摘要:

《2023年中国退行性脊柱健康报告》提到35岁以下患者的腰椎手术比例近年来显著增加,颈、腰椎病有年轻化的趋势。腰椎间盘突出症成为最困扰大众的疾病之一,研究椎间盘退变的发病机制和治疗方法有着重要的临床意义。目前人类椎间盘相关疾病多采用影像学诊断,由于脊柱的组织样本不易得到,实验动物以成本低、周期短、易获取的优点,成为替代性研究对象。人与其他动物的椎间盘有着结构和生理上的差异,比较人与其他动物的椎间盘结构和病理生理特点是研究的基础和关键。本文综述了不同动物椎间盘解剖与组织学结构相关研究文献并进行比较分析,分别从椎间盘的高度、椎间盘的几何形状、腰椎间盘软骨终板特征、椎间盘内细胞外基质组分4个角度比较了不同动物的椎间盘特点。分析结果表明:人类、袋鼠、绵羊、猪、大鼠在第六颈椎至第七颈椎处的椎间盘相对高度数值最接近;与人类腰部椎间盘几何形状最为相似的是小鼠腰椎间盘;与其他动物相比,人类的软骨终板最厚,细胞密度最小;猪纤维环内部的胶原蛋白与人类的差异最大,但猪、绵羊、兔、大鼠的髓核含水量与人类相比无差异性。在此基础上,本文还阐述了人与其他动物之间椎间盘退变的共性和差异表现,也对不同实验动物椎间盘退变的造模方法进行了总结,旨在为椎间盘退变研究选择合适的实验动物模型提供基础数据。

Abstract:

The 2023 China Health Report on Spine Degeneration noted a significant increase in lumbar surgery among patients under 35 years old in recent years, indicating a trend towards younger onset of cervical and lumbar diseases. Lumbar intervertebral disc herniation has become a major concern, making the study of disc degeneration pathogenesis and treatment methods clinically significant. At present, human intervertebral disc diseases are primarily diagnosed through imaging due to the challenges of obtaining tissue samples from the spine. Therefore, experimental animals have emerged as alternative research subjects because they are cost-effective, have short experimental cycles, and are easily accessible. Given the structural and physiological differences between human and other animal intervertebral discs, comparing their anatomy and histological characteristics forms the foundation of research into human disc degeneration. The purpose of this paper is to collect and review relevant studies on anatomical and histological structures of intervertebral discs in different animals and conduct a comparative analysis from four aspects, namely, intervertebral disc height, lumbar disc geometry, lumbar disc cartilaginous endplate characteristics, and extracellular matrix components. The results show that humans, kangaroos, sheep, pigs, and rats exhibit similar relative heights between the sixth and seventh cervical vertebrae. Mice possess lumbar disc geometries most akin to humans. Compared to other animals, humans have the thickest cartilaginous endplates and the lowest cell densities. The collagen within the fibrous annulus differs most notably in pigs compared to humans, while water content in the nucleus pulposus is consistent across pigs, sheep, rabbits, rats, and humans. Additionally, this paper describes the commonalities and discrepancies in disc degeneration manifestations between humans and animals, and summarizes modeling methods for disc degeneration in different experimental animals. Ultimately, the aims of this paper is to provide fundamental data for selecting suitable experimental animal models for the study of intervertebral disc degeneration.
