Objective To investigate the effects and mechanism of Zhachong Shisanwei Pills on rats with cerebral ischemia.Methods Totally 75 rats were randomly divided into sham-operation group,model group,positive drug group(Ginaton,21.6 mg/kg),and Zhachong Shisanwei Pills low-,medium-,and high-dosage groups(81,162,324 mg/kg).Each treatment group was given the corresponding drug by gavage for 5 days.On the 6th day,a cerebral ischemia rat model was prepared by suture method.After 24 hours of modeling,the drugs were given in the same manner for 2 days.Neurological function scoring,horizontal beam walking scoring,and grip strength testing were performed on rats.TTC staining was used to detect the cerebral infarction rate,HE staining and Nissl staining were used to observe the morphology of brain tissue.TUNEL staining was used to detect the apoptosis rate of brain tissue cells.Differential genes in the treatment of cerebral ischemia using Zhachong Shisanwei Pills were screened by transcriptomics,and RT-qPCR,immunohistochemistry and Western blot were used to detect differential gene mRNA and protein expression.Results Compared with the sham-operation group,the model group rats showed a decrease in neurological function scores,horizontal beam walking scores,grip strength,an increase in cerebral infarction rate,neuronal nucleus condensation,vacuolar changes,widened intercellular spaces,the number of Nissl bodies reduced,and the apoptosis rate increased(P<0.01,P<0.001);compared with the model group,the Zhachong Shisanwei Pills medium-dosage group showed an increase in neurological function score,horizontal beam walking score,and grip strength in rats,a decrease in cerebral infarction rate,a lower degree of neuronal damage,an increase in the number of Nissl bodies,and a decrease in cell apoptosis rate(P<0.05,P<0.01).Transcriptome and bioinformatics analysis screened the Hippo signaling pathway related to the anti-cerebral ischemia effect of Zhachong Shisanwei Pills.The key genes of this pathway,mammalian sterile line 20 like kinase(MST1)1,Yes related protein(YAP)1,large tumor suppressor kinase(LATS)1,and TEA domain family member(TEAD)1 were detected.The results showed that the expression of MST1 mRNA and protein in brain tissue of model rats significantly increased,while the expressions of YAP1,LATS1,TEAD1 mRNA and protein significantly decreased;Zhachong Shisanwei Pills could down-regulate the expression of MST1 in brain tissue of model rats,and up-regulate the expressions of YAP1,LATS1 and TEAD1.Conclusion Zhachong Shisanwei Pills may exert anti-cerebral ischemia effects through the Hippo signaling pathway.
