OBJECTIVE:
To explore the serological and molecular genetic characteristics of a family with subtype B(A)06.
METHODS:
A neonatal hyperbilirubinemia patient who was treated at Henan Children's Hospital on June 15, 2023 due to "yellowing of the skin and gradual aggravation", and was found to have inconsistent ABO forward and reverse typing through blood type testing, was selected as the research subject. Six milliliters of peripheral blood were collected from the newborn and her family members (grandfather, grandmother, father, mother and aunt) respectively. ABO blood group identification was performed by the blood group serological method. Human genomic DNA was extracted using the nucleic acid extraction or purification reagent BT-01. ABO gene exons 2 to 7 were amplified by PCR. The PCR-specific products that were successfully amplified were sequenced by Sanger method. Taking ABO*A1.01 as the reference sequence, the ABO gene sequences of the newborn and her family members were analyzed to determine the ABO genotype. The procedures followed in this study were approved by the Ethics Committee of Henan Children's Hospital (Ethics No.: 2022-K-L036).
RESULTS:
The serological results of ABO blood group showed that the newborn, her grandfather, father and aunt were all incompatible with the forward and reverse typing. The blood group phenotype of the newborn was AwB or B(A), the blood group phenotype of the grandfather was A2B or B(A), the blood group phenotype of the father and aunt were A2B, and the blood group phenotype of the grandmother and mother were both O. The screening test results of hemolytic disease of the newborn showed that the free test detected IgG anti-A1 antibody, while the elution test, direct antiglobulin test and antibody screening results were all negative. The Sanger sequencing results showed that the newborn had variations of c.261delG, c.297A>G, c.526C>G, c.657C>T, c.703G>A, c.796C>A and c.930G>A. Her grandfather had variations of c.297A>G, C.526C>G, c.657C>T, c.703G>A, c.796C>A, c.803G>C and c.930G>A. Her grandmother had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.646T>A, c.681G>A, c.771C>T and c.829G>A. Her father and aunt had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.526C>G, c.646T>A, c.657C>T, c.681G>A, c.703G>A, c.771C>T, c.796C>A, c.829G>A and c.930G>A. Her mother had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.646T>A, c.681G>A, c.771C>T, and c.829G>A.The genotype of the newborn was ABO*BA.06/ABO*O.01.01, her grandfather was ABO*BA.06/ABO*B.01, her grandmother was ABO*O.01.02/ABO*O.01.02, her father and aunt were ABO*BA.06/ABO*O.01.02, and her mother was ABO*O.01.01/ABO*O.01.02. The ABO*BA.06 allele of the newborn, grandfather, father and aunt was caused by the c.803C>G variation in exon 7 based on the ABO*B.01 allele. The ABO*BA.06 allele can be stably inherited in this family.
CONCLUSION
The blood type of neonatal patients with B(A)06 subtype can be accurately determined by gene sequencing technology. If the forward typing is ≤ 3+ agglutination intensity in newborn ABO blood group identification, the reason should be carefully analyzed, and the molecular biology technology and family gene sequencing results should be used to jointly determine if necessary.

Objective To explore function-structure covariant patterns in Alzheimer's disease(AD)and mild cognitive impairment(MCI),and to investigate their associations with cognitive function and activities of daily living.Methods three-way parallel group independent component analysis(three-way pGICA),was used to identify the covariant patterns of resting-state functional MRI temporal data,gray matter density maps,and fractional anisotropy(FA)maps,and the differences between different groups were compared.Furthermore,the associations of covariant patterns with the Montreal Cognitive Assessment-Basic(MoCA_B)Scale scores and Activities of Daily Living Scale scores were analyzed.Results The function-structure covariant patterns in AD and MCI were characterized by the enhanced negative functional connectivity between the left posterior salience network and the right default mode network,the decreased gray matter density in the bilateral dorsolateral prefrontal cortex,and the reduced FA values in the left superior corona radiata(correlations:P<0.001,FDR corrected).Compared with HC group,AD group showed significant abnormalities in all identified covariant patterns(P<0.01,FDR corrected),but MCI group only exhibited a significant decrease in gray matter density in the bilateral dorsolateral prefrontal cortex(P<0.05,FDR corrected).Additionally,AD group had significantly lower FA value in the left superior corona radiata than MCI group(P<0.05,FDR corrected).The loadings reflecting the degree of covariation were significantly correlated with the Activities of Daily Living Scale scores(P<0.05,FDR corrected)but not with MoCA_B Scale scores.Conclusion The function-structure covariant patterns in AD and MCI are consistent with the declines in activities of daily living.The multimodal fusion analysis(three-way pGICA)provides a novel approach to understand the brain damage mechanisms underlying the covariant evolution of MCI and AD.

