Objective To study the correlations between the TCM syndromes of gastrointestinal dyskinesis and the disorders of gastrointestinal hormone

electrogastrogram（EGG） and blood gas in patients with chronic obstructive pulmonary diseases（COPD） and cor pulmonale.Methods The 120 cases of COPD and cor pulmonale were diagnosed with TCM syndrome differentiation

and plasma motilin（MOT）

vasoactive intestinal peptide（VIP）

Gastrin（GAS）

EGG and blood gas were anglyzed and compared with 26 healthy subjects.Results With the aggravation of COPD and cor pulmonale

the dyskinesis of stomach and intestine was getting worse

developed from Shi-excess to Xu-deficiency.In deficiency syndrome

basic electrorhythm decreased most obviously.In phlegm-damp in lung syndrome

MOT and GAS decreased most obviously.In lung-kidney deficiency syndrome and lung-spleen-kidney deficiency syndrome

VIP increased most obviously.In lung-spleen-kidney deficiency syndrome

anoxia and carbon dioxide retention were most serious but GAS increased.Conclusion All patients of COPD and cor pulmonale have dyskinesis of stomach-intestine to a certain degree

abnormal EGG and disordered gastrointestinal hormones.Severity of ventilatory disturbance

quantity of injured organs

and condition of anoxia due to gastrointestinal blood stasis are all correlated with the development of COPD and cor pulmonale.
