【摘要】Objective To investigate the effect of CD151 gene therapy on improving myocardial function in swines with myocardial infarction. Methods CD151, antisense CD151 and green fluorescent protein (GFP) were constructed into the recombinant adeno-associated virus (rAAV). Swines were divided into 4 groups: rAAV-GFP group (6 swines), rAAV-CD151 group (6 swines), rAAV-antiCD151 group (6 swines) and control group (6 swines). The swines were performed with coronary artery ligation and intramuscularly injection with rAAV. Eight weeks after vector administration, western blot was used to detect gene expression of CD151. 13N-labeled NH3 positron emission tomography (PET) was used to evaluate myocardial perfusion. Echocardiography was used to assess myocardial function. Results Compared with the control group and the rAAV-GFP group, the rAAV-CD151 group showed higher CD151 protein expression. Compared with the rAAV-GFP group, the defect size of myocardium was decreased[( 11.3±2.4)% vs. (21.1±2.6)%, t= -5.67,P<0.01] and left ventricular ejection fraction (EF), left ventricular fractional shortening (FS), the ratio of anterior lateral wall thickening (△ALWT) and ratio of interventricular septum thickening (△IVST) were
