional survey employed stratified cluster sampling to select 7829 employed workers from 48 enterprises across 8 industries in Shanghai. The study investigated the occurrence of neck-related WMSDs among the participants over the preceding 12 months. Logistic regression analysis was employed to examine the relationships between WMSDs and various occupational factors. Results A total of 7770 questionnaires were collected, yielding an effective response rate of 99.2%. Overall, the positive rate of neck-related WMSDs among the participants was 11.89% (924/7770). Among different industries, the environmental sanitation industry (19.48%), pharmaceutical manufacturing industry (14.57%), and cigarette manufacturing industry (13.66%) had higher prevalence of neck-related WMSDs. Univariate analysis showed that the risk of neck-related WMSDs was higher in the following groups: those with a job tenure ≥5 years in the current position (OR=1.50–1.70), females (OR=1.77), those with higher education levels (master’s degree or above, OR=2.27), and those with worse self-rated health (very poor health, OR=4.38) (P＜0.05). Multivariate logistic regression analysis identified the following independent risk factors for neck WMSDs: environmental sanitation industry (OR=7.30, 95%CI: 4.72, 11.87), higher educational attainment (master’s degree or above: OR=2.16, 95%CI: 1.36, 3.35), worse self-rated health status (very poor: OR=1.95, 95%CI: 1.31, 2.85), work performed in a single workshop (OR=1.36, 95%CI: 1.13, 1.64), understaffing (OR=1.46, 95%CI: 1.25, 1.70), slight neck forward flexion (OR=1.64, 95%CI: 1.32, 2.06), severe neck forward flexion (OR=2.55, 95%CI: 1.97, 3.30), and maintaining a fixed neck posture for a prolonged period (OR=2.28, 95%CI: 1.93, 2.70). Conversely, work rotation (OR=0.75, 95%CI: 0.65, 0.87), adequate rest (OR=0.70, 95%CI: 0.60, 0.82), and severe back flexion (OR=0.63, 95%CI: 0.46, 0.85) were protective factors against neck-related WMSDs. For the nomogram, the area under the curve (AUC)=0.75 (95%CI: 0.74, 0.77), Hosmer-Lemeshow test P=0.764, and Brier score=0.094, indicating that the model had good discrimination and calibration. Conclusion Among the occupational populations in Shanghai, the environmental sanitation industry, pharmaceutical manufacturing industry, and cigarette manufacturing industry are identified as high-risk industries for neck-related WMSDs. Industry affiliation, educational level, work organization patterns, and awkward neck working postures are confirmed as the core influencing factors for the development of neck-related WMSDs. Targeted and comprehensive intervention measures should be formulated focusing on the aforementioned high-risk industries and key influencing factors. Multi-dimensional collaborative efforts, including ergonomic optimization, improvement of labor management systems, and strengthened health education and promotion, should be implemented to effectively control the risk of neck-related WMSDs in the occupational population, and to provide robust statistical evidence for the advancement of regional occupational health prevention and control strategies.

Objective: To analyze the disease burden of chronic obstructive pulmonary disease (COPD) and changes in its risk factors among residents in Zhejiang Province from 1990 to 2021, so as to identify key priorities for COPD prevention and control. Methods: Data on COPD mortality and disability-adjusted life years (DALY) for residents in Zhejiang Province from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Standardized mortality and standardized DALY rate were calculated using the GBD 2021 world population standard structure. Premature mortality was computed via the life table method. The average annual percent change (AAPC) was applied to analyze trends in COPD mortality, DALY rate, and premature mortality. Changes in deaths of COPD risk factors were evaluated using population attributable fraction (PAF). Results: From 1990 to 2021, the standardized COPD mortality in Zhejiang Province decreased from 272.40/100 000 to 70.56/100 000 (AAPC=-4.395%), and the standardized DALY rate declined from 4 167.37/100 000 to 1 071.89/100 000 (AAPC=-4.396%). Similar downward trends were observed in both males (AAPC=-3.933%, -4.173%) and females (AAPC=-4.785%, -4.480%), all P<0.05. Crude mortality and DALY rates increased with age, and the crude mortality and DALY rates of various age groups in Zhejiang Province showed decreasing trends from 1990 to 2021 (all P<0.05). The premature mortality declined from 4.37% to 0.60% from 1990 to 2021 (AAPC=- 6.206%), with consistent trends across males and females (AAPC=- 6.144%, - 6.379%, all P<0.05). From 1990 to 2021, particulate matter pollution showed the largest reduction in PAF (- 56.76%), while ambient ozone pollution had the largest increase (103.07%) in Zhejiang Province. By 2021, smoking became the leading risk factor for deaths of COPD (PAF=43.32%). Conclusions The standardized mortality, standardized DALY rate, and premature mortality for COPD show consistent declining trends in Zhejiang Province from 1990 to 2021. However, risk factors such as smoking and ambient ozone pollution require intensified focus to further reduce disease burden of COPD.

