【摘要】：经络学说一直对中医各科的诊断与治疗有指导作用,是中医学的重要组成部分。中医经络的理论体系和判定完全不同于现代医学。从上世纪五六十年代始,人们一直试图获取更多的关于穴位和经络的物理存在以及运行机理的信息。另外,基于生物医学光子学的原理和测量技术,利用特定波长的激光在生物组织中的传输和分布特性,研究组织的光学特性以及和生理状态的关联。本工作应用自行搭建的一套漫射光自动测量系统,当光沿着特定组织的传播时,对生物组织表面的漫反射光的分布特性进行实时无损测量。通过测量人体经络区域的漫射光强度分布,获得不同组织的光学传输特性及其生理状态信息。运用808nm光波,全天候测量了小肠经、心经经络组织以及附近的非经络组织的光学传播特性,获得了时间周期下的人体经络及其周围组织表面的漫射光强度分布数据。通过对两组数据的比较和统计分析,在实验室测量环境相同的情况下,结果显示经络与非经络之间漫射光强度分布存在明显的差异性(P0.05),这种差异性的事实存在确实反映了人体组织中存在一种通路,体现出与周围组织不同的生理特性和反应,可能是经络客观存在的一种有效证据。同时组织的漫射光强度分布数据还呈现有时间的周期性,暗合中医经络理论中的经络气血运行的时间特性。例如,小肠经脉线及旁开非经脉测量结果表明,中午12：00时的小肠经上漫射光衰减明显快于其它时刻,与小肠经上之气血运行时间非常相关。这种关联对于经络气血运行和人体经络的客观存在有很强的参考价值。本工作还对该系统的稳定性、测量效率和测量精度,以及斩波器对光传输特性的影响进行了研究。
[Abstract]:Meridian theory has been guiding the diagnosis and treatment of traditional Chinese medicine and is an important part of traditional Chinese medicine.The theoretical system and judgment of meridian in TCM is completely different from modern medicine.Since the 1950s and 1960s, people have been trying to obtain more information about the physical existence and mechanism of acupoints and meridians.In addition, based on the principles and measurement techniques of biomedical photonics, the optical properties of the tissues and the correlation between the optical properties and the physiological states are studied by using the transmission and distribution characteristics of laser in biological tissues with specific wavelengths.In this work, an automatic measuring system of diffuse light is set up. When the light propagates along a particular tissue, the distribution of diffuse reflected light on the surface of biological tissue is measured in real time and nondestructive.The optical transmission characteristics and physiological state information of different tissues were obtained by measuring the intensity distribution of diffuse light in the meridian region of human body.The optical propagation characteristics of small intestine meridian, cardiac meridian and adjacent non-meridian tissues were measured by using 808nm light wave. The diffuse light intensity distribution data of human meridian and its surrounding tissues were obtained under the time cycle.Through the comparison and statistical analysis of the two groups of data, under the same environment of laboratory measurement,The results showed that there was a significant difference in the distribution of diffuse light intensity between meridian and non-meridian meridians. The existence of this difference reflected the existence of a pathway in human tissues, which reflected different physiological characteristics and responses from the surrounding tissues.It may be an effective evidence of the existence of meridians and collaterals.At the same time, the distribution data of diffuse light intensity also showed the periodicity of time, which was consistent with the time characteristic of meridian qi and blood running in the theory of meridian and collaterals of traditional Chinese medicine.For example, the measurement results of small intestine meridian line and non-meridian meridian show that the light attenuation of the upper diffuse light of the small intestine at 12:00 is much faster than that at other times, which is closely related to the running time of qi and blood on the small intestine meridian.This kind of correlation has very strong reference value for the movement of meridian qi and blood and the objective existence of human meridian.The stability, measurement efficiency and accuracy of the system and the influence of chopper on the optical transmission characteristics are also studied.
