The influence of policy advocacy and education on medical staff's adaptation to diagnosis related groups payment reform in China: an analysis of the mediating effect of policy cognition.

Introduction: In recent years, China has been carrying out the Diagnosis Related Groups (DRGs) payment reform, which has an impact not only on payment methods and medical expenses, but also on the behaviors of medical staff. Some of these behaviors are unexpected by policymakers, such as turning away critically ill patients, disaggregating hospitalization costs, setting up disease groups with higher points, and so on. This phenomenon attracted the attention of some scholars, who put forward a few positive intervention measures, mainly including policy advocacy and system improvement.

[Distribution patterns of woody plant diversity in stream riparian forests along an altitudinal gradient in Changbai Mountains].

By setting up sample transects and using alpha and beta diversity indices, this paper studied the woody plant diversity and its responses to cutting in the stream riparian primeval and secondary forests along an altitudinal gradient in Changbai Mountains. The results showed that all of the primeval forest communities distributed at different altitudes were composed of 11-13 tree species, but the importance of these tree species varied with altitude. Conifer species gradually took the place of broad-leaved tree species along the altitudinal gradient.
