<h4>Objectives</h4>We aimed to demonstrate that electroacupuncture (EA) alleviates vascular cognitive impairment (VCI) induced by cerebral ischemia in rats by modulating oxygen homeostasis and energy metabolism through the HIF-1α/p53/NGB signaling pathway.<h4>Materials and methods</h4>Male Sprague‒Dawley rats underwent bilateral common carotid artery occlusion (BCCAO) to establish a VCI model. This evidence concerns the gene TP53 and Cerebral ischemia.
