Study design:

Case-Control study 

研究目的:

1 探讨流产的影响因素,包括生理、心理、个人、家庭、社会、文化因素。 2 分析RSA孕妇血浆miR-21, PTEN表达情况,揭示miR-21的表达差异与RSA的发生是否存在相关性。 3 探讨“PTEN/miR-21-PTEN”致滋养细胞侵袭障碍的新途径和调控新机制。 4 探明PTEN与下游分子间的靶向关系,进一步完善miR-21-PTEN通路调控RSA滋养细胞侵袭的分子机制。 5 明确miR-21作为RSA预测与评估的分子标志物的临床应用价值,并为抗胎盘浅着床治疗RSA的药物研发提供科学依据。  

Objectives of Study:

1. Exploring the influencing factors of miscarriage, including physiological, psychological, personal, family, social, and cultural factors. 2. Analyze the expression of miR-21 and PTEN in the plasma of pregnant women with RSA, and reveal whether there is a correlation between the differential expression of miR-21 and the occurrence of RSA. 3. Explore the new pathways and regulatory mechanisms of "PTEN/miR-21-PTEN" induced invasion disorders of trophoblasts. 4. Explore the targeted relationship between PTEN and downstream molecules, and further improve the molecular mechanism of miR-21-PTEN pathway regulating RSA trophoblast invasion. 5. Clarify the clinical application value of miR-21 as a molecular marker for predicting and evaluating RSA, and provide scientific basis for drug development of anti placental superficial implantation therapy for RSA.
