Tianjin Medical Journal 2016;44(7):902-905
Objective To explore the correlation between serum homocysteine (Hcy) level and diabetes mellitus combined with cerebral infarction (DMCI) in patients. Methods A total of 144 patients with type 2 diabetes mellitus (T2DM) were selected and divided into two groups, patients without cerebral infaction (group A, n=64) and patients with cerebral infaction (group B, n=80). Thirty healthy people were used as control group (group C). The serum Hcy level was detected by enzymatic cycling assay in three groups. The serum levels of cholesterol (TC) and triglyceride cholesterol (TG) were detected by enzymatic determination. The serum levels of high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by homogeneous phase method. The serum level of creatinine (Cr) was detected by creatine oxidase method. The level of uric acid (UA) was detected by urinary enzyme peroxidase coupling method. Glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. The carotid artery intima media thickness (IMT) was examined by color Doppler ultrasound, and patients were divided into mild and no stenosis group, moderate stenosis group and severe stenosis group according to the
results. The levels of Hcy were compared between all groups. The correlation of Hcy level and other indicators was analyzed. Results The levels of Hcy and HbA1c were group C
