Abstract:

ObjectiveTo investigate the relationship between homocysteine level and type 2 diabetes mellitus with mild cognitive impairment in middle-aged and elderly patients.MethodsA total of 121 middle-aged and elderly patients with type 2 diabetes who were admitted to the Department of Endocrinology of the Second Affiliated Hospital of Shandong First Medical University from November 1, 2022 to September 30, 2023 were selected. 59 patients were divided into 59 cases of normal homocysteine group (≤ 15 μmol/L) and 62 were deivided into homocysteine elevated group (> 15 μmol/L) according to the serum homocysteine level, Their cognitive function was assessed and compared according to the MMSE and ADL.ResultsCompared with patients with normal homocysteine, patients with elevated homocysteine had a significantly higher rate of mild cognitive impairment, with a statistically significant difference (P< 0.001). In the terms of the total score of MoCA scale, compared with the homocysteine normal group, the total score of MoCA scale in the homocysteine elevated group was significantly lower, and the difference was statistically significant (P< 0.001). In the terms of visual space and executive function, naming, delayed recall, the scores of patients of the homocysteine elevated group were significantly lower than that of the homocysteine normal group, the difference was statistically significant (P< 0.001).In the terms of attention, language and orientation, patients of the homocysteine elevated group scored significantly lower than the homocysteine normal group, the difference was statistically significant (P< 0.05).In the terms of abstraction, there was no statistically significant difference in the scores of patients between the homocysteine normal group and the homocysteine elevated group (P> 0.05).Conclusion1. Homocysteine is negatively correlated with the total score of the Montreal Cognitive Function Assessment Scale, and it is a risk factor for type 2 diabetes with mild cognitive impairment. 2. Elevated plasma homocysteine had significant effects on visuospatial and executive function, naming, delayed recall, attention, language, and orientation, especially on naming and delayed recall, but had no effect on abstract function.

摘要:

目的探讨同型半胱氨酸水平与中老年2型糖尿病合并轻度认知功能障碍之间的关系。方法选择2022年11月1日—2023年9月30日在betway必威登陆网址 第二附属医院内分泌科就诊的中老年2型糖尿病患者121例,根据血浆同型半胱氨酸水平,将患者分为同型半胱氨酸正常组(≤ 15 μmol/L)59例、同型半胱氨酸升高组(> 15 μmol/L)62例;采用简易智力状态检查量表和蒙特利尔认知评估量表(Montreal cognitive assessment, MoCA)对各组患者进行认知功能评定并比较。结果与同型半胱氨酸正常组患者相比,同型半胱氨酸升高组患者中存在轻度认知功能障碍的比例明显较高,差异具有统计学意义(P< 0.001)。在MoCA量表总分方面,与正常组相比较,同型半胱氨酸升高组患者的MoCA量表总分明显降低,差异具有统计学意义(P< 0.001);在视空间与执行功能、命名、延迟回忆方面,同型半胱氨酸升高组患者得分均明显低于正常组,差异均具有统计学意义(P< 0.001);在注意、语言、定向方面相比,同型半胱氨酸升高组患者得分均明显低于正常组,差异具有统计学意义(P< 0.05);在抽象方面,同型半胱氨酸升高组患者得分与正常组相比,差异无统计学意义(P> 0.05)。结论同型半胱氨酸水平与蒙特利尔认知功能评估量表总分呈负相关,是2型糖尿病合并轻度认知功能障碍的危险因素。血浆同型半胱氨酸升高对认知功能中的视空间与执行功能、命名、延迟回忆、注意、语言、定向这些方面存在影响,尤其是命名以及延迟回忆方面影响较为显著,而对抽象功能无影响。
