Objective: This study compared the effects of personalized exercise versus acupuncture on multidimensional cognitive function in individuals at high risk for stroke with mild cognitive impairment (MCI). Methods: A randomized controlled trial enrolled 200 stroke-risk adults aged 50−80 years. Ninety participants diagnosed with MCI (MMSE, HIS, CDR criteria) were randomly assigned to exercise (n = 30), acupuncture (n = 30), or control (n = 30) groups. Interventions lasted 6 months. Cognitive outcomes (MMSE, Raven’s Progressive Matrices, Digit Symbol Substitution Test, Animal Fluency, Rey-Osterrieth test, Stroop test) were assessed before and after intervention. Multivariate regression identified risk factors for MCI. ANOVA was used for group comparisons. Results: Hypertension (aOR = 1.5) and diabetes (aOR = 1.3) were significant risk factors for MCI. After intervention, the exercise group showed the largest MMSE improvement (Δ = 5.0), compared with acupuncture (Δ = 3.0) and control (Δ = 1.0) (p < 0.001). Exercise produced greater gains in non-verbal reasoning (31.8% vs. 26.1% in acupuncture, p < 0.01). Acupuncture more effectively enhanced processing speed and attention (DSST: Δ = 26 vs. Δ = 20 in exercise, p = 0.03) and executive function (Stroop interference time: Δ = 16 vs. Δ = 15 seconds in exercise, p = 0.04). Both interventions significantly improved verbal fluency (p < 0.001), with larger benefits in those with baseline MMSE ≤ 20. Conclusion Hypertension and diabetes are key risk factors for MCI in stroke-prone individuals. Exercise yields greater improvement in global cognition and memory, whereas acupuncture is more effective for enhancing attention and executive function. Both modalities benefit verbal fluency, particularly in lower-functioning participants.

Objective:To construct a model of mitochondria-related genes (Mito-RGs) in hepatocellular carcinoma (HCC), and predict the immune, prognostic and therapeutic characteristics of HCC based on the model, so as to provide a new idea for the diagnosis and treatment of HCC.Methods:The expression profiles of HCC and corresponding clinical information were obtained from the Cancer Genome Atlas (TCGA) database. Univariate Cox regression, Least Absolute Shrinkage and Selection Operator (LASSO) regression and multivariate Cox regression were used to construct a prognostic model of HCC based on Mito-RGs, and the International Cancer Genome Consortium-Liver Cancer-RIKEN-Japan ICGC-LIRI-JP dataset were used for validation. GO and KEGG analyses were performed to investigate the signaling pathways enriched for differentially expressed genes in the high- and low-risk groups. Immune infiltration was assessed using CIBERSORT. Single-cell data were used to study the proportion of immune cells in high- and low-risk groups of HCC samples and the relationship with cell proliferation. Cellminer was used to assess the relationship between risk score models and drug sensitivity.Results:A risk-prognostic model of HCC containing seven Mito-RGs ( DTYMK, ACADS, HMGCS2, CYP27A1, TOMM40L, STOM, and AKR1B10) was constructed. High-risk HCC patients had a worse prognosis. Genes upregulated in the high- and low-risk groups of differentially expressed genes were enriched in cell cycle and metabolism-related pathways. Single-cell data showed higher proportions of CD8 + T cells, macrophages and monocytes, and proliferating cells in the high-risk group. CIBERSORT analysis suggested that Treg cells and M0 macrophages were more abundant in the high-risk group, whereas CD8 + T cells and CD4 + memory T cells were less abundant. Patients in the high-risk group were more sensitive to myeloid cell leukemia sequence 1 inhibitor, vincristine, phosphatidylinositol kinase beta subunit inhibitor, and aurora kinase A, while trametinib, selumetinib, extracellular regulated protein kinase, and mitogen-activated extracellular signal-regulated kinase were more effective in the low-risk group. Conclusion:The constructed Mito-RGs model is capable of providing a more accurate assessment of the prognosis and the degree of immune cell infiltration in HCC patients.

