It is recognized that the increasing prevalence of diastolic heart failure in adults has signifi-cantly worsen the quality of life and shorten lifespan.However,the assessment and diagnostic criterion of dias-tolic heart failure in children is controversial.The diagnosis and treatment of DHF are mainly based on small samples of clinical research and clinical experience.There is no effective treatment plan of diastolic heart failure from evidence-based medicine.In this article,we review the progress of diastolic heart failure in children in as-pects of its pathological mechanism,clinical manifestations,function evaluation,diagnosis and treatment.

Objective: To investigate the effect of massive open online course (MOOC) combined with traditional teaching in the teaching of pediatrics. Methods: A total of 153 students in batch 2014 of five-year general medicine in Chongqing Medical University were enrolled as teaching reform group, and 132 students in batch 2013 were enrolled as control group. The teaching reform group adopted the teaching method of MOOC combined with traditional teaching, while the control group adopted traditional teaching alone. The teaching quality was assessed by examination performance and questionnaire survey. Results: The teaching reform group had significantly higher mean examination scores than the control group (P<0.05). The questionnaire survey showed that compared with the control group, the teaching reform group had a better teaching effect and fewer learning questions. Among the 153 students in the teaching reform group, 112(73.2%) approved the fragmented learning mode of MOOC, 79 (51.6%) believed that MOOC could enhance learning efficiency, 103 (67.3%) thought that it could guide self-study and improve learning abilities, 113(73.9%) thought they could manage learning progress by themselves through MOOC, and 99 (64.7%) held the opinion that MOOC could realize the sharing of high-quality educational resources; there were significant differences in these issues between the two groups (P<0.05). Among the 153 students in the teaching reform group, 133 (86.9%) preferred the combined teaching method of MOOC and traditional teaching and were willing to participate in MOOC again. Conclusion MOOC combined with traditional teaching in the teaching of pediatrics can improve teaching quality and is a recommended teaching method at present. It is worthy of further research and perfection.
