胰腺炎大鼠血清酶学变化及胸腺肽α_1对其的调节作用

重症胰腺炎(severe acute pancreatitis，SAP)是临床上一种常见的急症，在其发生、发展过程中，血清酶学的变化是临床上观察病情演变的主要指标。胸腺肽α1(thymic peptide α1)作为一种免疫调节剂，在阻抑重症炎症反应，抑制炎性介质释放等方面有良好的作用。我们拟进一步探讨SAP大鼠血清酶学改变及胸腺肽α1对其的调节作用。     

The study of correlative factors to resistin and its regression equation in type 2 diabetes

Objective To study the changes of resistin and the relationship between resistin and other indexes in patients with type 2 diabetes mellitus. Methods Seventy patients with type 2 diabetics were chosen and divided into three groups according to weight index and 15 healthy persons were chosen as controls. ELISA was adopted to determine resistin concentration. Oxydase method was adopted to measure blood sugar. Radio immunoassay was used to measure insulin level. Results Resistin concentration of patient groups r(23.06±9.34)μg/L ] was significantly higher than that of control group [( 9. 89±4. 47) μg/L, P<0. 01 ]. Resistin was positively related to body mass index (r = 0.4 467) and fat distribution (r= 0. 3 314, P<0.01). Resistin was also positively correlated to the area under the curve of sugar tolerance (r=0. 7 063, P<0. 01), negatively related to the insulin resistance index (r=-0. 4 154, P<0.01), but not related to area under the curve of synchronous insulin release (P>0. 05). And a formula was obtainted : Resistin=- 15. 869 0. 339×GAUC 0.790×BMI. Conclusion The level of reslstin in type 2 diabetics is higher. And reslstin is related to other factors. This formula is of great significance for clinical study of diabetic's disor- ders.     

抵抗素、血脂及有关生化指标在2型糖尿病患者中的变化

目的探讨抵抗素、血脂及肝功能指标在2型糖尿病患者内环境紊乱中的变化情况。方法70例2型糖尿病患者(2DM组)和15例正常人(对照组)分别采取清晨空腹静脉血,应用酶联免疫吸附试验测定抵抗素,放射免疫分析法测定胰岛素,全自动生化分析仪检测血糖、血脂及肝功能指标。结果①2DM组的空腹血糖平均为(8.85±3.21)mmol/L,空腹胰岛素平均为(11.12±4.54)mU/L,抵抗素平均含量为(23.06±9.34)μg/L,均显著高于对照组(P<0.01)。②2DM组的胆固醇、三酰甘油及尿微量白蛋白分别为(5.51±1.37)mmol/L、(2.48±1.60)mmol/L和(28.49±41.18)mg/24h,均显著高于对照组(P<0.05)。而谷丙转氨酶、谷草转氨酶、高密度脂蛋白胆固醇和脂蛋白a在两组之间无明显差异(P>0.05)。结论糖尿病患者存在内环境的紊乱,其体内含有较高浓度的抵抗素,并存在血脂代谢异常和尿微量白蛋白的增高。
