A long-standing observation is that the micturition reflex receives supraspinal descending control. Although one supraspinal nucleus (Barrington's nucleus) is identified as the pontine micturition center, it remains largely unknown whether and how other supraspinal tracts are involved in micturition control. Here, we focused on the role of lumbosacral projecting neurons located in the Locus Coeruleus (LC) in modulating micturition, since previous studies indicated that the LC is involved in controlling bladder contraction.

After spinal cord injury, the upward conduction of the spinal cord is lost, resulting in the loss of micturition control, which manifests as detrusor sphincter dyssynergia and insufficient micturition. Studies have shown that serotonergic axons play important roles in the control of the descending urination tract. In this study, mouse models of moderate spinal cord contusions were established.

To determine the best time to perform EPVL treatment by evaluating the efficacy and safety of active stone extraction in treating residual fragments at different time points after RIRS. All participants had renal or upper ureteral stones preoperatively and still had residual stones after receiving RIRS. They were prospectively randomized into four groups: patients in group A received EPVL 3 days after RIRS; patients in group B received EPVL 7 days after RIRS; patients in group C received EPVL 14 days after RIRS; patients in group D did not receive EPVL after RIRS.

Objectives: To explore characteristics of urinary stone composition in China, and determine the effects of gender, age, body mass index (BMI), stone location, and geographical region on stone composition.

Patients And Methods: We prospectively used Fourier-transform infrared spectroscopy to analyse stones from consecutive patients presenting with new-onset urolithiasis at 46 hospitals in seven geographical areas of China, between 1 June 2010 and 31 May 2015. Chi-squared tests and logistic regression analyses were used to determine associations between stone composition and gender, age, BMI, stone location, and geographical region.

Objective: To evaluate the efficacy and safety of Serenoa repens among patients with benign prostatic hyperplasia (lower urinary tract symptoms/benign prostatic hyperplasia [LUTS/BPH]) in China.

Methods: We conducted a double blind, placebo-controlled study of 354 patients with LUTS/BPH from 19 institutions, to evaluate the efficacy and safety of Serenoa repens. Participants were randomly assigned (1:1) into the Serenoa repens extract (320 mg) or placebo groups for 24 weeks.

Nephrolithiasis is a common urological disease and could be secondary to primary hyperparathyroidism (PHPT). PHPT is traditionally characterised with hypercalcaemia. Recently, a normocalcemic PHPT has been officially recognised at the International Workshops.

The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy.

Background: MicroRNAs (miRNAs) are a class of small non-coding RNAs (18-25 nucleotides) which post-transcriptionally regulate gene expression by negatively regulating the stability or translational efficiency of their target mRNAs. This study aimed to determine the function of miR-154-5p in prostate cancer (PCa) cells and identify the novel molecular targets regulated by miR-154-5p.

Materials And Methods: The effects of forced miR-154-5p expression or E2F transcription factor 5 (E2F5) knockdown on PCa cells were evaluated by cell proliferation, flow cytometry, cell migration and invasion assays as well as by Western blot analysis.

Objective: To assess the efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia (BPH).

Methods: We conducted a multi-centered open clinical study on 165 BPH patients treated with Saw Palmetto Extract Capsules at a dose of 160 mg qd for 12 weeks. At the baseline and after 6 and 12 weeks of medication, we compared the International Prostate Symptom Scores (IPSS), prostate volume, postvoid residual urine volume, urinary flow rate, quality of life scores (QOL), and adverse events between the two groups of patients.

High dose of vitamin C intake could increase urine oxalate excretion and hence the risk of calcium stone formation. We report a case of left ureteral stone in a 9-year-old boy with an extremely high urine oxalate excretion. Besides, he had a habit of taking high-dose supplementation of vitamin C since the age of 3 years.

Purpose: miRNAs can regulate the biological processes, including differentiation, proliferation and apoptosis. DICER and DROSHA are two members of RNase III family, playing pivotal roles in the pathway of miRNAs biogenesis. In this study, we hypothesized that genetic variations of the DICER and DROSHA genes were associated with the bladder cancer risk.

To better understand the toxicity of melamine to humans, the stone composition and urinary metabolic lithogenic factors of rats fed diets containing melamine including the infant's melamine-induced stone composition were studied. Sixty 4-week-old male rats divided into three groups were, respectively, fed diets containing no melamine (control), 0.1% melamine, and 1% melamine for 4 weeks.

Objective: To test whether urinary pH and citrate is associated with ceftriaxone-induced kidney stone formation and if acidified urine could dissolve this kind of stone using an in vitro crystallization model.

Methods: Crystallization was induced by mixing ceftriaxone at the standard therapeutic urinary concentration to artificial urine. The response of different physiological pH and citrate on ceftriaxone-induced crystallization was measured by the depletion ratio of ceftriaxone in the process.

Cyclin D1 (CCND1) is a key protein in regulation of cell cycle at the G1-to-S transition phase and is essential for regulation of cell proliferation, differentiation, and transcriptional control. We hypothesized that the CCND1 G870A polymorphism is associated with risk of bladder cancer. The CCND1 G870A polymorphism was genotyped in a hospital-based case-control study of 402 bladder cancer cases and 402 control subjects using the polymerase chain reaction-restriction fragment length polymorphism method.

Background: High-grade prostatic intraepithelial neoplasia (HGPIN) is the most likely precursor of prostate cancer, but the frequency and timing of epigenetic changes found in prostate carcinogenesis has not been extensively documented.

Methods: Here, we performed a differential proteomic profiling study on the serum of HGPIN and prostate cancer patients. Eleven HGPIN patients were enrolled, their serum protein patterns (2D-electrophoresis and mass spectroscopy) were compared with fifteen prostate cancer patients, and the follow-up study was further performed in the HGPIN patients.
