铜陵市部分医院细菌耐药性监测与分析

Objective To investigate the bacterial resistance of clinical isolates collected in Tongling area.Methods The clinical isolates were collected in Tongling area from Jananuary to December in 2007.Antimicrobial susceptibility test were conducted by Kirby-Bauer method.Results Of 1375 clinical isolates,399 strains(29.0%)were gram positive bacteria,and 976 strains(71.0%)were gram negative bacteria.Methicillin resistant staphylococcus aureus(MRSA)accounted for 18.4% of staphylococcus aureus,while methicillin resistant coagulase negative staphylococci(MRCNS)were 70.0% of coagulase negative staphylococci(CNS)respectively.MRSA and MRCNS were highly resistant to gentamicin,ciprofloxacin,clindamycin and erythromycin;but displayed lower resistance to rifampicin,chloramphenicol and nitrofurantion.No vancomycin-resistant staphylococcus strain was found.The resistance rates of Enterococcus faecalis were relatively low to penicillin,ampicillin,nitro furantion,fosfomycin and chloramphenicol.No vancomycin or teicoplanin-resistant enterococcus faecalis was isolated.The resistance rates of E.faecium were lower to fosfomycin and chloramphenicol.Two strains of vancomycin-resistant E.faecium were identified.About of 49.3% of E.coli and 35.9% of Klebsiella isolates produced extended-spectrum β-lactamases(ESBLs).The resistance rates of ESBLs-producing strains to 20 antimicrobial agents were much higher than those of ESBLs nonproducing ones.No imipenem or meropenem-resistant isolate was found.The resistance rate of non-fermenters was lower to imipenem,meropenem,cefoperazone-sulbactam,piperacillin-tazobactam,ceftazidime,cefepime,amikacin or ciprofloxacin.Conclusion The resistance rate of gram positive bacteria is lower to glycopeptides.The resistance rate of gram negative bacilli is lower to imipenem,meropenem,cefoperazone-sulbactam,and piperacillin-tazobactam.Surveillance of bacterial resistance is of great importance for rational use of antibiotics and reducing the emergence of resistance.     

137例慢性乙型肝炎患者肝功能与乙型肝炎病毒DNA及乙型肝炎e抗原相关性分析

目的探讨慢性乙型肝炎患者治疗过程中血清丙氨酸氨基转移酶（ALT）、天门冬氨酸氨基转移酶（AST）水平变化与乙型肝炎e抗原（HBeAg）和慢性乙型肝炎病毒（HBV）DNA的相关性。方法 137例血清ALT、AST水平正常的慢性乙型肝炎患者中HBeAg和HBV DNA同时阳性46例,同时阴性48例,单项HBVDNA阳性35例,单项HBeAg阳性8例。3～6个月后分别对各组患者复发前后血清HBV DNA、ALT、AST水平及ALT、AST异常水平的例数进行比较。结果复发前HBeAg和HBV DNA同时阳性组、HBV DNA阳性组、HBeAg阳性组的ALT、AST水平分别为（22.93±18.45）U/L和（24.12±15.67）U/L、（21.74±16.48）U/L和（17.87±18.05）U/L、（20.55±17.33）U/L和（19.72±16.91）U/L,复发后分别为（529.65±252.42）U/L和（434.18±218.53）U/L、（419.06±204.26）U/L和（476.63±189.43）U/L、（326.48±187.95）U/L和（347.27±198.15）U/L,差异均有统计学意义（P〈0.05）。HBeAg和HBV DNA同时阴性组ALT、AST水平复发前后差异无统计学意义（P〉0.05）。结论血清HBeAg和HBV DNA的检测对慢性乙型肝炎患者诊断、治疗、预后判断有重要的作用,提示慢性乙型肝炎治疗HBeAg的阴转和HBV DNA不能检出能维持较低的复发率。
