ABSTRACT
Objective:To investigate the clinical significance of dynamic analysis of plasma brain natriuretic peptide in patients with dilated cardiomyopathy with chronic heart failure.Methods:Ninety patients with dilated cardiomyopathy with chronic heart failure admitted into our hospital firom March 2012 to March 2016 were divided into group A (20 cases),group B (38 cases),and group C (32 cases) according to the NYHA grading.The plasma BNP levels and LVEF,LA,LVEDD,and LVESD in the three groups were detected and compared.The correlation of plasma BNP and cardiac function and ultrasonic cardiogram indexes were analyzed.And the capability of plasma BNP and LVEF in diagnosis of patients were analyzed and compared.Results:The plasma BNP level in group C was markedly higher than that of group A and group B (P＜0.05),and that in group B was much higher than that of group A (P＜0.05).And LA in group C was significantly higher than that of group A (P＜0.05),while differences in LVEF,LVEDD,and LVESD were not obvious (P＞0.05).The plasma BNP was positively correlated to NYHA grading,but had no significant correlation with the LVEF,LVEDD,LVESD,and LA (P＞0.05).Based on results of receiver operating characteristic curve analysis,plasma BNP =523.5 pg/mL was the threshold value for identification of patients with NYHA Ⅲ and Ⅳ (AUC=0.901,P＜0.001),while LVEF had not the capability (AUC=0.392,P=0.276).Conclusion:Detection of plasma BNP level had important clinical significance on diagnosis,screening and cardiac functional grading of patients with dilated cardiomyopathy with chronic heart failure.
ABSTRACT
Objective To reduce the management risk of operational narcotics in the operation room .Methods System of in-formation management for RFID turnover box was developed with RFID technology based on the establishment of narcotic operation pharmacy;system function was achieved through applying the response of RFID to the process of obtaining and employing modular med -icine cabinet for anesthesia connecting fingerprint door-lock system.Results Narcotic operation pharmacy was equipped with 6 kinds of medicine cabinet .A total medicine cabinets of 62 can meet the demands of 120 operations per day .Conclusion Modular medicine cabinet for operation based on the response of RFID technology decreases the cost of drug management and promote the efficiency and management standardization .
