Clinical efficacy of prostate PI-RADS V2.1 score combined with serum PSA-related indicators in the detection of gray zone prostate cancer.

Purpose: The purpose of this study is to improve the diagnostic accuracy of gray zone prostate cancer evaluation by combining the prostate imaging report and data system version 2.1 (PI-RADS V2.1) score with serum prostate-specific antigen (PSA).

Reduction of Tat-interacting Protein 30 Expression Could be a Prognostic Marker in Bladder Urothelial Cancer.

Background: Tat-interacting protein 30 (TIP30) has been reported to be a tumor suppressor, with reduced or absent expression in various tumors. However, its role in bladder urothelial cancer (BUC) has not been investigated. Therefore, herein, we investigated the expression of TIP30 protein in BUC and normal bladder mucosa and the clinical significance of TIP30 expression in the prognosis of BUC.

[Effects of sildenafil on bladder compliance and endothelin-1 in rabbit model of partial bladder outlet obstruction].

Objective: To explore the effects of sildenafil on bladder compliance and endothelin-1 in the rabbit model of partial bladder outlet obstruction.

Methods: A total of 24 adult male New Zealand white rabbits were randomly divided into group A, group B, group C and group D (n = 6 each). The rabbit model of partial bladder outlet obstruction was established in groups C and D while groups A and B underwent a sham operation.

[Effects and mechanisms of phosphodiesterase type 5 inhibitors on rats with overactive bladder].

Objective: To investigate the effects and the possible mechanistic pathway of phosphodiesterase type 5 (PDE5) inhibitors on rats with overactive bladder.

Methods: A total of 24 adult male spontaneously hypertensive rats (SHRs) were randomly divided into 3 groups: daily lavage group, discontinuous lavage group and blank group (n = 8 each). Daily vardenafil (10 mg×kg(-1)×d(-1)), discontinuous vardenafil (10 mg×kg(-1)×d(-1)) and daily normal saline were administered respectively to 3 groups by lavage.

[Bacterial 16S rRNA genes and expression of IL-1β, TNF-α and IgA in prostate tissues].

Objective: To investigate the role of bacteria in the etiology of chronic prostatitis.

Methods: Complete prostate specimens were obtained at autopsy from 192 organ donors (aged 20 - 38 years old) during 2002 to 2008 who died of non-prostatic diseases. One tissue taken from the peripheral prostatic zone according to McNeal was divided into two pieces.

[Etiology, diagnosis and management of spontaneous per renal hemorrhage].

Objective: To investigate the etiology, diagnosis, and management of spontaneous perirenal hemorrhage (SPH).

Methods: The clinical data of 35 patients, 10 males and 12 females, aged 35.9 (12-77), with the diagnosis of SPH, without history of trauma, anticoagulant use, dialysis, and renal transplantation, were analyzed.

[Preparation, characterization and three way catalytic performance for Pd/CZ/Al2O3 catalyst].

Pd/CZ/Al2O3 catalyst was prepared by impregnating a noble metal solution to the support CZ/Al2O3 which was prefabricated by co-impregnation. The investigation results show that Pd/CZ/Al2O3 has a superior three-way catalytic performance, which is comparable to Pd/CZ for the fresh sample and a better one after thermal ageing. Based on the XRD, BET and TPR characterizations, the internal relationship between catalytic performance, composition and structure was discussed.

Synergistic effect of palladium and oxygen vacancies in the Pd/perovskite catalysts synthesized by the spc method.

A series of oxygen-deficient perovskite-supported palladium catalysts were prepared by the "solid phase crystallization" (spc) method and investigated with XRD, TPR, TPD, TEM, XPS, BET analysis and CO oxidation. It was found that Pd/perovskite catalysts synthesized by the spc method were more active for CO oxidation than the calcined LaCo0.95 Pd0.

[Preparation method of Pd/Ce0.5Zr0.5O2 three-way catalysts].

1% Pd/Ce0.5Zr0.5O2(CZ) catalysts were prepared by deposition-precipitation (DP), mixing (MIX) and conventional impregnation (IMP) methods, and the effects of the preparation methods on the three-way catalytic behaviors were investigated.
