Objective: Bladder cancer (BC) is the most common malignant tumour of the urinary system, and radical cystectomy combined with pelvic lymph node dissection (LND) is the standard treatment for BC. We conducted this meta-analysis to explore the efficacy and safety of extended lymph node dissection in radical cystectomy for BC.

Methods: PubMed, Embase, ProQuest PsycINFO, CINAHL, Web of Science and The Cochrane Library databases were searched for studies on extended lymph node dissection during radical BC surgery. The search time limit was from the establishment of the database to December 2023. Screening and quality assessment of literature were conducted. This meta-analysis was conducted to evaluate the influence of different lymph node dissection methods on recurrence-free survival (RFS), overall survival (OS), operation time, 90-day readmission rate and postoperative complication rate.

Results: A total of 15 studies were included, including 4854 patients. All studies were of high quality. This meta-analysis showed no statistically significant difference in the operation time, postoperative complications and 90-day hospitalisation rate between the two groups of patients. The harvested volume of lymph nodes, RFS and OS rate were not statistically different.

Conclusions: Among patients with BC undergoing radical cystectomy, extended lymph node dissection did not have a significant effect on operative time, 90-day readmission rates or postoperative complication rates. Thus, extended lymph node dissection is a safe treatment that does not increase the patient’s surgical risk.

Background: Renal cell carcinoma (RCC), a common and highly invasive malignant tumour, presents clinical challenges due to its propensity for easy metastasis. Inferior vena cava tumour thrombus is a common RCC complication significantly impacting patient prognosis. This study investigates C-X-C chemokine receptor type 2 (CXCR2)/Snail-1-induced epithelial-mesenchymal transition (EMT) in RCC with inferior vena cava tumour thrombus.

Methods: Tissues from 51 RCC patients were analysed for CXCR2 and Snail-1 Messenger Ribonucleic Acid (mRNA) levels using Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). Elevated levels of both were observed in tumour and inferior vena cava tumour thrombus tissues. Using Short Hairpin RNA (shRNA) technology, we inhibited CXCR2 and Snail-1 expression to investigate their impact on EMT, invasiveness, and metastatic potential in RCC cells.

Results: Compared with that in the Short Hairpin RNA-Negative Control (ShNC) group, inhibition of CXCR2 and Snail-1 suppressed the degree of EMT, invasiveness, and metastatic ability of RCC cells (p < 0.01). Further mechanistic studies showed that CXCR2/Snail-1 participated in the formation and progression of RCC by regulating the extracellular signal-regulated kinase 1/2 (ERK1/2) signalling pathways. Additionally, compared with that in the ShNC group, knockdown of CXCR2 and Snail-1 significantly inhibited the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9; p < 0.01), thereby regulating the metastasis of RCC.

Conclusions: Our findings suggest that CXCR2/Snail-1-induced EMT plays an important role in the formation and progression of RCC with inferior vena cava tumour thrombus. CXCR2/Snail-1 participates in the invasion and metastasis of RCC by regulating the expression of multiple signalling pathways and related genes. These results provide new insights and directions for the treatment of RCC.

Background: The management of medication for patients undergoing urological surgery is a subject of ongoing controversy, especially in elucidating the effect of clinical pharmacists on medication rationality. This study aims to assess the influence of clinical pharmacist service on the utilization of antibacterial and hepatoprotective drugs in urological surgery patients during the perioperative period.

Methods: Patients undergoing urological surgery in our hospital from January 2020, to January 2023, were consecutively selected. The patients were divided into control group (routine procedure) and observation group (routine procedure + clinical pharmacist service). The baseline data were balanced by 1:1 propensity score matching (PSM). The t test and chi-square test were used to compare the drug use, adverse reactions, and hospitalization-related indicators between the two groups.

Results: A total of 292 patients were included, with 100 patients in each group after PSM. No significant difference was found in the baseline data between the two groups (p > 0.05). The rationality of drug use (drug type, administration time, course of treatment, and combination) in the observation group was significantly better than that in the control group (χ² = 8.489, 10.607, 10.895, 10.666; p = 0.004, 0.001, 0.001, 0.001). The incidence of adverse reactions (6.00%) and postoperative complications (7.00%) was significantly lower (χ² = 4.903, 5.531; p = 0.027, 0.019). The length of hospital stay and total cost were similar (p > 0.05). The use time and cost of antibacterial and hepatoprotective drugs in the observation group were lower than those in the control group (t = 2.935, 3.450, 3.243, 3.532; p = 0.004, 0.001, 0.001, 0.001). The types and rates of antibacterial and hepatoprotective drugs in the observation group were significantly lower than those in the control group (p < 0.05).

Conclusions: Clinical pharmacist service can effectively improve the rationality of drug use in urological surgery patients and reduce adverse reactions and postoperative complications, hence its clinical promotion value.

Objective: The risk factors of urinary tract infection in elderly patients with type 2 diabetes were investigated.

Methods: A total of 72 elderly patients admitted to our hospital from December 2019 to September 2023 because of with type 2 diabetes were retrospectively included. They were divided into the observation group (n = 35) and control group (n = 37) according to whether they had urinary tract infection. The general clinical data, clinical characteristics and the distribution of pathogenic bacteria in the observation group were collected and analysed. Then, t-tests, chi-square tests, regression analysis and receiver operating characteristic curve analysis were conducted.

