Lead-Burdened Type 2 Diabetic Nephropathy
Conditions
Brief summary
Based on previous basic experiments revealing that patients with type 2 diabetic nephropathy exhibit higher blood lead levels than the general population, this study aims to systematically evaluate the impacts of short-term and long-term blood lead exposure on renal function progression in such patients, so as to provide novel epidemiological evidence for clinical intervention.
