In 2008, 2011, 2013, and 2015, important turning points for research changes exist. Conclusion In the future, researchers in China can try to broaden the scope of medical subjects and influencing factors, etc., and be closely linked to the results of existing studies.Objective To investigate the current situation of occupational hazards in automobile manufacturing enterprises in Shandong Province. Methods From February to May 2019, the convenience sampling method was adopted to conduct on-site occupational health surveys with 20 automobile manufacturing enterprises in Shandong Province as the survey subjects, to detect the occupational hazard factors in the workplaces and individual exposure levels, and to analyze the occupational health check results of operators. Results There were 13 small-sized, 4 medium-sized and 3 large-sized enterprises among the 20 automobile manufacturing enterprises. The detection results of benzene and toluene in the workplaces met the occupational exposure limits, and the detection results of welding fumes, manganese and its compounds, and xylene exceed the occupational exposure limits. https://www.selleckchem.com/JAK.html The maximum short-term exposure concentration (C(STE)) of welding fume in the air of workplaces was 24.23 mg/m(3), and the over-standard rate was 11.0% (16/146here was a statistically significant difference in the detection rates of suspected occupational diseases among the operators of different scale automobile manufacturers (P less then 0.05) . Conclusion The exposure levels of electric welding fumes, manganese and its compounds in welding jobs and xylene exposure levels in spray painting jobsin Shandong Province's automobile manufacturing enterprises are more serious. The supervision and management of occupational hygiene should be strengthened, the working environment should be improved, and the health of welding and painting workers should be protected.Objective To explore the relationship between the health literacy of employees and smoking, drinking, diet and exercise, and provide scientific basis for health education and targeted intervention. Methods From February to July 2019, a cluster random sampling method was adopted to select enterprise employees in Shihezi City to conduct a questionnaire survey. Self-made questionnaires and "National Resident Health Literacy Monitoring Questionnaire" were used to assess the social demographics, health literacy, and Health-related behaviors were investigated, and 1053 valid questionnaires were collected. Logistic regression model was used to analyze the relationship between health literacy and the three dimensions with smoking, drinking, diet and exercise. Results Total score of health literacy of enterprise employees is (42.06±11.03) points and the employee health literacy rate of Shihezi City in 2019 is 19.47%. Univariate analysis showed that non-smokers had higher health literacy and three-dimensional health literacy availability than smokers (P0.05) ; there is a statistical correlation between health literacy, healthy lifestyles, behaviors, and health skills and regular exercise among employees (OR=1.829、2.503、1.395, P less then 0.05) ; employees with health literacy and three dimensions of health literacy are more likely to have a balanced diet (P less then 0.01) . Conclusion There is a correlation between the health literacy of enterprise employees and diet and exercise. The improvement of health literacy level is an important way to interfere with unhealthy behaviors.Objective To explore the effect of failure mode and effect analysis (FMEA) in the management of nosocomial infection, and provide reference for the effective prevention and control of nosocomial infection. Methods Using FMEA to identify, analyze, evaluate and screen out the high-risk events of nosocomial infection in January 2020, from which two hospital level priority improvement projects of hand hygiene compliance and blood-borne occupational exposure were determined. After risk control and intervention measures, the effects before and after improvement were compared. Results Except for the lack of incentive mechanism and insufficient communication between medical and nursing teams, the differences in hand hygiene compliance and blood-borne occupational exposure risk priority coefficients before and after the implementation of FMEA were statistically significant (P less then 0.05) . After the implementation of FMEA, the hand hygiene compliance was 74.92% (79375/105953) , which was significantly higher than 68.40% (58361/85328) before the implementation of FMEA, and the difference was statistically significant (χ(2)=996.55, P less then 0.01) . The incidence of blood-borne occupational exposure after the implementation of FMEA was 3.85% (80/2080) , which was lower than the 6.16% (123/1998) before the implementation of FMEA, and the difference was statistically significant (χ(2)=11.49, P less then 0.01) . Conclusion FMEA has a good effect in nosocomial infection management. It can identify and evaluate the risk of nosocomial infection prospectively, so as to control the risk effectively.Objective A Meta-analysis was used to evaluate the high frequency hearing loss detection rate, its area and time distributions in occupational noise exposed workers in China to provide evidence for the prevention and control of occupational noise-induced deafness. Methods From February to April 2020, the number of hearing tests and the number of binaural high frequency average hearing threshold ≥40 dB of workers exposed to noise in key occupational disease monitoring and occupational health risk assessment project in China was collected from China National Knowledge Infrastructure (CNKI) , VIP database and PubMed database. The retrieval time was set from the establishment of the database to February 28, 2020. The R 3.6.2 software was used to calculate the pooled high frequency hearing loss detection rate. Results A total of 28 studies, included 34 data and 1259571 occupational noise exposed workers, were enrolled. The articles covered 16 provinces in 2015-2018. The pooled high frequency hearing loss detection rate in occupational noise exposed workers was 9.
