ABSTRACT
Mesoporous silica nanoparticles as drug carrier have become the new hot point in the field of biomedical application in recent years. This review focuses on the more recent developments and achievements on experimental design aspect of mesoporous silica nanoparticles with cancer diagnosis and therapy. The key advances of functionalization strategies of mesoporous silica nanoparticles with controlled release, tumor targeting and overcoming multidrug resistance are discussed in particular. Mesoporous silica nanoparticles as unique delivery systems have the potential to provide significantly a sound platform for cancer theranostic application.
ABSTRACT
By analyzing the questionnaire survey of consciousness of rights protection and status quo of rights and interests among medical staff in three 3rd degree and A grade hospitals located in northwest Hubei province,this paper concludes that medical staff there have a generally strong consciousness of rights,while their rights and interests are not well protected by society and hospitals,especially certain aspects including personal security,occupational health,working hours,legal vacation,and the rights to be involved in hospital management.It is suggested that legal rights and interests of medical staff should be improved through legislation,social support,and the direction function of public opinions.
