BACKGROUND The control of nosocomial transmission of methicillin-resistant Staphylococcus aureus (MRSA) represents a significant challenge to infection control professionals. Nasal carriage colonization by MRSA plays a crucial role in the epidemiology and pathogenesis of this infection. METHODS Patients in the medical intensive care unit (ICU) between(More)
Anti-TNF-α therapies have been applied in RA treatment, but the regulatory effect of the drug on immune system is not clear. In this study, we included 33 active RA patients and divided them into two groups. One group received anti-TNF-α mAb+methotrexate for 24 weeks, the other group got placebo+methotrexate for the first 12 weeks and anti-TNF-α(More)
Bone disease is a common clinical problem after kidney transplantation. To date, studies investigating the effects of tacrolimus (TAC) on bone metabolism in vivo or vitro yielded conflicting data. This study was carried out to discuss the relationship between TAC blood concentrations and bone metabolism status in kidney transplant recipients. 72 kidney(More)
Results from studies on the association of PTPN22 C1858T polymorphism with AITD risk are conflicting, we thereby perform this meta-analysis to derive a more precise effect on this possible association. Two investigators independently searched the PubMed, Embase, Wanfang and CNKI (China National Knowledge Infrastructure) databases. A total of 11 studies(More)
NAD(P)H:quinone oxidoreductase 1 (NQO1) is a cytosolic flavoprotein that catalyzes the two-electron reduction of quinoid compounds into hydroquinones, thus protecting cells from oxidative damage. A single base substitution (C→T) polymorphism at 609 in the NQO1 gene reduces quinone reductase activity. Thus, the lack of enzymatic activity in the homozygous(More)
Caspase (CASP) 3 is an important caspase in the apoptosis pathway and plays an important role in the development and progression of cancer. We hypothesized that genetic variants in CASP 3 may modify individual susceptibility to hepatocellular carcinoma (HCC). Five hundred HCC cases in West China Hospital were selected, and 500 healthy cases with the same(More)
P73, a p53 homolog, has some p53-like activities and plays an important role in modulating cell cycle, apoptosis, and DNA repair. A potentially functional dinucleotide polymorphism, G4C14-to-A4T14, has been identified in the 5′ untranslated region of exon 2 of the p73 gene, which may theoretically form a stem-loop structure and affect gene expression. We(More)
OBJECTIVE Chronic hepatitis B (CHB) affects 400 million people and is the most common cause of liver cirrhosis (LC) and hepatocellular carcinoma (HCC) worldwide. Cellular immune regulation plays an important role in determining the infection outcome. Co-signal molecules and Th17/Treg were studied to explore their association with the progression of HBV(More)
The parallel FDTD method based on MPI is studied on High-Performance Computer Clusters. This paper proposed several key aspects involved in the parallel computation of the FDTD. Results of a numerical example of a trihedral corner reflector, which divided the computing space to N×M×P (N,M,P≥3) sub-domains, demonstrate the validity of the(More)
This paper aims to observe and analyze effects of Codonopsis pilosula water extract on micro RNA (miRNA) expression profile in liver tissue of senile mice. The 110 Konminmice were randomly divided into five groups, including D-galactose-induced senile model group, normal control group, and low, middle and high dose intervention groups. Continuous modeling(More)
