Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective To investigate the effects of governor vessel pushing manipulation on behavioral outcomes in valproic acid(VPA)-induced autism spectrum disorder(ASD)rats and explore its underlying mechanisms using prefrontal RNA sequencing(RNA-Seq).Methods Nine Sprague-Dawley pregnant rats at gestational day 12.5 were divided into two groups,six received intraperitoneal VPA injection(600 mg/kg)for modeling,and three received saline.Male offspring at postnatal day 21 were evaluated using the three-chamber social test and open field test to validate the ASD model.VPA-induced male offspring were randomly assigned to the model group(n=5)or tuina group(n=5),while saline offspring formed the blank group(n=5).The blank group and model group received no intervention,while the tuina group underwent governor vessel pushing manipulation stimulation along the governor vessel using a custom device,twice a day for 14 days,totaling 28 times.Post-intervention,behavioral assessments included social index(SI)and social preference index(SPI)in the three-chamber test,total distance traveled and central zone time in the open field test,marble-burying test for stereotyped behaviors,and Nissl staining for prefrontal cortical neuron survival.RNA-Seq identified differentially expressed genes(DEGs)in the prefrontal cortex,followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.Real time fluorogenic quantitative PCR(RT-qPCR)validated DEGs,and Western blotting analyzed proteins in enriched pathways.Results Pre-intervention,both model and tuina groups showed reduced SI,SPI,total distance,and central zone time compared to the blank group(P<0.05),confirming successful modeling.Post-intervention,the model group exhibited lower SI,SPI,total distance,central zone time,increased marble-burying(P<0.05),and fewer Nissl bodies(P<0.01)versus the blank group.Compared to the model group,the tuina group displayed improved SI,SPI,total distance,central zone time(P<0.05),reduced marble-burying(P<0.05),and increased Nissl bodies(P<0.01).RNA-Seq revealed 213 prefrontal DEGs(181 upregulated,32 downregulated)in the tuina group.GO analysis highlighted cellular components,while KEGG identified 181 pathways,with 67 significantly enriched(P<0.05),notably the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)pathway.RT-qPCR confirmed decreased collagen type Ⅰ alpha 2(Col1α2),transforming growth factor-α(TGF-α),epidermal growth factor receptor 3(ErbB3),and serum/glucocorticoid regulated kinase 2(Sgk2)(P<0.05),and increased hepatic growth factor(Hgf)(P<0.01)in the model group,reversed by governor vessel pushing manipulation.Western blotting showed reduced prefrontal NRG1,ErbB3,nNOS,PI3K,AKT,p-nNOS,p-PI3K,and p-AKT in the model group(P<0.05),which were upregulated by tuina.Conclusion Governor vessel pushing manipulation ameliorates social deficits,anxiety,stereotyped behaviors,and neuronal loss in ASD rats,potentially via activation of the PI3K/AKT signaling pathway.

Research shows that epileptic seizures are essentially due to abnormal functions of neural circuits. Optogenetics regulates neural circuits by specifically expressing light-sensitive proteins in target neurons, which has now become an important tool in the research of temporal lobe epilepsy. Studies have shown that optogenetics focuses on brain regions such as the hippocampus, medial septal nucleus, cerebellum, and basal ganglia in studying temporal lobe epilepsy. This article reviews the research progress of optogenetics in exploring the pathogenesis and therapeutic targets of temporal lobe epilepsy, aiming to provide new ideas for temporal lobe epilepsy treatment.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.

