The poly-ADP ribose polymerase-1/apoptosis-inducing factor pathway may help mediate the protective effect of electroacupuncture on early brain injury after subarachnoid hemorrhage

Subarachnoid hemorrhage (SAH) is a clinically common, acute, critical cerebrovascular disease associated with high mortality. Here, we investigated the effects of electroacupuncture on early brain injury after SAH. We successfully established a Sprague–Dawley rat model of the SAH model, and randomly divided the rats into four groups: sham-operated group, SAH group, positive control group, and electroacupuncture group. Electroacupuncture effectively decreased the number of transferase UTP nick end labeling-positive cells and extent of DNA fragmentation compared with the control, indicating a decrease in apoptosis. Moreover, electroacupuncture decreased the expression of proteins involved in the poly-ADP ribose polymerase-1/apoptosis-inducing factor (PARP-1/AIF) pathway in vivo, and the difference was statistically significant (P
