Abstract: Objective The aim of this study was to investigate the clinical efficacy of silymarin and diammonium glycyrrhizinate combination in the treatment of patients with non-alcoholic steatohepatitis(NASH). Methods 97 patients with NASH were encountered in our hospital between October 2022 and June 2024, and were randomly assigned to receive oral diammonium glycyrrhizinate in control (n=48), or to receive diammonium glycyrrhizinate with combination of silymarin in observation (n=49) at base of sport exercise and food guidance for six months. Serum hyaluronic acid (HA), laminin (LN), IV collagen (Ⅳ-C) and III procollagen (PCⅢ) levels were assayed by RIA, and serum interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α) and IL-6 levels were detected by ELIS. Liver stiffness measurements (LSM) and controlled attenuation parameter (CAP) were measured by Fibrotouch. Results By end of six month treatment, serum ALT, AST, GGT levels, and LSM and CAP in the observation group were (49.4±4.2)U/L, (41.1±3.9)U/L, (60.1±5.5)U/L, (7.3±1.2)kPa and (272.3±10.6)dB/m, all significantly lower than [(57.2±6.3)U/L, (49.5±5.2)U/L, (81.5±7.3)U/L, (8.8±2.5)kPa and (289.5±13.8)dB/m, respectively, P<0.05] in the control; serum HA, Ⅳ-C and PCⅢ levels were (62.1±5.7)μg/L, (60.5±6.2)μg/L and (90.3±10.4)μg/L, all much lower than [(73.2±7.4)μg/L, (68.2±8.7)μg/L and (148.5±13.7)μg/L, respectively, P<0.05] in the control; serum IL-10 level was (30.5±7.6)mg/L, much higher than [(25.2±6.3)mg/L, P<0.05], while serum TNF-α and IL-6 levels were (13.1±3.8)mg/L and (13.6±4.0)ng/L, both much lower than [(26.2±5.7)mg/L and (20.1±6.4)ng/L, respectively, P<0.05] in the control group. Conclusion Combination of oral silymarin and diammonium glycyrrhizinate at base of sport and diet guidance in patients with NASH is short-termly efficacious, which needs further clinical investigation.
