糖尿病是导致脑梗塞发生的主要危险因素之一，能增加脑梗塞的发病率．对我院30例糖尿病合并脑梗塞的病例进行分析，发现该组病人精基化血红蛋白的水平明显高于糖尿病对照组，P＜0．001，有显著性差异，提示糖尿病合并脑梗塞的发病可能和蛋白非酶糖化有关．因此，要预防脑梗塞的发生，关键在于控制好血糖．减少蛋白非酶糖化，尽可能将糖基化血红蛋白控制于理想水平． Diabetes is one of the major risk factors leading to cerebral infarction, which can increase the incidence of cerebral infarction. Analysis of 30 cases of diabetes mellitus with cerebral infarction in our hospital found that patients with sperm hemoglobin levels were significantly higher than the diabetic control group, P <0.001, there was a significant difference, suggesting that the incidence of diabetes mellitus with cerebral infarction may be And protein non-enzymatic glycation. Therefore, to prevent the occurrence of cerebral infarction, the key is to control the blood sugar. Decrease the non-enzymatic glycation of the protein and control the glycosylated hemoglobin to the ideal level as much as possible.
