Accumulating evidence indicates that microRNAs are involved in multiple processes in cancer development and progression. microRNA-26a (miR-26a) has been identified as a tumor suppressor and its downregulation is associated with poor prognosis in several types of human cancer. However, the specific function of miR-26a in osteosarcoma remains unclear. In the(More)
OBJECTIVE Inflammation, which is known to be detrimental to the neurologic outcome during the acute phase after an ischemic stroke, provides a potential target for preventive or therapeutic approach for spinal cord ischemia-reperfusion injury. Tetramethylpyrazine (TMP), a pure compound derived from Ligusticum chuanxiong, is widely used in the treatment of(More)
Researches on the pathology of spinal cord injury (SCI) have been recently focused on oxidative radicals stress and inflammation associated neuronal apoptosis. Resveratrol, a natural phenolic compound, has been extensively studied and shown a wide variety of health beneficial effects, including prevention of cardiovascular diseases and cancer and(More)
Hydroxysafflor yellow A (HSYA) was reported neuroprotective under several ischemic models in vivo. In this study, the direct effect of HSYA against oxygen–glucose deprivation (OGD) inducing acute neuronal injury and the underling mechanisms in vitro were investigated. Four-hour oxygen and glucose deprivation (OGD) followed by 20 h reperfusion (adding back(More)
OBJECTIVE To investigate the implication of morphological changes of the proximal femur in femoral prosthesis selection in total hip replacement for treatment of ankylosing spondylitis (AS). METHODS Twenty-four patients (36 hips) admitted for cementless total hip replacement (THR) because of AS were enrolled in this study along with the control group of(More)
Segmental bone defects are a common obstacle in major orthopedic procedures, and the treatment of these defects remains a challenging clinical problem. Bone tissue engineering has been attracting much attention in recent years. We evaluated the ability of the specific combination of 3 microg rhVEGF(165) with a novel porous beta-tricalcium phosphate(More)
OBJECTIVE To study the effect of olfactory ensheathing cells (OECs) transplantation on protecting spinal cord and neurons after peripheral nerve injury. METHODS Fifty-five SD rats were randomly divided into blank group (n = 5), experimental group (n = 25) and control group (n = 25). The right sciatic nerves of all the rats were transected. The proximal(More)
OBJECTIVE To investigate the effects and possible mechanism of Panax Notoginseng saponins (PNS) on oxidative stress-induced damage and apoptosis in bone marrow stromal cells (BMSCs). METHODS BMSCs were isolated and cultured from 2-month-old New Zealand rabbits by the density gradient centrifugation combined with adherent method. The third passage cells(More)
OBJECTIVE To investigate the neuroprotective effects of recombinant adeno-associated virus (rAAV) expressing vascular endothelial growth factor (VEGF) on traumatic spinal cord injury (SCI) of rat and its mechanisms. METHODS The 144 male Sprague Dawley rats were randomly divided into 4 groups, and each group contained 36 rats. The rats in sham group (group(More)
BACKGROUND/AIMS Several shortcomings have limited the routine use of autogenous vascularized bone graft. The present study investigates the prefabrication of vascularized scaffold with the desired shape and microarchitecture combined with recombinant human vascular endothelial growth factor 165 (rhVEGF(165)) to mimic autogenous vascularized bone graft.
