Sperimentale: 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.

In questo studio, il trattamento di condizionamento ischemico remoto era composto da cinque cicli di ischemia bilaterale dell'arto superiore intervenuta da riperfusione, che è stata indotta da due polsini posizionati rispettivamente attorno alla parte superiore delle braccia e gonfiati a 200 mm Hg per 5 minuti seguiti da 5 minuti di riperfusione mediante sgonfiaggio del bracciale.

The score of Modified Rankin scale score
Lasso di tempo: 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
Lasso di tempo: 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.
|
measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
|
The score of Barthel Index(BI)
Lasso di tempo: 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.
|
measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
|
recurrence of stroke and TIA
Lasso di tempo: 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.
|
changes from baseline(before RIPC) to 90±7 days
|
|
death and any other adverse events
Lasso di tempo: changes from baseline(before RIPC) to 90±7 days
|
The investigator will record the number.

any ICH
Lasso di tempo: changes from baseline(before RIPC) to 90±7 days
|
Head computed tomography or magnetic reasoning imaging (MRI) scan will be performed to confirm intracerebral hemorrhage, and the imaging will be evaluated by two independent neuroradiologists who are blinded to the study assignment.
|

The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain.
The score from 0-10. the higher
|
during 90 days
|
|
