Objective:To summarize the genotype and clinical phenotype of children with WWOX gene related developmental and epileptic encephalopathy (DEE).Methods:Case series studies. The clinical data of 12 children with WWOX gene related DEE who were admitted to the Neurological Department of Children′s Medical Center, Peking University First Hospital from June 2019 to December 2023 were analyzed. The children′s characteristics of gene variation, clinical phenotype, auxiliary examination results, treatment and prognosis were analyzed.Results:Among 12 children with WWOX gene related DEE, there were 7 boys and 5 girls, the age of seizure onset ranged from 10 days to 6 months (median 1.8 months). Multiple seizure types were observed, including focal seizures in 10 cases, epileptic spasms in 9 cases, tonic seizures in 4 cases, myoclonic seizures in 1 case. Among 12 cases, 9 cases had multiple seizure types. All 12 cases showed microcephaly and global developmental delay. Video electroencephalography showed slowed background activity in 6 cases, hyperarrhythmia in 6 cases, multifocal discharges in 6 cases, and focal discharges in 1 case. Epileptic spasms were detected in 8 cases, tonic seizures in 4 cases and myoclonic seizures in 1 case. Brain magnetic resonance imaging showed bilateral frontotemporal subarachnoid space widening in 5 cases, deep sulci in 3 cases, bilateral ventricular enlargement in 2 cases, callosal hypoplasia in 5 cases, and delayed white matter myelination in 3 cases. The phenotypes of 12 cases were consistent with the diagnosis of DEE, and 8 of them were diagnosed with infantile epileptic spasm syndrome. All the WWOX gene variants in 12 cases were complex heterozygous variants, including 20 variants, 11 variants and 1 large intragenic WWOX gene deletion (p.Ala149Thr, p.Arg156Ser, p.R167Tfs*8, p.Leu186Val, c.605+5G>A, p.Trp218*, p.His263Arg, p.Leu275fs*19*1, p.N285Kfs*10, p.Ser304Tyr, p.Met326Arg, loss1 exon2-8) had not been reported previously. The age of last follow-up ranged from 11 months to 5 years and 3 months. During the follow-up, 1 case died at the age of 1 year and 10 months, 2 cases were seizure-free, and 9 cases still had seizures after multiple anti-seizure medications.Conclusions:The seizure onset age of children with WWOX gene related DEE is usually less than 6 months, and some of them in neonate. The common seizure types include focal seizures and epileptic spasms. Children usually have microcephaly and global developmental delay. WWOX gene related DEE usually has drug refractory epilepsy.

OBJECTIVES:
The prevalence of intrauterine adhesion (IUA) increased gradually, which seriously affected female reproductive health and fertility. This study aims to analyze the clinical features of pre-, intra-, and post hysteroscopic adhesiolysis (HA) and to identify the main risk factors for non-live birth and other factors affecting pregnancy outcome in patients with IUA.
METHODS:
A total of 486 IUA patients with reproductive needs, who underwent HA in the third Xiangya Hospital of Central South University from January 2017 to May 2018, were retrospectively included. The follow-up period was 2-3 years after operation. Univariate analysis and multivariate logistic regression analysis were used to explore the relationship between clinical features and live birth rate in patients with IUA. Pre-operative clinical indicators included age, gravidity, parity, abortion, IUA recurrence, menstrual patterns, and disease course. Intraoperative clinical features assessed in the last operation were uterine cavity length, IUA appearance, IUA area, number of visible uterine cornua, number of visible tubal ostia, and American Fertility Society (AFS) scores. The relationship between clinical indicators and postoperative live birth rate was investigated by univariate analysis and multivariate logistic regression analysis. Pregnancy pattern was the main variable.
RESULTS:
Among the 486 IUA patients included in this study, there were 256 (52.67%) live births and 230 (47.33%) non-live births. Univariate analysis and multivariate logistic regression showed that the live birth rate of in vitro fertilization and embryo transfer (IVF-ET) after HA was higher than that of spontaneous pregnancy (OR=0.557, 95% CI 0.361 to 0.861, P=0.008). When the bilaterally fallopian tube ostia were invisible in the last operation (OR=0.322, 95% CI 0.104 to 0.997, P=0.049), patients were more likely to have live birth. The older the patient was, the lower the live birth rate was (OR=1.081, 95% CI 1.034 to 1.131, P<0.001). The live birth rate would be low when the last AFS score was moderate (OR=2.973, 95% CI to 1.541 to 5.738, P<0.010).
CONCLUSIONS
Based on the outcome of the first pregnancy after HA, IUA patients' pregnancy patterns, age, number of visible tubal ostia, and AFS scores noted by a second-look hysteroscopy, are the factors influencing the prognosis for the live birth rate in IUA patients. IVF-ET may improve live birth rate for patients with IUA after HA.

Objective:To explore the molecular mechanism of pathological changes in osteoarthritis (OA) through applying bioinformatics to analyze the miRNA-mRNA regulatory network.Methods:MiRNA expression data from human serum samples were downloaded from the Gene Expression Omnibus database. Differentially-expressed miRNA was identified using the linear modelling package of the Bioconductor software suite. The target differentially-expressed mRNA was predicted using version 2.0 of the miRWalk database. Version 3.7.1 of the Cytoscape software was used to construct the miRNA-mRNA regulatory network for OA. The target genes were analyzed by using gene ontology and the Kyoto Encyclopedia of Genes and Genomes. The protein-protein interaction network was constructed and the core genes in osteoarthritis pathology were screened out.Results:A total of 7 differentially-expressed miRNAs (all down-regulated) and 900 mRNAs were identified, mostly involved in the negative regulation of protein binding, DNA binding, or transcription in the cell cycle. Ten core genes were screened out: MAPK1, TP53, MAPK14, CCND1, EP300, POLR2E, POLR2F, ABL1, RAC1 and SKIV2L2.Conclusions:Multiple miRNAs, target genes and signaling pathways are involved in the development of OA. The miRNA-mRNA regulatory network identified provides new ideas for exploring the molecular mechanism of OA′s pathology and its clinical diagnosis and treatment.

