- 摘要:
- To explore the association between genetic polymorphisms of XRCC1, XPD, XRCC3 and CCND1 and latency of occupational chronic benzene poisoning.,80 patients diagnosed with occupational chronic benzene poisoning were investigated. PCR-RFLP was applied to detect the single nucleotide polymorphisms of C26304T, G27466A, G28152A, G36189A of XRCC1, C22541A, C23591T, A35931C of XPD, C18067T of XRCC3 and G870A of CCND1. Their relationship with the latency of chronic benzene poisoning was analyzed by Kaplan-Meier method.,The association of XRCC1 G27466A subgroup with the latency of chronic benzene poisoning was observed, as well as that of CCDN1G870A subgroup. The benzene-exposed workers with XRCC1 27466G/G homozygous wild genotype developed chronic benzene poisoning 6.9 years later than those had homozygous (27466A/A) or heterozygous (27466G/A) mutant alleles. On the other hand, the latency developing chronic benzene poisoning was longer in workers with homozygous (CCND1 870A/A) or heterozygous (CCND1 870G/A) mutant alleles than in those carrying 870G/G homozygous wild genotype (14.9 vs. 8.7 years).,The polymorphisms of XRCC1 and CCND1 potentially modify the latency of the chronic benzene poisoning among workers exposed to benzene.
