摘要: 目的:探讨miR-146a在口腔扁平苔藓患者外周血及组织中表达及意义。方法:选取93例口腔扁平苔藓患者(OLP),包括非糜烂型53例和糜烂型40例,同期,选取健康者42例,利用反转录实时定量PCR(RT-qPCR)技术检测OLP患者外周血及组织中miR-146a、IRAK1和TRAF6表达,Pearson相关分析分析miR-146a与IRAK1和TRAF6表达相关性。结果:miR-146a在OLP患者血浆和组织中相对表达量均高于健康者,IRAK1 mRNA和TRAF6 mRNA在OLP患者血浆和组织中相对表达量均低于健康者,差异均有统计学意义(P<0.05);糜烂型OLP患者血浆和组织中miR-146a相对表达量均高于非糜烂型OLP患者,而IRAK1 mRNA和TRAF6 mRNA相对表达量均低于非糜烂型OLP患者,差异均有统计学意义(P<0.05);Pearson相关分析显示,OLP患者血浆和组织中miR-146a相对表达量均与IRAK1 mRNA和TRAF6 mRNA相对表达量呈负相关(r=-0.358、-0.345和-0.312、-0.379,P<0.05)。结论:miR-146a在OLP患者外周血及组织中呈高表达,且与病损程度有关,推测可能通过抑制IRAK1和TRAF6而发挥负调控作用参与OLP免疫炎性反应。

Abstract: Objective: To investigate the expression of miR-146a in peripheral blood and tissues of patients with oral lichen planus. Methods: Ninety-three patients with orallichen planus (OLP) were selected, including 53 cases of non-erosive type and 40 cases of erosive type. The expressions of miR-146a, IRAK1 and TRAF6 in peripheral blood and tissues were detected using real-time quantitative reverse transcription PCR (RT-qPCR). The correlations between expressions of miR-146a, IRAK1 and TRAF6 were analyzed using Pearson correlation analysis. Results: The relative expression levels of miR-146a in plasma and tissues of OLP were higher than those in healthy persons, while the relative expression levels of IRAK1 mRNA and TRAF6 mRNA in plasma and tissues of OLP were lower than those in healthy persons, and the differences were statistically significant (P<0.05). The relative expression levels of miR-146a in plasma and tissues of erosive type OLP were higher than those in non-erosive type OLP, while the relative expression levels of IRAK1 mRNA and TRAF6 mRNA were lower than those in non-erosive type OLP, and the differences were statistically significant (P<0.05). Conclusion: The expressions of miR-146a in peripheral blood and tissues of OLP were related with the degree of the lesion. It might be involved in OLP immune inflammatory response through repressing IRAK1 and TRAF6.