Objective:To investigate the effects of intraoperative administration of esketamine on gastrointestinal function in patients undergoing laparoscopic total hysterectomy.Methods:A total of 150 patients undergoing laparoscopic total hysterectomy in Dingzhou People’s Hospital from Nov. 2022 to Nov. 2023 were selected as the study subjects. They were divided into the observation group ( n=75) and the control group ( n=75) based on whether esketamine was administered intraoperatively. Patients in the control group received intravenous infusion of normal saline, while those in the observation group received intravenous infusion with added esketamine. Surgical-related time courses, drug dosages, changes in heart rate (HR) , changes in mean arterial pressure (MAP) , serum intestinal fatty acid-binding protein (I-FABP) concentrations at different time points, claudin-1 concentrations at different time points, and postoperative gastrointestinal symptom rating scale scores were observed in both groups. Results:The pneumoperitoneum duration and intraoperative drug dosage were lower in the observation group than in the control group ( P<0.01) . Statistically significant differences were found between groups, time points, and interactions for HR ( P<0.001) , with HR at T2, T3, T4, and T5 being significantly lower in the observation group than in the control group ( P<0.05) . Statistically significant differences were also found between groups, time points, and interactions for MAP changes ( P<0.001) , with MAP changes at T2, T3, T4, and T5 being significantly lower in the observation group than in the control group ( P<0.05) . Statistically significant differences were observed between groups, time points, and interactions for serum I-FABP concentrations at different time points ( P<0.001) , with the serum I-FABP concentrations at 2 hours during pneumoperitoneum and after pneumoperitoneum being significantly lower in the observation group than in the control group ( P<0.05) . Similarly, statistically significant differences were found between groups, time points, and interactions for claudin-1 concentrations at different time points ( P<0.001) , with the claudin-1 concentrations at 2 hours during pneumoperitoneum and after pneumoperitoneum being significantly lower in the observation group than in the control group ( P<0.05) . The gastrointestinal symptom score was lower in the observation group than in the control group, and the time to first flatus and first defecation was shorter in the observation group ( P<0.05) . Conclusion:The intraoperative administration of esketamine in laparoscopic total hysterectomy can promote postoperative gastrointestinal function recovery, reduce gastrointestinal symptom scores, and shorten the time to first flatus and first defecation.

Objective:To explore the expression of lamin (LMN) gene in Colorectal cancer (CRC) , as well as the effects of knockdown LMNA expression in colorectal cancer cells on its migration ability and related molecular mechanisms.Methods:Paraffin-embedded specimens of tumor tissues and corresponding peritumoral tissues were collected from 37 colorectal cancer patients for the detection of LMNA protein expression. Colorectal cancer cell line SW480 was cultured in vitro and divided into Mock group (transfected MOCk-siRNA) and LMNA group (transfected LMNA-siRNA) . Real-time quantitative PCR was used to detect the LMNA mRNA content in SW480 cells of experimental group and control group. The expression levels of LMNA, Wnt and β-catenin in SW480 cells of experimental group and control group were detected by Western blotting. The migration ability of cells in each group was detected by cell scratch test. The migration ability of cells in each group were detected by transwell assay.Results:Immunohistochemical test showed that the positive rate of LMNA protein in colorectal cancer tissues was 89.19% (33/37 cases) , and the expression rate in corresponding paracancer tissues was 48.65% (18/37 cases) . The expression level of LMNA in colorectal cancer tissues was significantly higher than that in paracancer tissues ( P<0.001) . siRNA decreased the expression of LMNA protein in colorectal cancer cells SW480. The scratch healing rate was (53.71±5.34) % in the experimental group and (83.84±6.98) % in the control group. The results of Transwell experiment showed that the number of successfully migrated cells in the experimental group was 34.92±5.11, and that in the control group was 93.87±12.57. The results showed that the migration ability of SW480 cells was significantly decreased after low expression of LMNA ( P<0.01) . Western blot results showed that the relative expression level of Wnt and β-catenin in LMNA group was 0.42±0.12 and 0.22±0.11 respectively. The relative expression levels of Wnt and β-catenin in MOCK group were 1.28±0.26 and 1.14±0.21 respectively. The expression levels of P16 and Wnt and β-catenin in PC3 cells with low LMNA expression were increased ( P<0.05) , while the expressions of WNT and β-catenin were decreased (both P<0.05) . Conclusion:The expression of LMNA was significantly increased in colorectal cancer, which may be related to the malignant degree of colorectal cancer. LMNA proteins may affect the migration ability of colorectal cancer cells by regulating the Wnt/β-catenin signaling pathway.

