          摘  要  目的  基于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)炎症小体信号通路,探讨蠲哮汤改
          善支气管哮喘(简称“哮喘”)的潜在机制。方法  将雌性SD大鼠随机分为正常组,模型组,蠲哮汤低、中、高剂量组(0.36、0.72、1.44
          g/kg,以生药量计),阳性对照组(醋酸地塞米松片,0.2 mg/kg),每组10只。除正常组外,其余大鼠均按腹腔注射鸡卵清白蛋白+氢
          氧化铝联合雾化吸入鸡卵清白蛋白的方式构建哮喘模型。从实验第14天起,各组大鼠灌胃相应药液或生理盐水,每天1次,连续
          7 d。末次给药后,检测各组大鼠肺功能指标(用力肺活量、第0.3秒用力呼气容积、呼气流量峰值)、血清炎症指标(白细胞介素1β、
          白细胞介素18)水平、支气管肺泡灌洗液中炎症细胞(淋巴细胞、嗜酸性粒细胞、中性粒细胞)百分比,观察其肺组织病理改变,并
          检测其肺组织中核因子κB(NF-κB)、NLRP3、胱天蛋白酶1(caspase-1)蛋白及mRNA的表达情况。结果  与正常组相比,模型组大
          鼠可见肺泡壁增厚、炎症细胞浸润等病理改变;模型组和各药物组大鼠的各项肺功能指标均显著降低,炎症指标水平、炎症细胞百
          分比以及NF-κB、NLRP3、caspase-1蛋白及mRNA的表达均显著升高或上调(P<0.05)。与模型组相比,蠲哮汤各剂量组大鼠的病
          理改变明显缓解,各定量指标均呈剂量依赖性改善(P<0.05)。结论  蠲哮汤可减轻哮喘大鼠的气道炎症反应,缓解肺功能损伤,
          改善炎症细胞浸润等病理改变;上述作用可能与抑制NLRP3炎症小体信号通路有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  potential  mechanism  by  which  Juanxiao  decoction  improves  bronchial  asthma
         (hereinafter  referred  to  as “asthma”)  based  on  the  nucleotide-binding  domain  leucine-rich  repeat  and  pyrin  domain-containing
          receptor  3 (NLRP3)  inflammasome  signaling  pathway.  METHODS  Female  SD  rats  were  randomly  assigned  to  normal  group,
          model  group  and  Juanxiao  decoction  low-,  medium-  and  high-dose  groups (0.36,  0.72  and  1.44  g/kg,  calculated  based  on  crude
          drug  weight),  as  well  as  positive  control  group (Dexamethasone  acetate  tablets,  0.2  mg/kg),  with  10  rats  in  each  group.  Except
          for the normal group, asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined
          with  aluminum  hydroxide,  followed  by  nebulized  inhalation  of  ovalbumin.  On  day  14  of  the  experiment,  rats  in  each  group
          received  intragastric  administration  of  the  corresponding  solution  or  normal  saline,  once  a  day,  for  7  consecutive  days.  Following
          the  final  administration,  the  following  parameters  were  measured  in  each  group:  lung  function  indexes (forced  vital  capacity,
          forced expiratory volume in 0.3 second, peak expiratory flow), serum levels of inflammatory markers (interleukin-1β, interleukin-
          18),  and  the  percentages  of  inflammatory  cells (lymphocytes,  eosinophils,  neutrophils)  in  bronchoalveolar  lavage  fluid.
          Histopathological  changes  in  lung  tissue  were  observed,  and  the  protein  and  mRNA  expressions  of  nuclear  factor-kappa  B (NF-
          κB), NLRP3 and caspase-1 in lung tissue were detected. RESULTS  Compared with the normal group, pathological changes such
          as  alveolar  wall  thickening  and  inflammatory  cell  infiltration  were  observed  in  rats  in  the  model  group.  All  pulmonary  function
                                                             indicators were significantly reduced in rats in the model group
