And to further explore whether its therapeutic mechanism is related to the expression of HIF-1α and VEGF (angiogenic factors), BMP2 and Osterix (osteogenic factor), CD31 (type H vascular marker) and MMP13 (bone destruction-related factor). Methods: Twenty-seven healthy male New Zealand white rabbits were divided into a normal group, model group, traditional Chinese medcine (TCM) group (clinical equivalent dose group of YKP), miR-130a inhibitor group and TCM + inhibitor group. The SANFH model was established by combining horse serum with methylprednisolone. After the model is successfully established, TCM group was given 6.44 g/kg·d YKP by gavage, and the miR-130a gene inhibitor group was intraperitoneally injected with 25 mg/kg miR-130a inhibitor, locked nucleic acid (LNA)-anti-miR-130a. TCM + inhibitor group was treated with YKP intragastrically and miR-130a inhibitor intraperitoneally. The rabbits in the normal group and the model group were intragastrically administered with normal saline 10 ml/d. Once a day for 4 weeks. The avascular necrosis was detected by HE staining. The contents of HIF-1α, VEGF, BMP2 and Osterix in rabbit tissues were detected by qRT-PCR kit, and the expression of CD31 and MMP13 was detected by immunofluorescence staining. Results: In the normal group, the surface of the cartilage layer of the femoral head was smooth, the bone trabeculae were intact and densely arranged, the cells of each layer were neatly arranged, the morphology of the bone cells, the chondrocytes and the adipocytes were normal. In the model group, cartilage surfaces of the femoral head showed exfoliative cracks. The bone trabecular structure was loose and incomplete, chondrocytes, osteoblasts and bone marrow cells were significantly reduced, and the number of empty bone traps was significantly increased. In the TCM-treated group, more chondrocytes, thicker cartilage layer, and more regular bone trabeculae were detected as compared to model rabbits. In contrast, the cartilage layer was thinner, the destruction and fracture of bone trabeculae was more serious, chondrocytes and osteocytes were decreased as compared to model group. The expression of HIF-1α, VEGF, BMP2, and Osterix in the model group decreased significantly as compared to the normal group (P Conclusion: YKP can regulate the expression of angiogenic-related factors (VEGF and HIF-α), osteogenic-related factors (BMP2 and Osterix), and H-type vascular marker CD31, resulting in increased expressions of VEGF, HIF-α, BMP2, and Osterix, which promote intra-femoral head revascularization. Meanwhile, YKP decreased the expression of bone-destruction-related factor MMP13, thus enhancing the ability of bone tissue to repair itself. Regulation of these molecules’ expression may be one of the mechanisms of YKP in the treatment of hormonal femoral head necrosis.展开更多

Japanese white rabbits were randomly divided into three groups (control group, treatment group, and model group), each with 24 rabbits. The model and treatment groups were first injected with an intravenous dose of horse serum, 10 ml/kg, three weeks later with an intravenous dose of 7.5 ml/kg, and two weeks later with an intramuscular dose of methylprednisolone, 45 mg/kg, three times in order to establish rabbit models of osteonecrosis. Concurrently, the treatment group was injected with intravenous doses of SF 20 mg/kg for two weeks, once per day. Three time points, Weeks 2, 4, and 8, were selected after modeling was completed. Osteonecrosis was verified by histopathology with haematoxylin-eosin (HE) staining. The apoptosis rate of osteonecrosis was observed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The apoptosis expressions of caspase-3 and Bcl-2 were analyzed by immunohistochemistry and Western blot. The rabbit models of osteonecrosis were successfully established and observed by HE staining. SF was effective in intervening in apoptosis and decreasing the apoptosis rate in femoral head necrosis by the immunohistochemistry and TUNEL assay (P<0.01). Western blot analysis indicated that there were statistical significances in the protein levels of caspase-3 and Bcl-2 (P<0.01). SF has a protective effect by reducing the incidence of early steroid-induced femoral head necrosis in rabbits, effectively intervening in apoptosis through decreasing caspase-3 expression and up-regulating Bcl-2 expression.展开更多

