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.

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.

Objective:To investigate the efficacy, safety and possible mechanisms of celecoxib as an adjunctive treatment for schizophrenia.Methods:90 schizophrenic inpatients at the second affiliated hospital of Xinxiang Medical College from April 2019 to October 2020 were recruited and randomly assigned to a placebo group or the celecoxib adjunctive treatment group using a random number table. In the placebo group, 46 patients (29 males, 17 females; aged 21-34, mean age 27.46±6.50 years) completed a 6-week follow-up. In the celecoxib group, 44 patients (32 males, 12 females; aged 21-39, mean age 30.52±8.69 years) completed a 6-week follow-up. The Positive and Negative Syndrome Scale (PANSS) was used to assess psychiatric symptoms in both groups. Changes in PANSS score at the end of the treatment were compared to evaluate the efficacy of celecoxib. Metabolic indicators such as weight, body mass index, waist circumference and plasm glucolipid, as well as cardiovascular indicators like blood pressure, electrocardiogram and routine blood tests, and adverse events were collected for the safety evaluation. Serum tumor necrosis factor-α (TNF-α), Interleukin-4 (IL-4) and interferon-γ (IFN-γ) were also tested. Pearson correlation analysis was used to explore the relationship between cytokine levels, PANSS score, PANSS reduction rate [(pre-treatment score-post-treatment score)/pre-treatment score×100%], and the safety measurements in the two groups, analyzing the role of inflammation in celecoxib adjunctive therapy.Results:The change of PANSS positive score at the end of the 6th week was significantly higher in the celecoxib adjuvant treatment group than in the placebo group (-8.00±6.12 vs -4.78±5.19, H=-0.55, P=0.009). The weight changes, body mass index, total cholesterol, and triglycerides over 6 weeks were significantly lower in the celecoxib group compared to the placebo group ( F=-7.37, -7.30, 2.56, -2.54; all P<0.05). No serious adverse events were found in celecoxib adjuvant therapy. In the placebo group, baseline TNF-α levels were positively correlated with baseline negative symptoms and PANSS reduction rate ( r=0.260 and 0.330, both P<0.05), and negatively correlated with the 6-week weight ( r=-0.311, P<0.05); baseline IL-4 levels were positively correlated with the 6-week PANSS total score and the 6-week PANSS negative score ( r=0.320 and 0.397, both P<0.05), and negatively correlated with PANSS reduction rate and 6-week blood glucose ( r=-0.316 and -0.331, both P<0.05); Six-week IFN-γ levels were negatively correlated with low-density lipoprotein levels ( r=-0.306, P<0.05). And no such correlation was found in celecoxib adjuvant group. Conclusion:Celecoxib adjunctive therapy can improve positive symptoms of schizophrenia without causing adverse reactions. Inflammatory state is related to schizophrenia symptoms, treatment efficacy and metabolic abnormalities.

Objectives:To investigate the association between single nucleotide polymorphisms (SNP) of indoleamine 2,3-dioxygenase( IDO) genes and schizophrenia (SZ) in a Chinese Han population. Methods:Using a case-control study method, 3 700 in-patients with SZ were recruited from January 2010 to December 2021 at the Second Affiliated Hospital of Xinxiang Medical University, and 8 580 healthy controls were recruited from surrounding communities in Xinxiang City. The patient group and control group were matched in gender and age. After collecting peripheral blood from all subjects and extracting genomic DNA, the sample DNA was genotyped using methods such as gene chips and amplification refractory mutation system. The association analysis between IDO gene SNPs and SZ was conducted using the online analysis tool SHEsis. The differences in IDO gene SNP genotype and allele frequency between the two groups were compared using chi-square test. Linkage disequilibrium analysis, haplotype analysis, and Hardy Weinberg equilibrium test were performed using Haploview v4.2 software. A multifactor dimensionality reduction software was used to evaluate the interaction between SNPs and SNP frequencies. Results:In the four SNP loci of IDO gene, there was a significant difference in genotype and allele frequency between the SZ patient and the health control at rs9657182 locus (χ 2=11.81, P=0.003;χ 2=5.54, P=0.019). After Bonferroni correction, the genotype difference at rs9657182 locus still showed statistical significance ( P=0.011). There were no statistically significant differences in genotype and allele frequency among the three SNP locis (rs7820268, rs4503083, and rs10109853). Further stratified by gender, there was no significant difference in genotype frequency between the two groups at the rs9657182. Haplotype analysis revealed that the haplotype of CC and TC (rs9657182 and rs7820268) were significantly different between the two groups (χ 2=3.93,4.78, P=0.048, 0.029). Conclusion:The rs9657182 locus of IDO gene may be a susceptible locus for SZ. The haplotype of CC and TC may be associated with the onset of SZ.

Volume-regulated anion channels(VRACs)are present in vertebrate cells and a variety of tumor cells.VRACs include leucine-rich-repeat-containing 8A(LRRC8A)and its four homologous family members(LRRC8B-E),of which LRRC8A is an essential subunit.It has been confirmed that the VRAC LRRC8A is involved in the proliferation,migration,invasion,and multi-drug resistance of tumor cells through various signaling pathways.This ion transporter has shown good potential for use in strategies to kill tumor cells and prevent the development of tumors and can be used as a new target for tumor therapy.Therefore,this paper reviews the latest research on the involvement of LRRC8A in tumorigenesis and development.The molecular structure,function,and regulation of LRRC8A in tumor and immune cells,with emphasis on targeting LRRC8A in tumor diagnosis and immunotherapy,are discussed,providing a reference for studies exploring LRRC8A as a new tumor therapy target.

Necroptosis is a regulated process of programmed cell death independent of aspartic acid-specific cysteine protease,which can induce inflammation.Studies have shown that necroptosis is closely related to the progression and prognosis of pancreatic disease and plays an important two-way regulatory role in its progression.Related necroptosis inhibitors and inducers are expected to be used in the treatment of pancreatic disease.We herein review the mechanism of necroptosis and its role in the progression of pancreatic disease to provide a new understanding of the pathogenesis and treatment of pancreatic diseases and offer a theoretical basis for the research and development of targeted drugs.
