Abstract

Abstract:

BACKGROUND: Static cold storage is the main storage method of liver transplantation in the past 40 years. There are success cases in foreign countries about the use of mechanical reperfusion in liver transplantation, but there is no large-scale development in China.

OBJECTIVE: To investigate and compare the inflammatory cytokines and apoptotic factors in isolated liver between static cold storage and hypothermic machine perfusion before and after liver transplantation.

METHODS: There were donor group, static cold storage group and hypothermic machine perfusion group in the study, and 30 dogs were in each group. Liver specimens from donor dogs were subjected to static cold storage and then transplanted into dogs in the static cold storage group. Liver specimens from dogs in the static cold storage group were subjected to hypothermic machine perfusion and then transplanted into dogs in the hypothermic machine perfusion group. Liver specimens from dogs in the hypothermic machine perfusion were used in other experiments. Dogs in the donor group were euthanatized. After liver transplantation, 20 dogs from static cold storage group and hypothermic machine perfusion group were selected respectively for further study.

RESULTS AND CONCLUSION: When the liver was separated from the dogs, inflammatory cytokines and apoptosis factors had no significant difference in the static cold storage group and hypothermic machine perfusion group (P > 0.05). P53 expression in these two groups had no significant difference before and after transplantation (P > 0.05). Interleukin-1βand interleukin-8 in these two groups had no significant difference before transplantation (P > 0.05). Compared with the static cold storage group, expressions of tumor necrosis factor-α, macrophage inflammatory protein-1α, macrophage inflammatory protein-1β, CC chemokine ligand 20 and FASR were significantly lower in the hypothermic machine perfusion group before transplantation (P < 0.01). Compared with the static cold storage, interleukin-1β, tumor necrosis factor-α, interleukin-8, macrophage inflammatory protein-1α, macrophage inflammatory protein-1β, CC chemokine ligand 20, FASR and nuclear factor-κB were reduced significantly in the hypothermic machine perfusion group at 60 minutes after transplantation (P < 0.01). Taken together, hypothermic machine perfusion can significantly reduce inflammatory cytokines and apoptosis factor, which is conducive for liver transplantation.