Results: Escherichia coli (E. coli) accounted for 51.43% of the pathogenic bacteria in the observation group, whereas Klebsiella pneumoniae (K. pneumoniae) accounted for 22.86%. The remaining pathogens accounted for 2.86% each. Differences in gender, course of disease, glycosylated haemoglobin and comorbid urinary calculi were found between the groups (p < 0.05); These factors were all risk factors for concurrent urinary infection, and the odds ratios were all >1. The obtained values for gender, disease course, glycosylated haemoglobin and comorbid urinary calculi were respectively 0.594, 0.654, 0.738 and 0.696 (area under the curve); 0.971, 0.714, 0.800 and 0.743 (sensitivity); 0.216, 0.595, 0.676 and 0.649 (specificity); And 0.188, 0.309, 0.476 and 0.392 (Youden index).

Conclusions: Common pathogens in elderly people with type 2 diabetes and comorbid urinary tract infection are E. coli and K. pneumoniae. Risk factors include gender, disease duration, glycosylated haemoglobin and urinary stones. The prompt identification of pathogens and risk factors facilitates clinical treatment, reducing infection incidence.

Background: Plaque incision and grafting (PEG) is a primary surgical therapy for severe penile curvature in Peyronie’s disease (PD); However, it can increase the risk of erectile dysfunction (ED), particularly in patients with pre-operative mild ED. Soft penile prosthesis (SPP) implantation is a viable treatment option in such cases. This study aims to compare the outcomes of PEG-only approach to PEG plus SPP implantation.

Methods: Between 2010 and 2019, 32 patients with PD and mild ED (5-item version of the International Index of Erectile Function scores: 17–21) underwent PEG surgery. Two groups were defined based on the surgery type: PEG-only and PEG plus SPP. The long-term outcomes included correction of penile bending, erection quality, intercourse ability, penile length and sensitivity. The overall satisfaction and impact of surgery on sexual activity and quality of life were also assessed.

Results: Of the 32 patients, 13 (40.6%) underwent PEG-only surgery, whereas 19 (59.4%) underwent PEG plus SPP. No significant differences were noted between the groups regarding pre-operative characteristics (all p > 0.1) or intra- and post-operative complication rates (all p > 0.2). The median patch area was larger in the PEG-only group (28 cm² vs. 16.2 cm²; p = 0.001), whereas patients in the PEG plus SPP group were more likely to receive a single patch implant (100% vs. 53.8%; p < 0.001). The penile length increased in 18 patients (61.6%), with significant differences between the two groups (30% vs. 81.2%; p = 0.03). Overall, 14 patients (53.8%) reported greater satisfaction with their sexual life post-operatively, with comparable rates between the groups (p = 0.2). No significant differences were found in the post-operative 5-item version of the International Index of Erectile Function scores or severe post-operative ED (all p > 0.5).

Conclusions: SPP placement during corporoplasty in patients with mild ED is safe and feasible, and it may be a suitable option for patients uncertain about inflatable prosthesis placement. The use of SPP resulted in longer penile lengths and necessitated smaller grafts. However, further data are required to understand the long-term clinical implications of this approach.

Object: This study aimed to analyse the risk factors and prognosis of sepsis complicated with acute kidney injury (AKI).

Methods: The clinical data of 324 patients with sepsis in the nephrology department of our hospital from January 2022 to January 2023 were collected. A total of 188 patients with AKI were the occurrence group, and 136 patients without AKI were the non-occurrence group. The influencing factors and prognosis of sepsis complicated with AKI were analysed.

Results: We observed significant differences in Acute Physiology and Chronic Health Evaluation II (APACHE II), total length of hospital stay, Intensive Care Unit (ICU) stay, mechanical ventilation support, diabetes mellitus and urine volume >1500 mL between the two groups (p < 0.05). After a follow-up period of 1 month, 125 (66.49%) of 188 patients with sepsis complicated with AKI died, and 63 (33.51%) survived. The results of logistic regression analysis showed that Sequential Organ Failure Assessment (SOFA), APACHE II, mechanical ventilation support, diabetes, urine volume >1500 mL and serum creatinine were independent risk factors of sepsis complicated with AKI (p < 0.05). Moreover, SOFA, APACHE II, ICU admission days, mechanical ventilation support, serum creatinine and non-continuous renal replacement therapy were independent risk factors of death in patients with sepsis complicated with AKI (p < 0.05).

Conclusions: SOFA, APACHE II, ICU admission days, mechanical ventilation support, serum creatinine and non-continuous renal replacement therapy may be the influencing factors leading to death in patients with sepsis complicated with AKI. Early clinical intervention should be performed.

Objective: This study aimed to investigate the effect of electroacupuncture combined with pelvic floor muscle exercise in the treatment of female overactive bladder (OAB).

Methods: The clinical data of 134 female patients with OAB admitted to our hospital from April 2022 to June 2023 were retrospectively analysed. The patients were divided into the combination group (n = 74) and the single group (n = 60). The general demographic data, total effective rate, pad weight, female sexual function index (FSFI) score, oxford muscle grading scale and incontinence impact questionnaire short form (IIQ-7) were collected. Propensity score matching (PSM) was used to match the baseline data of the two groups at 1:1 ratio, and t test, chi-square test and analysis of variance were used for calculation.

Results: A total of 90 patients were selected after PSM. No significant difference in baseline data was found between the two groups (p > 0.05). Before treatment, no significant difference in FSFI score, oxford muscle grading scale and IIQ-7 score was found between the two groups (p > 0.05). The total effective rate of the combination group was higher than that of the single group (p < 0.05). After 3 weeks and 1 month of treatment, in addition to orgasm and sexual desire, the scores of sexual excitement and sexual satisfaction in the combination group were higher than those in the single group (p < 0.05). The combination group displayed higher oxford muscle grading scale and lower IIQ-7 and pad weight than the single group, and the differences were statistically significant (p < 0.05).

