Methods We enrolled 27 patients with DLBCL and 27 healthy controls for the study. The plasma level of miR-451 was detected by reverse transcription polymerase chain reaction (RT-PCR). Then we analyzed the relationship between the plasma level of miR-451 and pathological characteristics of DLBCL. Results The plasma level of miR-451 in the patients with DLBCL was significantly lower than in healthy controls [(0.41±0.15) vs. (0.64±0.21)] (P<0.01). However, the plasma level of miR-451 was not significantly correlated with the patients?? gender, age, serum LDH level or primary site (P>0.05), but with Ann Arbor tumor stage and IPI score (P<0.05). Conclusion The plasma level of miR-451 decreases in patients with DLBCL, which indicates that miR-451 may participate in the pathology of DLBCL %K 弥漫性大B细胞淋巴瘤 %K microRNA-451 %K 定量PCR< %K br> %K diffuse large B lymphoma %K microRNA-451 %K RT-PCR %U http://yxxb.xjtu.edu.cn//oa/darticle.aspx?type=view&id=201604029
