Author Guidelines

Style and format

Manuscript files, such as the paper itself, supplementary files, and cover letter, can be in the following formats: DOC or DOCX. Manuscript text should be double-spaced. Do not format text in multiple columns. Microsoft Word documents should not be locked or protected. Separate data file can be prepared using MS Excel.

For manuscript files, use page numbers and continuous line numbers.

Define abbreviations upon first appearance in the text.



CAS Medicine is a bilingual journal. All articles can be written in either English or Chinese.

American English is preferred if articles are written in English, but no mixture of different English variants (e.g. American English and British English) is allowed.

The manuscript must be presented in an intelligible fashion (good readability, clarity and logical flow considered) and is written in standard English or Chinese. CAS Medicine reserves the right to reject or desk-reject submissions that do not meet these standards.


Letter capitalization

Use sentence case capitalization in all aspects of the manuscript. In sentence case, most major and minor words are lowercase (proper nouns, including name of organizations and name of guidelines, are an exception in that they are always capitalized for the first letter of each word, except for minor words, such as conjunctions and short prepositions). The first letter of the first word should always be uppercase.


Cover letter

All submissions should include a cover letter as a separate file. The cover letter is confidential and will be read only by the editors. A cover letter should contain the following:

  • a brief explanation of what was previously known, the conceptual advancement with the findings and its significance to broad readership
  • any associated accession numbers or DOIs of the corresponding preprint version of the submission if it has been deposited on a preprint server
  • conflict of interest statement
  • a list of names and email addresses of all co-authors of the work who have already seen and approved the manuscript


Manuscript title

The title should capture the conceptual significance for a broad audience. The title should not be more than 50 words and should be able to give readers an overall view of the paper’s significance. Titles should avoid using uncommon jargons, abbreviations and punctuation.


List of Authors

The names of authors must be spelled out rather than in initials. Authors should be listed according to the extent of their contribution, usually with the major contributor listed first. Corresponding author should be identified with an asterisk.

Affiliations should contain the following core information: department, institution, city, state, postal code, and country. For contact, email address of at least one corresponding author must be included.

Please note that all authors must view and approve the final version of the manuscript before submitting.



Every manuscript must include an abstract, preferably not more than 250 words. The purpose of abstract is to provide sufficient information for a reader.



Each manuscript should be accompanied by 3 to 6 keywords. Use semi-colon to separate keywords, e.g. term1; term2; term3.


Section Headings

Section headings should be in boldface. Examples of section headings of different levels are shown in the following:

Primary level               : 1. Heart disease

Secondary level          : 1.3 Risk factors for heart disease

Tertiary level               : 1.3.2 Hypertension

Authors are suggested not introducing further sub-sections of the tertiary level section (e.g. High-salt diet).


Research Ethics

Research ethics information, such as ethics approval identifiers and the name of Institutional Ethics Review Board or Institutional Review Board, should be indicated in the appropriate section of the manuscript, if applicable. Relevant documents and proof in relation to research ethics should be made available to the editors during submission.


Consent forms

Authors should supply sample patient consent form during submission of human research-related papers.



This is an optional section where authors can acknowledge people and/or institutions that has helped with the research and preparation of the manuscript.



Authors should declare all financial and non-financial support that have the potential to be deemed as a source of competing interest in relations to their submitted manuscript in this section. Financial supports are generally in the form of grants, royalties, consulting fees and others. Examples of non-financial support could include the following: externally-supplied equipment/biological sources, writing assistance, administrative support, contributions from non-authors, etc.


Conflict of Interest

During submission, the Conflict of Interest statement should be included in both the cover letter and as part of the back matter of the manuscript. Authors who have nothing to declare are encouraged to add "No conflict of interest was reported by all authors" in this section.


Unit of measurements

Use SI units.


Nomenclature of genus and species

Write in italics (e.g. Escherichia coli). The full genus and species names must be mentioned both in the manuscript title at the first appearance of an organism in an article. The abbreviation (e.g. E. coli) is allowed after first mention.