Objective:To find out the distribution of water iodine in Jinzhong City, Shanxi Province, and provide scientific basis for scientifically delimiting the distribution range of different water iodine level areas.Methods:From March to August 2024, by using a cross-sectional survey method, the administrative villages (communities, abbreviated as administrative villages) were used as units in 11 counties (districts, cities, abbreviated as counties) of the city to verify the changes in the names and administrative divisions of counties, townships, and administrative villages based on the survey results of iodine content in drinking water in the city in 2017. Population data, water source information, and water supply project operation were investigated, and 10% sampling method was used to collect drinking water samples. Cerium sulfate catalytic spectrophotometry was used to test water iodine level.Results:A total of 2 402 centralized water supply projects in 2 181 administrative villages were investigated and all were operating normally. The median iodine concentration in the city's water was 2.43 μg/L, ranging from 0.15 to 556.45 μg/L. The number of villages and population covered by water iodine level of < 40, 40 - 100, and > 100 μg/L was 1 990 villages and 2 841 752, 153 villages and 372 085, 38 villages and 75 493, respectively.Conclusions:According to the classification of water iodine standards, Jinzhong City presents a coexistence of iodine deficiency, adequate iodine, and high iodine areas, with iodine deficiency areas still being the main focus. Therefore, it is necessary to continue implementing salt iodization measures. Areas with high iodine levels need to continue to promote the implementation of measures to improve water quality, reduce iodine levels, and supply non iodized salt. Efforts should be made to promote disease prevention knowledge among key areas and populations, guide the public to scientifically supplement iodine, and effectively control the hazards of high iodine.

Objective:To investigate the clinical and genetic variation characteristics of a child with autosomal dominant lateral temporal lobe epilepsy caused by de novo variation of the MICAL1 gene. Methods:Clinical data of the patient with autosomal dominant lateral temporal lobe epilepsy caused by MICAL1 gene variation diagnosed in Children′s Hospital of Soochow University in August 2019 were collected. The whole exome sequencing was performed on the core members of the family, and the characteristics of gene variations were analyzed. Results:The proband, a 10 years and 5 months old boy, was admitted to the hospital because of "intermittent convulsions for 7 years". The clinical manifestations included focal or generalized tonic-clonic seizures and hearing aura, with normal language and intellectual development. No abnormalities were found in the T 1 and fluid attenuated inversion recovery sequences of the cranial 3.0 T magnetic resonance imaging and 3D thin-slice magnetic resonance imaging.Long-range video electroencephalogram showed the distribution of spinous and slow spinous waves in the left frontal and temporal areas. The results of whole exome gene sequencing in the core family members showed heterozygous de novo missense variation in the MICAL1 gene of the proband (NM_022765): c.763G>T(exon6)(p.Val255Leu) that had not been reported. According to American College of Medical Genetics and Genomics and Association for Molecular Pathology guidelines (2015), the mutation was considered potentially pathogenic. The application of antiepileptic drugs was effective in controlling epileptic seizures. Conclusions:Auditory symptoms are main clinical manifestations for the child with autosomal dominant lateral temporal lobe epilepsy. Antiepileptic drugs can effectively control epileptic seizures of the child, and the MICAL1 gene c.763G>T (p.Val255Leu) mutation is the genetic cause of the proband.

Objective:To summarize the clinical characteristics of 5 children with developmental epileptic encephalopathy type 17 (DEE17) caused by GNAO1 gene variants confirmed by whole-exome sequencing and analyze the features of their genetic variants. Methods:A retrospective analysis was conducted on the clinical data of 5 children diagnosed with GNAO1-related DEE17 in the Department of Neurology, Children′s Hospital of Soochow University from January 2019 to October 2024. Their clinical features, genetic testing results, neuroimaging findings, electroencephalogram (EEG) results, and treatment regimens were summarized. Follow-up was performed via telephone or outpatient visits. Results:Among the 5 diagnosed children (3 males, 2 females), the age of onset ranged from 2 days to 2 years, and the age at diagnosis ranged from 2 days to 6 years. Four children presented with seizures in the neonatal or infantile period, manifesting as hypotonia, developmental delay, and seizure types including generalized tonic-clonic, myoclonic, and epileptic spasms. One child had a later onset at 2 years, presenting with language delay, intellectual disability, and involuntary movements, followed by seizures at 6 years, including focal and generalized tonic-clonic seizures. Genetic testing revealed de novo heterozygous missense variants in GNAO1 in all 5 cases: c.119G>C (p.G40A), c.808A>C (p.N270H), c.808A>G (p.N270D), c.118G>C (p.G40R), and c.17G>T (p.S6I). Among these variants, c.119G>C and c.17G>T were previously unreported pathogenic variants. Neuroimaging showed nonspecific changes in 3 children (widened frontal-temporal subarachnoid space, delayed myelination) and abnormal white matter signals in 2 cases. Long-term video-EEG revealed abnormal discharges and background slowing in all cases: multifocal discharges in 4 cases and focal epileptiform discharges (left mid-temporal) in 1 case. Clinical seizures were captured in 3 cases: 1 with a burst-suppression pattern and 2 with hypsarrhythmia. All patients received 3 or more antiseizure medications. Four cases (cases 1-4) responded well to topiramate combination therapy, with 2 cases (cases 1, 2) achieving complete seizure freedom and 2 cases (cases 3, 4) experiencing more than a 50% reduction in seizures. One child (case 3) achieved seizure control with an adjunctive ketogenic diet. The late-onset case (case 5) required a combination of levetiracetam, oxcarbazepine, and valproate for seizure management. Conclusions:GNAO1 variants can lead to DEE17 with diverse seizure types, often requiring multiple antiseizure medications, among which topiramate is effective. Early-onset cases typically present with seizures and developmental delay, while late-onset cases may exhibit language delay, intellectual disability, movement disorders, and refractory epilepsy. Genetic testing should be performed early for timely diagnosis.

