目的:探讨FK866在对乙酰氨基酚(acetaminophen,APAP)诱导小鼠急性肝损伤(acute liver injury,ALI)中的保护作用及机制。方法:24只6周龄的雄性C57BL/6小鼠随机分为对照组、FK866组、APAP组、FK866加APAP组。通过比色法检测血清中丙氨酸转氨酶(alanine aminotransferase,ALT)、天冬氨酸转氨酸(aspartate aminotransferase,AST)活性;HE染色观察肝组织病理学变化;酶联免疫法检测血清中白细胞介素(interleukin,IL)-6、IL-1β、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)含量;Western blot检测尼克酰胺磷酸核糖转移酶(nicotinamide phosphoribosyl-tiansferase,NAMPT)的蛋白表达水平。结果:FK866加APAP组中,ALT和AST分别为(13.969±0.290)、(7.150±0.669) IU/L,较APAP组明显降低(ALT:F=364.709,P=0.000;AST:F=130.398,P=0.000),可见肝脏组织小叶结构较清晰,细胞变性轻微,无明显淤血;炎症因子IL-6、IL-1β、TNF-α检测值分别为(176.333±0.775)、(79.765±1.000)、(147.083±1.000) pg/mL,较APAP组含量明显减少(IL-6:F=207.106,P=0.000;IL-1β:F=165.027,P=0.000;TNF-α:F=118.636,P=0.000);NAMPT蛋白表达水平较APAP组下调。结论:FK866在APAP诱导的ALI中对肝脏具有保护作用,其机制可能与抗炎效应相关。
Objective:To investigate the protective effect of FK866 on acute liver injury(ALI) induced by acetaminophen(APAP) and its mechanism. Methods:Twenty-four male C57BL/6 mice(6-week-old) were randomly divided into the control group,FK866 group,APAP group and FK866+APAP group. The activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) in serum were determined by colorimetric method,the pathological changes of liver by HE(hematoxylin eosin) staining,the levels of tu-mor necrosis factor-α(TNF-α),interleukin-6(IL-6) and interleukin-1β(IL-1β) by ELISA,and the expression of nicotinamide phosphoribosyltransferase(NAMPT) by Western blot. Results:In the FK866+APAP group,the serum activities of ALT and AST were (13.969±0.290) and (7.150±0.669) IU/L respectively and significantly lower than those of the APAP group(ALT:F=364.709,P=0.000;AST:F=130.398,P=0.000). The lobular structure was clear,the cell degeneration was mild,and no obvious congestion was observed in FK866-treated group. Furthermore,the serum levels of IL-6,IL-1β and TNF-α were (176.333±0.775),(79.765±1.000) and (147.083±1.000) pg/mL respectively,indicating the inflammatory factors were notably inhibited by FK866(F=207.106,P=0.000;F=165.027,P=0.000;F=118.636,P=0.000). The expression of NAMPT protein was also down-regulated. Conclusion:FK866 can protect against the acute liver injury induced by APAP,and the anti-inflammatory effects may be involved in it.
