| 1 | A nuclear import inhibitory peptide ameliorates the severity of cholecystokinin-induced acute pancreatitis显示文摘AIM: To assess the effect of our novel cell-permeable nuclear factor-kappaB (NF-κB) inhibitor peptide PN50 in an experimental model of acute pancreatitis. PN50 was produced by conjugating the cell-penetrating penetratin peptide with the nuclear localization signal of the NF-κB p50 subunit.METHODS: Pancreatitis was induced in male Wistar rats by administering 2×100 μg/kg body weight of cholecystokininoctapeptide (CCK) intraperitoneally (IP) at an interval of 1 h. PN50-treated animals received 1 mg/kg of PN50 IP 30 min before or after the CCK injections. The animals were sacrificed 4 h after the first injection of CCK.RESULTS: All the examined laboratory (the pancreatic weight/body weight ratio, serum amylase activity,pancreatic levels of TNF-α and IL-6, degree of lipid peroxidation, reduced glutathione levels, NF-κB binding activity, pancreatic and lung myeloperoxidase activity) and morphological parameters of the disease were improved before and after treatment with the PN50 peptide.According to the histological findings, PN50 protected the animals against acute pancreatitis by favoring the induction of apoptotic, as opposed to necrotic acinar cell death associated with severe acute pancreatitis.CONCLUSION: Our study implies that reversible inhibitors of stress-responsive transcription factors like NF-κB might be clinically useful for the suppression of the severity of acute pancreatitis. | Tamás Letoha Csaba Somlai Tamáas Takács Annamária Szabolcs Katalin Jármay Zoltán Rakonczay Jr Péter Hegyi Ilona Varga József Kaszaki István Krizbai Imre Boros Ern(?)

| 2 | Outcome of 1355 consecutive transabdominal chorionic villus samplings in 1351 patients显示文摘Background The true risk of choronic villus sampling (C VS) is poorly defined. The objective of this study was to review the clinical o utcome of transabdominal CVS performed in a university teaching unit, with an em phasis on the complication rate. Methods A comprehensive audit database was maintained for 1351 pregnant women, including 17 sets of twin pregnancies, who had a CVS. Details a nd outcome of all CVSs made in the unit between May 1996 and May 2004 were revie wed. All CVSs were performed by one of 5 operators using the identical techniqu es. Results All procedures were performed transabdominally. A tota l of 1355 CVSs were performed because there were 4 dichorionic twin pregnancies which required 2 punctures. The mean gestation at CVS was (11.8±0.7) weeks, and 97.3% of the procedures were performed between 11 and 13 completed weeks. The majority (96.2%) required only 1 puncture to achieve correct needle placeme nt. The procedure failed to obtain an adequate sample in 4 subjects (0.30%). A total of 1351 chromosomal studies were requested and there was 1 case (0.07%) of culture failure. The results of chromosomal studies were available within 1 4 days in 36.7% of the cases and within 21 days in 94.0%. Overall, 77 chromos omal abnormalities (5.7%) and 5 cases of thalassemia major were detected. Preg nancy outcome was unknown in only 13 singleton subjects (0.96%). In the remain ing 1355 fetuses, there were 76 pregnancy terminations (5.56%), 10 fetal losses with obvious obstetric causes (0.73%), and 21 potentially procedure-relat ed fetal losses (1.54%). In the last group, the majority had one or more co-e xisting obstetric complications. The background fetal loss rate for pregnancies at similar gestational age in the unit was about 0.8%. Therefore, the procedu re-related fetal loss rate was estimated to be at the maximum of 0.74%. Conclusions In experienced hands, first trimester transabdomina l CVS is an accurate and safe invasive prenatal diagnostic procedure. It should be one of the treatment options available to pregnant women who require prenata l genetic diagnosis. | LAU Tze Kin LEUNG Tak Yeung FUNG Tak Yuen Daljit S SAHOTA LEUNG Tse Ngong | 2005 | Chinese Medical Journal2005，，20： | 8 |
| 3 | Therapeutic proteasome inhibition in experimental acute pancreatitis显示文摘AIM: To establish the therapeutic potential of proteasome inhibition, we examined the therapeutic effects of MG132 (Z-Leu-Leu-Leu-aldehyde) in an experimental model of acute pancreatitis.METHODS: Pancreatitis was induced in rats by two hourly intraperitoneal (ip) injections of cholecystokinin octapeptide (CCK; 2 x 100 μg/kg) and the proteasome inhibitor MG132 (10 mg/kg ip) was administered 30 min after the second CCK injection. Animals were sacrificed 4 h after the first injection of CCK.RESULTS: Administering the proteasome inhibitor MG132 (at a dose of 10 mg/kg, ip) 90 min after the onset of pancreatic inflammation induced the expression of cell-protective 72 kDa heat shock protein (HSP72) and decreased DNA-binding of nuclear factor-kB (NF-kB). Furthermore MG132 treatment resulted in milder inflammatory response and cellular damage, as revealed by improved laboratory and histological parameters of pancreatitis and associated oxidative stress.CONCLUSION: Our findings suggest that proteasome inhibition might be beneficial not only for the prevention, but also for the therapy of acute pancreatitis. | Tamás Letoha Liliána Z Fehér László Pecze Csaba Somlai Ilona Varga József Kaszaki Gábor Tóth Csaba Vizler László Tiszlavicz Tamás Takács | 2007 | World Journal of Gastroenterology2007，13，33： | 5 |
| 4 | Diagnostic role of secretin-enhanced MRCP in patients with unsuccessful ERCP显示文摘AIM: To evaluate the value of MR cholangiopancreatography (MRCP) in patients in whom endoscopic retrograde cholangiopancreatography (ERCP) was unsuccessfully performed by experts in a tertiary center. METHODS: From January 2000 to June 2003, 22 patients fulfilled the inclusion criteria. The indications for ERCP were obstructive jaundice (n = 9), abnormal liver enzymes (n=8),suspected chronic pancreatitis (n = 2), recurrent acute pancreatitis (n = 2), or suspected pancreatic cancer (n=1). The reasons for the ERCP failure were the postsurgical anatomy (n = 7), duodenal stenosis (n = 3), duodenal diverticulum (n = 2), and technical failure (n = 10). MRCP images were evaluated before and 5 and 10 min after i.v. administration of 0.5 IU/kg secretin.RESULTS: The MRCP images were diagnosed in all 21patients. Five patients gave normal MR findings and required no further intervention. MRCP revealed abnormalities (primary sclerosing cholangitis, chronic pancreatitis, cholangitis, cholecystolithiasis or common bile duct dilation) in 10 patients, who were followed up clinically. Four patients subsequently underwent laparotomy (hepaticojejunostomy in consequence of common bile duct stenosis caused by unresectable pancreatic cancer; hepaticotomy+Kehr drainage because of insufficient biliary-enteric anastomosis; choledochojejunostomy, gastrojejunostomy and cysto-Wirsungo gastrostomy because of chronic pancreatitis, orcholedo chojejunostomy because of common bile duct stenosis caused by chronic pancreatitis). Three patients participated in therapeutic percutaneous transhepatic drainage. The indications were choledocholithiasis with choledochojejunostomy, insufficient biliary-enteric anastomosis, or cholangiocarcinoma. CONCLUSION: MRCP can assist the diagnosis and management of patients in whom ERCP is not possible. | László Czakó Tamás Takács Zita Morvay László Csernay János Lonovics | 2004 | World Journal of Gastroenterology2004，10，20： | 3 |
