The editorial office reiterates the policy of Conflict of Interest！

For the sake of academic fairness, all authors are required to declare all activities that have the potential to be deemed as a source of competing interest in relations to their submitted manuscript. Examples of such activities could include personal or work-related relationships, events, etc. Authors who have nothing to declare are encouraged to add "The authors declare that there is no conflict of interest" in this section. A declaration of interests for all authors should be received before an article can be reviewed and accepted for the publication. As the authors, editors or reviewers, they also are required to declare the conflict of interest in academy.

For authors:

While submitting, authors must list all competing interests relevant to this work, including but not limited to:

• Funding sources
• The role of sponsors in the work design, data collection, and results of the analysis.
• Whether the author is serving on the editorial board of this journal submitting to.

For editors and reviewers:

Editors and reviewers must declare any possible conflict of interests in connection with the manuscript, and if necessary, they must avoid the peer review process. When Editorial Board Members publish articles in the served journal, the editorial office will actively emphasize it so that the authors know that they recuse the potential peer review process.

Common reasons for editors and reviewers to be replaced include but are not limited to:

• The editor or reviewer works at the same organization as one of the authors.
• The editor or reviewer is one of the authors of this work.
• The editor or reviewer is on the avoidance list from the author(s).
• The editor or reviewer has a financial relationship or personal relationship with an author.
