BACKGROUND: Intracerebral hemorrhage (ICH) is a significant global disease with high mortality and disability. As of now, there is no effective therapy available. Oxidative stress and neuronal apoptosis play essential roles in ICH, determining neuronal survival. In our preliminary studies, we found that Baihui-penetrating-Qubin acupuncture could improve neurological deficits and neuropathological damage in the perihematomal area in ICH rats. The SIRT1/FOXO1 signaling pathway has been reported to mediate antioxidant and anti-neuronal apoptosis. This study aimed to investigate the effects of Baihui-penetrating-Qubin acupuncture on oxidative stress and neuronal apoptosis after ICH and the role of SIRT1/FOXO1 in acupuncture's neuroprotection. METHODS: ICH rat models were established by autologous tail blood (50 µL) infusion into the caudate nucleus. EX527, SIRT1-specific inhibitor was intraperitoneally administered 3 days before ICH. Baihui-penetrating-Qubin acupuncture treatment was performed once a day for 30 min after ICH. Neurological deficits were evaluated using the modified neurological severity score (mNSS). Brain edema was evaluated using brain water content. HE staining and Nissl staining were used to evaluate neuropathological damage in the perihematomal area. Terminal deoxynucleotidyl transferase dUTP nick end labeling was used to quantify neuronal apoptosis. Specific kits were used to detect the levels of SOD, CAT, GSH-Px in the brain. The oxidative DNA damage was ev...
