文题释义:
软骨细胞:位于软骨陷窝内。幼稚的软骨细胞位于软骨组织的表层,单个分布,体积较小,呈椭圆形,长轴与软骨表面平行,越向深层的软骨细胞体积之间增大呈圆形,细胞核圆形或卵圆形,染色浅,细胞质弱嗜碱性,常见数量不一的脂滴。成熟的软骨细胞多2-8个成群分布于软骨陷窝内,这些软骨细胞由同一个母细胞分裂增殖而成,称为同源细胞群。电镜下,软骨细胞有突起和皱褶,细胞质内有大量的粗面内质网和发达的高尔基复合体及少量的线粒体。在组织切片中,软骨细胞收缩为不规则形,在软骨囊和细胞之间出现较大的腔隙。
关节退行性变:就是指随着时间的流失,年龄的增长,在人体关节处(膝关节、腰椎、颈椎关节等),尤其是关节软骨会出现轻重不同的衰退、老化、退化现象,严重的成为病变,引发骨刺演化为各种关节疾病,如膝关节炎、髋关节炎、腰椎间盘突出等,并在临床上表现为各种身体不适感,影响工作学习和生活。临床上以中老年人发病多见,特别是50-60岁的老年人,女性多于男性。
摘要
背景:
膝骨关节炎以关节及关节软骨退行性病变为主,其细胞生物学变化主要包括软骨细胞增殖和凋亡。关节软骨的再生能力较差,组织工程软骨构建对促进关节软骨缺损修复有重要意义,而细胞因子在组织构建和软骨修复中起到关键作用。
目的:对影响关节软骨损伤修复及影响软骨细胞凋亡的主要调控因子做一综述。
方法:在PubMed和万方数据库检索1999至2016年于关节软骨缺损修复、影响关节软骨损伤修复及影响软骨细胞凋亡的主要调控因子相关的中文和英文文献,对纳入的44篇文献进行归纳分析。
结果与结论:人体各种组织中的细胞因子与关节软骨损伤修复、软骨细胞凋亡及骨关节炎的病理改变有密切关系,这些细胞因子参与了软骨细胞的破坏、软骨基质的降解、滑膜的反应性炎症、骨赘形成等。关节软骨损伤后白细胞介素1β、白细胞介素6 、肿瘤坏死因子α表达升高,阻断这些促炎因子的表达可以抑制软骨损伤。胰岛素样生长因子、转化生长因子等细胞生长因子对软骨细胞增殖和基质合成有重要调节作用,多种因子通过复杂的调节路径发挥作用,参与关节软骨损伤修复和重建。

Abstract:

BACKGROUND: Knee osteoarthritis is a joint and articular cartilage degenerative disease, and its biological changes mainly include proliferation and apoptosis of chondrocytes. Articular cartilage holds poor regeneration ability, and tissue-engineered cartilage is of great significance for the articular cartilage repair, while cytokines is a major concern for this repair process.
OBJECTIVE: To overview the main regulatory factors involved in the articular cartilage repair and chondrocyte apoptosis.
METHODS: PubMed and WanFang databases were retrieved for the literature addressing articular cartilage repair and main regulatory factors involved in articular cartilage repair and chondrocyte apoptosis published from 1999 to 2016. Finally 44 eligible articles were included for analysis.
RESULTS AND CONCLUSION: Various cytokines in different human tissues are closely related to articular cartilage repair, chondrocyte apoptosis and pathological changes of osteoarthritis, which are involved in chondrocyte damage, degradation of cartilage matrix, synovial degeneration and periostosis. There is an increase in the levels of interleukin 1β and 6, and tumor necrosis factor α following articular cartilage injury. Thereafter, blocking the expression of these cytokines can protect the articular cartilage from damage. Insulin-like growth factor and transforming growth factor play an important regulatory effect on the chondrocyte proliferation and matrix synthesis. Furthermore, various cytokines regulate the articular cartilage repair and reconstruction via complicated pathways.
