The journal to which you are submitting your manuscript employs a plagiarism detection system. By submitting your manuscript to this journal you accept that your manuscript may be screened for plagiarism against previously published works.
AIMS AND SCOPE
Journal of Digestive Diseases is the official English language journal of the Chinese Society of Gastroenterology and the Chinese Medical Association Shanghai Branch. The Journal is produced four times per year and publishes peer-reviewed original papers, review articles and editorials concerned with research relating to the esophagus, stomach, small intestine, colon, liver, biliary tract and pancreas.
The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer reviewed by two anonymous reviewers and the Editor. The Editorial Board reserves the right to refuse any material for publication and advises that authors should retain copies of submitted manuscripts and correspondence, as material cannot be returned. Final acceptance or rejection rests with the Editorial Board.
Pre-acceptance English-language editing
Authors for whom English is a second language may choose to have their manuscript professionally edited before submission to improve the English. Visit our site to learn about the options. All services are paid for and arranged by the author. Please note using the Wiley English Language Editing Service does not guarantee that your paper will be accepted by this journal.
SUBMISSION OF MANUSCRIPTS
All articles submitted to the journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication. Manuscripts should be written so that they are intelligible to the professional reader who is not a specialist in the particular field. Where contributions are judged as acceptable for publication on the basis of scientific content, the Editor or the Publisher reserve the right to modify typescripts to eliminate ambiguity and repetition and improve communication between author and reader. If extensive alterations are required, the manuscript will be returned to the author for revision.
Prior to the submission of a manuscript, authors should familiarize themselves with and comply with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (www.icmje.org) relating to:
- Conflict of interest
- Protection of patients’ rights to privacy
- Redundant or duplicate publication
- Sponsorship, authorship and accountability
and provide a cover letter declaring that the content of the article has not been accepted or submitted for publication to any other journal. Authors should also declare any financial interests of relationships that may pose a conflict of interest.
The cover letter must also contain an acknowledgement that all authors have contributed significantly, and that all authors are in agreement with the content of the manuscript.
If tables or figures have been reproduced from another source, a letter from the copyright holder (usually the publisher), stating authorization to reproduce the material, must be attached to the cover letter.
In keeping with the latest guidelines of the International Committee of Medical Journal Editors, each author’s contribution to the paper is to be quantified.
The cover letter should be submitted with the manuscript.
Authors must also state within the Methods section of their article that:
- the protocol for the research project has been approved by a suitably constituted Ethics Committee of the institution within which the work was undertaken and that it conforms to the provisions of the World Medical Association’s Declaration of Helsinki in 1995 (as revised in Tokyo 2004), available at http://www.wma.net/e/policy/b3.htm
- informed consent has been obtained for all investigations on human subjects.
- any experiments involving animals conform to relevant national or institutional guidelines for animal usage in research.
- Failure to comply with these requirements may lead to automatic rejection of the submitted manuscript.
Effective from September 1st 2010, all manuscripts shall be submitted online via http://mc.manuscriptcentral.com/jdd
Author material archive policy
Authors who require the return of any submitted material that is accepted for publication should inform the Editorial Office after acceptance. If no indication is given that author material should be returned, Wiley will dispose of all hardcopy and electronic material two months after publication.
COPYRIGHT, LICENSING and ONLINE OPEN
Accepted papers will be passed to Wiley’s production team for publication. The author identified as the formal corresponding author for the paper will receive an email prompting them to login into Wiley’s Author Services, where via the Wiley Author Licensing Service (WALS) they will be asked to complete an electronic license agreement on behalf of all authors on the paper.

Preparation of the Manuscript
Submissions should be printed, doubled-spaced, on one side only of ISO A4 paper. The top, bottom and side margins should be at least 30 mm. Laser quality print is essential. All pages should be numbered consecutively in the top right-hand corner, beginning with the title page. Indent new paragraphs. Turn the hyphenation option off, including only those hyphens that are essential to the meaning.
Manuscripts should follow the style of the Vancouver agreement detailed in the International Committee of Medical Journal Editors' revised 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication', as presented at http://www.ICMJE.org/.
The journal uses US spelling and authors should therefore follow the latest edition of the Merriam-Webster’s Collegiate Dictionary. Please write in a clear, concise, direct style.
All measurements must be given in SI units.
Abbreviations should be used sparingly - only where they ease the reader’s task by reducing repetition of long, technical terms. Initially use the word in full, followed by the abbreviation in parentheses. Thereafter use the abbreviation only.
Upon its first use in the title, abstract and text, the common name of a species should be followed by the scientific name (genus, species and authority) in parentheses. However, for well-known species, the scientific name may be omitted from the article title. If no common name exists in English, the scientific name should be used only.
Drugs should be referred to by their generic names. If proprietary drugs have been used in the study, refer to these by their generic name, mentioning the proprietary name, and the name and location of the manufacturer, in parentheses.
Standard genetic nomenclature should be used. For further information, including relevant websites, authors should refer to the genetic nomenclature guide in Trends in Genetics (Elsevier Science, 1998).
