Objective To analyze the structural,content and language characteristics of English abstract in domestic versus international geriatrics journals in order to promote international exchange in geriatric medicine research in our country.Methods In this paper,we analyzed the characteristics and contents of original articles published in 5 foreign journals (IF＞3.0) from Pubmed database (n=60) and 5 core (the source of statistics) domestic geriatric journals from Wanfang web during recent 3 years (n=61).Results Our survey showed that in the domestic geriatrics journals,the structured abstracts were used with inflexible four-heading and fixed leading words.In foreign geriatrics journals,however,non-structured abstracts were mostly applied in articles on basic research,and structured abstracts primarily appeared in clinical or survey research papers.Compared with foreign geriatrics journals,the shortages or some problems in English abstracts of the domestic geriatrics journals included a short writing,repetition of objective with title,lack of description of research background,improper description of results data,more passive voice,improper use of modal verbs.Conclusions The domestic geriatrics journals should learn the diverse forms of abstracts and content structure from foreign geriatrics journals,strengthen the elaboration of background and highlights,and use active voice in concordance with the international mainstream.

Objective To analyze the articles published in Chinese Journal of Geriatrics from 2008 to 2012 so as to understand the characteristics of published papers and research progress in geriatric medicine.Methods Based on Wanfang database,bibliometric analysis was conducted to analyze the quantity,types,authors,affiliations,fund support of all the articles published from 2008 to 2012 in Chinese Journal of Geriatrics.Results A total of 1567 papers were published in the journal from 2008 to 2012.The column with the most published papers was clinical research (1008 papers,64.3 ％),followed by experimental researches,reviews and lectures,investigations etc.The discipline with the most articles published in the journal was cardiovascular medicine,followed by surgery,neurology; respiratory etc.1356 authors from 506 affiliations published paper as the first author in the journal during this five years,with the maximal number being 7 papers and the major affiliation being affiliated hospitals of medical colleges (733 papers,49.3 ％).Authors from Beijing,Zhejiang,Jiangsu,Shanghai published more papers than those from other provinces.29.0％ (455papers) of the total papers were supported by fund,among which the majority was provincial fund,followed by national fund,municipal fund,ministry fund and military fund.Conclusions A relatively stable core author group has formed for Chinese Journal of Geriatrics,and the articles are of high quality.Chinese Journal of Geriatrics is one of the highest academic journals in geriatric medicine.

Objective To understand the research status and development tendency of domestic geriatrics.Methods To analyze all the key words in the academic articles from five representative Chinese journals of geriatrics from 2009 to 2013 through key words frequency analysis.Results From 2009 to 2013,the 55212 key words in 15314 articles were analyzed.The percentages of the articles indexing 3,4 and 5 keywords were 39.3％ (6012/15314),33.3％ (5092/15314) and 13.9％(2123/15314),respectively.There were 45 high-frequency keywords,among which 17 key words (37.8％) were in the top 30 every year.The main research object of geriatrics was Aged,the main research contents were common diseases in the elderly,including Diabetes Mellitus,Coronary Artery Disease,Alzheimer's Disease,Hypertension,Cerebral Infarction,Cognition Disorders and etc.The Risk Factors,Therapeutics and Prognosis of these common diseases were always explored.Co-words analysis showed that there were 51 pairs of key words with a frequency more than or equal to 20.Conclusions The hot-spot of geriatric research in our country is relatively concentrated.We should pay attention to body disease,and focus on the mental health problems in the elderly.

