摘要
目的探讨颈动脉狭窄患者血清中血管内皮生长因子(VEGF)的变化及临床意义。方法采用双抗体夹心酶联免疫吸附试验法检测72例颈动脉狭窄患者(病例组)和30例体检者(对照组)血清中VEGF水平。将病例组患者根据颈动脉狭窄程度分为A组(颈动脉狭窄〈50%,23例)、B组(50%≤颈动脉狭窄〈75%,30例)、C组(颈动脉狭窄975%,19例),并进行比较。分析发生颈动脉狭窄的危险因素。结果病例组高血压、高血脂、糖尿病发生率显著高于对照组[69.44%(50/72)比36.67%(11,30)、63.89%(46/72)比43.33%(13/30)、50.00%(36,72)比23.33%(7,30)],差异有统计学意义(P〈0.05)。对照组、A组、B组、C组血清VEGF水平分别为(0.59±0.20)、(.91±0.30)、(2.96±0.99)、(5.87±1.96)ng/L,与对照组比较,A、B、c组血清VEGF水平显著上升,差异有统计学意义(t=4.147、8.746、5.332,P〈0.05);A、B、C组之间血清VEGF水平差异较大,其检测结果为C组〉B组〉A组,各组之间比较差异有统计学意义(F=27.683,P〈0.05)。颈动脉狭窄程度与血清VEGF水平呈正相关(r:0.875,P〈0.05)。结论VEGF在颈动脉狭窄患者血清中呈高表达,血清VEGF高水平可能成为颈动脉狭窄发生和发展的危险因素之一。
Objective To study the changes and clinical significance of vascular endothelial growth factor (VEGF) in serum of patients with carotid artery stenosis (CAS). Methods The serum VEGF level of 72 CAS patients (CAS group) and 30 normal persons (control group) were detected by double antibody sandwich enzyme linked immunosorbent assay(ELISA). The patients in CAS group were divided into A group (CAS 〈50%,23 cases),B group (50% 〈~CAS 〈75%,30 cases)and C group (CAS≥75%,19 cases) according to the degree of CAS. The risk factors of CAS were analyzed. Results The incidence of hypertension, hyperlipidemia, diabetes in CAS group were significantly higher than those in control group [ 69.44% (50/72) vs. 36.67%(11/30) ,63.89% (46/72) vs. 43.33% (13/30) ,50.00% (36/72) vs. 23.33% (7/30) ] (P 〈 0.05). The serum VEGF level in control group, A group, B group and C group were (0.59 ± 0.20), (0.91 ± 0.30), (2.96 ± 0.99) and (5.87 ±1.96) ng/L,respectively. Compared with those in control group,the serum VEGF level in A, B, C group increased significantly (t = 4.147,8.746,5.332,P 〈 0.05). The serum VEGF level among A, B, C group had statistical difference: C group 〉 B group 〉 A group (F = 27.683, P 〈 0.05 ). The serum VEGF level and the carotid stenosis degree had significantly positive correlation (r = 0.875, P 〈 0.05 ). Conclusions The serum VEGF level has high expression in patients with CAS. The high level of serum VEGF may be one of the risk factors of the occurrence and development of CAS.
