Despite breakthroughs in immunotherapy for solid tumors, significant variations in treatment efficacy persist. Up to 80% of cancer patients suffer from malnutrition, which leads to: lymphoid atrophy and reduced T-cell reserves; deficiency of substrates required for T-cell activation and expansion; concurrent inflammation hindering T-cell infiltration into tumors; and cachexia accelerating PD-1 antibody clearance. Clinical studies confirm that severe malnutrition significantly impairs immune responses and increases the risk of treatment toxicity. Therefore, implementing standardized nutritional therapy is crucial for optimizing the reserve, activation, expansion, and infiltration capacity of immune cells, thereby providing a sound immune system foundation for immunotherapy. Immunonutrition therapy, by enhancing immunonutrients such as arginine, omega-3 polyunsaturated fatty acids, and nucleotides, reduces the secretion of pro-inflammatory mediators and promotes T-cell activation and proliferation. This enhances anti-tumor immune responses, prolongs survival, and advances cancer treatment towards multimodal combination and precision approaches.

Objective To explore the non-invasive diagnostic criteria of magnetocardiography (MCG) for coronary microvascular dysfunction (CMVD), and its value in dynamically assessing drug treatment for CMVD. Methods Patients who presented with chest tightness or chest pain at Zhongshan Hospital, Fudan University from September 2024 to March 2025 were consecutively enrolled, and all of whom had non-obstructive coronary arteries on angiography. Using the coronary angiography-derived index of microcirculatory resistance (caIMR) as the gold standard, patients were divided into a normal microcirculation group (caIMR≤40 U) and a CMVD group (caIMR＞40 U). MCG testing was performed using a domestic device (MD-U041001, Mind Medical). Patients in the CMVD group received adenosine treatment and underwent repeat MCG after medication. Differences in MCG parameters between the two groups were analyzed, and a diagnostic model was established. The value of the diagnostic model was analyzed using receiver operating characteristic (ROC) curves. Results A total of 311 patients were included, with 135 in the normal microcirculation group and 176 in the CMVD group. The CMVD group had a significantly higher proportion of males (61.9% vs 47.4%, P＝0.012), and lower high-density lipoprotein cholesterol (HDL-C) levels ([1.16±0.31] mmol/L vs [1.24±0.29] mmol/L, P＝0.029) than the normal group. Eleven MCG parameters showed significant differences between the two groups (P＜0.05), among which increased values of mfm_QR_epav, mfm_RS_epmse, space_zeroRTrot, as well as decreased value of mfm_QR_v1 were independent predictors of CMVD. The diagnostic model based on these 11 MCG parameters yielded an area under the curve (AUC) of 0.688 (95%CI 0.629-0.747). The integrated diagnostic model combining clinical risk factors (male, smoking history, HDL-C) with MCG parameters had an AUC of 0.701 (95%CI 0.643-0.759). After adenosine treatment, patients in the CMVD group showed significant decreases in mfm_QR_epav (P＝0.010), mfm_RS_sad (P＝0.013), and mfm_RS_epmse (P＝0.046). Conclusions The model based on MCG parameters demonstrates good diagnostic ability for CMVD; dynamic changes in MCG parameters following adenosine intervention may serve as potential objective indicators for evaluating microcirculatory treatment efficacy.

N7-methylguanosine(m7G)modification occurs at the 5'cap of mRNA in eukaryotes,and is also found at specific sites on tRNA and rRNA,showing wide conservation across various biological organisms.Aberrant m7G modification is involved in the dysregulation of gene expression and serves as a biomarker for multiple cancers,with significant potential for applications in tumor diagnosis and therapy.This review summarizes the biological functions and regulatory mechanisms of m7G modification,and outlines its potential clinical applications.It also highlights the oncogenic roles of aberrant m7G modification and its association with prognosis,providing a detailed discussion of the role and molecular mechanisms of abnormal m7G modification in regulating drug resistance in various cancers.

Depression is a highly heterogeneous psychiatric disorder with complex pathogenesis influenced by the interplay of biological,psychological,and social-environmental factors.Based on the 2021 edition of the Chinese Guidelines for the Prevention and Treatment of Depressive Disorders,which explicitly identify gender as a significant risk factor for depression onset,this paper systematically reviews the gender-differentiated pathogenesis and therapeutic advances in depression from both traditional Chinese medicine(TCM)and Western medical perspectives.In Western medicine,a large number of studies have demonstrated the sex-specific mechanism of estrogen/testosterone fluctuations and monoamine transmitter system regulation.While in TCM,although the constitution theory proposes that there are significant gender differences in congenital constitution and that qi depression and qi deficiency are associated with susceptibility to depression,current evidence primarily relies on cross-sectional surveys and lacks validation through high-quality RCTs.Compared with Western medicine,the direct research on gender-differentiated antidepressant effects in TCM remains relatively underdeveloped.In future study,it may be possible to deepen and improve the research on anti-depression in TCM from the biological markers of particular constitutions in the gender dimension.This paper advocates establishing a bio-psycho-social integrated intervention model,advancing mechanistic exploration through prospective cohort studies and multi-omics technologies,and promoting precision diagnosis and treatment systems based on gender differences,and to form a three-dimensional diagnosis and treatment and research system that covers biomarkers,social role assessment,and TCM constitution identification,in order to provide a new theoretical framework and a practical pathway for the precise medical treatment of depression.