Allergen specific immunotherapy（AIT）, as an effective treatment for allergic rhinitis, asthma, and other allergic diseases, has received widespread attention in the field of health economic evaluation in recent years. This article reviews the current status and progress of economic research on AIT, mainly discussing the socioeconomic burden of allergic rhinitis, the results of health economic studies from different countries, and the primary methods used in health economic research on allergic rhinitis. Existing studies indicate that, although AIT involves high initial costs, it offers significant long-term economic benefits by reducing healthcare resource utilization, improving patient quality of life, and decreasing medication dependence. Moreover, reducing initial costs, applying standardized assessment tools, and conducting cross-national comparative analyses have become key directions for future research. Overall, AIT demonstrates strong potential in terms of long-term health benefits and cost savings, providing solid economic evidence for the management of allergic diseases.

Objective:To investigate the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage in Chinese population from childhood to middle age.Methods:This study is a population-based, long-term follow-up cohort study. Participants who had their blood pressure measured at least 5 times in the Hanzhong Adolescent hypertension cohort from 1987 to 2023 were included in this study. Group-based trajectory modeling was used to identify different systolic and diastolic blood pressure trajectories, and the subjects were divided into low-increasing group, moderate-increasing group and high-increasing group according to blood pressure trajectories. Blood pressure variability was assessed using standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV). Target organ damage was evaluated during the final follow-up in 2023 (middle age). Logistic regression models were used to analyze the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage.Results:A total of 2 447 subjects were included, with a median age of 48 years, of whom 1 373 were male (56.1%). Based on systolic blood pressure, 868 were in the low-increasing group, 1 238 in the moderate-increasing group, and 341 in the high-increasing group. For diastolic blood pressure, the distribution was 894, 1 263 and 290, respectively. Compared with the low-increasing group of systolic blood pressure, the moderate-increasing group (arteriosclerosis: OR=4.14, 95% CI 2.96-5.79; proteinuria: OR=2.06, 95% CI 1.38-3.07; left ventricular hypertrophy: OR=1.68, 95% CI 1.00-2.82) and high-increasing group (arterial stiffness: OR=15.44, 95% CI 10.14-23.50; proteinuria: OR=5.80, 95% CI 3.63-9.29; left ventricular hypertrophy: OR=2.93, 95% CI 1.55-5.53) had a higher risk of target organ damage (all P<0.005). The moderate-increasing group of diastolic blood pressure had a higher incidence of arterial stiffness ( OR=3.72, 95% CI 2.69-5.12) and proteinuria ( OR=1.67, 95% CI 1.15-2.42) than the low-increasing group (all P<0.005), while the high-increasing group had a significantly higher risk of all type of target organ damage compared to the low-increasing group (arterial stiffness: OR=10.84, 95% CI 7.08-16.61; proteinuria: OR=3.72, 95% CI 2.31-5.99; left ventricular hypertrophy: OR=2.38, 95% CI 1.23-4.59; all P<0.005). Additionally, higher systolic blood pressure variability was associated with an increased incidence of arterial stiffness (SD: OR=2.25, 95% CI 1.96-2.57; VIM: OR=1.64, 95% CI 1.45-1.86; ARV: OR=1.70, 95% CI 1.50-1.93) and proteinuria (SD: OR=1.65, 95% CI 1.44-1.89; VIM: OR=1.41, 95% CI 1.22-1.63; ARV: OR=1.45, 95% CI 1.26-1.67; all P<0.005). The results for diastolic blood pressure variability indicators were similar to those for systolic blood pressure. Conclusion:Early-life blood pressure trajectories are predictive of target organ damage risk in middle age. Higher blood pressure variability is related to an increased risk of arterial stiffness and proteinuria, but was less associated with left ventricular hypertrophy. Focusing on the risk of high blood pressure early in life can help prevent the occurrence of target organ damage in middle age.

