RESUMO
Objective To explore the hotspots and developing direction of splenic surgery in China.Methods The biliometric analysis was adopted.Database including Chinese Database of Literature on Biomedicine were searched with “脾,外科,移植”.The time for retrieving was from January 1984 to December 2013.Chinese articles on splenic surgery which were published by academic journals were retrieved,and data were analyzed and evaluated by 2 independent researchers,including published year,distribution of journals,key words,authors and publication type.The P-value was calculated according to P =2Ln(eE × Y),and Euler's number =0.577 2 and Y was maximum amount of published articles in each journal.Results (1) Published year:1 977 articles were retrieved.There were 168 articles from 1984 to 1993,and number of articles in every year was less than 30.There were 562 articles from 1994 to 2003 and increasing number of articles in every year,with a maximum number of 88.There were 1 247 articles from 2004 to 2013,and average number of articles in every year was 125,with a maximum number of 165 in 2009.(2) Distribution of journals:all the articles have been published in 489 journals,including 9 surgical journals in the core journal such as Chinese Journal of Hepatobiliary Surgery and 7 journals from Chinese Science Citation Database.The maximum number of published articles of each journal was 54,and literature number in the core journals P≈9.(3) Distribution of key words:occurrence frequencies of “脾破裂”and“脾切除术”were very high in 3 periods (from 1984 to 1993,from 1994 to 2003,from 2004 to 2013) and percentages of occurrence frequencies were respectively 9.524％,24.911％,51.163％ and 12.500％,19.217％,38.813％,showing an increasing trend.Occurrence frequencies of“回顾性研究”“手术后期间”“胰腺切除术”and“脾动脉”reached the top 20 of key words from 1994 to 2003 and then continued to increase from 2004 to 2013,and occurrence frequency of“回顾性研究”was significantly increased witha growth rate of 23.742％.The percentages of occurrence frequencies of“回顾性研究”“手术后期间”“胰腺切除术”and“脾动脉”were respectively 3.203％,8.185％,4.448％,3.559％ from 1994 to 2003 and 26.945％,16.279％,7.939％,6.496％ from 2004 to 2013.“创伤和损伤”and“腹腔镜”first appeared on the top 20 of key words from 2004 to 2013,with percentages of occurrence frequencies of 15.958％ and 11.307％.Occurrence frequencies of“胰腺”and“肝”were gradually increased in 3 periods,with the percentages of 2.976％,3.915％,10.906％ and l.786％,4.804％,6.496％.The percentage of occurrence frequency of“移植,自体”in 3 periods was respectively 15.476％,20.107％,8.821％.Conclusions The Chinese articles of splenic surgery are rising obviously in the past 30 years.The splenic injury and splenectomy have always been research hotspots in splenic surgery.The preservation of spleen function and minimal invasive surgery are the developing direction of splenic surgery.
RESUMO
The aim of this study is to determine the geographic origin and level of evidence (LE) of articles published in Chilean dental journals during 2012. The target population for the bibliometric study was articles published in exclusively-scientific Chilean dental journals. These variables were analyzed: journal, area, language, country, region, design, scenario, and LE. A total of 120 articles were published in four journals: International Journal of Odontostomatology (IJOS=59), Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral (PIRO=28), Journal of Oral Research (JOR=18), and Revista Dental de Chile (RDC=15). From the total, 80.83 percent were published in Spanish and 70 percent had a Chilean affiliation. Most publications corresponded to areas of pathology (21) others (20) and prosthodontics (20). None of the articles was Level 1 Evidence, 6.49 percent was 2b, 14.29 percent was 2c, 63.64 percent was 4, and 15.58 percent was 5. Chilean dental journals mainly publish articles of domestic origin and low LE.
El objetivo de esta investigación es determinar el origen y nivel de evidencia (NE) de los artículos publicados en las revistas odontológicas chilenas durante el año 2012. Estudio bibliométrico, la población objetivo fueron todos los artículos publicados en revistas dentales chilenas de orientación exclusivamente científica. Se analizaron variables: Revista, Área, Idioma, País, Región, Diseño, Escenario y NE. Se hallaron 120 artículos publicados en cuatro revistas: International Journal of Odontostomatology (IJOS = 59), Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral (PIRO = 28), Journal of Oral Research (JOR = 18) y Revista Dental de Chile (RDC = 15). El 80.83 por ciento de los artículos fue publicado en español y el 70 por ciento corresponden a autores chilenos. La mayor cantidad de publicaciones correspondieron a las áreas de Patología (21), Otra (20) y Prostodoncia (20). No se hallaron artículos de NE 1, 6.49 por ciento fue 2b, 14.29 por ciento fue 2c, 63,64 por ciento fue 4 y 15.58 por ciento fue 5. Las revistas odontológicas chilenas publican principalmente artículos de origen nacional y con un bajo NE.
