脾气虚证、脾阳虚证、脾阴虚证的舌诊客观指标对比分析

目的：对脾气虚证、脾阳虚证、脾阴虚证开展舌象信息参数分析，探讨脾虚证诊断标准客观化、定量化、标准化研究思路与方法。方法：运用舌象采集系统采集体检人群中脾气虚、脾阳虚、脾阴虚和健康人的舌象样本，各30名，并对舌象信息参数进行分析，比较各组的舌色、舌质、苔色和苔质等舌象信息参数差异。结果：舌色、苔色Lab值比较，各组舌色a值、舌色b值、苔色b值比较，无显著性差异（P>0.05）；脾气虚、脾阳虚总体舌质偏淡苔白，脾阳虚组的舌色L值最大，脾阴虚组苔色a值最大。舌质、苔质比较，脾阳虚组、脾气虚组多舌体胖伴齿痕，健康组多舌体适中，少有齿痕，而脾阴虚组舌体偏瘦伴裂纹多见。舌苔分布比较，脾阳虚组则以苔偏厚偏腻多见，脾阴虚组以少苔多见。结论：本研究初步验证了通过舌象特征信息采集量化分析可作为脾气虚、脾阳虚、脾阴虚等脾虚类证鉴别诊断的量化参考指标，对辅助临床诊疗具有一定的应用价值。

Comparative analysis of tongue diagnosis objective indexes of spleen qi deficiency syndrome, spleen yang deficiency syndrome and spleen yin deficiency syndrome

Abstract : Objective : To analyze the tongue image information parameters of spleen qi deficiency syndrome, spleen yang deficiency syndrome and spleen yin deficiency syndrome, and to explore the objective, quantitative and standardized research ideas and methods of the diagnostic criteria of spleen deficiency syndrome. Methods : The tongue image acquisition system was used to collect the tongue image samples of spleen qi deficiency, spleen yang deficiency, spleen yin deficiency and healthy people in the physical examination population, 30 cases in each group, and the tongue image information parameters were analyzed. The differences of tongue image information parameters such as tongue color, tongue quality, fur color and fur quality were compared. Results : There was no significant difference in tongue color a value, tongue color b value and moss color b value between the groups ( P > 0.05 ). The tongue color L value of the spleen yang deficiency group was the largest, and the moss color a value of the spleen yin deficiency group was the largest. Compared with the tongue and coating, the spleen yang deficiency group and the spleen qi deficiency group had more tongue body fat with tooth marks, the healthy group had more tongue body moderate and less tooth marks, while the spleen yin deficiency group had more tongue body lean with cracks. Comparing the distribution of tongue coating, the spleen yang deficiency group was more common in the thick and greasy coating, and the spleen yin deficiency group was more common in the less coating. Conclusion : This study preliminarily verified that the quantitative analysis of tongue feature information collection can be used as a quantitative reference index for the differential diagnosis of spleen deficiency syndromes such as spleen qi deficiency, spleen yang deficiency and spleen yin deficiency, which has certain application value for assisting clinical diagnosis and treatment.
