Retraction
The authors have retracted this article [1] because of significant overlap of text and some images with a previously published article by Xu et al. [2]. A formal investigation by the 1st Affiliated Hospital of Wenzhou Medical University has found that some panels in Fig. 6b [1] are identical with panels in Fig. 5a [2] and some images of mice lungs in Fig. 6c [1] are identical with images in Fig. 3g [2]. The data reported in this article are therefore unreliable. All authors agree to this retraction.
