Relationship Between TCM Syndrome Patterns and Physicochemical Parameters of Chronic Obstructive Pulmonary Disease: A Report of 500 Cases / 广州中医药大学学报

ABSTRACT

[Objective] To explore the relationship between TCM syndrome patterns and physicochemical parameters of chronic obstructive pulmonary disease (COPD). [Methods] Five hundred hospitalized cases of COPD were investigated. The correlation of TCM syndrome patterns with pulmonary function, blood analysis and biochemical indexes were assayed by logistic forward regression analysis and linear multiple regression analysis, and then the above indexes were analyzed by independent- samples t test. [Results] Five equations were obtained by logistic regression. Positive correlation was found between the number of white blood cells (WBC) and the pattern of phlegm-heat blocking lung, hemoglobin (HGB) level and the pattern of yang deficiency with fluid retention, as well as red cell distribution width (RDW) and the pattern of kidney deficiency. Maximal expiratory flow rate in residual 75 % vital capacity ( MEF75), peak of expiratory flow (PEF) and mean corpuscular hemoglobin (MCH) were negatively correlated with the pattern of yang deficiency with fluid retention. Maximal expiratory flow rate in residual 25% vital capacity (MEF25) and granulocyte percentage (GP) were also negatively correlated with the pattern of spleen deficiency. So did potassium ions (K+ ) level and the pattern of kidney deficiency, t test showed the same results. [Conclusion] The above indexes have great value for TCM syndrome differentiation of COPD.
