摘要:

[目的]探讨冠心病患者不同舌象特征的客观衡量指标与证候的关联性,与舌诊客观指标的临床辨证意义。[方法]以先进技术手段获取不同舌象舌体的图像与热图、表面津液和舌体血液血流灌注率,分析与证候的关系。比较分析了阴虚血瘀证、气虚血瘀证冠心病患者舌象对应的舌色度、津液、血流量、红外热图特征,探索分析客观反映不同证型冠心病患者舌象特征性因素间的关系。气虚血瘀组舌体血流灌注率低于其他两组。[结果]阴虚血瘀组舌色红(R)比最高,气虚血瘀组次之,各组舌体温度分布各不相同。舌津液比较中,以对照组舌表面津液量最大,阴虚血瘀组最小,对照组最高。[结论]不同证型冠心病患者舌体色度、温度与分布、血流灌注率及舌表面津液量具有不同表现规律,是舌象客观化研究的重要参数,有临床参考价值。

Abstract:

[Objective] To investigate the relationship between the picture of the tongue in patients with coronary artery disease (CAD) and the differentiation of symptoms and signs of Traditional Chinese Medicine (TCM). [Methods] The different picture of tongue and infrared chart, surface saliva, blood filling rate of tongue were observed by advanced technology and compared with the symptom of TCM. The yin asthenia syndrome of blood stasis (A) and deficiency of vital energy syndrome of blood stasis (B) of CAD patients were compared with the corresponding color of tongue, saliva, blood flow and characteristic of infrared chart. The filling rate of deficiency of vital energy syndrome of blood stasis group was significantly lower than that of other two groups. [Results] The color of tongue R was significantly increased in group A, that of B group was the next in order. The temperature distribution of tongues was different in those groups. The saliva was largest in control group and it was least in group A. [Conclusion] Each CAD patients have different characteristic of tongue such as color, temperature distribution, filling rate, saliva and so on. These characteristics are important parameters for objective study of the tongue and plays an important role in clinical work.
