摘要
目的 探讨血清残粒样微粒胆固醇(RLP C)在糖尿病(DM)患者中的变化及其与糖尿病肾病(DN)的关系。方法 血清RLP C浓度用免疫分离法测定,同时测定血浆α 颗粒膜蛋白 (GMP140)和血清一氧化氮(NO)。尿 24h微量白蛋白用放免法测定,根据尿白蛋白排泄率 (UAER)将其分为 3组。结果96例 2型DM患者RLP C与 44例正常对照 (NC)比较显著升高〔(0. 281±0. 162)mmol/Lvs(0. 193±0. 125)mmol/L,P<0. 01〕,且 2型DM患者D1 组 (UAER<20μg/min)、D2 组 (UAER20 200μg/min)和D3 组(UAER>200μg/min)相比,RLP C浓度依次显著增加〔( 0. 225±0. 145 )mmol/L, ( 0. 292±0. 181 )mmol/L, (0. 363±0. 192)mmol/L〕。D2 和D3 组GMP140浓度显著高于D1 和NC组(均P<0. 01),NC组和D1 组NO均显著高于D2 和D3 组 (均P<0. 01)。RLP C与NO呈高度负相关 (r=-0. 75,P<0. 01 ),与UAER和GMP140呈高度正相关(r=0. 78和r=0. 81,均P<0. 01),NO与GMP140浓度呈高度负相关 (r=-0. 78,P<0. 01)。结论 RLP C浓度在 2型DM患者中显著增加,且在并发DN的 2型DM患者增加更显著,RLP C在DN的发生发展中具有致病作用,其机制可能是通过损伤血管内皮和活化血小板所致。
