摘要
目的探讨甘露糖结合凝集素(MBL)基因多态性与中国汉族人群肺结核发病间的关联。方法采用以医院为基础的病例对照研究设计,对结核病相关危险因素进行问卷调查。联合应用引物序列特异性PCR(PCR-SSP)和序列特异性寡核苷酸探针杂交(PCR-SSOP)等方法对MBL基因H/L、X/Y、P/Q和A/B四个多态性位点进行基因型分析及单倍体型分析。将各位点的基因型或单倍体型在病例组和对照组的分布进行比较,并将有显著作用的环境危险因素纳入进行多因素非条件logistic回归分析。结果 133名肺结核病例和177名对照纳入本研究,多因素分析调整结核病暴露史和疫苗接种史两个因素后,MBL基因的HL和LL基因型与疾病的保护作用显著相关,调整OR值(95%CI)分别为0.54(0.30-0.95)和0.50(0.26-0.96)。MBL基因XB组单倍体型与中国汉族人群肺结核发生的易感性显著相关,调整OR值(95%CI)为1.60(1.07-2.41)。而其余多态性位点,包括X/Y、P/Q和A/B位点与肺结核的发生均无显著性关联。结论中国汉族人群MBL基因多态性可能与汉族人群肺结核发生的易感性显著相关。
