Abstract

Objective: This study aims to investigate the efficacy of modified Ginseng Yangrong decoction (GSYRD) promoting angiogenesis after ischemic stroke.

Methods: In an in vivo study, rats that survived surgery were allocated into four groups: the control group and model group were treated with normal saline, the GSYRD group was treated with 18.9 mg/kg of GSYRD daily, and the positive control group was treated with Tongxinluo (TXL) (1 g/kg/d). At the end of the seven-day treatment, the area of cerebral infarction, the expression changes of miRNA-210 and ephrin A3 were determined. In an in vitro study, HUVECs were divided into a normal control serum group (NC group), normal control serum OGD group (Oxygen Glucose Deprivation group) (OGD group), OGD + drug-containing serum group (OGD+GSYRD group), and OGD + drug-containing serum + ES group (Endostatin group) (OGD+GSYRD+ES group). The cells in all groups except the NC group were cultured in a sugar-free DMEM medium under hypoxia for 48 h. Cell proliferation, angiogenic structure formation ability, the expression changes of miRNA-210, ephrin A3, and the HIF/VEGF/Notch signaling pathway-related molecules were determined.

Results: In vivo, GSYRD significantly reduced infarct size (p < .01), the expression of miRNA-210 and ephrin A3 were decreased in the GSYRD group (p < .05). In vitro, the cell proliferation and tube formation ability were significantly increased in the GSYRD group (p < .05), and the expression of miRNA-210 and ephrin A3 was decreased (p < .05). In addition, in the GSYRD group, the expression of the HIF/VEGF/Notch signaling pathway-related molecules was significantly increased (p < .01 or p < .05).

Conclusion: GSYRD promotes cerebral protection following angiogenesis and ischemic brain injury. The specific mechanism was activating the HIF/VEGF/Notch signaling pathway via miRNA-210.
