Electroacupuncture attenuates brain injury through α7 nicotinic acetylcholine receptor-mediated suppression of neuroinflammation in a rat model of asphyxial cardiac arrest.

We determined whether electroacupuncture (EA) ameliorated brain injury following asphyxial cardiac arrest (CA) and evaluated the role of the α7 nicotinic acetylcholine receptor (α7nAChR)-mediated anti-inflammatory pathway. In CA-induced rats, EA reduced brain injury and promoted behavioral recovery. Morris water maze escape latency time reduced after Baihui (GV20) and Shuigou (DU26) stimulation.
