摘要: 目的 应用WCX磁珠联合MALDI-TOF MS 技术对肾血管平滑肌脂肪瘤进行血清差异蛋白实验,寻找显著性表达的差异蛋白,以提高肾血管平滑肌脂肪瘤的检出率。 方法 应用磁珠联合MALDI-TOF MS技术对肾血管平滑肌脂肪瘤血清进行差异蛋白研究,筛选出肾血管平滑肌脂肪瘤多个血清差异蛋白,并应用遗传算法建立诊断模型。结果 筛选出肾血管平滑肌脂肪瘤与对照组之间差异蛋白峰142个, 具有较明显差异的蛋白峰13个(P<0.05)。利用ClinProTools2.2软件通过遗传算法优化选择,筛选出符合条件的15个差异蛋白峰建立诊断模型,交叉验证识别能力为100%。结论 建立了肾血管平滑肌脂肪瘤血清差异蛋白的诊断模型,有助于提高肾血管平滑肌脂肪瘤的检出率。

Abstract: Objective The application of WCX magnetic beads combined with MALDI-TOF MS in detecting differentially expressed proteins in serum of renal angiomyolipoma can reduce the misdiagnosis rate. Methods WCX beads combined with MALDI-TOF MS technique in detecting differentially expressed proteins in serum of renal angiomyolipoma can screen out differentially expressed proteins. And genetic algorithm was utilized to establish a diagnosis model. Results The technique screened out 142 different protein, and 13 were significantly different (P<0.05). ClinProTools2.2 software was utilized with genetic algorithm to screen out 15 differentially expressed proteins to establish a diagnosis model. The recognition rate was 100%. Conclusions The iagnosis model established by the application of WCX magnetic beads combined with MALDI-TOF MS can reduce the misdiagnosis rate of renal angiomyolipoma.
