ABSTRACT
OBJECTIVE@#To explore the mechanism by which fractalkine (CX3CL1; FKN) inhibits lipopolysaccharide (LPS)-induced immunological response in RAW264.7 cells.@*METHODS@#A RAW264.7 cell model overexpressing FKN was established by transfection with the lentiviral vector CX3CL1. The effects of LPS, ICG-001 (a Wnt/β-catenin signaling pathway inhibitor), either alone or in combination, on M1 polarization of na?ve and FKN-overexpressing RAW264.7 cells were evaluated by detecting of intereukin-6 (IL-6) and tumor necrosis factor-α (TNF-@*RESULTS@#The RAW264.7 cell model of FKN overexpression was successfully established. In na?ve RAW264.7 cells, treatment with both ICG-001 and LPS, as compared with LPS alone, significant promoted TNF-@*CONCLUSIONS@#FKN overexpression suppresses LPS-induced M1 type polarization of RAW264.7 cells by activating Wnt/β-catenin signaling pathway.

Pharmacology , pharmacokinetics , clinical study and safety of enzalutamide in the treatment of castration-resistant pros-tate cancer (CRPC) were reviewed in the paper.Enzalutamide, a pure second-generation androgen receptor antagonist , can inhibit multiple points in the androgen receptor signaling pathway , including the inhibition of androgen binding to the androgens receptor , nu-clear translocation of the androgens receptor complex and binding of the androgens receptor complex to deoxyribonucleix acid ( DNA) . The phase 3 clinical trials have revealed that enzalutamide is effective to delay the progression of metastatic CRPC , reduce the prostate-specific antigen (PSA) levels, decrease the progression time of PSA and prolong the overall survival time and the time of first skeletal -related events .Enzalutamide has become a novel treatment option for CRPC patients .Enzalutamide is well tolerated with low incidence of side effects .
ABSTRACT
Objective To investigate the association between prenatal monitoring index in intrahepatic cholestasis of pregnancy and the perinatal prognosis,as well as the characteristics of perinatal situations.Methods A retrospective study on the clinical data of 88 cases intrahepatic cholestasis of pregnancy and prognosis that were treated in our hospital from Jan.2011 to Jan.2014 was carried out.Relationship between prenatal monitoring index in intrahepatic cholestasis of pregnancy and perinatal prognosis,together with the epidemiological features of infants were analyzed.Results The incidence rates of perinatal meconium stained amniotic fluid,asphyxia neonatorum,premature and fetal distress were significantly higher in the study group than those in the controls,with differences statistically significant (P＜0.05).The levels of CG,ALT,AST,TBIL,DBIL and TBA in puerperant with bad perinatal situation were significantly higher than puerperant with good perinatal situation,with the difference statistically significant (P＜0.05).Results from the multiple regression analysis indicated that close relations did exist between CG,ALT,AST,TBIL,TBA and adverse perinatal prognosis.The main perinatal risks were related to meconium stained amniotic fluid (33.3％),prematurity (28.6％),fetal distress (20.6％),asphyxia neonatorum (15.9％) and stillbirth (1.6％).Conclusion The rate of adverse perinatal prognosis was low in intrahepatic cholestasis of pregnancy,with most frequently seen as meconium stained amniotic fluid.It was necessary to monitor the level of prenatal CG,ALT,AST,TBIL and TBA in puerperant in predicting the perinatal prognosis.
