Abstract: OBJECTIVE:To study the features of the distribution and differentiation ofTraditional Chinese Medicine(TCM)syndromes in patients with diabetic peripheral neuropathy(DPN).METHODS:We collected clinical data on illness course,age,fasting blood glucose,saccharogenic hemoglobin,TCM syndromes,tongue,and pulse of238 DPN patients.Differentiated main syndromes(Yin deficiency and exuberant heat,invasion of spleen by damp-heat,deficiency of both Qi and Yins,and deficiency of both Yin and Yang)and accompanying syndromes(blood stasis and phlegm-dampness)of diabetes were also recorded.The features of DPN syndromes were then analyzed.RESULTS:Among the four main syndromes of diabetes,deficiency of both Yin and Yang was the most common in the 238 DPN patients,of which89%-96%had blood stasis.CONCLUSION:The method of differentiating syndromes of diabetes can be applied to DPN patients.Deficiency of both Yin and Yang,often accompanied by blood stasis,is commonly seen.
