摘要: Lung cancer is one of the most common and lethal cancers in world. In this study, a home-devised hydrophilic interaction chromatography/RPLC-MS (HILIC/RPLC-MS) system was developed to study urinary metabonomics lung patients. This combined orthogonal selectivity HILIC RPLC could chromatographically reveal more comprehensive information metabolites. Within total analysis time 50 min, we detected 577 polar metabolite ions on first column 261 apolar ones second column. addition, an signal correction partial least-squares discriminant model constructed characterize differences between health cases. Eleven potential biomarkers, ten from RP column, were identified all these biomarkers found upregulated Overall, results indicated that HILIC/RPLC-MS promising tool for metabonomic studies revealing highly complex samples.
