ObjectiveTo delineate imaging findings using an imaging platform and investigate the correlation between MRI characteristics of spinal cord atrophy and clinical diagnosis in children with spinal cord injury (SCI). MethodsImaging data of 150 children with SCI admitted to Beijing Bo'ai Hospital, China Rehabilitation Research Center, from January, 2002 to March, 2024 were collected and imported into the imaging platform. The anteroposterior and transverse diameters of the middle part of the spinal cord at the cross-section with the most severe atrophy were measured, and the relevant indicators of the previous normal spinal cord segment were measured as controls; the radiomic features were extracted. Clinical data of the children including gender, age, cause of injury, sensory level, motor level, spinal cord injury level, injury severity and disease course were collected. ResultsSpinal cord atrophy was identified in 81 cases (54%), among which 78 cases (96%) were American Spinal Injury Association Impairment Scale (AIS) grade A and 3 cases (4%) were AIS grade C. The upper boundary of the spinal cord atrophy site strongly correlated with the injury level, motor level and sensory level (r > 0.8, P < 0.001). ConclusionMore than half of children with SCI may develop secondary spinal cord atrophy, the vast majority of whom suffer from complete spinal cord injury; the upper boundary of spinal cord atrophy is correlated with the injury level.

Metabolic associated fatty liver disease (MAFLD) is fundamentally driven by an imbalance in hepatic fatty-acid flux: the influx of fatty acids exceeds the liver’s capacity for disposal, resulting in excessive hepatic lipid accumulation, predominantly in the form of triglycerides (TGs). The occurrence and progression of MAFLD depend on disordered regulation across multiple metabolic steps, including fatty-acid uptake, de novo lipogenesis (DNL), fatty-acid oxidation (FAO), and very low-density lipoprotein (VLDL) export. Forkhead box protein O1 (FOXO1) is a key transcriptional regulator within the hepatic network coordinating glucose and lipid metabolism. Under metabolic stress and insulin resistance (IR), FOXO1 expression is frequently increased, whereas its inhibitory phosphorylation is reduced. These changes enhance FOXO1 nuclear localization and transcriptional activity, thereby reprogramming the expression of genes related to metabolism in the liver. Because hepatic lipid deposition is the central pathological feature of MAFLD, the functional status of FOXO1 directly influences hepatic lipid homeostasis. Growing evidence suggests that FOXO1 can exert bidirectional, environment-dependent effects on hepatic lipid accumulation; however, the molecular basis for this functional switch remains incompletely understood. This review systematically summarizes the biological functions and regulatory mechanisms of FOXO1 and its roles in hepatic lipid metabolism, with a particular focus on its crosstalk with insulin signaling. FOXO1 expression is shaped by RNA modifications and epigenetic regulation mediated by non-coding RNAs. Its transcriptional output is precisely governed by post-translational modifications—such as phosphorylation and acetylation—as well as by coordinated nucleocytoplasmic shuttling. Notably, these regulatory patterns vary markedly across nutritional states, degrees of insulin resistance, and stages of disease. In the fed state, insulin/IGF-1 signaling activates the PI3K-AKT pathway, promoting the inhibitory phosphorylation of FOXO1 and facilitating additional modifications, including acetylation, methylation, and ubiquitination. Together, these events drive FOXO1 export from the nucleus and dampen its transcriptional activity, suppressing gluconeogenesis and constraining lipogenic programs. Conversely, during fasting or when insulin signaling is weakened, FOXO1 inhibition is relieved. FOXO1 accumulates in the nucleus, binds to DNA, and regulates the transcription of downstream target genes. Mechanistically, FOXO1 can aggravate hepatic lipid accumulation by activating genes involved in TG synthesis while repressing FAO-related pathways, thereby favoring storage over oxidation. However, under specific conditions, FOXO1 may also alleviate the hepatic lipid burden by promoting TG hydrolysis and enhancing VLDL secretion, thereby reducing the net hepatic lipid load. In addition, lipotoxic signals mediated by ceramides and diacylglycerols (Cer/DAG) activate atypical protein kinase C (aPKC), further exacerbating the disruption of the AKT-FOXO1 axis. This vicious cycle ultimately produces a metabolic paradox in which increased hepatic glucose output coexists with persistent, insulin-independent lipogenesis, accelerating MAFLD progression. Importantly, FOXO1 regulation is not uniform: during early metabolic overload, insulin-mediated suppression may remain effective, whereas in advanced insulin resistance, the loss of AKT control permits sustained FOXO1 activity. Such stage-dependent dynamics may help explain why FOXO1 can either promote steatosis or, in certain contexts, support programs that facilitate lipid turnover. Accordingly, interventions should be liver-specific and tuned to the disease stage, aiming to curb maladaptive FOXO1 signaling while preserving its capacity to promote triglyceride hydrolysis and VLDL secretion when advantageous. Overall, this review offers an important perspective on MAFLD pathogenesis, emphasizing FOXO1 as a potential therapeutic target and providing a theoretical basis for developing liver-specific, disease-course-dependent precision interventions.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.

