Abstract

Abstract:

Objective To investigate the therapeutic efficacy of intrauterine perfusion with sodium hyaluronate hydrogel loaded with luteolin in a rat model of intrauterine adhesion (IUA). Methods Fifty specific pathogen free (SPF)-level SD rats were randomly assigned to five experimental groups: the normal control group (group A), the IUA model group (group B), the sodium hyaluronate hydrogel treatment IUA group (group C), the luteolin solution treatment IUA group (group D) and the sodium hyaluronate hydrogel loaded with luteolin treatment IUA group (group E), with 10 rats in each group. Except for the group A, which only received gas anesthesia, IUA model was established in all other groups using a 95% ethanol injection method. One week after modeling, rats in the groups B, C, D and E received intrauterine injection of normal saline, sodium hyaluronate hydrogel, 10 g/L luteoloside solution and sodium hyaluronate hydrogel loaded with 10 g/L luteoloside, respectively. Following a 7-day intervention period, protein expression levels of matrix metalloproteinase-9 (MMP-9), transforming growth factor-β1 (TGF-β1), Vimentin, collagen type Ⅴ alpha 2 chain (COL5A2) and collagen type I alpha 1 chain (COL1A1) in endometrial tissue were assessed by Western blot analysis. Serum concentrations of interleukin-6 (IL-6) and IL-8 were measured using enzyme-linked immunosorbent assays (ELISA). Two weeks post-intervention, the number of gestational sacs was recorded following pregnancy induction. Results Compared with the group A, the expression levels of TGF-β1, vimentin, COL5A2, COL1A1, IL-6 and IL-8 were increased, MMP-9 protein expression was decreased and the number of gestational sacs was reduced in the groups B, C, D and E (P < 0.05). Compared with the group B, expression levels of TGF-β1, vimentin, COL5A2, COL1A1, IL-6 and IL-8 decreased, MMP-9 protein expression increased and number of gestational sacs increased in the groups C, D and E (P < 0.05). These changes were more pronounced in the group E. Conclusion Intrauterine perfusion of sodium hyaluronate hydrogel loaded with luteoloside effectively alleviates intrauterine adhesions, suppresses inflammatory responses and enhances reproductive outcomes in the rat IUA model, demonstrating superior therapeutic efficacy compared to monotherapy approaches.
