Following the publication of the original article [1], the authors notified us that the affiliation for Peiwu Li should remain the Department of Spleen and Stomach Diseases... (affiliation number 2). However, this affiliation should be removed for for Mingying Zhang, Changsong Lin and Xiangwei Yang, as it was mistakenly added during proofs. The correct affiliation for Mingying Zhang, Changsong Lin and Xiangwei Yang should be affiliation number 1.

The original article has been corrected.
