Recur is the most important characteristic of psoriasis, this is not the case in the treatment of disease. TCM believes that " Fuxie " is an important reason for the recurrence of the disease, but also the entry point for treating disease. We "Fuxie 'departure that" hot evil volts in the kidney "is its long lasting pathogenesis. Relapse prevention or "recover from illness defense complex" is an important part of the treatment of disease. Consensus medicine can reduce disease recurrence, prolong remission, but the mechanism is not yet clear. Study confirmed helper T cell (Th) plays an important role in the development of the disease. We previously demonstrated based on the " Fuxie " theory Clearing away heat evil thoroughly nourishing kidney(Modified cooling Xiaofeng powder) is effective in treating psoriasis, but whether it can reduce relapse, by what mechanism to stabilize the disease is for further study. The topic for Th17, Treg and Th cells and other downstream cytokines using Real-time PCR 、liquid suspension array technology to randomized control principles for the treatment of patients with recurrent psoriasis vulgaris blood heat syndrome before and after the treatment of peripheral follow-up of patients blood testing, to explore methods to control the disease development Refreshing ney, to achieve and maintain a long remission of part of immunological mechanisms in order to provide new ideas and experimental basis for the treatment of psoriasis and "recover from illness defense complex" and thus clinical treatment and better services for patients.
易复发是银屑病最主要特征,此属中医治未病。中医认为“伏邪”是复发疾病的重要原因,也是治未病切入点。我们从“伏邪”出发认为“热邪伏于肾”是其久治不愈的病因病机。防复发即“瘥后防复”是治未病的重要部分。共识中药能减少此病复发、延长缓解期,但其机制尚不明。研究证实辅助性T细胞(Th)在此病发生发展中起重要作用。我们前期证实基于“伏邪”理论清透滋肾法加味凉血消风散能有效治疗银屑病, 但是否能降低复发,通过何机制去稳定病情是需进一步研究。本课题针对Th17、Treg等Th细胞及下游细胞因子采用Real-time PCR﹑液态悬浮芯片等技术,以随机对照原则,对复发性寻常型银屑病血热证患者治疗前后及治疗后随访患者外周血进行检测,探索清透滋肾法控制病情发展 ,达到并维持长时间缓解的部分免疫学作用机制,以期为银屑病的治疗及“瘥后防复”提供新的思路及试验依据,从而指导临床治疗,更好地为患者服务。
目的:本研究通过比较复发型寻常型银屑病血热证患者治疗前后、健康人、临床痊愈者外周血中辅助T细胞及其细胞因子、转录因子等的变化,以此为基础总结复发型寻常型银屑病血热证的部分特征,为寻常型银屑病血热证提供微观物质基础;同时探究加味凉血消风散治疗寻常型银屑病血热证的部分免疫学作用机制及作用靶点,总结银屑病易复发的免疫网络特点,为治疗寻常型银屑病的提供新思路。方法:排除数据缺失、病例脱落等因素后,符合标准的复发型寻常型银屑病血热证患者共40例,分为实验组、对照组,与临床痊愈者10例、健康者10例比。采集健康者、痊愈者、寻常型银屑病血热证患者血液,使用流式细胞术、Real-time PCR、Western Blot、液相悬浮芯片检测外周血中辅助T细胞(Th1、Th2、Th9、Treg、Th17、Th22)数量及分布,细胞因子、趋化因子、转录因子的基因或蛋白水平,同时观察两组患者治疗前后各项指标变化,并记录PASI、BSA、瘙痒程度评分、DQOLS。最终对数据进行统计学分析。结果:与健康者、痊愈者相比,在复发型寻常型银屑病(血热证)患者中高表达(P <0.05)的辅助T细胞、细胞因子、趋化因子及相关转录因子基因、蛋白有:Th1、Th9、Th17、Th22、IL-2、IL-6、IL-8、IL-10、IL-12、IL-17、IL-21、IL-23、IFN-γ、TNF-α、MIP-1α、MIP-3α、RORγt、T-bet;低表达(P <0.05)的有:Th2、Treg、GATA-3、Foxp3;无明显差异的有:Th2、IL-4、IL-5、IL-13、IL-1β、ITAC、MIP-1β。此可能为血热证辩证依据。加味凉血消风散可能通过上调Treg、GATA-3、Foxp3,下调Th1、Th9、Th17、Th22、IL-2、IL-6、IL-8、IL-12、IL-17、IL-21、IL-23、IFN-γ、TNF-α、MIP-1α、MIP-3α、RORγt、T-bet水平发挥治疗血热证寻常型银屑病的作用。在治疗后患者体内相对于健康人、痊愈1年者仍呈现高表达,提示可能与银屑病复发相关的因素有:IFN-γ、IL-12、IL-2、TNF-α、IL-8。与PASI评分呈正相关(P<0.05)的有:TNF-α、IL-8。取得成果:培养硕士研究生5名,已发表文章2篇,正撰写的文章5篇,拟发表文章7篇。
