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 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.

Conclusion The formation and accumulation of diosgenin could be affected significantly by the genetic basis of D.zingiberensis.

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.

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.

Objective To evaluate the desflurane-induced sympathetic activation with finger tip perfusion index (FTPl). Methods Forty-eight ASA ⅠorⅡ patients aged 25-60 yr undergoing elective surgery under general anesthesia were randomly divided into 3 groups (n=16 each): groupⅠsevoflurane; group Ⅱ desflurane and groupⅢ desthrane + propofol. Anesthesia was induced with midazolam 0.03 mg/kg, propofol 2 mg/kg and fentanyl 2 μg/kg. Tracheal intubatian was facilitated with vecuronium 0.1 mg/kg. The patients were mechanically ventilated (VT 8-10 ml/kg, RR 12 bpm). PETCO2 was maintained at 35-40 mm Hg. In group ⅠandⅡanesthesia was maintained with sevoflurane and desflurane respectively. The end-tidal concentration of sevoflurane and desflurane were rapidly increased to 0.5 MAC, 1.0 MAC and 1.5 MAC and maintained at each level for 5 rain. In group Ⅲanesthesia was maintained with TCI of propofol and destlurane. The target plasma prepofol concentration was set at 1 μg/ml and the end-tidal concentration was rapidly increased to 0.5 MAC and 1.0 MAC and maintained at each level for 5 mitt. MAP, HR, FTPI and BIS were continuously monitored and recorded at 5 rain after midazolam (T0), 3 rain after induction of anesthesia (T1), immediately after tracheal intubation (T2), as soon as the end-tidal concentration of sevoflurane and desflurane reached 0.5 MAC(T3), 1.0 MAC(T5) and 1.5 MAC(T7) and after being maintained at 0.5 MAC (T4), 1.0 MAC (T6) and 1.5 MAC (T8) for5 rain. The plasma renin activity and the levels of angintonin Ⅱwere determined at T0, T1, T2, T5 and T7 by using radioimmuno-ssay. Results FTPI was significantly lower at T5 than at T4 in group Ⅱ HR and MAP were significantly lower at T4-6 and T8 and FTPI were significantly lower at T3～6 and T0 than at T7 in group Ⅱ. HR and MAP were significantlyhigher while FTPI was lower at T7 in groupⅡthan in group Ⅰ The changes in MAP and FTPI between T4 and T5 were significantly less in group Ⅲthan in group Ⅱ. The time when the highest value of FTPI was maintain was significantly shorter than the time when the highest values of HR and MAP were maintained at T5 and T7 in group ⅡΔFTPI was negatively correlated with ΔHR and ΔMAP (r=-0.593, P<0.05;r=-0.591, P<0.05). Conclusion FTPI can reflect the desflurane-induced sympathetic activation promptly and sensitively.

Objective To discuss the value of color Doppler ultrasonography in the diagnosis and differential diagnosis of urinary tract urothelial carcinoma (UTUC).Methods Color Doppler ultrasonography exam was practiced in 84 UTUC patients preoperatively.According to ultrasound characteristics,lesions was classified into nodular type,wall thickening type and solid mass type,which were confirmed by pathology in all cases postoperatively.Results In the total of 84 cases (76 transitional-cell carcinoma,5 adenocarcinoma and 3 epidermoid carcinoma),lesions infiltrated laminae propria and surrounding tissue in 65 cases.In the nodular type of UTUC,there were nodules raising into lumen.Wall thickening type of UTUC was characterized by irregularly wall thickening,lumen narrowing,truncating and breaking.Similarly,obstruction broke off the ureteral lumen suddenly in solid mass type of UTUC.A clear demarcation could be found between the pipe wall and surrounding tissue in nodular type.However,such clear demarcation could not be found in wall thickening type and solid mass type.The accordance rate of ultrasonographic located diagnosis were 92.9 ％ (78/84),with 6 missed diagnosis cases.The accordance rate of qualitative diagnosis were 89.7％ (70/78).Conclusions As result of color Doppler ultrasonography,there were different relationship between lesion and the peripheral tissue in different types of UTUC.In types of wall thickening and solid mass,the demarcation was unclear and it is easier to violate the surrounding tissue.Color Doppler ultrasonography can provide more effective information for diagnosis and therapy UTUC.
