ABSTRACT
Objective@#To understand the present situation of physical activity and its influencing factors, and to provide a reference for improving the level of physical activity and making the intervention measures.@*Methods@#The method of random stratification was used to select 4 740 pre school children aged 3-6 from 17 kindergartens in 12 counties and districts of Nanchang City, The questionnaire of physical activities of young children and the questionnaire of parents of physical activities of young children were applied to conduct a survey.@*Results@#Compared with weekday PA and MVPA, preschool children’s weekends decreased, SB increased. The differences in PA, MVPA and SB on weekdays and weekends were statistically significant( P <0.01). The proportion of PA and MVPA reaching the recommended amount during the working day of preschool children were 44.9%-59.2%, 45.4%- 61.7%.The proportion reaching the recommended amount of PA and MVPA on weekends were 24.7%-27.8%, 24.5%-29.9%, and the proportion reaching the recommended amount on weekdays was higher than that on weekends.@*Conclusion@#There is still gap between actual amount of physical activity and the recommended amount. There are different modes of activity on weekdays and weekends, and weekends are the least active periods. Parents and teachers should pay enough attention to the establishment of "social campus family" model to improve the lack of physical activity of preschool children.
ABSTRACT
Objective@#To analysis HIV infection status among volunteer blood donors in Shaoxing area from 2001 to 2014, and to provide evidence for recruiting strategy of volunteer blood donors.@*Methods@#A statistical analysis was conducted on the confirmed HIV-positive cases of volunteer blood donors from 2001 to 2014 in Shaoxing area.@*Results@#36 volunteer blood donors were confirmed anti-HIV positive, and the positive rate was 0.09‰. Only 1 volunteer blood donor was confirmed anti-HIV positive before 2006, and the HIV-positive rate rose and the changes in volatility after 2006. The HIV-positive rate in Zhuji was highest compared to other blood center of Shaoxing. The HIV-positive rate in male and female were 4.14∶1, men who had sex with men remain at great risk for HIV infection.@*Conclusions@#Anti-HIV positive rate was lower among volunteer blood donors in Shaoxing area. Since 2006 years, anti-HIV positive rate increased. The anti-HIV positive rate were different in the different blood center in Shaoxing area, HIV antibody confirmatory positive is more common in young males volunteer blood donors.
ABSTRACT
Objective To improve the protective strategy of occupational risks for technicians in blood centers so as to ensure their health and safety.Methods The occupational risk factors were analyzed by the 5W1H method,and the corresponding protective measures were introduced.Then,the protective measures were verified dynamically by the PDCA circulation,and were standardized and further spread.The projects with poor effect were replanned and entered the PDCA recycling.Results The system of the 5W1H method combined with PDCA circulation could identify and control various occupational risks,and effectively prevent the occupational detriments.Condusion Combined application of the 5W1H method with PDCA circulation is an effective way to protect the health and safety of technicians in blood centers and an effective mode to improve the management of occupational risks.
ABSTRACT
Objective: To explore the peri-operative application of GLP-1 analogue and insulin on myocardial perfusion and clinical prognosis in patients of acute ST segment elevation myocardial infarction (STEMI) with stress-induced hyperglycemia. Methods: Our research was a prospective single center randomized control study. A total of 114 consecutive STEMI patients received percutaneous coronary intervention (PCI) within 12h of onset were enrolled, the patients had no diabetes while blood glucose ≥11.1mmol/L at immediate admission. Based on random number table, the patients were divided into 2 groups: Observation group, the patients received GLP-1 analogue, n=59 and Control group, the patients received insulin, n=55. The post-operative myocardial perfusion, indicators of myocardial damage and cardiac function, myocardial infarct area (MIA) and myocardial salvage index (MSI) were compared between 2 groups. The patients were followed-up for 6 months to record the incidence of major adverse cardiovascular events (MACE). Results: At peri-operative period, compared with Control group, Observation group had decreased peak values of creatine kinase isoenzyme (CK-MB) and troponin T (cTnT), P<0.05. At 6 months post-operation, compared with Control group, Observation group showed increased myocardial perfusion and left ventricular ejection fraction (LVEF), P<0.05, reduced MIA (15±12) g vs (20±14) g, P<0.05 and 12% elevated MSI as (0.64±0.13) vs (0.56±0.12), P<0.001. The MACE incidence was similar between 2 groups, P=0.217. Conclusion: In STEMI patients with stress-induced hyperglycemia, peri-operative application of GLP-1 analogue may safely regulate blood glucose, improve cardiac perfusion and function, reduce MIA; while it had no influence on myocardial perfusion at peri-operative period and no impact on MACE occurrence at 6 months post-operation.
