Objective: To analyze a case of hemolytic disease of the fetus and newborn (HDFN) caused by anti-Jk3 antibody, which was induced in a rare Jk (a-b-) blood type resulting from a gene mutation in the Kidd blood group system, so as to provide a reference for the diagnosis and treatment of HDFN associated with this antibody. Methods: HDFN-related blood group serological testing, antibody identification and specific blood group antigen identification were performed on blood samples from the infant and the mother. The mother's Kidd blood group was analyzed by molecular biology methods. Clinical data of the infant and the mother were collected, and changes in bilirubin, hemoglobin (Hb), and other results during the disease progression of the infant were analyzed. Results: The infant was blood type B, Rh (D) positive, and Kidd blood group Jk (a-b+). The mother was blood type O, Rh (D) positive. Due to an IVS5-1 G>A mutation, the mother exhibited a Jk (a-b-) phenotype. Anti-Jk3 antibodies were detected in the mother's plasma. The infant was diagnosed with HDFN due to anti-Jk3. During treatment, the total bilirubin (TBil) and indirect bilirubin (IBil) levels of the infant initially increased and then decreased, with peak monitored values of 228.2 μmol/L and 208.9 μmol/L, respectively. Hb decreased from 180 g/L at birth to 93 g/L. After phototherapy and symptomatic treatment, the infant's indicators stabilized, and the general condition improved. The infant was discharged after recovery. Conclusion: Clinically, HDFN caused by anti-Jk3 antibodies is relatively rare. For HDFN induced by this antibody, early detection, intervention, and treatment are essential to address the transfusion challenges posed by the extreme scarcity of Jk3-negative blood sources, thereby minimizing adverse outcomes in affected infants to the greatest extent possible.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.

Objective:To explore the key factors affecting health-related quality of life in children with brain tumors following initial diagnosis and to analyze its impact on survival and prognosis.Methods:Seventy-eight pediatric brain tumor patients who participated in a prospective cohort study between June 1st，2016 and June 30th，2021 were included for health-related quality of life assessment and long-term follow-up（median follow-up duration：52 months）.Results:The male-to-female ratio among the 78 children was 1.1：1，with a median age of 7.0（4.0，10.0）years. The scores of the Pediatric Quality of Life Inventory? 4.0 Generic Core Scales（PedsQL? 4.0）were（67.40±18.26）for parent proxy reports and（67.87±20.40）for child self-reports. Cronbach's α coefficients ranged from 0.790 to 0.927，with the intraclass correlation coefficient（ICC）was 0.673. According to the PedsQL? 4.0，impaired quality of life was observed in 50.0% of children by parent proxy report and 52.8% by child self-report，primarily affecting physical and role functioning. In addition，70% of caregivers reported impaired quality of life，with worry being the most prominent issue. Key factors affecting children's quality of life included radiotherapy，tumor stage，annual family income，and parents' marital status，while caregivers' quality of life was influenced by radiotherapy and the child's IgA levels（all P<0.05）. Children with decreased total scores，impaired physical functioning，or impaired emotional functioning on the PedsQL? 4.0 parent proxy report exhibited an increased risk of mortality（all P<0.05）. In multivariate Cox regression analysis，independent prognostic factors included a decrease in the total score on the PedsQL? 4.0 parent proxy report（ HR=6.702，95% CI：1.442-31.151， P<0.05），presence of hydrocephalus（ HR=33.602，95% CI：4.354-259.333， P<0.05），tumor recurrence（ HR=16.846，95% CI：3.158-89.852， P<0.05），and absence of hydrocephalus shunt surgery（ HR=13.428，95% CI：1.761-102.394， P<0.05）. Conclusion:The quality of life of newly diagnosed children with brain tumors is lower than that of healthy children，and quality of life is an important prognostic factor. Quality of life assessment should be an integral component of a comprehensive management program for children with brain tumors.

