一般注意事项:
GASTROENTEROLOGY publishes clinical and basic studies of all aspects of the digestive system, including the liver and pancreas, as well as nutrition. The types of articles GASTROENTEROLOGY publishes include original papers, review articles, and special category manuscripts. Manuscripts must be prepared in accordance with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" developed by the International Committee of Medical Journal Editors (   http://www.icmje.org ). Gastroenterology is a member of the Committee on Publication Ethics (COPE) (  http://www.publicationethics.org.uk ). 

GASTROENTEROLOGY strongly encourages the submission of papers on a breadth of clinical topics in gastroenterology, hepatology, and endoscopy, especially randomized controlled trials (phases II-IV but typically not phase I), high-quality observational studies, and novel case series. GASTROENTEROLOGY is interested in all aspects of clinical trials including treatment, prevention, diagnosis, screening and quality of life. High-quality meta-analyses are also welcome. Publication priority will be determined by factors such as novelty, impact upon clinical practice, strength of the experimental design and mechanistic insight.

GASTROENTEROLOGY is interested in all aspects of high impact translational and basic studies that would be of interest to our broad readership. These aspects include defining a critical physiologic or disease process/pathway, or mechanism for disease progression or protection; identifying a genetic cause, modifier or association with disease; describing a novel experimental disease model; characterizing a novel GI-related mechanism of drug action; preclinical studies that describe a potential novel therapy, diagnostic or prognostic marker or tool that is related a disease.

GASTROENTEROLOGY has a total circulation of approximately 17,000—about 12,000 in the United States and 5,000 in other countries. Eighty percent of subscribers are AGA members. In the United States, about 75% of subscribers are physicians, and about 25% of subscriptions go to residents, medical schools, and libraries. About 68% of the papers published originate overseas. 

GASTROENTEROLOGY is abstracted and indexed in Biological Abstracts, CABS, Chemical Abstracts, Current Contents, Excerpta Medica, Index Medicus, Nutrition Abstracts, and Science Citation Index.

ETHICAL STANDARDS 

GASTROENTEROLOGY strongly discourages the submission of more than one article dealing with related aspects of the same study. In almost all cases, a single study is best reported in a single paper.

The Journal editors consider research/publication misconduct to be a serious breach of ethics and will take action as necessary to address such misconduct, which includes submission or publication of information that:

(1) Is intentionally erroneous, 
(2) Has been published elsewhere by a different author without acknowledgment (plagiarism), 
(3) Has been published elsewhere by the same author without acknowledgment (duplicate publication), or 
(4) Is subsequently published elsewhere by the same author without acknowledgment, attribution, or permission from the AGA Institute, as holder of the copyright, to reprint or adapt the material. 

Each author who submits a manuscript to GASTROENTEROLOGY must attest to several author statements in the manuscript management system, thereby assigning copyright of the manuscript to the AGA Institute and affirming authorship responsibility, manuscript originality, payment of author fees, IRB/Animal Care Committee approval, role of study sponsor, financial disclosures, and funding sources. 

Breaches of GASTROENTEROLOGY's ethical standards may result in proscribed submission for all authors of the concerned manuscript and, when appropriate, notification of the authors' institutions. All authors are fully responsible for the content of the manuscript. 

Animal experiments: Studies involving animal experiments should conform to the Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines (www.nc3rs.org.uk/ARRIVE), developed by the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) to improve standards and reporting of animal research. Please review the ARRIVE checklist and disclose all relevant animal research information as directed. 

The publication of abstracts or posters is not considered duplicate publication but should be disclosed in the cover letter accompanying the manuscript submission. 

Authorship 
Each author must have participated sufficiently in the work to take public responsibility for the content of the paper and must approve of the final version of the manuscript. Authorship should be based on substantive contributions to each of the following: 

(1) conception and design of the study; 
(2) generation, collection, assembly, analysis and/or interpretation of data; 
(3) drafting or revision of the manuscript; 
(4) approval of the final version of the manuscript. 

CONFLICT OF INTEREST POLICY (COI)

A. Potential Conflicts of Interest
The following are examples of COI that may occur with editors, authors (including invited authors), and reviewers. Interactions considered pertinent are from the start of the research activity in a specific program until such time that a submission is anticipated to be published or one year from submission date, whichever is longer. 
a. Editors: Editors who make final decisions about manuscripts must have no personal, professional, or financial involvement in any of the issues they might judge. Examples of personal involvement with an author include former student, fellow, mentor, or relative. Examples of professional involvement include academic rivalry, being from the same institution or research group as the author, evaluating a manuscript submitted by a member of the board of editors, or collaborating (e.g., co-authoring research article or grant) with an author. Examples of financial involvement include employment, consultancies, honoraria, stock ownership or options, expert testimony, grants/patents received, and royalties with an entity (or competing entity) discussed in the manuscript. 

