Résumé

Objective:The purpose of this study was to analyze the expression profile of miRNAs in children with autism spectrum disorders (ASD), and to discuss the clinical significance of differentially expressed miRNAs.Methods:MiRNA microarray was used to analyze the expression of miRNA in peripheral blood of 3 pairs of ASD patients-healthy controls; 17 pairs of ASD patients-healthy controls were used to verify the differentially expressed miRNA; Receiver operating characteristic (ROC) curve was used to analyze the differential expression the value of miRNA in the diagnosis of ASD.Results:A total of 32 differentially expressed genes were screened by 3 pairs of miRNA microarray including 12 up-regulated miRNAs and 20 down-regulated miRNAs. miRNA verification of 20 differentially expressed miRNAs showed miR-15a-5p, miR-27a-3p , miR-142-3p and miR-142-5p were significantly down-regulated in children with ASD, with statistically significant difference (all P<0.05). ROC curve analysis showed that the area under the curve (AUC) of the above four miRNAs diagnosing ASD were all greater than 0.70, with sensitivities 94.12%, 100%, 100%, and 82.35%, respectively. Conclusions:The expression of miR-142-3p, miR-27a-3p/miR-15a-5p, and miR-142-5p is down-regulated in the peripheral blood of ASD patients, and has the potential as biomarkers for early screening of ASD.

Résumé

Epilepsy is one of the common diseases of nervous system.Most children′s epilepsy can be controlled by drug treatment, but 20%—30% of children with epilepsy still have poor control effect after treatment, and eventually develop into intractable epilepsy, which seriously affects their healthy growth.In recent years, it has been found that the intestinal flora has two-way connection with the brain through the brain-intestine axis, including vagus nerve, neuroendocrine hypothalamic-pituitary-adrenal axis, intestinal immune system, neurotransmitters and neuroregulatory factors, which have a significant impact on the physiological, behavioral and cognitive functions of the brain, thus playing a role in the occurrence and development of epilepsy.Intestinal flora is closely related to epilepsy and may be a target for epilepsy treatment.Therefore, this review summarized the potential role of intestinal flora in epilepsy treatment.
