ObjectiveTo explore the application of virtual reality biofeedback training combined with oral localization therapy in dysphagia after oral cancer surgery. MethodsFrom May, 2023 to July, 2024, 86 patients with dysphagia after oral cancer surgery in Zhejiang Provincial People's Hospital were randomly divided into control group (n = 43) and experimental group (n = 43). The control group received conventional swallowing function training, while the experimental group added virtual reality biofeedback training combined with oral positioning therapy, for four weeks. The Standardized Swallowing Function Assessment Scale (SSA), Functional Oral Intake Scale (FOIS) and M.D.Anderson Dysphagia Inventory (MDADI) were used for evaluation before intervention, and two weeks, four weeks and eight weeks after intervention. ResultsFor scores of SSA , the main effects of group (F = 150.190, P < 0.001, η²_p = 0.641) and time (F = 230.870, P < 0.001, η²_p = 0.733), as well as the interaction effect (F = 16.910, P < 0.001, η²_p = 0.168) were all significant. For scores of FOIS, the main effects of group (F = 59.601, P < 0.001, η²_p = 0.415) and time (F = 89.464, P < 0.001, η²_p = 0.516), as well as the interaction effect (F = 7.990, P < 0.001, η²_p = 0.087) were all significant. For scores of MDADI, the main effects of group (F = 33.133, P < 0.001, η²_p = 0.283) and time (F = 49.650, P < 0.001, η²_p = 0.371), as well as the interaction effect (F = 3.224, P = 0.023, η²_p = 0.037) were all significant. ConclusionVirtual reality biofeedback training combined with oral localization therapy could improve the swallowing function, oral feeding ability and overall quality of life of patients with dysphagia after oral cancer surgery.

In recent years,the prevalence of overweight/obesity in solid organ transplant recipients has been rising rapidly.Clinical research evidence on obesity in solid organ transplant recipients has been increasing,but there is a lack of standardized diagnostic and treatment guidelines and comprehensive management pathways to guide clinical practice.Based on this,the Expert Consensus on Weight Management in Overweight or Obese Adult Solid Organ Transplant Recipients(2025 Edition)was organized and written by experts from the Diabetes Professional Committee of the Chinese Research Hospital Association.This consensus mainly provides recommendations on the epidemiological data,diagnostic criteria,screening and assessment methods,management pathways,and intervention strategies for overweight/obesity in solid organ transplant recipients.It aims to further improve the management level of medical workers engaged in the whole process of organ transplantation for the population with overweight/obesity combined with solid organ transplantation,standardize clinical diagnosis and treatment,improve patient prognosis,and enhance quality of life.

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.

Objective:To Analyze the psychological behavior characteristics of young military personnel stationed in Xinjiang,providing a basis for the mental health education of military personnel.Methods:Using the Symptom Checklist-90(SCL-90)and a cluster sampling method,the mental health screening of young military personnel in Xinjiang was conducted from July to August 2024,with 2 218 valid questionnaires collected.Total scores and subscale scores of the SCL-90 were compared across demographic variables,including ethnicity,personnel categories,education level,marital status,singleton status,and urban/rural background.Results:The positive symptom rate was 1.53%(34/2218).Statistically significant differences(P＜0.05)were observed in total SCL-90 scores and subscale scores among the young military personnel with different ethnicities,personnel categories,education levels,marital statuses,singleton statuses,etc.Conclusions:To address the evolving demands of military psychological services,frontline-oriented interventions should be prioritized,leveraging the roles of psychologists and mental health officers.Institutional safeguards for basic needs,enhanced military support systems,and strengthened humanistic care are critical to improving psychological resilience among personnel,thereby bolstering combat readiness and stability.

Objective To investigate alterations in interhemispheric functional connectivity(FC)in the cerebral cortices connected via the corpus callosum in patients with Alzheimer's disease(AD),and to explore their relationships with cognitive function and activities of daily living.Methods Resting-state functional magnetic resonance imaging data were collected from 28 patients with Alzheimer's dementia(d-AD),47 patients with mild cognitive impairment(MCI),and 37 healthy controls(HC).Using a trancallosal tract template,32 pairs of homologous cortical brain regions directly connected to 32 subregions of the corpus callosum were selected as regions of interest for interhemispheric FC analysis.Further correlation analyses were performed between FC values in patient groups and their scores on the Montreal Cognitive Assessment-Basic(MoCA-B)Scale and the Activities of Daily Living(ADL)Scale.Results Compared with HC group,both MCI and d-AD groups exhibited hyperconnectivity(significantly increased FC)in interhemispheric non-homologous brain regions.Specifically,hyperconnectivity in the MCI group was scattered across the frontal,parietal,temporal,and occipital lobes,while in the d-AD group,it was concentrated within the precentral and postcentral gyri.Notably,hyperconnectivity involving the prefrontal and occipital lobes in the MCI group showed significant declines in the d-AD group.The interhemispheric homologous FC in the d-AD group reduced more significantly than the MCI group.Additionally,in the d-AD group,2 interhemispheric FC within the prefrontal lobe(between the bilateral orbital parts of the inferior frontal gyrus,and between the left medial frontal gyrus and the right middle frontal gyrus)were correlated with MoCA-B scores,and 2 FC(between the bilateral middle occipital gyri,and between the left inferior parietal lobule and the right middle frontal gyrus)were correlated with ADL scores.Conclusion MCI and d-AD exhibit distinct patterns of interhemispheric FC alterations,and the interhemispheric FC changes in AD patients are non-progressive.The close relationships between interhemispheric homologous/non-homologous FC and MoCA-B/ADL scores in d-AD patients provide an objective basis and reference for clinical neuromodulation.

