Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

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.

BACKGROUND:Periosteal osteoblasts possess strong reproductive activity,as well as osteoblastic differentiation potential,which is an ideal seed cell if can shorten the culture time.OBJECTIVE:Modified enzymatic digestion was used to culture rabbits'osteoblasts.and to study the adherence and proliferation of osteoblasts on the sudace of sandblasting titanium.MEITHODS:Periostea were harvested from the theanteromedial surface of the proximal tibia of male,Japanese white rabbits,and cultured as follow:①Routine method:Digested with 0.25%trypsinase at 37 ℃ for 30 minutes,followed by digestion with 0.1%type I collagenase at 37 ℃ for 30 minutes,vibration.removed trypsinase and dried.After 2 hours,DMEM containing 15% fetal bovine serums were added.②Modified method:30 minutes culture of type I collagenase was prolonged to 1 hour.The osteoblasts were identified by alkaline phosphatase staining and calcium node staining.The adherence and proliferation of osteoblasts cultured on sandblasting surface were measured by scanning electron microscopy and MTT.RESULTS AND CONCLUSION:Five days after culture.the periosteal steoblasts crawled out from tissues,gathered as monolayer with tdangle or polygon at after 25 days of modified culture.After 1 month of culture,superposition growth of calcium nodus appeared.The cultured cells possessed the morphological characteristic and biological behavior of osteoblasts.which were positive to alkaline phosphorase and calcium node staining.The time of cells cultured with routine method covered flask delayed 12 days than modified method.The osteoblasts were inseted into sandblasting titatium with pseudopodium.However,the adherence and proliferation of osteoblasts cultured on sandblasting surface had no obviously difference between two culture methods.The results suggested that modified enzymatic digestion can sho～en the culture time without effect on adherence and proliferation of osteoblasts.

Objective To investigate the mechanism by which electro-acupuncture (EA) promotes revascularization in the brain after focal cerebral ischemia and reperfusion.Methods The Sprague-Dawley rat model of focal cerebral ischemia was made by filament occlusion. The rats were randomly divided into a control group, a model group, and an EA group. The model and EA groups were each divided into 5 subgroups receiving reperfusion 1, 3,7, 14 or 21 days after ischemia. EA was given at the bilateral Hegn point (LI 4) in the EA group. The expression of stromal cell-derived factor-1α(SDF-1α) mRNA was detected using a RT-PCR in the 3, 7 and 14 day subgroups.The immunohistochemical method was employed to detect the expression of SDF-1α protein. Results Compared with the control group, expression of SDF-1α protein increased significantly in the model and EA groups. Compared with the model group, the expression of SDF-1α mRNA increased significantly in the 3, 7 and 14 day subgroups.SDF-1α protein expression and microvessel count increased slightly but not significantly in the 1d subgroup, but the increases were significant in the 3, 7, 14 and 21 day subgroups.Conclusions EA may promote angiogenesis in an ischemic area of the cortex by increasing the expression of SDF-1αmRNA and its protein after focal cerebral ischemia and reperfusion.
