目的分析血清白细胞介素-1β(IL-1β)、白细胞介素-1受体拮抗剂(IL-1Rα)、IL-1Rα/IL-1β比值在颅内外血管狭窄支架成形术后血清中的变化以及与再狭窄的关系.同时探讨IL-1β与IL-1Rα水平之间的相关性。方法选择自2008年4月至2009年3月31例在四川省人民医院神经内科接受颅内外支架成形术的颅内外动脉狭窄患者,就术前、术后1h、1d、3d、5d以及造影复查(术后6~12个月)时血清IL-1β、IL-1Rα和IL-1Rα/IL-1β比值以及血管再狭窄情况进行分析。结果本组31例患者在31根血管上放置31枚支架,随访6~12个月,6例出现了再狭窄(19.35%),超过50%的再狭窄为3例,余3例在10%~30%之间。2组患者术前IL-1β、IL—Rα、IL-1Rα/IL-1β比值差异均无统计学意义(P〉0.05),IL—1β与IL-Rα呈正相关(r=0.444,0.881;P均〈0.05);术后1h、1d、3d、5d2组患者IL-1β、IL-Rα水平均明显高于术前,差异有统计学意义(P〈0.05);术后6~12个月复查时2组IL-1β、IL-Rα水平无明显差别(P〉0.05),但再狭窄患者IL-1Rα/IL-1β比值明显低于未再狭窄患者,差异有统计学意义(P〈0.05);IL—1β与IL-R呈正相关(r=0.531,0.953;P均〈0.05)。结论血清IL-1β、IL-1Rα与支架术后的炎性过程有关,两者的免疫失调状态可能与再狭窄有关。IL-1Rα/IL-1β比值的变化可做为再狭窄监测的指标。
Objective To observe the levels of serum interleukin-1β (IL-1β) and interleukin-1 receptor antagonist (IL- 1Rα), the IL- 1Rα/IL- 1β ratio and the relationship between the levels of them and the restenosis in patients with intra- and extra-cranial arteriostenosis after stent-assisted angioplasty. Methods Thirty-one patients with cerebral artery stenosis, admitted to our hospital from April 2003 to March 2006, were treated with stent-assistant angioplasty and followed up for 6-12 months. The relationship was analyzed between the restenosis of cerebral artery and both the levels of serum IL-1β, IL-1Rα and the IL-1Rα/IL-1β ratio before and 1 h, 1, 3 and 5 d after stent-assisted angioplasty. Results The condition of 31 stents in 31 blood vessels of cerebral arteries was observed and followed up 6 to 12 months after the operation. Restenosis was noted in 6 (19.3%) with 3 restenosis superior to 50% and 3 restenosis from 10%-30%. No obvious difference of the levels of serum IL-1βand IL-1Rα, the IL-1Rα/IL-1β ratio between restenosis group and non-restenosis group before the operation was found (P〉0.05); IL-1β and IL-1Rα levels were positively correlated before the operation. The levels of serum IL-1β and IL-1Rα 1h, 1, 3 and 5 d after the operation were superior to those before the operation, respectively(P〈0.05). The levels of serum IL-1β and IL-1Rα in the restenosis group showed no significant difference to those in the non-restenosis group 6 to 12 months after the operation (P〉0.05); however, the IL-1Rα/IL-1β ratio in the restenosis group was significantly lower than that in the non-restenosis group(P〈0.05); positive correlation between the levels oflL-1β and IL-1Rα was observed. Conclusion The levels of serum IL-1β and IL-1Rα were associated with the inflammatory process after the operation and the immune maladjustment of IL-1β and IL-1Rα might be correlative to the restenosis, indicating that the IL-1Rα/IL-1β ratio might be an available index for monitoring the restenosis.
