Objective To examine the potential causal associations between different dietary taste preferences and the risk of prostatitis, so as to provide reference for the primary prevention of this disease. Methods Summary-level genome-wide association study(GWAS)data on five taste preferences-sweet, sour, salty, bitter and spicy—were obtained from the GWAS, and GWAS data for prostatitis were sourced from the FinnGen database. The potential causal associations between the dietary taste preferences and risk of prostatitis were analyzed with MR. The inverse variance weighted(IVW)method served as the primary analytical approach. Heterogeneity was assessed using Cochran's Q test. Horizontal pleiotropy was evaluated via the MR-Egger intercept and Mendelian randomization pleiotropy residual sum and outlier(MR-PRESSO)tests. Leave-one-out analysis was performed to evaluate the influence of individual single nucleotide polymorphisms(SNPs)on the causal estimates. Results Preferences for sweet(OR=1.338, 95%CI:1.024-1.748, P=0.033)and salty(OR=1.356, 95%CI:1.092-1.684, P=0.006)tastes showed positive causal associations with the risk of prostatitis, whereas a preference for bitter taste was negatively associated(OR=0.638, 95%CI:0.416-0.978, P=0.039). No significant causal links were observed for sour or spicy taste preferences(P＞0.05). Sensitivity analyses and reverse MR analyses further supported the robustness of the findings.Conclusion Sweet and salty taste preferences may be potential dietary risk factors for prostatitis, while bitter taste preference could play a protective role. Further research is needed to elucidate these causal relationships, which may contribute to developing tailored dietary intervention strategies for prostatitis prevention.

Objective To explore the diagnostic value of endoscopic grading of gastric intestinal metaplasia (EGGIM) score under acetic acid-enhanced narrow band imaging (AA-NBI) observation mode for gastric intestinal metaplasia (GIM). Methods A total of 120 patients who underwent gastroscopy at Jinshan Hospital of Fudan University from February 2022 to February 2023 were selected. All patients underwent both white light and AA-NBI endoscopy, with photographic records of intestinal metaplasia in five areas: greater curvature of antrum, lesser curvature of antrum, greater curvature of corpus, lesser curvature of corpus and incisura. EGGIM score was performed: 0 for no intestinal metaplasia, 1 point for focal intestinal metaplasia (GIM area ratio≤30%), 2 points for extensive intestinal metaplasia (GIM area ratio＞30%), with a total score of 10 points. Targeted biopsies were performed on suspicious GIM lesions found during endoscopy. If no suspicious GIM lesions were observed, random biopsies were performed according to the updated Sydney system. The pathological histological examination results were staged based on the operative link on gastric intestinal metaplasia assessment (OLGIM) system. The diagnostic value of EGGIM score for OLGIM stage Ⅲ-Ⅳ patients was evaluated using receiver operating characteristic (ROC) curves. Results The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of AA-NBI in detecting GIM were 96.3%, 91.6%, 94.5%, 95.0%, and 93.6%, respectively. The area under the ROC curve for EGGIM diagnosing OLGIM stage Ⅲ-Ⅳ was 0.952 (95%CI 0.914-0.990). The optimal cut-off value for EGGIM was 5 points, with a sensitivity of 96.7% (95%CI 87.6%-99.4%) and specificity of 88.1% (95%CI 76.5%-94.7%). Conclusions EGGIM score (≥5 points) under AA-NBI mode has good diagnostic capability for patients with OLGIM stage Ⅲ-Ⅳ.

Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Objective The aim of this study is to discuss the causal relationship between periodontal disease(PD)and prostate cancer(PCa).Methods A two-sample bidirectional Mendelian randomization(MR)analysis based on publicly statistical data from genome-wide association studies(GWAS)was conducted.MR Egger,weighted medium,simple mode and weighted mode were supplemented,while inverse variance weighted analysis(IVW)was the main method of analysis.Heterogeneity testing,pleiotropy testing and leave-one-out testing were used to assess the sensitivity and stabili-ty.Results The results of MR analysis showed that PD had no significant impact on the occurrence of PCa:East Asian(IVW,PD:OR=1.07,P=0.48);European(IVW,PD:OR=1.00,P=0.37,periodontitis:OR=1.03,P=0.14,chronic gingivitis:OR=0.99,P=0.37,chronic periodontitis:OR=1.03,P=0.22).The reverse MR analysis also did not show a causal relationship between PCa and PD:East Asian(IVW,PD:OR=0.97,P=0.22);European(IVW,PD:OR=0.84,P=0.44,periodontitis:OR=1.01,P=0.75,chronic gingivitis:OR=0.93,P=0.23,chronic periodontitis:OR=0.99,P=0.80).The results of other analysis were consistent with those of IVW analysis.Conclusions The results of our two-sample bidirectional MR analysis do not support a causal relationship between PD and PCa.

