MTOR and Cerebral ischemia: In this study, we used rats with intermittent hypoxia preconditioning to prepare global cerebral ischemia-reperfusion models, observed the expression of mTOR/autophagy pathway and the loss and changes of nerve cells in the rat hippocampus and investigated its role in the aggravation of cerebral ischemia-reperfusion neuron injury caused by intermittent hypoxia, so as to provide experimental basis for the prevention and cure of OSAHS complicated with ischemic cerebrovascular diseases.
