Work serves as a critical means of obtaining resources, facilitating personal growth, realizing self-worth, and engaging in social interactions. However, work-related diseases pose significant threats to workers’ health and productivity, and impose considerable economic burdens. This article categorized work-related diseases into six major types, including musculoskeletal disorders, mental and behavioral disorders, cardiovascular and metabolic diseases, digestive system diseases, reproductive system diseases, and non-specific respiratory diseases, and summarized their risk factors, assessment methods, policy regulation, and prevention and control measures. Current research in this field predominantly relies on cross-sectional studies, which present limitations in causal inference and potential risks of bias. Future studies should expand sample sizes, optimize research designs, and establish multidimensional evaluation systems to comprehensively assess the health and economic impacts of work-related diseases. It is recommended to enhance the translation of research findings into practice, thereby providing a scientific basis for the occupational health protection system and promoting the well-being and sustainable development of the working population.

OBJECTIVE To study the efficacy of Tianjiang xueshuantong pills in the treatment of coronary heart disease. METHODS In accordance with the common pathogenesis of coronary heart disease， acute myocardial ischemia model， hyperlipidemia model， blood stasis model， and carotid artery thrombosis model were established using Wistar rats or SD rats as the experimental subjects. The effects of Tianjiang xueshuantong pills administered at high， medium， and low doses （0.6， 1.2 and 2.4 g/kg） on hemodynamic parameters and myocardial enzyme markers [lactate dehydrogenase （LDH）， creatine kinase-MB （CK- MB）]， oxidative stress factors [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione （GSH）]， inflammatory cytokines [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， monocyte chemotactic protein-1 （MCP-1）， intercellular adhesion molecule-1 （ICAM-1）]， myocardial infarction percentage， serum lipid indexes [total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）]， platelet aggregation function 话：022-84845240。E-mail：jiangx@tjipr.com [maximum aggregation rate （MAR）]， and thrombus formation indexes [thrombosis time， thrombus mass， thrombus protein content， plasminogen activator inhibitor-1 （PAI-1）， and tissue-type plasminogen activator （t-PA）] were evaluated in the rat models. RESULTS In myocardial ischemia tests， Tianjiang xueshuantong pills significantly reduced the percentage of myocardial infarction and the levels of CK-MB， LDH， MDA， GSH， IL-6， TNF-α， IL- 1β， and MCP-1 in serum （P＜0.05 or P＜0.01）. In hyperlipidemia tests， high dose of Tianjiang xueshuantong pills significantly reduced the serum levels of TC， LDL and significantly increased the level of HDL in rats after 2 weeks and 4 weeks of administration. In blood stasis tests， different doses of Tianjiang xueshuantong pills significantly reduced MAR of rats （P＜0.01）. In artery thrombosis tests， high dose of Tianjiang xueshuantong pills significantly prolonged the time of thrombosis formation （P＜ 0.01）， significantly reduced the weight and protein content of thrombus and the level of PAI-1 in serum （P＜0.01）. CONCLUSIONS Tianjiang xueshuantong pills exert therapeutic effects on coronary heart disease through multi-dimensional synergistic actions， including anti-myocardial ischemia， lipid-lowering， and anti-thrombotic effects.

BACKGROUND:Postoperative adjuvant chemotherapy is a common method for the treatment of gastric cancer,but the curative effect of chemotherapy in different patients varies considerably.A new pre-clinical treatment model is needed to guide personalized drug therapy for patients with gastric cancer.OBJECTIVE:To construct organoid model based on gastric cancer tissue and investigate its application in personalized drug screening.METHODS:The tissue samples of 20 patients with gastric cancer were collected,digested and decomposed,mixed with matrix glue,and cultured with organoid medium containing epidermal growth factor and fibroblast growth factor 10.Hematoxylin-eosin staining and immunohistochemical method were used to verify the homogeneity of pathological morphology and immune molecular markers of gastric cancer organoids and original tumor tissues.The feasibility of the established gastric cancer organoid model for drug screening was evaluated through drug sensitivity screening of six drugs including carboplatin,irinotecan,fluorouracil,oxaliplatin,paclitaxel,and epirubicin.RESULTS AND CONCLUSION:Fourteen organoids of gastric cancer cases were successfully cultured.There were individual differences in morphology and growth characteristics of organoids.All organoids could be stably passed through,froze and resuscitated.Gastric cancer organoids retained the same morphological features and immunomolecular expression as primary tumor tissues.Six organoids showed different drug sensitivities to six chemotherapy drugs,which initially confirmed the feasibility of gastric cancer organoids as a drug screening model in vitro.

Objective To investigate the application value of arterial spin labeling(ASL)perfusion weighted imaging in the early diagnosis of Alzheimer's disease(AD).Methods A total of 60 patients with different ages(control group)and 60 AD patients with different degrees(patient group)who underwent cerebral ASL perfusion weighted imaging examination were selected.At the work-station,the region of interest(ROI)of the hippocampus and limbic system brain structures were delineated and the cerebral blood flow(CBF)value of the ROI were measured.The CBF values of the brain structures of the control group at different ages and the corresponding ROI of the control group and the patient group were compared.Results There were statistically significant differences in the CBF values of the cingulate gyrus,parahippocampal gyrus,hippocampus,orbital part of frontal lobe,temporal pole of temporal lobe,insula lobe and amygdaloid body of the limbic system among the different ages in the control group(P＜0.05),and the CBF value of brain structures gradually decreased with the increase of age.There were statistically significant differences in CBF values of ROI between the control group and mild,moderate,severe patient group(P＜0.05),and the CBF value of brain structures gradually decreased with the severity of AD condition.Conclusion The CBF value of ASL perfusion weighted imaging can objectively reflect the blood flow changes and functional status of the hippocampus and limbic system brain structures in elderly people of different ages and AD patients of different degrees,and has important value in the early diagnosis of AD patients.

