Introduction:
The traditional Chinese medicine formula, Bushen Daozhuo Granules (BSDZG), is used to treat chronic non-bacterial prostatitis (CNP) clinically. However, its mechanism of action is unclear. The aim of our study was to determine the effect of BSDZG on CNP and its underlying mechanisms.
Methods:
Male Wistar rats were randomly assigned to control, CNP, and BSDZG groups. CNP was induced using purified prostaglandin solution and Freund's complete adjuvant, after which the BSDZG group received 1.54 g/kg/d of BSDZG for 30 days. Prostate tissues were used to determine apoptosis and inflammatory cytokines. The herb-composition-target network and functional signaling pathways were built using a network pharmacology approach, which was also confirmed in vivo.
Results:
Treatment with BSDZG significantly alleviated the histopathological lesions, inflammation, and apoptosis in the prostate of CNP rats. The herb-composition-target network comprising 42 active compounds and 32 targets of 11 herbs was illustrated, and KEGG pathways analysis identified the Akt and MAPK pathways as related to the effects of BSDZG. Phosphorylation of p38 MAPK, NF-κB, and Bax expression was significantly enhanced and phosphorylated Akt and Bcl-2 levels were decreased in CNP rats, which could be reversed by BSDZG.
Conclusion:
This study presented for the first time that BSDZG effectively alleviated CNP symptoms in rats and elucidated the underlying mechanisms mediated by the Akt and MAPK pathways, providing the theoretical basis for the clinical use and promotion of BSDZG.
