摘要
目的通过对云南非铀矿山矿工血清IL-2、IL-6和TNF-α浓度及基因多态性位点的检测,对氡致非铀矿山矿工机体生物效应进行初步探讨。方法血清中IL-2、IL-6和TNF-α的浓度测定采用双抗夹心ABC—ELISA法。TNF-α(-308,G→A)检测基因型采用基因体外扩增限制性片段长度多态性分析方法,IL-2(-330,T→G)基因型检测采用PCR体外扩增后测序的方法。结果矿工组与对照组比较,年龄(F=1.07,P〉0.05),工龄(F=0.40,P〉0.05),血清IL-2浓度(F=0.71,P〉0.05),血清IL-6浓度(F=1.09,P〉0.05),血清TNF-α浓度(F=0.95,P〉0.05),IL-2基因型频度(χ^2=0.02,P〉0.05)和TNF-α基因型频度(χ^2=2.21,P〉0.05),差异均无统计学意义。结论云南东川非铀矿山矿工血清IL-2、IL-6和TNF-α平均浓度有下降的趋势,TNF-α(-308,A/A)基因型频度有增高的趋势。
Objective To study biologic effect of high radon exposure in non-uranium miners by measurements of serum levels of IL-2, IL-6 and TNF-α and study on their gene polymorphism. Methods Serum levels of IL-2, IL-6 and TNF-α in the miners selected from a Yunnan-based copper mine were measured by ABC- ELISA. TNF-α ( -308, G→A) genotypes were identified by RFLP-PCR, IL-2 ( -330, T→G) genotypes by sequence analysis. Results Compared the miners with its control group, there were no statistical significance of the concentrations of serum IL-2 ( F = 0.71, P 〉 0.05), IL-6 ( F = 1.09, P 〉 0.05) and TNF-α ( F = 0.95, P 〉 0.05). Frequencies of IL-2 ( - 330, T→G) genotypes ( χ^2 = 0.02, P 〉 0.05) and TNF-α ( - 308, G→A) genotype (χ^2 = 2.21, P 〉 0.05) were shown no statistical significance too. Conclusions Compared with the control group, concentrations of serum IL-2, IL-6 and TNF-α in miners working in the copper mine was lower, frequencies of genotypes of TNF-α ( -308, A/A) was higher in the miners. But all the differences were not statistical significant.
