Objective: To analyze the trends of weight, blood pressure and serum uric acid levels in college graduates during 2016-2020, so as to provide the evidence for chronic diseases prevention and control in university students. Methods: A cross sectional study was conducted to collect the data of physical examination of new graduates of Peking University during 2016-2020. It analyzed the differences in the BMI, blood pressure, serum uric acid, prevalence of overweight/obesity, hypertension, and hyperuricemia. Results: For males, the prevalences of overweight/obesity, hypertension of 2016-2020 and hyperuricemia of 2018-2020 varied significantly ( χ 2=52.94, 37.63, 55.53, P <0.01), but not significant difference of overweight/obesity, hypertension among the four groups of 2016-2019 ( χ 2=6.45, 1.05, P >0.05). The highest prevalences of overweight (29.25%), obesity ( 11.37 %), hypertension (12.60%) and hyperuricemia (43.84%) were observed in the group of 2020. For females, the prevalence of hypertension of 2016-2020 and hyperuricemia of 2018-2020 were significantly different ( χ 2=14.14, 14.59, P <0.01)，but not significant difference of hypertension of 2016-2019( χ 2=0.34, P >0.05). The highest prevalences of hypertension (2.35%) and hyperuricemia (13.86%) were both found in the group of 2020. Conclusion High prevalence of hypertension and hyperuricemia in college graduates of 2020 suggest unhealthy lifestyle probably has adverse impact on health consequences in young adult students.

Objective:To explore the effect of multidiscipline team for pain (PMDT) led by anesthesia nursing team in perioperative period of liver transplantation patients.Methods:From January 2018 to December 2020, 100 patients with liver transplantation who were admitted to Beijing Friendship Hospital affiliated to Capital Medical University were selected as the study subject by convenience sampling. According to the method of random number table, the patients were divided into the control group and the observation group, 50 cases in each. The patients in the control group received routine pain management during the perioperative period, and the patients in the observation group received PMDT led by the anesthesia nursing team on the basis of the patients in the control group. The anesthesia related indexes and the use of analgesia pump were compared between the two groups.Results:The operation anesthesia time, anesthesia resuscitation time, and the use time of the patient-controlled analgesia pump in the observation group were shorter than those in the control group, the dosage of sufentanil and dexmedetomidine in the patient-controlled analgesia pump was lower than that in the control group, the above differences were statistically significant ( P<0.05) . Conclusions:PMDT led by anesthesia nursing team can effectively shorten the anesthesia time of liver transplantation, reduce the dosage of postoperative analgesics, and improve the analgesic effect.

Biocompatibility has always been the focal point in the study of biomaterials applied to medical apparatus. But at present, the standard system hasn't formed completely to evaluate the biomaterials. In recent years scientists tend to use general standard of evaluation. In this article, based on the recalcification time, the adhesion of platelets as well as the total quantity of plasma protein and some other evidences, combining with the Analytic hierarchy process (AHP), the method of general evaluation on the biocompatibility of anticoagulant biomaterials was discussed.

Objective To explore the value of quantitative chest CT in early diagnosis of chronic obstructive pulmonary disease(COPD).Methods The clinical data of 138 cases of COPD high-risk patients in Shanghai community and COPD high-risk respondents in outpatient clinic of Zhongshan Hospital,Fudan University from September 20,2013 to May 20,2014 were retrospectively analyzed.All high-risk participants underwent pulmonary function and chest CT examination at baseline and 1 year later.Chest CT images were imported into quantitative CT analysis software to collect quantitative CT data.These participants were divided into COPD group(n=40)and non-COPD group(n=98)based on their lung functions after 1 year.The differences in baseline lung function and quantitative CT measurements between the two groups were compared.Binary logistic regression was used to analyze the predictors of COPD in high-risk individuals after 1 year of follow-up,and the efficacy of the logistic regression model was evaluated by ROC curve.Results There were no significant differences in gender,body mass index(BMI),the percentage value of forced expiratory volume in 1 second predicted(FEV1%pred),airway wall area ratio(WA%),total airway count(TAC),and airway wall thickness(WT)between the two groups at baseline.Compared to the non-COPD group,the square root of the tracheal wall area at 10 mm from the inner circumference of the airway(Pi10),(3.43[3.30,3.54]vs 3.23[3.15,3.36],P＜0.001),and the percentage area of low attenuation regions below ﹣950 HU(LAA%﹣950),(2.06[0.32,6.29]vs 0.57[0.25,1.89],P=0.015)were significantly higher in the COPD group.The mean lung density(MLD)in the COPD group was lower than that in the non-COPD group([﹣799.89±35.62]vs[﹣783.60±43.52],P=0.038).Binary logistic regression analysis indicated that age and Pi10 were risk factors for COPD(P＜0.05),with an area under the ROC curve of 0.791(95%CI 0.714-0.868).Conclusions In the COPD high-risk population with normal lung function,patients with elevated Pi10 and LAA%﹣950 have a higher incidence of COPD one year later,suggesting that quantitative chest CT measurements such as Pi10 and LAA%﹣950 can assist clinicians in identifying early-stage COPD.
