Objective To study the qualitative analysis and quantitative analysis of flavonoids and other ingredients in leaves of Lonicera hypoglauca miq,and to optimize the reflux extraction condition for total flavonoids from leaves of lonicera hypoglauca miq. Methods Preliminary test was used for qualitative analysis. UV-spectrophotometry was used to determinate content of total flavonoids. By orthogonal design,the extraction rate of flavonoids was determined in different factors of ethanol reflux extracting. Results Leaves of lonicera hypoglauca miq contained alkaloids and flavonoids.The optimum conditions of ethanol reflux extracting total flavonoids are 12 times 50% ethanol,and refluence for 1.0h at water bath for two times.According to validate experiment,the average total flavonoids content was 16.6% in leaves of lonicera hypoglauca miq,with RSD=1.52%(n=3). Conclusion Flavonoids are in higher level in leaves of Lonicera hypoglauca miq. There are some chemical similarity in leaves of lonicera hypoglauca miq and leaves of flos lonicerae.

OBJECTIVE:To investigate the clinical efficacy and safety of atorvastatin calcium combined with probucol in the treatment of atherosclerosis. METHODS:A total of 80 patients with atherosclerosis selected from the Affiliated Hospital of Sichuan College of TCM during Jan. 2015-Jan. 2016 were randomly divided into control group and observation group according to random number table,with 40 cases in each group. Control group was given Probucol tablet 0.5 g,every 2 days. Observation group was ad-ditionally given Atorvastatin calcium tablet 20 mg,qd,on the basis of control group. Both groups were treated for consecutive 24 weeks. The levels of blood lipid,arterial plaque size and thickness before and after treatment,life quality score before treatment and 3 months after treatment were observed in 2 groups;and the occurrence of ADR was recorded. RESULTS:Before treatment, there was no statistical significance in blood lipid,arterial plaque size and thickness or life quality score between 2 groups(P>0.05). After treatment,the levels of TC,TG and LDL-C,arterial plaque size and thickness in 2 groups were decreased significant-ly,while HDL-C level and life quality score were increased significantly;the improvement of above indexes in observation group was significantly better than control group,with statistical significance(P<0.05). There was no statistical significance in total inci-dence of ADR between observation group(12.50%)and control group(15.00%)(P>0.05). CONCLUSIONS:Atorvastatin calci-um combined with probucol in the treatment of atherosclerosis can reduce blood lipid level and get thrombolysis,and contribute to the recovery of living ability with good safety.

Objective To study the influence of different routes of keyhole limpet hemocyanin ( KLH) immuniza-tion on the T-cell-dependent antibody response in mice.Methods SPF Kunming mice were divided into four groups: the intravenous injection group, subcutaneous injection group, intraperitoneal injection group and control group.Each mouse was injected 200 μg KLH intravenously, subcutaneously or intraperitoneally daily for consecutive 10 days, respectively. Mice in the control group were given solvent injection only.Serum concentration of IgG stimulated by KLH antigen was measured 7 days after the last dosing.Spleen was isolated to calculate the organ coefficient and examined by pathology u-sing hematoxylin and eosin staining.Results Intravenously, subcutaneously and intraperitoneally administered KLH stimu-lated the generation of secondary lymphoid follicles and germinal center to varying degrees, B cell apoptosis, increased a-mount of cells in the marginal zone and other pathological changes were observed in the spleen.Intravenous and intraperito-neal administration of KLH led to more pronounced pathological changes compared with that in the subcutaneous injection group.All of the three administration routes of KLH induced generation of IgG antibody, significantly higher than that in the control group (P<0.05).Intravenous injection of KLH generated the highest concentration of IgG and organ coefficient among the three administration routes ( P<0.05) .Conclusions Different immunization routes do affect the production of IgG antibody, organ coefficient and pathological changes in the spleen, and these differences should be taken into consider-ation when analyzing the T cell dependent antibody response in mice.

Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0％ of Child A patients,50％ in Child B patients,41.6％in patients with a MELD score below 14,and 91.7％ in patients with a MELD score of ＞ 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P ＜ 0.05),while that between patients with Child-Pugh A and B was insignificant (P ＞ 0.05).The incidences of postoperative liver dysfunction in patient with a MELD ＜ 8,8 ≤ MELD ≤ 14,MELD ＞ 14 were 38.2％,57.6％ and 91.7％,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P ＜ 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P ＜ 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score ＞ 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score ＞ 14 requires active preoperative preparation,bringing the score near to or less than 14.
