RETRACTED: Tanshinone IIA exerts beneficial effects on fracture healing in vitro and in vivo

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. There were serious questions about the validity of the data contained in these articles: "... the Western blot bands in ... papers are all very regularly spaced and have a smooth appearance in the shape of a dumbbell or tadpole, without any of the usual smudges or stains. All bands are placed on similar looking backgrounds, suggesting they were copy/pasted from other sources, or computer generated". Based on the latter findings, the Editor-in-Chief requested the authors to provide the raw data. However, the authors were not willing and/or able to fulfil this request and therefore the Editor-in-Chief decided to retract the article. As a consequence the writing in this article misled and deceived reviewers and readers of the journal and thus as a whole represents a gross misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
