The expression of c-erbB2 was detected immunohistochemically by monoclonal antibody against the gene on the formalin-fixed paraffin sections of 21 hydatidiform moles, 21 invasive moles, 20 choriocarcinomas and 30 normal placentas. Results showed that the expression level of c-erbB2 was significantly higher in gestational trophoblastic tumor than in hydatidiform mole and normal placenta of midterm and term pregnancy (P<0.05), while there was no significant difference between patients with gestational trophoblastic tumor of stage Ⅲ, Ⅳ and those of stage Ⅰ, Ⅱ. It was demonstrated that overexpression of c-erbB2 may closely associated with malignant transformation of hydatidiform mole, not only providing important insight into pathogenesis of gestational trophoblastic tumor, but also having an important significance for the early diagnosis and early treatment of gestational trophoblastic tumor.展开更多
背景:近几年有很多关于外泌体非编码RNA与妊娠期糖尿病发生机制的研究,但缺乏不同来源尤其是胎盘来源外泌体的最新系统综述。目的:文章对微小RNA、长链非编码RNA和环状RNA以及外泌体在妊娠期糖尿病中的变化情况及对疾病发生发展的可能...背景:近几年有很多关于外泌体非编码RNA与妊娠期糖尿病发生机制的研究,但缺乏不同来源尤其是胎盘来源外泌体的最新系统综述。目的:文章对微小RNA、长链非编码RNA和环状RNA以及外泌体在妊娠期糖尿病中的变化情况及对疾病发生发展的可能作用进行综述,为临床妊娠期糖尿病的早期筛查与治疗提供潜在靶标。方法:从PubMed、Web of Science、中国知网、万方数据及维普数据库进行非编码RNA或外泌体非编码RNA与妊娠期糖尿病相关文献进行检索,最终纳入74篇文献进行综述。结果与结论:①非编码RNA通过调节各种生理功能参与了妊娠期糖尿病的发生发展,为妊娠期糖尿病的研究提供了新的方向。②外泌体在人体中广泛存在,红细胞、上皮细胞和胎盘细胞等均可分泌外泌体,这些不同来源外泌体中的非编码RNA被证明可以在妊娠期糖尿病的发病机制、诊断以及治疗方法中发挥一定的作用。③微小RNA与妊娠期糖尿病:外周血微小RNA在妊娠期糖尿病中的作用主要是影响滋养层细胞、胰腺β细胞功能以及妊娠期糖尿病血糖水平;胎盘微小RNA可反映妊娠期糖尿病的严重程度,并损伤滋养层细胞的功能。④长链非编码RNA与妊娠期糖尿病:外周血长链非编码RNA可以通过磷脂酰肌醇3激酶/蛋白激酶B通路诱导胰岛素抵抗并且有可能为妊娠期糖尿病的诊断与治疗提供新的思路;胎盘长链非编码RNA可以调控妊娠期糖尿病胎盘滋养层细胞增殖迁移,促进妊娠期糖尿病的发生发展。⑤环状RNA与妊娠期糖尿病:外周血和胎盘环状RNA可通过损伤胎盘滋养层细胞增殖迁移与代谢等功能诱导糖尿病的发生发展。⑥外泌体非编码RNA与妊娠期糖尿病:外周血外泌体非编码RNA可影响妊娠期糖尿病血糖水平和葡萄糖稳态,通过影响胎盘功能参与妊娠期糖尿病的发生发展。⑦非编码RNA有潜力成为妊娠期糖尿病早期诊断的标志物,此外工程化的外泌体能更好地实现妊娠期糖尿病的靶向治疗等,这些最新信息为妊娠期糖尿病的基础研究和临床转化提供了参考依据。⑧未来还需改进外周血外泌体的提取和纯化方法,并排除种族、饮食和体力活动等因素以提高结果的可重复性,而循环非编码RNA及外泌体在妊娠期糖尿病的预测和诊断中的临床应用还需要更多的前瞻性临床研究。展开更多
