This study analyzes the legal application of a dispute over employer identification in a case of occupational heat illness caused by part-time work to clarifying matters related to employer determination in occupational disease diagnosis using a case analysis method and factual reconstruction. The analysis is based on relevant civil laws and regulations, occupational disease diagnosis laws and regulations, and jurisprudential theories. The occupational disease diagnostic institution identified the part-time employer as responsible for the patient′s heat illness, which was both reasonable and lawful. This attribution safeguarded the rights of the worker, the primary employer, and the part-time entity. In occupational disease diagnosis, attention should be paid to de facto employment relationship, and the principle of "accountability lies with the actual employer at the time of the incident" should be followed to standardize employer identification. The health administrative department has supervisory responsibilities over occupational disease diagnoses. Workers′ compensation rights can be protected through the advance payment mechanism for work-related injury insurance. It is recommended to further improve internal procedures for occupational disease diagnosis, strengthen the dissemination of relevant laws and regulations and enhance the capabilities of occupational disease diagnosis physicians, to further protect workers' occupational health and their associated legal rights.

BACKGROUND: The proportion of patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations is relatively high in China. However, these patients currently lack significant benefits from available neoadjuvant treatment options. This study aims to explore the potential application value of neoadjuvant targeted therapy by evaluating its efficacy and safety in patients with EGFR-mutant resectable lung adenocarcinoma. METHODS: A multicenter retrospective study was used to analyze the treatment effect of patients with stage IIA-IIIB EGFR-mutant lung adenocarcinoma who underwent surgical resection after receiving neoadjuvant targeted therapy from July 2019 to October 2024. RESULTS: A total of 24 patients with EGFR-mutant lung adenocarcinoma from three centers were included in this study. All patients successfully underwent surgery and achieved R0 resection of 100.0%. The objective response rate (ORR) was 83.3% (20/24) . The major pathologic response (MPR) rate was 37.5% (9/24), with 2 patients (8.3%) achieving pathological complete response (pCR). During neoadjuvant therapy, 13 out of 24 patients (54.2%) experienced adverse events of grade 1-2, with no occurrences of ≥ grade 3. The most common treatment-related adverse events were rash (n=4, 16.7%), mouth sores (n=2, 8.3%), and diarrhea (n=2, 8.3%). The median follow-up time was 33.0 months, no deaths occurred in all patients, and the overall survival (OS) rate was 100.0%. The 1-year disease-free survival (DFS) rate was 91.1%, and the 2-year DFS rate remained at 86.2%. CONCLUSIONS The application of neoadjuvant targeted therapy in patients with EGFR-mutant resectable lung adenocarcinoma is safe and feasible, and is expected to become a highly promising neoadjuvant treatment option for the patients with EGFR-mutant lung adenocarcinoma.

