Objective To discussed application effect of modified flowchart of preoperational articles in the operating room. Methods A group for the reconstructed flowchart was set up to look into the problems of traditional flowchart for articles preparation and then have the flowchart modified upon the found problems. The duration for article preparation and the flaw rate were compared between pre-and post-modification. Result The duration for preparation after modification was significantly shorter than that before modification and the flaw rate was significantly lower as well (P<0.001). Conclusion The modified flowchart for article preparation in the operation room can reduce the flaw rate and shorten the duration for article preparation, thus ensuring smooth operation.

《Classification of Chinese Library》and《MeSH》 were reconstructed by analyzing the advantages and disadvantages of《Classification of Chinese Library》in semantic tagging of library resources.Ontology of dermatology was constructed and its semantic dictionary was edited on the semantic metadata-aided platform according to the theory of semantic tagging resources with skin diseases as an example in order to achieve semantic tagging resources.
