Objective:To develop and study the properties of ion-exchange polyvinyl alcohol-acrylic acid microspheres(PVA-AA-Ms) for embolization.Methods:The PVA-AA-Ms were produced by the method of inverse suspension polymerization.The morphology and particle size were determined by optical microscope;FT-IR was used to investigate the special functional groups of PVA-AA-Ms;the carboxyl content of PVA-AA-Ms was measured by chemical titration;the compression elasticity was examined by texture analyzer(TA-plus).Pingyangmycin(bleomycin A5) was used as model drug to prepare drug-loaded PVA-AA-Ms.Drug loading and entrapment efficiency were measured through UV-spectrophotometer;in vitro drug release characteristic was detected by constant temperature vibration dialysis assay.Results:The PVA-AA-Ms were round and integrated.The average diameter of PVA-AA-Ms was 500 ?m with a range of 150-1 000 ?m.The carboxyl vibration was demonstrated by FT-IR and the content of carboxyl was 8.905 mmol/g.PVA-AA-Ms were mechanically stable with appropriate elasticity.Drug loading and entrapment efficiency were 30 g/L and 99.4%,respectively.The drug release rate was slow in phosphate buffer solution(PBS),88.3% of the drug was released after 24 h and the t50 was 2.19 h.Conclusion:PVA-AA-Ms prepared in this study were supposed to be suitable for clinical embolization according to the physicochemical properties.The high carboxyl content of PVA-AA-Ms which allowed them to load cationic drugs(e.g.,drug with amino group) through ion-exchange mechanism brought broad prospects for combination of embolization and chemotherapy.

Objective To study on the drug-resistance mechanism of Brucella resistance to Quinolone antibiotics to guide the selection and use of antimicrobial agents in clinical practice. Methods Six strains of Brucella melitensis(Bru1, Bru2, Bru3, Bru4, Bru5, Bru6) were selected to be induced resistance to levofloxacin in vitro respectively. The MICs of the 6 strains of Brucella melitensis and induced resistant strains were measured by agar dilution method. The sensitivity to Quinolone antibiotics (Levofloxacin, Ciprofloxacin, Lomefloxacin, Norfloxacin, Fleroxacin, Ofloxaein) of 6 strains of Brucella melitensis and induced resistant strains was measured by K-B method. The gyrA of the 6 strains of Brucella melitensis and induced resistant strains was amplified by PCR, then the nucleotide sequence of the genes were analyzed. Results The MICs of Bru1,Bru2,Bru3,Bru4, Bru6 were 0.50 μg/ml and Bru5 was 0.25 μg/ml. The strains Bin3, Bru4 were induced into drug-resistant strains by Levofloxacin, then were named LEVR3 and LEVR4 respectively. The MICs of LEVR3 and LEVR4 were 64,128 μg/ml with 128 and 256 times higher than that of the parental strains. The 6 strains of Brucella melitensis were sensitive to Quinolone antibiotics, LEVR3 and LEVR4 were resistant to Quinolone antibiotics. Neucleotide sequence analysis and comparison of the derived amino acid sequence revealed that Quinolone resistance-determing region of GyrA had a substitution at position Ala87 and Asp91 in laboratory resistant strains. Conclusion The results of in vitro experiments show that acquired resistance of Brucella melitensis strains to Levofloxacin could beinduced when exposed to high level of some antibacterial agents for short term. Two drug-resistant strains occur mutations in gyrA and have cross-resistance to other Quinolones.

Objective:To develop lipiodol-containing calcium alginate microspheres (LAMs) for embolization,and study the characterization for emoblization and the radiopacity. Methods:LAMs were prepared by dripping method. The preparation of LAMs was optimized by orthogonal experiment which involved effects of three factors (the volume ratio of lipiodol to the external aqueous solution,airflow rate,and the weight pushing the injector) at three levels on the responses to the size,polydisperse index and entrapment efficiency of LAMs. The morphology of LAMs was observed under microscope. The elasticity of LAMs was investigated by texture analyzer. The capability injected through catheter of LAMs was monitored by video spinning-drop tensionmeter. The radiopacity of LAMs was measured by X-ray imaging system after LAMs were injected into vas of a rat. Results:The optimal condition for preparation of LAMs was:the volume ratio of lipiodol to the external aqueous solution was 3∶ 10,airflow rate was 40 g/mL and the weight pushing the injector was 100 g. According to the optimized condition,LAMs were prepared and characterized. The mean diameter of LAMs was (493.9?42.6) ?m,the polydisperse index was 1.02 and the entrapment efficiency was (88.97?1.09)%. The LAMs were with round shape and smooth surface in view of photograph of microscope. The maximum average load was (1.09?0.18) N when LAMs were compressed to 60%. The LAMs were injected through catheter without much difficulty. The radiopacity of LAMs in rats was demonstrated to be visible under X-ray photography system. Conclusion:The radiopaque LAMs developed are suitable for the arterial embolization,with round shape,proper size,good elasticity,easy handling character and visible property under X-ray imaging. The radiopaque embolic agent is supposed to be useful for emoblization therapy.
