Emphysematous cystitis (EC) refers to a rare form of complicated urinary tract infection (UTI), which is typically observed in elderly females with severe diabetes mellitus. EC was triggered by bacteria, producing gas filled cysts in the bladder wall and lumen, the most common of which are and . Since EC could be potentially life-threatening, severe form of EC (like septic shock) can cause gangrenous cystitis (GC).

Tumor relapse and metastasis are the major causes of mortality associated with urothelial cancer. In the tumor microenvironment, negative regulatory molecules and various immune cell subtypes suppress antitumor immunity. The inflammatory microenvironment, associated with neutrophils and neutrophil extracellular traps (NETs), promotes tumor metastasis.

Background: The influences of blood lipids and lipid-regulatory medications on the risk of bladder cancer have long been suspected, and previous findings remain controversial. We aimed to assess the causality between blood lipids or lipid-regulatory medications and bladder cancer susceptibility by means of a comprehensive Mendelian Randomization (MR) study.

Methods: Genetic proxies from genome-wide association studies (GWAS) of four blood lipid traits and lipid-lowering variants in genes encoding the targets of lipid-regulatory medications were employed.

Article Synopsis
  • Scientists are studying why some bladder cancer cells can resist a drug called cisplatin, which is used to treat cancer.
  • They found that a protein named MAT2A helps these resistant cancer cells use a substance called methionine to survive.
  • By targeting MAT2A and another protein called SLC7A6, researchers believe it might be possible to make these resistant cancer cells more vulnerable to cisplatin treatment.

Liquid biopsy, as a novel noninvasive tool for biomarker discovery, has gained a lot of attention and represents a significant innovation in precision medicine. Due to its minimally invasive nature, liquid biopsy has fewer complications and can be scheduled more frequently to provide individualized snapshots of the disease at successive time points. This is particularly valuable in providing simultaneous measurements of tumor burden during treatment and early detection of tumor recurrence or drug resistance.

Endoplasmic reticulum membrane protein complex subunit 10 (EMC10) is an evolutionarily conserved and multifunctional factor across species. We previously reported that knockout (KO) leads to mouse male infertility. -null spermatozoa exhibit multiple aspects of dysfunction, including reduced sperm motility.

Our goal was to explore the bioactive constituents of Longsheyangquan (LSYQ) Decoction and elucidate its mechanisms on the treatment of bladder cancer (BCa). A total of 38 compounds were selected based on their pharmacokinetic properties in three large traditional Chinese medicine (TCM) databases. 654 putative targets of LSYQ Decoction were predicted using a structure-based, reverse-docking algorithm online, of which 343 overlapped with BCa-related protein-coding genes.

Bladder cancer (BC) is known as a common and lethal urinary malignancy worldwide. Circular RNAs (circRNAs), an emerging non-coding RNA, participate in carcinogenesis process of several cancers including BC. In this study, high-throughput sequencing and RT-qPCR were applied to discover and validate abnormal high expression of circUBE2K in BC tissues.

Prostate cancer (PCa) is one of the common malignancies in male adults. In the era of precision medicine, many other novel agents targeting advanced prostate cancer, especially metastatic castration-resistant prostate cancer (mCRPC), are currently being evaluated. Among all these candidate therapies, poly-ADP ribose polymerase (PARP) inhibitors targeting DNA damage response (DDR) pathway has proven improving survival outcomes in clinical trials.

Objective: This study was performed to investigate the feasibility of tubularization of the ileal seromuscular fold for long-segmental ureteral reconstruction in a canine model and assess the clinical application of this procedure.

Methods: The experimental study was conducted on six beagles. An ileal segment was chosen and folded along its longitudinal axis and thereafter sutured to tubularize the serous surface.

Background: Penoscrotal extramammary Paget's disease is a rare, slow-growing neoplasm with high frequency of local recurrence.

Aims: The aim of this study was to investigate the difference in clinicopathological characteristics between first-time and recurrent penoscrotal Paget's disease, and to discover the potential risk factors of recurrence.

Methods: Between January 2007 and February 2014, a total of 164 Chinese patients with biopsy-proven tramammary Paget's diseaseex in penis and scrotum underwent wide local resection in our institution.

Article Synopsis
  • * This study highlights EMC10, a protein critical for male fertility, showing that its absence in mice leads to sterility and various sperm defects, including poor motility and abnormal morphology.
  • * Mechanistically, EMC10 helps regulate ion balance in sperm, and its deficiency results in impaired sperm function, indicating that it could serve as a potential biomarker and treatment target for male infertility.

This study was performed to evaluate prostate-specific antigen-age volume (PSA-AV) scores in predicting prostate cancer (PCa) in a Chinese biopsy population. A total of 2355 men who underwent initial prostate biopsy from January 2006 to November 2015 in Huashan Hospital were recruited in the current study. The PSA-AV scores were calculated and assessed together with PSA and PSA density (PSAD) retrospectively.

Background: Reconstruction of ureteral defects and strictures remains problematic for urologists. We aimed to investigate the possibility of a tapered non-vascularized bladder graft as a novel substitute for ureteral reconstruction.

Methods: This experimental study was conducted on nine beagles.

Emerging evidence indicates that aldosterone and mineralocorticoid receptors (MRs) are associated with the pathogenesis of erectile dysfunction. However, the molecular mechanisms remain largely unknown. In this study, freshly isolated penile corpus cavernosum tissue from rats was treated with aldosterone, with or without MRs inhibitors.

Human epidermal growth factor receptor type 2 (HER2) and androgen receptor (AR) are critical factors for prostate cancer (PCa) progression. These factors regulate tumor cell survival and proliferation, and remain as crucial drivers of castration-resistant PCa progression. Icaritin (ICT) is a prenyl flavonoid derived from the Epimedium genus, which has many biological and pharmacological effects.

Objective: The aim of this experimental study was to evaluate the feasibility of a bilateral Boari flap bridge as a novel method for unilateral long-segment ureteral reconstruction.

Materials And Methods: The study was conducted on eight dogs. After resection of 10 cm of right-sided distal ureter, bilateral Boari flaps were made from the anterior upper wall of the bladder and then anastomosed head to head, forming a flap bridge.

The poor quality of initial transurethral resection (TUR) would leave residual tumor and compromise the prognosis. The common therapeutic option is to perform re-TUR, which adds burden to patients. We assumed that cryoablation could be applied as adjuvant therapy combined with TUR, thus lead to maxium tumor control.

The aim of this study was to identify a suitable method for detecting lymph node metastasis of gastric cancer (GCA) by hematoxylin and eosin (HE) and immunohistochemical (IHC) staining. We investigated lymph node metastasis using pan-cytokeratin (CK) and epithelial membrane antigen (EMA) IHC staining in a total of 1,422 lymph nodes from 100 patients who underwent radical gastrectomy between 2007 and 2009. Of 700 intestinal and 722 diffuse type GCA lymph nodes, the metastasis rates were significantly different when using conventional HE staining only or HE supplemented with IHC (P<0.