Neuronal intranuclear inclusion disease(NIID)is a rare hereditary neurodegenerative disorder that can affect multiple systems. However,it is uncommon for urinary dysfunction to be the initial symptom. This article reports five cases. The five patients began to experience voiding dysfunction such as frequent urination,weak urination,and incomplete urination at the mean ages of 55.4(47 - 65)years old. Four months to twelve years after urinary onset,neurological symptoms such as headache,memory decline,transient loss of consciousness,and unsteady gait began to appear. Four of the five cases had a family history. Brain MRI revealed the “ribbon sign” or “crest sign” in all cases. Skin biopsy revealed eosinophilic inclusions in the cell nuclei,and NOTCH2NLC gene testing identified abnormal GGC mutations. Three of the five patients underwent cystostomy due to secondary hydronephrosis,while the other two received no special treatment. After a follow-up of 18 to 35 months since diagnosis,the patients who underwent cystostomy had normal renal function. Neurological symptoms in all five patients worsened to varying degrees.

AIM:This study explores whether curcumin(Cur)promotes mitophagy to attenuate nonalcoholic steatohepatitis(NASH)in mice,as well as the possible molecular mechanisms involved.METHODS:A high-fat and high-cholesterol diet was used to replicate the NASH mouse model.Thirty-two male C57BL/6J mice were randomly divided into normal control(NC)group,high-fat and high-cholesterol model(M)group,M+low-dose Cur(Cur-L)group,and M+high-dose Cur(Cur-H)group,with 8 mice in each group.The weight of 8 mice in each group was recorded weekly.After feeding for 18 weeks,the serum and liver of mice were collected.Serum levels of total cholesterol(TC),triglyceride(TG),low-density lipoprotein(LDL-C),alanine aminotransferase(ALT),aspartate aminotransferase(AST),and tumor necrosis factors-α(TNF-α)were measured.Liver index was calculated,and steatosis,inflammation,and fibrosis of the liver were observed by HE and Masson staining.Western blot analysis was performed to detect the protein expression of mi-tophagy-related protein,TNF-α and α-SMA in the liver.(2)HepG2 cells were treated with oleic acid and cholesterol to replicate the hepatocyte injury model,which was divided into NC group,Cur group,M group,and M+Cur group.Small interfering RNA for PTEN-induced kinase 1(PINK1)knockdown was used to explore the relationship between PINK1-me-diated mitophagy and NASH.Compound C(CC)was used to inhibit AMP-activated protein kinase(AMPK)to explore the effect of the AMPK/silent information regulator 1(Sirt1)pathway on mitophagy.The lipid droplets of HepG2 cells were ob-served by oil red O staining,and the levels of TC,TG,LDL-C,ALT,and AST in cell suspension were detected.RE-SULTS:(1)Compared with M group,treatment with Cur significantly reduced the body weight,liver coefficient,and se-rum levels of TC,TG,LDL-C,ALT,AST,and TNF-α in NASH mice,while the steatosis and fibrosis in the liver were improved(P<0.05).(2)Different concentrations of Cur could increase or decrease the expression of mitophagy-related proteins in HepG2 cells in a concentration gradient.Compared with the M group,Cur reduced lipid droplets and de-creased TC,TG,LDL-C,ALT,and AST levels(P<0.05).(3)Compared with the NC group,the expression levels of mi-tophagy-related proteins in the liver of mice in the M group decreased,and the expression levels of TNF-α and α-SMA pro-teins increased.Different concentrations of Cur intervention promoted the increase of mitophagy-related proteins and the decrease of TNF-α and α-SMA proteins(P<0.05).(4)After Cur intervention,the expression levels of mitophagy-related proteins increased and the expression levels of in TNF-α and α-SMA levels decreased in HepG2 cells induced by oleic acid and cholesterol(P<0.05).(5)Compared with M group,oleic-acidand cholesterol-induced mitophagy function in HepG2 cells was decreased after PINK1 knockdown(P<0.05).After CC inhibited AMPK,Cur increased the expression of p-AMPK(P<0.01),Sirt1(P<0.01),peroxisome proliferator-activated receptor γ coactivator-1α(P>0.05),PINK1(P<0.01)and parkin(P<0.01)proteins to some extent.CONCLUSION:Treatment with Cur attenuates liver injury in NASH mice and reduces lipid accumulation in HepG2 cells induced by oleic acid and cholesterol,and the mechanism may be related to promotion of mitophagy,which may involve the AMPK/Sirt1 signaling pathway.

