BACKGROUND:Hydroxy safflower yellow A has anti-ischemia,anti-oxidation,anti-thrombotic and anti-inflammatory effects.Whether it affects neuronal pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation is still unclear. OBJECTIVE:To investigate the protective effect of hydroxy safflower yellow A on neuronal pyroptosis and its mechanism. METHODS:HT22 cells in logarithmic growth phase were randomly divided into five groups:normal group,model group,hydroxy safflower yellow A group,colivelin group,and colivelin+hydroxy safflower yellow A group.HT22 cells were treated with glucose-oxygen deprivation/reglucose-reoxygenation to establish neuronal pyroptosis model,and then treated with STAT3 agonist Colivelin and hydroxy safflower yellow A.JC-1 probe was employed to assess changes in mitochondrial membrane potential.Reactive oxygen species kit was used to determine the content of reactive oxygen species in cells.GSDMD/TUNEL staining was conducted to observe cell pyroptosis.Immunofluorescence analysis was performed to detect STAT3 and GSDMD protein expression.RT-PCR was utilized for assessing mRNA expression levels of STAT3,NLRP3,and Caspase-1.Western blot assay was utilized to measure the protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β. RESULTS AND CONCLUSION:(1)Compared with the normal group,the number of pyroptotic cells increased in HT22 cells in the model group along with a significant increase in protein expression levels of p-STAT3,NLRP3,Cleaved-caspase-1,GSDMD,and interleukin-1β.Compared with the model group,the number of pyroptotic cells reduced,and the expression of pyroptosis-related proteins significantly decreased in the hydroxy safflower yellow A group.(2)In comparison with the model group,pyroptosis worsened in the colivelin group where mitochondrial membrane potential decreased along with elevated reactive oxygen species content and increased mRNA expression levels of STAT3,NLRP3,and Caspase-1,as well as increased protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β.Compared with the Colivelin group,above indexes were improved in the colivelin+hydroxy safflower yellow A group.These results suggest that hydroxy safflower yellow A plays a neuroprotective role through STAT3 signaling pathway to inhibit HT22 pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation treatment.

Objective:
: Baculovirus inhibitory of apoptosis repeat-containing 5 (BIRC5) is critically implicated in various types of tumors. However, the specific mechanisms by which it operates in glioma are yet to be fully understood.
Methods:
: The data sourced from The Cancer Genome Atlas and Gene Expression Omnibus were merged and analyzed using the R software to investigate the relationship between BIRC5 expression and prognosis and diagnosis outcomes. This exploration was conducted utilizing various biological information repositories. The correlation between BIRC5 and immunity was obtained based on TIMER and TISIDB databases.
Results:
: Gliomas displayed a markedly elevated level of BIRC5 expression compared to adjacent tissues. Patients with glioma who exhibit elevated levels of BIRC5 experience poorer prognoses and shorter survival times. Subgroup classification further revealed that heightened expression of BIRC5 led to diminished overall survival. Analysis of logistic regression and COX indicated that expression of BIRC5 serves as a risk factor in glioma development. Functional enrichment pathways showed that the 72 hub genes related to BIRC5 were mainly closely related to nuclear division, spindle, tubulin binding, and cell cycle in glioma patients. BBIRC5 methylation suggested that BIRC5 might influence the immune response regulation and the tumor microenvironment within gliomas. BIRC5 is associated with many chemicals. Additionally, studies conducted using cell experiments and pathological sections have consistently shown that BIRC5 expression is higher in tumor cells compared to normal cells and tissues.
Conclusion
: BIRC5 holds promise as a valuable tool in the diagnosis, prognosis, and management of gliomas.

In recent years, with the clinical application of minimally invasive surgical techniques and comprehensive preoperative treatment, the survival rate of locally advanced esophageal cancer has significantly improved. However, the treatment of metastatic esophagogastric cancer still relies mainly on systemic therapy, and immunotherapy combined with chemotherapy has become a first-line treatment option, prolonging the survival of patients with metastatic esophageal cancer. Oligometastatic esophageal cancer is expected to bring survival benefits through systemic therapy combined with local treatment. The 2024 European clinical practice guidelines for oligometastatic esophagogastric cancer have been officially released, which standardize the definition, diagnosis, and treatment of oligometastatic esophageal cancer for further prospective studies. The authors interpret this guideline, especially by reviewing the clinical evidence of oligometastatic esophageal squamous cell carcinoma, to provide reference for the diagnosis and treatment of oligometastatic esophageal cancer in China.

