摘要:

目的 探讨新生儿脐血胸腺基质淋巴细胞生成素(TSLP)基因多态性与婴幼儿特应性皮炎(AD)的关系。方法 选取足月分娩孕妇393例,提取其脐血基因组DNA,采用聚合酶链反应(PCR)-高温连接酶反应(LDR)检测TSLP基因rs3806933、rs1545169、rs764917、 rs1837253、rs2289276和rs11466749位点的基因型。有285例新生儿在其2岁时通过电话回访明确其出生后有无医生确诊的AD(诊断AD 162例)。结果 新生儿脐血TSLP基因rs3806933、rs1545169、rs764917、 rs1837253和rs2289276位点基因型分布频率在无AD组和有AD组间无明显差异(P>0.05)。rs11466749位点基因型(AA/AG)分布频率在AD组与无AD组间有明显差异(AD组rs11466749位点AA型占60.0%,AG型占34.3%;无AD组rs11466749位点AA型占40.0%,AG型占65.7%。结论 新生儿脐血TSLP基因rs11466749基因多态性与其2岁内AD有一定相关性。

Abstract:

Objective To investigate the correlation between thymic stromal lymphopoietin (TSLP)gene polymorphism in cord blood and toddler atopic dermatitis (AD). Methods A total of 393 pregnant women in a prospective birth cohort were enrolled. Genomic DNA was extracted from cord blood samples,and polymerase chain reaction (PCR)- ligase detection reaction(LDR) was used to detect rs3806933,rs1545169,rs764917,rs1837253,rs2289276 and rs11466749 mutations in TSLP gene. Totally,285 toddlers received a phone call questionnaire at the age of 2 to determine whether they had AD or not,which was judged by pediatricians after birth, and 162 cases were diagnosed AD. Results There was no statistical significance in the genotype distribution frequencies of rs3806933,rs1545169,rs764917,rs1837253 and rs2289276 between AD group and non-AD group (P>0.05). There was statistical significance in the genotype distribution frequency of rs11466749 (AA/AG)(AD group:rs11466749 locus 60.0% AA and 34.3% AG;non-AD group:rs11466749 locus 40.0% AA and 65.7% AG. Conclusions The gene polymorphism of TSLP gene rs11466749 in cord blood is correlated with AD.
