Objective To investigate the effect of interleukin-1β (IL-1β) on the expression of synaptic protein SNAP-25 in the hippocampus in septic neonatal rat induced by systemic lipopolysaceharide (LPS) injection.Methods Sprague-Dawley (SD) rats were randomly divided into two groups:control group and sepsis group.The rat model of sepsis was produced by intraperitoneal injection of 1 mg/kg LPS,and rats in the control group were injected with an equal volume of 0.01 mol/L phosphate buffered saline (PBS).The expression levels of IL-1β and IL-1R1 in the hippocampus at 1,2 and 3 d,and synaptosomal-associated protein 25 (SNAP-25) at 7,14 and 24 d after LPS intraperitoneal injection were detected by Western blot.After cultured for 24 h,primary hippocampal neurons were divided into four groups including the control group,IL-1β (40 ng/mL) treatment group,IL-1β (40 ng/mL) + IL-1Ra (40 ng/mL) treatment group,and IL-1Ra (40 ng/mL) treatment group.The effect of IL-1β on SNAP-25 expression in primary hippocampal neuron was determined by Western blot and real-time PCR.The purity of hippocampal neurons were identified by NeuN immunofluorescence staining and the activity of neurons were detected by CCK-8 assay.All data were analyzed by SPSS version 22.0.The data were analyzed by student-t test and Dunnett-t test.The interaction effects were analyzed by factorial ANOVA.Differences were considered to be statistically significant if P＜ 0.05.Results Compared with the control group,the expressions of IL-1β and IL-1R1 were significantly increased in the hippocampus at 1,2 and 3 d after intraperitoneal injection of LPS (P＜0.05).The expression of SNAP-25 protein was decreased at 7,14,and 28 d after intraperitoneal injection of LPS (P＜0.05).The purity of primary neurons was about up to 92％.The activity of primary neurons was not relatively changed after treated with IL-1β at a dose less than 40 ng/mL.The level of SNAP-25 protein was obviously decreased in primary neurons at 24 h after IL-1β treatment (P＜0.05).IL-1Ra treatment might reverse the effect of IL-1β on primary neurons (P＜0.05).While,the expression of SNAP-25 mRNA was not statistically different in each group (P＞0.05).Conclusions IL-1β may possibly inhibit the expression level of SNAP-25 protein in the hippocampus in the septic rats through its receptor IL-1R1,which would contribute to cognitive dysfunction of septic neonatal rats in later life.

OBJECTIVETo investigate EXT1 and EXT2 genes mutations in a family with hereditary multiple osteochondromas (HME).

METHODSA four-generation family with HME from Linyi city of Shandong Province was studied. There were 6 affected individuals among the 17 family members. Physical examination and radiographical evaluations were carried out for all family members. Genomic DNA was extracted from peripheral venous blood and the samples were subjected to mutation screening by PCR of the coding regions of EXT1 and EXT2 genes.

RESULTSThe family has featured an autosomal dominant inheritance pattern. Sequencing of the EXT1 and EXT2 genes suggested the causative gene in this family was in linkage with the second exon of EXT2. A c.244delG mutation was detected, which has resulted in a frameshift mutation p.Asp81IlefsX30. The mutation was found in all of the 6 affected individuals but not in normal family members. And the mutation has co-segregated with the phenotype.

CONCLUSIONThe mutation c.244delG in the EXT2 gene is the probably the cause of the disease in this family.

OBJECTIVE: To explore the genetic basis for two patients from a family with BCL11A-related intellectual disability (BCL11A-ID). METHODS: Clinical data of the proband and her family members was analyzed. Chromosomal karyotyping analysis, trio-whole exome sequencing (trio-WES) and copy number variation sequencing (CNV-seq) were carried out. For the suspected genetic variants, Sanger sequencing was used to verify, and pathogenicity assessment was conducted. RESULTS: The proband and her mother both had intellectual and language impairment, and their fetal hemoglobin (HbF) was significantly elevated. A heterozygous c.1327_c.1328delTC (p.Ser443Hisfs*128) variant was found in exon 4 of the BCL11A gene by WES, which has resulted in truncated expression of the encoded protein, and Sanger sequencing has verified that the variant was inherited from the mother. The variant was not found in related databases. The variant was predicted as pathogenic according to the guidelines from the American College of Medical Genetics and Genomics (ACMG) (PVS1+PM2+PP1). No karyotypic abnormality was found in the proband, her parents and brother, and no pathogenic CNVs was found in the proband and her parents. CONCLUSION The c.1327_c.1328delTC (p.Ser443Hisfs*128) variant may underlay the BCL11A-ID in the proband and her mother. This de novo variant has expanded the mutational spectrum of the BCL11A gene.

