| 1 | Different profiles of cytokine expression during mild and severe acute pancreatitis显示文摘AIM:To study secretion patterns of proand anti-in-flammatory cytokines, and activation of various cellular subsets of leukocytes in peripheral blood.METHODS: We have conducted a prospective obser-vational study. One hundred and eight patients with a diagnosis of acute pancreatitis and onset of the disease within last 72 h were included in this study. The mRNA expression of 25 different types of cytokines in white blood cells was determined by quantitative real time polymerase chain reaction. Levels of 8 different cytokines in blood serum were measured by enzymelinked immunosorbent assay. Clinical data and cytokine expression results were subjected to statistical analysis.RESULTS: Severe and necrotizing acute pancreatitis (AP) is characterized by the significant depletion of circulating lymphocytes. Severe acute pancreatitis is as-sociated with a typical systemic inflammatory response syndrome and over-expression of pro-inflammatory cy-tokines [interleukin (IL)-6, IL-8, macrophage migration inhibitory factor (MIF)]. Serum IL-6 and MIF concentra-tions are the best discriminators of severe and necrotiz-ing AP as well as possible fatal outcome during the early course of the disease. CONCLUSION: Deregulation of cellular immune sys-tem is a key event leading to severe and necrotizing AP. IL-6 and MIF could be used as early predictors of complications. | Zilvinas Dambrauskas Nathalia Giese Antanas Gulbinas Thomas Giese Pascal O Berberat Juozas Pundzius Giedrius Barauskas Helmut Friess | 2010 | World Journal of Gastroenterology2010，16，15： | 49 |
| 2 | 预防性回肠造口在直肠癌超低位前切除术中的应用价值显示文摘目的探讨预防性回肠造口降低直肠癌超低位前切除术后吻合口瘘发生率的临床价值。方法回顾性分析8年间行直肠癌超低位前切除术98例患者的临床资料。比较实施预防性回肠造口组(A)45例和未实施组(B)53例两组间吻合口瘘发生率的差异。结果A组仅1例发生吻合口瘘(2.2%);B组11例发生吻合口瘘(20.8%)(P(0.05)。结论有选择的预防性回肠造口,可有效降低直肠癌超低位前切除术后吻合口瘘的发生率。 | 阎玉矿 Helmut Friess Jrg Kleeff | 2007 | 中国普通外科杂志2007，16，4： | 20 |
| 3 | KAI1 gene is differently expressed in papillary and pancreatic cancer:influence on metastasis显示文摘AIM To compare KAI1 in cancer of papilla ofVater and pancreas to evaluate whether there aredifferences in biologic behavior which mightaccount for prognosis.METHODS We compared the expression in 24papillay and 29 pancreatic cancers usingNorthern blot analysis,immunochemical assayand in situ hybridization,and investigatedwhether early diagnosis or molecular differencespredict the outcome in these tumor entities.RESULTS By Northern blot analysis there is nostatistical difference of KAI1 levels in normaland cancerous papilla.No association betweenKAI1 mRNA expression and tumor stage or tumordifferentiation was found in the tumors.Byimmunohistochemical assay,KAI1 staining incytoplasm of papillary cancer cells was similarto that of normal papillary cells.By in situhybridization,the results of KAI1 mRNAexpression in normal and cancerous papilla weresimilar to those with immunohistochemicalassay.The normal and cancerous pancreastissues were also analyzed by the methods usedin papillary samples.CONCLUSION Although the biologic roles of KAI1 have not been clarified, our results suggest that KAI1 may restrict the progression of malignant papillary cancer, but its expression might not have any effect on the characteristics of papillary tumor, whereas by the analysis of KAl1 gene, its reduced expression is closely related to the progression and metastases of pancreatic cancer. | Helmut Friess Markus W.Buchler | 2000 | World Journal of Gastroenterology2000，6，6： | 20 |
| 4 | 胰腺癌细胞起源和演进的新实验证据显示文摘目的大量研究证实导管样复合体就是胰腺癌的前体病变,因此,本研究旨在探索植入致癌剂后胰腺癌前体病变的产生和发展。方法采用手术方法将致癌剂DMBA植入SD大鼠胰腺,从第1天开始,在不同的时间点获取胰腺进行组织学研究,同时,分别以糜蛋白酶和细胞角蛋白作为胰腺腺泡细胞和导管细胞的标记物,通过免疫组化方法进行定位。结果在包埋致癌剂第2天就可以观察到正常胰腺小叶向导管复合体移型的现象,第4天出现典型的导管复合体,同时,胰岛也参与了这一过程。小叶中的非导管细胞迅速转分化为导管细胞的特征。在1个月时观察到导管腺癌的形成。与对照组相比,腺泡-导管转分化过程在DMBA包埋组持续存在。结论胰腺癌前体病变(导管复合体)除了由已经存在于小叶内的导管细胞组成外,主要通过腺泡细胞转分化形成,同时,胰岛细胞在某种程度上也参与了导管复合体的形成。因此,胰腺腺泡细胞、胰岛细胞和导管细胞共同参与了胰腺导管腺癌前体细胞的起源,转分化可以不需要细胞分裂迅速发生,而恶性转化需要较长的时间。 | 郭俊超 赵玉沛 Dale E.Bockman 廖泉 Michael W.Muller Helmut Friess | 2005 | 中华肝胆外科杂志2005，11，5： | 12 |

