Objective: To evaluate the relationship between the levels of serum uric acid (SUA) and prevalence of coronary artery disease (CAD) by Meta analysis. Methods: We searched the databases of Pub Med, Elsevier and Web of Science for internationally published cohort study for the relationship between SUA levels and CAD prevalence and conducted a general analysisby using Stata software. Results: A total of 11 cohort study including 463,918 subjects were enrolled in this study. For both male and female genders, increase SUA level was the risk factor for CAD occurrence (RR=1.11, 95% CI 1.00-1.24) and (RR=1.24, 95% CI 1.15-1.34). Dose-response Meta-analysis indicated that by 1 mg/dl SUA elevation, the risk of CAD occurrence would increase 4.8% in male and 12.4% in female, the risk in female gender was higher than male. Conclusion: SUA level has been closely related to CAD prevalence.

Objective To establish the standard values of indicators for care quality evaluation of benign prostatic hyperplasia. Methods To acquire data of nurses configuration in 24 hospitals nationwide by the status survey method. On-spot examination, questionnaire, case-review methods were applied to determine the standard values of 638 benign prostatic hyperplasia patients' care quality in Xi'an three major general hospitals.

Objective To establish the benign prostatic hyperplasia evaluation index system for nursing quality. Methods Indicators framework for perioperative nursing quality evaluation index system was built up by the theoretical research, clinical research, expert meetings approach firstly, then the Delphi method was used to screen and verify the indicators. Results Two rounds of consultation questionnaires were collected with rate of 86.0%, 95.3% respectively, the first round of consultation had the retention of 13 indicators, removed 4 indicators of those. After the second round, the average score of important target was no less than 8.0, and more than half of indicators had a full mark, coefficient of variation targets no higher than 0.20 were up to 100%. Coefficient of concordance of two rounds were 0.241 and 0.433 respectively. ConclusionsAfter two rounds of consultation, there were 13 quality indicators left and experts had well authoritativeness and representative.
