Chinese Journal of Minimally Invasive Surgery is jointly hosted by Peking University and Peking University Third Hospital. It is an academic journal reflecting the progress of minimally invasive techniques domestically and internationally. The journal is recognized as a source journal by the China Science and Technology Statistics of the Ministry of Science and Technology, listed in Peking University's ""Chinese Core Journal Overview,"" and sourced in the China Science Citation Database (CSCD). It covers clinical practice experiences and related experimental research in the field of clinical treatment and examination of human injuries, as well as improvements and inventions in medical instruments. The primary readership of the journal consists of senior and intermediate medical personnel engaged in various fields of minimally invasive surgery. The mission of the journal is to disseminate minimally invasive techniques, promote technical and academic exchanges in minimally invasive surgery both domestically and internationally, and advance the development of minimally invasive surgery in China.

1. Sections of the Journal:

Academician and Expert Forum, Clinical Articles, Clinical Research, Experience Exchange in Short Articles, Basic Research, Special Discussions, Special Lectures, Improvements in Interventional Treatment Techniques, New Technologies and Methods, Domestic and International Medical Dynamics, Medical Device Progress, Reviews, Short/Case Reports, Grassroots Hospital Section, Nursing Section, Debate Section, etc. Traditional surgery forms the foundation of minimally invasive surgery; therefore, academic papers related to traditional surgery are also welcomed.

2. Submission Requirements:

2.1 Submissions should be scientific, advanced, practical, and standardized; data should be reliable, information accurate, arguments clear, structure rigorous, writing fluent, figures and tables standardized, and statistical methods correct. For clinical trials involving human subjects, authors should specify compliance with ethical standards for human experimentation and approval from the ethics committee (approval number should be noted in the manuscript), as well as obtaining informed consent from the subjects or their relatives. Articles, reviews, and case reports should generally not exceed 4000 words, with case reports not exceeding 1500 words.

2.2 Title: Titles should be concise, eye-catching, and reflective of the article content. Chinese titles should generally be within 25 Chinese characters.

2.3 Authorship: Author names should be listed in sequence below the title, with the order determined at the time of submission and not altered during editing. Authors should be individuals who (1) participated in topic selection and design or data analysis and interpretation; (2) drafted or revised key theoretical or other major content in the paper; (3) can respond to editorial modifications, defend academically, and ultimately agree to publication. If there are foreign authors, written consent in their native language should be provided, along with their communication address in both their native language and Chinese, using the English names of locations as per official maps. The author's unit specifically refers to the unit where the work was completed (visiting physicians should generally list their visiting unit unless otherwise agreed). Other unit names and postal codes should be footnoted in the bottom left corner of the same page according to author order. Contributors who made significant contributions to the research can be acknowledged. Research supported by various levels of funding must specify the project name, approval number, and be footnoted in the bottom left corner of the same page, along with a copy of the funding approval. The journal will prioritize publication through a fast-track process for funded research projects.

2.4 Abstract: Clinical articles must include a Chinese abstract of approximately 400 words, following the internationally recognized structure, including the paper's objectives, methods, results, and conclusions. Detailed main data and statistical data should be provided in the results section. The English abstract, for international communication purposes, can be more specific (around 600 words) and should include the title, author's name (in Pinyin, with the surname first, capitalized first letters without hyphens), and affiliation. List only the first 3 authors; for more than 3 authors, use ""et al."" If authors are from different institutions, place an asterisk () in the top right corner of the author's name and the first letter of the institution's name. For example: Liu Yuanzhao, Fan Hong, Chu Defa. ""Department of Radiotherapy, Beijing Hospital, Beijing 100730, China.""

2.5 Keywords: Articles should include 2-5 keywords, preferably using terms listed in the latest edition of the Medical Subject Headings (MeSH) from the Index Medicus by the U.S. National Library of Medicine. English keywords should be consistent, with the first letter of each word capitalized and separated by semicolons.

2.6 Hierarchical Numbering: Use Arabic numerals for all hierarchical numbering. Different levels are separated by periods, with no punctuation for the final number (e.g., ""1"", ""2.1"", ""2.1.2""). Intermediate hierarchical arrangements within the text can use ""(1)"", ""①"", etc.

