摘要
目的：测量舌尖与舌缘的色度值与色差，为舌尖红的量化诊断提供依据。方法对683名健康体检者进行舌诊，并拍摄舌图像。创建ICC色彩特性文件，对舌图像进行色彩校正。提取舌尖、舌缘的色度值参数（L＊、a＊、b＊、C＊、h°）进行统计分析。采用 CIEDE2000色差公式进行色差计算。结果正常淡红舌的舌尖与舌缘的平均色差为5.4；淡红舌伴有舌尖红时，舌尖与舌缘的平均色差为10.85；各种异常舌色伴有舌尖红时，与没有舌尖红时比较，其平均色差从5.4～7.0增至11.23。结论舌尖红是判断初始热证的灵敏指标。对舌尖红进行量化诊断，对中医“治未病”的热象辨识具有价值，并能进一步揭示舌尖红的诊断意义与科学内涵。
Objective To measure the chromatic differences of the tongue tip and tongue side and provide quantitative evidence for tongue color diagnosis. Methods Totally 683 healthy people were recruited, and their tongue photos were taken. Then ICC specific documents were used for the correction of all tongue photos, and chromatic values （L＊, a＊, b＊, C＊and h°） of tongue tip and tongue side were obtained for further statistical analysis. CIEDE2000 was used for calculating the color differences. Results The average color difference of tongue tip and tongue side in normal pink tongue was 5.4. When pink tongue has abnormal red tongue tip, the average color difference of tongue tip and tongue side was 10.85. Compared with normal tongue tip, the average color difference of tongue tip and tongue side in abnormal color tongue with abnormal red tongue tip increased from 5.4-7.0 to 11.23. Conclusion Red tongue tip is a sensitive sign indicating abnormal heat in the body. Tongue tip quantitative diagnosis is valuable in the determination of heat sign in TCM preventive treatment of disease, and reveal the diagnosis meaning and scientific connotation of red tongue tip.
