ABSTRACT: Objective To analyze the influence of tumor necrosis factor-alpha(TNF-α)-308 genomic polymorphism on pneumoconiosis and its severity. Methods Eight documents which involve 2388 cases about the influence of TNF-α-308 genomic polymorphism on pneumoconiosis and its severity during the 31 years in China were analyzed by meta-analysis Results There were 1005 patients and 1383 controls for TNF-α-308 genotype in 8 researches.-308 A gene frequency of patients was obviously higher than controls. The odds ratio(OR) value was 1.71.The 95% Confidence interval (95%CI) was1,21~2.43,(P0.01).While -308 A gene frequency of patients at stage Ⅲ was obviously higher than stage Ⅰ.The OR value was 2.39.95%CI=1.13~5.04,(P0.05).
