The efficacy and safety of dutasteride and finasteride in patients with benign prostatic hyperplasia: a systematic review and meta-analysis.

Background: Although the efficacy and safety of monotherapy in the treatment of benign prostatic hyperplasia (BPH) have been established clinically, the efficacy and safety of dutasteride and finasteride have not been compared. The aim was to systematically evaluate the efficacy and safety of the two drugs in the treatment of BPH to provide medical evidence for clinical treatment.

Methods: A search of relevant articles was conducted using the electronic databases PubMed, Embase, Medline, Cochrane Library, China Academic Journals Full-text Database (CJFD), Chinese Science and Technology Journal Database (VIP) and Wanfang Database.

Long non-coding RNA NORAD promotes the prostate cancer cell extracellular vesicle release via microRNA-541-3p-regulated PKM2 to induce bone metastasis of prostate cancer.

Background: Bone metastasis is the leading cause of mortality and reduced quality of life in patients with metastatic prostate cancer (PCa). Long non-coding RNA activated by DNA damage (NORAD) has been observed to have an abnormal expression in various cancers. This article aimed to explore the molecular mechanism underlying the regulatory role of NORAD in bone metastasis of PCa.

Gankyrin is a novel biomarker for disease progression and prognosis of patients with renal cell carcinoma.

Background: In the clinic, how to stratify renal cell carcinoma (RCC) patients with different risks and to accurately predict their prognostic outcome remains a crucial issue. In this study, we assessed the expression and prognostic value of gankyrin in RCC patients.

Methods: The expression of gankyrin was examined in public databases and validated in specimens from two independent centers.

Compositional analysis of various layers of upper urinary tract stones by infrared spectroscopy.

The objective of the present study was to determine the composition of various layers of upper urinary stones and assess the mechanisms of stone nucleation and aggregation. A total of 40 integrated urinary tract stones with a diameter of >0.8 cm were removed from the patients.

[Expression and significance of GFR alpha 1 gene in the recovery spermatogenesis of mice].

Objective: To discuss the expression and significance of glial cell-derived neurotrophic factor (GDFN) receptor alpha 1 gene (GFR alpha 1) in the recovery spermatogenesis of mice.

Methods: Adult Kunming mice were injected intraperitoneally with 2 doses of busulfan (10 mg/kg) 24 days apart so as to establish the recovery spermatogenesis model. Testes were harvested 1 w, 2 w, 3 w, 4 w, 6 w, 8 w and 10 w after the second injection, and normal testes were used as control.
