Objective To study the effect of different treatment methods on seed germination of wild Morinda officinalis How(MOH),which will provide evidence for breeding new cultivars of MOH.Methods We observed the morphological feature,thousand-seed weight and hygroscopicity of wild MOH,and studied the effect of different treatment methods on the germination rate,germination vigor,and germination index of the seeds.Results The thousand-seed weight was 38.03 g and the seed coat had good hygroscopicity.Stripping seed coat,acid etching with sulfuric acid,and the combined treatment of stripping seed coat with exogenous hormones of gibberellin(GA) and 6-benzyladenine(6-BA) had an effect on increasing germination rate,and the germination rate arrived 88.89% after the combined treatment of stripping seed coat with 4 mg/L 6-BA.Conclusion The germination inhibitors containing in the seed coat mainly contribute to the difficulty of the germination of MOH,and the germination inhibitors containing in the seed also have some influences on the germination.

Objective To explore the application effect of the adult education theory in the nursing round. Methods 340 trainee nurses, who were trained at our surgical department between June 2008 and December 2009, were randomly divided into the experimental group(178 cases)and the control group(162cases). The adult education theory was adopted in the experimental group, whereas the traditional education method was used in the control group, a questionnaire was carried out after the nursing visit. Results The experimental group was more satisfied with the round visit than the control group. Conclusions The application of the adult education theory in the round visit is beneficial not only to the students' selection of the topics of nursing visit, but also to the improvement of the students' understanding and communicating capacity, the students' studying interests and the students' creative thinking, finally the degree of satisfaction to the round visit is increased by the adoption of this theory.

Objective:To evaluate the prophylactic application of antibiotics in oral and maxillofacial surgery and to provide a scientific basis for its reasonable use .Methods: The use of prophylactic antibiotics in the oral and maxillofacial surgery was conducted in our hospital from January 2011 to August 2013 based on a retrospective survey , and the conditions and affecting factors were analyzed .Results:The utilization rates of prophylactic antibiotics were respectively 98.9%, 61.8%, and 24.6%, showing a downward trend .But the infection rate of surgical site did not significantly increase , and by Fisher ’ s exact test, the difference was not significant (P>0.05).Surgical site infections (SSI) rates did not rise between using and not using prophylactic antibiotics ( P>0 .05 ) .Conclusion: The use of prophylactic antibiotics is greatly influenced by the policy , and along with the decline in antibiotic usage , SSI have not increased significantly .
