概括
使用突液葡萄糖,乳酸和乳酸脱酶 (LDH) 的新复合评分显示出用于诊断败血性关节炎 (SA) 的希望. 这一分数有助于快速排除SA,提高诊断效率.
科学领域:
- 生物化学 生物化学
- 整形外科 整形外科 整形外科
- 传染性疾病 传染性疾病
背景情况:
- 败血性关节炎 (SA) 是一种关节感染,需要及时诊断.
- 精确区分SA和其他关节疾病,如结晶相关关节炎 (C-rA),至关重要.
研究的目的:
- 评估突液 (SF) 生物化学标记物,用于诊断SA.
- 评估结合SF标记物测量用于SA识别的复合得分的有用性.
主要方法:
- 来自接受关节切除术的患者的阴道液分析了葡萄糖,乳酸脱酶 (LDH) 和乳酸水平.
- 使用接收器操作特征 (ROC) 曲线分析开发了一个复合得分,以确定每个生物标志物的最佳值.
- 综合得分的诊断性能在初始和验证队列中进行了评估.
主要成果:
- 与非SA和C-rA相比,在SA观察到较低的SF葡萄糖和较高的乳酸盐和LDH水平.
- 综合得分包括葡萄糖,乳酸和LDH,在初始队列中,SA在≥3的值下显示出高灵敏度 (100%) 和特异性 (73.9%).
- 一个较高的值 (≥5) 产生了55.5%的灵敏度和97.8%的特异性,在验证队列中得到一致的结果.
结论:

01:16Structural Joints: Synovial Joints
6.3K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...
