ABSTRACT
BACKGROUND:
Buyang HuanwuDecoction is commonly used in clinical medicine in treatment of intracerebral hemorrhage. Previous studies have been found that it has excelent neuroprotective effect, can efficiently inhibit the apoptosis of nervecels. Autophagic activity is closely related to apoptosis of nerve cels. CXCR4-PI3K autophagy signaling pathway has been verified in clinic. However, the effect of Buyang HuanwuDecoction is poorly understood. There is no study on Beclin-1 in the neuroprotective studies ofBuyang HuanwuDecoction.OBJECTIVE:
To explore the effects ofBuyang HuanwuDecoction 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 intragastricaly administeredBuyang HuanwuDecoction. Western blot assay was used to measure Beclin-1 protein. Immunohistochemical method was utilized to detect the expression of PI3K, AKT, stromal cel derived factor 1 and CXCR-4 protein. TUNEL assay was applied to identify apoptosis. RESULTS ANDCONCLUSION:
(1) After administration,Buyang HuanwuDecoction could reduce the number of neuronal apoptosis in rats with intracerebral hemorrhage, up-regulate the expression of Beclin-1, PI3K, AKT, stromal cel derived factor 1, and CXCR-4 protein, and exert neuroprotective effect. (2)Buyang HuanwuDecoction 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.
