OBJECTIVETo explore breeding method and breed new varieties of Erigeron breviscapus.

METHODSuperior individual were selected from natural outcrossing population of E. breviscapus, lines and strains were established and selected and compared.

RESULTThe scutellarin contents of two E. breviscapus strains of 2003-15 and 2003-6 through line breeding were 3.21% and 3.01%, respectively, and increased 15.77% and 23.46% comparing with the control strain (QS-1), respectively, the yield increased 20.37% and 17.59%, scutellarin yield per hectare enhanced 39.31% and 44.82%.

CONCLUSIONNew varieties of E. breviscapus can be bred through lines breeding.

The dissemination of culture requires carriers.The construction of hospital characteristic culture and hospital brand culture that highlights hospital characteristics needs to be recognized by medical staff and patients.A good hospital culture is one of the important factors to enhance hospital competitiveness,and can also enhance the hospital's reputation among the pub-lic.As a very common way of information circulation in China,self media and integrated media are rapidly developing and inno-vating in the field of healthcare.Hospitals should actively build their own"micro"cultural platforms.Using self media platforms to tell micro stories,popularize micro knowledge,shoot micro movies,publish micro books,hold micro forums,and micro mu-sic,to enrich patients'cultural lives and create an exclusive hospital culture.
