The theory of traditional Chinese medicine believes that meridian-collateral (jingluo) is an important system to maintain life and participates in the formation and cure of disease. Exploring the biological connotation of meridian-collateral is the key content in the modern research of traditional Chinese meridian. For more than 60 years, scholars at home and abroad have carried out the researches of meridian-collateral from the fields of biomedicine (e.g. physiology, anatomy and histomorphology), imaging, physics, chemistry, computer technology, etc. Meridian-collateral research in modern times demonstrates a multi-disciplinary historical development and provides multi-perspective scientific information for understanding meridian-collateral. The meridian-collateral research in future needs more accurate multidisciplinary intersection, which will be the light of hope to reveal the biological connotation of meridian-collateral.
中医理论认为，经络是维持生命并参与疾病形成和治愈的重要系统。揭示经络的生物学内涵是现代中医研究的重要内容。60多年来，国内外学者从生物医学(生理、解剖、组织形态等)、影像学、物理、化学、计算机技术等领域对经络展开了研究。现代经络研究就是一部多学科交叉的历史，为认识经络提供了多视角的科学资料。未来经络研究需要更精准的多学科交叉，它将是揭示经络生物学内涵的希望之光。.
