Objective To study the clinical features of complicated upper urinary tract infection in children,aiming to provide a reference for clinical diagnosis and treatment of the disease.Methods The clinical data of 68 cases with complicated upper urinary tract infection hospitalized at the Department of Urinary Surgery NO.1,Children's Hospital of Shenzhen between January 2013 and August 2015 were retrospectively analyzed.Results A total of 68 cases,in which 44 were male,24 were female,and repeated infections were found in 15 cases.Fever was the most common clinical manifestation(48 cases,70.59％),while frequent urination and odynuria were rare(9 cases,13.24％).A total of 57 strains had been cultured form the submitted specimens which were obtained from the 68 cases,including 41 strains of gram-negative bacteria,15 strains of gram-positive bacteria and 1 strain of fungus.Two different strains were cultured in 3 children.Fourteen strains of Escherichia coli had 11 extended spectrum beta lactamases (ESBLs)-positive strains.In the 11 strains of klebsiella pneumoniae,8 trains were ESBLs-positive.The drug resistant rates of gram-negative bacteria to Ampicillin and Cefuroxime sodium were both more than 90％.The sensitive rates to Piperacillin/Tazobactam was more than 90％.Thirty-one cases of complicated upper urinary tract infection were cured by administering Piperacillin/Tazobactam,while 15 cases were cured by changing Cefuroxime sodium to Piperacillin/Tazobactam according to the drug sensitivity results.Conclusions Clinical manifestations of complicated upper urinary tract infection are untypical,and fever is the most common symptom.Repeated infection is common.The gram-negative bacteria is the dominant pathogen causing the complicated upper urinary tract infection.ESBLs-positive bacteria accounts for high proportion.The drug resistance rate to penicillin and the first,second generation of the cephalosporin is high.The drug sensitive rate of piperacillin tazobactam is high,with good prognosis.

Objective To investigate the adjunctive therapeutic effects and safety of intravenous immunoglobin (IVIG) for treating pneumonia following kidney transplantation.Methods Sixteen cases of pulmonary infection after kidney transplantation were divided into two groups.Twenty-eight cases were subjected to IVIG therapy (0.2 g·kg-1 ·day-1) for 7-10 days besides the standard specific anti-bacterial,anti-fungal,and anti-virus treatment and regular immunosuppressive regimen with dose adjustment (IVIG group),and the control group was only treated with standard specific anti-pathogen therapy.The incidence and mortality ofsevere pulmonary infection,levels of serum IgG,T lymphocyte subsets,and creatinine in the two groups were observed.Results The effective power of IVIG group and control group was 100 ％ and 93.75 ％ (P＜0.05).The incidence of severe pneumonia in IVIG and control groups was 0 and 12.5％,respectively (P＜0.05),with the mortality being 0 and 6.25％,respectively (P＜ 0.05).The levels of serum IgG were significantly increased in IVIG group as compared with that before treatment and in control group.There were no significant adverse reactions associated with IVIG infusion.Conclusion As an adjunctive therapy,IVIG treatment for pulmonary infection can reduce the incidence of severe pulmonary infection and mortality after kidney transplantation,further increase the survival rate of patients after kidney transplantation.

Objective To explore the current state-trait anxiety among nurses in children's hospital and supply some scientific references for the decision-making to healthy guidance and occupation behavior for the practioners. Methods Investigations were carried out in 410 female nurses in Guangzhou children's hospital by usage of the state-trate anxiety inventory(STAI).The results were analyzed statistically. Results The STAI of nurses in the children's hospital was higher than that of the norreal control (P ＜ 0.01 ).But no difference existed in the aspect of special anxiety (P ＞ 0.05) between them.The special anxiety of female cadre and technical staff was higher than the nurses in the children's hospital (P ＜ 0.01). Conclusion The high level of state-trait anxiety hinted us that we should pay attention to the anxiety status of nurses in the children's hospitals.

Objective To learn the current in vitro antimicrobial susceptibility of Mycoplasma pneu-moniae in Shanghai and to understand the mechanisms of resistance to macrolides. Methods M. pneumoniae was isolated from pediatric patients with low respiratory tract infections(RTI) using broth and PPLO agar medi-um. PCR amplification and sequence analysis of P1 adhesion gene were performed to identify all M. pneumoniae strains. Susceptibility testing was carried out for macrolides, tetracyclines and fluoroquinolones using broth mi-crodilution method with SP4 broth. PCR amplification and sequence analysis of 23S rRNA genes were performed for all M. pneumoniae strains. P1 gene PCR-RFLP typing was performed to subtype the M. pneumoniae strains. Results One hundred and two M. pneumoniae strains were isolated in Shanghai from Oct 2005 to Dec 2008. All M. pneumoniae isolates were susceptible to the tetracyclines and fluoroquinolones tested. Of 102 clinical isolates, 83(81.4%) was resistant to erytbromycin and all 83 erythromycin-resistant strains had MIC>128 mg/L. An increasing trend of resistance rates were showed: 16.7% (1/6) in 2005, 76.5% (13/17) in 2006, 100.0% (24/24) in 2007 and 81.8% (45/55) in 2008. All macrolide-resistant M. pneumoniae strains harbored an A2063G transition mutation in domain V of 23S rRNA genes. The P1 gene RFLP type 1 is predominant (85.3%, 87/102) in M. pneumoniae clinical isolates. Conclusion The macrolide resistance rate of M. pneu-moniae is very high in Shanghai. The mechanism of macrolide resistance is associated with transition mutation on the 23S rRNA gene.
