[Eye-acupuncture ameliorates ferroptosis of cerebral neuronal cells in CIRI rats by up-regulating System xc(-)-GSH-GPX4 antioxidant functional axis activities].

Objectives: To observe the effect of eye-acupuncture on the antioxidant function axis：System xc(-)-glutathione-glutathione peroxidase 4 (System xc［-］-GSH-GPX4) in the cortical tissue of ischemic penumbra of acute cerebral ischemia-reperfusion injury (CIRI) rats, so as to explore its underlying mechanism in improvement of CIRI by ameliorating the ferroptosis of neurons via antioxidant function axis.

Methods: Male SD rats were randomly divided into sham operation, model, eye-acupuncture and GPX4-inhibitor groups, with 15 rats in each group. The CIRI model was replicated by occlusion of the middle cerebral artery and reperfusion for 24 h.
