          摘  要  目的  基于生长因子受体结合蛋白2(GRB2)/胞外信号调节激酶(ERK)/心磷脂合成酶1(CRLS1)通路,探讨益肺宣肺降
          浊方(YFXF)对血管性痴呆(VAD)模型大鼠的改善作用机制。方法  采用双侧颈总动脉永久性结扎法构建VAD大鼠模型,将48
          只造模成功的大鼠随机分为模型组(生理盐水)、盐酸多奈哌齐组(阳性对照组,0.2 g/kg)及YFXF低、高剂量组(12.18、24.36 g/kg,
          以生药总量计),另设假手术组(生理盐水),每组12只。每天灌胃给药/生理盐水1次,连续30 d。末次给药后,评估大鼠空间认知
          能力,观察其海马组织病理形态学变化,检测其血清中肿瘤坏死因子 α(TNF-α)、白细胞介素 4(IL-4)含量,检测其海马组织中
          GRB2/ERK/CRLS1 通路相关蛋白及 GRB2、CRLS1、NADH 脱氢酶亚基 1(ND1)、Tafazzin(TAZ)、磷脂移位酶 3(PLSCR3) mRNA
          表达水平,并检测其海马组织中腺苷三磷酸(ATP)含量。结果  与假手术组比较,模型组大鼠逃避潜伏期显著延长(P<0.05),穿
          越平台次数显著减少(P<0.05),并可见海马锥体细胞和尼氏小体数量锐减;血清中TNF-α含量显著升高(P<0.05),IL-4含量显
          著降低(P<0.05);海马组织中 GRB2 蛋白表达水平、CRLS1 蛋白表达水平、ERK 蛋白的磷酸化水平以及 GRB2、CRLS1、ND1、
          TAZ、PLSCR3 mRNA相对表达量和ATP含量均显著降低(P<0.05)。与模型组比较,各给药组大鼠海马组织中上述病理改变均有
          所缓解,各定量指标均显著回调(P<0.05)。结论  YFXF可能通过激活GRB2/ERK/CRLS1通路,维护心磷脂稳态,改善线粒体能
          量代谢,从而改善VAD模型大鼠海马神经元损伤。

          ABSTRACT     OBJECTIVE  To  explore  the  improvine  mechanism  of  Yifei  xuanfei  jiangzhuo  formula (YFXF)  on  vascular
          dementia (VAD)  model  rats  based  on  the  growth  factor  receptor-bound  protein  2 (GRB2)/extracellular  signal-regulated  kinase
         (ERK)/cardiolipin  synthase  1 (CRLS1)  pathway.  METHODS  VAD  rat  model  was  established  by  permanent  bilateral  common
          carotid  artery  ligation.  Forty-eight  successfully  modeled  rats  were  randomly  divided  into  the  model  group (normal  saline),
          donepezil  hydrochloride  group (positive  control  group,  0.2  g/kg),  and YFXF  low-  and  high-dose  groups (12.18  and  24.36  g/kg,
          calculated based on the total amount of crude drug), respectively. In addition, a sham operation group (normal saline) was set up.
          There were 12 rats in each group. Daily intragastric administration of drug or normal saline was performed for 30 consecutive days.
          After  the  last  administration,  the  spatial  cognitive  ability  of  the  rats  was  evaluated,  the  pathological  morphology  of  the
          hippocampus was observed, the contents of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) in serum were detected, the
          expression  levels  of  GRB2/ERK/CRLS1  pathway-related  proteins  and  the  mRNA  levels  of  GRB2,  CRLS1,  NADH  dehydrogenase
          subunit  1(ND1),  Tafazzin (TAZ),  phospholipid  scramblase  3(PLSCR3)  and  the  ATP  content  in  hippocampal  tissue  were
          measured.  RESULTS  Compared  with  the  sham  operation  group,  the  escape  latency  of  rats  in  the  model  group  was  significantly
                                                             prolonged (P<0.05),  and  the  number  of  crossing  platform
             Δ 基金项目 国家自然科学基金项目(No.82374387);广西自然科            was  significantly  reduced (P<0.05),  while  the  number  of
