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 It investigates the current status of negative defensive medical behavior tendencies among medical students and explores influencing factors,aiming to provide evidence for improving medical students' propensity for negative defensive medical practices.Methods In February 2023,a cluster sampling approach was employed to recruit 297 medical students from a medical college-affiliated hospital in Province H.Descriptive statistics,chi-square tests,and correlation analyses were conducted to assess negative defensive medical behavior tendencies.Structural equation modeling(SEM)was utilized to explore multidimensional influencing factors.Results 45％of medical students demonstrated high-level negative defensive medical behavior tendencies.Statistically significant differences were observed between genders(x2=5.569,P＜0.05)and only-child/non-only-child groups(x2=6.104,P＜0.05).Positive correlations were identified between negative defensive medical behaviors and role stress(r=0.217,P＜0.01),negative organizational environment evaluation(r=0.395,P＜0.01),and negative social environment evaluation(r=0.405,P＜0.01).Only-child status was confirmed as an influencing factor(β=-0.123,P=0.036).Negative organizational environment evaluation(β=0.504,P＜0.001)and negative social environment evaluation(β=0.193,P=0.039)showed significant positive effects.Conclusion Immediate interventions-including role-specific risk allocation,organizational ecosystem reconstruction,and social environment governance-require urgent implementation to address early-stage behavioral deviance,counteract the solidification of defensive medical thinking patterns,and reduce predispositions toward negative professional behaviors among medical trainees.

Objective:To analyze the application of mobile application-based decision support tools in patient treatment decision-making both domestically and internationally, and to provide references and insights for future research in this area.Methods:A search was conducted in databases including China National Knowledge Infrastructure, VIP, Wanfang, China Biology Medicine disc, PubMed, Embase, CINAHL, and Web of Science for relevant studies on the application of mobile application-based decision support tools in patient treatment decision-making, with the search period extending from database inception to April 1, 2024. The scope review methodology by Arksey and O'Malley was used to guide the literature summary and analysis.Results:A total of 9 studies were included in the review. The main presentation forms of mobile application-based decision support tools in patient treatment decision-making were text, charts, and videos. The main contents included assessing patients' decision-making needs, providing informational support, and summarizing the decision-making process. The evaluation criteria focused on 2 areas: decision quality (preparedness for decision-making, self-efficacy, decision conflict, regret, actual participation, satisfaction, knowledge of the disease, and treatment choices) and psychological state.Conclusions:It is recommended that future researchers fully consider patients' treatment decision-making needs and preferences, provide a more diverse range of information presentation methods, and strengthen the comprehensiveness and scientific basis of the content. These improvements aim to enhance decision quality and, through multi-center, large-sample, high-quality studies, further explore the effectiveness of these tools in clinical applications, thereby providing more evidence for their widespread adoption.

Objective To analyze the influence path of medical students'professional identity on positive defensive medical behaviors and examine the mediating effect of medical risk perception between the two,aiming to provide theoretical support and practical reference for medical education to actively adapt to the demands of the medical and health system reform and promote the scientific guidance of positive defensive medical behaviors.Methods ln 2020,a questionnaire survey was conducted among medical students from four medical colleges in Heilongjiang Province using cluster sampling method,and data analysis was performed using SPSS 27.0 software.Results Medical students'professional identity showed a significant positive correlation with their positive defensive medical behavior(β=0.225,P＜0.001),with medical risk perception acting as a partial mediator(indirect effect accounting for 19%of the total effect).Professional identity(β=0.183,P＜0.001)and medical risk perception(β=0.195,P＜0.001)exerted direct positive effects on positive defensive medical behavior.Conclusion Medical students'professional identity drives them to adopt positive defensive medical behaviors by strengthening their sense of responsibility ethics and risk cognition ability,and medical risk perception is a key mediating variable in this process.Educational management should integrate policy-oriented clinical decision-making training and balance medical safety and efficiency through the collaborative mechanism of"professional identity-risk perception-behavioral practice".

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.
