ABSTRACT

Objective To investigate the expression and significance of Toll-like receptors-4 in peripheral blood and placental tissue in gestational diabetes mellitus (GDM) patients.Methods From February 2013 to February 2015.a total of 30 cases of gestational diabetes mellitus patients(GDM group) and 30 cases of normal pregnant people(health group)were selected as research objects.Peripheral blood and placental tissue of two groups were collected.The expression of TLR4 mRNA in peripheral blood mononuclear cells was detected by RT-PCR,the expression of TLR4 protein in placenta tissue was detected by immunohistochemistry.Results The expression of TLR4 mRNA in peripheral blood mononuclear cells of the observation group was significantly higher than that of the health group[(0.63±0.12) vs.(0.32±0.07)],the difference was statistically significant(t=12.223,P<0.05).The expression of TLR4 in villous trophoblast cells,decidual cells and amniotic epithelial cells in GDM group was significantly higher than that in the health group(Z=2.325,2.374,2.162,P<0.05).Conclusion The expression of TLR4 in peripheral blood mononuclear cells,villous trophoblast cells and decidual cells in gestational diabetes mellitus patients significantly enhanced,suggesting that TLR4 might be related to the e gestational diabetes mellitus.
