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.

Objective To analyze the hospitalization expenses of cancer patients covered with byitem payment and quota payment packages,and probe into the impacts on such expenses for the two payment packages.Methods Inpatient records of 600 cancer patients were sampled by random from the medical insurance databases of Zhengzhou and Fuzhou to learn their hospitalization expenses and impact factors.Results Under the by-item payment package,the expenses of urban workers’ medical insurance were found higher than those of urban residents' medical insurance,with a per capita expense of RMB 32747.70 ± 32035.01 and 23035.83 ± 22875.65 respectively.Under the quota payment package however,there were no significant differences between expenses of the two kinds of inpatients,with a per capita expense of RMB 66043.41±47562.09 and 66576.54±73417.29 respectively.Conclusion There are gaps of reimbursement level between the two basic insurance schemes,which may not disappear in a short time.Under the by-item payment package,the gap exists in the difference of perreimbursement amount; under the quota payment package,the gap is negligible between the two populations under different insurance schemes.It is recommended to make reasonable use of these different payment schemes to minimize the relative gaps in medical service accessibility caused by the difference in reimbursement level.
