ABSTRACT
<p><b>OBJECTIVE</b>To investigate the protective effects of polydatin on sepsis-induced acute liver injury (ALI) in mice, and to preliminarily study its mechanisms.</p><p><b>METHODS</b>The sepsis model was established using cecal ligation and puncture (CLP).A sham-operation control group was also set up. Polydatin (50, 100, and 300 mg/kg, respectively) was administrated to mice 1 h before CLP. The survival and liver injury were evaluated subsequently per 6 h after CLP. The survived mice were scarified 24 h later. The serum and the liver tissue sample were collected. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected by colorimetric method. The content of tumor necrosis factor-alpha (TNF-alpha) was assayed by ELISA. The cyclooxygenase-2 (COX-2) expression in the liver tissue was detected by Western blot. The pathological changes of the hepatic tissue were analyzed by hematoxylin and eosin stain.</p><p><b>RESULTS</b>The mortality of mice reached as high as 50% at 24 h after CLP. The biochemical indices and the pathological changes of the liver tissue showed obvious lesion. The success rate of modeling was 90%. Compared with the sham-operation control group, the serum ALT,AST activity, the TNF-alpha content, and the hepatic COX-2 protein expression markedly increased in the CLP group (P < 0.01). Polydatin improved the sepsis-induced mortality dose-dependently, inhibited increased ALT, AST activity and TNF-alpha, decreased the hepatic COX-2 protein expression, and attenuated the pathological injury of the liver (P < 0.05).</p><p><b>CONCLUSION</b>Polydatin could effectively protect sepsis-induced ALI, which might be achieved possibly through inhibiting serum TNF-alpha production and hepatic COX-2 expression.</p>
