Objective To explore the value of the concentration of adenosine triphosphate (ATP) in CD4(+)T lymphocytes in predicting repeated respiratory tract infections (RRTI) in silicosis patients. Methods In April 2020, 614 silicosis patients admitted from March 2016 to March 2018 were included in the study, and they were divided into the RRTI group (n=105) and the non RRTI group (n=509) according to whether the occurrence of RRTI, another 30 healthy cases taken from body check were served as control group, and the concentrations of ATP produced by CD4(+)T lymphocytes was measured by ImmuKnow assay, and were compared between the three groups. And drawed the receiver operating characteristic (ROC) curve, and the Logistic regression analysis was used to explore the risk factors of RRTI. Results The incidence of RRTI in silicosis patients was 17.10% (105/614) . The concentration of ATP produced by CD4(+)T lymphocytes in the RRTI group was significantly lower than that in the non RRTI group (t=-10.849, P less then 0.01) . The area under the ROC curve was 0.834, the cutoff value was 284 mg/L, the sensitivity was 0.88, and the specificity was 0.83. Logistic regression analysis showed that the concentration of ATP produced by CD4(+)T lymphocytes≤284 mg/L, impaired pulmonary ventilation function, serum albumin less then 40 g/L and diabetes were the risk factors of RRTI in silicosis patients (OR=2.126, 1.217, 1.164, 1.125, P less then 0.05) . Conclusion Low CD4(+)T lymphocyte ATP value was a risk factor of RRTI in silicosis patients, and can predict the risk of RRTI in patients with silicosis.Objective To understand the self-reporting rate of respiratory symptoms in bathing staff, and analyze the differences and influencing factors in the eastern, central and western regions. Methods From April to December 2017, adopt the method of multistage random sampling, the selection of the national 3865 effective questionnaires were bathing places practitioners, survey from personnel of course of demographic characteristics, cultural degree, family income, living habits, since the evaluation of environmental factors and respiratory symptoms such as self-reported rate content, using logistic regression model to analyze its influencing factors and regional differences. Results The prevalence of self-reported respiratory symptoms among employees in the eastern, central, and western regions was 17.86% (269/1 506) , 10.66% (126/1 182) , and 31.01% (365/1 177) respectively. The influencing factors in the eastern region are “age”, “family income”, “whether drinking”, “environment is suddenly cold and hot”, “dust in the air” (P less then 0.05) ; the influencing factors in the central region are “whether drinking”, “environment suddenly cold and hot”, ” poor ventilation”, “dust in the air” (P less then 0.05) . The influencing factors in the western region are “gender”, “whether drinking”, “environment suddenly cold and hot”, “poor ventilation” (P less then 0.05) . There are statistically significant differences in eastern, central and western regions (P less then 0.01) . click here Conclusion The prevalence of respiratory symptoms among bathing practitioners in China varies from region to region. Economic conditions, living habits, and environmental factors are the main influencing factors.Objective To evaluate the degree of anxiety and depression of medical staff during the epidemic period of the COVID-19, and to provide theoretical basis for the pertinence psychological intervention timely. Methods The investigation about the psychological status of 183 medical staffs on duty during the epidemic period was conducted using Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) from 18th to 20th February, 2020, who came from Tianjin and other provinces. The respondents were divided into first-line and non-first-line groups according to their jobs, and local and non-local groups according to their work places, respectively. The data was collected by “Star Questionnaires” using the mobile terminal, and the statistical analysis was carried out to compare whether there were differences in depression and anxiety among medical staff of different groups. Results The total SAS score (48.96±9.21) and SDS score (56.69±7.57) of all medical staff were higher than those of the national norm SAS (33.80±5.90) and SDS (41.88±10.57) from 1158 individuals (P0.05) . Conclusion The anxiety and depression exist obviously among the medical staff during the epidemic period of the COVID-19, and the psychological intervention should be taken out in time.Objective To explore the relationship between medical staff’s engagement, perceived organizational support and turnover intention. Methods In May 2019, 600 medical and nursing staff from a tertiary hospital in Tianjin were selected by random sampling method. The questionnaire survey was conducted by using Gallup Q12 questionnaire, perceived organizational support scale and turnover intention scale. The correlation between engagement, organizational support and turnover intention was analyzed by person correlation analysis and regression analysis, and multivariate stepwise linear analysis was used for multiple factor analysis Return. Results the total average scores of engagement, sense of organizational support and turnover intention were (2.18±0.56) , (3.48±0.72) and (2.71±0.67) respectively. There was a positive correlation between engagement and perceived organizational support (r=0.674, P less then 0.01) , and negatively correlated with turnover intention (R=-0.416, -0.487, P less then 0.05) . The factors of turnover intention were engagement and organizational support (F=54.673, 81.558, P less then 0.01) . Perceived organizational support partially mediated the relationship between engagement and turnover intention (P less then 0.01) . Conclusion The engagement and organizational support of medical staff are related to turnover intention.Objective To investigate the status of coal dust hazard classification and lung function damage in a large coal mine in Shanxi Province. Methods From January to June in 2019, 51 coal dust posts and 598 workers exposed to coal dust were selected from a large coal mine enterprise in Shanxi Province. The coal dust (exhaled dust) samples were collected and tested, and the hazard classification index of coal dust (exhaled dust) was calculated. The jobs exposed to coal dust (exhaled dust) were divided into relatively harmless, mild, moderate and severe hazard posts, and the corresponding workers were divided into relatively harmless group, mild, moderate and severe hazard groups. The forced expiratory volume (FEV1) , forced vital capacity (FVC) and forced expiratory volume/forced vital capacity (FEV1/FVC) in the first second were measured. Spearman rank correlation method was used to analyze the relationship between the hazard grade of coal dust and lung function. Results Among 51 coal dust (exhalation) posts, 13 coal dust (exhalation dust) exceeded the standard (25.
