OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens. METHODS Statistical methods were used to analyz the data of pathogens origin and drug resistance from 2005 to 2007. RESULTS A total of 326 strains were isolated from 604 nosocomial infection cases (54.0%),from which the Gram-negative bacilli were predominate (44.1%). The isolation rate ot fungi and Gram-positie bacteria was 41.6% and 14.3%,respectiviely. The top three pathogens were the fungi (41.6%),Pseudomonas aeruginosa14.3%,and enterobacter (10.6%). The rate of ampicillin-resistant Escherichia coli was 100%.The isolation rate of MRSA and MRCNS was up to 100.0% and 80.0%. CONCLUSIONS Fungi is common high among pathogens.The emergence of drug-resistant pathogens will continue to be a serious problem,we must take it intimately.

Objective To evaluate the effect of antimicrobial management guideline on the daily antimicrobial use rate in a general hospital.Methods An one-day point-prevalence survey on antimicrobial use in hospitalized patients was conducted in 2010,2011,and 2012 by means of cross-sectional investigation method.Results The daily utiliza-tion rate of antimicrobial agents in 2010,2011,and 2012 was 65.40% ,42.09% and 26.74% respectively,the rate of the submission of specimens for bacterial culture was 22.53% ,35.74% and 41.74% respectively(χ2 trend= 266.42, 29.02,respectively,bothP<0.01). The utilization rate of single drug was 83.72% ,80.27% and 93.41% respec-tively. the utilization rate of both two-drug and more than three-drug combination kept a downward tendency. The utilization rate of antimicrobial agents in several departments(digestive internal medicine,cardiovascular,hematolog-ical tumor,neurology,general surgery,orthopedics,obstetrics,pediatrics,and ophthalmology)showed a decreasing tendency(all P<0 .0 1 ).Conclusion The implementation of antimicrobial management guideline has remarkably re-duced the daily antimicrobial use rate,and increased etiological detection rate for therapeutic antimicrobial use.

A novel and highly sensitive voltammetric enzyme-linked immunosensor was developed based on tyramine) oxidation deposition. It was shown that gold nano-particles(colloid Au) could be used as a platform to immobilize antibodies by adsorption. By a sandwich immunossary format with goat-anti-human IgG labled Horseradish peroxidase(HRP) as the second antibody and catalytic amplification by biotin-tyramine, the immunosensor′s) catalytic ability to hydrogen peroxide increased nearly 20 times), the sensor exhibitd a linear response to human IgG in the concentration range from 1.5 μg/L-22 mg/L, and the detection limit was 0.1 μg/L), the regression equation could be expressed as Δi_p(μA) =2.8859c(mg/L)+17.152 with a correlation) coefficient of 0.9872. The immunosensor can be used to quantitatively determine hIgG in the sample) of human serum).

It analyzed the definition, mechanism, characteristics of Mirror Visual Feedback and summarized the application of mirror visual feedback in recovering upper limb function after stroke patients at home and abroad, so as to provide evidences for the further research in China.

Objective To analyze the Chengdu municipal social support network of chronic disease elderly to provide refer-ence for systematically building and perfecting the pension system of urban community chronic disease elderly.Methods The self-designed questionnaire and convenience sampling method were adopted to perform the investigation on 234 aged patients with chro-nic disease from Chengdu City.Results The prevalence rates of one,two,three or more chronic diseases were 56.84%,27.78%and 15.38% respectively.The demands for economic,care and spiritual support in the elderly patients with chronic disease were 66.70%,50.00% and 78.20% respectively.The education degree,fixed monthly income,monthly average cost of disease,number and time of suffering from chronic diseases affected the demands for social support.The economic,care and social support degrees were(3.72 ± 1.37),(3.90 ± 1.19)and(3.64 ± 1.08)point respectively.Level of education,marital status,fixed income,duration of illness,and cost of illness affected the social support degree.The economic and care support mainly came from the spouses and chil-dren,but the spiritual support not only came from the inside family,but also the part came from the outside family.Conclusion Constructing a perfect social support network with multiple approaches of community and family is conducive to improve the quality of life in chronic disease elderly.

Objective    To analyze the risk factors for acute kidney injury (AKI) after off-pump coronary artery bypass grafting (OPCABG). Methods     The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang data, CBM, VIP, CNKI were searched by computer for researches on risk factors associated with the development of AKI after OPCABG from the inception to March 2022. The meta-analysis was performed using RevMan 5.4 software. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included studies. Results    A total of 18 researches were included, involving 9 risk factors. The NOS score of all included studies was≥6 points. Meta-analysis results showed that age [OR=1.03, 95%CI (1.01, 1.06), P=0.020], body mass index (BMI) [OR=1.10, 95%CI (1.05, 1.15), P<0.001], history of hypertension [OR=1.45, 95%CI (1.27, 1.66), P<0.001], history of diabetes [OR=1.50, 95%CI (1.33, 1.70), P<0.001], preoperative serum creatinine level [OR=2.05, 95%CI (1.27, 3.32), P=0.003], low left ventricular ejection fraction [OR=4.51, 95%CI (1.39, 14.65), P=0.010], preoperative coronary angiography within a short period of time [OR=2.10, 95%CI (1.52, 2.91), P<0.001], perioperative implantation of intra-aortic balloon pump [OR=3.42, 95%CI (2.26, 5.16),  P<0.001], perioperative blood transfusion [OR=2.00, 95%CI (1.51, 2.65), P<0.001] were risk factors for AKI after OPCABG. Conclusion    Age, BMI, history of hypertension, history of diabetes, preoperative serum creatinine level, low left ventricular ejection fraction, preoperative coronary angiography within a short period of time, perioperative implantation of intra-aortic balloon pump, perioperative blood transfusion are risk factors for AKI after OPCABG. Medical staff should focus on monitoring the above risk factors and early identifying, in order to prevent or delay the onset of postoperative AKI and promote early recovery of patients.
