Experimentální: RIC group
The upper limb ischemic conditioning is composed of five cycles of bilateral upper limb ischemia intervened by reperfusion, which is induced by two cuff placed around the upper arms respectively and inflated to 200 mm Hg for 5 minutes followed by 5 minutes of reperfusion by cuff deflation.
This therapy started within 2 hours after r-tPA thrombolytic therapy.
In addition, all participants receive a standard clinical therapy.

V této studii se kondicionační léčba na dálku skládala z pěti cyklů bilaterální ischemie horní končetiny intervenované reperfuzí, která byla vyvolána dvěma manžetami umístěnými kolem horní části paží a nafouknutá na 200 mm Hg po dobu 5 minut, po kterých následovalo 5 minut reperfuze vypuštěním manžety.

The score of Modified Rankin scale score
Časové okno: measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
The Modified Rankin Scale Score (mRS) is the most comprehensive and most widely used primary outcome measurement to assess the neurological functional disability in contemporary acute stroke trials.
The mRS is an ordinal, graded interval scale that assigns patients among 7 global disability levels, which ranges from 0 (no symptom) to 5 (severe disability) and 6 (death).
We will use mRS to evaluate the degree of disability or dependence during daily activities.
The mRS will be assessed by certified study investigator, who is blinded to the treatment assignment, at 90 days postoperation.
The distribution of mRS will be compared between groups

The score of National Institute of Health stroke scale score
Časové okno: measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
National Institute of Health Stroke Scale (NIHSS) is considered as a standardized assessment of neurological functions in the acute phase of stroke, and it is generally used to quantify patient's neurological impairments on 15 items in 11 fields of different neurological status.The score of the scale ranges from 0 to 42.And higher score indicates worse neurological function.

|
The score of Barthel Index(BI)
Časové okno: measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
the BI is used to measure performance in activities of daily living.The score of the scale ranges from 0 to 100.
And lower score indicates worse activities of daily living.
|

|
recurrence of stroke and TIA
Časové okno: changes from baseline(before RIPC) to 90±7 days
|
Stroke recurrence was defined as sudden functional deterioration in neurologic status with a decrease of 4 or more in the NIHSS, or a new stroke lesion on MRI/DWI located at the territory of the affected intracranial arteries.
|
