Effects of Yougui recipe on the behavioral changes in rat of steroid-induced avascular necrosis of the femoral head / 中国骨伤

<p><b>OBJECTIVE</b>To explore the effect of Yougui Recipe, a kidney-supplementing and yang-activating formula which on the behavioral changes of rat of steroid-induced avascular necrosis of the femoral head (SANFH).</p><p><b>METHODS</b>Thirty Wistar rats were involved and were randomly divided into the blank control group (group A), the model group (group B) and the Yougui Recipe group (group C). SANFH models were established by injection of colibacillus endotoxin and prednisolone intramuscularly. Group C was lavaged with Yougui Recipe (10 ml/kg), while group A and group B were lavaged with the same amount of saline. The behavior of catch force, independent activities, the tail suspension, field experiment and water cleans maze experiment were observed after 6 weeks.</p><p><b>RESULTS</b>Compared with Yougui Recipe, rats in model group: catch force and independent activity decreases; the tail suspension activities was less time. In the desert field experiments, the total distance in 10 min movement reduced significantly. In the water maze experiment, incubation period of escape had a long time obviously, total distance of activities reduced.</p><p><b>CONCLUSION</b>Yougui Recipe can relieve the ethologic change of rat model of steroid-induced avascular necrosis of the femoral head.</p>

Research progress on proteomics in femur head necrosis / 中国骨伤

Appearance of proteomics technology can fleetly filt and reveal specificity biomarkers of disease, this will help to reveal the pathogenesis of femur head necrosis and help early diagnosis, find more effective methods and therapeutic targets. At present, they are hot spots that find out the occurred mechanism,related proteins of early diagnosis and early treatment and its functional identification; set up the early related database; optimize the protein extraction methods for research of femur head necrosis. This article reviews the application of study technology of related proteins of femur head necrosis on bone tissue, serum,related animal model,and in order to provide further research ideas.

Experimental study on Yougui recipe in preventing osteolysis surrounding artificial prosthesis / 中国骨伤

<p><b>OBJECTIVE</b>To explore effects of Yougui recipe (see text) and salmon calcitonin acetate in preventing osteolysis surrounding artificial prosthesis.</p><p><b>METHODS</b>Thirty-two SD male rats with weighted (250 +/- 20) g, aged 8 weeks, were randomly divided into four groups: blank group, model group, salmon calcitonin acetate group and Yougui recipe (see text) group, and 8 rats in each group. Blank group did not undergo any process, other 24 rats underwent anesthesia by chloral hydrate, their knee joints were exposed through medial patellar side,drilling from fermoral condyle nest to marrow cavity,high density of polythlene particles were injected into hole, titanium nail were put into, bone wax closed the window, then suturing step by step. After the molding, saline were used to gavaged in blank group and model group, Yougui recipe (see text) for Yougui recipe (see text) group, salmon calcitonin maximus injection for calcitonin group. After 10 weeks' mediation, rats were executed, and arterial blood and bilateral femoral organization were collected to biochemical, imaging morphology, tissue pathology and molecular biology detection.</p><p><b>RESULTS</b>The key gene expression of activiting osteoclast were inhibited in Yougui recipe (see text) group and calcitonin group. The level of OPG, Ca, ALP in Yougui recipe group were higher than calcitonin group (P<0.01); the content of RANKL were lower (P<0.01). There were no significance meaning in RANK, Trap5b, P between two groups.</p><p><b>CONCLUSION</b>Both of Yougui recipe (see text) and calcitonin can slow and treat surrounding osteolysis of artificial joint prosthesis, and Yougui recipe (see text) has better effect in promoting bone formation. The effect of Yougui recipe (see text) in promoting bone formation, inhibiting osteoclasts to provide a new method to treating surrounding osteolysis of artificial joint prosthesis.</p>
