摘　　要：目的 探讨糖尿病合并下肢血管病变（DLEAD）患者血糖波动与踝肱指数（ABI）及8-异前列腺素F2α（8-iso-PGF2α）的相关性.方法 选择2013年9月～2014年2月北京军区总医院内分泌科收治的60例2型糖尿病（T2DM）患者,依据超声检查结果分为单纯2型糖尿病组（DM组）,合并下肢血管病变组（DLEAD组）,另选取健康者20例做为对照组（NC组）.分别检测其血压、血脂、糖化血红蛋白（HbA1c）、8-iso-PGF2α、ABI等指标.应用动态血糖监测仪对各组行连续72 h血糖监测,采用全天血糖标准差（SDBG）、日内平均血糖波动幅度（MAGE）、全天有效血糖波动次数（FGE）、日间血糖平均绝对差（MODD）4个指标评价血糖波动,比较三组间ABI、8-iso-PGF2α及各血糖波动参数,并分析血糖波动参数及临床生化指标与ABI、8-iso-PGF2α的相关性.结果 ①DLEAD组患者的病程、MAGE、MODD、SDBG、FGE、8-iso-PGF2α较DM组均明显升高,差异均有统计学意义（P＜0.05）;DLEAD组ABI明显低于DM组,差异有统计学意义（P＜0.05）.②采用Pearson相关分析表明：MAGE、FGE、MODD与ABI呈负相关（r=-0.802、-0.147、-0.553,P＜ 0.05）;MAGE、MODD与8-iso-PGF2α呈正相关（r=0.825、0.504,P＜0.05）.多因素逐步回归分析发现：MAGE、FGE、MODD与ABI独立相关（Y=1.26-0.046MAGE-0.017 FGE-0.042 MODD）.结论 血糖波动与DLEAD密切相关,可能是通过诱发氧化应激水平引起及加重DLEAD.Objective To investigate the relationship between the blood glucose fluctuations with ankle-brachial index （ABI） and 8-iso-prostaglandin 2α （8-iso-PGF2α） in type 2 diabetes patients （T2DM） with lower extremity vascular dis- ease. Methods From September 2013 to February 2014, in Department of Endocrinology of General Hospital of Beijing Military Command, 60 patients with T2DM undergone ultrasound scan were selected, 30 cases not merged with lower extremity vascular diabetes were as DM group, 30 cases merged with lower extremity vascular disease wete as DLEAD group, and 20 healthy people were as controls （group NC）. All the participants were monitored continuous glucose mon- itoring system （CGMS） for 72 hours to evaluate CGMS parameters such as mean amplitude of glycemic excursions （MAGE）, standard deviation of blood glucose （SDBG）, effective blood glucose fluctuations in frequency （FGE）, absolute means of daily differences （MODD）. The levels of 8-iso-PGF2α, ABI, blood pressure, blood fat, glycated hemoglobin （HbA lc） were detected. Then above-mentioned index were compared between the three groups. The correlation was ana- lyzed between the clinical biochemical, parameters with ABI, 8-iso-PGF2α. Results ①The levels of disease duration,The ABI of DLEAD group was statistically lower than that of the DM group. ②Pearson correlation analysis showed that： MAGE, MODD were positively related to 8-iso-PGF2α （r = -0.802, -0.147, -0.553, P 〈 0.05）. MAGE, FGE, MODD was negatively correlated with ABI （r = 0.825, 0.504, P 〈 0.05）. Multiple stepwise regression analysis indicated that MAGE, FGE, MODD were dependent risk to ABI （Y = 1.26-0.046MAGE-0.017FGE-0.042MODD）. Condusion Blood glucose fluctuations are closely correlated with DLEAD, and it may cause or aggravata DLEAD by inducing oxidative stress.
