文题释义:
自噬体标记蛋白Beclin-1:
其参与了脑出血引起的的细胞凋亡变化,其发生的轻中度自噬对于脑出血起到了保护作用。Beclin-1调节机制中最主要的即是PI3K调节,与PI3K的磷酸化密切相关。
补阳还五汤:中华传统医学认为其具有补气活血、祛瘀通络之功效,可作为治疗气虚络瘀证之脑卒中后遗症的常用方药。大量研究表明补阳还五汤的作用机制广泛,其在改善血液流变、抗血栓形成、抗动脉粥样硬化、血管性脑病中降低兴奋性氨基酸毒性、抑制细胞凋亡、抑制自由基的产生及抗脂质过氧化等方面发挥着重要作用。

 

摘要
背景:
补阳还五汤是治疗脑出血的临床常用药,前期研究已发现其出色的神经保护作用,能够高效的抑制神经细胞凋亡。自噬活动与神经细胞凋亡关系密切,CXCR4-PI3K自噬信号传导通路在少许的临床常用药中已得以验证,然而关于补阳还五汤对其影响却知之甚少;同时对于Beclin-1在补阳还五汤神经保护的研究中尚未见报道。
目的:探究补阳还五汤对脑出血大鼠脑组织CXCR4-PI3K自噬信号传导通路与Beclin-1的影响及其相关机制。
方法:按照Rosenberg法复制脑出血大鼠模型,以补阳还五汤灌胃给药,采用Western blot法检测Beclin-1蛋白,免疫组化方法检测PI3K、AKT、基质细胞衍生因子1、CXCR-4蛋白表达,TUNEL法检测细胞凋亡情况。
结果与结论:①补阳还五汤灌胃给药后,能够减轻脑出血大鼠神经细胞凋亡数量,在脑出血发生后几小时上调Beclin-1、PI3K、AKT、基质细胞衍生因子1、CXCR-4等蛋白的表达,发挥脑保护效果;②补阳还五汤能够激活CXCR4-PI3K自噬轴信号传导通路,既能够激发细胞自噬,又能够调控细胞自噬状态,实现抑制细胞凋亡的脑保护作用。

Abstract:

BACKGROUND: Buyang Huanwu Decoction is commonly used in clinical medicine in treatment of intracerebral hemorrhage. Previous studies have been found that it has excellent neuroprotective effect, can efficiently inhibit the apoptosis of nerve cells. Autophagic activity is closely related to apoptosis of nerve cells. CXCR4-PI3K autophagy signaling pathway has been verified in clinic. However, the effect of Buyang Huanwu Decoction is poorly understood. There is no study on Beclin-1 in the neuroprotective studies of Buyang Huanwu Decoction. 
OBJECTIVE: To explore the effects of Buyang Huanwu Decoction on CXCR4-PI3K autophagy signaling pathway and Beclin-1 in rats with cerebral hemorrhage and related mechanisms. 
METHODS: According to Rosenberg method, a rat model of cerebral hemorrhage was replicated and intragastrically administered Buyang Huanwu Decoction. Western blot assay was used to measure Beclin-1 protein. Immunohistochemical method was utilized to detect the expression of PI3K, AKT, stromal cell derived factor 1 and CXCR-4 protein. TUNEL assay was applied to identify apoptosis. 
RESULTS AND CONCLUSION: (1) After administration, Buyang Huanwu Decoction could reduce the number of neuronal apoptosis in rats with intracerebral hemorrhage, up-regulate the expression of Beclin-1, PI3K, AKT, stromal cell derived factor 1, and CXCR-4 protein, and exert neuroprotective effect. (2) Buyang Huanwu Decoction could activate CXCR4-PI3K autophagy signal transduction pathway, both to stimulate autophagy and to regulate autophagy state, can inhibit apoptosis, and exert cerebral protective effect.
