RESUMO
Objective:To observe the impact of compound glycyrrhizin combined with triamcinolone acetonide on clinical effects and immune function in the patients with oral lichen planus ( OLP) . Methods:Totally 100 patients with OLP were randomly divided into the control group (50 cases) and the study group (50 cases). The control group was locally injected with triamcinolone acetonide, and the study group was treated with compound glycyrrhizin tablets additionally. The treatment course was 4 weeks. Visual analogue scale ( VAS) and REU scoring system were used to assess pain and symptoms of OLP, the clinical effects and cellular immune function were compared, and the adverse reactions were recorded as well. Results:After the treatment, the VAS score and REU score respec-tively lower than those for the control group, and there were differents between the two groups (P<0. 05). The total effective rate was 84. 0% in the study group, which was higher than that in the control group (66. 0%) (P<0. 05). The percentage of CD3+ and CD4+ cells was increased, that of CD19+ cells and the ratio of CD4+/CD8+ were decreased, and there were significant differences be-tween the two groups (P<0. 05). The adverse reactions in both groups were mild. Conclusion:Compound glycyrrhizin combined with triamcinolone acetonide is effective for OLP and can improve the immune function in the patients.
