Objective: To explore the effects and molecular mechanisms of the combination between total Astragalus extract (TAE) and total Panax notoginseng saponins (TPNS) against cerebral ischemiareperfusion injury. Methods: C57BL/6 mice were randomly divided into sham-operated group, model group, TAE (110 mg/kg) group, TPNS (115 mg/kg) group, TAE-TPNS combination group and Edaravone (4 mg/kg) group, treated for 4 days, then, cerebral ischemia-reperfusion injury was established by bilateral common carotid artery (CCA) ligation for 20 min followed by reperfusion for 1 and 24 h. Results: TPNS could increa...
