Objective To investigate the etiological factors of hepatic dysfunction during late gestational period,and explore its effect on the mothers and babies.Methods The causes and prognosis of 347 cases with hepatic dysfunction during gestational period were retrospectively analyzed.Result Of the 347 cases of pregnancy,viral hepatitis was present in 216 cases(62.2%),and intrahepatic cholestasis of pregnancy(ICP) present in 80 cases(23.1%);Postpartum hemorrhage rate increased significantly in viral hepatitis,and the rates of premature birth,fetal distress in uterus and cesarean increased obviously in ICP.Conclusion Viral hepatitis and ICP were the main causes of hepatic dysfunction,different complicated diseases may increase the danger of the mother and baby during pregnancy and childbirth.

Objective To study the relationship between liver histological changes and expression of HBcAg in peripheral blood dendritic cells in patients with chronic hepatitis B.Methods The peripheral blood samples were obtained from 24 patients with chronic hepatitis B (CHB) and 8 healthy individuals.The peripheral blood mononuclear cells (PBMCs) were isolated.DCs were isolated from peripheral blood mononuclear cells and enriched by culturing with recombinant human interleukin 4(rhIL-4) and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF),then DCs were harvested and the costimulators of CD80,CD86,CD40 and CD54 on DCs were tested by immunofluorescence flow cytometry.These costimulators were compared with liver histological changes.Results Percentage of CD40 and CD86 was significant lower than that of healthy donors(P
