Abstract:
Objective To study whether L-cysteine and lysolecithin (16:0) could be as a serum markers in the detection of OVC for overcoming the OVC defects of early detection .Methods Totally 142 cases of healthy check -up patients ( control group ) 100 cases from First Affiliated Hospital of Wenzhou Medical University in January 2012 to January 2014 were extracted patient specimens .These pa-tient specimens were used to detect by MALDI -TOF-MS mass spectrometer and obtain the peak m/z by the method of principal compo-nent analysis for screening expression difference between the two groups in the metabolites and the correlation between metabolites and pathological grade.Results The most difference substance between two groups were 184.05 and 496.30m/z which identified as LPC (16:0) and HCA;On HCA average level and detection rate , OVC group was significantly higher than control (P<0.01); On 184.05 and 496.30m/z peak area, control group was significantly higher than OVC group (P<0.01);HCA positively was correlated with patho-logic grade (P<0.05);184.05 and 496.30 m/z peak area were negative correlation with pathologic grade (P<0.05).Conclusion L-cysteine and lysolecithin (16:0) mechanism in the pathogenesis of OVC is unclear , but it can be used for the detection of serum OVC markers.
