Myeloid differentiation protein-2(MD-2)can separately and simultaneously bind lipopolysaccharide(LPS)and toll-like receptor 4(TLR4)has been shown to play critical roles in mediated recognition responses to LPS by TLR4 and signal transduction induced by LPS.MD-2 can be bound by LPS,not TLR4.The cells have no responsiveness or weak responsiveness to LPS without MD-2.MD-2 can be secreted into blood plasma,formed soluble MD-2 and remotely regulated cells that contained TLR4 without MD-2.MD-2 has been shown to play important roles in endotoxin signal transduction.MD-2 is a small molecular,short nucleic acid fragment,easily regulated should become a new potential anti-inflammatory target.

Objective To investigate the impact of alterations within the space of Disse micro- environment on the migration of hepatic stellate cells(HSC) during the process of liver fibrosis,and to ex plore the novel mechanism of liver fibrosis from the view of cell migration.Methods A modified in vitro Boyden chamber system to partially mimic in vivo microenvironment of Disse space of normal and liver fibrosis was employed.The effects of fibrogenetic growth factors on the migration of HSC in liver fibrosis were observed via cell migration and cell proliferation experiments.Results Enhanced platelet-derived growth factor(PDGF)-BB,transforming growth factor(TGF)-?1 and/or epithelial growth factor(EGF) in liver fibrosis resulted in an increase in migratory capacity of activated HSC.The enhanced migration of HSCs induced by PDGF-BB was partially associated with their increased proliferation,while,TGF-?1 or EGF-induced migration was proliferation independent.The elevation of basic fibroblast growth factor (bFGF) or vascular endothelial growth factor(VEGF)during liver fibrosis had no effect on the migration of HSCs.Conclusions The study provides valuable insights into the role of space of Disse microenvironment in regulating HSC migratory behavior.TGF-?1,PDGF-BB and EGF,which increased in liver fibrosis, could induce the migration of activated HSC.However,bFGF or VEGF has no such kind of effect,al- though they also increased during liver fibrosis.

Objective To integrate nurses' humanistic quality into professional nursing training, in order to improve humanistic quality and nursing quality. Methods Nurses with working years within 6 years in our hospital were chosen from May, 2009 to May, 2010. And through non-professional reading, specified materials reading, multimedia lectures, particularly the refining and essence of reading reports, humanities knowledge and humanistic care consciousness was melted into personal morality, words, deeds and cultivation. Investigation about satisfaction degree was carried out among patients before and after the training. Results Satisfaction degree of patients increased after training, so did the satisfaction degree of nurses to reading reports. Conclusions To integrate nurses' humanistic quality into professional nursing training can improve humanistic quality of nurses and nursing quality. Nurses' professional image will be increasingly standard, overall quality and service quality can be improved, and thought of dedicated service for patients will be consolidated.
