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