Objective To systematically evaluate the effect of speech and language therapies and educational interventions on chil-dren with intellectual and developmental disabilities(IDD). Methods A systematic review was conducted by searching relevant literature in PubMed,PsycINFO,ERIC,Cochrane Library and Web of Science databases,ranging from January,2018 to May,2024. Results A total of eight English articles were included,from six countries including the United States,France,Italy,Nor-way,Poland and New Zealand,involving 610 children with IDD,from journals about speech language pathology,Down syndrome research and speech language hearing research.The publication time was mainly from 2018 to 2023.The age of the subjects was two to twelve years,and the main health conditions included intellectual dis-ability,autism and Down syndrome.The intervention methods included routine speech therapy(individualized therapy and group therapy),augmentative and alternative communication(device-assisted and sign language and picture cards),family-involved language training programs(parent training and family interaction),computer-as-sisted language learning(language learning software and telehealth),and play-based interventions(interactive games and structured games);15 to 150 minutes a time,one to ten times a week,for ten to 144 weeks.The out-comes were reflected in five aspects:increasing the vocabulary in speaking;improving the language comprehen-sion,symbol recognition and vocabulary comprehension;improving both expressive and receptive language skills;improving participation in game diversity and game participation levels,communication,social interaction and interaction skills;and improving overall language and non-verbal communication skills. Conclusion Combining a variety of methods,such as individualized therapy,family participation,technologic assistance and interactive games,speech and language therapies and education are effective on spoken language production,language comprehension,speech production,social interaction and communication skills for children with IDD.

OBJECTIVETo assess the association of coagulation factor V gene polymorphisms with unexplained recurrent spontaneous abortion (URSA) among ethnic Han Chinese from Wenzhou area.

METHODSNinety-six patients with URSA and 103 females with a history of normal pregnancy were recruited. Genotypes of coagulation factor V gene were determined through target sequence capture and high-throughput sequencing. The results were confirmed with a MassARRAY system. Allelic and genotypic frequencies between the two groups were compared.

RESULTSNineteen single nucleotide polymorphism (SNPs), except coagulation factor V Leiden, were identified in the two groups. The frequencies of rs9287090 allele A, rs1046712 allele T and rs1800594 allele G of the URSA group were lower than those of the control group (6.77% vs. 16.50%, 3.12% vs. 13.11%, 10.94% vs. 18.45%, respectively). After Bonferroni and false discovery rate correction, rs9287090 and rs1046712 were significantly associated with URSA (corrected P<0.05). Although genotypic distribution of rs9287090 and rs1046712 also differed between the two groups, the corrected P value showed no significance (corrected P>0.05). A complete linkage disequilibrium (r=1, D'=1) of rs6022 and rs6029 was observed for the haplotype block rs6022-rs6029-rs6028. The frequencies of rs6022 allele A and rs6029 allele T were higher in the URSA group with corrected insignificance (75.00% vs. 65.53%, corrected P>0.05). Furthermore, significantly more A-T-T haplotype was found in the URSA group (75.00% vs. 65.50%, OR=1.578, 95%CI:1.021-2.438, χ=4.248, P<0.05).

CONCLUSIONThe decreased rate of rs9287090 allele A, rs1046712 allele T, and rs1800594 allele G may contribute to the susceptibility to URSA among ethnic Han Chinese from Wenzhou area. The rs6022 allele A and rs6029 allele T may also predispose to URSA.

