Problems solved by technology

[0007] However, there has been no report on the metabolomic characteristics of TS so far. Therefore, this study screened out the plasma differences between TS patients and healthy children based on non-targeted metabolomics, and further analyzed the differential compounds based on targeted metabolomics technology. For verification, the obtained differential metabolites are applied to the clinical diagnosis of TS, and the detection of plasma is non-invasive and non-invasive. Therefore, screening early diagnostic markers for TS in children from plasma can be accurately and conveniently used for clinical diagnosis. Provide evidence for doctors to formulate early diagnosis and intervention plans

Abstract

The invention discloses a blood plasma metabolic marker related to the diagnosis of Tourette syndrome (TS) in children and its application. The markers are L-arginine and D-pipericolic acid. The markers of the present invention can diagnose the risk of TS in children from the perspective of metabolites, and the results are accurate, objective and reliable, can well distinguish the TS group from the normal group, can accurately and sensitively evaluate the risk of TS, and only need to provide blood samples It can be carried out without other tissue samples, greatly improving the possibility and feasibility of clinical application, and providing guidance for clinicians to formulate early diagnosis and intervention plans.

Description

technical field [0001] The present invention relates to the field of metabolomics and medicine, in particular to a plasma metabolic marker related to the diagnosis of children's tic syndrome and its application. Background technique [0002] Tourette syndrome (Tourette syndrome, TS), also known as Tourette syndrome, is a chronic neuropsychiatric disorder with onset in childhood and can last until adolescence. It is characterized by motor tics and / or vocal tics in one or more parts of the body. Common motor tics can be manifested as eye blinking, eyebrow raising, grinning, shrugging, etc. Vocal tics such as throat humming, throat clearing, Screams, foul language, etc. In addition, children often have comorbidities such as attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), autism spectrum disorder (ASD), oppositional defiant disorder (ODD) and other disruptive behaviors. TS was once considered a rare disease, but the latest epidemiological ...
