[Objective]To filter and optimize extractive technology of Qianliening granules.[Methods]The optimization extractive technology of Qianliening granules was investigated using orthogonal design with the availability component extracting from the drug as the index.[Results]The optimal condition for the extraction of Radix Astragali group was 10 folds amount of water,3 times,1.5 hours each time.The optimal condition for the extraction of Rheum officinal Baill.group was 6 folds amount of 60% alcohol,2 times,two hours and 1.5 hours each time.[Conclusion]The optimized extractive technology is scientific and efficient.

Objective To establish nude mice xenograft tumor models of human endometrial carcinoma for basic and clinical study. Methods Fourteen samples of human endometrial carcinoma were subcutaneously heterotransplanted to nude mice (BALB/C, nu/nu),3~4 mice were transplanted for every sample. Results The initial take rate was 42.8%,then it increased to 100.0% after the 5th passage. Five of 14 samples were transplanted for 48~63 passages.The characteristics of histology,ultrastructure and chromosome were identical to those of human donour tumors. The DNA ploidy was consistent for SL-1,SL-2 and SL-3,but changed for SL-4 and SL-5 by cytometric analysis. The expression of estrogen receptor and progesterone receptor for 5 models was all negative. The expression of p53 was positive for SL-1,SL-2 and SL-4,but negative for SL-3 and SL-5.The expression of c-erbB-2 was positive for SL-1,SL-2 and SL-4,negative for SL-3 and SL-5.The expression of p16 was positive for SL-2 and SL-3,negative for SL-1,SL-4 and SL-5. Conclusions Five nude mice xenograft tumor models of human endometrial carcinoma were established successfully. It will be helpful for the basic and clinical study of human endometrial carcinoma.

OBJECTIVETo investigate the anti-apoptosis effects of Rubus alceaefolius total alkaloids in rats with hepatic injury.
METHODThe hepatic injury model of rat was induced by intraperitoneal injection with CCl4. Sixty SD rats were randomly divided into the normal group, the model group, the R. alceaefolius total alkaloids intervened group, and the bifendate intervened group. The expressions of the levels of liver cell apoptosis were determined by TUNEL. Ultrastructures of the liver cells were observed with transmission electron microscope.
RESULTCompared with the model group, the degree of hepatic injury and the positive expressions of apoptosis in liver tissues in the R. alceaefolius total alkaloids intervened groups and the bifendate intervened group were significantly lower.
CONCLUSIONR. alceaefolius total alkaloids could reduce the pathological changes and degree of hepatic injury in rats, which may be partially through inhibiting the expressions of apoptosis in liver tissue.
