2. Specific Requirements for Original Research Articles

2.1. Requirements for Scientific Papers

• Originality: Submitted manuscripts must not have been previously published in any domestic or international journal.

• Page Limit: The total length of original research articles must not exceed 15 pages, and review articles must not exceed 25 pages.

Presentation and Layout

• Illustrations: The total number of illustrations and results (including tables, figures, charts, and images) must not exceed 5 and/or must not occupy more than 1/4 of the total pages of the manuscript. Captions must be numbered sequentially by type (e.g., Figure 1, Figure 2, Table 1, Table 2). Table titles must be placed above and centered. Figure and chart titles must be placed below and centered.

• Manuscript Structure:

  • Article Title: Must be concise, reflect the core content of the paper, and begin with a noun.

  • Author Information: Full names of all authors, institutional affiliations, and locations where the work was conducted (do not include academic titles, degrees, or positions). The primary author is listed first. The corresponding author (e.g., supervisor) is listed last, with their full contact address, email, and phone number clearly specified. All contributing authors must be fully listed.

  • Vietnamese Abstract: No more than 300 words, written in prose format, covering the objectives, subjects, methods, main results, and conclusions. Provide a maximum of 5 keywords/phrases.

  • English Title and Abstract: Placed at the very end of the manuscript (after the References). It must be an accurate and complete translation of the Vietnamese title, abstract, and keywords.

  • Full Text Structure:

    • Introduction (including research objectives): State the rationale or hypothesis of the study and the specific objectives (avoid duplicating the article title).

    • Materials and Methods: Write concisely but with sufficient detail, including: study subjects, study design, research tools, data collection methods, data analysis methods, and research ethics.

    • Results: Presented through tables, charts, figures, or text.

    • Discussion: Authors must compare their findings with previous studies and interpret the results. The discussion can be combined with the results; if so, the heading should be labeled "Results and Discussion".

    • Conclusion: Short and precise, directly answering the stated research objectives.

    • Recommendations: If applicable.

    • Acknowledgments: Express gratitude to funding bodies, institutions, or collaborators who contributed to the study.

Unit System

Authors must use the Standard International (SI) unit system throughout the article:

• Mass – kg

• Length – m

• Volume – l

• Time – s

• Amount of substance – mol

• Electric current – A

• Luminous intensity – Cd

• Temperature – °C

Note on spacing: Always insert a space between the number and the unit (e.g., 2 kg, 2 mol). Exceptionally, temperature (°C) and percentage (%) units must be written without spaces (e.g., 27°C, 30%).

Units are written in lowercase (m, s, kg). Units named after scientists must capitalize the first letter (N - Newton, Pa - Pascal, V - Volt). The "k" in kilo must always be lowercase (kg, km, kW), whereas capital "K" stands for Kelvin.

Decimal Separators:

• For articles written in English, use a period (e.g., 10.5 mg).

• For articles written in Vietnamese, use a comma (e.g., 10,5 mg).

2.2. Requirements for Review Articles, Short Communications, and Translations

• Review Articles: Must include comprehensive references and cited data sources. The author's academic title, degree, specialization, and institutional affiliation must be specified at the bottom of the first page. The total number of references must not exceed 100.

• Short Communications and Translations: Must clearly state the origin of the data sources used. For translated articles, a full photocopy of the original foreign language text must be attached and submitted alongside the translation.

3. Reference Guidelines

References must be cited according to the Vancouver system. Authors are highly encouraged to use reference management software (such as Zotero, Mendeley, etc.). At least 50% of the total cited references must have been published within the last 5 years from the date of manuscript submission.

3.1. Formatting the Reference List

Key rules for the Vancouver system:

• Order of Appearance: The reference list is not sorted alphabetically (A-Z). References are numbered sequentially based on their first appearance in the text. The first cited source is [1], the second is [2], and so on. If reference [1] is cited again later in the text, it retains the number 1.

• The "6 Authors" Rule: If a publication has 1 to 6 authors, list all authors. If it has more than 6 authors, list the first 6 authors followed by a comma and "et al.".

• Journal Title Abbreviations: Journal names must be abbreviated according to the US National Library of Medicine (NLM) standard. For example, "New England Journal of Medicine" must be abbreviated as "N Engl J Med". Do not place a period after the abbreviated words (unless it is the final word of the title).

Reference Examples:

• Journal Article (Fewer than 6 authors):

  Halpern SD, Ubel PA, Caplan AL. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347(4):284-7.

• Journal Article (More than 6 authors - Use et al.):

3.2. In-text Citations

Within the body text (Introduction, Discussion, etc.), use numbers in [square brackets] to indicate the cited source.

• Example: Type 2 diabetes is a leading cause of blindness [1]. Recent studies by Rose et al. [2] also support this finding.

• If citing multiple sources simultaneously, format as [1, 2], or [1-3] for consecutive numbers.
