| 1 | Comprehensive and innovative techniques for livertransplantation in rats: A surgical guide显示文摘AIM: To investigate our learning curves of orthotopic liver transplantation (OLT) in rats and the most important factor for successful surgery. METHODS: We describe the surgical procedures for our rat OLT model, and determined the operator learning curves. The various factors that contributed to successful surgery were determined. The most important surgical factors were evaluated between successful and unsuccessful surgeries.RESULTS: Learning curve data indicated that 50 cases were required for operator training to start a study. Operative time, blood loss, warm ischemic time, anhepatic phase, unstable systemic hemodynamic state, and body temperature after surgery significantly affected surgery success by univariate analysis, while the anhepatic phase was the most critical factor for success by multivariate analysis. CONCLUSION: OLT in rats is the only liver transplantation model that provides clinically relevant and reliable results. Shortened anhepatic phase is key to success in this model. | Tomohide Hori Justin H Nguyen Yasuhiro Ogura Toshiyuki Hata Shintaro Yagi Ann-Marie T Baine Norifumi Ohashi Christopher B Eckman Aimee R Herdt Hiroto Egawa Yasutsugu Takada Fumitaka Oike Seisuke Saka-moto Mureo Kasahara Kohei Ogawa Koichiro Hata Taku Iida Yukihide Yonekawa Lena Sibulesky Kagemasa Kuribayashi Takuma Kato Kanako Saito Mie Torii Naruhiko Sahara Naoko Kamo Tomoko Sahara Motohiko Yasutomi Shinji Uemoto | 2010 | World Journal of Gastroenterology2010，16，25： | 14 |
| 2 | Oxidative stress and extracellular matrices after hepatectomy and liver transplantation in rats显示文摘AIM:To investigate oxidative stress(OS)-mediated damage and the behavior of extracellular matrices in various rat models because shear stress with portal hypertension and cold ischemia/warm reperfusion injury trigger the liver regeneration cascade after surgery. These injuries also cause fatal liver damage.METHODS: Rats were divided into four groups according to the surgery performed: control; hepatectomy with 40% liver remnant(60% hepatectomy); orthotopic liver transplantation(OLT) with whole liver graft(100% OLT); and split OLT(SOLT) with 40% graft(40% SOLT). Survival was evaluated. Blood and liver samples were collected at 6 h after surgery. Biochemical and histopathological examinations were performed. OSinduced damage, 4-hydroxynonenal, ataxia-telangiectasia mutated kinase, histone H2AX, phosphatidylinositol 3-kinase(PI3K) and Akt were evaluated by western blotting. Behavior of extracellular matrices, matrix metalloproteinase(MMP)-9, MMP-2, tissue inhibitor of metalloproteinase(TIMP)-1 and TIMP-2 were also evaluated by western blotting and zymography. RESULTS: Although 100% OLT survived, 60% hepatectomy and 40% SOLT showed poor survival. Histopathological, immunohistological, biochemical and protein assays revealed that 60% hepatectomy, 100% OLT and 40% SOLT showed liver damage. PI3K and Akt were decreased in 60% hepatectomy and 40% SOLT. For protein expression, 40% SOLT showed differences in MMP-9, MMP-2 and TIMP-2. TIMP-1 showed differences in 60% hepatectomy and 40% SOLT. For protein activity, MMP-9 demonstrated significant differences in 60% hepatectomy, 100% OLT and 40% SOLT. CONCLUSION: Under conditions with an insufficient liver remnant, prevention of OS-induced damage via the Akt/PI3K pathway may be key to improve the postoperative course. MMP-9 may be also a therapeutic target after surgery. | Tomohide Hori Shinji Uemoto Feng Chen Lindsay B Gardner Ann-Marie T Baine Toshiyuki Hata Takayuki Kogure Justin H Nguyen | 2014 | World Journal of Hepatology2014，6，2： | 7 |
| 3 | Simple and reproducible hepatectomy in the mouse using the clip technique显示文摘AIM: To investigate the reliability of massive hepatectomy models by using clip techniques. METHODS: We analyzed anatomical findings in 100 mice following massive hepatectomy induced by liver reduction > 70%. The impact of various factors in the different models was also analyzed, including learning curves, operative time, survival curves, and histopathological findings.RESULTS: According to anatomical results, models with 75%, 80%, and 90% hepatectomy produced massive hepatectomy. Learning curves and operative times were most optimal with the clip technique. Each hepatectomy performed using the clip technique produced a reasonable survival curve, and there were no differences in histopathological findings between the suture and clip techniques. CONCLUSION: Massive hepatectomy by the clip technique is simple and can provide reliable and relevant data. | Tomohide Hori Norifumi Ohashi Feng Chen Ann-Marie T Baine Lindsay B Gardner Toshiyuki Hata Shinji Uemoto Justin H Nguyen | 2012 | World Journal of Gastroenterology2012，18，22： | 4 |

