RESUMO
Objective:Using the Smith Model of policy implementation, the paper analyses how an adverse e-vent,the"Si-xian County Vaccine Incident",caused the termination of organized vaccination in universities L city. Methods:Case study, in-depth interviews among 15 key insiders, and 5 focus-group interviews among college students. All interviews transcribed,coded and analyzed. Results:There are no clear policy targets nor specific im-plementation standards for college students' vaccination. The target group (college students) holds a low level of awareness of vaccination. Implementation departments are sensitive to any risks due to the prevalent stability-oriented social environment,and have limited space for action when facing emergencies. Conclusion:In the stability-oriented social environment,the Si-xian County Vaccine Incident amplified the risks and limited the space of vaccination poli-cy implementation. In the absence of policy goals for college student vaccination,it was safer to terminate organized vaccination programs,which had a negative impact on university vaccination. The government should lay out specific policy goals for vaccination,and broaden the possible implementation space,as well as establish mechanisms for at-tenuating the risks of vaccination.
RESUMO
OBJECTIVE: To study chemical constituents from rhizome of Daphne papyracea var. crassiuscula. METHOD: Ethyl acetate fraction of 75% ethanol extracts from rhizome of D. papyracea var. crassiuscula, and its strucutre was identified by spectral method. RESULT: Nine compounds were separated and identified as daphneticin (1), daphnetin (2), hydrangetin (3), daphnoretin (4), 1-4'-hydroxyphenyl-5-phenyl-2 (E)-en-1-pentanone (5), daphneolon (6), 3beta-O-acetyl-olean-12-en (7), and (+)-usnic acid (8). CONCLUSION: Compounds 1-8 were separated from D. papyracea var. crassiuscula for the first time. Compound 8 was separated from the genus for first time.
