摘要： 目的初步探析丹龙定喘汤对哮喘豚鼠气道重塑的作用及机制。
方法〗选取健康雌性豚鼠24只，按体质量分层随机分为4组：空白对照组、模型对照组、地塞米松组、丹龙定喘汤组，每组6只。采用卵蛋白致敏法建立豚鼠哮喘气道重塑模型，以丹龙定喘汤干预，并以地塞米松做对照药物，治疗1个月后分别检测气道重塑的程度及豚鼠肺组织中转化生长因子β1（TGFβ1)含量。
结果(1)模型对照组豚鼠肺支气管管壁和平滑肌层明显增厚，与空白对照组相比差异有统计学意义（P<0.05）;丹龙定喘汤组气道壁厚度减轻，与模型对照组相比差异有统计学意义（P<0.05），与地塞米松组相比，差异无统计学意义(P＞0.05)。(2)模型对照组豚鼠肺组织中的TGFβ1含量明显增加，与空白对照组相比，差异有统计学意义（P<0.05）；丹龙定喘汤组TGFβ1含量减少，与模型对照组相比差异有统计学意义（P<0.05），与地塞米松组相比差异无统计学意义（P＞0.05）。
结论丹龙定喘汤对哮喘豚鼠气道重塑有一定抑制作用，其机制可能是通过下调哮喘豚鼠肺组织中的TGFβ1水平,抑制气道平滑肌细胞及细胞外基质的增殖而阻断气道重塑的进程。

Abstract: ObjectiveTo make a preliminary exploration of the effectiveness and mechanism of Danlong pantingarresting decoction in airway remodeling in asthmatic guinea pig.
MethodsTwentyfour healthy female guinea pigs were divided into four groups randomly（n=6，in each group）：normal control group, model control group，dexamethasone group，and Danlong pantingarresting decoction group.The asthmatic guinea pig airway remodeling model was established by ovalbumin sensitized method,Danlong pantingarresting decoction was applied to intervene，and dexamethasone was used as control drug.After one month,detect the extent of airway remodeling and determine TGFβ1 level in guinea pig lung tissues.
Results（1）Compared with normal group，WAt/Pi，WAm/Pi were significantly increased(P<0.05) in model group.Compared with model group，the airway wall thickness reduced in Danlong pantingarresting decoction group，there being a significant difference(P<0.05),but no significant difference compared with dexamethasone group(P>0.05).(2)Compared with normal group，the extent of lung tissue TGFβ1 was significantly increased in the model group(P<0.05).Compared with model group，the TGFβ1 content was decreased in Danlong pantingarresting decoction group，there being a significant difference(P<0.05),but no significant difference compared with the dexamethasone group(P>0.05).
ConclusionsDanlong pantingarresting decoction plays an inhibitory role in airway remodeling of asthmatic guinea pigs.It may reduce the TGFβ1 level of lung tissues in asthmatic guinea pigs，thus inhibit airway proliferation of smooth muscle cells and extracellular matrix and block the airway remodeling process.
