腹主动脉瘤炎症机制的研究进展

腹主动脉瘤是血管外科最高危的血管退化性疾病之一,其最严重的后果是由于薄弱的动脉管壁无法承受血流冲击,导致动脉瘤壁破裂,引起的猝死。随着我国人口老龄化形势日趋严峻,腹主动脉瘤的发病率也逐年上升,成为威胁我国人民生命健康的重要疾病之一。随着对腹主动脉瘤认识的进步,影像学检查手段的增多,该疾病的确诊率已大大提高,但其具体的发病机制仍不完全清楚。目前已知腹主动脉瘤的发生与吸烟、性别、氧化应激、基质蛋白酶、血脂等多种因素相关,最新的研究显示炎症反应在腹主动脉瘤的发生发展过程中起到重要作用,本文主要对腹主动脉瘤与白细胞相关的炎症反应机制的最新研究进展予以综述。

Advances in the Pathogenesis of Abdominal Aortic Aneurysms and Inflammation

Abdominal aortic aneurysm (AAA)is one of the most catastrophic arterial disease,with the severe outcome of sudden death due to the aortic rupture of weak arterial wall.Currently there is a lack of effective drug therapy for AAAs.Since the aging population situation is worsening,the prevalence of AAAs is rising constantly in China.There has already been plenty of factors known,which could led to AAA,however,the mechanism of AAA has not been very clearly.It has been recognized that many risk factors contribute to the development of AAA such as smoking,reactive oxygen species,matrix metallo-proteinase,and atherosclerosis,however,the mechanism of AAA formation has not been well under-stood.With the recent progressions in researches on inflammation and AAA,the role of inflammation in the pathogenesis of AAA has drawn increasing attention..This review will summarize recent advances in the investigations of leukocyte related mechanisms of aneurismal initiation and progression.
