中风病舌诊定量研究

目的：应用“中医舌诊专家系统”从舌质、舌苔方面对中风病的证候学进行定量研究。方法：利用彩色数字图像处理和模式识别技术，客观观察了378例中风病患者的舌质、舌苔变化。结果：本组378例中风病患者中以暗红舌最多，共128例（33．86％），暗红舌与淡紫舌、淡白舌、淡红舌、红绛舌、紫红舌、青紫舌相比，其红色分量（R）、绿色分量（G）、蓝色分量（B）值，差异有显著性（P＜0．05，P＜0．01）；本组378例中风病患者各证型舌质的RGB值研究结果显示：本组病例中气虚血瘀证型、风痰阻络证型者的舌质R、G、B值比较，差异有显著性（P＜0．05）。本组378例中风病患者各种舌苔间的R／G、R／B值相比，经方差分析，差异有显著性（P＜0．01）。结论：应用“中医舌诊专家系统”从舌质、舌苔方面对中风病的证候学进行定量研究，为中风病证候规范化、定量化研究奠定了一定的基础。

Quantitative Study on Tongue Diagnosis in Stroke Patients

Objective: To study the tongue proper and tongue fur quantitatively in stroke patients. Methods: Three hundred and seventy eight stroke patients were studied by means of TCM Glossoscopy Expert System, the techniques of color digitized image processing and pattern recognition were applied to objectively study the changes of tongue proper and tongue fur. Results: Dark red tongue was the commonest tongue proper, which revealed in 128 cases (33.86%) in the 378 patients investigated. There was significant difference of red (R), green (G) and blue (B) values in dark red tongue as compared with those in pale purple tongue, pale white tongue, pale red tongue, deep red tongue, purple red tongue and blue purple tongue (P<0 05, P<0 01). Thick and yellow greasy fur was the commonest in 214 cases of acute stage, it accounted for 30.84% and with a total of 66 cases. There was also significant difference in R/G and R/B values among different types of tongue fur (P<0 01). Conclusion: This quantitative study on stroke patients regarding to tongue proper and tongue fur by means of TCM Glossoscopy Expert System provides a base for standardization and quantification of diagnosis of stroke patients.