Objective:To explore the relationship between medical students'family function and anxiety/depression,and the mediating role of loneliness in this relationship.Methods:A total of 577 medical students were surveyed using stratified cluster sampling.Questionnaires assessed family function,loneliness,anxiety,and depression.Spearman correlation analysis was used to examine the relationships among family function,loneliness,anxiety,and depression.The mediating effects were tested using SPSS 26.0 PROCESS program model 4.Results:Medical students'family function,loneliness,anxiety,and depression scores were 8.00(5.00,10.00),16.00(12.00,19.00),3.00(2.00,4.00),and 3.00(2.00,4.00),respectively.Spearman correlation analysis showed that family function was negatively correlated with loneliness(r=-0.337),anxiety(r=-0.237),and depression(r=-0.257)(all P＜0.01).Loneliness was positively correlated with anxiety(r=0.394)and depression(r=0.392)(both P＜0.01).Anxiety was positively correlated with depression(r=0.746,P＜0.01).Family function negatively predicted anxiety(β=-0.118,P＜0.01),depression(β=-0.105,P＜0.01),and loneliness(β=-0.322,P＜0.01).Loneliness positively predicted anxiety(β=0.348,P＜0.01)and depression(β=0.346,P＜0.01).Loneliness played a partial mediating role in the relationship of family function with anxiety and depression among medical students,with mediating effects of 49.0%and 43.2%,respectively.Conclusions:Family function not only directly affects medical students'anxiety and depression but also indirectly affects them by influencing loneliness.Therefore,improving medical students'family function can effectively reduce their loneliness,thereby helping to alleviate anxiety and depression.

Ovarian cancer is the most lethal malignancy affecting the female reproductive system. Pharmacological inhibitors targeting CDK4/6 have demonstrated promising efficacy across various cancer types. However, their clinical benefits in ovarian cancer patients fall short of expectations, with only a subset of patients experiencing these advantageous effects. This study aims to provide further clinical and biological evidence for antineoplastic effects of a CDK4/6 inhibitor (TQB4616) in ovarian cancer and explore underlying mechanisms involved. Patient-derived ovarian cancer organoid models were established to evaluate the effectiveness of TQB3616. Potential key genes related to TQB3616 sensitivity were identified through RNA-seq analysis, and TRIM4 was selected as a candidate gene for further investigation. Subsequently, co-immunoprecipitation and GST pull-down assays confirmed that TRIM4 binds to hnRNPDL and promotes its ubiquitination through RING and B-box domains. RIP assay demonstrated that hnRNPDL binded to CDKN2C isoform 2 and suppressed its expression by alternative splicing. Finally, in vivo studies confirmed that the addition of siTRIM4 significantly improved the effectiveness of TQB3616. Overall, our findings suggest that TRIM4 modulates ubiquitin-mediated degradation of hnRNPDL and weakens sensitivity to CDK4/6 inhibitors in ovarian cancer treatment. TRIM4 may serve as a valuable biomarker for predicting sensitivity to CDK4/6 inhibitors in ovarian cancer.

