Abstract

OBJECTIVE: To explore the mechanism by which Qinghua decoction (清化饮) regulates neuroendocrine inflammation in chronic nonbacterial prostatitis (CNP) model rats and provide an experimental basis for clinical treatment.

METHODS: The rats were randomly divided into six groups: normal control, model, Qianlie Tongyu capsule, low-dose Qinghua decoction, medium-dose Qinghua decoction, and high-dose Qinghua decoction group with six rats in each group. Rats in each group were sacrificed on the 29th day of treatment, and blood and prostate tissues were collected. Serum levels of tumor necrosis factor-alpha and interleukins 1-beta, 6, 8, and 10 (TNF-α and IL-1β, -6, -8, and -10, respectively) were measured using enzyme-linked immunosorbent assay. The pathological changes in the rat prostate tissue in each group were observed under a light microscope. The expression levels of chromogranin A (CgA), nerve growth factor (NGF), and tyrosine kinase A (TrkA) were detected using reverse transcription quantitative polymerase chain reaction. Western blotting was used to detect protein expression of CgA, NGF, and TrkA.

RESULTS: In the model group, the prostate capsule membrane and stroma were significantly dilated with more inflammatory cells infiltrating the stroma and perivessels. TNF-α, IL-1β, -6, and -8, CgA, NGF, and TrkA levels increased, whereas the content of IL-10 decreased, which was statistically significant compared to that in the normal control group (P < 0.05). Prostate tissue cells in the high-dose group were neatly arranged with no obvious inflammatory cell infiltration. When compared with the model group, the high-dose Qinghua decoction group showed a significant improvement in these indices (P < 0.05).

CONCLUSION: Qinghua decoction led to inhibition of pathological changes in the prostate tissue of rats with CNP, regulation of inflammatory cytokine expression, and inhibition in the expression of CgA, NGF, and TrkA. This mechanism may be primarily related to regulation of the CgA/NGF/TrkA signaling pathway mediated by various inflammatory factors.
