Abstract： 目的研究血管内皮生长因子(VEGF)及其受体在银屑病皮损中的表达.方法采用原位杂交和免疫组化SABC法,检测42例寻常性银屑病患者皮损和15例正常人皮肤组织VEGF mRNA和其蛋白、VEGF受体2(KDR蛋白)、微血管密度(MVD),分析其表达情况.采用双抗体夹心酶联免疫吸附法检测患者和正常人血清中VEGF水平.结果①寻常性银屑病患者皮损处的VEGF mRNA及其蛋白、KDR和MVD表达明显强于正常人对照组(P＜0.001);皮损处与非皮损组相比,VEGFmRNA和其蛋白的表达差异无统计学意义,但KDR、MVD的表达差异有统计学意义;进行期与静止期比较四者差异均有统计学意义.②高密度组(MVD≥17.88)与低密度组(MVD＜17.88)的VEGF mRNA及其蛋白表达差异无统计学意义,但KDR表达差异有统计学意义(P＜0.01),且PASI评分差异也有统计学意义(P＜0.001).③患者血清中VEGF水平明显高于正常人对照组.结论①VEGF及其受体在银屑病新生血管形成中起重要作用.②MVD值可反映寻常性银屑病的严重程度,可作为判断病情和预后的指标.
