RESUMO
Chronic heart failure is a major public health problem threatening people’s life. As an important measure of non-drug treatment and secondary prevention, cardiac rehabilitation can improve the quality of life and reduce readmission rate of chronic heart failure patients. Training exercises are important elements in cardiac rehabilitation and play a key role in cardiac rehabilitation of patients with chronic heart failure. Moreover, tele-monitoring exercise training has been widely used in cardiac rehabilitation of patients with chronic heart failure overseas. With the tremendous development of “internet ＋ healthcare”, it is worth thinking about how to carry out tele-monitoring exercise training of chronic heart failure. In this review, we introduced the progress of tele-monitoring exercise training in patients with chronic heart failure.
RESUMO
Objective To compare the compression properties of articular cartilage and polyinyl alcohol hydro-gel(PVA-H)as artificial carlage.Method Unconfined compression tests were conducted on articular card-lage and PVA-H,including stress-strain tests,creep tests and stress relaxation tests.The stress-strain rela-tionship of articular cartilage and PVA-H were measured.Result The compression modulus of articular card-lage was higher than that of PVA hydrogel.The average compression modulus of articular cartilage and PVA hydrogel was(3.6492±0.6199)Mpa and(1.5951±0.1469)Mpa,respectively.Condusions The experimental results revealed the differences existed between articular cartilage and PVA-H and this would be useful to fur-ther improve the mechanical properties of artificial cartilage.