In Group A, deproteinized bone (DPB) that absorbed with recombinant plasmid pcDNA3.1-hVEGF165 was implanted into the drilled tunnel of necrotic femoral head. In Group B, only DPB was implanted. In Group C, only tunnel was drilled without DPB or plasmid implanted. Femoral head specimens were obtained at postoperative 1, 2, 4, 8, 16 weeks. The expression of VEGF165 and collagen I was detected by immunohistochemistry. Bone formation was detected generally by X-ray. Angiogenesis and the repair of the femoral head were observed histologically.Results: The expression of VEGF 165 could be detected 2 weeks after implantation in Group A, but it was not observed in other groups. The result of collagen I expression had a significantly difference 2, 4 and 8 weeks after operation in Group A from those in other groups (P＜0.01).X-ray results indicated that there was more bone formation in Group A than in other groups. The regenerated capillary vessels staining result of necrotic femoral head in Group A was significantly different from those in other groups at postoperative 2 and 4 weeks (P＜0.01).Conclusions: Transfection ofhVEGF165 gene enhances local angiogenesis and DPB-VEGF compound improves the repair of necrotic femoral head. Deproteinized bone grafting with VEGF gene transfer provides a potential method for the treatment of osteonecrosis.展开更多

文摘In this article,the biodegradation process and bone formation of a mineralized collagen reconstruction rod embedding in necrosis of human femoral head were investigated by imageological and histological methods.Computed radiography(CR)computerized tomography(CT),common pathological section and hard tissue section analysis were used to evaluated the dynamics of imageological and histopathological changes of femoral head,interface between the host bone and implant and the bone reconstruction process.The results showed that the density of rods increased closed to that of host bones after 1 year implanting,and the interface between them turns to blurring.Hard tissue grinding sections analysis showed osteocytes appearing in sparse bone trabecular and bone pit region,as well as a few vessels in the degraded dye powder matrix were noticed,indicating the new bone forming between the implants and host bones.Regular decalcified sections analysis showed scattered osteoclasts,multinucleated giant cells and fibrosis components existing in the degraded rod and the host bone trabecular.Degraded debris was endocytosed by giant cells,and vascular network formed around the boundaries of the implanted rod.The good osteointegration has been expressed by the interface between the implanted rod and the host bone becoming blurred.Histological results indicated that the implanted rod degradation process and new bones regeneration simultaneously occurred around the boundaries of embedding rod.New bone and host bone were hinged and co-existed.

文摘To explore the relationship between preoperative traction and osteonecrosis of femoral head(ONFH)in patients with stable femoral neck fractures.Data from medical charts for 115 patients admitted to our institution with Garden II femoral neck fracture operated from January 2012 to December 2013 were extracted.Seven-year retrospective comparative study in the first affiliated hospital of Soochow University.Patients were divided into two groups by preoperative treatment:a preoperative traction group(group I)and a T-shaped shoe fixation group(group II).There were 14 patients lost to follow-up.101 patients with Garden II femoral neck fracture followed until July 2016 were available for complete analysis.Intervention:patients received skeletal traction or T-shaped shoe fixation preoperatively.All patients accepted internal fixation with multiple annulated screws.Main outcome measurements:the incidence of osteonecrosis of femoral head was analyzed based on preoperative traction,gender and implant removal.The average follow-up of these patients was 35 months(range,24-48 months).There was no implant failure or nonunion in our study.Nine patients(8.91%)had avascular necrosis.8(15.38%)patients in group I had osteonecrosis of femoral head,whereas only onepatient(2.04%)in group II had osteonecrosis of femoral head.Patients with preoperative traction had significantly higher incidence of osteonecrosis of femoral head compared with T shaped shoe fixation(P=0.032).No significant difference was found between the incidence of osteonecrosis of femoral head based on gender,age,injury-to-surgery interval time,implant removal or weight-bearing time.In patients with femoral neck fracture,preoperative traction may increase the incidence of osteonecrosis.Preoperative traction may not benefit patients with Garden II femoral neck fracture.The weight of traction may be a risk factor to osteonecrosis of femoral head.

