研究简介（原文）
The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists and long acting muscarinic antagonists. We are interested in determining whether the large and/or small airways are the predominant site of airflow limitation. We are also interested in determining whether intrinsic small airways obstruction and/or loss of lung elastic recoil is responsible for expiratory airflow limitation and to what extent may be attributed to loss of lung elastic recoil vs decreased airway conductance in peripheral airways. We are also interested to evaluate the role of varying doses of inhaled corticosteroids to suppress large and small airway inflammation using exhaled nitric oxide as surrogate markers of inflammation. For comparison purposes, spirometry and measurements of exhaled nitric oxide will also be obtained if possible during a naturally occurring exacerbation of asthma. High resolution thin section CT of the lung will also be obtained. Analysis will evaluate integrity of the lung parenchyma as to absence and or presence of emphysema and extent of emphysema using voxel quantification. We will also investigate optical coherence tomography to detect clinically unsuspected emphysema. We will also obtain autopsy material when available in asthmatics who expire. Will also measure serum periostin as a marker of inflammation by collaborating with Genetech in San Francisco.

这项试验目前在中国大陆没有研究中心
这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
