Analysis of Risk Factors for Recurrence after Transurethral Resection of Bladder Tumor in Patients with Non-Muscle Invasive Bladder Cancer: 2-Year Follow-Up Outcomes.

Introduction: The aim was to investigate the risk factors for recurrence after transurethral resection of bladder tumor (TURBT) in patients with non-muscle invasive bladder cancer (NMIBC) and to provide a basis for clinical prevention of recurrence of NMIBC.

Methods: From January 2012 to December 2020, 592 patients with NMIBC who underwent TURBT attending the Second Affiliated Hospital of Xi'an Jiaotong University were retrospectively included in this study. Patients were divided into relapse and relapse-free groups according to whether relapse occurred within 2 years.

Rectifying disorder of extracellular matrix to suppress urethral stricture by protein nanofilm-controlled drug delivery from urinary catheter.

Urethral stricture secondary to urethral injury, afflicting both patients and urologists, is initiated by excessive deposition of extracellular matrix in the submucosal and periurethral tissues. Although various anti-fibrotic drugs have been applied to urethral stricture by irrigation or submucosal injection, their clinical feasibility and effectiveness are limited. Here, to target the pathological state of the extracellular matrix, we design a protein-based nanofilm-controlled drug delivery system and assemble it on the catheter.

Renal Pseudoaneurysms after Flexible Ureteroscopy and Holmium Laser Lithotripsy: A Case Report.

Background: Flexible ureteroscopy (FURS) and holmium laser lithotripsy is considered one of the most minimally invasive and safe surgical methods for the treatment of renal calculi. Renal pseudoaneurysm is a rare complication after FURS holmium laser lithotripsy. We report a case of renal pseudoaneurysm after FURS and holmium laser lithotripsy and review the relevant literature to analyze the possible etiology and summarize the treatment.

Effects of a gamma-secretase inhibitor of notch signalling on transforming growth factor β1-induced urethral fibrosis.

Urethral stricture (US) is a common disorder of the lower urinary tract in men caused by fibrosis. The recurrence rate of US is high; however, there are no effective therapies to prevent or treat urethral fibrosis. The pathogenesis of urethral fibrosis involves myofibroblast activation and excessive extracellular matrix (ECM) deposition.

Down-Regulation of Circular RNA_000926 Attenuates Renal Cell Carcinoma Progression through miRNA-411-Dependent CDH2 Inhibition.

Many studies have recognized that circular RNAs (circRNAs) can be promising targets for renal cell carcinoma (RCC) by acting as competing endogenous RNAs for miRNAs. This study intends to uncover the implication of a novel circRNA, circ_000926 in RCC, and how it affects tumorigenesis. Microarray-based circRNA/gene expression profiling of RCC was used to identify differentially expressed circRNAs/genes in RCC and normal tissues.

Effect of dual mTOR inhibitor on TGFβ1-induced fibrosis in primary human urethral scar fibroblasts.

Background: TGFβ1 and mTOR are considered to play important roles in fibrotic diseases. Rapamycin has been reported to inhibit urethral stricture formation in a rabbit model of urethral fibrosis.

Aim: To evaluate if dual mTOR inhibitor has a superior efficacy compared with rapamycin on inhibiting cell proliferation and collagen expression in human urethral scar fibroblasts (HUSFs).

Rapamycin Inhibits the Growth and Collagen Production of Fibroblasts Derived from Human Urethral Scar Tissue.

Rapamycin can inhibit fibroblast proliferation, collagen accumulation, and urethral stricture in rabbits. Transforming growth factor-beta-1 (TGF-1) signaling, with downstream recruitment of Smad2, is known to promote fibrosis. This study examined the effects of rapamycin on fibroblasts derived from human urethral scar tissue (FHUS) and investigated the possible mechanism with respect to regulation of TGF-1 signaling.

Retroperitoneal Laparoscopic Partial Nephrectomy Versus Radical Nephrectomy for Clinical T1 Renal Hilar Tumor: Comparison of Perioperative Characteristics and Short-Term Functional and Oncologic Outcomes.

Purpose: To present our single-center experience with retroperitoneal laparoscopic partial nephrectomy (LPN) and retroperitoneal laparoscopic radical nephrectomy (LRN) for T1 renal hilar tumors and evaluate which one is better.

Methods: A retrospective review of 63 patients with hilar tumors undergoing retroperitoneal LPN or LRN was performed. The perioperative characteristics, change in estimated glomerular filtration rate (eGFR) from baseline to month 3, and oncologic outcomes were summarized.

Bifunctional monomer magnetic imprinted nanomaterials for selective separation of tetracyclines directly from milk samples.

Novel magnetic molecularly imprinted nanomaterials (DA + BSA-MMIPs) were prepared adopting bovine serum albumin (BSA) and dopamine as bifunctional monomers for the first time. Besides the role of assistant functional monomer, BSA can exclude the proteins with like charges and promote low molecular weight tetracyclines to be adsorbed. Thus, the DA + BSA-MMIPs could fulfil the selective separation of tetracyclines directly from milk samples.

EZH2 enhances the invasive capability of renal cell carcinoma cells via activation of STAT3.

The enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) gene has been recognized to be a proto‑oncogene and to be linked to human malignancies. However, the additional functions of EZH2 in renal cell carcinoma (RCC) are not completely understood. In the present study, a possible role of EZH2 in RCC was identified.

Prepubertal exposure to genistein alleviates di-(2-ethylhexyl) phthalate induced testicular oxidative stress in adult rats.

Di-(2-ethylhexyl) phthalate (DEHP) is the most widely used plastizer in the world and can suppress testosterone production via activation of oxidative stress. Genistein (GEN) is one of the isoflavones ingredients exhibiting weak estrogenic and potentially antioxidative effects. However, study on reproductive effects following prepubertal multiple endocrine disrupters exposure has been lacking.

Docetaxel inhibits urethral stricture formation, an initial study in rabbit model.

Methods: Forty adult New Zealand male rabbits were involved in this study, which were randomly assigned into 3 groups, namely a high dose docetaxel (DH, 0.

Identification of angiogenesis-related miRNAs in a population of patients with renal clear cell carcinoma.

In the present study, we compared the expression of miRNAs and angiogenesis-related genes in the renal tumors and adjacent normal renal tissues of patients with clear cell renal cell carcinoma (ccRCC). The first part of the present study was a preliminary analysis of 4 patients with stage T1a/b ccRCC that measured the levels of angiogenesis and expression of angiogenesis-related genes and miRNAs in the tumors and adjacent normal renal tissues. The second part of this study was an analysis of 30 patients with stage T1, T2 or T3 ccRCC that employed qPCR to characterize expression of angiogenesis-related miRNAs in the tumors and adjacent normal tissues.