Conclusions: The effect of electroacupuncture stimulation combined with pelvic floor muscle exercise is more significant, which can alleviate urinary symptoms, reduce urine leakage, enhance pelvic floor muscle strength and alleviate sexual dysfunction.

Objective: To study the effect of high-simulation teaching on nursing students’ learning knowledge related to stoma tube care after ureteral flexible mirror lithotripsy.

Methods: A total of 80 nursing students who were admitted to our hospital from January 2020 to December 2022 were selected as the study objects. They were divided into the control group (traditional teaching) and observation group (high-simulation teaching based on traditional teaching) in accordance with teaching method. General demographic information and specialty theory, Objective Structured Clinical Examination, Chinese Critical Thinking Disposition Inventory, Teaching Quality Evaluation Scale and System for Evaluation of Teaching Qualities scores were collected from both groups of nursing students. Data were analysed with t- and chi-square tests.

Results: The general demographics of the two groups were not statistically significantly different (p > 0.05). No significant differences in examination scores, clinical skills, thinking skills, teaching quality and nursing students’ satisfaction were found between the two groups before teaching (p > 0.05). Examination scores, clinical skills, thinking skills, teaching quality and nursing students’ satisfaction were higher in the observation group than in the control group after teaching (p < 0.05).

Conclusions: High-simulation teaching can effectively improve theoretical and clinical skill examination results, strengthen critical thinking, and improve teaching quality and nursing students’ overall satisfaction with teaching. Therefore, it has application value.

Objective: To retrospectively analyse the effects of cinobufotalin capsule combined with zoledronic acid on pain symptoms and clinical efficacy of prostate cancer patients with bone metastases.

Methods: Patients with prostate cancer with bone metastasis admitted to our hospital from January 2021 to December 2022 were selected as study subjects. They were divided into the control group (treated with zoledronic acid) and the combined group (cinobufotalin capsules were added on the control group basis) according to different recorded treatment methods. The efficacies of the two groups after matching, lumbar L_1-4 bone mineral density (BMD), serum calcium, serum phosphorus, visual analogue scale (VAS) score and Karnofsky performance status (KPS) score before and after treatment were compared, and adverse reactions were statistically analysed.

Results: A total of 102 patients were included in the study, encompassing 52 patients in the combined group and 50 patients in the control group. After 1:1 preference score matching, 64 patients were included in the two groups. No significant difference in baseline data was found between the two groups (p > 0.05). The total effective rate of the combination group was higher than that of the control group (p < 0.05). No significant differences in L_1-4 bone mineral density, serum calcium and phosphorus, VAS score and KPS score were observed between the two groups prior to treatment (p > 0.05). After treatment, the L_1-4 bone mineral density (BMD) and KPS score of the combined group decreased to less than those of the control group, the VAS score was lower than that of the control group, and the serum calcium and phosphorus level increased but less than that of the control group (p < 0.05). No significant difference in adverse reactions was found between the two groups (p > 0.05).

Conclusions: Cinobufotalin capsule combined with zoledronic acid had ideal efficacy in the treatment of prostate cancer in patients with bone metastasis. This approach could improve their bone density and quality of life, improve their calcium and phosphorus metabolism, reduce their pain symptoms and provide increased safety. It may have an important guiding role in formulating future clinical treatment plans for patients with prostate cancer and bone metastasis.

Objective: The objective of this study was to examine the influence of total intravenous anaesthesia (TIVA) compared to combined intravenous and inhalation anaesthesia (CIIA) in paediatric patients undergoing renal biopsy.

Methods: A total of 86 children with nephrotic syndrome, acute glomerulonephritis, chronic glomerulonephritis, IgG nephropathy, systemic lupus erythematosus and purpura nephritis were selected from January 2018 to January 2023 in our hospital. All children were divided into the total intravenous anaesthesia group and intravenous inhalational anaesthesia group according to the anaesthesia method. The experimental group comprised 46 children with renal diseases who underwent static aspiration compound anaesthesia during renal biopsy at our hospital from January 2018 to January 2023. Conversely, the control group included 40 children with renal diseases who underwent total intravenous anaesthesia during renal biopsy at the hospital within the same period. Hemodynamic parameters, such as mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SPO₂), were assessed at four different time points: Before anesthesia induction (T0), during anesthesia induction (T1), after anesthesia induction (T2), and at the conclusion of the surgery (T3). Puncture success rate, time to renal puncture, time to get out of bed, postoperative recovery from anaesthesia (including time to postoperative awakening and time to return to spontaneous respiration) and incidence of adverse anaesthetic reactions were also included.

Results: We observed notable variations in HR and MAP at T2 and T3, as well as SPO₂ levels, duration of awakening from anaesthesia and time taken to resume spontaneous respiration between the two groups at T2 (p < 0.05). No statistically significant variances were detected between the two groups concerning adverse reactions to anaesthesia, puncture success rate, duration to renal puncture and time to mobilisation from bed (p > 0.05).

Conclusions: In conclusion, compared with the total intravenous anaesthesia, the implementation of the sedation-aspiration-combined anaesthesia in renal biopsy in children with renal disease features less haemodynamic fluctuation, better postoperative anaesthesia recovery and does not increase the incidence of adverse reactions.

Background: This work aimed to investigate the potential role of abnormal lipid metabolism in the development of prostate cancer (PCa).

Methods: A retrospective study design was used. The clinical data of 520 patients who underwent rectal prostate biopsy in our hospital from January 2020 to June 2023 were analysed. The patients were enrolled and divided into the anterior PCa group including 112 patients and benign prostatic hyperplasia (BPH) group including 408 patients. Univariate and multivariate logistic regression analyses were performed for the two patient groups, and further comparisons were made according to the Gleason score and TNM staging.

