AIM: To establish the quality standard for Kangmailing Capsule(Ginkgo Biloba extract, Rhizoma Gastrodiae, Rhizoma Chuanxiong). METHODS: The flavone glycoside content in Kangmailing Capsule was determined by HPLC. Waters ? bondapak C 18(3.9 mm?300 mm, 5 ?m) column was used. The mobile phase was metanol-0.4%H 3PO 4(50∶50), and UV detection wavelength was at 360 nm. Rhizoma Gastrodiae, Rhizoma Chuanxiong, Ginkgo Lactone and Ginkgolic acid in Capsules were identified by TLC. RESULTS: The calibration curves of Quercetin, Kaempferol and Isorhamnetin were linear at the range of 0.150 ?g-1.50 ?g, 0.142 ?g- 1.42 ?g and 0. 096 ?g-0.96 ?g, respectively. The average recovery was all 98.9%, and RSD was 0.98%, 1.15% and 1.57% (n=5). The TLC sports developed were fairly clear, and the blank test showed no interference, the quantitative limitation of Ginkgolic acid was controlled under 5 mg?kg -1. CONCLUSIONS: The established method is accurate,reliable and specific. The results are stable with good reproducibility. The quality of the capsules can be controlled by the method.

Liver fibrosis is an important pathological hallmark in the early stage of chronic liver injury,which can be gradually treated by drug treatment.Traditional medicine has limited therapeutic effect and is toxic to the normal organs.The drug delivery system based on nanotechnology can overcome the deficiency of traditional drugs to protect the drug which can be delivered to the target cells.Four major types of cells in liver play critical role in liver fibrogenesis,including hepatocytes,hepatic stellate cells,kupffer cells and hepatic sinusoidal endothelial cells.Liver targeted nanomedicine can be delivered to these liver cells based on their material and functional modification and enhance anti-inflammatory and anti-fibrotic effect.They also can reduce the toxic side effects and reverse liver fibrosis.This article gives an overview on current strategies of the application of nanotechnology in targeting treatment for liver fibrosis.

Objective To compare the differences of safety and immunogenicity of DTaP-IPV-Hib-HepB hexavaccine,DTaPIPV-Hib pentavaccine plus HepB single vaccine or DTaP-IPV-HepB pentavaccine plus Hib single vaccine,so as to provide a reference for the marketing and use of hexavaccine in China.Methods Randomized controlled trials(RCTs)of DTaP-IPVHib-HepB hexavaccine,DTaP triple vaccine,Hib,IPV and HepB vaccines published at home and abroad were searched.The safety and immunogenicity of the hexavaccine were evaluated by Meta-analysis using Revman 5.4.1 software.Results A total of 7 articles,8 RCTs and 3 429 subjects were included. Meta-analysis of safety showed that there was no significant difference in the incidence of injection site and systemic adverse reactions after vaccination with hexavaccine and pentavaccine plus single vaccine(P > 0. 05)except for induration at the inoculation site and crying. Meta-analysis of immunogenicity showed no significant difference in antibody indexes after vaccination with hexavaccine and pentavaccine plus single vaccine(P > 0. 05).Conclusion The safety and immunogenicity of DTaP-IPV-Hib-HepB hexavaccine in basic immunity was comparable to that of the control vaccine,and might be applied to infants and young children to prevent related diseases. However,due to the limitations of the quantity and quality of included studies,the above conclusions still depend on the further development of larger sample,multicenter and high-quality

Objective:To investigate the dependence of geometric efficiency (GE) on beam collimation and tube voltage.Methods: The dose profile was measured under the conditions of different collimations and tube voltages and GE was calculated.Results: GE was found to be from 11% to 68%, GE at central position and periphery were found to range from 11% to 49% and 16% to 68% respectively, and weighted GE was found to be from 17% to 58%. GE was increased with beam collimation, while it was less pronounced on tube voltages.Conclusion:The dependence of GE on collimation was significant. Therefore, operators should choose appropriate collimations to reduce the dose burden of patients in CT examinations.

OBJECTIVE:To observe clinical efficacy and safety of Ginkgo biloba extract combined with olmesartan me-doxomil in the treatment of essential hypertension,and to discuss its effect on the expression of serum protein. METHODS:98 pa-tients with essential hypertension were selected and randomly divided into observation group A and observation group B,with 49 cases in each group;40 healthy volunteers were included in control group. Observation group A was given Olmesartan medoxomil tablet 20-40 mg,po,qd;observation group B was given Olmesartan medoxomil tablet 20-40 mg,po,qd+ Extract of G. biloba leaves tablet 40-80 mg,po,bid. Treatment course lasted for 4 weeks. Blood pressure(SBP and DBP),TCM symptom score,the repeti-tiveness and resolution ratio of 2-DE spectrum,protein differentiation expression point,related information of differentiation expres-sion protein in 3 groups and ADR of observation group were observed. RESULTS:After treatment,SBP,DBP and TCM symptom score of observation group were significantly lower than before;those indexes after 4 weeks of treatment were significantly lower than those after 2 weeks after treatment;the observation group B was significantly lower than the observation group A,with statisti-cal significance(P<0.05). The repetitiveness and resolution ratio of protein differentiation expression point in observation group B were significantly better than in observation group A after treatment. The expression of 15 protein points in observation group down-regulated before treatment,and up-regulated after treatment to different extents;the observation group B was closer to control group,compared to observation group A. The expression of 6 protein points up-regulated,and then down-regulated to different extent after treatment;the observation group B was closer to control group,compared to observation group A. A total of 11 protein points were identified. There was no statistical significance in the incidence of ADR between observation group A and observation group B (P>0.05). CONCLUSIONS:G. biloba extract combined with olmesartan medoxomil greatly influences the expression of serum pro-tein in patients with essential hypertension and shows good antihypertensive and pressure-control effects with good safety.
