体表络脉是观察人体健康和疾病状况的窗口

Collateral Veins in the Body Surface are Observation Windows to Detect Human Health and Disease Status

络脉是气血运行的通道,也是病邪传入通道和病变部位。部分络脉在体表可见,其变化可反映人体气血阴阳和寒热虚实状态,也是观察人体健康和疾病状态的窗口。中医师通过观察皮肤、舌下、视网膜、虹膜、巩膜、结膜等部位络脉了解病情,糖尿病、高血压、动脉硬化等病患者在这些部位的络脉则发生明显变化。与肉眼观察相比较,用放大镜、显微镜等手段能大大提高我们的观察能力,能清晰观察到肉眼看不到的内容,更早、更准确地为我们提供疾病信息,其可作为体检、诊断的依据。

Collateral veins are special channels of Qi and blood. But it is also the gateway of pathogenic factors that lead to its pathological changes. Parts of the collateral veins can be visual observed in the body surface. Its changes re- fleet different human body status and the changes of Qi, blood, Yin, Yang, etc （ The terminology of traditional Chinese medicine）. So, collateral veins in the body surface are observation windows to detect human health and disease status. Traditional Chinese doctors observe the change of the collateral veins to find out patients＂ condition at the place of skin, sublingual, retina, iris, sclera and conjunctiva. Significant change can be seen in patients of diabetes ; high blood pres- sure and atherosclerosis, etc. Compared with visual observe, a magnifier or a microscope can greatly improve our obser- vation ability, which can show the change in the collateral veins more clearly and some changes we cant see with eyes. It can provide information about patients＇condition earlier and more accurate. So using a magnifier or a microscope to ob- serve the change of collateral veins can be a basis in a medical inspection.
