Abstract:
Objective To assay the salivary ANG-2 level of oral lichen planus(OLP)patients,and analyze its correlation with in-flammatory activity of OLP.Methods Eighty-nine OLP patients were included,and divided into four subgroups as non-erosive asymp-tomatic(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 base-lines 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 sali-vary ANG-2 level and inflammation activity in OLP patients(r=0.314,P=0.003).The expression of ANG-2 in non-erosive OLP mu-cosal 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 sali-vary 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-inva-sive method.
