Objective To explore in depth the generation mechanisms of multi-source noise in industrial production of automobile casting industry and corresponding noise reduction measures，and to evaluate the actual effectiveness of these interventions. Methods From 2020 to 2024，a field survey was conducted to investigate the basic situation and physical characteristics of different noise sources such as blowing，impact，collision，and vibration in the production process of automotive engines. The 8-hour equivalent continuous A-weighted sound pressure levels（L_{EX，8 h}） before and after noise control were measured and compared. Results A total of 36 individuals were enrolled in the study，targeted noise reduction measures were implemented for major noise sources such as blowing，hammering，and impact during casting processes，including low-pressure casting，low-pressure post-treatment，riser cutting，high-pressure deburring，high-pressure mold grinding，and high-pressure heat treatment. These interventions effectively reduced workers' noise exposure levels across different workstations. Compared with pre-intervention levels，the average reductions in L_{EX，8 h} at various workstations were （2.98±0.92），（19.42±0.66），（3.12±0.73），（4.67±0.49），（15.23±0.80），（12.00±0.87），（12.23±0.29），（5.02±0.75），（8.48±0.87） and （19.37±1.00）dB（A），respectively，with statistically significant differences（all P<0.05）. Furthermore，the occupational hazard classification of noise exposure decreased from grade Ⅲ-Ⅱ to grade I-0，significantly reducing the risk of noise exposure. Conclusion The implementation of multidimensional noise reduction technology can significantly reduce the exposure level of multi-source noise in the automotive casting industry，providing effective and scalable practical basis for noise control and occupational health management in similar manufacturing enterprises.

Objective To explore the determinants influencing the utilization of hearing protection device（HPD） among petrochemical workers，and provide theoretical basis for mitigating noise-induced hearing loss（NIHL） and improving auditory health level of workers. Methods In November 2024，a cross-sectional study was conducted using convenience sampling to recruit 887 noise-exposed workers from a petrochemical enterprise in Lanzhou，Gansu Province. A health belief model（HBM）-based questionnaire was administered to collect demographic data（age，gender，work tenure，education level） and HBM constructs（perceived susceptibility，perceived severity，perceived benefits，perceived barriers，cues to action，self-efficacy） regarding HPD usage. Univariate analysis and binary Logistic regression were employed to identify determinants of HPD compliance，with HPD usage as the dependent variable and the aforementioned factors as independent variables. Additionally，a random forest model was constructed to explore the influencing factors of HPD usage and rank variable importance. Results Among the 887 petrochemical workers，437（49.27%） reported consistent use of HPD，while 450（50.73%） were non-compliant. Univariate analysis revealed that there were statistically significant differences in the impact of HPD usage with knowledge of hearing protection，perceived susceptibility，perceived barriers，perceived benefits，self-efficacy，and cues to action（all P<0.05）. The Logistic regression analysis results showed that self-efficacy（OR=2.203，95%CI：1.592-3.050），perceived barriers（OR=1.412，95%CI：1.073-1.859），and perceived susceptibility（OR=1.352，95%CI：1.022-1.789） were independent influencing factors of HPD compliance（all P<0.05），and higher scores in these variables correlated with increased likelihood of HPD utilization. The random forest model further prioritized determinants by variable importance：self-efficacy emerged as the primary predictor，followed by cues to action，perceived susceptibility，and perceived barriers. Conclusion The usage rate of HPD among petrochemical workers is still relatively low，and self-efficacy，perceived susceptibility，and perceived barriers are the main factors affecting the usage rate of HPD. Enterprises should implement targeted health education programs to cultivate and reinforce workers' self-efficacy，perceived susceptibility，and perceived barriers，thereby enhancing health behavior compliance and advancing auditory health outcomes.

