The hospital improved its pre-examination quality of laboratory medicine by means of setting up pre-examination quality management committee, full-course supervision of pre-examination process, and clarified responsibility system. Informationization means play multiple roles for the pre-examination quality, including full-course management, early warning and interception of unqualified sample. The coordinated application of multi-departments, multi-links and multi-measures can improve the pre-examination quality of laboratory medicine and ensure the quality of test results and the medical safety of patients.

Objective To determine the viability of Schistosoma japonicum cercariae by staining. Methods Schistosoma japonicum cercariae were stained by 0.4%trypan blue 0.5%methylene blue?eosin?borax M.E.B 0.5%eosin 0.5%methy?lene blue and 0.05% neutral red respectively for 5 min then they were observed under a stereoscopic microscope. Results The dead cercariae were stained in the trypan blue M.E.B eosin and neutral red but unstained in the methylene blue. The vi?tal cercariae were unstained in all the five kinds of dyes. Conclusion The staining methods by using 0.4% trypan blue 0.5%M.E.B 0.5%eosin and 0.05%neutral red can be used to determine the viability of S. japonicum cercariae.

Objective To investigate types of knee joint injury among island garrison force and the effect of arthroscopy,and also to recommend related preventive measures.Methods Forty-two cases of knee joint injury were collected from the medical data registered from March,2012 to April,2013,and diagnosis and treatment were performed by arthroscopy.Results Of the 42 cases of knee joint injury,there were 31 cases of anterior cruciate ligament injury,14 cases of internal meniscus injury combined with external meniscus injury,2 cases of simple meniscus injury,1 case of external discoid cartilage injury,2 cases of chondromalacia patellae,3 cases of traumatic synovitis,1 case of posterior cruciate ligament injury,and 1 case of traumatic knee joint arthritis.Following treatment by arthroscopy,all the patients returned to duty.Conclusion In the knee joint injury that occurred among island garrison military per-sonnel,the highest incidence was anterior cruciate ligament injury,with complete rupture of ligament in most cases.There was a rela-tively high rate of misdiagnosis and treatment delay.For this reason,attention should be paid to knee joint injury occurred among mili-tary personnel,and early arthroscopy should be performed as early as possible,so as to improve cure rate.
