Objective To explore the risk factors, pathogenic bacteria, drug resistance and corresponding measures of prevention and treatment on lower respiratory tract infection caused by extended-spectrum beta-lactamase-producing bacteria (ESBLPB) in neonates. Methods The patieats were from the neonatal intensive care unit(NICU) of The First People's Hospital of Zhaoqing from Jan. 1998 to Apr. 2001. The secretions of the lower respiratory tract were collected, and bacterial culture and antimicrobial susceptibility testing were done. Results There were 23 positive cases in the 42 cultured cases, and 12 cases out of 23 cases were ESBLPB positive. The positive rate of ESBLPB was 52%(12/23). Of them, 9 cases (75%) had the history of using the third generation cephalosporins, 10(83%) were under mechanical ventilations, 8(67%) were lowbirth weight infants and/or premature infants. There were 21 strains in 12 cases. They were 8(38%)Klebsiella pneumoniae, 5(24%)Enterobacter cloacae, 3(14%) Escherichia coli, 3(14%) Pseudomonas aeruginosa, 1(5%)Stenotrophomonas maltophilia, 1(5%) brevi-flavobacterium strains. The ESBLPBs were sensitive to imipenem, ciprofloxacin, amikacin, levofloxacin, ticarcillin-clavulanic acid, meropenem, piperacillin but resistant to other antibiotics. Ten out of the 12 cases were fully recovered from their infection. Conclusion There are multiple factors to increase the lower respiratory tract infections caused by ESBLPB in neonates. The effective measures associated with the infection prevention include intensive sterilization and isolation, and timely immunigation.

Objective: To determine the content of paeoniflorin extracted from Shaogan Granules by D 101 macro resin. Methods: The determination was performed by RP HPLC using C 18 column methanol∶K 2HPO 4∶acetate∶isopropanol (188∶300∶5∶4) as mobile phase, the column temperature at 30 ?C and wavelenthgh at 230nm. Results: The average recovery was 99.4%. RSD was 1.0%. Conclusion: This method is accurate and highly reproducible. It can be a method for quality control of Shaogan granules.

OBJECTIVE To study the effect of the intervention of monitoring-training-planning(MTP) on use of antibacterials and injections for pediatric acute upper respiratory infection.METHODS In accordance with selected drug use indicators(SDUIS),the pediatric outpatient prescription of acute upper respiratory infection was selected in our hospital from Jun to Aug 2006 as the baseline,and intervented by MTP,then the investigation of post-interfervention was carried out after a month,and then re-intervention research was made,so the cycle continued.RESULTS The percentage ratio of antibacterials,and injection usage,and the average drug fee in pediatric outpatient prescription for acute upper respiratory infection in our hospital was decreased from 75.00%,61.67%,40.33% and 54.29 yuan to 7.00%,5.00%,3.00% and 39.16 yuan,respectively after four rounds of MTP(all P

Objective To study the effect of the intervention mode of MTP on use of antibacterials in upper respiratory infection.Methods Adopt retrospective method to select randomly prescriptions of upper respiratory infection from July to September in 2006 for baseline investigation in Outpatient Clinic of Respiratory Department of the First People's Hospital of the city of Zhuhai in Guangdong province.Then aim physicians was interfered by MTP and investigation of post-interference was carried out after a month.The process of intervention and investigation was carried out repeatedly until June in 2007.The ratio of antibacterials use,injection use percentage and average drug fee was observed in pre/post-interference.Results The ratio of antibacterials use in upper respiratory infection in our hospital was decreased from 81.33% to 0,and the ratio percentage of injection use and average drug fee decreased by 81.69% and 35.47% respectively after four MTP circulations.Conclusion The intervention mode of MTP is feasible and effective on promoting the rational use of antibacterials on upper respiratory infection in Outpatient Clinic of Respiratory Department of our hospital.
