当代广泛的流行病学调查研究表明,脑血管病已是一种主要的致死的常见病。在脑血管病中,脑水肿是基本病理改变之一。水通道蛋白-4(AQP4)是近10年来发现的膜通道蛋白之一,在脑水肿的病理生理变化中发挥重要作用,而Ca2+超载常是造成神经细胞坏死的最后通道。1脑水肿的概述脑水肿为 Contemporary epidemiological studies have shown that cerebrovascular disease is a major lethal common disease. In cerebrovascular disease, brain edema is one of the basic pathological changes. Aquaporin-4 (AQP4) is one of the membrane-channel proteins found in the past 10 years. It plays an important role in the pathophysiological changes of cerebral edema. Ca2 + overload often leads to the death of nerve cells. An Overview of Brain Edema Brain edema is
