          摘   要  目的  研究五宝胶囊通过调节Ⅱ型固有淋巴细胞(ILC2s)上下游细胞因子对哮喘模型小鼠气道炎症的影响。方法  40只
          雌性BALB/c小鼠随机分为正常组、模型组、阳性对照组(地塞米松1 mg/kg)和五宝胶囊低、高剂量组(0.5、1 g/kg),每组8只,通过
          卵清蛋白(OVA)致敏、雾化激发的方法建立哮喘模型,并连续灌胃7 d生理盐水或药液。通过酶联免疫吸附试验检测血清中免疫
          球蛋白E(IgE)、OVA-IgE含量,支气管肺泡灌洗液(BALF)中白细胞介素5(IL-5)、IL-9、IL-13、IL-25、IL-33、胸腺基质淋巴细胞生
          成素(TSLP)、黏蛋白5AC(MUC5AC)含量;采用苏木精-伊红染色观察小鼠肺组织病理变化;采用过碘酸雪夫染色观察杯状细胞
          增生变化;通过流式细胞术检测肺组织中ILC2s的数量(除五宝胶囊低剂量组外)。结果  与模型组比较,五宝胶囊高、低剂量组小
          鼠血清中IgE、OVA-IgE含量和BALF中IL-5、IL-9、IL-13、IL-25、IL-33、TSLP、MUC5AC含量均显著降低(P<0.01),肺组织炎症细
          胞浸润及基底膜增厚均有不同程度的缓解,杯状细胞增生被抑制;五宝胶囊高剂量组小鼠肺组织中 ILC2s 数量显著降低(P<
          0.01)。结论  五宝胶囊能有效减少哮喘模型小鼠肺组织中ILC2s数量,降低小鼠BALF中ILC2s上下游细胞因子的含量,从而抑制
          气道炎症,改善哮喘。

          ABSTRACT    OBJECTIVE To study the effects of Wubao capsule on airway inflammation in asthmatic model mice by regulating
          upstream  and  downstream  cytokines  of  type  Ⅱ  innate  lymphoid  cells (ILC2s).  METHODS  Totally  40  female  BABL/c  mice  were
          randomly divided into normal group, model group, positive control group (dexamethasone 1 mg/kg), Wubao capsule low-dose and
          high-dose  groups (0.5,  1  g/kg),  with  8  mice  in  each  group. Asthma  models  were  induced  by  ovalbumin (OVA)  sensitization  and
          nebulization. Each group was given normal saline or drug intragastrically for 7 consecutive days. The contents of IgE and OVA-IgE
          in serum, the contents of interleukin 5 (IL-5), IL-9, IL-13, IL-25, IL-33, thymic stromal lymphopoietin (TSLP) and mucin 5AC
         (MUC5AC) in bronchoalveolar lavage fluid (BALF) were determined by ELISA. HE staining was used to observe the pathological
          changes  of  lung  tissues  in  mice.  PAS  staining  was  used  to  observe  the  changes  of  goblet  cell  proliferation  in  each  group.  The
          number  of  ILC2s  in  lung  tissue  was  determined  by  flow  cytometry (except  for  Wubao  capsule  low-dose  group).  RESULTS
          Compared  with  model  group,  the  contents  of  IgE  and  OVA-IgE  in  serum  and  the  contents  of  IL-5,  IL-9,  IL-13,  IL-25,  IL-33,
          TSLP  and  MUC5AC  in  BALF  were  significantly  reduced  in  Wubao  capsule  high-dose  and  low-dose  groups (P<0.01).  The
                                                              infiltration  of  inflammatory  cells  and  the  thickening  of
