| 1 | Liver-specific gene expression in mesenchymal stem cells is induced by liver cells显示文摘AIM: The origin of putative liver cells from distinct bone marrow stem cells, e.g. hematopoietic stem cells or multipotent adult progenitor cells was found in recent in vitro studies. Cell culture experiments revealed a key role of growth factors for the induction of liver-specific genes in stem cell cultures. We investigated the potential of rat mesenchymal stem cells (MSC) from bone marrow to differentiate into hepatocytic cells in vitro. Furthermore,we assessed the influence of cocultured liver cells on induction of liver-specific gene expression.METHODS: Mesenchymal stem cells were marked with green fluorescent protein (GFP) by retroviral gene transduction. Clonal marked MSC were either cultured under liver stimulating conditions using fibronectin-coated culture dishes and medium supplemented with SCF, HGF,EGF, and FGF-4 alone, or in presence of freshly isolated rat liver cells. Cells in cocultures were harvested and GFP+ or GFP- cells were separated using fluorescence activated cell sorting. RT-PCR analysis for the stem cell marker Thy1 and the hepatocytic markers CK-18, albumin, CK-19,and AFP was performed in the different cell populations.RESULTS: Under the specified culture conditions, rat MSC cocultured with liver cells expressed albumin-, CK-18,CK-19, and AFP-RNA over 3 weeks, whereas MSC cultured alone did not show liver specific gene expression.CONCLUSION: The results indicate that (1) rat MSC from bone marrow can differentiate towards hepatocytic lineage in vitro, and (2) that the microenvironment plays a decisive role for the induction of hepatic differentiation of rMSC. | Claudia Lange Philipp Bassler Michael V.

| 3 | 大鼠肾移植1000例经验总结显示文摘目的:对大鼠肾移植进行经验总结以指导实验与临床研究。方法:作者在2004-01/2009-07海德堡大学移植中心期间,采用大鼠肾动、静脉与腹主动脉、腔静脉行端侧吻合。对于急性肾移植模型,输尿管直接植入膀胱内;对于慢性肾移植模型,输尿管采用端端吻合法。术中直接切除对侧肾脏,完成大鼠肾移植1000例,并对其进行总结。结果:只要供体肾脏冲洗良好,吻合时暖缺血时间小于30min,手术时间60min左右,吻合技术娴熟,移植成功率达98%以上。结论:该实验模型安全、方便、可行。肾移植成功的关键是手术技术。 | 李占清 关晓海 王世军 陈晶 伊雪 邬鹏宇 肖志 Nickkholgh Arash Bruns Helge Hoffmann Katrin Schemmer Peter | 2011 | 中国组织工程研究与临床康复2011，15，5： | 7 |

| 5 | Quality of life after curative liver resection: A single center analysis显示文摘AIM: To evaluate quality of life (QoL) after curative liver resection and identify variables associated with decreased QoL. METHODS: From October 2001 to July 2004, 323 patients underwent liver resection. At 3-36 mo after discharge, 188 patients were disease free. QoL was assessed using the Short Form (SF)-12 Health Survey with mental and physical component scales (SF-12 MCS and PCS), supplemented with generic questions concerning pain and liver-specific items. RESULTS: Sixty-eight percent (128/188) returned the questionnaire, which was completed in 75% (96/128) of cases. Median SF-12 PCS and MCS were 46.7 (inter- quartile range: 34.2-53.9) and 54.1 (42.8-58.2). Fifty percent were pain free with a median symptom score of 1.75 (1.38-2.13). PCS was higher after major hepatec-tomy [57% (55/96)] compared to minor resection (P = 0.0049), which represented an improved QoL. QoL was not affected by sex but by age compared to the general German population. MCS was higher after liver surgery for metastatic disease [55.9 (47.5-58.8)] compared to primary carcinoma [49.6 (36.5-55.1)] and benign disease [49.2 (37.7-56.3)] (P = 0.0317). There was no correlation between length of postoperative period and QoL. Pain, def iciencies in everyday life and a high symptom score significantly decreased MCS and PCS. CONCLUSION: Most patients were only marginally affected even after major liver resection; however, minor complications were associated with decreased SF-12 MCS and PCS and need careful attention. | Helge Bruns Kirsten Krtschmer Ulf Hinz Anette Brechtel Monika Keller Markus W Büchler Peter Schemmer | 2010 | World Journal of Gastroenterology2010，16，19： | 2 |
| 6 | Early markers of reperfusion injury after liver transplantation: association with primary dysfunction显示文摘BACKGROUND:In patients with end-stage liver disease,liver transplantation is the only available curative treatment.Although the outcome and quality of life in the patients have improved over the past decades,primary dys-or nonfunction(PDF/PNF)can occur.Early detection of PDF and PNF is crucial and could lead to individual therapies.This study was designed to identify early markers of reperfusion injury and PDF in liver biopsies taken during the first hour after reperfusion.METHODS:Biopsies from donor livers were prospectively taken as a routine during the first hour after reperfusion.Recipient data,transaminases and outcome were routinely monitored.In total,10 biopsy specimens taken from patients with 90-day mortality and PDF,and patients with long-term survival but without PDF were used for DNA microarrays.Markers that were significantly up-or down-regulated in the microarray were verified using quantitative real-time PCR.RESULTS:Age,indications and lab MELD score were similar in both groups.Peak-transaminases during the first week after transplantation were significantly different in the two groups.In total,20 differentially regulated markers that correlated to PDF were identified using microarray analysis and verified with quantitative real-time PCR.CONCLUSIONS:The markers identified in this study could predict PDF at a very early time point and might point to interventions that ameliorate reperfusion injury and thus prevent PDF.Identification of patients and organs at risk might lead to individualized therapies and could ultimately improve outcome. | Helge Bruns Jan Heil Daniel Schultze Mohammed Al Saeedi Peter Schemmer | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，3： | 1 |
