中文摘要：

目的探索痰凝血瘀舌、气虚血瘀舌与舌血流的关系。方法运用彩色多普勒血流仪分别对41例痰凝血瘀舌、40例气虚血瘀舌及43例正常舌舌深动脉及舌深静脉进行彩色多普勒血流显像的检测，同时进行对照分析。结果在舌深动脉最大流速、最小流速、平均流速、阻力指数、搏动指数方面的比较差异均有统计学意义（P〈0．05或P〈0．01）。瘀血舌组表现为流速降低，阻力指数、搏动指数均增高，测及高阻力、低流速血流。结论气虚血瘀舌舌深动脉搏动指数明显低于痰凝血瘀舌，二者血流流速均低于正常舌。舌微循环障碍可能是瘀血舌形成的主要因素之一。

英文摘要：

Objective To study the relation between tongue blood flow and tongue of phlegm retention with blood stasis and tongue of qi deficiency with blood stasis. Methods The colored Doppler flow imaging （CDFI） was applied to test the blood flow of deep artery and vein of tongues of 41 phlegm retention with blood stasis patients, 40 qi deficiency with blood stasis patients, and 43 normal people for the comparison analysis. Results There was a significant difference in the maximum flow speed, minimum flow speed, av erage flow speed, resistance index, and throbbing index of deep artery of tongue （P〈0.05, P〈0.01）. The group of blood stasis tongue was manifested as decreased blood flow speed, increased resistance index and throbbing index, thus there was a high resistance and low speed of blood flow. Conclusion The throbbing index of deep artery of tongue of Qi deficiency with blood stasis group was lower than that of tongue of phlegm retention with blood stasis group, and the blood flow speed of these two groups was lower than one of the important factors in forming the blood stasis tongue.
