Abstract

Apoptosis and the dysfunction of the cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA)/cAMP-responsive element binding protein (CREB) signaling pathway have a key role in memory impairment in vascular dementia (VaD), a challenging clinical problem. Yifei Xuanfei Jiangzhuo formula (YXJF), a Chinese herbal decoction, has been used to treat VaD in clinical practice and has produced positive outcomes; however, convincing evidence is currently lacking. The present study aimed to investigate the effects of YXJF on memory impairment in rats with cerebral ischemia/reperfusion and to explore the underlying mechanism. YXJF ameliorated memory impairment in rats with cerebral ischemia/reperfusion, inhibited hippocampal apoptosis in a dose-dependent manner and attenuated increases in the protein expression of B-cell lymphoma 2 (Bcl-2)-associated X protein as well as c-Jun and a reduction in Bcl-2 protein expression in the hippocampal tissue of the rats. Furthermore, administration of YXJF significantly increased the protein expression of PKA C-α and CREB, and promoted CREB phosphorylation. The results indicated that YXJF improves memory impairment through inhibiting apoptosis and enhancing PKA/CREB signal transduction in rats with cerebral ischemia/reperfusion.
