Objective To investigate the current policy of medical insurance expenditure control in Shanghai and put forward feasible advice. Methods Survey in 5 tertiary first-class hospitals in Shanghai involving 400 doctors and patients was conducted.The result of the questionnaire was tracked with Microsoft Excel 2000.The expense reports during 2001 to 2006 from the Office of Medical Insurance of Shanghai Renji Hospital was collected.All the data were statistically analysed. Results The global budget system was accepted by both the doctors and patients.Charging based on disease categories was proved a relatively satisfying method.Drug expenditure control was concerned by both the doctors and patients. Conclusion Ever since the global budget system of medical insurance is implemented in Shanghai,the medical insurance expenditure has been effectively controlled.The key point is the restraint of irrational consumption during the medical treatment.

Objective: To establish a HPLC method for the determination of ginsenoside Re、Rg1 in Yianhuisheng Oral Liquor(Radix Ginseng Rubra, Radix Aconiti Lateralis Preparata, Scorpio etc.) Methods: RP-HPLC was used to quantitative analysis. The Synchropak C 4 column (250mm?4.6mm, 5?m) was used, and mobile phase was composed of acetonitrile-0.05% H 3PO 4(18∶82). Detection wavelength was at 203nm, the flow rate was 1.0 mL?min -1 , the injection volume of sample was 10?L and of reference 8?L. Results: The linear response range from 0.432 ～3.456?g of Re(r=0.9992, n=5), 0.360～2.88?g of Rg1(r=0.9998, n=5), respectively. The recovery of Re: 97.0%, RSD=1.4%, the recovery of Rg1: 96.8%, RSD:=1.1%, respectively. Conclusion: The method was proved to be simple, rapid, accurate and reproducible, and suitable for content determination of the oral liquor.

Objective To analyse the distribution characteristics of negative pattern of hepatitis B virus Markers (HBV‐M ) in healthy population in Hangzhou district in 2014 ,and provide strategy for the prevention and control of HBV infection in HBV‐M negative population .Methods The HBV‐M (HBsAg ,HBsAb ,HBeAg ,HBeAb and HBcAb) in blood specimens of health examina‐tion population were tested by using ELISA .For 300 cases preserved HBV‐M negative specimens ,HBsAg and HBsAb were detec‐ted by using chemiluminescence immunoassay and HBV‐DNA was detected by using PROCLEIX ULTRIO? Assay .The viral load of HBV‐DNA reactive sample was quantitatively determined .Results Among 9 143 blood samples ,2 213 samples were HBV‐M negative ,and the negative rate was 24 .20% .The negative rate of male to female was 1∶1 .21 .Using chemiluminescence immunoas‐says and PROCLEIX ULTRIO? Assay simultaneously ,we found one case of low concentration of HBsAg(both HBsAb and HBV DNA nonreactive) ,four cases of low concentration of HBsAb(both HBsAg and HBV DNA nonreactive) ,two cases of HBV‐DNA reactive(HBV‐M negative) .One HBV‐DNA reactive sample could be quantified as 560 IU/mL .Conclusion In HBV‐M (ELISA) negative population of health examination of Hangzhou district ,a few subjects had low concentrations of HBsAg or HBsAb or HBV‐DNA .For HBV‐M negative population ,quantitative detection of HBV‐M and HBV‐DNA before HBV vaccination is recom‐mended to determine w hether they need HBV vaccine and the HBV vaccination plan .

ObjectiveTo develop the manipulation and scoring system of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) into a Chinese software.MethodsThe manual manipulation and scoring system of LOTCA was developed into a technological procedure and changed into primary product of software through conforming computer programs such as Basic, C, C++ and Flash Maker. The primary product was tested in clinic and feedback suggestions were collected. The questions found during assessment and items with reliability and validity not satisfied were optimized.ResultsThe Chinese software of LOTCA, including mandarin and Cantonese, composed manipulation system, scoring system, administer system and affiliated system. It could run on systems of Windows 2000 and Windows XP.ConclusionThe Chinese software of LOTCA is objective, standard and convenient for clinic.

In order to identify host factors which interact with the movement protein (MP) of Apple chlorotic leaf spot virus (ACLSV), ACLSV MP was cloned into the bait vector pGBKT7 and used to screen a cDNA library of Malus sylvestris cv. R12740-7A, which had previously been constructed by yeast two-hybrid sequencing transformation. The protein functions of the identified host factors were determined according to their gene annotations in GenBank. The result showed that the bait plasmid pGBKT7-MP showed no virulence or self-activating effect on yeast strain Y2H Gold. Sixty-nine interactor proteins were identified, which were divided into the following 10 classes according to their described functions: hydrolases; pathogenesis-related proteins; DNA binding proteins; phosphatases; ligases; proteins with catalytic activity; phenylalanine ammonialyases; peroxidases; NAD binding proteins; and proteins of unknown function. Bioinformatic analysis of gene homology suggested that phosphatases, pathogenesis-related proteins and glyceraldehyde-3-phosphate dehydrogenase A may play an important role in the interaction between virus and host. This study may provide a theoretical basis for the further study of viral pathogenesis and virus-host interaction mechanisms.
