Résumé
Scutellariae Radix is one of the most popular Chinese mateira medica (CMM) with a long history, commonly used for heat-clearing and damp-drying. In this paper, based on the characteristics of CMM, the retrieval strategy was formulated. Then, the global patent data of Scutellariae Radix were retrieved from Innography. A total of 23 426 patents related to Scutellariae Radix have been retrieved worldwide. A set of statistical and bibliometric methods has been used to analyze the technical competition situation from the aspects of development trend, global patent layout, research and development hotspots, core patents and other aspects. The analysis results showed that the patent technology life cycle of Scutellariae Radix is in a rapid growth period. The R&D focuses on prescriptions, health products, and tea drinks of Scutellariae Radix. Four countries, including China, Japan, USA, and South Korea, are the main sources of technology, as well as the most important patent layout. Scutellariae Radix industry has a unique regional development advantage, especially in East of China, Beijing, Tianjin, and Sichuan. From the perspective of development trend, there is a broad space for the development of Scutellariae Radix industry.
Résumé
The retrieval of literature novelty assessment projects was divided into unlimited retrieval and limited retrieval according to the retrieval terms.The redundant retrieval mode,complicated retrieval process,poor compatibility,and lack of summary that affect the retrieval effectiveness of literature novelty assessors were analyzed.The overall retrieval ability and literature analysis ability of literature novelty assessors were put forward for improving their retrieval effectiveness.
Résumé
Objective To investigate a retrieval strategy for dentistry literature based on medical subject headings (MeSH). Methods We analysed the MeSH Tree Structures of PubMed in 2009 and combined it with the core glossary of dentistry to find out highly frequent dental words in MeSH. Then 6 words were singled out from the whole MeSh Tree to apply for a retrieval strategy for dentistry literatures. Results 102,500 pieces of dentistry literature were obtained from the year 2006 to 2008. Conclusions This research strategy can improve the efficiency of literature search in dentistry field for clinical or laboratory researches.
Résumé
Aim To study the application status of odds ratio for medical animal experiments.Methods Odds ratio and seven kinds of animal models were used as retrieval strategy to search medical animal experiment related papers in several Chinese and English databases.Papers relating to each kind of animal model and using odds ratio in abstract and text were counted. Data from different databases were compared. Calculation of odds ratio was exemplified and the significance of different odds ratio values was illustrated in this paper.Results Few medical animal experiments cited odds ratio as statistics.Conclusions The importance of odds ratio has not been fully recognized in Chinese references.
Résumé
The paper expounds the function and significance of establishing CBM retrieval strategies for commonly used words, it could not only promote the quality and efficiency but also have important significance to upgrade and standardize the quality of novelty as-sessment report.
