Roles of phosphatidylethanolamine-binding protein in cell signaling and its biological functions / 生理学报

Phosphatidylethanolamine-binding protein (PEBP) is a cytoplasm soluble protein with a high conserved structure. It has been approved recently that PEBP is a multifunctional molecule regulating several important cellular signal pathways, including ERK cascade, NF-κB pathway, and signaling of G protein-coupled receptors. Furthermore, the role of PEBP in tumor metastasis also got a comprehensive attention in the field of clinical cancer research. Together, as a signal regulator at multiple paths in cell, PEBP is becoming a new focus in several research fields. This review is aimed to introduce the newest biological progress on PEBP.

Clinical analysis of cytomegalovirus infection after allogeneic hematopoietic stem cell transplantation / 中国实验血液学杂志

The objective of this study was to explore the incidence and therapeutic efficacy of cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The clinical data of 140 patients undergoing allo-HSCT in our department of hematology from 2010-01 to 2012-01 were retrospectively analyzed. The results showed that the incidence of CMV infection was 4.3% (48/140), the time for the first detection of positive CMV-DNA was at day 45 (33 to 68) after allo-HSCT, and the CMV quantitative range was 1.25×10(3) - 5.5×10(6). There were 2 cases of CMV-related interstitial pneumonia and 5 cases of hemorrhagic bladder inflammation. A total of 65 patients suffered from graft versus host disease (GVHD), in which 32 cases (49.2%) were accompanied with CMV infection, CMV-DNA negative in patients treated with ganciclovir, foscarnet sodium anti-CMV was at day 45 (33 to 68) with the effective rate of 100%. 12 patients with CMV infection were accompanied with transient neutropenia and thrombocytopenia. It is concluded that after allo-HSCT the CMV infection occurs frequently. The patients with GVHD have a higher incidence of CMV infection. Ganciclovir and foscarnet sodium are reliable to be used for treatment of CMV infection with fewer adverse reactions.
