Ethyl acetate extract of Tripterygium wilfordii (20mg/kg, 40mg/kg ), given to adjuvantarthritis rats (ig ) for 7 consecutive days, markedly decreased both high and low shear whole blood viscosity, plasma viscosity, whole blood reduction viscosity, hematocrit and fibrinogen content, but without effect on blood sedimentation and K value in blood sedime ntation equation. These resuits indicated that the decreasing effect of T. wilfordii on bloodviscosity ma y be related to ius influenee on red blood cells and plasma composition.

OBJECTIVE: To observe the effects of astragalus polysaccharides(APS) combining with total ginsenoside (TG) on the proliferation of T cells in peripheral blood of healthy adults and on the immune function of mice after treatment with cyclophosphamide (CY) . METHODS: The proliferation rate of T cells in peripheral blood was detected by methyl thia-zolyl tetrazolium(MTT) colorimetric analysis; the weight of immune organs such as spleen and thymus etc. in mice were detected. RESULTS: The proliferation of T cells in human peripheral blood could be enhanced if the concentration of APS remained within 25-100?g/ml and that of TG remained within 5-20?g/ml; the proliferation rates were 102.3%-141.1% and 113.9%-163.1% , respectively; the figure stood at 262.3%-383.0% when APS and TG used in combination. The spleen indexes of APS group and the APS plus TG group increased significantly vs. the CY group(P

Traditional treatments for malignant tumor are far from meeting the clinical demands.Recently,research on anti-tumor targeted drugs has made a significant breakthrough,which brings new hope for the treatment of malignant tumor.Anti-tumor targe-ted drugs can specifically target malignant tumor and directly in-hibit the growth of tumor cells,showing no toxicity to the normal tissues and organs.Herein we reviewed the research progress of small molecular targeted drugs and antibody targeting new drugs.

OBJECTIVE: To establish an HPLC method for the determination of fumaric acid in Pleurotm citrinopileatus. METHODS: HPLC was performed on Yilite C18 column(250 mm?4.6 mm,5 ?m) with methanol-0.01 mol?L-1 potassium dihydrogen phosphate solution(5 ∶ 95,pH adjusted to 2.5 using phosphoric acid) as mobile phase and detection wavelength of 216 nm. RESULTS: The linear range of fumaric acid was 0.16~1.6 ?g (r=0.999 9). The average recovery was 101.59% (RSD=1.28%,n=6). CONCLUSION: This method is accurate, simple and reproducible for the content determination of fumaric acid in P. citrinopileatus.