Objective To investigate the correlations of fibrinogen-to-albumin ratio(Fib/Alb),soluble myeloid cell triggering receptor-like transcript factor-1(sTLT-1)and neutrophil gelatinase-as-sociated lipocalin(NGAL)in peripheral blood at admission with the risk of poor prognosis in patients with acute thoracoabdominal trauma and their early warning values.Methods A prospective study was conducted in 152 patients with acute thoracoabdominal trauma in the hospital from January 2022 to May 2024.The patients were divided into good prognosis group(n=120)and poor prognosis group(n=32)according to their prognosis.Baseline data and the levels of Fib/Alb,sTLT-1 and NGAL in peripheral blood at admission were compared between the two groups.The relationships between the levels of Fib/Alb,sTLT-1,and NGAL in peripheral blood at admission and the severity of trauma[the Circulation,Respiration,Abdomen,Movement,and Speech(CRAMS)score]and the risk of poor prognosis were analyzed.The early warning values of the levels of Fib/Alb,sTLT-1 and NGAL in peripheral blood at admission for the risk of poor prognosis were evaluated.Results The time from injury to admission in the poor prognosis group was longer than that in the good prognosis group,the CRAMS score,the Glasgow Coma Scale(GCS)score,and the levels of Fib,Alb and Fib/Alb in peripheral blood at admission in the poor prognosis group were lower than those in the good prognosis group,while the Sequential Organ Failure Assessment(SOFA)score and the levels of sTLT-1 and NGAL in peripheral blood at admission were higher than those in the good prognosis group,with statistically significant between-group differences(P＜0.05).The levels of Fib,Alb and Fib/Alb in peripheral blood at admission showed a decreasing trend,while the levels of sTLT-1 and NGAL showed an increasing trend in patients with mild,severe,and extremely severe trauma,with statistically significant differences(P＜0.05).Pearson correlation analysis showed that the level of Fib/Alb in peripheral blood at admission(r=0.839)was positively correlated with the CRAMS score,while the levels of sTLT-1 and NGAL(r=-0.832,-0.808)were negatively cor-related with the CRAMS score(P＜0.05).Logistic regression analysis showed that after adjusting for confounding factors,the levels of Fib/Alb(OR=0.769),sTLT-1(OR=1.562)and NGAL(OR=1.575)in peripheral blood at admission were still independently correlated with the risk of poor prognosis(P＜0.05).The receiver operating characteristic(ROC)curve showed that the area under the curve(AUC)for the combined early warning of the risk of poor prognosis by the levels of Fib/Alb,sTLT-1,and NGAL in peripheral blood at admission was 0.918,which was superior to the early warning value of individual indicators(Z=2.992,2.291,2.082,P＜0.05).Conclusion The levels of Fib/Alb,sTLT-1 and NGAL in peripheral blood are closely related to the severity of trauma and prognosis in patients with acute thoracoabdominal trauma.Combined detection has a certain ear-ly warning value for the risk of poor prognosis and can be used as potential factors for clinical assess-ment of trauma condition and early warning of the risk of poor prognosis.

Objective: To investigate the value of metagene next⁃generation sequencing ( mNGS) in the detection of pathogens in patients with pulmonary infection. Methods: A retrospective analysis was performed on clinical data from 434 patients with pulmonary infections admitted over the past four years. Based on the presence of underlying comorbidities , patients were divided into underlying disease group (n = 262) and non⁃underlying disease group (n = 172) . Pathogen detection was conducted using both mNGS and conventional tests. Clinical and laboratory parameters , radiographic findings , and pathogen detection results were systematically analyzed. The diagnostic performance of the two methods in identifying causative pathogens of pulmonary infections was compared. Results: The positive rate of mNGS in 434 patients was higher than that of conventional tests , and the difference was statisti⁃cally significant (P < 0. 05) . The efficacy of mNGS in detecting bacteria and viruses was significantly higher than that of conventional tests , and the difference was statistically significant (P < 0. 05) . Although the fungal detection rate of mNGS was higher than that of conventional tests , the difference was not statistically significant. Among them , the detection rates of Mycobacterium tuberculosis , Mycoplasma pneumoniae , Haemophilus influenzae , Strepto⁃ coccus pneumoniae , Streptococcus constellation , Staphylococcus aureus and Aspergillus fumigatus were significantly higher than those of conventional tests , and the difference was statistically significant (P < 0. 05) . Subgroup analy- sis showed that the proportion of males , hospital stay , smoking prevalence and average age in the underlying dis- ease group were higher than those in the non-underlying disease group , and the difference was statistically signifi- cant (P < 0. 05) , while there were no significant differences in antibiotic use and endotracheal intubation rate be- tween the two groups. The most common pathogens detected by mNGS in the underlying disease group were Myco⁃ bacterium tuberculosis , Haemophilus influenzae , Streptococcus pneumoniae , Pseudomonas aeruginosa , human herpes⁃ virus type 4 and Aspergillus fumigatus , while the most common pathogens in the non-underlying disease group were Mycobacterium tuberculosis , Haemophilus influenzae , Streptococcus pneumoniae , Mycoplasma pneumoniae and Kleb⁃ siella pneumoniae. The positive rate of mNGS in the two groups was significantly higher than that of conventional tests , and the difference was statistically significant (P < 0. 05) , while the difference in the positive rate of mNGS between the two groups was not statistically significant. Conclusion mNGS has significant advantages over con- ventional tests of pathogen in lung infection , and is less affected by underlying diseases , which can provide an etio- logical basis for lung infection.

