About this trial

The incidence of autism spectrum disorders is increasing, about 1 / 36. Neural cadherin (NCAD) is closely related to synaptic structure and function. The cdh2 gene encoding NCAD has been shown to be associated with a variety of neurodevelopmental diseases and is one of the six risk genes for ASD. Functional near-infrared spectroscopy (fNIRS) is a neuroimaging technology that uses the principle of near-infrared spectroscopy to detect the functional activation of human cortex. The application of fNIRS to explore the neural mechanism of children with ASD has developed rapidly. It has the advantages of non-invasive, portable, relatively low cost and unlimited physical activity. And for ASD children, their command compliance and self-control are relatively low, so fNIRS is more widely used in ASD children. According to dsm-5 standard, we recruited ASD children and TD children, collected their peripheral blood, and detected the plasma n-cad concentration. At the same time, the resting state of fNIRS of the two groups of children was collected, and the ultra scan monitoring was carried out simultaneously during Gesell assessment. The purpose of this study was to explore the difference of peripheral blood NCAD concentration between preschool ASD children and TD children and the difference of brain function in resting state and social interaction state. And the relationship between the characteristics of brain function and the level of cognitive development in children with ASD.

Trial outcomes

Primary outcomes

N-CAD

NCAD concentration in peripheral blood: N-cadherin (NCAD) in peripheral blood is a calcium dependent cell adhesion molecule, which is mainly involved in cell-cell recognition and adhesion, and is commonly found in nerve tissue, muscle and vascular endothelium. In peripheral blood, the content is very low under normal conditions, but if N-cadherin is detected to be increased, it may be related to tumor metastasis (such as breast cancer, prostate cancer and other epithelial mesenchymal transition), vascular endothelial injury or some neurological diseases. It can be used as a potential biological marker of tumor invasion or vascular abnormalities, but its detection needs to be combined with other indicators to improve the accuracy.

fNIRS

FNIRS (resting state + superscan): functional near infrared spectroscopy (fNIRS) is a noninvasive brain imaging method that detects hemodynamic changes in the cerebral cortex (such as oxygenated hemoglobin and deoxyhemoglobin concentrations) through near-infrared light, thereby indirectly reflecting neural activity. Resting state fNIRS is used to study the spontaneous activity of the brain in the task-free state, and is often used to explore brain functional networks, disease markers (such as mental disorders or neurodegenerative diseases) and individual differences. While fNIRS hyperscanning synchronously records the brain activity of multiple subjects (such as two people interacting), which is used to study the inter brain synchronization in social cognition, cooperation or competition, and reveal the interpersonal neural mechanism. The combination of the two can expand the understanding of brain resting function and social interaction, and is suitable for psychology, neuroscience a
