It is unable to cultivate students' ability of application and innovation by the traditional teaching form in pharmaceutics for the pharmaceutics is fragmented and intersective with other disciplines. This paper analyzes the characteristics and shortcomings of traditional teaching methods of pharmaceutics. The flipped classroom is applied to pharmaceutics teaching with SPOC, world coffee and hacker. The results shows that the flipped classroom can effectively improve the motivation and learning efficiency of students, especially improve their self-study and innovation ability. It can realize the diversity of teaching evaluation.

0.05),and their costs were 1 026.9,1 481.8,and 1 472.3 yuan respectively.CONCLUSION:The result showed that Group A was more reasonable and economical among the three schemes.

OBJECTIVE To discuss the cause of CABG infection and its controlling methodology. METHODS In order to conduct comparative analysis of 40 cases of CABG incision infection and 40 cases of CABG without infection,the "rank sum test" statistical models were applied. RESULTS According to the analysis of statistics,the hospitalized days and costs in sample group with infection were higher than that of control group,and the difference had statistical significance.Compared with the control group,the hospitalized days of sample group with infection averagely increased 43.03 days(2.85 times),and the total hospitalized costs of it averagely increased RMB 84 314.38 yuan(2.02 times). CONCLUSIONS Apart from patients themselves,there are also many possibilities which will cause the infection,which request the on-going works on surgery skills improvement,standardizing the process of aseptic technique,disinfection and isolation,utilizing antimicrobial agents rationally,reducing patients′ hospitalized days before surgery,as well as improving the pre-operative management etc.

OBJECTIVEA study was conducted to investigate the effects of Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) on the expression of regulated upon activation normal T-cell expressed and secreted (RANTES) and fractalkine in human umbilical vein endothelial cells (HUVECs).

METHODSHUVECs were incubated with different concentrations of Pg-LPS (200, 500, and 1000 ng x mL(-1)) for 1, 6, 12, and 24 h, respectively. Then real time quantitative polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent method (ELISA) were adopted to detect the protein levels and mRNA levels of RANTES and fractalkine.

RESULTSThe RANTES protein levels and mRNA levels, as well as fractalkine mRNA levels, were significantly higher in all experimental groups of 1, 6, and 12 h than in the control group (P<0.05), except the expression of RANTES mRNA in 200 ng x mL(-1) group of 12 h and RANTES protein in 200 ng x mL(-1) group of 1 h. The expression levels of RANTES mRNA and fractalkine mRNA were highest in 1000 ng x mL(-1) group of 6 h and were 4.88- and 6.20-fold higher, respectively, than those in the control group. The expression levels of RANTES protein, mRNA, and fractalkine mRNA decreased 6 h after stimulation, and were significantly higher than those in the control group (P<0.05) in the RANTES and fractalkine in HUVEC, and such expression is important in the development of atherosclerosis 500 ng x mL(-1) group of 24 h. There was a significant difference between the expression of fractalkine mRNA in 1000 ng x mL(-1) group of 6 and 12 h than in the control group (P<0.05).

CONCLUSIONPg-LPS infection might up-regulate the expression of RANTES and fractalkine in HUVEC, and such expression is important in the development of atherosclerosis.

Objective:To investigate the expression of MMP-1 and MMP-8 in periodontal tissues in rats with periodontitis at different stages of inflammation with varied severity. Methods:Periodontitis was induced by silk ligature. P.gingivalis(Pg) or Pg with F.nu were used to induce the varied severity of periodontitis in 40 rats. 14 and 28 days after periodontitis induction the animals were sacrificed, periodontal tissues were immunohistochemically stained by antibody of MMP-1 and MMP-8 respectively. Results:MMP-1 and MMP-8 were both strongly positive in gingival epithelia cells and fibroblasts in periodontal ligament in rats with periodontitis.Higher expression of MMP-1 and MMP-8 was observed at 14 d than at 28 d(P0.05). Conclusion:The expression of MMP-1 and MMP-8 varies in different stage of periodontitis. MMP-1 and MMP-8 may play an important role in development of periodontitis.

Objective To evaluate the clinical efficacy of lamivudine in preventing liver injury induced by anti-tuberculosis drugs in hepatitis B virus(HBV)carriers.Methods One hundred and ten HBV carriers treated with anti-tuberculosis drugs were randomly divided into lamivudine group and control group.Patients in both groups were treated with conventional anti-tuberculosis drugs (isoniazid,rifampicin,pyrazinamide,streptomycin or ethambutol)for 6-8 months.However, patients in lamivudine group were treated with lamivudine 100 mg orally dairy concomitantly.Before and after treatment,the clinical manifestation,liver function and serum HBV DNA level of patients were evaluated.Statistical analysis was performed using t test and x~2 test.Results During 6-8 months of treatment,the incidence rate of liver injury was 9.1% in lamivudine group,while it was 38.2% in control group(P0.05).Conclusion Lamivudine is effective and safe in reducing liver injury induced by anti-tuberculosis drugs in HBV carriers.

The evaluation of quality of life after stroke primarily includes body,psychology, society,and the ability of activities of daily living,and they can be mainly obtained from self rating quality of life by the patients,The commonly used evaluation methods include six generic measurement scales and four updated Stroke Specific Quality of Life Scales.The latter includes the Stroke Adapted Sickness Impact Profile,the Stroke Impact Scale,Stroke Specific Quality of Life Scales,and Stroke and Aphasia Quality of Life Scale.This article reviews the generic meas- urement scales,Stroke Specific Quality of Life Scales and the various factors that influencing quality of life after stroke.

The recombination clones contained CFP, LTB-ST foreign gene were screening by PCR using individual bacterial colonies as template, the aimed band was amplified from positive clones, the result was as well as plasmid PCR. The selecting of agrobacterium transformed with recombination plasmid could also use this method of PCR screening of individual bacterial colonies. The result of individual bacterial colonies PCR was as well as that of PCR using bacterial solution as template. It showed that the method individual bacterial colonies PCR was an efficient, easy one that characterized recombination clones.
