目的 探讨将宫腔镜电切手术与高效孕激素治疗相联合,治疗青年女性子宫内膜癌的临床效果以及对患者生育功能的影响。方法 选取2018年5月—2020年5月我院收治的70例青年子宫内膜癌患者作为本次研究对象,根据患者入院时间单双号将患者分为对照组(n=35)和实验组(n=35),对照组患者应用高效孕激素治疗,实验组患者则在对照组的基础上联合应用宫腔镜电切术进行治疗。比较两组患者的临床疗效、再次妊娠的成功率,及血清CA125水平变化情况。结果 研究组患者在治疗后3个月的治疗有效率为94.2%,高于对照组患者治疗有效率74.2%,差异具有统计学意义(P<0.05);研究组在治疗后一年内成功受孕率91.4%高于对照组51.4%,差异具有统计学意义(P<0.05);治疗后,研究组血清CA125水平低于对照组(P<0.05)。结论 将宫腔镜电切术与高效孕激素治疗方式相结合,对治疗青年子宫内膜癌患者效果显著,能够保留患者生育功能的同时,降低血清CA125水平。

目的 探讨Meis1在人子宫内膜细胞中的表达及其受雌、孕激素调控的规律。方法 通过免疫细胞化学和western blot的方法检测雌、孕激素对体外培养的在子宫内膜基质细胞(ESC)及Ishikawa细胞中Meis1的表达及调控。结果 Meis1在ESC和Ishikawa细胞均有表达,且均表达于细胞核中;在ESC中,E2、P4和 E2＋P4三组中Meis1平均蛋白表达水平均高于对照组(P<0.05)。Meis1在E2、P4和 E2＋P4组之间的表达水平亦差异有统计学意义(P<0.05),表达强度E2＋P4组>P4组>E2组;在Ishikawa细胞中,E2、P4和 E2＋P4使Meis1表达增强,表达强度P4组>E2＋P4组>E2组,但与对照组比较无差异(P>0.05),E2、P4和 E2＋P4各组间亦无差异(P>0.05)。结论 转录因子Meis1在ESC和Ishikawa细胞中受到雌、孕激素的调控,可能在子宫内膜容受性分子网络的构建中发挥着重要的作用。

Objective To investegate the expression and regulation discipline of Meis1 in human ESC and Ishikawa cells in vitro by estrogen and progesterone stimuli. Methods Immunocytochemistry and western blot were used to detect the expression and regulation discipline of Meis1 in human normal endometrial cells. Results Meis1 expressed both in endometrial stromal cells (ESC) and in ishikawa cells, and both situ in nucleus. In ESC, the expression of Meis1 was up-regulated by E₂/P₄ and E₂＋P₄, and the up-regulated effect may be superposition by E₂＋P₄, the differences between the groups were statistically difference(P<0.05). In Ishikawa cells, western blot showed that the expression of Meis1 was up-regulated by E₂/P₄ and E₂＋P₄. The differences weren't statistically significant when compared with the control group or between themselves(P>0.05). Conclusion The expression of transcription factor Meis1 is regularly regulated by estrogen and progesterone, which may be a key role during the formation of endometrial receptivity molecular network.