BACKGROUND: Several studies have demonstrated the occurrence of secondary tumors as a rare but significant complication of chimeric antigen receptor T (CAR-T) cell therapy, underscoring the need for a detailed investigation. Given the limited variety of secondary tumor types reported to date, a comprehensive characterization of the various secondary tumors arising after CAR-T therapy is essential to understand the associated risks and to define the role of the immune microenvironment in malignant transformation. This study aims to characterize the immune microenvironment of a newly identified secondary tumor post-CAR-T therapy, to clarify its pathogenesis and potential therapeutic targets. METHODS: In this study, the bone marrow (BM) samples were collected by aspiration from the primary and secondary tumors before and after CD19 CAR-T treatment. The CD45 + BM cells were enriched with human CD45 microbeads. The CD45 + cells were then sent for 10× genomics single-cell RNA sequencing (scRNA-seq) to identify cell populations. The Cell Ranger pipeline and CellChat were used for detailed analysis. RESULTS: In this study, a rare type of secondary chronic myelomonocytic leukemia (CMML) were reported in a patient with diffuse large B-cell lymphoma (DLBCL) who had previously received CD19 CAR-T therapy. The scRNA-seq analysis revealed increased inflammatory cytokines, chemokines, and an immunosuppressive state of monocytes/macrophages, which may impair cytotoxic activity in both T and natural killer (NK) cells in secondary CMML before treatment. In contrast, their cytotoxicity was restored in secondary CMML after treatment. CONCLUSIONS This finding delineates a previously unrecognized type of secondary tumor, CMML, after CAR-T therapy and provide a framework for defining the immune microenvironment of secondary tumor occurrence after CAR-T therapy. In addition, the results provide a rationale for targeting macrophages to improve treatment strategies for CMML treatment.

Objective:To quantitatively evaluate the effects of left bundle branch block（LBBB）on left ventricular structure，function and myocardial perfusion using left ventricular pressure-strain loop and single photon emission computed tomography（SPECT），and to investigate the relationship between myocardial work，myocardial perfusion and pathological changes of left ventricular remodeling in left bundle branch block induced cardiomyopathy（LBBB-CM）.Methods:Fourteen male beagle dogs were selected，and the main trunk of the left bundle branch was ablated to create an LBBB dog model. Electrocardiogram（ECG），transesophageal echocardiography and arterial blood pressure data of LBBB dogs were collected before and 12 months after the ablation of left bundle branch trunk. Global and segmental myocardial work parameters were obtained by left ventricular pressure-strain loop. The differences of above parameters between baseline and 12 months after the ablation of left bundle branch were compared. SPECT was performed in LBBB dogs 12 months after the creation of LBBB. The hearts were harvested for anatomy observation and histopathological analysis in LBBB dogs and another 7 male beagle dogs（normal control group）matched by age and weight. The correlation between myocardial perfusion（percentage of regional tracer uptake）and myocardial work parameters，myocardial fibrosis in LBBB dogs were analyzed.Results:Compared with baseline，the left ventricular end-diastolic volume of 12 months after the ablation increased［（20.78 ± 5.32）ml vs（26.71 ± 7.94）ml， P = 0.003］，left ventricular ejection fraction decreased［（59.17 ± 5.67）% vs（47.69 ± 5.45）%， P<0.001］；left ventricular global/segmental longitudinal strain，global/segmental constructive work and global/segmental work efficiency decreased（all P<0.05），left ventricular global/segmental wasted work increased（all P<0.001）. Heterogenous perfusion defect was observed in LBBB dogs by SPECT，compared with lateral wall segments，the percentage of regional tracer uptake of septum was decreased（all P<0.05）. Gross anatomical and myocardial pathological changes were manifested as cardiomegaly，flaky or focal grayish thickening of endocardium，cardiomyocyte degeneration and fibrosis. Compared with normal control group，the collagen fiber volume fraction（CVF）in all segmental endocardium and partial segmental myocardium of LBBB dogs were significantly increased（all P<0.05）. Percentage of regional tracer uptake was positively correlated with segmental myocardial work（SMW）and segmental myocardial efficiency（SWE）（ r s = 0.49，0.31；both P<0.001），and negatively correlated with CVF and segmental wasted work（SWW）（ r s = -0.51，-0.49；both P<0.001）. Conclusions:Isolated LBBB is not benign，which can result in left ventricular remodeling，decreased cardiac constructive function，abnormal myocardial perfusion，endocardial fibrosis and myocardial fibrosis.The parameters of myocardial work assecsed by echocardiograpgy and myocardial perfusion，as non-invasive examination，can to some extent reflect the degree of left ventricular remodeling in LBBB-CM.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
