红外热图技术与腰椎间盘突出症中医证型的相关性研究

Study on Relationship between Infrared Thermograph and Syndrome Types of Traditional Chinese Medicine in Lumbar Intervertebral Disc Herniation

目的:探讨红外热图技术与腰椎间盘突出症中医证型之间的关系。方法:针对患有腰椎间盘突出症的患者按照中医气滞血瘀型、湿热痰滞型、风寒湿滞型、肝肾亏虚型进行分类,分别选取50例,并相应选取各50例健康人群作对照。观察组与对照组的受检者均通过PFK-800医用红外热像仪进行扫描。扫描范围包括腰背部、股后区、小腿后区。并记录相同区域的两侧体表温度差值结果:1、中医各证型与对照组之间双下肢温度差异程度有显著性差异(P<0.01);而中医各证型之间双下肢温度差异程度均无显著性差异(P>0.05)。2、对照组中的健康人群双下肢温度高低不是非常明显。气滞血瘀型与湿热痰滞型患者的患侧温度要比对侧温度高;而风寒湿滞型与肝肾亏虚型患者的患侧温度要比对侧温度低。结论:1、通过红外热图技术结合相应的临床体征能够很好的对腰椎间盘突出症进行诊断(双下肢温度差异程度有显著性差异)。2、对于腰椎间盘突出症的患者,通过红外热图技术能够较为准确地判断出中医八纲辨证中的寒、热证型,为中医在辨证过程中判断寒、热证型提供了一个较为可靠的客观依据。

Objective： To investigate the relationship between infrared thermograph and syndrome types of traditional Chinese medicine （TCM） in lumbar intervertebral disc herniation （LIDH）. Methods： From September 2004 to August 2006, we collected 200 patients of LIDH, which respectively fell into 4 syndrome types of TCM： stagnation of vital energy and blood stasis, humid heat and phlegm stagnancy, stagnation of cold and dampness, and deficiency of liver and kidney, with each type 50 cases. Another 50 healthy people were enrolled as control group. All cases were scanned by PFK--800 medical in- frared thermograph. The scanning zone included low back, posterior regions of thigh and posterior crural region. The temperature difference between both sides around the same area was recorded. Results： 1. The temperature differences of both lower limbs in LIDH people were significantly obvious than those in control group （P〈0.01）, while no remarkable differences were found between each type of TCM syndrome （P〉0.05）. 2. The temperature fluctuations of both lower limbs in healthy people were insignificant. The temperature of the abnormal side was higher than normal side in patients of stagnation of vital energy and blood stasis type and humid heat and phlegm stagnancy type; whereas the temperature of the abnormal side was lower than normal side in patients of stagnation of cold and dampness type and deficiency of liver and kidney type. Conclusion： 1. Better diagnoses of LIDH can be made through combining infrared thermograph with clinical signs. 2. Scientific basis can be provided for the diagnosis of cold and heat syndromes in LIDH patients with the help of infrared thermograph.
