Please try to use terms listed in the latest edition of "Medical Subject Headings (MeSH)" edited by the National Library of Medicine. If necessary, keywords not included in MeSH can also be used.

Medical terms should adhere to the "Medical Terminology" published by the National Natural Science Terminology Review Committee (published by Science Press). Terms without commonly used translations should be annotated or explained when first mentioned in the text. Drug names (including Chinese medicine) should follow the "Pharmacopoeia of the People's Republic of China" (No. 78, 2020), and Chinese drug names should use chemical names instead of brand names.

7. Units of Measurement

Adhere to the State Council's "Legal Measurement Units of the People's Republic of China," correctly using and writing the names and symbols of quantities and units in the manuscript. Quantity symbols should be in italic Latin or Greek letters (except pH in regular font). In figures and tables in the manuscript, standardized forms like "quantity/unit" should be used to represent quantities and units, e.g., "t/h" (time unit "hour"), "p/kPa" (pressure unit "kPa"). The unit following each numerical value with a length unit should not be omitted, e.g., 40mm x 20mm x 30mm should not be written as 40x20x30mm or 40x20x30mm3.

8. Numbers

Arabic numerals should be used where appropriate, such as for centuries, decades, years, months, days, times, counts, and measurements. Representations of numerical ranges should use the format 5-10 for 5 to 10; 5,000-10,000 for 5,000 to 10,000; 60%-70% for 60% to 70%, and not written as 60-70%. Mean and standard deviation represented as percentages should be written as (50.2+0.6)%, not as 50.2 + 0.6% or 50.2%+ 0.6%. Fractions should use a slash instead of a colon, except in mathematical formulas.

9. Figures and Tables

Figures and tables should be sequentially numbered according to their appearance in the text, with each figure or table labeled in the text. Each figure or table should have a clear and self-explanatory title. The journal uses three-line tables without vertical lines. Illustrations should be professionally drawn or photographed; letters, numbers, and symbols in the figures should be clear and distinguishable even after reduction. Each figure should have a label on the back indicating the figure number, author's name, and the top and bottom orientation of the figure. Images should not be folded. Microphotographs should indicate the magnification factor and staining method. Symbols, arrows, or letters in photos should contrast sharply with the background. If using portraits, written consent from the individual should be obtained, or the part identifying the person should be obscured. Proper attribution should be provided for figures and tables sourced from other publications. Whenever possible, textual descriptions should be used instead of figures and tables.

10. Statistical Symbols

Statistical symbols should be written according to the relevant provisions of "Nomenclature and Symbols in Statistics" (2009 edition) [GB/T 3358.1-2009, GB/T 3358.2-2009, GB/T 3358.3-2009].

Unpublished observational data and personal communications are generally not included in the references. Secondary sources should not be cited; instead, cite the original source. List all authors for references, with 1-3 authors listed in full and more than 3 authors listed as the first 3 followed by ", et al."
