Macrophages are widely distributed innate immune cells that play indispensable roles in the innate and adaptive immune response to pathogens and in-tissue homeostasis. Macrophages can be activated by a variety of stimuli and polarized to functionally different phenotypes. Two distinct subsets of macrophages have been proposed, including classically(More)
The SDF-1/CXCR4 axis is critical for inducing stem cell mobilization into the circulation, for homing stem cells to the site of injury, and for stem cell participation in the regeneration of liver tissue. In this study, we have gained insight into the molecular mechanisms involved in regulating the expression of SDF-1α by miRNAs. Using microarray and(More)
Heparanase is an endoglycosidase that degrades heparan sulfate, the main polysaccharide constituent of the extracellular matrix and basement membrane. The expression of heparanase is associated with invasion, as well as the angiogenic and metastatic potential of diverse malignant tumors. We used RNA interference(More)
OBJECTIVES Severe viral hepatitis B is a disease associated with significant morbidity and mortality. Clinical controlled trials show that the efficacy of treatment of severe viral hepatitis B with glucocorticoids remains debatable. Therefore, we carried out this meta-analysis to evaluate the safety, efficacy, and side effects of glucocorticoid therapy for(More)
microRNAs (miRNAs) are short non-coding RNA sequences that play important roles in the regulation of gene expression. They have significant regulatory functions in basic cellular processes, including differentiation, proliferation and apoptosis. miRNAs are differentially expressed in tumors, compared with normal tissues. Importantly, miRNAs are also stable(More)
Human telomerase reverse transcriptase (hTERT) has been identified as a major protein involved in aberrant cell proliferation, immortalization, metastasis and stemness maintenance in a majority of tumors, yet it has little or no expression in normal somatic cells. During the past few years, the development of hTERT-based(More)
Blood donor recruitment models have changed from paid donors to employer-organized donors and to voluntary donors in China. Reports on the hepatitis C virus (HCV) infection among voluntary blood donors in China have been rarely found at present. The prevalence of anti-HCV and genotypes among the first-time voluntary blood donors was investigated in(More)
Inflammatory response plays an important role not only in the normal physiology but also in the pathology such as atherosclerosis. Meprin, an astacin metalloproteinase, has exhibited proinflammatory effects in vivo and in vitro studies. Here, we tried to further investigate the proinflammatory potential of meprin-β and the possible underlying mechanisms in(More)
Previous studies have indicated that heparanase (Hpa) might represent a candidate universal tumor-associated antigen. However, vaccine therapy targeting only one cytotoxic T lymphocyte (CTL) epitope is suboptimal in preventing cancer. In the present study, we designed heparanase multi-epitope vaccines to increase the immune response to standard single(More)
BACKGROUND Accurate and reliable blood grouping is essential for safe blood transfusion. However, conventional methods are qualitative and use only single-antigen detection. We overcame these limitations by developing a simple, quantitative, and multiplexed detection method for blood grouping using quantum dots (QDs) and magnetic beads. METHODS In the QD(More)
