Early operation for fulminant acute pancreatitis: a possible way to decrease mortality

Background Although the indication and the timing for surgery in fulminant acute pancreatitis (FAP) are still controversial, our experience of surgical treatment for fulminant acute pancreaUtis may help improve the outcome for patients.Methods The clinical data of twenty-six patients with FAP from January 1, 2001 to October 1,2005 were analyzed. The diagnostic criteria fitted the 2007 Guidelines for the Management of Severe Acute Pancreatitis by the Chinese Medical Association.Results Twenty-six patients with FAP received surgical debridement, with a mortality rate of 42.3% (11/26). The postoperative mortalities in the ＞72 hour operation group and the <72 hour operation group were highly significantly different (7/8 vs 22.2% (4/18), respectively).Conclusions Early surgery may reduce the intraabdominal pressure and prevent the deterioration of FAP. An operation within 72 hours from the onset of symptoms might decrease the mortality of the disease.     

Pretreatment with Tongxinluo protects porcine myocardium from ischaemia/reperfusion injury through a nitric oxide related mechanism

Background The traditional Chinese medicine Tongxinluo can protect myocardium against ischaemia/reperfusion injury, but the mechanism of its action is not well documented. We examined the involvement of nitric oxide in the protective role of Tongxinluo. Methods Miniswine were randomized to four groups of seven: sham, control, Tongxinluo and Tongxinluo coadministration with a nitric oxide synthase inhibitor Nω-nitro-L-arginine (L-NNA, 10 mg/kg i.v.). Three hours after administration of Tongxinluo, the animals were anaesthetised and the left anterior descending coronary artery ligated and maintained in situ for 90 minutes followed by 3 hours of reperfusion before death. Area of no reflow and necrosis and risk region were determined pathologically by planimetry. The degree of neutrophil accumulation in myocardium was obtained by measuring myeloperoxidase activity and histological analysis. Myocardial endothelial nitric oxide synthase activity and vascular endothelial cadherin content were measured by colorimetric method and immunoblotting analysis respectively.Results Tongxinluo significantly increased the local blood flow and limited the infarct and size of no reflow. Tongxinluo also attenuated myeloperoxidase activity and neutrophil accumulation in histological sections and maintained the level of vascular endothelial cadherin and endothelial nitric oxide synthase activity in the reflow region when compared with control group. The protection of Tongxinluo was counteracted by coadministration with L-NNA. Conclusions Tongxinluo may limit myocardial ischaemia and protect the heart against reperfusion injury. Tongxinluo regulates synthesis of nitric oxide by altering activity of endothelial nitric oxide synthase.
