For patients lacking a human leucocyte antigen-matched donor, umbilical cord blood (UCB) is an ideal, alternative source of haematopoietic stem cells (HSCs) for transplantation purposes. UCB has many advantages over bone marrow or peripheral blood taken from volunteer donors. UCB is also an important source of other stem cells, including endothelial progenitors, mesenchymal stem cells, very small embryonic/epiblast-like (VSEL) stem cells, and unrestricted somatic stem cells, which are potentially suitable for regenerative medicine. However, a significant clinical problem is that the number of HSCs in one cord-blood unit is not enough for an adult transplantation. The development of new approaches including use of multiple donors, ex vivo expansion, increasing efficiency of homing and engraftment, retrieving more cells from the placenta and cord blood is of crucial importance for the delayed engraftment after UCB transplantation. In the future, UCB will emerge as a source of cells for cellular therapies associated with tissue repair and regeneration. © 2013 International Federation for Cell Biology.

Alzheimer's disease (AD) is a neurodegenerative disorder characteristic of neurons reducing, senile plaques, neurofibrillary tangles and so on, and the most common cause of dementia among the elderly. Many efforts have been made to understand the epigenetic mechanisms involved in the development of AD, such as gene methylation and histone acetylation, although the exact mechanisms are not yet entirely clear. Here, we provide a review of the epigenetic mechanisms and related research in AD, which may provide a new direction for the research as well as the development of the epigenetic drugs.

Background: Insulin resistance is a key element in the pathogenesis of type 2 diabetes mellitus. Plasma free fatty acids were assumed to mediate the insulin resistance, while the relationship between lipid and glucose disposal remains to be demonstrated across liver, skeletal muscle and blood. Methods. We profiled both lipidomics and gene expression of 144 total peripheral blood samples, 84 from patients with T2D and 60 from healthy controls. Then, factor and partial least squares models were used to perform a combined analysis of lipidomics and gene expression profiles to uncover the bioprocesses that are associated with lipidomic profiles in type 2 diabetes. Results: According to factor analysis of the lipidomic profile, several species of lipids were found to be correlated with different phenotypes, including diabetes-related C23:2CE, C23:3CE, C23:4CE, ePE36:4, ePE36:5, ePE36:6; race-related (African-American) PI36:1; and sex-related PE34:1 and LPC18:2. The major variance of gene expression profile was not caused by known factors and no significant difference can be directly derived from differential gene expression profile. However, the combination of lipidomic and gene expression analyses allows us to reveal the correlation between the altered lipid profile with significantly enriched pathways, such as one carbon pool by folate, arachidonic acid metabolism, insulin signaling pathway, amino sugar and nucleotide sugar metabolism, propanoate metabolism, and starch and sucrose metabolism. The genes in these pathways showed a good capability to classify diabetes samples. Conclusion: Combined analysis of gene expression and lipidomic profiling reveals type 2 diabetes-associated lipid species and enriched biological pathways in peripheral blood, while gene expression profile does not show direct correlation. Our findings provide a new clue to better understand the mechanism of disordered lipid metabolism in association with type 2 diabetes. © 2013 Zhao et al.; licensee BioMed Central Ltd.

Objective To explore the correlation between the degree of target vessel occlusion and in-hospital mortality in patients with acute ST-elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). Methods To retrospectively analyze the data collected from the Management System of Cardiovascular Interventional Treatment in Military Hospitals. A total of 8170 patients with STEMI and PCI were enrolled, and the endpoint of present study was in-hospital mortality. The degree of target vessel occlusion were stratified to determine the effects of occlusion degree on in-hospital mortality. Results According to the degree of target vessel occlusion, the enrolled patients were divided into 2 groups: 75%-99% occlusion group and 100% occlusion group. The in-hospital mortality in the 2 groups were 2.2% and 3.0%, respectively (P=0.077). The patients were then further divided into 3 groups according to the symptom-onset-to-balloon time <3h, between 3h and 6h, and ≥6h. The in-hospital mortality in duration <3h group were 2.5% and 3.3%, respectively (P=0.436); duration between 3h and 6h group were 2.0% and 2.9%, respectively (P=0.147); and duration ≥6h group were 2.4% and 2.8%, respectively (P=0.430). Conclusion The in-hospital mortality in STEMI patients may be no relation with the degree of target vessel occlusion. © 2016, People’s Military Medical Press. All rights reserved.
