摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗分析血管内皮生长因子(vascular endothelial growth factor,VEGF)、微小RNA18a(microRNA18a,miR18a)、微小染色体维持蛋白7(minichromosome maintenance 7,MCM7)在子宫肌瘤组织中的表达及其临床意义。
〖HTH〗方法〖HTSS〗〖KG*2〗通过免疫组织化学法测定43例子宫肌瘤组织和瘤旁组织中的VEGF、MCM7、孕激素受体(progesterone receptor,PR)及雌激素受体(estrogen receptor,ER)的表达,通过原位杂交法测定miR18a的表达,并对表达结果进行比较分析。
〖HTH〗结果〖HTSS〗〖KG*2〗VEGF、MCM7、PR、ER在子宫肌瘤组织中的阳性率明显高于正常子宫肌组织,而miR18a阳性率明显低于正常子宫肌组织(P<005);Spearman相关分析结果显示,PR、ER与VEGF、MCM7均呈明显正相关(P<005),与miR18a呈明显负相关(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗在子宫肌瘤组织中VEGF、MCM7均呈高表达,miR18a呈低表达,与子宫肌瘤发生发展密切相关。

Abstract: [Abstract] Objective〖HTSS〗〓To analyze the expression and clinical significance of vascular endothelial growth factor(VEGF), microRNA18a(miR18a) and minichromosome maintenance 7(MCM7) in uterus myoma tissues.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The expression of VEGF, progesterone receptor (PR), estrogen receptor (ER) and MCM7 of 43 uterus myoma tissues and perimyoma normal tissues were detected by immunohistochemistry,the expression of miR18a were detected by in situ hybridization method.The expression results were compared and analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The positive rates of  VEGF, PR, ER and MCM7 in uterus myoma tissues were significantly higher than those in perimyoma normal tissues,the positive rates of miR18a was significantly lower than those in perimyoma normal tissues(P<0.05). The results of Spearman correlation analysis showed,the expression of PR,ER were positively correlated with the expression of VEGF, and MCM7(P<0.05) were positively correlated with the expression of miR18a(P<0.05).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓There are high expression of VEGF, MCM7 in uterus myoma,the expression of miR18a is low,It is closely related with the occurrence and development of myoma of uterus.