Objective The cohort study of nuclear medicine in Chongqing is a combined retrospective and prospective study based on the radiation workers in the medical industry. According to the research protocol of the National Health Effects Study on Nuclear Medicine Radiation Workers conducted by the Institute of Radiation Medicine，Chinese Academy of Medical Sciences，aims to investigate and determine the correlation and attributable risk of radioactive hazard factors on the incidence of non-communicable diseases. Methods As of January 2024，all radiation workers in nuclear medicine（336 individuals） within the jurisdiction of Chongqing were selected as the exposed group，while 350 diagnostic radiology workers from medical institutions with nuclear medicine departments were randomly selected as the control group using a cluster sampling method. Baseline surveys were conducted for all cohort members. Annual effective doses were monitored，including external radiation doses Hp（10） and Hp（0.07），as well as internal radiation doses from I¹³¹. Results The cohort comprised 686 participants，including 336 nuclear medicine workers（48.98%） and 350 diagnostic radiology workers（51.02%）. Educational attainment at bachelor's degree or higher was observed in 464 subjects（67.64%）. There was a statistically significant difference between 16 nuclear medicine personnel（5.16%） with an occupational exposure of >5 mSv/year and 7 control group members（2.50%）（χ²=6.210，P<0.05）. The three predominant chronic non-communicable diseases identified were endocrine disorders 56 cases（8.16%），gastrointestinal diseases 45 cases（6.71%），cardiovascular disorders 30 cases（4.37%）. There was a statistically significant difference between 168 cases in the exposed group（50.00%） with recent-onset nonspecific symptoms and 87 cases in the control group（25.89%）（χ²=4.235，P<0.05）. Conclusion There is a correlation between occupational radiation exposure and specific health risks among nuclear medicine and diagnostic radiation workers in Chongqing. The high incidence of endocrine，digestive，and cardiovascular system diseases among radiation workers deserves attention，which may reflect the potential impact of radiation on multi system chronic diseases.

Objective To understand the type，level and distribution of occupational hazards in the production process of sandblasting workshop of a factory in Shaanxi Province，analyze the rationality of occupational disease prevention and control facilities，identify the critical control points and critical control measures of occupational hazards. Methods According to related national hygienic standards，methods including field occupational health investigation，occupational hazards detection，particle size and morphology analysis and noise spectrum analysis were applied in comprehensive detection and assessment in May 2025.Results The main occupational hazard factors in production process of sandblasting workshop were silica dust and noise.The dust detection results showed that the content of free silicon dioxide in sandblasting workshop was 42.6%，indicating that the dust produced by sandblasting was silica dust. The concentration of silica dust（total dust andrespirable dust） that sandblasting workers exposed were exceeding the standard. The noise detection results showed that the equivalent continuous A-weighted sound pressure level（L_Aeq） in sandblasting workshop reached to 113.5 and 91.8 dB（A），respectively，and sandblasting workers were exposed to a noise level of the normalization of equivalent continuous A-weighted sound pressure level to a nominal 8 h working day（L_{EX，8 h}） of 104.6 dB（A），making it a noise-exceeding position. Conclusion The occupational disease protective facilities installed in the sandblasting workshop of a factory in Shaanxi Province are ineffective，and the hazards of silicon dust and noise generated during the sandblasting process cannot be ignored. Practical and feasible protective measures such as ventilation，dust removal，and noise reduction should be taken to effectively protect critical control points.

