ObjectiveTo systematically quantify the multidimensional effect of virtual reality-based exergaming (VREG) on health outcomes among individuals with cognitive impairment under the framework of the International Classification of Functioning, Disability and Health (ICF). MethodsMeta-analysis was conducted in accordance with the PRISMA statement. PubMed, Cochrane Library, Embase, Scopus, Web of Science, CNKI, Wanfang Data and VIP were researched for randomized controlled trials (RCTs) investigating VREG for cognitive impairment, with the search deadline set on February 1, 2026. The Cochrane Risk of Bias 2.0 tool was adopted to evaluate the methodological quality of included studies. A three-level meta-analytic model was implemented with R 4.4.2. The GRADE framework was further used to rate the certainty of pooled evidence. ResultsA total of 22 RCTs were included. VREG might improve global cognitive function (SMD = 0.69, 95%CI 0.11 to 1.28, P = 0.022), memory (SMD = 0.47, 95%CI 0.07 to 0.87, P = 0.023), attention (SMD = 0.62, 95%CI 0.23 to 1.01, P = 0.004), executive function (SMD = 0.42, 95%CI 0.09 to 0.75, P = 0.013), balance (SMD = 0.54, 95%CI 0.07 to 1.00, P = 0.027), muscle strength (SMD = 0.63, 95%CI 0.37 to 0.88, P = 0.001), mobility (SMD = 0.29, 95%CI 0.04 to 0.54, P = 0.024) and quality of life (SMD = 0.29, 95%CI 0.03 to 0.56, P = 0.029). No significant effect was observed for depressive symptoms, comprehensive physical fitness and fall risk (all P > 0.05). Subgroup and meta-regression analyses indicated that session duration < 45 minutes produced the largest improvement in attention (SMD = 0.95, 95%CI 0.55 to 1.34, P < 0.001); intervention cycles of twelve to 24 weeks were optimal for mobility (SMD = 0.85, 95%CI 0.44 to 1.25, P < 0.001); age negatively correlated to balance improvement (β = -0.11, 95%CI -0.20 to -0.02, P = 0.020), suggesting less intervention benefits among older participants. ConclusionVREG is an effective non-pharmacological intervention to improve multidimensional physical and mental health in people with cognitive impairment. Protocols featuring short single sessions with long-term duration should be prioritized.

Objective To investigate the early predictive value of combined detection of serum sodium,heparin-binding protein-to-albumin ratio(HBP/ALB)and interleukin-10(IL-10)in Ka-wasaki disease shock syndrome(KDSS)caused by Kawasaki disease in children.Methods A total of 105 children with KDSS caused by Kawasaki disease(KDSS group)and 105 children with Kawasa-ki disease(control group)were selected as study subjects.Clinical data,serum sodium levels,HBP/ALB and IL-10 levels were compared between the two groups.Multivariate logistic regression a-nalysis was used to screen the influencing factors of KDSS caused by Kawasaki disease in children a-mong serum sodium,HBP/ALB and IL-10.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the predictive value of traditional prediction schemes(coronary artery dam-age and IVIG resistance)and new prediction schemes(serum sodium and HBP/ALB,IL-10)for KDSS caused by Kawasaki disease in children.Results The proportion of patients with coronary ar-tery damage and IVIG resistance was significantly higher in the KDSS group than those in the control group(P＜0.05).Serum sodium levels were lower,while HBP/ALB and IL-10 levels were higher in the KDSS group compared to the control group(P＜0.05).Multivariate logistic regression analysis showed that serum sodium,BP/ALB and IL-10 were influencing factors of KDSS caused by Kawasaki diseasein children(P＜0.05).For traditional prediction schemes,the areas under the curves(AUCs)for coronary artery damage,IVIG resistance and their combination in predicting KDSS caused by Kawasaki disease were 0.795,0.676 and 0.873,respectively(P＜0.05);for new prediction schemes,the AUCs for serum sodium,HBP/ALB,IL-10 and their combination in predicting KDSS were 0.767,0.824,0.760 and 0.945,respectively(P＜0.05).The AUC for the combination of serum sodium,HBP/ALB and IL-10 was greater than that for the combination of coronary artery dam-age and IVIG resistance(P＜0.05).Conclusion Decreased serum sodium,elevated HBP/ALB and elevated IL-10 are associated with KDSS caused by Kawasaki disease in children.Combined prediction using serum sodium,HBP/ALB and IL-10 has a high predictive value for KDSS caused by Kawasaki disease in children.

