drugs intragastrically, once a day, for 12 consecutive days. On the 13th day of pregnancy, a single intragastric administration of
mifepristone (5 mg/kg) was performed to establish a model of threatened abortion with blood heat syndrome. On the 14th day of
pregnancy, the abortion rate and uterine coefficient were calculated; the pathological morphology of pregnant uterine was observed;
the serum levels of 3,5,3′-triiodothyronine (T3), thyroid hormone (T4), thyroid stimulating hormone (TSH), as well as the
levels of vascular endothelial growth factor (VEGF) and nitric oxide (NO) in the pregnant uterus were all determined; the
expressions of mRNA and protein related to Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) and
phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathways were detected. RESULTS Compared with normal group,
the model group exhibited endometrial tissue damage, a reduced number of decidual cells, and a significant presence of blood
stasis within the uterus; abortion rate, the serum levels of T3, T4 and TSH, the mRNA expressions of JAK2, STAT3 and
suppressor of cytokine signaling 3 (SOCS3) as well as protein expressions of p-JAK2, p-STAT3 and SOCS3 in the pregnant uterus
were increased significantly (P<0.05); uterine coefficient, the levels of VEGF and NO in pregnant uterus, mRNA expressions of
VEGFR2, PI3K, AKT and endothelial nitric oxide synthase(eNOS), protein expressions of VEGFR2, PI3K and eNOS as well as
phosphorylation level of AKT in the pregnant uterus were significantly reduced (P<0.05). Compared with model group, the
endometrial tissue damage and congestion in the Qingre antai decoction group were significantly improved, and the levels of the
aforementioned quantitative indicators were significantly reversed (P<0.05). CONCLUSIONS Qingre antai decoction can improve
the pregnancy outcomes in rats with threatened abortion of blood heat syndrome, the mechanism of which may be associated with
inhibiting JAK2/STAT3 pathway and activating PI3K/AKT pathway.
