ABSTRACT

Aim To investigate the effect of salvianolate syophilized injection on brain tissue gene expression profiles in stroke of diabetic rats.Methods T1DM was induced in adult male Wistar rats by injecting streptozotocin.T1DM rats were then subjected to 90 minutes of middle cerebral artery occlusion(MCAO).The rats were randomly assigned to sham group(DM+Sham),ischemia-reperfusion group(DM+ MCAO/R),edaravone group(6 mg·kg-1,ED)and salvianolate lyophilized injection treatment group(5.25,10.5,21 mg·kg-1,SLI)with 13 rats in each group.Drugs were administered by tail vein injection 3 hours after MCAO/R,daily and lasting for 14 days.Infarct volume and gene expression in the brain tissue were detected by TTC staining and the gene chip technique.Results Compared with DM+Sham group,67 differential expressed genes were detected in the DM+MCAO/R group,among which 41 genes were up-regulated and 26 genes were down-regulated.Compared with DM+MCAO/R group,59 differential expressed genes were detected in the SLI(21 mg·kg-1)group,among which 45 genes were up-regulated and 14 genes were down-regulated.Hierarchical cluster results suggested that a number of genes were significantly changed in T1DM rats,such as Ly6i,Pax7 and Irx2.Effects of SLI on the stroke in T1DM rats were majorly related to coagulation and hemostasis system,inflammatory cytokines,oxidative stress,substance metabolism,angiogenesis and signal transduction.Conclusion Salvianolate lyophilized injection protects against focal cerebral ischemia/reperfusion injury in type 1 diabetic rats through regulation of the coagulation and hemostasis system,inflammatory cytokines,oxidative stress,substance metabolism,angiogenesis and signal transduction.
