OBJECTIVE To elucidate clinicopathologic independent prognostic factors for intravesical recurrence after laparoscopic nephroureterectomy for primary upper urinary tract urothelial carcinoma (UUT-UC). METHODS AND MATERIALS This study included 212 consecutive patients clinically diagnosed as localized UUT-UC and treated by retroperitoneal laparoscopic(More)
BACKGROUND This study compared the efficacy and safety between 120-W thulium:yttrium-aluminum-garnet (Tm:YAG) vapoenucleation of prostates (ThuVEP) and holmium laser enucleation of prostates (HoLEP) for patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). METHODS A retrospective analysis of 88 consecutive patients(More)
BACKGROUND AMP-activated protein kinase (AMPK) is an important enzyme in regulation of cellular energy homeostasis. We have previously shown that AMPK activation by 5-aminoimidazole-4-carboxamide (AICAR) results in suppression of immune responses, indicating the pivotal role of AMPK in immune regulation. However, the cellular mechanism underpinning AMPK(More)
Andrology has a long history in traditional Chinese medicine. There are records of male sexual health, male sexual dysfunction and male infertility from over thousands of years ago. Modern andrology in China had a late start, with the Chinese Andrology Association founded in 1995. Within last decade, andrology in China has grown rapidly. In this review(More)
OBJECTIVE To evaluate the association between vasectomy and prostate cancer. METHODS We searched comprehensively the databases, CBMDisc, CMCC, CMAC, CNKI (from 1978 to January 6, 2009), and PubMed (from 1965 to January 6, 2009) using the key words "vasectomy" and "prostate cancer", screened the retrieved literature according to the inclusion and exclusion(More)
BACKGROUND Ascorbic acid has important antioxidant properties, and may play a role in the protective effects of ischemic preconditioning on later ischemia-reperfusion. Herein, we examined the role of endogenous extracellular ascorbic acid in ischemic preconditioning in the kidney. METHODS We developed a solitary rabbit kidney model where animals received(More)
Inflammatory bowel disease (IBD) is characterized by excessive innate immune cell activation, which is responsible for tissue damage and induction of adaptive immune responses. All-trans retinoic acid (ATRA), the ligand of retinoic acid receptors (RAR), has been previously shown to regulate adaptive immune responses and restore Th17/Treg balance, while its(More)
BACKGROUND The coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma. METHODS A total of 350(More)
OBJECTIVE To investigate the knowledge of and attitude to sexual dysfunction in aged men, and to discuss the status and needs of male healthcare. METHODS Two thousand seven hundred and twenty-eight men (40-70 years old) were surveyed on sexual dysfunction using the randomized questionnaire in Xicheng District, Beijing. RESULTS The prevalence of erectile(More)
Pluronic block copolymers, a kind of non-ionic surfactant, also known as poloxamers, and ultrasound-targeted microbubble destruction have been respectively investigated as vectors for gene delivery in vitro and in vivo. However, they are limited for clinical application due to the relatively low transfer efficiency of each individual vector. In the present(More)
