摘要
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.
