Objective To understand the current situation of occupational hazards in a magnetic material manufacturing enterprise in Jiangmen City,analyze the impact and degree of hazards on workers in the production process,identify the hazard analysis and critical control point（HACCP）,and provide reference for reducing the occurrence of occupational diseases and injuries among workers. Methods According to the occupational disease hazard factor testing report provided by the enterprise from 2022 to 2023,conduct occupational hygienic investigation,determine evaluation indicators,select 271 workers who underwent occupational health examinations in Jiangmen Occupational Disease Control Institute from 2022 to 2023 as the research subjects according to the excessive hazard factors,and analyze the occupational health examination data. Results The excessive rate of noise detection point in the enterprise was 43.86%,the other testing index were all under the national occupational exposure limits（OELs）. The abnormality rate of pure tone test was 60.15%,with a statistically significant difference in hearing abnormality rate between males and females（ χ²=15.020,P<0.01）. There was a statistically significant difference in hearing abnormality rate among males with different working years（ χ²=14.139,P<0.01）,while there was no statistically significant difference in hearing abnormality rate among females with different working years（ χ²=4.959,P>0.05）. There was no statistically significant difference in hearing abnormality rate among males exposed to different levels of noise intensity（ χ²=0.047,P>0.05）,while there was a statistically significant difference in hearing abnormality rate among females exposed to different levels of noise intensity（ χ²=5.227,P<0.05）. There was also a statistically significant difference in hearing abnormality rate among different positions（ χ²=16.098,P<0.01）. There was a statistically significant difference in hearing abnormality rate between the noise exposure group alone and the dust and noise exposure group （ χ²=7.540,P<0.01）. Conclusion The hygiene conditions in the workplace of the magnetic material manufacturing enterprise and the health examination status of noise exposures are not optimistic. It was necessary to find the HACCP and take measures to protect the health of workers in the industry.

Objective To investigate the multiple mediating roles of work engagement and job satisfaction between nurses' perceptions of decent work and turnover intention. Methods From July to August 2023,460 nurses from three grade-A tertiary hospitals in Hangzhou were selected as research subjects using convenience sampling. A general information questionnaire,decent labor perception scale,Utrecht work engagement scale,Minnesota satisfaction scale,and turnover intention scale were used for the survey to construct and test the chain mediation effect. Results The perceptions of decent work score of 460 nurses from three grade-A tertiary hospitals in Hangzhou was （53.42±10.63）points,the work engagement score was （51.17±16.27）points,the job satisfaction score was （71.95±13.68）points,and the turnover intention score was （14.07±3.83）points. Nurses' perception of decent work,work engagement,and job satisfaction were significantly negatively correlated with their turnover intention（r=-0.432,-0.435,-0.495,all P<0.01）. Perception of decent work was positively correlated with work engagement and job satisfaction（r=0.590,0.728,both P<0.01）,and work engagement was positively correlated with job satisfaction（r=0.728,P<0.01）. The mediation effect analysis showed that work engagement played a partially mediating role between the perception of decent work and turnover intention,with a mediation effect value of -0.024（95%CI：-0.054-0.003）,accounting for 15.4% of the total effect. The partial mediation effect of work satisfaction between perception of decent work and turnover intention was not significant,with an effect value of -0.043（95%CI：-0.069--0.019）,accounting for 27.6% of the total effect. Work engagement and job satisfaction played a chain mediating role between perception of decent work and turnover intention,with an effect value of -0.035（95%CI：-0.053- -0.015）,accounting for 22.4% of the total effect. Conclusion Nurses' perception of decent work can not only directly affect their turnover intention,but also affect their turnover intention through a chain mediation effect of work engagement and job satisfaction.

