[Effect of electroacupuncture of different acupoint groups on cerebral cortical neurovascular unit and PI3K/Akt signaling in rats with ischemic stroke].

Objective: To observe the protective effect of electroacupuncture (EA) on neurovascular unit, neurological function in rats with cerebral ischemia (CI), so as to explore its mechanisms underlying improvement of ischemic cerebral tissue.

Methods: Male SD rats, SPF grade, were randomly and equally divided into sham operation group, model group, EA group Ⅰ and EA group Ⅱ，27 rats in each group. The CI model was established by occlusion of the middle cerebral artery (MCAO).
