Beginning from the tradition branch course obstacle analyzing on college student' practice ability,to define the effect and study domain and key problem about curriculum integration on practice ability cultivation can provide one kind of clear train of thought for the college curriculum adapting even surpassing the demand of this society.

Objective To investigate the effects of warming yang-dispelling turbidity-dredging collaterals method on renal interstitial fibrosis in rats with chronic renal failure caused by 5/6 nephrectomy and explore its mechanisms. Methods Eight rats were randomly chosen as sham operation group (Sham), while the remaining 24 rats underwent 5/6 nephrectomy were divided into model group (5/6Nx), warming yang-dispelling turbidity-dredging collaterals method group (WDD) and Niaoduqing group (NDQ), and the rats in each group were administrated with corresponding drugs. After the intervention of 12 weeks, all the rats were sacrificed and the kidneys were then removed. HE, PAS Masson, Picrosirius red staining were conducted to assess kidney pathological changes and renal fibrosis. The protein expression of Collagen was tested by both immunofluorescence and Western blotting, and the mRNA expression was evaluated using qRT-PCR. The expression of protein related with the process of EMT, including α-SMA, E-Cadherin and Vimentin, were tested with immunohistochemistry and Western blotting. Results Compared with the model group, warming yang-dispelling method alleviated kidney pathological injury and renal fibrosis, and significantly down-regulated the protein and mRNA expression of Collagen . Moreover, warming yang-dispelling turbidity-dredging collaterals method regulated the process of EMT by decreasing the high expression of α-SMA and Vimentin, and increasing the low expression of E-Cadherin. Conclusion Warming yang-dispelling turbidity-dredging collaterals method can effectively attenuate renal fibrosis and injury and its underlying mechanisms may be related with its inhibitory effects on Collagen expression and regulation of EMT.

Some problems were settled in making permanent slide for predacious nematode fungi by slide cultivation and cotton blue stain. Method of small-hole culture covered with slides could obtain high quality images, which solved the problem that trapping device couldn't be observed with high-power microscopes and oil-immersion microscopes. Scraping slide technique improved the method of making temporary slides.

Objective To study the genetic relationship among Dioscorea zingiberensis with different diosgenin content at DNA level.Methods DNA of all types was amplified by 12 random primers from 40 random primers,the polymorphic bands of RAPD were counted.And the results of types were analysed by POPGENE 1.31(Tool for Population Genetic Analysis 1.31) software.Results A total of 73 bands was obtained,64 of total bands(87.67%) was polymorphic.The results indicated that there were apparent and abundant genetic variations in D.zingiberensis. Conclusion The formation and accumulation of diosgenin could be affected significantly by the genetic basis of D.zingiberensis.

Objective To evaluate the effect of TBL (team-based learning) method in pharmacology teaching for the foreign students of clinical medicine. Methods In the course of pharmacology teaching of the foreign students of clinical medicine, TBL method was performed in the 2012-year students and tradi-tional teaching method was performed in the 2011-year students. After the teaching, students' grades in the ordinary performance, their final exam scores and their evaluation of the two teaching methods were com-pared. Graph pad 5 was used to analyze the data and the t test was performed. Results The average ordi-nary performance of the students with TBL was significantly higher than that with the traditional teaching [(84.94 ±12.66) vs. (72.30 ±4.90), P=0.000] and the final examination scores were significantly im-proved [(74.00±6.76) vs. (69.00±6.20), P=0.023]. The survey showed students were more satisfied with the TBL teaching mode than traditional teaching mode [(8.40±0.71) vs. (7.12±1.07), P=0.000]. Conclusion TBL teach-ing mode can effectively improve the pharmacology teaching effect of foreign students.

Dendrobium represents one of the most important orchid genera with ornamental and medicinal values. The stems of Dendrobium species have been used as Dendrobii Caulis in traditional Chinese medicine for a thousand years, which manifest a diversity of medicinal effects including tonic, analgesic, antipyretic, and anti-inflammatory. In recent decades, about 100 compounds have been found and identified from the medicinal parts of more than 40 Dendrobium species, which include polysaccharide, alkaloids, flavonoids, phenols, terpenoids, amino acids, trace elements, coumarin, tanning, sterols, etc. This review focus on main research conducted during the last decade on Dendrobii Caulis and their constituents, which have been studied on their pharmacological effects involving immunomodulatory activities, antidiabetic, anticancer, anti-oxidant, anti-aging, hepatoprotective, anti-inflammatory, neuroprotective, cardiovascular protective, enterogastric strengthening, anti-angiogenesis, allergic dermatitis symptoms improving, antifatigue, antiplatelet aggregation, etc. Simultaneously, the key research problems and the future development on Dendrobium are prospected.

Objective: To study the antipyretic action of Dipseudoephedrine Glycyrrhizin and its effect on heart rate and blood pressure of rats.Methods: The model of pyretic rabbit was established by diphtheria-pertussis-tetanus triple vaccine,and to observe the effect of Dipseudoephedrine Glycyrrhizin on temperature of rabbit. Two-path physiological recorder was used to measure heart rate and blood pressure.Results: The experiment proved that Dipseudoephedrine Glycyrrhizin can decrease the anus temperature of pyretic rabbit obviously.Dipseudoephedrine Glycyrrhizanate had no remarkably effect on heart rate and blood pressure.Conclusion: Dipseudoephedrine Glycyrrhizin has antipyretic action and has no effect on heart rate and blood pressure within studied dose.

Object The immunoregulation function was studied in experimental animals to observe the effect of single and/or combined use with Radix Aconiti (RA) and Radix Stephaniae Tetrandrae (RST). Methods The response of delayed type hypersensitivity (DTH) in mice, the phagocytosis of abdominal macrophages (M?) in mice, and the production of special antibodies in mice were observed. Results The two Chinese materia medica (CMM) in combination use could induce the increasing of phagocytosic function of M? hypoimmunitic model mice, the inhibiting on the responses of DTH in the hyperimmunitic model mice and the non immunosuppressive treated mice. On the production of special antibodies in mice, the enhance effect was found in RA used in single, and the suppressive effect was found when using the combination of the two CMM. Conclusion In accordance with the mechanism of the disorder between the anti inflammation effect and the induce inflammation effect to arthritis in the immune system, these data indicate that the bidirectional effect of combination of the two CMM used on the immune responses, may be the involved mechanism on treating arthritis.

T_4 was coupled to human serum albumin(HSA)to make the conjugate T_4-HSA,a polyvalent T_4 analogue rather than monovalent T_4 per se alone.A new strategy for sandwich enzyme immunoassay model system of small molecular hapten hormones FT_4 was developed,such as intra-assay CV,inter-assay CV,average recovery, normal and abnormal values were fit for clinical application.The sensitivity was as much as 10 times higher than conventional competitive enzyme immunoassay.
