To evaluate the effects between Chinese medical syndrome differentiation and treatment and low-dose erythromycin for the treatment of bronchiectasis of stable period. Methods:A total of 102 patients with stable bronchiectasis were randomly divided into control group and TCM group. Efficacy measures were dyspnea scores(MMRC), scores of StGeorges respiratory questionnaire(SGRQ), the frequency of acute exacerbations, pulmonary function test and HRCT. Results:After the six months of treatment, four cases in the TCM group and the control group dropped out. The score of dyspnea and the frequency of acute exacerbations of the TCM group decreased significantly than the control group (P<0.05). And the scores of StGeorges respiratory questionnaire of the TCM group decreased significantly (P<0.05). Conclusion:The TCM group which mainly based on Chinese drugs for benefiting-qi，activating-blood may improve conditions of patients with bronchiectasis, enhance the quality of life and reduce the frequency of acute exacerbations. Therefore, it is worthy of further study.
