Résumé
Objective:To assess the accuracy of the portable blood glucose meters. Methods:The study design was equivalent clinical trial. The participants were selected according to the inclusion and exclusion criteria from inpatients, outpatients and outpatient volunteers of the department of endocrinology. The fingertip blood glucose was measured by five portable blood glucose meters and compared with vein blood glucose measured by biochemistry. The measurement error was assessed by the mean difference with biochemical results. The correlation coefficient was calculated to test the correlation between fingertip and vein blood glucose. Results:there were 230 cases in total including 86 males and 144females. The average age was (50.6±13.5) years old. There were 73 fasting blood glucose and 157 postprandial blood glucose. The range of biochemical blood glucose value was from 2.19 to 19.95 mmol/L and the averaged biochemical blood glucose concentration was (6.77±2.65) mmol/L. The minimum measurement error was 0.08mmol/L measured by blood glucose meter C. However, there was one meter E whose 95%confidence interval of measurement error exceeds the equivalent interval (-0.83, 0.83) mmol/L range and the difference does not meet the clinical equivalence. The measurement bias was all lower than 95%. Conclusion:The blood glucose meters can be used as the day-to-day monitoring of blood glucose in patients. The accuracy needs to be improved and continuously monitored.

OBJECTIVE To analyze the quality of the disposable sterile medical appliances befoure used and give suggestions for managements.METHODS The acceptance process of the disosable sterile medical appliances during the past five years wes restropectively analyzed and the unqualified products were found out.RESULTS After examination of the sterile medical devices,the main problems were more ethylene oxide residues,packaging damaged,expiry date not clear,both within and outside the Model not matching the registration of medical device product number.Categories not matching the product and so on.CONCLUSIONS The above problems are not meet the national laws and regulations,and should be timely and effective monitored to achieve safety use of medical device.

Objective: To study the relationship between depression and side effects of hemodialysis in elderly patients Method: 19 elderly patients and 32 adult patients regularly receiving hemodialysis completed SDS (Zung's Self-rating Depression Scale) Side-effects (complications) during their hemodialysis were recorded Results: Elderly patients had more complications than adult, such as hypertension, hypotension, headache, vomiting, ventricular and atrial arrhythmia (P60 had more above complications than elderly with SDS60, elderly had more hypotension, atrial or ventricular arrhythmia and less vomiting than adult Conclusion: In the period of hemodialysis, elderly patients with depression has more complications
