Perineal nerve block versus periprostatic block for patients undergoing transperineal prostate biopsy (APROPOS): a prospective, multicentre, randomised controlled study.

Background: We aimed to investigate perineal nerve block versus periprostatic block in pain control for men undergoing a transperineal prostate biopsy.

Methods: In this prospective, randomised, blinded and parallel-group trial, men in six Chinese hospitals with suspected prostate cancer were randomly assigned (1:1) at the point of local anaesthesia to receive a perineal nerve block or periprostatic block and followed by a transperineal prostate biopsy. Centres used their usual biopsy procedure.

Anaesthesia in PROstate Biopsy Pain Obstruction Study: A Study Protocol for a Multicentre Randomised Controlled Study Evaluating the Efficacy of Perineal Nerve Block in Controlling Pain in Patients Undergoing Transperineal Prostate Biopsy.

Transperineal prostate biopsy is as effective as the transrectal biopsy in detecting prostate cancer and has a lower risk of infection. However, concerning the procedural pain of the transperineal route, a higher level of anaesthesia is needed, which prevents this approach from being widely used. Although several methods of local anaesthesia to relieve pain during transperineal biopsy have been described, few well-designed trials have been conducted to assess the efficacy of local anaesthesia.

Greatly Enhanced Faradic Capacities of 3D Porous MnO/G Composites as Lithium-Ion Anodes and Supercapacitors by C-O-Mn Bonding.

Through C-O-Mn bonding, graphene nanosheets are homogeneously dispersed in porous MnO to take full advantages of porous MnO and graphene nanosheets, making the as-formed three-dimensional porous MnO/reduced graphene oxide (rGO) composite exhibit good electrochemical performance. Besides, C-O-Mn bonding is demonstrated to greatly promote the Faradic reactions of the composite, resulting in the enhancement of its real capacity in supercapacitor (SC) electrodes as well as lithium-ion battery (LIB) anodes. By simply fine-tuning the content of graphene (<7 wt %), the composite with 2.

[Cefoxitin plus levofloxacin for prevention of severe infection after transrectal prostate biopsy].

Objective: To evaluate the effect of cefoxitin prophylactic in reducing the incidence of severe infection after transrectal prostate biopsy (TRPB).

Methods: This retrospective study included 155 cases of TRPB with a 5-day administration of oral levofloxacin at 200 mg bid (the control group) and another 167 cases with a 3-day administration of oral levofloxacin at the same dose plus intravenous cefoxitin at 2.0 g 2 hours before TRPB (the experimental group) according to the distribution characteristics of drug-resistance bacteria in our department.

[Circumcision versus the foreskin-deglove plus shaft-fix procedure for phimosis or redundant prepuce in obese adult patients].

Objective: To compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

Methods: Forty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.

UBE3C promotes growth and metastasis of renal cell carcinoma via activating Wnt/β-catenin pathway.

Renal cell carcinoma (RCC) is the most common primary malignancy of the kidney and one of the most lethal genitourinary malignancies. Clear-cell renal cell carcinoma (ccRCC) has an extremely poor prognosis because of a high potential for tumor growth, vascular invasion, metastasis and recurrence. Unfortunately, the mechanism of RCC growth and metastasis is not well understood.

Chrebp regulates the transcriptional activity of androgen receptor in prostate cancer.

Androgen receptor (AR), a member of nuclear hormone receptor, plays an essential role in the initiation and progression of prostate cancer (PCa). In the present study, by way of immunoprecipitation followed by mass spectrometry (IP/MS) system, we found that carbohydrate-responsive element-binding protein (Chrebp), a glucose sensor in normal and cancer cells, interacted with AR in LNCaP cells. The interaction was further confirmed by coimmunoprecipitation analysis.

[Electrocatalytic behavior of diamond electrode for organic pollutant].

The physical and electrochemical behaviors of the boron-doped diamond film electrode prepared by chemical vapor deposition technique were studied. The surface microstructure of the electrode was demonstrated by means of scanning electron microscopy. The electrochemical behaviors of the electrode were investigated using cyclic voltammetry and AC Impedance.