Results: Low-density lipoprotein cholesterol (LDL-C) level may be an independent risk factor for PCa, and it was significantly associated with the risk of PCa (odds ratio (OR) = 1.363, p = 0.030). Patients with PCa were further divided into the low risk group and the high risk group according to the Gleason score. Univariate analysis (p = 0.047) and logistic regression analysis (OR = 2.249, p = 0.036) revealed that LDL-C was a significant factor influencing the Gleason score. Patients with PCa were categorised into four groups based on TNM staging. One-way analysis of variance (ANOVA) analysis (p = 0.015) and ordinal logistic regression analysis (OR = 2.414, p = 0.007) demonstrated that LDL-C was a significant factor influencing TNM staging.

Conclusions: This study revealed the important role of LDL-C in the development of PCa, highlighting its influence as an independent risk factor. Thus, LDL-C may promote the proliferation and invasion of PCa cells.

Midline prostatic cysts are infrequent and mostly asymptomatic. We presented a striking case of a giant midline cyst and detailed its diagnosis, evolution, and treatment. From this case, we offered a comparison of congenital intraprostatic midline cysts, namely, Müller’s cysts and utricle cysts. A 40-year-old male experienced recurrent urinary retention. A 10 × 11 mm² cyst in the mid-prostatic region was diagnosed through transrectal ultrasound, leading to a transperineal puncture as a minimally invasive intervention. Seven years later, the cyst recurred, manifesting obstructive symptoms such as a weak urinary stream, frequent urination, and residual urine sensation. Laparoscopic surgery was then performed for the confirmed 98 × 13 mm² cystic recurrence. The postoperative course was favourable with no complications. Symptoms were completely resolved, which was maintained over a three-year follow-up period. The therapeutic approach to midline cysts targets symptomatic cases or infertility, ranging from cyst puncture to transurethral endoscopic treatment. Recurrence after minimally invasive interventions is a challenge, with laparoscopic surgery as an alternative post-failed conservative approach. Although total cyst removal risks adjacent structure damage, marsupialisation improves the clinical outcomes. In summary, symptomatic midline prostatic cysts present challenges owing to recurrences after minimally invasive approaches. Enhanced laparoscopic techniques offer a solution, particularly in highly symptomatic cases requiring definitive treatment, as illustrated by this outstanding case report.

Objective: We aimed to investigate the value of magnetic resonance imaging (MRI) radiomics combined with serum prostate-specific antigen (PSA) in predicting the extracapsular extension (ECE) of prostate cancer.

Methods: In total, 213 patients with prostate cancer admitted to our hospital from May 2021 to April 2023 were retrospectively enrolled as observation subjects. Based on the presence or absence of extracapsular extension, the patients were divided into occurrence (n = 70) and non-occurrence (n = 143) groups. The clinical data, PSA levels, Prostate Imaging Reporting and Data System (PI-RADS®), and MRI-ECE scores of the two groups were compared.

Results: In total, 80 patients were included in the occurrence (n = 40) and non-occurrence groups (n = 40), and no statistical significance was observed in the baseline data of the two groups. Preoperative PSA levels were significantly higher in the occurrence group than in the non-occurrence group, and the PI-RADS and MRI-ECE scores of each group differed significantly (p < 0.05). The area under the curve (AUC) for the combined determination of PSA levels and PI-RADS and MRI-ECE scores was 0.900, which was significantly higher than the AUC for the individual determination of the mentioned indicators (p < 0.05).

Conclusions: The combination of MRI radiomics and PSA can accurately predict the extracapsular extension of prostate cancer; Thus, it is a favorable reference for subsequent precise diagnosis and treatment.

Objective: To analyse the incidence and influencing factors of delirium during recovery in urological postoperative patients undergoing sevoflurane anaesthesia.

Methods: The clinical data of patients undergoing sevoflurane anaesthesia in the urology surgery department in our hospital from January 2022 to December 2022 were retrospectively analysed. The incidence of delirium during the recovery period was recorded by using the Chinese version of the Confusion Assessment Method (CAM) for Severity of Delirium after surgery, and the patients were divided into occurrence and non-occurrence groups. Whether delirium occurred during recovery was determined through univariate analysis. In binary logistic regression analysis, the occurrence of emergence delirium was the dependent variable, and the variables with statistical differences in the univariate analysis were the independent variables. The influencing factors of emergence delirium in post-urological surgery patients who underwent sevoflurane anaesthesia were determined.

Results: Delirium during recovery occurred in 10 of 100 patients (10.00%). Odds ratio (OR) of age (OR = 1.445, p = 0.022), history of diabetes (OR = 1.798, p = 0.010), operation time (OR = 1.670, p = 0.008), American Society of Anesthesiologists (ASA) classification (OR = 1.740, p = 0.006) and sevoflurane inhalation concentration (OR = 1.890, p = 0.001) are the influencing factors of postoperative delirium in urologic patients undergoing sevoflurane anaesthesia.

Conclusions: Age, history of diabetes, operation time, ASA classification and sevoflurane inhalation concentration are the influencing factors.

Objective: A retrospective study was performed to analyse the influencing factors of stricture recurrence after urethroplasty and to establish a predictive nomogram model.

Methods: The clinical data of patients who underwent urethroplasty in our hospital from January 2021 to June 2023 were retrospectively analysed. Depending on whether stenosis occurs six months after surgery, the patients were divided into recurrence and nonrecurrence groups. Logistic regression analysis was performed on the indicators with statistically significant differences between the two groups in single factor analysis to analyse the influencing factors of postoperative recurrence risk of stricture. X64.4.1.3 version R language and external source packages were used to build the nomogram model. The nomogram was internally validated through 10-fold cross-validation, and C-index was calculated. The area under the curve (AUC) of the receiver operating characteristic curve was employed to evaluate the results of the internal validation.

