          摘  要  目的  探究天麻芎苓止眩片对大鼠血管内皮细胞自噬的影响及潜在机制。方法  将大鼠主动脉内皮细胞(RAECs)分为正
          常组、模型组、空白血清组、中药含药血清组、自噬阻断剂组、自噬激动剂组、中药联合自噬激动剂组。除正常组外,其余各组分别
          加入10 μg/mL脂多糖干预24 h建立RAECs炎症损伤模型。空白血清组加入10%空白血清,中药含药血清组加入10%天麻芎苓
          止眩片含药血清,自噬阻断剂组加入 20 μmol/L PD98059,自噬激动剂组加入 50 μmol/L Honokiol,中药联合自噬激动剂组加入
          10%天麻芎苓止眩片含药血清和50 μmol/L Honokiol。观察各组RAECs形态学特征,检测各组细胞活力、上清液中内皮素1(ET-
          1)和一氧化氮(NO)水平、线粒体活性氧水平、线粒体膜电位,以及PTEN诱导激酶1(PINK1)、E3泛素连接酶Parkin、选择性自噬
          接头蛋白62(p62)、微管相关蛋白1轻链3(LC3)的蛋白表达。结果  与模型组比较,自噬阻断剂组和中药含药血清组的ET-1水平、
          线粒体活性氧水平及PINK1、Parkin、LC3蛋白的相对表达量均显著降低或下调(P<0.05或P<0.01),细胞存活率(仅自噬阻断剂
          组)、NO水平、线粒体膜电位、p62蛋白的相对表达量均显著升高或上调(P<0.05或P<0.01),RAECs病理损伤改善明显,细胞数
          量显著增加,恢复典型的铺路石样特点;自噬激动剂组的ET-1水平、线粒体活性氧水平及Parkin和LC3蛋白的相对表达量均显著
          升高或上调(P<0.05或P<0.01),细胞存活率显著降低(P<0.05),病理损伤加重。与自噬激动剂组比较,中药联合自噬激动剂组
          细胞存活率、p62蛋白相对表达量均显著升高或上调(P<0.05或P<0.01),ET-1水平及PINK1、Parkin、LC3蛋白的相对表量均显著
          下调(P<0.01),RAECs形态结构受损被一定程度逆转。结论  天麻芎苓止眩片可通过调控线粒体自噬来保护血管内皮功能,其作用
          机制可能与调控PINK1/Parkin信号通路、抑制线粒体自噬有关。

          ABSTRACT   OBJECTIVE  To  explore  the  effects  of  Tianma  xiongling  zhixuan  tablet  on  autophagy  in  vascular  endothelial  cells
          of rats and its potential mechanism. METHODS  The rat aortic endothelial cells (RAECs) were divided into normal group, model
          group,  blank  serum  group,  traditional  Chinese  medicine (TCM)  medicated  serum  group,  autophagy  blocker  group,  autophagy
          agonist  group,  and  TCM  combined  with  autophagy  agonist  group.  Except  for  normal  group,  other  groups  were  given  10  μg/mL
          lipopolysaccharide  for  24  hours  to  induce  RAECs  inflammation  injury  model.  Blank  serum  group  was  treated  with  10%  blank
          serum;  TCM  medicated  serum  group  received  10%  medicated  serum  derived  from  Tianma  xiongling  zhixuan  tablet;  autophagy
          blocker  group  was  treated  with  20  μmol/L  of  PD98059;  autophagy  agonist  group  was  administered  50  μmol/L  Honokiol.  Lastly,
          the  TCM  combined  with  autophagy  agonist  group  was  given  both  10%  medicated  serum  derived  from  Tianma  xiongling  zhixuan
          tablet and 50 μmol/L Honokiol. The morphological characteristics of RAECs in each group were observed. The cell viability of each
          group,  the  contents  of  endothelin-1 (ET-1)  and  nitric  oxide (NO),  mitochondrial  reactive  oxygen  species,   mitochondrial
          membrane potential, and the expression levels of PTEN-induced kinase 1 (PINK1), Parkin, ubiquitin-binding protein (p62), and
          microtubule-associated  protein  1  light  chain  3 (LC3)  were  detected.  RESULTS  Compared  with  model  group,  the  levels  of  ET-1,
                                                             mitochondrial  reactive  oxygen  species,  and  the  relative
