内源分泌型晚期糖化终末产物受体与2型糖尿病颈动脉内膜中层厚度相关

The carotid initima-media thickness(CIMT)in 78 cases of type 2 diabetic patients was measured.The level of plasma endogenous secretion receptor for advanced glycation end-products(esRAGE)in patients with normal CIMT was higher than those with chickened CIMT[(0.257 3±0.165 6 vs 0.155 4±0.0701)μg/L,P<0.01].esRAGE was negatively associated with CIMT(r=-0.247,P<0.05).Logistic regression analysis showed that CIMT was negatively associated with esRAGE and hish density lipoprotein cholesterol,but was positively associated with age.

测定78例2型糖尿病患者颈动脉内膜中层厚度(CIMT).CIMT正常组血浆内源分泌型晚期糖化终末产物受体(esRAGE)高于CIMT增厚组[(0.257 3±0.1656对0.155 4±0.0701)峭/L,P<0.01].esRAGE与CIMT负相关r=-0.247,P<0.05).Logistic回归分析显示CIMT与esRAGE和高密度脂蛋白胆固醇负相关,与年龄正相关.

Abstract：

The carotid initima-media thickness(CIMT)in 78 cases of type 2 diabetic patients was measured.The level of plasma endogenous secretion receptor for advanced glycation end-products(esRAGE)in patients with normal CIMT was higher than those with chickened CIMT[(0.257 3±0.165 6 vs 0.155 4±0.0701)μg/L,P<0.01].esRAGE was negatively associated with CIMT(r=-0.247,P<0.05).Logistic regression analysis showed that CIMT was negatively associated with esRAGE and hish density lipoprotein cholesterol,but was positively associated with age.     

慢性阻塞性肺疾病患者对氧磷酶和氧化应激与全身炎性反应的研究

Objective To analyze the activity of paraoxonase (PON1) and explore the relationship of PON1 and oxidative stress with systemic inflammation response in the acute exacerbation phase and stationary phase in patients with chronic obstructive pulmonary disease (COPD). Methods Serum PON1 activity was measured by phenylacetate in 38 patients with COPD and 30 healthy people. The activity of glutathione peroxidase (GSH-Px) was detected by improved Hafeman method. Total antioxidant capacity (TAC) was measured by eolorimetry and malondialdehyde (MDA) level was measured by thiobarbituric acid colouration method. The interleukin-6 (IL-6) and interleukin-8 (IL-8) levels were detected by radioimmunoassay. The level of C-reactive protein (CRP) was measured by immune turbidimetry. Results In the acute exacerbation phase, the activity of serum PON1 was significantly lower in COPD group than in control group [(98.03±42.40)×103U/L vs. (136.00±60. 50)×103U/L, t=4.962, P<0.01], and it was negatively related to the IL-8 level (r= - 0. 589, P<0.01) and positively related to FEV1% (r= 0. 434, P<0. 05). The activity of GSH-Px was negatively related to the IL-6 level (r=-0. 362, P< 0. 05). In the stationary phase of COPD group, the activity of serum PON1 had no statistical difference compared with control group[(131.50±53.65))×103U/L vs. (136. 00±60.50)×103U/ L, t=2. 457, P>0. 053, and it was negatively related to the IL-8 level (r=-0. 563, P<0.05). Conclusions Serum PON1 activity is significantly decreased in acute exacerbation phase of COPD group compared with control group and it is positively related to FEV1%. The oxidative stress is closely related to systemic inflammation response in patients with acute exacerbation of COPD.
