Objective To analyze the prevalence of cardiovascular disease (CVD) risk factors among nurses with high job stress in a Kunming tertiary hospital. Method The health data from 46 nurses who had gotten a medical examination between August 1 and November 30,2013 in the first people's hospital retrospectively analyzed .Results 76%of 46 nurses enrolled in this study had inordinately CVD risk factors,the top prevalence of CVD risk factors was dyslipidemia (58.9%),followed by hyperviscosity (45.5%),electrocardiographic abnormality (30.8%),overweight (19.2%),and hypertension (9.2%) . Moreover,there was significant differences of CVD risk factors among different departments ( <0.05),which the overall prevalence rate being highest among nurses working in the operating room. Conclusion The nurses with high job stress from tertiary hospital have high risks of CVD,therefore intervention measures should be taken to reduce the risk of CVD.

Background and Aim:Sulfotransferase(SULT)-mediated sulfation and steroid sulfatase(STS)-mediated desulfation represent two critical mechanisms that regulate the chemical and functional homeostasis of endogenous and exogenous molecules.STS catalyzes the hydrolysis of steroid sulfates to form hydrox-ysteroids.Oxygenated cholesterol derivative oxysterols are known to be endogenous ligands of the liver X receptor(LXR),a nuclear receptor with anti-cholestasis activity,whereas the sulfated oxysterols antagonize LXR signaling.The conversion of sulfated oxysterols to their non-sulfated counterparts is catalyzed by STS.The aim of this study is to determine whether STS can alleviate cholestasis by increasing the activity of LXR. Methods:Liver-specific STS transgenic mice were created and subject to the lithocholic acid(LCA)-induced model of cholestasis. Results:Transgenic overexpression of STS in the liver promoted bile acid elimination and alleviated LCA-induced cholestasis.The protective effect of the STS transgene was associated with the activation of LXR and induction of LXR target genes,likely because of the increased conversion of the antagonistic oxy-sterol sulfates to the agonistic oxysterols. Conclusions:STS has a novel function in controlling the homeostasis of bile acids by regulating endog-enous LXR ligands.

Objective:To evaluate the day-surgery unit-based training of laparoscopic cholecystectomy (LC).Methods:Perioperative data of 438 patients (187 males and 251 females) with a median age of 54 (aged 17 to 91) years undergoing LC during January 2019 to April 2021 in the day-surgery unit of Chinese PLA General Hospital were retrospectively collected and subdivided according to the training methods of surgeons [Group A( n=260): conventional training vs. Group B ( n=178): protocoled stepwise training]. The protocoled stepwise training consists of the rotation in open biliary surgery unit, the stimulator-based laparoscopic training, and the stepwise procedural tutoring. The conventional training features the traditional surgical practice following senior surgeons. The technical data involving operation time, blood loss, the percentages of intraoperative decision-making by senior surgeons and the handing-over of procedure to senior surgeons, etc. were statistically analyzed. Results:The operation time was shortened in Group B [(55±30) min vs. (61±33) min], with significantly decreased percentages of intraoperative decision-making by senior surgeons [7.9% (14/178)vs. 16.9%(44/260), P<0.05] and the handing-over of procedure to senior surgeons [3.4%(6/178) vs. 11.2%(29/260), P<0.05]. Conclusion:Based on the protocoled stepwise training and the consecutive, high-volumed and standardized procedures, the laparoscopic technical proficiency and competency of the trainee surgeons have been improved.
