Biotransformation of Abiraterone Into Five Characteristic Metabolites by the Rat Gut Microbiota and Liver Microsomes.

It is well known that the role of gut microbiota in drug metabolism, especially in oral difficult absorbable drugs. Understanding the gut microbiota could enable us to understand drugs in new ways. The purpose of the study was to investigate explore the metabolites of the anti-prostate cancer drug Abiraterone by examining gut microbiota metabolism and hepatic metabolism .

The potential biological effects of quercetin based on pharmacokinetics and multi-targeted mechanism .

Quercetin is a plant-derived polyphenol flavonoid that has been proven to be effective for many diseases. However, the mechanism and metabolism of quercetin remains to be clarified. It achieves a wide range of biological effects through various metabolites, gut microbiota and its metabolites, systemic mediators produced by inflammation and oxidation, as well as by multiple mechanisms.

[Lycopene combined with quercetin and curcumin for chronic prostatitis/chronic pelvic pain syndrome in rats: Effect and mechanism].

Objective: To study the therapeutic effect of lycopene combined with quercetin and curcumin on chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) in rats and its underlying mechanism.

Methods: Thirty-three 6-week-old SD male rats were randomly divided into six groups: normal control (n = 3), CP/CPPS model control (n = 6), quercetin (n= 6), curcumin (n = 6), lycopene (n = 6) and combination therapy (n = 6). CP/CPPS was induced by injection of complete Freund's adjuvant into the ventral lobe of the prostate in the latter five groups of rats.

Feasibility of prostatectomy without prostate biopsy in the era of new imaging technology and minimally invasive techniques.

Background: Routinely, after receiving prostate specific antigen (PSA) testing and digital rectum examination, patients with suspected prostate cancer are required to undergo prostate biopsy. However, the ability of ultrasound-guided prostate biopsy to detect prostate cancer is limited. Nowadays, a variety of diagnostic methods and more sensitive diagnostic methods, such as multi-parameter prostate magnetic resonance imaging (mpMRI) and prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) can be applied clinically.

Quercetin protects against chronic prostatitis in rat model through NF-κB and MAPK signaling pathways.

Background: Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a common disease of urology, of which the pathogenesis and therapy remain to be further elucidated. Quercetin has been reported to improve the symptoms of CP/CPPS patients. We aimed to verify the therapeutic effect of quercetin on CP/CPPS and identify the mechanism responsible for it.

A Retrospective Study Comparing Surgical and Early Oncological Outcomes between Intracorporeal and Extracorporeal Ileal Conduit after Laparoscopic Radical Cystectomy from a Single Center.

Background: Robot-assisted/laparoscopic intracorporeal ileal conduit (ICIC) has been reported in many experienced centers. Whether laparoscopic ICIC is superior to extracorporeal ileal conduit (ECIC) and whether laparoscopic ICIC should be promoted is still controversial. The aim of the study was to compare surgical and early oncological outcomes between patients undergoing laparoscopic radical cystectomy (LRC) with ICIC and ECIC.

[Retropublic extraperitoneal laparoscopic prostatectomy with urethra preservation].

Objective: To explore the feasibility and superiority of retropubic extraperitoneal laparoscopic simple prostatectomy with prostatic urethra preservation to treat large volume benign prostatic hyperplasia(BPH) .

Methods: From January 2006 to August 2009, laparoscopic simple prostatectomy with prostatic urethra preservation was performed in 45 patients with symptomatic BPH,and the age of patients was 70.5+/-7.
