Objective To explore the clinical effect and lung CT change of long-term used of low-dose roxithromycin in treatment for bronchial expansion patients in stable phase. Methods 94 cases collected in the Department of Respiration, The Second Hospital Affiliated to Suzhou University from February 2011 to December 2012 were diagnosed as bronchiectasis, 34 cases in control group were given oral treatment for ambroxol 30 mg, three times one day, 60 cases in treatment group were added roxithromycin 75 mg on basis of control group, two times one day. Patients in two groups were both treated for 6 months. The therapeutic effect and the score of life quality and dyspnea scores in two groups were observed, and the changes of CT data were compared before and after treatment. Results After treatment, the life quality score and dyspnea score of two groups were all improved, but the treatment group was signiifcantly higher than the control group (P<0.05). The effective rate in treatment group was 86.67%, which was signiifcantly higher than 70.59%in the control group (P<0.05). After treatment, chest CT imaging score of patients in treatment group were improved, signiifcantly better than that in the control group (P<0.05).
