Methods A total of 29 716 occupational health examination cases of dust-exposed workers in Handan City in 2024 were collected through the "Occupational Disease and Health Hazardous Factors Surveillance System" of the Chinese Center for Disease Control and Prevention. The chest radiography Results and pulmonary function Results of dust-exposed workers were analyzed from dimensions such as region，type of dust exposure，industry，enterprise scale，gender，age，and length of service. Results Among 29 716 dust-exposed workers，16 had pneumoconiosis-like change on chest X-rays，with a change rate of 0.05%. Abnormal forced vital capacity（FVC） was found in 1 987 cases，with a detection rate of 6.69%. Abnormal forced expiratory volume in one second（FEV1） was found in 402 cases，with a detection rate of 1.35%. Abnormal FEV1/FVC ratio was found in 198 cases，with a detection rate of 0.67%.The rate of pneumoconiosis-like change was the highest in the central and western regions. The abnormal rates of FVC% and FEV1/FVC% in a certain county and district in the east were both higher than those in other counties and districts（χ2=2 185.237，323.857，both P<0.01）. The abnormal rate of FEV1% in a certain county and district in the south was higher than that in other counties and districts（χ2=641.803，P<0.01）. The rate of pneumoconiosis-like change among workers exposed to coal dust and silica dust was higher than that of workers exposed to other types of dust（χ2=9.186，P<0.05）. The rate of pneumoconiosis-like change in the mining and construction industries was higher than that in other industries（χ2=10.120，P<0.05）. The abnormal rates of FVC%，FEV1% and FEV1/FVC% in small and micro enterprises were all higher than those in large and medium-sized enterprises（χ2=272.515，33.586，16.874，both P<0.01）. Conclusion The chest radiography and pulmonary function Results of dust-exposed workers in Handan City show obvious distribution characteristics in terms of region，type of dust exposure，industry，enterprise scale，gender，age and length of service. Dust control work in key regions and industries should be strengthened，and occupational health monitoring of key populations should be enhanced to protect the health of workers.
Objective To explore the impact of deep emotional labor on occupational burnout among emergency department nurses，and analyze the mediating effects of psychological resilience and cognitive reappraisal，so as to provide empirical evidence for emotional management and occupational burnout intervention in the field of emergency nursing. Methods From September to December 2024，convenience sampling was used to select emergency department nurses from 2 grade-A tertiary hospitals in Anhui Province and 5 grade-A tertiary hospitals in Tianjin Municipality as the research subjects. A general information questionnaire，the emotional labor scale（ELS），Connor-Davidson resilience scale（CD-RISC），emotion regulation questionnaire（ERQ），and Chinese Maslach burnout inventory（CMBI） were used for the survey. Pearson correlation analysis was applied to examine the correlations among the four variables，and AOMS 28.0 was used to construct and test the chain mediation model. Results A total of 443 emergency department nurses were surveyed，with a total score of（11.49±2.74）points for deep emotional labor，（60.77±18.98）points for psychological resilience，（29.67±6.72）points for cognitive reappraisal，and （64.68±19.83）points for occupational burnout.Statistically significant differences in deep emotional labor scores were observed among nurses with different ages，educational backgrounds，working years，employment types，monthly incomes，and night-shift nursing experiences（all P<0.05）. Statistically significant differences in psychological resilience scores were found among nurses with different ages，educational backgrounds，and job positions（all P<0.05）. Statistically significant differences in occupational burnout scores were present among nurses with different ages，employment types，and career plans（all P<0.05）. Occupational burnout was negatively correlated with deep emotional labor，psychological resilience，and cognitive reappraisal（r=-0.363，-0.494，-0.417，all P<0.05）. Mediation effect analysis showed that psychological resilience played a partial mediating role in the relationship between deep emotional labor and occupational burnout，with a mediation effect value of -0.075，accounting for 15.76% of the total effect. The partial mediating effect of cognitive reappraisal in the relationship between deep emotional labor and occupational burnout was not significant，with an effect value of -0.015，accounting for 3.15% of the total effect. Psychological resilience and cognitive reappraisal exerted a chain mediating effect in the relationship between deep emotional labor and occupational burnout，with an effect value of -0.014，accounting for 2.94% of the total effect. Conclusion Emergency department nurses show an above-average level of deep emotional labor，psychological resilience，cognitive reappraisal，and occupational burnout. The chain mediation of psychological resilience and cognitive reappraisal in the effect of deep emotional labor on occupational burnout among emergency department nurses is valid. It is suggested that nursing managers should cultivate nurses' psychological resilience and cognitive reappraisal abilities，enhance their emotional management and stress-coping skills，so as to reduce occupational burnout，improve nursing quality，and promote nurses' professional development.
Objective To apply machine learning to analyze the anxiety status and influencing factors of workers in Guangzhou's automobile manufacturing industry，and provide data reference for improving the physical and mental health status of automobile manufacturing workers and promoting sustainable development of the manufacturing industry. Methods From August 2022 to September 2023，a simple random sampling was used to select 8 sample units in the automobile manufacturing industry of Guangzhou，and a total of 873 front-line workers were surveyed. Respondents were randomly divided into a training group（n=611） and a validation group（n=262） at a ratio of 7∶3，and feature screening was performed using univariate Logistic regression，Boruta regression，Lasso regression and recursive feature elimination（RFE）.Six kinds of machine learning models were established，and the performance of different models was compared by receiver operating characteristic（ROC） area under the curve（AUC），calibration curve and decision curve analysis（DCA）.Shapley additive explanation（SHAP） algorithm was used to evaluate the factors affecting anxiety. Results Among the 873 respondents，284（32.5%） experienced anxiety.After screening for characteristic indicators，eight characteristic variables including gender，marital status，length of employment，nature of the company，level of health and legal knowledge，level of healthy work Methods and behaviors，occupational stress，and sleep status were selected and incorporated into six machine learning models to construct predictive models.Among them，the LightGBM model had the highest AUC of 0.705，while the AUCs of the other five models，from high to low，were 0.683，0.667，0.634，0.630，and 0.601.The LightGBM model also demonstrated greater clinical decision net benefit in the DCA curve，indicating the best overall predictive performance. The SHAP algorithm analysis revealed that having sleep disorders，experiencing occupational stress，working in a foreign-funded enterprise，and having a longer tenure in the current position would increase the risk of anxiety，while high levels of health and legal knowledge and healthy work Methods and behaviors would reduce the risk of anxiety. Conclusion The anxiety of workers in Guangzhou's automotive manufacturing industry warrants attention.Enterprises can mitigate anxiety risks by optimizing job assignments，rest periods，and working conditions，as well as enhancing occupational health education.Additionally，the LightGBM model can be utilized to identify risk factors for anxiety，enabling early intervention.

It aims to provide new ideas for preventing and improving job burnout among anesthesiology nurses and stabilizing the nursing team. Methods From June 2022 to May 2023，a total of 209 anesthesiology nurses working in 5 public hospitals of different levels in Nanjing were selected as research subjects using the convenience sampling method. A survey questionnaire was used to evaluate them，and the data were analyzed. Results Among the 209 anesthesiology nurses，the scores of job burnout，role clarity，perceived stress，and emotional labor were （61.90±4.25），（31.58±3.25），（39.71±3.09） and （55.00±4.35）points，respectively. Job burnout was negatively correlated with role clarity，and significantly positively correlated with perceived stress and emotional labor（r=-0.826，0.863，0.834，all P<0.01）. Role clarity was significantly negatively correlated with perceived stress and emotional labor（r=-0.708，-0.761，both P<0.01）. Perceived stress was significantly positively correlated with emotional labor（r=0.807，P<0.01）. Both perceived stress and emotional labor played a partial mediating role in the relationship between role clarity and job burnout，with effect values of -0.084 and -0.085，accounting for 13.52% and 13.69% of the total effect，respectively. Conclusion The parallel mediation effect of perceived stress and emotional labor between role clarity and job burnout is established，confirming that role clarity can indirectly influence job burnout in anesthesia nurses by moderating perceived stress and emotional labor.
Objective To investigate the relationship between nurses' occupational burnout and workplace psychological violence，and to explore the mediating role of perceived stress，aiming to provide evidence for developing targeted interventions to reduce occupational burnout among clinical nurses. Methods From October 2024 to March 2025，a convenience sampling method was used to select 921 nurses from seven tertiary general hospitals in Sichuan Province as the research subjects. A questionnaire survey was conducted using general demographic characteristics questionnaire，the burnout inventory，workplace psychological violence assessment tools，and the perceived stress scale，and the data were analyzed. Results The mean scores for occupational burnout，workplace psychological violence，and perceived stress among nurses in tertiary general hospitals in Sichuan Province were （41.09±21.87），（18.88±25.93） and （23.21±7.63）points，respectively. Occupational burnout was positively correlated with workplace psychological violence and perceived stress（r=0.529，0.749，both P<0.01）. Workplace psychological violence was positively correlated with perceived stress（r=0.424，P<0.01）. Perceived stress partially mediated the relationship between workplace psychological violence and occupational burnout，with a mediation effect value of 0.261，accounting for 49.90% of the total effect. Conclusion The occupational burnout of nurses in tertiary general hospitals in Sichuan Province is at a moderate level，and perceived stress plays a mediating role between psychological violence and occupational burnout. Nursing administrators can reduce nurses' perceived stress by decreasing workplace psychological violence，thereby alleviating occupational burnout，enhancing job satisfaction and mental health，and promoting the stability and sustainable development of the nursing workforce.

Objective To analyze the characteristics of reported occupational diseases in Qingxiu District of Nanning City from 2006 to 2024，to provide a basis for optimizing the allocation of regional occupational disease diagnostic resources and strengthening cross-regional collaboration in the prevention and treatment of occupational diseases. Methods Occupational disease cases in Qingxiu District from 2006 to 2024 were exported from the Occupational Disease and Health Hazard Factors Monitoring Information System，and the data were collated using WPS Office 2024 software and analyzed with descriptive statistics using SPSS 23.0 software. Results A total of 3 433 cases of 8 categories and 50 types of occupational diseases were reported in Qingxiu District of Nanning from 2006 to 2024. The distribution of the employers of the cases was as follows：3 250 cases（94.67%） in other cities within Guangxi，149 cases（4.34%） in foreign provinces，and 34 cases（0.99%） in Qingxiu District. The top three reported occupational diseases were occupational pneumoconiosis and other respiratory diseases（2 508 cases，73.06%），occupational chemical poisoning（759 cases，22.11%），and occupational ear，nose，throat，and oral diseases（79 cases，2.30%）. Cases were predominantly male（92.46%）. The median length of employment was 9 years，and the median age at onset was 47 years. After reaching a peak in 2009，the number of reported cases showed a fluctuating downward trend. In terms of industry distribution，cases were mainly concentrated in mining（54.18%） and manufacturing（36.64%）. By economic ownership type，private enterprises（44.95%） and state-owned enterprises（32.94%） were the predominant categories. In terms of enterprise size，large and medium-sized enterprises accounted for the majority（59.78%）. Conclusion Occupational disease reports in Qingxiu District were characterized by the separation of diagnosis and exposure，the dominance of traditional occupational disease hazards，the concentration of privately owned and large and medium-sized enterprises，and the high prevalence of middle-aged men. It is recommended to build a provincial collaborative network for occupational disease diagnosis，optimize the allocation of diagnostic resources，strengthen the management of dust and noise，upgrade engineering protection in mining and manufacturing industries，and implement mandatory health monitoring in private enterprises and equipment renewal in state-owned enterprises.
Objective To explore the genetic susceptibility of cysteine aspartate-specific protease-1（CASP1）gene polymorphisms to silicosis in Xinjiang，as well as the loci interaction of nucleic acid binding oligomeric in the pathogenesis of silicosis，and to provide insights into the pathogenesis and prevention of silicosis. Methods By convenient sampling，workers diagnosed with occupational silicosis in a provincial occupational disease diagnosis institution in Xinjiang from January 2020 to December 2024 were selected as the research subjects. A total of 84 patients with occupational silicosis were included as the case group，and 70 workers exposed to silica dust but without pneumoconiosis were included as the control group. The single nucleotide polymorphism loci rs2282659，rs530537，rs516095，and rs1790203 of the CASP1 gene were selected.After blood sample collection，DNA was extracted for genotyping. A non-conditional logistic regression model was applied to analyze the association between genetic polymorphisms and silicosis susceptibility，and generalized multi-factor dimensionality reduction method was used to analyze the correlation of the interaction between polymorphism loci and silicosis. Results The secondary allele frequencies of rs2282659 and rs530537 in the silicosis group were significantly lower than those in the dust-exposed control group（both P<0.05）. After adjusting for confounding factors such as exposure duration，smoking and alcohol consumption，in the dominant model at rs530537，carriers of TC and CC genotypes had lower risk of developing silicosis compared to TT genotype carriers（OR=0.461，95%CI：0.231-0.922，P<0.05）. Under the superdominant model，TC genotype carriers showed reduced risk than TT and CC carriers（OR=0.495，95%CI：0.245-0.999，P<0.05）. In the additive model，the risk of silicosis gradually decreased with increasing C allele frequency（OR=0.541， 95%CI：0.299-0.976，P<0.05），confirming the dominant model as the optimal genetic model. Interactions between GMDR loci revealed that the interaction model involving rs2282659，rs530537，and rs1790203 was the most significant（P<0.05）. Conclusion The CASP1 genes rs530537 and rs2282659 are associated with the risk of silicosis，and there is an interaction with rs1790203，which provides clues for further study of the risk of silicosis.
Objective To establish an inductively coupled plasma mass spectrometry（ICP-MS） method for the simultaneous determination of 20 metal elements in blood，and to detect the metal exposure level of occupational population in the lithium battery dismantling industry. Methods Microwave digestion was employed as sample pretreatment，with digestion in a nitric acid system，acid scavenging，and dilution to a constant volume.

The matrix effect was reduced by internal standard calibration. Results The correlation coefficients（R2） of the linear equations for all 20 metal elements were all greater than 0.996. The detection limits ranged from 0.005 to 0.429 μg/L，and the quantification limits ranged from 0.015 to 1.431 μg/L. The recovery ranged from 85.36% to 109.14%，and the relative standard deviation（RSD） was ≤12.17%. Conclusion The established method is rapid，with good precision and accuracy，and suitable for the simultaneous determination of multiple metal elements in blood.
Objective To analyze the current situation and latent profile of nurses' career compromise from the perspective of psychological contract，and to explore the influencing factors of different categories of nurses' career compromise，so as to provide reference for nursing managers to reduce nurses' professional compromise. Methods From October 2024 to March 2025，this study used the convenience sampling method to select 678 nurses from 4 grade-A tertiary hospitals in Xi'an as the survey subjects. The demographic questionnaire，occupational compromise scale，hospital organizational climate scale and role overload scale were used for the survey，and the data were analyzed. Results The score of career compromise was （43.90±9.36）points，the score of organizational atmosphere was （78.60±13.76）points，and the score of role overload was （16.89±4.26）points. Nurses' level of career compromise was divided into 3 latent classes，namely high compromise-concession（11.1%），medium compromise-adaptation（56.6%），and low compromise-ideal（32.3%）.The Results of univariate analysis showed that education background，professional titles，marital status，shift，average monthly income，age，working years，organizational atmosphere，and role overload all had statistically significant differences in the potential profile category of nurses' career compromise（all P<0.05）. The Results of the multivariate analysis showed that educational background，working years，professional title，organizational atmosphere and role overload contributed to the regression equation model of nurses' career compromise latent profile category（all P<0.05）. Conclusion The overall level of career compromise among nurses in 4 grade-A tertiary hospitals in Xi'an is medium and heterogeneous，which could be divided into 3 latent profiles. Nursing managers should focus on nurses from high compromise-concession group and medium-compromise-adaptive group，and take targeted measures from a psychological contract perspective to improve organizational atmosphere and reduce role overload，thereby stabilizing the nursing team.

Objective To understand the intrinsic mechanisms among perceived organizational support，self-efficacy，and job crafting of emergency department nurses，and to analyze their influencing factors and mediating pathways，so as to provide references for the management of emergency nursing teams. Methods From March to May 2025，a cross-sectional survey was conducted among 397 emergency department nurses from six tertiary hospitals in Beijing，who were selected via convenience sampling. Data were collected using the perceived organizational support scale，the general self-efficacy scale，and the job crafting scale，and were subsequently analyzed. Results The total score M（P25，P75） of perceived organizational support of 397 emergency department nurses was 50.00（41.00，63.00）points，the total score of self-efficacy was 34.00（27.00，40.00）points，and the total score of job remodeling was 74.00（61.00，84.00）points. The perceived organizational support was positively correlated with both self-efficacy and job crafting（r=0.177，0.341，both P<0.01）. A positive correlation was also observed between self-efficacy and job crafting（r=0.289，P<0.01）. The mediating path "perceived organizational support → self-efficacy → job crafting" was established （β=0.044，P<0.05），accounting for 12.90% of the total effect. Conclusion Self-efficacy partially mediates the relationship between perceived organizational support and job crafting. It is recommended that nursing managers could enhance emergency department nurses' job crafting and promote their sustainable career development by adopting a dual-pronged approach focusing on perceived organizational support and individual empowerment. Specifically，this can be achieved through optimizing supportive management strategies and implementing targeted empowerment training，thereby establishing a dynamic "support-empowerment-reshaping" management model.
Objective To understand the status quo of young talents' sense of occupational attainment in public hospitals，analyze the effect of organizational support on young talents' sense of occupational attainment，and construct a scientific and feasible path to improve organizational support. Methods From January to December 2025，420 young talents ≤35 years old in six public hospitals in Tianjin were selected and randomly divided into an intervention group of 210 and a control group of 210. Baseline evaluation of sense of gain was conducted before intervention，and data analysis was completed. The control group adopted the routine talent management mode of the hospital，and the intervention group implemented standardized comprehensive organizational support intervention with career development，emotional care and value identification as the core on this basis. The intervention period was 12 months，with sense of career growth，sense of work value and sense of organizational belonging as the main observation indicators for evaluation，and the data were analyzed. Results There were no statistically significant differences in the total score and sub-dimension baseline scores of career growth，work value and organizational belonging sense of gain between the two groups before intervention（all P>0.05），with balanced baseline comparability. After intervention，the total score of career growth sense of gain in the intervention group[（4.26±0.58）points] was higher than that in the control group[（3.52±0.64）points]（t=12.354，P<0.01）. The total score of sense of work value[（4.31±0.52）points] was higher than that of the control group[（3.48±0.61）points]（t=14.267，P<0.01）. The total score of sense of organizational belonging[（4.40±0.49）points] was higher than that of the control group[（3.55±0.63）points]（t=15.189，P<0.01）. The compliance rate of each dimension in the intervention group （89.52%，91.43%，93.33%） was also significantly higher than that in the control group（62.38%，60.48%，63.81%）（χ2=42.365， 48.721，53.108，all P<0.01）. Conclusion Systematic organizational support can significantly improve the sense of occupational attainment，sense of work value and sense of organizational belonging of young talents in public hospitals. The construction of a multi-level，precise and long-term organizational support system can stabilize the talent team，stimulate endogenous motivation，and promote the high-quality development of public hospitals.

Methods From 2023 to 2024，fifty central air conditioning ventilation systems from public places were tested for hygiene indicators，including supply air，the inner surface of air ducts，and Legionella pneumophila in cooling water，and the data obtained were analyzed. Results The overall qualified rate for the 8 hygiene indicators was 95.6%. The qualified rates for total bacterial count of supply air，total fungal count of supply air，dust accumulation in the inner surface of air ducts，and Legionella pneumophila in cooling water were 72.0%，84.0%，99.2%，and 60.0%，respectively. The remaining indicators（inhalable particulate matter and β-hemolytic Streptococcus in supply air，total bacterial count and total fungal count in the inner surface of air ducts） all reached 100.0%. From the perspective of locations，the overall qualified rate for medical institutions was 96.6%，significantly higher than the 93.9% for non-medical institutions（χ2=3.915，P<0.05）. The qualified rate for Legionella pneumophila in cooling water of medical institutions was 71.9%，significantly higher than the 38.9% for non-medical institutions（χ2=5.223，P<0.05），and the main serogroups of Legionella pneumophila in medical and non-medical institutions were Lp1 and Lp2-14，respectively（P<0.05）. From the perspective of hygiene indicators，there were statistically significant differences among the inhalable particulate matter，total bacterial count，total fungal count，and β-hemolytic Streptococcus in supply air（χ2=28.396，P<0.01）. The total bacterial count in the inner surface of air ducts was positively correlated with dust accumulation and the total fungal count（r=0.491，0.556，both P<0.01），and the total bacterial count of supply air was also positively correlated with the total bacterial count and total fungal count in the inner surface of air ducts（r=0.413，0.316，both P<0.05）. Conclusion The overall hygiene status of central air conditioning ventilation systems in Haidian District of Beijing is satisfactory. However，attention should be paid to bacterial and fungal levels in supply air and Legionella pneumophila in cooling water，enhancing routine cleaning and disinfection.
Objective To explore the influencing path of information literacy on innovation behavior of nursing interns，and to examine the mediating mechanism of scientific research ability between the two，so as to provide a theoretical basis for constructing a collaborative development training system of "information literacy-scientific research ability-innovation behavior". Methods From February 2024 to February 2025，a cross-sectional study design was used to conveniently select 260 nursing interns from a grade-A tertiary hospital in Shanghai，and questionnaires were conducted using the general information questionnaire，the nurses' innovative behavior scale，the nursing staff information literacy self-rating scale and the nurses' scientific research ability self-rating scale. The path relationship between variables was analyzed by structural equation modeling（SEM），and the Bootstrap method was used to test the mediating effect. Results The score of innovative behavior was （27.96±9.50）points，information literacy was （116.10±18.19）points，and scientific research ability was （57.25±24.17）points. Correlation analysis showed that information literacy and scientific research ability were significantly positively correlated with innovative behavior（r=0.322， 0.221，both P<0.01）. Structural equation model analysis showed that the total effect of information literacy on innovation behavior was 0.800（95%CI：0.042-1.860，P<0.05），of which the direct effect was significant（β=0.397，95%CI：0.195-0.585，P<0.01），and the direct effect of scientific research ability on innovation behavior was also significant（β=0.298，95%CI：0.180-0.426，P<0.01）. Scientific research ability played a partial mediating role in the relationship between information literacy and innovation behavior（β=0.118，95%CI：0.054-0.206，P<0.01），and the mediating effect accounted for 14.8% of the total effect. Conclusion Information literacy and scientific research ability are important predictors of innovative behavior，and scientific research ability plays a partial mediating role between them. It is suggested to establish an integrated training system of "information literacy-scientific research ability-innovative behavior" in nursing education，and enhance the innovation ability of interns by strengthening information skills training and scientific research practice.
Objective To investigate the impact of trait self-objectification on online impulsive shopping among female college students，in order to provide theoretical basis for a deeper understanding of the formation mechanism of non-self-disciplined online shopping among female college students. Methods From November to December 2024，a questionnaire survey was conducted on 380 female college students from a university in Guangdong Province to investigate their online impulse buying tendencies and related influencing factors，and the data were analyzed. Results The score of trait self-objectification was （31.80±7.34）points，the score of certainty in control was （25.70±6.84）points，the score of social intuition was （13.44±3.39）points，the score of online impulsive buying was （35.19±9.57）points，and the score of symptom rumination was （22.82±6.52）points. Trait self-objectification could positively predict online impulsive buying（β=0.394，P<0.01）. Certainty in control and social intuition were chain mediators of trait self-objectification affected on online impulsive buying（95%CI：0.010-0.042）. Symptom rumination played a positive role in moderating the relationship between certainty in control and social intuition in the chain mediating path（β=0.15，P<0.01）. Conclusion The trait self-objectification can influence female college students' online impulsive buying through certainty in control and social intuition，while symptom rumination increases the influence of certainty in control on social intuition to a certain extent.Education staff can reduce students' online impulsive purchasing behavior by providing psychological health education，improving interpersonal relationships，and enhancing communication skills
Objective To conduct a latent profile analysis and explore influencing factors of metacognitive abilities among nursing undergraduates using latent profile analysis（LPA）. Methods From August to November 2023，775 nursing undergraduates from 14 universities across 5 provinces/municipalities（Beijing Municipality，Hubei Province，Zhejiang Province，Shanxi Province，and Henan Province） were selected as participants using convenience sampling.General information questionnaire and nursing students' metacognitive ability scale were used to collect demographic data and assess metacognitive abilities.Latent profile analysis determined optimal latent categories，with ordered multinomial Logistic regression analysis identifying influencing factors.Results The metacognitive ability score of 775 nursing undergraduates was （90.83±19.01）points，and their metacognitive abilities could be classified into four latent categories：low-scoring group（12.8%），medium-low group（50.1%），medium-high group（30.5%），and high-scoring group（6.7%）.Ordinal multinomial Logistic regression revealed that attending a ministry-affiliated university（OR=1.950，P<0.05） or a provincial university（OR=1.523，P<0.05） were positive predictors of metacognitive ability. Conversely，being a first-year student（OR=0.466，P<0.01），second-year student（OR=0.605，P<0.05），third-year student（OR=0.654，P<0.05），lack of student leadership experience（OR=0.623，P<0.01），and no exposure to simulation-based teaching（OR=0.550，P<0.01） were negative predictors of metacognitive ability. Conclusion The metacognitive abilities of undergraduate nursing students are heterogeneous，and particular attention should be paid to enhancing the self-awareness dimension.Nursing educators should develop targeted interventions incorporating these determinants to optimize metacognitive development.
Objective To investigate the relationship between rumination and emotional self-care ability of college students， construct a network model and identify potential intervention targets， so as to provide reference for alleviating the psychological problems of college students. Methods From March to June 2024， convenience sampling was used to select 5 527 college students from 3 comprehensive universities in Wuhan of Hubei Province as the research object. The general information questionnaire， ruminative responses scale（RRS）， brief self-control scale（BSCS） and cognitive emotion regulation questionnaire（CERQ） were used to conduct the questionnaire survey. R 4.3.2 software was used for network analysis to explore the strength（S）， expected influence（EI） and bridge strength（BS） of RRS， BSCS and CERQ， and centrality metrics were calculated to identify key nodes. Results The scores of RRS， BSCS and CERQ of college students were （40.64±11.84），（35.12±6.66） and （52.65±11.13）points， respectively. Univariate analysis showed that there were statistically significant differences in RRS， BSCS and CERQ scores among college students with different gender， left-behind experience， father's education level， mother's education level， exercise frequency and participating in emotional management training（all P<0.05）. The centrality index of the concurrent network/bridge network model showed that the node with the highest strength and bridge strength was RRS "symptom rumination"（S=2.228/BS=0.831）. The node with the highest expected impact was CERQ "re-focusing plans"（EI=0.911）. Conclusion Rumination in college students is closely linked to self-control and cognitive emotion regulation strategies."Symptom rumination" and "re-focusing plans" serve as key intervention targets. By developing scientifically precise psychological interventions， improvements in both physical and mental health among college students can be facilitated.
Objective To explore the occurrence and influencing factors of work-related musculoskeletal disorders（WMSDs） among workers in electronic manufacturing enterprises in China by using the Meta-analysis method，and provide a reference for the prevention and treatment of WMSDs in this population. Methods Literature on the occurrence of WMSDs among workers in electronic manufacturing enterprises in China was retrieved from databases such as China National Knowledge Infrastructure （CNKI），Wanfang Data，Chinese Science and Technology Journal Database（VIP），Pubmed，Web of Science，and Cochrane Library. The retrieval period was from the establishment of the databases to May 2025. After screening the relevant literature according to the inclusion and exclusion criteria，the data of the included literature was extracted and analyzed using Stata 12.0 software. Results A total of 20 literatures were included. The Results of the Meta-analysis showed that the prevalence of WMSDs among workers in electronic manufacturing enterprises in China was 44.6%（95%CI：40.7%-48.6%）. The prevalence of single-site WMSDs was 12.3%（95%CI：9.8%-14.8%），and the prevalence of multi-site WMSDs was 34.5%（95%CI：22.0%-47.1%）. The top three prevalence rates of WMSDs in each part of the body were as follows：neck 29.8%，shoulders 25.2%，and hands/wrists 17.8%. Long working years（OR=1.79，95%CI：1.20-2.65），long sitting hours（OR=1.31，95%CI：1.18-1.46），maintaining the same posture for a long time（OR=1.96，95%CI：1.41-2.73），prolonged repetitive actions（OR=1.80，95%CI：1.44-2.25），sufficient rest time （OR=0.58，95%CI：0.47-0.70），taking turns to complete work（OR=0.70，95%CI：0.50-0.98） were the influencing factors for the occurrence of WMSDs. Conclusion The incidence of WMSDs among workers in electronic manufacturing enterprises in China is relatively high，and multi-site WMSDs is more common than single-site WMSDs. Long working years，long-term sitting work，maintaining the same posture for a long time，and long-term repetitive actions are risk factors for the occurrence of WMSDs，while sufficient rest time and taking turns to complete work are protective factors for the occurrence of WMSDS.
Objective To understand and optimize the implementation pathway of orientation education for standardized residency training（SRT），evaluate the feedback effect of residents in Tianjin on the curriculum，and improve the quality and connotation of admission education. Methods A total of 154 enrolled residents who participated in SRT at a hospital in Tianjin in 2025 were selected to receive orientation education，after which they took post-training assessments and completed a program feedback survey. Results The training assessment pass rate for 154 residents was 100.00%，and the satisfaction rate reached 77.92%.The training format that resident physicians found most beneficial was expert theoretical lectures.59.74% of resident physicians suggested that the educational content should be more aligned with practical needs（such as hands-on clinical skill guidance），and 49.35% recommended making the training format more flexible（such as discipline-specific teaching），as well as supplying written and electronic materials. Rank-sum tests were used to compare feedback on satisfaction with orientation education and its helpfulness stratified by specialty and personnel category，the Results revealed statistically significant intergroup differences in satisfaction with orientation education across different personnel types（P<0.05）.Among residents of different specialties，only the dimension of emergency competency training showed no statistically significant difference（P>0.05），while all other evaluation indicators showed statistically significant differences（all P<0.05）. Conclusion Through the construction of a three-dimensional support system of "psychological adaptation-competency cultivation-professional identity" in induction education，the role transformation and competency enhancement of resident physicians can be promoted. Meanwhile，relying on demand-oriented tiered and categorized training，a whole-chain faculty assessment and management system，and a closed-loop improvement mechanism，the continuous optimization of the training system and the synergistic realization of its dual functions can be achieved.
With the acceleration of globalization and the continuous evolution of industrial structures，workers worldwide face increasingly complex occupational hazards，and occupational health protection faces unprecedented challenges. This article reviews the occupational health management models of the United Kingdom，the United States，Germany，Finland，Australia，Japan，South Korea，Singapore，and Sweden，and analyzes them from the perspectives of legal systems，regulatory agencies，and key strategies. The results show that these countries have generally established relatively complete laws and regulations and multi-sectoral management mechanisms，attach importance to the occupational health protection of emerging risks and vulnerable groups，and emphasize the shared responsibility of government，enterprises，and workers. China can learn from these international experiences and establish a prevention-oriented，multi-stakeholder occupational health management system to control the prevalence of occupational diseases.
The threat of airborne pathogens to human health has been highlighted in the context of the frequent occurrence of respiratory pandemics，such as SARS，H1N1 influenza，etc. The characteristics of high airtightness and high population density in the built environment，along with the impact of the ventilation system on the growth and transmission of pathogens，have increased the complexity of pathogen transmission.All these factors pose higher requirements for identification and monitoring technologies. This paper focuses on airborne pathogens and provides a review from three aspects：sources，transmission risks and monitoring technologies，with the aim of improving the ability of early identification and monitoring of pathogens in the built environment，providing a reference for in-depth study of transmission mechanisms，and responding to the spread of unknown diseases caused by novel pathogens.
Toluene and xylene are important organic solvents and diluents，valued for their excellent solubility and widely used in the chemical，paint，electronics，and furniture manufacturing industries. In occupational exposure settings，these compounds can be absorbed into the body through the respiratory tract and skin，leading to multi-system toxicity. This article systematically reviews the associated occupational health hazards and their mechanisms of action. Research indicates that the nervous system is a primary target，with exposure potentially causing headaches，memory loss，and other symptoms of neurasthenic syndrome. The hematological toxicity is particularly notable，which may lead to leukopenia and even aplastic anemia. Direct contact can irritate the respiratory mucosa，cause chronic inflammation，and result in contact dermatitis and skin fissures. Recent studies have further established links between exposure to toluene and xylene and high-frequency hearing loss，reproductive endocrine disruptions，as well as liver and kidney dysfunction. The core mechanisms underlying these toxic effects are widely recognized to involve oxidative stress，inflammatory responses，apoptosis，and aberrant gene expression pathways. By integrating the current evidence，this review aims to provide a theoretical foundation for improving the occupational health surveillance system，optimizing exposure limit standards，and exploring targeted intervention strategies.
Objective In addition to the lifelong physical challenges brought about by the disease，human immunodeficiency virus（HIV）/acquired immune deficiency syndrome（AIDS） patients are more likely to suffer from complex psychosocial pressures such as stigma and discrimination，lack of social support，and stigma，which can easily affect patients' treatment compliance and lead to the decline of patients' quality of life. As an important indicator to measure the prognosis and quality of life of patients，psychosocial adaptation is becoming a key bottleneck affecting disease outcomes and the effectiveness of public health prevention and control. However，the current research on psychosocial adaptation in this group has some problems，such as vague conceptual definition，lack of localized assessment system，and insufficient intervention program. This article aims to review the research status of psychosocial adjustment in HIV/AIDS patients at home and abroad，elaborating on four aspects：concept definition，assessment tools，influencing factors and intervention methods，in order to provide reference for research innovation and system improvement in this field in China，help improve the level of psychosocial adjustment of patients，and promote the optimization of public health prevention and control.