As the management system of Occupational Medical Examination (OME) institutions is moving to a record-filing model, the traditional management approach might not fulfill the current policy requirements. There is a pressing need for development of high-quality occupational health management system. In this context, the Guangdong Provincial Occupational Health Examination Quality Control Center (hereinafter referred to as the "Provincial Quality Control Center") pioneered the integration of the Performance Excellence Model (PEM) framework into the macro-quality management of OME institutions in Guangdong Province. In light of the current research gaps in the field of macro-quality management for OME institutions, the Provincial Quality Control Center, based on the core principles and standards of PEM, has closely aligned with the professional characteristics of occupational health examinations. The established macro-quality management innovation in OME institutions in Guangdong Province consists of seven dimensions: strategic direction, leadership development, identification of key management subjects, data analysis and management, human resources allocation, process optimization, and the application of quality control outcomes. This system has provided a robust impetus for the ongoing improvement of quality control efforts. The initial implementation of PEM demonstrated notable improvements in macro-quality management for OME institutions. Moving forward, the Provincial Quality Control Center will continue to strengthen the development of key technical personnel, innovate training models, harness the advantages of big data technology, restate and upgrade the system continuously, and refine the macro-quality management mechanisms of OME institutions to ensure that the health rights and interests of workers and employers are effectively safeguarded and enhanced.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:Osteosarcoma is a highly aggressive primary malignant bone tumor commonly seen in children and adolescents,with a poor prognosis.Anchorage-dependent cell death(anoikis)has been proven to be indispensable in tumor metastasis,regulating the migration and adhesion of tumor cells at the primary site.However,as a type of programmed cell death,anoikis is rarely studied in osteosarcoma,especially in the tumor immune microenvironment.This study aims to clarify prognostic value of anoikis and tumor immune microenvironment-related gene in the treatment of osteosarcoma. Methods:Anoikis-related genes(ANRGs)were obtained from GeneCards.Clinical information and ANRGs expression profiles of osteosarcoma patients were sourced from the therapeutically applicable research to generate effective therapies and Gene Expression Omnibus(GEO)databases.ANRGs highly associated with tumor immune microenvironment were identified by the estimate package and the weighted gene coexpression network analysis(WGCNA)algorithm.Machine learning algorithms were performed to construct long-term survival predictive strategy,each sample was divided into high-risk and low-risk subgroups,which was further verified in the GEO cohort.Finally,based on single-cell RNA-seq from the GEO database,analysis was done on the function of signature genes in the osteosarcoma tumor microenvironment. Results:A total of 51 hub ANRGs closely associated with the tumor microenvironment were identified,from which 3 genes(MERTK,BNIP3,S100A8)were selected to construct the prognostic model.Significant differences in immune cell activation and immune-related signaling pathways were observed between the high-risk and low-risk groups based on tumor microenvironment analysis(all P<0.05).Additionally,characteristic genes within the osteosarcoma microenvironment were identified in regulation of intercellular crosstalk through the GAS6-MERTK signaling pathway. Conclusion:The prognostic model based on ANRGs and tumor microenvironment demonstrate good predictive power and provide more personalized treatment options for patients with osteosarcoma.

Objective:To explore the predictive value of lipoproteins on the progression of critically ill patients to chronic critical illness (CCI).Methods:A retrospective cohort study was conducted to analyze clinical data of patients admitted to the intensive care unit (ICU) of Nanjing Drum Tower Hospital from January 1, 2020, to December 31, 2022. The levels of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and apolipoproteins (ApoA-Ⅰ, ApoB) at 1, 3, 7, 14 and 21 days after admission to ICU were collected. The progression to CCI was recorded. CCI was defined as the length of ICU stay ≥14 days with sustained organ dysfunction [sequential organ failure assessment (SOFA) score ≥2]. Differences in lipoprotein levels between the patients with and without CCI were compared. Multivariate Logistic regression was used to analyze risk factors for critically ill patients progressing to CCI. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of lipoproteins on critically ill patients progressing to CCI.Results:A total of 200 patients were enrolled in the final analysis. 137 patients (68.5%) progressed to CCI, and 63 patients (31.5%) did not. The lipoprotein indicators in the CCI group showed a decrease after the acute phase, while the lipoprotein indicators in the non-CCI group showed an increase. The levels of HDL, LDL, ApoA-Ⅰ, and ApoB at various time points in the CCI group were significantly lower than those in the non-CCI group. HDL at 7 days in the CCI group was significantly lower than that in the non-CCI group [mmol/L: 0.44 (0.31, 0.61) vs. 0.67 (0.49, 0.75), P < 0.01]. Multivariate Logistic regression analysis showed that 7-day HDL was an independent risk factor for critically ill patients progressing to CCI [odds ratio ( OR) = 0.033, 95% confidence interval (95% CI) was 0.004-0.282, P = 0.002]. ROC curve analysis showed that the area under the ROC curve (AUC) of 7-day HDL for predicting critically ill patients progressing to CCI was 0.702, with a 95% CI of 0.625-0.779, P < 0.001. When the optimal cut-off value was 0.59 mmol/L, the sensitivity was 69.8%, and the specificity was 72.4%. Conclusions:The low level of lipoproteins is closely related to the progression of critically ill patients, and 7-day HDL has a certain predictive value for critically ill patients progressing to CCI. Continuously observation of the change trend of lipoprotein level is helpful to judge the progression of CCI in critically ill patients.

