This study investigated the pharmacodynamic effects of modified Gexiazhuyu decoction (MGXZYD) and its underlying mechanism in the treatment of chronic salpingitis. The results showed that MGXZYD improved the pathological damage and fibrosis of the oviduct, decreased inflammation, and prevented the progression of chronic salpingitis by inhibiting the p38 MAPK signaling pathway.
OBJECTIVE: To investigate pharmacodynamic effects of modified Gexiazhuyu decoction (MGXZYD) and explore the underlying mechanism in the treatment of chronic salpingitis METHODS: Chronic salpingitis model rats were firstly constructed and the blood was collected to detect the whole blood viscosity and plasma viscosity. Rat oviduct were collected to evaluate the macroscopic damage and the pathological injury and fibrosis of oviduct by hematoxylin-eosin (HE) and Masson staining. Elisa assay was to detect the production interleukin-1 beta (IL-beta) in serum and collagen I (COL-1), matrix metalloprotein 9 (MMP-9), tissue inhibitor of metalloproteinases 1 (TIMP-1) in oviduct tissue. And immunohistochemical staining with MMP-9 and TIMP-1 in oviduct tissue were examined. Western blot was used to detect the expressions of p38 mitogen-activated protein kinases (p38MAPK), phospho-p38MPAK (p-p38MPAK), transforming growth factor-beta 1 (TGF-beta 1) in oviduct. The expression of alpha-smooth muscle actin (alpha-SMA), p-p38MPAK, in oviduct tissue were detected by immunofluorescence method. The mRNA of p-p38MAPK, alpha-SMA, COL-1, MMP-9, TIMP-1 was measured by reverse transcription-polymerase chain reaction. RESULTS: Rats administrated with MGXZYD demonstrated decreased the whole blood viscosity and plasma viscosity. MGXZYD obviously improved the tubal wall thickening, swelling and pelvic adhesion. And HE and Masson staining showed MGXZYD improved the pathological injury and fibrosis of oviduct. The results of MTT assay and flow cytometry indicated that MGXZYD could decreased the NIN-3T3 cells viability and improved the apoptosis. Besides, MGXZYD inhibited the protein and / or mRNA of TGF-beta 1, IL-1 beta, COL-1, alpha-SMA, p-p38MAPK expressions and increased the production of MMP-9/TIMP-1. CONCLUSION: MGXZYD could prevent the progression of chronic salpingitis by inhibited the fibrocyte and inflammation which via inhibited the p38 MAPK signaling pathway. (C) 2022 JTCM.
