Objective To analyze the prevalence and influencing factors of localized work fatigue after continuous work among laborers in the metal products industry in Qingpu District of Shanghai City. Methods Data were collected from the work-related diseases surveillance questionnaire of key industries in Qingpu District of Shanghai City，and a total of 522 valid questionnaires were collected，including 359 males（68.77%） and 163 females（31.23%）. Binary Logistic regression was conducted to explore the influencing factors. Results The incidence of localized work fatigue after continuous work among laborers was 51.7%. Logistic regression analysis revealed that workers with higher educational level and longer cumulative rest duration had a lower risk of localized work fatigue. For each unit increase，the risk of localized fatigue decreased by 0.628 times（95%CI：0.465-0.850） and 0.694 times（95%CI：0.504-0.957），respectively.Workers with poor physical condition，history of trauma，or musculoskeletal pain had a significantly higher risk of localized fatigue，with odds ratios of 2.650（95%CI：1.709-4.108），3.321（95%CI：1.087-10.146），and 5.834（95%CI：3.225-10.553），respectively，compared to those without these conditions. Laborers who had a higher frequency of physical exercise after work and more frequent upper limb or hand force demand at work were at a higher risk of localized work fatigue. For each unit increase，the risk of localized fatigue increased by 1.403 times（95%CI：1.015-1.940） and 1.361 times（95%CI：1.080-1.716），respectively. Working in an uncomfortable posture，sufficient rest time，and continued working after rest were factors that increased risks of localized work fatigue，with odds ratios of 4.327（95%CI：1.817-10.302），0.461（95%CI：0.283-0.750），and 3.358（95%CI：1.586-7.112），respectively，compared to workers who did not have these conditions. Besides，laborers engaged in three-shift work had a higher risk of localized work fatigue[4.211 times（95%CI：1.866-9.503）] compared to those who did not work in shifts. Conclusion Enterprise managers can alleviate the occurrence of localized fatigue of workers，thus improve production efficiency and quality by enhancing the working environment，optimizing work processes，and providing appropriate rest time.
Objective To analyze lung function and hematological parameter changes in patients with silicosis at different stages，and their relationship with interleukin-1β（IL-1β） and interleukin-18（IL-18） levels，and to understand the application value of a biomarker evaluation system based on principal component analysis in the staging assessment of silicosis. Methods A cross-sectional study was conducted involving occupational dust-exposed individuals，including coal mine administrative staff，undiagnosed dust-exposed subjects，and patients with stage I-III silicosis，who underwent occupational health examinations and treatment at a hospital in Xinjiang from January 2020 to December 2024. Forced vital capacity（FVC），forced expiratory volume in one second（FEV1），and routine hematological parameters were measured. Serum IL-1β and IL-18 levels were determined using enzyme-linked immunosorbent assay（ELISA）.The Jonckheere-Terpstra trend test was applied to analyze parameter trends，while Spearman correlation analysis was used to assess associations between inflammatory cytokines and pulmonary function indices. Principal component analysis（PCA） was employed to construct a multidimensional biomarker evaluation model. Results As the disease progressed，pulmonary function indicators of patients showed a progressive decline，with FVC decreasing by 41.6%（P<0.01）；Serum inflammatory cytokines increased markedly，with IL-1β rising from 0.15 pg/mL in control group to 7.28 pg/mL in stage III silicosis（a 48.5-fold increase） and IL-18 increasing from 136.89 pg/mL to 1187.39 pg/mL（an 8.7-fold increase），with JT values of 8929 and 6744.5，respectively（both P<0.01）；In hematological parameters，while lymphocyte percentage declined from 32.98% to 24.4%（P<0.05）.Correlation analysis revealed that IL-1β was significantly negatively correlated with FVC（ρ=-0.192，P<0.01）. PCA extracted three principal components with a cumulative variance contribution of 97.38%，where principal component 1（PC1） primarily reflected the intensity of inflammatory responses，and principal component 2（PC2） represented the functional status of the hematopoietic system. Conclusion Pulmonary function in patients with silicosis exhibits stage-specific decline，while hematological findings indicate an enhanced inflammatory response. Serum IL-1β and IL-18 levels are closely associated with disease severity and show significant negative correlations with pulmonary function impairment. The multidimensional biomarker evaluation system based on PCA integrates inflammatory markers，hematological parameters，and pulmonary function indices，offering a novel tool for staging assessment and individualized monitoring of silicosis.
