Objective To investigate the current status of workplace violence among Nursing Staff. Methods The Modified Version of Hospital Workplace Violence Questionnaire was used to investigate 792 nursing staff about their experiences of workplace violence over the past one year in a third-grade Class-A comprehensive hospital in Xi′an city. Results The prevalence of workplace violence among 792 participants was 58.08%(460/792), Outpatient department, Emergency department, Obstetrics and Gynecology department, Pediatrics department were the high-risk areas of workplace violence. Day-shift was the main period of workplace violence occurred. The families of patients, middle-aged, male were the main perpetrators. 72.60%(575/792) of the respondents thought the workplace violence were unavoidable. Correct media orientation (89.33%, 707/792) was considered as the primary measure for preventing workplace violence. Patience explanation (74.13%, 341/460), forbearance (53.04%, 244/460) were the main methods for coping with hospital workplace violence. Grievances (75.38%, 347/460), anger (65.65%, 302/460), part of them even wanted to resign (21.84%, 100/460) after experiencing workplace violence were their feelings. Security patrols (81.63%, 647/792), wards installed cameras (77.43%, 613/792) and bright lights (53.42%, 423/792) in the night work areas were the main measures to prevent workplace violence that the hospital had taken to prevent workplace violence. Conclusions Workplace violence among nursing staff is common. It is suggested that hospitals and the relevant government departments should conduct further intervention research, to formulate feasible administrative riot guiding for reducing the incidence of workplace violence.

OBJECTIVE: To observe waveform difference among cervical vestibular evoked myogenic potentials (cVEMP) elicited with different types of air conducted sound in normal young Chinese subjects. METHOD: Twenty adult volunteers (40 ears) were recruited as research subjects including 10 males and 10 females aged between 19 and 30.500 Hz Tone Burst, 1000 Hz Tone Burst and Click were employed as stimulus for conventional air conducted sound-cVEMP (ACS-cVEMP) examinations in bilateral ears of each subject. The response rate, threshold, P1 latency, N1 latency, P1-N1 latency interval, amplitude and inter-aural asymmetry were recorded and compared among groups. RESULT: The response rate was 97.5% in 500Hz Tone Burst (39/40), 87.5% in 1 000Hz Tone Burst (35/40)and 67.5% in Click (27/40), There were no statistically significant difference between 500Hz Tone Burst and 1000Hz Tone Burst (P > 0.05) but there were statistically significant difference between click and the other groups (P < 0.05). We collected the waveform parameters (the threshold, P1 latency, N1 latency, P1-N1 latency interval, amplitude) which had statistically significant difference between 500 Hz Tone Burst and the other groups (P < 0.05). The inter-aural asymmetrys had no statistically significant differents among groups. CONCLUSION The response rate and parameter could be affected by different types of air conducted sound in normal young Chinese subjects. 500 Hz Tone Burst was the best stimulus of type what we have known.

Polyhydroxyalkanoate depolymerase (PHAD) can be used for the degradation and recovery of polyhydroxyalkanoate (PHA). In order to develop a PHAD with good stability under high temperature, PHAD from Thermomonospora umbrina (TumPHAD) was heterelogously expressed in Escherichia coli BL21(DE3). At the same time, a mutant A190C/V240C with enhanced stability was obtained via rational design of disulfide bonds. Characterization of enzymatic properties showed that the mutant A190C/V240C had an optimum temperature of 60 ℃, which was 20 ℃ higher than that of the wild type. The half-life at 50 ℃ was 7 hours, at 50 ℃ which was 21 times longer than that of the wild type. The mutant A190C/V240C was used for the degradation of polyhydroxybutyrate (PHB), one of the typical PHA. At 50 ℃, the degradation rate of PHB being treated for 2 hours and 12 hours was 2.1 times and 3.8 times higher than that of the wild type, respectively. The TumPHAD mutant A190C/V240C obtained in this study shows tolerance to high temperature resistance, good thermal stability and strong PHB degradation ability, which may facilitate the degradation and recovery of PHB.
