Inclusion criteria
Inclusion criteria: Inclusion criteria: 1. A clinical diagnosis of acute ischemic stroke in the middle cerebral artery (MCA) territory (ACA territory involvement in addition to primary MCA territory stroke is acceptable). A large hemispheric infarction defined as: NCCT/MRI found more than 50% MCA blood supply area or CTP found 2/3 MCA blood supply area involved, and CTA/MRA found internal carotid artery/middle cerebral artery M1 segment occlusion. 2. mRS<2 before symptom onset; 3.15=NIHSS=25; 4. The study drug initiated within 12 hours of symptom onset; 5. 18=Age=85 years; 6. Informed consent was signed by the subject or the legal representative.
Exclusion criteria
Exclusion criteria: Exclusion criteria: 1. Decompressive craniectomy was completed or planned before randomization; 2. Successful endovascular recanalization before initiation of the study drug (reduction of at least 4 points in the NIHSS score, or mRS=1 after thrombolysis; mTICI=2b after thrombectomy); 3. Unable to undergo MRI examination (e.g., due to internal pacemaker or automatic defibrillator); 4. With symptomatic cerebral infarction in both cerebral hemispheres; 5. Presence of clinical signs of brain herniation formation, e.g., unilateral or bilateral pupil dilation and fixation, or loss of brainstem reflexes; 6. CT/MRI indicates PH2 type of cerebral hemorrhage; 7. History of severe kidney disease (e.g., dialysis), or eGFR3 times the upper limit of normal; 9. Pregnancy or breastfeeding; 10.