Sequence Data Submission
Nucleotide sequence data can be submitted in electronic form to any of the three major collaborative databases: DDBJ, EMBL or GenBank. It is only necessary to submit to one database as data are exchanged between DDBJ, EMBL and GenBank on a daily basis. The suggested wording for referring to accession-number information is: ‘These sequence data have been submitted to the DDBJ/EMBL/GenBank databases under accession number U12345.’
PARTS OF THE MANUSCRIPT
Manuscripts should be presented in the following order: (i) title page, (ii) abstract and keywords, (iii) text, (iv) acknowledgments, (v) references, (vi) appendices, (vii) figure legends, (viii) tables (each table complete with legend and footnotes) and (ix) figures. Footnotes to the text are not allowed and any such material should be incorporated into the text as parenthetical matter.
The title page should contain (i) the title of the paper, (ii) the full names of the authors and (iii) the addresses of the institutions at which the work was carried out together with (iv) the full postal and email address, plus facsimile and telephone numbers, of the author to whom correspondence about the manuscript, proofs and requests for offprints should be sent. The present address of any author, if different from that where the work was carried out, should be supplied in a footnote.
The authors’ names should be listed as follows: personal name first, family name second, with family name in upper-case letters (e.g. Le Feng LIANG).
The title should be short, informative and contain the major key words. Do not use abbreviations in the title. A short running title (less than 40 characters, including spaces) should also be provided.
Abstract and key words
All articles must have a structured abstract that states in 250 words or fewer the purpose, basic procedures, main findings and principal conclusions of the study. Divide the abstract with the headings: Aim, Methods, Results, Conclusions. The abstract should not contain abbreviations or references.
Five key words, for the purposes of indexing, should be supplied below the abstract, in alphabetical order, and should be taken from those recommended by the US National Library of Medicine's Medical Subject Headings (MeSH) browser list: www.nlm.nih.gov/mesh/meshhome.html
Authors should use subheadings to divide the sections of their manuscript: Introduction, Methods, Results, Discussion, Acknowledgements, References. Do not number headings.
The source of financial grants and other funding must be acknowledged, including a frank declaration of the authors’ industrial links and affiliations. The contribution of colleagues or institutions should also be acknowledged. Personal thanks and thanks to anonymous reviewers are not appropriate.
The Vancouver system of referencing should be used. In the text, references should be cited using superscript Arabic numerals in the order in which they appear. If cited in tables or figure legends, number according to the first identification of the table or figure in the text.
Cite the names of all authors when there are six or fewer; when seven or more, list the first three followed by et al. Do not use ibid. or op cit. Reference to unpublished data and personal communications should not appear in the list but should be cited in the text only (e.g. Smith A, 2000, unpublished data). All citations mentioned in the text, tables or figures must be listed in the reference list. We recommend the use of a tool such as Reference Manager for reference management and formatting.
Reference Manager reference styles can be searched for here: http://www.refman.com/support/rmstyles.asp
Names of journals should be abbreviated in the style used in Index Medicus.

These should be placed at the end of the paper, numbered in Roman numerals and referred to in the text. If written by a person other than the author of the main text, the writer’s name should be included below the title.
Supporting Information can be a useful way for an author to include important but ancillary information with the online version of an article. Examples of Supporting Information include additional tables, data sets, figures, movie files, audio clips, 3D structures, and other related nonessential multimedia files. Supporting Information should be cited within the article text, and a descriptive legend should be included. It is published as supplied by the author, and a proof is not made available prior to publication; for these reasons, authors should provide any Supporting Information in the desired final format.
For further information on recommended file types and requirements for submission, please visit: http://authorservices.wiley.com/bauthor/suppinfo.asp
Tables should be self-contained and complement, but not duplicate, information contained in the text. Number tables consecutively in the text in Arabic numerals. Type tables on a separate sheet in double-spacing with the legend above. Legends should be concise but comprehensive - the table, legend and footnotes must be understandable without reference to the text. Vertical lines should not be used to separate columns. Column headings should be brief, with units of measurement in parentheses; all abbreviations must be defined in footnotes. Footnote symbols †, ‡, §, ¶,should be used (in that order) and *, **, *** should be reserved for P-values. Statistical measures such as SD or SEM should be identified in the headings. If tables have been reproduced from another source, a letter from the copyright holder, stating authorization to reproduce the table, must be sent to the Editorial Office with the manuscript.
All illustrations (line drawings and photographs) are classified as figures. Figures should be cited in consecutive order in the text. Each figure should be labeled on the back in very soft marker or chinagraph pencil, indicating name of author(s), figure number and orientation. Do not use adhesive labels as this precludes electronic scanning. Figures should be sized to fit within the column (82.5 mm), intermediate (112 mm) or the full text width (173.5 mm).
Line figures should be supplied as sharp, black and white graphs or diagrams, drawn professionally or with a computer graphics package; lettering must be included and should be sized to be no larger than the journal text.
Photographs should be supplied as sharp, glossy, black and white photographic prints and must be unmounted. Individual photographs forming a composite figure should be of equal contrast, to facilitate printing, and should be accurately squared.
