Abstract:
Objective:To study the expression level of peripheral blood mircoRNA-155 and the variation characteristics of CD4+T cell percentage and to expound the clinical significance of mircoRNA-155 quantitative test and CD 4+T cell percentage cytological test.Methods:Fluorescent quantitative PCR had been used to detect the expression level of mircoRNA -155 in the peripheral blood.Flow cytometry had been used to detect the cell percentage of the peripheral blood T lymphocyte subset CD 3+T cell,CD4+T cell and CD8+T cell.The mircoRNA-155 expression levels and the cell percentages of CD 4+T were tested respectively in the selected 40 patients with atopic dermatitis ,30 patients with skin eczema and 30 healthy controls.Finally,the differences of the above groups were counted and analyzed .Results:The relative expression levels of mircoRNA-155 of the atopic dermatitis group were higher than those of the eczema group and the normal control group ( P<0.05 ).The CD4+T cell percentage of the atopic dermatitis group was higher than those of the eczema group and the normal control group ( P<0.05 ) .Conclusion: The expression level of the peripheral blood mircoRNA-155 in the patients with atopic dermatitis is increased significantly and CD 4+T cell percentage in the patients is raised as well.Consequently ,the clinical detection of miRNA-155 and CD4+T cell shall be of great significance .
