Background: Glycyrrhiza is one of the most widely used traditional Chinese medicines in China. Its main bioactive ingredient glycyrrhizic acid (GA) has the potential to be used as a treatment for atopic dermatitis (AD) because it has similar actions to steroids, but with relatively few side effects.
Aims: The objective of this study was to explore the potential mechanisms of GA on AD mice model.
Methods: Calcipotriol, a vitamin D3 analogue (MC903) was applied topically to establish AD mouse model. Mice were intraperitoneally administrated with 2 mg/kg dexamethasone (DEX), 25 or 50 mg/kg GA for 15 days. After mice were executed, skin tissues were collected and detected the expression levels of IL-4, IFN-γ, TNF-α and thymic stromal lymphopoietin (TSLP). The percentages of Th1, Th2, Th17, langerhans cells (LCs) in draining lymph nodes (dLNs) were measured by flow cytometry.
Results: Our data demonstrated that GA improved the symptoms of AD by exerting anti-inflammatory and anti-allergic functions in vivo. We found that GA treatment decreased the level of total IgE in serum, suppressed ear swelling, reduced the infiltration of mast cells in skin lesions and decreased expressions of IL-4, IFN-γ, TNF-α and TSLP in skin lesions. Furthermore, our experimental results demonstrated that GA suppressed the Th1/Th2/Th17-immune responses in the dLNs, inhibited the migration of LCs in dLNs.
Conclusions: In conclusion, our findings suggested potential therapeutic effects of GA against MC903-induced AD-like skin lesions in mice.

Background: Previous studies have proven that 308-nm light-emitting diode(308-nm LED)and 308-nm excimer lamp(308-nm MEL) are effective in treating vitiligo, but there is a lack of comparison of their efficacy for facial lesions.
Objective: To evaluate and contrast the treatment success rates of 308-nm LED versus 308-nm excimer lamp in managing facial lesions among patients suffering from stable non-segmental vitiligo.
Methods: The enrolled 119 patients with 145 lesions were randomly assigned to receive 308-nm LED or 308-nm MEL for two months.

Our study aimed to investigate the correlation between skin cancer and anti-interleukin (IL) therapy in patients with moderate-to-severe psoriasis. This was an observational monocentric study in which we enrolled a total of 235 patients in which 127 patients were affected by moderate-to-severe psoriasis and treated with anti-IL monoclonal antibodies (mAbs) for at least 6 months, whereas 108 patients affected by mild psoriasis were treated with topical therapies. Afterward, we performed a dermatologic visit to all the subjects, collecting anamnestic information including risk factors for skin cancer.
