概括
在末期膝关节骨关节炎中,总超氧化物脱酶 (SOD) 活性降低. 关节液SOD活动反映了突SOD水平,这表明它可能是膝关节骨关节炎患者突炎的生物标志物.
科学领域:
- 生物化学 生物化学
- 整形外科 整形外科 整形外科
- 生物标志物 生物标志物
背景情况:
- 骨关节炎 (OA) 是一种退行性关节疾病,其特征是软骨的破坏.
- 在OA软骨中观察到总超氧化物脱酶 (SOD) 活性降低.
- 了解不同关节组织中的SOD活动对于OA管理至关重要.
研究的目的:
- 在末期膝关节OA患者的血清,关节液,软骨和突膜中评估SOD总活性.
- 确定SOD在各种组织中的活性之间的关系.
- 评估关节液SOD活动作为突炎生物标志物的潜力.
主要方法:
- 从52名末期膝关节骨质炎患者收集血清,关节液,软骨和突膜样本,这些患者接受了全膝关节整形手术.
- 在所有收集的样本中分析了SOD总活性.
- 使用斯皮尔曼等级相关性和多重线性回归来评估SOD活动之间的关系.
主要成果:
- 关节液总SOD活性与突总SOD活性呈正相关性 (β = 0.493,调整后R2 = 0.172,P < 0.01).
- 在末期膝关节OA中,关节液SOD活动更好地反映了突触性SOD活动,而不是软骨SOD活动.
- 关节液SOD和血清或软骨SOD活性之间没有发现显著的相关性.
结论:
- 关节液的总SOD活性与末期膝关节OA的突总SOD活性相关.
- 关节液SOD活动可以作为一个有价值的生物标志物,用于评估和管理膝关节OA中的突炎.
- 需要进一步的研究来探索这些发现的治疗和预防意义.

Knee Joint
1.7K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Development of the Limb Synovial Joints
1.4K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
