          摘   要  目的  探究补阳还五汤(BYHWD)对脑缺血再灌注损伤(CIRI)大鼠线粒体动力学的影响及机制。方法  将CIRI大鼠随机
          分为CIRI组、低剂量BYHWD(L-BYHWD,灌胃3.15 mg/kg)组、高剂量BYHWD(H-BYHWD,灌胃12.60 mg/kg)组、阳性对照(腹
          腔注射 150 mg/kg 银杏叶提取物注射液)组、H-BYHWD+溶剂对照(灌胃 12.60 mg/kg BYHWD+腹腔注射 20 mg/kg 二甲基亚砜)
          组、H-BYHWD+Compound C(灌胃12.60 mg/kg BYHWD+腹腔注射20 mg/kg Compound C)组,每组15只;另取15只大鼠作为假手
          术组。各组大鼠灌胃或腹腔注射相应药液或生理盐水,每日1次,连续4周。末次给药后,检测大鼠脑梗死体积,观察缺血性半暗
          带(IP)区内皮细胞线粒体超微结构,评估IP区线粒体膜电位,检测IP区视神经萎缩蛋白1(OPA1)与分化簇31(CD31)荧光共定位
          面积比,线粒体融合蛋白2(MFN2)、OPA1、线粒体分裂蛋白1(Fis1)蛋白表达水平和AMP活化蛋白激酶(AMPK)/动力相关蛋白1
         (Drp1)通路相关蛋白表达水平。结果  与假手术组比较,CIRI组大鼠脑组织IP区内皮细胞线粒体肿胀且多呈球状,嵴发生断裂且
          空泡现象严重;脑梗死体积百分比、Fis1 蛋白表达水平及 Drp1 磷酸化水平均显著升高(P<0.05),IP 区线粒体膜电位、OPA1 与
          CD31 荧光共定位面积比和 MFN2、OPA1 蛋白表达水平及 AMPK 磷酸化水平均显著降低(P<0.05);与 CIRI 组比较,L-BYHWD
          组、H-BYHWD组、阳性对照组大鼠上述指标均显著改善(P<0.05);与H-BYHWD组、H-BYHWD+溶剂对照组比较,H-BYHWD+
          Compound C组大鼠上述指标均显著逆转(P<0.05);H-BYHWD+溶剂对照组与H-BYHWD组大鼠上述指标的差异均无统计学意
          义(P>0.05)。结论  BYHWD可通过激活AMPK/Drp1通路,改善线粒体动力学紊乱,从而改善CIRI。

          ABSTRACT    OBJECTIVE  To  explore  the  effect  and  mechanism  of  Buyang  huanwu  decoction (BYHWD)  on  mitochondrial
          dynamics in rats with cerebral ischemia-reperfusion injury (CIRI). METHODS CIRI rats were randomly divided into CIRI group,
          low-dose  BYHWD (L-BYHWD,  intragastric  administration  of  3.15  mg/kg  BYHWD)  group,  high-dose  BYHWD (H-BYHWD,
          intragastric administration of 12.60 mg/kg BYHWD) group, positive control (intraperitoneal administration of 150 mg/kg Extract of
          Ginkgo  biloba  leaves  injection)  group,  H-BYHWD+solvent  control (intragastric  administration  of  12.60  mg/kg  BYHWD+
          intraperitoneal  injection  of  20  mg/kg  DMSO)  group  and  H-BYHWD+Compound  C (intragastric  administration  of  12.60  mg/kg
          BYHWD+intraperitoneal  injection  of  20  mg/kg  Compound  C)  group,  with  15  rats  in  each  group.  Additionally,  15  rats  were
          assigned  to  the  sham  operation  group.  All  rats  received  the  corresponding  medications  or  saline  solution  via  intragastric
          administration  or  intraperitoneal  injection  once  daily  for  4  consecutive  weeks.  After  the  last  administration,  the  cerebral  infarct
          volume  of  rats  was  measured;  the  ultrastructure  of  mitochondria  in  endothelial  cells  in  the  ischemic  penumbra (IP)  region  was
          observed;  the  mitochondrial  membrane  potential  was  evaluated;  the  fluorescence  colocalization  area  ratio  of  optic  atrophy  1
         (OPA1)  to  cluster  of  differentiation  31 (CD31)  in  the  IP  region  was  detected;  the  expressions  of  mitofusin  2 (MFN2),  OPA1,
          mitochondrial fission 1 protein (Fis1), and proteins related to the AMP-activated protein kinase (AMPK)/dynamin-related protein 1
         (Drp1)  pathway  in  the  IP  region  were  determined.  RESULTS  Compared  with  the  sham  operation  group,  mitochondria  in
          endothelial cells of the IP region in brain tissue of rats in the CIRI group were swollen, mostly spherical, with fractured cristae and
          severe  vacuolation;  the  percentage  of  cerebral  infarct  volume,  Fis1  expression  level  and  phosphorylation  level  of  Drp1  were
          increased  significantly (P<0.05),  while  mitochondrial  membrane  potential  in  the  IP  region,  fluorescence  colocalization  area  ratio
          of  OPA1  to  CD31,  the  expressions  levels  of  MFN2  and  OPA1,  and  phosphorylation  level  of AMPK  were  significantly  decreased
                                                             (P<0.05).  These  indicators  were  improved  in  the  L-BYHWD
