Objective To identify the spectrum of pathogenic microorganisms of urinary tract infection and the drug resistance in a hospital setting. Methods The pathogenic microorganisms isolated from 3117 mid-stream urine samples of patients admitted in Hangzhou First People's Hospital from 2005 to 2007 and their drug resistance results were retrospectively analyzed. Results Bacteria were the most prevalent microorganisms in the urinary tract infection, and followed by fungus, mycoplasma and chlamydia. Escherichia eoli accounted for the largest proportion of gram-negative bacteria, in which the ESBLs positive strains accounted for 51.2%, and their drug resistance rate was much higher than that of ESBLs negative strains. Main gram-positive coccobacteria was all sensitive to vancomycin, and relatively sensitive to nitrofurantnin and ampicillin. Conclusions Escherichia coli continue to prevail upon the spectrum of pathogenic microorganism of the urinary tract infection, and the fungus, mycoplasma and chlamydia infections are rising. Antibacterial agents should be used under the guidance of drug sensitivity test, and the combined use should be avoidd.

Objective To evaluate the clinical efficacy and safety of chemotherapy weekly in the chemoradiotherapy of cervical cancer.Methods Between Jan 2003 and Oct 2007,168 patients with stage Ⅲ B squamous cell carcinoma of the uterine cervix in Chongqing Cancer Hospital were divided into two groups randomly.The observation group,total 86 patients receiving radiotherapy concomitant with weekly cisplatin and taxol;the matched group,total 82 patients,receiving radiotherapy concomitant with cisplatin plus taxol every 3 weeks.There were no statistical difference in the clinical and pathological characteristics between the two groups. We compare the 5 years survival rate and side reaction of the two groups.Results The 5 years survival rate of the observation group and the matched group were respectively 52.3%(45/86)and 42.7%(35/82),in which there was no significant difference (P >0.05).The response rate(CR+PR)were respectively 94.2%(81/86)and 92.7%(76/82)in the observation group and the matched group,in which there was no significant difference (P >0.05).Grade Ⅲ acute gastrointestinal toxicities (nausea and vomi-ting)in the matched group were exactly higher than that in the observation group [19.5%(16/82)vs.8.1% (7/86),P <0.05]. Moreover,Grade Ⅲ myelosuppression in the matched group were exactly higher than that in the observation group [20.7%(17/82) vs.9.3% (8/86),P <0.05].there were no significant difference of the incidence of the radiocystitis,radiation proctitis and radio-dermatitis between the two groups.But the Radiotherapy completion time in the matched group were exactly longer than that in the observation group [(61.12±6.71)days vs.(54.72±4.76)days,P <0.05].Conclusion The toxicity of the observation group was lower than the matched group.Moreover the efficacy of observation group is similar to the matched group.

BACKGROUND:Many foreign studies confirm that recombinant human growth hormone (rhGH) is a safe and effective agent for treatment of idiopathic short stature (iSS), but there are no long-period and systematical researches reported in China.OBJECTIVE: To observe the promoting effect of rhGH on the growth of children with ISS.DESIGN: Case-control observation.SETTING: Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University.PARTICIPANTS: Ninety-eight children with ISS who were treated in the Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University during December 2004 to March 2006 were involved in this study.Informed consents were obtained from the guardians of these children with ISS. According to the etiological factors, the children were assigned into 2 groups: ISS group (n =30) and growth hormone deficiency (GHD) group (n =68).METHODS : The children in ISS group and GHD group received subcutaneous administration of home-made rhGH (Jinsai Pharmaceutical Co.,Ltd., Changchun at 0.15 IU/(kg ·d) and 0.1 IU/(kg ·d) respectively before sleeping within 6 months.The body height, body mass and bone age were measured before, 3 and 6 months after treatment. The local region of injection was observed and the growth rate was calculated. Bone age was calculated by graphic atlas method and body height was predicated by BP method.MAIN OUTCOME MEASURES: Body height, body mass, bone age and growth rate of children in two groups before, 3 and 6 months after treatment.RESULTS: All the 98 children wereinvolved in the result analysis, without deletion. ①Intragroup comparison: The body height, growth rate of children in two groups 3 and 6 months after treatment were significantly superior to those before treatment [ISS group: body height:(126.5±9.4), (129.1±8.6), (121.1 ±11.0) cm (P ＜ 0.01), growth rate: (7.3±2.9), (7.5±2.7),(3.5±2.1) cm/year (P＜ 0.01); GHD group: body height: (111.0±13.0),(114.0±13.0),(108.0±12.0) cm(P＜ 0.01),growth rate: (13.2±3.5), (13.5±3.6), (4.0±2.9) cm/year(P ＜ 0.01)]. Six months after treatment, body height was increased in 27 of 30 children in ISS groups, and in all the 68 children in GHD group. ② Intergroup comparison: The growth rate of children in GHD group was concurrently higher than that in ISS group 3 and 6 months after treatment. ③Adverse reaction and side effect: During the treatment, hypothyroidism was observed in 2 children within 1 to 3 months of treatment,but there was no influence on growth rate after oral administration of thyroxin tablets. Local red swelling of skin was observed in another patient, which stopped automatically after one week duration, but the injection continued.CONCLUSION: Home-made rhGH is a safe and effective reagent for treatment of ISS. It can obviously enhance the body height and growth rate of children. Whereas the inhomogeneity of treatment effect does exist, what's more, therapeutic effect in ISS children is inferior to that in GHD children.
