The present study aimed to investigate the effects of YXJF on memory impairment in a rat model of cerebral ischemia/reperfusion-induced VaD and to explore the underlying mechanisms, including anti-apoptotic effects and enhancement of cAMP/PKA/CREB signal transduction, which provided convincing evidence for the clinical efficacy of YXJF. The gene discussed is CREB1; the disease is memory impairment.
