Objective To explore the association of Toll-like receptor 4 TLR4 and lipopolysaccharide receptor CD14 gene polymorphisms with Kawasaki disease (KD) susceptibility.Methods Three-color fluorescent staining flow-cytometry was used to detect the expression of TLR4 in peripheral blood white blood cell of 76 KD children and 118 healthy control group.The gene of TLR4 (-896A/G), (-1196C/T) and CD14 (-260C/T) polymorphisms was identified by polymerase chain reaction-restriction fragment length polymorphisms; and the relationship between genotype and KD was analyzed.Results 1.The values of mean fluorescence intensity (MFI) of TLR4 in peripheral blood white blood cell of the KD groups and the healthy control groups were 2.87?0.96, 10.55?4.87, 23.36?8.28 and 3.26?0.65, 7.55?1.21, 25.41?6.97, respectively; There was a gradual increase of these values on lymphocyte, neutrophilic leukocyte and mononuclear cell in both groups.2.(-896A/G), (-1196C/T) polymorphisms of TLR4 gene were not found in both groups.3.The frequency of each genotype of CD14 gene (-260C/T) was 35.5%CC, 30.3%CT, 34.2%TT in KD group and 38.1%CC, 47.5%CT, 14.4%TT in healthy control group.The frequency of each genotype was significantly different in 2 groups(?2=11.62 P
