简介：摘要目的探讨孟鲁司特对儿童过敏性紫癜Toll样受体表达的影响。方法将86例过敏性紫癜患儿分为治疗组和对照组，每组43例。对照组采用的是常规综合治疗的方法，治疗组在与对照组基础上加用孟鲁司特。实时荧光定量PCR技术检测外周血单核细胞中TLR2、TLR5及TLR9mRNA的基因相对表达量。结果治疗组和对照组治疗后与治疗前相比，外周血单核细胞TLR2、TLR5及TLR9mRNA相对表达量均显著降低（均为P＜0.05），且治疗后治疗组外周血单核细胞TLR2、TLR5及TLR9mRNA相对表达量均明显低于对照组（均为P＜0.05）。结论孟鲁司特能影响过敏性紫癜患儿Toll样受体（TLR2、TLR5及TLR9）的蛋白表达，提示TLR2、TLR5及TLR9活化可能参与了过敏性紫癜的免疫发病机制。

简介：目的：研究CD14＋单核细胞Toll样受体（TLRs）表达在复发性生殖器疱疹疾病中的表现。方法：本组抽取我院于2011年11月至2013年11月收治的复发性生殖器疱疹患者35例作为观察组,取同期入院体检正常的30例作为对照组,分析两组患者TLRs受体表达情况。结果：观察组患者的外周血单核细胞TLR4、TLR8、TLR9分别为（38.84±23.19）、（94.26±4.63）、（96.93±4.39）,对照组患者的外周血单核细胞TLR4、TLR8、TLR9分别为（19.73±8.68）、（101.68±5.17）、（97.06±4.22）,其中观察组的TLR4、TLR8与对照组存在显著差异,差异具有统计学意义（P〈0.05）。两组患者的外周血单核细胞TLR9无明显差异,不具统计学意义（P〉0.05）。复发次数≥6次/年与复发次数〈6次/年患者的复发性生殖器疱疹患者外周血单核细胞TLR4、TLR8、TLR9之间无显著差异,不具统计学意义（P〉0.05）。结论：复发性生殖器疱疹患者发病期间,单核细胞TLR4、TLR8的增强能够提高免疫细胞抗病毒作用。
