影响经皮冠状动脉成形术(ＰＴＣＡ)疗效的主要问题是再狭窄。其中血管壁平滑肌细胞(ＳＭＣｓ)增生过度是重要原因之一[1]。放疗在临床上可有效治疗良、恶性细胞增殖性疾病,据此,本研究用ＰＴＣＡ导管球囊灌注液相32Ｐ,对培养的兔髂动脉ＳＭＣｓ进行不同剂量单次照射,从细胞凋亡
The main problem affecting percutaneous transluminal coronary angioplasty (PTCA) efficacy is restenosis. Among them, vascular smooth muscle cells (SMCs) hyperplasia is one of the important reasons [1]. Radiotherapy is clinically effective for the treatment of benign and malignant cell proliferative diseases. Therefore, in this study, the liquid phase of 32P was infused with PTCA catheter balloon and the cultured iliac arteries of SMMCIs were exposed to single dose of different doses,
