摘要:

【摘要】背景 机械通气相关性肺损伤(ventilator induced lung injury,VILI)是机械通气治疗中常见的严重并发症,过度牵拉引起的细胞机械应力是由细胞骨架以及细胞-细胞间和细胞-细胞外基质的相互作用调节完成。目的 探讨细胞骨架在机械通气相关性肺损伤中的病理生理机制,丰富和完善VILI理论。 内容 此文描述了机械通气刺激被转化为细胞内的生理信号,从而诱导细胞活化、增加肺血管通透性导致肺损伤。对细胞骨架与机械应力在机械通气相关性肺损伤中的病理生理作用进行详尽的阐述。趋向 关于细胞骨架及其相关结构在VILI的病理生理变化中作用的体外研究已广泛开展,但体内VILI模型较少,需进一步的研究

Abstract:

【Abstract】 Background Although mechanical ventilation is an important therapy, it can result in complications. Cellular mechanotransduction of the overstretching stimulus is mediated by means of the cytoskeleton and its cell-cell and cell-extracellular matrix interactions。Objective The aim of this review is to investigate the effect of cytoskeleton and mechanotransduction in the pathophysiology of ventilator-induced lung injury. Content This paper describe the mechanical stimulus of ventilation is translated into an intracellular biochemical signal, inducing endothelial activation, pulmonary vascular permeability and lung injury. The review has been focused on the cytoskeleton and mechanotransduction in the pathophysiology of ventilator-induced lung injury. Trend although the cytoskeleton plays a fundamental role in the pathogenesis of ventilator-induced lung injury, there have been few in vivo studies of alterations in the cytoskeleton and in cytoskeleton-associated proteins during this pathological process, More research on VILI is still worth exploring to meet clinical patients need.
