高血压病裂纹舌患者的舌面诊图像特征参数分析

Analysis of characteristic parameters of tongue and face image in patients with hypertensive fissured tongue

目的:分析高血压病裂纹舌患者的舌面诊图像参数特征。方法:运用TF-Ⅰ型中医舌面诊断一体仪,采集心内科住院部87例高血压病患者的舌面诊图像,以裂纹舌的有无分为裂纹舌组与非裂纹舌组,依照RGB和HSV色彩空间模型,对两组的颜色参数进行比较分析。结果:高血压病裂纹舌组的舌象参数的饱和度S值较大,红、绿、蓝(R、G、B)颜色分量值小,裂纹舌组舌中、舌根部位的舌苔R、G、B值均小于非裂纹舌组(P<0.05);裂纹舌组面色整体及其各个分部的H值较小,鼻部、下颌部、口唇部的V值均小于非裂纹舌组(P<0.05)。结论:高血压病裂纹舌的出现伴随有舌、面诊图像特征参数的变化,提示了高血压病胃肾津液耗伤、肝肾阴虚阳亢的病机。

Objective:To analyze the parameters of the tongue and face image of patients with hypertensive fissured tongue.Methods:Tongue and face image of 87 hypertension inpatients were collected by TF-I tongue-face-pulse digital analysis instrument and the characteristics of tongue color parameters of patients with fissured tongue and non-fissured tongue were analyzed based on red,green,blue(RGB)and hue,saturation,value(HSV)color space model.Results:Compared with the nonfissured tongue group,the S-values of the fissured tongue patients were larger,and the R,G and B values were smaller.In the fissured tongue group,the R,G,B values of the tongue coating in the middle of tongue and tongue root were smaller than those in the non-fissured tongue group,and the differences were statistically significant(P<0.05).The overall face color of the fissured tongue group and H values were smaller than that in the non-fissured tongue group.The V values of the nasal,mandibular and lip of the fissured tongue group were smaller than those of the non-fissured tongue group,and the differences were statistically significant(P<0.05).Conclusion:There are characteristics parameters of tongue color changes of hypertensive patients with fissured tongue,which indicated that the pathogenesis of hypertension is deficiency of fluid in stomach and kidney,deficiency of liver and kidney yin and hyperactivity of yang.
