Brief Summary

Under hypoxia or high-altitude hypoxia ,it has been found that 2,3-bisphosphoglycerate(2,3-BPG) in erythrocyte increased and facilitated oxygen release to tissues.Remote Ischemic Conditioning(RIC) can also cause hypoxic conditions in local limbs.Thus,we hypothesize that whether RIC could also increase 2,3-BPG in erythrocyte.

Unilateral upper limb 60mmHg RIC

EXPERIMENTAL

RIC is a physical strategy performed by an electric autocontrol device with cuffs placed on unilateral upper limb and inflated to 60 mmHg for 5-min followed by deflation for 5-min, the procedures is performed repeatedly for 5 times.

Device: remote ischemic conditioning

Bilateral upper limb 60mmHg RIC

EXPERIMENTAL

RIC is a physical strategy performed by an electric autocontrol device with cuffs placed on bilateral upper limb and inflated to 60 mmHg for 5-min followed by deflation for 5-min, the procedures is performed repeatedly for 5 times.

Device: remote ischemic conditioning

Unilateral upper limb 200mmHg RIC