Objective To analyze the therapeutic effect and mechanism of sea buckthorn flavonoids on non-alcoholic fatty liver disease（NAFLD） model mice though the sterol regulatory element binding protein-1（SREBP-1） signaling pathway，and demonstrate its safety and reliability. Methods Sixty healthy adult male KM mice were randomly divided into a normal group，a model group，a positive drug group，a low-dose group of sea buckthorn flavonoids，a medium dose group of sea buckthorn flavonoids，and a high-dose group of sea buckthorn flavonoids. A non-alcoholic fatty liver model was established by administering high-fat diet for 12 weeks. The positive drug group was orally administered with bicyclol，while the low，medium，and high dose groups of sea buckthorn flavonoids were orally administered with 100，200 and 300 mg/kg of sea buckthorn flavonoids，respectively. After continuous administration for 5 weeks，the body mass，serum total cholesterol（TC），triglycerides（TG），low-density lipoprotein cholesterol（LDL-C），and high-density lipoprotein cholesterol（HDL-C） of each group of mice were measured，and liver tissue HE staining was performed. The Western blot method was used to detect the gene and protein expression of sterol regulatory element binding protein-1 in the liver tissues of mice in each group. Results The HE staining results showed significant hepatic steatosis，ballooning degeneration，and inflammatory cell infiltration in the liver slices of the model group. However，compared with the model group，the hepatic steatosis，ballooning degeneration，and inflammatory cell infiltration in the low，medium，and high dose groups of sea buckthorn flavonoids were significantly alleviated. From the results of blood lipid indicators，it can be seen that compared with the normal group[（1.36±0.10），（0.50±0.13），（1.54±0.12），（1.90±0.10）mmol/L]，the TC，TG，and LDL-C levels in the model group were significantly increased[（2.03±0.15），（1.73±0.09），（1.73±0.12）mmol/L]，while HDL-C levels were significantly reduced[（1.50±0.11）mmol/L]（all P<0.01）.At the same time，compared with the model group，the TC，TG，and LDL-C indicators of the groups of sea buckthorn flavonoids showed a decreasing trend，while the HDL-C indicators showed an increasing trend，with the high-dose group of sea buckthorn flavonoids showing the most significant trend. The expression level of SREBP-1 protein in the model group mice was 1.30±0.07. Compared with the model group，the expression levels of SREBP-1 protein in the low，medium，and high dose groups of sea buckthorn flavonoids were 1.15±0.07，0.86±0.05 and 0.48±0.07，respectively. The expression of SREBP-1 gene and protein in the liver tissue in mice of the groups of sea buckthorn flavonoids were significantly decreased（all P<0.01）. Conclusion Sea buckthorn flavonoids can alleviate fat accumulation in the liver of high-fat diet induced NAFLD model mice by reducing the expression of SREBP-1 signaling pathway related genes and proteins，and play a role in treating NAFLD.

Objective To understand the distribution and contamination status of pathogenic bacteria in food in Daxing District of Beijing City，and provide a reliable basis for food safety risk monitoring，management and early warning. Methods A total of 919 food samples from 11 categories were collected from 2019 to 2023，and pathogen monitoring was carried out in accordance with the requirements of the Beijing Food Pollution and Harmful Factors Risk Monitoring Work Manual. Results From 2019 to 2023，a total of 919 food samples were monitored，of which 40 samples were detected pathogenic bacteria，with a detection rate of 4.35%. The detection rate of pathogenic bacteria in different types of food showed a statistically significant difference（χ²=105.272，P<0.01）. The food with higher detection rate was raw meat and its products and raw animal aquatic products（seafood and freshwater products）. Among them，the detection rate of salmonella in raw meat and its products was 21.67%，while the detection rate of Vibrio parahaemolyticus in raw animal aquatic products（seafood and freshwater products） was 6.25%. There was statistically significant difference in the detection rate of pathogenic bacteria in different sampling sites（χ²=31.735，P<0.01）. The detection rate of food samples collected in the circulation link was higher than that in the catering link，and the detection rate of farmers' market was the highest，followed by convenience stores/retail stores，supermarkets and restaurants.Among food samples collected across different quarters，the detection rate of pathogenic bacteria was higher in the third and fourth quarters. Conclusion From 2019 to 2023，there are different degrees of pathogenic bacterial contamination in the food in Daxing District of Beijing City，and the pathogenic bacterial contamination in raw meat and its products，animal aquatic products（seafood and freshwater products） and other foods is more serious. It is recommended that relevant departments focus on the hygiene of the above two types of food，continue to strengthen food hygiene supervision，and prevent the occurrence of foodborne diseases.

