OBJECTIVE To investigate the distribution and drug resistance of pathogens in urinary system infection.METHODS Collected from patients urine specimens of our hospital during Jan 2004 Dec 2008 were cultured,detected and studied drug resistance.RESULTS Among these pathogens,Escherichia coli rated the top one(44%),followed by coagulase negative Staphylococcus,fungi,Enterococcus,Klebsiella pneumoniae,Proteus and Pseudomonas aeruginosa.The Enterobacteriaceae were sensitive to imipenem(100%) and the Enterococcues and Staphytlococcus were sensitive to vancomycin(100%).But they all showed higher drug resistance to other antibiotics.CONCLUSIONS E.coli from urinary tract infection is the most common pathogen.In the treatment of urinary tract infection the commonly used drugs such as gentamicin,ciprofloxacin,etc,have produced a higher resistance.Clinician should pay attention to the changes in their drug resistance and use correctly.

ObjectiveTo compare the influence of laparoscopic and abdominal hysterectomy on cellular immune function. Methods There were 28 patientsreceived laparoscopic hysterectomy (laparoscopic group) and 28 patients treated with abdominal hysterectomy (abdominal group).The surgical effects and the changes of preoperative and postoperative T lymphocyte subsets of two groups were compared.ResultsThe intraoperative blood loss,anal exhaust time,hospital stay and postoperative morbidity of the laparoscopic group were significantly better than those of the laparotomy group[ (84.7 ± 21.7) ml vs.( 108.0 ± 23.8) ml,(19.3 ±4.1) h vs.(23.8 ±3.8) h,(5.12 ± 1.14) d vs.(7.81 ±2.27) d,7.1％ (2/28) vs.17.9％(5/28),P ＜ 0.05 ].CD4 and CD8 in the 1st day after operation of two groups were significantly lower than that before surgery respectively [ laparoscopic group:(38.41 ± 5.52)％ vs.( 40.72 ± 6.46)％,(24.41 ± 3.78 )％ vs.(26.33 ± 4.17)％ ;abdominal group:(38.41 ± 4.97)％ vs.(40.13 ± 6.12)％,(24.41 ±6.32)％ vs.(26.25 ±4.56)％,P ＜ 0.05 ]; but CD4 and CD8 in the 3rd day after operation in the laparoscopic group[ (40.15 ±6.29)％,(27.23 ± 5.12)％] almost returned to normal level before surgery,while CD4 and CD8 in the 3rd day after operation in the abdominal group [ (36.15 ± 5.12)％,(23.15 ± 4.87 )％] still had significant differences compared with that before surgery(P ＜ 0.05).ConclusionsLaparoscopic hysterectomy with less blood loss,rapid postoperative recovery,fewer complications and less impact on cellular immune function,is superior to abdominal hysterectomy.Therefore,it deserves promotion and wide application.

Objective To evaluate the effects of milrinone on plasma levels of C reactive protein (CRP) , TNF-?, IL-8 and IL-10 during and after operation for tetralogy of Fallot performed under cardiopulmonary bypass (CPU) in children.Methods Sixteen ASA Ⅲ-Ⅳ pediatric patients aged l-12yr scheduled for operation for tetralogy of Fallot under CPB were randomly divided into two groups : (1) milrinone group ( M, n = 8) and (2) control group (C, n = 8) . In group M a loading dose of milrinone 50 ?g?kg-1 was given i.v. within 10 min, immediately after aortic unclamping, followed by continuous infusion at 0.2?g?kg ?min-1 . In group C equal volume of lactated Ringer's solution was infused instead of milrinone. Blood samples were taken from the CVP line before anesthesia (T0), 5 min after release of aortic cross-clamp (T1), 5 min after discontinuation of CPB (T2) , at the end of surgery (T3) and 24 h and 48h after operation (T4,5) for determination of plasma levels of CRP, TNF-?, IL-8 and IL-10 by radioimmunoassay.Results There was no significant change in plasma TNF-a concentration in both groups. Plasma CRP level increased significantly at 24 and 48 h after operation (T4 , T5 ) , in both groups and was significantly higher in group M than that in group C. Plasma IL-8 level increased significantly only at T2 and T3 compared to pre-anesthesia value (T0) in group M while in group C it increased significantly from T1-5 (P
