Objective:To study the effects of suppressor of cytokine signaling 1 (SOCS1) and SOCS3 in peripheral blood on CD4+T cell differentiation in children with Henoch-Schonlein purpura. Methods: Children with Henoch-Schonlein purpura who were treated in Zigong Maternal and Child Health Hospital between June 2014 and February 2018 were selected as the HSP group of the study, and healthy children who received physical examination during the same period were selected as the control group of the study. Peripheral blood was collected to determine the expression of SOCS1 and SOCS3 as well as the contents of CD4+T cell subsets, and serum was collected to determine the contents of CD4+T cytokines.Results: SOCS1 and SOCS3 mRNA expression levels as well as SOCS3/SOCS1 ratio in peripheral blood of HSP group were significantly higher than those of control group;Th1 and Treg contents in peripheral blood as well as IFN-γ and TGF-β1 contents in serum of HSP group were lower than those of control group whereas Th2 and Th17 contents in peripheral blood as well as IL-4, IL-5 and IL-17 contents in serum were higher than those of control group, and Th1 and Treg contents in peripheral blood as well as IFN-γ and TGF-β1 contents in serum of HSP children with high SOCS3/SOCS1 ratio were lower than those of HSP children with low SOCS3/SOCS1 ratio whereas Th2 and Th17 contents in peripheral blood as well as IL-4, IL-5 and IL-17 contents in serum were higher than those of HSP children with low SOCS3/SOCS1 ratio.Conclusions: Changes in SOCS1 and SOCS3 expression in peripheral blood of children with Henoch-Schonlein purpura can affect the differentiation of CD4+T cells.