2.7 Medical Terminology: Follow the ""Medical Terminology"" approved by the National Natural Science Terminology Review Committee and published by the Science Press in 1989 and later. For Chinese drug names, refer to the latest edition of the Pharmacopoeia (for legal drugs) or the ""Drug Nomenclature"" edited by the Pharmacopoeia Committee of the Ministry of Health (for non-legal drugs). English drug names should use international non-proprietary names, not brand names.

2.8 Figures and Tables: Figures and tables should be concise, with clear titles and explanations. Explanatory information should be placed in footnotes below the figures or tables, including all non-standard abbreviations used. The journal uses three-line tables (top line, header line, and bottom line), with a dividing line above rows with totals or statistical processing (e.g., P-values). Photographs should have good clarity and contrast. Provide electronic versions of high-resolution photos, with symbols (including arrows) labeled in key areas. Each figure should have a number, title, and description below, corresponding to the text. If using portraits, written consent should be obtained or identities obscured. Pathology photos should include staining methods and magnification. Proper attribution is required for figures and tables from other sources. Copies of figures and tables are not accepted. Generally, no more than 6 figures should be included. Tables should follow a subject-predicate structure, with the study subject as the subject on the left and statistical indicators as predicates on the right. Articles comparing advantages and disadvantages should undergo statistical processing, with specific test values provided before probability values, such as x, F, q values, etc.

2.9 Units of Measurement: Specific usage should refer to ""The Application of Legal Measurement Units in Medicine (3rd Edition)"" edited by the Chinese Medical Association Journal (Beijing: People's Military Medical Press, 2001). Note that unit names and symbols should not mix letters and Chinese characters. For example, instead of ""mg·kg·day,"" it should be written as ""mg·kg·d."" The use of a slash to indicate division in a unit symbol should not exceed one. When encountering this situation, negative exponent notation should be used, such as ""mg·kg."" Slashes and negative exponents should not be mixed in the same unit symbol, for example, avoid using ""s/kg'·min."" Mean and standard deviation values represented as percentages should have the two numbers before and after the ± sign enclosed in parentheses, followed by ""%,"" like (50.2±0.6)%. Percentages should be enclosed in percent symbols, e.g., 5%-95%. Area and volume should be expressed as length x width x height, written as 3cm x 5cm or 3cm x 3cm x 5cm. When indicating a numerical range, use 5,000-10,000 instead of 5-10,000. If necessary, list legal measurement units first in the text, followed by old units in parentheses, e.g., 8.9 mmol/L (160 mg/dL). Blood pressure should be measured in millimeters of mercury (mm Hg).

2.10 Statistics: Select appropriate statistical methods based on the characteristics of the data for quantitative and qualitative data analysis. Symbols should be written according to the relevant provisions of the national standard GB3358-82 ""Terminology and Symbols in Statistics."" Common symbols include: arithmetic mean (denoted by the lowercase English letter ""m""), median (denoted by ""M""), standard deviation (denoted by lowercase English letter ""s""), chi-square test (denoted by the lowercase Greek letter ""χ""), correlation coefficient (denoted by lowercase English letter ""r""), sample size (denoted by ""n""), degrees of freedom (denoted by lowercase Greek letter), probability (denoted by uppercase English letter ""P""), etc. Specific test values should be provided before the P-value. All symbols should be in italics.

2.11 Comparative studies should ensure comparability of inter-group clinical data before making comparisons. Statistical processing should be conducted on all factors (clinical data) that may affect the results before treatment, and comparisons should only be made when there is no significant difference. The factors compared and the statistical methods used should be clearly stated in the paper, along with specific result listings.

2.12 Abbreviations: Abbreviations should generally not be used in titles, and should be minimized in the text. If necessary, the full term should be stated first at its initial occurrence, followed by the Chinese abbreviation or English full term in parentheses, with the two separated by """". If the abbreviation is well-known, the English full term may not need to be provided. Abbreviations should not be split across lines.

2.13 References: To enhance the scientific nature of the article, appropriate references should be cited in all types of articles, with Arabic numerals in square brackets indicating their order of appearance in the text. Unpublished observational data and personal communications are generally not used as references. If possible, references should not be cited more than twice. Authors of references should be listed in full for 1-3 authors, and for more than 3 authors, list the first 3 followed by "", et al."" or similar text. Abbreviate foreign journal names according to the Index Medicus format edited by the U.S. National Library of Medicine; use the full name for Chinese journals, and include the page range for each reference. References must be accurately cross-checked with the original text, with over 50% of references from the past 5 years. The reference format should follow the example below:
