Objective To investigate the status of occupational hazards in large-scale coal mines in Wuchang region, Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang"). Methods Three large underground coal mines at Wuchang region from Xinjiang in 2022 were selected as research subjects using a purposive sampling method. Result of worksite survey of occupational health, occupational hazards detection, and occupational medical examinations of workers were conducted. ResultsThe main occupational hazards in the three coal mines were dust and noise. The level of free silica in 10 dust samples of workplaces was below 10.0%, indicating that the dust type was coal dust. The exceedance rate of the normalization of equivalent continuous A-weighted sound pressure level to a nominal 8 hours work day was 1.7% (2/119). The exceedance rates for exposure concentration of short term total dust and respiratory dust concentrations from fixed-point sampling were 2.1% (1/47) and 2.2% (1/45), respectively, while the exceedance rate for exposure concentration of time weighted average of respiratory dust from personal sampling was 8.9% (4/45). The occupational medical examination coverage rate among workers exposed to occupational hazards was 64.6% (1 149/1 780), and the abnormality rate was 20.7%. Conclusion The overall situation of occupational hazards in the coal mines in the Wuchang region remains concerning. The dust and noise levels exceed the national occupational health standard in some workplace. Attention should be paid to strengthen the management of dust and noise hazards in large underground coal mines in this region.

Objective To explore the application of Wechat platform step-by-step management in the health behavior of stroke patients.Methods A total of 69 stroke patients admitted to Department of Neurology,the First Affiliated Hospital of University of Science and Technology of China(Anhui Provincial Hospital)from January to March 2022,who met the inclusion and exclusion criteria,were selected as research subjects.The quasi-experimental study method was used to divide them into control group and intervention group,the patients of control group received routine health education,while the patients of intervention group implemented micro-platform step-by-step management.The health behaviors of two groups of patients were compared at four time points(1 month,3 months,6 months,and 12 months after stroke onset).Results The analysis results of the generalized estimation equation showed that there were statistically significant differences in the total scores of the health behavior scale,as well as in the dimensions of exercise,medication adherence,instruction following,and sense of responsibility at the four time points for both groups(P＜0.05).The nutritional dimension at 3 months,6 months,and 12 months after onset,and the smoking and drinking dimension at 12 months after onset,showed statistically significant differences between two groups(P＜0.05).Conclusion The Wechat platform step-by-step management helps to improve the health behavior of stroke patients,and enhance the health management effects of stroke patients.
