          摘   要  目的  基于血清代谢组学技术研究佛手柑内酯(BP)治疗肝纤维化的作用及机制。方法  将 40 只小鼠分为正常对照组
         (0.5%羧甲基纤维素钠溶液)、模型组(0.5%羧甲基纤维素钠溶液)和BP低、高剂量组(50、100 mg/kg),每组10只。除正常对照组
          外其余3组小鼠均采用四氯化碳诱导肝纤维化模型。同时,各组小鼠灌胃相应药物/溶剂,每日1次,连续8周。末次给药后,检测
          小鼠血清中丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)水平,观察小鼠肝组织病理形态学变化,检测小鼠肝组织中α-平滑肌肌
          动蛋白(α-SMA)、Ⅰ型胶原蛋白(Collagen Ⅰ)表达,同时对小鼠血清进行代谢组学分析。结果  与模型组比较,BP低、高剂量组小
          鼠血清中ALT、AST水平和肝组织中α-SMA、Collagen Ⅰ蛋白表达水平均显著降低(P<0.05),肝组织的纤维化程度显著改善。代
          谢组学结果显示,BP高剂量组和模型组共有175个血清差异代谢物,其中18个物质上调、157个物质下调,涉及的主要代谢途径有
          嘧啶代谢、丁酸盐代谢、脂肪酸合成、酪氨酸代谢、β-丙氨酸代谢、烟酸和烟酰胺代谢以及谷胱甘肽代谢等。结论  BP可能通过调
          节肝纤维化小鼠血清中嘧啶代谢、丁酸盐代谢和谷胱甘肽代谢等途径达到治疗肝纤维化的作用。

          ABSTRACT    OBJECTIVE To study the effects of bergapten in the treatment of liver fibrosis and its mechanism based on serum
          metabolomics.  METHODS  Forty  mice  were  divided  into  normal  control  group (0.5%  carboxymethyl  cellulose  sodium  solution),
          model group (0.5% carboxymethyl cellulose sodium solution), and BP low-dose and high-dose groups (50, 100 mg/kg), with 10
          mice in each group. Except for the normal control group, the other three groups were all treated with carbon tetrachloride to induce
          liver fibrosis model; they were given relevant medicine/solution intragastrically, once a day, for consecutive 8 weeks. After the last
          medication, the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum were detected, and liver
          pathological  changes  were  observed;  the  expressions  of  α-smooth  muscle  actin (α-SMA)  and  Collagen  Ⅰ  were  detected  in  liver
          tissue; the serum of the mice was collected for metabolomics analysis. RESULTS Compared with the model group, serum levels of
          ALT and AST and protein expressions of α-SMA and Collagen Ⅰ in liver tissue were decreased significantly in BP high-dose and
          low-dose  groups (P<0.05),  while  liver  fibrosis  was  improved  significantly.  Meanwhile,  metabolomics  analyses  showed  that  there
          were  a  total  of  175  serum  differential  metabolites  in  the  BP  high-dose  group  and  model  group,  of  which  18  substances  were
          upregulated  and  157  substances  were  downregulated;  the  main  metabolic  pathways  involved  in  bergapten  intervention  were
          pyrimidine metabolism, butanoate metabolism, fatty acid synthesis, tyrosine metabolism, β-alanine metabolism, nicotinic acid and
          nicotinamide  metabolism,  glutathione  metabolism,  etc.  CONCLUSIONS  BP  is  effective  in  the  treatment  of  liver  fibrosis  by
          regulating pyrimidine metabolism, butanoate metabolism, glutathione metabolism and so on in rats with liver fibrosis.
