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.

Objective:To establish a microwave digestion and inductively coupled plasma mass spectrometry(ICP-MS)for determination on calcium content of Xiao'er Magan granules and discuss the effect of decocting gypsum into medicine on calcium content.Methods:ICP-MS was adopted to determine the calcium content in the preparation,and the difference of calcium content in the small preparation and Xiao'er Magan granules prepared by different pul-verization degree gypsum and different alcohol precipitation processes were compared.Results:The consistency of calcium content between different enterprises and batches of the same enterprise was poor.The results showed that the larger the particles,the lower the calcium transfer rate.The smaller the particles,the higher the calcium trans-fer rate.Conclusion:The transfer rate of gypsum decocted calcium is related to its degree of comminution to ensure consistency of preparation quality.It is suggested to unify the comminution degree of gypsum.The method can pro-vide guidance for the optimization on preparation technology of Xiao'er Magan granules.

Objective To analyse the quality of Xiao'er Magan granules by the combination of chemometrics and difference analysis of component content.Methods The ultra-performance liquid chromatography/quadrupole time-of-flight-tandem mass spectrometry(UPLC-Q-TOF/MS)method was used to study the characteristic spectrum of basic components.The partial least squares discriminant analysis was used to quantify and screen the markers of quality difference,the methods of muti-component quantification for differential components and fingerprint were established,and the principal component analysis was used to calculate the comprehensive scores of principal components.Results The 12 common peaks were identified by the characteristic spectrum,which were attributed to 6 medicinal herbs,namely Rhizome,Mulberry bark,Bitter almond,Licorice,Perilla seed and Scutellaria.Taking the variable importance projection value＞1 as the criterion,4 characteristic components of quality differences(mulberry A,amygdalin,rosmarinic acid and baicalin)were screened out.The fingerprints similarity of 45 batches of samples were 0.867-0.997.14 components were calibrated,and 8 components were identified,which were mulberroside A,L-amygdalin,amygdalin,rosmarinic acid,baicalin,oroxindin,baicalein and wogonin.The scores of principal component 1 of each enterprise were as follows:G＞H＞A＞C＞E＞D＞F＞I＞B.The scores of principal component 2 were as follows:F＞G＞H＞B＞E＞D＞C＞A＞I.The ranking of the comprehensive scores was as follows:G＞H＞C＞A＞E＞F＞D＞I＞B.Conclusion The preparation quality of enterprise G and H is the best.The established fingerprint and quantitative method of quality differential components are accurate and reliable,which can provide reference for the quality analysis of Xiaoer Magan granules.
