Objective To investigate the multidrug-resistant bacteria infection in pediatrics of our hospital and guide the rational usage of antibiotic,Methods The retrospective survey method was adopted to analyze the multidrug-resistant bacteria infection of 591 patients in paediatrics from 2009 to 2011.Results There were no statistical differences of multidrug resistance bacteria infection rates in the three years (x2 =0.028,P =0.986).Among 591 patients,17 patients were with multidrug-resistant bacteria infection,the positive rate was 2.87％,82.4％ origin of society area,64.7％ was respiratory tract infection,58.8％ resistance bacteria including Klebsiella pneumoniae and Escherichia coli,appear multidrug resistance bacteria infection previous all used antibiotic drugs.Conclusion The multidrug resistance bacteria infection is related to occur in paediatrics abuse and unrationaly use of antibiotics.Its should be strengthened to supervise and manage.

Objective To investigate the risk factors of acute kidney injury following coronary artery bypass graft(CABG).Methods Twenty-six patients suffering from acute kidney injury following CABG as the patient group and 59 individuals without impairment of renal function as the control from January 2008 to September 2012 in the First People's Hospital of Yichang according to a retrospective case-control study and nonconditional multivariable Logistic regression analysis method..Results Among the 85 patients undergoing CABG,26 suffered acute kidney injury following CABG with a morbidity rate of 30.59％.Identified risk factors for acute kidney injury following CABG included pre-operative mederale-sever cardiac insufficiency,prolonged mechanical ventilation,prolonged stay in ICU and anemia before surgery.The identified independent risk factor of acute kidney injury following CABG was pre-operative mederale-sever cardiac insufficiency (OR =3.206,95％ CI:1.067-9.631).Condusion Pre-operative mederale-sever cardiac insufficiency was an independent risk factor of acute kidney injury following CABG.