Objective To understand the current status and potential profiles of stress adaptation among nursing staff，analyze the influencing factors，and provide a basis for developing personalized stress management strategies. Methods Totally 562 qualified nurses were selected by convenience sampling from a tertiary general hospital in Hebei Province from May to August 2024. The research subjects were surveyed using general data questionnaire，stress adaptation scale，organizational support scale and psychological security scale，and the data were analyzed. Results The score of stress adaptation in nurses was （36.56±6.57）points，including three potential profiles：high-level stress adaptation group（36.8%），medium-level stress adaptation group（44.7%），and low-level stress adaptation group（18.5%）. Logistic regression analysis showed that factors such as age，marital status，monthly income，number of night shifts per month，perceived organizational support，and psychological safety were influencing factors of the potential profiles of stress adaptation among nursing staff，and the differences were statistically significant（all P<0.05）. Conclusions The stress adaptability of nurse need to be improved and shows heterogeneity，which can be divided into three potential profiles. The hospitals and nursing managers should pay more attention to nurse who are young，unmarried，with low monthly income and many night shifts.By enhancing their sense of organizational support and psychological security，the stress adaptability can be improved and physical and mental stress can be alleviated.

Objective To analyze the current situation and influencing factors of occupational health literacy of fire rescue personnel in Shenzhen City，and evaluate the effect after the implementation of intervention. Methods A questionnaire survey on occupational health literacy was conducted among front-line fire rescue personnel in Shenzhen City from June to August 2023. The possession rate of occupational health literacy was calculated. The χ² test and multivariate Logistic regression model were used to analyze the influencing factors. Subsequently，497 people were stratified and selected in clusters from the population who participated in the first survey. The short-term intervention was implemented from September to November 2023，and the changes in their literacy possession rate before and after the intervention were compared. Results The possession rate of occupational health literacy among the survey subjects was 72.17%，and the possession rates of each dimension were 41.05% for knowledge，88.10% for attitude，82.78% for behavior，and 19.25% for skills. The higher age（25-<28，28-<33，≥33 years old），higher education level（high school and technical secondary school，junior college，undergraduate and above），never drinking alcohol and persisting in exercise were protective factors for the possession rate of occupational health literacy. After the intervention，the possession rates of occupational health literacy were 71.49% and 80.45% respectively，and the difference was statistically significant（P<0.05）. Conclusions The possession rate of occupational health skills and knowledge literacy among the surveyed subjects is relatively low. The age groups，educational levels，and personal living habits（drinking conditions，exercise conditions） are the influencing factors of their occupational health literacy. The emphasis should be placed on occupational health education for people with lower age and educational level and poorer personal living habits（such as alcohol consumption and exercise）. The short-term intervention can effectively increase the possession rate of occupational health literacy among fire rescue personnel.

Objective To explore the changes in epidemiological characteristics of varicella in Jinnan District after the inclusion of varicella vaccine，live（VarV） in local immunization programs in Tianjin，provide a reference for further optimizing varicella vaccination strategies and prevention and control measures. Methods Using the data from the 2023-2024 period to represent the management phase of the Expanded Programme on Immunization（EPI），and the data from the 2015-2016 period to represent the non-EPI management phase，the descriptive statistics was used to analyze the epidemic characteristics of varicella and the correlation between VarV vaccination rate and incidence rate during the two periods. Results From 2015 to 2024，a total of 5 933 cases of varicella were cumulatively reported in Jinnan District，the ratio of male to female reported cases was 1.27∶1. The average annual reported incidence rate was 69.98/100 000，with an increasing and then decreasing trend. The difference was statistically significant（χ²=649.444，P<0.01），with the lowest at 30.49/100 000 in 2022 and the highest at 109.49/100 000 in 2019. The average annual reported incidence rate in EPI period（63.05/100 000） was lower than that in non-EPI period（70.59/100 000），the difference was statistically significant（χ²=6.817，P<0.01）. The disease incidence in both periods followed a seasonal pattern with two distinct peaks，mainly in winter（November to January of the following year） and Spring（April to May）. Compared to the non-EPI management period，the highest reported incidence rate shifted from 9~<10 years to 15~<20 years in EPI management period. The incidence rates declined across all age groups under 10 years old，with statistically significant differences between two periods observed in all groups except for 8-<9 years. The primary settings for varicella outbreaks transitioned from kindergartens and primary schools to predominantly middle schools and higher educational institutions. For the birth cohorts of 2007-2015，the coverage rate of the first dose of VarV ranged from 76.41% to 90.58%，while the second dose coverage rate ranged from 9.64% to 50.11%. For the birth cohorts of 2016-2023，the coverage rate of the first dose of VarV ranged from 95.27% to 99.46%，and the second dose coverage rate ranged from 85.41% to 98.89%. The 377（born after 2005） cases could be found immunization history accurately in 2024， 55.43% had received one dose of VarV，with an average interval of （12.90±3.38）years from vaccination to disease onset，and 11.41% had received two doses of VarV，with an average interval of （7.67±2.30）years from vaccination to disease onset. Conclusions After the implementation of the two-dose VarV vaccination strategy in the immunization program in Jinnan District of Tianjin，the incidence of varicella among children under 10 years old significantly decreases，with a shift in the age of onset toward older groups. The varicella outbreaks gradually occur more frequently among senior-grade students. The vaccination coverage of the two-dose VarV in the 2016-2023 birth cohort remains at a high level，while the second-dose VarV coverage in the 2007-2015 birth cohort is relatively low.

