Erratum

After publication of this article [1] we were informed that the affiliation for Dr Yan Shi was incorrectly listed as Department of Medical Cosmetology, Jiangxi Maternal and Child Health Hospital. Dr Shi’s correct affiliation should have been given as Department of Burns Surgery, First Affiliated Hospital of Sun Yat-Sen University. Dr Shi’s affiliation has been corrected here.

Please note that the email address for Dr Bin Shu has changed since the publication of our original article. The correct e-mail address is shubin29@sina.com.