It is a COI for editors of the AGA Institute journals to hold a position of editorial responsibility for a competing publication. The Ethics Committee reviews disclosure statements submitted by editors and notifies either/both the Secretary/Treasurer and editor of any potential conflicts. The procedures contained in Section C of the "AGA/AGA Institute Policy on Disclosure of Potential Conflict of Interest" apply if a conflict is found to exist. 

b. Authors: COI for an author may arise if there exists a financial arrangement (e.g., employment, consultancies, honoraria, stock ownership or options, expert testimony, grants/patents received, and royalties) with a company whose product figures prominently in the submitted manuscript or with a company that makes a competing product. 

c. Reviewers: COI for reviewers exist when they have had an ongoing collaboration, original publications, or grants with the authors within the previous two years, except when part of a multicenter group from a different site; are from the same institution as the authors; or have any financial arrangements (e.g., employment, consultancies, honoraria, stock ownership or options, expert testimony, grants/patents received, and royalties) with a company whose product figures prominently in the submitted manuscript or with a company that makes a competing product.


B. Process
Potential COI are to be disclosed at the beginning of the peer-review process. 


a. Editors: An associate editor having COI with a submitted manuscript must recuse himself from handling the manuscript and request that the manuscript be reassigned. The editor-in-chief having COI with a submitted manuscript must assign review to one of an associate or guest editor for handling. A manuscript submitted by one of the members of the board of editors must be assigned to a guest editor. 

b. Authors: The senior or corresponding author assumes full responsibility for supplying the following information on the title page at manuscript submission: 
i. For each author, disclosure of any financial arrangement with any company whose product figures prominently in the submitted manuscript or that makes a competing product; or a statement for each author that there is no conflict to disclose. 
ii. A disclosure of all funding sources supporting the work and all institutional or corporate affiliations. 
iii. A list of individuals who provided writing assistance for the manuscript and the source of funds that supported this assistance. 

In addition, at manuscript submission, each author must attest to several author statements in the manuscript management system, thereby assigning copyright of the manuscript to the AGA Institute and affirming authorship responsibility, manuscript originality, payment of author fees, IRB/Animal Care Committee approval, role of study sponsor, financial disclosures, and funding sources. 

Based on the information provided, the editors will determine whether COI exists and decide to either a) reject the manuscript or b) publish the manuscript with the COI disclosed. 

c. Reviewers: When invited, reviewers must decline to review a manuscript if a potential COI exists. After review, reviewers must answer the following questions, which appear in the journals' manuscript tracking system: 
i.Have you, the undersigned Reviewer, had an ongoing collaboration, original publication or grant with the authors within the previous two years, except in the case of being a part of a multi-center group from a different site?
ii. Are you, the undersigned Reviewer, from the same institution as the authors?
iii.Do you, the undersigned Reviewer, have any financial arrangements (eg, employment, consultancies, honoraria, stock ownership or options, expert testimony, grants/patents received, and royalties with an entity) with a company whose product figures prominently in the submitted manuscript or with a company making a competing product? Any reviewer answering "yes" to question 3 is prompted to describe the nature of their financial agreements. 

If the reviewer discloses a potential COI after the review, the handling associate editor decides if the review should still be used to judge the manuscript.


C. Sanctions
Should an editor, author, or reviewer fail to disclose a potential COI and this is discovered after publication, the following sanctions may be applied according to the severity of the infraction. 


a. Editors: 
i. A letter of reprimand and warning as to future conduct from the editor, in the case of an associate editor, or from the Chair of the Publications Committee, in the case of the editor.
ii. Dismissal from the position. 

b. Authors: 
i. A letter from the editor of explanation and education where there appears to be a genuine misunderstanding of principles.
ii. A letter from the editor of reprimand and warning as to future conduct. 
iii. A letter from the editor to the author's institution or funding body.
iv. Publication of a notice detailing the author's failure to disclose the COI.
v. Publication of an editorial detailing the full details of the misconduct.
vi. Refusal to accept future submissions from the author on a sliding scale of one-to-five years.
vii. Formal retraction or withdrawal of the paper from the scientific literature.
viii. Reporting the case to the Office of Research Integrity (ORI). 

c. Reviewers: 
i. A letter from the editor of explanation and education where there appears to be a genuine misunderstanding of principles.
ii. A letter from the editor of reprimand and warning as to future conduct. 
iii. A letter from the editor to the reviewer's institution.
iv. Refusal to allow the individual to review for the journal on a sliding scale of one-to-five years.


This policy was developed in accordance with the guidelines set forth by the Committee on Publication Ethics (COPE) and the International Committee of Medical Journal Editors (ICMJE). 