Objective To observe the effects of four different modeling method on the hypothalamus-pituitary-adrenal(HPA)axis,blood rheology,platelet aggregation rate,and myocardial ischemia in rats,and to provide new ideas for the establishment of a rat model of"double heart"disease in line with clinical diagnosis and treatment characteristics.Methods Sixty-nine male Sprague-Dawley rats were divided randomly into a Control group(unstimulated),chronic unpredictable mild stimulation(CUMS)group,isoproterenol(ISO)group(intraperitoneal injection of ISO),high-fat diet(HFD)group(fed high-fat chow),and composite model(CUMS+ISO+HFD)group(n=12 rats in the Control and HFD groups;n=15 rats in the other three groups,respectively).Modeling procedures were carried out for a total of 8 weeks,with ISO injection started from week 6 of the experiment for a total of 3 weeks.At the end of modeling,rats in each group were subjected to absent-field and sugar-water preference behavioral tests.Electrocardiography(ECG)was performed to observe changes in ECG lead Ⅱ in each group.Serum levels of adrenocorticotropic hormone(ACTH),cortisol(Cor),corticosterone(CORT),endothelin-1(ET-1),and soluble intercellular adhesion molecule-1(sICAM-1)were detected by enzyme-linked immunosorbent assay.Myocardial histopathological changes were detected by hematoxylin/eosin(HE)staining.Serum total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were measured using an enzyme labeling instrument.Whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were assessed using an automatic blood rheology analyzer.The maximum platelet aggregation rate(MAR)and average platelet aggregation rate(AAR)induced by arachidonic acid and adenosine diphosphate were detected using a whole-blood platelet aggregometer.Results Compared with the Control group,all four model groups had significantly lower absenteeism distance and number of entries into the central region in the absent-field test,and a lower sugar-water preference ratio(P＜0.01).ECG revealed ST-segment elevation in the ISO and CUMS+ISO+HFD groups,tachycardia in the CUMS group,and mild ST-segment elevation in the HFD.Serum ACTH,Cor,CORT,ET-1,and sICAM-1 were all significantly elevated in the four model groups(P＜0.01).HE staining showed that myocardial tissue was severely damaged in rats in the ISO and CUMS+ISO+HFD groups,with pathological changes such as localized fibrosis and inflammatory infiltration of the myocardium,while mild cardiomyocyte disarrangement and fracture was seen in the CUMS and HFD groups.Rats in the HFD group had increased serum TC and LDL(P＜0.01)and decreased HDL contents(P＜0.01).Compared with the Control group,whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were all increased in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01,P＜0.05),while whole blood high-cut viscosity(200 V/S),whole blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen levels were decreased in rats in the ISO group(P＜0.01,P＜0.05).MAR and AAR were significantly higher in rats in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01),while the platelet aggregation rate was decreased in the ISO group compared with the Control group(P＜0.01,P＜0.05).Conclusions These result showed that the rat CUMS+ISO+HFD model better reflected the complexity of clinical double heart disease than the other three models.

Renal cancer is a common and increasingly prevalent malignancy with a complex pathogenesis influenced by genetics,smoking,and obesity.Current treatment mainly involves surgery with adjunctive chemotherapy,radiation,and immunotherapy,but high rates of recurrence and metastasis indicate its limited effectiveness,emphasizing the need for better therapeutic targets.Growing evidence indicates that epigenetic modifications,particularly RNA modifications,play a critical role in renal cancer development and progression.This review highlights recent advances in renal cancer epigenetics,focusing on RNA modifications such as N6-methyladenosine(m6 A),N7-methylguanosine(m7G),5-methylcytosine(m5C),N1-methyladenosine(m1A),adenosine-to-inosine(A-to-I),N6,2'-O-dimethyladenosine(m6Am),and N4-acetylcytidine(ac4C),along with their regulatory factors.It also explores the diagnostic and therapeutic potential of targeting RNA modifications and associated proteins.

Objective:To organize and interpret the hot topics and development trends in the field of military medical education research over the past decade with the assistance of visualization software, and provide direction and reference for further study.Methods:Visualization software was used to retrieve relevant literature published worldwide from 2014 to 2023. A visualization analysis was performed on annual publication volume, authors, institutions, and keyword clustering.Results:The numbers of domestic and foreign articles were 452 and 121, respectively. Domestic research reached a peak in 2014 and increased again in 2019 and 2020. Foreign research remained stable from 2014 to 2018 and increased significantly in 2019 and 2020. There were 28 domestic authors and 5 foreign authors who published more than two papers. Domestic research was primarily led by Naval Medical University (47 papers) and Air Force Medical University (21 papers). Internationally, the United States (10 institutions) and Israel (2 institutions) were at the forefront of research in this field. Keyword cluster and label analysis identified 11 cluster labels for domestic research, revealing research hotspots such as curriculum content reform in military medical universities, ideological and political education, practical training for general military doctors, and the improvement of military-civilian integrated medical service capabilities. Foreign research yielded 10 cluster labels, highlighting research hotspots such as emergency medical simulation training, health care, and psychological therapy intervention. Nine burst keywords were identified in both domestic and foreign literatures, indicating a recent domestic focus on job competency and a foreign emphasis on psychological impacts.Conclusions:Over the past decade, domestic research primarily focused on military medical school education reform and grassroots military medical officer education. In the last three years, the emphasis shifted towards the post competency of military medical staff. In contrast, international research centered on public health emergency medicine and health service management, with a shift in the past three years toward addressing both physiological and psychological issues.
