OBJECTIVE: To explore the effect of rehabilitation training on restenosis following stent implantation in patients with coronary atherosclerotic heart disease. METHODS: A computer-based online search of VIP database was performed to search articles regarding restenosis following stent implantation and rehabilitation treatment for patients with coronary atherosclerotic heart disease, published between January 2000 and October 2009, with key words "coronary artery, stent implantation, intracoronary restenosis, rehabilitation exercise". The data were collected, and the references of each article were reviewed. A total of 20 articles were included. Results: Intracoronary stent has become an effective treatment for coronary atherosclerotic heart disease, and intracoronary restenosis has been focused in clinical studies. Prophase treatment following stent implantation is very important for coronary atherosclerotic heart disease. Rehabilitation exercise in combination with antiplatelet anticoagulation and lipid treatment can reconstruct coronary arterial blood transport and significantly reduce incidence of restenosis and thrombus. Conclusion: Regular rehabilitation exercise following stent implantation can ameliorate degree of vascular restenosis. Source

OBJECTIVE: To explore the dynamic features of knee flexion movement to provide relative movement and stress distribution for studies on artificial knee joint bio-tribology. METHODS: A computer-based online search of CNKI was performed for articles related to artificial knee movement and friction published between 1994 and 2009 with key words "knee prosthesis, biomechanics, wearing debris, bionic lubrication". Outdate articles and repetitive studies were excluded, and 22 articles were included. RESULTS: Dynamic finite element models of knee joint including bone and soft tissues following total hip replacement are established. Three dimensional relative movement parameters of knee flexion and extension, as well as contact position and stress of tibial and hip and femoral joints are obtained using finite element analysis. CONCLUSION: Artificial knee joint wearing performance is influenced by many factors. Many studies focus on some factor alone, and mainly describe experimental results, but not further exploration of joint movement and wearing mechanism. Studies of artificial knee joint movement and wearing performance should combine kinematics and mechanics with wearing status for prediction of wearing. Source
