作者： Liangcai peng neal Gutterson National Key Laboratory of Crop Genetic Improvement Biomass and Bioenergy Research Center Huazhong Agricultural University Wuhan 430070 China Mendel Biotechnology Inc. Hayward CA 94720 USA

Selection of energy crops is the first priority for large-scale biofuel production in China. As a major topic, it was extensively discussed in the Second International Symposium on Bioenergy and Biotechnology, held from October 16-19th, 2010 in Huazhong Agricultural University （HZAU）, Wuhan, Cllina, with more than one hundred registered participants （Figure, 1）. In the opening ceremony, Liangcai peng, Chair of the organization committee, briefly described bioenergy research progress in HZAU over the past two and a half years since the first symposium was held there in March 16-18th, 2008.

Failure of p-selectin blockade alone to protect the liver from ischemia-reperfusion injury in the isolated blood-perfused rat liver

引用

World Journal of Gastroenterology 2008年第44期14卷 6808-6816页

作者： Samuel Wyllie neal R Barshes Saul J Karpen John A Goss Michael E. DeBakey Department of Surgery Liver Transplant Center LaboratoryBaylor College of MedicineHoustonTX 77030United States

AIM： To determine if blockade of p-selectin in the isolated blood-perfused cold ex vivo rat liver model protects the liver from ischemia-reperfusion injury. METHODS： The effect of p-selectin blockade was assessed by employing an isolated blood-perfused cold ex vivo rat liver with or without p-selectin antibody treatment before and after 6 h of cold storage in University of Wisconsin solution. RESULTS： In our isolated blood-perfused rat liver model, pre-treatment with p-selectin antibody failed to protect the liver from ischemia-reperfusion injury, as judged by the elevated aspartate aminotransferase activity. In addition, p-selectin antibody treatment did not significantly reduced hepatic polymorphonuclear leukocyte accumulation after 120 min of perfusion. Histological evaluation of liver sections obtained at 120 min of perfusion showed significant oncotic necrosis in liver sections of both ischemic control and p-selectin antibody-treated groups. However, total bile production after 120 rain of perfusion was significantly greater in p-selectin antibody-treated livers, compared to control livers. No significant difference in p-selectin and ICAM-1 mRNAs and proteins, GSH, GSSG, and nuclear NF-kB was found between control and p-selectin antibody-treated livers. CONCLUSION： In conclusion, we have shown that blockade of p-selectin alone failed to reduced polymorphonuclear leukocyte accumulation in the liver and protect hepatocytes from ischemia-reperfusion injury in the isolated blood-perfused cold-ex vivo rat liver model.