Objective To analyze the literature distribution and research status of depression in the elderly published in Chinese Medical Association journals.Methods The literatures of elderly depression published in 85 kinds of Chinese Medical Association journals from 2003 to 2012 were collected.The publication year,distribution,content,author,institution and region of these literatures were analyzed.Results From 2003 to 2012,there were 85 articles on depression in the elderly published in 15 kinds of journals of the Chinese Medical Association.These literatures were published mostly in 2011 (18 articles,21.2％),secondly in 2010 (13 articles,15.3％) and 2012 (12 articles,14.1％),which were published mostly in Chinese Journal of Geriatrics (29,34.1％).These articles mainly included basic science,inventory survey,diagnostic methods and clinical treatment strategy,and the most published form was treatise (77 articles,90.6％).The author who published the most articles was YUAN Gui yong from Nanjing (3 articles,3.5％),the institution which published the most articles was People's Hospital of Hainan Province (4 articles,4.7％),and the provinces or cities which published the most articles were Beijing (15 articles,17.6％),Shandong (9 articles,10.6％) and Zhejiang (7 articles,8.2％) by turns.Among the 85 articles,31 articles (36.5％) were supported by foundations.The definition,epidemiology,mechanism,influence factors,clinical characteristics,diagnosis and treatment strategy of elderly depression,and especially secondary depression were well discussed in these literatures.Conclusions The literatures of elderly depression published in Chinese Medical Association journals are insufficient in quantity,and more than half of the literatures are published from 2010 to 2012.The distribution of journals is relatively concentrated,but the distribution of author,institution and region in these articles is dispersed.Secondary depression in the elderly is concerned especially.

Objective To investigate the situation and development of international literatures on geriatrics and gerontology in mainland China.Methods The literatures on geriatrics and gerontology written by mainland Chinese scholars as the first author were selected from Thomson Scientific database in 1979-2011 period.Researches on basic theory,summary reports of clinical practice and reviews were collected.The quantity of published articles,article types,international cooperation research and funding programs,hospital rankings,as well as the 2011 geriatrics professional journals,thesis topic disciplines distribution and high-performance papers were analyzed by Thomson Data Analyzer software.Results From 1979 to 2011,the quantity of literatures written by Chinese scholars as the first author (not including Hong Kong,Macao and Taiwan regions) was 1927,including 1769 research articles,86 reviews,18 editorials,54 letters.Average paper was cited 7.6 times and the average number of article citation was 30.6.International cooperation research articles occupied 379 (19.7 ％).Articles with research sponsorship were 734 (38.1 ％),in which most subject discipline was geriatric and gerontology.Conclusions The development of geriatric medicine in China is rapid.The international scientific and technological cooperation is very extensive.It is important to further improve the world impact of geriatric medicine from China.The development of geriatric medicine in a large,cooperative,comprehensive,interdisciplinary,interagency direction,and the prospective,multicenter,cooperative study need to promote.It is extremely urgent to establish the English version of Chinese journals of geriatrics with a international influence.

Objective To explore the distribution and research status of literatures on Alzheimer disease (AD) published recently,to compare the differences in the research papers on AD between China and foreign countries,and to provide bibliometrics data for Alzheimer disease research.Methods Using bibliometrics methods,the characteristics and contents of Alzheimer disease research documents were analyzed in Pubmed database and Wanfang web by analysis tools.Research status of Alzheimer disease including the type of literatures and journal distribution from 2008 to 2012 was analyzed.Currently hot topics or top high frequency words were emphatically analyzed.Results There were 646 matched literatures for Alzheimer disease retrieved in Chinese core periodicals,and 19 423 literatures in Pubmed database.The articles for clinical study of Alzheimer disease were more than experimental and epidemiologic study among the 646 literatures.The disciplines distribution of AD in Chinese core journals was similar to international journals,mainly including nerves,brain,and geriatrics journals.The domestic research papers on Alzheimer disease were less than 5％ in Pubmed database,and the articles from Chinese journals in Chinese or English edition accounted for only a small proportion of Pubmed database.The recent research direction of Alzheimer disease in China was similar to foreign countries such as amyloid proteins,diagnosis and gene,but foreign research paid more attention to the metabolism,image and the aging mechanism in AD,while in China there were quite a lot of reports in the literatures on cholinergic drugs,tau protein,hippocampus and Chinese herbal treatments.Conclusions The AD-related disciplines distribution in China and foreign country is relatively fixed in recent 5 years.The AD researches carried out in China are close to those in foreign country,but researches on some areas still lag behind.The experimental and epidemiologic study on AD should be strengthen in China.

