Objective To investigate the neuroimaging features of febrile infection-related epilepsy(FIRES).Methods The FIRES studies containing MRI imaging data were searched in PubMed,Ovid Medline,Scopus,Cochrane Library,Embase,Web of Science,CNKI,Wanfang database and VIP database.The search timeframe covered studies from 1998 to the present.Results A total of 28 studies involving 143 patients were included.In the acute phase,most FIRES patients had normal cranial MRI scans,though some may exhibit abnormal signals in areas such as the temporal lobe and basal ganglia.As the disease progresses,chronic phase MRIs often show generalized brain atrophy and medial temporal lobe sclerosis.Conclusion Although the imaging manifestations of FIRES lack specificity,it is of great significance for the diagnosis and differential diagnosis of the disease to be familiar with and understand the common manifestations of head MRI in different periods of FIRES.

Epilepsy is one of common diseases of nervous system,which is mainly manifested as repeat-ed abnormal neuronal discharges in the brain.If it cannot be effectively controlled,it can cause irreversible neuronal damage in the brain.Non-coding RNAs plays an important role in the development and progression process of epilepsy and are involved in regulating autophagy,apoptosis,neuroinflammation,synaptic remode-ling and other physiological and pathological processes,especially in the regulation of autophagy in epileptic neuronal cells.This article reviews the regulatory relationship between microRNA and long non-coding RNAs,circRNAs in non-coding RNAs with autophagy in the occurrence and development of epilepsy to pro-vide a direction for the precise treatment and prevention of epilepsy.

OBJECTIVE: To explore the clinical feature and genetic variant of a child with autosomal recessive Charlevoix-Saguenay type spastic ataxia (ARSACS). METHODS: Clinical data of a child who was admitted to the West China Second Hospital of Sichuan University on April 30, 2021 was collected. Whole exome sequencing (WES) was carried out for the child and his parents. Candidate variants were verified by Sanger sequencing and bioinformatic analysis based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). RESULTS: The child, a 3-year-and-3-month-old female, had a complain of "walking instability for over a year". Physical and laboratory examination revealed progressive and aggravated gait instability, increased muscle tone of the right limbs, peripheral neuropathy of the lower limbs, and thickening of retinal nerve fiber layer. The results of WES revealed that she has harbored a maternally derived heterozygous deletion of exons 1 to 10 of the SACS gene, in addition with a de novo heterozygous c.3328dupA variant in exon 10 of the SACS gene. Based on the ACMG guidelines, the exons 1-10 deletion was rated as likely pathogenic (PVS1+PM2_Supporting), and the c.3328dupA was rated as a pathogenic variant (PVS1_Strong+PS2+PM2_Supporting). Neither variant was recorded in the human population databases. CONCLUSION The c.3328dupA variant and the deletion of exons 1-10 of the SACS gene probably underlay the ARSACS in this patient.

The GATOR1 complex is located at the upstream of the mTOR signal pathway and can regulate the function of mTORC1. Genetic variants of the GATOR1 complex are closely associated with epilepsy, developmental delay, cerebral cortical malformation and tumor. This article has reviewed the research progress in diseases associated with genetic variants of the GATOR1 complex, with the aim to provide a reference for the diagnosis and treatment of such patients.
