ABSTRACT
Objective To explore the relationship between the level of tumor necrosis factor related apoptosis inducing ligand(TRAIL) and death receptor 5(DR5) and atherosclerosis(AS).Methods Eighty-three patients were divided into two groups: Sixty-one in the coronary artery disease(CAD) group and 22 in normal coronary artery group.Plasma soluble TRAIL(sTRAIL) and soluble DR5(sDR5) levels from these people were assayed by ELISA.The level of TRAIL and DR5 protein expression in coronary arteries were detected by immunohistochemisty statining.Results Plasma sTRAIL and sDR5 significantly increased in the CAD group(P
ABSTRACT
Objective To explore the diagnostic value of color Doppler echocardiography in the patients with anomalous origin of coronary artery.Methods Six patients were studied using color Doppler echocardiography.The origin sites,running courses,blood flow directions of coronary arteries, other accompanied cardiovascular abnormalities and valvular regurgitations were investigated.The diameters of coronary artery trunks and left ventricular ejection fraction (LVEF) were measured.And the results were compared with those of coronary angiography and surgery.Results Left coronary artery(LCA) originated from pulmonary artery(PA) in 4 cases,left anterior descending(LAD) branch originated from PA in 1 case,and accessory coronary artery originated from PA in 1 case.The main accompanied cardiovascular abnormalities included ventricular septum defect,atrial septum defect,complete endocardial cushion defect,and so on.For all the patients,the diagnostic results by echocardiography were consistent with catheterization and surgery.High correlations existed between echocardiographic and catheterization measurements for left and right coronary artery diameter and LVEF (r= 0.94 , 0.96 , 0.89 ,respectively,all P 0.05 ).Conclusions Color Doppler echocardiography can accurately diagnose the patients with anomalous origin of coronary artery, provide reliable information for surgical treatment.
