The hypercholesterolemic rabbit model is established. Hematoxylin and eosin staining, transmission electron microscopy, immunofluorescence, terminal deoxynucleotidyl transferase dUTP nick end labeling staining, immunohistochemistry, Western blot analysis, and reverse transcription-polymerase chain reaction are used to detect the morphological changes in the ENS–ICC–SMC network, the expression of apoptosis-related proteins in the ICC, and to observe the curative effect of SGD after treatment.Results: Compared with the control group, the morphology and the ultrastructure of the SO are destroyed in the model group. In addition, the protein gene product 9.5 (PGP9.5), nitric oxide (NO), the SMCs, and the ICC all significantly decreased while substance P (SP) significantly increased. Compared with the model group, the SO morphology and ultrastructure are repaired in the SGD group. In addition, the PGP9.5, NO, the SMCs, and the ICC significantly increased while SP decreased. In addition, SGD may activate the stem cell factor (SCF)/c-Kit signaling pathway to treat SO dysfunction by up-regulating the expression of c-Kit and SCF. Similarly, this pathway restores SO by up-regulating the expression of Bcl2 and inhibiting cleaved caspase-3, Bax, and the tumor necrosis factor.Conclusion: Shaoyao Gancao decoction can promote the recovery of sphincter of Oddi dysfunction in hypercholesterolemic rabbits by protecting the ENS–ICC–SMC network.Keywords: sphincter of Oddi dysfunction, Shaoyao Gancao Decoction, ENS–ICC–SMC, apoptosis |
