Objective:To study the tongue characteristic of peole with uteru fibroids,and use chromaticity methord to analyze the chromatic value of tongue color.Methods:This study use case control study methord(1∶1),to observe and take tongue pictures of 244 people with uteru fibroids and other 244 without,and then compare their tongue color,lingual contour,fur color,fur thick and tongue color chromatic value.Results:to observe by naked eye,there are no diffrence in tongue color、fur color and fur thick between the uteru fibroids and non-uterine group,but the normal linguiform frequency degrade signifcantly in uteru fibroids group,the most popular abnormal linguiform is dark tongue.In LCH color space, the tongue color of uteru fibroids people lean to reddish orange,but its lean to red in non-uterine group.The colour saturation degrade in spotted tongue and dark tongue.Conclusions:The frequency of spotted tongue and dark tongue increase in uteru fibroids people.chromaticity methord can make the tongue diagonis more exact.
