[ Method ] Based on the single-factor experiment, with polysaccharide content and polysaccharide yield as indices, various factors affecting polysaccharide yield from Radix Glehniae root bark were investigated by central composite design-response surface method. Mo- reover, immune functions of cyclophosphamide-induced blood-deficient mice in various polysaccharide groups were compared to investigate the effects of root bark removal of Radix Glehniae on medicinal quality. [ Result] Ultrasonic extraction was the appropriate extraction technology of polysaccharides from Radix Glehniae root bark. The optimal ultrasonic extraction conditions were ultrasonic time 36 min, ultrasonic power 460 W, solid-liquid ratio 1： 10, ethanol concentration 80%, under which polysaccharide yield reached 16.08%. Polysaccharides extracted from Radix Glehniae root （ALP） and Radix Glehniae root bark （BLP） could effec- tively improve immune function of blood-deficient mice with no significant differences. [ Conclusion] Radix Glehniae could be used without removal of root bark. The optimized extraction process was stable and feasible, which laid a solid foundation for further comprehensive development and utilization of Radix Glehniae root bark.展开更多

Method: Normal human bronchial cell line 16 HBE and lung cancer cell line SK-MES-1 were cultured in vitro. Radix Glehniae extract was prepared to treat the two kinds of cells. The proliferation ability of 16 HBE cells was determined by CCK-8 assay. The migration and invasion abilities of SK-MES-1 cells were determined by Transwell and Matrigel assays, respectively. The expression of TIMP2 m RNA in SK-MES-1 cells was detected by fluorescence quantitative PCR(q-PCR). The secretion level of TIMP2 protein by SK-MES-1 cells was measured by ELISA experiment. Results: Radix Glehniae extract caused no toxic effects on 16 HBE cells at the concentrations of 1 mg/ml to 15 mg/ml. Radix Glehniae extract(from 5 mg/ml to 15 mg/ml) significantly inhibited SK-MES-1 cell migration and invasion abilities, as well as upregulated TIMP2 m RNA expression and enhanced TIMP2 secretion by SK-MES-1 cells. Conclusion: Radix Glehniae can inhibit the migration and invasion behaviors of lung cancer cells by upregulating TIMP2 expression and secretion.展开更多
