摘要

This study investigates the active component Mannose-B from Codonopsis pilosula and its effect on human trophoblast cell function, particularly focusing on the regulation of Laminin Subunit Beta 1 (LAMB1) expression and its implications in subchorionic hematoma (SCH). Key genes involved in SCH pathology were identified through RNA sequencing and bioinformatics analysis. Network pharmacology was utilized to screen active components in Codonopsis pilosula and their critical targets. In vitro, HTR-8/Svneo cells were used to assess proliferation, migration, and invasion through CCK8, Transwell, and cell migration assays. A SCH rat model was established to evaluate changes in coagulation parameters, litter size, fetal viability, and fetal and placental weights. In vivo validation of Mannose-B’s effects on LAMB1 expression and SCH pathology was performed using RT-qPCR and Western Blot. Network pharmacology and molecular docking identified Mannose-B as a potentially active compound in Codonopsis pilosula, with LAMB1 as a significant predicted target. In vitro experiments suggested that Mannose-B may promote HTR-8/Svneo cell proliferation, migration, and invasion by downregulating LAMB1 expression. In vivo experiments showed a reduction in placental LAMB1 expression and partial improvement in SCH-related pathological features. Mannose-B from Codonopsis pilosula may alleviate SCH progression by modulating LAMB1 expression and enhancing trophoblast cell function. However, these findings remain preliminary and require further investigation to confirm the underlying mechanisms and clinical relevance.
