Y1 - 2018/05/01 UR - //www.qdcxjkg.com/content/51/5/1701680.abstract N2 -支气管热成术是一种治疗哮喘的方法。目前尚不清楚其对组织病理学的影响是否可以通过气道壁暴露在影响细胞存活所需温度下的比例来充分解释。气道平滑肌和支气管上皮细胞暴露于培养基(37-70°C) 10 s模拟热成形术。在硅片中,我们建立了热成形术后气道热分布的数学模型。在体内,我们测定了14例严重哮喘患者热成形术前后气道平滑肌质量和上皮完整性。体外气道平滑肌和上皮细胞数量在加入加热至≥65°C的培养基后显著减少。在硅模拟中显示,非均匀的热分布在较大的气道中被放大,在内径为4毫米的气道中,有10%的气道壁被加热到60°C。热成形术后6周在体内,哮喘控制有改善(通过哮喘控制问卷-6测量;平均差0.7,95% CI 0.1 ~ 1.3;p=0.03),气道平滑肌质量减少(绝对中位数减少5%,四分位差(IQR) 0-10;p=0.03),上皮完整性增加(14%,IQR 6-29; p=0.007). Neither of the latter two outcomes was related to improved asthma control.Integrated in vitro and in silico modelling suggest that the reduction in airway smooth muscle post-thermoplasty cannot be fully explained by acute heating, and nor did this reduction confer a greater improvement in asthma control.Bronchial thermoplasty treatment for asthma has unexpected possible mechanisms of action http://ow.ly/ZcuE30jsaSa ER -
