Objective: To study the relationship of Nε-(carboxymethyl)-lysine level (CML) with microstructure changes of white matter (WM), and cognitive impairment in patients with type 2 diabetes mellitus (T2DM) and to discuss the potential mechanism underlying T2DM-associated cognitive impairment. Methods: The study was performed in T2DM patients (n=22) with disease course ≥5 years and age ranging from 65 to 75 years old. A control group consisted of 25 sex- and age-matched healthy volunteers. Fractional anisotropy (FA) of several WM regions was analyzed by diffusion tensor imaging scan. Plasma CML levels were measured by enzyme-linked immunosorbent assay, and cognitive function was assessed by Mini-Mental State Examination and Montreal cognitive assessment (MoCA). Results: The total Mini-Mental State Examination score in the patient group (25.72±3.13) was significantly lower than the control group (28.16±2.45) (p<0.05). In addition, the total MoCA score in the patient group (22.15±3.56) was significantly lower than the control group 25.63±4.12) (p<0.01). In the patient group, FA values were significantly decreased in the corpus callosum, cingulate fasciculus, inferior fronto-occipital fasciculus, parietal WM, hippocampus, and temporal lobes relative to corresponding regions of healthy controls (p<0.05). Plasma CML level was negatively correlated with average FA values in the global brain (r=−0.58, p<0.01) and MoCA scores (r=−0.47, p<0.05). Conclusions: In T2DM, WM microstructure changes occur in older patients, and elevations in CML may play a role in the development of cognitive impairment.

In light of the growing popularity of the use of computer management systems (CMSs) in higher education today, this study critically evaluates CMS adoption through a content-specific lens. By employing a mixed-method approach, the study examines college teachers’ and students’ experiences and perceptions of CMS adoption for language learning and teaching purposes. The findings show that despite the users’ perceived advantages of using CMSs in language courses, the systems’ lack of content-area specificity undermines many of the potential benefits. The study calls for better-rounded professional training to assist language teachers in integrating CMS functions strategically into their disciplinary pedagogy and incorporating multimedia language resources selectively to maximize the benefit of CMSs. Furthermore, the findings demonstrate the importance of developing content-specific CMSs with functions tailored toward pedagogical needs in different contexts.