Objective:To explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

Objective To explore the impact of different moving patterns during the dip-coating process on thickness distributions of polymer heart valves.Methods Based on the volume of fluid(VOF)multiphase flow model,the Eulerian wall-film(EWF)model,and dynamic mesh technology,the dip-coating manufacturing process of polymer heart valves were numerically simulated.The effects of vertical,horizontal,and circular moving patterns on flow characteristics of the surface impregnation liquid and liquid film distributions under self-rotation conditions of the models were mainly studied.Subsequently,seven identical test points were set on each valve leaflet to collect thickness data,and the coefficient of variation(CV)was calculated to evaluate the uniformity of the liquid film thickness.Given that the vertical and horizontal patterns had fewer moving planes,limiting the optimization space,the circular pattern(45°)with richer moving planes was selected as the basis for optimization,and comparative analysis of numerical simulation was conducted.Results In the vertical pattern,the peak CV was 0.461 3;in the horizontal pattern,the CV was 0.060 8;and in the circular pattern,the CV at 30°,45° and 60° were 0.457 5,0.272 8,and 0.255 6,respectively.After optimization,the CV for the circular pattern(45°)decreased to 0.052 5,representing an 80.7％reduction compared to the pre-optimization value.Conclusions The moving patterns significantly affect the uniformity of dip-coating thickness distributions.The horizontal pattern demonstrates the best uniformity,while the vertical pattern shows the poorest uniformity.The CV for the circular pattern decreases as the angle increases,with its uniformity between that of the vertical and horizontal patterns.Optimization of moving pattern parameters based on simulation results has improved the uniformity of thickness distributions.

Extensive epigenetic reprogramming involves in memory CD8+ T-cell differentiation. The elaborate epigenetic rewiring underlying the heterogeneous functional states of CD8+ T cells remains hidden. Here, we profile single-cell chromatin accessibility and map enhancer-promoter interactomes to characterize the differentiation trajectory of memory CD8+ T cells. We reveal that under distinct epigenetic regulations, the early activated CD8+ T cells divergently originated for short-lived effector and memory precursor effector cells. We also uncover a defined epigenetic rewiring leading to the conversion from effector memory to central memory cells during memory formation. Additionally, we illustrate chromatin regulatory mechanisms underlying long-lasting versus transient transcription regulation during memory differentiation. Finally, we confirm the essential roles of Sox4 and Nrf2 in developing memory precursor effector and effector memory cells, respectively, and validate cell state-specific enhancers in regulating Il7r using CRISPR-Cas9. Our data pave the way for understanding the mechanism underlying epigenetic memory formation in CD8+ T-cell differentiation.

Objective To investigate the effect of aerobic exercise preconditioning on cardiac function in mice bearing subcutaneous transplantable tumors and explore the potential molecular mechanisms.Methods Twenty-four 6-week-old male BALB/c mice were selected.After an acclimation period,they were randomly assigned to a control group(C),a tumor group(M)and an exercise-preconditioning plus tumor group(EM),each of eight.The EM group underwent a 4-week aerobic exercise interven-tion.Meanwhile,the C group received 0.2 ml of physiological saline injected subcutaneously on the dorsum of the proximal left hind limb,while the M and EM groups were inoculated at the same site with 0.2 ml of a CT26.WT colon carcinoma cell suspension.Three weeks after inoculation,cardiac function was assessed by transthoracic echocardiography.Hearts were then harvested for hematoxylin-eo-sin staining to evaluate cardiomyocyte cross-sectional area(CSA),while Western blot was performed to determine the expression of proteins related to myocardial protein synthesis and degradation.Results(1)Compared with group C,group M exhibited significantly lower body weight and heart weight(P<0.05),and reduced left ventricular ejection fraction(LVEF),fractional shortening(FS)and stroke vol-ume(SV)(P<0.05),as well as cardiomyocyte CSA(P<0.01)and total mTOR(P<0.01),phosphory-lated mTOR(p-mTOR)(P<0.01)and the p-mTOR/mTOR ratio(P<0.05),but a significant increase in the expression of the muscle ring finger 1(MuRF-1)and the muscle atrophy F-box(MAFbx/Atrog-in-1)(P<0.01 and P<0.05,respectively).(2)Compared with group M,group EM showed significant-ly greater heart weight(P<0.05);increased left ventricular posterior wall thickness at end-diastole(LVPWd),LVEF,FS and SV(P<0.05),as well as the larger cardiomyocyte CSA and total mTOR,p-mTOR and the p-mTOR/mTOR ratio(P<0.05),but reduced MuRF-1 and Atrogin-1 expression(P<0.05).Conclusion Four weeks of aerobic exercise preconditioning ameliorated myocardial atrophy and improved systolic cardiac function in mice bearing subcutaneously transplanted CT26 tumors.Such beneficial effects may be associated with exercise-induced down regulation of the protein degradation mediators MuRF-1 and Atrogin-1 and up regulation of total mTOR and p-mTOR.

Salt plays a critical role in the development of hypertension,which is a major risk factor for damage to target organs such as the heart,brain,and kidneys.Salt sensitivity serves as the fundamental link between salt intake and hypertension.Considerable progress in research on salt-sensitive hypertension has been made regarding the pathogenesis,detection methods and genetic markers;the prevention and treatment of the disease are also constantly improving.Both salt intake and detection rate of salt-sensitive hypertension are relatively high in China.Therefore,exploring the pathogenesis and enhancing detection of salt-sensitive hypertension are crucial for the effective prevention and control of hypertension.

Objective To investigate the effects of aerobic exercise and different exercise habits on skeletal muscle function and the possible molecular mechanisms in colorectal cancer-loaded mice.Methods Thirty-five 5-week-old BABL/c male mice were acclimatized to feeding for 1 week and then divided randomly into the following groups:control(D),tumor(M),exercise preconditioning(QAM),lifetime exercise(AM),and exercise(HAM)groups(n=7 mice per group).Mice in the QAM and AM groups underwent aerobic exercise regimen 1 from weeks 2～6.At week 7,mice in the experimental groups received 0.2 mL of CT26 colon cancer cell suspension subcutaneously in the dorsal aspect of the left hind limb,while control mice received 0.2 mL of saline at the corresponding site.Mice in the AM and HAM groups were subjected to aerobic exercise regimen 2 for weeks 7～9.The general status and skeletal muscle mass and function were monitored in all mice throughout the experiments.After completion of the experiment,samples were collected and the cross-sectional area of gastrocnemius muscle fibers(CSA)was measured by hematoxylin and eosin staining and expression levels of proteins related to synthesis and catabolism of the gastrocnemius muscle were analyzed by Western Blot.Results(1)The weight ratio of the gastrocnemius muscle was significantly lower in mice in the M,QAM,and HAM groups compared with group D,and was significantly higher in AM mice compared with M,QAM,and HAM mice.(2)Grip strength,endurance,skeletal muscle circumference,and CSA were significantly lower in group D mice compared with the other groups,and was most enhanced in group HAM.Endurance and CSA were consistently enhanced in groups QAM,AM,and HAM.(3)Muscle RING-finger protein-1(MuRF1)expression levels were significantly lower in groups M,QAM,AM,and HAM than in group D,significantly lower in groups AM and HAM than in group M,and significantly lower in group HAM than in group QAM.(4)Fibronectin type Ⅲ domain-containing protein 5(FNDC5)expression levels were significantly lower in group M than in groups D and QAM.(5)Peroxisome proliferator-activated receptor gamma coactivator 1-alpha expression levels were significantly lower in the QAM and HAM groups compared with group M.(6)Expression levels of phospho(p)-AMP-activated protein kinase(AMPK)/AMPK and p-AMPK were significantly higher in group QAM than in groups D and M,p-AMPK expression significantly lower in groups AM and HAM was than in group QAM,and AMPK expression was significantly lower in groups QAM,AM,and HAM than in group D.Conclusions Exercise preconditioning and continuous aerobic exercise can improve skeletal muscle mass and function in CT26 colon cancer-loaded mice by activating AMPK phosphorylation to stimulate skeletal muscle secretion of FNDC5,thereby regulating the expression of MuRF1 protein.