Nomenclature of genes, mutations, genotypes, and alleles

Write in italics. CAS Medicine highly encourage the use the recommended names found in the gene nomenclature databases, for instance, HUGO Gene Nomenclature Committee.



Authors should include all figures in the manuscript and submit it as a single file. Figures include photographs, scanned images, graphs, charts and schematic diagrams. Figures submitted should avoid unnecessary decorative effects (e.g. 3D graphs), as well as should be minimally processed (e.g. changes in brightness and contrast applied uniformly for the entire figure should be avoided or minimized). All images should also be set against white background.

Label all figures (e.g. axis, structures) and add captions below the figure. These captions should be numbered (e.g. Figure 1Figure 2, etc.) in boldface. Each figure should have a brief title (also known as caption) that describes the entire figure without citing specific panels, followed by a legend, which is either the description of each panel or further description about the single image. Identify each panel with uppercase letters in parenthesis (e.g. (A), (B), (C), etc.)

The preferred file formats for any separately submitted figure(s) are TIFF or JPEG. All figures should be legible in print form and of optimal resolution. Optimal resolutions preferred are 300 dots per inch (dpi) for RBG colored, 600 dpi for grayscale and 1,200 dpi for line art. Although there is no file-size limitation imposed, authors are highly encouraged to compress their figures to an ideal size without unduly affecting the legibility and resolution of figures.

The Editor-in-Chief and Publisher reserve the right to request from author(s) the high-resolution files and unprocessed data and metadata files, should the need arise at any point after manuscript submission for reasons such as production, evaluation or other purposes. The file name should allow for ease in identifying the associated manuscript submitted.


Tables, lists and equations

Tables created using Microsoft Word table function are preferred. The tables should include a title at the top. Titles and footnotes/legends should be concise. The titles should be numbered (e.g. Table 1Table 2, etc.)  These must be submitted in the manuscript.

Likewise, lists and equations should be properly aligned and its meaning clear to readers. For listing items within the main body of the manuscript, use Roman numbers in parenthesis (e.g. (i), (ii), (iii), (iv), etc.).


Supplementary files

This section is optional and contains all materials and figures that have been excluded from the entire manuscript. These materials, figures or additional information are relevant to the manuscript but remain non-essential to readers’ understanding of the manuscript’s main content. All supplementary information should be submitted as a separate file during submission. Please ensure the names of such files contain “Suppl. file.” Supplementary figures and tables should be submitted in a single, separate supplementary file, and must be numbered, for example, Figure S1 and Table S1. Citations of these items must be appropriately referenced in the manuscript, for instance, “Additional information can be found in Table S1.” Note the additional letter S helps distinguish normal from supplementary items.

Videos can be uploaded as part of the supplementary file, with a constituent maximum size of 500 MB.


In-text citations

Reference citations in the text should be numbered consecutively in superscript square brackets. Some examples:

  1. Negotiation research spans many disciplines[3,4].
  2. This result was later contradicted by Becker and Seligman[5].
  3. This effect has been widely studied[1–3,7].

Personal communications and unpublished works can only be used in the main text of the submission and are not to be placed in the Reference section. Authors are advised to limit such usage to the minimum. These should also be easily identifiable by stating the authors and year of such unpublished works or personal communications, and the word ‘Unpublished’ in parenthesis.

E.g. (Smith J, 2000, Unpublished)



This section is compulsory and should be placed at the end of all manuscripts. Do not use footnotes or endnotes as a substitute for a reference list. The list of references should only include works that are cited in the text and that have been published or accepted for publication. Personal communications and unpublished works should be excluded from this section.

For the reference list, all authors must be stated. Authors being referenced are listed with their surname or last name followed by their initials. All references should be numbered (e.g. 1, 2, 3, etc.) and sequenced according to the order they appear as the in-text citations. References (especially journal article’s) should follow the general pattern: author(s), followed by year of publication, title of publication, abbreviated journal name in italics, volume number, issue number in parenthesis and lastly, page range. If the referred article has more than three authors, list only the first three authors and abbreviate the remaining authors as the italicized ‘et al.’ (meaning "and others"). Include DOI, if available, after the page range. Examples of references for different types of publications are as follows:
