          因子κB(NF-κB)、NOD样受体热蛋白结构域相关蛋白3(NLRP3)、胱天蛋白酶1(Caspase-1)、IL-1β、IL-18 mRNA表达水平和IκB、
          NF-κB、NLRP3、凋亡相关斑点样蛋白质(ASC)、Caspase-1、消皮素D(GSDMD)、IL-1β、IL-18蛋白表达水平,并观察主动脉组织形
          态学变化。结果  与模型组比较,化瘀祛痰方组及瑞舒伐他汀组小鼠血清中 TC、TG、LDL-C、IL-1β、IL-18 水平,主动脉组织中
          IκB、NF-κB、NLRP3、Caspase-1、IL-1β、IL-18 mRNA 表达水平以及 IκB、NF-κB、NLRP3、ASC、Caspase-1、GSDMD、IL-1β、IL-18 蛋

          ABSTRACT   OBJECTIVE  To  explore  the  effects  and  mechanism  of  Huayu  qutan  formula  on  atherosclerosis (AS)  in ApoE -/-
          mice.  METHODS  Thirty  ApoE -/-   mice  were  randomly  divided  into  model  group,  Huayu  qutan  formula  group  [20  g/(kg·d)],
          rosuvastatin  group  [1.55  mg/(kg·d)],  with  10  mice  in  each  group.  Another  10  C57BL/6J  mice  were  selected  as  normal  control
          group. ApoE -/-   mice  were  given  high-lipid  diet  for  12  weeks  to  induce AS  model. After  modeling,  each  group  was  given  relevant
          medicine  or  normal  saline  intragastrically,  once  a  day,  for  4  consecutive  weeks. After  the  last  administration,  the  levels  of  total
          cholesterol (TC),  triglycerides (TG),  low-density  lipoprotein  cholesterol (LDL-C),  high-density  lipoprotein  cholesterol (HDL-
          C),  5,6-epoxyeicosatrienoic  acid (5, 6-EET),  8,9-EET,  11,12-EET,  14,15-EET,  interleukin-1β (IL-1β)  and  IL-18  in  serum
          were detected; mRNA expressions of inhibitor of nuclear factor κB (IκB), nuclear factor κB (NF-κB), NOD-like receptor thermal
          protein  domain  associated  protein  3 (NLRP3),  Caspase-1,  IL-1β  and  IL-18  in  the  aortic  tissue  of  mice  were  detected;  protein
          expression  levels  of  IκB,  NF- κB,  NLRP3,  apoptosis-associated  speck-like  protein  containing  CARD (ASC),  Caspase-1,
          gasdermin D (GSDMD), IL-1β and IL-18 in the aortic tissue of mice were detected. The morphological changes of the aortic tissue
          were  observed.  RESULTS  Compared  with  model  group,  the  serum  levels  of  TC,  TG,  LDL-C,  IL-1β  and  IL-18,  the  mRNA
          expressions  of  IκB,  NF-κB,  NLRP3,  Caspase-1,  IL-1β  and  IL-18  in  aortic  tissue,  and  the  protein  expressions  of  IκB,  NF-κB,
          NLRP3,  ASC,  Caspase-1,  GSDMD,  IL-1β  and  IL-18  were  all  decreased  significantly  in  Huayu  qutan  formula  group  and
          rosuvastatin  group (P<0.05),  while  the  serum  levels  of  5,6-EET,  8,9-EET,  11,12-EET  and  14,15-EET  were  increased
                                                             significantly  (P<0.05).  The  aortic  atherosclerotic  plaques
