Biomechanical Characteristics of Osteoporotic Fracture Healing in Ovariectomized Rats: A Systematic Review

Biomechanical tests are widely used in animal studies on osteoporotic fracture healing. However, the biomechanical recovery process is still unknown, leading to difficulty in choosing time points for biomechanical tests and in correctly assessing osteoporotic fracture healing. To determine the biomechanical recovery process during osteoporotic fracture healing, studies on osteoporotic femur fracture healing with biomechanical tests in ovariectomized rat (OVX) models were collected from PUBMED, EMBASE, and Chinese databases. Quadratic curves of fracture healing time and maximum load were fitted with data from the analyzed studies. In the fitted curve for normal fractures, the predicted maximum load was 145.56 N, and the fracture healing time was 88.0 d. In the fitted curve for osteoporotic fractures, the predicted maximum load was 122.30 N, and the fracture healing time was 95.2 d. The maximum load of fractured femurs in OVX rats was also lower than that in sham rats at day 84 post-fracture (D84 PF). The fracture healing time was prolonged and maximum load at D84 PF decreased in OVX rats with closed fractures. The maximum load of Wister rats was higher than that of Sprague-Dawley (SD) rats, but the fracture healing time of SD and Wister rats was similar. Osteoporotic fracture healing was delayed in rats that were < = 12 weeks old when ovariectomized, and at D84 PF, the maximum load of rats < = 12 weeks old at ovariectomy was lower than that of rats >12 weeks old at ovariectomy. There was no significant difference in maximum load at D84 PF between rats with an osteoporosis modeling time <12 weeks and > = 12 weeks. In conclusion, fracture healing was delayed and biomechanical property decreased by osteoporosis. Time points around D95.2 PF should be considered for biomechanical tests of osteoporotic femur fracture healing in OVX rat models. Osteoporotic fracture healing in OVX rats was affected by the fracture type but not by the strain of the rat.     

Yeast-Incorporated Gallium Promotes Fracture Healing by Increasing Callus Bony Area and Improving Trabecular Microstructure on Ovariectomized Osteopenic Rats

The purpose of this study was to analyze the impact of yeast-incorporated gallium on fracture healing in ovariectomized osteopenic rats. Forty Wistar female rats used were divided into three groups: sham-operated rats (SHAM), ovariectomized (OVX) rats, and ovx rats treated with yeast-bound gallium (YG). A standardized fracture-healing model with stable plate fixation was established for rat femoral. After 4-week stable fixation, animals were killed to prepare bones for Micro-CT, biomechanical testing, and histomorphometry. In addition, bone samples were obtained to evaluate the content of mineral substances in bones. Quantitative analysis of the bones from animals in the organic gallium group revealed significantly increased mineral contents compared to bones from OVX and SHAM groups. Micro-CT showed that treatment with yeast-incorporated gallium increased BV/TV and trabecular thickness and decreased trabecular separation in ovx animals. Histomorphometric evaluation demonstrated that YG increased callus area and callus bone formation. Yeast-bound gallium also improved the biomechanical properties of bone healing. In conclusion, this study suggests that yeast-incorporated gallium could promote fracture healing in ovariectomized rats.

Expression of Sclerostin scFv and the Effect of Sclerostin scFv on Healing of Osteoporotic Femur Fracture in Rats

Osteoporosis is a systemic metabolic disease characterized by low bone mass with deterioration of the bony microstructure which leads to both bone brittleness and increased risk of fracture. Sclerostin is a protein encoded by the SOST gene which is specifically expressed in osteocyte. Monoclonal antibodies of sclerostin can promote bone formation by antagonizing its inhibitory action. However, the effectiveness of monoclonal antibodies to exert such effects are limited by the large molecular mass and high immunogenicity. Here, we report that we purified a high immune affinity, single-chain antibody of SOST: SOST–single-chain Fv (scFv). Real-time polymerase chain reaction amplification of the variable regions of the heavy- and light-chain gene from a secretory anti-SOST antibody was performed. Animal experiments showed that SOST–scFv promoted bone healing in a rat model of osteoporosis.     

