ABSTRACT
Objective: To determine the distribution characteristics of waist circumference (WC), waist height ratio (WHtR) of 6–18 years olds in Guangzhou, and to put forward the WC and WHtR appropriate boundary values for 6–18 years olds on the basis of cardiovascular disease (CVD) risk factor assessment. Methods: We analyzed the height, weight, WC and its metabolic indication data (blood pressure, fasting blood glucose, and blood lipids) of 15 000 children in Guangzhou, aged 6–18, with the receiver-operating characteristic curve (ROC), and explored the best value point of WC and WHtRfor the prediction of cardiovascular diseases. Results: When the WC percent reached P85, and WHtR reached 0.48, the cardiovascular risk factors of fasting blood-glucose, blood pressure, and blood fat were signiifcantly higher. Conclusion: The 85th percentile value of WC and 0.48 of WHtR are the appropriate boundary values in increasing the cardiovascular disease risk factors in Chinese children and teenagers. WC and WHtR as a relatively simple inspection method, can well predict cardiovascular diseases, and be used in the conventional measuring items among students.
ABSTRACT
OBJECTIVE Passing through the investigation of disposable syringes use condition, to determine amount of syringes used in the hospital and extent of their contact with blood and body fluids, and to assess their waste polluted condition. METHODS By our hospital computer charge system, from May 1, 2006 to Apr 30, 2007 The used syringes were calculated. RESULTS A total of 923 676 plastic disposable syringes were used; from them 6 801 (0.74%) were contaminated by blood, an other body fluids (urine, gastric secretion, cerebrospinal fluid, and wound drainage) or cells, 16 892 (1.83%) were by anticancer drugs and 160 461(17.37%) were with different injections or contrasts. 739 522(80.06%)were utilized for dilute medicine in i.v. drip. CONCLUSIONS Eighty percent of syringes waste is without pollution, it can be used to regard as recycled resources.
ABSTRACT
OBJECTIVE To apply course management in disinfection and sterilization in hospital.METHODS The key points of disinfection and sterilization were investigated and found out.The flow of disinfection and sterilization was reconstructed,and the course management was actualized.RESULTS The hardware of disinfection and sterilization was improved,and the work efficiency and the percentage of pass were increased.CONCLUSIONS Course management is propitious to normal disinfection and sterilization in hospitial.
ABSTRACT
OBJECTIVE To explore the efficientcy of washing and sterilization methods for the endoscopic cell brush. METHODS The contaminated cell brush with the mixture of Bacillus subtilis var.niger spore and blood was washed by four methods:manually washing,multienzyme plus manually washing,ultrasonic cleaner washing,and multienzyme plus ultrasonic cleaner washing,and then dipped in glutaraldehyde for 5 h or 10 h,fumigated with glutaraldehyde for 5 h,and sterilized with 3M ethylene oxide box.The positive rates of occult blood test(OB test),the cleaning rates of B.subtilis var.niger spore and the sterilization eligibility ratio of four serilization methods were compared. RESULTS The washing method that multienzyme plus ultrasonic cleaner washing could clear effectively the contaminated cell brush that the positive rates of OB test was 0 and the cleaning rates of B.subtilis var.niger spore was 99.90%.The positive rates of OB test and the cleaning rates of B.subtilis var.niger spore of manually washing was 56.67% and 90.87%.Fumigated in 3M ethylene oxide box or dipped in glutaraldehyde for 10 h could kill all the spores,but dipped in glutaraldehyde for 5 h or fumigated with glutaraldehyde for 5 h could not. CONCLUSIONS The mixed contaminated endoscopic cell brush should be washed effectively by multienzyme+ ultrasonic cleaner washing,and should be sterilized by fumigated in ethylene oxide box or dipped in glutaraldehyde for 10 h.
