文题释义:
细胞因子(cytokine,CK):是免疫原、丝裂原或其他刺激剂诱导多种细胞产生的低分子量可溶性蛋白质,具有调节固有免疫和适应性免疫、血细胞生成、细胞生长以及损伤组织修复等多种功能。细胞因子可被分为白细胞介素、干扰素、肿瘤坏死因子超家族、集落刺激因子、趋化因子、生长因子等。众多细胞因子在体内通过旁分泌、自分泌或内分泌等方式发挥作用,具有多效性、重叠性、拮抗性、协同性等多种生理特性,形成了十分复杂的细胞因子调节网络,参与人体多种重要的生理功能。
ASIA神经功能分级:美国脊柱损伤协会ASIA神经功能分级:A级完全性损伤,骶段S4-S5无任何运动及感觉功能保留;B级不完全性损伤,神经平面以下,包括骶段S4-S5存在感觉功能,但无任何运动功能;C级不完全性损伤,神经平面以下有运动功能保留,一半以上的关键肌肌力< 3级;D级不完全性损伤,神经平面以下有运动功能保留,一半以上的关键肌肌力≥ 3级;E级正常,感觉和运动功能正常。
摘要
背景:
研究表明细胞因子在脊髓损伤的病理生理机制中发挥着至关重要的作用。直接或者间接的抑制或者减轻脊髓损伤后免疫炎性反应,能够改善患者的预后以及神经功能的恢复。
目的:分析颈部脊髓损伤早期(< 24 h)患者外周血中的白介素1β、白细胞介素6、白细胞介素10、肿瘤坏死因子α、转化生长因子β1和干扰素γ水平的变化与ASIA神经功能分级的相关性,并探讨细胞因子介导的免疫炎症反应在颈部脊髓损伤发病机制中的作用。
方法:30例颈部脊髓损伤患者为脊髓损伤组,另外20例健康的血液捐献者为对照组。采集外周静脉血,并使用酶联免疫吸附(ELISA法)测定外周血中细胞因子水平。脊髓损伤组依据ASIA分级分成A级10例为完全性脊髓损伤组,B级+C级+D级+E级20例为不完全性脊髓损伤组。
结果与结论:①脊髓损伤组外周血中白细胞介素1β、白细胞介素6和转化生长因子β1水平均明显高于对照组;②颈部脊髓损伤患者中完全性脊髓损伤组外周血中转化生长因子β1水平明显高于不完全性脊髓损伤组(P < 0.01);③结果说明,颈部脊髓损伤早期患者外周血中白细胞介素1β、白细胞介素6和转化生长因子β1的水平升高;颈部脊髓损伤患者外周血中转化生长因子β1水平与脊髓受损的严重程度有相关性,提示颈部脊髓损伤后患者神经系统功能缺失的程度与免疫反应之间存在着一定的联系。

Abstract:

BACKGROUND: Cytokines play a critical role in the pathophysiologic mechanism of spinal cord injury (SCI). Direct or indirect inhibition or alleviation of immune inflammatory reactions following SCI can improve the patient’s prognosis and recovery of neurologic function.
OBJECTIVE: To investigate the correlation between the levels of interleukin-1β, interleukin-6, interleukin-10, tumor necrosis factor-α, transforming growth factor-β1 and interferon-γ in the peripheral blood of patients with early cervical SCI and the American Spinal Injury Association (ASIA) impairment scale, and explore the role of cytokine-mediated immune inflammatory responses in the pathogenesis of cervical SCI.
METHODS: Thirty patients with cervical SCI and 20 healthy controls were enrolled. The levels of related cytokines in the peripheral blood were detected by ELISA. According to the ASIA impairment scale, all patients were divided into two groups: complete SCI group (Grade A, 10 cases) and incomplete SCI group (Grade B+C+D+E, 20 cases).
RESULTS AND CONCLUSION: The levels of interleukin-1β, interleukin-6 and transforming growth factor-β1 in the peripheral blood in the SCI patients were significantly higher than those in the control group. The level of transforming growth factor-β1 in the peripheral blood of the complete SCI patients was significantly higher than that of incomplete SCI patients. Our findings imply that the levels of interleukin-1β, interleukin-6 and transforming growth factor-β1 in the peripheral blood of patients with cervical SCI in early period are increased significantly, and the level of transforming growth factor-β1 is associated with the severity of SCI, suggesting that there is a correlation between dysfunction of nervous system and immune response post-cervical SCI.
