AIM: To explore the significance of platelet activation, fibrinolytic activity and the changes of vasoactive mediators in acute myocardial infarction in rabbits and the intervention of amiodarone and metoprolol. METHODS: Fifty New Zealand white rabbits were randomly assigned to five groups, ten for each. Group Ⅰ: sham group, group Ⅱ: acute myocardial infarction(AMI) group, group Ⅲ: AMI and lidocaine group, group Ⅳ: AMI and amiodarone group, group Ⅴ: AMI and metoprolol group.The middle point of left ventricular coronary artery was ligated (groupⅡ,Ⅲ, Ⅳ and Ⅴ ) or a sham ligation(group Ⅰ). Four hours later, blood was collected for measuring plasma concentration of TXB 2, 6-Keto-PGF 1?, ET, NO, plasma activity of t-Pa and PAI.After that, the heart was taken out to evaluate the infarction size(IS). RESULTS: Plasma concentration of TXB 2, ET, NO and plasma activity of PAI were significantly higher in groupⅡ,Ⅲ, Ⅳ and Ⅴ than those in group Ⅰ(P0.05).Compared to group Ⅱ, plasma concentration of ET, NO and PAI activity were significantly decresed (P

The aim of this review is to realize the significance of physical activity for colorectal cancer survivors, collect the common tools to assess colorectal cancer patients' physical activity, understand the current status and its influencing factors of colorectal cancer patients' physical activity as a reference to Chinese relevant research and provide a basis for carrying out medical or nursing intervention.

Objective To analyze and provide reference for developing clinical practice guidelines of ostomy care suitable for the domestic health care settings. Methods Content analysis method was used to analyze clinical practice guidelines searched from the Internet. Results A total of 13 clinical practice guidelines were included. All the guidelines were published between 2005 to 2016 without update. Four of them were evidence-based guidelines, the rest were not. A total of 21 items were identified as being related to ostomy care. Conclusions Although the existing clinical practical guidelines are instrumental to guiding clinical ostomy care practice, most of them were not evidence-based guidelines without high methodological quality. Meanwhile, some guidelines lack specific and updating recommendations for ostomy care, which may cause problems in ostomy care practice. What′s more, some recommendations may not suit for China because they were made in the foreign circumstance. Researchers and clinical nurses should develop local practice guidelines of ostomy care with consideration of the actual medical conditions in China and the best evidence.
