title: [Analysis and evaluation of the articles concerning animal experiments published in Chinese Journal of Burns during 2000 to 2004].
abstract: OBJECTIVE
  To investigate the current situation of animal experiments by analysis and evaluation of relevant articles published in the Chinese Journal of Burns during 2000 to 2004.
  
  
  METHODS
  All articles concerning the results of animal experiments related to the treatment and medical studies in the past 5 years were analysed according to the international standard , especially in serval aspects, such as sample size, randomization method, sample choice, comparison measure, baseline comparability, estimate index, statistics method, and so oN.
  
  
  RESULTS
  During 2000 to 2004, totally 1 116 papers were published in the journal, among them 81 papers were (accounted for 7.3% ) of all articles were reports of treatment related experiments. Out of 81 papers, in 69 experiments ( accounted for 85. 2% ) there was randomized control group, and the main problems lay in calculation of the number of samples, the application of randomization method, and analysis of statistics.
  
  
  CONCLUSIONS
  Application of the randomized control modality in animal experiment is popular in our country, but the design of some studies is not so rigorous. Therefore, we should improve the design of every research project before the experiment is carried out.
