Research on Correlation of TCM Syndromes with Region Factor in The First Year after First Ischemic Stroke

This article was aimed to study the correlation of traditional Chinese medicine (TCM) syndromes with region factor in the first year after first ischemic stroke. Cross-sectional study was applied in the data collection of TCM four examinations among subjects in China using the same observing rating scale. The results showed that subjects of North China were mainly presented with the syndromes of qi-deficiency, internal-heat and phlegm-damp;subjects of Middle China were mainly presented with the syndrome of qi-deficiency; and subjects of East and South China were mainly presented with the syndrome of qi-deficiency and blood-stasis. The proportion of internal-heat was obviously higher in North China than in South China; that of phlegm-damp was remarkably higher in North China than in Middle and East China; and that of blood-stasis was significantly lower in Middle China than in East and South China. It was concluded that the distribution of internal-heat and blood-stasis was significantly affected by factor of region. Patients in North and South China differed greatly in TCM syndrome. Internal-heat is the main syndrome in North China, while blood-stasis in South China.
