Objective To analyze antimicrobial use in the different grades of hospitals within 3 years after the car-rying out of rectification activities of antimicrobial use,and provide basis for making continuous improvement pro-gram of antimicrobial management.Methods Retrospective analysis was performed,outpatient and emergency pre-scriptions and medical records of discharged patients (100 were type Ⅰ incision surgery)were selected from 5 tertia-ry hospitals and 5 secondary hospitals within 3 months,antimicrobial use and management were investigated. Results 200 outpatient prescriptions,100 emergency prescriptions,and 200 medical records of discharged patients were selected from each hospital.In tertiary and secondary hospitals,antimicrobial usage rate in outpatient prescrip-tions was 17.40% and 18.00% respectively,emergency prescriptions was 31 .60% and 40.10% respectively;a-mong inpatients,antimicrobial usage density(AUD)was (28.13±8.04)and (49.67±11 .63)respectively,and anti-microbial usage rate was 41 .30% and 56.20% respectively;pathogenic detection rate of antimicrobial therapeutic cases was 45.70% and 22.70% respectively,therapeutic cases with limit level of antimicrobials was 61 .50% and 27.40% respectively;antimicrobial usage rate in type I incision surgery was 20.00% and 40.40% respectively;The rational rate of antimicrobial types was 94.60% and 59.20% respectively,rational rate of opportunity of antimicro-bial use was 95.20% and 48.20% respectively;combination rate was 8.80% and 36.60% respectively,and rational rate of treatment course was 84.00% and 52.80% respectively.Conclusion In tertiary hospitals,antimicrobial use after 3 years rectification of antimicrobial use conform to the antimicrobial management requirement of Ministry of Health,the overall quality index is better than secondary hospitals,management of antimicrobial in secondary hos-pitals use should be improved.

Objective To understand antimicrobial resistance and homology of carbapenem-resistant Klebsiella pneumoniae (CRKP)from an intensive care unit (ICU).Methods 11 CRKP isolates from patients and environment of an ICU in a hospital were performed antimicrobial susceptibility testing,the homology of CRKP was analyzed by randomly amplified polymorphic DNA (RAPD)method.Results Of 11 CRKP isolates,8 were from patients,and 3 from environment,the main specimen was sputum(n =6,54.55%).Antimicrobial susceptibility testing results re-vealed that 10 (90.91%)CRKP isolates were resistant to ciprofloxacin;11 isolates were susceptible to compound sulfame-thoxazole,intermediate to imipenem,and resistant to other antimicrobial agents(100%).All 11 CRKP isolates had 3 bands,and were divided into two types:(typeⅠ,n=10;type Ⅱ,n=1).Conclusion Antimicrobial resistance of Kleb-siella pneumoniae in ICU is serious,CRKP isolated from ICU patients and environment are of the same clone. Cleaning,disinfection,and monitoring of ICU environment should be strengthened,which is helpful for reducing, timely warning of multidrug-resistant organisms,and reducing healthcare-associated infection.

Objective To explore the status of depression in patients with advanced schistosomiasis and its influencing fac-tors,so as to provide the evidence for improving psychological interventions. Methods A total of 206 patients with advanced schistosomiasis were investigated with the self-designed general information questionnaire,the Self-Rating Depression Scale,and WHOQOL-BREF Form. Results Among the 206 cases,the incidence of depression was 69.4%,and depression was negatively related to the quality of life(P = 0.000). The multiple logistic regression analysis showed that the times of hospitalization(β=0.442,P=0.007)was a risk factor for depression,while the high education levels(β=-0.583,P=0.011)and the history of por-tal hypertension operation(β=-0.917,P=0.000)were the protective factors. Conclusion The incidence of depression in ad-vanced schistosomiasis patients is high,and it is influenced by various factors. Therefore,we should take corresponding interven-tions to reduce its occurrence.

OBJECTIVETo identify clinical characteristics of hospitalized laboratory-confirmed influenza cases of children under 15 years old, and their risk factors of influenza infection.

METHODSAnalyzing the reports of hospitalized laboratory-confirmed influenza cases of children under 15 years old who were detected by the sentinel surveillance systems in 10 provinces from December 2009 to June 2014. Such data as their demographic, medical history, clinical symptoms and signs, treatment and outcome were collected using questionnaires, with their clinical characteristics and their risk factors of influenza infection described.

RESULTSOf the 2 937 severe acute respiratory infection inpatients, 190 (6.5%) were laboratory-confirmed influenza cases. 123 (64.7%) of such confirmed cases were male, and 139 (73.2%) were children under 5 years old, with age median of 3.0 years (IQR: 1.0-5.0 years). 20 (10.5%) of them had at least one chronic medical condition, mostly chronic cardiovascular disease (3.2%), immunosuppressive disease (3.2%), and cancer/tumor (2.6%). Most common clinical symptoms of the cases were fever (92.6%) and cough (88.8%), of which abnormal pulmonary auscultation (51.1%) and abnormal chest X-ray performance (36.1%) were the most common clinical signs. 29 cases (15.8%) had complications, of which pneumonia (15.3%) was most common. 16 cases (8.6%) used antiviral drugs, and 4 cases (2.2%) were admitted into ICU. Risk factor analysis suggested that age < 6 months (OR = 0.406, 95% CI: 0.203-0.815) was a protective factor against influenza infection; and age 5-9 years old (OR = 2.535, 95% CI: 1.059-6.066) was a risk factor for influenza infection.

CONCLUSIONHospitalized laboratory-confirmed influenza cases were found mostly in children under 5 years old. Risk exposure for influenza infection varied among age groups.
