Abstract:
OBJECTIVETo explore the relationship between interleukin-6 (IL-6) (-634C/G) genetic polymorphisms and the pneumoconiosis.
METHODSA total of 104 male stage I pneumoconiosis patients diagnosed by the Pneumoconiosis Diagnosis Expert Panel according to the Chinese National Diagnosis Criteria of Pneumoconiosis (GBZ 70 - 2002) were selected. The pneumoconiosis comprised 66 silicosis and 38 coal worker' pneumoconiosis (CWP). A total of 122 workers exposed to same dusts as the patients but without pneumoconiosis including 77 exposed to silica dusts and 45 to coal dusts were selected. The patients and the controls had the same dust exposure history. The peripheral venous blood was drawn from each subject. The IL-6 (-634C/G) genetic polymorphisms were detected by polymerase chain reaction restriction fragment length polymorphisms (PCR-RFLP) techniques.
RESULTSThe frequencies of IL-6 (-634C/G) (CC, CG and GG) genotypes were 66.7%, 19.7% and 13.6% in silicosis group, 42.9%, 42.9% and 14.2% in silica dust exposure group, 73.7%, 18.4% and 7.9% in CWP group, 51.1%, 35.6% and 13.3% in coal dust exposure group respectively. The statistical analysis indicated that there was significant difference in the frequencies of IL-6 (-634C/G) (CC, CG and GG) genotypes between silicosis patients and workers exposed to silica dusts (P < 0.05).
CONCLUSIONIL-6 (-634 C/G) genetic polymorphisms might play a role in the occurrence of silicosis.
