BACKGROUND miR-21 has been recognized as an "onco-microRNA" with the activity of negatively modulating the expression of tumor-suppressor genes. However, its role in prostate cancer (CaP) has not been well-documented. We designed this study to assess the potential function of serum miR-21 in the progression of CaP. METHODS Serum samples of 56 patients,(More)
BACKGROUND Both circulating and urinary miRNAs may represent a potential noninvasive molecular biomarker capable of predicting chronic kidney disease, and, in the present study, we will investigate the serum and urinary levels of miR-155 in patients with nephrolithiasis. METHODS Serum and urinary levels of miR-155 are quantified in 60 patients with(More)
This is a case report of a 67-year-old patient with distant metastasis of prostate cancer to the right ureter which caused hydronephrosis. At the beginning, both of the cytology of the morning urine and imaging findings were consistent with urothelial carcinoma. Nephroureterectomy was subsequently performed. Interestingly, the pathological examination of(More)
The objective of this study was to qualitatively and quantitatively evaluate bovine lactoferrin (bLf) and its stability using a rapid RP-HPLC method. bLf could be rapidly detected within 20 min and quantitated at levels down to 5 µg/mL, and the equation of linearity was y = 86.10x + 178.31 with the correlation coefficient (r(2)) 0.9997. Quantitative data(More)
OBJECTIVE We investigated whether narrow-band imaging (NBI) was superior to white light imaging (WLI) for detecting primary non-muscle invasive bladder cancer (NMIBC) in a randomized imaging sequence modality, as the increased detection rate by NBI maybe result from the "second look" inspection of the bladder. METHODS Between February 2009 and May 2010,(More)
BACKGROUND Multiplex urine-based assay emerged outperforms single biomarker (e.g., prostate-specific antigen, PSA) for predicting prostate cancer (CaP), whereas its combined mode has to be fully optimized. Our aim is to determine whether a strategy of combining gene-based, protein-based, metabolite-based with positive, negative makers in urine could(More)
PURPOSE A novel nomogram using the RENAL ([R]adius maximal diameter in cm, [E]xophytic/endophytic properties, [N]earness of the tumor to the collecting system or sinus in mm, [A]nterior/Posterior, [L]ocation relative to the polar lines and [H]ilar) nephrometry score was developed to predict high grade renal cell carcinoma. It showed good performance in(More)
AIM To investigate whether microRNA-21 was involved in mediating the chemoresistance of prostate cancer cells to docetaxel. METHODS A microarray technique was used to determine the miRNA profile in docetaxel-resistant PC3 cells. Real-time PCR was used to confirm the array results. miR-21 mimics and inhibitors were synthesized and introduced to cells using(More)
BACKGROUND The effects of sorafenib in the treatment of advanced renal cell carcinoma (RCC) have been confirmed in an international collaborative phase III trial. This study aims to confirm similar efficacy and treatment-induced toxicities of sorafenib in the treatment of metastatic RCC in ethnic Chinese patients. METHODS Ninety-eight consecutive and(More)
The skeleton is the most common metastatic organ in patients with prostate cancer (PCa). Non-invasive biomarkers that can facilitate the detection and monitoring of bone metastases are highly desirable. We designed this study to assess the expression patterns of serum miR-141 in patients with bone-metastatic PCa. Serum samples were collected to measure the(More)