Objective:To explore the genotype and clinical phenotype characteristics of patients with pancreatic agenesis caused by GATA6 gene mutations and to improve the clinical understanding of pancreatic agenesis.Methods:The clinical data of a newborn with pancreatic agenesis admitted to the Second Hospital of Shandong University were retrospectively analyzed. Relevant literature published until October 31, 2022, were retrieved from China National Knowledge Infrastructure, Wanfang Database, VIP Database, Chinese Medical Journal Full Text Database, PubMed, Embase and SCI Database with the terms of "pancreatic agenesis", "GATA6", "pancreatic agenesis/hypoplasia" and "GATA6 Translation Factor". The characteristics of gene variants and clinical manifestations of patients diagnosed with pancreatic agenesis caused by GATA6 gene mutation were retrieved and summarized.Results:This case was a full-term male infant who developed insulin dependent hyperglycemia and fatty diarrhea 2 d after birth, accompanied by intrauterine growth restriction, congenital heart disease, and cryptorchidism. Genetic testing showed a novel heterozygous mutation of GATA6 (c.1366C>T) which was consistent with the autosomal dominant inheritance pattern. The phenotype and genotype between the proband and his parents were consistent with the cosegregation. The ACMG mutation was rated as pathogenic variant. Intravenous infusion of insulin, subcutaneous injection of insulin, or long-acting insulin were not effective. After continuous subcutaneous pumping of aspartic insulin combined with oral pancreatic enzyme replacement therapy, the infant's condition was improved and discharged. Follow up to age of 15 months, the patient still relied on continuously subcutaneous pump to control blood glucose, pancreatic exocrine function was back to normal, and the development was generally normal. A total of 59 cases were reported in 22 articles, with the case from our hospital, there were 60 patients in total. Among them, 47 were probands and 13 were family members, about 61.7% (29/47) of which were de novo mutations. There were 39 variants, of which 28.2% (11/39) were missense mutations and 71.8% (28/39) were functional deletion variations. Mutations of GATA6 gene had a broad phenotype spectrum. The phenotypes mainly included neonatal diabetes mellitus ( n=39) and pancreatic exocrine insufficiency ( n=39). Other extra-pancreatic features included different types of congenital heart disease ( n=54), congenital biliary abnormalities ( n=23), intestinal developmental disorders ( n=16), neurocognitive disorders ( n=18) and endocrine abnormalities ( n=15). Conclusions:The heterozygous variations of GATA6 gene lead to pancreatic hypoplasia and a broad phenotype spectrum. The pancreatic phenotypes mainly include neonatal diabetes mellitus and pancreatic exocrine insufficiency, and extra-pancreatic phenotypes include congenital heart disease and other developmental abnormalities.

ObjectiveTo analyze the sequence variation and genetic diversity of 47 Isatis indigotica germplasm materials， and carry out the study on the genetic differentiation and structure. MethodGenomic DNA of 47 I. indigotica germplasm materials were extracted by kit extraction method. Two chloroplast DNA （cp DNA） sequences and five inter-simple sequence repeat （ISSR） primers were used for amplification and sequencing. Chromas， Mega 7.0， DanSP5， and GenALEx were used to calibrate， splice， and analyze the sequence characteristics. PERMUT and PopGen 1.31 were used to analyze the genetic diversity parameters and genetic structure， and NTSYS was used to obtain the unweighted pair-group method with arithmetic means（UPGMA） clustering tree plot of 47 I. indigotica germplasm materials. ResultA total of 129 samples from 47 I. indigotica germplasm materials were successfully amplified and sequenced. The length of 2 cp DNA sequences after spliced was 1 412 bp， and there were 377 polymorphic variation loci， and 36 haplotypes. Fu and Li's D* test was significant （P<0.01）. The values of Pi， H_S， and H_T based on cp DNA were 0.119 89， 0.787， and 0.891， respectively. The genetic differentiation coefficients of gene differentiation coefficient（Gst）， nucleotide differentiation coefficient（Nst）， and fixation index（Fst） were 0.117， 0.468， and 0.488， respectively， and the gene flow （Nm） was 0.615. The mean values of PPB， Shannon information diversity index（I）， Nei's genetic diversity index（H）， and Gst based on ISSR were 78.85%， 0.334 8， 0.218 6， and 0.754 4， respectively， and the Nm value was 0.162 8. ConclusionI. indigotica has high genetic diversity and abundant haplotypes at the species level， with abundant haplotypes. Genetic differentiation among different germplasm materials is obvious， and gene exchange is not frequent. Genetic variation mainly exists among populations. The population has accumulated various low-frequency gene mutations recently， suggesting that it has experienced significant regional expansion in the history.

The coronavirus disease 2019 (COVID-19) pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is spread primary via respiratory droplets and infects the lungs. Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines (transformed or cancer cells) and species differences between animals and humans. Organoids are stem cell-derived self-organized three-dimensional culture in vitro and model the physiological conditions of natural organs. Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells (hESCs)-derived lung organoids, including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs. The infected cells were ciliated, club, and alveolar type 2 (AT2) cells, which were sequentially located from the proximal to the distal airway and terminal alveoli, respectively. Additionally, RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes, especially lipid metabolism, in addition to the well-known upregulation of immune response. Further, Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids. Therefore, human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
