Scientific and technical terms issued by the National Authorization Board for Scientific and Technical Terms，correct punctuations and legal units of measurement decreed by the State Department should be utilized.

Weight should be termed as mass(m，unit as“kg”);specific weight as relative density(d or ρ，unit as“1”or kg/cm3);molecular weight as relative molecule mass(Mr，unit as“1”)or molecule mass(m，unit as kg，and u is in common use，1 u≈1.660540 ×10－27kg);mol/m3is the unit of concentration，but mol/L，mmol/L andμmol/L are in common use;ppm had been abandoned，replaced by 10－6;Bq is the unit of radiation activity;Gy is the unit of radiation dosage.Time should be presented in a(year)，d(day)，h(hour)，min(minute)and s(second)as international symbols，while month and week have no uniform international symbols，which should be expressed as“月”and“周”in Chinese character.Manuscripts are strongly required to apply legal units of measurement，standard international symbols and correct lower-cases and capitals，for example，50毫克/(千克·天)should be 50 mg/(kg·d).Unit symbols must be in italic letters(pH is excepted)，while the symbols of vector and tensor should be in black italics.

Authors should be responsible for the accuracy of the data cited in the article.If necessary，statistical analysis should be carried out with SAS or SPSS software package.Statistical terms，symbols，number round-off，Chinese and English abbreviations should be standardized，for example，ˉx stands for arithmetical average，s for standard deviation，sˉxfor standard error，t means Student’s t test，F(xiàn) means F test，χ2means chi-square test，r means correlation coefficient，υ means degree of freedom，P means probability.All symbols should be in italics.Statistical test values such as t value，χ2value should be given before the expression of P value.

Numbers should be separated every three digits by a blank of 1/4 Chinese character rather than any symbol，for example，5000(not 5，000).Number ranges are expressed as follows:4-6 kg，5.2%-11.3%，4 ×109-10 ×109，36°-42°18'，(25.2 ±1.1)mm，(27±2)%.The round-off of number should abide by the principles that four is abnegated，six is added，five is fixed，odd number is added with carry and even number not.In general，retain two digits after a point.Multiplication of the numbers with unit should be written as follows:4 cm×3 cm ×5 cm，instead of 4×3×5 cm3.Century，year，month，day，time，and measurements should be expressed by using Arabic numerals.

Figures should be as few and concise as possible.Only reasonable，easily understandable and correctly designed figures will be accepted.Do not use a figure if language alone is enough to explain.Table of three-lined(top line，column line and bottom line)is acceptable，but boundary line can be drawn above bottom line if a portrait sum is needed.The results of statistical data analysis，such as t or P，can be included in a table，with or without notes below the bottom line of the table.Line diagrams should fulfill the following requirements:5∶7 ratio between height and width，and suitable size of 12.5 cm ×8.5 cm.The statistical figures should be presented in accordance with the data.Type figures in Word format in additional sheets.One figure and one table could be identified as Figure 1 and Table 1，but for multiple figures and tables，they should be numbered in Arabic numerals in the order in which they are presented in the text.

Photographs should be clear，high-contrast and high-resolution.Black-white or color pictures are accepted.In special instances，black-white or color positive films and negative films of radiographs，CT scans and slides are also adopted.For photographs of identifiable persons，written permission from the subjects must be supplied or the subject’s eyes will be masked.For histological microphotographs，original magnification and staining method should be indicated，and a scale marker，such as 1μm，should be noted in gross specimen pictures and in electronic microscopic pictures.

Titles and legends of the tables and photographs should be clearly typed on separate papers consecutively in Chinese and English simultaneously.Photographs should have the suitable size around 12.5 cm ×17.8 cm，identified with photograph number and arrows on the back to indicate the top side of the figures.

Discussion should be focused on new discoveries and conclusions and standpoints extracted from the study，closely surrounding the results from the study，rather than repeating the contents of the results.In the discussion，authors should purposefully compare their findings with and analyze the results cited in the previously published literature，rather than just review the literature.Conclusions should be based on reliable evidences，not guesswork nor conjecture.

Abbreviated terms:Abbreviated terms should not be used in title.When used in text，the full term should be presented at the first time it occurs which is followed by abbreviation and/or English term and abbreviation in bracket.

may be unlimited in number but must be recently published and have been read by authors.English references should be searched and selected from MEDLINE，EMBASE and Cochrane Library，and Chinese references should be searched and selected from CNKI，Wanfang database.The majority should be within the past 5 years.These original articles and literature cited by authors should be published formally rather than unpublished material，observations or personal correspondence，but the unpublished literature that has been accepted for publication can be listed as references with“in press”after the journal title.Citation from one article shouldn’t exceed 300 words，unless written permissions from the original authors are available.The journal compiles references in sequential coding format according to National Standard GB7714-87 of China.References cited should be identified by Arabic numerals set in superscript type in the text and its serial number should be matched with that listed in the Reference section.

The titles of journals should be abbreviated according to List of Journals Indexed in Index Medicus(1990)and the Abbreviation Manual of the World Medical Pharmacy and Chemical Journal titles(China Medicine and Science Press，1998).Sample reference are given below(please paying particular attention to the use of dot):
