Objective To discuss the probability of extracting the effective part of Yinhuang prescription with membrane separation method. Methods To extract and concentrate Yinhuang decoction with amb-class UF and first class NF, baicalin and chlorogenic acid were detected with HPLC, and polysaccharide with anthrone agent colorimetry. Results The content of polysaccharide in final membrane fraction was 3.41 mg/mL. The diversion ratio of baicalin and chlorogenic acid from primal decoction was 77.24%, 79.02%. Conclusion The effective part of Yinhuang decoction can be extracted with membrane separation method. Multiple active components including polysaccharide were retained and the method is simple.

Objective To optimize the water extractive process of Guben Zhike Electuary. Methods To arrange experiments with uniform design for optimizing suitable extractive proces, with the content of polysaccharide and astragaloside Ⅳ as the detecting indexes, inspecting the extacting times, lasting time and additional water which would affect the extraction rate of the two effective components. Result The best process was that water as extraction solvent, extracted for three times with two hours each time, and the amount of water added up to nine times of herbs. Conclusion The best process could extract most of the effective components out of the herbs, which is scientific.

Objective To discuss the effects of silencing of iASPP gene on human bladder cancer cells. Methods RNAi silencing of iASPP gene in bladder cancer cell 5637 and T24 cells were used by lentiviral mediated interfering short hairpin RNAs. Cell proliferation was tested by MTT assay, and rate of colony was tested by colony formation assay. Cell cycles were tested by using fluorescence-activated cell sorting. Results Down-regulation of iASPP could inhibit the growth and proliferation of human bladder cancer cells (P＜0.05). iASPP know-down could decrease the colony formation of 5637 and T24 cells (P＜0, 05). Knocking down of iASPP in 5637 and T24 cells showed cell arrested at G1. Conclusions Silencing of iASPP gene could inhibit proliferation and colony formation of bladder cancer, iASPP might be an important target for gene therapy of bladder cancer.
