Objective To explore the diagnostic performance of 64-slice spiral CT combined with exercise treadmill test for coronary artery disease ( CAD). Methods Eighty-six patients suspected of CAD were divided into low risk group, intermediate risk group and high risk group according to estimated pretest probabilities of CAD. All patients underwent coronary angiography, 64-slice spiral CT and exercise treadmill test. With coronary artery stenosis rate >50% as positive findings, the sensitivity, specificity, positive predictive value ( PPV), negative predictive value ( NPV) and accuracy of 64-slice spiral CT and 64-slice spiral CT combined with exercise treadmill test in diagnosis of CAD were calculated. Results With coronary angiography as the "golden criteria", the sensitivity, specificity, PPV, NPV and accuracy of 64-slice spiral CT in diagnosis of CAD were 95.2% , 88.6% , 88.9% , 95.1% and 91.9% , respectively. The sensitivity of low risk group, intermediate risk group and high risk group was 100% , 100% and 92.6%, specificity was 94.4% , 94.1% and 66.7%, PPV was 80.0%, 91.7% and 89.3%, NPV was 100% , 100% and 75.0%, and accuracy was 95.5% , 96.4% and 86.1%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of 64-slice spiral CT combined with exercise treadmill test in diagnosis of CAD were 97.6%, 97.7%, 97.6%, 97.7% and 97.7%, respectively. Conclusion 64-slice spiral CT combined with exercise treadmill test works well in screening CAD, especially for those with a low or intermediate estimated pretest probability.

Objective To learn the current capacity building of emergency response teams in Tianjin for the purpose of goals setting.Methods Health Emergency Capacity Questionnaire was issued to 89 secondary and above medical institutions and 19 CDCs in Tianjin.The form covered such items as basic institutional information, workforce makeup, emergency preparations, detection and early warning, emergency response, and summary/assessment.Data collected in the questionnaire were subject to descriptive and correlation analysis.Results Tianjin has scored an initial success in emergency medicine as evidenced in its emergency response mechanisms in place, elevated capacity in emergency medical rescue and disposal, and enhanced competence of emergency teams.Rooms of improvement however include insufficient professionalism and independence of health emergency, inadequate emergency commanding and decision making system functions, insufficient laboratory test capacity at district/county levels, and insufficient social involvement in health emergency.Conclusions Top-down design should be emphasized, health emergency response should be enhanced in terms of management and response planning system, while capacity building of the teams and long-term primary care emergency mechanism deserve higher attention.

Objective Hypoalbuminemia is a typical symptom of nephrotic syndrome ( NS) , which may result from the loss of much protein with urine.Hyperbilirubinemia is also a common symptom in patients with NS.This study is intended to reveal the relationship between hypoalbuminemia and hyperbilirubinemia in patients with NS by investigating urine bilirubin, albumin( ALB ) and 24-hour urine protein in the NS group, chronic glomerulonephritis ( CGN ) group and postoperative gastroparesis syndrome ( PGS) group ( ALB<35 g/L) .Methods Totally 187 patients with NS, 70 patients with CGN and 64 patients with PGS ( ALB <35 g/L ) were recruited before ALB, urinary protein ( UPR ) , urinary microalbuminuria/creatinine(Umalb/cr) and total bilirubin(TBIL) were detected.SPSS 17.0 Software was used to analyze the difference between the three groups and to reveal the correlations between TBIL and UPR, ALB.Results TBIL, ALB, UPR and Umalb/Cr levels were significantly different between NS, CGN and PGS groups ( one-way ANOVA test, P <0.05), and TBIL was positively correlated with ALB but negatively correlated UPR and Umalb/Cr in both NS and CGN groups (Spearman′s rho test,P<0.05);but no correlation was found between these items in PGS group (Spearman′s rho test,P>0.05) .Conclusion Serum bilirubin of patients with NS is at a low level and shows significant correlations with serum albumin and urinary protein levels.No similar association is found with the other two groups.The results in this study show that the causes of low serum bilirubin in patients with NS may related to the large amount of protein lost in urine.
