从“邪伏于络”论治儿童过敏性紫癜

Treatment of Pediatric Allergic Purpura from the Perspective of “Latent Pathogens Lodging in the Collaterals”

摘要: 文章以《内经》络病理论为基础，阐述了过敏性紫癜的基本病位在于血络，而风、热、湿、毒、虚、瘀则是重要的病因和病理环节，其病机为伏邪潜内，新感触发，络脉受损。治疗上则采取通补兼施，佐以活血化瘀通络，早期以祛邪通络为主，辅以祛风、清热、解毒、除湿，驱邪外出，条达脉络；迁延期以扶正养络为主，固本以防伏邪再生。

Abstract: Based on the collateral disease theory in The Inner Canon of Huangdi, this article elucidates that the primary pathological location of allergic purpura lies in the blood collaterals. Wind, heat, dampness, toxins, deficiency, and blood stasis are key etiological factors and pathological links. The disease mechanism involves latent pathogens residing internally, triggered by new exogenous factors, leading to collateral damage. The treatment principle emphasizes both unblocking and tonifying, supplemented by activating blood circulation, resolving stasis, and dredging the collaterals. In the early stage, the focus is on eliminating pathogens and unblocking collaterals, assisted by dispelling wind, clearing heat, detoxifying, and removing dampness to expel pathogens and regulate the collaterals. During the prolonged phase, the strategy shifts to supporting healthy qi and nourishing the collaterals, reinforcing the root to prevent the recurrence of latent pathogens.