Background and Aims:Gamma-aminobutyric acid(GABA),the principal inhibitory neurotransmitter in the central nervous system,has been increasingly recognized in recent years as being closely associated with various liver-related diseases,such as hepatic encephalopathy,liver cirrhosis,and hepatocellular carcinoma.Abnormal GABA expression is strongly linked to pathological processes including cognitive impairment and neuroinflammation.Although numerous studies have investigated the mechanistic roles of GABA in neurological complications of liver disease,a systematic overview of the field's research trends,collaborative networks,and emerging hotspots remains lacking.This study employs bibliometric methods to comprehensively map the evolution and frontier topics in GABA and liver-related disease research from 2005 to 2024,aiming to inform future research planning and resource allocation in this area.Methods:English-language publications from 2005 to 2024 related to GABA and liver-related diseases were retrieved from the Web of Science Core Collection.Eligible articles were analyzed using VOSviewer,CiteSpace,and the R package"bibliometrix"to visualize and evaluate contributions by countries/regions,institutions,authors,and journals.Additional analyses included keyword clustering,co-citation analysis,and thematic evolution of research topics.Results:A total of 237 articles were included,contributed by 1 340 authors across 456 institutions in 47 countries,and published in 168 journals.The United States and China are leading contributors in this field.Although countries such as the United Kingdom and Italy had fewer publications,they demonstrated higher average citation counts,indicating strong research quality.Notably,Spain's Centro Investigación Principe Felipe and the research team led by Felipo Vicente exhibited high academic influence.Neurochemistry International and Hepatology were identified as core journals,with Hepatology having the highest impact factor(12.9).Keyword clustering revealed major research focuses including the regulatory role of GABA in the neural mechanisms of hepatic encephalopathy,the impact of liver-related metabolic disorders on neurotransmitter balance,the development and evaluation of GABA receptor-targeted therapeutics,and the function of the GABAergic system in the pathogenesis of hepatocellular carcinoma.As research deepens,the frequency of emerging keywords has diversified,with recent emphasis on terms such as"quality of life,""gene expression,"and"fatty liver disease,"reflecting a shift from fundamental mechanisms to clinical translation and interdisciplinary integration.Conclusion:The relationship between GABA and liver diseases has become a focal point of interdisciplinary research.Investigations have expanded from pathological mechanisms to therapeutic applications,with growing interest in GABA's roles in hepatic encephalopathy,metabolic dysregulation,and tumor progression.Future studies should explore the specific functions of GABA receptor subtypes,promote the development of precision-targeted therapies,and investigate novel mechanisms such as the gut microbiota-GABA metabolism-brain-liver axis to broaden the clinical and translational potential of GABA in neurological,metabolic,and oncological contexts.

