Objective:To discuss the application of Roche ECL instrument E601 in inspection serum markers of myocardial injury aspects.Methods: Dependent on the clinical experience of cardiology, the introduction of Roche E601 methodology and the instruments using, and the clinical significance analysis of myocardial injury markers, summarized the important considerations in accurate test results and clinical judgment when using ECL instrument checks serum markers of myocardial injury.Results: In order to make better clinical application, people who use Roche ECL instrument E601 should pay attention to proper storage and use reagents, note the use of the combined reagents and the clinically meaningful of detected projects. Conclusion: The quality control of technical procedures is very important to assure the testing results. Only understanding some of the important considerations,can we better integrate the device for clinical application.

Objective To investigate the effects of endogenous estrogen on blood glucose level,serum insulin level,and plasma total antioxidant capacity in streptozotocin-induced diabetic female mice,and to explore possible protective effects of estrogen on pancreatic islet cells.Methods Female mice were randomly according to body weight divided into four groups:( 1 ) Sham( Sham operation and vehicle administration) ; ( 2 ) Ovx( ovariectomy and vebicle administration ) ; ( 3 ) Sham + STZ ( Sham operation and STZ administration ) ; and ( 4 ) Ovx + STZ ( ovariectomy and STZ administration).The diabetic mice were induced by intraperitoneal injection of streptozotocin (STZ,50 mg/kg ).Blood glucose levels were measured once a week.Results The blood glucose level and malondialdehyde of Ovx group were higher than that in Sham group,while total anti-oxidant capacity ( T-AOC ) was lower than those in Sham group.the blood glucose level and MDA of Ovx+ STZ group were higher than those in Sham +STZ group,while T-AOC and serum insulin level were lower than those in Sham + STZ group.Conclusions Endogenous estrogen may have some protective effects on pancreatic islet function from streptozotocin-induced diabetes mellitus in female mice.
