Structural Equation of TCM Syndromes in Acute Exacerbation of Chronic Obstruc-tive Pulmonary Disease
Objective To provide reference for clinical syndrome differentiation and establishing the quantitative standard of TCM syndromes in acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods After clinical investigation,structural equation,an advanced statistical method,was employed to systematically study the TCM syndromes of AECOPD.The data of 100 cases were collected and analyzed by the R language.After exploratory analysis,five common factors(Fl-F5)were extracted by the maximum variance rotation method,and then the syndromes were dif-ferentiated and named according to the TCM theory.Results The structural equation revealed five common TCM syn-dromes of AECOPD,which were wind-cold,kidney deficiency,spleen deficiency,yin deficiency,and phlegm-dampness,and the key points for syndrome differentiation were summarized.There was a good corresponding relationship between the factors in the structural equation and the TCM syndromes of AECOPD.Conclusion Wind-cold,kidney deficiency,spleen deficiency,yin deficiency,and phlegm-dampness were the common TCM syndromes of AECOPD.
