| Object:To know the situation of the biomedical journal inclusion in the PubMed database in China, understand the opportunities and challenges for the development of Chinese journals. To analysis the basic characteristics of periodicals included in the PubMed database according to the subject, provides the countermeasure and suggestion to the journals not included in the PubMed database; To analyze the citation frequency of the Chinese biomedical journals that included in SCI database, understand the international influence of the biomedical journals in our country.Subjects and Methods:Sort 130 kinds of biomedical journals included in PubMed database and analyze the measurement indexes of the journals according to the 2011-2015 edition of the China science and technology journal citation reports (KuoKan edition), except for 46 kinds with incomplete information (not included Hong Kong, Macao and Taiwan journal" report"), the last 84 domestic journals with complete data are included in our study. According to "the China science and technology journal citation reports (2014 edition)" (KuoKan version),84 kinds of biomedical journals are divided into 18 categories, including 16 biology journals,12 basic medical journal,8 Chinese medical journals,7 surgery journals,6 university (medical) journals,5 preventive medicine and hygiene journals,4 eye and otolaryngology science journal,4 general journals of medicine and health care,3 journals of obstetrics and gynecology and pediatrics,3 oral medical journals,3 journals of internal medicine,3 kinds of oncology journals,3 kinds of pharmaceutical, environmental and safety science periodical 2 kinds of each, clinical medicine, special medicine, chemistry, history,1 kind of each. There are 12 class discipline containing more than 3 kinds of journals (including 3 kinds),76 kinds of journals in total.Analyze the basic information of PubMed included 130 kinds of Chinese biomedical journals, conduct descriptive statistics analysis to the basic situation of the discipline containing more than three (including three) kinds of journals,76 kinds of journals not included in PubMed database are chosen as the control based on their discipline.By the methods of literature, literature metrology,76 kinds of journals included in PubMed database and 76 kinds of journals not included in PubMed database are used as the research object, the China science and technology journal citation reports (KuoKan version) and the SCI database are used as the data source,7 citation index of the China science and technology journal citation report of the journal evaluation index are set as indicators, including total cited frequency, impact factor, annually index, cited rate, subject influence index, cited half-life, H index, and the source of five indicators:source literature quantity, average citation number, the average number of authors, fund papers, cited half-life. Using Excel and SPSS software for statistical analysis and comparative study, the use of statistical methods including descriptive statistics analysis (mean and standard deviation), spearman correlation analysis, two independent samples nonparametric tests, etc.Results:1. China biomedical journals included by PubMed database showed a trend of concentration.The inclusion of China biomedical journals in PubMed database showed a regional concentration tendency. PubMed included 130 journals in our country,67 were published in Beijing, Shanghai, possessing more than half of the total number, which related to the resources distribution of science and technology. A large percentage of science and technology are distributed in economically developed cityies, such as Beijing and Shanghai. Science and technology journals reflect that scientific and technological achievements will pursue the development of science and technology resources.The inclusion of China biomedical journals in PubMed database showed a subject concentration tendency.84 kinds of journals included in PubMed database were divided into 18 categories according to their subject,49 kinds of journals were associated with biology, basic medicine, Chinese medicine, surgery, journal of university (medical), occupying 58% of the total number of periodicals.In the prospect of journal publication, biomedical journals include in PubMed database in China have a central tendency of internationalization development. Analysis included in PubMed database periodical publishing organization,43 kinds of periodicals have more than two (including two) periodical publishing organization. Thirty-six kinds of periodicals have cooperation with foreign press and publishing group, such as overseas publication, online publication, joint publication, accounted for nearly one third of the total number journals. Twenty-one species of periodicals have cooperation with Elsevier, Wiley-Blackwell and Springer. The number of journals which have cooperation with foreign publication institutions was around 58%.2. Domestic biomedical journal included in PubMed database areexcellent journal in China.Through analysis the measurement indicators of domestic journals include in PubMed database, we found that the PubMed database included interdisciplinary journal reference index and source index were better than the overall level of Chinese biomedical journals. The level of cited frequency, impact factor, annually index, cited rate, subject influence, cited half-life, H index, the average number of citations, the average number of authors, fund and paper of most journals included in PubMed database is higher than the overall average discipline biomedical journals in China; The citation half-life is an "the smaller the better" indicator, the average level of the cited half-life of journals included in PubMed database is below the average level of biomedical journals in our country. This indicates most journals include in PubMed database are excellent in the interdisciplinary journal.In the journals included in PubMed database, only the level of journals from oral medicine, internal medicine, eyes, ears, nose and throat source of scientific journals literature are slightly higher than the overall level of average amount of biomedical journals, which is contradictory to some