Results: Amongst 105 patients who underwent urethroplasty in our hospital, 15 patients with recurrence were included in the recurrence group, and 90 patients without recurrence were included in the nonrecurrence group. The length of stricture segment, history of urethroplasty and smoking history within 3 months before surgery were risk factors for stricture recurrence, with odds ratio (OR) values of 1.874 (95% CI: 1.103–5.725), 1.670 (95% CI: 1.105–2.904) and 1.740 (95% CI: 1.456–5.785), respectively. The constructed nomogram obtained an average AUC of 0.842 and an average C-index of 0.794, calculated after 200 times of 10-fold cross-validation.

Conclusions: From the data of this study, it can be deduced that the influencing factors of stricture recurrence after urethroplasty include the length of stricture segment, history of urethroplasty and smoking history of 3 months before surgery. Using the above factors as a basis to construct a predictive nomogram model is helpful to screen high-risk patients with recurrence of stricture after urethroplasty.

Background: Chronic inflammation is associated with various malignant tumors. Bacterial lipopolysaccharides (LPSs) play a significant part in the event and development of prostate cancer. Dishevelled segment polarity protein 3 (DVL3) is a shared component of the Wnt/β-catenin and Notch signaling pathways, which are involved in tumor progression, chemoresistance, and maintenance of stem cell-like properties. According to reports, prostatic cancer cell invasion and proliferation are mediated by toll-like receptor 4 (TLR4). However, the role and regulation of DVL3 in prostate cancer and its relationship with TLR4 remain unclear.

Methods: Survival curves were plotted to evaluate the relationship between DVL3 expression and prognosis in patients with prostate cancer. DVL3 was silenced in PC3 and DU145 cells using small interfering RNAs (siRNAs). Subsequently, cell counting kit-8 (CCK-8) assay, colony formation assay, transwell migration assay, and quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) were performed to investigate the role of DVL3 in cell proliferation and migration in vitro. The protein markers of potential pathways were analyzed via western blotting.

Results: DVL3 expression was linked to prognosis in patients with prostate cancer; In particular, patients with high DVL3 expression had a poor prognosis. LPS stimulation increased (p < 0.01) the expression of DVL3 in PC3 cells. DVL3 regulated tumor cell proliferation and migration by mediating the increase (p < 0.01) in TLR4 expression. Knockout of TLR4 validated that TLR4 played a crucial role in LPS-induced DVL3 expression. Silencing of DVL3 decreased (p < 0.01) the LPS-induced proliferation and migration of PC3 cells.

Conclusions: Bacterial LPS-induced DVL3 promoted the multiplication and migration of prostate cancer cells through the TLR4 pathway. This study offers a valuable reference for the development and clinical application of targeted drugs for prostate cancer.

Purpose: This study aimed to determine the influence of miR-1297 on kidney injury in rats with diabetic nephropathy (DN) and its causal role.

Methods: A DN rat model was established through right kidney resection and intraperitoneal injection of streptozotocin (STZ). Sham rats did not undergo right kidney resection or STZ injection. The DN rats were divided into the DN model and antagomiR-1297 treatment groups. Kidney morphology was observed using hematoxylin and eosin staining. Renal function indices, including blood urea nitrogen (BUN), serum creatinine (SCr), and urinary protein, were measured using kits. Levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-1β, superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) were determined through enzyme-linked immunosorbent assay (ELISA). Fibrin (FN), collagen type I (Col I), and α-smooth muscle actin (α-SMA) were assessed through western blotting and real-time reverse transcription-polymerase chain reaction. Apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling staining. miR-1297 targets were predicted using bioinformatic software and verified through luciferase reporter assay. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN)/phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway expression was analyzed through western blotting.

Results: AntagomiR-1297 reduced BUN (p = 0.005), SCr (p = 0.012), and urine protein (p < 0.001) levels and improved kidney tissue morphology. It prevented renal interstitial fibrosis by decreasing FN, Col I, and α-SMA protein levels (all p < 0.001). AntagomiR-1297 increased SOD (p = 0.001) and GSH-Px (p = 0.002) levels. Additionally, it reduced levels of cell inflammatory factors, including TNF-α, IL-6, and IL-1β (all p < 0.001), and alleviated apoptosis (p < 0.001) in rat kidney tissue with DN. miR-1297 was pinpointed as a target for PTEN. AntagomiR-1297 increased PTEN expression and suppressed PI3K and AKT phosphorylation (all p < 0.001).

Conclusions: AntagomiR-1297 can mitigate renal fibrosis, renal inflammation, apoptosis, and oxidative stress levels through the PTEN/PI3K/AKT pathway.

Background: In recent years, significant attention has been directed towards long non-coding RNA NUT family member 2A antisense RNA 1 (NUTM2A-AS1) for its oncogenic role in tumours. This study aimed to investigate the functional and molecular mechanisms underlying NUTM2A-AS1 in prostate cancer (PCa).

Methods: NUTM2A-AS1, miR-376a-3p, and protein arginine methyltransferase 5 (PRMT5) levels were assessed in PCa samples and matched non-cancerous prostate samples. The DU145 cell line was conditioned to undergo transfection with relevant plasmids, and a cell counting kit-8 assay was performed to evaluate cell proliferation. A Transwell assay was conducted to analyse cell migration or invasion. Cell apoptosis was assessed using an annexin V-fluorescein isothiocyanate/propidium iodide apoptosis detection kit and flow cytometry. A tumour sphere formation assay was conducted to assess the ability of PCa cells to form tumour spheres.

Results: We found elevated expression of NUTM2A-AS1 and PRMT5 and decreased expression of miR-376a-3p in PCa samples. Inhibition of NUTM2A-AS1 or overexpression of miR-376a-3p led to reduced cell proliferation and diminished cancer stem cell-like traits in vitro. NUTM2A-AS1 regulated miR-376a-3p through competitive absorption, thereby modulating PRMT5. Up-regulation of PRMT5 nullified the therapeutic effects of inhibiting NUTM2A-AS1 or overexpressing miR-376a-3p in DU145 cells.

Conclusions: NUTM2A-AS1 promotes cancer stem cell-like traits in PCa cells by targeting PRMT5 through miR-376a-3p. Therefore, these NUTM2A-AS1-based novel insights into tumour therapy hold promise for patients with PCa.

Objective: To explore the efficacy of combining the prognostic nutritional index (PNI) and the lymphocyte:monocyte ratio (LMR) for patients with muscle-invasive bladder cancer (MIBC).

Methods: Of 172 patients who were diagnosed with MIBC in our hospital, 94 were eligible for the study. The clinical data of the 94 patients with MIBC were collected. The patients were divided according to the optimal cut-off values for the preoperative PNI and LMR into a low-PNI subgroup (PNI <44.15, 52 patients), a high-PNI subgroup (PNI ≥44.15, 42 patients), a low-LMR subgroup (LMR <2.98, 50 patients) and a high-LMR subgroup (LMR ≥2.98, 44 patients). The area under the receiver operating characteristic (ROC) curve (AUC) was used to analyse the efficacy of the PNI and the LMR in predicting the prognosis of patients with MIBC. Univariate and multivariate logistic regression analyses were performed to evaluate prognostic factors for patients with MIBC. Kaplan–Meier (K‒M) survival analysis was used for overall survival (OS) analysis to explore the ability of the PNI combined with the LMR to predict the prognosis of patients with MIBC.

Results: The optimal cut-off values for the preoperative PNI and the preoperative LMR were 44.15 and 2.98, respectively, on the basis of ROC curves. ROC curve analysis revealed that the PNI (AUC = 0.720, sensitivity 65.9%, specificity 74.50%, Youden index 0.399) and the LMR (AUC = 0.724, sensitivity 65.9%, specificity 70.0%, Youden index 0.395) both had good prognostic efficacy for patients with MIBC. The results of univariate and multivariate logistic regression analyses showed that preoperative PNI <44.15 was an independent risk factor for OS in patients with MIBC (p = 0.027). Based on K‒M survival curve analysis, patients with PNI <44.15 and LMR <2.98 had the shortest OS (p = 0.00002).

Conclusions: Low preoperative PNI and LMR values are indicative of poor prognosis in patients with MIBC. The efficacy of their combination was better than that of the factors independently.

Objective: This study aims to investigate the influence of delirium following radical prostatectomy on cognitive function and health perception during the recovery period.

Methods: Data were collected from patients who underwent radical prostatectomy at our institution between May 2020 and May 2022. Postoperative delirium was assessed using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), categorising patients into delirium and non-delirium groups. The Montreal Cognitive Assessment (MoCA) and the Brief Illness Perception Questionnaire (BIPQ) were employed to evaluate patients’ mental health pre-and post-surgery. Comparative analyses were conducted between patients with and without delirium in the critical care unit, and correlation analyses were performed.

Results: The study revealed a delirium incidence rate of 19.13%. Patients in the delirium group exhibited significantly higher age and ICU length of stay compared to those without delirium (p < 0.05). No significant differences were observed in MoCA scores one day before surgery and seven days after surgery, as well as BIPQ scores one day before surgery, five days after surgery and seven days after surgery between the delirium and non-delirium groups (p > 0.05); However, the MoCA scores in the delirium group were significantly lower than those of the non-delirium group on the second and fifth days post-surgery. Additionally, the BIPQ scores in the delirium group were significantly higher than those in the non-delirium group two days after surgery (p < 0.001). A moderate negative correlation was observed between MoCA scores and CAM-ICU scores, and a moderate positive correlation was identified between BIPQ scores and CAM-ICU scores (p < 0.001).

Conclusions: Patients experiencing delirium after radical prostatectomy are at a higher risk of cognitive function impairment and disease threat perception. A significant correlation exists between postoperative delirium and cognitive function as well as health perception.

Background: Due to the low incidence of nonurothelial bladder cancer (NUBC), there is limited evidence in the field of evidence-based medicine regarding treatment modalities for such diseases. The purpose of our study was to explore the clinicopathological characteristics and prognostic factors of NUBC.

Methods: We retrospectively analyzed the clinical data of 135 bladder squamous cell carcinoma (SqCC) and adenocarcinoma (AC) patients treated at the Second Hospital of Tianjin Medical University between October 2011 and February 2022, including 70 SqCC and 65 AC patients; We also analyzed 145 patients from the Surveillance, Epidemiology, and End Results (SEER) database from 2011 to 2020, including 108 SqCC and 37 AC patients. Clinicopathological characteristics and prognoses were compared between the SqCC and AC groups. Additionally, the Kaplan‒Meier method and log-rank tests were used to perform survival analysis, and the Cox proportional hazard model was applied to analyze clinical factors affecting prognosis.

Results: Comparisons of clinicopathological characteristics between the SqCC and AC groups revealed that age at diagnosis (p < 0.001, p < 0.001), tumor diameter (p < 0.001), tumor location (p = 0.002), and surgical approach (p < 0.001) were significantly different. Univariate and multivariate Cox regression analyses indicated that lymph node metastasis (p = 0.031), advanced pT stage (p < 0.001), and SqCC (p < 0.001) were independent risk factors affecting the prognosis of NUBC patients, and comparisons of clinicopathological characteristics between the SqCC and AC groups from the SEER database revealed that tumor diameter (p < 0.001), tumor location (p = 0.033), tumor number (p = 0.004), surgical approach (p = 0.005), and lymph node metastasis (p = 0.017) were statistically significant. Univariate and multivariate Cox regression analyses indicated that surgical approach (p = 0.003), lymph node metastasis (p = 0.005), age at diagnosis (p = 0.004), and SqCC (p = 0.028) were independent risk factors affecting the prognosis of NUBC patients.

Conclusions: NUBC is a rare pathological subtype of bladder cancer with a poor prognosis, and SqCC and AC are the most common histological subtypes of NUBC. Early diagnosis, radical cystectomy, and a focus on patients with lymph node metastasis, advanced pT stage, or SqCC may be helpful for ensuring the survival of NUBC patients.

Objective: To explore the effect of acupuncture at Fuguan point combined with tamoxifen citrate tablet on sperm motility parameters.

Methods: A total of 115 individuals with asthenospermia were categorized based on different treatment regimens: 53 patients in the control group (receiving tamoxifen citrate tablets) and 62 patients in the observation group (undergoing acupoint acupuncture in conjunction with tamoxifen citrate tablets). Both groups underwent a 3-month treatment period. The computer-assisted sperm analysis system was employed to measure various motility parameters of human sperm, including sperm motility rate, average path velocity (VAP), lateral swing amplitude (ALH), percentage of class a sperm, and percentage of class a + b sperm.

Results: Prior to treatment, no statistically significant differences were observed between the two groups in terms of sperm motility rate, VAP, ALH, percentage of class a sperm, and percentage of class a + b sperm (p > 0.05). Following treatment, both groups exhibited significant enhancements in sperm motility rate, VAP, ALH, percentage of class a sperm, and percentage of class a + b sperm compared to pretreatment levels (p < 0.05). Furthermore, all measured indicators in the observation group demonstrated significantly superior improvements than those of the control group, with the differences proving statistically significant (p < 0.05).

Conclusions: The combination of acupuncture at Fusiguan point and tamoxifen citrate tablets exerts a notably positive effect on sperm motility in individuals diagnosed with asthenospermia.

Background: Wilms’ tumour is the most prevalent abdominal malignancy in children. This study focused on the mechanism of the miR-590-3p/Dickkopf 1 (DKK1) axis in Wilms’ tumour.

Methods: The mRNA levels of miR-590-3p and DKK1 in 49 pairs of Wilms’ tumour pathological specimens and normal tissues were determined using real-time quantitative polymerase chain reaction (RT-qPCR). Wilms’ tumour cells’ invasion ability and proliferative ability were assessed using a Transwell assay and Cell Counting Kit-8 (CCK-8) assay, respectively. Dual-luciferase assay was performed to evaluate the potential relationship between miR-590-3p and DKK1 in Wilms tumour. Furthermore, a mouse transplanted tumour model was constructed to explore the function of miR-590-3p inhibitor on Wilms’ tumour growth in vivo.

Results: DKK1 emerged as a target gene of miR-590-3p in Wilms’ tumour. DKK1 expression was downregulated (p < 0.01), but miR-590-3p was overexpressed (p < 0.01) in Wilms’ tumour tissues compared to normal tissues. miR-590-3p overexpression accelerated Wilms’ tumour invasive ability and cell proliferation (p < 0.01). Additionally, DKK1 partially reversed miR-590-3p-induced proliferation (p < 0.05) and invasion ability (p < 0.01). Furthermore, downregulation of miR-590-3p restrained the growth rate of transplanted tumours in nude mice (p < 0.01).

Conclusions: Through the regulation of DKK1, miR-590-3p accelerated the invasion and proliferation of Wilms’ tumour. The study suggests that the miR-590-3p/DKK1 axis represents a novel mechanism in Wilms’ tumour.

Background: Evidence regarding the relationship between the laterality of lymph node invasion (LNI) and the prostatic lobe affected is limited. Our aim was to review our records of patients with exclusively unilateral localised prostate cancer (PCa) with metastatic LN involvement.

Methods: Between 2006 and 2023, after radical prostatectomy and extended pelvic lymphadenectomy at our centre, thirty patients with intermediate-high risk unilateral PCa and pN1 disease were identified. To perform a retrospective study, data were obtained from a prospective collected database approved by the ethical committee at the Valencian Oncology Institute Foundation. Descriptive and comparative statistical analysis was made using software R. The Fisher’s Exact test was employed to analyse the categorical variables. In terms of continuous variables, both tumour volume and number of nodes retrieved exhibited normality; Hence Student’s T-test was employed. Mann-Whitney U test was utilized for the number of positive nodes.

Results: The median age and prostate specific antigen (PSA) at diagnosis were 66 years old (interquartile range (IQR): 63.3–70.9) and 14.6 ng/mL (IQR: 7.4–21.5), respectively. Median follow-up time was 67 months (IQR: 35.9–92.9). Nineteen patients (63%) had a Gleason score of 7, and the rest had a Gleason score of 8–10. Most patients (73%) had locally advanced disease. Baseline characteristics were comparable between groups (p-value > 0.05). Twenty-two patients (73%) had concordance between the laterality of the PCa lesion and the LNI. All the patients with right prostatic cancer had exclusive ipsilateral LNI.

Conclusions: In our experience, the majority of patients with unilateral PCa had exclusively ipsilateral LNI. However, sparing contralateral LN dissection in unilateral PCa should not be an option. To date, extended pelvic LN dissection remains the gold standard for N-staging and cannot be replaced yet by unilateral pelvic LN dissection until high quality evidence supports this scenario.

Background: Renal cell carcinoma (RCC) is one of the most common malignancies of the urinary system and ferroptosis is considered as a promising therapeutic approach for treating RCC. Ginsenoside Rh4 (Rh4) was proved to have anticancer properties and play roles in ferroptosis. This study aimed to investigate the potential of ginsenoside Rh4 (Rh4) in enhancing the sensitivity of renal cell carcinoma (RCC) cells to ferroptosis and to elucidate the underlying mechanisms.

Methods: RCC cell lines of 786-O and ACHN were treated with RAS-selective lethal 3 (RSL3) and/or Rh4. Cell-viability assays were used to determine how Rh4 affected the sensitivity of RCC cells to RSL3-induced ferroptosis. Quantitative real-time polymerase chain reaction was conducted to examine the levels of ferroptosis-related genes. Additionally, the knockdown of nuclear factor E2-related factor 2 (NRF2) was performed to investigate the role of NRF2 in mediating the effects of Rh4.

Results: RSL3 suppressed the progression of RCC cells by inducing ferroptosis. Furthermore, Rh4 led to more RCC sensitivity to ferroptosis induced by RSL3. Rh4 downregulated the ferroptosis-related gene expression including superoxide dismutase 1 (p < 0.01), glutathione peroxidase 4 (p < 0.01), and catalase (p < 0.01), which was attenuated by NRF2 knockdown. This finding suggested that Rh4 exerted its sensitising effect on ferroptosis through the NRF2 pathway.

Conclusions: Rh4 made RCC cells more sensitive to ferroptosis by inhibiting the NRF2 signaling and suppressing the expression of antioxidant enzymes. Therefore, combining Rh4 with ferroptosis-inducing reagents to treat RCC had potential therapeutic application.

Background: The conventional approach for managing ureteral stenosis involves the placement of a double-J stent. In recent years, the utilisation of Allium ureteral stent (URS) has emerged as a novel treatment alternative for ureteral stenosis. Allium URS has several advantages over traditional stents, including an extended indwelling time and reduced incidence of complications. The number of cases reported worldwide on the use of Allium URS in the treatment of ureteral stenosis is currently limited. In this paper, we present the details of a case involving the use of an Allium URS to treat ileal-ureteral anastomotic stenosis in a 67-year-old patient. We aim to assess the feasibility of using Allium URS in such cases.

Case Presentation: A 67-year-old Chinese woman was referred to our hospital for the treatment of left lumbago. Urography showed left ileal-ureteral anastomotic stenosis. Computed tomography (CT) revealed severe hydronephrosis in the left kidney. Subsequently, an Allium URS was implanted via ureteroscopy. We found no instances of haematuria, lumbago or urinary tract irritation during the follow-up period. After 8 months, the patient was readmitted because of left lumbago. CT re-examination revealed that the left hydronephrosis had modestly improved. The Allium URS had detached and showed stone formation on its surface. For further treatment, ureteroscopy was performed and a new Allium URS was implanted. At 3-month follow-up, CT re-examination demonstrated that the stent had dislodged again but that the hydronephrosis in the left kidney had remarkably improved. Cystoscopy revealed that the stent had completely detached and that wall stones had attached on this surface. The stent was removed via cystoscopy. After 1 month, CT scanning showed that the left hydronephrosis of the patient had almost disappeared.

Conclusion: Allium URS is effective in the treatment of hydronephrosis caused by ileal-ureteral anastomotic stenosis. Although complications, such as haematuria, lumbago and urinary tract irritation, are rare, complications, such as stent displacement and stone formation, may occur. Hence, caution must be exercised when considering the use of Allium URSs in the treatment of patients with ileal-ureteral anastomotic stenosis.

Background: This study aims to elucidate the microRNA (miRNA)-messenger RNA (mRNA)-transcription factors (TFs) network relevant to diabetic nephropathy (DN).

Methods: To investigate the molecular mechanisms underlying DN, we conducted an extensive analysis using a Gene Expression Omnibus (GEO) database, specifically GSE51784, GSE30528, GSE30529 and GSE1009. RNA samples from 66 subjects were analysed to identify differentially expressed mRNAs (DEGs) and microRNAs (DEMs) between individuals with DN and healthy controls. The data underwent preprocessing, followed by Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and Gene Set Enrichment Analysis (GSEA) to unveil enriched pathways. Additionally, we constructed protein-protein interaction networks and subnetworks of modules to identify key molecular players.

Results: A total of 163 DEMs and 188 DEGs were identified among the four datasets. Furthermore, we identified 37 hub genes with high connectivity and four TFs, namely E1A Binding Protein P300 (EP300), SP100 Nuclear Antigen (SP100), Nuclear Receptor Subfamily 6 Group A Member 1 (NR6A1) and Jun Dimerization Protein 2 (JDP2), which may play crucial roles in the molecular pathogenesis of DN. Additionally, we constructed a co-regulatory network involving miRNAs, mRNAs and TFs, revealing potential involvement of pathways such as the Mitogen-Activated Protein Kinase (MAPK) signalling pathway, phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt) signalling pathway and metabolic pathways in the pathogenesis of DN. Finally, using a docking model, we established drug-gene interactions involving key genes in the network, providing potential insights into therapeutic options.

Conclusions: This study explores a gene regulation network of miRNA-mRNA-TFs, identifying potential molecular targets in the aetiology of DN. It also suggests potential targets for genetic counselling and prenatal diagnosis for DN.