Photographs need to be cropped sufficiently to prevent human subjects being recognized (or an eye bar should be used).
Magnifications should be indicated using a scale bar on the illustration.
If supplied electronically, graphics must be supplied as high resolution (at least 300 d.p.i.) files, saved as .eps or .tif. A high-resolution print-out must also be provided. Digital images supplied only as low-resolution print-outs and/or files cannot be used. Please visit our Digital Illustrations Standards web page at: http://authorservices.wiley.com/bauthor/digill.asp
Color photographs should be submitted as good quality, glossy color prints. A charge of RMB$2500 (Chinese authors)/US$400 (non-Chinese authors) for the first color page and RMB$1500 (Chinese authors)/US$250 (non-Chinese authors) for each extra color page thereafter will be charged to the author.
Type figure legends on a separate sheet in double-spacing. Legends should be concise but comprehensive - the figure and its legend must be understandable without reference to the text. Include definitions of any symbols used and define/explain all abbreviations and units of measurement. If figures have been reproduced from another source, a letter from the copyright holder, stating authorization to reproduce the figure, must be sent to the Editorial Office with the manuscript.
Authors should supply their accepted paper as formatted text. It is essential that the hardware and the word processing package are specified (e.g. IBM, Word 2000 or Mac, Word 5.1), as well as the first author’s surname, the journal title and the manuscript number.
The entire article (including tables) should be supplied as a single file; only electronic figures should be supplied as separate files.
The following instructions should be adhered to:
- It is essential that the final, revised version of the accepted manuscript and the file saved on disk are identical.
- Do not use the carriage return (enter) at the end of lines within a paragraph.
- Turn the hyphenation option off.
- Specify any special characters used to represent non-keyboard characters.
- Take care not to use l (ell) for 1 (one), O (capital o) for 0 (zero) or ß (German esszett) for β (Greek beta).
- Use letters to type roman numerals, for example type ‘I’ twice for ‘2’ in roman numerals.
- Do not use Chinese punctuation: avoid ‘。’ and ‘、’, instead use ‘.’ and ‘ ,’, respectively.
- Use a tab, not spaces, to separate data points in tables.
- If you use a table editor function, ensure that each data point is contained within a unique cell, i.e. do not use carriage returns within cells.
- Digital figures must be supplied as .tif or .eps files at a resolution of at least 300 d.p.i. (high-resolution print-outs are also required).

It is essential that corresponding authors supply an email address to which correspondence can be emailed while their article is in production.
(1) Proofs of the edited articles will be sent via e-mail, as PDF files, and should be returned to the sender within 3 days of receipt. It is essential that the proofs are checked carefully, as the cost of changes made at a later stage may be charged to the author. Full instructions on how to correct and return the proof will be attached to the email.
(2) After the Word file proof has been checked, notification of the URL from where to download a PDF (Portable Document Format) typeset page proof, associated forms and further instructions will be sent by email to the corresponding author. The purpose of the PDF proof is as a final check of the layout, tables and figures. Alterations (other than the essential correction of errors) are unacceptable at PDF stage. Acrobat Reader is required to read the PDF. This software can be downloaded (free of charge) from the following web site: www.adobe.com/products/acrobat/readstep2.html. The proof should be checked, and approval to publish the article should be emailed to the Publisher by the date indicated; otherwise, it may be held over to the next issue.
A minimum of 50 printed offprints will be provided upon request, at the author’s expense. These paper offprints may be ordered online. Please visit http://offprint.cosprinters.com/, fill in the necessary details and ensure that you type information in all of the required fields. If you have queries about offprints please email firstname.lastname@example.org
'Accepted Articles' have been accepted for publication and undergone full peer review but have not been through the copyediting, typesetting, pagination and proofreading process. Accepted Articles are published online a few days after final acceptance, appear in PDF format only (without the accompanying full-text HTML) and are given a Digital Object Identifier (DOI), which allows them to be cited and tracked. The DOI remains unique to a given article in perpetuity. More information about DOIs can be found online at http://www.doi.org/faq.html. Given that Accepted Articles are not considered to be final, please note that changes will be made to an article after Accepted Article online publication, which may lead to differences between this version and the Version of Record.
The Accepted Articles service has been designed to ensure the earliest possible circulation of research papers after acceptance. Given that copyright licensing is a condition of publication, a completed copyright form is required before a manuscript can be processed as an Accepted Article.
Accepted articles will be indexed by PubMed; therefore the submitting author must carefully check the names and affiliations of all authors provided in the cover page of the manuscript, as it will not be possible to alter these once a paper is made available online in Accepted Article format. Subsequently the final copyedited and proofed articles will appear in an issue on Wiley Online Library; the link to the article in PubMed will automatically be updated.
Prior to acceptance there is no requirement to inform an Editorial Office that you intend to publish your paper OnlineOpen if you do not wish to. All OnlineOpen articles are treated in the same way as any other article. They go through the journal’s standard peer-review process and will be accepted or rejected based on their own merit.
