Medical educational internationalization has already made teaching medical courses in English more and more important.Nephrology department in Tongji hospital affiliated to Tongji medical college,Huazhong university of science and technology has assumed the responsibility of teaching in English for medical students of five-year program,six-year program,seven-year program,eight-year program,and abroad student for several years.They practiced teaching in English in theory teaching,PBL teaching and clinical teaching according to the characteristics and requisitions of students in different educational systems.They accumulated some experiences,which was conducive to improving the quality of teaching in English.

The safety of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) used in hemodialysis (HD) patients was evaluated. Medline, Embase, the Cochrane Library, some databases of clinical trial registries, grey literatures, other reference lists of eligible articles and review articles for the randomized clinical trials (RCTs) on comparison of ACEIs/ARBs or placebo in HD patients were retrieved. RCTs reporting the risk of hyperkalemia by using ACEIs/ARBs in HD patients were selected. Eight articles met the eligibility criteria and were subjected to meta-analysis by using the Cochrane Collaboration's RevMan 4.2 software package. The results showed that there was no significant difference in hyperkalemia in HD patients between ACEIs or ARBs group and control group (ACEIs vs. control: RD=0.03, 95% CI=-0.13-0.18, Z=0.34, P=0.73; ARBs vs. control: RD=-0.02, 95% CI=-0.07-0.03, Z=0.75, P=0.45). However, there was no significant difference in the serum potassium between ACEIs or ARBs group and control group in HD patients (ACEIs vs. control: WMD=0.10, 95% CI=0.06-0.15, Z=4.64, P<0.00001; ARBs vs. control: WMD=-0.24, 95% CI=-0.37-0.11, Z=3.58, P=0.0003). The use of ACEIs or ARBs could not cause an increased risk of hyperkalemia in HD patients, however the serum potassium could be increased with use of ACEIs in HD patients. Therefore the serum potassium concentration should still be closely monitored when ACEIs are taken during the maintenance HD.

Clinical practice teaching in out-patient department is an important part of general internal clinical teaching for medical students. From 2010, eight-year program medical students in Huazhong University of Science and Technology began their clinical rotation practice in the out-patient department of general internal medicine. The one-on-one tutoring style was used in clinical teaching. We combined teacher demonstration teaching method with teacher supervision teaching method in clinical practice, and carried out periodical case discussion. At the end of each rotation stage, regular teaching evaluation and examination was taken. It has been proved that our teaching mode can not only help the students improve their professional and practical levels of clinical skills, and also help them gain the clinical working abilities and the professional spirits, which is worthy of further promotion.

Teaching urinary system diseases by problem-based learning method for eight-year program medical students was applied in nephrology department in affiliated Tongji hospital of Huazhong university of science and technology since 2008.They had accumulated experiences in compiling teaching plan,fostering teachers,practicing teaching and evaluating teaching.These steps may future intensify education reform on long schooling system and improve teaching quality of eight-year program.
