Besides aging, weight bearing is probably a key factor of the increase of anulus fibrosus cells apoptosis.

除衰老外，负重可能是纤维环细胞凋亡增加的关键因素。

In the control group, fibrous anulus was intact.

对照组保持纤维环完整。

Summary of Background Data. Tears are evidence of structural failure involving the anulus .

数据信息概要：裂隙是包括纤维环在内结构失效的证据。

The progressive damage appears to develop with a small cleft inside the first inner layer of the anulus.

损伤的进展看似由纤维环最内第一层产生的小裂口开始。

Flash impetus and adopting projection anulus controlling upsetting, steady speed flash and quality of butt welding point is well.

闪光推进和顶锻采用凸轮控制，闪光速度平稳对接焊口质量好。

Judging by operative and pathological findings to discuss the Gd-DTPA enhancement of the fragment herniation and the signs of disrupted anulus fibrosis.

依手术及病理发现探讨髓核突出增强原理及纤维环破裂的依据。

Objective. This study investigated whether extension or combined extension and side flexion could move the displaced portion of nucleus from the anulus towards the nucleus.

目的：本实验旨在研究伸展或联合伸展及侧方屈曲是否能使纤维环的突出部分向髓核方向移动。

Concerning anulus failures such as fissures and disc prolapses, the mechanical response of the intervertebral disc during combined load situations is still not well understood.

关于像脑裂和椎间盘突出时的环纤维，椎间盘在联合负荷状态下的反应机制目前尚不清楚。

Conclusions: Besides aging, weight bearing is probably a key factor of the increase of anulus fibrosus cells apoptosis and the degeneration of annulus fibrosus of intervertebral disc.

结论：除增龄外，负重是增加纤维环细胞凋亡、加重椎间盘纤维环破损和退变的重要因素。

Conclusions Anulus fibrosus cells isolated from nondegenerative intervertebral discs can differentiate into adipocytes, osteoblasts, chondrocytes, neurons, and endothelial cells in vitro.

结论：从未退变的椎间盘分离的纤维环细胞能在体外分化为脂肪细胞、格根包尔氏细胞、软骨细胞、神经元及内皮细胞。
