          摘  要  目的  研究麻黄-桂枝药对对哮喘寒饮蕴肺证大鼠呼吸功能和气道炎症的影响及作用机制。方法  将60只Wistar大鼠随
          机分为空白组、模型组、地塞米松组[1 mg/(kg·d)]和麻黄-桂枝低、中、高剂量组[0.234、0.936、1.872 g/(kg·d)],每组10只。模型组
          和各给药组大鼠通过腹腔注射抗原液(卵清蛋白100 mg+氢氧化铝100 mg)致敏、1%卵清蛋白雾化激发哮喘,并在此基础上施以
         “形寒、饮冷”刺激,建立哮喘寒饮蕴肺证大鼠模型。从实验第2天开始,各组大鼠灌胃相应药物或生理盐水,每天1次,连续给药
          21 d。观察各组大鼠在实验过程中的一般行为学变化,测定造模前和末次给药后的肺功能指标[呼气流量峰值(PEF)、气道阻力
         (Raw)、功能残气量(FRC)、呼气中期流速(EF50%)]以及末次给药后血清中白细胞介素6(IL-6)、IL-13、肿瘤坏死因子α(TNF-α)、
          干扰素γ(IFN-γ)含量,观察大鼠的肺组织病理学形态变化,检测其肺组织中IL-6、IL-13、TNF-α、IFN-γ、胸腺基质淋巴细胞生成素
         (TSLP)、Toll样受体4(TLR4)mRNA及TSLP、TLR4蛋白表达水平。结果  与模型组比较,地塞米松组和麻黄-桂枝中、高剂量组大
          鼠肺组织损伤明显减轻;Raw,FRC,IL-6、IL-13、TNF-α含量及mRNA表达水平,TSLP、TLR4 mRNA及蛋白的表达水平均显著降
          低(P<0.05);PEF、EF50%和IFN-γ含量及mRNA表达水平均显著升高(P<0.05);只有少数大鼠出现哮喘典型症状。结论  麻黄-
          桂枝药对能显著改善哮喘寒饮蕴肺证大鼠的呼吸功能,减轻气道炎症,其作用机制可能与抑制 TSLP/TLR4 信号通路、调节 Th1/
          Th2失衡有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  effects  of  Ephedra-Cinnamomum  couplet  medicinals  on  respiratory  function  and
          airway inflammation in rats with asthma of cold-fluid retention in lung syndrome and its mechanism. METHODS Sixty Wistar rats
          were  randomly  divided  into  blank  group,  model  group,  dexamethasone  group  [1  mg/(kg·d)],  and  Ephedra-Cinnamomum  low-,
          medium-,  high-dose  groups  [0.234,  0.936,  1.872  g/(kg·d)],  with  10  rats  in  each  group.  The  model  and  treatment  groups  were
          sensitized by intraperitoneal injection of antigen solution (ovalbumin 100 mg + aluminum hydroxide 100 mg) and challenged with
          1% ovalbumin nebulization, along with exposure to a cold environment and ingestion of cold water, to establish the asthma model
          with cold-fluid retention in lung syndrome. From day 2, rats received corresponding drugs or normal saline intragastrically, once a
          day, for 21 consecutive days. The general behavioral changes in each group of rats were observed during the experimental process.
          The  lung  function  parameters  [peak  expiratory  flow (PEF),  airway  resistance (Raw),  functional  residual  capacity (FRC),
                                                             expiratory  flow  at  50%  of  forced  vital  capacity (EF50%)]
