Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

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.

Objective:To observe the effect of electroacupuncture on depression in chronic pain mice; To explore its mechanism.Methods:36 C57BL/6J mice were divided into a blank control group, a sham-operation group, a model group, and an electroacupuncture group using a random number table method, with 9 mice in each group. The chronic compression injury model of sciatic nerve was established in the model group and electroacupuncture group. Mechanical pain threshold (MWT) and latent heat wave leg reflex (TWL) were measured on preoperative day 1 and postoperative days 4, 7, 14, 21, and 35. Electroacupuncture treatment was performed on the 14th day after modeling, and on the 35th day after modeling, open field experiments, elevated cross maze experiments, forced swimming experiments, and tail suspension experiments were conducted to evaluate depressive like behavior in mice. Western blot was used to detect the protein expressions of glutamate receptor 1 (GluA1), glutamate receptor 2 (GluA2), human glucose transporter 3 (GLUT3), and calmodulin dependent protein kinase Ⅱ (CaMKⅡ) in the hippocampus of each group of mice; GluA1 positive cells in the hippocampus of mice was observed using immunofluorescence technology.Results:Compared with the blank group, the MWT and TWL value of the model group decreased ( P<0.05) on postoperative days 4, 7, 14, and 21. Compared with the model group, the electroacupuncture group had a longer stay time in the central area of the open field ( P<0.01), an increased percentage of stay time and activity frequency in the elevated arm opening ( P<0.01), a shorter static time for forced swimming ( P<0.01), and a shorter immobility time for the suspended tail ( P<0.01). Compared with the model group, the expressions of GluA1, GLUT3, GluA2, and CaMKⅡ proteins in the hippocampus of mice in the electroacupuncture group increased ( P<0.05), and the number of GluA1 positive cells increased ( P<0.05). Conclusion:Electroacupuncture can affect synaptic plasticity by regulating the AMPA receptor in the hippocampal region, thereby improving depressive mood caused by chronic pain.