PLAGIARISM, DUPLICATE SUBMISSION/PUBLICATION POLICY

A. Definitions

a. Plagiarism: Unreferenced use of published and unpublished ideas. It may occur at any stage of planning, research, writing, or publication and applies to print and electronic versions. 

b. Duplicate Submission/Publication: Occurs when two or more papers, without full cross-reference, share the same hypothesis, data, discussion points, or conclusions.


B. Sanctions
Should plagiarism or duplicate submission/publication be identified, the journal editors will apply the following sanctions according to the severity of the infraction. They will apply sanctions to individual authors depending on their type of involvement with the article, as provided at the time of submission on the title page. 


a. A letter of explanation from the journal editors to the authors where there appears to be a genuine misunderstanding of principles. 

b. A letter of reprimand from the journal editors as to future conduct. 

c. A formal letter from the journal editors to the author's institution, employer, or funding body. 

d. Publication of a notice or editorial in journal. 

e. Refusal to accept submissions from the author for a range of one-to-five years. 

f. Formal withdrawal or retraction of paper from the scientific literature. 

g. Journal editors report the case to Office of Research Integrity, which promotes integrity in biomedical and behavioral research supported by the U.S. Public Health Service; monitors institutional investigations of research misconduct; and facilitates the responsible conduct of research through educational, preventive, and regulatory activities.


This policy was developed in accordance with the guidelines set forth by the Committee on Publishing Ethics (COPE) and the International Committee of Medical Journal Editors (ICMJE). 

Image Manipulation Policy
A. Definition*
Image manipulation is the misrepresentation of data by selectively altering portions of an image. The expectations for how images should be ethically handled are: 
a. No specific feature within an image may be enhanced, obscured, moved, removed or introduced.
b. The grouping of images from different parts of the same gel, or from different gels, fields or exposures must be made explicit by the arrangement of the figur
e (eg, using dividing lines) and in the text of the figure legend. c. Adjustments of brightness, contrast or color balance are acceptable if they are applied to every pixel in the image and as long as they do not obscure, eliminate or misrepresent any information present in the original, including backgrounds. Non-linear adjustments (eg, changes to gamma settings) must be disclosed in the figure legend.
*Language used with permission from The Journal of Cell Biology.
B. Process
The journals' graphics staff will screen images at random during the submission process and will review images that editors, reviewers or readers suspect have been manipulated. If manipulation is suspected, the staff and editors will initiate an investigation with the authors and possibly their institutions. 
C. Sanctions
Should image manipulation be verified before or after publication of an article, one of the below sanctions will be applied, based on the severity of the infraction. The journal editor-in-chief and board of editors will determine, on a case-by-case basis, the severity of the infraction and corresponding sanction. Sanctions will be applied to individual authors depending on their type of involvement with the article, as provided at the time of submission on the title page.
a. A letter of explanation from the journal editors to the authors where there appears to be a genuine misunderstanding of principles. b. A letter of reprimand from the journal editors as to future conduct.
c. A formal letter from the journal editors to the author's institution or employer.
d. Rejection or withdrawal of manuscript acceptance.
e. Publication of a correction or editorial.
f. Retraction of the published article.
g. Refusal to accept submissions from the author for a range of one-to-five years. For particularly egregious cases or series of cases, a life-time ban may be considered.
The AGA reserves the right, on a case-by-case basis, to report particularly egregious cases to the relevant funding bodies. 
This policy was developed in accordance with the guidelines set forth by the Committee on Publishing Ethics (COPE). 

Open Access Policies 

Compliance with Funders' Open Access Policies

Gastroenterology's publishing partner, Elsevier, has established agreements and developed policies to allow authors who publish in Elsevier journals to comply with manuscript archiving requirements of various funding bodies (for example, the National Institutes of Health), as specified as conditions of researcher grant awards. For a full list of funding bodies with which Elsevier has agreements, go to  http://www.elsevier.com/about/publishing-guidelines/policies/funding-body-agreements. These agreements and policies enable authors to comply with their funding body's archiving policy without having to violate their publishing agreements with Gastroenterology. The agreements and policies are intended to support the needs of the Journal's authors, editors, and society publishing partners, and to protect the quality and integrity of the peer-review process. 

Author-Sponsored Articles

Gastroenterology offers authors the option to sponsor immediate open access to their articles online at www.gastrojournal.org andwww.sciencedirect.com. Authors can elect to sponsor their article only after receiving notification that their article has been accepted for publication in GASTROENTEROLOGY.The charge for article sponsorship is $3000, which is used to offset publishing costs of typesetting, tagging, and indexing of articles, hosting articles on dedicated servers, supporting sales and marketing costs to ensure global dissemination via www.gastrojournal.org and www.sciencedirect.com, and permanently preserving the published journal article. The fee excludes taxes and other potential author fees such as submission, page fee, and color charges, which are additional. Authors who have had their article accepted and who wish to sponsor their article to make it immediately freely available should complete and submit the article sponsorship order form located at:  http://www.elsevier.com/framework_authors/Sponsoredarticles/sponsoredarticleoption.pdf. You will need your Elsevier Production Article Number to complete the form. You will receive this number via email once your accepted manuscript has been received and processed by the Elsevier production team.