Objectives  There are only a few quantitative studies focusing on religious and cultural barriers among non-Japanese-speaking patients and discussing the association in Japanese healthcare institutions. This study aims to clarify the association between the religious and cultural backgrounds of non-Japanese-speaking patients and their difficult experiences in the healthcare institutions.Methods  The Google Forms questionnaire survey was conducted in four languages (Plain Japanese, English, Chinese, Vietnamese) among non-Japanese-speaking patients who had visited a Japanese healthcare institution. Of the 376 respondents (response rate: 19.7%), 350 were included in the analysis while excluding invalid responses. The association between their religions and difficulties were examined by logistic regression analysis with putting their gender, age, Japanese language proficiency, the purpose of visit and the way to communicate in examination rooms as adjustment variables. Results  237 (67.7%) had no religion, 29 (8.3%) were Christian, 12 (3.4%) were Muslim, 22 (6.3%) were Hindu and 50 (14.3%) were Buddhist of those analyzed. Odds ratios for experiencing difficulties were significantly higher for Hindu (odds ratio ［95% confidence interval］＝6.35［1.51-26.77］) and Christian (3.67［1.27-10.61］) compared with those who do not have religion. Regarding difficulties, it was found that the half of Hindu respondents identified “food” (50%) indicating a religious and cultural background, while various difficulties were identified for Christian respondents including “religion” (22%), “culture” (22%), and “medical costs” (22%).Conclusions  This study demonstrated an association between religion and difficulties in Japanese healthcare institutions among non-Japanese patients with a large proportion of outpatients. It was observed that Christian and Hindu respondents were more likely to have difficult experiences in the healthcare institutions. The results of this study suggest a need for religious and cultural consideration in outpatient settings such as the use of healthcare interpreters and the practice of transcultural nursing by medical professionals.

Objective:To study the consistency between post-processing bone mineral density(BMD)values of multi-slice spiral computed tomography(MSCT)scan and the BMD value of quantitative computed tomography(QCT)for lumbar vertebra,so as to explore the feasibility of utilizing MSCT scan-based post-processing BMD values for lumbar vertebra in clinical practice.Methods:The MSCT equipment and QCT equipment were respectively adopted to conduct imaging scan for the L2-L4 of lumber vertebra of QRM-ESP145 European Spine Phantom(ESP),and L2-L4 of lumbar vertebra of adult sheep,and L2-L4 of lumbar vertebra of adult volunteer.The L2-L4 of ESP lumber vertebra and L2-L4 of lumbar vertebra of adult sheep were scanned respectively MSCT and QCT for three times,so as to measure BMD values.The L2-L4 of lumbar vertebrae of volunteers were scanned respectively by the two methods for one time according to the standard of clinical examination,which were reconstructed by three times so as to obtain mean of them.The BMD values of QCT scan were set as control group,and the BMD values of MSCT scan were set as experiment group.The experiment group was further divided into experiment 1 group[two dimension(2D)regional volumetric BMD values of the lumbar vertebra]and experiment 2 group[three dimension(3D)global volumetric BMD post-processing of the lumbar vertebra]according to the reliability of experiment.Then,the consistency between the MSCT 3D post-processing BMD values of three groups and QCT-measured BMD values was compared and analyzed.Results:The MSCT 3D post-processing BMD values of L2-L4 of ESP lumbar vertebra of three groups were respectively(120.83±0.97),(199.57±0.54)and(119.19±1.04)mg/cm3,and that of L2-L4 of lumbar vertebra of adult sheep of three groups were respectively(414.89±1.72),(410.50±0.77)and(420.25±2.71)mg/cm3,and that of L2-L4 of lumbar vertebra of volunteer were respectively(141.22±0.09),(137.38±0.37)and(152.03±1.03)mg/cm3.There were not statistically significant differences in BMD values between MSCT examination and QCT examination(P＞0.05).Conclusion:MSCT 3D post-processing BMD values on lumbar vertebra has high consistency with that of QCT measurements,which post-processing technique can replace QCT to conduct BMD examination,and reduce unnecessary radiation exposure and examination costs for patients.