摘要 目的 应用GlyPro酶法自动分析测定糖化血清蛋白(GSP),探讨GSP的临床应用。方法 评价genzymeGlyProGSP检测试剂盒的不精密度、分析范围、参考值与干扰实验。对50例正常健康个体、88例胰岛索抵抗(IR),176例2型糖尿病(DM)患者以及47例代谢综合征(MS)患者进行GSP检测,并对1275人进行了社区健康调查。结果 GlyPro酶法GSP检测试剂具有良好的精密度,批内、天间的不精密度分别为1.66%,2.38%(低值),1.42%,3.35%(高值)。GSP正常参考范围(204.32±35.41)μmol/L,95%可信区间为194.25~214.38μmol/L,线性检测范围至836.6μmol/L,能抵抗溶血及黄疸,24h内平均变异为10.49%:(1)胰岛素抵抗组,糖尿病组的GSP水平分别为(260.55±66.91)μmol/L,(393.74±154.84)μmol/L,明显高于正常对照人群水平(P〈0.01),且IR与DM两者之间也有非常显著的差异(P〈0.01)。血糖控制不佳的DM患者在平均16.6d治疗后,GSP由(407.65±137.48)μmol/L降至(314.72±83.56)μmol/L,GSP平均下降了20.4%(P〈0.01),它与FPG,2hPG的相关性达r=0.43I(P=0.005),r=0.515(P=0.001),同比HbAlC,GSP的下降更快、更直观,也更经济;(2)对某社区1275人进行的健康调查中有47例代谢综合征及65例DM患者,分别占总人群的3.69%与5.10%,将他们的性别、年龄、FPG、2hPG、BMI、腹围、臀围、收缩压、舒张压、TG、CHO、HDL—C、LDL-C及GSP分别与正常对照组比较,除性别、年龄与HDL.C无统计学差异外,其他均存在显著差别,其中MS组与DM组的GSP浓度分别为(359.98±138.67)μmol/L,(392.63±153.76)μmol/L,(P〈0.05),单独比较MS组与DM组,以上指标均无统计学差异(P〉0.05)。GSP与FPG,2hPG,TG,收缩压,舒张压,CHO显著相关,r依次为0.817,0.801,0.296,0.256,0.200,0.165(P〈0.05)。结论 GSP的检测方便,可靠,宜于自动化,GSP可成为胰岛素抵抗,糖尿病的病情监测,鉴别诊断与疗效判断的又一项指标。代谢综合征与DM患者等同于冠心病病人,被视为具多重危险的人群,GSP的测定能为MS的临床诊断与健康评价再提供一项新的内容。 Objective Determination of glycosylated serum protein(GSP) and other tests such as fasting plasma glucose(FPG), post prandial glucose (2hPG), glycosylated hemoglobin (HbAlc)for diabetes mellitus(DM), insulin resistance(IR), and metabolic syndrome(MS) patients, Methods Genzyme GlyPro GSP test and measurement of 50 normal people,88 insulin resistance, 176 type 2DM and 47 metabolic syndrome patients;1275 people who are living within a limited area run a routine health test. Results Genzyme GlyPro GSP test has good precision, within-run & without-run CV% are 1.66%, 2.38%(1ow),1.42%, 3.35% (high). It has large analytical range 70-836.6μmol/L, established reference range is (204.32±35.41)μmol/L (194.25±214.38μmol/L), and well anti-interference by the hemoglobin or bilirubin. Mean variation of GSP within 24 hours is 10.49%. GSP level of insulin resistance, (260.55 ± 66.91 )μmol/L, and type 2 DM patients, (393.74 ± 154.84)μmol/L or of the metabolic syndrome group, (359.98± 138.67)μmol/L, is much higher than it of normal people,(P〈0.01). Type 2DM patients without well control in GLU concentration will lower their GSP level, about 20.4%, after almost 16.6 days drug therapy (P〈0.01). GSP has very strong correlation with FPG, 2hPG, TG, systolic pressure, diastolic pressure and CHO, r=0.817,0.801, 0.296, 0.256, 0.200, 0.165 (P〈0.05) . Conclusion GSP will be a good test to monitor and judge of insulin resistance and DM, also it could be another useful test for the metabolic syndrome, especially for their interests in the progress of glycosylation & atherosclerosis.
