简介:目的:检测梅毒血清固定患者外周血Th9细胞的表达水平,探讨其与血清固定免疫机制的关系。方法:收集梅毒血清固定患者(15例)、正规驱梅治疗后血清转阴者(8例)及正常对照者(15例)外周血单个核细胞,采用流式细胞仪检测Th9细胞比例。结果:血清固定组Th9细胞比例较血清转阴组和正常对照组降低,差异有统计学意义(Z=-3.49,P〈0.001;Z=-3.40,P=0.001);血清转阴组Th9细胞比例较正常对照组稍高,但差异元统计学意义(Z=-1.03,P=0.301)。结论:Th9细胞可能通过一系列免疫过程参与了血清固定的发生发展,具体机制仍有待进一步明确。

简介:目的比较新疆地区寻常型银屑病患者皮损及正常人群皮肤中干扰素伽玛诱导的单核细胞因子(CXCL9)的表达差异。方法Envision免疫组织化学法(IHC)检测新疆寻常型银屑病患者皮损及正常人皮肤中CXCL9的表达情况。结果与正常皮肤组织相比,CXCL9在寻常型银屑病皮损中的表达明显增加,主要以真皮乳头顶端为主,且差异具有明显统计学意义(χ2=34.80,P〈0.01);新疆地区汉族寻常型银屑病患者和维吾尔族寻常型银屑病患者皮肤组织中CXCL9的表达差异无统计学意义(χ2=1.64,P〉0.05)。结论新疆寻常型银屑病患者皮损中CXCL9的表达升高,通过JAK/STAT信号通路在寻常型银屑病的炎症反应中发挥重要作用;但汉族和维吾尔族寻常型银屑病患者皮损中CXCL9的表达相似。

简介:目的探讨IL-17和IL-6在白癜风患者外周血中的变化及临床意义。方法酶联免疫吸附试验法检测60例白癜风患者和30例正常对照者外周血中IL-17和IL-6的表达水平。结果(1)寻常型白癜风患者组外周血中IL-17和IL-6水平均显著高于对照组(P〈0.01)。(2)节段型白癜风患者组外周血中IL-17和IL-6水平与正常对照组相比差异无统计学意义(P〉0.05)。(3)寻常型白癜风患者组中,进展期患者外周血IL-17水平显著高于稳定期患者(P〈0.01)。结论IL-17和IL-6可能在白癜风的发病机制中发挥重要作用;IL-17与寻常型白癜风的活动性有关。
简介:表皮松解性掌跖角化症(EPPK)是一种通常由位于17q12染色体上KRT9突变导致的常染色体显性遗传性皮肤病。本文综述了目前为止,EPPK家系中KRT9突变的类型及特点。通常认为KRT9基因突变热区位于螺旋结构的杆状功能域1A区和2B区。随着EPPK家系病例的不断积累,在K9的头部也已检出突变位点,不再局限于螺旋结构杆状结构域。

简介:目的:探讨卵巢高分化黏液性癌(highlydifferentiatedOvarianmucinouscarcinoma,HDOMC)患者中MMP-2、MMP-9、S100A14的表达水平及意义。方法:采用免疫组化法对40例正常卵巢组织、43例卵巢黏液性肿瘤(Ovarianmucinoustumor,OMT)、80例HDOMC患者中MMP-2、MMP-9、S100A14的表达水平进行检测,并分析HDOMC患者中S100A14表达与MMP-2、MMP-9表达的相关性。结果:MMP-2、MMP-9、S100A14在正常卵巢组织、OMT、HDOMC患者中的表达水平呈递增趋势,且两两组间比较差异显著(P〈0.05)。Spearman相关分析:HDOMC患者中S100A14表达与MMP-2、MMP-9表达水平两两呈正相关(P〈0.05)。MMP-2、MMP-9、S100A14表达水平与HDOMC患者手术-病理分期(FIGO)、CA-125水平有关(P〈0.05);与年龄、肿瘤直径、淋巴结转移无关(P〉0.05)。结论:MMP-2、MMP-9、S100A14表达水平升高与HDOMC发生、进展、早期转移具有显著相关性,早期联合筛查这些指标对HDOMC病情演变及治疗预后评估具有重要价值。
