    Abstract Sixty-four New Zealand rabbits were used in this experiment. Four animals served as controls and the other 60 were plated on their left tibia with stainless steel plates. They were divided into 3 groups, from which the plates were removed 2, 3 and 4 months after implantation respectively. Four animals in each group were sacrificed immediately after plate removal and the others were killed 1, 2, 3 and 4 months later. Image analysis of microsection of the cortical bone underneath the plate was performed by an automatic image analysis instrument. Results showed that prolonged plate fixation would greatly retard the recovery rate of the local osteoporosis induced by plate fixation. To reduce the incidence of refracture of the plated bone, the rigid plate should be removed as soon as a fracture is closed.

    Abstract When performing total hip replacement (THR) in high dislocated hips, the presence of soft-tissue contractures means that most surgeons prefer to use a femoral shortening osteotomy in order to avoid the risk of neurovascular damage. However, this technique will sacrifice femoral length and reduce the extent of any leg-length equalisation. We report our experience of 74 THRs performed between 2000 and 2008 in 65 patients with a high dislocated hip without a femoral shortening osteotomy. The mean age of the patients was 55 years (46 to 72) and the mean follow-up was 42 months (12 to 78). All implants were cementless except for one resurfacing hip implant. We attempted to place the acetabular component in the anatomical position in each hip. The mean Harris hip score improved from 53 points (34 to 74) pre-operatively to 86 points (78 to 95) at final follow-up. The mean radiologically determined leg lengthening was 42 mm (30 to 66), and the mean leg-length discrepancy decreased from 36 mm (5 to 56) pre-operatively to 8.5 mm (0 to 18) postoperatively. Although there were four (5%) post-operative femoral nerve palsies, three had fully resolved by six months after the operation. No loosening of the implant was observed, and no dislocations or infections were encountered. Total hip replacement without a femoral shortening osteotomy proved to be a safe and effective surgical treatment for high dislocated hips.

    Abstract Turbid return water from converter is a kind of dust scrubbing wastewater with both high suspended solid concentration and high turbidity, which contains suspended particles such as iron oxide, calcium oxide, silicon oxide, and so on. Usually, it is treated with flocculating sedimentation method, but the addition of flocculant would result in the higher operating cost. In this study, the wastewater from converter was disposed by superconducting high gradient magnetic separation technology. The experimental results showed us that it very useful for both pollutants separation and reuse of wastewater from converter. With the X-ray diffraction analysis, scanning electron microscopy and particles size analysis, the results indicated that not only the ferromagnetic iron oxide, but also weak magnetic substance such as calcium oxide and silica, and nanometer particles could be magnetically coagulated and trapped. Therefore, the suspended solid concentration could be stably controlled as less than 10mg/L, and the wastewater could be recycled completely at the magnetic field gradient of 3T. The data reported in this study suggest that the superconducting high gradient magnetic separation technology has a great application prospect: it could be applied without changing the main conventional wastewater treatment process, and it has the advantages of low investment and operating cost, easy and simple handling, and saving water and energy as well.

    Abstract In search of anti-bone resorbing agents for the potential treatment of osteoporosis, we synthesized a novel compound Tert-butyl 4-(3-[1H-indole-2-carboxamido]benzoyl)piperazine-1-carboxylate (OA10) and found that OA10 is capable of inhibiting RANKL-mediated osteoclast formation and osteoclastic bone resorption in a dose-dependent manner. This biological effect is further supported by the fact that OA10 suppressed osteoclastic-specific gene expression, including tartrate-resistant acid phosphatase, cathepsin K receptor, and calcitonin receptor. Further molecular mechanism investigation revealed OA10 inhibited p38 phosphorylation, suppressed c-fos and NFATc1 expression without affecting NF-κB or JNK signaling pathways. Taken together, this study suggested that OA10 can inhibit osteoclastogenesis by suppressing p38-c-Fos-NFATc1 cascade. OA10 may be developed as a therapeutic drug for osteoclast-related osteolytic diseases.

