0.05); the effective rates in rest pain in the two groups were 41.25% and 57.97%,respectively(P

OBJECTIVE:To establish an RP-HPLC method for the determination of Berberine hydrochloride in Keyang-min tincture.METHODS:The sample separation was performed on Agilent Eclipse XDB C18(250 mm?4.6 mm,5 ?m),and the mobile phase was acetonitrile-5 mmol?L-1 perfluorooctane sulfonate(32∶68) at flow rate of 1 mL?min-1.The detection wavelength was 346 nm and the temperature of column was 35 ℃.RESULTS:The linear range of Berberine hydrochloride was 0.059 2～0.888 3 ?g(r=0.999 9).The average recovery rate was 99.71%(RSD=1.18%,n=6).CONCLUSION:The met-hod is sensitive,accurate,and reproducible,and suitable for the determination of Berberine hydrochloride in Keyangmin tincture.

OBJECTIVE:To study the effect of Hordeum vulgare on hormone level in male mice.METHODS:Male mature mice(5～6 months) were treated with Hordeum vulgare decoction 1 mL(equivalent to 0.5 g?mL-1 crude drug) bid for 14 consecutive days.Follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2) and testosterone(T) in blood were monitored.RESULTS:In Hordeum vulgare group compared normal control,serum E2 increased significantly,serum level of testosterone decreased significantly,while FSH and LH levels remained stable.CONCLUSION:Hordeum vulgare can influence the hormone level in male mice by influencing the gonad axis of the mice.

OBJECTIVE:To explore the reason for the "tragedy of anti-commons" in biomedical patent and its effect on the development of biomedical industry.METHODS:The mathematical models of "commons" and "anti-commons" gambling were established based on the analysis on emergence of "patent bush" resulted from the abuse of biomedical patents,and the profit conflict of the patents power related to elementary researcher and applicant researcher was analyzed.RESULTS:The potential "tragedy of anti-commons" affects the enthusiasm of the biomedical researchers,hinders the rapid development of biomedical industry and the improvement of technological level.CONCLUSIONS:The corresponding measures should be taken from aspects such as system,research model,and patent applicant model to balance the possessiveness and exclusiveness,avoid the "tragedy of anti-commons" and facilitate the development of biomedical industry.

OBJECTIVE: To study the bioequivalence of domestic oxcarbazepine dispersible tablets. METHODS: 20 healthy male volunteers were randomly given oxcarbazepine dispersible tablets (test tablet) and oxcarbazepine tablets (reference tablet) via p.o. The plasma concentration of active metabolite (MHD) of oxcarbazepine were determined by HPLC. 3p97 software was used to calculate pharmacokinetic parameters and the bioequivalence of oxcarbazepine were evaluated. RESULTS: After treatment main pharmacokinetic parameters of test tablet vs. reference tablet were as follows: Cmax(4.231?0.841) ?g?mL-1 vs. (4.350?0.861) ?g?mL-1; tmax(4.13?0.43) h vs. (4.28?0.44) h; t1/2(14.17?2.66) h vs. (14.44?2.09) h; AUC0～60 (113.00?22.25) mg?h?L-1 vs. (118.11?14.20) mg?h?L-1; AUC0～∞(126.35?20.94) mg?h?L-1 vs. (130.54?16.17) mg?h?L-1. The relative bioavailability of test tablet to reference tablet was (95.67?12.80)%. CONCLUSION: Two kinds of tablets were bioequivalent.

Objective To understand the plasma Platelet Microparticiles(PMPs)level and its clinical significance in patients with type 2 diabetes mellitus(T2DM).Methods Venous blood samples were obtained from 96 of T2DM patients and 30 of non-diabetic control subjects.PMPs,CD61P positive on platelets,were quantified by flow cytometry.Meanwhile,plasma levels of PLT,FPG,TC,TG,HDL-C,LDL-C and LP(a)were detected,as well as the levels of MA and TRF from urine samples.Results PMPs counts were significantly greater in 2 year or up 2 year groups than in controls.PMPs count was associated with levels of urine MA and TRF,but not related with other indexes.Conclusion PMPs may be a marker of microvascular disease in Type 2 diabetes.

OBJECTIVE:To analysis the application status of antibiotics in perioperative patients of our hospital.METHO-DS:The use of antibiotics in 300 perioperative patients(100 with type Ⅰ incisions and 200 with type Ⅱ incisions)from June to November in 2006 were analyzed retrospectively.RESULTS:In the patients with type Ⅰ incisions,Cephalosporins took the lead on the list of DDDs,followed by Penicillin,Nitroimidazole,FQNS,and Aminoglycosides.CONCLUSION:Physicians should have an increased awareness to the rational prophylactic use of antibiotics in perioperative patients to lower the perioperative infection rate of incisions.

Literatures available was reviewed on the thrombosis and mechanism of new antithrombotic agents.The pathophysiology of the thrombosis involves dysfunction of endothelium and cell adhesion.The new antithrombotic drugs include factor Ⅹa inhibitors, GPⅡb/Ⅲa receptor blocking agents and the drugs modulating the function of endothelium.
