Abstract:
Objective Analysis of 22 kinds of organic acid metabolites in urine samples of patients with myasthenia gravis, mitochondrial myopathy and of healthy controls was performed so to provide data and basis for clinical screening .Methods The principal component and the corresponding principal component equation were obtained , the physical and chemical significance of the principal component was explained .Results The cumulative contri-bution rate of the first five principal components reached 86.89%, was identified as the main component , then es-tablished the principal component function expression , and analyzed the relationship between the principal compo-nent and the original variable .It was found that the phenyl saturated acid might be a potential biomarker of the two diseases , and the hippuric acid was an early warning bio-marker of the two diseases .Conclusions Urine organic acid metabolic profile principal component analysis is helpful to find biomarker of disease and may support clinical diagnosis basis .
