Abstract:
Hepatolenticular degeneration（HLD），also known as Wilson disease （WD）， is a genetic disorder characterized by copper metabolism disorder caused by ATP7B gene mutation. Specifically， due to the ceruloplasmin synthesis disorder induced by gene mutation，copper cannot be excreted through bile，which results in pathological deposition of copper in various organs and damage to organs such as the brain and the liver. The incidence of WD in Chinese is significantly higher than that in the world. Copper chelating agents， such as D-penicillamine and dimercaptosuccinic acid， are used as the main therapeutic agents in western medicine. However， many clinical adverse events limit the application of these drugs. Traditional Chinese medicine （TCM） has its characteristics in the treatment of WD. As confirmed by long-term research on TCM clinical diagnosis and treatment，MD has become TCM dominant disease. In spite of many views about the etiology and pathogenesis of WD，a consensus has not been reached so far. Based on the theory of latent pathogen in TCM and the pathological mechanism of excessive deposition of copper ions in the body，this study proposed that latent toxin is the key etiology of WD，and further elaborated that the latent toxin of WD was inherited from parents and occurred in children and adolescents，which was hidden in the liver and the kidney and damaged the brain. The latent toxin， Yang in nature and dispersing in property， is prone to transform into dampness-heat to block Qi movement and produce phlegm leading to stasis. Furthermore， this study determined latent toxin blocking collaterals as the basic pathogenesis of WD and revealed the complex clinical manifestations of latent toxin blocking collaterals such as liver collaterals，brain collaterals，kidney collaterals，spleen collaterals，stomach collaterals，lung collaterals，heart collaterals， and uterus collaterals. Treatment should follow the basic therapeutic principles of resolving pathogens，removing toxins， and dredging collaterals. This study is expected to provide a theoretical basis for syndrome differentiation and treatment of WD in TCM.
