A liquid chromatography/tandem mass spectrometry (LC-MS/MS) method was developed and validated for determining tacrolimus (FK506) in rat tissues to study the effect of Schisandra sphenanthera extract on FK506 tissue distribution. After a liquid-liquid extraction with ethyl acetate, FK506 and ascomycin (IS) were subjected to LC-MS/MS analysis using positive(More)
BACKGROUND We combined the outcomes of all randomised controlled trials to investigate the safety and efficacy of steroid avoidance or withdrawal (SAW) regimens in paediatric kidney transplantation compared with steroid-based (SB) regimens. METHODS A systematic literature search of PubMed, Embase, Cochrane Library, the trials registry and BIOSIS previews(More)
AIM Extracts of Tripterygium wilfordii Hook F. have been used to treat glomerulonephritis for more than 30 years in China. Most of the anti-inflammatory and immunosuppressive activities of these extracts can be attributed to triptolide (Trip). The present study was to investigate the effect of Trip on renal interstitial fibrosis in a model of unilateral(More)
BACKGROUND/AIMS While there are drug exposure equation models based on limited sampling times for mycophenolate mofetil (MMF), there are few for enteric-coated mycophenolate sodium (EC-MPS), and none that studied Chinese individuals. Our objective is to generate the optimal model equations for estimation of the mycophenolic acid (MPA) area under the plasma(More)
AIM Co-administration of diltiazem can reduce the dosage of cyclosporine (CsA) in patients with renal transplantation. In this study, we investigated how diltiazem altered the relationship between MDR1 genetic polymorphisms and CsA concentration in Chinese patients with renal transplantation. METHODS A total of 126 renal transplant patients were enrolled.(More)
BACKGROUND The dramatic growth of mobile phone (MP) use among young people has increased interest in its possible health hazards in this age group. The aim of this cross-sectional study was to investigate the association between MP use and inattention in adolescents. METHODS A total of 7720 middle school students were involved in this cross-sectional(More)
BACKGROUND Kidney transplantation (KTx) is the primary therapy for children with renal failure. Unlike KTx in adult patients, it is commonly agreed that pediatric KTx in China is far behind that of America. There has been no systematic analysis of Chinese pediatric KTx reported. This study aimed to demonstrate the current status of pediatric KTx in China.(More)
OBJECTIVES To review the retrospective treatment results of the azoospermia patients during January 2001 to January 2002 in the fertility center. METHODS One hundred males attempted intracytoplasmic sperm injection (ICSI) cycle for treatment of azoospermia. All patients were undergone sperm retrieval by percutaneous epididymal sperm aspiration (PESA) or(More)
BACKGROUND Simultaneous liver and kidney transplantation (SLKT) has been proven to be a favorable treatment for combined renal and hepatic end-stage disease. However, recipients receiving SLKT have a long medical history, poor general condition that is often accompanied by anemia, hypoalbuminemia, coagulopathy, water-electrolyte imbalance and acid-base(More)
BACKGROUND Elderly patients with end-stage renal disease have become the fastest growing population of kidney transplant candidates in recent years. However, the risk factors associated with long-term outcomes in these patients remain unclear. METHODS We retrospectively analyzed 166 recipients aged 60 years or older who underwent primary deceased kidney(More)
