尿Ｎ－乙酰－β－Ｄ氨基葡萄糖苷酶（ＮＡＧ）和尿β２－微球蛋白（β２－ｍ），近年来在检测肾小管功能方面日益受到重视。我们检测了５６例经肾穿刺活检病理确认为轻度肾小管病变的肾病患者尿ＮＡＧ，尿β２－ｍ含量，旨在探讨在形态上同是轻度肾小管病变的肾病患者，由于尿 Urinary N-acetyl-β-D-glucosaminidase (NAG) and urinary β2-microglobulin (β2-m) have attracted increasing attention in recent years in detecting renal tubular function. We examined urinary NAG and urinary β2-m levels in 56 patients with nephrotic lesions confirmed by renal biopsy pathology. We aimed to investigate nephropathy in patients with morphologically mild tubular disease,
