Among the tested compounds, 4, 5 and 13 exhibited potent antidepressant activities in the mice forced swimming test. Compounds 4 and 5 have potent antidepressant activities and are worth further development.

Objective To detect genetic causes of idiopathic mental retardation/developmental delay in 20 male patients with epilepsy and to analyze their clinical characteristics of positive mutation carriers.Methods The families,consisted of the patient and his parents were recruited.Genomic DNA was extracted from peripheral blood,and candidate gene mutation screening was carried out by next-generation sequencing technology.Mutations in positive gene were verified by polymerase chain reaction(PCR) and direct sequencing.Results Three missense mutations were identified among 3 patients out of 20 cases,with a detection rate of 15％.They were:OPHN1 gene c.1996 C ＞ G,RAB39B gene c.542 C ＞ T and AFF2 gene c.427 A ＞ T,none of which had been reported before.All of these mutations were likely to be pathogenic based on gene function,evolutionary conservation,variant frequency in normal population (NHLBI Exome Sequencing Project and 1 000 Genomes),bioinformatics prediction and inheritance patterns.In addition,all 3 genes disrupted were residing on the X chromosome previously demonstrated to be associated with X-linked mental retardation(XLMR),indicating that they were probably pathogenic or might serve as one of the risk factors.Conclusions Abnormal function of genes on the X chromosomal is one of the most impotent causes of XLMR.X chromosomal gene mutation screening would be recommended for male children suffering from idiopathic mental retardation with epilepsy.

Objective To investigate the clinical and MR features of fungal encephalopyosis and fungal granuloma.Methods The clinical and MR data of 10 cases with fungal encephalopyosis and fungal granuloma confirmed by surgical pathology or clinical serum were analyzed retrospectively.Then we analyzed the clinical conditions,MR signals,lesion enhancement,DWI and MRS performance characteristics of the 10 cases.Results Six cases were fungal encephalopyosis,among which 2 cases occurred in the sella turcica after surgery which located in and above the sella turcica.2 cases occurred in the frontal lobe after frontal surgery and 1 case of them was multiple encephalopyosis.2 cases of encephalopyosis without operation history were located in the left frontal lobe and right cerebellum respectively.The abscess walls of these cases were thin and showed high tension.Furthermore,it had annular significant signal enhancement and high signal in DWI scan.One case of huge fungal granuloma located in the frontal lobe and into the sinuses which showed uneven signal enhancement. The Cho level was significantly increased.Three cases of cryptococcal granuloma showed multiple lesions located in the bilateral basal ganglia region and 2 out of them accompanied with cephalomeningitis.Conclusion The MR performance of fungal encephalopyosis was quite similar with bacterial brain abscesses,which makes the differential diagnosis difficult.The brain fungal granuloma MRS may display a significant increase of Cho level which might be related with gliosis.It shows certain characteristics of brain MR performance of cryptococcal granuloma which are multiple lesions,preferential distribution of basal ganglia region and accompanying cephalomeningitis.

Objective:To report the clinical features of KCNQ2-associated epilepsy and the novel mutations and unreported clinical phenotype of KCNQ2 gene, so as to provide help for treatment selection and prognosis evaluation.Methods:Among 979 patients with epilepsy and developmental delay who were admitted to the Department of Neurology,Children′s Hospital Affiliated to Capital Institute of Pediatrics from July 2015 to October 2019, a total of 13 patients were selected from 12 families with KCNQ2 gene mutation by whole exome sequencing technology. Suspected mutations were verified by Sanger sequencing on the probands and their parents to identify the source. The clinical phenotype and genotype were analyzed according to these results.Results:Among the 13 patients with epilepsy, the onset age of four cases were older than six months [two cases in infancy (epilepsy encephalopathy), one case in early childhood (epilepsy encephalopathy) and one case in adolescence (benign epilepsy)]. Eight cases were treated with oxcarbazepine, of whom five cases were seizure free, and two cases showed partial response (>50%). Two cases treated with topiramate were seizure free. Five novel mutations were found in this research, including c.379T>G(p.Y127D), c.1A>C(initial codon mutation), c.708G>C(p.W236C), c.1027G>T(p.A343S) and c.1649T>G(p.V550G).Conclusions:Although it was rare in clinical work, the variation of KCNQ2 gene existed in patients with childhood-onset epilepsy and adolescent-onset epilepsy. Meanwhile, five novel mutations of KCNQ2 gene were reported, which further expanded its gene spectrum. This research supported that oxcarbazepine was the efficient medicine for the KCNQ2-associated epilepsy. Genetic testing showed great help to the treatment of epilepsy.
