OBJECTIVE To analyze the pathogenic distribution and antimicrobial resistance in respiratory ward and provide the rational information to use antibiotics reasonably. METHODS All pathogens isolated from patients in a respiratory ward from 2005 to 2007 and drug susceptibility results were retrospectively analyzed. RESULTS Totally 264 strains of pathogenic bacteria were isolated,in which 68 strains of Gram-positive bacteria,165 strains of Gram-negative bacteria and 31 strains of fungi.MRSA prevalence was 77.1% and showed a trend of increase.No vancomycin-resistant Staphylococcus aureus or Enterococcus was detected.The resistance rate of Streptoccocus pneumoniae to penicillin,erythromycin and levofloxacin was 44.4-66.7%.Enterobacter and Acinetobacter baumannii showed stable susceptibility to imipenem.Pseudomonas aeruginosa strains were relatively susceptible to cefoperazone /sulbactam,amikacin,gentamicin,piperacillin/tazobactam,ceftazidine,cefepime,cefoperazone and imipenem. CONCLUSIONS The changes in pathogens and antibiotic resistance in the respiratory ward are consistent with the surveillance data in this country,Gram-negative bacteria are still the most common pathogens and the serious degree of bacterial drug resistance is increasing.Our data are useful for the guidance of rational use of antibiotics.

To study the safety and feasibility of Mifepristone combined with Misoprostol terminating early pregnancy after cesarean section, mifepristone combined with misoprostol was used to terminate early pregnancy in 188 women requesting medical abortion. Among them, 27 cases were uterine cicatrix. The results showed that the complete abortion rate in 188 cases was 91.48 % after administration, that in 27 cases of unterine cicatrix was 100 % and that in 161 cases of no uterine cicatrix was 90. 06 % (P＞0. 05). There were no differences in the duration of vaginal bleeding and time from the Misoprostol intake to the expulsion of gestational sac and chorionic villi between the two groups (P＞0. 05). It was suggested that combined administration of Mifepristone and Misoprostol to terminate early pregancy is safe and effective after cesarean section.
