Inflammatory bowel disease (IBD) is a chronic inflammatory disease that occurs in the gastrointestinal tract and adversely affects the quality of life of patients and the healthcare burden on society. Currently, drug therapy alone can achieve clinical remission in some patients, but it cannot break through the ceiling of what can be achieved with current therapies, and new therapeutic options still need to be found. Neuro-immunity-inflammation is closely related to each other, and the potential role of neuroelectric stimulation in modulating inflammatory response has made it a hot spot in the study of IBD treatment. However, the intrinsic mechanism of action is still unexplained and needs to be explored by further studies. This review discusses the role and mechanisms of vagus nerve electrical stimulation, sacral nerve electrical stimulation, tibial nerve electrical stimulation and other neuromodulation methods.

OBJECTIVE:
To explore the clinical features and genetic etiology of a child with a SETD1B gene variant causing seizures and language delay.
METHODS:
A child with a SETD1B gene variant admitted to the Department of Pediatric Neurology at the Third Affiliated Hospital of Zhengzhou University in September 2022 was selected as the study subject. Clinical data of the child were collected, and peripheral blood samples from the child and her parents were obtained. Whole exome sequencing (WES) was performed for genetic testing, and Sanger sequencing was used for familial validation of the candidate variant. Using "SETD1B" and "epilepsy" as the Chinese and English keywords, relevant cases were retrieved from databases including CNKI, Wanfang Data, OMIM and PubMed, with the search period spanning from database inception to June 2024.
RESULTS:
The child was a 6-year-old female presenting with myoclonic seizures accompanied by global developmental delay. WES and Sanger sequencing revealed that the child has carried a de novo SETD1B gene variant, namely c.5582G>A (p.Cys1961Tyr). According to the American College of Medical Genetics and Genomics (ACMG) guidelines for sequence variant interpretation, this variant was classified as likely pathogenic (PS2+PM2_Supporting+PP2+PP3). The child was not controlled with effective doses of valproate, levetiracetam, or clonazepam but was successfully managed with low-dose lamotrigine. Follow-up electroencephalography showed normal results, and developmental progress gradually improved. A total of 37 epilepsy cases with SETD1B gene variants were reported across six studies. The predominant seizure types included absence seizures and myoclonic absence seizures, accompanied by delayed language development. The response to pharmacological treatment was generally poor, with no significant difference in incidence between males and females.
CONCLUSION
SETD1B gene variants may cause neurological disorders with drug-resistant epilepsy and severe clinical manifestations. Lamotrigine is effective in controlling the epileptic seizures.

OBJECTIVE:
To analyze the clinical characteristics and genotypic changes of six children with RARS2 gene variants.
METHODS:
The clinical data of 6 children with RARS2 gene variants diagnosed at the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2024 were collected. Genetic variants were detected using trio-whole exome sequencing. Genomic DNA was extracted from samples and subjected to high-throughput sequencing. Variants were detected and analyzed using relevant databases and software. Pathogenic variants were validated by Sanger sequencing. The protein structure encoded by a previously unreported variant was predicted using a SWISS-MODEL online server. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2024-373-01).
RESULTS:
Among the six children, four were males and two were females, with the most recent follow-up age ranging from 1-year-and-1-month to 7 years old. The age of onset was under 1 year in all cases. All six children exhibited seizures, including infantile spasms in three, spasms and tonic spasms in one, and focal seizures in two. One child became seizure-free for 4 ~ 5 years following Valproic acid combined with topiramate and adrenocorticotropic hormone (ACTH) pulse therapy, but subsequently experienced a relapse. Another child has remained seizure-free for nearly one year with oral sodium valproate, levetiracetam, and a "cocktail" therapy. Seizures were not controlled in the remaining four children. Pontocerebellar hypoplasia was observed on neuroimaging in two children. All six patients exhibited severe psychomotor retardation. A total of 10 RARS2 gene variants were identified, three of which were previously unreported.
CONCLUSION
The predominant clinical features of Pontocerebellar hypoplasia associated with RARS2 gene variants include infantile onset, severe psychomotor retardation or regression, drug-resistant epilepsy, and feeding difficulties. The characteristic neuroimaging finding is pontocerebellar hypoplasia. However, its appearance may vary widely with time. The majority of affected children have a poor prognosis.

