Research on Urine Metabolomics of HIV/AIDS Patients with Spleen-lung Qi-deifciency Based on H-NMR Technique / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to explore the characteristics of urine metabolomics among HIV/AIDS patients with spleen-lung qi-deficiency. H-NMR technique was combined with principal component analysis and cluster analysis in the comparison of urine metabolic products among 24 HIV/AIDS cases with spleen-lung qi-deficiency and 20 healthy control cases. The results showed that urine metabolic products of HIV/AIDS patients with spleen-lung qi-deficiency and healthy people by H-NMR technique detection and PLS-DA analysis can classify the outline of urine metabolites. There were about 20 variables in the difference between two groups. The speculated substances contained glycyl-L-leucine, L-valine, α-aminobutyric acid, methyl succinic acid, glycine propionyl, and etc. It was concluded that H-NMR technique was able to classify the outline of urine metabolites between HIV/AIDS cases with spleen-lung qi-deficiency and healthy people. Part of the potential existed characteristic markers contributed to the clinical diagnosis of traditional Chinese medicine (TCM) syndrome differentiation of AIDS. It had certain effect in its quantitative analysis.
