Analysis on the metabolite composition of serum samples from patients with papillary thyroid carcinoma using nuclear...

Analysis of the metabolic differences among the papillary thyroid carcinoma (group T) patients, benign thyroid tumor patients (group B) and healthy controls (group H) by nuclear magnetic resonance hydrogen spectrum.

collect twenty serum specimens each from group T, group B and group H. Collect image archive. Use Topspin software, AMIX software and SIMCA-P+ software to calibrate, integrate with PCA and PLS-DA, research the three groups' serum for endogenous metabolic differences.

The data of group T and group H established a discrimination model, and the model is correct (P<0.05). The content of metabolites in the serum of team T increased including valine, leucine, isoleucine, lactic acid, alanine, glutamic acid, lysine, glycine, while the lipids, choline, tyrosine decreased. The data of group B and group H established a discrimination model and the model is correct (P<0.05). The content of metabolites in the serum of team B increased including Trimethyl glycine, tyrosine, phenylalanine, valine, leucine, isoleucine, lactic acid, alanine, glutamic acid, while the Lipids and lysine reduced.

Compared with team H, there is an obvious metabolic difference in team T and team B. It not only involves glucose metabolism but also the metabolism of lipids, amino acids and nucleic acid.