OBJECTIVE:
To explore the clinical and genetic characteristics of a child with intellectual development disorder and seizures due to a variant of AP2M1 gene.
METHODS:
Clinical data of a child with intellectual development disorder and epilepsy who was admitted to the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University in January 2021 were retrospectively analyzed. Peripheral blood samples of the child and his parents were collected for whole exome sequencing. Candidate variant was verified by Sanger sequencing and pathogenicity analysis. The three-dimensional structure of the AP2M1 protein was visualized using Chimera v1.10.1 software. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants from the American College of Medical Genetics and Genomics American College of Medical Genetics (ACMG). With "AP2M1 gene" "epilepsy" "intellectual disability" as the keywords, relevant cases were searched from CNKI, Wanfang Data knowledge service platform and PubMed databases with the search time spanning from the establishment of the database to September 2024. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2020-57).
RESULTS:
The child was a 8-years-and-6-months-old boy, who could raise his head at 3 months and sit alone at 8 months old. He could not walk alone at 1 year old and underwent 2 months' rehabilitation treatment, and could walk alone and call his parents at 1-and-a-half-years-old. At 4-years-and-10-months-old, he started to have frequent seizures, manifesting as low level of consciousness, body shaking, accompanied by blinking, lasting about a few seconds several times a day and could be relieved. With the treatment of sodium valproate combined with lamotrigine, the convulsions were controlled, but his movement and cognition were lagged behind. DNA sequencing revealed that he has harbored a novel variant of the AP2M1 gene (NM_004068.3) c.508C>T (p.Arg170Trp). Sanger sequencing confirmed that both of his parents were of the wild-type. According to the guidelines from the American College for Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PS2+PS4+PM1+PM2+PP2+PP3). The difference between the wild-type and mutant AP2M1 proteins can be clearly viewed through its three-dimensional structure. Two previous reports have included 5 cases due to the same variant. Common manifestations have included seizures (100%, 5/5), motor retardation (100%, 5/5), intellectual impairment (100%, 5/5), autism spectrum disorder (60%, 3/5), ataxia (100%, 5/5), and special facial features (20%, 1/5).
CONCLUSION
The c.508C>T (p.Arg170Trp) variant of the AP2M1 gene may underlie the intellectual retardation and seizure in this child.

OBJECTIVE:
To explore the clinical phenotype and genetic characteristics of a child with Progressive familial intrahepatic cholestasis type 8 (PFIC8). METHODS A child with PFIC diagnosed at Beijing Children's Hospital Affiliated to Capital Medical University in September 2025 was selected as the study subject. Peripheral venous blood samples were collected from the child and her parents. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was classified based on the guidelines from American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Beijing Children's Hospital Affiliated to Capital Medical University (Ethics No.: 2023-E-126-Y).
RESULTS:
The proband, a 2-month-old female infant, had manifested jaundice of the skin and sclera, and slightly distended abdomen. She had no visible abdominal wall varicose veins, soft abdomen, and no palpable masses. Biliary atresia was ruled out by intraoperative cholangiography. WES revealed that she has harbored compound heterozygous variants of KIF12 gene, namely c.809C>T (p.Ala270Val) and c.1313G>A (p.Arg438Lys), which were verified by Sanger sequencing to have derived from her mother and father, respectively. According to the ACMG guidelines, both variants were classified as variants of uncertain significance (VUS). Based on the pre-defined search strategy, 10 articles were retrieved, which involved 25 PFIC cases, including 5 from China. Together with the proband of this study, the 26 PFIC patients have primarily presented with high GGT cholestasis, with the genetic cause in all cases attributed to variants of the KIF12 gene.
CONCLUSION
The c.809C>T and c.1313G>A compound heterozygous variants of the KIF12 gene probably underlay the pathogenesis of cholestatic liver disease in this child. Above findings have enriched the mutational and phenotypic spectra of PFIC8.

