OBJECTIVEThis study was designed to investigate the influence of journals indexed by Science Citation Index (SCI) on Chinese medical journals.

METHODArticles on medicine written by Chinese and the journals that published these articles from 2000 to 2009 were searched using Science Citation Index Expanded (SCI-E) database, and the status and variation tendency of the impact factors (IF) of these journals were analyzed. Data of articles on medicine included Chinese Scientific and Technical Paper and Citations Data (CSTPCD) from 2000 to 2008 were searched (the data of 2009 have not been released). The included articles and the time-dependent changing profile were studied. These outcomes were evaluated as the fixed base relative or link relative when compared with the data of 2000 or those of last year, respectively. Geometric mean was used when mean increase was calculated and IF distribution was described with median.

RESULTTotally 3774 articles from China were published by journals indexed by SCI-E in 2000, and the number of articles published by Chinese authors increased every year. In 2008, 16 714 articles were indexed by SCI-E, 442.87% higher than those of 2000. The increment was 161.54% higher than that of articles published in the journals indexed by CSTPCD (281.33%) during the same period. From 2000 to 2009, the geometric mean of increase in the number of published articles from China in journals indexed by SCI-E was 20.87% but it was 18.21% in CSTPCD. From 2000 to 2009, the median of IF of SCI-E indexed journals that published Chinese medical articles was 1.866, 2.073, 2.390, 2.702, 2.409, 2.496, 2.380, 2.218, 2.280 and 2.331, respectively, and they did not increase or even decreased.

CONCLUSIONThe number of the articles indexed by SCI-E increased year by year, much faster than that of CSTPCD. However, it does not necessarily mean the increase in impact.

Providing adequate and balanced nutrition for preterm infants,especially extremely/very preterm infants,is the material basis for promoting their normal growth and development and improving long-term prognosis.Enteral nutrition is the best way to feed preterm infants.Previous systematic reviews have shown that using evidence-based standardized feeding management strategies can effectively promote the establishment of full enteral feeding,reduce the duration of parenteral nutrition,improve the nutritional outcomes of preterm infants,and not increase the risk of necrotizing enterocolitis or death.Based on relevant research in China and overseas,the consensus working group has developed 20 recommendations in 5 aspects including the goal of enteral nutrition,transitioning to enteral nutrition,stable growth period enteral nutrition,supplementation of special nutrients,and monitoring of enteral nutrition for preterm infants,using the Grading of Recommendations Assessment,Development and Evaluation.The aim is to provide recommendations for healthcare professionals involved in the management of enteral nutrition for preterm infants,in order to improve the clinical outcomes of preterm infants.
