摘要:

文题释义:
黄韧带肥厚:是指黄韧带组织细胞中胞外基质胶原纤维含量明显增加、弹力纤维显著减少、纤维排列紊乱的病理改变结果,其病因或发病机制尚未完全清楚,猜测可能与慢性退变、炎症、外伤、代谢障碍等因素有关,目前普遍认为黄韧带肥厚的机制是韧带在机械应力作用下导致炎症反应,随后机体产生瘢痕修复,黄韧带从而逐渐发生纤维化。
信号通路:是指在细胞中进行某种生物过程时,信号分子将信息通过细胞膜由细胞外传递到细胞内,细胞借助信号因子传递的信息,再进行一定的反馈现象。在细胞外的信号分子称之为配体,其包括了细胞因子、生长因子、激素及其他小分子化合物等等。

背景:黄韧带的肥厚纤维化被认为是造成腰椎椎管狭窄症的主要原因。近年来,多有研究报道黄韧带肥厚纤维化与多种生长因子、微小RNA及关键信号通路相关。
目的:通过细读国内外相关文献,以期为黄韧带组织肥厚纤维化分子水平及信号通路的研究进展做一系统综述。
方法:采用以下检索词:腰椎椎管狭窄症;黄韧带肥厚;黄韧带增生;黄韧带纤维化;细胞因子;蛋白;信号通路;微小RNA;lumbar spinal stenosis;hypertrophy of ligamentum flavum;ligamentum flavum hyperplasia;fibrosis of ligamentum flavum;cell factor;protein;signal path;microRNA,检索知网数据库、维普数据库、万方数据平台、PubMed数据库、Biosos Preview数据库及Web Of Science数据库,并手工检索,收集有关研究黄韧带组织肥厚纤维化的基础实验,检索时限设为建库至2020-06-30。严格按照纳入标准对所检索文献进行筛选,共纳入15篇有关的基础实验文献进行综述探讨。
结果与结论:现有的实验研究,可以发现在黄韧带组织肥厚纤维化的过程中,存在有多种生长因子及miRNA参与表达并表现出活性增加的现象,同时发现有关键信号通路参与调控黄韧带组织的纤维化过程。因此,有理由推测黄韧带增生纤维化是多种生物学过程协同参与、多维作用的共同结果;但影响的纤维化程度在目前尚未确定,未来仍需进一步行基础研究以探索验证。

Abstract:

BACKGROUND:  Ligamentum flavum hypertrophy is considered to be the main cause of lumbar spinal stenosis. In recent years, it has been reported that hypertrophy of the ligamentum flavum is related to growth factors, microRNAs and key signaling pathways.

OBJECTIVE: To make a systematic review on the molecular level and signaling pathway of hypertrophic fibrosis of the ligamentum flavum.
METHODS: Chinese and foreign databases, including CNKI, VIP, WanFang, PubMed, Biosos Preview, and Web of Science, were searched for relevant articles, and the basic experiments of hypertrophic fibrosis of the ligamentum flavum were collected by hand. The search terms included “lumbar spinal stenosis; hypertrophy of ligamentum flavum; ligamentum flavum hyperplasia; fibrosis of ligamentum flavum; cell factor; protein; signal path; microRNA” in Chinese and English, respectively. The retrieval time limit was set as June 30, 2020. The retrieved articles were screened in strict accordance with the inclusion criteria, and finally 15 relevant basic experimental articles were reviewed.
RESULTS AND CONCLUSION: In the process of hypertrophic fibrosis, the ligamentum flavum can be affected by a variety of growth factors, miRNAs and multiple signaling pathways. Therefore, it is rational to speculate that the proliferation and fibrosis of the ligamentum flavum is a consequence of multi-dimensional coordination by multiple biological processes. However, the degree of fibrosis has not been determined yet, and further basic research is still needed in the future.

Key words: ligamentum flavum, hypertrophy, fibrosis, molecular level, basic experiment, growth factor, microRNA, signaling pathway
