ABSTRACT
Parkinson's disease (PD) is one of the hotspots in the research field of neurodegenerative diseases, and its pathogenesis is still controversial. Trace metal elements play an important role in normal growth and development of the human body. Metal ions can cross the blood-brain barrier and enter the brain, leading to α-synapnuclein aggregation, mitochondrial dysfunction, and degeneration of dopaminergic neurons, and then inducing the occurrence of PD. This article mainly reviewed the potential mechanisms of metal elements in PD, discussed the role of metabolic imbalance of common trace metals (copper, iron, manganese, and zinc) in PD, and put forward new insights into the treatment of PD.
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.
