Guide for Authors

Asian Pacific Journal of Tropical Medicine is sponsored by the Hainan Medical University and is aimed to set up an academic communication platform for Chinese and the rest of the world on tropical medicine and other related fields. We hope that the publication of our new journal will bring us a great opportunity for international academic communication and research. Furthermore, we wish to enhance the competency of preventing and curing tropical and related diseases in China and Asia-Pacific region. The journal invites concise reports of original research in all areas of tropical medicine and related fields, both experimental and clinical, including: modern, traditional and epidemiological studies from any part of the world. Review articles and mini-reviews (no more than 4 printed pages), based primarily on the author(s) own research on internationally important topics are welcome. Short communications and letters to the editor are also welcome. Authors are requested to submit a covering letter indicating that their manuscript represents original unpublished material and will not be published elsewhere (if accepted). This restriction does not apply to results published as abstracts of communications, letters to the editor or as preliminary reports. By submitting a manuscript, the authors warrant that they have obtained permission to use any copyrighted or previously published material. Authors must declare any financial support or relationships that may pose any possible conflict of interest.

Title page The title page should contain, on separate lines, the title of the manuscript, a running title of no more than 40 letters, the name(s) and affiliation(s) of the author(s), and the mailing address, telephone and fax numbers, and e-mail address of the corresponding author. The title must be informative, specific, and concise. Serialization of articles into parts is not permitted. Such articles may be submitted independently with self-sufficient titles.

Keywords and abstract Please provide 3-10 keywords or phrases for indexing purposes, using terms from the latest US National Library of Medicine. If MeSH terms are not available, other appropriate terms may be used. Full-length manuscript submission should include an abstract of up to 250 words in a structured form, consisting of: Objective, Methods, Results, and Conclusion.

Main text The text should include the following sections: Introduction summarizes the rationale, provides a concise research background (not an exhaustive review) and states in one sentence the objective of the study. Please do not include any results or the conclusions of the study. Materials and Methods should provide technical information about the study. There is no need to describe methodological details that have been published previously. Specifications (including the manufacturer, city, and the country) should be given for the main drugs, chemicals, and instruments. Indicate the statistical methods used and identify statistical significance using superscripts (* and **) following the data (*P < 0.05, **P < 0.01). Results are the findings, using SI units. In a sample, the number of effective digits is determined by the variation within the sample, that is, one-third of the standard deviation. Digits may be separated into groups of three by a small space. Discussion deals with the interpretation of the results and their comparison with those of other studies. There is no need to: repeat the results, review literature, textbook knowledge or cite references that do not have a close relationship with the present result. End with a brief conclusion linking back to the aim of the study.

Abbreviations The use of abbreviations, except for units of measure, is discouraged. At the first appearance in the abstract and the text, abbreviations should be preceded by words for which they stand.

Tables Tables must be concise and cited consecutively using Arabic numerals in the text (Table 1, Table 2...etc.). Each table should be typed on a separate sheet. The title of the table should clearly indicate the nature of the contents and sufficient detail should be included in the footnote to facilitate interpretation without reference to the text. Use horizontal rules only.

Figures Figures (photographs, drawings, diagrams and charts) should be clear, easily legible and cited consecutively using Arabic numerals in the text(Figure 1, Figure 2...etc.). Please supply figures 1.5 to 2 times the size at which they will be finally reproduced. For line work, submit black-ink drawings of professional quality. Micrographs or other glossy photographs must be of the highest quality. Use standard symbols: ○, ●, ×, □, ■, △, ▲. Freehand or typewritten lettering is unacceptable. If a figure comprises more than one glossy photograph, these should be marked A, B, C...etc. Figure legends should be marked clearly with their correspond letters. Legends should contain sufficient detail to permit figure interpretation without reference to the text. Scale markers should be indicated in the photographs. Color plates are also welcome. The choice of cover art illustration will be made by the Editor.

References The Journal advocates the citation of new papers; old references are better replaced with updated ones. The authors are responsible for the correctness of references. References are numbered consecutively in the order in which they appear in the text. Citations should be labeled with square bracket and should appear in front of the period or comma at the end of the sentence/clause. All references should be cited. Unpublished data, personal communications, abstracts at meetings and manuscripts submitted for publication are not acceptable as references. Information from such sources may be cited in the text with the sources given in parentheses. References should be listed in a numerical order in the Reference section according to Vancouver Style. Journal titles should be abbreviated according to the list of Journals Indexed in Index Medicus or MEDLINE (
