Autism spectrum disorder (ASD), also known as autism, is a series of neurodevelopmental disorders characterized by social disorders and repetitive stereotyped behaviors/narrow interests. Its pathogenesis is complex, and there is a lack of effective treatment drugs, with some cases having adverse outcomes. Recent studies have consistently revealed that individuals with autism spectrum disorder (ASD) commonly exhibit characteristics such as gut microbiota dysbiosis (abnormal Bacteroidetes/Firmicutes ratio), impaired intestinal barrier function (elevated serum levels of zonulin and LPS), and intestinal immune dysregulation (increased pro-inflammatory cytokines including IL-6 and TNF-α), suggesting that gastrointestinal abnormalities may influence central nervous system development through neuroendocrine, immunoregulatory, and metabolic pathways. Consequently, growing scholarly attention has focused on dietary interventions as potential approaches to alleviate clinical symptoms in children with ASD. This review systematically summarizes the role of gut microbiota and their metabolite alterations in ASD pathogenesis, along with recent advancements in understanding the microbiota-gut-brain axis mechanisms. Additionally, it elaborates on the therapeutic effects and underlying biological basis of restrictive diet therapy, modified diet therapy, and nutritional supplementation therapy in promoting the health of children with ASD. This systematic review reveals that children with ASD exhibit significant gut microbiota dysbiosis (e.g., increased Clostridium, decreased Faecalibacterium) and abnormal metabolite profiles (e.g., altered short-chain fatty acid spectra, elevated 4EPS levels). These alterations exacerbate neuroinflammation and immune dysregulation through the microbiota-gut-brain axis, thereby impacting nervous system development and function. Furthermore, interventions such as ketogenic diets, camel milk, and specific nutritional supplements can alleviate certain ASD symptoms by modulating gut microbiota, restoring intestinal barrier function, and improving metabolic pathways. Future investigations should aim to create multi-omics evaluation systems for pinpointing potential beneficiaries, devise individualized intervention strategies rooted in microbiome characteristics, and verify their therapeutic value and safety in large-scale randomized controlled trials. These efforts are crucial to transitioning ASD treatment from symptomatic control to address disease etiology, thereby paving the way for improving prognoses.

ObjectiveTo construct a stable monoclonal human embryonic kidney 293 (HEK293) cell line expressing recombinant human coagulation factor Ⅶ (rhFⅦ) and evaluate the expression level and procoagulant bioactivity of rhFⅦ. MethodsThe plasmid pCDNA3.1-EGFP-FⅦ was transfected into HEK293 cells to verify the effectiveness of the transfection system. The plasmid pCDNA3.1-FⅦ was transfected into HEK293 cells, and monoclonal stable transfected cell lines were selected using geneticin (G418). The transcription of the FⅦ gene was identified by reverse transcription polymerase chain reaction (RT-PCR). The expression level of rhFⅦ in the supernatant of the monoclonal stable transfected cell line was detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot. The concentration of rhFⅦ was determined by enzyme-linked immunosorbent assay (ELISA), and the procoagulant activity of rhFⅦ was measured by human coagulation factor Ⅶ potency assay. ResultsHEK293 cells transfected with pcDNA3.1-EGFP-FⅦ showed green fluorescence, indicating that rhFⅦ was successfully expressed in the supernatant of HEK293 cells after transient transfection with pcDNA3.1-FⅦ. The monoclonal stable transfected cell line was obtained by G418 screening. RT-PCR identified that the FⅦ gene was integrated into the genome of the monoclonal stable transfected cell line. The cell viability was good as detected by Cell Counting Kit-8, and a single band of rhFⅦ was obtained by purification of the cell supernatant. The highest rhFⅦ expression was (1.27±0.09) mg/L, and the highest procoagulant activity was (380.29±13.80)%. ConclusionThe monoclonal HEK293 cell lines which can express rhFⅦ protein efficiently and stably with excellent procoagulant bioactivity is successfully screened.

Chinese Journal of School Health 2026;47(3):408-412
Objective:
To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation.
Methods:
Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method.
Results:
Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years.
Conclusion
Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

Objective:To analyze by bioinformatics the association between the expression of membrane-associated tyrosine/threonine protein kinase 1(PKMYT1)in glioma with its prognostic value,biological function,drug sensitivity,gene mutation,and immune infiltration.Methods:The differential expression of PKMYT1 was analyzed based on the Chinese Glioma Genome Atlas database(CGGA)and the Cancer Genome Atlas database(TCGA).Pathways likely to be enriched for PKMYT1 were predicted by gene ontology analysis(GO)and gene set enrichment analysis(GSEA).PKMYT1 was subjected to Pearson correlation and gene set variation analysis(GSVA)with cell cycle-related genes and gene sets.The survival prognosis,gene mutation,drug sensitivity and immune infiltration were further analyzed for PKMYT1 high and low expression groups of glioma patients.Results:PKMYT1 was significantly highly expressed in WHO high-grade glioma(P<0.000 1),IDH wild-type glioma(P<0.05),and glioblastoma(P<0.000 1).Overall survival(OS)of patients in the PKMYT1 low expression group was significantly higher than that of the high expression group(P<0.05).Cox regression analysis showed that PKMYT1 expression level was an independent prognostic factor for OS(P<0.05).GO and GSEA analyses showed that the gene sets co-expressed with PKMYT1 were mainly enriched in signaling pathways such as cell cycle,DNA replication and DNA damage repair.Pearson correlation and GSVA analyses showed that the expression of PKMYT1 was significantly and positively correlated with the cell cycle-related genes,gene sets and cell cycle checkpoint genes(P<0.01).Drug sensitivity analysis revealed that patients in the PKMYT1 high expression group had high sensitivity osimertinib,dabrafenib,carmustine and cediranib(P<0.05).Mutation analysis revealed that the IDH1 gene had a higher mutation frequency in the PKMYT1 low expression group.The results of immune infiltration analysis showed that PKMYT1 expression was significantly positively correlated with glioma stroma score(r=0.13,P<0.001),immune score(r=0.11,P<0.01)and ESTIMATE score(r=0.13,P<0.001);and was significantly positively correlated with immune cell infiltration level of regulatory T(Treg)cells and M2-type macrophages(P<0.05).Conclusion:Patients with high PKMYT1 expression have a poorer prognosis,and the mechanism may be related to tumor immune infiltration and cell cycle regulation.PKMYT1 is expected to be a potential target for the diagnosis and treatment of glioma.
