OBJECTIVE:To provide reference for improving the registration success rate of new drug research and develop-ment(R&D)enterprises after adjusting drug registration system in China. METHODS:The national drug policies,regulations and related documents were comprehensively studied and combed to explore the main contents of drug registration system adjustment and its effects on the R&D forms,drug patent and on-site verification. The suggestions were put forward. RESULTS & CONCLU-SIONS:The adjusted drug management system showed new definitions for new drugs and generic drugs in China,as well as de-tailed requirements and regulations for drug R&D conditions,process and on-site inspection. It enhanced the protection of patents and patentees. The new drugs should be assessed its market value and clinical advantages. Data contents and requirements for drug registration declaration were made the relevant adjustments. New drug R&D enterprises should develop drug listed license manage-ment system as early as possible based on the implementation of listed license management system pilot,improve its efficiency and benefit. The new drug R&D should notice the clinical efficacy and demand of market,focus on the drugs with good clinical effica-cy in common diseases,frequently-occurring diseases and major diseases;and those for treating rare diseases,the elderly and chil-dren disease can use easy access or fast track to accelerate the speed of drug registration. New drug R&D enterprises should im-prove the R&D conditions,and standardize the management of development process to ensure the effective and smooth develop-ment.

OBJECTIVE To investigate the application of antibacterials in patients accepted operation in grass-roots(hospitals),so to standardize the application of antibacterials and cut down the medical cost.METHODS Full-time administrators for nosocomial infection investigated the application of antibacterials in patients who accepted(operation) in Sep 2004,and filled in the questionnaires.RESULTS In 1 383 cases of 11 hospitals the application rate of antibacterials was 98.63%;in which 86.50% were for prophylactic usage and 13.50% for therapeutic usage;(29.90%) for single antibiotics treatment and 50.15% for bigeminy,18.70% were for trigeminy.Time of(application) differentiated(6.90,7.00,6.60d) fromⅠto Ⅲ kinds of operation.Per capita cost of antibacterials was $956.50(47.60%).CONCLUSIONS High cost of antibacterials results from such factors as multiple kinds,long time and(combined) application.

Objective To study the genomic molecular organization and genotype of human astro-virus infected infants in Shanghai of China. Methods Based on the published genomic sequence of HAstV (GenBank), the whole genome of one isolate human astrovirus was sequenced by specific primers. The PCR-products were cloned to pMD18-T vector and sequenced, phylogenetic tree was constructed by the Neighbor-Joining method with MEGA 4 software. Results The genome of HAstV-SH is 6807 hp, contains three ORFs: ORF1a and 1b encode the non-structural protein (from 83 nt to 4372 nt), ORF2 encodes the structural protein (from 4364 nt to 6727 nt). Compared with the ORF2 gene of those eight astrovirus sero-types in GenBank, revealed that the highest homology is with genotype 1 (97%). Homology with other gen-otypes ranged between 63% and 70%. Conclusion HAstV-SH belonged to genotype 1 and closely clus-tered with a strain of Japan (AB009985).

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

Objective To explore the application value of three-dimensional (3D) female pelvic visualization model on transvaginal gynecological ultrasound imaging.Methods The second digital Chinese woman visible human datasets was selected,and a female pelvicvoxel-based model was constructed in Amira software for analog simulation combined with transvaginal gynecological ultrasound.The main structures and the space position variation of female pelvic cavity were observed,and the comparison study with conventional section of ultrasound was carried out.Results A high accuracy 3D visualization model of female pelvic was successfully constructed,and the anatomy structures can be dynamically and clearly displayed in any section orientation.An analog simulation research was carried out according to the scan mode of gynecological ultrasound,and a series of high resolution images consistent with scan sections of dynamic ultrasound were obtained,which had provided the optimal scan pathway for the fast inspection of the uterus,fallopian tubes and ovaries.Conclusion The 3D female pelvic visualization model based on digital Chinese woman human datasets has provided detailed and accurate anatomy information for transvaginal gynecological ultrasound imaging,which could be the benefit for doctors to understand the ultrasound images of female pelvic,as well as the accurate positioning ability to the lesions of female pelvic cavity.

This study aims to investigate the genetic characteristics of hemagglutinin in wild-type measles viruses in Henan Province, China and to provide a basis for measles control and elimination. Specimens were collected from suspected measles cases in Henan during 2008-2012. Cell culture was performed for virus isolation, and RT-PCR was used to amplify hemagglutinin gene. The PCR products were sequenced and analyzed, including construction of phylogenetic tree and analysis of the distance between the isolated virus and the reference virus; then, the variations in predicted amino acids were analyzed. The results showed that 12 measles viruses were isolated in Henan Province and identified as H1a genotype; the nucleotide and amino acid homologies were 98.0%-100% and 97.2%-99.8%, respectively. One glycosylation site changed in all the 12 sequences because of the amino acid mutation from serine to asparagine at the 240th site, as compared with Edmonston-wt. USA/54/A. Overall, the wild-type measles virus genotype circulating in Henan Province from 2008 to 2012 was H1a, with high homology between strains; there were some variations in amino acid sequences, resulting in glycosylation site deletion.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.
