ObjectiveTo investigate the establishment of a rat model of orthotopic liver transplantation with more complete and easier performance of graft perfusion and easier control of warm ischemic time. MethodsA modification of Kamada two-cuff method was used. Cold perfusion of donor livers was done through the (ascending) aorta. Suture anastomosis of suprahepatic vena cava was performed. Infrahepatic vena cava and (portal) vein anastomoses were done by the cuff technique. The bile duct was anastomosed with internal stent. The non-heart-beating donor(NHBD) graft model of orthotopic liver transplantation in rats was thus (established).ResultsThe survival rate of recipients grafted from NHBD with perfusion of ascending aorta was 95% (38/40) for 1 day and 85.5% (35/40) for 7 days. ConclusionsThe livers of NHBD as grafts harvested with perfusion through ascending aorta had more complete and homogeneous perfusion, perfusion was easier to perform and warm ischemia time was more accurately controlled. The one-week posttransplantion (survival) rate was longer than that reported in the literature.

Enhanced recovery after surgery (ERAS)is a new concept of accelerating the recovery of patients through a series of multi-mode strategies based on evidence-based medicine date in perioperative period. The perioperative fluid therapy is an important part of ERAS, including three phases of preoperative、intraoperative and postoperative. Its aim is to maintain the circulation volume to ensure circulation stability and effective perfusion of tissues, to avoid tissue ischemia and hypoxia, and to reduce surgical stress, maintain internal environment stability, reduce postoperative respiratory and circulatory complications, thus accelerating recovery. Fluid therapy has been controversial, Goal-directed Fluid Therapy is a recognized method.This article reviews the latest advances in preoperative, intraoperative and postoperative fluid therapy on the guidance of ERAS and its influence on postoperative outcomes.

Objective To compare the contents in polysaccharide of aloe in gel of aloe with preparation in different processing methods on fresh aloe of outer cuticle and investigate their stability. It could provide technology of preparation of polysaccharide of aloe.Methods The aloe gel had been prepared through the fresh juicing method, and alcohol sinking was applied to abstract polysaccharides of aloe in proportion of sixty, seventy, eighty and ninety percent. The colorimetric method of anthracenone - thick sulfuric acid had been taken to determine contents of polysaccharide in different proportions by alcohol sinking. The contents of polysaccharide were compared among different processing methods in fresh aloe of outer cuticle, and then the stability on condition of different temperatures, pH and the reagent of reductant-oxidant with polysaccharides of aloe were investigated. Results The content abstracted from polysaccharide of aloe was the higher when the proportion was eighty percent and its character of powder was better. And content abstracted from polysaccharide of aloe with the outer cuticle was higher than that out of the outer cuticle. The powders from the polysaccharide of aloe with the outer cuticle were gray-green, gray-brown or gray-white. The powders from polysaccharide of aloe without the outer cuticle were partial-white, more well-distributed and delicate. The stability in polysaccharide of aloe was better with the condition of low temperature, reducing agent and the solution with pH from five to seven, while the stability was lower when in high temperature, oxidizing agent and the solution with strong acid and strong alkali. Conclusions The proportion of eighty percent with alcohol sinking, decorticating the outer cuticle of fresh aloe has the higher content and the better character in the polysaccharide of aloe.
