Objective To establish the decision tree model of Yang deficiency syndrome and clinical conventional indexes in type 2 diabetes mellitus patients.Methods Syndrome decision and clinical indexes collection from 249 type 2 diabetes mellitus patient were observed and analyzed.Tree structure model were built to summarize the correspondence between Yang deficiency syndrome and clinical conventional indexes based on T test,nonparametric analysis,and Spearman correlation analysis.Results The Yang deficiency syndrome accounted for 31.33% of 249 type 2 diabetes mellitus patients.The accuracy identification rate of tree structure model of Yang deficiency syndrome with four core index,such as LPa、FT3、TSH、FINS was 84.74%,the sensitivity and specificity were 74.36% and 89.47%.Conclusion Decision tree model can identify Yang deficiency syndrome of type 2 diabetes mellitus patients clearly and more intuitive.Decision tree model can provide the chance of syndrome objective.

Objective To explore the risk factors of Qi deficiency syndrome of type 2 diabetes mellitus and to provide evidence for prevention and cure diabetes mellitus with TCM.Methods On the basisof the epidemiological survey,147 cases of Type 2 diabetes mellitus were collected and divided into Qi deficiency syndrome group and non-Qi deficiency syndrome group.The relationships between risk factors and Qi deficiency syndrome were analyzed by unconditional univariate and multivariate Logistic regression.Results Two hours postprandial blood sugar[2PPBS (β value is-0.764,OR (95%CI) is 0.466 (0.236 ~ 0.919)],apolipoprotein-B [APo-B (β value is-1.005,OR (95%CI)is 0.366 (0.140~0.959)],urine glucose [β value is-1.300,OR(95%CI)is 0.273 (0.127~0.584)] were inverse correlation with Qi deficiency syndrome of type 2 diabetes mellitus.Conclusion Qi deficiency syndrome of type 2 diabetes mellitus was inverse correlation with 2PPBS、APo-B and urine glucose.
