单核细胞趋化蛋白-1在子宫内膜异位症患者子宫内膜组织中的表达

目的检测单核细胞趋化蛋白-1（MCP-1）在子宫内膜异位症(内异症)患者子宫内膜组织中的表达情况,并探讨其与内异症发病的关系。方法内异症患者30例作为研究组,非内异症患者20例作为对照组。用半定量逆转录聚合酶链反应（RT-PCR）方法检测两组子宫内膜组织中MCP-1信使核糖核酸(mRNA)的阳性表达率及相对水平。结果研究组26例(87%)内膜组织中可检测到MCP-1mRNA的表达,其中19例为强阳性表达,但其表达强度与内异症的严重程度无明显相关性。对照组15例(75%)内膜组织中可检测到MCP-1mRNA表达,仅3例为强阳性表达。研究组内膜组织中MCP-1mRNA的表达强度高于对照组(两组相对表达强度分别为0.746±0.345及0.460±0.341,P<0.05)。结论内异症患者的子宫内膜组织中MCP-1mRNA的表达增强,MCP-1对内异症的发病有一定促进作用。

Expression of monocyte chemotacticp protein-1 in the eutopic endometrium of women with endometriosis

OBJECTIVE: To examine the expression of monocyte chemotactic protein-1 (MCP-1) messenger ribonucleic acid (mRNA) in the endometrium of patients with and without endometriosis. METHODS: A reverse transcription-polymerase chain reaction (RT-PCR) method was utilized to examine and quantitate MCP-1 mRNA expressions and levels in the eutopic endometrium. Thirty patients with endometriosis were included as study group, and 20 patients without endometriosis selected as control group. RESULTS: 26 (87%) of 30 samples of endometrium from patients with endometriosis expressed MCP-1 mRNA, 19 of which were strong expression, while 15 (75%) of 20 samples of endometrium from patients without endometriosis express MCP-1 mRNA (P > 0.05). When endometriosis were grouped by Revised American Fertility Society (RAFS) stages, there was no obvious correlation between stage and MCP-1 mRNA expression level (P > 0.05). Semi-quantitative PCR showed the expression level of MCP-1 in endometrium of patients with endometriosis were higher than those of patients without endometriosis (0.746 +/- 0.345 Vs 0.460 +/- 0.341 respectively, P < 0.05). CONCLUSIONS: The MCP-1 mRNA is over expressed in the eutopic endometrium from patients with endometriosis, which may play some roles on the pathogenesis of endometriosis.
