摘　　要：目的 探讨腰椎管狭窄(LSS)患者黄韧带中成纤维细胞生长因子1(FGF-1)、血管内皮生长因子(VEGF)表达与腰椎减压术后再狭窄的关系。方法 选择138例行腰椎减压术治疗的LSS患者,分为轻度组[绝对跛行距离(ACD)≤200 m,41例]、中度组(ACD 201~400 m,67例)和重度组(ACD> 400 m,30例),另选择138例非LSS患者为对照组。检测黄韧带组织FGF-1、VEGF表达,术后随访统计再狭窄发生情况。结果 LSS组黄韧带组织中FGF-1表达低于对照组(P <0.001),VEGF表达高于对照组(P <0.001)。重度组黄韧带组织中FGF-1表达低于中度组和低度组(P <0.05),VEGF表达高于中度组和低度组(P <0.05)。LSS椎管重度狭窄、减压不彻底、VEGF高表达是LSS患者腰椎减压术后再狭窄危险因素(P <0.05,P <0.001),FGF-1是保护因素(P <0.05)。结论 LSS患者黄韧带组织中FGF-1表达降低,VEGF表达升高,且与椎管狭窄程度以及术后再狭窄有关。Objective To investigate the relationship between the expressions of fibroblast growth factor 1(FGF-1)and vascular endothelial growth factor(VEGF)in the ligamentum luteum in patients with lumbar spinal stenosis(LSS)and restenosis after decompression.Methods 138 LSS patients underwent lumbar decompression were selected,including mild group[absolute claudication distance(ACD)≤200 m,41 cases],moderate group(ACD 201~400 m,67 cases)and severe group(ACD>400 m,30 cases),and 138 non-LSS patients were selected as control group.The expressions of FGF-1 and VEGF in ligamentum flavum were detected,and the restenosis was measured after the operation.Results The expression of FGF-1 in LSS group was lower than that in control group(P<0.001),and the expression of VEGF was higher than that in control group(P<0.001).The expression of FGF-1 in severe group was lower than that in moderate and low degree groups(P<0.05),and the expression of VEGF was higher than that in moderate and low degree groups(P<0.05).Severe spinal stenosis,incomplete decom-pression and high expression of VEGF were risk factors for restenosis after lumbar decompression in patients with LSS(P<0.05,P<0.001),and FGF-1 was protective factor(P<0.05).Conclusion FGF-1 expression decreased and VEGF expression increased in ligamentum flavum of LSS patients,which was related to the degree of spinal ca-nal stenosis and postoperative restenosis.
