The Influence of Bilateral Arm Ischemic Postconditioning on Clinical Prognosis and Outcome in Patients With Acute Ischemic Stroke(BAIPC)
Influence of bilateral arm ischemic postconditioning (BAIPC)on the injury and protective blood markers and the clinical prognosis and outcome in patients with acute ischemic stroke
Study Overview
Status
Unknown
Conditions
Intervention / Treatment
Detailed Description
In this study, we explore the influence of bilateral arm ischemic postconditioning (BAIPC) to patients with anterior circulation acute ischemic stroke.
Patients with anterior circulation acute ischemic stroke are enrolled and divided into control group and experimental group.
Patients in experimental group are administrated with BAIPC within 3 days from the occurrence of stroke.
The National Institute of Health stroke scale (NIHSS) will be evaluated at different time point to analyze the influence of BAIPC to acute ischemic patients.
The level of IL-4, IL-6,TNF-α as well as the frequency of different sub-populations T cells in the blood at different time point will be detected to explore the possible mechanism of BAIPC protective function.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: ACI with BAIPC
Beside of routine treatment for Anterior circulation infarction(ACI) patients, BAIPC group patients are admistrated by 5 cycles extremities ischemia (5-minute blood-pressure cuff inflation up to 50 mmHg higher than baseline, followed by 5-minute cuff deflation).
All subjects will take BAIPC for 1 week using 'Remote Ischemic Conditioning Equipment' .Intravenous blood collection with anticoagulant and 5ml total blood will be administered at 0d, 1d and 7-10d respectively.
The blood samples will be stored for laboratory assay.
The blood samples only use in this trial.
|
Nurses will collect 5 ml intravenous blood with anticoagulant and 5ml total blood at 0d, 1d and 7-10d respectively.
The blood samples will be stored for laboratory assay.
The blood samples only use in this trial.

Sham Comparator: ACI without BAIPC
ACI patients in this group only recieve routine treatment for ischemic stroke and are admistrated by 5 cycles extremities ischemia (5-minute blood-pressure cuff inflation using pressure 0 mmHg , followed by 5-minute cuff deflation).
All subjects will take BAIPC for 1 week using 'Remote Ischemic Conditioning Equipment' .Intravenous blood collection with anticoagulant and 5ml total blood will be administered at 0d, 1d and 7-10d respectively.
The blood samples will be stored for laboratory assay.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes of pheripheral serum cytokines
Time Frame: 0d, 1d and 7-10d
|
We evaluate the changes of the concentration of serum cytokine (IL-4, IL-6, TNF, et.al) at 0d, 1d, 7-10d respectively to demonstrate whether acute stroke would depress the immune state of patients and wether BAIPC can influence the immune state of patients suffering acute stroke.
|
0d, 1d and 7-10d
|
Changes of pheripheral immune cells
Time Frame: 0d, 1d and 7-10d
|
We evaluate the frequency of pheripheral immune cells (Th1, Th2, Th17 and Treg cells) at 0d, 1d and 7-10d to demonstrate whether acute stroke would depress the immune state of patients and wether BAIPC can influence the immune state of patients suffering acute stroke.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes of National Institute of Health Stroke scale (NIHSS)
Time Frame: Before BAIPC and after BAIPC for one week
|
We evaluate patients NIHSS before BAIPC and after BAIPC for one week to see wether BAIPC could improve the short term prognosis of patient.Scoring Definitions include level of consciousness, visual field, facial palsy,limb motor,sensory ,language,and dysarthria .The NIHSS captures both motor and non-motor impairments of stroke, and provides a good overview of people's deficits.NIHSS ranges from 0 to 42, with high scores corresponding to increased severity of stroke with worse prognosis.
|
Before BAIPC and after BAIPC for one week
|
Relapse of ischemic stroke
Time Frame: one year after patients' first stroke
|
We observe the relapse of ischemic stroke after one yearto see wether BAIPC could improve the long term prognosis of patient.
|
one year after patients' first stroke
