Abstract：Objective To investigate the neuroprotective effect and possible mechanism of Compound Porcine Cerebroside and Ganglio-side Injection (CPCGI) on cerebral ischemia-reperfusion injury in rats. Methods Healthy adult male Sprague-Dawley rats were divided into sham group (n=10), model group (n=10), CPCGI low dosage group (n=10) and high dosage group (n=10), and control group (Ginkgo biloba extract, n=10). All the rats was subjected to middle cerebral artery occlusion (MCAO) for two hours and reperfusion except sham group, and received treatment for fourteen days once reperfusion started. They were tested with modified Neurological Severity Score one, three, seven and fourteen days after MCAO, and adhesive-removal test and beam-walking test fourteen days after MCAO. The expression of Beclin1, PINK1 and Parkin were detected with Western blotting. Results Compared with the model group, the Neurological Severity Score reduced (P<0.05) and the time crossing the beam reduced (P<0.01) in all the medical groups fourteen days after MCAO, and the time removing the adhesive paper reduced in the CPCGI groups (P<0.01). The expression of Beclin1 and Parkin decreased and the PINK1 level increased in the model group (P<0.01), and it was reversed in all the CPCGI groups (P<0.05). Conclusion CPCGI could relieve the cerebral ischemia-re-perfusion injury in rats through the regulation in mitophagy.
