研究目的: |
1. 探索反复胚胎质差患者通过自体内膜上皮细胞共培养改善胚胎质量的可行性。 2. 通过整合代谢组学与蛋白质组学技术,系统鉴定内膜上皮细胞共培养体系中挽救胚胎质量的关键分子。探索这些关键分子的功能及其调控网络,为优化胚胎培养液配方、开发靶向干预策略提供直接的理论依据和候选分子。 |

|
Objectives of Study: |
1. Explore the feasibility of improving embryo quality in patients with recurrent poor embryo quality through co-culture with autologous endometrial epithelial cells. 2. By integrating metabolomics and proteomics technologies, systematically identify key molecules that rescue embryo quality in the endometrial epithelial cell co-culture system. Explore the functions and regulatory networks of these key molecules to provide direct theoretical foundations and candidate molecules for optimizing embryo culture medium formulations and developing targeted intervention strategies. |

随机方法(请说明由何人用什么方法产生随机序列): |
使用动态区组随机化,区组长度为2/4,医院循证医学工作室人员使用R软件生成随机数表。授精后第一天原核评分后,将患者的正常受精卵(2PN)随机分入内膜上皮细胞共培养组和常规培养组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
By employing dynamic block randomization with block sizes of 2 or 4, personnel from the hospital's Evidence-Based Medicine Studio generated a random number table using R software. On the first day post-fertilization, following pronuclear scoring, the normally fertilized oocytes (2PN) from patients were randomly allocated to either the endometrial epithelial cell co-culture group or the conventional culture group. |

盲法: |
对患者、临床医生和胚胎操作人员不设盲,对胚胎质量评分人员设盲。胚胎评估人员在不知道组别的前提下,依据照片对两组胚胎进行评分 |

Blinding: |
Patients, clinicians, and embryologists are not blinded; embryology assessors are blinded. Embryo evaluators score embryos from both groups based on photographs without knowledge of group allocation. |
