Objective To explore the relationship between translocase of outer mitochondrial membrane 40（TOMM40）gene polymorphism and inflammatory status and cognitive function in patients with vascular dementia（VaD）. Methods From June 2020 to December 2022，48 patients with VaD and 40 age-matched control participants were enrolled. TOMM40_rs11556505 and IL-10-592 A/C_rs1800872 polymorphisms were measured. The cognitive function of the patients was evaluated by using the Repeatable Battery for the Assessment of Neuropsychological Status（RBANS）. Results The main effects of VaD were significant in all the analyses of the sub-scores and total score of RBANS（all P<0.001，all FDR<0.001）. TOMM40_rs11556505 polymorphism had a significant main effect on language score（F=4.524，P=0.034，Cohen f=0.08）. TOMM40×VaD had significant interaction effects on immediate memory（F=4.682，P=0.031，Cohen f=0.08）and language score（F=4.465，P=0.035，Cohen f=0.08）. The two-way multivariate analysis of covariance（IL-10×TOMM40）revealed significant interaction effects between their gene polymorphisms on visual space/structure（F=4.063，P=0.045，FDR=0.080，Cohen f=0.13），language（F=12.031，P<0.001，FDR=0.006，Cohen f=0.23），and delayed memory（F=5.118，P=0.025，FDR=0.075，Cohen f=0.23）in patients with VaD. Conclusion IL-10-592 A/C and TOMM40_rs11556505 gene polymorphisms have interaction effects on cognitive function，with their influence direction depending on each other's genotype.

Cuproptosis, a recently discovered form of regulated cell death involving copper ion metabolism, has emerged as a promising approach for tumor therapy. This pathway not only directly eliminates tumor cells but also promotes immunogenic cell death (ICD), reshaping the tumor microenvironment (TME) and initiating robust anti-tumor immune responses. However, translating cuproptosis-based therapies into clinical applications is hindered by challenges, including complex metabolic regulation, TME heterogeneity, and the precision required for effective drug delivery. To address these limitations, nanoparticles offer transformative solutions by providing precise delivery of cuproptosis-inducing agents, controlled drug release, and enhanced therapeutic efficacy through simultaneous modulation of metabolic pathways and immune responses. This review systematically discusses recent advancements in nanoparticle-based cuproptosis delivery systems, highlighting nanoparticle design principles and their synergistic effects when integrated with other therapeutic modalities such as ICB, PTT, and CDT. Furthermore, we explore the potential of cuproptosis-based nanomedicine for personalized cancer treatment by emphasizing strategies for TME stratification and therapeutic optimization tailored to patient profiles. By integrating current insights from metabolic reprogramming, tumor immunotherapy, and nanotechnology, this review aims to facilitate the clinical translation of cuproptosis nanomedicine and significantly contribute to the advancement of precision oncology.

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.

Cholesterol,as an important component of cell membranes,plays a multifaceted role in mediating tumor immunomodulation and drug intervention.In case of cholesterol metabolic imbalance,the accumulation of cholesterol metabolic intermediates,the changes in concentrations,and the regulation of related signaling pathways can affect tumor immunity by promoting inflammation and inhibiting immune cell function.Preclinical and clinical studies have shown that controlling cholesterol metabolism can inhibit tumor growth,re-shape body immune regulation,and enhance antitumor immunity.A deep understanding of the association between immune cells and cholesterol metabolic pathways in the tumor microenvironment can help to develop novel drugs targeting cholesterol metabolism.This article reviews the multifaceted role of cholesterol and its derived metabolites in the tumor microenvironment by regulating various types of immune cells such as myeloid-derived suppressor cells,tumor-associated macrophages,dendritic cells,and T-lymphocytes,as well as the characteristics of tumor immunomodulation mediated by cholesterol metabolism and the advances in pharmaceutical re-search on improving the immune function of the body by intervening against cholesterol,in order to further provide new ideas and a thera-peutic basis for cholesterol modulation and intervention in tumor im-munotherapy.

