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 explore continuous renal replacement therapy(CRRT) machine for plasma exchange in critical disease in children.Methods Retrospective study of 8 patients(8 month to 14 years,mean 5.7 years) and 32 plasma exchange treatments,after(adowble) lumen catheter inserted into the subclayian venous,using the Baxter BM25 machine with commercially available plasma filters.Results Five patients(3 ABO-incompatibility in bone marrow transplantation,1 thrombotic thrombocytopaenic purpura TTP,1 sepsis) gained full recovery.One systemic lupus erythematosus(SLE) and 1 sepsis experienced moderate improvement while 1 case of acute disseminated encephalomyelitis failed PE treatment.The average total exchange volume was 80-100 mL/kg,achieved at a blood flow rate of 5-10 mL/(kg?min) and a turnover rate of 60-120 mL/(kg?h) over a 3-hours duration.Thirty-one PE treatments were finished smoothly,one of which experienced the serious complication involving plasma filter.Conclusion Plasma exchange therapy is a safe and effective procedure for severe autoimmune abnormalities and pathogen removal in children.

OBJECTIVE:To explore the ideas for the prescription comment of TCM injections,and provide reference for clini-cal rational use. METHODS:Totally 9 457 prescriptions in PIVAS and 400 hospitalized medical records in our hospital in 2015 were collected. The prescriptions and hospitalized medical records which contained TCM injections were retrospectively commented in aspects of indications,usage and dosage,drug combination,solvent selection and repeat medication,and analysis of typical case. RESULTS:In 2015,there were 2 544 prescriptions(26.90%)in PIVAS and 195 medical records(48.75%)that used TCM injections;the irrational use was mainly inappropriate solvent selection(50.70%),inappropriate usage and dosage(27.00%),inap-propriate indications (10.33%),inappropriate combination therapy (7.51%) and repeat medication (4.46%). CONCLUSIONS:Prescription of TCM injections should be commented with the medical records and individual analyzed;in terms of unreasonable prescriptions and medical records TCM clinical pharmacists should actively intervene unreasonable prescriptions by the bed.
