This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted by the Editor-in-Chief because several results reported in the manuscript were plagiarized from the following article published in 2014 by Zhang et al.: Zhang Z, Zhang L, Zhou C, Wu H. Ketamine inhibits LPS-induced HGMB1 release in vitro and in vivo. Int Immunopharmacol 2014;23:14–26. The editor was contacted by the editor of International Immunopharmacology, who had been alerted regarding the presence of duplicate figures in the two articles. Examination of the articles confirmed that data in Figures 1, 2, and 11 in the paper by Wang et al. appeared to have been plagiarized from the paper by Zhang et al. The corresponding author of the paper by Wang et al. was not able to provide a satisfactory explanation or the original related data to refute the allegation.
