目的:探讨小青龙汤对哮喘小鼠肺组织气道重塑干预作用及对转化生长因子-β1(transforming growth factor-β1,TGF-β1)及白细胞介素-13(Interleukin 13,IL-13)表达的影响。 方法:40只雌性小鼠随机分成正常对照组、哮喘模型组、小青龙汤组和强的松组。采用卵蛋白(OVA)致敏2周及OVA滴鼻(共18次)激发6周建立哮喘小鼠模型。小青龙汤组和强的松组分别于每次激发前30 min采用小青龙汤和强的松干预,共6周。HE染色观察各组小鼠肺组织病理变化,Image-Pro Plus 6.0彩色图像分析系统测定支气管壁及平滑肌厚度,免疫组化法和实时定量PCR检测肺组织中TGF-β1和IL-13表达。 结果:哮喘模型组发生支气管管壁增厚、炎症细胞浸润、平滑肌增生等气道重塑的特征性改变。小青龙汤组和强的松组支气管壁及平滑肌厚度低于哮喘模型组 (P<0.05)。免疫组化结果显示:正常组肺组织TGF-β1和IL-13阳性较弱,主要分布在支气管壁;与正常组比较,哮喘模型组TGF-β1和IL-13呈强阳性表达于支气管壁。与哮喘模型组相比较,小青龙汤组和强的松组显著抑制TGF-β1和IL-13基因表达(P<0.05)。 结论:TGF-β1和IL-13高表达可能在哮喘气道重塑中起重要作用。小青龙汤改善哮喘小鼠气道重塑可能通过抑制肺组织TGF-β1和IL-13表达而实现。
Objective:To investigate the effects of “Xiaoqinglong Decoction” (XQLD) on the airway remodeling and the expression levels of TGF-β1 and IL-13 in lung tissue of mice with asthmatic airway remodeling. MethodsForty healthy female BABL/c mice were randomly divided into four groups, which consisted of normal control group, asthmatic model group, XQLD group and prednisolone group. The mice were sensitized for 2 weeks and stimulated for 6 weeks by ovalbumin to establish the asthmatic airway remodeling mice model. XQLD group and prednisolone group were given XQLD or prednisolone before each stimulation for 6 weeks. The pathological changes were observed by slicing lung tissues and stained with HE. The thickness of bronchial wall and airway smooth muscle were measured by optical microscope and the Image-Pro Plus 6.0. The expressions of TGF-β1 and IL-13 in lung tissues were observed by immunohistochemistry and detected by Real-time quantitative PCR. Results:Bronchial wall thickened, inflammatory cell infiltration, smooth muscle hypertrophied and airway remodeled were found in asthmatic model mice. The thickness of bronchial wall and smooth muscle of XQLD group and prednisolone group were less than asthmatic model group. As the result of immunohistochemistry, there were weak expressions of TGF-β1 and IL-13 mainly on bronchial wall in normal control group. Compared with normal control group, the expressions of TGF-β1 and IL-13 were more obvious in asthmatic model group. The gene expressions of TGF-β1 and IL-13 of XQLD group and prednisolone group were significantly lower than asthmatic model group(P<0.05). Conclusion:The high expressions of TGF-β1 and IL-13 might play an important role in developing airway remodeling of asthma. “Xiaoqinglong Decoction” has some inhibitory effect on airway remodeling in asthmatic mice by inhibiting the expressions of TGF-β1 and IL-13 in lung tissues probably.
