目的:通过检测LEASO患者血清中sVCAM-1的表达水平探讨sVACM-1在LEASO中的临床诊断价值。方法:纳入82例自2023年12月至2024年7月在青岛市市立医院就诊并确诊为LEASO的患者(将其定义为下肢动脉硬化闭塞症组(LEASO组),并根据病变部位及Fontaine分期将其分组。随机纳入同期40名来我院体检的健康者,定义为健康对照组。用酶联免疫吸附法(ELISA)检测各组患者血清sVCAM-1的表达量,计算各组间sVCAM-1表达水平差异;将sVCAM-1与实验室检查结果进行LEASO的影响因素logistic回归分析;并用sVCAM-1联合实验室检查指标对LEASO进行诊断预测。结果:LEASO患者组sVCAM-1表达量高于健康对照组(P 0.05)。而在根据病变涉及的下肢血管部位的分组中,膝上动脉病变组sVCAM-1的表达量最高,且膝上膝下动脉病变合并组sVCAM-1的表达量高于膝下动脉病变组(P Objective: To explore the clinical diagnostic value of sVACM-1 in LEASO by detecting the expression level of sVCAM-1 in serum of LEASO patients. Methods: Eighty-two patients who visited Qingdao Municipal Hospital from December 2023 to July 2024 and were diagnosed with LEASO (defined as the lower extremity atherosclerotic occlusive disease group (LEASO group)) were included and grouped according to the lesion site and Fontaine staging. Forty healthy individuals who came to our hospital for physical examination during the same period were randomly included and defined as the healthy control group. The expression of serum sVCAM-1 was detected by enzyme-linked immunosorbent assay (ELISA) in each group of patients, and the difference of sVCAM-1 expression level between the groups was calculated;logistic regression analysis of the influencing factors of LEASO was carried out by combining sVCAM-1 with the laboratory examination results;and diagnostic prediction of LEASO was carried out by using sVCAM-1 in combination with laboratory examination indexes. Results: The expression of sVCAM-1 in the LEASO patient group was higher than that in the healthy control group (P 0.05). In contrast, in the grouping according to the vascular site of the lower limb involved in the lesion, the expression of sVCAM-1 was highest in the supra-knee artery lesion group, and the expression of sVCAM-1 in the combined supra-knee infra-knee artery lesion group was higher than that of the infra-knee artery lesion group (P < 0.05). sVCAM-1 expression was also progressively higher with the elev
