BACKGROUND:Machinable bioglass-ceramics became a new inorganic biomaterial; moreover, strength, toughness and machinability are significantly studied.OBJECTIVE: To observe the effect of ZnO, Fe2O3 and ZrO2 additives on the microstructure and properties of machinable bioglass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system.DESIGN: Observational contrast study.SETTING: Department of Orthopaedics, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Laboratory of Materials, Wuhan University of Technology from October 2003 to April 2004. K2O-MgO-CaO-SiO2-P2Os-F system, ZnO, Fe2O3 and ZrO2 additives, D/Max-ⅢA X-ray diffractometer (Japan), JSM-5610LV scanning electron microscope (SEM), HVS-1000 microhardnessmeter and 3257-35 magnetic testing device (Japan) were used in this study.METHODS: In the glass-ceramic of K2O-MgO-CaO-SiO2-P2O5-F system, three kinds of additives ZnO, ZnO-Fe2O3 and ZnO-Fe2O3-ZrO2 were added respectively. These three kinds of ceramics were prepared by being melted at 1 400 ℃ for 1 hour. After fire, crystal temperature was set based on differential thermal analysis curve. ① Physical properties: Microhardness was determined with microhardnessmeter (HVS-1000). The flexural strength and fracture toughness were established measured with ceramic mechanical test system (MTS) method and single edge notched beam (SENB) method, respectively. Saturation magnetic moment and Curie temperature were determined with 3257-35 magnetism test machine made in Japan. Holing method was used to measure machinability. ② Test of crystalline phase and microstructure: Crystalline phase analysis was carried out with X-ray diffraction (XRD: D/Max-ⅢA) and microstructure analysis were conducted on an etched fracture surface using SEM (JSM-5610LV,Japan). MAIN OUTCOME MEASURES: Effects of ZnO, Fe2O3 and ZrO2 additives on physical properties, mineral composition and crystalline phase.RESULTS: ① The addition of ZnO to the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system was beneficial to crystal growth, increasing aspect ratio of crystal, decreasing microhardness and improving toughness and machinability. ② The addition of ZnO-Fe2O3 to the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system can form minority Mg-Zn ferrite with magnetism. The main crystalline phase present in the glass- ceramic was diopside with small size and hardness was improved, which led to worse machinability. ③ Because of the addition of ZnO-Fe2O3-ZrO2, magnesia fluormica and fluorapatite became the main crystalline phases, and the minor phases including Mg-Zn ferrite, t-ZrO2 and m-ZrO2, etc.also presented in the glass-ceramic. This material possessed high strength and toughness, good machinability and magnetism, which could stimulate formation of new bone, and was good substitute of bone restorations. Bioassay and in vitro test indicated that the glass-ceramic in K2O-MgO-CaO-SiO2-P2O5-F system was bioactive and biocompatible. CONCLUSION: ZnO, Fe2O3 and ZrO2 additives play a significant role in changing crystalline structure, enhancing strength,toughness and machinability of machinable bioglass-ceramic and generating magnetism.

Objective To investigate the relationship between antibiotic use and antimicrobial resistance in Acinetobacter bau-mannii for rational use of antibiotics.Methods Antibiotic use density (AUD)of common antibiotics in hospitalized patients were collected in a tertiary hospital between 2006 and 2010.Clinical isolates of A.baumannii from those patients were collect-ed.The resistance to common antimicrobial agents were tested by disk diffusion method according to Clinical and Laboratory Standards Institute (CLSI,2012)guidelines.Relationship between antibiotic use and antimicrobial resistance in A.baumannii was analysed by SPSS 16.0.Results The resistant rates of A.baumannii isolated from inpatients were high.Consumption of cephalosporins and quinolones were large.There was a positive correlation between the resistant rate of A.baumannii to imi-penem and AUD of carbapenems (r=0.975,P <0.05).The resistant rate of A.baumannii to meropenem showed significantly positive relation to AUD of carbapenems (r= 0.975,P <0.05).Resistant rates of aminoglycosides,quinolones,cephalospo-rins and beta-lactamase inhibitors was not correlated to AUD of those antibiotics.Conclusions We should pay more attention to the high prevalence of resistant A.baumannnii strains.Application of imipenem and meropenem should be strictly controlled.Amikacin and beta-lactamase inhibitors are better choice for empirical antibiotic therapy in the treatment of infections caused by A. baumannii.

OBJECTIVE:To provide reference for improving the charge system of drug registration in China so as to promote work efficiency and quality of drug registration. METHODS:Through comparing the implementation of drug registration and evaluation in Japan and China(registration institution,process,cycle,etc.),Japanese charge standard of drug registration system was evaluated and its characteristics were analyzed,so as to put forward the suggestion for charge standard reform of drug registration in China. RESULTS & CONCLUSIONS:Japanese drug registration was internal review, with the independent administrative institution Pharmaceuticals and Medical Devices Agency(PMDA)as main body,combined with the opinions of the external experts;there was a strict control standard for the registration cycle. Specific fee was confirmed by the charge standard according to new drug registration,drug re-registration,first application,extension application,first or second category of drugs, orphan drugs or non-orphan drugs. Japanese charge standard was characterized with clear classification of charge standard,high fees, close relationship of charge level with drug types. The procedures for drug registration were more cumbersome in China,and involved more relevant institutions and personnel at different levels;there was not strict restriction on registration period;relatively rough charge standard,low fee and not detailed charge classification also existed. It is suggested to draw lessons from the experience for charge standard formulation and management of drug registration in Japan,improve the current drug registration charge system in China by adding charge standard of drug registration into annual report of Center for Drug Evaluation,raising the amount of fee, subdividing the charge items and setting up the feedback mechanism,which lay a solid foundation for improving the efficiency and quality of drug registration in China.

Pharmaceuticals were chosen as the entry point to analyze the status and characteristics of China′s pharmaceutical exports. An export competitiveness evaluation system was comprehensively constructed by selecting the scale, quality and progress of international trade as three dimensions. Net exports, export contribution rate, international market share, display comparative advantage index, competitive advantage index, Michaely index and export advantage growth index as seven indices. In order to avoid the discrepancy caused by the different angles of each index, the indicators were abstracted into two comprehensive ones through principal component analysis, to measure the export competitiveness of the world′s leading countries and regions in pharmaceuticals import and export directly. The result shows that China′s exporting competitiveness of pharmaceuticals ranks the sixth among the 10 major import and export countries in the world. On this basis, dialectical reference is made from Switzerland with strong export competitiveness of pharmaceutical products, in order to promote the long-term development of the export of pharmaceutical products in China.
