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
