The present study was conducted to investigate workplace violence and to examine how it is associated with quality of life (QOL) among medical professionals in China. A total of 2,464 medical professionals were selected from Fujian Province and Henan Province by using stratified cluster-sampling method. A Chinese version of the workplace violence scale was used to measure the incidence of workplace violence. The Short Form-36 Health Survey was employed to assess their QOL. Approximately 50% of the participants reported at least one type of workplace violence occurring in the previous 12 months. The multivariate analysis demonstrated workplace violence as a significant predictor for QOL among medical professionals, after controlling for other potential predictors. It suggests that the implementation of violence prevention policies and strategies to reduce workplace violence may improve QOL of medical professionals in China.

Objectives: The present study aimed to evaluate the hypertension status of community residents, analyze environmental and epigenetic factors, and propose prevention measures for hypertension. Methods: In our study, different methylation levels were distinguished utilizing melting temperature (T_m) values in both the case and the control group. Multiple logistic regression analysis was used to estimate the risk of having essential hypertension (EH) between hypertensive and nonhypertensive participants. A receiver-operating characteristic curve was used to analyze T_m cutoff levels of methylation. Results: The average DNA T_m was 71.784 with a standard deviation of 0.210. The T_m value of community residents (Fujian, China) was inversely correlated with systolic and diastolic blood pressure. Student t test analysis showed a clear separation in T_m expression levels between the hypertensive and the control group (p < 0.05). The T_m value was lower in the hypertension group than in the normotensive group. Multivariate regression analysis showed that high levels of DNA methylation were a protective factor in hypertension with adjustment of demographic and environmental factors, whereas when the T_m value increased by 0.1 units, the risk of hypertension was reduced by 0.652 times. Patients that smoked and consumed an irregular diet demonstrated a lower degree of methylation in the presence of hypertension. Conclusions: DNA methylation affects the risk for the development of hypertension; therefore, epigenetic markers could be used to measure hypertension levels to help elucidate the pathogenesis of EH.