ObjectiveTo explore the protective effect and underlying mechanism of Gegen Qinliantang on cognitive function in db/db mice with diabetic cognitive impairment （DCI）. MethodsThirty-two 8-week-old male db/db mice were randomly assigned to the model group， dapagliflozin group （1.0 mg·kg^-1·d^-1）， low-dose Gegen Qinliantang group （6.24 g·kg^-1·d^-1）， and high-dose Gegen Qinliantang group （24.96 g·kg^-1·d^-1）. Eight db/m mice served as the normal group. All mice were administered the corresponding treatment once daily by gavage for 10 consecutive weeks. Body weight and fasting blood glucose （FBG） were dynamically monitored. The Morris water maze test was used to evaluate cognitive function. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe pathological changes in the hippocampus. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in hippocampal tissue. Immunofluorescence double staining was used to detect the co-expression of M1 microglial marker CD16/32 and ionized calcium-binding adapter molecule 1 （IBA1） in the hippocampus. Western blot analysis was performed to detect the protein expression of postsynaptic density protein 95 （PSD-95）， synapsin （SYN）， nuclear factor-κB p65 （NF-κB p65）， and phosphorylated NF-κB p65 （p-NF-κB p65） in the hippocampus. ResultsCompared with the normal group， the model group showed significantly increased body weight and FBG levels （P<0.01）， significantly prolonged escape latency and reduced platform crossings in the Morris water maze test （P<0.01）， disordered arrangement of hippocampal neurons， nuclear pyknosis， increased neuronal necrosis， reduced Nissl bodies， decreased expression of synaptic proteins PSD-95 and SYN （P<0.01）， increased CD16/32⁺ /IBA1⁺ positive rate， elevated levels of TNF-α and IL-1β， and an increased p-NF-κB p65/NF-κB p65 ratio （P<0.01）. Compared with the model group， the dapagliflozin group exhibited significantly reduced FBG levels at weeks 5 and 10 （P<0.05， P<0.01） and increased body weight. The high-dose Gegen Qinliantang group showed significantly reduced FBG at week 10 （P<0.05）. Escape latency was significantly reduced on days 3 and 5 of the water maze test in the dapagliflozin group and on day 5 in the high-dose Gegen Qinliantang group （P<0.05）. Platform crossings were significantly increased in both the dapagliflozin group and the high-dose Gegen Qinliantang group （P<0.05）. Hippocampal pathological damage was alleviated to varying degrees in the dapagliflozin group and the low- and high-dose Gegen Qinliantang groups， with significantly increased expression of PSD-95 and SYN （P<0.01）. Further studies revealed that both low- and high-dose Gegen Qinliantang reduced hippocampal IL-1β levels and the CD16/32⁺/IBA1⁺ positive rate of microglia， while the high-dose group also significantly reduced hippocampal TNF-α levels and the p-NF-κB p65/NF-κB p65 （P<0.05， P<0.01）. ConclusionGegen Qinliantang can improve hyperglycemia， cognitive dysfunction， and synaptic damage in DCI， inhibit M1 polarization of microglia and neuroinflammation， and its mechanism may be related to the inhibition of NF-κB activation.

Objective:To explore the association between big five personality traits, emotional coping information acquisition ability, and depressive symptoms among Chinese adults, providing theoretical support for behavioral intervention strategies targeting individuals with different personality traits and depressive symptoms.Methods:Data were obtained from the Psychology and Behavior Investigation of Chinese Residents (PBICR), a cross-sectional survey conducted from July to September 2021 across 120 cities in China, with 9 966 adults involved. The big five inventory-10 (BFI-10) and patient health questionnaire-9 (PHQ-9) were used to assess personality traits and depressive symptoms, respectively. Emotional coping information acquisition ability was evaluated using a four-point Likert scale. Multivariable binary Logistic regression analysis was performed using R 4.3.1 software to examine associations among big five personality, emotion-coping information acquisition ability, and depressive symptoms.Results:Among the 9 966 surveyed adults, 1 213 individuals(12.2%) who met the PHQ-9 criteria were assessed to have positive depressive symptoms. Difficulties in acquiring emotional coping information were reported by 1 934 individuals(19.4%). The scores of extraversion, agreeableness, neuroticism, openness and conscientiousness in big five personality traits were 6.26±1.58, 7.00±1.49, 6.26±1.49, 6.41±1.52 and 6.91±1.60, respectively. Inter-group comparisons reported statistically significant differences in the five major personality traits between the negative and positive group of depressive symptoms ( χ2=215.39, P<0.05). Logistic regression analysis showed that poor emotional coping information acquisition ability ( B=0.304, OR(95% CI)=1.36(1.15-1.59)) and dominant traits of extraversion ( B=0.597, OR(95% CI)=1.82(1.55-2.13)) or openness ( B=0.321, OR(95% CI)=1.38(1.10-1.72)) were significant risk factors for depression. Conclusions:Chinese adults with big five personality mainly presented as extroversion and openness traits, and with poor emotional coping and information acquisition abilities might be associated with depressive symptoms.
