BACKGROUND Hip fractures are always associated with a high postoperative mortality, the preoperative predictors for mortality have neither been well identified or summarised. This systematic review and meta-analysis was performed to identify the preoperative non-interventional predictors for mortality in hip fracture patients, especially focused on 1 year(More)
Autophagy is an intracellular catabolic mechanism that maintains the balance of proteins, lipids and aging organelles. 3-Methyladenine (3-MA) is a selective inhibitor of autophagy, whereas rapamycin, an antifungal agent, is a specific inducer of autophagy, inhibiting the protein mammalian target of rapamycin. In the present study, we examined the role of(More)
It has been argued that gamma-secretase should be considered as a pharmacological target, as there are few mechanism-based experimental and clinical studies on gamma-secretase treatment. In this study, we found that N2a cells bearing APP695 or its Swedish mutant exhibited increased basal levels of ROS, nitric oxide (NO), protein carbonyls, MDA and(More)
BACKGROUND Long-bone fractures are very common in trauma centers. The conventional Arbeitsgemeindschaft fur Osteosynthesefragen (AO) technique contributes to most fracture healing problems, and external fixation technology also has several disadvantages, so new techniques are being explored. METHOD A novel hexapod computer-assisted fracture reduction(More)
Intertrochanteric fractures in elderly patients are always associated with poor prognosis in the functional outcome as a result of the complications and mortality. A retrospective study was performed in our institution, 303 consecutive patients were followed up with mean age of 81.7 years. 147 were treated with PFNA, and 156 were underwent hemiarthroplasty.(More)
OBJECTIVE The objective of this study was to compare treatment results and complication rates between lateral and posterior approaches in surgical treatment of extra-articular distal humeral shaft fractures. MATERIAL AND METHODS Between June 2008 and May 2012, a total of 68 patients with extra-articular distal humeral shaft fractures were treated by(More)
Bone remodeling involves bone resorption by osteoclasts and synthesis by osteoblasts and is tightly regulated by the receptor activator of the NF-kappaB ligand (RANKL)/receptor activator of the NF-kappaB (RANK)/osteoprotegerin molecular triad. RANKL, a member of the TNF superfamily, induces osteoclast differentiation, activation and survival upon(More)
Murine C3H10T1/2 cells have many features of mesenchymal stem cells (MSCs). Whether or not the multipotent differentiation capability of C3H10T1/2 cells is comparable to that of primary bone marrow–derived MSCs (BM-MSCs) was investigated in this study. For in vitro osteogenic differentiation, both BM-MSCs and C3H10T1/2 cells differentiated to osteoblastic(More)
OBJECTIVE The objective of this study was to evaluate the effectiveness of the treatment of infected nonunion of tibia and femur by bone transport. MATERIAL AND METHODS We retrospectively reviewed 110 patients with infected nonunion of tibia and femur treated by bone transport. Our study included 92 males and 18 females with a mean age of 38.90 years. The(More)
Osteoclasts are the exclusive cells of bone resorption. Abnormally activating osteoclasts can lead to low bone mineral density, which will cause osteopenia, osteoporosis, and other bone disorders. To date, the mechanism of how osteoclast precursors differentiate into mature osteoclasts remains elusive. MicroRNAs (miRNAs) are novel regulatory factors that(More)
