Evolution Law of Gout Etiology and Pathogenesis Based on Similarity Algorithm
Objective:To explore the use of similarity algorithm in order to sort out the inheritance and development of traditional Chinese medicine(TCM)etiology and pathogenesis of gout.Methods:Using ontology concept similarity to compare the differences in doctors'understanding of the etiology and pathogenesis of gout in different periods,and present the evolution process of gout etiology and pathogenesis understanding.Results:The results of the similarity of etiology and pathogenesis showed that the similarity of etiology and pathogenesis between the Northern and Southern dynasties and the Sui and Tang dynasties was the highest(56%),and the similarity between the Song and Yuan dynasties was the lowest(28.5%).Before the Sui and Tang dynasties,doctors had a relatively concentrated understanding of the etiology and pathogenesis of gout.After the Song dynasty,doctors gradually diversified their understanding of this disease.The similarity of etiology results showed that the similarity of etiology understanding before the Song dynasty was relatively high.After the Song dynasty,it showed a downward trend and gradually stabilized.Before the Song dynasty,the main stream in the medical field believed that gout was caused by external contraction,mainly wind,cold,and dampness pathogens.After the Song dynasty,some doctors had different ideas and believed that gout was caused by internal damage,resulting in yang deficiency,yin deficiency,internal heat,internal dampness,and phlegm and blood stasis,and dietary internal damage could induce these conditions.There were records of qi stagnation in the Yuan dynasty for the cause of gout.During the Ming and Qing dynasties,doctors had a deeper and more specific understanding of the cause of gout,and believed that internal heat,blood deficiency,and qi deficiency are the main reason,followed by qi stagnation,blood stasis,yin deficiency,and endogenous dampness.The similarity of disease location results showed that the similarity of disease location between dynasties before the Ming dynasty was 0,while between Ming and Qing dynasties was 48.1%,and the disease location generally involved the liver,kidney,spleen and stomach.Conclusion:Gout generally belongs to deficient root and excessive superficiality syndrome,with liver,spleen,and kidney deficiency as the root,dampness,heat,phlegm and stasis,and blood heat and qi stagnation as the superficiality.It is often induced by external factors or diet internal injury.This article uses the text similarity algorithm to concatenate the evolution process of the TCM etiology and pathogenesis theory of gout,proving that this method is feasible in exploring the evolution laws of TCM theory.
