Objective:To study the changes of HSPs family expression in psoriasis lesions and their correlation with inflammatory response before and after narrow-band ultraviolet B (NB-UVB) treatment.Methods: Patients who were newly diagnosed with psoriasis vulgaris and treated in Dermatology Department of our hospital between March 2015 and May 2017 were selected and randomly divided into the NB-UVB group who received NB-UVB combined with conventional treatment and the control group who received conventional treatment. Before treatment and 20 d after treatment, proper amount of psoriasis lesion was collected to determine the expression of HSPs family molecules and lymphocyte transcription factors as well as the levels of inflammatory cytokines.Results: Compared with those before treatment, HSP27, HSP60, HSP90 , HSP90β, T-bet and Foxp3 mRNA expression as well as MCP-1, IFN-γ and IL-17 levels in psoriasis lesion of both groups significantly decreased whereas GATA-3 and RORγt mRNA expression as well as IL-10 and TGF-β1 levels significantly increased after treatment, and HSP27, HSP60, HSP90 , HSP90β, T-bet and Foxp3 mRNA expression as well as MCP-1, IFN-γ and IL-17 levels in psoriasis lesion of NB-UVB group were significantly lower than those of control group whereas GATA-3 and RORγt mRNA expression as well as IL-10 and TGF-β1 levels were significantly higher than those of control group;HSP27, HSP60, HSP90 and HSP90β mRNA expression in psoriasis lesion of NB-UVB group after treatment were positively correlated with MCP-1, IFN-γ and IL-17 levels as well as T-bet and Foxp3 mRNA expression, and negatively correlated with IL-10 and TGF-β1 levels as well as GATA-3 and RORγt mRNA expression.Conclusion: NB-UVB treatment of psoriasis can reduce the expression of HSPs family members and inhibit the inflammatory response mediated by HSPs.
