目的
2
探讨神经肽Y(neuropeptide Y,NPY)及其Y1受体(Y1 receptor,Y1R)在骨质疏松及骨微损伤修复过程中的作用。
方法
2
收集因骨质疏松(osteoporosis,OP)股骨颈骨折(OP组)、髋关节骨关节炎(osteoarthritis,OA)(OA组)行人工髋关节置换术的绝经后女性患者股骨头样本,通过微型计算机断层扫描(micro computed tomography,Micro-CT)扫描、碱性品红染色、免疫组化及生物力学测试,比较2组间骨质疏松骨微结构损伤累积和NPY/Y1R表达差异。建立去卵巢(ovariectomized,OVX)大鼠模型(OVX组),施加疲劳载荷后,腹腔注射Y1R特异性拮抗剂BIBO3304(OVX+BIBO3304组,简称Y1RA组)进行干预,评估其对骨质疏松及骨微损伤的改善作用。
结果
2
与OA组相比,OP组骨体积分数(bone volume/total volume,BV/TV)[(21.30±5.11)% vs. (37.52±9.05)%]、连接密度(connectivity density,Conn.D)[(2.45±0.34) mm⁻³ vs. (3.52±0.43) mm⁻³]、骨小梁数量(trabecular number,Tb.N)[(1.14±0.12) mm ⁻¹ vs. (1.29±0.06) mm ⁻¹]和骨小梁厚度(trabecular thickness,Tb.Th)[(0.19±0.03) mm vs.(0.30±0.07) mm]均明显降低(

P
<
0.05)。OP组弹性模量[(61.26±22.01) GPa vs. (126.58±38.18) GPa]、最大载荷能量[(2.79±0.85) J vs. (4.02±1.43) J]、极限载荷[(1 184.51±296.82) N vs. (2 699.28±941.99) N]和极限应力[(3.98±1.09) MPa vs. (11.09±4.26) MPa]均明显低于OA组(
P

结论
2
NPY/Y1R信号通路在骨质疏松和骨微损伤过程中被异常激活,导致骨修复重建失衡,Y1R拮抗剂可通过阻断该通路改善骨质疏松,促进骨微损伤修复。
Objective
2
To investigate the role of neuropeptide Y(NPY) and its Y1 receptor(Y1R) in the development of osteoporosis and the repair of bone microdamage.
Methods
2
Femoral head samples were collected from postmenopausal female patients who underwent artificial hip arthroplasty due to osteoporotic femoral neck fractures(OP group) or hip osteoarthritis(OA group). Micro-CT scanning,alkaline fuchsin staining,immunohistochemistry,and biomechanical tests were performed,and the two groups were compared in terms of the accumulation of osteoporotic bone microstructure damage and the expression of NPY/Y1R. An ovariectomized(OVX) rat model was established,and after fatigue load was applied,the Y1R-specific antagonist BIBO3304 was intraperitoneally injected for intervention to evaluate its effect in improving osteoporosis and bone microdamage.
Results
2
Compared with the OA group, the OP group showed significantly decreased bone volume/total volume (BV/TV)[(21.30±5.11)% vs. (37.52±9.05)%],connectivity density(Conn.D)[(2.45±0.34) mm⁻³ vs. (3.52±0.43) mm⁻³],trabecular number(Tb.N)[(1.14±0.12) mm⁻¹ vs. (1.29±0.06) mm⁻¹],and trabecular thickness(Tb.Th)[(0.19±0.03) mm vs. (0.30±0.07) mm](all
P
<
0.05),while the structure model index(SMI)[(1.86±0.26) vs. (0.97±0.37)] and trabecular separation(Tb.Sp)[(0.84±0.08) mm vs. (0.68±0.07) mm] were significantly increased(
P
<
0.05). The elastic modulus[(61.26±22.01) GPa vs. (126.58±38.18) GPa],maximum load energy[(2.79±0.85) J vs. (4.02±1.43) J],ultimate load[(1 184.51±296.82) N vs. (2 699.28±941.99) N],and ultimate stress[(3.98±1.09) MPa vs. (11.09±4.26) MPa] in the OP group were significantly lower than those in the OA group(
P
<
0.05). Immunohistochemistry showed that NPY expression[(0.40±0.08) vs. (0.31±0.09)] and Y1R expression[(0.31±0.05) vs. (0.24±0.04)] in the OP group were significantly higher than those in the OA group(
P
<
0.05). The OVX group had significantly higher microdamage microcrack density[(0.36±0.10)/mm² vs. (0.19±0.05)/mm²],length[(91.49±16.23) μm vs. (73.96±11.01) μm],and surface area density [(29.45±6.91) μm/mm² vs. (15.05±4.55) μm/mm²] compared with the Y1RA group(
P
<
0.05).
Conclusion
2
The NPY/Y1R signaling pathway is abnormally activated during the process of osteoporosis and bone micro-injury,leading to an imbalance in bone repair and reconstruction,and Y1R antagonists can improve osteoporosis and promote the repair of bone microdamage by blocking this pathway.
