Urinary protein profile of type 2 diabetic nephropathy and diagnostic decision tree / 中华内分泌代谢杂志

ABSTRACT

Urine samples from 72 patients with diabetic nephropathy (DN) were analyzed and compared to those from 33 diabetic patients without albuminuria and 29 normal controls,using SELDI-TOF-MS (surface enhanced laser desorptiort/ionization time-of-flight mass spectrometry) and Biomarker Patterns Software,to identify differences in protein profile,generate a tree analysis pattern and evaluate the validity of the decision tree.The intensities of 6 peaks detected appeared upregulated,while 11 peaks downregulated,in DN group as compared to nonDN groups more than 2 folds (P