    Abstract Osteoclasts are one of the key therapeutic targets for a variety of orthopedic diseases such as osteoporosis and osteoarthritis. In this study, we synthesized a novel compound N-(3-(cyclohexylcarbamoyl) phenyl)-1H-indole-2- carboxamide (termed as OA-4) and investigated the effects of OA-4 on the differentiation and function of osteoclasts. OA-4 markedly diminished osteoclast differentiation and osteoclast specific gene expression in a dose-dependent manner. In addition, OA-4 dose-dependently suppressed osteoclastic bone resorption. Furthermore, we found OA-4 attenuated RANKL-induced p38 phosphorylation without affecting JNK or NF-κB signaling pathways. Collectively, we synthesized a novel compound OA-4 which can inhibit osteoclast formation and functions via the suppression of p38 signaling pathway.

    Abstract Twenty-four New Zealand white rabbits were plated on their intact left tibiae with stainless steel plates and 4 animals served as controls. The plates were removed 2 months after implantation in 20 plated animals. Of them, 4 were sacrificed immediately after plate removal and the other 16 were killed in successive groups with 4 in each group 1,2,3 and 4 months after plate removal respectively. The remaining 4 plated animals were killed at 6 months after implantation. Bone samples under the plates were harvested and prepared for polarized light microscopy to investigate the repair of the regional osteoporosis induced by rigid implant. The results indicated that the regional osteoporosis could recover gradually after plate removal. The repair process manifested itself mainly as the repair of resorption cavities and the remodeling of collagen fibers. The orientation of the collagen fibers remained disorganized when the resorption cavities had been repaired. It is suggested that delayed restoration of bone structure might be one of the potential causes of refracture after removal of the rigid implant.

    Abstract Bone defects larger than a critical size are major challenges in orthopedic medicine. We combined tissue-engineered bone and gene therapy to provide osteoprogenitor cells, osteoinductive factors, and osteo-conductive carrier for ideal bone regeneration in critical-sized bone defects. Goat diaphyseal bone defects were repaired with tissue and genetically engineered bone implants, composed of biphasic calcined bone (BCB) and autologous bone marrow derived mesenchymal stem cells (BMSC) transduced with human bone morphogenetic protein-2 (hBMP-2). Twenty six goats with tibial bone defects were divided into groups receiving implants by using a combination of BCB and BMSCs with or without the hBMP-2 gene. In eight goats that were treated with BCB that contained hBMP-2 transduced BMSC, five had complete healing and three showed partial healing. Goats in other experimental groups had only slight or no healing. Furthermore, the area and biochemical strength of the callus in the bone defects were significantly better in animals treated with genetically engineered implants. We concluded that the combination of genetic and tissue engineering provides an innovative way for treating critical-sized bone defects.

    Abstract Forty adult New Zealand rabbits were used in this experiment. Four rabbits served as control and the rest 36 being divided into 3 groups, each of which was fixed respectively with methylmethacrylate, titanium alloy and stainless steel plate on the left intact tibiae. The cortical bone beneath the plate was harvested at 2, 4, 8 and 12 weeks after operation and observed by means of using transmission electron microscope. The major ultrastructural changes after internal fixation with different stiffness plates were alteration of osteocyte life cycle, perilacunar matrix and disorder of osteoblast and osteoblast coupling. The greater the stiffness of the plate, the greater the ultrastructural change.

    Abstract We report on the first search for Λ[over ¯]-Λ oscillations in the decay J/ψ→pK^{-}Λ[over ¯]+c.c. by analyzing 1.31×10^{9}  J/ψ events accumulated with the BESIII detector at the BEPCII collider. The J/ψ events are produced using e^{+}e^{-} collisions at a center of mass energy sqrt[s]=3.097  GeV. No evidence for hyperon oscillations is observed. The upper limit for the oscillation rate of Λ[over ¯] to Λ hyperons is determined to be P(Λ)=[B(J/ψ→pK^{-}Λ+c.c.)/B(J/ψ→pK^{-}Λ[over ¯]+c.c.)]<4.4×10^{-6} corresponding to an oscillation parameter δm_{ΛΛ[over ¯]} of less than 3.8×10^{-18}  GeV at the 90% confidence level.
