          中的主要药效成分,结合多元统计学方法分析其差异代谢物及相关代谢通路,并基于氧化应激指标进行实验验证。结果  清热活
          血汤可改善MIRI模型大鼠心脏组织病理损伤,显著降低细胞凋亡率(P<0.05)。清热活血汤含药血清包括黄芩苷、琥珀酸、黄芩
          素、隐丹参酮、异阿魏酸、原儿茶醛等20种主要药效成分,可上调L-异亮氨酸、左旋精氨酸、柠檬酸、谷胱甘肽、β-D-葡萄糖、左旋肉
          碱等15种代谢物水平(P<0.05),下调花生四烯酸、3-磷酸-d-甘油磷酸酯、亚油酸、二十二碳六烯酸、磷脂酰胆碱、溶血磷脂酰胆碱
          等14种代谢物水平(P<0.05),主要涉及能量代谢、炎症损伤、氧化应激和自噬等代谢途径。验证实验结果显示,清热活血汤可显

          论  清热活血汤可改善MIRI模型大鼠心脏组织损伤,其药效成分包括黄芩苷、隐丹参酮、异阿魏酸、原儿茶醛等,其作用机制可能
          与改善心肌能量代谢、下调氧化应激水平、抑制炎症浸润有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  pharmacological  components  and  mechanism  of  Qingre  huoxue  decoction  in
          improving  myocardial  ischemia-reperfusion  injury(MIRI).  METHODS  Forty-two  rats  were  randomly  divided  into  sham  operation
          group (normal  saline),  model  group (normal  saline),  Qingre  huoxue  decoction  low-dose,  medium-dose  and  high-dose  groups
         (4.94,  9.88,  19.79  g/kg),Qingre  huoxue  decoction  drug-containing  serum  group (19.79  g/kg)  and  blank  serum  group (normal
          saline),  with  6  rats  in  each  group.  Each  group  was  given  corresponding  drug/normal  saline  intragastrically,  once  a  day,  for
          consecutive  2  weeks.  Twelve  hours  after  last  administration,  except  for  serum  groups,  MIRI  model  was  induced  in  other  groups
         (only threading without ligation in sham operation group). After modeling, cardiac histopathology was observed and apoptosis level
          was detected. UPLC-MS was used to analyze the samples in Qingre huoxue decoction drug-containing serum group and blank serum
          group.  The  main  pharmacological  components  were  screened  with  the  help  of  relevant  databases.  Multivariate  statistical  methods
                                                             were  used  to  analyze  the  differential  metabolites  and  related
