The anoikis resistance confers the ability of cancer cells to survive and metastasize in the blood circulation without adhesion,but its effect and mechanism in intrahepatic and distant metastasis of hepatocellular carcinoma has not been fully elucidated.Recent studies have shown that certain factors or drugs may inhibit anoikis of hepatoma cells through some signaling pathways.These signaling pathways are not completely separated,they are interconnected to promote metastasis of hepatocellular carcinoma.Liver is the metabolic center of many substances,and many related factors can promote metastasis of hepatocellular carcinoma through inhibiting anoikis.In this review,we summarized the signaling pathways of anoikis resistance of hepatocellular carcinoma.

Primary sclerosing cholangitis (PSC) is a common autoimmune liver disease,and the diversity of its treatment methods has been hotly discussed by scholars in various countries.As the best treatment,end-stage liver transplantation (LT),due to the related diseases,such as postoperative complications greatly limits its wide application in clinical practice.Early assessment and intervention can reduce the risk of concomitant disease and reduce the occurrence of postoperative complications.In this paper,the status of LT indications,timing and related disease management,postoperative complications and other aspects of PSC patients were reviewed.

Objective:To explore the changes of blood viscosity in high-intensity alternating magnetic field and the mechanisms.Methods:Five adult sheep were randomly selected and the blood samples were placed in highintensity alternating magnetic field.Before and after exposure,the blood samples were taken and divided into 2 groups:a control group and a magnetic field group.The blood rheology and transmission electron microscopy (TEM) were performed.Results:Compared to the control group,the high shear viscosity of whole blood was decreased in the magnetic field group (P＜0.05);the whole blood low shear viscosity and plasma viscosity were also decreased (both P＜0.01).TEM showed the changes in red blood cell morphology and the double concave disc curvature.The radian of double concave disc and cell volume in the magnetic field group was larger than those in the control group.Conclusion:The high intensity alternating magnetic field may affect the distribution of surface charge and molecular current in blood cells,which in turn decrease the aggregation of cells and the blood viscosity.
