          摘  要  目的  探究益肺宣肺降浊方通过抑制线粒体分裂对血管性痴呆(VaD)大鼠的干预作用及其潜在机制。方法  采用双侧颈
          总动脉结扎法建立VaD大鼠模型。将实验动物随机分为假手术组(SHAM组)、模型组(MOD组)、益肺宣肺降浊方低剂量组、益肺
          宣肺降浊方高剂量组、盐酸多奈哌齐组(阳性对照),每组9只。干预30 d后,通过Morris水迷宫实验评估大鼠的学习及空间记忆
          能力;苏木精-伊红染色观察海马CA1区组织病理学变化;酶联免疫吸附试验法检测血清中炎症因子[白细胞介素(IL)-1β、IL-4]水平;
          Western blot法检测海马组织中热休克蛋白90(HSP90)/混合谱系激酶结构域样蛋白(MLKL)/动力相关蛋白1(Drp1)信号通路相
          关蛋白、线粒体融合蛋白(MFN1、MFN2)及三磷酸腺苷合成酶5A(ATP5A)的蛋白表达;免疫组化检测磷酸化MLKL(p-MLKL)水
          平;实时荧光定量PCR检测HSP90、MFN1、MFN2、ATP5A 的mRNA表达。结果  与SHAM组比较,MOD组大鼠逃避潜伏期显著
          延长,穿越平台次数显著减少,海马组织呈现典型神经元损伤特征,p-MLKL阳性表达量及血清中IL-1β水平均显著升高,血清中
          IL-4水平显著降低,海马组织中HSP90蛋白及mRNA、p-MLKL/MLKL及p-Drp1(Ser616)/Drp1蛋白表达水平均显著上调,MFN1、
          MFN2、ATP5A蛋白及mRNA和p-Drp1(Ser637)/Drp1蛋白表达水平均显著下调(P<0.05)。经益肺宣肺降浊方干预后,各给药组
          上述指标水平均显著逆转(P<0.05)。结论  益肺宣肺降浊方可能通过调控HSP90/MLKL/Drp1信号通路,抑制线粒体分裂,进而
          维持线粒体动力学平衡,改善线粒体功能,从而起到减轻VaD大鼠的神经元损伤和神经炎症反应的作用。

          ABSTRACT   OBJECTIVE  To  investigate  the  intervention  effect  and  its  potential  mechanism  of Yifei  xuanfei  jiangzhuo  formula
          by  inhibiting  mitochondrial  fission  in  a  vascular  dementia (VaD)  model  rats.  METHODS  VaD  rat  model  was  established  by
          bilateral  common  carotid  artery  ligation.  The  experimental  animals  were  randomly  divided  into  sham  operation  group (SHAM),
          model group (MOD),Yifei xuanfei jiangzhuo formula low-dose group (YFXF-L), Yifei xuanfei jiangzhuo formula high-dose group
         (YFXF-H),  and  Donepezil  hydrochloride  group (positive  control),  with  9  animals  in  each  group. After  30  days  of  intervention,
          the  spatial  learning  memory  ability  was  assessed  by  Morris  water  maze  experiment;  HE  staining  was  used  to  observe
          histopathological  changes  in  CA1  area  of  hippocampus;  ELISA  was  used  to  detect  the  levels  of  serum  inflammatory  factors
          [interleukin-1β (IL-1β)  and  IL-4];  Western  blot  was  used  to  detect  the  expressions  of  heat  shock  protein  90 (HSP90)/mixed
          lineage  kinase  domain-like  protein (MLKL)/dynamin-related  protein  1 (Drp1)  pathway-related  proteins,  mitochondrial  fusion
                                                             proteins  (MFN1,  MFN2) ,  and  adenosine  triphosphate
