摘要
肺组织局部的肾素一血管紧张素系统(RAS)与急性呼吸窘迫综合征(ARDS)关系密切,血管紧张素Ⅱ(AngⅡ)通过其1型受体激活肺部炎症反应,促进ARDS发生发展。血管紧张素(1—7)Ang-(1-7)]也是RAS中得重要重要组分之一,能拮抗AngⅡ的生物学作用,被认为是AngⅡ的内源性拮抗剂。在ARDS中,Ang-(1-7)可能通过抑制炎症反应、减轻肺组织纤维化以及抗肺动脉高压等途径发挥肺保护作用,在ARDS中具有广阔的应用前景。
It has been demonstrated that renin angiotensin system (RAS)was involved in the pathogenesis of acute respiratory distress syndrome (ARDS). Angiotensin Ⅱ(Ang Ⅱ ), which is the main effector of RAS, cotdd activate pulmonary inflammation through its receptor ATIR in ARDS. While recent findings has suggested that Angtensin (1-7)fAng (1-7)] ,the endougenous antagonist of Ang Ⅱ in RAS, could counter-regulate some pathological changes of Ang Ⅱ such as inflammation, fibrosis and pulmonary hypertension. These results indicate that Ang-(1-7) may protect from ARDS. In this review, we will focus on the recent findings related to the potential beneficial aspects of Ang-(1-7) in ARDS.