Objective To investigate the current situation of the level of resilience of operating room nurses，and explore its related factors and the path of action between some of the factors，provide data reference for the management of operating room nurses. Methods From January to June 2024，the convenience sampling method was used to select the operating room nurses of four hospitals in Liaocheng City as the research object. The general information form，work input scale，perceived social support scale and medical staff resilience scale were used to launch the status quo survey. The statistical results were analyzed by using SPSS 25.0 and AMOS 26.0 software. Results The resilience scores of 167 operating room nurses were （68.37±9.97）points，and the scores were （21.84±4.59）points for the decision coping dimension，（15.87±3.02）points for the interpersonal connection dimension，（15.44±3.31）points for the rational thinking dimension，and （15.00±3.31）points for the flexible self-adaptation dimension. There were statistically significant differences in the resilience scores among operating room nurses with different gender，age，education，position，salary，and whether they had received psychological training（all P<0.05）. There were positive correlations between the resilience of operating room nurses and their work commitment，their perceived social support（all P<0.05）. Multiple linear regression analysis showed that gender，salary，position，job involvement，and perceived social support level were influencing factors for the resilience score of operating room nurses（R²=0.593，adjusted R²=0.583，F=56.750，P<0.01）. The structural equation modeling showed that perceived social support partially mediated the relationship between job involvement and resilience，with a mediating effect of 40.04%. Conclusions The level of resilience of nurses in the operating room needs to be further improved，and factors such as gender，salary，position，work commitment and perceived social support may be correlated with the level of resilience of nurses in the operating room. It is recommended that hospital management take active measures to address the relevant factors，especially strengthening nurses' perceived social support ability，in order to enhance their resilience and promote the stable development of the nursing workforce.

Objective To understand the chronic comorbidity conditions and mode of the elderly in the suburbs of Shanghai City，explore the association between chronic comorbid diseases，and provide data support for chronic disease screening，prevention and control and management of chronic disease comorbidity for the elderly residents in the suburbs of Shanghai City. Methods Using the data of free health examination of the elderly over 60 years old in the outer suburbs of Shanghai City in 2024，eight chronic diseases were included，including overweight and obesity，hypertension，hyperglycemia，hyperlipidemia，coronary heart disease，stroke，chronic nephritis and high uric acid.The Apriori algorithm was used to conduct the correlation analysis of comorbidity patterns，to explore the association and strength of association between chronic diseases in the elderly population. Results Among the 18 930 subjects，the prevalence of chronic disease was 81.18% and chronic comorbidity rate was 65.36%.The prevalence of urban residents（70.24%） was higher than that of rural residents（58.29%），and the difference was statistically significant（χ²=288.259，P<0.01）.The prevalence of binary comorbidity was 21.35%，and the top three were overweight and obesity and hypertension（1 025 cases，5.41%），overweight and obesity and hyperlipidemia（1 025 cases，5.41%），hypertension and coronary heart disease（837 cases，4.42%）.The prevalence of ternary comorbidity was 14.57%，and the top three patients were overweight and obesity and hypertension and stroke（1 071 cases，5.66%），overweight and obesity and hyperlipemia and coronary heart disease（712 cases，3.76%），and hypertension and stroke and hyperglycemia（432 cases，2.28%）.The association rule analysis showed that most of the eight chronic diseases included in this study were mostly associated with hypertension and stroke.In order of confidence，the most common binary comorbidity pattern was stroke and hypertension，and the ternary comorbidity pattern was stroke and hypertension and overweight and obesity.The association rules of the elderly population aged 60-<70 and 70-<80 were higher than those of the elderly population aged≥80. The chronic comorbidity of urban elderly residents was more complicated than that of rural elderly residents. Conclusions The situation of chronic diseases and comorbidities among elderly residents in four remote communities in Shanghai City is not optimistic. It is necessary to strengthen the comprehensive management of elderly patients with chronic diseases and comorbidities by family doctors，deepen the work of health self-management groups in various streets and towns，refine the health education and health promotion interventions for the elderly population in various medical systems within our jurisdiction，effectively enhance residents' awareness of chronic diseases and comorbidities，promote healthy behaviors among elderly residents，prolong residents healthy lifespan，and improve the quality of life of elderly patients with chronic diseases and comorbidities.

