Abstract：Objective To investigate the mechanism of Jisuishang Formula on cervical myelopathy based on Wnt/β-catenin signaling pathway.Methods Thirty-six adult male SD rats were randomly divided into sham operation group,model group,positive control group(TAK-715,50 mg/kg),Jisuishang Formula low(9.7 g/kg),medium(19.4 g/kg)and high(38.8 g/kg)dose groups,with 6 rats in each group for 4 weeks.The BBB score and inclined plate test were observed at 1,2 and 4 weeks after surgery.HE and Nissl staining were used to observe the histopathology and neuronal condition of the spinal cord.Immunofluorescence was used to detect the protein expres-sions of BDNF,β-catenin,Bax and Bcl-2.Western blot and qRT-PCR were used to detect the expression of Wnt/β-catenin signaling pathway-related proteins and mRNAs.Results Compared with the sham group,the BBB score and inclined plate test score were significantly decreased(P<0.05),the expressions of BDNF,β-catenin and Bcl-2 decreased(P<0.05),the expression of Bax increased(P<0.05),the expressions of β-catenin,LRP-6 and p-GSK-3βdecreased(P<0.05),and the expressions of Caspase-3 and Caspase-9 increased(P<0.05).Compared with the model group,the BBB score and inclined plate test score were significantly increased in the high-dose Jisuishang Formula group(P<0.05),the expressions of BDNF,β-catenin and Bcl-2 increased(P<0.05),the expression of Bax decreased(P<0.05),the expressions of β-catenin,LRP-6 and p-GSK-3βincreased(P<0.05),and the expressions of Caspase-3 and Caspase-9 decreased(P<0.05).Conclusion Jisuishang Formula prescription can inhibit neuronal apoptosis,improve spinal cord microenvironment,and promote neurological function recovery by activating the Wnt/β-catenin signaling pathway.
