Objective:To evaluate the efficacy of endoscopic stenting drainage for patients with malignant hilar biliary obstruction caused by unresectable hepatocellular carcinoma.Methods:Data of 106 patients with malignant hilar obstruction caused by unresectable hepatocellular carcinoma who received endoscopic stenting drainage in the Third Affiliated Hospital of Naval Medical University from January 2012 to January 2019 were retrospectively analyzed. According to the different stent types, they were divided into the metal stent group (30 cases) and the plastic stent group (76 cases). The observation indexes included clinical success rate, complication incidence, stent patency and overall survival time. The independent predictors for stent patency and overall survival of patients were analyzed by multivariate Cox regression model.Results:The overall clinical success rate was 67.9% (72/106) and the incidence of postoperative cholangitis was 29.2% (31/106). The clinical success rates were 93.3% (28/30) and 57.9% (44/76) ( χ2=12.40, P<0.001), and the incidences of postoperative cholangitis were 13.3% (4/30) and 35.5% (27/76) ( χ2=5.12, P=0.024) in the metal stent group and the plastic stent group, respectively. The median stent patency was 5.2 (95% CI:3.7-6.0) months, and the overall survival time was 3.0 (95% CI:2.5-3.7) months. Multivariate Cox regression analysis showed that hepatic drainage volume <30% was an independent predictor for stent patency ( HR=2.12, 95% CI:1.01-4.46, P=0.048). Bismuth type Ⅳ ( HR=2.06, 95% CI:1.12-3.77, P=0.020), Child-Pugh class C ( HR=4.09, 95% CI: 2.00-8.39, P<0.001) and plastic stent ( HR=1.87, 95% CI:1.21-2.90, P=0.005) were independent predictors for overall survival time. Conclusion:Hepatocellular carcinoma involving the hilar bile duct has a poor prognosis. Compared with plastic stents, metal stents show advantages in clinical success rate and incidence of postoperative cholangitis. Hepatic drainage volume <30% is an independent predictor for stent patency, and Bismuth type Ⅳ, Child-Pugh class C and plastic stent are independent predictors for overall survival time.

Objective:To explore the efficacy of the combination of radiofrequency ablation(RFA) and endoscopic metal stent in the treatment of patients with unresectable cholangiocarcinoma.Methods:From January 3, 2012 to June 30, 2019, at the Department of Endoscopic of the Third Affiliated Hospital of Naval Medical University, the clinical data of 44 patients with unresectable cholangiocarcinoma who were treated by the combination of RFA and endoscopic metal stent were retrospectively collected, which included age, gender, location of cholangiocarcinoma(hilar cholangiocarcinoma and distal cholangiocarcinoma), etc. Postoperative evaluation was conducted based on the follow-up, including clinical success rate, postoperative complication rate, time of stent patency and overall survival time (OS). The Kaplan-Meier method and log-rank test were used to analyze the difference of OS between patients with hilar cholangiocarcinoma and distal cholangiocarcinoma. Mann-Whitney U test was used for statistical analysis. Results:The age of the 44 patients with cholangiocarcinoma was (70.3±11.6) years old, with 20 males (45.5%). There were 22 patients (50.0%) with hilar cholangiocarcinoma and 22 patients (50.0%) with distal cholangiocarcinoma. The clinical success rate of 44 patients was 93.2%(41/44). A total of 5 patients(11.4%) had postoperative complications, which were all improved by appropriate treatment. The median time of follow-up of the 44 patient was 9.2 months(ranged from 3.1 to 57.6 months), the median time of stent patency was 7.0 months (ranged from 5.8 to 8.2 months). Thirty-two patients (72.7%) died during the follow-up, and the median OS was 10.9 months(ranged from 9.0 to 12.8 months). The median OS of patients with hilar cholangiocarcinoma was 7.8 months(ranged from 4.6 to 11.0 months) and that of patients with distal cholangiocarcinoma was 12.5 months(ranged from 5.7 to 19.4 months), and there was no statistically significant difference( P>0.05). Conclusion:RFA combined with endoscopic metal stent is safe and effective in the treatment of patients with unresectable cholangiocarcinoma.

ObjectiveTo determine the risk factors associated with hypoglycemia in community patients with type 2 diabetes mellitus（T2DM）. MethodsA case-control study was performed among 914 patients with T2DM and no medical history of hypoglycemia were selected in the Diabetes Unit of Tongji University School of Medicine Affiliated Anting Community Health Center in 2018. A total of 196 patients with T2DM who had ≥1 hypoglycemia event in the past 12 months were presented as the case group， and 718 patients who did not have any hypoglycemia event during the same period were included as the control group. Medical history， medication， life style， and related factors were collected. Multivariate logistic regression analysis was used to determine the risk factors associated with hypoglycemia. ResultsHistory of coronary heart disease ［adjusted odds ratio（aOR）=2.077， 95% CI： 1.293-3.337］， renal disease （aOR=4.775， 95% CI： 1.537-14.830）， and previous insulin use （aOR =1.765， 95%CI： 1.147-2.716） significantly increased the risk of hypoglycemia， while angiotensin converting enzyme inhibitors（ACEI）（aOR =0.127， 95%CI： 0.044-0.366） and β-receptor blockers （aOR =0.271， 95%CI： 0.119-0.616） decreased the risk of hypoglycemia among diabetic patients. ConclusionIncidence of hypoglycemia in community patients with diabetes is high. History of coronary heart disease and kidney disease， and previous insulin use may increase the risk of hypoglycemia， which warrants further attention by community general practitioners.
