    2.5 Introduction 

    Introduction of a manuscript located in the front of the paper is an important part although without a title for it. The introduction includes four parts of contents: (1)The problem or controversy that led you to undertake the study. (2) Background of this study, including a concise review with the most relevant literature cited. (3) Objective, hypothesis and innovation point of this study, which should match that of the Abstract. (4) Method, including the design and main method of the study. The introduction usually consists of 500 Chinese characters.


    2.6 Material and methods

    The material and methods part reflecting whether or not the manuscript is scientific and advanced, mainly includes four parts of contents: (1)Study subject and grouping, including inclusive and exclusive criteria, ethic approve or consent from patients, the grouping method, number in each group, and timing. Nominating the groups should reflect the features directly, such as “**minimal invasive group”, “** traditional group”, whereas the “observation group” and “control group” should be avoided for easy reading. (2) Treatment, including operation method, drug usage, rehabilitation method, and experimental interference, should be described concisely and accurately, while the main modified method should be explained clearly and the innovation points should be revealed in detail. (3) The observation indicator should be comprehensive. The objective quantitative indicators, such as test value, radiological measures, are preferred. Non-quantitative clinical symptoms, physical signsand function should be digitalized using the internationally recognized scales instead of self-established by the author for the comparison with other materials. (4) Statistical evaluation includes the statistical software used, expression of the consequences in data, statistical methods for different materials and test level.

    The part of material and methods accounts for 30% of the wholebody, are about 1500-1600 Chinese characters in the original article.


    2.7 Results

    The results are core of themanuscript for expressionof your innovations. The original consequences and data analyzed statistically are expressed here in a form of combination of text, tables and figures. The text describes the objective phenomena and the result trends,while the table provides specific data and statistic values, the figures present specific phenomenon directly. The data listed in the tables should not be repeated in the main text. The text of result should be written following the order of the Methods or in alogical sequence. The tables and figures must be self-evident with logical integrity by a title, notes and legends, which should be marked at the matching place at the text.

    The result part accounts for 30% of the whole article, about 1500-1600 Chinese characters in the original article.


    2.8 Discussion

    The discussion part focuses on the demonstration, reasoning, and evaluation of the mechanism and significance of the results. The core results are mentioned without repeating the specific data, which should be compared and contrasted with others in the most relevant world literature, particularly the recent literature. A complete literature review is unnecessary. At the end of the Discussion, the limitations of your study should be reviewed. 

    The part of discussion accounts for 30% of the whole article, about 1500-1600 Chinese characters.


    2.9 Technical note

Video files are recommended as well and patent declaring is needed for those with intellectual property right before submission. (3)Shot-term follow-up results and one or two typical cases reports with relevant pictures are required.(4) Discussion focuses on the comparison of the innovation point with literatures,advantages and disadvantages of the new technique.


    3. Writing requirement

    3.1 Script

    The article should have innovative, scientific,oriented and practical features, with correct data, clear proposition, rigorous structure and refined text. Various laws and regulations, such as The General Language Law of the People's Republic of China(2010-10-31), Notice on Further Regulating the Use of Publications in Writing released by General Administration of Press and Publicationon(GAPP) on December 24, 2010,Regulations for the  Use of Chinese Characters in Publications released by GAPP and State Language Work Committee in 1992, Simplified Summary Table released by State Language Work Committee in October 1986, and Modern Chinese Characters Table released by State Language Work Committee and GAPP in March 1988 should be strictly carried out. For foreign languages, standard Chinese translation is required and for the name of foreigners, only last name is needed. Mixed usage of Chinese/English languages should be avoided.


    3.2 Terminology

    The usage of terminology is subject toMedical Terminology released by National Committee on Scientific and Technical Nouns, and for those not published before, English/Chinese Medical terms published by the People’s Medical Publishing House is the final standard. The unit of measurement is accordant with legal unit of measurement and their derived unit/unit symbol stipulated by the State Council. Application of Legal Unit of Measurement on Medicine published by Chinese Medical Association, and the latest version of Pharmacopeia of the People’s Republic of China could be references for use of measurement unit or drug names.

     Abbreviation should be avoided using, however, the well-accepted abbreviation could be used directly without annotation, such as CT, MRI, DNA, RNA, et al.

    3.3 Serial number of all levels of titles

      Arabic consecutive numbering is adopted for all levels of titles, with polka dots separating numbers of different levels, without punctuate after the last number. When more than 4 levels, (1), (2), (3) are used for further divide.


    3.4 Numbers and symbols

    Three position segmentation is used for number spelling (ie, 2, 431), but not for spelling of year, page, military designation, instrument type, standard number. The average number should be accompanied with standard deviation (s) . The decrease of number can be expressed only with fraction or %, such as “decreased by 1/4 or 25%”. The range of number should be expressed as: five to ten:5~10,  5×109 to 9×109: (5~9)109, not 5~9×109; 63% to 70% : 63%~70%, not 63~70%. For expression of area of volume multiplied by length, the unit of length can not be omit, such as 20cm×25cm×28cm, not 20×25×28cm3.


    3.5 Statistical method

    According to national standard GB3358.1-2009 Nouns and symbols in statistics, the statistical management must be listed for a single item within clinical materials, and marked with name and version of statistical software, detecting method. The conclusive index should be indicated with specific test value, such as t value, X2 value,Q value, et al., and followed with P value. When P<0.05 (P<0.01), the correct statement is statistical significance of the difference between groups, not significant difference (or quite significant difference) between groups. The specific name of the statistical method should be stated, such ast test of group design data, two factor factorial design data variance analysis, q test multiple comparison between multiple means. When P value needs to be described concretely (for example,t=2.657, x2=3.672,F=5.783), three expressions (P>0.05, P<0.05, P<0.01) are enough, with no use for more subdivisions, such as P<0.001 or P<0.0001. When involving general parameters (general means, general rates, et al), 95% confidential area should be given at the same time the significant test results is given.
