【摘要】:子宫内膜异位症(endometriosis,EMT)是生育年龄妇女的常见病和多发病,严重影响患者的生活质量,且近年来发病率明显升高趋势。其发病机制至今尚未阐明,虽治疗方法多样,但复发率高。研究发现血管生成及免疫因素在其发生发展中有着至关重要的作用,多种细胞因子参与了机体的免疫功能调节和炎症反应、血管生成过程。本实验旨在研究与EMT发生相关的细胞因子及其相互关系,为疾病的诊断、治疗提供思路。 目的: 用双抗体夹心ELISA法检测EMT患者血清和腹腔液中血管内皮生长因子(VEGF)、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)的水平,研究三者的相关性,探讨三者在EMT发病机制中的作用,以及用于临床诊断的价值。 材料与方法: 1.研究对象:选取2013年09月至2014年01月在苏州大学附属第一医院及盐城市妇幼保健院住院行腹腔镜手术治疗,术后病理证实为EMT的患者33例为EMT组(其中Ⅰ、Ⅱ期患者12例,,Ⅲ、Ⅳ期患者21例),术后病理证实为卵巢良性肿瘤的患者30例为疾病对照组,同期体检的健康女性20例为正常对照组。 2.研究方法:采用酶联免疫吸附法(ELISA)测定三组研究对象血清及腹腔液中VEGF、IL-6、IL-8的水平。实验结果采用SPSSl3.0统计软件分析,以p0.05有统计学意义。 结果: 1.EMT组患者腹腔液中VEGF (928.20±264.78pg/ml)、 IL-6(130.40±100.88pg/ml)、IL-8(127.18±99.42pg/ml)水平显著高于疾病对照组(183.83±39.86pg/ml、17.70±6.03pg/ml、20.0±5.51pg/ml),差异有显著统计学意义(p0.01)。EMT组患者血清中VEGF(192.96±56.67pg/ml)、IL-6(31.84±12.97pg/ml)、IL-8(36.30±14.99pg/ml)水平显著高于疾病对照组(100.59±35.59pg/ml、18.04±3.08pg/ml、18.71±4.85pg/ml)和正常对照组(95.68±29.85pg/ml、17.29±2.94pg/ml、16.98±4.24pg/ml),差异有显著统计学意义(p0.01)。疾病对照组患者血清中三种因子水平与正常对照组比较无明显差异(p0.05)。EMT患者腹腔液中三种因子水平明显高于血清水平,差异有显著统计学意义(p0.01)。 2.EMT组Ⅲ~Ⅳ期患者腹腔液中VEGF(1104.96±123.98pg/ml)、IL-6(192.56±71.47pg/ml)、IL-8(187.68±72.26pg/ml)水平明显高于Ⅰ~Ⅱ期(618.87±109.42pg/ml、21.61±5.20pg/ml、21.30±6.78pg/ml)及疾病对照组,差异有显著性意义(p0.01)。EMT组Ⅲ~Ⅳ期患者血清中VEGF(229.35±32.05pg/ml)、IL-6(38.95±10.67pg/ml)、IL-8(44.73±11.72pg/ml)水平明显高于Ⅰ~Ⅱ期(129.26±22.80pg/ml、19.38±4.06pg/ml、21.54±5.56pg/ml)及对照组,差异有显著性意义(p0.01)。Ⅰ~Ⅱ期患者腹腔液及血清中VEGF水平明显高于对照组(p0.05),IL-6、IL-8水平与对照组比较无明显差异(p0.05)。 3.EMT患者腹腔液中VEGF、IL-6、IL-8水平与r-AFS评分呈正相关(r=0.898、0.899、0.878,p0.01)。EMT患者血清中VEGF、IL-6、IL-8水平与r-AFS评分呈正相关(r=0.880、0.842、0.849,p0.01)。 4.EMT患者腹腔液中三种因子水平两两呈正相关(r=0.948、0.951、0.988,p0.01)。EMT患者血清中三种因子水平两两呈正相关(r=0.956、0.972、0.989,p0.01)。 5.血清中VEGF、IL-6、IL-8诊断EMT的特异性分别为64%、52%、64%;敏感性分别为87.9%、81.8%、78.9%。 结论: 1.EMT患者血清和腹腔液中的VEGF、IL-6、IL-8水平明显高于对照组,并且随着疾病的严重程度而升高,与r-AFS评分呈正相关,在EMT的发生发展中有着重要的作用。 2.EMT患者腹腔液及血清中VEGF、IL-6和IL-8水平呈正相关,提示三者在EMT的发生中有协同促进作用。 3.VEGF、IL-6、IL-8参与异位内膜新生血管形成和腹腔局部免疫调节,细胞因子的过量表达促进EMT发生,并加快病情进展。血清中三种因子检测诊断EMT时均有较高的敏感性,可作为诊断、判断其严重程度及疗效的重要指标,细胞因子的组合检测可增加敏感性。 4.抗血管生成和免疫调节治疗有望成为EMT非手术治疗的重要方法。
[Abstract]:Endometriosis (endometriosis, EMT) are women of childbearing age and multiple common diseases, serious impact on the quality of life of patients, and in recent years the incidence rate was significantly increased. Its pathogenesis has not been elucidated, although treatment methods varied, but the recurrence rate is high. The study found angiogenesis and immune factors in the the development has a crucial role in a variety of cytokines are involved in immune regulation and inflammation and angiogenesis. This experiment aims to study with the occurrence of EMT related cytokines and their relationship to disease diagnosis and treatment to provide ideas.
Objective:
Vascular endothelial growth factor were measured by double antibody sandwich ELISA in patients with EMT in peritoneal fluid and serum (VEGF), interleukin -6 (IL-6), interleukin -8 (IL-8) level of correlation between the three, and to discuss the three roles in the pathogenesis of EMT, as well as for clinical diagnosis the value.
Materials and methods:
1. research object: from 2013 09 to 2014 01 months in First Hospital Affiliated to Suzhou University and Yancheng Maternal and Child Health-Care Center hospital underwent laparoscopic surgery, postoperative pathology confirmed EMT patients with 33 cases of EMT group (I, II in 12 cases, III, IV in 21 cases), postoperative pathology confirmed benign ovarian tumor patients 30 cases of disease control group, healthy women and 20 cases of normal control group.
2., research method: enzyme linked immunosorbent assay (ELISA) was used to determine the levels of VEGF, IL-6 and IL-8 in serum and peritoneal fluid of three groups. The results of the experiment were statistically analyzed by SPSSl3.0 statistical software.
