          摘  要  目的  研究黄芪甲苷(AST)对颅内动脉瘤(IA)大鼠动脉血管内皮组织损伤的影响,并基于核因子κB(NF-κB)/核苷酸结
          合结构域富含亮氨酸重复序列和含热蛋白结构域受体3(NLRP3)信号通路探讨其作用机制。方法  将大鼠分为假手术组(Sham
          组,灌胃并腹腔注射等体积生理盐水)、IA组(灌胃并腹腔注射等体积生理盐水)、AST低剂量组(AST-L组,灌胃40 mg/kg AST)、
          AST 高剂量组(AST-H 组,灌胃 80 mg/kg AST)和 AST-H+HY-N2485 组(灌胃 80 mg/kg 的 AST 并腹腔注射 25 mg/kg 的 NF-κB/
          NLRP3信号通路激活剂HY-N2485)。每天给药1次,连续8周。末次给药后,检测血清中炎症因子[肿瘤坏死因子α、白细胞介素
          18(IL-18)、IL-6]、血管内皮生长因子(VEGF)和内皮肽(ET)水平,观察IA形态,检测血管组织中血管性血友病因子(vWF)、血管细
          胞黏附分子1(VCAM-1)、内皮型一氧化氮合酶(eNOS)和NF-κB/NLRP3信号通路相关蛋白表达水平。结果  与Sham组比较,IA
          组大鼠颅底动脉环有明显突起,动脉血管内皮细胞有明显损伤;血清中炎症因子和VEGF、ET水平,血管组织中vWF、VCAM-1、
          NLRP3蛋白表达水平以及NF-κB蛋白磷酸化水平均显著升高(P<0.05),动脉瘤、内部弹性层破裂均显著增大(P<0.05),eNOS蛋
          白表达水平显著降低(P<0.05);与IA组比较,AST-L组、AST-H组大鼠IA形态及上述指标水平均显著改善(P<0.05),且AST-H
          组较 AST-L 组改善得更明显(P<0.05);HY-N2485 可显著减轻 AST 对 IA 大鼠血管内皮组织损伤的改善作用(P<0.05)。结论
          AST可能通过抑制NF-κB/NLRP3信号通路来抑制炎症因子表达,减轻炎症和血管内皮组织损伤,从而抑制IA形成。

          ABSTRACT   OBJECTIVE  To  investigate  the  effect  of  astragaloside  Ⅳ(AST)  on  the  injury  of  arterial  endothelial  tissue  in  rats
          with  intracranial  aneurysms (IA),  and  to  explore  its  mechanism  of  action  based  on  the  nuclear  factor  κB (NF-κB)/nucleotide-
          binding  domain  leucine-rich  repeat  and  pyrin  domain-containing  protein  3 (NLRP3)  signaling  pathway.  METHODS  Rats  were
          divided  into  Sham  group (intragastric  administration  and  intraperitoneal  injection  of  the  same  volume  of  normal  saline),  IA  group
         (intragastric administration and intraperitoneal injection of the same volume of normal saline), AST low-dose group (AST-L group,
          intragastric administration of 40 mg/kg AST), AST high-dose group (AST-H group, intragastric administration of 80 mg/kg AST),
          AST-H+HY-N2485  group  [intragastric  administration  of  80  mg/kg  AST  and  intraperitoneal  injection  of  25  mg/kg  HY-N2485
         (activator  of  NF-κB/NLRP3  signaling  pathway)]. They  were  given  relevant  medicine,  once  a  day,  for  8  consecutive  weeks. After
          last  medication,  the  levels  of  inflammatory  factors  [serum  tumor  necrosis  factor-α (TNF-α),  interleukin-18 (IL-18),  IL-6]  and
          vascular  endothelial  growth  factor (VEGF)  and  endothelin (ET)  were  detected;  the  morphology  of  IA  was  observed;  the
          expressions  of  von  Willebrand  factor (vWF),  vascular  cell  adhesion  molecule-1 (VCAM-1),  endothelial  nitric  oxide  synthase
         (eNOS),  and  NF- κB/NLRP3  pathway  related  proteins  in  vascular  tissue  were  also  determined.  RESULTS  Compared  with  the
          Sham group, the basilar arterial ring of rats in the IA group had obvious protrusions, and the arterial vascular endothelial cells were
          significantly  damaged.  The  levels  of  inflammatory  factors,  VEGF  and  ET  in  serum,  as  well  as  the  expression  levels  of  vWF,
          VCAM-1 and NLRP3 proteins and the phosphorylation level of NF-κB protein in vascular tissues were increased significantly (P<
          0.05). Aneurysms  and  ruptures  of  the  internal  elastic  layer  were  significantly  increased (P<0.05),  while  the  expression  level  of
          eNOS  protein  was  significantly  decreased (P<0.05).  Compared  with  IA  group,  the  morphology  of  IA  and  the  levels  of  above
          indexes were all improved significantly in AST-L and AST-H groups (P<0.05),and the improvement in the AST-H group was more
          significant  than  that  in  the  AST-L  group (P<0.05);  HY-N2485  could  attenuate  the  improvement  effect  of  AST  on  vascular
          endothelial  tissue  damage  in  IA  rats (P<0.05).  CONCLUSIONS  AST  may  inhibit  the  expression  of  inflammatory  factors,
                                                             alleviate  inflammation  and  vascular  endothelial  tissue  damage
