Objective  To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in treating
chronic obstructive pulmonary disease (COPD) in a stable stage.
Methods  We searched MEDLINE (1950 to July 2008), PubMed (1996 to July 2008), VIP (1989 to July 2008), WanFang (1998 to July 2008), CNKI (1979 to July 2008), and CBM (1978 to July 2008)for randomized control trials about TCM to treat stable COPD. Trial screening, quality assessment of included trials, and data extract were conducted. Statistical analysis was conducted by using RevMan 4.2.7 software.
Results   A total of 30 randomized controlled trials (RCTs) in the Chinese language were identified. No pooled analysis was performed because of the significant heterogeneity among the included trials. (1) For TCM alone versus blank therapy or placebo: 3 RCTs reported the clinical effective rate and only 1 indicated TCM was more effective; 5 RCTs reported forced expiratory volume in one second (FEV1)% after treatment and 2 indicated TCM alone as more effective in improving lung function; 4 RCTs reported quality of life after therapy and 2 indicated TCM alone was more effective in improving quality of life after therapy. (2) For integrated tradtional and western medicine versus western medicine alone: 11 RCTs included the clinical effective rate, 3 RCTs showed that integrated traditional and western medicine was more effective. Of 8 RCTs reporting FEV1%, 2 RCTs suggested that integrated traditional and western medicine was more effective. There were 3 RCTs studying 6 minute walking distance and 4 RCTs about quality of life, which also showed that integrated traditional and western medicine was more effective. No obvious adverse reaction to TCM was reported.
Conclusions  The current evidence shows TCM tends to relieve the symptoms and improve quality of life for patients with stable COPD without obvious adverse reaction. Due to the low methodological quality of trials included, more RCTs
of high quality and large scale are required.
