Abstract

The invention provides application of a myristic acid-glycerol composition in evaluating the curative effect of a TKI (Tyrosine Kinase Inhibitor) on chronic myelocytic leukemia (CML), and belongs to the technical fields of metabonomics and clinical examination. In the experiment, a GC-MS (Gas Chromatography-Mass Spectrometer) combined technique is used for researching the plasma small molecular metabolite of CML patients. a newly diagnosed CML group of 26 cases of samples, a TKI treatment success group of 26 cases of samples, a TKI treatment failure group of 26 cases of samples and a health control group of 26 cases of samples are randomly selected to be taken as substance discovery models; verification of 194 cases of samples is performed according to substances screened from small samples. The myristic acid-glycerol combination level of the plasma of the CML patients can be taken as a potential marker for predicting the curative effect of the TKI through sample collection, pretreatment, sample separation and detection, and data processing, and a novel plasma metabolic marker is provided for clinical judgment on the curative effect of the TKI.

Description

technical field [0001] The invention belongs to the technical field of metabolomics and clinical testing, and specifically relates to the use of gas chromatography-mass spectrometry (GC-MS) metabolomics technology to screen the combined levels of myristic acid and glycerol in the plasma of CML patients, which can be used as a predictor of TKI curative effect. potential markers. Background technique [0002] Chronic myelogenous leukemia (CML) is a group of malignant clonal proliferative diseases of the blood system, and its molecular genetics is characterized by the translocation of the long arms of chromosomes 9 and 22, resulting in the BCR-ABL fusion gene, BCR-ABL The expression of fusion gene is mainly through changing the protein tyrosine phosphorylation level of malignant tumor cells, thereby destroying a series of normal signal transduction pathways, and finally leading to the inhibition of cell apoptosis. Tyrosine kinase inhibitor (TKI) is a targeted anti-tumor drug d...