With the increasing prevalence of overweight and obesity among children and adolescents in China, pediatric metabolic syndrome has emerged as a significant public health challenge. The Developmental Origins of Health and Disease (DOHaD) theory underscores the critical influence of early environmental factors on lifelong metabolic health. Consequently, maternal nutritional status and physical activity during pregnancy have become key modifiable factors that have attracted considerable attention in recent years. Research indicates exposure to a maternal high-fat diet (HFD) during pregnancy has long-term effects on offspring health, which may be transmitted through placental transit disorder, inflammation, and oxidative stress. Similarly, a high-protein diet (HPD) during pregnancy exhibits a dose- and time-dependent biphasic effect: excessive intake may lead to fetal growth restriction and an increased risk of preterm birth, whereas moderate supplementation may instead reduce the susceptibility of offspring to obesity. Interestingly, caloric restriction (CR) during pregnancy presents a double-edged sword: while it may impair the development of metabolic organs in offspring, moderate CR in metabolically compromised mothers can ameliorate maternal metabolic dysfunction and reprogram oocyte DNA methylation, significantly lowering the risk of metabolic disorders in offspring. Notably, metabolic abnormalities induced by a low-protein diet (LPD) during pregnancy demonstrate lifecycle-accumulative effects and transgenerational inheritance, with offspring exhibiting obesity phenotypes during weaning, insulin resistance in adulthood, and hepatic decompensation in old age, mediated through oocyte epigenetic reprogramming. Additionally, maintaining an optimal micronutrient balance is crucial for the metabolic homeostasis of offspring, as both deficiency and excess can lead to detrimental outcomes. Maternal exercise has been established as a safe and effective non-pharmacological intervention that confers multigenerational metabolic benefits through diverse biological pathways. Maternal metabolic dysregulation represents a critical determinant of offspring metabolic disorders. Regular exercise during gestation exerts protective effects by attenuating maternal systemic inflammation and reducing the incidence of pregnancy-related complications, thereby effectively mitigating fetal overgrowth and metabolic dysfunction. This dual benefit for both mother and offspring underscores the pivotal role of gestational physical activity in promoting long-term metabolic health. The placenta, serving as the exclusive interface for maternal-fetal communication, mediates exercise-induced metabolic programming through enhanced secretion of key regulatory factors (including SOD3, Apelin, ADPN, and Irisin) and promotes the development of vascular networks, collectively optimizing nutrient transport efficiency. The intrauterine period represents a crucial window for epigenetic reprogramming, during which maternal exercise modulates DNA methylation patterns of critical metabolic genes (e.g., Ppargc-1α, Prdm16, Klf4, and Slc23a2) in offspring, thereby enhancing their capacity to resist metabolic disorders. Notably, the regulatory effects of maternal exercise extend beyond the gestational period. Postnatally, exercise-induced modifications in the bioactive components of breast milk and gut microbiota composition contribute to the sustained maintenance of metabolic homeostasis in offspring, establishing a continuum of metabolic protection from prenatal to postnatal stages. This review explores the potential of maternal combined nutrition-exercise interventions, suggesting that such strategies may synergistically enhance transgenerational health benefits through interactions within the metabolic-epigenetic network, thereby outperforming single interventions. Additionally, it examines current research limitations, including controversies surrounding transgenerational mechanisms, sex-specific responses, and undefined dynamic thresholds, while providing directions for future investigations. These findings pave the way for a theoretical foundation for early-life health interventions, potentially offering a more effective strategy for combatting intergenerational metabolic disorders.

Ischemia-reperfusion injury (IRI) can lead to organ dysfunction and tissue necrosis in the liver, kidney, myocardium and spinal cord, and there is currently a lack of effective treatment options. Human umbilical cord mesenchymal stem cell (HUC-MSC) and their derivatives have anti-inflammatory, anti-apoptotic, reactive oxygen species scavenging, mitochondrial and endothelial function improvement properties, and are ideal gene therapy carrier cells, providing new possibilities for the treatment of IRI in different organs. This article reviews the concept and mechanisms of IRI, the biological characteristics of HUC-MSC and their derivatives and their comparison with mesenchymal stem cells from other sources, and the mechanisms of HUC-MSC in treating IRI in different organs. It also summarizes and analyzes the advantages and disadvantages of HUC-MSC in protecting different organs from IRI, and prospects future research directions to explore more valuable research paths.

Objective:
To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD.
Methods:
A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD.
Results:
The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20;-2.04,-3.25;2.35,3.21, P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05).
Conclusions
School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

