Circumcision Status and Risk of HIV Acquisition during Heterosexual Intercourse for Both Males and Females: A Meta-Analysis.

In this study, we evaluated if male circumcision was associated with lower HIV acquisition for HIV (-) males and HIV (-) females during normal sexual behavior. We performed a systematic literature search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify studies that compared HIV acquisition for the circumcised and uncircumcised groups. The reference lists of the included and excluded studies were also screened.

[Bladder reconstruction using autologous bone marrow mesenchyaml stem cells-seeded bladder acellelar matrix graft in a canine model].

Objective: To investigate the feasibility of autologous bone marrow mesenchymal stem cells(BMSCs) seeded on bladder acellular matrix graft (BAMG) for bladder reconstruction in a canine model.

Methods: This study included 25 mongrel dogs. Five dogs were sacrificed for the preparation of BAMG.

Retroperitoneal laparoscopic management method of Castleman's disease in the adrenal gland: two cases report and review of the literature.

Purpose: Castleman's disease (CD) is a rare and complex disease of lymphoid tissues typically involving a mediastinal mass. CD in the adrenal area is an even rarer occurrence. In the present study, two extremely rare cases of adrenal Castleman's disease at our hospital are reported, and the relevant literatures were reviewed.

[Rapid determination of ractopamine content in pork by using three-dimensional synchronous fluorescence spectrum coupled with APTLD].

In order to realize the rapid determination of ractopamine content in pork, quantitative determination model of ractopamine content in pork was established by using three-dimensional synchronous fluorescence spectrum coupled with alternating penalty trilinear decomposition (APTLD). Firstly, the generation mechanism of the fluorescence spectrum for ractopamine and three-dimensional synchronous fluorescence spectrum for samples were analyzed. Secondly, concentration quenching phenomenon of fluorescence of ractopamine in pork extract was investigated.

Bipolar transurethral resection versus monopolar transurethral resection for benign prostatic hypertrophy: a systematic review and meta-analysis.

Purpose: To evaluate the efficacy and safety of monopolar (M-TURP) and bipolar (B-TURP) transurethral resection of the prostate in benign prostatic hypertrophy (BPH) patients.

Materials And Methods: Eligible randomized controlled trials (RCTs) were identified from electronic databases without language restrictions. Database search, quality assessment, and data extraction were independently performed.

[Rapid determination of tetracycline content in duck meat using particle swarm optimization algorithm and synchronous fluorescence spectrum].

Tetracycline under the condition of NaOH could be degraded to iso tetracycline which has strong fluorescent characteristic, and the prediction model of tetracycline contents in duck meat was developed with the combination of synchronous fluorescence spectrum, wavelet de-noising, particle swarm optimization algorithm (PSO) and support vector regression (SVR), and it could realize the rapid prediction of tetracycline contents in duck meat and improve the accuracy of prediction model. In the process, 70 nm was selected as the optimum wavelength difference for the determination of tetracycline contents in duck meat by using parallel factor analysis (PARAFAC). Secondly, the db6 wavelet with 2 levels decomposition was used to reduce the noise of synchronous fluorescence spectrum, and the spectrum after wavelet de-noising was normalized, and 6 characteristic wavelengths were selected by using PSO.

Mixed epithelial and stromal tumor of the kidney.

A 44-year-old woman who underwent radical nephrectomy due to a left renal mass presented to our clinic. Results of the histopathological examination showed a mixed epithelial and stromal tumor of the kidney, a rare benign lesion of the kidney. The epidemiology, histopathological features, imaging features, possible pathogeneses, and treatment alternatives are discussed, and the relevant literature is reviewed.

Tamsulosin as adjunctive treatment after shockwave lithotripsy in patients with upper urinary tract stones: a systematic review and meta-analysis.

Objective: This study aimed to evaluate the efficacy of tamsulosin as an α(1)-blocker in the treatment of the renal and ureteral stones after shockwave lithotripsy (SWL).

Material And Methods: Relevant randomized controlled trials were identified by electronic and document searches of MEDLINE, EMBASE, the Chinese Biomedical Disk and the Cochrane Central Register of Controlled Trials until April 2010. No language restriction was applied.
