本刊2014年第17卷第9期刊登的題為“Rap2a真核表達質粒的鑒定及其對肺癌細胞遷移能力的影響”[吳金霞, 桑苗苗, 曹文嘉, 等. Rap2a真核表達質粒的鑒定及其對肺癌細胞遷移能力的影響. 中國肺癌雜志, 2014, 17(9): 643-648.]一文中：第645頁圖1和第647頁圖6因作者失誤導致圖片錯誤，希望修正如下圖。特此更正。對此深表歉意。

圖1 Rap2a蛋白在肺癌細胞H1299和A549中的表達。A：Western blot檢測Rap2a蛋白在各組中的表達；B：Rap2a蛋白灰度分析。與HUVEC組比較：**P＜0.01 (n=3).Fig 1 Rap2a protein expression in H1299 and A549 cell lines. A: Western blot was used to analyze the expression of Rap2a protein; B: Densitometric analysis of Rap2a. The intensity of Rap2a was quantified by densitometry (software: Image J, NIH).Compared with HUVEC group: **P＜0.01 (n=3).

圖6 Rap2a過表達后明膠酶譜檢測細胞分泌MMP2的情況。A：明膠酶譜檢測細胞分泌MMP2情況；B：MMP2灰度分析。與vector組比較：**P＜0.01 (n=3).Fig 6 Gelatin zymography analysis of the relative enzyme activities of cleaved-MMP2 after overexpression of Rap2a. A: Gelatin zymography was used to analyze the expression of MMP2 after transfection with Rap2a; B:Densitometric analysis of MMP2. The intensity of MMP2 was quantified by densitometry (software: Image J, NIH).Compared with vector group: **P＜0.01 (n=3). MMP:matrix metalloproteinase.
