Clinical Trial Summary

Oral lichen planus (OLP) is a common chronic inflammatory disease of Oral mucosa. The pathogenesis of OLP is not clear, and there is no effective method to cure it. In vitro, previous studies have shown that oral mucosal mesenchymal stem cell cells (MSCs) can secrete Ido, which is involved in the pathogenesis of OLP. It has been proved that mental disorders such as depression and anxiety play an important role in the pathogenesis and treatment of OLP. Mental stress factors can cause abnormal changes of inflammatory factors, leading to immune dysfunction, which is also one of the main causes of OLP. In this study, we integrated the advantages of stomatology, psychiatry, neurobiology and traditional Chinese medicine, focused on the clinical problems of mental disorders with oral mucosal comorbidity, and assessed the depressive and anxiety status of OLP patients, so as to improve the therapeutic effect of OLP.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The scores of the scale with the symptoms and signs of the disease	Psychological factors in OLP patients and normal controls were assessed using psychological scales such as the Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD). Tissue and blood samples were collected during visits, and the concentrations of inflammatory factors in normal and lesion tissues were detected using immunofluorescence, flow cytometry, and enzyme-linked immunosorbent assay (ELISA). Statistical analysis was performed to determine the correlation between emotional disorders and inflammation in OLP patients, aiming to elucidate the underlying pathogenic mechanisms.	During the initial diagnosis,through study completion, an average of 1 year
