The SOD-Mn gene rs4880 locus polymorphism and oxidative stress molecule expression in peripheral blood as well as the contents of renal function indexes and oxidative stress indexes in serum were determined.Results: The constituent ratio of SOD-Mn gene CC genotype in DN group was lower than that in control group whereas the constituent ratio of CT+TT genotype was higher than that in control group;serum T-AOC contents as well as peripheral blood Nrf2 and SIRT1 expression intensity of DN group of patients with CC genotype and CT+TT genotype were significantly lower than those of control group whereas serum Scr, BUN, CysC,β2-MG, MDA, AOPP, 8-OHdG and 8-Iso-PGF2α contents as well as peripheral blood NOX4, NOX5, p38MAPK and NF-κB expression intensity were significantly higher than those of control group, and serum T-AOC content as well as peripheral blood Nrf2 and SIRT1 expression intensity of patients with CT+TT genotype was significantly lower than those of patients with CC genotype whereas serum Scr, BUN, CysC,β2-MG, MDA, AOPP, 8-OHdG and 8-Iso-PGF2α contents as well as peripheral blood NOX4, NOX5, p38MAPK and NF-κB expression intensity were significantly higher than those of patients with CC genotype. Conclusion: The mutation from SOD-Mn gene rs4880 locus C to T can aggravate the renal function injury and oxidative stress response in patients with diabetic nephropathy.展开更多