| 6 | Pain sensation in pancreatic diseases is not uniform: The different facets of pancreatic pain显示文摘AIM: To systematically characterize specific pain patterns in the most frequent pancreatic diseases.METHODS: Pain in patients with chronic pancreatitis(n = 314), pancreatic cancer(n = 469), and other pancreatic tumors(n = 249) including mucinous(n = 20) and serous cystadenoma(n = 31), invasive(n = 37) and non-invasive intraductal papillary mucinous neoplasia(IPMN; n = 48), low stage(n = 18) and high stage neuroendocrine neoplasia(n = 44), and ampullary cancer(n = 51) was registered and correlated with clinicopathological data. Survival times were estimated by the Kaplan-Meier method. Patients alive at the follow-up time were censored. Survival curves were compared statistically using the log-rank test.RESULTS: Forty-nine point one percent of pancreatic cancer patients revealed no pain, whereas in chronic pancreatitis only 18.3% were pain free. In contrary, moderate/severe pain was registered in 15.1% in pancreatic cancer patients that was increased in chronic pancreatitis with up to 34.2%. Serous cystadenoma was asymptomatic in most cases(58.1%), whereas 78.9% of all mucinous cystadenoma patients suffered pain. In neuroendocrine neoplasia pain was not a key clinical symptom since 64% of low stage neuroendocrine neoplasia and 59% of high stage neuroendocrine neoplasia patients were pain free. Cancer localization in the pancreatic body and patients with malignant pancreatic neoplasms were associated with more severe pain. Tumor grading and stage did not show any impact on pain. Only in pancreatic cancer, pain was directly associated with impaired survival.CONCLUSION: Pancreatic pain depicts different patterns of abdominal pain sensation according to the respective pancreatic disorder and does not allow a unification of the term pancreatic pain. | Jan G D'Haese Mark Hartel Ihsan Ekin Demir Ulf Hinz Frank Bergmann Markus W Büchler Helmut Friess Güralp O Ceyhan | 2014 | World Journal of Gastroenterology2014，20，27： | 8 |

| 13 | Is laparoscopic colorectal cancer surgery equal to open surgery? An evidence based perspective显示文摘Laparoscopic colorectal surgery(LCS) is an evolving subject.Recent studies show that LCS can not only offer safe surgery but evidence is growing that this new technique can be superior to classical open procedures.Fewer perioperative complications and faster postoperative recovery are regularly mentioned when studies of LCS are presented.Even though the learning curve of LCS is frequently debated when limitations of laparoscopic surgeries are reviewed,studies show that in experienced hands LCS can be a safe procedure for colorectal cancer treatment.The learning curve however,is associated with high conversion rates and economical aspects such as higher costs and prolonged hospital stay.Nevertheless,laparoscopic colorectal cancer surgery(LCCR) offers several advantages such as less co-morbidity and less postoperative pain in comparison with open procedures.Furthermore,the good exposure of the pelvic cavity by laparoscopy and the magnification of anatomical structures seem to facilitate pelvic dissection laparoscopically.Moreover,recent studies describe no difference in safety and oncological radicalness in LCCR compared to the open total mesorectal excision(TME).The oncological adequacy of LCCR still remains unproven today,because long-term results do not yet exist.To date,only a few studies have described the results of laparoscopic TME combined with preoperative adjuvant treatment for colorectal cancer.The aim of this review is to examine the various areas of development and controversy of LCCR in comparison to the conventional open approach. | Beat M Künzli Helmut Friess Shailesh V Shrikhande | 2010 | World Journal of Gastrointestinal Surgery2010，2，4： | 3 |