Objective To explore the association between different levels of fluoride exposure and dyslipidemia in elderly people, and to analyze the influencing factors and their interactions. Methods A total of 1 143 elderly people over 60 years old were randomly selected from historical high water fluorosis areas and control areas in Tianjin. Logistic regression model and classification tree model were used to analyze the influencing factors of dyslipidemia, and to analyze the interaction between high fluoride exposure and relevant influencing factors on dyslipidemia. Results The prevalence of elevated low density lipoprotein cholesterol (LDL-C) was 5.69% (65/1 143). There was a significant difference in the prevalence of high LDL-C in different fluoride-exposed areas (2 = 0.092,P = 0.762). Multivariate logistic analysis showed that high fluoride exposure (OR=2.306,95%CI:1.185-4.491) and abdominal obesity (OR=2.274,95%CI:1.299-3.978) were risk factors for high LDL-C, while type B personality (OR=0.529,95%CI:0.308-0.908) was a protective factor for high LDL-C. The results of classification tree model showed that abdominal obesity contributed the most to the prevalence of high LDL-C in the elderly, followed by high fluoride exposure and hyperglycemia. There was a significant multiplicative interaction between high fluoride exposure and abdominal obesity on dyslipidemia (OR=5.191,95%CI:1.609-16.745,P=0.006). Conclusion High fluoride exposure may increase the risk of high LDL-C, and there is a multiplicative interaction between high fluoride exposure and abdominal obesity on dyslipidemia.

Objective Idiopathic rolandic epilepsy syndrome (IRES) is the most common epilepsy syndrome in childhood, and its lesion site remains undetermined. This article aims to investigate the source of epileptiform discharges in IRES using magnetoencephalography (MEG).Methods A total of 70 patients with IRES were enrolled in this prospective MEG-based study, among whom there were 53 children with benign epilepsy of childhood with centrotemporal spikes (BECTS), 12 children with atypical benign partial epilepsy (ABPE), 3 children with Landau-Kleffner syndrome (LKS), and 2 children with epileptic encephalopathy with continuous spike-and-waves during slow-wave sleep (CSWS). Epileptiform discharges were collected independently from each patient 10 times, and an MEG source analysis was performed. Standardized low-resolution brain electromagnetic tomography was used to perform source localization of the distributed source model. The spike source density was quantified into amplitude, and source location was determined according to the Desikan-Killiany atlas. The association between the distribution of spike source in brain and clinical manifestations was analyzed.Results In IRES, there were significant differences in the source locations of epilepsy discharge between BECTS, ABPE, LKS, and CSWS. The current source density of CSWS was stronger in the frontal lobe, the temporal lobe, and the anterior cingulate gyrus, while that of ABPE was stronger in the frontal lobe, and that of BECTS and LKS were stronger in the temporal lobe. The more severe phenotype of epilepsy, such as generalized tonic-clonic seizure, was associated with a stronger current source density in the brain, which was consistent with electroencephalography manifestations.Conclusion This study identifies different sources of epileptiform discharges in IRES. The density distribution of these spike sources may help to explain the discharge, cognitive, and neuropsychological characteristics in different subtypes of IRES.

Objective:
To analyze the trends, gender, and age differences in the incidence of lip and oral cavity cancer in Chinese population from 1990 to 2021 and predict future incidence trends, providing a scientific basis for disease prevention and public health policy.
Methods:
Incidence data of lip and oral cavity cancer in Chinese population from the Global Burden of Disease (GBD) database from 1990 to 2021 were analyzed. The Joinpoint regression model was used to assess temporal trends, the age-period-cohort model was used to evaluate the independent effects of age, period, and cohort, and the Bayesian age-period-cohort model (BAPC) model was used to predict incidence trends from 2022 to 2044.
Results:
From 1990 to 2021, the age-standardized incidence rate of lip and oral cavity cancer in Chinese population increased from 2.39/100 000 to 3.76/100 000, and the crude incidence rate rose from 1.71/100 000 to 4.85/100 000. The incidence rate in males was higher and increased more rapidly than in females. Higher incidence rates were prevalent among older populations, a rapid increase in incidence rates occurred during 2003 to 2012, and earlier birth cohorts showed overall higher risks. BAPC predictions indicated a continued rise in incidence from 2022 to 2044. During this period, male incidence stabilized while female incidence increased at a relatively faster rate.
Conclusion
The incidence of lip and oral cavity cancer in Chinese population has revealed a continuous upward trend, particularly among males and older populations. Future prevention strategies should focus on these high-risk populations.

Emergence agitation (EA) is a common complication after general anesthesia, especially in children and adolescents. Remifentanil, as a short-acting μ-receptor agonist, has become an important drug for the prevention and treatment of EA due to its rapid recovery and low risk of respiratory depression. This article reviews the mechanism of action and clinical research progress of remifentanil in the prevention and treatment of EA. Its mechanism of action involves the inhibition of pain signals mediated by traditional μ-receptor activation and potential new mechanism based on neural-endocrine-immune network, including regulation of microglial inflammatory pathways, and the modulation of cytokines and chemokines,etc. Clinical studies have shown that remifentanil can significantly shorten the recovery time, reduce the incidence of EA, and further optimize the analgesic effect and recovery quality by combining with other drugs (such as local anesthetics, sedatives, and opioid drugs). Future research should further explore the mechanism of action of remifentanil, optimize clinical treatment strategies, and conduct large- scale clinical trials to standardize the drug use plan, while paying attention to its long-term effects and the development of multimodal treatment plans to promote the further development of EA prevention and treatment plans.
