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     

肾功能分级在成人心脏术后肾功能衰竭的应用

Objective To evaluate the ability of the RIFLE classification to predict hospital mortality in adult patients who underwent cardiac surgery. Methods From October Ist 2006 to December 31st 2006, five hundred and nine adult patients who underwent coronary artery bypass grafting and/or valve operation were enrolled in this study. Renal function was assessed daily according to the RIFLE classification, meanwhile, APACHE Ⅱ score and SOFA score were also evaluated, as well as the maximum scores were recorded. Results Mean duration of ventilation support was 18(14 - 19) hours, the time of ICU stay was 1.4 ± 1.0 days, and the time of postoperative hospital stay was 12. 0(10.0- 15.0) days. 167 patients (32. 8%) incurred postoperative ARF according to the RIFLE classification. The overall mortality was 4. 3% (22/502). A significant increase (P < 0. 01) was observed for mortality based on RIFLE classification. By applying the area under the receiver operating characteristic curve, the RIFLE classification had more powerful discrimination power [0. 933, (95% CI 0. 872 -0. 995) ,P <0. 001]. Conclusions ARF is one of the major complications in postcardiotomy patients. Analytical data suggested the good discriminative power of the RIFLE classification for predicting inpatient mortality of adult postoperative patient with ARF, and the RIFLE classification is simple and practically performed. According to the RIFLE classification, patients with RIFLE class I or class F incur a significantly increased risk of in-hospital mortality compared with those who never develop ARF.
