健康人十二经原穴血流量失衡度的初步观察

Preliminary Observation on Imbalance Degree of Blood Perfusion on the Twelve Yuan-source Points in Healthy Subjects

目的:测算健康人十二经原穴血流量及左右失衡度(IBD-LRM)、表里失衡度(IBD-EIM)、手足失衡度(IBD-HFM)的正常值范围,为经络诊断奠定基础。方法:使用激光多普勒线扫描仪(LDLS)测量31名受试者的十二经原穴血流量,计算十二经血流量的分布及IBD-LRM、IBD-EIM、IBD-HFM 3种失衡度。结果:(1)十二经原穴左右两侧血流量几乎相等,IBD-LRM总均值为(0.8±7.0)%;IBD-LRM绝对值介于(13.2±12.0)%至(22.9±15.6)%之间,最大绝对失衡度在胆经,总均值为(16.2±4.1)%。(2)6对表里经中有5对里经(阴经)血流量大于表经(阳经),IBD-EIM总均值为(-11.4±10.4)%,IBD-EIM绝对值在(16.6±12.1)%至(36.6±15.6)%之间,最大绝对失衡度为三焦-心包,总均值为(25.2±8.0)%。(3)6对手足同名经手经血流量均大于足经,IBD-HFM均值为(38.8±18.2)%,IBD-HFM绝对值在(34.4±20.9)%到(59.6±12.0)%之间,最大绝对失衡度为手足少阴经,总均值为(43.8±13.3)%。(4)3种失衡度绝对值的大小排列顺序与以往用经皮二氧化碳释放量(TCE)计算的3种失衡度相同,两指标的IBD-LRM绝对值接近,表里和手足失衡度的绝对值有一定差异。结论:健康人十二经原穴血流量的IBD-LRM较小,基本处于平衡状态,IBD-EIM和IBD-HFM较高。

Objective To lay a foundation for meridian diagnosis by measuring the blood perfusion （BP） on yuan-source points of twelve meridians and calculating the normal range of imbalance degree （IBD） of left and right meridian （IBD-LRM）, IBD of exterior-interior meridian （IBD-EIM） and IBD of hand-foot of the same name meridians （IBD-HFM） in healthy subjects. Methods BP at yuan-source points of twelve meridians was measured on 31 healthy volunteers by a Laser Doppler Line Scanner （LDLS）. BP distribution and IBD-LRM, IBD-EIM, IBD-HFM were calculated. Results （1） Of the twelve meridians, BP was almost equal between the left and right of the same meridian. The mean value of IBD-LRM was （0.8 ±7.0）%. The absolute value of IBD-LRM ranged from （ 13.2± 12.0） % to （22.9 ± 15.6） %, with the mean value of （ 16.2 ±4.1 ） %, the IBD of gallbladder meridian of foot-shaoyong was the highest. （2） Of the six pairs of exterior-interior meridians, five pairs manifested as the interior （yin） meridians being larger than the exterior （yang） meridians in BP. The mean value of IBD-EIM was （- 11.4±10.4）%. The absolute value of IBD-EIM ranged from （16.6--. 12.1）% to （36.6±15.6）% ,with the mean value of （25.2±8.0）%, the IBD between pericardium meridian of hand-jueyin and triple energizer meridian of hand-shaoyang was the highest. （3）All of the handfoot of the same name meridians were found hand meridians being larger than foot in BP. The mean value of IBD-HFM was （38.8 ±18.2） %. The absolute value of IBD-HFM ranged from （34.4 ±20.9） % to （59.6 ±12.0） %, with the mean value of （43.8 ±13.3） %, and IBD between heart meridian of hand-shaoyin and kidney meridian of foot-shaoyin was the highest. （4） The order of IBD absolute value in BP was the same as transcutaneous CO2 emission （TCE） measured before, and their IBD-LRM absolute values were close to each other. However, the absolute values of IBD-EIM and IBD-HFM existed some differences. Conclusion The IBD-LRM of the twelve yuan-source points in BP of healthy subjects is small and in a balance state, but IBD-EIM and IBD-HFM are relatively high.
