摘要: 目的探讨阿尔茨海默病(AD)患者胰岛素及β淀粉样蛋白(Aβ)的异常代谢。方法随机选取70名正常人(对照组)、55例AD患者,检验其空腹血糖、真胰岛素、C肽、Aβ40、Aβ42水平。将AD患者按痴呆轻、中重度分组后与对照组进行比较。结果对照组比较,AD患者各组空腹血糖无显著性差异(P>0.05),中重度组真胰岛素和C肽升高(P<0.05),中重度组Aβ40升高(P<0.05),轻度组Aβ42明显升高(P<0.01)。结论AD患者体内存在胰岛素及β淀粉样蛋白代谢异常,其特征与痴呆的严重程度有关。

Abstract: Objective To investigate the level of insulin and amyloid beta-protein (Aβ) in patients with Alzheimer disease(AD). Methods The levels of fasting plasma glucose, true insulin, C-peptide, Aβ40 and Aβ42 in 70 healthy age-matched adults and 55 patients with AD were measured and analyzed. Results No differences were observed for the levels of fasting plasma glucose between AD groups and normal group (P>0.05). The level of the true insulin and C-peptide of the moderate/severe AD group were significantly higher than that of the normal control group(P<0.05), as well aw that of the Aβ40 (P<0.05). The level of Aβ42 of the mild AD group waw significantly higher than that of the normal control group(P<0.01). Conclusion Plasma insulin and Aβ are abnormal in AD, and they are related to severity of dementia.
