Abstract
We performed a metabolomics study using liquid chromatography-mass spectrometry (LC-MS) combined with multivariate data analysis (MVDA) to discriminate global urine profiles in urine samples from esophageal squamous cell carcinoma (ESCC) patients and healthy controls (NC). Our work evaluated the feasibility of employing urine metabolomics for the diagnosis and staging of ESCC. The satisfactory classification between the healthy controls and ESCC patients was obtained using the MVDA model, and obvious classification of early-stage and advanced-stage patients was also observed. The results suggest that the combination of LC-MS analysis and MVDA may have potential applications for ESCC diagnosis and staging. We then conducted LC-MS/MS experiments to identify the potential biomarkers with large contributions to the discrimination. A total of 83 potential diagnostic biomarkers for ESCC were screened out, and 19 potential biomarkers were identified; the variations between the differences in staging using these potential biomarkers were further analyzed. These biomarkers may not be unique to ESCCs, but instead result from any malignant disease. To further elucidate the pathophysiology of ESCC, we studied related metabolic pathways and found that ESCC is associated with perturbations of fatty acid β-oxidation and the metabolism of amino acids, purines, and pyrimidines.

Abstract
Procedures are described for the isolation and identification of adenosylmethionine from human urine. Previously described preliminary separative procedures using anion and cation exchange columns and an XAD-4 resin column have been extended to permit the separation of adenosylmethionine. The adenosylmethionine has been identified by conversion to methylthioadenosine followed by rechromatography of the latter compound with three different types of columns and elution systems. Mean adenosylmethionine values for urine were as follows: adults, 0.26; children, 0.36 nmole/mumole creatinine. Recovery of adenosylmethionine added to urine and determined by this separative procedure was 52%.