Expression of RANKL/OPG during bone remodeling in vivo

The interaction between receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) plays a dominant role in osteoclastogenesis. As both proteins are produced by osteoblast lineage cells, they are considered to represent a key link between bone formation and resorption. In this study, we investigated the expression of RANKL and OPG during bone remodeling in vivo to determine the relationship between osteoclastogenic stimulation and osteoblastic differentiation.Total RNA was prepared from rat femurs after marrow ablation on days 0, 3, 6, and 9. The temporal activation patterns of osteoblast-related genes (procollagen α1 (I), alkaline phosphatase, osteopontin, and osteocalcin) were examined by Northern blot analysis. An appreciable increase in the expression of these osteoblast markers was observed on day 3. The peak increase in gene expression was observed on day 6 followed by a slight reduction by day 9. Real-time PCR analysis showed that the OPG mRNA expression was markedly upregulated on day 6 and slightly decreased on day 9. In contrast, RANKL mRNA expression was increased by more than 20-fold on day 9. The RANKL/OPG ratio, an index of osteoclastogenic stimulation, peaked on day 9. Histological analysis showed that RANKL and OPG immunoreactivity were predominantly associated with bone marrow cells. The expression of bone formation markers was activated in the bone formation phase, followed by the stimulation of RANKL/OPG expression in the bone resorption phase, which confirmed that these molecules are key factors linking bone formation to resorption during bone remodeling.

粪便微生物系移植通过影响炎症因子和肠道菌群结构缓解大鼠实验性结肠炎

炎症性肠病（inflammatory bowel disease,IBD）病因虽未明确,但目前认为,肠道细菌和肠黏膜免疫功能紊乱与IBD的发病密切相关。将40只SD大鼠分为健康对照组、模型组、粪便微生物系移植组（fecal microbiota transplantation,FMT）和柳氮磺胺吡啶组,后3组用2,4,6-三硝基苯磺酸（2,4,6-trinitrobenzene sulfonic acid, TNBS）灌肠造模,造模2 d后分别用粪便悬液和柳氮磺胺吡啶治疗1 w。末次给药后禁食1 d,对大鼠粪便进行菌群成分分析,股动脉取血,对K⁺ 、Na⁺ 、血清白蛋白（ALB）、白细胞计数（WBC）、中性粒细胞百分率（N%）、C-反应蛋白（CRP）、IL-1β、IL-10、IL-12和IL-17 水平进行检测,取结肠行病理学检查。结果发现,通过TNBS灌肠成功建立大鼠实验性结肠炎模型。与模型组比较,FMT组的K⁺和ALB明显升高(P<0.05),WBC、N%和CRP明显降低(P<0.05),IL-1β和IL-17明显降低(P<0.05),IL-10和IL-10/IL-12含量升高(P<0.05)。FMT能显著改善TNBS引起的肠道菌群变化,促进双歧杆菌的增殖而抑制脆弱拟杆菌和大肠杆菌的生长。上述结果证明,FMT可有效治疗炎症性肠病,其机制与其影响血清炎症因子水平和改善肠道菌群有关。

Bone cancer pain and the role of RANKL/OPG

Cancer-induced bone diseases are common and can have a devastating impact at the end of life. One of the most difficult sequelae of cancer is metastases to the skeleton, an event that results in bone destruction and bone cancer pain. Bone cancer pain is usually progressive as the disease advances, and is particularly difficult to treat. Recently, experimental models of bone cancer pain have been developed and have provided seminal insight in understanding the pathophysiology of bone cancer pain. Animal models of bone cancer provided the finding that bone destruction (osteolysis) is associated with pain, and it has been determined that cancer-induced osteolysis is mediated by osteoclasts. Having established that RANK ligand contributed to cancer-induced osteoclastogenesis, it was determined that disruption of the RANKL-RANK axis with OPG inhibited tumor-induced osteoclastogenesis and decreased bone cancer pain.     