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective:To investigate the association of serum levels of micro RNA-126(miR-126),C-peptide,secreted phospholipase A2(sPLA2)with carotid atherosclerotic plaque(CAP)and prognosis in patients with coronary heart disease(CHD).Methods:A total of 114 patients with carotid atherosclerotic coronary heart disease(CAS-CHD)admitted to-Baoding Third Central Hospital between February 2020 and February 2021 were enrolled.Patients were divided into stable plaque group(n=68)and unstable plaque group(n=46)according to carotid ultrasound findings.Serum levels of miR-126,C-peptide and sPLA2 were compared between two groups.Pearson correlation analysis was used to determine the as-sociation of miR-126,C-peptide and sPLA2 with plaque Crouse score.Binary Logistic regression analysis was used to in-vestigate the association of miR-126,C-peptide and sPLA2 with unfavorable outcome.The predictive performance of the combined detection of miR-126,C-peptide,and sPLA2 for unfavorable outcome in CAS-CHD patients was evalua-ted using the receiver operating characteristic(ROC)curve analysis.Results:Compared with patients in the stable plaque group,those in the unstable plaque group had significant higher miR-126[(0.99±0.30)vs.(0.81±0.24)],carotid inti-ma-media thickness(IMT)[(1.67±0.42)mm vs.(1.31±0.51)mm]and plaque Crouse score[(5.93±1.42)points vs.(4.30±1.32)points](P＜0.001 all).Pearson correlation analysis indicated that miR-126,C-peptide and sPLA2 were positively correlated with plaque Crouse score(r=0.267,0.309,0.351,P＜0.01 all).Binary Logistic regression a-nalysis showed that age[odds ratio(OR)=1.509,95％CI 1.055～2.157],miR-126(OR=60.595,95％CI 1.252～2932.237),C-peptide(OR=2.870,95％CI 1.249～6.595),sPLA2(OR=1.068,95％CI 1.016～1.124)and plaque Crouse score(OR=4.491,95％CI 1.824～11.059)were independently associated with unfavorable outcome(P＜0.05 or＜0.01).The area under the joint prediction curve(AUC)was 0.898(95％CI 0.825～0.948),which was significantly higher than miR-126(AUC=0.722,95％CI 0.628～0.804),C-peptide(AUC=0.818,95％CI 0.732～0.886)and sPLA2(AUC=0.806,95％CI 0.719～0.876)alone(Z=3.140,3.161,2.930,P＜0.01 all).Conclusion:Serum miR-126,C-peptide and sPLA2 levels were significantly correlated with the severity of carotid atherosclerosis in coronary heart disease.Combined detection of these three biomarkers may predict unfavorable outcome in these patients.

This study aims to investigate the effect of Lactiplantibacillus plantarum LP12 on obe-sity prevention.In our study,Lactiplantibacillus plantarum LP12 was added to the diet for feed-ing,and the blood biochemistry status of rabbit,as well as the antioxidant effect of serum and liver samples were analyzed by determining the body weight change and feed intake of Japanese White rabbits.The changes in colony structure and abundance were also analyzed by 16S rDNA sequen-cing.The results showed that supplementation of Lactiplantibacillus plantarum LP12 inhibits weight gain,decreases serum glucose and ALT levels,and increases SOD activity in the liver.16S RNA gene sequencing analysis showed that the addition of Lactiplantibacillus plantarum LP12 increases the abundance of Bacteroidetes and Desulfovibrioides at the phylum level,and the supple-mentation of Lactiplantibacillus plantarum LP12 increases the abundance of Muribaculaceae at the genus level.Predictive analysis of microbiota function revealed that the supplementation of Lactiplantibacillus plantarum LP12 positively regulated iron-sulfur clusters and Zn-dependent proteases.In conclusion,the addition of Lactiplantibacillus plantarum effectively inhibits weight gain in Japanese White rabbits,enhances the antioxidative activity of the liver,and induces altera-tions in the gut microbiota composition of these rabbits.These findings lay an experimental foun-dation for further exploring the mechanisms by which Lactobacillus plantarum LP12 exerts its preventive effects against obesity and promotes metabolic health.

