摘要:

目的 检测口腔扁平苔藓(oral lichen planus,OLP)患者的血管生成素-2(angiopoietin 2,ANG-2)唾液浓度,分析其与OLP炎症活跃程度的关联性。方法 纳入89例OLP患者,分为无症状非糜烂型组、有症状非糜烂型组、轻中度糜烂型组及重度糜烂型组,15名健康成人作为正常对照组。收集受试者非刺激性全唾液,采用化学发光免疫法检测ANG-2浓度并进行分析。收集正常口腔黏膜组织和非糜烂型、糜烂型OLP口腔黏膜组织,采用免疫组化染色检测间质血管ANG-2表达。结果 与正常对照组相比,OLP组年龄和性别均无统计学差异,OLP全组及非糜烂型、糜烂型OLP组的唾液ANG-2浓度均显著增高(P<0.05);其中,糜烂型OLP组显著高于非糜烂型(P=0.022),有症状非糜烂型组高于无症状非糜烂型组(P=0.048),糜烂型亚组之间无统计学差异(P=0.067)。Spearman相关性分析显示,唾液ANG-2浓度与OLP患者炎症活跃程度呈正相关(r=0.314,P=0.003)。非糜烂型OLP间质血管的ANG-2表达较正常黏膜组织增加,但无统计学意义(P>0.05);糜烂型OLP间质血管ANG-2表达较正常黏膜组织(P<0.001)及非糜烂型OLP(P<0.001)均显著增加。结论 唾液ANG-2浓度与OLP炎症活跃程度有较高关联性,提示其可作为OLP炎症活跃标志物之一,辅助临床无创监测OLP病情变化。

Abstract:

Objective To assay the salivary ANG-2 level of oral lichen planus (OLP) patients, and analyze its correlation with inflammatory activity of OLP. Methods Eighty-nine OLP patients were included, and divided into four subgroups as non-erosive asymptomatic (NEA), non-erosive symptomatic (NES), minor-erosive (MIE) and major-erosive (MAE) groups. Fifteen healthy adults were recruited as controls. Whole unstimulated saliva was collected from each participant, and the salivary ANG-2 level was measured by chemiluminescence immunoassays (CLIA) for analysis. Normal oral mucosal tissue, non-erosive and erosive OLP tissues were collected to detect and analyze the expression of ANG-2 positive blood vessels by immunohistochemistry (IHC). Results The baselines of age and gender between OLP and control groups showed no significant difference. Compared to controls, the salivary ANG-2 levels of OLP group, non-erosive and erosive OLP subgroups were significantly higher (P<0.05), in which erosive OLP group was higher than non-erosive OLP group (P=0.022); NES subgroup was slightly higher than NEA (P=0.048), and there was no statistical significance between MIA and MEA subgroups (P=0.067). Spearman correlation analysis showed a positive correlation between salivary ANG-2 level and inflammation activity in OLP patients (r=0.314,P=0.003). The expression of ANG-2 in non-erosive OLP mucosal tissues slightly increased than normal oral mucosal tissue (P>0.05), but there was no significant difference. The expression of ANG-2 in erosive OLP mucosal tissues significantly increased than normal oral mucosal tissue (P<0.001) and non-erosive OLP group (P<0.001). Conclusion There is a certain correlation between salivary ANG-2 level and inflammatory activity of OLP, indicating that salivary ANG-2 level is probable to be one of the inflammatory activity indicators to monitor the state-variation of OLP as a clinical non-invasive method.
