摘　　要：目的分析miRNA-let-7联合血清标志物对多形性胶质母细胞瘤(GBM)患者化疗效果和预后的预测效果。方法收集25例GBM患者临床资料。纳入同期20名健康志愿者作为对照组。收集患者空腹血清样本,通过实时定量PCR分析血清样本中let-7b、let-7d以及let-7e水平。结果与对照组相比,GBM组患者外周血中let-7b(192.50±18.71 vs.98.13±11.68,t=6.42,P<0.0001)、let-7d(82.97±14.14 vs.44.62±6.83,t=2.41,P<0.05)以及let-7e(139.60±14.62 vs.75.86±9.72,t=5.45,P<0.001)水平显著降低。let-7b、let-7e水平在≥60岁、肿瘤大小≥5 cm、非额颞叶病变、ECOG为2、仅接受活检的GBM患者中显著降低(P<0.05)。此外,Let-7b、Let-7e水平在不同治疗反应的GBM患者中差异有统计学意义(P<0.05)。let-7b和let-7e高表达GBM患者的OS显著高于let-7b和let-7e低表达患者(P<0.05)。结论血液样品中的let-7b、let-7e表达可用于监测GBM、预测患者对治疗的反应和预后。Objective To analyze the predictive effect of miRNA-let-7 combined with serum markers on the chemotherapy effect and prognosis of glioma(GBM)patients.Methods We collected the data of 25 patients with GBM.Twenty healthy volunteers were included as the control group.Fasting serum samples were collected.The levels of let-7b,let-7d,and let-7e in serum samples were analyzed by quantitative real-time PCR.Results Compared with the control group,the levels of let-7b(192.5±18.71 vs.98.13±11.68,t=6.42,P<0.0001)and let-7d(82.9±14.14 vs.44.62±6.83,t=2.41,P<0.05)and let-7e(139.60±14.62 vs.75.86±9.72,t=5.45,P<0.001)in the peripheral blood of patients in the GBM group decreased significantly.The let-7b and let-7e levels significantly decreased in GBM patients over 60 years old,with tumor size over 5 cm,nonfrontotemporal lesions,and ECOG of 2,who underwent biopsy alone(P<0.05).The levels of let-7b and let-7e significantly differed among GBM patients with various types of treatment response(P<0.05).The OS of GBM patients with high expression of let-7b and let-7e was higher than that of patients with low let-7b and let-7e expression(P<0.05).Conclusion The expression of let-7b and let-7e in blood samples can be used to monitor GBM and predict patients'response to treatment and prognosis.
