2. Writing Requirements

2.1 Title: The title should appropriately and concisely reflect the theme of the article, generally not exceeding 25 Chinese characters. Avoid using foreign abbreviations and vague terms like ""study of..."" or ""observation of..."". The English title should convey the same meaning as the Chinese title.

2.2 Authors: Authors should be involved in the research work, able to address the issues raised in the article, and be responsible for the content. Articles with collective authorship must clearly identify the responsible author and provide their email address. For foreign or Hong Kong, Macao, and Taiwan authors, written consent from the individual should be attached. The number and order of authors' names are determined by the authors themselves and should not be changed during the editing process. Any changes in authorship require written consent from all authors. Author affiliations should include the full name of the institution, department, city name, postal code, and provide the name, address, phone number, and email of the corresponding (responsible) author. Authors from different institutions should be marked with superscript numbers (1, 2...) next to their names, and corresponding numbers (1, 2...) should be indicated before their institutional affiliations. In articles with English abstracts, all English information should correspond to the Chinese author information.

2.3 Abstract: The Chinese abstract should be no less than 500 words, while the English abstract should be more detailed, with a minimum of 350 words. Articles, technical methods, and research briefs should include Chinese and English abstracts written in the third person using a structured format, including sections for objectives, methods, results (main data should be included), and conclusions, each with a corresponding title. For difficult/rare case analyses, both Chinese and English abstracts are required, with the English abstract following the Chinese abstract. Reviews and case reports only need an English abstract, placed after the main text. Abstracts for these sections should be in a non-structured format (not divided into objectives, methods, results, and conclusions).

2.4 Keywords: Each article should have 3-5 keywords, preferably selected from the latest edition of the Medical Subject Headings (MeSH) by the U.S. National Library of Medicine. Keywords should be separated by semicolons.

2.5 Study Design: Clearly state whether the study design is prospective, retrospective, or cross-sectional for survey designs; specify the specific design type for experimental designs (e.g., self-paired design, group design, crossover design, etc.); for new drug clinical trial designs, indicate the phase of the trial, blinding measures used, inclusion and exclusion criteria for subjects, and describe the methods of quality control.

2.6 Statistical Analysis: Provide the specific names of the statistical analysis methods used (e.g., t-test for grouped design data, analysis of variance for two-factor design data) along with specific values of statistical measures and P-values (e.g., t=3.45, P<0.01); when inferring population parameters, also provide a 95% confidence interval. For quantitative data, use the format ""mean ± standard deviation"" and select appropriate statistical analysis methods based on the design type, data conditions, and analysis objectives. Avoid using linear regression equations for data showing significant curve trends on scatter plots. Correlation analysis should not be used to indicate the degree of agreement between two testing methods. For multi-factor, multi-indicator data, after single-factor analysis, utilize multi-factor statistical analysis methods as much as possible to provide a reasonable explanation for interactions between factors and intrinsic relationships between multiple indicators. When using relative numbers, the denominator should not be less than 30. Differentiate between the meanings of percentages and percentage points. Write statistical symbols in italics according to the relevant provisions of GB 3358-82 ""Terminology and Symbols in Statistics"".

2.7 Medical Terminology: Refer to the ""Medical Terminology"" approved and published by the National Committee for Science and Technology Nomenclature, or consult the official website of the National Committee for Science and Technology Nomenclature for unpublished terms, using the ""English-Chinese Medical Vocabulary"" compiled by the People's Health Publishing House as a reference. Drug names should adhere to the latest version of the ""Pharmacopoeia of the People's Republic of China"" or the ""Chinese Pharmacopoeia"" compiled by the Pharmacopoeia Committee of the Ministry of Health (Beijing: Chemical Industry Press, 1997), avoiding brand names.

2.8 Quantity and Units: Adhere to the GB 3100-3102-93 series of standards and relevant international regulations for the standardized use of quantity and unit names and symbols. Quantity symbols are represented in italic Latin or Greek letters (except pH in regular font), such as m (mass), t (time), λ (wavelength), etc. Unit symbols should be in regular font, such as g (grams), m (meters), etc. When representing numerical values with units in figures and tables, use the standardized form of ""quantity/unit,"" for example, ""t/h"" (time unit ""hour""), ""p/kPa"" (pressure unit ""kilopascal""), etc.

2.9 Numerals: Follow the provisions of GB/T 15835-2011 ""Usage of Numerals in Publications.""

2.10 Figures and Tables: Number figures and tables consecutively based on their appearance in the text. Each figure (table) should have a concise title in both Chinese and English. Explanatory information should be written in English and placed below the figure (table). Arrange and label table columns and rows logically in English, ensuring clear expression of data meanings; maintain the same number of decimal places for data of the same indicator, generally one more than the accuracy of measurement. Figures should not be oversized, with a maximum width of half-column figures not exceeding 7.5 cm and full-column figures not exceeding 17.0 cm; the aspect ratio of height to width should be around 5:7. Photographs should have good clarity and contrast. Pathology photos should include staining methods and magnification. When using portraits, written consent should be obtained from the individual or identities should be obscured. When citing published figures, provide the source and written permission from the copyright owner.

2.11 Abbreviations: When abbreviations are necessary, provide the full Chinese name at the first occurrence, followed by the Chinese abbreviation or English full name and its abbreviation in parentheses, separated by a comma (if the abbreviation is well-known, the English full name may be omitted).

2.12 Acknowledgments: Brief acknowledgments for collaborators, assistants, guides, and sponsors can be expressed in a concise manner. Acknowledgments should be placed in parentheses after the main text and before the references.

2.13 References: Follow the provisions of GB/T 7714-2015 ""Information and Documentation - Rules for Bibliographic References."" When citing others' published works, such as text, figures, tables, or data, it is necessary to list the references to indicate the source. This journal uses a sequential numbering system to record references. In the main text, references should be marked with square brackets at the upper right corner of the sentence or next to the cited author. References cited in tables or figure captions should also be coded according to the order of appearance in the main text. References in articles should mainly consist of primary literature personally read by the authors, with over 50% of the references from the past 5 years. Internal documents, personal communications, unpublished or forthcoming articles are generally not used as references; abstracts, reviews, and other secondary literature should be avoided if possible. When listing authors in references, all authors (1-3) should be listed; for more than 3 authors, list the first 3 followed by "", et al."" Chinese authors' names written in Pinyin should follow the Western format. In English article titles, capitalize the first word and proper nouns, with the rest in lowercase. The abbreviation of foreign journal names should follow the List of Journals Indexed in Index Medicus compiled by the National Library of Medicine in the United States or can be checked online via PubMed. Authors should carefully verify the cited references to ensure accuracy. Arrange the references in numerical order of citation at the end of the document, as shown below:
