An ensemble learning model for predicting cancer-specific survival of muscle-invasive bladder cancer patients undergoing bladder preservation therapy.

Background: More muscle-invasive bladder cancer (MIBC) patients are now eligible for bladder-preserving therapy (BPT), underscoring the need for precision medicine. This study aimed to identify prognostic predictors and construct a predictive model among MIBC patients who undergo BPT.

Methods: Data relating to MIBC patients were obtained from the Surveillance, Epidemiology and End Results (SEER) database from 2004 to 2016.

A distinct subset of urothelial cells with enhanced EMT features promotes chemotherapy resistance and cancer recurrence by increasing COL4A1-ITGB1 mediated angiogenesis.

Drug resistance and tumor recurrence remain clinical challenges in the treatment of urothelial carcinoma (UC). However, the underlying mechanism is not fully understood. Here, we performed single-cell RNA sequencing and identified a subset of urothelial cells with epithelial-mesenchymal transition (EMT) features (EMT-UC), which is significantly correlated with chemotherapy resistance and cancer recurrence.

Identification of tumor immunophenotypes associated with immunotherapy response in bladder cancer.

Objectives: This study aims to reveal immunophenotypes associated with immunotherapy response in bladder cancer, identify the signature genes of immune subtypes, and provide new molecular targets for improving immunotherapy response.

Methods: Bladder cancer immunophenotypes were characterized in the bulk RNA sequencing dataset GSE32894 and Imvigor210, and gene expression signatures were established to identify the immunophenotypes. Expression of gene signatures were validated in single-cell RNA sequencing dataset GSE145140 and human proteins expression data source.

Establishment of a risk score model for bladder urothelial carcinoma based on energy metabolism-related genes and their relationships with immune infiltration.

Bladder urothelial carcinoma (BLCA) is a common malignant tumor of the human urinary system, and a large proportion of BLCA patients have a poor prognosis. Therefore, there is an urgent need to find more efficient and sensitive biomarkers for the prognosis of BLCA patients in clinical practice. RNA sequencing (RNA-seq) data and clinical information were obtained from The Cancer Genome Atlas, and 584 energy metabolism-related genes (EMRGs) were obtained from the Reactome pathway database.

A study comparing dusting to basketing for renal stones ≤ 2 cm during flexible ureteroscopy.

Objectives: To compare the dusting efficiency and safety with basketing for treating renal stones ≤ 2 cm during flexible ureteroscopy (fURS).

Materials And Methods: This study included 218 patients with renal stones ≤ 2 cm treated with fURS. Among them, 106 patients underwent dusting, and 112 patients underwent fragmentation with basket extraction.

Long noncoding RNA as a potential diagnostic tool for prostate cancer: a systematic review and meta-analysis.

Purpose: To identify consistently expressed lncRNAs and suitable lncRNAs with high sensitivity and specificity from multiple independent studies as potential biomarkers for PCa diagnostics.

Methods: We searched multiple electronic databases including PubMed, Web of Science, EMBASE, Cochrane Library, CNKI, CQVIP, Wanfang, and CBMdisc for studies published up to July 2022. The quality of the included studies was assessed by two independent reviewers based on the QUADAS-2 tool using Review Manager 5.

Chrysophanol, a main anthraquinone from Rheum palmatum L. (rhubarb), protects against renal fibrosis by suppressing NKD2/NF-κB pathway.

Purpose: Chronic kidney disease (CKD), characterized as renal dysfunction and multi-system damage, has become a serious public health problem with high prevalence and mortality. Rheum palmatum L. (rhubarb) is one of the most widely used Chinese herb with renal protective activity.

Flavonoids from Scutellaria barbata D. Don exert antitumor activity in colorectal cancer through inhibited autophagy and promoted apoptosis via ATF4/sestrin2 pathway.

Purpose: Scutellaria barbata D. Don (SB), mainly containing flavonoids, has been frequently used for cancer treatment. However, little research has investigated the antitumor activity of flavonoids from SB (FSB).

Ethyl Pyruvate Attenuates CaCl2-Induced Tubular Epithelial Cell Injury by Inhibiting Autophagy and Inflammatory Responses.

Background/aims: Nephrolithiasis is one of the most prevalent diseases of the urinary system. Approximately 80% of human kidney stones are composed of calcium oxalate (CaOx), and hypercalciuria is one of the most common metabolic disorders. Emerging evidence indicates that autophagy and inflammatory responses are related to the formation of CaOx nephrolithiasis.

Transurethral bipolar plasmakinetic resection combined with 2 μm continuous wave laser vaporization: a new method for the treatment of large volume benign prostatic hyperplasia.

Objective: The aim of this study was to evaluate the safety and efficiency of transurethral bipolar plasmakinetic resection of the prostate (PKRP) combined with 2 μm laser vaporization in the management of large prostates (>80 mL).

Background Data: The safety and efficiency of transurethral vaporesection of the prostate with benign prostatic hyperplasia (BPH), using a 2 μm laser system, have been verified. However, this method does still not manage large volume prostates efficiently.

A study comparing plasmakinetic enucleation with bipolar plasmakinetic resection of the prostate for benign prostatic hyperplasia.

Background And Purpose: Plasmakinetic enucleation of the prostate (PKEP) has been reported to be a new method for the transurethral management of benign prostatic hyperplasia (BPH). Our objective was to compare the safety and efficiency of PKEP with that of bipolar plasmakinetic resection of the prostate (PKRP) in the management of BPH.

Patients And Methods: A total of 303 patients with lower urinary tract symptoms associated with BPH were included in our study.
