RESUMO
The classification for papers on research of basic and clinical medicine was studied using the MeSH and check tags indexing rules according to the NIH definition of research on clinical medicine based on PubMed, and its scientificalness was verified according to the papers published in New England Journal of Medicine, Lancet, and Journal of American Medical Association from 2006 to 2015. The classification is of realistic significance for the scientific research management departments to keep abreast of the status quo and level of research on basic and clinical medi-cine and to make policy of scientific research management.
RESUMO
BACKGROUND:As the latest generation of ultrahigh molecular weight polyethylene, vitamin E-stabilized ultrahigh molecular weight polyethylene has been widely put into use of various kinds of joint replacement. However, wear debris and osteolysis caused by that are stil the vital factor influencing the clinical curative effect. OBJECTIVE:To discuss and summarize the material characteristics and application progress of vitamin E-stabilized ultrahigh molecular weight polyethylene, and to seek the theoretical basis which can guide us to launch vitamin E-stabilized ultrahigh molecular weight polyethylene clinical y. METHODS:The first author retrieved the CNKI and Medline databases by computer. The keywords were“ultra-high molecular weight polyethylene, vitamin E-stabilized, joint replacement, application”in English. RESULTS AND CONCLUSION:Total y 92 articles were retrieved. According to the inclusion and exclusion criteria, 46 articles were included in result analysis. The results show that vitamin E-stabilized ultrahigh molecular weight polyethylene can not only enhance the physicochemical property of prosthesis, but also can integrate with free radicals to increase antioxidant rate of prothesis in order to prolong the long-term curative effect of prosthesis. However, it is stil lack of vast of clinical cases and fol ow-up as evidence. In case of that, long-term clinical efficacy remains to be assessed.
RESUMO
Objective To study the term selecting principles and methods for TCM function classification of the Chinese Traditional Medicine and Materia Medica Subject Headings;To provide basis for revision of new terms.Methods According to general rules of vocabulary compiling and word frequency statistics, relevant database retrieval results and some other materials, such as Chinese Pharmacopoeia (2010 edition), Chinese Medicine Dictionary and Chinese Materia Medica, were referred to conduct the study on the terms of TCM function classification in 2008, and then the subject headings were determined.ResultsThe table of TCM function classification has 1679 subject headings, among which 39 are planned to be deleted, 135 are to be added and 8 are to be modified. Adjustment of these subject headings is conducted according to the efficacy classification of TCM.ConclusionNew version of TCM function classification subject headings are mainly according to word frequency. The subject headings are mainly classified according to main efficacy of TCM, with a purpose to avoid redundancy.
RESUMO
Background: Endometriosis is one of the common gynaecological problems mostly affecting the women in reproductive age, associated with non menstrual pelvic pain and other symptoms and recurrence of endometriosis is common after medical or even surgical treatment. Objectives: This review is done to assess, whether conservative surgery and adjunctive hor- mone suppression therapy is more beneficiary than surgery alone in the treatment of sympto- matic endometriosis in term of pelvic pain and disease recurrence. Data sources and search method: Searched had been performed on Cochrane Central Register of Controlled trials, MEDLINE, PsycINFO. Journals and reference lists had been also searched. Review methods: Only Randomized controlled trials were included if they compared the effec- tiveness of hormone therapy following conservative surgery with surgery alone or surgery plus placebo in the treatment of symptomatic endometriosis. Outcome data had been analysed by using a Mantel-Haenzel Fixed-effect model to perform meta-analysis and results had been pre- sented as Risk ratio for binary data and Standardised Mean difference for continuous data with 95% confidence intervals. Results: Out of 8 trails pelvic pain was reported in 7 trials. No significant benefit was observed both in pelvic pain recurrence (RR= 0.75, 95% Cl- 0.54 to1.04) and disease recurrence (RR 0.89, 95% Cl 0.53 to 1.49) among 5 trials (481& 447 participants) in favour of surgery and adjunctive hormone therapy. On the other hand another 2 trials (280 participants) showed sig- nificant benefit in pelvic pain score (Std. Mean difference-0.80, 95%Cl -1.05 to -0.55) but con- siderable heterogeneity (I²= 96%) was observed. Conclusion: Women who received Post-surgical hormone therapy in the treatment of sympto- matic endometriosis had no advantages in respect of endometriosis and pelvic pain recurrence in compared with surgery alone.
RESUMO
After the necessity of using medical news information and the advances in its automatic indexing were analyzed, a novel automatic controlled indexing method of medical news text was put forward. The method intro-duced translated MeSH vocabulary as the main indexing words, merging Chinese commonly used word segmentation dictionary, then calculated word frequency for document text which added split token and sorted it, choose top 5 high-frequency words in MeSH vocabulary indexed document after deleting high-frequency words not in MeSH vo-cabulary.
RESUMO
OBJECTIVE: Indexing medical documents is important to retrieve medical information efficiently, but it is labor intensive and an annoying task for indexers or authors. This paper presents that whether an automatic indexing program can help the human task for Korean medical keyword indexing. METHODS: We developed an automatic indexing program using Korean Medical Subject Heading(K-MeSH) and evaluated the performance as compared with technical indexers and authors. RESULTS: Experimental result was that the current program's performance was much lower than technical indexers', but it was same as the authors' performance. CONCLUSION: The result showed that it is very affirmative to develop the automatic indexing program to help authors at least, and to help technical indexers with improving the program by enriching K-MeSH and utilizing K-MeSH structure.
