Objective To investigate the correlation between immune cells and the occurrence of cardiovascular disease(CVD)in patients with human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS),and to construct a risk prediction model.Methods A total of 280 HIV/AIDS patients treated from June 2024 to August 2025 were selected as the research subjects and divided into a training set(n=200)and a test set(n=80)at a ratio of 5:2.The patients in the training set were subdivided into a CVD subgroup(n=60)and a non-CVD subgroup(n=140)according to whether they developed CVD.The baseline characteristics and immune cells of the two groups were compared,and the longitudinal trajectory changes of immune cells in the CVD subgroup and the non-CVD subgroup were analyzed.LASSO regression analysis was used to screen the independent influencing factors of CVD,multivariate Logistic regression analysis was used to screen the independent risk factors for the occurrence of CVD,and a risk prediction nomogram model was constructed.The area under the receiver operating characteristic(ROC)curve(AUC),Hosmer-Lem show test,calibration curve,and decision curve were used to compare the risk prediction nomogram model with the general cardiovascular risk assessment model,to evaluate its discrimination,goodness-of-fit,and clinical utility.Results There were significant differences in the baseline characteristics and immune cells between the two groups(P<0.05).The longitudinal trajectory plots revealed that the CD4+count,CD8+count,and CD4+/CD8+level in the CVD group exhibited substantial fluctuations,while the trajectories of these parameters in the non-CVD group remained relatively stable.After LASSO regression analysis screened out 11 non-zero coefficient variables,multivariate logistic regression analysis showed that age,hypertension,total cholesterol,smoking,high-sensitivity C-reactive protein,CD4+count at the time of HIV diagnosis,CD8+count at the time of HIV diagnosis,and globulin were all independent influencing factors for the occurrence of CVD in HIV/AIDS patients(P<0.05).The AUC of the risk prediction nomogram model was 0.960 in the training set and 0.914 in the test set,indicating good discrimination of the model.The Hosmer-Lem show test and calibration curve showed good accuracy and consistency of the model,and the decision curve showed a high net benefit value,indicating good clinical utility.Conclusion The CVD risk in HIV/AIDS patients is jointly affected by immune dysfunction and traditional metabolic factors.The risk prediction nomogram model constructed significantly improves the accuracy of risk prediction of CVD and can provide a basis for early identification of high-risk patients and the formulation of individualized intervention strategies.

Objective To investigate the efficacy of nimodipine combined with donepezil in the treatment of CSVD patients with mild cognitive impairment.Methods A total of 130 CSVD pa-tients admitted to our department from October 2020 to October 2023 were recruited and ran-domly divided into monotherapy group(nimodipine,65 cases)and combined group(nimodipine plus donepezil,65 cases).The clinical efficacy after 3 months of treatment was recorded.The blood-brain barrier function and brain function indicators[serum neuron-specific enolase(NSE),vascular endothelial growth factor(VEGF),central nervous system specific protein(S100β)]were compared between the two groups.Results The clinical efficacy was significantly higher in the combined group than the monotherapy group(92.3％vs 78.5％,P＜0.05).The cerebrospinal fluid albumin and blood-brain barrier index were obviously increased in the two groups after treatment(P＜0.05),and the two indicators were notably lower in the combined group than the monothera-py group(P＜0.01).After treatment,the level of VEGF was remarkably elevated while those of NSE and S100β were marvelously reduced in the two groups when compared with the levels be-fore treatment(P＜0.05).The combined group obtained significantly higher VEGF level but low-er NSE and S100β levels than the monotherapy group after treatment(P＜0.01).Conclusion For CSVD patients with mild cognitive impairment,the combination of nimodipine and donepezil can effectively improve the cognitive impairment,and promote the brain function recovery.

Background::Although some well-established oncogenes are involved in cancer initiation and progression such as prostate cancer (PCa), the long tail of cancer genes remains to be defined. Goosecoid ( GSC) has been implicated in cancer development. However, the comprehensive biological role of GSC in pan-cancer, specifically in PCa, remains unexplored. The aim of this study was to investigate the role of GSC in PCa development. Methods::We performed a systematic bioinformatics exploration of GSC using datasets from The Cancer Genome Atlas, Genotype-Tissue Expression, Gene Expression Omnibus, German Cancer Research Center, and our in-house cohorts. First, we evaluated the expression of GSC and its association with patient prognosis, and identified GSC-relevant genetic alterations in cancers. Further, we focused on the clinical characterization and prognostic analysis of GSC in PCa. To understand the transcriptional regulation of GSC by E2F transcription factor 1 ( E2F1), we performed chromatin immunoprecipitation quantitative polymerase chain reaction (qPCR). Functional experiments were conducted to validate the effect of GSC on the tumor cellular phenotype and sensitivity to trametinib. Results::GSC expression was elevated in various tumors and significantly correlated with patient prognosis. The alterations of GSC contribute to the progression of various tumors especially in PCa. Patients with PCa and high GSC expression exhibited worse progression-free survival and biochemical recurrence outcomes. Further, GSC upregulation in patients with PCa was mostly accompanied with higher Gleason score, advanced tumor stage, lymph node metastasis, and elevated prostate-specific antigen (PSA) levels. Mechanistically, the transcription factor, E2F1, stimulates GSC by binding to its promoter region. Detailed experiments further demonstrated that GSC acted as an oncogene and influenced the response of PCa cells to trametinib treatment. Conclusions::GSC was highly overexpressed and strongly correlated with patient prognosis in PCa. We found that GSC, regulated by E2F1, acted as an oncogene and impeded the therapeutic efficacy of trametinib in PCa.
