目的:研究盐亭县人群白细胞介素-23(IL-23)受体基因多态性与上尿路结石易感性的关联。方法:应用简单随机抽样法选取盐亭县人民医院2020年2月—2023年2月收治的上尿路结石患者104例作为结石组,另选取100例健康体检者为健康组。比较两组IL-23受体基因相关位点的多态性,分析IL-23受体基因多态性与上尿路结石易感性的关系。结果:结石组IL-23受体基因rs10889677位点AA基因型人数占比低于健康组,CC基因型人数占比高于健康组,差异有统计学意义(P<0.05)。结石组IL-23受体基因rs11465817位点AA基因型人数占比高于健康组,CC基因型人数占比低于健康组,差异有统计学意义(P<0.05)。IL-23受体基因rs10889677位点基因型为CC型、IL-23受体基因rs11465817位点基因型为AA型是盐亭县人群上尿路结石易感性的独立危险因素(P<0.001)。结论:IL-23受体基因rs10889677位点基因型为CC型、IL-23受体基因rs11465817位点基因型为AA型是盐亭县人群上尿路结石易感性的独立危险因素,提示IL-23受体基因多态性的检测可为早期识别上尿路结石易感人群及后续预防性干预措施的制定和实施提供参考。
