Brief Summary:
Remote ischemic postconditioning (RIPC) is suggested to protect the cerebral cell against ischemia in various settings. However, the effect of RIPC in patients with acute ischemic stroke who undergo thrombolysis has yet to be examined. In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of nerve function deficient in response to thrombolysis. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis. The primary endpoint was the recovery of nerve function deficient assessed by National Institutes of Health Stroke Scale(NIHSS), Activities of Daily Living(ADL), Modified Rankin Scale(mRS), CT cerebral perfusion imaging (CTP) and CT angiography(CTA). Secondary endpoints included the following: angiogenesis assessed by the level of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF).

Arm Intervention/treatment
Experimental: RIPC
Remote ischemic postconditioning(RIPC):Patients in the RIPC group not only receive foundational treatment but also have five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm using a RIPC device (IPC-906X; Beijing Renqiao Institute of Neuroscience, Beijing, China) after thrombolysis while in-hospital.
Device: RIPC device (IPC-906X)
Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis.
Other Name: Thrombolysis

No Intervention: Blank control group(BC)
Blank control group:Patients in the BC group only receive foundational treatment, including free radical elimination in the acute stage, blood pressure and blood glucose stabilization, and antiplatelet (aspirin, 100-300 mg/d) and lipid-lowering (atorvastatin, 20 mg/d) drugs,throughout the 14 days in-hospital period without remote ischemic postconditioning after thrombolysis.

Primary Outcome Measures :
  1. the percentage of patients with a favorable outcome, defined as a score of 0 or 1 on the modified Rankin scale (mRS). [ Time Frame: Day 90 ]

Secondary Outcome Measures :
  1. the percentage of functional recovery at discharge and at day 90, as measured by the NIHSS, the Barthel index (BI) and the mRS [ Time Frame: Day 90 and at discharge(up to day 14) ]
    we measured how many patients achieved a score of 0 or 1 for the NIHSS, 95 for the BI, and 0 - 2 for the mRS.

  2. Plasma biomarker concentrations [ Time Frame: Day 1 and at discharge ( up to day 14) ]
    Venous blood was drawn before the administration of IV tPA and at the end of hospitalization to determine the effect of repeated RIPC on anti-inflammatory (S100-β), vascular (VEGF, bFGF), anti-edema (MMP9), anti-oxidants (OH1) and other pathways (BDNF, HSP).

Other Outcome Measures:
  1. mortality rate [ Time Frame: up to 3 months. ]
    three-month mortality rate

  2. the rate of symptomatic hemorrhagic transformation [ Time Frame: up to 36 hours ]
    Defined by European Cooperative Acute Stroke Study III classification

  3. Early neurological deterioration [ Time Frame: up to 24 hours after IV tPA ]
  4. The tolerance index [ Time Frame: up to 14 days ]
    the proportion of patients that could complete every RIPC treatment session during his/her hospital stay.
