2Protective effects of ischemic preconditioning and application of lipoic acid prior to 90 min of hepatic ischemia in a rat model显示文摘AIM: To compare different preconditioning strategies to protect the liver from ischemia/reperfusion injury focusing on the expression of pro- and anti-apoptotic proteins. Interventions comprised different modes of ischemic preconditioning (IP) as well as pharmacologic pretreatment by α-lipoic acid (LA). METHODS: Several groups of rats were compared: sham operated animals, non-pretreated animals (nt), animals receiving IP (10 min of ischemia by clamping of the portal triad and 10 min of reperfusion) prior to sustained ischemia, animals receiving selective ischemic preconditioning (IPsel, 10 min of ischemia by selective clamping of the ischemic lobe and 10 min of reperfusion) prior to sustained ichemia, and animals receiving 500 μmol α-LA injected i.v. 15 min prior to the induction of 90 min of selective ischemia. RESULTS: Cellular damage was decreased only in the LA group. TUNEL-positive hepatocytes as well as necrotic hepatocyte injury were also decreased only by LA (19 ± 2 vs 10 ± 1, P < 0.05 and 29 ± 5 vs 12 ± 1, P < 0.05). Whereas caspase 3- activities in liver tissue were unchanged, caspase 9- activity in liver tissue was decreased only by LA pretreatment (3.1 ± 0.3 vs 1.8 ± 0.2, P < 0.05). Survival rate as the endpoint of liver function was increased after IP and LA pretreatment but not after IPsel. Levels of lipid peroxidation (LPO) in liver tissue were decreased in the IP as well as in the LA group compared to the nt group. Determination of pro- and anti-apoptotic proteins showed a shift towardsanti-apoptotic proteins by LA. In contrast, both our IP strategies failed to influence apototic cell death. CONCLUSION: IP, consisting of 10 min of ischemia and 10 min of reperfusion, protects only partly against ischemia/reperfusion injury of the liver prior to 90 min of selective ischemia. IPsel did not influence ischemic tolerance of the liver. LA improved tolerance to ischemia, possibly by downregulation of pro-apoptotic Bax.Friedrich Duenschede Kirsten Erbes Nina Riegler Patrick Ewald Achim Kircher Stefanie Westermann Arno Schad Imke Miesmer Simon Albrecht-Schck Ines Gockel Alexandra K Kiemer Theodor Junginger 2007World Journal of Gastroenterology2007,13,27:8

4Reduction of ischemia reperfusion injury after liver resection and hepatic inflow occlusion by α-lipoic acid in humans显示文摘AIM: To evaluate the protective effects of precondition- ing by α-lipoic acid (LA) in patients undergoing hepatic resection under inflow occlusion of the liver. METHODS: Twenty-four patients undergoing liver re- section for various reasons either received 600 mg LA or NaCl 15 min before transection performed under inflow occlusion of the liver. Blood samples and liver wedge bi- opsy samples were obtained after opening of the abdo- men immediately after inflow occlusion of the liver, and 30 min after the end of inflow occlusion of the liver. RESULTS: Serum levels of aspartate transferase and alanine transferase were reduced at all time points in patients who received LA in comparison to those who received NaCL. This was accompanied by reduced histo- morphological features of oncosis. We observed TUNEL- positive hepatocytes in the livers of the untreated patients, especially after 30 min of ischemia. LA attenu- ated this increase of TUNEL-positive hepatocytes. Under preconditioning with LA, ATP content was significantly enhanced after 30 min of ischemia and after 30 min of reperfusion. CONCLUSION: This is the first report on the poten- tial for LA reducing ischemia/reperfusion injury (IRI) of the liver in humans who were undergoing liver surgery. Beside its simple and rapid application, side effects did not occur. LA might therefore represent a new strategy against hepatic IRI in humans.Fritz Dünschede Kirsten Erbes Achim Kircher Stefanie Westermann Joachim Seifert Arno Schad Kempski Oliver Alexandra K Kiemer Junginger Theodor 2006World Journal of Gastroenterology2006,12,42:6

7Diagnosis and endoscopic treatment of esophago-bronchial fistula due to gastric heterotopy显示文摘Heterotopic gastric mucosa patches are congenital gastrointestinal abnormalities and have been reported to occur anywhere along the gastrointestinal tract from mouth to anus.Complications of heterotopic gastric mucosa include dysphagia,upper gastrointestinal bleeding,upper esophageal ring stricture,adenocarcinoma and fistula formation.In this case report we describe the diagnosis and treatment of the first case of esophago-bronchial fistula due to heterotopic gastric mucosa in mid esophagus.A 40-year old former professional soccer player was referred to our department for treatment of an esophago-bronchial fistula.Microscopic examination of the biopsies taken from the esophageal fistula revealed the presence of gastric heterotopic mucosa.We decided to do a non-surgical therapeutic endoscopic procedure.A sclerotherapy catheter was inserted through which 1 mL of ready to use synthetic surgical glue was applied in the fistula and it closed the fistula opening with excellent results.Konstantinos H Katsanos Dimitrios K Christodoulou Sevasti Kamina Kosmidou Maria Evangelia Lambri Stavroula Theodorou Konstantinos Tsampoulas Mitsi Vasiliki Epameinondas V Tsianos 2010World Journal of Gastrointestinal Endoscopy2010,2,4:2
