Peginterferon-α treatment exhibits low rates of the serological conversion rate of hepatitis B e antigen (HBeAg) and the negative conversion rate of hepatitis B virus (HBV) DNA, with significant myelosuppression leading to treatment discontinuation in some patients. Traditional Chinese medicine (TCM) may ameliorate liver inflammation and modulate immune responses. This study aims to investigate the efficacy of combining TCM with pegylated-interferon (PEG-IFN) α-2b and its impact on myelosuppression adverse effects.

This study included 117 HBeAg-positive chronic hepatitis B (CHB) patients who started initial antiviral therapy at Xiamen Hospital of TCM between June 2018 and January 2023. According to the treatment regimen, patients were divided into the observation group (n = 56, receiving PEG-IFN α-2b combined with Licorice 15 g, Angelica sinensis 20 g, Poria 20 g, Paeonia lactiflora 20 g, Rhizoma Atractylodis Macrocephalae 20 g, Radix Bupleurum Chinense 20 g, Mentha piperita 3 g, Ginger three slices for more than six months) and the control group (n = 61, receiving PEG-IFN α-2b alone). This study retrospectively analyzed etiological indicators, liver biochemical indicators, and blood routine tests before and after treatment.

After 24 and 48 weeks of treatment, the observation group demonstrated significantly superior outcomes to the control group in quantitative reduction of hepatitis B surface antigen, the serological conversion rate of HBeAg, and the reduction in HBV DNA quantification (P < 0.05). By week 48, the HBV DNA negative conversion rate in the observation group (46.67%) was significantly higher than that in the control group (26.67%) (P < 0.05). Regarding safety, the incidence of myelosuppression in the observation group was significantly lower than that in the control group at both 24 and 48 weeks of treatment (P < 0.05)

Real-world findings demonstrate that adjunctive TCM significantly enhances the antiviral efficacy of peginterferon α-2b in HBeAg-positive CHB patients while concurrently mitigating treatment-limiting myelosuppression. This combination strategy may represent a clinically valuable approach to optimizing interferon-based therapy for CHB.

Metabolic dysfunction-associated steatohepatitis (MASH) represents a critical step in the progression from simple fatty liver disease to more severe conditions such as cirrhosis and hepatocellular carcinoma, and it remains difficult to treat. Arctigenin (ATG), a monomer of Fructus Arctii, exhibits anti-inflammatory activity. Therefore, we aimed to examine its potential protective role against MASH and explore the underlying mechanisms.

Male C57BL/6 mice were divided into four groups: control, MASH, low-dose ATG (30 mg/kg/day), and high-dose ATG (120 mg/kg/day). MASH was induced through a choline-deficient, L-amino acid-defined high-fat diet for eight weeks, with concurrent preventive ATG administration. Liver injury, lipid metabolism, inflammation, oxidative stress, and fibrosis were assessed. Network pharmacology was employed to identify the potential protective mechanisms of ATG. Key factors were evaluated in vitro to verify the ATG targets.

ATG administration prevented the progression of MASH in a dose-dependent manner. High-dose ATG significantly reduced hepatic macrophage and neutrophil infiltration, serum enzyme levels, and lipid peroxidation, while enhancing antioxidant enzyme activity. Mechanistic network pharmacology identified modulation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome as the central pathway underlying ATG’s bioactivity. Functional analyses in lipopolysaccharide-stimulated RAW264.7 cells confirmed that ATG inhibited NLRP3 expression, pyroptosis-related protein cleavage (hereinafter referred to as GSDMD-N), and pro-inflammatory chemokine production in a concentration-dependent manner. Notably, ATG disrupted NLRP3/GSDMD-N axis activity in macrophages without causing cellular toxicity.

ATG may inhibit the inflammatory cascade primarily by targeting macrophage NLRP3 inflammasomes, thereby preventing the progression of MASH.