Variation in Gene Expression of Inflammatory Cytokines in Leukocyte-Derived Cells of High-Fat-Diet-Induced Insulin-Resistant Rats

A high-fat diet is thought to enhance inflammation in various tissues by increasing insulin resistance. In this study, we determined the mRNA levels of inflammatory cytokines in leukocyte-derived cells in the blood of rats with high-fat-diet-induced insulin resistance. Feeding rats a high-fat diet for 77 d induced moderate insulin resistance, which was determined by increased plasma glucose and insulin concentrations, following an oral glucose tolerance test. The interleukin (IL)-1β mRNA level was higher in the insulin-resistant rats than in control rats at the fasting stage, whereas the tumor necrosis factor (TNF)-α mRNA level was greatly elevated at 180 min after glucose administration in the insulin-resistant rats. The results suggest that feeding rats a high-fat diet enhances the expression of fasting IL-1β and postprandial TNF-α genes in leukocyte-derived cells.     

Functions of RANKL/RANK/OPG in bone modeling and remodeling

The discovery of the RANKL/RANK/OPG system in the mid 1990s for the regulation of bone resorption has led to major advances in our understanding of how bone modeling and remodeling are regulated. It had been known for many years before this discovery that osteoblastic stromal cells regulated osteoclast formation, but it had not been anticipated that they would do this through expression of members of the TNF superfamily: receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG), or that these cytokines and signaling through receptor activator of NF-κB (RANK) would have extensive functions beyond regulation of bone remodeling. RANKL/RANK signaling regulates osteoclast formation, activation and survival in normal bone modeling and remodeling and in a variety of pathologic conditions characterized by increased bone turnover. OPG protects bone from excessive resorption by binding to RANKL and preventing it from binding to RANK. Thus, the relative concentration of RANKL and OPG in bone is a major determinant of bone mass and strength. Here, we review our current understanding of the role of the RANKL/RANK/OPG system in bone modeling and remodeling.     

Protective Effects of Gallium, Germanium, and Strontium Against Ovariectomized Osteoporosis in Rats

The effects of trace elements of gallium (Ga), germanium (Ge), and strontium (Sr) on ovariectomized (OVX) osteopenic rats were studied in this paper. The urine calcium content, serum calcium, and phosphorus contents, bone mineral content, mineral dissolution, and mechanical strength of the osteopenic rats were analyzed respectively. After the rats were fed with Ga, Ge, and Sr diet for 8 weeks, respectively, the urine calcium content decreased (P?<?0.01). Plasma calcium and phosphate concentrations decreased in the order of OVX group?>?Ge group?>?Sr group?>?Ga group?>?Sham group. Mineral content increased in the order of OVX group?<?Ge group?<?Sr group?<?Ga group?<?Sham group. A dramatic decrease in calcium solubility was found both in the gallium and strontium treated animals (P?<?0.05). However, the same result did not occur in germanium treated groups. The data provide an important proof of concept that gallium and strontium might be a new potential therapy for the management of postmenopausal osteoporosis in humans.

Short-term Administration of Water-soluble Silicon Improves Mineral Density of the Femur and Tibia in Ovariectomized Rats

Silicon is important for the proper growth and development of bone and connective tissues. This study was designed to investigate if water-soluble silicon could be used for the treatment of postmenopausal osteoporosis. Silicon (Si 20 mg/kg body weight/day) was administrated orally to 17-week-old ovariectomized (OVX) rats for 4 weeks. Silicon did not alter weight gain in OVX rats. Silicon supplementation significantly increased the bone mineral density of the femur (p < 0.05, vs. OVX control group) and tibia in OVX rats (p < 0.05, vs. OVX control group). Serum alkaline phosphatase and osteocalcin, two bone formation biomarkers tested, were not significantly altered, but urinary calcium and phosphorous excretion tended to decrease with silicon supplementation. OVX rats with silicon supplementation showed a relatively higher serum CTx compared to the nonsupplemented OVX group (p < 0.01, vs. OVX control group). According to these results, short-term soluble silicon supplementation improved bone mineral density in OVX-induced osteoporosis.
