背景及目的动脉硬化闭塞症(ASO)是外周血管动脉粥样硬化导致组织血流减少血管闭塞的一种疾病。ASO病因复杂,涉及遗传和环境诸多因素。据猜测许多基因可能与ASO发病有关,但是各种基因假说缺少证据支持。最近一些研究发现,精氨酸酶Ⅰ(ArgⅠ)可能与动脉粥样硬化的个体易感性性有关。ArgⅠ编码基因位于6号染色体短臂2区3带(6q23),长11.5kb,包含8个外显子,编码322个氨基酸生成蛋白质。当前有研究发现,位于启动子序列的Argrs2781666G/T碱基变异与法裔人群颈动脉内膜中层增厚(CCA-IMT)相关。种群背景对基因多态性及疾病都存在影响。因此,我们通过查询NationalCenter...Background & Aims Arteriosclerosis obliterans (ASO) is a disease caused by the blocking of blood flow as a result of arteriosclerosis in the peripheral artery.ASO is a complex condition, resulting from genetic and environmental contributions.Many genes are suspected to be involved in its aetiology. Most, however, the genes theory lack of evidence to support. Some very recent studies support a role...学位:医学硕士院系专业:医学院临床医学系_外科学学号:2452009115297
