Objective To report and analyze the changes of bacterial species and resistance to antibiotics in the burn center from 1993 to 2007. Methods Bacterial identification and susceptibility test were performed by applying VITEK-AMS system. Results A total of 4 762 strains were isolated,including 60 species of 21 genera. Pseudomonas aeruginoasa (PA) was the most common organism (36. 79%), and its isolating rate was 36. 79%; in 2006, the highest isolating rate of PA was 51.6%.The isolating rate of Staphylococcus aureus was 14.09 %, next to that of PA; followed by Enterococci faecalis, Acinetobacter, Escherichia coli, Enterococci faecium, Enterobaeter cloacae and Staphylococ-cus epidermidis, and the 8 kinds of germs shared 78. 12% of bacterial isolates (3 746/4 762). The an-tibiotic resistance rate of Pseudomonas aeruginosa was increasing year by year; it was vitally resistant to the third generation eephalosporins and imipenem. Conchtsion The predominant species of bacteria from burn center is Pseudomonas aeruginosa, and RA isolates are multi-resistant to antibiotics. The i-solating rates of Enterococeus faeealis and Acinetobacter are increasing. This implied the importance of rational and correct use of antibiotics about control of burn infections as well as avoidance of abusage of broad-spectrum antibiotics.

Objective To summarize the progress of injury cohort studies over the world. Methods Relevant information of injury cohort publications published before December 2017 were retrieved from PubMed, WanFang and China National Knowledge Infrastructure (CNKI) databases, consisting of the starting year, category of injury, study population, sample size, countries, follow?up duration, main exposure variables, outcome variables and method of data collection, and statistical methods. Results A total of 295 studies were included in the analysis. The overall number of injury cohort studies increased with a peak in 2000, and then decreased. The top three countries that most frequently published cohort studies were the United States (52), Sweden (46) and the United Kingdom (37). A total of 29 published injury cohorts were identified in China, about 3, 23 and 3 cohort studies from the mainland of China, Taiwan Province, and Hong Kong Specific Administrative Region, respectively. The majority of cohort studies involved a single injury cause (93.6%); the most common injury causes included suicide/self?harm (46.1%), falls (17.3%) and road traffic injuries (14.6%). For the published cohort studies, exposure variables and outcome events varied with injury causes, primarily being collected through data registration system, national survey data, questionnaire survey, telephone interviews, and other means. Conclusion A number of injury cohorts have been established worldwide, and few in the mainland of China. The existed cohort studies could offer important references for the design of large?scale, multi?center and high?quality injury cohort in China in the future.
