“…Generally speaking, the causes of ischemic stroke could be divided into two categories. 1) Thrombosis formed in the arteries supplying the brain tissue; 2) Blood clots formed in the peripheral vessels were transferred to the cerebral vessels through the blood flow, resulting in embolism. , Since then, the blood supply to the brain had been reduced or interrupted, resulting in an insufficient supply of oxygen, glucose, and other essential nutrients to the brain, resulting in damage to brain cells and loss of function. , Damaged cells released a variety of molecular substances, such as cytokines, chemokines, injury-related factors, pro-inflammatory factors, etc., which promoted the polarization of activated microglia, resulting in further damage. , In addition, oxidative stress, glutamate excitability, nitrite stress, and cell edema also played an important role in aggravating tissue injury . After the duration of ischemia was too long, due to the role of anaerobic glycolysis, the formation and accumulation of local lactic acid led to edema and neuronal tissue damage .…”
