中文摘要:

目的探讨甘露糖结合蛋白(MBP)基因多态性与中国人肺结核发病的关系。方法采用病例对照研究，收集肺结核病例125例和健康对照198名的环境因素暴露情况及静脉血，MBP基因多态性分析采用特异引物PCR方法，用SPSS 11.5软件进行危险因素的单因素分析和多因素非条件logistic回归分析。结果病例组和对照组MBP-52、54、57位点的等位基因突变频率分别为8.0％、7.2％、0.4％和5.3％、4.3％、0.5％，按性别分层的Mantel-Haensezl X2分析两组间差异无统计学意义。单因素分析表明体重指数、婚姻状况、卡介苗接种史、卡痕、结核病接触史及家族史、体力劳动、文化程度与肺结核的发生有关。在多因素分析中调整上述危险因素后，总MBP(OR=2.182，95％CI:1.058-4.499)和MBP-52突变型等位基因型(OR=2.574，95％CI:1.028-6.446)与肺结核发病有统计学意义。结论总MBP和MBP-52突变型等位基因可能与肺结核发病有关。

英文摘要:

Objective To explore the association between the genetic polymorphisms of mannosebinding protein(MBP) alleles and susceptibility to pulmonary tuberculosis.Methods 125 pulmonary tuberculosis cases and 198 healthy controls were collected.A case-control study was conducted.Threestructural gene mutations in exon 1 of MBP gene(codon 52, codon 54 and codon 57)were studied.Polymerise chain reaction with sequence-specific primers (PCR-SSP) was carried out in the polymorphism in MBP alleles.Information on related risk factors of tuberculosis was collected, using a pre-tested questionnaire.Univariate and multivariate logistic analyses were conducted with SPSS software package. Results The frequencies of mutant heterozygote or homozygote of MBP-52, 54, 57 were 8.0%, 7.2% and 0.4% for cases and 5.3%, 4.3%, 0.5% for controls, respectively.The distribution of mutant genotypes of MBP did not show significant difference between tuberculosis patients and control by Mantel-Haertszel x² on sex.The univariate analysis demonstrated that body mass index, marital status, vaccinal vestige, bacillus of Calmette-Guerin vaccine immunization, contacted with pulmonary tuberculosis patients, familial traits were the risk factors of pulmonary tuberculosis.After adjusting those related environmental factors in the multivariate logistic analyses, the total MBP(MBP-52, MBP-54 and MBP-57) and MBP-52 heterozygote genotypes were significantly overrepresented in cases, with adjusted OR(95% CI)being 2.182(1.058-4.499) and 2.574(1.028-6.446).Conclusion Total MBP and MBP-52 mutant genotypes might be associated with the susceptibility to pulmonary tuberculosis.