Personalized drug response prediction from molecular data is an important challenge in precision medicine for treating cancer.Computational methods have been widely explored and have become increasingly accurate in recent years.However,the clinical application of prediction methods is still in its infancy due to large discrepancies between preclinial models and patients.We present a novel disentangled synthesis transfer network(DiSyn)for drug response prediction specifically designed for transfer learning from preclinical models to clinical patients.DiSyn uses a domain separation network(DSN)to disentangle drug response related features,employs data synthesis technology to increase the sample size and iteratively trains for better feature disentanglement.DiSyn is pretrained on large-scale unlabeled cancer samples and validated by three datasets,The Cancer Genome Atlas(TCGA),Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging And moLecular Analysis 2(I-SPY2)and Novartis Institutes for Biomedical Research Patient-Derived Xenograft Encyclopedia(NIBR PDXE),achieving competitive performance with the state-of-the-art methods on cancer patients and mice.Furthermore,the application of DiSyn to thousands of breast cancer patients show the heterogeneity in drug responses and demonstrate its potential value in biomarker discovery and drug combination prediction.

Objective To explore the characteristics and influencing factors of complicated intra-abdominal infection in ICU patients after abdominal surgery.Methods A retrospective study was performed on ICU patients(n=92,observation group)developing complicated intra-abdominal infection after abdominal surgery versus patients(n=104,control group)without complicated intra-abdominal infection after abdominal surgery in our hospital from January 2020 to December 2023.The characteristics of patients who developed complicated intra-abdominal infections were analyzed and the relevant influencing factors were identified using multivariate Logistic regression analysis.Results A total of 124 strains of pathogenic bacteria were isolated and identified in 92 infected patients,with 64.52％(80/124)of Gram-negative strains comprising mainly 29.03％(36/124)of Escherichia coli,25.81％(32/124)of Gram-positive strains comprising mainly 12.90％(16/124)of Enterococcus faecalis,and 9.68％(12/124)of fungi comprising mainly 6.45％(8/124)of Candida albicans.Multivariate Logistic regression results showed that preoperative underlying disease,surgical methods,duration of surgery,invasive procedures,antibiotic use,and length of ICU stay,enteral nutrition were the influencing factors of complicated intra-abdominal infection in ICU patients after abdominal surgery(P＜0.0 5).Conclusion Patients with complicated intra-abdominal infection are infected with a variety of pathogenic bacteria,predominantly Gram-negative.The patient's preoperative underlying disease,surgical approach,duration of surgery,invasive procedures,use of antibiotics,length of ICU stay,and early enteral nutrition all affect the risk of complicated intra-abdominal infection in ICU patients after abdominal surgery.

Objective:To investigate the autophagy level of CD8+T cells in rat model of chronic obstructive pulmonary disease(COPD)and correlation with its number,and to explore the role of autophagy in pathogenesis of COPD.Methods:Thirty-six 6-week-old male SD rats were divided into three groups,including normal control group,COPD group and COPD intervention group.COPD model was established by smoking,and intraperitoneal injection of 3-methyladenine(3-MA)was used for intervention.Lung function of rats was detected by small animal pulmonary function testing,and frequency of CD8+T cells,CD8+memory T cells,CD8+effector T cells in blood and lung of rats were detected by flow cytometry.CD8+T cells were sorted by immunomagnetic beads,and expressions of autophagy protein including LC3-Ⅱ/Ⅰ,Beclin-1 and p62 in CD8+T cells were detected by Western blot.The middle lobe of right lung was collected for histological observation.Results:Infiltration of inflammatory cells and the decline of lung function in COPD group were more obvious than those in normal group.Frequency of CD8+T cells,CD8+effector T cells and CD8+memory T cells in blood and lung of rats in COPD group were significantly higher than those in normal control group(all P<0.05).Level of autophagy protein,LC3-Ⅱ/Ⅰ and Beclin-1 of CD8+T cells in COPD group were significantly higher than that in normal control group,while level of p62 was lower than that in normal control group(P<0.01).CD8+T cells,CD8+effector T cells,CD8+memory T cells in COPD intervention group were significantly lower than those in COPD group(P<0.05).Correlation analysis showed that LC3-Ⅱ/Ⅰ expression level was positively correlated with frequency of CD8+T cells in blood(r=0.667,P<0.01).Expression level of Beclin-1 was positively correlated with frequency of CD8+T cells and CD8+effector T cells in blood(r=0.505,P=0.021;r=0.428,P=0.037).Expression of LC3-Ⅱ/Ⅰprotein was positively correlated with frequency of CD8+T cells and CD8+effector T cells in lung tissue(r=0.474,P=0.019;r=0.549,P=0.006).Expression of Beclin-1 was positively correlated with frequency of CD8+effector T cells in lung tissue(r=0.458,P=0.025).Conclusion:Level of CD8+T cell autophagy is correlated with its number.CD8+T cell autophagy may be involved in the chronic inflam-matory process of COPD,and 3-MA can inhibit COPD inflammation.

Objective:To analyze the association of apolipoprotein E(ApoE),soluble semaphoring 4D(sSema4D),and cyclophilin A(CypA)levels with unfavorable outcome in patients with chronic heart failure(CHF).Methods:We retrospectively enrolled 108 patients with CHF admitted in the Fifth Affiliated Hospital of Zhengzhou Universi-ty between March 2019 and March 2022.According to the outcome during 6-month follow-up,patients were di-vided into favorable outcome group(n=71)and unfavorable outcome group(n=37).ApoE,sSema4D and CypA levels were compared between the two groups,and multivariate Logistic regression was employed to identify the risk factors of unfavorable outcome within 6-month follow-up in CHF patients.Results:Compared to patients in the favorable outcome group,those in the unfavorable outcome group had significant higher proportion of NYHA classⅣ(59.46％vs.25.35％),serum creatinine[(80.74±3.89)μmol/L vs.(71.36±3.63)μmol/L],ApoE[(69.87±4.25)mg/L vs.(47.36±3.17)mg/L],sSema4D[(916.62±7.32)ng/L vs.(426.42±6.25)ng/L]and CypA[(6.74±1.32)ng/L vs.(4.38±0.72)ng/L](P＜0.001 all).Multivariate Logistic regression indicated that NY-HA class Ⅳ(OR=2.782,95％CI 1.166～6.636),serum creatinine(OR=29.893,95％CI 6.782～131.768),ApoE(OR=12.046,95％CI 4.694～30.913),sSema4D(OR=8.390,95％CI 2.260～31.146)and CypA(OR=6.486,95％CI 1.780～23.635)were independent risk factors for unfavorable outcome within 6-month follow-up in CHF patients(P＜0.05 or＜0.01).Conclusion:The levels of ApoE,sSema4D and CypA were closely associated with short-term unfavorable outcome in patients with chronic heart failure.

AIM To investigate the ameliorative effects of Compound Fufangteng Mixture(CFM)on cyclophosphamide(CTX)-induced immunosuppression in mice.METHODS Forty-eight male C57BL/6J mice were randomly divided into the blank control group,the model group,the levamisole hydrochloride group(40 mg/kg)and the low-dose,medium-dose and high-dose CFM groups(3.75,7.5,10 g/kg),with 8 mice in each group,and given respective intervention orally once daily for 14 days.On the 5th to 7th day of administration,with the blank control group given normal saline intraperitoneally,the other groups underwent intraperitoneal CTX injections(80 mg/kg).24 hours after the last administration,organ indices of thymus and spleen were calculated;splenic histopathological alterations were assessed by HE staining;serum levels of IL-2,IL-6 and IgG were quantified using ELISA;splenic CD4+,CD8+T lymphocytes,alongside CD86+and CD206+macrophages populations were analyzed by flow cytometry;and splenic expression of CD4,CD8 and F4/80 was evaluated by immunohistochemical staining.RESULTS In CTX-treated mice,CFM administration mitigated body weight loss;enhanced thymus weight and thymic index;ameliorated splenic immune cell populations,elevated serum levels of cytokines IL-2,IL-6 and IgG in serum;and upregulated splenic levels of CD45+CD3+T lymphocytes and F4/80+CD11b+macrophages,alongside increasing the expression of CD4,CD8 and F4/80 surface markers.CONCLUSION CFM alleviates CTX-induced immunosuppression state in mice by modulating immune cells,restoring immune function and enhancing anti-inflammatory and tissue repair capabilities.

AIM To investigate the protective effects of kaempferide on hyperuricemic nephropathy(HN)in mice.METHODS Sixty Kunming mice were randomly divided into the control group,the model group,the allopurinol group(5 mg/kg),the kaempferol group(50 mg/kg),and the low-dose and high-dose kaempferide groups(25,50 mg/kg).HN mouse models were established by administering potassium oxyzinate(300 mg/kg)and hypoxanthine(500 mg/kg)in combination for 21 days,concurrently with the test drug.Following treatment administration,serum uric acid(SUA),serum creatinine(SCr),24-hour urinary protein(24 h UTP),and hepatic xanthine oxidase(XOD)levels were measured.Renal tissue pathology was assessed using HE staining and Masson staining.Apoptosis in renal tissue was evaluated via TUNEL staining.The expressions of NLRP3 inflammasome and apoptosis-associated proteins in renal tissues were analyzed by immunohistochemistry and Western blot.RESULTS Compared to the control group,the model group demonstrated elevated levels of SUA,SCr,24 h UTP,and hepatic XOD activity(P＜0.01);marked renal damage,and increased area of renal interstitial fibrosis and apoptosis rate(P＜0.01);and increased protein expressions of NLRP3,ASC,Caspase-1,cleaved-Caspase-1,pro-IL-1β,IL-1β,Caspase-3 and cleaved-Caspase-3 in renal tissue(P＜0.05,P＜0.01).Compared to the model group,the groups treated with allopurinol,kaempferol,or kaempferid showed reduced levels of SUA,SCr,24 h UTP,and hepatic XOD activity(P＜0.05,P＜0.01);improved renal pathological injury with reduced renal interstitial fibrosis area and apoptosis rate of renal tissue(P＜0.01);and downregulated protein expressions ofNLRP3,ASC,Caspase-1,cleaved-Caspase-1,pro-IL-1β,IL-1β,Caspase-3 and cleaved-Caspase-3 in renal tissue as well(P＜0.05,P＜0.01).CONCLUSION Kaempferide improves renal function while attenuating inflammation,fibrosis,and apoptosis in the kidneys of HN mice.This nephroprotective effect may stem from its dual action in inhibiting hepatic XOD to reduce uric acid synthesis and blocking NLRP3 inflammasome activation.

Purpose To quantitatively compare the diffusion parameters of mono-and biexponential diffusion-weighted imaging models,and to obtain optimal sets of b-values in diffusion-weighted MRI for obtaining monoexponential apparent diffusion coefficient(ADC)close to perfusion-insensitive intravoxel incoherent motion(IVIM)model ADC(ADCIVIM)in identifying of pulmonary solid benign and malignant lesions.Materials and Methods IVIM was performed in 40 patients with solid nodule and masse in Xi'an Gaoxin Hospital from July 2021 to August 2022 using a 3.0T MR imager.Two experienced diagnostic radiologists subjectively evaluated the IVIM images.A single index model was used to calculate ADC values(ADC0-1 000,ADC20-1 000,ADC50-1 000,ADC80-1 000,ADC150-1 000,ADC300-1 000,ADC500-1 000,ADC300,500,1 000,ADC300,800,1 000,ADC300,500,ADC300,800 and ADC300,1 000).The reference standard ADCIVIM value were calculated using a double-exponential model.The physician's measurements between two physicians were measured.The malignant and benign groups were compared and receiver operator characteristic curve for all parameters were analyzed.Results The measurement consistency of ADC values under b value sets and ADCIVIM was very good,and the intraclass correlation coefficient was more significant than 0.75.The differences between ADCIVIM and ADC values in each b group were statistically significant(t=-6.016--2.500,all P<0.05).The area under the curve(AUC)of ADCIVIM was the largest(0.906),with an optimal threshold of 1.271×10-3 mm2/s,a sensitivity of 80.0%and a specificity of 93.0%.The diagnostic efficacy close to ADCIVIM were ADC300,800(AUC=0.891),ADC50-1 000(AUC=0.827)and ADC300,800,1 000(AUC=0.795),respectively.The optimal threshold of ADC300,800 was 1.140×10-3 mm2/s,the sensitivity and specificity were 80.0%and 93.7%,respectively.Conclusion Combining b-values 300 s/mm2 and 800 s/mm2 is recommended as routine scanning parameters for identifying the insensitive monoexponential ADC between benign and malignant solid pulmonary lesions.
