Objective: To assess the effect of transarterial embolization (TAE) for adhesive capsulitis (AC) by evaluating clinical outcomes and changes in inflammation using magnetic resonance imaging (MRI). Materials and Methods: Patients who had undergone TAE between August 2020 and August 2023 for AC refractory to conservative treatments without any invasive procedures for more than 3 months, and had undergone baseline and 3-month post-AC follow-up contrast-enhanced MRI evaluations, were included. A suspension mixture of 500 mg imipenem/cilastatin in 10 mL of iodinated contrast agent was used for TAE. MRI results were analyzed to assess periarticular capsule/ligament inflammation. Clinical assessments included pain scores using the numeric rating scale (NRS) and functional scores using the quick disabilities of the arm, shoulder, and hand (Quick DASH) questionnaire. Results: Twenty-five patients (female:male, 14:11; age, 54.9 ± 7.1 years) were included. Significant reductions in average NRS pain scores as well as improvements in Quick DASH scores and range of motion, including anterior flexion and abduction, were observed at 1, 3, and 6 months after TAE (all P < 0.001). MRI analyses revealed that TAE significantly decreased the grades of axillary recess capsule enhancement, rotator interval (RI) capsule T2 signal intensity, and RI capsule enhancement (all P ≤ 0.004). Conclusion TAE may be an effective and safe therapeutic approach for AC refractory to conservative treatments, alleviating pain and supporting functional recovery. The observed MRI findings suggest that the effectiveness of TAE for AC may be attributed to the reduction of inflammation and the elimination of angiogenesis.

Objective:To analyze the relationship between microRNA-21(miR-21)expression and the risk of very early relapse post-induction chemotherapy in children with acute lymphoblastic leukemia(ALL).Methods:A total of 110 newly diagnosed children with ALL admitted to Huanggang Central Hospital from March 2020 to September 2022 were included.All patients received induction chemotherapy according to the CCLG-2008 protocol.The patients who achieved complete response(CR)after induction chemotherapy were followed up for 18 months,with very early relapse as the endpoint event.Then the patients were divided into a relapse group and a non-relapse group.Cox regression was used to analyze the influencing factors of very early relapse after induction chemotherapy in children with ALL.ROC curve and decision curve were used to evaluate the predictive value of peripheral blood miR-21 for very early relapse after induction chemotherapy in children with ALL.Restricted cubic splines were used to analyze the dose-response relationship between peripheral blood miR-21 and very early relapse after induction chemotherapy in children with ALL.Results:A total of 102 children with ALL achieved CR after induction chemotherapy,among whom 24 cases(23.53％)experienced very early relapse,with a median relapse time of 14 months.The proportions of patients with high-risk stratification at initial diagnosis,extramedullary infiltration,and minimal residual disease(MRD)positivity were significantly higher in the relapse group than those in the non-relapse group;The absolute lymphocyte count(ALC)in peripheral blood was significantly lower,while the expression levels of miR-21 and lactate dehydrogenase(LDH)were significantly higher in the relapse group compared with the non-relapse group(all P＜0.05).Cox regression analysis showed that very early relapse after induction chemotherapy in children with ALL was associated with medium risk and high risk at initial diagnosis,extramedullary infiltration,decreased ALC in peripheral blood,MRD positivity,as well as high expression levels of miR-21 and LDH(all P＜0.05).ROC curve analysis indicated that the area under the curve(AUC)of peripheral blood miR-21 for predicting very early relapse after induction chemotherapy in children with ALL was 0.800,with an optimal cutoff value of 4.830.Restricted cubic spline analysis revealed that there was a non-linear dose-response relationship between peripheral blood miR-21 and the risk of very early relapse after induction chemotherapy in children with ALL.When the expression level of peripheral blood miR-21 exceeded 4.830,the risk of very early relapse increased with the elevation of miR-21 expression.Decision curve analysis demonstrated that combining peripheral blood miR-21 with other risk factors enhanced the predictive performance for the risk of very early relapse after induction chemotherapy in children with ALL.Conclusion:Very early relapse after induction chemotherapy in children with ALL is associated with elevated expression of miR-21 in peripheral blood,and high expression of miR-21 may increase the risk of very early relapse.Detecting miR-21 before induction chemotherapy has predictive significance for very early relapse in children with ALL,and combining it with other risk factors can improve the predictive efficacy.