文摘The aim of this study is to investigate the effects and possible mechanisms of sodium ferulate (SF) on anti-apoptosis in steroid-induced femoral head osteonecrosis in rabbits. Japanese white rabbits were randomly divided into three groups (control group, treatment group, and model group), each with 24 rabbits. The model and treatment groups were first injected with an intravenous dose of horse serum, 10 ml/kg, three weeks later with an intravenous dose of 7.5 ml/kg, and two weeks later with an intramuscular dose of methylprednisolone, 45 mg/kg, three times in order to establish rabbit models of osteonecrosis. Concurrently, the treatment group was injected with intravenous doses of SF 20 mg/kg for two weeks, once per day. Three time points, Weeks 2, 4, and 8, were selected after modeling was completed. Osteonecrosis was verified by histopathology with haematoxylin-eosin (HE) staining. The apoptosis rate of osteonecrosis was observed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The apoptosis expressions of caspase-3 and Bcl-2 were analyzed by immunohistochemistry and Western blot. The rabbit models of osteonecrosis were successfully established and observed by HE staining. SF was effective in intervening in apoptosis and decreasing the apoptosis rate in femoral head necrosis by the immunohistochemistry and TUNEL assay (P<0.01). Western blot analysis indicated that there were statistical significances in the protein levels of caspase-3 and Bcl-2 (P<0.01). SF has a protective effect by reducing the incidence of early steroid-induced femoral head necrosis in rabbits, effectively intervening in apoptosis through decreasing caspase-3 expression and up-regulating Bcl-2 expression.
文摘Objective: To explore a new method for early avascular necrosis of femoral head (AVNFH) therapy.Methods: Sixty-nine AVNFH New Zealand adult rabbits were randomly divided into three groups with equal number. In Group A, deproteinized bone (DPB) that absorbed with recombinant plasmid pcDNA3.1-hVEGF165 was implanted into the drilled tunnel of necrotic femoral head. In Group B, only DPB was implanted. In Group C, only tunnel was drilled without DPB or plasmid implanted. Femoral head specimens were obtained at postoperative 1, 2, 4, 8, 16 weeks. The expression of VEGF165 and collagen I was detected by immunohistochemistry. Bone formation was detected generally by X-ray. Angiogenesis and the repair of the femoral head were observed histologically.Results: The expression of VEGF 165 could be detected 2 weeks after implantation in Group A, but it was not observed in other groups. The result of collagen I expression had a significantly difference 2, 4 and 8 weeks after operation in Group A from those in other groups (P＜0.01).X-ray results indicated that there was more bone formation in Group A than in other groups. The regenerated capillary vessels staining result of necrotic femoral head in Group A was significantly different from those in other groups at postoperative 2 and 4 weeks (P＜0.01).Conclusions: Transfection ofhVEGF165 gene enhances local angiogenesis and DPB-VEGF compound improves the repair of necrotic femoral head. Deproteinized bone grafting with VEGF gene transfer provides a potential method for the treatment of osteonecrosis.
文摘A variety of techniques have been used for treating avascular necrosis of the femoral head(ANFH),but have frequently failed.In this study,we proposed aβ-TCP system for the treatment of ANFH by boosting revascularization and bone regeneration.The angio-conductive properties and concurrent osteogenesis of the highly interconnected porousβ-TCP scaffold were revealed and quantified through an in vivo model that simulated the ischemic environment of ANFH.Mechanical test and finite element analysis showed that the mechanical loss caused by tissue necrosis and surgery was immediately partially compensated after implantation,and the strength of the operated femoral head was adaptively increased and eventually returned to normal bone,along with continuous material degradation and bone regeneration.For translational application,we further conducted a multi-center open-label clinical trial to assess the efficacy of theβ-TCP system in treating ANFH.Two hundred fourteen patients with 246 hips were enrolled for evaluation,and 82.1%of the operated hips survived at a 42.79-month median follow-up.The imaging results,hip function,and pain scores were dramatically improved compared to preoperative levels.ARCO stage II disease outperformed stage III in terms of clinical effectiveness.Thus,bio-adaptive reconstruction using theβ-TCP system is a promising hip-preserving strategy for the treatment of ANFH.
文摘BACKGROUND The treatment of late stages of Legg-Calvé-Perthes disease(LCPD)is controversial.Although the concept of femoral head containment is a well-established technique of treatment,its use remains debatable in the late stages of the disease,as it does not improve symptoms in terms of limb length discrepancy and gait.AIM To assess the results of subtrochanteric valgus osteotomy in symptomatic patients with late-stage Perthes disease.METHODS From 2000 to 2007,36 symptomatic patients with late stage of Perthes disease were surgically treated with subtrochanteric valgus osteotomy and followed-up for 8 to 11 years using the IOWA score and range of motion(ROM)variables.The Mose classification was also assessed at the last follow-up to reflect possible remodeling.The patients were 8 years old or older at the time of surgery,in the post-fragmentation stage,and complaining of pain,limited ROM,Trendelenburg gait,and/or abductor weakness.RESULTS The preoperative IOWA score(average:53.3)markedly improved at the 1-year post follow-up period(average:85.41)and then slightly improved at the last follow-up(average:89.4)(P value<0.05).ROM improved,with internal rotation increased on average by 22°(from 10°preoperatively to 32°postoperatively)and abduction increased on average by 15.9°(from 25°preoperatively to 41°postoperatively).The mean Mose deviation of femoral heads was 4.1 mm at the end of the follow-up period.The tests used were the paired t-test and Pearson correlation test,where the level of significance was a P value less than 0.05.CONCLUSION Subtrochanteric valgus osteotomy can be a good option for symptomatic relief in patients with late-stage of LCPD.
