目的 探讨腰椎间盘突出症(LDH)患者手术前后血清基质金属蛋白酶-2(MMP-2)和金属蛋白酶-9(MMP-9)水平的变化及其对疼痛感知的影响.方法 选择2021年1月～2022年6月在该院接受手术的78例LDH患者作为研究组,抽取同期在该院健康体检的78例受试者作为对照组.观察两组患者血清MMP-2、MMP-9、金属蛋白酶组织抑制因子(TIMP)-1、TIMP-2水平,观察LDH患者术前、术后1个月、术后3个月时的MMP-2、MMP-9、TIMP-1、TIMP-2水平,观察患者MMP-2、MMP-9、TIMP-1、TIMP-2水平与McGill疼痛问卷(SF-MPQ)得分的相关性.结果 研究组术前MMP-2、TIMP-2水平均高于对照组(P＜0.05),两组MMP-2/TIMP-2水平差异无统计学意义(P＞0.05).研究组术前MMP-9/TIMP-1水平低于对照组,TIMP-1水平高于对照组,差异均有统计学意义(P＜0.05).术前、术后3个月时,研究组MMP-2、TIMP-2、MMP-2/TIMP-2、MMP-9、TIMP-1、MMP-9/TIMP-1水平与患者腰痛视觉模拟评分(VAS-B)、腿痛视觉模拟评分(VAS-L)、PRI、PPI评分均不存在显著相关性(P＞0.05).研究组患者术后1个月、3个月时MMP-2、TIMP-1、TIMP-2水平均高于术前(P＜0.05),术后1个月、3个月时MMP-2/TIMP-2水平和MMP-9/TIMP-1水平均低于术前(P＜0.05);研究组患者术后1个月、3个月时MMP-9水平差异无统计学意义(P＞0.05).结论 MMP-2和MMP-9水平不能解释LDH患者的疼痛及术后疼痛缓解作用,MMPs作为LDH患者疼痛治疗潜在靶点的价值应谨慎考虑.
Abstract
Objective To investigate the effect of changes in serum matrix metalloproteinase-2(MMP-2)and matrix metalloprotei-nase-9(MMP-9)levels on pain perception in patients with lumbar disc herniation(LDH)before and after surgery.Methods 78 pa-tients with LDH who underwent surgery in our hospital from January 2021 to June 2022 were selected as the study group,and 78 sub-jects who underwent physical examination in our hospital at the same time were selected as the control group.The serum levels of MMP-2,MMP-9,tissue inhibitor of metalloproteinase(TIMP)-1 and TIMP-2 were observed in the two groups.The levels of MMP-2,MMP-9,TIMP-1 and TIMP-2 were observed before operation,1 month after operation and 3 months after operation in patients with LDH.The correlation between the levels of MMP-2,MMP-9,TIMP-1,TIMP-2 and McGill Pain Questionnaire(SF-MPQ)was ob-served.Results The levels of MMP-2 and TIMP-2 in the study group were higher than those in the control group(P＜0.05),but there was no significant difference in MMP-2/TIMP-2 between the two groups(P＞0.05).The level of MMP-9/TIMP-1 in the study group(before surgery)was lower than that in the control group,and the level of TIMP-1 was higher than that in the control group,with statistical significance(P＜0.05).There was no significant correlation between the levels of MMP-2,TIMP-2,MMP-2/TIMP-2,MMP-9,TIMP-1,MMP-9/TIMP-1 and VAS-B,VAS-L,PRI,PPI of patients before and 3 months after surgery(P＞0.05).The lev-els of MMP-2 and TIMP-2 in patients with LDH at 1 month and 3 months after operation were higher than those before operation(P＜0.05),and the levels of MMP-2 and TIMP-2 at 1 month and 3 months after operation were lower than those before operation(P＜0.05).There was no significant difference in the level of MMP-9 in patients with LDH at 1 month and 3 months after operation(P＞0.05).The level of TIMP-1 at 1 month and 3 months after operation was higher than that before operation(P＜0.05),and the level of MMP-9/TIMP-1 was lower than that before operation(P＜0.05).Conclusions The levels of MMP-2 and MMP-9 can not explain the pain and its relief effect in patients with LDH.The value of MMPs as potential targets for pain treatment in patients with LDH should be carefully considered.
