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.

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

Objective In order to explore the effective dosage of insulin and its correlated elements in sulphonylureas failure in type 2 diabetes mellitus.Methods 61 cases of type 2 diabetics were separated into two groups,one group (group 1) is the first time using insulin and the other group (group 2) is in the use of insulin in the past.Results The effective insulin dosage of group 2 is significantly higher than that of group 1 (36.2?10.6 IU/d vs 30.1?10.5IU/d, P

Objective To observe the effect of Maiya on the hormone level of the female mice. Methods Female mature mice (5 ～ 6 months) were ovariectomized and treated with Maiya. Follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and progesterone (P) in blood were examinated. Results Maiya could increase the FSH and E2 in blood, and decrease P in blood of the castrated mice, while the level of LH had no obvious change. Conclusion Maiya can influence the level of hormone.

This paper analyzes the reform backgrounds, mechanisms and measures of financing and payment taken in the second-generation national health insurance (NHI) in Taiwan. The results indicate that in 2nd NHI, the rate was adjusted more flexibly, supplementary insurance premium was charged to enlarge the financial source by im-plicating additional subsidies and expanding the sources of financing, multiple payment methods and auxiliary assis-tive means were used to control the growth of medical expenses, social insurance payments are specified in terms of category or clear payment projects and standards, new health technology assessments are used as new basis for deci-sion making, etc. by greatly alleviating the financial deficit, which helped achieve the financial balance again. Many features of the 2nd NHI in Taiwan, especially like its diversified financial resources and financing methods, global budget of control fees and DRGs payment systems, making evaluation criteria for medical quality control and health insurance reimbursement project development and so on, are worth learning for the mainland China.

Objective To investigate the therapeutic effects, duration of hematopeietic depression and side effects of FLAG regimen for refractory and relapsed acute myeloid leukemia(AML). Methods 13 cases for 5 days, and granulocyte colony stimulating factor G-CSF 300 μg/d from day 0 till neutruphil recovery (ANC≥1x109/L). 13 patients were 8 males and 5 females. The median age was 41.8 years(range 28-67). It includes 5 relapsed AML patients and 8 refractory AML patients. Results Of the 17 times, 11 showed response to therapy; the rate of complete remission was 35.3 %(6/17); the rate of partial remission was 29.4 % (5/17) and the overall response rate was 64.7 %. Main toxicities were gastrointestinal side effects, myelosupression and the function of liver was lightly damaged. Neutropenia at lowest number began at the time of 5-12 days after regimen initiating and last 7-34 days, thrombocytopenia began at the time of 5-13 days and last 8-30 days. Conclusion FLAG regimen showed obvious effects for refractory and relapsed AML Most patients gained chance for hematopoietic stem cell transplantation. Hemotological and nonhemotological toxicities are acceptable.

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.

Objective To find out the status of nosocomial infection management in hemodialysis sections, in order to encourage their continuous quality improvement and standardize their management Methods 41 hemodialysis sections with (≥) 3 dialyzers and independent operation were chosen for investigation. On-site investigation and environmental microbiology monitoring combined. Results The higher the level of the hospital, the better the nosocomial infection control in its implementation of the infection control measures. In terms of rules and regulations, incompliant secondary hospitals and private hospitals accounted for 56. 2% of hospitals of the same ranking; in terms of layout and processes, 75% are found incompliant; and various defects are found in the dialyzer reuse management and disinfection in tertiary and lower hospitals. As to hand hygiene of the staff, the incompliance rate is over 55%. As indicated in the results of microbial environment monitoring, the compliance rate of dialysis water is over 90%, that of dialysate is 78.6% ～ 86.2%, and that of hand disinfection is 56.6%～78.6%.Conclusion It is imperative to strengthen the supervision of secondary hospitals and private hospitals,and to train their staff in the knowledge of hand hygiene and nosocomial infection in hemodialysis rooms.Hospitals found with poor infection management will be encouraged to take issue-specific actions for rectification.

Purpose To study the spiral CT (SCT) appearances of pleural plaques,to improve the accuracy of diagnosis and differential diagnosis,and to evaluate clinic application.Materials and Methods The SCT appearances in 42 cases with pleural plaques were analysed retrospectively,which closed met with asbestos dust.Results SCT showed 407 pleural plaques in 42 cases,of which there were hyline / uncalcified pleural plaques (n=250),calcified pleural plaques(n= 36),mixed pleural plaques(n=121);unilateral pleural plaques (n=10),bilateral pleural plaques (n=32);single pleural plaque in 5 cases,multiple pleural plaques in 37 cases.The largest pleural plaque was 4.2cm×1.2cm.There were a lot of shapes of the pleural plaques.Various shapes of calcifications could be showed in the calcified or mixed type pleural plaques.The pleural plaques distributed in the middle-inferior part,anterior / posterior-lateral chest wall,underlying the ribs in 28 cases (66.6 %),both bilateral domes of diaphragm in 10 cases and mediastinal pericardium in 4 cases.The pleural plaques associated with pulmonary intertitial fibrosis in 4 cases.No cases in the apices / costophrenic angles.No enhancement of pleural plaques in 6 cases which were administrated contrast scan.Conclusion SCT can clearly show the distribution,extention,shape,size,density and relation to adjacent tissues of the pleural plaques,and with asbestos exposure history,can make a diagnosis and differential diagnosis from other pleural thickened lesions.SCT is the best choice of imaging methods for asbestosis and pleural plaque.
