ObjectiveTo investigate the related factors of the occurrence of nosocomial infection and nursing management in operating room for general surgery patients,and provide a scientific basis to reduce the incidence of nosocomial infection of the operating room. Methods304 patients with nosocomial infection from August 2009 to August 2010 in our hospital for surgery were set as the control group.151 cases from September 2010 to October 2011 were named as the intervention group.All cases were analyzed retrospectively.The nursing factors which might affect nosocomial infection in operation room were analyzed by univariate and multivariate logistic regression analysis. ResultsBy univariate analysis,eight operation room nursing factors related to nosocomial infection were screened out:the type of incision,operation time,the following surgery or not,into ICU time,preoperative use of antibiotics,visitors of operations or not,invasive operation.5 highly correlated factors were screened out by multi-factor logistic regression analysis:admission to the ICU time,incision type,operation time,preoperative use of antibiotics,then following surgery.The infection rate and prolapse rate of the control group were significantly higher than those of the intervention group. ConclusionsIn nursing work of the operation room,we can take a series of nursing management interventions to reduce the incidence of nosocomial infection of general surgery.

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.

Objective To investigate the trend of the national Kaschin-Beck disease condition, and provide the scientific basis for the government to make preventing strategy. Methods The data were collected from national surveillance on Kaschin-Beck disease(KBD) condition from 2000 to 2007 by restrospective method. The national X-ray detective rates and KBD condition in the eastern and western areas of China were analyzed. Results Monitoring data were collected from 189 monitoring points in 14 provinces of China, and 21 287 X-ray films were photographed of right hands of children from 2000 to 2007. X-ray detective rate was decreased significantly of national KBD from 2000 to 2007. The condition in the west of China is slightly more serious than the eastern areas, but the average of X-ray detective rate was also decreased from 21.75% to 7.30%. National condition is basically controlled. X-ray detective rate had been controlled below 5%, exept for Qinghai, Tibet and Inner Mongolia and so on. Conclusions Ninty percent of the wards have reached the controlled level according to the X diagnosis standard. In terms of the severity of the disease, most of the wards are occupied by patients with slight condition, 10% ward with moderate condition, less than 1% ward with serious condition.

OBJECTIVE:To clone,prokaryotic express and characterize the TEM-type ?-lactamase produced by Enterobacter cloacae clinical isolate EC002. METHODS: The drug susceptibility of Enterobacter cloacae clinical isolate EC002 was detected by agar double dilution,double disk screening and confirmatory test were employed to detect the ESBLs. The isoelectric point (pI) of enzyme was detected by isoelectric focusing electrophoresis (IEF),the genes were coded by PCR amplification enzyme,and the prokaryotic expression and phenotype of the TEM-type ?-lactamase were detected. RESULTS: Enterobacter cloacae EC002 were resistant to most of the ?-lactamases. Positive results were noted for the phenotype identification and plasmid conjugation test. IEF showed that Enterobacter cloacae EC002 produced two ?-lactamases with pI value at 8.7 and 5.4 respectively,which were confirmed to be CTX-M-22 and a new TEM-subtype ?-lactamase by DNA sequencing,and the phenotype of the expressed enzyme of the cloned strains was non-ESBLs. The TEM-type ?-lactamase was named as TEM-141 by GenBank. CONCLUSION: The TEM-141 produced by Enterobacter cloacae EC002 was a new type of plasmid-mediated broad-spectrum ?-lactamase.