Objective To assess the pollution level of benzene series in indoor air of public places in Sichuan Province and the potential health risks to employees，so as to provide fundamental data support for the quality management of public sanitation. Methods From 2021 to 2024，four types of public places，namely gyms，hotels，barber shops and beauty salons，were randomly selected in Chengdu City，Deyang City，Mianyang City and Ya'an City of Sichuan Province to monitor the levels of benzene，toluene and xylene in the indoor air of these public places. The exposure levels of three pollutants were analyzed，and the health risk assessment for their practitioners was conducted in accordance with the health risk assessment model recommended in the Technical Guidelines for Environmental Health Risk Assessment of Chemical Substances（WS/T 777-2021）. Results From 2021 to 2024，a total of 2 545 benzene series samples were detected，the detection rates of benzene，toluene and xylene were 45.30%，47.78% and 49.00%，respectively，and the qualified rates were 98.98%，99.69% and 99.61%，respectively. The differences in the concentrations of benzene，toluene，and xylene were statistically significant（H=69.343，35.645，133.299，all P<0.01），and the pollution level of benzene was the highest in 2021. The median（M） detection concentrations of benzene，toluene，and xylene were 0.085，2.290 and 8.600 μg/m³，respectively，and their chronic non-carcinogenic hazard quotient（HQ） were 8.75×10^-4，1.41×10^-4，2.66×10^-2，respectively. The carcinogenic risk（CR） of benzene was 8.77×10^-8. There were significant differences in the concentrations of toluene and xylene among different places（H=19.729，16.869，both P<0.01）.The pollution levels of toluene in gyms and beauty shops were higher，with the median detection concentration of 2.000 μg/m³，and the HQ was 1.24×10^-4. The highest contamination level of xylene was found in beauty shops，with a median concentration of 4.000 μg/m³，and HQ was 1.23×10^-2. There were significant differences in the concentrations of toluene and xylene among different seasons（Z=-5.521，-9.090，both P<0.01）. The concentration of xylene in winter was higher than that in other seasons，with a median concentration of 0.100 μg/m³，and its HQ was 3.09×10^-4.The cumulative probability distribution of health risks showed that the cumulative percentages of benzene，toluene and xylene HQ less than 1 were 98.86%，100.00% and 99.88%，respectively. The cumulative percentage of benzene CR below 10^-6 was 59.02%，the cumulative percentage between 10^-6 and 10^-4 was 39.84%，and there was a maximum value of 1.14% greater than 10^-4. Conclusion The overall qualified rate of benzene series in indoor air of public places in Sichuan Province is high，and the non-carcinogenic and carcinogenic risks of benzene series in indoor air of some places are high，which has a certain health risk to employees，and attention should be paid to it.

