| Summary: | Objective: To study the correlation between urine albumin/creatinine ratio (ACR) in patients
with diabetic nephropathy and the content of serum oxidative stress and angiogenesis indexes
as well as peripheral blood T cells. Methods: Patients with type 2 diabetes were retrospectively
analyzed, and patients with ＜3 mg/mmol, 3-30 mg/mmol and ＞30 mg/mmol were screened
respectively as the DM1 group, DM2 group and DM3 group of the study; healthy volunteers
were selected as control group. Serum was collected to determine oxidative stress and
angiogenesis indexes, and peripheral blood was collected to determine the content of T cells.
Results: Serum SOD, GSH-Px and CAT content as well as peripheral blood Th2 and Treg
content of DM1 group, DM2 group and DM3 group were significantly lower than those of
control group and the higher the ACR, the lower the serum SOD, GSH-Px and CAT content as
well as peripheral blood Th2 and Treg content; serum MDA, 8-OHdG, VEGF, Ang1 and Ang2
content as well as peripheral blood Th1 and Th17 content were significantly higher than those
of control group and the higher the ACR, the higher the serum MDA, 8-OHdG, VEGF, Ang1
and Ang2 content as well as peripheral blood Th1 and Th17 content. Conclusion: Enhanced
oxidative stress, increased angiogenesis as well as T lymphocyte disorders are closely
associated with the progression of diabetic nephropathy.
