[Discussion of Syndrome Elements for Chronic Glomerulonephritis on the Basis of Factor Analysis Method].

Objective To preliminarily observe syndrome elements of chronic glomerulonephritis by using factor analysis method. Methods Data of four diagnostics were collected from 289 chronic glo- merulonephritis outpatients and inpatients at Dongzhimen Hospital between February 2011 and February 2012. Under the guidance of Chinese medicine ( CM) , the distribution features of syndrome elements of chronic glomerulonephritis were preliminarily observed using factor analysis method. Results The primary locations of syndrome element were Pi and Shen, and followed by Gan and Fei. The primary nature of syndrome elements were qi deficiency, yin deficiency, and yang deficiency. The primary pathogenic factors of syndrome elements were water dampness, heat, and blood stasis. Conclusions Using factor analysis method, syndrome elements of chronic glomerulonephritis were primarily summarized as four aspects : dampness, heat, stasis, and deficiency. Of them , deficiency was an important pathogenic fac- tor. Sthenic syndrome was seldom seen. Dampness was an important pathogenic factor.