scholars’conclusion "high academic quality science and technology journals have a large number of papers articles, large source of literature, authors with high academic level, and science and technology journal reviews articles with high standard". The impact of literature source and amount on the influence of a journals remains to be discussed.3. The development of the journals include in PubMed database is unbalanced.To understand the development of journals included in PubMed database, according to the principle of "bigger is better", select the cited frequency, impact factor, annually index, discipline influence, the average number of citations, H index as indicator, six indexes of 12 classes subject are assigned from big to small.As the data shown:the score of basic medical, biology, oral medicine, general surgery, medicine and health care, eye, ear, nose, throat are below the average level of science, the score of basic medical is the lowest, each indicator is in a low level. Analyze the reason, several factors should be considered:first, it is associated with the characteristic of the journal, such as the oral medicine, eye otolaryngology journal belong to minority academic journals, and the general journals of preclinical medicine, biology, medicine, health journals lean to basic research, journal nature determines the journal development is not balance; Second, the journal development is closely related to the discipline development. The lower scores of the journals partially reflect the immaturity of the medical discipline, lack of high-impact journal; Third, the development of the journal are closely associated with government policy, low scores may be related to the insufficient national support.On the other hand, the scores of college journals, journals of preventive medicine and hygiene, Chinese medicine, internal medicine, oncology, journal of obstetrics and gynecology and pediatrics disciplines are higher. Analyze the reasons, in addition to the discipline characteristics, the development degree of discipline, government support, the research hotpot of science and technology research, social awareness are closely related. Traditional Chinese medicine as one of the world’s rare traditional medicine, because of its unique theoretical system and medical culture, has been included in PubMed database in the early 1980s. Journal of preventive medicine and hygiene are well developed with good quality of academic influence, obtained more and more attention these years, mainly affected by the national health policy. The 2012 health policy reform goals clearly required:medical and health undertakings in our country will move forward step by step, gradually attaches great importance to the prevention work to improve people’s health level. This policy promotes the government to increase the investment in prevention of related research, so as to promote the development of the discipline. In addition, the development of preventive medicine and hygiene and the development of Chinese medicine are closely related to the improvement of people’s understanding of health and disease. At present, the cancer is a hot research topic around the world. In terms of oncology journals, there are 38 kinds of oncology journals in our country, three of which are included in by PubMed database, two are in SCI database, showing its fast development.4. Inclusion in the PubMed database plays an important role in promoting medical journal international influence.Through the comparison between the journals’ citation rate included or not included in PubMed database, inclusion into PubMed database play an important role in improvement of medical journal international influence. Four aspects should be included:PubMed database is the world’s most authoritative biomedical database, medical journals to be included in the PubMed database for its has important scientific value, to improve the international influence and increase the citation frequency; PubMed database offprint principle emphasis advance and originality on content, to some extent, more practical than the SCI database. Its university of use and authority of content for the medical journals included in the PubMed database have higher international reference frequency; After the Medical journals are selected by PubMed database, it is easier for them to attract high-quality articles, make the development of journals into virtuous cycle; In terms of language, medical journals included in the PubMed database have abstract both in Chinese and English journals, which is convenient for the readers, to a certain extent, also improved the journal international citation rate.Conclusion:Inclusion in SCI database has significant role in promoting journal’s international influence, but requires higher language level,most biomedical journal of in China are Chinese journals, so except for the basis construction of the academic level of our journals, we should seek the path for ascension of journal’s international influence and cited-rate. There is a long journey for the development of periodicals in China, inclusion in SCI database is one of the ways to promote journals’international influence, we need to seek for other ways, such as medical journals included in database such as PubMed, attaches great importance to the quality of journal edition, strengthen cooperation with foreign academic institutions and publishers. In addition, aiming at the existing problems in the development of periodicals, we should positively face the trend of international competition, also need the joint efforts of the people and the scholar, adjust the structure of biomedical journal subject, make its disciplines distribution corresponding to biomedical development; construct competitive journal, sets up the periodical internationalization trend, improve the academic quality of journals, attaches great importance to the journal editor published specifications, actively in line with the international standards; Establish and improve the biomedical journal evaluation system, fully considering the journal of international influence; Gradual reform of academic evaluation system in China, transform the international competition of Chinese academic journals. |
