| 摘 要： | 目的: 探讨外源性肝细胞生长因子(HGF)基因转染高动力性肺动脉高压家兔后促进侧支肺血管生成、改善肺血流灌注、降低肺动脉压力的可行性。方法: 将肺动脉高压兔随机分为对照组、空病毒组和HGF基因转染组; HGF 基因转染组经气管内滴入法转染Ad-HGF, 对照组和空病毒组分别气管内滴入同体积PBS液和Adeno-Null; 4周后, 通过MacLab/8s多功能生理仪行血流动力学检测, 通过抗FⅧ+α-SMA抗体免疫荧光双标检测肺小动脉密度、FITC-lectin灌注+抗α-SMA荧光双标记了解肺血管灌注情况。结果: 气管内给药4周后, HGF基因治疗组含平滑肌细胞的小动脉密度较肺动脉高压对照组和空病毒组(12.5±2.7)/mm2明显增多(P<0.05); HGF组肺血流灌注获得有效改善, 而肺动脉高压对照组和空病毒转染组肺血管仍处于狭窄甚至闭塞状态; HGF治疗组肺动脉平均压明显低于肺动脉高压对照组和空病毒转染组(P<0.05)。结论: 肺动脉高压模型动物经气管滴入法转染外源性HGF, 可以促进肺侧支血管生成, 增加肺灌注并有效降低肺动脉压力。 |