The Zika virus (ZIKV) and dengue virus (DENV) flaviviruses exhibit similar replicative processes but have distinct clinical outcomes. A systematic understanding of virus–host protein–pro-tein interaction networks can reveal cellular pathways critical to viral replication and disease patho-genesis. Here we employed three independent systems biology approaches toward this goal. First, protein array analysis of direct interactions between individual ZIKV/DENV viral proteins and 20,240 human proteins revealed multiple conserved cellular pathways and protein complexes, including proteasome complexes. Second, an RNAi screen of 10,415 druggable genes identified the host proteins required for ZIKV infection and uncovered that proteasome proteins were crucial in this process. Third, high-throughput screening of 6016 bioactive compounds for ZIKV inhibition yielded 134 effective compounds, including six proteasome inhibitors that suppress both ZIKV and DENV replication. Integrative analyses of these orthogonal datasets pinpoint proteasomes as crit-ical host machinery for ZIKV/DENV replication. Our study provides multi-omics datasets for fur-ther studies of flavivirus–host interactions, disease pathogenesis, and new drug targets.

Objective:To summarize the clinical characteristics and the features of electroencephalograph (EEG) of children with DEPDC5 gene variants related epilepsy.Methods:The clinical data, gene variation, EEG and head magnetic resonance image (MRI) of 20 epileptic children with DEPDC5 gene variants admitted to Department of Pediatrics, Peking University First Hospital from May 2017 to November 2020 were retrospectively analyzed.Results:Twenty patients with heterozygous DEPDC5 gene variants were enrolled, 8 of 20 patients were nonsense variants, 6 were missense variants, 3 were frame-shift variants, 2 were splicing variants, and 1 was large fragment deletion. Sixteen cases had hereditary variation and 4 had de novo variation. Fifteen of variations were novel. Nine were male, while 11 were female. Their latest follow-up age ranged from 10 months to 13 years and one month.The epilepsy onset age ranged from 3 hours to 11 years and 3 months, the median age was 10.5 months. Twelve (60%) patients had developmental delay. Nineteen patients had focal seizures, 7 had epileptic spasms, 1 had multiple seizure types including tonic, atypical absence, dystonic and myoclonic seizures. Epileptic form discharges were observed in 18 patients during the interictal phase, and 11 were focal discharges, 7 were multifocal discharges. Ten (50%) patients had abnormal brain MRI, including focal cortical dysplasia in 5 patients, undefined malformation of cortical development in 4 patients, hemimegalencephaly in 1 patient. Four patients were diagnosed as West syndrome and one patient was diagnosed as Lennox-Gastaut syndrome. Fourteen (70%) patients were diagnosed as drug-resistant epilepsy. Four patients became seizure-free by treatment with anti-epileptic drugs. Three children were treated with surgery, and 2 of them became seizure-free, 1 had more than 75% reduction in seizures.Conclusions:DEPDC5 gene variant epilepsy is inherited with incomplete penetrance and focal seizure is the major seizure type. However, epileptic spasms, generalized seizures can also be observed. Half of the patients brain malformations. Most of the patients are drug-resistant epilepsy. Patients with clear epileptogenic zones can be treated with surgery. Treatment-resistant patients are more likely to be complicated with developmental delay.

OBJECTIVES:
To verify the applicability and extensibility of the satisfaction index of basic medical insurance for rural and urban residents, and to explore the mechanism responsible for the satisfaction index in Kunming and Changsha City, and provide references for effective management and policy making.
METHODS:
A stratified cluster sampling method was conducted. A total of 560 familial decision makers were randomly selected in 24 classes of 14 schools of Kunming and Changsha City. Model reliability was tested by SPSS18.0. In addition, Smart PLS 3.0 was applied to conduct model validity test, calculate the satisfaction index, and to compare the model path coefficients of Kunming and Changsha by multi-group analysis.
RESULTS:
In the application of the satisfaction index of basic medical insurance for rural and urban residents in Kunming, Cronbach's α of the model was 0.93, split-half reliability coefficient was 0.90, and the latent variable composite reliability coefficient values were more than 0.86; the latent variable average variance extraction (AVE) values were greater than 0.66, and the square root of the AVE of each latent variable (all greater than 0.66) was larger than the correlation coefficient with other latent variables. The factor loading values were greater than 0.70, with statistical significance. The basic health insurance satisfaction index of Kunming and Changsha was 60.40 and 52.05, respectively. The difference between the path coefficient of Kunming and Changsha was not statistically significant except the path from public satisfaction to public loyalty. Perceived value had the largest direct and total effect on public satisfaction latent variable in Kunming City. While the perceived value had the largest direct effect on public satisfaction, and the perceived quality had the largest total effect on public satisfaction in Changsha City.
CONCLUSIONS
The satisfaction index model reflects the satisfaction of pupils' basic medical insurance for urban and rural residents, and it also shows good reliability and validity in Changsha and Kunming. What's more the model can be extended to the national level to evaluate the satisfaction of basic medical insurance for urban and rural residents for primary school students. The basic health insurance satisfaction index of familial decision makers in Kunming is higher than that of Changsha. There are differences between Kunming and Changsha in the influential mechanism of the satisfaction index of for Chinese pupils with basic medical insurance for rural and urban residents, and the measures taken by the government and relevant departments to improve the satisfaction of basic medical insurance should be based on local conditions.