Objective To analyze the citation status of Chinese Journal of Geriatrics,and to evaluate the authority and quality of this journal.Methods Literatures including original research articles,short reports of original studies,reviews and clinical case reports etc.from 2003 to 2007 were collected from China national knowledge internet (CNKI) and Wanfang Database.The citation frequency,author distributions,relevant journals and foundation status were statistically analyzed.Results Totally 1649 papers were published in Chinese Journal of Geriatrics from 2003 to 2007,among which 1280 papers were cited 9062 times by 946 kinds of journals,the average citation times was 7.08 times,and the top citation times was 131 times.270 articles were cited 10 or more times (21.09％).The top 3 relevant journals with high citations from Chinese Journal of Geriatrics were Chinese Journal of Gerontology,Chinese Journal of Geriatrics and Chinese Journal of Misdiagnostics (totally 591 times,6.52％).The self-citation rate was 1.95％.445 articles were supported by different kinds of funds (totally 112 kinds),and majority of articles were supported by National Natural Science Foundation of China.Articles supported by 106 kinds of funds were cited and the total citation times was 2312 times.Conclusions Literatures in Chinese Journal of Geriatrics have high quality and authority with an amount of readers and relatively stable relevant journals.Journal quality and academic level are highly improved,but further efforts are needed to promote the coordinated development of regions.

Objective To develop a scientific system of core information of health and evaluation index for the elderly Chinese people,which is suitable for the situation of our country.Methods The framework was established by extensive literature review and topic discussions.The index system was constructed with the Delphi method.Results 58 experts in different fields of health were selected in the two rounds of Delphi consultation research.The effective response rates in the two rounds were 96.88％ and 100％ respectively.The average value of the authoritative coefficient was between 0.80 and 0.96.And coefficients of variation were between 6.20 and 12.13.Based on the Delphi consultation research,the core information of health and evaluation index system for the elderly Chinese people were composed of 8 primary indicators closely associated with the positive awareness of aging and senescence and 31 other indicators.Conclusions The architecture of the core information of health and evaluation index system for the elderly Chinese people is stable,and the consultant experts tend to reach a consensus.The evaluation index system contains the most influential factors for the elderly Chinese people,and has the affirmative scientificity,applicability and feasibility.

Objective To evaluate the reporting quality of Meta-analyses published on Chinese journals of geriatrics.Methods Papers of Meta-analyses on geriatrics published in nine major Chinese journals of geriatrics before November 21,2013 were retrieved,their basic information were abstracted and evaluated through system assessment and preferred reporting items for systematic reviews and Meta-analyses (PRISMA) statement.Statistical analyses were performed with the SPSS17.0 software.Results Among the 71 internalized papers,1 was from 《Geriatrics & Health Care》,1 from 《Practical Geriatrics》,10 from 《Chinese Journal of Geriatric Care》,45 from 《Chinese Journal of Gerontology》,3 from 《Chinese Journal of Multiple Organ Diseases in the Elderly》,1 from 《Chinese Journal of Geriatric Dentistry》,5 from 《Chinese Journal of Geriatric Heart Brain and Vessel Diseases》,5 from 《Chinese Journal of Geriatrics》.55 papers (77.5％) were published in recent 3 years.The mean overall PRISMA score was(16.75±3.04)ranged from 4 to 24.The main influencing factor for the quality of Meta-analyses was the year of publication (adjusted β=-0.342,P=0.003).Conclusions The quantity and quality of Meta-analyses published on Chinese journals of geriatrics are increased and improved in recent years,but there are still some problems on the writing norms.We should promote PRISMA statement and standardize reporting format to improve the quality of Meta-analyses in the field of geriatric medicine.

Frailty is a geriatric syndrome that has been implicated as a causative and prognostic factor for cardiovascular disease (CVD).Frailty and CVD are often concurrent and mutually promotive.The prevalence of frailty ranges from 10％ to 60％ in patients with CVD,depending on different tools and cutoffs chosen to define frailty.Short-and long-term prognosis of CVD are both affected by frailty.The presence of frailty is correlated with an increase in complications,outpatient and emergency department visits,hospital admissions and stays,and mortality in patients with CVD.Early prevention and clinical intervention can delay or even reverse the development of frailty,thus improving the prognosis for CVD.
