Objective:To assess the effectiveness of kinetic parameters of 18F-prostate specific membrane antigen (PSMA)-1007 PET/MR in distinguishing tumor recurrence (TR) from radiation necrosis (RN) in glioma patients. Methods:From January 2023 to June 2023, imaging data of 10 patients (6 males, 4 females; media age of 39.5 years) with gliomas who were suspected of recurrence and were referred for 18F-PSMA-1007 PET/MR scans at Sun Yat-Sen University Cancer Center were retrospectively analyzed. Static parameters from 18F-PSMA-1007 PET scans, including SUV max, SUV mean, metabolic tumor volume (MTV), and total lesion′s PSMA (TLP), as well as dynamic parameters including K 1, k 2, k 3, k 4, net influx rate (K i), and volume of distribution ( Vt) were obtained by using compartmental and multigraphical models. Additionally, parameters from dynamic contrast-enhanced MRI (DCE-MRI) were collected. Mann-Whitney U test was used to compare parameter differences between TR and RN groups. Spearman rank correlation analysis was used to explore the correlation between K i and DCE-MRI parameters. Results:Finally, 8 cases were diagnosed as TR and 2 cases were diagnosed as RN. The kinetic compartmental model-based evaluation determined that irreversible 2-tissue model (2T3K) provided the best-fitting results. The differences in SUV mean (median: 2.48 vs 0.89; Z=-2.09, P=0.044), SUV max (median: 4.04 vs 1.40; Z=-2.09, P=0.044), and K i (median: 1.33×10 -2vs 3.87×10 -3;Z=-2.10, P=0.044) between TR and RN groups were statistically significant. Some parameters of DCE-MRI also showed differences between the two groups ( Z=-2.09, P=0.044 for all). The K i yielded moderate correlation with DCE-MRI parameter Ve ( rs=0.650, P=0.042), while correlations between K i and other DCE-MRI parameters were not significant ( rs values: from -0.207 to 0.632, all P>0.05). Conclusion:Dynamic and multi-parametric 18F-PSMA-1007 PET/MR system holds promise for accurately distinguishing TR from RN in treated glioma patients.

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.

Aim To investigate the effect of icariin(ICA)on chronic ulcerative colitis(UC)in mice.Methods Male SPF-grade C57BL/6J mice were ran-domly divided into the control group,model group,low-dose ICA group,and high-dose ICA group.Except for the control group,the rest of the mice were established as chronic UC models.Expressions of tight junction proteins,inflammatory factors,fibrosis markers,macro-phage markers,and MAPK signaling pathways in the colonic epithelium of each group were determined by Western blot,qPCR,immunohistochemistry;the degree of intestinal damage and fibrosis was detected by HE and Masson staining;the co-localization of different macrophage markers with related factors was examined by immunofluorescence.Results Treatment of ICA significantly improved the general condition of chronic UC mice,decreased the infiltration of M1-type macro-phages and the secretion of pro-inflammatory factors,inhibited the MAPK signaling pathway,reduced the co-localization expression of M1-type macrophages with the MAPK signaling pathway,and downregulated the infiltration of M2-type macrophages and the secretion of pro-fibrotic factors in the colon.Conclusion ICA mitigates the inflammatory damage and fibrosis of colon in chronic UC mice.

Objective To summarize and analyze the clinicopathological characteristics,imaging manifestations,treatment and prognosis of anaplastic lymphoma kinase(ALK)-positive histiocytosis(APH)involving the central nervous system(CNS),so as to enhance understanding of this rare disease.Methods A retrospective analysis was conducted on 5 cases of CNS-involved APH diagnosed in Huashan Hospital,Fudan University between 2019 and 2023.Clinical,imaging and pathological data were collected,and supplemented by immunohistochemical staining(IHC),fluorescence in situ hybridization(FISH)and high-throughput sequencing for auxiliary diagnosis and molecular characterization.The findings were summarized and integrated with previous literature for a comprehensive analysis.Results All five patients were male,with a mean age of 27.6 years,in which 2 cases exhibited multi-system involvement,while 3 cases exhibited single system involvement.Imaging revealed multiple intracranial lesions in multi-system cases and solitary lesions in single system cases,with well-defined boundaries and homogeneous enhancement.Histologically,tumor cells were intermingled with lymphocytes,displaying an alternating"light and dark"pattern in 1 case.Granuloma-like structures were observed in 4 cases,along with frequent nuclear grooves,indentations and convolutions.Tumor cells usually infiltrated surrounding tissues.IHC demonstrated that tumors expressed histiocytic markers(CD68/CD163)and ALK predominantly expressed in the cytoplasm.FISH confirmed ALK gene rearrangements in all patients,while high-throughput sequencing identified KIF5B-ALK fusions in 2 cases.All single system CNS cases achieved complete remission after surgical resection with or without adjuvant chemotherapy/ALK inhibitors.Among multi-system cases,one achieved partial remission,and one experienced relapse and progression.Conclusion CNS APH is prone to preoperative misdiagnosis.Its histopathological features,ALK immunohistochemical expression,and ALK gene fusions are critical for diagnosis.Patients with single system involvement demonstrate overall superior outcomes compared to multi-system cases.Total resection is effective for localized disease,while multi-system cases require systemic therapy.Multidisciplinary collaboration is crucial for precise diagnosis and treatment.

Objective To investigate the efficacy of Lactobacillus plantarum ZG03(L.plantarum ZG03)for ameliorating oxidative stress in zebrafish.Methods We evaluated the growth pattern of L.plantarum ZG03,observed its morphology using field emission scanning electron microscopy,and assessed its safety and potential efficacy with whole-genome sequencing for genetic analysis.FITC-labeled ZG03 was used to observe its intestinal colonization in zebrafish.In a zebrafish model of 2%glucose-induced oxidative stress,the effect of ZG03 was evaluated by assessing the changes in neutrophils in the caudal hematopoietic tissue(CHT),superoxide dismutase(SOD)activity,reactive oxygen species(ROS)levels,and malondialdehyde(MDA)content.Liquid chromatography-mass spectrometry-based targeted metabolomics was used for analyzing short-chain fatty acids(SCFAs)in the zebrafish,and the antioxidant effects of the key metabolites(acetate,propionate,and caproate)were tested.Results On MRS agar,L.plantarum ZG03 formed circular,smooth,moist,and milky-white colonies with a rod-shaped cell morphology.Genomic analysis revealed abundant sugar metabolism gene clusters.After inoculation of FITC-labeled L.plantarum ZG03 in zebrafish,green fluorescence was clearly observed in the intestinal bulb,mid-intestine,and hind intestine.In zebrafish with glucose-induced oxidative stress,L.plantarum ZG03 significantly reduced ROS levels and the number of neutrophils in the CHT with increased SOD activity.L.plantarum ZG03 significantly increased the content of SCFAs including acetic acid,propionic acid,and caproic acid in zebrafish metabolites.In addition,sodium acetate,sodium propionate,and sodium caproate in the SCFAs significantly increased SOD activity in the zebrafish models.Conclusion L.plantarum ZG03 ameliorates oxidative stress in a glucose-induced zebrafish model through its metabolites,particularly the SCFAs including acetic acid,propionic acid and caproic acid.
