摘要 目的:研究氧敏感电压门控性钾离子通道亚型Kv1.5与Kv2.1在通气功能正常和通气功能中度以上异常患者肺细小动脉的基因表达差异。方法:收集肺癌患者行肺叶切除距肿瘤5cm以外的肺组织块,体式解剖显微镜下分离肺细小动脉,液氮速冻后放入-80℃冰箱冻存,提取RNA,逆转录后应用实时定量PCR(real-time PCR)对Kv1.5及Kv2.1基因进行扩增,并计算在通气功能正常组与通气功能中度以上异常组的表达差异。结果:通气功能中度以上异常组Kv1.5与Kv2.1的基因表达均低于通气功能正常组,差异有统计学意义(P<0.05)。结论:通气功能中度以上异常患者肺细小动脉Kv1.5与Kv2.1的基因表达下调,可能进一步影响Kv1.5与Kv2.1离子通道蛋白的表达。