Objective To evaluate the causal relationship between serum uric acid(SUA)level and cerebrovascular disease(CVD)by a two-sample bidirectional Mendelian randomization(MR)study.Methods Single nucleotide polymorphisms(SNPs)from Genome-Wide Association Studies(GWAS)were obtained as instrumental variables for both samples.Inverse-variance weighted(IVW)method was primarily adopted,with weighted median method,weighted mode method,and MR-Egger regression serving as supplementary approaches for sensitivity analyses to verify the robust-ness of the results.Results The forward IVW analysis results showed that increased SUA was a risk factor for stroke(OR=1.183,95％CI,1.081 to 1.295,P=2.51× 10-4),ischemic stroke(OR=1.196,95％CI,1.084 to 1.320,P=3.81 ×10-4),and large artery atherosclerotic stroke(OR=1.466,95％CI,1.134 to 1.897,P=0.004),and also a protective factor for vascular dementia(OR=0.451,95％CI,0.273 to 0.745,P=0.002)and multi-infarct dementia(OR=0.372,95％CI,0.144 to 0.959,P=0.041).The reverse IVW analysis results did not support a causal effect of genetically predicted CVD risk on SUA level.All significant results were corrected by Bonfer-roni with P value less than 0.005.Sensitivity analyses further confirmed the reliability of the study find-ings.Conclusion The MR analysis reveals positive correlations between increased SUA level and the risk of stroke,ischemic stroke and large artery atherosclerotic stroke,and negative correlations of SUA level with the risk of vascular dementia and multi-infarct dementia.

Spontaneous coronary artery dissection is a non-atherosclerotic cause of acute coronary syndrome, particularly among young women. A 46-year-old female without a family history of cardiac disease and traditional atherosclerotic risk factors presented to hospital with non-ST-segment elevation myocardial infarction. Diagnostic coronary angiography revealed moderate stenosis of the left main coronary artery and the left anterior descending artery with blood flow thrombolysis in myocardial infarction grade 3. The left circumflex artery was observed hypoplastic without significant stenosis. Intravascular ultrasound revealed an extensive intramural hematoma from the middle of the left anterior descending branch to the left main trunk and a compressed lumen with intact intima. The patient underwent conservative treatment and remained asymptomatic 11 months after discharge. Repeat coronary computed tomography angiography showed haematoma absorption with stenosis relief. Spontaneous coronary artery dissection of the left main coronary artery is relatively rare. Its management is based on the patient’s clinical condition and lesion characteristics.

Objective To investigate the effect of acupuncture at Hegu(LI4)on neural activity in the visual cortex of healthy volunteers using functional near-infrared spectroscopy(fNIRS).Methods Each healthy volunteer underwent three sets of trials in a resting state:the LI4 group received acupuncture stimulation at the right Hegu(LI4)acupoint;the negative control was the sham acupoint group(SHAM group);and the positive control was the visual stimulation group(VISUAL group).fNIRS was used to simultaneously monitor changes in oxygenated hemoglobin(Oxy-Hb)levels in the vis-ual cortex during various stages of acupuncture or visual tasks,thereby reflecting the activation level of the visual cortex.The entire acupuncture procedure was performed with the subjects' eyes closed.fNIRS recorded the raw optical density values of hemodynamics in the region of interest(ROI)of the visual cortex during each task phase.The relative coefficientβ value for oxygenated hemoglobin was obtained via Matlab analysis,and the coefficient difference Δβ value between the task period and the baseline period was calculated,representing the degree of change in oxygenated hemoglobin content in-duced by the stimulus,which reflected the change in activation level of the visual cortex after acupuncture or visual stimu-lation.A larger Δβ value indicates a higher degree of visual cortex activation.Generalized estimating equations(GEE)were applied to analyze the differences in visual cortex activation levels among the LI4,SHAM,and VISUAL groups.Results In channels 15 and 17 of the striate area and channels 10 and 13 of the extrastriate area,the Δβ values of sub-jects in the LI4 group during the needle manipulation and withdrawal phases were significantly higher than those in the SHAM group(all P＜0.01).When comparing the Δβ values of the LI4 group during the needle manipulation and withdrawal phases with those of the VISUAL group,under the current sample size,the differences were not statistically significant(all P＞0.05).The Δβ values in both the striate and extrastriate areas of the LI4 group peaked during the needle manipulation phase.Conclusion Acupuncture at Hegu(LI4)can effectively activate the visual cortex in healthy volunteers,with the most significant increase in activation observed during the needle manipulation phase.