Digital technology provides a powerful and effective approach to address the bottlenecks in integrity supervision within public hospitals.Through semi-structured interviews conducted at Hospital Y in Zhejiang Province,this study reveals that current applications of digital technology for integrity supervision in public hospitals remain largely confined to independent utiliza-tion of departmental data resources within isolated platforms.These applications primarily focus on three key areas:disciplinary inspection supervision,ethics and conduct supervision,and operational supervision,which have demonstrated practical benefits including enhanced efficiency of integrity supervision,standardized management of institutional behaviors,and improved accessi-bility of public oversight.To address the structural dilemmas of system integration barriers under fragmented governance,the data governance challenges of standard heterogeneity and connectivity barriers,and the application paradox arising from the technologi-cal-practical misalignment,the study proposes three pathways:advancing governance through institutionalized top-level design,building integrated platforms to dismantle data silos,and strengthening technology application to deepen empowerment effects.

Objective:To investigate the knowledge and practice of the Sixth Chinese national consensus report on the management of Helicobacter pylori ( H. pylori) infection (treament excluded) (referred to as sixth national consensus)and 2022 Chinese national clinical practice guideline on H. pylori eradication treatment (referred to as guideline) among gastroenterologists in China, so as to provide out relevant training in the future. Methods:A questionnaire was designed according to sixth national consensus and guideline, including knowledge and practice of sixth national consensus and guideline, and the detection, indications of eradication, the relationship between infection and gastrointestinal microbiota, and eradication of H. pylori. From November 1 to 30 in 2023, the questionnaire-based survey was conducted among 1 506 gastroenterologists from secondary and tertiary hospitals of 24 provinces, autonomous regions and municipalities in China with convenience sampling method using the "Questionnaire Star" online questionnaire platform and the questionnaire link was sent by WeChat. Descriptive methods were used for statistical analysis. Results:A total of 1 442 valid questionnaires were collected. The awareness rate of sixth national consensus and guideline of gastroenterologists was 83.7% (1 207/1 442), and 47.2% (680/1 442) had read the relevant content in detail. Urea breath test (97.4%, 1 404/1 442) was the most commonly used method for diagnosing current H. pylori infection, however, more than half of the physicians chose serological test (53.3%, 769/1 442) for the diagnosis of current infection. The common indications of H. pylori eradication could be identified by 84.3%(1 215/1 442) of gastroenterologists. The most well-known eradication regimen was bismuth quadruple regimen (98.5%, 1 421/1 442), while some physicians still believed that the standard triple regimen (31.8%, 459/1 442) and sequential regimen (21.9%, 316/1 442) were recommended by the guideline. A further 20.2% (291/1 442) frequently prescribed a triple regimen combined with gastric mucosal protectants and the awareness rate of high-dose dual regimen was 59.1% (852/1 442). Amoxicillin + clarithromycin (65.4%, 943/1 442) and amoxicillin+ furazolidone (20.1%, 290/1 442) were commonly used antibiotic combinations in bismuth quadruple therapy. Potassium-competitive acid blockers and double-dose proton pump inhibitors were commonly used in bismuth quadruple therapy by 45.4% (655/1 442) and 46.0% (664/1 442) of physicians, respectively. For patients with multiple failed eradications, furazolidone was the most commonly used antibiotic for re-eradication(71.7%, 1 034/1 442). Conclusion:The knowledge and practice of gastroenterologists on H. pylori infection in China deviates from the new consensus and guideline, and more publicity and training should be carried out in future to improve the ability of gastroenterologists to standardise the diagnosis and treatment of H. pylori infection.

Purpose To investigate the expression of fork-head box protein A1(FOXA1)in esophageal squamous cell car-cinoma(ESCC)and its association with clinicopathologic char-acteristics and prognosis.Methods Immunohistochemistry was used to detect FOXA1 protein expression in 532 cases of esopha-geal squamous cell carcinoma.The correlation between FOXA1 protein expression and clinicopathologic features and prognosis of patients was analyzed.Results In 532 cases of esophageal squamous cell carcinoma,183 cases overexpressed FOXA1 pro-tein(34.4％).FOXA1 overexpression was associated with ES-CC vascular infiltration(P=0.032),poorly differentiation(P=0.032),and tumor size(P＜0.001).The overall survival(OS)and disease free survival(DFS)of patients with stage Ⅰ+Ⅱ esophageal squamous cell carcinoma with high FOXA1 ex-pression tended to be poor(OS:P=0.094;DFS:P=0.107).In ESCC patients with survival longer than 24 months,the high FOXA1 expression group had significantly shorter OS and DFS(OS:P=0.048;DFS:P=0.047).Multivariate survival anal-ysis showed that the depth of tumor invasion was an independent prognostic factor affecting the prognosis of esophageal squamous cell carcinoma.Conclusion FOXA1 is overexpressed in e-sophageal squamous cell carcinoma,and its high expression is related to tumor size,vascular infiltration and poorly differentia-tion.Patients with high FOXA1 expression tended to have poor prognosis in OS and DFS.When OS and DFS≥24 months,high FOXA1 expression may be used as a reference indicator for poor prognosis in ESCC patients.
