Objective: Based on magnetic beads based weak cation exchange chromatography (MB-WCX), matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) and ClinProTools software, the polypeptides of serum about occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) patients were studied, and a diagnostic model of OMLDT was built.
Methods: According to diagnostic criteria of OMLDT, serum of 28 OMLDT patients and 28 controls which were diagnosed by Shenzhen prevention and treatment center for occupational disease were collected. With the combination of MB-WCX and MALDI-TOF-MS, the polypeptides fingerprint of serum of 14 OMLDT patients and 14 controls were detected, what's more, the ClinProTools software and SNN algorithm was used for screening characteristic polypeptides and establishing diagnostic model of OMLDT.
