Stroke is one of the main severe disease of public health importance. Increasing evidence suggests that inflammatory mechanisms plays a significant role in stroke. So, immune targets are supposed to be an effective one. The sphingosine-1-phosphate receptor regulator Fingolimod(FTY720)is an effective immunology modulator which has been widely used in autoimmune disease and has been testified effective on stoke animal models.

This study will enroll 87 stroke patients who have been diagnosed with stroke and meet the inclusion criteria.

After successfully meeting initial screening criteria, investigators will contact the family, explain the study, and send a consent form for their review.

After that, patients will be given 0.5mg/day oral fingolimod over a course of 3 consecutive days , then investigators will make a neurofunctional assessment before and 7days, 30 days and 90days after oral fingolimod. And Magnetic Resonance of the brain before, 7days, 14days and 90days after oral fingolimod. Furthermore 5ml intravenous blood for flow cytometry is also taken before and 1day,3days,7days after fingolimod use.

Inclusion Criteria:

• Age 18-80 years
• Clinical presentation of spontaneous intracerebral hemorrhage/ischemic stroke
• MRI/MRA scan compatible with spontaneous intracerebral hemorrhage/ ischemic stroke
• Time to fty720 treatment< 72 h from symptom onset
• Glasgow Coma Score >6 on initial presentation or improvement to a Glasgow Coma Score >6 within the time frame for enrollment.
• Primary supratentorial ICH of ≥5cc and <30cc
• TOAST: Large-artery atherosclerosis

Exclusion Criteria:

• Patients who will undergo surgical evacuation of intracerebral hemorrhage
• Inability to undergo neuroimaging with Magnetic Resonance
• Glasgow Coma Score < 6.
• Baseline modified Rankin Scale score >1
