General information

Hepatobiliary & Pancreatic Diseases International is a journal published bimonthly in the English language by the First Affiliated Hospital， Zhejiang University School of Medicine， Hangzhou， China. We welcome original research articles， review articles， editorials， and others from any part of the world. Manuscripts are reviewed by members of the international editorial board and our expert peer reviewers， then either accepted for publication or rejected by the chief editor. Manuscripts should be submitted via https：// mc03.manuscriptcentral.com/hbpdint.

Most of submissions accepted for publication may undergo revisions recommended by the reviewers， editors or statistical advisers. A decision takes from two weeks to three months， the longer period being due to the multiple reviews needed for articles likely to be accepted. Publication varies from two to six months after final acceptance. Proofs of edited articles and illustrations are sent to the corresponding author for correction and reply to any queries from editors. A sample copy of the journal containing the articles will be forwarded to the corresponding author within a few days of publication.

Online submissions

Original research articles including randomized trials，intervention studies， studies of screening and diagnostic tests， cohort studies， cost-effectiveness analyses and case control studies should be prepared in accordance with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals （www.icmje.org）. Those of randomized controlled trials （RCTs） should follow the CONSORT-statement （www.consort-statement.org）. The reporting of other articles should follow the guidelines set by the different initiatives or groups listed in the appendix. The article should be submitted with two separate files， one with detailed information about authors and the title， short running title， source of the work， in addition to the names，address， telephone and fax number or email address for the corresponding author. Another file should show only the title， running title， abstract， main text， tables， figures of the submitted article as well as a list of references， which will be sent to reviewers.

The authors' names （normally no more than six） and their initials should be in the same form as in their other publications with one major qualification such as MD or PhD， their current appointment and a full postal address. One author should be named for editorial correspondence.

Each submission must be accompanied by a letter of copyright transfer signed by all the authors （see the detailed description in the last section） and other relevant documents including informed consent obtained from research subjects and research approval from the supervising or institutional ethics bodies. Author（s） of each submission should clarify the functions in or contributions to their research and declare， if any， competing interest. A choice of one of the following statements will be requested when a decision has been made to accept the paper：

1. The author or one or more of the authors have received or will receive benefits for personal or professional use from a commercial party related directly or indirectly to the subject of this article.

2. No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article.

3. The author or authors do not choose to declare any conflict of interest related directly or indirectly to the subject of this article.

The statements selected by the author or authors will be published with the article. The signature of each author will be required. No article will be published until the completed form has been received at the Hepatobiliary & Pancreatic Diseases International office.

Manuscripts should be prepared with generous margins， and double spacing is essential throughout the text，the references and the captions. Tables， figures， captions and list of references should appear properly in the text. The style should be simple and direct， free from ambiguity and jargon， and with minimal use of abbreviations.

The title of the paper should be chosen with care： a short one has more impact and may be expanded by a subtitle.

Structured abstract of original articles should include four sections as Background， Methods， Results and Conclusions and have no more than 300 words summarizingthe most important points in the article， incorporating key words suitable for electronic retrieval systems. Background：This section should provide a precise statement of the primary focus of the study and the context in which it was carried out. Methods： This section describes how the study was performed， including details of clinical and/or technical procedures. Results： This section describes the salient results of the study. Conclusions： This section covers conclusions and their clinical application or others， while equal emphasis should be given to positive and negative findings of equal scientific merit.

The main text should be divided under headings. For many research papers the best sequence is Introduction，Methods （Materials or Patients）， Results， and Discussion. The text should comment on， but should not repeat， the details given in tables， figures or captions. Any acknowledgements should be made at the end of the main text.

Introduction： This should explain the problem which is to be addressed， with a definition of the hypothesis to be examined if appropriate， out-lining， briefly， its relevance to the appropriate literature.

Methods （Materials or Patients）： The subjects of the study and the methods employed in the investigation must be clearly described. For example， the reasons for examining the particular group of patients should be made clear，and reasons for exclusion of individuals from the study must be stated. Any group used as controls must be defined accurately.

Ethical approval of studies and informed consent are required. For all manuscripts reporting data from studies involving human participants or animals， formal review and approval， or formal review and waiver， by an appropriate institutional review board or ethics committee is required and should be described in the Methods section. For those investigators who do not have formal ethics review committees， the principles outlined in the Declaration of Helsinki should be followed. For investigations of humans， state in the Methods section the manner in which informed consent was obtained from the study participants （i.e.， oral or written）. Editors may request that authors provide documentation of the formal review and recommendation from the institutional review board or ethics committee responsible for oversight of the study.

Results： These must be clearly expressed in simple language. Tables or similar diagrams can be used but must not duplicate material already described in the text.

Discussion： This section must be succinct， pointing out the relevance of the work described in the article and its contribution to current knowledge. The results must be interpreted clearly， and both strength and weakness expressed. Discussion of pertinent references must be concise and short.

Each of the tables should have a short descriptive heading.

The references in the text should include only those that are important and have been studied fully by the authors. The authors are responsible for the accuracy and completeness of the cited references and for correct citation of the text. When listing references the names of journals should be abbreviated according to Index Medicus （List all authors and/or editors up to 6； if more than 6， list the first 6 and et al）. All references will be checked deliberately by the authors； PMID roots in the abstract serial number indexed by PubMed （http：//www.ncbi.nlm.nih. gov/sites/entrez？db=PubMed） are requested. The references cited should be represented in the text by superscript numbers in the order of their appearance. The list of references at the end of the text should be in this numerical order with details and punctuation as follows：
