To investigate the infection status of pigs with Cryptosporidium parvum, 589 fecal samples were collected from pigs raised at farm in Chungcheongbuk-do and Chungcheongnam-do. Of the 589 pig fecal samples, 62 (10.5%) were positive for C. parvum. The area showing the highest positive rate was Dangjin-gun, Chungcheongnam-do (14.0%), and the lowest (0%) Salmi-myon, Chungcheongbuk-do. The positive rate of C. parvum in Judok-eup increased from 12.7% in the winter to 22.1% in the summer. The results of this study suggest that the pigs may be a source of human C. parvum infection.

The mesenchymal stem cell ( MSC ) is an important component of the hematopoietic microenvironment .In the process of stem cell transplantation (SCT), MSC can restore the hematopoietic microenvironment , improve the capacity of hematopoiet-ic reconstitution, reduce the incidence of graft versus host disease (GVHD).MSC has been widely used in hematopoietic stem cell transplantation, immune therapy, tissue engineering and many other fields .The distribution and colonization of MSC in vivo directly af-fect the effectiveness of transplantation .Improving the homing and engraftment of MSC may obtain a better therapeutic effect .Further research on the mechanism and influential factors of MSC homing may lead to the development of therapies and promote clinical applica -tions of MSC.This paper reviews the recent progress in homing mechanism of MSC .

Objective To establish the nursing care for the patients with pulse steroid therapy, and to investigate its effect. Methods 78 patients who accepted pulse steroid therapy in the past 4 years were analyzed retrospectively, in which, 42 within past 2 years （2008 and 2007) were as pulse steroid nursing care group, and other 36 patients before 2 years (2007 and 2006) were as routine nursing care group. Results 3 weeks after the pulse steroid therapy, in pulse steroid nursing care group, proximal muscle weakness were found in 8 patents, insomnia in 18 patients; while in routine nursing care groups, proximal muscle weakness were found in 16 patents, and insomnia in 25 patients（P<0.05）. Conclusion Pulse steroid nursing care can reduce the incidence of muscle weakness and insomnia after pulse steroid therapy significantly.

ObjectiveTo explore the PBL mode in training students' ability,improve the quality of teaching effect,in the teaching of Clinical therapeutic ultrasound and the teaching method based on problems with discussion method.MethodsTo 31 subjects of study who were randomly divided into five groups,each 6 people,a PBL teaching mode was used for 12 periods by proposing and study,group discussion,the whole class exchange and commenting on summary.ResultsThe survey shows that 93.6％ students think the teachers' design has gained their ends,71％ students are impressed by the knowlege and 96.8％ of the students show the good learning attitude,64.5％ of the students raised their interest in learning,which shows teaching results are effective.ConclusionPBL mode is superior to LBL teaching mode in training students' ability,improving the quality of teaching effect.