Objective To evaluate the application effect of perioperative cluster nursing interventions in patients under-going robot-assisted radical prostatectomy.Methods A total of 122 prostate cancer patients who underwent robot-assisted sur-gery from January 2023 to December 2024 were divided into the control group(routine care,55 cases)and the observation group(cluster nursing,67 cases)according to the nursing methods.The psychological status,surgery-related indicators,postoperative recovery,incidence of perioperative complications,and patient satisfaction were compared between the two groups.Results The observation group demonstrated a statistically significant decrease in postoperative anxiety and depression scores compared to the control group(P=0.034,P=0.005).The observation group exhibited shorter operative time and less intraoperative blood loss,with both differences being statistically significant(P=0.016,P＜0.001).In terms of postoperative recovery,the obser-vation group showed faster recovery of bowel function,shorter time for catheter insertion and postoperative hospital stay compared to the control group(P=0.010,P＜0.001,P＜0.001).In the observation group,the incidence of systemic postoperative in-fection was lower than that of the control group(4.5％vs 18.2％,P=0.015).The perioperative hypothermia rate in the obser-vation group was lower than that of the control group(38.8％vs 60.0％,P=0.020).There was no statistically significant difference in postoperative urinary fistula rate between the two groups(P=0.477).The observation group achieved an overall patient satisfaction rate of 98.51％,with higher satisfaction scores compared to the control group(P=0.008).Conclusion Perioperative cluster nursing measures yield favorable outcomes in patients undergoing robot-assisted radical prostatectomy.It can not only shorten the operation time,promote the postoperative recovery of patients,but also reduce the anxiety and depression of patients and complica-tions,and improve patient satisfaction.

Objective:To investigate the effects and underlying mechanisms of silent information regulator 1(SIRT1)on the dysfunction of umbilical vein endothelial cells(HUVECs)induced by oxidized low-density lipoprotein(ox-LDL).Methods:The impact of ox-LDL on the viability of HUVEC was assessed using the Cell Counting Kit-8(CCK-8)assay, which also facilitated the determination of the optimal ox-LDL concentration.Subsequent to ox-LDL treatment, several parameters were evaluated, including reactive oxygen species(ROS)production, apoptosis, migration, and angiogenesis, utilizing a ROS detection kit, flow cytometry, a Transwell migration assay, and an angiogenesis assay, respectively.The expression levels of apoptosis-related proteins, namely cleaved caspase-3(c-caspase-3), Bcl-2-associated X protein(Bax), B-cell lymphoma-2(Bcl-2), SIRT1, and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α), were quantified using Western blot analysis.Adenoviral vectors were employed to either overexpress or silence SIRT1, while the ROS inhibitor N-acetylcysteine(NAC)was applied to assess its effects on cell function.Additionally, PGC-1α acetylation(Ac-Lys)was investigated through co-immunoprecipitation.Results:In the oxidative model of ox-LDL-stimulated HUVECs, compared to controls, we observed a significant increase in ROS-positive cells(35.9±3.1 vs.5.4±0.9), heightened apoptosis(16.3±0.9 vs.7.6±0.7), diminished endothelial cell migration capacity, and reduced angiogenic capacity.Additionally, there was an elevation in the pro-apoptotic protein c-caspase3 and Bax, alongside a decrease in the anti-apoptotic protein bcl-2.Furthermore, SIRT1 expression was increased, as was the expression of PGC-1α.In comparison to the GFP group(28.5±1.9), the reduction in SIRT1 expression resulted in an increase in apoptosis(37.0±1.9).Conversely, overexpression of SIRT1 mitigated ox-LDL-induced apoptosis(25.2±1.6)(all P<0.05).Notably, the expression levels of PGC-1α and SIRT1 exhibited consistent changes: PGC-1α expression increased with SIRT1 overexpression and decreased when SIRT1 expression was reduced(both P<0.05).The administration of NAC to the ox-LDL-treated group led to a reduction in ROS production( t=11.18, P<0.01)and a significant enhancement in cell function.Immunoprecipitation results indicated that SIRT1 overexpression decreased ox-LDL-induced PGC-1α acetylation( t=18.18, P<0.01), whereas silencing of SIRT1 further increased PGC-1α acetylation levels( t=-19.09, P<0.01). Conclusions:SIRT1 is shown to protect against ox-LDL-induced apoptosis and dysfunction in HUVECs by deacetylating and activating PGC-1α, thereby highlighting its therapeutic potential in the context of endothelial cell injury.