[Objective] To explore the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou, and to investigate the correlation between donation frequency and these factors. [Methods] A cross-sectional study was conducted among 13 042 whole blood donors from 17 street blood donation sites of Guangzhou Blood Center from May to August 2020. Descriptive analysis was used to describe the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou. Ordinal multinomial logistic regression model was used to analyze the correlation between donation frequency and these factors. [Results] It was found that some of 13 042 blood donors had unhealthy habits, such as 6.8% (698/10 214，2 828 missing values) had severe tobacco dependence, 30.6% (3 997/13 042) had low exercise levels, 38.8%（5 056/13 042）had poor sleep quality, and 2.2% (271/12 159，883 missing values) had alcohol dependence. In addition, 2.8% (364/13 042) and 1.3% (172/13 042) of the donors may have moderate to severe depression and anxiety symptoms, respectively. The results of the ordinal multinomial logistic regression model showed that exercise level was significantly negatively correlated with the degree of depression and anxiety among blood donors. With the decrease in exercise level, the possibility of depression and anxiety among donors increased significantly. BMI, household income, education level, marital status, donation frequency, alcohol consumption and smoking had no significant correlation with the mental health status of donors. [Conclusion] Improving the exercise habits of blood donors may help enhance their mental health level. It is recommended that blood station staff strengthen the content of exercise when providing health education to blood donors to maintain a healthy lifestyle. It also suggests that there may be a certain degree of under-diagnosis of mental health problems in the process of health consultation before blood donation, and conducting more comprehensive and effective mental health assessments for blood donors is recommended.

Objective To analyze the epidemic status of newly diagnosed occupational diseases in Guangdong Province during the “13th Five-Year Plan” period, and scientifically evaluate the critical risk factors for occupational disease prevention and control. Methods The data of newly diagnosed occupational diseases reported by internet in Guangdong Province from 2016 to 2020 was collected from Report Card of Occupational Diseases using Occupational Diseases and Health Hazard Factors Monitoring Information System under China Disease Prevention and Control Information System. Data was used to determine the epidemic status and identify key risk factors. Results A total of 4 846 cases of occupational diseases were reported in Guangdong Province during the “13th Five-Year Plan”period, with an increase rate of 39.13% compared with the “12th Five-Year Plan” period (3 483 cases). The annual distribution of newly diagnosed occupational disease cases showed a trend of increasing and then declining. The top five percentage on types of occupational diseases were occupational noise-induced deafness, occupational silicosis, occupational chronic benzene poisoning, other occupational pneumoconiosis and occupational hand-arm vibration disease, accounting for 45.23%, 16.28%, 11.52%, 7.92% and 4.60%, respectively. Cases from the Pearl River Delta region accounted for 92.76%, while five non-Delta cities had “zero reported cases”. Regarding industry sector, cases were primarily concentrated in manufacturing, construction, and mining, accounting for 84.21%, 5.49% and 3.59%, respectively. Regarding industry categories, cases were concentrated in metal products, non-metallic mineral products, manufacturing of cultur, education, art, sports and entertainment goods, manufacturing of computer, communication and other electric devices, and manufacturing of specialized equipment, accounting for 11.70%, 10.17%, 8.60%, 7.82%, and 4.81%, respectively. A total of 196 enterprises (accounting for 7.39%) reported an average of three or more new cases per year, while 19 enterprises (accounting for 0.72%) reported an average of ten or more cases per year. Conclusion The epidemic status of occupational diseases in Guangdong Province showed a “triple concentration” characteristic in disease types, regions, and industries during the “13th Five-Year Plan” period. Particular attention should be paid to epidemic status of occupational noise-induced deafness, occupational silicosis, occupational chronic benzene poisoning, other occupational pneumoconiosis, and occupational hand-arm vibration disease, and also pay special attention to the prevention and control of occupational diseases in the Pearl River Delta region, cities with “zero reported cases”, manufacturing industry and occupational disease-prone enterprises.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.
