Objective To establish a method for quality control of Shenbo Fuyanning suppositories. Methods Sophorae flavescentis Radix, Rhizoma dioscoreae Hypoglaucae, and Cnidii fructus were identified by thin layer chromatography ( TLC) , and the content of berberine hydrochloride was determined by HPLC. Results The TLC spots were clear and the negative control had no interference.Berberine hydrochloride had a linear relationship in the range of 0.079-0.790 μg, and the average recovery was 99.3%(RSD=0.70%,n=6). Conclusion The method is accurate, reliable and feasible, and can be used in the quality control of the Shenbo Fuyanning suppository effectively.

Objective To investigate the effects of gemcetabine and LY294002 monotherapy or combination on the proliferation and poptosis of pancreatic cancer cell lines BxPc-3 and MiaPaCa-2.Methods Cell proliferation and poptosis were detected by MTT and Annexin V-FTTC,respectively.Results Both gemcetabine and LY294002 could inhabit the proliferation of the two cell lines.Their inhibitory effects were increased accompanied with increased drug concentrations and the cell survival rates was negatively correlated with logarithmic of the drug concentrations (r＜-0.95,P＜0.01).The inhibitory effects of gemcetabine and LY294002 to the BxPc-3 proliferation were significantly stronger than to the MiaPaCa-2(P＜0.05).For BxPc-3 and MiaPaCa-2,the IC50 of gemcetabine were(10.07±1.83),(36.45±2.71)μmol/L(P＜0.05),and the IC50 of LY294002 were(7.84±1.48),(17.89±1.98)μmol/L(P＜0.05),respectively.Gemcetabine and LY294002 could induce cell apoptosis(P＜0.01).Though both the concurrent or consecutive use of these two drugs could promote cell apoptosis,the effect of the concurrent group was significantly stronger(P＜0.05).The order of these two drugs in the concurrent group had no significant influence on their effects(P＞0.05).Conclusion Both gemcetabine and LY294002 could inhibit the proliferation of pancreatic cancer cell lines.Their concurrent application shows a significant inhibitory effect on the cell apoptosis.
