Study on the Correlation Between Objective Characteristics of Tongue Image of Hypertension and Syndrome Element of Phlegm

Objective To analyze the correlation between pathological degree and tongue features through observing tongue image of syndrome element of phlegm in hypertension patients.Methods A total of 315 hypertension patients in The First Affiliated Hospital of Hunan University of traditional Chinese medicine(TCM)from March 2019 to August 2019 were recruited,and divided into non-phlegm syndrome element group(n=99),mild phlegm syndrome element group(n=116)and severe phlegm syndrome element group(n=100)based on the phlegm syndrome element score.Standard tongue image of each patient was collected using a tongue diagnosis instrument.The correlation of tongue image characteristics of patients was analyzed based on the color spaceand texture indexes by using Pearson and Kruskal-Wallis H test.Results With the aggravation of the degree of phlegm syndrome element in hypertension patients,the color index values of red(R),green(G)and blue(B)of tongue body(TB)and tongue coating(TC)increased,and the increasing degree of R and B was much higher than that of G value;the value of TB intensity(I)increased and the saturation(S)decreased;the value of texture index of TB angular second moment decreased,while TB entropy and TB mean increased;TC area/total tongue area increased. The pathological grade of syndrome element of phlegm was positively correlated with TB-R, TB-G, TB-B, TC-G, TC-B, TB-I, TB entropy, TB mean and TC area/total tongue area (P<0.05), while negatively correlated with TB-S and TB angular second moment (P<0.05). Conclusion Objective index of the tongue image is sensitive in reflecting syndrome element of phlegm in hypertension. Tongue features are basically consistent with TCM theories and clinical conclusions. Therefore, objective index of the tongue image has unique advantages and application value in the diagnosis of hypertension.
