Objective To summarize the experience of medical rescue conducted in Aba prefecture after the Wenchuan earthquake in order to provide information for similar tasks in seismo-active regions. Methods We participated and witnessed the whole process of medical rescue through 100 days after the quake. Data regarding the medical rescue work, work mode, performance and problems were collected and analyzed. Results Twelve counties out of the 13 counties in Aba prefecture were affected by the earthquake, including 2 most-hit counties and 5 most-hit areas. A total of 20 233 people died and 7 873 disappeared. Aba Prefectural Headquarters for Earthquake Resistance and Disaster Relief was set up and medical rescue teams were dispatched to the disaster area immediately after the quake: ① From May 12 to May 15 2008, 20 local medical teams comprising 138 healthcare professionals and 14 teams involving 428 professionals from other regions arrived at the most-hit areas. Through 7 days after the quake, medical treatment was provided for 6 285 patient-times. ② A total of 1 444 healthcare professionals participated in the medical rescue work. Through August 20, 355 579 outpatients and 7 028 inpatients were treated in the prefectural medical institutions and on-site medical centers. Of those, 6 726 were discharged, 604 were severely wounded, 20 died and 456 were transferred to other regions for further treatment. 2 703 operations were performed for the wounded and psychological treatment was provided for 4 630 person-times. Conclusion The medical rescue work in Aba prefecture after the Wenchuan earthquake was effective and efficient. Management of human resources and medical devices should be strengthened to enhance the ability of emergency response.

We summarized and analyzed the researches of the workshop on Evidence-Based Medicine for Medical Editors which was recently held concerning its teachers, training method, trainee distribution and recent progress. We hope to provide a new approach to improving the level of medical editors and clinical trials.
Objective To assess the effect of a new educational model for evidence-based medicine (EBM), which is called "2+N" model with the main characteristic of classroom teaching plus volunteer practice. Methods Questionnaire survey was conducted to collect data. Results There were averagely 39 volunteers participated in this activity per year, with an increasing trend. Most of them were sophomore and junior undergraduates from different specialties in medical filed. All participates acquired a better understanding of EBM knowledge; more than 60% of them could handle data searching, collecting and assessing by themselves in the end of the activity. Conclusion Our five years’ experience of EBM education practice for medical students suggested that the new educational model has a promising future.
Objective To investigate present status of health care in peri-brain-death and analyze its effectiveness and health economic characteristics. Method Retrospective analysis of case series was conducted and a total of 940 patients from surgical intensive care unit (SICU) were reviewed on treatment and part of direct medical expenditure. The patients admitted from Jun. 1999 to Dec. 2000 and Nov. 2001 to Jun. 2002 were included in this study. Data were processed by SPSS 10.0. Results Patients were included if they had two of the three symptoms for at least one hour: deep coma, pupillar light reflex disappear, and no autonomic respiratory. Ultimately 115 patients were included, with a total cost of ￥2 515.9 per day for each case, whereas mortality was 99.10%. Mortality increased with the state of peri-brain-death prolonged. Eighty percent of patients included were dead within 72 hours after admission. Conclusions Attempts to resuscitate patients of peri-brain-death have been the most widely applied in China, however, it resulted in great unnecessary consumption of health resources. It is of great importance to promote legislation of brain death in China.
Objective To compare articles published in global primary journals titled “evidence-based” via bibliometric analysis in order to provide suggestion for evidence-based research and development of related journals. Methods We searched electronic databases to retrieve global primary journals titled “evidence-based”, and collected their impact factors, article click, download and citation frequency through the journal’s website and related citation databases. Results Three English and 4 Chinese primary journals titled “evidence-based” met the inclusion criteria. (1) Citation frequency: Evidence-Based Complementary amp; Alternative Medicine and Worldviews on Evidence-Based Nursing were indexed by SCI with impact factor over 1 (5th and 13th in relevant subject category), and their immediacy index was about 7 times as much as that of Chinese journals (0.2 vs 0.03). Chinese Journal of Evidence-Based Pediatrics (CJEBP) had the highest impact factor among 4 Chinese journals (0.946, 23rd in the relevant subject category), while Chinese Journal of Evidence-Based Medicine had the highest immediacy index with 0.07; (2) Download frequency: Journal of Evidencebased Medicine (JEBM) had the highest download frequency per article in database (72 vs 23), but the website download frequencies per article of CJEBM and CJEBP were about 5 to 6 times as much as that of database; (3) Number of articles published: Two English journals published the fewest articles but with the highest impact factors. Chinese Journal of Evidence-Based Medicine had the 2nd highest impact factor although published the most articles, as well as the highest download frequency and immediacy index among the 4 Chinese journals. It suggested that there was no direct relationship between the number of the published articles and the impact factor of a journal. Conclusion The impact of English journals is better than that of Chinese journals. CJEBM and CJEBP are the top 2 ones among the Chinese journals with open access websites. The selection of articles should be driven by readers’ demand, and the impact of journals could be improved by online publication with open access.