Alcohol abuse is a global public health problem.Excessive drinking not only damages digestive tract,cardiovascu-lar and endocrine systems,but also damages central nervous system(CNS).Recent studies have shown that alcohol interacts with neu-roimmune system to alter neuroimmune signaling and molecular expression,thereby leading to neuroinflammation and regulating a wide range of brain functions.Microglia is main cell of CNS involved in neuroimmune responses.Microglia is activated by alcohol and acts on neurons,leading to neuropsychiatric diseases,such as neuronal loss,abnormal synaptic connections,cognitive decline and motor dysfunction.Alcohol chronically stimulates digestive tract and also affects microglia along gut-brain axis.Neural properties of microglia and related immune factors and their important roles in neuroinflammation provide a new insight into neuroimmune mecha-nisms underlying alcohol-induced changes in brain function and behavior.This review discusses progress of role of microglia and their immune signaling in alcohol-induced neuroinflammation,and provides theoretical basis for further research on neurobiological mecha-nism and treatment of alcohol abuse.

Objective:This study aims to investigate sex-specific abnormalities?? in gray matter volume (GMV) in Children with autism spectrum disorder (ASD) and their associations with gene expression.Methods:T 1-weighted brain MRI data were collected at the MRI Center of the University of Electronic Science and Technology of China between 2022 and 2023 from 100 children with ASD and 90 typically developing (TD) children. Voxel-based morphometry (VBM) was used to explore GMV differences between ASD boys and TD boys, and between ASD girls and TD girls. Partial least squares regression (PLSR) was performed based on the Allen Human Brain Atlas to identify genes associated with GMV alterations, followed by enrichment analyses. Cell-type-specific expression analyses were used to examine associations across developmental stages and brain structures. Protein-protein interaction (PPI) networks were constructed to identify hub proteins. Results:Compared to TD boys, ASD boys showed increased GMV in the right superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, temporal pole, parahippocampal gyrus, fusiform gyrus, cuneus, and precuneus, as well as in the bilateral orbital part of the superior frontal gyrus and the gyrus rectus. Decreased GMV was observed in the cerebellar vermis and bilateral cerebellar hemispheres. A total of 635 genes were associated with these GMV alterations, enriched in pathways related to DNA-templated transcription, RNA metabolism and biogenesis, and ion binding. Developmental analysis indicated strong associations with the cerebellum during early, middle-to-late childhood, and adolescence, and with the cerebral cortex in early adulthood. Protein-protein interaction (PPI) network analysis highlighted NOB1, GNL3L, ESF1, TFB2M, and WDR75 as specific hub proteins. Compared to TD girls, ASD girls exhibited increased GMV in the right middle and inferior temporal gyri, temporal pole, and fusiform gyrus, and decreased GMV in the cerebellar vermis and bilateral cerebellar hemispheres. A total of 765 genes were associated, enriched in pathways related to ion channel activity, signal transduction, and regulation of membrane potential. These genes showed strong associations with the amygdala during mid-to-late fetal development, middle-to-late childhood, adolescence, and early adulthood; with the cerebellum during late infancy, early childhood, and early adulthood; with the cerebral cortex during the mid-to-late fetal development, early neonatal period, and adolescence; with the hippocampus during middle-to-late childhood and adolescence; with the striatum during adolescence and early adulthood; and with the thalamus during early-to-mid fetal development, early neonatal period, and early adulthood. PPI network analysis identified ANK3, ANK1, SCN4B, NFKB1, and PXN as specific hub proteins. Conclusion:Both ASD boys and ASD girls exhibit GMV abnormalities compared with TD controls. The specific genes associated with GMV alterations are enriched in distinct biological pathways in boys and girls. Cell-type-specific expression analyses further revealed sex-dependent differences in developmental timing and brain structural correlations, and distinct PPI networks were constructed for each group.

