To explore the relation between Chinese medical patterns for primary glomerulopathy and tongue form indices.Methods:116 patients were classified into Qi deficiency, Yang deficiency, Yin deficiency, and deficiency of both Qi and Yin in terms of root-deficiency; and divided to water-damp, damp-heat, damp-turbid and blood stagnation in terms of branch-excess. Wecollected data with tongue form processing equipment, and obtained indices with computers. By macroscopic observation and quantitative analysis of tongue images, differences among the tongue form indices of various Chinese medical patterns were studied.Results:There was no significant difference among various types (P>0.05).Conclusion:The enlarged teeth-marked tongue may be related to pattern of Qi-deficiency water-damp. Tongue form indices are helpful for pattern differentiation.
