(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.
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.
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
The technicalnote is newly added in this journal, involving the innovation or reform of the technical method, instruments and material. The main text of this kind of article includes: (1) Preface includes background,current problems, purpose and innovation point of the new technique. (2)The new technique and methods are introduced in detail here, attached with sketches or pictures.

(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
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.

3.5 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.

The transverse column is for groups and the longitudinal column is for indexes, and a transverse line must be added when statistical content is added in the table ( such as t value, P value, et al.). Data in the table have up to two digits after the decimal places and the statistical value is up to three digits after the decimal places. The table annotation is below the table body, including explanation of symbols, abbreviations in the table. The table making function in WORD is commended for the making of table, and all tables should be put at the bottom of the article and separated with front content (generally references) with page break.
Figures should be listed continuously with schedule numbers as the same order they appear in the main text. All figures are listed with the listing number Figure 1, Figure 2, Figure 3, et al. Sub-figures are listed with the listing number a, b, c et al. Figures should be put at the bottom of the article and separated with front content (tables) with page break. The scaling in sub-figures should be consistent and one joint should in a limb figure. Below each figure of figure series are figure number, descriptive title, descriptive innovation, including age, sex of patients, preoperative diagnosis, name of the surgery, timing of photograph. The dye method and magnification times should be given clear indication in symptom description and pathology pictures. If the figure is cited from other journals, the original name of journal should be indicated and the authorization should be acquired from the owner of copyright.
Except for the figures in the main Word text, separated clear figure files should be uploaded to the system ofthis journal, with clearclarity and contrast, JPG format, and at least 300 dpi resolution ratios.
Video or animation files are recommended for technical articles to improve the readability. The content of video or animation should include general information of patients, symptom and body signs, results from laboratory, preoperative diagnosis, body position of surgery, anesthesia and incision, operation instrument and operation steps, pre- and postoperative radiological materials, matters needing attention and traps in the operation.

The authors can make 10~20 slides using Powerpoint 7.0 ( or plus-), and a 5min slide presentation of ppt or pps format should be recorded using the recording function of the powerpoint. Afterwards, the slide show should be uploaded to the submission system with the article together.
The references cited must be articles which have been read by the author in person, and most of them (≧50%) were published in recent 3~5 years. The sequence should be the same as they appear in the article, a numerous mark with square brackets should be listed at right-up corner at the citation position, i.e., ***.
