中文摘要：

银屑病是临床最常见的具有基因相关性的皮肤疾病之一。中医治疗具有疗效高同时不良反应小的特点，提示我们需要对其临床辨证论治规律进行研究。本文通过总结当代著名中医皮科专家治疗银屑病的辨证特点及用药规律，在银屑病“从血论治”的基础上提出“血分蕴毒”是银屑病的重要病机，其病位在“血”，病性为“毒”与“热”。并通过现代医学的视角，探讨“血分蕴毒”与现代医学的关系，这一认识丰富和发展了银屑病“从血论治”理论。

英文摘要：

Psoriasis is one of the most common and gene-related human skin diseases. Traditional Chinese medical therapy has curative effect with fewer side effects, so the investigation of the rules of TCM differentiation and pharmacological treatment in psoriasis would provide us a new approach to improve its clinical practice. By document analysis, we proposed a hypothesis that the pathogenesis of psoriasis-＇ toxin accumulation in blood＇ means the disease happened in blood and its characteristic was ＇toxin coming from excessive heat＇. In addition, we elucidated the meaning of ＇ toxin accumulation in blood＇ in the view of modern medicine, which might develop the TCM theory of ＇ treating psoriasis by modulating blood＇.
