络病理论及其在顽固性皮肤病中的应用

Collateral Disease Theory and Its Application in Intractable Skin Diseases

摘要: 络脉从经脉别出，纵横交错，遍布全身，可以沟通表里、渗灌气血，发挥“行气血而营阴阳”的生理功能，病邪侵袭络脉，导致络脉结构功能的受损，进而引起继发性脏腑组织病理改变形成络病。皮部既是经脉通行部位，也是最大的络脉分布场所，皮部为身体的外在表达部位，能通过络脉的传导反映体内五脏六腑的变化，故皮肤病的病理基础与络病理论密切相关。本文基于络病理论对皮肤病的病机与证治进行探讨，从而更好地理解其内涵和运用要点，为临床应用提供参考。

Abstract: The collateral vessels branch off from the meridians, crisscrossing and permeating throughout the body. They facilitate the circulation of qi and blood, nourishing yin and yang, and perform the physiological function of “circulating qi and blood to nourish yin and yang”. Pathogenic factors invading the collateral vessels can impair their structure and function, leading to secondary pathological changes in the viscera and tissues, resulting in collateral disease. The skin, being both the pathway for meridians and the largest distribution site of collateral vessels, serves as the external manifestation of the body. It can reflect changes in the internal organs through the conduction of collateral vessels. Therefore, the pathological basis of dermatological diseases is closely related to the theory of collateral disease. This article explores the pathogenesis, symptoms, and treatment of dermatological diseases based on the theory of collateral disease, aiming to enhance understanding of its essence and key application points, thereby providing a reference for clinical practice.