Methods Microsoft Excel 2017 software was used to input and sort the data,SPSS 20.0.0 software was used for statistical analysis. Chi-square test was used for comparison of incidence rates,chi-square trend test was used for trend change of incidence rate,and concentration M value and circular distribution were used for seasonal analysis. Results From 2013 to 2023,a total of 729 confirmed cases of pertussis were reported in Tianjin Binhai New Area,with an average incidence rate of 2.53/100 000,and the overall incidence rate showed an upward trend（ χ²_trend=27.54,P<0.01）. The concentration of monthly reported cases for combined 11 years was M=0.2529,showing poor seasonal distribution. Using the circular distribution to calculate the annual R value,the cumulative monthly distribution concentration trend values R for 2023 and 2013-2023 were 0.115 3 and 0.252 9,respectively,with statistically significant differences,indicating the seasonal distribution characteristics of pertussis incidence. The prevalence of pertussis in group aged ≥3 months and<1 year was the highest,accounting for 30.86%. The proportion of children aged 0-<1 year old accounted for about half or more of the total cases from 2015 to 2020,and gradually decreased from 2021 to the lowest 2023 of 19.87%. There was a statistically significant difference in the incidence rate of pertussis among the age groups from 2013 to 2023（ χ²=33781.99,P<0.01）,and the highest incidence rate was 234.50/100 000 in the 0-year-old group. The proportion of primary school children aged 6-12 in 2023 had reached the highest level of 52.98% in 11 nearly years.

Objective Long-term history of pulmonary tuberculosis is easy to induce lung cancer,and lung cancer patients are more likely to be infected with tuberculosis. The purpose of this study is to identify and verify the genetic characteristics associated with pulmonary tuberculosis,which can be used as a potential biomarker for the prognosis of patients with lung adenocarcinoma,and to construct a prognostic prediction model. Methods Differential expression and weighted gene co-expression network analysis（WGCNA） were performed on the GSE126614 datasets of pulmonary tuberculosis,candidate genes were obtained by intersection,and further survival analysis was performed in the cancer genome atlas（TCGA） lung adenocarcinoma database. Five core genes were finally selected by univariate and Lasso-Cox multivariate analysis,and a prediction model was further constructed and externally validated. Results Differential expression and WGCNA analysis were performed on the tuberculosis GSE126614 datasets,and 241 genes were obtained from the intersection for further survival analysis. Single factor and Lasso-Cox multivariate analysis were used to finally select 5 genes and construct a risk model. The risk model was as follows：risk score =（0.000 67×PPTC7 expression） +（-0.000 5×RHOQ expression）+（0.000 1×TRIM28 expression）+（-0.031×USP49 expression）+（-0.000 2×ZNF710 expression）. The internal validation results showed that the AUC values of 1-year,3-years and 5-years in the TCGA-LUAD training cohort were 0.755,0.747 and 0.723,respectively,and consistent predictive ability was also demonstrated in the TCGA-LUAD validation queue. In addition,external validation showed that the 1-year,3-year and 5-year AUC values of the ROC curve were 0.732,0.68 and 0.646,respectively,which also showed that the model had good predictive ability. Multivariate Cox analysis showed that risk score（P<0.001） was an independent prognostic factor. At the level of gene transcription,TRIM28,PPTC7,ZNF710 and USP49 were relatively highly expressed in lung adenocarcinoma tissues. At the translation level,TRIM28,PPTC7 and ZNF710 were relatively highly expressed in lung adenocarcinoma tissues. Conclusion The prognostic model composed of these five genes has certain value in predicting the prognosis of patients with lung adenocarcinoma,and can provide reference for clinical diagnosis and treatment.

Currently,population aging is showing a rapid upward trend. The decline of the elderly's physical function and the development of the emerging Internet have led to a serious shortage of social networks for the elderly,which has led to health problems for the elderly. The shrinking of social network of the elderly interacts with social and cultural factors in different environments. Therefore,this article elaborates on the concept of social networks and uses ecosystem theory as a framework to comprehensively summarize the relationship between social network and health status of the elderly from micro,meso,and macro perspectives. Finally,from the perspective of ecosystem theory,management measures and intervention plans for the shrinking of social networks among the elderly are proposed,in order to increase the attention of communities and nursing staff to the shrinking of social networks among the elderly and ensure effective health interventions for them.
