  目的:本课题组前期对放射性颌骨坏死(ORNJ)患者应用蛋白质组学筛查和鉴定出α2-巨球蛋白(α2M)等十二种血清差异蛋白,并应用酶联免疫吸附试验(ELISA法)验证,发现α2M可作为ONJ血清学标志物.在此基础上,本实验探讨鼻咽癌患者放疗后期血清α2M水平变化及其临床意义,为血清α2M在ORNJ诊治中的应用提供进一步依据.方法:采用ELISA法,对30例初治鼻咽癌患者放疗前、接受放疗剂量50Gy、接受放疗剂量70Gy及20例健康献血者血清中α2M水平进行检测和对比.结果: 1.初治鼻咽癌患者放疗前血清α2M水平与健康对照组无显著差异(P>0.05);鼻咽癌患者放疗前血清α2M水平在性别、年龄、临床分期间无差异(P>0.05);2.与放疗前及接受放疗剂量50Gy比较,接受放疗剂量70Gy后血清α2M水平明显升高(P<0.01);较放疗前,接受放疗剂量5Gy血清α2M水平无显著差异(P>0.017).结论:1.初治鼻咽癌患者血清α2M水平在正常范围内;血清α2M水平与患者性别、年龄、肿瘤临床分期无关.2.本研究结果表明,鼻咽癌放疗患者血清α2M水平与放疗剂量的增大有正相关趋势,提示血清α2M可能是观测放疗对颌骨的损伤的早期指标之一,应进行更深入、系统的观察研究.3.在本课题组过往有关ORNJ骨代谢标志物系列研究基础上,结合本实验发现,进一步提示血清α2M对颌骨放射性损伤可能起到保护作用,其中机制很有必要深入研究.
