Objective To evaluate the effects of mindfulness-based stress reduction(MBSR) on fatigue and sleep quality for breast cancer patients undergoing chemotherapy. Methods Totally 96 patients with breast cancer under-going chemotherapy were assigned into the intervention group and the control group with 48 cases in each group from a tertiary hospital in Zhengzhou city. Both groups received routine care,and the intervention group also received 8 weeks of MBSR. The Revised Piper Fatigue Scale(PFS-R) and Pittsburgh Sleep Quality Index(PSQI) were used to assess fatigue and sleep quality of two groups during chemotherapy before the intervention(T1),after the interven-tion(T2) and 3 months after the intervention (T3). Results There were significant differences in sensory,behav-ioral,emotional and total fatigue scores between the two groups(P<0.05);the time effect on fatigue of the various dimensions scores and total fatigue scores was significant(P<0.05);sensory aspects,emotional aspects,behavioral aspects,and total fatigue scores were interfered between intervention and time factors(P<0.05). There were signifi-cant differences in sleep quality,fall sleep time,sleep time,sleep efficiency and sleep scores between the two groups(P<0.05);the time effect on sleep quality,sleep time, fall sleep time was significant(P<0.05);there were interac-tion effects between intervention and time on sleep quality,sleep time,sleep disturbance and sleep total score(P<0.05). Conclusion MBSR can effectively relieve fatigue and improve sleep quality for breast cancer patients undergoing chemotherapy.

Coronary heart disease (CHD) not only threatens public health severely, but also brings a heavy economic burden to our society and country. This paper tries to start with the risk assessment tool, and reviews the risk assessment tool for CHD patients as well as its application value, existing problems and development prospects,so as to promote the secondary prevention and standardized care for CHD patients.