| 11 | Fulminant liver failure models with subsequent encephalopathy in the mouse显示文摘BACKGROUND:A reliable model of fulminant liver failure (FLF) is urgently required in this research field.This study aimed to develop a murine FLF model.METHODS:We used three groups of male C57BL/6 mice:control,with azoxymethane treatment (AOM group),and with galactosamine and tumor necrosis factor-alpha treatment (Gal+TNF-α group).The effects of body temperature (BT) control on survival in all three groups were investigated Using BT control,we compared the survival,histopathological findings and biochemical/coagulation profiles between the two experimental groups.The effects of hydration on international normalized ratios of prothrombin time (PT INRs) were also checked.Dose-dependent survival curves were constructed for both experimental groups.Neurological behavior was assessed using a coma scale.RESULTS:No unexpected BT effects were seen in the control group.The AOM group,but not the Gal+TNF-α group showed a significant difference in survival curves between those with and without BT care.Histopathological assessment showed consistent FLF findings in both experimental groups with BT care.There were significant differences between the experimental groups in aspartate aminotransferase levels and PTINRs,and significant differences in PT-INRs between the sufficiently and insufficiently hydrated groups.There were significant differences between FLF models in the duration of each coma stage,with significant differences in stages 1 and 3 as percentages of the disease state (stages 1-4).The two FLF models with BT care showed different survival curves in the dose-dependent survival study.CONCLUSIONS:AOM provides a good FLF model,but requires a specialized environment and careful BT control.Other FLF models may also be useful,depending on the research purpose.Thoughtful attention to caregiving and close observation are indispensable for successful FLF models. | Ann-Marie T Baine Tomohide Hori Lindsay B Gardner Shinji Uemoto Justin H Nguyen | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，6： | 1 |

| 17 | Thrombotic microangiopathy-like disorder after living-donor liver transplantation:A single-center experience in Japan显示文摘AIM:To investigate thrombotic microangiopathy (TMA)in liver transplantion,because TMA is an infrequent but life-threatening complication in the transplantation field. METHODS:A total of 206 patients who underwent living-donor liver transplantation (LDLT) were evaluated,and the TMA-like disorder (TMALD) occurred in seven recipients. RESULTS:These TMALD recipients showed poor outcomes in comparison with other 199 recipients. Although two TMALD recipients successfully recovered,the other five recipients finally died despite intensive treatments including repeated plasma exchange (PE) and re-transplantation. Histopathological analysis of liver biopsies after LDLT revealed obvious differences according to the outcomes. Qualitative analysis of antibodies against a disintegrin-like domain and metalloproteinase with thrombospondin type 1 motifs (ADAMTS-13) were negative in all patients. The fragmentation of red cells,the microhemorrhagic macules and the platelet counts were early markers for the suspicion of TMALD after LDLT. Although the absolute values of von Willebrand factor (vWF) and ADAMTS-13 did not necessarily reflect TMALD,the vWF/ADAMTS-13 ratio had a clear diagnostic value in all cases. The establishment of adequate treatments for TMALD,such as PE for ADAMTS-13 replenishment or treatments against inhibitory antibodies,must be decided according to each case. CONCLUSION:The optimal induction of adequate therapies based on early recognition of TMALD by the reliable markers may confer a large advantage for TMALD after LDLT. | Tomohide Hori Toshimi Kaido Fumitaka Oike Yasuhiro Ogura Kohei Ogawa Yukihide Yonekawa Koichiro Hata Yoshiya Kawaguchi Mikiko Ueda Akira Mori Yasutsugu Takada Hiroto Egawa Atsushi Yoshizawa Shinji Uemoto Hajime Segawa Kimiko Yurugi Takuma Kato Kanako Saito Linan Wan Mie Torii Feng Chen Ann-Marie T Baine Lindsay B Gardner | 2011 | World Journal of Gastroenterology2011，17，14： | 1 |
