Objective On the background of the clinical skills competition for national medi-cal students in the higher medical colleges and universities, to investigate medical students' mastery of hand hygiene knowledge and skills, explore the effective methods of teaching, and improve the medical students' hand hygiene compliance and accuracy in clinical practice. Methods 90 medical students at a tertiary-level teaching hospital clinical practice stage were randomly selected for the study, and performed hand hygiene theoretical knowledge and practical skills training in special education. Special teaching investigation was made before and after training, to investigate the students' hand hygiene compliance rate in clinical practice. And the correct rate of hand hygiene were examined and medical students' hand hygiene compliance rate and correct rate were compared before and after the special teaching and training. Statistical analysis was made by using chi square test 2. Results After theory teaching and additional special skills training the students' hand hygiene compliance and accuracy were improved significantly (79.00%vs. 35.50%, P=0.000). The correct rate of hand hygiene was also significantly higher than before training (92.22% vs. 61.11%, P=0.000). Conclusion Hand hygiene knowledge and skills training can significantly improve the medical students' hand hygiene compliance and accuracy in the clinical practice, and is conducive to the prevention of the spread of infection in hospitals, and then reduce the incidence of hospital infection.

In accordance with the General Hospital Accreditation Standards Ⅲ (2011) and other HAI-related hospital guidelines,a quantitative assessment index system for infection control of general hospitals has been established.Based on these,departmental performance of the hospital has been regularly checked in their infection control,and the outcomes of assessment included into the performance appraisal system of the hospital.Thanks to this practice,there have been no outbreaks of hospital associated infections in the hospital in recent two years,the incidence of hospital associated infection decreased from 1.25％ in 2012 to 1.05％ in 2013.Proper hand hygiene rates,compliance rates increased from 45.3％ and 26.9 ％ in 2012 to 92.4 ％and 65.5 ％ in 2013.The index system for evaluating prevention and control of hospital associated infection is scientific and effective.

Objective To explore the investigation and control method for the epidemic of surgical site infection (SSI)in a hospital.Methods Data of orthopedics patients receiving clean wound orthopedics operation were ana-lyzed retrospectively,and effective measures were taken to control the epidemic of HAI.Results From June to August 2012,a total of 312 patients received clean wound orthopedics operation,7 (2.24%)SSI cases occurred.SSI rates during the same period from 2009 to 2012 were significantly different(P <0.05),and was the highest in 2012. HAI management staff reviewed patients’medical records,communicated with staff in orthopedics department,and put forward advice for SSI control;orthopedics department worked out and implemented detailed infection control measures.The subsequent surveillance showed that the prevalence of SSI in orthopedics ward decreased to 0.38%, infection outbreak was effectively controlled.Conclusion HAI management department played an important role in the finding and control of HAI outbreak.Scientific analysis on monitored data and proper measures adopted by HAI management department and clinical department can effectively control HAI outbreak.

Routine supervision on hospital infection control was normally fed back on paper-based media,plagued by low efficiency and poor traceability.A feedback process developed with Workflow technology,can loop the entire process ranging from routine supervision to identifying loopholes,to hospital infection and joint development of correctional measures clinically,all the way to implementation of infection control practice and sustained improvement.The closed-loop PDCA cycle management features greater efficiency and traceability in hospital management of its infection control,and builds a quality improvement model featuring close communication between infection control department and clinical departments.

Objective:To study the effects of obesity induced by high-fat diet on T lymphocyte subsets in the adipose tissue in mice.Methods:C57BL/6 male mice were randomly divided into 2 groups, the normal control group and high-fat diet group.After feeding 16 weeks, serum was separated and CHOL, TG, HDL, LDL and glucose levels were measured by automatic biochemical analyzer.The concentrations of TNF-αwere determined by ELISA kit.FACS was used to analyze the number of T cells and the percentage of subgroup in epididymal fat adipose tissue.Results:Compared with control group,body weight,weight gain,epididymal fat pad weight,perirenal fat weight,blood lipids,glucose and TNF-αwere significantly increased in high-fat diet group,but there were no difference in the thymus index and spleen index between the two groups.Compared with the control group,the mice fed a high-fat diet had increasing proportion of CD3+T cells,CD4+T cells and CD8+T cells in adipose tissue and there was a significant increase on the proportion of Th1 and Th17 sublineage in the HFD group.Conclusion:High-fat diet induced obesity can lead to the increasing proportion of CD3+T cells,CD4+T cells and CD8+T cells in epididymal fat pads and generate a progressive Th1 and Th17 bias.

Objective To investigate the characteristics of healthcare-associated infection(HAI) in elderly hospitalized patients,and analyze the risk factors for HAL Methods Incidences of HAI in elderly(elderly group) and non-elderly hospitalized patients (control) in a tertiary first-class hospital were investigated,the underlying diseases,infection sites,department distribution and so on between two groups of patients were compared.Results The incidence of HAI in elderly group was higher than that in control group(3.38 ％ vs 1.45 ％,P＜0.05);the proportions of hypertension and diabetes mellitus in elderly group was higher than control group,while cerebrovascular disease was lower than control group.The proportion of lower respiratory tract infection,urinary system infection and antimicrobial-associated diarrheal in the elderly were higher than control group(41.62％ vs 28.00％,15.44％ vs 12.02％,6.03％ vs 3.15％,respectively).The incidence of catheter-associated urinary tract infection in the elderly group was higher than that in control group(6.85‰ vs 3.95‰,RR95％CI =1.209-2.485,P＜0.05).The proportion of HAI in the elderly group in internal medicine departments was higher than that in control group (52.71％ vs 40.03％),while in intensive care unit was lower than control group (33.52％ vs 41.19％).Conclusion The characteristics of HAI in elderly patients are closely related to their demographic characteristics,early prevention of HAI in key sites should be carried out according to its characteristics.
