Objective Observing the clinical effect of Ligustrazine Phosphate Tablets combined with percutaneous intratumoral injection of lipiodol THP on advanced hepa-tocellular carcinoma.Methods83 patients with advanced hepatocellular carcinoma from January 2012 to September 2014 were analyzed.Double-blind, randomized method All patients were divided into the control group 41 cases and observation group 42 cases.The control group were treatedwith percutaneous transhepatic intratumoral injection of lipiodol THP, the observation groupwere given Ligustrazine Phosphate Tablets combined with percutaneous intratumoral injection of lipiodol THP to treat.After treatment, the two groups of patients with treatment efficacy, adverse reactions and Karnofsky and prothrombin time were analyzed.ResultsAftertreatment, the efficacy of the two groups of patients were compared, the results showed that patients in the observation group total effective rate of the control group (χ2=4.034),the difference was statistically significant (P<0.05);two groups adverse reactions in patients after treatment were compared, liver pain, blood toxicity, fever, gastrointestinal reactions similar proportion of patients, the difference was not statistically significant;Theproportion of patients in the observation group AFP<8.1ng/mL was significantly higher (χ2=4.338), the difference was statistically significant (P<0.05);patients were observed after treatment Karnofsky score was significantly higher, the difference was statistically significant (t=7.141, P<0.05);after two groups of patients were compared prothrombin time, the difference was not statistically significant.ConclusionHepatic arterial chemoembolization and percutaneous intratumoral injection of THP lipiodol emulsion on the basis of the combination of Ligustrazine Phosphate Tablets can effectively improve the efficacy of treatment, and has good security, which is a safe and effective methods of treatment should be to promote and use in clinical.

Objective:To develop an HPLC method for the content determination of paeoniflorin, tetrahydropalmatine and osthole in Gujinwan capsules. Methods:The determination was performed on an Eclipse XDB-C18 column (250 mm × 4. 6 mm,5 μm) with the mobile phase consisting of 0. 1％ phosphoric acid (adjusting pH to 6. 6 with triethylamine)-acetonitrile with gradient elution. The flow rate was 1. 0 ml·min-1 . The column temperature was 30 ℃. The detection wavelengths were set at 230 nm and 280 nm. Re-sults:The calibration curves were found to be linear within the range of 9. 56-33. 65 μg· ml-1 for paeoniflorin(r=0. 9998), 3. 65-12. 86 μg· ml-1for tetrahydropalmatine(r=0. 9999) and 5. 81-20. 45 μg· ml-1for osthole(r=1. 0000). The average recovery of paeoniflorin, tetrahydropalmatine and osthole was 98. 8％(RSD=1. 1％), 98. 4％(RSD=0. 8％) and 99. 1％(RSD=1. 4％)(n=6),respectively. Conclusion:The method is simple, accurate and reproducible, which can be used for the quality control of Gujinwan capsules.

Objective To study the hypoglycemic activity of semen Trichosanthis oil(STO) and the mechanism on dia-betic mice .Methods The alloxan-induced diabetic mice were divided into different groups and given different dose of STO by gavage for 4 weeks ,the changes of body weight and fasting blood glucose were investigated every week .Blood serum was drawn to determine TC ,TG ,NO ,NOS and insulin .In addition ,the effect of STO on glucose tolerance were also investigated in alloxan-induced diabetic mice .Results STO can dose dependently reduce the levels of blood glucose and increase the body weight when it was administrated orally at 5 ,10 ,20 ml?kg -1 ,can increase insulin and lower TC ,TG ,NO ,NOS in blood ser-um ,and also can improve glucose tolerance in alloxan-induced diabetic mice .Conclusion STO may potentiate the hypoglycemic effect ,and can improve glucose tolerance .The hypoglycemic activity of STO may be related with increasing insulin and decrea-sing NO and NOS in blood serum .

Objective:To study the content of polysaccharide and its antitumor activity in the edible part and the disused part of asparagus. Methods:A orthogonal design of 4 factors and 3 levels was applied to optimize the solvent concentration, solid-liquid ratio, extraction duration and temperature that influencing the extraction efficiency. The difference in the polysaccharides content between the two parts was compared, and the difference in the antitumor activity against MCF-7 cells was observed with SPSS software. Results:The optimum extraction technology was used. The difference in the polysaccharide content between the edible part and disused part of asparagus was significant (P0. 05). Conclusion:There is significant difference in the content of polysaccharide in the edible part and the dis-used part of asparagus, however, there is no significant difference in the antitumor activity in the two parts of asparagus.
