The above results showed that the levels of inflammatory index factors IL-1, IL-6, IL-1 β, TNF-α, and IFN-γ in the PCOS-IR model significantly increased, whereas MCDD could reduce IL-1, IL-6, IL-1β, TNF-α, and IFN-γ in a dose-dependent manner. The gene discussed is IL6; the disease is polycystic ovary syndrome.