Objective:To investigate the correlation between frailty and falls among older adult residents in communities in Xinjiang Uygur Autonomous Region.Methods:This study is a prospective research. In June 2024, the 1 047 older adults (aged 65 years and older) included in the "A longitudinal cohort study of aged population in Xinjiang" (ChiCTR2400093292) were followed up. The Fried frailty phenotype was used to assess the frailty status of the participants, and general information was collected, including whether the participants had experienced falls in the past 12 months. Multivariate logistic regression analysis was performed to identify the risk factors for falls among older adults in communities in Xinjiang Uygur Autonomous Region.Results:Among the 1 047 participants, the incidence of falls among older adults was 10.2% (107/1 047). There were significant differences in frailty status and age between case and control groups (both P < 0.05). Logistic regression analysis indicated that frailty and increasing age are risk factors for falls among older adults in communities in Xinjiang Uygur Autonomous Region. The more severe the frailty, the greater the risk of falls ( χ2 = 7.57, P < 0.006, OR = 2.509, 95% CI: 1.303-4.830). Similarly, the greater the age, the greater the risk of falls ( χ2=8.94, P = 0.003, OR = 1.030, 95% CI: 1.013-1.064). Conclusions:Falls among older adults in communities in Xinjiang Uygur Autonomous Region are closely associated with frailty. It is essential to improve the assessment and screening of fall risks in frail older adults and to develop effective and appropriate fall prevention measures for this high-risk population.

Objective:To establish a rapid method for determination of iodine in water by sodium persulfate oxidation inductively coupled plasma mass spectrometry (ICP-MS).Methods:A 100 μl of 30% sodium persulfate solution was added to 10 ml of water sample, followed by reaction at room temperature for 30 min. A 50 μg/L mixed solution containing indium and 8 other elements was used as the internal standard solution. The flow ratio of the internal standard solution to the test solution was 1∶7. The iodine in water was determined by ICP-MS. The linear range, detection limit, accuracy, precision, and anti-interference ability of the method were evaluated.Results:Iodine in water could be determined and had a good linear relationship within the range of 0 - 100 μg/L, with a correlation coefficient ( r) of ≥0.999 9. The detection limits of potassium iodate and potassium iodide were 0.07 and 0.08 μg/L, respectively, and the quantitation limits were 0.24 and 0.26 μg/L, respectively. The low, medium, and high concentration spiked recovery rates of six substrate water samples (source water, treated water, end-use water, packaged drinking water, packaged mineral water, and natural mineral water) ranged from 94.0% to 104.0%, with a relative standard deviations ( RSD) ranged from 0.5% to 2.8%. Interference test confirmed that 29 elements (at 1.00 mg/L) did not affect the determination of iodine at 6.00 μg/L. The determination results of the standard substance (GBW09114K) for iodine content in water were all within the standard range (56.0 - 68.0 μg/L), with an RSD of 0.6%. Conclusions:A method for rapid determination of iodine in water by the sodium persulfate oxidation ICP-MS method is successfully established. This method is easy to operate, has high sensitivity and good accuracy, and is suitable for batch analysis of iodine in drinking water and mineral water.
