Effect and mechanism of Salvianolate Lyophilized Injection combined with Xueshuantong Injection on expression of astrocytes and microglia on focal cerebral ischemia-reperfusion injury in rats / 中草药

ABSTRACT

To investigate the effect of Salvianolate Lyophilized Injection (SLI) combined with Xueshuantong Injection (XST) on expression of astrocytes and microglia in cerebral ischemia-reperfusion injury rats. Methods The Wistar rats (250-300 g, male) were randomly divided into six groups: control group, model group, Edaravone group (6 mg/kg, EDI), SLI group (21 mg/kg), XST group (100 mg/kg), and SLI+XST group (1X1S, 21 mg/kg and 100 mg/kg). Rat model of cerebral ischemia-reperfusion injury was created by the middle cerebral artery occlusion (MCAO) by longa method. Drugs were administered tail intravenous injection once a day for 3 d starting from 24 h after reperfusion. The body weight, neurological deficit scores and survival percentage were observed in 3 d after the cerebral ischemia. The expression of GFAP and IBA-1 was determined at 3 d by immunofluorescence. The complicated compound-target-stroke network of SLI and XST was constructed and analyzed by IPA. Results Compared with the model group, 1X1S could significantly improve the neurological dysfunction, increase the body weight, and inhibit the expression of GFAP and IBA-1 in ischemic penumbra (P < 0.01), IPA reveals the molecular mechanism of SLI and XST in the active ingredient and related targets. Conclusion 1X1S has significant protection on cerebral ischemia reperfusion injury in rats, which may be related to the inhibition of the expression of GFAP and IBA-1 and high mobility group box-1 signaling and Interleukine-8 signaling.
