摘要
目的评价舌下络脉表现对于血瘀证的诊断价值。方法选择血瘀证较多见且较典型的三种疾病(冠心病、肺心病与原发性痛经),按目前诊断血瘀证统一标准区分为血瘀证和非血瘀证,分别计算舌下络脉的诊断敏感度、特异度、准确率和正确指数,并与传统瘀象舌进行对照,从而探讨舌下络脉对血瘀证的诊断价值。结果在上述三种疾病中,舌下络脉的病变程度与血瘀证有一定关联性,但无论以舌下络脉的哪一种变化程度作为判定标准用于诊断血瘀证,均不能同时获得较高的敏感度和特异度,其准确率亦不甚高,而其正确指数更低,与瘀象舌相比有着明显的差异。结论舌下络脉对于血瘀证具有一定的诊断参考意义,但其诊断价值与传统舌象有较大差异,尚不足以作为诊断血瘀证的重要依据。
Objective:To find out the diagnostic utility of sublingual veins for Blood-stasis Syndrome by means of diagnostic tests.Methods:The observation were carried out on patients with coronary heart disease,pulmonary cardiopathy and dysmenorrhea.The tried criterion in every test was respectively one of the three variation degrees of the sublingual veins,and the acknowledged standard of blood-stasis syndrome was taken as the golden standard.Then the data of sensitivity,specificity,accuracy and Youden's index in every test were worked out.A contrast was made between the method of observing sublingual veins and traditional tongue inspection as well.Results:For the patients with the above three kinds of diseases,there were some relation with the variance degrees of sublingual veins.However,the results of every test showed that any of the two data of sensitivity and specificity was valuable unless the other was worthless,and each of the accuracy and Youden's index was lower than that acquired form the test with traditional tongue inspection.Conclusion:Subilingual veins can be taken as an helpful sign for blood-stasis syndrome diagnosis,but it should not act as a useful enough sign in determining whether a patient suffers form blood-stasis syndrome or not.
