Remote Ischemic Postconditioning | Other: Remote Ischemic Conditioning Equipment Procedure: Intravenous blood collection | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 100 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | 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). |
Masking: | Single (Participant) |
Masking Description: | Patients without BAIPC 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' . |

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.

Procedure: Intravenous blood collection
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. The blood samples only use in this trial.

- 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.
- 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.
- 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.
- 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.
