To investigate self Baoyuantang subtraction Treating Chronic obstructive pulmonary disease remission of clinical effect.Methods:April 2010-November 2013 between our hospital was diagnosed with chronic obstructive pulmonary disease patients in remission 130 cases for the study were randomly divided into control group and observation group，75 cases in the control group patients treated with conventional western medicine treatment，patients in the observation group on the basis of conventional western medicine plus service，“self Baoyuantang” The total after two groups of patients after treatment efficiency，control penetrance，referring to the pulse of oxygen，pulse oxygen saturation that rate of decline，6min walking distance，FEV1 lung function before and after treatment，FEV1 / FVC，and body mass index of patients were compared.Results:The patients treated with total efficiency of 81.6%，the control rate was 48.3%，mean pulse oxygen，oxygen desaturation that pulse rate lower than the control group，6MWD shorter than the control group，and P<0.05，the difference was significant sex; FEV1 lung function before and after treatment，FEV1 / FVC and body mass index did not change significantly.Conclusion:“Self Baoyuantang” subtraction Treating Chronic obstructive pulmonary disease remission of clinical effect is significant，worth learning clinical medicine.