Objective To explore the relationship between grit and job search behavior among university graduates，as well as the mechanisms through which career and talent development self-efficacy and school career support influence this relationship.Methods From November to December 2024，a questionnaire survey was conducted among fresh graduates with a bachelor's degree from a university in Fujian Province using instruments including a general demographic questionnaire，grit scale，career and talent development self-efficacy scale，school career support scale，and the job search behavior scale. Results The average score of grit among university graduates was （3.24±0.43）points，the average score of school career support was （3.46±0.73）points，the average score of career and talent development self-efficacy was （4.59±0.81）points，and the average score of job search behavior was （3.31±0.68）points. The grit was significantly positively correlated with both career and talent development self-efficacy （r=0.515，P<0.05） and job search behavior（r=0.303，P<0.05） among university graduates，and the career and talent development self-efficacy was significantly positively correlated with job search behavior（r=0.496，P<0.05）.The mediation effect model test indicated that the career and talent development self-efficacy fully mediated the relationship between grit and job search behavior，with the effect of 0.233.The moderated mediation model revealed that the interaction of grit and school career support significantly negatively predicted career and talent development self-efficacy（β=-0.067，P<0.05），which in turn influenced the job search behavior of university graduates. Conclusion The grit influences the job search behavior of university graduates by enhancing their career and talent development self-efficacy.This effect is particularly pronounced when school career support is relatively lower，as grit more significantly predicts career and talent development self-efficacy，which in turn impacts the job search behavior of university graduates. The university graduates should pay attention to developing their grit qualities，accumulate energy from within，and thus form proactive and effective job seeking strategies.

Objective To analyze the current status，hotspots，and trends of research on nurses' work-family conflict at home and abroad，and to provide references for subsequent related research and clinical intervention. Methods The relevant literature on nurses' work-family conflict published in the CNKI，Wanfang，VIP，China Biomedical Literature Database，PubMed，and Web of Science Core Collection since the establishment of these databases until November 19，2024 was retrieved.CiteSpace 6.4.R1 software was used for bibliometric analysis. Results A total of 809 relevant articles were included，including 465 English-language articles and 344 Chinese-language articles. The literature analysis results showed that the overall publication volume of relevant literature at home and abroad was on the rise，reaching its peak at 42 articles in 2022 and 57 articles in 2024，respectively. The domestic and international research hotspots mainly focus on adverse effects of work-family conflict on nurses' occupational burnout，turnover intention，job satisfaction，work attitude，work engagement and occupational health，the influencing factors of nurses' work-family in work，personal and social levels，and intervention strategies to improve working environment and enhance nurses' psychological coping abilities. Future research trends in this field was in depth analysis of the heterogeneity of work-family conflicts and their influencing factors among nurses in different departments and life stages，and development of targeted intervention strategies. Conclusions Under the current two-child and three-child policies，the nurses' work-family conflict is becoming increasingly prominent，and the attention to related research has increased，but the current research on nurses' work-family conflict is not deep and comprehensive enough.Given the significant negative impact on nurses' individual physical and mental health，career development，and nursing quality，nursing researchers and managers should attach great importance to this issue and conduct in-depth research on related aspects，especially targeted intervention scheme research.

Objective To understand the factors influencing the public health inspection and testing services provided by laboratories in Centers for Disease Control and Prevention（CDC） to the society，and to provide a reference for the formulation of high-quality development strategies for CDC systems. Methods From March to June 2024，a questionnaire survey was conducted on 111 CDCs in Xinjiang Uygur Autonomous Region from the perspective of social services，and the data were analyzed. Results The average self-evaluation score of the inspection and testing capabilities provided by the Xinjiang CDCs to the society was （5.50±2.82）points，with a score rate of 45.8%. The score rate for "average time to issue inspection and testing reports" was the highest，at 71.0%，while the score rate for "the current number of inspection and testing projects being carried out" was low，at 26.0%. The factors affecting the ability of the public health inspection and testing services to the society were mainly the number of testing persons（2-<5 people）（t=-4.101，P<0.01），the laboratory area（500-<1 500 m²）（t=-4.294，P<0.01），and the number of qualified items（0-<50 items）（t=-3.920，P<0.01）. Conclusion The social oriented inspection and testing capabilities of the CDCs in Xinjiang need to be further improved，with relatively good inspection capabilities at the provincial level and some prefecture. However，most county/municipal CDCs still have shortcomings. The number of laboratory inspection and testing personnel，laboratory area，and the number of qualified items are the main influencing factors，and targeted measures need to be formulated to improve and enhance them.

