Abstract

Aim

miR-141-5p expression in patients with Early Spontaneous Abortion (ESA) and its correlation with hormone levels during pregnancy were investigated.

Methods

A total of 70 pregnant women with ESA were selected as the research group, and 70 normal pregnant women who chose abortion for non-medical reasons were selected as the Con group. Serum β-HCG, Progesterone (P), and Estrogen (E2) were detected by enzyme-linked immunosorbent assay. Differentially expressed miRNAs were screened by miRNA microarray analysis. miR-141-5p expression was detected by RT-qPCR, and its correlation with serum β-HCG, P, and E2 levels was analyzed. The diagnostic value of miR-141-5p for ESA was evaluated by the ROC curve.

Results

Serum β-HCG, P, and E2 were decreased and serum miR-141-5p was increased in patients with ESA. Pearson correlation analysis showed that serum β-HCG, P, and E2 levels were negatively correlated with miR-141-5p expression levels. ROC curve showed that miR-141-5p had a diagnostic value for ESA.

Conclusions

miR-141-5p is related to hormone levels during pregnancy and is expected to become a new candidate diagnostic marker for ESA.

早期自然流产患者血清中作为生物标志物的 miR-141-5p 的表达及其临床意义。

目的：研究早期自然流产（ESA）患者体内miR-141-5p的表达及其与孕期激素水平的相关性：方法：选取70例ESA孕妇为研究组，70例非医学原因选择流产的正常孕妇为对照组。采用酶联免疫吸附法检测血清β-HCG、孕酮（P）和雌激素（E2）。通过 RT-qPCR 检测了 miR-141-5p 的表达，并分析了其与血清 β-HCG、P 和 E2 水平的相关性。用ROC曲线评估了miR-141-5p对ESA的诊断价值：结果：ESA患者的血清β-HCG、P和E2水平降低，血清miR-141-5p水平升高。皮尔逊相关分析显示，血清β-HCG、P和E2水平与miR-141-5p表达水平呈负相关。结论：miR-141-5p与妊娠期激素水平有关，有望成为ESA新的候选诊断标志物。
