Biochemistry is an important basic medical course, and it is also a difficult course.In order to improve the comprehensive ability of seven-year program clinical medical students in Capital Medical University, teaching reform of Biochemistry was carried out.Teaching content was redesigned to strengthen the learning of basic knowledge of Biochemistry and to increase the depth of teaching content, while expanding the content by introducing new achievements and new technology to keep up with the forefront in the development of Biochemistry.Various methods such as the comparative method, case teaching and so on, were used flexibly in the teaching practice in order to improve teaching effects.The experiments carried out in the course were also redesigned and integrated, some distinctive experiments such as designing experiments, comprehensive experiments and innovative experiments were opened to improve students' hands-on ability and to cultivate students' scientific thinking.

Objective To observe the impact of IL-1β on the expression of lectin-like oxidized LDL receptor 1 (LOX-1) and ATP-binding cassette transporter A1 (ABCA1) in human mesangial cell line (HMCL), and its association with cholesterol homeostasis of HMCL. Methods Levels of LOX-1 and ABCA1 of HMCL induced by IL-1β were examined by using real-time PCR and Western blot. Results IL-1β up-regulated LOX-1 mRNA and protein expression. Treated with 5 μg/L IL-1β, the levels of LOX-1 mRNA and protein reached the peak after 6 h and 24 h of stimulation and were 6.87 folds and 1.88 folds of control rspectively. The expression of ABCA1 mRNA and protein of lipid-loaded HMCL was down-regulated by IL-1β Stimulated with 5 μg/L IL-1β the expression of ABCA1 mRNA and protein decreased to the lowest level, 19.0% and 50.62% of the baseline respectively. Conclusions The expression of LOX-1 can be up-regulated while the expression of ABCA1 can be decreased by the stimulation of IL-1β. IL-1β can enhance dyslipidemia and influence the balance of cholesterol homeostasis of HMCL.
