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.

The mutation of insulin receptor substrate-1 gene in Chines e patients with non-insulin-dependent diabetes mellitus

Objective To identify the relationship between mutation in the insulin receptor substrate-1 (IRS-1) gene and the incidence of non-insulin-dependent diabetes mellitus (NIDDM) in the Chinese population. Methods Samples were obtained from 68 Chinese patients with NIDDM and 68 control subjects. The +1700～+4437 bp fragment of the IRS-1 gene was screened by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) analysis. All SSCP variations were submitted to DNA sequence analysis. Results Two amino acid variations ［GGG →AGG(G(971) R) and CCT→TCT(P(1079) S)］ and 3 silent mutations ［GAT→GAC(D(422) D), CCA→CCC(P(737) P) and GCA→GCG(A(804) A)］ were identified, among which the CCA→CCC(P(737) P) and CCT→TCT(P(1079) S) have not been previously reported. All five variations were found in Chinese patients with NIDDM, while GCA→GCG(A(804) A) was the only one found in control subjects. The overall incidence of the five variations in Chinese patients with NIDDM were much higher than that in control subjects (38.2% vs 7.4%, χ(2)=18.42,P&lt;0.01). The most common polymorphism in the Chinese population was GCA→GCG(A(804) A), and its frequency was significantly higher in Chinese patients with NIDDM than in controls (26.5% vs 7.4%, χ(2)=8.84,P&lt;0.01). The homozygotes of the variation in patients with NIDDM and control subjects were 8.8% and 1.5%, respectively (χ(2)=2.41,P&gt;0.05). Conclusion These results indicate that there may be a relation between these nucleotide variations of IRS-1 gene and Chinese patients with NIDDM
