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.

The broad application of phacoemulsification and multifocal intraocular lens (MIOL)implantation have been raising concern in postoperative visual outcomes due to the innate shortage of MIOL in design,which will probably results in the decline contrast sensitivity or/and some abnormal optical symptoms following the surgery.Optimizing visual outcomes of MIOL implantation and controlling adverse effects has been become the issue of focus for ophthalmologists,which is being discussed in details,e.g.patient selection,preparation of surgery,surgical techniques,etc.,in the following monograph.

Objective]Observe the clinical effect of early herpes zoster which were treated by venesection ventouse combined with helium-neon laser and drugs. [Methods]The control group 32 cases used Famciclovir Tablet,transfer factor capsules,mecobalamin and acyclovir cream-drug for external use. While the experimental group 32 cases used Famciclovir Tablet,transfer factor capsules,mecobalamin and acyclovir cream-drug for external use. While the experimental group besides taking above-medicine, were treated with venesection ventouse and helium-neon laser at the pathological change. [Results]The control group used to cure for an average of 13 ±2.5 days. The experimental group used to cure for an average of 9.6 ±2.4 days. There were significant differences(P<0.05). [Conclusion] Early herpes zoster treated by venesection ventouse combined with helium-neon laser and drugs, can significantly shorten the duration of symptoms, alleviate suffering, and has good clinical efficacy.

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.

In this study, a literature review was adopted to specify terminology of biosimilars and demonstrate the basic characteristic of biologics and relevant research and development ( R&D) procedures. The regulatory frame-work of the European Medicines Agency ( EMA ) guidelines on biosimilars was introduced. Explicitly, regulatory guidelines and scientific principles, regarding biosimilarity, safety and immunogenicity, extrapolation, labels and names, data protection, were systematically introduced, as well as interchangeability and pharmacovigilance, respec-tively. The purpose of the study is to provide regulatory references for Chinese legislators and recommendations on the R&D of biosimilars in the biopharmaceutical industry.

Aim To establish and evaluate a mouse model of my-ocardial fibrosis by hypodermic injection of isoprenaline. Meth-ods Kunming mice were randomly divided into 2 groups, namely, the myocardial fibrosis model group and the control group, 10 mice in each group. The mice in the model group were given isoprenaline 5 mg · kg-1 by hypodermic injection. From the following day, the dose of isoprenaline was reduced to 2. 5 mg·kg-1 , and lasted for 30 days. The mice in the control group were treated with the physiological saline in the same way. Final-ly, heart weight was then weighed and the cardiac weight index (CWI) was calculated. Hydroxyproline (Hydro) level in myo-cardium was determined by a colorimetric method. HE and Mas-son’s trichrome staining were used to estimate the extent of myo-cardial fibrosis and calculate the collagen volume fraction ( CVF) . RT-PCR was used to measure the myocardial Collagen I mRNA expression. Results Compared with the control group, the CWI and Hydro content in the myocardial tissues in the model group were increased(P<0.01). The content of col-lagen in the myocardial tissues and the CVF were increased obvi-ously(P<0.01). The RT-PCR results showed that the left ven-tricle Collagen I mRNA expression in the model group increased obviously( P<0.01 ) . Conclusion Isoprenaline-induced myo-cardial fibrosis model has been established and the method is very simple, economic and reliable.
