入选标准

  • Ischemic stroke with symptoms of neurological deficits.
  • Aged 18 to 80 years,male or famale.
  • NIH Stroke Scale(NIHSS)scores of 4 to
  • Treatment 4.5 to 6 hours after stroke onset.(Stroke onset time is defined as the last time a patient with no clinical neurological deficit,for patients who wake up with stroke symptoms, consider that stroke occurs when the patient begins to fall asleep).
  • The symptoms of stroke last at least 30 minutes without significant improvement before treatment.
  • CT showed negative or signs of early infarction.
  • Patients and/or their families are willing to participate in this study and agree to sign informed consent.

排除标准

  • Patients with premorbid modified Rankin Scale(mRS) score ≥2
  • CT showed multiple infarctions(low density> 1/3 cerebral hemisphere).
  • Transient ischemic attack.
  • Epileptic seizure when stroke onset.
  • Intracranial tumor, arteriovenous malformation and aneurysm.
  • Iatrogenic Stroke.
  • Thrombectomy is planned.
  • Cardioembolism and atrial fibrillation.
  • Myocardial infarction history within 3 months.
  • Severe cerebral trauma or stroke history within 3 months.
  • Blood pressure is still out of control after aggressive antihypertensive treatment.Uncontrolled blood pressure is defined as systolic blood pressure≥ 180mmHg or diastolic blood pressure≥100mmHg.
  • High density lesions (bleeding) and subarachnoid hemorrhage is revealed by emergency CT examination.
  • Active visceral hemorrhage.
  • Patients with intracerebral hemorrhage history.
  • Patients with diabetic retinopathy history.
  • Puncture in 1 week which can not be oppressed.
  • Major surgery or severe trauma within 2 weeks.
  • Intracranial surgery, intraspinal surgery or solid organ biopsy within 30 days.
  • Heparin treatment within 48 hours (APTT above normal upper limit).
  • Taking anticoagulant drugs orally, and PT >15s or INR >1.
  • High risk of acute hemorrhage include platelet count<10^9/L.
  • Taking thrombin inhibitors or factor Xa inhibitor with abnormal results of sensitive laboratory examination(e.g. APTT, INR, PLT, FIB、TT or appropriate Ⅹ a factor activity test, etc.).
  • Blood glucose < 2.7 mmol/L or > 22.2 mmol/L.
  • Pregnancy, lactating or menstrual women.
  • Patients who have difficulty swallowing and are unable to take medications orally.
  • Clinician thinks patient doesn't fit to participate in the test of other diseases or conditions.
