Text
For most article types, the main text should be structured into the
following sections: INTRODUCTION, MATERIALS AND METHODS,
RESULTS and DISCUSSION, and should include in appropriate Figures
and Tables. Data should be presented in the body text or in Figures and
Tables, but not in both.
Illustrations
Figures should be numbered as 1, 2, 3 and so on, and mentioned clearly in
the main text. Provide a brief title for each fi gure on a separate page. No
detailed legend should be involved under the fi gures. This part should be
added into the text where the fi gures are applicable. Digital images: black
and white photographs should be scanned and saved in TIFF format at a
resolution of 300 dpi; color images should be saved as CMYK (print fi les)
but not as RGB (screen-viewing fi les). Place each photograph in a separate
fi le. Print images: supply images of size no smaller than 126 mm×76 mm
printed on smooth surface paper; label the image by writing the Figure
number and orientation using an arrow. Photomicrographs: indicate the
original magnifi cation and stain in the legend. Digital Drawings: supply fi les
in EPS if created by freehand and illustrator, or TIFF from photoshops.
EPS fi les must be accompanied by a version in native fi le format for editing
purposes. Existing line drawings should be scanned at a resolution of 1200
dpi and as close as possible to the size where they will appear when printed.
Please use uniform legends for the same subjects. For example: Figure 1
Pathological changes of atrophic gastritis after treatment. A: …; B: …; C: …; D:
…; E: …; F: …; G: …
Tables
Three-line tables should be numbered as 1, 2, 3 and so on, and mentioned
clearly in the main text. Provide a brief title for each table. No detailed
legend should be included under the tables. This part should be added into
the text where the tables are applicable. The information should complement
but not duplicate that contained in the text. Use one horizontal line under the
title, a second under the column heads, and a third below the Table, above
any footnotes. Vertical and italic lines should be omitted.
Notes in tables and illustrations
Data that are not statistically significant should not be noted. aP<0.05,
bP<0.01 should be noted (P>0.05 should not be noted). If there are other
series of P values, cP<0.05 and dP<0.01 are used. Third series of P values
can be expressed as eP<0.05 and fP<0.01. Other notes in tables or under
illustrations should be expressed as 1F, 2F, 3F; or some other symbols with
a superscript (Arabic numerals) in the upper left corner. In a multi-curve
illustration, each curve should be labeled with ●, ○, ■, □, ▲, △, etc. in a
certain sequence.
Acknowledgments
Brief acknowledgments of persons who have made genuine contributions
to the manuscripts and who endorse the data and conclusions are included.
Authors are responsible for obtaining written permission to use any
copyrighted text and/or illustrations.
REFERENCES
Coding system
The author should code the references according the citation order in text
in Arabic numerals, put references codes in square brackets, superscript it
at the end of citation content or the author name of the citation. For those
citation content as the narrate part, the coding number and square brackets
should be typeset normally. For example, Crohn’s disease (CD) is associated
with increased intestinal permeability[1,2]. If references are directly cited in the
text, they would be put together with the text, for example, from references
[19,22-24 ], we know that…
When the authors code the references, please ensure that the order in
text is the same as in reference part and also insure the spelling accuracy of
the fi rst author’s name. Do not code the same citation twice.
PMID requirement
PMID roots in the abstract serial number indexed by PubMed (http://www.
Ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed). The author should supply
the PMID for journal citation. For those references that have not been
indexed by PubMed, a printed copy of the fi rst page of the full reference
should be submitted.
The accuracy of the information of the journal citations is very
important. Through reference testing system (http://www.aushome.cn/cgibin/
index.pl), the authors and editor could check the authors name, title,
journal title, publication date, volume number, start page, and end page. We
will interlink all references with PubMed in ASP fi le so that the readers can
read the abstract of the citations online immediately.
Style for journal references
Authors: the fi rst author should be typed in bold-faced letter. The surname
of all authors should be typed with the initial letter capitalized and followed
by their name in abbreviation (For example, Lian-Sheng Ma is abbreviated
as Ma LS, Bo-Rong Pan as Pan BR). Title of the cited article and italicized
journal title (Journal title should be in its abbreviation form as shown in
PubMed), publication date, volume number (in black), start page, and end
page [PMID: 11819634]
Note: The author should test the references through reference testing
system (http://www.aushome.cn/cgi-bin/index.pl)
Style for book references
Authors: the fi rst author should be typed in bold-faced letter. The surname
of all authors should be typed with the initial letter capitalized and followed
by their name in abbreviation (For example, Lian-Sheng Ma is abbreviated as
Ma LS, Bo-Rong Pan as Pan BR) Book title. Publication number. Publication
place: Publication press, Year: start page and end page.

Inappropriate references
Authors should always cite references that are relevant to their article, and
avoid any inappropriate references. Inappropriate references include those
that are linked with a hyphen and the difference between the two numbers at
two sides of the hyphen is more than 5. For example, [1-6], [2-14] and [1, 3,
4-10, 22] are all considered as inappropriate references. Authors should not
cite their own unrelated published articles.
Statistical data
Present as mean ± SD and mean ± SE.
Statistical expression
Express t test as t (in italics), F test as F (in italics), chi square test as χ2 (in
Greek), related coeffi cient as r (in italics), degree of freedom as γ (in Greek),
sample number as n (in italics), and probability as P (in italics).
Units
Use SI units. For example: body mass, m (B) = 78 kg; blood pressure,
p (B) = 16.2/12.3 kPa; incubation time, t (incubation) = 96 h, blood glucose
concentration, c (glucose) 6.4 ± 2.1 mmol/L; blood CEA mass concentration,
p (CEA) = 8.6 24.5 μg/L; CO2 volume fraction, 50 mL/L CO2 not 5% CO2;
likewise for 40 g/L formaldehyde, not 10% formalin; and mass fraction,
8 ng/g, etc. Arabic numerals such as 23, 243, 641 should be read 23 243 641.
