文题释义:
α-硫辛酸:
是一种天然的强抗氧化剂,可以清除机体生理和病理过程中的各种自由基,减轻机体氧化应激。2型糖尿病患者内皮祖细胞功能障碍主要由一氧化氮系统引起,而α-硫辛酸能够改善其抗氧化能力及一氧化氮的分泌,从而保护内皮祖细胞功能。
内皮祖细胞:是血管内皮细胞的前体细胞,在生理或病理因素刺激下,可从骨髓动员到外周血参与损伤血管的修复。1997年,Asahara等首次证明循环外周血中存在能分化为血管内皮细胞的前体细胞,并将其命名为血管内皮祖细胞。研究显示,内皮祖细胞在心脑血管疾病、外周血管疾病、肿瘤血管形成及创伤愈合等方面均发挥重要作用,并为缺血性疾病的研究治疗提供了新思路。

 

摘要
背景:
前期研究表明,初诊2型糖尿病患者已存在血管内皮功能障碍,α-硫辛酸作为一种抗氧化剂,广泛应用于糖尿病神经病变患者,而其能否改善初诊2型糖尿病患者循环内皮祖细胞的数量与功能,目前尚无这方面的研究。
目的:探讨α-硫辛酸对初诊2型糖尿病患者循环内皮祖细胞水平的影响。
方法:将50例初诊2型糖尿病患者在基础治疗的前提下,随机分为对照组20例和α-硫辛酸组30例,治疗前和治疗2周检测超氧化物歧化酶、谷胱甘肽过氧物酶、丙二醛、8-羟基脱氧鸟苷、三酰甘油、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇水平及内皮祖细胞数量,分析各指标在两组间的差异及相关性。
结果与结论:①与治疗前比较,α-硫辛酸组治疗后内皮祖细胞数量、超氧化物歧化酶、谷胱甘肽过氧物酶活性显著增加(P < 0.05),丙二醛、8-羟基脱氧鸟苷、三酰甘油、总胆固醇、低密度脂蛋白胆固醇显著降低(P < 0.05),高密度脂蛋白胆固醇显著升高(P < 0.05);②与治疗前比较,对照组治疗后三酰甘油、总胆固醇、低密度脂蛋白胆固醇显著下降(P < 0.05),高密度脂蛋白胆固醇显著升高(P < 0.05);③两组治疗前后的差值比较:α-硫辛酸组较对照组内皮祖细胞数量、超氧化物歧化酶、谷胱甘肽过氧物酶活性显著增加(P < 0.05),丙二醛、8-羟基脱氧鸟苷含量显著降低(P < 0.05);④以α-硫辛酸组治疗前后各指标的差值进行多元线性回归分析显示,谷胱甘肽过氧物酶、丙二醛是内皮祖细胞水平的影响因素;⑤结果表明,α-硫辛酸能够通过抗氧化应激增加初诊2型糖尿病患者循环内皮祖细胞水平。

Abstract:

BACKGROUND: Previous studies have shown that vascular endothelial dysfunction exists in patients with newly diagnosed type 2 diabetes. Alpha-lipoic acid is widely used as an antioxidant in patients with diabetic neuropathy. Can it improve the number of circulating endothelial progenitor cells in newly diagnosed type 2 diabetic patients? There is no such report.
OBJECTIVE: To investigate the impact of α-lipoic acid on circulating endothelial progenitor cells in newly diagnosed type 2 diabetes mellitus. 
METHODS: Fifty newly diagnosed type 2 diabetes mellitus patients were randomly divided into control group (n=20) and alpha-lipoic acid group (n=30). Superoxide dismutase, glutathione peroxidase, malondialdehyde, 8-hydroxydeoxyguanosine, triacylglycerol, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol levels and number of endothelial progenitor cells were detected in the two groups before and 2 weeks after treatment. The differences and correlations between the two groups were analyzed.
RESULTS AND CONCLUSION: In the alpha-lipoic acid group, the number of endothelial progenitor cells, superoxide dismutase, glutathione peroxidase and high-density lipoprotein cholesterol levels were significantly increased after treatment compared with the baseline (P < 0.05), while the levels of malondialdehyde, 8-hydroxydeoxyguanosine, triacylglycerol, total cholesterol and low-density lipoprotein cholesterol were significantly decreased after the treatment (P < 0.05). In the control group, the levels of triacylglycerol, total cholesterol and low-density lipoprotein cholesterol were significantly reduced after treatment compared with the baseline (P < 0.05), while the level of high-density lipoprotein cholesterol increased significantly after treatment (P < 0.05). Compared with the control group, the number of endothelial progenitor cells, superoxide dismutase and glutathione peroxidase levels were significantly increased in the alpha-lipoic acid group (P < 0.05), while the levels of malondialdehyde and 8-hydroxydeoxyguanosine were decreased in the alpha-lipoic acid group (P < 0.05). Multivariate linear regression analysis of the differences of the indexes before and after treatment in the alpha-lipoic acid group showed that the number of endothelial progenitor cells was correlated with the levels of glutathione peroxidase and malondialdehyde. To conclude, the treatment with α-lipoic acid increases the number of circulating endothelial progenitor cells in newly diagnosed type 2 diabetes mellitus, which is associated with antioxidative stress.
