Background Occupational health risk assessment is the foundation of safeguarding workers' occupational health. However, traditional assessment methods often fail to adequately account for health effects and enterprise-specific characteristics, limiting their comprehensive evaluation capabilities. Additionally, these methods suffer from inconsistent standards, narrow application scopes, insufficient hazard sub-categorization, and indicator systems that poorly support informatization and digital transformation. To address these gaps, this study proposes methodological innovations focusing on the assessment indicator system. Objective To construct a systematic, generalizable, and practical occupational health comprehensive risk assessment indicator system by leveraging occupational health practices and surveillance big data from Shanghai. Methods Initial system indicators were extrated through literature review. Subsequently, expert interviews and group discussions, combined with occupational health surveillance big data, were used to refine these indicators, forming a candidate pool covering two major dimensions: risk factor characteristics and enterprise characteristics. The Delphi method was applied to evaluate and screen the indicators, while the analytic hierarchy process (AHP) was used to construct a hierarchical model and determine indicator weights. Results A total of 76 articles were reviewed, identifying 25 candidate indicators. After two rounds of Delphi expert consultation, 8 primary indicators (e.g. hazard characteristics, exposure characteristics, health effects, industry characteristics, management characteristics, protective features, adverse events, and uncertainty) and 17 secondary indicators (hazard factor characteristics, exposure levels, number of people exposed, number of factor exposure, special physical exam indicators, suspected occupational diseases, occupational diseases, industry categories, organizational management, hazard reporting, occupational health training, hazard factor testing, occupational health exams, protective facilities, personal protective equipment, administrative penalties, and data quality) were finalized. The expert response rate was 100%, and the expert authority coefficient was 0.86. The Kendall's W coefficients for importance and accessibility scores across the two consultation rounds were 0.41, 0.40 and 0.41, 0.50. A hierarchical model targeting the comprehensive occupational health risk index was constructed, comprising two major elements and three levels of indicators. AHP was applied to calculate the weights, with all judgment matrices demonstrating satisfactory consistency (consistency ratio < 0.1). Conclusion By integrating risk factor profiles with enterprise-specific characteristics via the Delphi-AHP approach, a robust occupational health comprehensive risk assessment indicator system is established. This system provides a practical framework for digitized occupational health management, though further empirical validation in real-world settings is warranted.

OBJECTIVE To investigate the current status of informatization tools applied to antimicrobial stewardship in county hospitals in China， and to provide a reference for promoting the informatization development of antimicrobial stewardship in county hospitals.METHODS From August to September 2025， an online questionnaire survey was conducted among 1 007 county hospitals across 31 provinces（autonomous regions， and municipalities） in China. The survey focused on the application of four types of informatization tools：the real-time monitoring system for antimicrobial use， the pre-prescription review system， the irrational use warning system， and the electronic prescription evaluation system（hereinafter referred to as the “monitoring system”“review system”“warning system”“evaluation system”，respectively）. Correlation analysis and binary Logistic regression analysis were employed to explore the influencing factors.RESULTS Of the county hospitals， 80.83% were equipped with at least one type of informatization tool for antimicrobial stewardship， while 19.17% had no relevant tool. Only 18.87% of the hospitals were equipped with all four types of tools. The monitoring system exhibited the highest equipped rate （70.80%）， whereas the warning system was equipped in only 33.96% of the hospitals. Four types of tools are evenly and adequately deployed in the eastern region， the central and western regions have far lower deployment rates of intervention tools including review system and warning system， accompanied by prominent intra-provincial gaps. The total number of the health technicians， hospital grade， and prescription review rate of outpatient antibacterial drug were significantly and positively correlated with the deployment rates of the four informatization tools （ P ＜0.05）. The results of the Logistic regression model fitting indicated that the model of the review system was rated “excellent” [area under the receiver operating characteristic curve （AUC）＝0.81]， and the model of the warning system was rated “further improvement” （AUC＝0.67）. The total number of health technicians was significantly positively correlated with the deployment rates of all four types of informatization tools （all P ＜0.05）.CONCLUSIONS The informatization of antimicrobial stewardship in county hospitals in China remains in the initial stage of transitioning from “passive statistics” to “active prevention and control”， with challenges such as structural imbalance and regional disparities. In the future， differentiated support strategies should be implemented， the allocation of resources should be optimized， to enhance the level of refined antimicrobial stewardship.

AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

ObjectiveTo explore the therapeutic effects and mechanisms of modified Danggui Shaoyaosan on acne based on the c-Jun N-terminal kinase （JNK）/p38 mitogen-activated protein kinase （p38 MAPK） pathway. MethodsA rat ear acne model was established in SD rats， and the rats were divided into a blank group， a model group， and low-， medium-， and high-dose groups of modified Danggui Shaoyaosan （7.15， 14.30， 28.60 g·kg·d^-1）， with six rats in each group. After the administration for 14 consecutive days， morphological changes in the rats' auricles were observed， and hematoxylin-eosin （HE） staining was used to examine the pathological changes in the acne-affected ear tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the ear tissue. Quantitative reverse transcription polymerase chain reaction （Real-time PCR） was performed to detect the mRNA expression levels of Caspase-3， B cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， JNK， and p38 MAPK in the ear tissue. Additionally， Western blot analysis was conducted to assess the protein levels of Caspase-3， Bcl-2， Bax， JNK， and p38 MAPK in the ear tissue. The active components and key targets of modified Danggui Shaoyaosan in the treatment of acne were identified through network pharmacology analysis. Molecular docking was then employed to evaluate the interactions between the main active components and the key targets. ResultsThe results of the animal experiment demonstrated that compared with those in the blank group， rats in the model group exhibited redness， swelling， thickening， hardening， dryness， and roughness of the auricle. The surface showed sebaceous scales and desquamation， accompanied by acne-like lesions such as papule-like elevations or cysts. Histopathological changes included keratinization， epidermal thickening， dermal collagen fiber degeneration and necrosis， subcutaneous muscle degeneration and necrosis， inflammatory cell infiltration， and fibrous tissue proliferation. The mRNA and protein expression levels of IL-1β， TNF-α， Caspase-3， Bax， JNK， and p38 MAPK were significantly increased （P<0.01）， while those of Bcl-2 were significantly decreased （P<0.01）. In comparison to the model group， the modified Danggui Shaoyaosan groups showed marked improvement in acne-like lesions of the auricle， with varying degrees of histopathological damage reduction. Additionally， the mRNA and protein expression levels of IL-1β， TNF-α， Caspase-3， Bax， JNK， and p38 MAPK in the tissue were significantly decreased （P<0.05， P<0.01）， while those of Bcl-2 were significantly increased （P<0.05， P<0.01）. Network pharmacology analysis indicated that the key compounds in modified Danggui Shaoyaosan responsible for its effects in treating acne may include acacetin， kaempferol， luteolin， quercetin， wogonin， and baicalein. These compounds exerted their effects by modulating core targets such as TNF， IL-1β， Caspase-3， and Bcl-2， thereby alleviating inflammation and apoptosis and ultimately improving acne symptoms. ConclusionModified Danggui Shaoyaosan may exert its therapeutic effects on acne by inhibiting the activation of the JNK/p38 MAPK pathway， thereby alleviating inflammation and apoptosis.

With the development of neuroscience and oncology, the direct regulation effect of central nervous system circuits on tumors has been gradually revealed. Evidence indicates that the therapy targeting emotion-related encephalic regions may have great potential in blocking the promotion of breast cancer progression by depression. The underlying complex mechanisms involve the generation of depression and the regulation of tumors by central nervous system circuits. However, a systematic summary is lacking in this field. This article reviews the latest research progress of the central nervous system circuits and the generation of depression, the neural connection between the central nervous system and peripheral tumor, and the regulation of the tumor immune microenvironment by the sympathetic nervous system. It also systematically investigates the potential mechanism of the central nervous system circuit in the promotion of breast cancer progression by depression to establish new solutions for the comprehensive treatment of breast cancer.

OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows， providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject， a comprehensive drug traceability system was established through three key interventions： upgrading the information system architecture [including integration of the hospital information system （HIS） with the traceability platform]， workflow optimization （reorganizing the inventory-dispensing-verification tripartite process）， and designing a dual-mode traceability data collection mechanism （primary data capture at dispensing stations and supplementary capture at verification stations）. Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management， in terms of data collection: Mode Ⅰ （verification-stage capture） uploaded 26 144 records， while Mode Ⅲ （inventory-as-sales capture） uploaded 443 061 records， totaling 469 205 entries； in terms of time efficiency： average drug dispensing time increased from 28.74 s to 43.37 s （enhanced by 51%）. Through dynamic staffing adjustments， patient wait time only extended from 8.04 min to 8.67 min （enhanced by 8%）. CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy， leveraging informatization （e.g.， dual-mode data capture） to offset manual operation delays， which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

