Research Status on T-cell Phenotypes and Immunopathological Heterogeneity in Oral Lichen Planus Qizhan Sun, Yufeng Wang 2025, 28(6):  384-392.  DOI: 10.12337/zgkqjxjyzz.2025.06.002 Abstract ( 45 )   PDF (1870KB) ( 13 )   Oral lichen planus (OLP) is a chronic T cell-mediated autoimmune disorder of the oral mucosa. This review delineates the immunopathological mechanisms underlying OLP, focusing on the core pathway that progresses from an imbalance in CD4+ T-cell subsets to CD8+ T-cell-mediated tissue injury, a process further corroborated by pharmacological evidence. Studies have revealed heterogeneous infiltration patterns of CD4+ T-cell subsets (e.g., Th1, Th2, Th17, Treg) within the lesions of OLP patients, which closely correlate with clinical presentation and disease severity. Consequently, precise immunophenotyping of CD4+ T-cell infiltration holds promise for informing future individualized therapeutic strategies for OLP. References | Related Articles | Metrics

Investigation and Analysis on HIV/AIDS-related Knowledge and Attitudes of Dentists in Xinjiang and Beijing-Tianjin-Hebei Region Yan Shi, Di Le, Haixia Xing 2025, 28(6):  405-412.  DOI: 10.12337/zgkqjxjyzz.2025.06.005 Abstract ( 37 )   PDF (1787KB) ( 11 )   Objective: To assess regional differences in HIV/AIDS-related knowledge, attitudes toward patients with HIV/AIDS, and factors associated with treatment willingness among dentists in Xinjiang and the Beijing-Tianjin-Hebei region. Material and Methods: A cross-sectional questionnaire survey was conducted, including demographic characteristics, HIV/AIDS-related knowledge, attitudes, and treatment willingness towards patients with HIV/AIDS. Chi-square tests were used for group comparisons, and logistic regression was performed to identify factors influencing treatment willingness. Results: A total of 479 valid questionnaires were collected, including 165 males (34.4%) and 314 females (65.5%). Overall, 79.3% of dentists could correctly answer at least 10 questions among the 12 questions related to HIV/AIDS knowledge. A total of 43.2% expressed willingness to treat patients with HIV/AIDS, which was higher in Xinjiang than in the Beijing-Tianjin-Hebei region (48.5% vs. 36.1%). Moreover, 32.6% had prior experience treating patients with HIV/AIDS, which was also the higher proportion in Xinjiang (44.9%) compared with the Beijing-Tianjin-Hebei region (16.1%) (P<0.05). Dentists with previous treatment experience were more likely to provide treatments again than those without such experience (OR=3.517, 95% CI: 1.810-6.832, P=0.001). Conclusions: Dentists in Xinjiang showed higher willingness to treat patients with HIV/AIDS than those in the Beijing-Tianjin-Hebei region, despite comparable levels of HIV/AIDS-related knowledge. These findings highlight the need for region-specific continuing education strategies that strengthen clinical exposure to improve equitable oral care for patients with HIV/AIDS in China.

Diagnosis and Treatments: The patient visited the Ophthalmology Department due to ‘congestion in both eyes and blurred vision’. He was advised to consult the Department of Oral Mucosa to rule out mucous membrane pemphigoid. A review of the medical history revealed that the patient developed gingival hyperemia two years ago, which did not receive treatment. The diagnosis of MMP was confirmed based on clinical examination, histopathology, and direct immunofluorescence. Treatment involved a stepped regimen of systemic glucocorticoids combined with immunosuppressants, underpinned by multidisciplinary management involving departments of oral medicine, ophthalmology, and endocrinology. Results: After 13 months of treatment, the oral lesions completely resolved, active ocular inflammation was effectively controlled, and symblepharon stabilized without progression. The systemic glucocorticoid dosage was successfully reduced to a maintenance dose of 6mg/d, creating conditions for subsequent ocular surgery. Conclusions: For high-risk MMP, early and accurate diagnosis is the prerequisite. An individualized, stepwise treatment strategy centered on systemic immunosuppression, with participation from multiple disciplines, is crucial for disease control, prevention of scar formation, and improvement of patient prognosis.
