基于"玄府-气液-络脉"理论的结节性痒疹病机演变与分层治疗OA

Based on the Traditional Chinese Medicine(TCM)theory of"Xuanfu-Qiye-Luomai"this paper sys-tematically explores the etiology,pathogenesis,and treatment strategies for prurigo nodularis.The study identifies the core pathogenesis as the obstruction of Xuanfu,impaired distribution of Qiye,and stasis in the collaterals;these factors collectively constitute a complete pathological process progressing from the exterior to the interior and from functional impairment to structural change.Integrating literature analysis with clinical experience,the paper proposes treatment principles centered on"opening Xuanfu,regulating Qiye,and unblocking collaterals to resolve nodules".It details spe-cific therapeutic approaches:using wind-dispelling and bark-based herbs to open Xuanfu;employing Qi-regulating and diuresis promoting agents to facilitate the flow of Qiye;and utilizing blood-activating,phlegm-resolving,insect-derived,and vine-type herbs to deeply unblock collaterals and resolve nodules.Adopting a holistic perspective based on the"Xuanfu-Qiye-Luomai"framework,this study offers systematic TCM theoretical guidance and medication strat-egies for the clinical management of prurigo nodularis,a stubborn dermatological condition,thereby holding significant theoretical and clinical value.