Objective:To evaluate the effect of esketamine on caspase-11-mediated non-canonical pathway pyroptosis in sepsis-induced acute lung injury in rats.Methods:Eighteen SPF healthy Sprague-Dawley rats, aged 8-12 weeks, weighing 280-320 g, were divided into 3 groups ( n=6 each) using a random number table method: sham operation group (Sham group), cecal ligation and puncture (CLP) group and CLP+ esketamine group (CLP+ ES group). Sepsis was induced by CLP in anesthetized animals. Esketamine 10 mg/kg was injected via the tail vein immediately after development of the model, and the equal volume of normal saline was injected via the tail vein in the other two groups. At 24 h after development of the model, the rats were sacrificed under anesthesia, and the lung tissues and blood samples were taken. The wet to dry lung weight ratio (W/D ratio) was calculated, and the pathological changes were observed and the lung injury was scored. The expression of caspase-11, gasdermin D-N (GSDMD-N), phosphorylated phosphatidylinositol 3-kinase (p-PI3K) and phosphorylated protein kinase B (p-AKT) was detected by Western blot. The expression of caspase-11 and GSDMD-N mRNA was detected by quantitative real-time polymerase chain reaction. The serum concentration of interleukin-1β (IL-1β) was determined by enzyme-linked immunosorbent assay. Results:Compared with Sham group, the lung injury score and W/D ratio were significantly increased, the expression of caspase-11 and GSDMD-N protein and mRNA was up-regulated, the expression of p-PI3K and p-AKT was down-regulated, and the concentration of IL-1β was increased in CLP group ( P<0.05). Compared with CLP group, the lung injury score and W/D ratio were significantly decreased, the expression of caspase-11 and GSDMD-N protein and mRNA was down-regulated, the expression of p-PI3K and p-AKT was up-regulated, and the concentration of IL-1β was decreased in CLP+ ES group ( P<0.05). Conclusions:The mechanism by which esketamine alleviates sepsis-induced acute lung injury may be related to the inhibition of caspase-11-mediated non-canonical pathway pyroptosis in rats.

Objective:To investigate the differential effects of proton FLASH irradiation and conventional dose rate (CONV) irradiation on human normal liver cells WRL68 and human hepatocellular carcinoma cells HepG2.Methods:Using a 100 MeV high-current proton cyclotron accelerator, WRL68 and HepG2 cells were subjected to CONV (0.8 Gy/min) and FLASH (40 Gy/s) irradiation with 4 Gy protons. After irradiation, changes in cell proliferation, apoptosis, and cell cycle arrest were detected at different time points. Additionally, transcriptome sequencing was employed to analyze alterations in the gene expression profiles of the two cell lines.Results:For WRL68 cells, compared with CONV irradiation, proton FLASH irradiation enhanced cell proliferative activity ( t=10.18-16.67, P<0.05), reduced the apoptotic rate ( t=3.21-8.30, P<0.05), and decreased the proportion of cells arrested in the G 2 phase at the same time points ( t=34.08-65.16, P<0.05). In contrast, for HepG2 cells, proton FLASH irradiation significantly inhibited cell proliferation ( t=2.57-9.39, P<0.05), increased the apoptotic rate ( t=3.25-66.70, P<0.05), and similarly induced cell cycle arrest predominantly in the G 2 phase ( t=10.87-27.47, P<0.05). Transcriptome sequencing identified 906 differentially expressed genes (DEGs) between the FLASH group and the CONV group in WRL68 cells, and 1 243 DEGs were detected in HepG2 cells. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of these DEGs suggested that cellular adhesion and oxygen effect may serve as crucial microscopic mechanisms underlying FLASH radiotherapy. Conclusions:Under proton FLASH irradiation, the radiation-induced damage to human normal liver cells was significantly alleviated, whereas the damage to hepatocellular carcinoma cells was aggravated. The identified DEGs are involved in multiple radiobiological functional pathways.