Objective:To improve the diagnosis and treatment of autoimmune hepatitis (AIH) in children by analyzing their clinical characteristics and outcomes.Methods:Case summary.The general data, clinical manifestations, laboratory parameters, liver pathology, treatment and outcomes of 6 AIH children diagnosed at Xi′an Children′s Hospital from January 2019 to March 2024 were retrospectively analyzed.Results:All the 6 patients were diagnosed with AIH-1, and 5 of them were female, accounting for 83.3%.The median age of onset was 6.2 years old.Three cases (50.0%) had insidious onset.Elevated hepatic aminotransferase levels were detected incidentally in 2 cases (33.3%).One case (16.7%) presented symptoms resembling those of viral hepatitis.Two cases (33.3%) were accompanied by extrahepatic autoimmune diseases.All the children tested positive for anti-nuclear antibodies with a titer ≥1∶80 or 1∶100.Four cases (66.7%), 3 cases (50.0%), and 1 case (16.7%) tested positive for anti-smooth muscle antibodies, anti-perinuclear neutrophil cytoplasm antibodies and anti-soluble liver antigen, respectively.Liver pathology showed infiltration of lymphocytes-plasma cells and moderate or severe interfacial inflammation in all the 6 cases.Two cases (33.3%) had rosettes.All the patients were given oral corticosteroids combined with Azathioprine or Mycophenolate mofetil.The patients were followed up for 24.8 (12.0-52.0) months, during which 3 cases (50.0%) had partial remission and 3 cases (50.0%) achieved complete remission.Four cases (66.7%) showed transaminase fluctuations during corticosteroid reduction or cessation.Conclusions:Autoantibodies and liver pathology are important evidence for diagnosing AIH in children.Immunosuppressants have a high remission rate in the treatment of this disease, but transaminase fluctuations are prone to occur during corticosteroid reduction or cessation.

Objective:To explore the factors influencing social avoidance in patients with dental arch deficiency.Methods:A purposive sampling method was used to select patients with dental arch deficiency who visited the Nanjing Medical University Affiliated Stomatological Hospital from July 2023 to February 2024. Data were collected through semi-structured interviews, and the Colaizzi 7-step method was used to analyze the interview data.Results:A total of 14 patients with dental arch deficiency were interviewed, aged 36 to 72 years; eight were male, and six were female. Three main themes and eight sub-themes were identified: body image dysregulation (speech impairment, chewing dysfunction, muscle imbalance, appearance pressure, and conflict with social identity) ; loss of self-identity (over-awareness of self, internalized social stigma, and catastrophic interpretation) ; lack of social support network (insufficient medical team support and lack of support from core social circles) .Conclusions:Healthcare providers can develop intervention measures based on the factors influencing social avoidance in patients with dental arch deficiency to help patients restore social functionality.

Alzheimer’s disease (AD) is a prevalent neurodegenerative condition characterized by progressive cognitive decline and memory loss. As the incidence of AD continues to rise annually, researchers have shown keen interest in the active components found in natural plants and their neuroprotective effects against AD. Quercetin, a flavonol widely present in fruits and vegetables, has multiple biological effects including anticancer, anti-inflammatory, and antioxidant. Oxidative stress plays a central role in the pathogenesis of AD, and the antioxidant properties of quercetin are essential for its neuroprotective function. Quercetin can modulate multiple signaling pathways related to AD, such as Nrf2-ARE, JNK, p38 MAPK, PON2, PI3K/Akt, and PKC, all of which are closely related to oxidative stress. Furthermore, quercetin is capable of inhibiting the aggregation of β‑amyloid protein (Aβ) and the phosphorylation of tau protein, as well as the activity of β‑secretase 1 and acetylcholinesterase, thus slowing down the progression of the disease.The review also provides insights into the pharmacokinetic properties of quercetin, including its absorption, metabolism, and excretion, as well as its bioavailability challenges and clinical applications. To improve the bioavailability and enhance the targeting of quercetin, the potential of quercetin nanomedicine delivery systems in the treatment of AD is also discussed. In summary, the multifaceted mechanisms of quercetin against AD provide a new perspective for drug development. However, translating these findings into clinical practice requires overcoming current limitations and ongoing research. In this way, its therapeutic potential in the treatment of AD can be fully utilized.
