目的:探讨药物“99 Tc-MDP”治疗股骨头无菌性坏死( ANFH)的价值。方法动物实验分为2个阶段:制作模型阶段和治疗观察阶段。第1阶段:设A组(正常组)、B组(股骨头无菌性坏死模型组),采用肌肉注射地塞米松磷酸钠注射液制作ANFH动物模型,时间为8周。检测骨病理学、骨形态计量检测、骨密度、四环素双标记试验、核素骨骼显像感兴趣区( ROI )比值、X线摄片、CT摄片等指标,在证实ANFH动物模型成立后再进行第2阶段实验。第2阶段,在ANFH模型的基础上,设C组(正常对照组)、D组(股骨头无菌性坏死模型对照组)、E组(“99 Tc-MDP”治疗组)、F组(阿伦膦酸钠治疗组),治疗组的疗程为16周,治疗结束,对E组、F组的疗效进行评判。统计学采用SPSS13.0软件分析数据。结果经过第1、2阶段的ANFH模型制作和治疗后,在骨病理学、骨形态计量、骨密度、四环素双标记试验骨转换值、核素骨骼显像( ROI)等检测结果显示,A组与B组各指标差异明显(P<0.01),ANFH模型成立。经治疗后的E组在骨病理学显示,股骨头骨小梁排列较规则,呈略有稀疏现象,在D组的基础上修复明显;F组则表现为股骨头骨小梁稀疏、排列不规则,偶有断裂现象,但较D组有所改善,也得到骨密度、四环素双标记试验骨转换值、“99mTc-MDP”骨骼显像ROI比值等检测结果的支持(P<0.05)。结论在ANFH动物模型的基础上经“99 Tc-MDP”、“阿仑膦酸钠”治疗后,得到不同的疗效,以“99 Tc-MDP”治疗后修复明显。“99 Tc-MDP”能靶向性地到达ANFH部位,除了具有抑制骨吸收,而且还存在保护超氧化物歧化酶( SOD)的活力,防止自由基对骨组织的破坏,对损伤骨组织的作用有抑制价值。从四环素双标记试验中所示的骨矿化沉积率增高可能与促进骨细胞的增殖有关。
目的:探討藥物“99 Tc-MDP”治療股骨頭無菌性壞死( ANFH)的價值。方法動物實驗分為2箇階段:製作模型階段和治療觀察階段。第1階段:設A組(正常組)、B組(股骨頭無菌性壞死模型組),採用肌肉註射地塞米鬆燐痠鈉註射液製作ANFH動物模型,時間為8週。檢測骨病理學、骨形態計量檢測、骨密度、四環素雙標記試驗、覈素骨骼顯像感興趣區( ROI )比值、X線攝片、CT攝片等指標,在證實ANFH動物模型成立後再進行第2階段實驗。第2階段,在ANFH模型的基礎上,設C組(正常對照組)、D組(股骨頭無菌性壞死模型對照組)、E組(“99 Tc-MDP”治療組)、F組(阿倫膦痠鈉治療組),治療組的療程為16週,治療結束,對E組、F組的療效進行評判。統計學採用SPSS13.0軟件分析數據。結果經過第1、2階段的ANFH模型製作和治療後,在骨病理學、骨形態計量、骨密度、四環素雙標記試驗骨轉換值、覈素骨骼顯像( ROI)等檢測結果顯示,A組與B組各指標差異明顯(P<0.01),ANFH模型成立。經治療後的E組在骨病理學顯示,股骨頭骨小樑排列較規則,呈略有稀疏現象,在D組的基礎上脩複明顯;F組則錶現為股骨頭骨小樑稀疏、排列不規則,偶有斷裂現象,但較D組有所改善,也得到骨密度、四環素雙標記試驗骨轉換值、“99mTc-MDP”骨骼顯像ROI比值等檢測結果的支持(P<0.05)。結論在ANFH動物模型的基礎上經“99 Tc-MDP”、“阿崙膦痠鈉”治療後,得到不同的療效,以“99 Tc-MDP”治療後脩複明顯。“99 Tc-MDP”能靶嚮性地到達ANFH部位,除瞭具有抑製骨吸收,而且還存在保護超氧化物歧化酶( SOD)的活力,防止自由基對骨組織的破壞,對損傷骨組織的作用有抑製價值。從四環素雙標記試驗中所示的骨礦化沉積率增高可能與促進骨細胞的增殖有關。

Objective To investigate the value of 99 Tc-MDP therapy in aseptic necrosis femur head ( ANFH) .Methods The animal experiment was divided into 2 stages: animal model establishment and clinical observation.In the first stage, Group A ( normal group) and Group B ( ANFH group) were set up.The animal ANFH model was established by intravenous injection of dexamethasone sodium phosphate for 8 weeks.Bone pathology, histomorphology, bone mineral density, tetracycline double labeling experiment, radionuclide bone scintigraphy ROI ratio value, X-ray, and CT were examined.The second stage of the experiment started until the ANFH model had been proved.During the second stage, these groups were set up for the further 16 week-therapy based on the ANFH animal model: Group C (normal control), Group D (ANFH control), Group E (99Tc-MDP therapy) , and Group F ( alendronate therapy) .After the treatment, the efficacy in Group E and Group F was valued.A SPPSS 13.0 software was used for statistical analysis.Results After 2 stages of ANFH model establishment and clinical observation, the results, including bone pathology, histomorphology, bone mineral density, tetracycline double labeling experiment, and ROI ratio of radionuclide bone scintigraphy, showed apparent difference between Group A and B (p<0.01), indicating the success of animal modeling.After the treatment, the bone pathology in Group E showed that trabecular bone in the femoral head lined regularly with a little scatter.But the repair was apparent comparing with that in Group D.In Group F trabecular bone in the femoral head showed scattered and irregular lining and little broken.Comparing with that in Group D, the situation improved in Group F.The results of bone mineral density, tetracycline double labeling experiment, and ROI ratio of radionuclide bone scintigraphy also supported the improvement ( p<0.05 ) .Conclusion On the bases of ANFH animal model,99 Tc-MDP and Alendronate have got different therapy value and 99 Tc-MDP showed an apparent remoulding result.99 Tc-MDP can reach the ANFH target tissue.Besides controlling bone absorption, it also can maintain the activity of superoxide dismutase( SOD) , protect the bone tissue absorption from free radius and prevent from its further damaging.From the tetracycline double labeling experiment we can conclude that the increased deposition rate maybe relate to the bone cell proliferation.