Objective To provide technical support for the formulation of scientific and reasonable supervision measures for enterprises engaged in the exploitation and utilization of ores with associated radionuclides in Guangxi Province, China. Methods A radionuclide analysis was performed on solid materials generated during production processes such as zirconium-titanium ore dressing and processing in multiple enterprises in Guangxi Province. The radiation levels of effluents was measured. Measurement and analysis were performed on the environmental air radon concentration levels and environmental γ-radiation dose rates at the factory boundaries of these enterprises and the surrounding environmental protection targets. Results The air absorption dose rate of γ radiation, the concentrations of radon and its daughters, and the radiation levels of surface water and aerosols at the factory boundaries and in the surrounding environment were all at normal levels. The specific activities of nuclides 238U, 232Th, and 226Ra in the raw ore, zirconium products, rutile products, and monazite products within the factory area were relatively high. The γ radiation air absorption dose rates in the corresponding workshops were also relatively high, with the zirconium-rutile workshop being the area with the highest values. Materials such as zirconium products, rutile, and monazite all showed a certain amount of radon exhalation. Conclusion The radiation level of tailings met the criteria of monitoring exemption, and the enterprises did not generate radioactive solid waste. Attention should be paid to the personal dose of the staff in areas with high radiation dose rates.

Objective To investigate the effect and underlying mechanism of miR-137 on athero-sclerosis(AS)plaques in apolipoprotein E(ApoE)gene knockout(ApoE)mice.Methods Sixty ApoE-/-mice were fed with high-fat diet for 12 weeks to establish an AS model.Then they were assigned into AS group,negative control group,miR-137 group,Ad negative control group,and combination group,with 12 mice in each group;Another 12 wild-type C57BL/6 mice fed with chow diet were subjected as the Control group.Fully automated biochemical analyzer was applied to detect serum lipid levels,including total cholesterol(TC),triglycerides(TG),low-density lipo-protein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C).ELISA was con-ducted to detect the levels of serum inflammatory factors,including TNF-α,IL-4,IL-6,and IL-10.HE staining was used to observe the morphological changes of mouse aortic tissue.Oil red O stai-ning was employed to observe the overall formation of aortic plaques.Immunofluorescence stai-ning was utilized to detect the expression of inducible nitric oxide synthase(iNOS)and arginase-1(Arg-1)in the aortic tissue.Real-time qPCR was applied to detect the mRNA expression of miR-137 and sex determining region Y box protein 4(SOX4)in the aorta.Results The miR-137 group has significantly lower serum levels of TG,TC,LDL-C,TNF-α and IL-6,and higher levels of HDL-C,IL-10 and IL-4 when compared with the AS group and negative control group(P<0.05).The combination treatment resulted in increased serum levels of TG,TC,LDL-C,TNF-αand IL-6,while decreased levels of HDL-C,IL-10 and IL-4 in comparison with the Ad negative control group(P<0.05).Larger aortic plaque area,more severe overall aortic plaque injury and stronger iNOS fluorescence intensity were observed in the AS group than the control group(P<0.05).Treatment of miR-137 reversed above histological changes,resulting in smaller aortic plaque area,attenuated overall aortic plaque injury,decreased iNOS fluorescence intensity,and elevated Arg-1 fluorescence intensity when compared with the AS group and negative control group(P<0.05).Compared with the Ad negative control group,the aortic plaque area,overall aortic plaque injury and iNOS fluorescence intensity were increased,while the Arg-1 fluorescence intensity was significantly decreased in the combined group(P<0.05).Double luciferase assay showed that the luciferase activity of SOX4-containing wild-type cells was significantly decreased after transfection of miR-137 mimics when compared with transfection of mimics negative control(0.37±0.05 vs 1.00±0.08,P<0.05).Conclusion Overexpression of miR-137 inhibits the activa-tion of rat sarcoma/mitogen-activated protein kinase pathway probably by down-regulating SOX4 expression,and then suppress M1 macrophage polarization and promote M2 macrophage polariza-tion,reduces inflammatory response and the formation of AS plaques.
