  • Influence of Hepatectomy Combined with Internal Biliary Drainage in Obstructive Jaundice Rats

    ObjectiveTo study the effectiveness of liver function, hepatic energy metabolism, regeneration, and apoptosis on the obstructive jaundice rat after partial hepatectomy (PH) combined with internal biliary drainage under the condition of conspicuous bilirubinemia. MethodsOne hundred and twenty male SD rats were used in research, six of whom were divided into sham operation (SO) group. Twenty rats underwent bridge operation between common bile duct and duodenum after 70% PH (70%PH group), and 6 rats out of the 94 rats who underwent common bile duct ligation (CBDL) for 5 d were randomly selected as CBDL group, and the residual rats were done the second operations after 5 d and were divided into three groups: bile duct obstruction combined with reperfusion of bile flow group (BDO-RBF group, n=20), 42% PH with BDO-RBF group (n=20), and 70%PH with BDO-RBF group (n=25). Levels of TB, ALT, ALB, and ALP in serum; HGF, bcl-2 mRNA and protein; ATP, ADP, and AMP; hepatocyte proliferation/apoptosis index in hepatic tissues were dynamically observed after operation (24 h, 72 h, and 7 d), respectively. The liver function and hepatocyte energy metabolism were only detected in the SO group. ResultsRats without obstructive jaundice would have an excellent liver regeneration after 70% PH, while the liver function and hepatocyte energy metabolism could recover rapidly. The liver function, hepatocyte energy metabolism, HGF and bcl-2 mRNA and protein of liver tissue and the hepatocyte proliferation/apoptosis index in partial (42% or 70%) hepatectomy combined with internal biliary drainage in obstructive jaundice group were significantly influenced while recovered rapidly (Plt;0.05). ConclusionsUnder the condition of conspicuous bilirubinemia, the influences of hepatectomy combined with internal biliary drainage on hepatocyte energy metabolism, liver function, hepatocyte regeneration and apoptosis are severer than that of normal rats who underwent 70% hepatectomy, while also make the rats recover rapidly in hyperbilirubinemia groups. The database suggest that it is not necessary to do preoperative external biliary drainage before performing liver resection.

  • Role of NMDA Receptor in Central Nervous System Injury of Obstructive Jaundice

    ObjectiveTo evaluate the role of N-methyl-D-aspartate (NMDA) receptor in central nervous system (CNS) injury of obstructive jaundice. MethodThe related literatures about NMDA receptor and the CNS injury caused by hyperbilirubinemia were retrieved and reviewed. ResultsThe CNS injury of obstructive jaundice was related to overactivation of NMDA receptor, which finally resulted in degeneration and necrosis of nerve cells. The NMDA receptor antagonist MK-801 could relieve the CNS injury of obstructive jaundice. ConclusionsNMDA receptor plays an important role in the CNS injury caused by hyperbilirubinemia, and the blocker of NMDA receptor has protective effects in this process. However, there is no report of MK-801 in clinical application when hyperbilirubinemia happened.
