摘要
目的观察达那唑预处理后子宫内膜的病理变化,及表皮生长因子受体(EGFR)与血管内皮生长因子(VEGF)的表达情况 .方法选择无排卵性功能失调性子宫出血患者60例,达那唑组(30例)应用达那唑预处理后行子宫内膜电切术(TCRE),对照组(30例)直接行TCRE术.切除内膜用HE染色观察内膜腺体数量、间质的疏松度,测定EGFR及VEGF表达情况.结果达那唑预处理组子宫内膜绝大部分处于增生期(类似于增生早期),近基底层腺体的数目比对照组明显减少(P<0.05),间质疏松度(+～++)较对照组(++～+++)明显致密(P<0.05);两组EGFR及VEGF在腺体中的表达强度及表达率均大于间质(P<0.05),达那唑可明显降低内膜中EGFR及VEGF的表达强度及表达率(P<0.05).结论达那唑预处理子宫内膜后,可使内膜的生长明显受到抑制,内膜变薄,腺体减少,间质致密;达那唑预处理后腺体和间质中EGFR及VEGF的表达降低.
Objective To study the expressions of EGFR and VEGF in endometrium after danazol pretreatment and the pathological changes of endometrium. Methods A total of 60 patients with anovulartory functional bleeding were randomly divided into two groups: Danazol group and control group with 30 cases in each group. Danazol group were given transcervical resection of endometrium with danazol pretreatment, and control group without any pretreatment. The endometrium resected from uterus was sent for histological assessment, observation of the grandular quantity and stromal loose degree, and of the expressions of EGFR and VEGF in endometrium. Results The endometrium of patients who took Danazol were almost in proliferative phase(similar to early proliferative phase).The numbers of endometrial glands near the basal layer with Danazol pretreatment were lower than that in the control group; the stromal components (+～) were more compact than the contral group (～). The expression intensity and rates of EGFR and VEGF in glands were higher than those of stromal components. Danazol decreased the expression of EGFR and VEGF in endometrium compared to the control group. Conclusion Pretreatment with Danazol can suppress the prolifieration of endometrial cells, thin the endometrium,and disperse the glands, compact the stromal components, and it can also reduce the expressions of EGFR and VEGF in endometrial glands and stromal components compared with the control group.
