ABSTRACT
Objective:
Explore the hydrogen-nuclear magnetic resonance ( 1H-NMR) application potential of metabolomics in early screening of vitamin A deficiency(VAD).Methods:
From January to June 2019, 40 cases of left-behind children with confirmed VAD <1 year old were enrolled in Zunyi area as VAD group, and 40 healthy children were selected as healthy control group.Urine from the 2 groups of children was collected and 1H-NMR spectrum was measured.By combining metabonomics technology and multivariate statistical analysis, the 2 groups of metabolites were compared, and the differential metabolites of children with VAD were screened out.Results:
Compared with VAD group [(0.56±0.10)μmol/L], the difference in the serum retinol concentration of healthy control group [(1.35±0.18)μmol/L] was statistically significant ( t=23.93, P<0.001). Compared with healthy group, VAD group showed higher level of methylmalonate, 2-ketoisovalerat, N-acetyl glycoprotein signal, dimethylglycine and betaine, with statistically significant differences (| r|>0.602, all P<0.05). The level of Isovalerylglycine, 2-hydroxyisobutyrate, creatine, phosphate choline/glycerophosphocholine, 4-PY and Hippurate were significantly decreased, with statistically significant differences (| r|>0.602, all P<0.05).Conclusions:
Compared with healthy children, children with VAD have differences in urine Metabolites.Differential metabolites are closely correlated with intestinal microecological ba-lance, digestive system diseases, respiratory system diseases, immune-related diseases, energy metabolism, growth and development.Urine 1H-NMR metabolomics analysis has potential application value in the early screening of VAD.
