Abstract:
Objective To explore the relationship between interleukin(IL)-13 RS20541 gene polymorphism and susceptibility of enterovirus 71 (EV71) infection in children's hand-foot-mouth disease.Methods Blood samples were collected from 123 children with EV71 infection from the Central Hospital of Xiangtan (experimental group),and they were divided into mild EV71 infection group (n =62) and severe EV71 infection group (n =61) according to their severity.And 52 healthy children without EV71 infection were selected as the controls,with age and sex matched.Two mL blood samples stored in the-80 ℃ freezer,were collected from all subjects,and DNA was extracted by Beijing ubiolab genetic technology company limited.The SNaPshot was used to determine genotype for G/A polymorphism at RS20541 position of IL-13 gene.SPSS 18.0 software was used to analyze the data.Results IL-13 RS20541 loci had 3 genotypes:AA,GA,GG;the frequency of AA,GA,GG in the experimental group was 4.07%,44.71%,51.22%,which was significantly lower than that in the healthy control group (the frequency of AA,GA,GG were 11.54%,32.69%,55.77%),there was no statistically significant difference in genotypes (x2 =4.676,P > 0.05);there was no statistically significant difference in allele frequency (the frequency of A,G in experimental group was 26.42 %,73.58 %,and that of the healthy control group was 27.88 %,72.12 %;x2 =0.080,P > 0.05).EV71 infection caused by mild group,severe group and healthy controls genotype frequencies between the 3 groups [(AA + GA) were 53.22%,44.26%,44.23%;GG were 46.78%,55.74%,55.77%;x2 =1.294,P > 0.05] and allele frequency (A were 30.65%,22.13%,27.88%;G were 69.35%,77.87%,72.12%;x2 =2.349,P > 0.05) among the mild group,severe group and healthy control group had no statistical significance.Conclusion There is no correlation between the IL-13RS20541 gene polymorphism and EV 71 infection in children with the hand-foot-mouth disease.
