Application of urinary N-acetyl-β-D-glucosaminidase combined with serum retinol-binding protein in early detection of diabetic nephropathy.

Background: Diabetic nephropathy (DN) is a microangiopathy of type 2 diabetes mellitus (T2DM), which can damage the kidney through various ways and mechanisms due to the nature of the disease, involving the renal interstitium and glomeruli. However, in the early stage of the disease, patients only showed kidney volume increase and glomerular hyperthyroidism, and typical symptoms that are difficult to arouse individual attention were noticed.

Aim: To observe the expression of serum retinol-binding protein (RBP) and urinary N-acetyl-β-D-glucosaminidase (NAG) in patients with DN, and to analyze their value in disease prediction, so as to provide new targets for early diagnosis and treatment of DN.