Open Issue Highlights and Archives

The American Gastroenterological Association (AGA) supports free access to GASTROENTEROLOGY on the broadest possible basis while adhering to a publishing model that is economically sustainable over a long horizon. To that end, for each issue of the Journal, several original research articles are identified by the Journal's editor as critical content for readers and thus are made immediately open access. Additionally, all content older than 12 months is free to all online. Also, many special sections of each new issue are immediately free to all online. 

Manuscript Posting

Authors of articles published in GASTROENTEROLOGY may voluntarily post their accepted manuscripts to personal websites or institutional repositories immediately upon acceptance. 

INFORMATION ABOUT ARTICLE TYPES 

Original Articles 
Original Articles are full-length reports of original research.Articles cover topics relevant to clinical, and basic and translational studies in these areas of interest. They may discuss nutrition, immunology, cell biology, molecular biology, morphology, physiology, pathophysiology, epidemiology, imaging, or therapy. Both adult and pediatric problems are included. To be published, the work presented in the manuscript must be original; on occasion, confirmatory studies of timely and important observations will also be acceptable. In addition, other considerations for evaluating the acceptability of a submitted manuscript include its importance, the soundness of the experimental design, the validity of the methods, the appropriateness of the conclusions, and the quality of presentation. 

Original article submissions to Gastroenterology cannot exceed 6,000 words, including the abstract, figure and table legends, and references. No more than a combined total of seven figures and/or tables are permitted. The editor reserves the right to publish excessively long tables as online-only material. Each figure may have up to six panels (labeled A-F). Your manuscript will be returned to you if it does not meet these criteria.

Reviews in Basic and Clinical Gastroenterology and Hepatology 
Each issue of GASTROENTEROLOGY will typically contain a review article by two or more collaborating authors that is solicited by the board of editors (no unsolicited reviews will be considered). Each review article will be divided into two sections, basic and clinical, with one section to be overseen by a basic science editor and the other by a clinical editor. 

Reviews must not exceed a total of 6,000 words, not including references, figure legends or table legends. A maximum of 150 references are permitted. Authors are also required to include a minimum of 4 figures or illustrations and to work with GASTROENTEROLOGY's medical illustrator in developing them. 

Clinical Challenges and Images in GI 
Clinical Challenges and Images in GI presents a striking clinical image that is meant to challenge and inform readers. The "Clinical Challenge and Image in GI" is presented as an unknown with the diagnosis hinging on the correct interpretation and integration of the image and clinical data. The answer is presented on a separate page of the Journal. The section is intended to illustrate and teach important medical points. If you would like to submit an image for publication in the Journal, please follow the instructions below.

Images can be either clinical, pathologic (gross or microscopic), endoscopic, or radiographic. They must be of high quality (300ppi) and illustrate the diagnosis well.
The article must include a title that does not reveal the answer to the challenge. This title will be published should the article be accepted.
The case should be described in one typed double-spaced page or less. Format should be as follows: Short pertinent history, physical exam and laboratory findings, and initial clinical course. The image(s) should then be described with all labeled structures explained in the text.
The answer should discuss the image findings and the diagnosis in no more than one double-spaced typed page. The diagnosis and discussion should make an important medical teaching point and include from one to three pertinent references. Information regarding the specific patient in terms of follow-up and response to therapy should be given as appropriate.
No more than three authors are allowed on each submission. Contributors must provide their names, addresses, phone, and e-mail addresses. Contributors must complete the Author Statement form.
"Clinical Challenges and Images in GI" submissions must be submitted at www.editorialmanager.com/gastro.

Correspondence (Letters to the Editor) 


Correspondence (Letter to the Editor) allows the opportunity to offer novel perspectives and opinions on papers published in GASTROENTEROLOGY. Letters must be submitted for consideration by the end of the month in which the corresponding article was published (eg, a response to an article in the July issue should be submitted by the end of July). At the end of each submission period, all letters received that month will be assessed by the Board of Editors. Letters deemed of interest to the Journal are collated and sent to the authors of the original article for a response; the authors are given 2 weeks to reply. A decision will then be made whether to publish the letter with or without its reply. No more than 3 letters are published for any given manuscript, and they are evaluated in sequence of submission.

Correspondence submissions must not exceed 750 words with no more than 8 references (not included in the word count). Original or unpublished data will not be considered. For the references, use the following format: Jones RS, et al. Gastroenterology 2011; 2: 373 -380 (only the first author is listed, unless manuscripts with joint first authors are cited, and article title is not included).
