According to the changeover of modern medical teaching mode and the undergraduates' need of knowledge structure,we started the course Sociology of Sexuality in our university.In more than 3 years teaching experience and exploration,we arranged the content for each part of each chapter based on the teaching outline,teaching scheme and the students' knowledge and ability structure.As to teaching method,we adopted multimedia computer instruction,heuristic instruction,interactive instruction,participating teaching and audio-visual digital teaching method and so on.We are to introduce such a teaching means of exchange communication,and such an examination method combined with the traditional test as well as testing the capability of handling the actual problem,which can help to implementing the teaching work for Sociology of Sexuality.

Objective To explore the risk factors of hepatic failure after major hepatectomy. Methods Clinical data of 293 patients receiving major hepatectomy in Sun Yat-sen Memorial Hospital of Sun Yat-sen University between January 2008 and February 2017 were retrospectively analyzed. The informed consents of all patients were obtained and the local ethical committee approval was received. According to whether there was postoperative hepatic failure, the patients were divided into the hepatic failure group and non-hepatic failure group. There were 23 cases in the hepatic failure group, including 22 males and 1 female with the mean age of (53±12) years. There were 270 cases in non-hepatic failure group, including 224 males and 46 females with the age of (49±12) years. Single factor analysis and Logistic regression analysis were used to analyze the risk factors of postoperative hepatic failure. Results The incidence of hepatic failure after major hepatectomy was 7.8% (23/293). Multi-factor Logistic regression analysis showed that preoperative Plt, Child-Pugh classification of liver function, tumor diameter and vascular tumor thrombus were the independent influence factors of postoperative hepatic failure (OR=0.983, 0.020, 0.726, 0.225;P<0.05). Conclusion Preoperative Plt, Child-Pugh classification of liver function, tumor diameter and vascular tumor thrombus are the independent influence factors of hepatic failure after major hepatectomy.

Objective:To explore the best treatment for local ablation of colon cancer liver metastases (CRLM) by meta-analysis.Methods:The electronic databases of PubMed, Web of Science, Embase, CNKI and the Cochrane Library were searched from the establishment to August 22, 2022, and studies that report outcomes with comparison between microwave ablation (WMA) and radiofrequency ablation (RFA) in CRLM treatment were selected by inclusion and exclusion criteria. Furthermore, the perioperative and survival data were statistically summarized and analyzed by Review Manager 5.3 software.Results:A total of 5 retrospective studies were included with a total sample size of 648 cases, including 316 cases (48.8%) in the WMA group and 332 cases (51.2%) in the RFA group. The results of meta-analysis showed that locoregional recurrence rate in WMA group was significantly lower than that in RFA group. The 1-year and 2-year disease-free survival (DFS) of the WMA group was significantly better than that of the RFA group with HR of 1.77 ( P=0.04, 95% CI: 1.04-3.02) and 1.60 ( P=0.02, 95% CI: 1.09-2.35), respectively. Conclusion:The local control rate and 1-year and 2-year DFS of WMA were superior to RFA.