Objective To understand the capabilities，training needs，and effectiveness of doctors and nurses in pneumoconiosis rehabilitation stations in Hunan Province，and to provide a reference for establishing and improve the long-term operation mechanism of rehabilitation stations，continuously enhancing the operation management and service work of rehabilitation stations，and improving the quality of medical services in rehabilitation stations. Methods In November 2023，after the completion of the training program for medical staff in pneumoconiosis rehabilitation stations in Hunan Province，a self-designed questionnaire was used to conduct a survey among all participants via Wenjuanxing，and the data were analyzed. Results A total of 186 medical staff from 107 pneumoconiosis rehabilitation stations participated in the survey. The majority of the staff who attended the training were aged between 20 and 40 years（68.28%），indicating a relatively young workforce. Among them，175 individuals（94.09%） had a college degree or higher. Over 60% of the rehabilitation stations and their medical staff were able to perform 10 or more pulmonary rehabilitation techniques，although most of these techniques were still basic. After the establishment of the rehabilitation stations，the knowledge of pneumoconiosis and pulmonary rehabilitation among the staff improved，with all knowledge scores increasing significantly after the training（all P<0.01）. The most anticipated training methods were case analysis and on-site demonstrations，accounting for 69.35% and 89.25%，respectively. 82.26% of the medical staff expressed a desire for further training in pneumoconiosis pulmonary rehabilitation techniques. Conclusion The construction of pneumoconiosis rehabilitation stations in Hunan Province and the training of their staff have achieved certain results，with overall satisfaction among the trainees. Currently，the pulmonary rehabilitation techniques conducted in most rehabilitation stations are relatively basic，and many techniques have not been well popularized and applied. It is necessary to strengthen training and learning through various methods，implement standardized training regularly，and comprehensively enhance professional capabilities.

In closed work environments，personnel who spend extended periods in spaces lacking natural light are exposed to monotonous and insufficient illumination，which can easily lead to circadian rhythm disruption，low mood，reduced alertness，and impaired cognitive function. The intrinsically photosensitive retinal ganglion cells（ipRGCs） in the retina can detect environmental lighting information，generate non visual effects，and regulate the body's biological clock，mood，and cognitive state. With the development of virtual reality（VR） technology，the integration of lighting and VR creates virtual lighting environments. In such virtual lighting environments，illumination parameters can be precisely controlled to recreate lighting scenes that are consistent with real world settings and provide a strong sense of presence，delivering physiological effects similar to those of natural light. Appropriate virtual lighting can significantly improve users' emotional state，enhance alertness，and promote cognitive performance，offering a health intervention solution for personnel working in long term closed environments.This paper reviews the negative impact of enclosed environments on emotions and cognition，the pathways of non-visual effects of lighting，the overview of virtual lighting，and the application prospects of virtual lighting，providing new perspectives and inspiration for further research on the combination of lighting and virtual reality technology.

Since the transformation of the modern medical model in the 1970s，occupational stress has emerged as a key psychological stressor and become a research focus in academic circles. As the frontline group responsible for treating critically ill patients，prehospital emergency physicians have become a high-risk group for occupational stress due to their professional characteristics，such as a fast-paced work environment，frequent emergencies，and complex doctor-patient relationships. High levels of occupational stress not only undermine the physical and mental health of this group but also may impair the efficiency and safety of medical care，increasing the risk of medical errors. Based on this，this paper systematically collates relevant domestic and international literature，reviews the current research status of occupational stress among prehospital emergency physicians from four perspectives：assessment methods，influencing factors，potential hazards，and intervention strategies，and further explores future research directions. It aims to provide a theoretical reference for alleviating occupational stress among prehospital emergency physicians and ensuring the quality of medical services，while laying a foundation for subsequent research in this field.
