Objective To analyze statistically the international impact of the Chinese Sci-tech TOP journals published from 2011 to 2015, so as to provide solid evidences for the foundation for the exploration of the regulatory institutional mechanism and devel -opment of China′s outstanding Sci-tech journals .Methods Based on the data from the Annual Report International Citation of Chinese Academic Journals from 2012 to 2016, the international total citation (TC), international impact factor (IF) and international clout in-dex ( CI) of TOP 5%and TOP 5%-10%journals of in Chinese Sci-tech field in 2011-2015 years were statistically analyzed .Results The international impact of TOP journals in Chinese Sci-tech field from 2011 to 2015 increased year by year , the average TC of TOP 5%journals increased by over 10%annually, and that of TOP 5%-10%journals increased by over 20%annually.The average IF all increased by over 20%annually, and the number of SCI and English journals also increased year by year .The international influence of some non-SCI journals , including Chinese non-SCI journals , surpassed that of certain SCI journals by a larger margin , which deserved further study and analysis .Conclusion To further expand influence of academic journals , the editorial boards of related journals should devote more efforts to attract high quality papers so as to build high caliber publishing platforms .In addition , bilingual publication might be a better form for global dissemination of journals , and the rapid rise and development of language translation software and intelligent translation might contribute to the solution of the problem .

A 26-year-old male presented with a 6-day history of paroxysmal headache which was worsen with nausea and vomiting for 1 day. Head CT on admission revealed left chronic subdural hematoma with midline shift. An emergency Burr hole drainage for hematoma was performed. Headache recurred 6 days later. MRI of the brain revealed a diffuse thickening and a gadolinium-enhancement of the falx, cranial dura mater and tentorium cerebelli on the left side with pia mater involved. Lumber puncture showed increased intracranial pressure and elevated IgG level in cerebrospinal fluid. Histological examination of the biopsy specimen showed thickened, fibrotic dura with a sterile chronic inflammation. According to pathological examination, idiopathic hypertrophic cranial pachymeningitis was considered as the final diagnosis. Symptoms were improved with steroid pulse therapy.

Objective To conduct a preliminary analysis on HBO research in China from 2010 to 2014,so as to provide evidence for the development of the discipline.Methods Information retrieval was made by using Chinese Biomedical Disk (CBM) as the chief source of information.Through the approach of bibliometrics,analyses were made on the year distributions of literature,the amount of literature published within the years,the regional distributions of authors,institutions and related journals concerning HBO research from 2010 to 2014.Results The amount of papers published from 2010 to 2013 was generally stable,but with a slight decrease in 2014.Analyses of regional distribution of authors indicated a downward trend from the higher distribution in the east coastal areas to the lower distribution in the mid-west inland areas.Nine institutions that have more than 15 contributions within the said years are basically located in Beijing,Shanghai,Guangzhou and other highly developed coastal and river basin areas with rich water resources,with hospitals as the main research bodies.Subject analyses suggested that researches concerning HBO research were mainly focused on the toxication of carbon monoxide,the treatment of such diseases as cerebral infarction,craniocerebral injury,sudden hearing loss,diseases of newborns,coma,loss of consciousness,cerebral ischemia,spinal cord injury,cerebral hemorrhage,diabetes foot,etc.,as well as its application in the rehabilitation of patients following surgery.The Chinese Journal of Nautical Medicine and Hyperbaric Medicine as the core periodical in the field of HBO research,is the one that has the largest amount of papers published within the years,with the medical journals on neural diseases and rehabilitation coming next.Conclusions Great progress has been made in the research and application of HBO in recent years,which is mainly manifested in the treatment of diseases that are more susceptible to HBO therapy.However,most papers are on clinical applications,few papers are associated with basic research.On the other hand,significant differences could be noted in the regional distribution of author population and research institutions.

Objective To perform information visualization analysis on the papers published,research hot points and network relationship concerning "Nautical Medicine and Hyperbaric Medicine",so as to provide reference materials for the establishment of the visualization analysis method of the source data in the said military medical journal.Methods By using the papers collected in the China Science and Technology Journals Database (CQVIP) as a statistical source,statistical analysis of the 1337 articles published in the journal fiom 2004 to 2011 was made accordingly.Statistical method was further used to analyze the quantity of papers published,columns classification,the number of contributions and the state of author cooperation.Bibexcel software was used to generate keyword co-word matrix,and SPSS software was also used to perform clustering analysis,and NetDraw was used to draw a network map.Results The number of papers published per issue in the journal was 30.4,with cooperative rate of coauthors being 90.5％,the authors'cooperation rate being 4.28,the institutes'cooperation rate 1.55 and the Price index being 24.7％.Facts revealed that there were 2 core institutions and 3 hot research areas.Conclusions Through bibliometrics and keyword co-word matrix generated by Bibexcel,the main research institutions concerning nautical medicine and hyperbaric medicine were military research institutes,military hospitals and universities.Their main research hot points were nautical medicine,diseases induced by anoxia and gas poisoning.Team cooperation was the main research mode,which displayed the toughness and high academic level of the discipline involved in the research.At the same time,it could provide a new approach for the information visualization analysis of the source data of military medical journals.

Objective To get a more comprehensive knowledge of the Chinese Journal of Nautical Medicine and Hyperbaric Medicine through analysis of the bibliometric data published in the journal from 2009 -2013,so that readers will have a profound knowledge of the journal and it will also facilitate the editorial board to improve the academic level of the journal by drawing experience from others.Methods With the scientific papers published in the journal from 2009-2013 as research subjects,in reference to " the Citation Report of the China Science and Technology Journals" between the years of 2010-2014,and through the approach of bibliometrics,statistical analyses were made on the amount of papers published,the citation frequency,influential factors,foundation thesis ratio,regional distribution and other data in recent 5 years.Results With regard to the amount of papers published,the yearly amount tended to decrease year by year,but with that of 2013 increased slightly.(2)Concerning citation frequency,total citation frequency on the whole tended to increase year after year,i.e.the yearly index of 2011 increased considerably,but the indexes of 2012-2013 tended to be stable.(3)With respect to influential factors,the factors derived from the 2000-2011 issues were relatively low,but the influential factors in the 2012 and 2013 issues were increased quite considerably.(4)With respect to foundation thesis ratio,the highest value of 2012 was 0.38,while the lowest value of 2013 was 0.128.As could be seen,there was great fluctuation.(5)Concerning regional distribution,the papers published in the journal in the recent 5 years were from about 90 institutions or organizations of 20 provinces,autonomous regions and municipalities directly under the central government.(6)The average number of authors per paper each year was over 4.Conclusions The Chinese Journal of Nautical Medicine and Hyperbaric Medicine is the only core periodical in the fields of nautical medicine,hyperbaric oxygen and diving medicine,and is also an important platform for physicians,scholars and research workers to exchange knowledge and experience in these fields.Bibliometric statistics and analysis of the papers published in the recent 5 years definitely reflect the development status and trend of the journal,which is of great significance to better improvement in the work of the editorial department and further progress in development of the discipline as well.
