Sumario:BACKGROUND: Subclinical hypothyroidism (SH) is common during pregnancy. It is not clear whether decidual cells in SH undergo pyroptosis during pregnancy. This study aimed to investigate the possible mechanism of Bushen Antai recipe (BAR) in the treatment of SH in early pregnancy and the relationship between SH during pregnancy and decidual cell pyroptosis through a rat model. METHODS: A total of 60 female rats were divided into control group, model group, levothyroxine (L-T4) group, low-dose BAR group (6 g/kg), medium-dose BAR group (12 g/kg), and high-dose BAR group (24 g/kg). The control group underwent pseudothyroidectomy, while the remaining groups established nonpregnant SH rat models. Except for the blank control group, rats were successfully established with SH models during pregnancy. The control group and the model group were treated with saline or BAR. The animals were sacrificed 12 hours after the last administration. The levels of serum thyroid-stimulating hormone (TSH), free thyroxine (FT4), interleukin-1β (IL-1β), and interleukin-18 (IL-18) were detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expression of decidual nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome, Caspase-1, and porin family proteins. RESULTS: There was no significant difference in serum FT4 among groups (P>0.05). Compared with the control group, serum TSH, IL-1β, IL-18, and NLRP3, Caspase-1, and gasdermin D (GSDMD) proteins in the decidua of the model group were significantly increased (P<0.05). Compared with the model group, the L-T4 group and the high-dose BAR group could significantly decrease the levels of serum TSH, IL-1β, IL-18, and NLRP3, Caspase-1, and GSDMD in decidual tissue (P<0.05). The medium dose of BAR could significantly decrease the levels of TSH, NLRP3, Caspase-1, and GSDMD (P<0.05), and the low dose group of BAR significantly decreased the levels of TSH, NLRP3, and GSDMD (P<0.05). Among them, the high-dose group of BAR had the best reducing effect on IL-18, NLRP3, Caspase-1, and GSDMD. CONCLUSIONS: The decidual cells of SH rats in early pregnancy underwent pyroptosis with a high inflammatory response. BAR could improve TSH level in SH during pregnancy, inhibit decidual cell pyroptosis, and reduce the expression of inflammatory factors.
