Clinical Application of Urinary Transforming Growth Factor-Beta(TGF-β1)Measurement in Diagnosing Chronic Nephritis / 现代检验医学杂志

ABSTRACT

Objective To investigate the level of urinary TGF-β1 and evaluate its clinical significance in patients with chronic nephritis.Methods 22 healthy people and 40 patients with chronic nephritis were selected,the levels of urinary TGF-β1 were measured by RT-PCR and ELISA.Results Urinary TGF-β1 were significantly increased in Mesangial Proliferative Glomerulonephritis (76.44± 24.29 ng/mmol.Cr vs 31.53 ± 11.59 ng/mmol.Cr,P<0.01);Focal Glomerular Sclerosis (65.07±20.59 ng/mmol.Cr vs 31.53±11.59 ng/mmol.Cr,P<0.01)and IgA Nephritis (67.01±21.95 ng/mmol.Cr vs 31.53±11.59 ng/mmol.Cr,P<0.01),comparing with normal group.Conclusion The levels of urinary TGF-β1 could be a predictor in reflecting the sate of renal diease,estimating pathological type,diagnosing the renal diease and observing the therapeutic effects.