Objective To explore the regulatory effect of moderate intensity aerobic exercise on glu-cose and lipid metabolism disordersafter immune stimulation in high-fat diet induced insulin resistance(IR)mice by inducing tolerance of trained immunity.Methods Eighteen of 70 male C57BL/6 male mice were randomly selected as the control group(CON group),while the remaining mice were subjected to high-fat diet intervention(HFD group)for 8 weeks.After modeling,six of the CON group and HFD group were measured their glucose and lipid metabolism and inflammation levels.The remaining mice in the HFD group were randomly divided into HFD sedentary group(HS group)and HFD exer-cise group(HE group),each of 16.The HE groups underwent a daily 60-minute running on a hori-zontal treadmill at 12 m/min,5 days a week for 8 weeks.After that,the CON,HS and HE groups were randomly divided into an immune stimulation group(lipopolysaccharides,LPS group)and a con-trol group(phosphate buffered saline,PBS group),with 6 in CON-PBS and CON-LPS groups,and 8 in HS-PBS,HS-LPS,HE-PBS and HE-LPS groups.The LPS group received intraperitoneal injec-tion of LPS as an immune stimulus,and were taken samples 24 hours after intervention.During the intervention period,the body weight,food intake,fasting blood glucose(FBG),glucose tolerance,and insulin tolerance were tested for all groups.Then,the serum blood lipid level was tested.More-over,the levels of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1β)and interleukin-10(IL-10)in serum were detected by using the enzyme-linked immunosorbent assay,while the protein expression of IL-1β,IL-10,induciblenitricoxidesynthase(iNOS)andarginase-1(Arg-1)were measured by using Western Blot.Results(1)After 8 weeks of high-fat diet intervention,compared with the CON group,there was a significant increase in the body weight,food intake,and FBG,the level of TNF-α and IL-1β in serum and expressions of IL-1β and iNOS in liver,skeletal muscle and adipose tissue,but a significant decrease in glucose and insulin tolerance,the level of anti-in-flammatory factor IL-10,as well as IL-10 and Arg-1 in liver and Arg-1 in adipose tissues in group HFD(P<0.01,P<0.05).(2)After 8 weeks of diet intervention,the body weight of group HS-PBS was still significantly higher than group CON-PBS(P<0.01).However,no significant differences were found between group CON-PBS and HS-PBS in other indicators(P>0.05).After LPS intervention,the food intake of both CON-LPS and HS-LPS groups was significantly lower than the corresponding PBS group(P<0.05).However,the levels of FBG,TG,TC,LDL-C,TNF-α and IL-1β in serum,IL-1β and iNOS in liver and adipose tissues,and iNOS in skeletal muscles of group HS-LPS were signif-icantly higher compared with group HS-PBS and CON-LPS(P<0.05).Meanwhile,the levels of IL-10 in serum,skeletal muscles and adipose tissues,and Arg-1 in skeletal muscles and adipose tissues of group HS-LPS decreased significantly compared with group HS-PBS and CON-LPS(P<0.05).(3)Af-ter simultaneous aerobic exercise intervention,there were no significant differences between group HE-LPS and HE-PBS in FBG,TC,LDL-C,TNF-α,IL-1β and IL-10 in serum,as well as IL-1β,iN-OS and IL-10 in the liver,skeletal muscles and adipose tissues(P>0.05).Moreover,thelevels of FBG,TG,TC,TNF-α,IL-1β in serum,and IL-1β and iNOS in the liver,skeletal muscle and adi-pose tissue decreased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Howev-er,the levels of IL-10 in the serum and liver,and IL-10 and Arg-1 in skeletal muscles and adi-pose tissues increased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Conclu-sion Eight-week aerobic exercise can effectively relieve the glucose and lipid metabolism disorder after immune stimulation in IR mice,which may be related to the stimulation of immunologic tolerance in innate immune cells,thereby reducing the excessive inflammatory response caused by secondary im-mune stimulation.
