Objective To investigate effects of Taikong Yangxin Prescription on left ventricular pump and contract function in rat after tail suspension.Methods Twenty four male Sprague-Dawley(SD)rats were randomly and divided into three groups:(A)normal control group,(B)tail-suspension group and(C)Chinese herb compound group(taking Taikong Yangxin Prescription and tail suspension).The left ventricular functions in rats were examined by echocardiography separately after 7 d and 28 d tail-suspension.Results After 28 d of tail-suspension,as compared with the tail-suspension group,LVDD in Chinese herb compound group increased significantly(P

Exercise fatigue is a physiological phenomenon not only for athletes, but also for astronauts. It is vital for athletes with hard training and astronauts with the heavy exercises for the mission in manned space flight to know how to solve the exercise fatigue. This article reviewed current commonly used TCM protective measures against fatigue.

Objective To observe and analyze the application of Pareto law and PDCA principle in ICU nursing teaching. Methods Totally 133 nursing interns in ICU from October 2015 to October 2016 were chosen as the control group adopting the routine nursing teaching method; 137 nursing interns from November 2016 to November 2017 were selected as the experimental group for whom Pareto law and PDCA principle were applied in ICU nursing teaching. The post-teaching theory, skill test scores, quality of nursing documents and satisfaction with teaching were compared between the two groups. Results As for the doctor's order list, body temperature list, nursing record sheet, repairable rate of nursing document defect, the test group accounted for 0.73％ (1/137), 0, 0.73％ (1/137) and 1.46％ (2/137) respectively, while those of the control group were respectively, 5.26％ (7/133), 4.51％ (6/13), 8.27％ (11/13), and 18.05％(24/133). The difference between the two groups was statistically significant (χ2=4.8235-39.3526, P<0.05 or <0.01)). In the experimental group, the scores of theoretical knowledge, professional operation, patient management and work attitude were as follows:(93.5±1.4), (94.9±1.1), (89.2±3.3) and (91.5±2.6);those of the control group were respectively (93.5 ± 1.4), (94.9 ± 1.1), (89.2 ± 3.3) and (91.5 ± 2.6). The difference was statistically significant (t=21.3228-26.9353, P<0.01). The satisfaction rate of the test group was 100.00％ (137/137), and that of the control group was 69.17％ (92/133). The difference was statistically significant (χ2=41.3671, P<0.01). Conclusion In ICU nursing teaching, the application of Pareto law and PDCA principle can effectively improve the test scores of theory and skill operation after nursing teaching, enhance the quality of nursing documents, improve the interest of nursing interns in learning, and raise the teaching satisfaction rate. Thus, the effect is ideal.
