Objective To investigate the stress reaction of the medical staff who suffered workplace violence,and provide reference for nursing interventions.Methods 13 medical staff who suffered work-place violence were interviewed through semi-constitutional formula,the data were analyzed by phenomenological method of qualitative research.Results The psychological stress of medical staff mainly included 3 themes:complex emotions,eager to help; psychological adjustment required internal and external integration; different stress reaction affected the psychological state.Conclusions The medical staff suffer seriously from the workplace violence both on the physical and mental health,individuals should learn how to deal with it correctly,and the relevant departments should pay full attention to the humane care to victims of violence,guide them to view the stress correctly,and to take effective measures to prevent and control workplace violence.

Objective:To evaluate the value of shear wave elastography (SWE) in skin assessment of Systemic sclerosis (SSc).Methods:A total of 58 SSc patients admitted to Peking University Third Hospital from May 2021 to October 2022 and 41 healthy volunteers were included in the study. Skin shear wave elastography (SWE) was performed at 17 sites defined in modified Rodnan skin score (mRSS) measurement, and shear wave velocity values were recorded to evaluate skin hardness. SPSS 22.0 software was used to analyze the skin hardness of SSc patients and healthy controls, and the correlation between skin hardness of SSc patients and clinical data was analyzed. A logistic regression model was constructed to evaluate the diagnostic efficacy of skin hardness at different sites of SSc patients, and to further select the most practical measurement site.Results:The SWE value of SSc patients was significantly higher than that of healthy control group ( P<0.05). There was a positive correlation between SWE and mRSS in the measurement of bilateral fingers, bilateral dorsal hands, bilateral forearms, fore-chest, abdomen, bilateral thighs, and bilateral dorsal feet. Skin stiffness measured by SWE was significantly correlated with SSc disease activity score (EScSG-DAI), ( r=0.71, P<0.001), disease injury score (SCTC-DI), (P=0.55, P=0.005) and functional score (HAQ-DI), ( r=0.46, P=0.003). Reducing the number of measurement sites to 12 (bilateral fingers, bilateral hands, bilateral forearms, bilateral upper arms, forehead, fore-chest, bilateral dorsum of feet) performs as well as all 17 measurement sites simultaneously in assessing disease activity. Conclusion:SWE is a good evaluation tool to reflect the skin lesions of SSc, which is of great value for the diagnosis and evaluation of the disease. We can further standardize the measurement sites and select the most appropriate evaluation strategy, so as to achieve better clinical application.