Ion concentration polarization (ICP) is an electrical transport phenomenon that occurs at the micro-nano interface under the action of an applied electric field, and the ICP phenomenon can be used to enrich charged particles with high efficiency. The microfluidic chip has the advantages of high precision, high efficiency, easy integration and miniaturization in biochemical analysis, which provides a new solution and technical way for biochemical analysis. In response to the demand for the detection of trace charged target analytes in sample solution, the advantages of high enrichment multiplicity, convenient operation and easy integration of ICP are utilized to provide an effective way for microfluidic biochemical detection. The combination of ICP phenomenon and microfluidic analysis technology has been widely used in the fields of pre-enrichment of charged particles, separation of targets, and detection of target analytes in biochemical analysis. In this paper, the principle of ICP and the microfluidic ICP chip are briefly introduced. Under the action of external electric field, the co-ions pass through the ion-selective nanochannel, the counterions are rejected at the boundary of nanochannel to form a depletion zone, and the charged samples will be enriched at the boundary of the depletion zone. Then the preparation techniques and methods of ICP chips are summarized. Among them, the design of microfluidic channel structure and the preparation and design of nanostructures are emphasized. The basic single-channel structure is analyzed, and the parallel-channel structure as well as the integrated multi-functional microfluidic ICP chip are sorted out and summarized. The preparation methods of nanostructures in ICP chips and their respective advantages and disadvantages are listed, and it is summarized that the current mainstream means are the embedding method and the self-assembly method, and attention is paid to the design of nanostructures preparation methods by both of them. In addition, this paper also discusses how to optimize the enrichment efficiency of ICP chip, through the introduction of multi-field coupling, valve control and other means to achieve the optimization of the enrichment efficiency of target substances. Meanwhile, this paper provides a classified overview of the progress of application of ICP chips in biochemical analysis and detection. ICP chips have been widely used in the research and development of biosensors, which can be used for the enrichment and separation of a variety of analytes including small molecules, nucleic acids, proteins, and cells, etc. By changing the design of microfluidic structures, integrating detection methods and modifying specific antibodies, ICP chips have shown great potential in the fields of rapid enrichment and pre-processing of targets, separation of targets and highly sensitive detection. Finally, it is pointed out that ICP chips are facing challenges in improving enrichment efficiency and selectivity, and solving the problems of fluid control, mixing and transport to match the biological properties of target assay, and that microfluidic ICP chips have been continuously promoting the development of ICP chips through the improvement of materials, chip design and integration of multifunctional units, opening up new possibilities in the field of biochemical analysis methods and applications. It can be seen that microfluidic ICP chips have the advantages of low sample flow rate, good separation and enrichment, high detection efficiency, and easy integration and miniaturization, which have shown good research significance and practical prospects in the field of biochemical detection.

Objective:To explore brain network properties and their relationship with cognitive function in children with spastic cerebral palsy (SCP) using diffusion tensor imaging (DTI) based graph theory analysis.Methods:The study was a cross-sectional study. Clinical and imaging data of 21 children with SCP (SCP group) and 32 healthy children (control group) who underwent cranial MRI at the Affiliated Hospital of Zunyi Medical University from August 2020 to April 2022 were analyzed retrospectively. 3D-T 1WI, DTI and Wechsler Intelligence Scale were assessed for all subjects. The Wechsler Intelligence Scale included the verbal comprehension index (VCI), the processing speed index (PSI), the work memory index (WMI), and the perceptual reasoning index (PRI), etc., and ultimately the full scale intelligence quotient (FSIQ) scores were obtained based on the indices of each subscale. Independent samples t-test was used to analyze the differences in the small world attributes [small-world index (σ), normalized shortest path length (λ), normalized clustering coefficients (γ)], global attributes [global efficiency (Eglob), local efficiency (Eloc), characteristic path length (Lp), clustering efficiency (Cp)] and node attributes [degree centrality(DC), nodal efficiency (Ne), betweeness centrality (Bc), nodal shortest path length (NLp), nodal clustering efficiency, nodal local efficiency] between two groups of children′s brain networks. Brain network indicators with statistically significant differences between the 2 groups were correlated with Wechsler Intelligence Scale scores using Spearman. Results:The FSIQ scores on the Wechsler Intelligence Scale and the VCI, WMI, PSI, and PRI were lower in the SCP group than in the control group, and the differences were all statistically significant (all P<0.05). Both groups of children′s brain networks had small world properties. Compared with the control group, Eglob decreased, Lp and λ increased in the SCP group (all P<0.05). Compared with the control group, DC and Ne in multiple brain regions decreased, NLp increased in the SCP group (all P<0.05, FDR corrected). Correlation analysis showed that DC in the right parsopercularis was positively correlated with FSIQ, VCI, WMI and PRI( r=0.53, 0.47, 0.47, 0.60, P=0.019, 0.045, 0.044, 0.020, respectively); NLp in the right parsopercularis was negatively correlated with PRI( r=-0.56, P=0.030); Ne in left paracentral, the right parsopercularis, right precentral, right postcentra were positively correlated with PRI( r=0.62, 0.56, 0.53, 0.54, P=0.015, 0.031, 0.044, 0.039, respectively); Ne in the right precentral was positively correlated with WMI ( r=0.48, P=0.039) in the SCP group. Conclusions:There are changes in the topological attributes of global and multiple regional brain networks in SCP. The changes in the attributes of nodes in the right parsopercularis, right precentral, right postcentral, and left paracentral could reflect cognitive dysfunction in children with SCP.
