囊性纤维化病人肺脏逐渐遭到破坏。最早的病理学改变发生在小气道,常规呼吸功能测定无法发现。当肺疾病加重时,常产生大量富含细胞的痰。痰中去氧核糖核酸(DNA)排出量可反映出疾病发展过程中炎性单核细胞及肺细胞的丧失量。本文研究了7例肺囊性纤维化长期咳痰的病人。对5例门诊病人进行了3种物理治疗,每种治疗持续 Cystic fibrosis patients gradually destruct the lungs. The earliest pathological changes occurred in the small airways, routine respiratory function test can not be found. When lung disease aggravates, it often produces a lot of cell-rich sputum.

This article studied 7 cases of chronic cystic fibrosis patients expectoration. Three physical treatments were performed on five outpatients, each of which continued
