The famous national practitioner of Traditional Chinese Medicine with plentiful experience in clinical practice in our university did the research systematically on the Traditional Chinese Medicine theorem of the detoxification of Psoriasis vulgaris and furthermore suggested the perception of Traditional Chinese medicine psoriasis No.1 according to the unique 'Linnan' geographic location. This therapy has been applied clinically for a few years and it is proved to be effective in clinical treatment. Based on the pervious study, we address the presumption that Traditional Chinese medicine psoriasis No.1 balanced the NE and trappin-2 by adjusting the secretion of NE from neutrophil and also modifying the trappin-2 inhibitor which affect the NE. Hence the inflammatory response can be curled and cell proliferation can be declined. This project consists of three parts:1.the effect of Traditional Chinese Medicine No. 1 on the secretion of inflammatory factor such as NE, trappin-2 in the model of Peripheral Blood (PB), Neutrophil and Psoriasis Transmembrane; 2. The improvement of Psoriasis inflammatory response and the interposition of Psoriasis No.1 by NE and trappin-2;3.The adjustment of HaCat cell proliferation and the interposition of Psoriasis No.1 by NE and trappin-2.We aim to deduce the internal structure of the effectiveness of the detoxification treatment of Psoriasis vulgaris so that we can provide the sufficient scientific proof of the treatment of Psoriasis vulgaris using Traditional Chinese medicine and develop the modern Tradition Chinese Medicine therapy.
我校国家级名老中医多年的临床实践,结合岭南的独特地理位置,对"从毒论治"寻常型银屑病进行了系统的中医理论探讨,并拟定了中药复方银屑1号。多年临床应用,疗效确切。在前期实验研究基础上,我们提出假说:中药复方银屑1号可能通过调节中性粒细胞分泌的NE以及调控NE的抑制剂trappin-2,保持两者的平衡,进而调控银屑病的炎症反应,减少角质形成细胞的增生,从而达到治疗作用。本研究方案分三部分验证假说:1.中药复方银屑1号对外周血、中性粒细胞及银屑病跨膜模型中NE、trappin-2等炎症因子分泌的影响;2.NE、trappin-2对银屑病炎症的调控及银屑1号的干预;3.NE、trappin-2对HaCat细胞增殖的调控及银屑1号的干预。阐明"从毒论治"寻常型银屑病的作用的内在物质基础,为确立中药复方治疗寻常型银屑病新的作用靶点提供更充分的科学依据,为中药复方的现代化与推广提供强有力支持。
银屑病是皮肤科多发病、疑难病。中医药治疗疗效显著,有其独特的理论基础。我科结合岭南的独特地理位置,系统阐述了“从毒论治”,并在其基础上拟定了中药银屑1号方。从三方面验证假说:第一部分:中药银屑1号对外周血、中性粒细胞(PMNs)及银屑病跨膜模型中NE、trappin-2等炎症因子分泌的影响:第二部分:NE、trappin-2对银屑病炎症的调控及中药复发的干预:第三部分:NE、trappin-2对HaCat细胞增殖的调控及中药复方的干预。前期多年临床研究,疗效确切,副作用小。为进一步研究其作用机制,制备中药银屑1号的含药血清。结果:1、体外培养的PMNs、银屑病跨膜模型中:Elisa检测NE、trappin-2:生理盐水组表达水平最高,原液中药组表达水平最低。随着中药含药血清浓度的降低,表达水平逐渐升高。HaCat细胞的rt-qPCR结果:各中药组NE基因表达低于空白组,NE+1/3中药组基因表达低于NE组,表明加入中药后能有效降低NE基因表达;1/3中药组基因表达高于NE+1/3中药组,则进一步证明中药复方降低了NE的表达,控制炎症细胞的浸润。trappin-2方面:各中药组trappin-2基因表达均低于空白组,1/3中药组、trappin-2组均高于trappin-2+1/3中药组,证明中药复方可以降低trappin-2基因表达。中药复方可以同时降低HaCat细胞中NE及其内源性抑制剂trappin-2的基因表达,使两者水平达到动态平衡。2、细胞因子网络:不同浓度的中药含药血清不同程度降低了IL-6、IL-8、IFN-γ、TNF-α、Sicma-1的表达。3、中药银屑1号对HaCat细胞增殖的影响:24h时间点原液中药抑制率最高,且随着中药浓度的降低抑制率逐渐降低。表明中药复方可以明显抑制HaCat细胞增殖。综合实验结果推测:中药银屑1号可能通过降低体外培养PMNs、HaCat、银屑病跨膜模型中NE的表达,调节了其内源性抑制剂trappin-2的水平,从而使NE/trappin-2之间达到动态的平衡;且调节了多种细胞因子的水平,从而抑制了炎症反应;同时抑制了HaCat细胞的增殖,达到治疗作用。该研究可能为阐明中药复方治疗银屑病的内在物质基础,为确立中药复方治疗银屑病新的作用靶点提供更充分的科学依据,为建立中药复方的新的治疗手段提供重要的实验依据。
