Ethnopharmacological Relevance. The Hugan Qingzhi tablet (HQT) is a traditional Chinese medicine used for treating NAFLD (nonalcoholic fatty liver disease). The present study evaluated the anti-inflammatory effects of HQT in rats with NAFLD. Materials and Methods. HQT was administered daily to the NAFLD experimental groups. Biochemical markers, histopathological data, and oxidative stress/antioxidant biomarkers were determined. Proinflammatory cytokines interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α), and interleukin-6 (IL-6) were detected by enzyme-linked immunoassay. Expressions of silent information regulator 1 (SIRT1) and acetylated-nuclear-factor kappaB-p65 (Ac-NF-κB-p65) were performed by western blotting. Results. At high and moderate doses, HQT was highly effective in decreasing serum alanine aminotransferase (P < 0.01), aspartate aminotransferase (P < 0.01), hepatic total cholesterol (P < 0.01), triglycerides (P < 0.01), and free fatty acid levels (P < 0.01). Moreover, high and moderate doses of HQT reduced hepatic levels of the proinflammatory cytokines TNF-α (P < 0.01), IL-1β (P < 0.01), and IL-6 (P < 0.01), enhanced SIRT1 expression, and depressed Ac-NF-κB-p65 expression at protein level. Conclusions. In our NAFLD rat model, HQT exerted substantial anti-inflammatory and antioxidant activities, possibly involving the regulation of SIRT1 and Ac-NF-κB-p65 expression.
