Objective To analyze the relationships of the gene polymorphism of tumor necrosis factor -α( TNF-α) with the susceptibility to sepsis and its infections degrees .Methods We selected 80 patients with sepsis , including 32 pa-tients with severe sepsis ( group A) and 48 patients with systemic inflammatory response syndrome ( SIRS) ( group B) , and selected 50 healthy persons as the controls ( group C) .Polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) was used to investigate the genetypes on site 308 and 238 of TNF-α.Results In the group A, the frequen-cies of GG, GA and AA genetypes on 238 G/A site of TNF-αwere 78.13%, 18.75%and 3.13%;and the allele frequen-cies of G and A were 87.50%and 12.50%.In the group B, they were 85.44%, 14.58%, 0, 92.71%and 7.29%;and 88.00%, 12.00%, 0, 94.00%and 6.00%in the group C.In the group A , the frequencies of GG , GA and AA gene-types on 308 G/A site of TNF-αwere 75.00%, 18.75%and 6.25%;and the allele frequencies of G and A were 84.38%and 15.62%.In group B, they were 83.22%, 14.58%, 2.08%, 90.63% and 9.37%; and 86.00%, 14.00%, 0, 93.00%and 7.00%in the group C.There were no statistically significant differences in the genetypes and allelic gene distribution among these three groups (all P>0.05).Conclusions The gene polymorphisms of TNF-α-238 and TNF-α-308 were not significantly related with the susceptibility and infectious degrees of sepsis .
