摘要目的 探讨糖尿病患者颅内动脉狭窄与低血糖反应的关系.方法 选取我院2009年1月至2011年1月因脑动脉供血不足入院治疗的糖尿病患者,根据计算机断层扫描血管成像检查结果分为颅内动脉狭窄组和对照组,进行为期12个月随访,收集其间低血糖发生情况、低血糖发生时血糖水平等.采用t检验或卡方检验进行数据统计.结果 完成随访353例,共发生低血糖80例,其中对照组8例(14％),动脉狭窄组72例(38％),组间差异有统计学意义(P＜0.05).动脉狭窄组和对照组发生低血糖时平均血糖水平分别为(1.95+0.82)和(1.12±0.33) mmol/L,症状基本消失时间分别为(7.2±2.3)、(4.3±1.9)min,以神经低血糖症状为主要表现的比例分别为56％和33％,组间差异均有统计学意义(均P＜0.05).结论 伴有颅内动脉狭窄的糖尿病患者更容易出现低血糖反应,并且恢复时间更长.

abstractsObjective To explore the relationship between artery stenosis and hypoglycema among diabetic patients.Methods A total of 353 patients with cerebral arterial insufficiency underwent CT angiography in our hospital from January 2009 to January 2011.According the results,all the patients were assigned to the artery stenosis group or the control group and were then followed up for 12 months.Student's t test or Chi-square test was used for data analysis.Results Hypoglycemia was presented in 80 patients,including 72 in the artery stenosis group and 8 in the control group (38％ vs 14％,P ＜ 0.05).The average blood glucose level ((1.95 ± 0.82) vs (1.12 ± 0.33) mmol/L,P ＜ 0.05) and recovery time ((7.2 ±2.3) vs (4.3 ± 1.9) minutes,P ＜ 0.05) showed statistically significant difference between the two groups.Conclusion Diabetic patients with intracranial artery stenosis may have greater risk of hypoglycemia.
