Neurology: 血浆裂解晚期糖基化终末产物受体(cRAGE)水平可预测急性脑缺血患者的预后

2016-04-03 MedSci MedSci原创

目的:为了研究内源性分泌RAGE(esRAGE)和裂解的RAGE(cRAGE)这两种可溶性晚期糖基化终末产物受体(RAGE)与急性缺血性脑卒中(IS)预后的相关性。方法:招募急性缺血性脑卒中病人106人及年龄和性别匹配的对照组患者 150人。应用ELISA检测患者急性缺血卒中发生后48h内和48-72h内血浆总sRAGE和esRAGE的水平。同样也用ELISA检测对照组人群的血浆总sRAGE和es

目的:为了研究内源性分泌RAGE(esRAGE)和裂解的RAGE(cRAGE)这两种可溶性晚期糖基化终末产物受体(RAGE)与急性缺血性脑卒中(IS)预后的相关性。

方法:招募急性缺血性脑卒中病人106人及年龄和性别匹配的对照组患者 150人。应用ELISA检测患者急性缺血卒中发生后48h内和48-72h内血浆总sRAGE和esRAGE的水平。同样也用ELISA检测对照组人群的血浆总sRAGE和esRAGE的水平。esRAGE水平减去sRAGE水平得出cRAGE的浓度水平。在卒中后三个月,mRS分数>2定义为预后不良。

结果:cRAGE血浆浓度明显升高,且与esRAGE血浆浓度相关联(p < 0.001)。与对照组相比,IS患者发病后48h内和48-72内,esRAGE和cRAGE血浆浓度明显升高。但校正临床变量后,仅发病48h内cRAGE血浆浓度与不良预后独立关联(OR 2.44; 95% CI 1.16-5.16; p = 0.019)。

结论:在IS后48h内,cRAGE血浆浓度而不是esRAGE,是急性IS预后的重要预测指标。
