文题释义:
骨力学:研究骨和软骨的目的在于剖析骨和骨骼系统的力学性质,揭示骨骼生长、发育腑变、衰退和死亡同力学作用间相互关系,给出生命科学中这类力学问题的精确的定量分析。建立本构关系是对骨和软骨这类生物材料进行力学分析首先要解决的问题。目前,骨和软骨的本构关系和模型基本上还处在借用工程材料的本构关系的状态。尽管如此,据此做出的不少骨骼力学分析仍是很有意义的。对骨骼,如颅骨、股骨、脊椎骨、膝盖骨等作出的许多静力学和动力学的分析,与临床表现很接近。这些分析对于生物医学工程颇具指导意义。
弹性模量:一般地讲,对弹性体施加一个外界作用力,弹性体会发生形状的改变(称为“应变”),“弹性模量”的一般定义是:单向应力状态下应力除以该方向的应变。材料在弹性变形阶段,其应力和应变成正比例关系(即符合胡克定律),其比例系数称为弹性模量。弹性模量的单位是达因每平方厘米。“弹性模量”是描述物质弹性的一个物理量,是一个统称,表示方法可以是“杨氏模量”、“体积模量”等。
摘要
背景:
以压缩、弯曲力学性能指标评估仙灵骨葆胶囊等多种药物治疗老龄雌性骨质疏松模型动物的效果目前鲜有报道。
目的:对以仙灵骨葆胶囊、阿仑膦酸钠、钙尔奇、甲状旁腺激素(3-34).牛干预治疗的骨质疏松模型大鼠股骨、胫骨进行压缩、弯曲实验,确定各种药物对骨质疏松的治疗效果。
方法:以去双侧卵巢的方法建立雌性大鼠骨质疏松模型,分别以仙灵骨葆胶囊、阿仑膦酸钠、钙尔奇、甲状旁腺激素(3-34).牛进行干预治疗,给药20周。给药20周后,以腹主动脉放血法处死各组大鼠,解剖取各组大鼠左、右侧股骨进行压缩实验,取大鼠左、右侧胫骨进行弯曲实验。
结果与结论:①股骨压缩实验:模型组大鼠股骨压缩弹性应力、弹性载荷、弹性应变、弹性位移、最大载荷、最大应变、最大应力、最大位移、弹性模量均显著低于正常对照组、阿仑膦酸钠组、仙灵骨葆胶囊组、甲状旁腺激素(3-34).牛组(P < 0.05),钙尔奇组拉伸与弯曲实验各项力学性能指标与模型组差异无显著性意义(P > 0.05);仙灵骨葆胶囊组大鼠股骨最大载荷、最大位移、最大应变、最大应力与正常对照组差异无显著性意义(P > 0.05);②胫骨弯曲实验:模型组大鼠胫骨弯曲实验最大载荷、最大应力、最大弯矩、最大应变、抗弯截面模量均显著低于正常对照组、仙灵骨葆胶囊组、阿仑膦酸钠组、甲状旁腺激素(3-34).牛组(P < 0.05),钙尔奇组各项弯曲力学性能指标与模型组差异无显著性意义(P > 0.05);仙灵骨葆胶囊组大鼠各项弯曲力学性能指标与正常对照组差异无显著性意义(P > 0.05);③综上,模型组大鼠因骨质疏松导致股骨的压缩、胫骨的弯曲力学特性发生了改变。骨质疏松大鼠模型以仙灵骨葆胶囊、阿仑膦酸钠、甲状旁腺激素(3-34).牛干预治疗后,股骨的压缩、胫骨的弯曲力学特性均有一定恢复,以仙灵骨葆胶囊干预治疗组的效果最为显著。

Abstract:

BACKGROUND: The effect of Xianling Gubao Capsule for the elderly female osteoporotic animal models assessed by compression and bending mechanical properties is little reported.
OBJECTIVE: To investigate the curative efficacy of Xianling Gubao Capsule, alendronate sodium, calcium carbonate and parathyroid hormone (3-34) for an osteoporotic rat model through compressive and bending tests at the femur.
METHODS: The rat models of osteoporosis were established by bilateral ovariectomy, and were then subjected to the treatment of Xianling Gubao Capsule, alendronate sodium, calcium carbonate and parathyroid hormone (3-34), respectively, for 20 weeks. Afterwards, the rats were killed by cutting the abdominal aorta, and then the bilateral femurs were removed to undergo compressive and bending tests. 
RESULTS AND CONCLUSION: The compressive test: the elastic stress, elastic load, elastic strain, elastic displacement, maximum load, maximum strain, maximum stress, maximum displacement and elastic modulus in the model group were significantly lower than those in the blank control, Xianling Gubao Capsule, alendronate sodium and parathyroid hormone (3-34) groups (P < 0.05). The maximum load, maximum strain, maximum stress, and maximum displacement did not differ significantly between Xianling Gubao Capsule and blank control groups (P > 0.05). All indexes in the compressive and bending tests showed no significant differences between model and calcium carbonate groups (P > 0.05). Bending test: the maximum load, maximum stress, maximum strain, maximum bending moment and bending section modulus in the model group were significantly lower than those in the blank control, Xianling Gubao Capsule, alendronate sodium and parathyroid hormone (3-34) groups (P < 0.05). The bending mechanical indexes showed no significant differences between Xianling Gubao Capsule and blank control groups (P > 0.05). To conclude, after compressive and bending tests, Xianling Gubao Capsule, alendronate sodium, and parathyroid hormone (3-34) all restore the mechanical properties of the femur, and Xianling Gubao Capsule obtains a significant curative efficacy.
