  • 摘要:The administration of recombinant human soluble thrombomodulin (rhsTM) significantly improves liver inflammation and increases the survival rate of patients with acute liver failure (ALF). However, rhsTM is dose-dependently correlated to the risk of bleeding. Recently, ultrasound (US) was found to enhance the effect of various drugs. Thus, the present study aimed to determine the enhancement effect of US irradiation on rhsTM in ALF. rhsTM (1 mg/kg) and US (1 MHz, 0.3 W/cm 2 ) were irradiated to the liver of lipopolysaccharide/D-galactosamine-induced ALF mice model. The post-treatment aspartate aminotransferase, alanine aminotransferase, and high-mobility group box 1 levels were significantly lower in the rhsTM + US group than in the rhsTM alone group. Histopathological findings revealed significantly reduced liver injury and apoptosis in the rhsTM + US group. By contrast, US irradiation had no effect on rhsTM and TNF-α concentration in the liver tissue. In conclusion, US irradiation enhanced the effect of rhsTM in the ALF mice model. However, further studies must be conducted to determine the exact mechanism of such enhancement effect.