AIM:To identify surrogate clinical bio-markers for profiling the eosinophilic status of an individual patient over induced sputum analysis.METHODS:We conducted a cross-sectional study on 100 asthmatic patients whose induced sputum was successfully collected.Subjects were further classified into either EA or NEA based on whether the percentage of sputum eosinophil count(SEC％)was≥3％.Demographic and clinical data were col-lected,including basic information,routine blood tests,lung function tests,bronchodilator reversibili-ty tests,fractional exhaled nitric oxide(FeNO),the Asthma Control Test(ACT)and the Asthma Control Questionnaire(ACQ).All variables significantly asso-ciated with EA were candidates for multivariate lo-gistic regression analysis.A scoring system present-ed as a nomogram for the prediction of EA was de-veloped.RESULTS:In the univariate analysis,com-pared with NEA subjects,those with EA were of older age and had worse asthma control and lung function in addition to higher values of blood eosin-ophils,serum IgE and FeNO.Multivariable logistic regression analysis revealed that age,FeNOx serum IgE and blood eosinophil count(BEC)were identi-fied as independent risk factors for eosinophilic asthma,which were all included in the nomogram.CONCLUSION:A combination assessment including age,FeNOx serum IgE and BEC could be applicable to clinicians in identifying eosinophilic asthma and is easier,faster,more inexpensive and more readily available than the induced sputum test.

Objective To investigate the predictive value of edema metabolic and hematoma dynamics changes on motor and cog-nitive recovery outcomes in patients with intracerebral hemorrhage(ICH).Methods The CT data of ICH patients were collected to evaluate hematoma volume changes from admission to day 3.On day 3,multivoxel magnetic resonance spectroscopy(MRS)was per-formed with region of interest located in the edema region and contralateral normal tissue.Motor and cognitive function recovery was assessed using the simplified F-M scale and the Montreal cognitive assessment(MoCA)on day 3 and at the 3-month follow-up,respec-tively.Overall clinical outcomes were assessed using the Glasgow outcome scale(GOS),and all patients were divided into good and poor outcome groups.Clinical data and metabolic differences in the edema region between the two groups were compared,respec-tively.Logistic regression analysis and receiver operating characteristic(ROC)curves were used to identify and evaluate independent prognostic factors.Subgroup analysis were performed via stratification of hematoma location.Results The logistic regression analy-sis indicated that intraventricular extension,hematoma changes,and the ratio of N-acetyl aspartate(NAA)around the hematoma to contralateral normal brain parenchyma NAA(rNAA)were inde-pendent prognostic factors for poor outcomes(P＜0.05).The area under the curve(AUC)for each factor and the combined model were 0.69,0.73,0.79,and 0.82,respectively.In patients with ICH in the basal ganglia region,△F-M was negatively correlated with hematoma changes and positively correlated with rNAA value(P＜0.001).In patients with ICH in the thalamic and lobar regions,△MoCA was not significantly correlated with hematoma changes(P＞0.05),but was positively correlated with rNAA value(P＜0.001).Conclusion The rNAA holds predictive value for motor and cognitive recovery outcomes following standard treatment.

Breast cancer is a highly prevalent malignant tumor among women worldwide,and its clinical treatment faces significant challenges,such as high postoperative recurrence rates,high metas-tasis rates,and therapeutic resistance.Studies indicate that monocyte-derived immune cells play a critical role in promoting breast cancer progression by establishing an immunosuppressive tumor microenviron-ment and pre-metastatic niche.Monocytic myeloid-derived suppressor cells,tumor-associated macro-phages,and monocyte-derived dendritic cells secrete various cytokines,including interleukins,colony-stimulating factors,tumor necrosis factor,chemokines C-C motif chemokine ligand/C-X-C motif chemo-kine ligand(CCL/CXCL),and growth factors,which activate multiple signaling pathways and promote the development of breast cancer and its metastasis to such organs as bones,lungs,brains and livers through mechanisms involving CCL/CXCL-mediated recruitment,angiogenesis induction,and immune evasion.Therefore,targeting the regulation of monocyte-derived immune cells and their secreted cyto-kines may become a crucial therapeutic approach to breast cancer.This review summarizes the mech-anisms by which monocyte-derived immune cells and their cytokines contribute to the development and metastasis of breast cancer by exploring.It further explores therapeutic strategies targeting these cells and cytokines,such as modulating phenotypic transformation,reprogramming cellular metabolism,and regulating cytokine expression levels.