BACKGROUND: Lung cancer is the leading malignancy in China in terms of both incidence and mortality. With increased health awareness and the widespread use of low-dose computed tomography (CT), early diagnosis rates have been steadily improving. Surgical intervention remains the primary treatment option for early-stage lung cancer, and video-assisted thoracoscopic surgery (VATS) has become a common approach due to its minimal invasiveness and rapid recovery. However, post-discharge recovery remains incomplete, underscoring the importance of postoperative care. Traditional follow-up methods, lack standardization, consume significant medical resources, and increase the burden of the patients. Artificial intelligence (AI)-driven disease management platforms offer a novel solution to optimize postoperative follow-up. This study followed 463 lung cancer surgery patients using an AI-based platform, aiming to identify common postoperative issues, propose solutions, improve quality of life, reduce recurrence-related costs, and promote AI integration in healthcare. METHODS: Using the AI disease management platform, this study integrated educational videos, collaboration between healthcare teams and AI assistants, daily health logs, health assessment forms, and personalized interventions to monitor postoperative recovery. The postoperative rehabilitation status of the patients was assessed by the Leicester Cough Questionnaire (LCQ-MC). Two independent t-test and one-way ANOVA were used to analyze the causes of postoperative cough in lung cancer. RESULTS: Most issues occurred within 7 d post-discharge, significantly declined on 14 d post-discharge. Factors such as gender, smoking history, and surgical approaches were found to influence cough recovery. The incidence of cough on 7 d post-discharge in females was higher than that in males (P<0.01), while the incidence of cough on 14 d post-discharge in elderly patients was lower than that in young patients (P=0.03). The AI-based platform effectively addressed cough, pain, and sleep disturbances through phased interventions. CONCLUSIONS The AI-based platform significantly enhanced postoperative management efficiency and the self-care capabilities of the patients, particularly in phased cough management. Future integration with wearable devices could enable more precise and personalized postoperative care, further advancing the application of AI technology across multidisciplinary healthcare domains.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Objective To understand the current situation of the management of patients'self-provided infusion drugs in secondary and above general hospitals in China,and to provide a theoretical and practical basis for improving the management system.Methods The annual pharmacy professional quality control work survey conducted by the National Pharmaceutical Management Professional Quality Control Center was used to obtain information on the management of patients'self-provided infusion drugs in secondary and above general hospitals in 31 provinces(autonomous regions and municipalities directly under the central government)and the Xinjiang Production and Construction Corps of Chinese mainland from 2020 to 2022,and was summarized and calculated using data-processing software.Results The total number of secondary and above general hospitals included in the analysis from 2020 to 2022 is 4 786,5 063 and 6 041,respectively.In 2022,compared with 2020,the percentage of hospitals allowing patients to use self-provided infused drugs decreased from 55.08％to 48.54％,the percentage of hospitals that have established a system for managing patients' self-provided drugs increased from 81.54％to 98.09％,and the percentage of hospitalized patients' use of self-provided drugs that are all documented in their medical orders increased from 79.76％to 90.72％.The types of drugs that hospitals allow patients to use for self-provided infusion are mainly antitumor drugs,the places where self-provided infusion drugs are dispensed are mainly clinical departments(wards),and the main source of self-provided infusion drugs is self-pickup by patients.Conclusion Hospitals should establish a management system for patients'self-provided drugs,strengthen the information management of self-provided infusion drugs,and ensure drug supply and medication safety for patients.

Objective To explore the mediating effect of community elderly care service on the influence of social isolation on cognitive function of the elderly.Methods Based on the data of China Health and Retirement Longitudinal Study in 2018,mini mental status examination(MMSE)was used to assess the cognitive function of the elderly.Multivariate Logistic regression was used to analyze the influence of individual characteristics and social isolation on cognitive function of the elderly,and the correlation among social isolation,community elderly care service and cognitive function was analyzed through mediating effect.Results A total of 6615 elderly individuals were included,among whom 2906 cases(43.93％)had cognitive impairment.The results of multivariate Logistic regression analysis indicated that social isolation,age,gender,educational level,place of residence,marital status,activities of daily living ability,smoking,sleep duration,loneliness,community elderly care service,social interaction,and less than one contact with children per week were all influencing factors for the occurrence of cognitive impairment in the elderly(P＜0.05).Community elderly care service exerted a partial mediating effect in the impact of social isolation on the cognitive function of the elderly.Conclusion Social isolation is a risk factor for cognitive impairment in the elderly,and community elderly care service is a protective factor for cognitive impairment in the elderly.It is necessary to improve the coverage and utilization rate of community elderly care service support,improve the social isolation of the elderly,and protect the cognitive function of the elderly.
