BACKGROUND:Medical stuff have significant impacts on the development of organ donation and transplantation, however, medical students present insufficient knowledge and ambivalent attitude towards organ donation and transplantation. OBJECTIVE:To perform a systemic review on the effectiveness of educational program intervention on medical students’ knowledge and attitudes toward organ donation and transplantation. METHODS:PubMed, WILEY ONLINE LIBRARY, ProQuest Health, Medline, EMbase, CNKI, Wanfang and VIP databases were ful y searched for the published literature of medical students receiving an educational program intervention on organ donation and transplantation. According to the inclusion criteria, randomized control ed trials and quasi-experimental study were evaluated with the standard of Joanna Briggs Institute. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework was used to guide the assessment of the methodological quality of the studies. The outcomes were mainly medical students’ knowledge and attitudes toward organ donation and transplantation.
RESULTS AND CONCLUSION:Eight studies from three countries were summarized. The methods were employed in two studies of randomized control ed trials and quasi-experiment received a high quality rating, five studies received middle quality rating and one study received low quality rating. Educational program increased the knowledge in six studies, and changed the attitudes in six studies. Educational program intervention is a significant strategy to increase medical student’s knowledge about organ donation and transplantation. The majority of involved study are
quasi-experiment study, so more high-quality randomized control ed studies are needed.

Objective To validate the therapeutic effect of acupuncture stage treatment on facial spasm and seek a better method for treating this disease. Method One hundred and forty patients were randomly allocated to stage treatment (50 cases), acupuncture (50 cases) and Western medicine (40 cases) groups. In the stage treatment group, treatment was divided into early, middle and late stages according to the patients’ duration of disease. Each stage provided acupuncture point injection of different medicine plus warm needling. The acupuncture group received conventional acupuncture with 1 hour retention of needles and the Western medicine group, oral administration of carbamazepine tablets, 0.2 g 3 times a day. After the completion of treatment course, a six-month follow-up was performed to determine no relapse or aggravation in the three groups and the therapeutic effects were evaluated using Cohen and Albert spasm grading criteria.Result The complete resolution rate was 56% (28/50) in the stage treatment group, 14.0% (7/50) in the acupuncture group and 20.0% (8/40) in Western medicine group. The complete resolution rate was significantly higher in the stage treatment group than in the acupuncture and Western medicine groups (P<0.05). The total efficacy rate was 100.0% (50/50) in the stage treatment group, 70.0% (35/50) in the acupuncture group and 60.0% (24/40) in the Western medicine group. The total efficacy rate was significantly higher in the stage treatment group than in the acupuncture and Western medicine groups (P<0.05).Conclusion Stage treatment has a marked effect on facial spasm.
