Aims. To explore the effects of Biejiaxiaozheng pills on carbon tetrachloride-induced hepatic fibrosis in rats through the NF-κB/Nrf2 pathway and to explore the possible antifibrotic mechanisms of the drug. Material and Method. A rat model of hepatic fibrosis was established via CCl4 induction. Liver function and antioxidant indices were detected using commercial kits. Hematoxylin-eosin and Masson staining were used to detect pathological changes in hepatic tissues. ELISA was used to measure plasma TNF-α, IL-β, and IL-6 levels. RT-PCR was used to measure changes in TNF-α, IL-β, and IL-6 levels in hepatic tissues. Changes in p65, P-p65, Nrf2, and HO-1 protein expression were detected using western blotting. Results. In rats with hepatic fibrosis, Biejiaxiaozheng pills effectively improved liver function, alleviated fibrosis in hepatic tissues, and significantly reduced collagen accumulation. The pills significantly downregulated inflammatory cytokine expression in hepatic tissues by suppressing p65 phosphorylation and reduced plasma inflammatory cytokine levels to some extent. The pills upregulated Nrf2 and HO-1 expression in hepatic tissues, enhanced antioxidant potential, and upregulated plasma antioxidant levels. Conclusion. Biejiaxiaozheng pills improved hepatic fibrosis symptoms and lesions in rats, likely by inhibiting the NF-κB pathway and promoting the Nrf2 pathway. [ABSTRACT FROM AUTHOR]