Objective To analyze the prevalence，distribution characteristics，and influencing factors of work-related musculoskeletal disorders（WMSDs） among workers in gold and jewelry manufacturing enterprises，thereby providing evidence for the prevention and control of WMSDs. Methods A convenient sampling method was adopted to select 293 workers from gold and jewelry manufacturing enterprises in Shenzhen as study subjects in October 2024. The revised musculoskeletal disorders questionnaire was used to assess the prevalence of WMSDs in different body regions over the past year，and the data were analyzed. Results The overall prevalence of WMSDs among workers was ranked in descending order：neck（49.8%，146/293），shoulder（45.7%，134/293），lower back（44.0%，129/293），upper back（29.4%，86/293），wrist（25.3%，74/293），hip/thigh（14.0%，41/293），elbow（13.3%，39/293），knee/lower leg（11.9%，35/293），and ankle（10.6%，31/293）. Higher prevalence rates of WMSDs were observed for specific positions：shoulder WMSDs in chain weaving positions（70.6%） and polishing positions（63.6%），upper back WMSDs in polishing positions（63.6%），lower back WMSDs in sandblasting positions（75.0%） and chain weaving positions（70.6%），and wrist WMSDs in chain weaving positions（50.0%）. The influencing factors for the occurrence of WMSDs in the neck include sufficient rest time（OR=0.401，P<0.01） and regular exercise（≥20 minutes each time）（OR=0.704，P<0.05）；The influencing factors for WMSDs in the shoulders include repetitive daily tasks（OR=2.123，P<0.05） and job rotation with coworkers（OR=0.569，P<0.05）；The influencing factors for WMSDs in the lower back include repetitive tasks（OR=2.573，P<0.05），sufficient rest time（OR=0.513，P<0.05），and adjustable workstation height（OR=0.449，P<0.05）. Conclusion The incidence of WMSDs among workers in gold and jewellery manufacturing enterprises was relatively high，and WMSDs occur in different regions of the body in different positions. Neck，shoulder and lumbar regions are more common among workers and the main factors affecting the occurrence of WMSDs are regular exercise，ergonomic factors（adjustable table height） and work organization.
Objective To investigate the leader subordinate matching，psychological capital，and occupational burnout status of nurses in the disinfection supply room，and to explore the mediating role of psychological capital between leader subordinate matching and occupational burnout，in order to provide reference for reducing nurses' job burnout. Methods Convenience sampling was used to select 186 nurses from the disinfection supply rooms（supply centers） of 7 comprehensive hospitals in Wuwei City from January to February 2025 as survey subjects，general situation survey，leader subordinate matching survey，psychological capital survey，and occupational burnout survey were conducted，and the data were analyzed. Results The scores for leader subordinate matching，psychological capital，and occupational burnout among nurses in the disinfection supply room were （19.25±4.72），（89.23±16.28），and （60.34±11.56）points，respectively. The comparison of occupational burnout scores among disinfection supply room nurses of different ages，technical title，work experience，and monthly income showed statistically significant differences（all P<0.05）. The leader subordinate matching and psychological capital of disinfection supply room nurses were negatively correlated with occupational burnout（r=-0.498，-0.614，both P<0.01）.The leader subordinate matching was positively correlated with psychological capital （r=0.582，P<0.01）.Leader subordinate matching and psychological capital could jointly explain 37.7% of the variation in occupational burnout among nurses in the disinfection supply room. Psychological capital partially mediated the relationship between leader subordinate matching and occupational burnout，with an effect value of -0.266，and the indirect effect accounts for 44.78% of the total effect. Conclusion The occupational burnout of nurses in the disinfection supply room of seven comprehensive hospitals in Wuwei City is at a high level，and leader subordinate matching can directly predict occupational burnout，with psychological capital playing a mediating role between the two. Nursing managers can help disinfection supply room nurses improve their psychological capital and leadership subordinate matching level through intervention measures，thereby reducing their level of occupational burnout.
Objective To understand the differences of common serum biomarkers between patients with silicosis and healthy populations，analyze the relationship between relevant indicators and the occurrence and development of silicosis，and evaluate their clinical value as potential diagnostic biomarkers for silicosis. Methods Clinical data were collected from hospitalized male patients clinically diagnosed with silicosis at Dazhou Central Hospital from January 2015 to December 2022. A total of 499 male silicosis patients with complete medical records were selected as the observation group，while age-matched healthy males undergoing physical examinations served as the control group，and the data were analyzed. Results The M（P25，P75） of direct bilirubin[3.3（2.4，4.6）umol/L]，creatinine[75.6（66.0，87.0）umol/L]，urea[6.2（4.9，7.9）umol/L]，neutrophil-to-lymphocyte ratio（NLR）[3.4（2.4，5.3）]，and platelet-to-lymphocyte ratio（PLR）[126.3（86.2，182.6）] in the observation group were higher than those in the control group，while hemoglobin[134.0（122.0，145.0）g/L] was lower than in the control group，and the differences were all statistically significant（all P<0.05）. Except for the urea index，the differences in other indicators were statistically significant （all P<0.05），indicating that they were meaningful predictors of silicosis. Bivariate correlation analysis indicated that hemoglobin was negatively correlated with the prediction of silicosis（r=-0.292，P<0.05），while direct bilirubin，creatinine，PLR，and NLR（r=0.139，0.113，0.281，0.264，all P<0.05） were all positively correlated with the prediction of silicosis. The receiver operating characteristic（ROC） curve showed that the area under the curve（AUC） for NLR was 0.733，with specificity of 0.740 and sensitivity of 0.630.The AUC for PLR was 0.731，with specificity of 0.591 and sensitivity of 0.775. The AUC for direct bilirubin was 3.690，with specificity of 0.812 and sensitivity of 0.402. The AUC for creatinine was 0.592，with sensitivity of 0.334 and specificity of 0.818；The AUC for hemoglobin was 0.288，with specificity of 0.994 and sensitivity of 0.012. The AUC for the combined detection of the above significant indicators was 0.862，with specificity of 0.929 and sensitivity of 0.667. The combined detection of these indicators showed significantly higher predictive efficacy for silicosis than any single test alone. Conclusion Elevated levels of bilirubin，urea，creatinine，and blood cell counts in the serum of silicosis patients may serve as potential biomarkers for diagnosing silicosis. The combined detection of bilirubin，creatinine，and blood cell indices can improve the predictive efficacy for silicosis.

Results The average sleep quality score of clinical nurses was （7.89±4.27）points，and a total of 701 nurses had sleep disorders in this study，and the incidence of sleep disorders was 49.75%. The results of multiple linear regression showed that the health status（β=0.150，t=5.143，P<0.01），anxiety（β=0.201，t=6.131，P<0.01），and depression levels of nurses at the personal trait level（β=0.182，t=5.640，P<0.01），the number of children at the interpersonal network level（β=-0.107，t=-2.742，P<0.01），the number of overtime hours in the past month（β=-0.056，t=-1.986，P<0.05），the number of training sessions after night shifts（β=0.054，t=2.003，P<0.05），the level of dual work pressure（β=0.190，t=6.400，P<0.01），and the perception of cooperation with department doctors（β=-0.073，t=-2.259，P<0.05） were the main influencing factors on the sleep quality of clinical nurses. Conclusion The sleep quality of clinical nurses in a grade-A tertiary hospitals in shanghai is poor and influenced by multiple factors. Nursing managers should pay attention to the physical and mental health level of clinical nurses，fully mobilize resources from all aspects to improve the sleep quality of nurses，and promote the stable development of the nursing industry.
Objective To evaluate the differences in serum krebs von den lungen-6（KL-6） levels in middle-aged and elderly patients with interstitial lung disease（ILD） according to different age groups and smoking statuses，and to explore its application value in clinic. Methods A total of 132 ILD patients aged ≥45 years treated at a hospital in Tianjin from January to June 2024 were enrolled. The patients were divided into the middle-aged group（n=36），pre-elderly group（n=63），elderly group（n=33），as well as smoking/non-smoking groups. Clinical data and serum KL-6 levels were collected for statistical analysis. Results The Lg（KL-6） levels in the middle-aged group，pre-elderly group and elderly group were 2.82±0.41，2.98±0.28 and 3.07±0.30，respectively. There was a statistically significant difference in Lg（KL-6） levels among the three age groups（P<0.05）. Further pairwise comparisons showed that the Lg（KL-6） levels in the elderly group were significantly higher than those in the middle-aged group，while no statistically significant difference was observed between the elderly group and the pre-elderly group. The Lg（KL-6） level in the smoking group was significantly higher than that in the non-smoking group（P<0.05）.Multivariate linear regression analysis showed that smoking history（B=0.208，β=0.294，P<0.01） and age（B=0.012，β=0.377，P<0.01） were significantly positively correlated with Lg（KL-6）. Conclusion Serum KL-6 levels in middle-aged and elderly ILD patients are affected by age and smoking status，with higher levels observed in elderly patients and those with a smoking history. This suggests that KL-6 has potential clinical value in reflecting the severity of the disease.
Objective To analyze the surveillance data of influenza-like illness（ILI） in Zigong City from 2016 to 2024，investigate the correlation between ILI cases and meteorological factors，construct an influenza prediction model，and provide a reference point for influenza prevention and control. Methods ILI data and meteorological data reported by national influenza sentinel surveillance hospitals in Zigong City from 2016 to 2024 were analyzed. Spearman rank correlation was used to assess the relationship between ILI and the influenza-like illness percentage（ILI%）. The seasonal autoregressive integrated moving average（SARIMA） model was applied to predict ILI% in Zigong City. Results From 2016 to 2024，174 189 ILI cases were reported by national influenza surveillance sentinel hospitals in Zigong City，with an ILI% of 4.72%. Among 10 920 ILI specimens collected，the positive rate was 20.12%. Dominant strains varied annually（χ2=1 737.32，P<0.05）.A positive correlation was observed between ILI and ILI%（r=0.89，P<0.05）. ILI% was positively correlated with average temperature（r=0.136，P<0.05），and negatively correlated with average air pressure（r=-0.125，P<0.05） and relative humidity（r=-0.129，P<0.05）. The SARIMA model predicted a declining influenza trend in Zigong City during the first half of 2025，aligning with historical epidemic patterns. Conclusion From 2016 to 2024，ILI surveillance in Zigong City revealed a fluctuating upward trend，and dominant strains of influenza A（H1N1），H3N2，and influenza B（Victoria lineage） alternated in prevalence. Meteorological factors are associated with influenza incidence，and the SARIMA model demonstrates robust predictive capability for ILI.
Objective To investigate the current status of psychological abuse and adverse childhood experiences among rural older adults in Hebei Province and analyze the correlation between psychological abuse and adverse childhood experiences of rural older adults. Methods From August to October 2024，a survey was conducted on 352 rural older adults in Hebei Province by a general information questionnaire，adverse childhood experiences scale（ACES），and family psychological abuse assessment scale，and the data were analyzed. Results Among 352 rural older adults，the total score of psychological abuse was （30.43±7.10）points.Correlation analysis showed that the ACES of rural older adults was positively correlated with psychological abuse（r=0.527，P<0.01）. Marital status，disability status，number of chronic diseases，number of medicine use，life satisfaction，social frequency and adverse childhood experiences were all the main influencing factors of psychological abuse among rural older adults（all P<0.05）. Conclusion The degree of psychological abuse experienced by elderly residents in rural Hebei Province was closely related to their childhood adverse experiences. In the future，community health workers could develop targeted intervention plans for rural elderly individuals by leveraging differentiated demographic characteristic and their adverse childhood experiences to minimize the impact of childhood adverse experiences and the risk of psychological abuse among rural elderly.
Objective To analyze the trend of disability-adjusted life years（DALYs） due to occupational noise-induced hearing loss in China from 2007 to 2021，providing data support for the next steps in occupational noise damage prevention and control. Methods Data on the age-standardized prevalence and DALY rates for hearing loss attributed to occupational noise among people aged 20 to 64 were obtained from the Global Burden of Disease（GBD） 2021 database for both global and Chinese populations. The estimated annual percentage change（EAPC） and its 95% confidence interval（CI） were calculated to assess trends in the disease burden. The Bayesian age-period-cohort（BAPC） model was used to analyze changes in age-standardized DALYs and to forecast disease trends from 2020 to 2030. Results From 2007 to 2021，the age-standardized prevalence of hearing loss attributed to occupational noise in China increased from 24 471.01 per 100 000 population to 25 252.67 per 100 000 population（EAPC= 0.258%，P<0.05）. The age-standardized DALY rate also rose from 561.24 per 100，000 to 582.15 per 100，000（EAPC=0.326%，P<0.05），with a growth rate higher than the global average. The BAPC model indicated that the risk of occupational noise-induced hearing loss in China increased with age from 2007 to 2021，with females experiencing a higher risk than males. Notably，the DALYs rates were significantly higher among those aged 20-<25 and 30-<40 years. Although the period-cohort trend showed a general decline，individuals born between 1947 and 1951 faced the highest disease risk，with relative risk（RR） values of 2.062（95%CI：1.703-2.496） for men and 1.848（95%CI：1.489-2.294） for women. However，disease burden projections still indicate a rising trend through 2030. Conclusion Since 2007，China has made significant progress in the prevention and control of occupational noise-induced hearing loss. However，young adults aged 20-<25 and 30-<40 remain high-risk groups requiring continued attention and protection. Future efforts should focus on collaborative prevention strategies across government，enterprises，and healthcare institutions to further reduce the burden of occupational noise-induced hearing loss.
Objective To investigate the current state of work engagement among oncology nurses in grade-A tertiary hospitals，and to analyze the correlation between psychological capital，organizational silence and work engagement，with a view to providing references for administrators to formulate interventions to enhance nurses' work engagement. Methods From February to March 2025，a convenience sampling method was used to select 408 oncology nurses from seven grade-A tertiary hospitals across three provinces/cities in China. The survey was conducted using a general information questionnaire，the shortened version of the work engagement scale，the psychological capital questionnaire，and the nurse organization silence assessment questionnaire，and the data were analyzed. Results Among 408 oncology nurses，the total scores of work engagement，psychological capital，and organizational silence were （35.54±8.83），（108.10±16.96） and （51.60±17.30）points，respectively. Work engagement was positively correlated with psychological capital（r=0.730，P<0.01），and negatively correlated with organizational silence（r=-0.207，P<0.01）. Professional title，psychological capital，and organizational silence were identified as the primary influencing factors of work engagement（all P<0.05），collectively explaining 55.9% of the total variance. Psychological capital played a partial mediating role between organizational silence and work engagement，accounting for 53.221% of the total mediating effect. Conclusion The work engagement of 408 oncology nurses in grade-A tertiary hospitals is at a moderate level. Professional title，psychological capital，and organizational silence significantly influence work engagement. Nursing administrators should optimize the professional title promotion system，cultivate psychological capital，and reduce organizational silence to enhance oncology nurses' work engagement.

Objective To evaluate the phased input and output results of talent cultivation program，analyze the implementation effect and problems，and explore the talent cultivation path and evaluation support system that conforms to the modern centers for disease control and prevention（CDC） system. Methods Fifty middle-aged and young talents selected into the "Talent Team Cultivation" program were chosen as the research subjects.A retrospective investigation was adopted to collect the basic information of the research subjects，the input-output of the first year and the assessment results，and descriptive statistical analysis and non-parametric tests were used to analyze them. Results During the first year of training，the input-output ratios of funds for the three tiers of talents were 2.20，0.20，and 0.55，respectively，and the differences were statistically significant（χ2=12.374，P<0.01）.For output，approved funds，academic output and professional output showed different trends. Among the approved funds and academic outputs，the output of high tier levels，high professional titles and high academic qualifications were relatively high（χ2=12.374，20.095，14.448，Z=-2.568，all P<0.05），while there was no such characteristic among different specialties. Among the professional outputs，the outputs of public health，disease control，and laboratory detection showed a trend from high to low（χ2=9.109，P<0.05），but there were no such trend in terms of different echelon levels，professional titles，and educational qualifications. Conclusion The "Talent Team Cultivation" program conforms to the high-quality development needs of the CDC，and should set up a differentiated multilevel talent cultivation model. At present，there are difficulties in quantifying the professional competence of talent in CDC. Establish an objective evaluation index system and expert review of characteristic work achievements are feasible and reasonable way to evaluate the CDC's professional competence of talent now.
Objective To understand blood lead levels and occupational health status of lead-exposed workers in Tianjin，and analyze their associations with gender，age，and work seniority，in order to provide a scientific basis for occupational health surveillance. Methods A total of 1 022 lead-exposed workers who underwent occupational health examinations at Tianjin Occupational Diseases Precaution and Therapeutic Hospital from October 2022 to December 2023 were selected as the research subjects. According to GBZ 188-2014 "Technical Specifications for Occupational Health Surveillance"，blood lead，blood routine，urine routine，electrocardiogram and other examinations were conducted，and the data were analyzed. Results The abnormal rate of blood lead was higher in males than in females，with a statistically significant difference（χ2=20.231，P<0.01）. The abnormal rate of blood lead was highest in the 1-<10 years of work experience，with a statistically significant difference between groups（χ2=11.681，P<0.05）. There was no statistically significant difference in the abnormal rate of blood lead between different age groups（χ2=5.433，P>0.05）. In occupational health examinations of different genders，there were statistically significant differences in the abnormal rates of electrocardiogram，hemoglobin，and urine routine（χ2=8.042，68.951，17.273，all P<0.05）； There was no statistically significant difference in the abnormal rate of white blood cells（χ2=1.412，P>0.05）. Conclusion Protective measures should be strengthened for males and shorter-seniority workers，and targeted examinations should be conducted regularly to reduce the risk of lead poisoning and protect occupational health rights. Future research can further analyze the differences in exposure levels under different types of work and environmental lead concentrations.
Burnout is a state that affects people's work status and leads to life exhaustion，and exploring its pathogenesis can help us assess，diagnose and treat burnout，while biomarker indicators of burnout are of great significance for further elucidating the pathogenesis of burnout. This article reviews the research progress of neuroendocrine indexes，metabolic indexes，oxidative and antioxidant，inflammation and immune system in patients with burnout. It has been demonstrated in existing studies that some of the markers may have predictive ability for burnout，but there is some heterogeneity among studies due to differences in study populations and methods. In the future，large-sample prospective studies are needed for different stress stages and different populations to clarify the mechanisms of burnout to improve the prevention，diagnosis and treatment of burnout symptoms.

With the rapid development of information technology and the advent of the era of mutual media，the boundary between work and life is increasingly blurred.Work connectivity behavior after hours，that is，dealing with work affairs through electronic devices after work or during rest，has become a common phenomenon in modern workplaces. Focusing on nurses as a special occupational group，this connectivity behavior can not only enhance work flexibility and emergency response efficiency，strengthen nurses' sense of professional efficacy and responsibility，but also become a core stressor that erodes nurses' physical and mental health，induces burnout，exacerbates work-family conflicts，triggers emotional exhaustion and various types of health problems，which threatens the well-being of the individual，the harmony of the family，and the stability of the quality of nursing care，showing an obvious double-edged sword effect. Therefore，it is particularly important to conduct in-depth research on work connectivity behavior after hours. This paper reviews the concept，theory，measurement tools，influencing factors，outcome variables and intervention strategies of work connectivity behavior after hours，aiming to draw the attention of managers and to provide references for the study of work connectivity behavior after hours among nurses. Through scientific management and effective intervention，it is expected to alleviate nurses' occupational stress and promote work-life integration，which is of great significance in safeguarding nurses' physical and mental health and optimizing the allocation of nursing resources.
