结论
2
庞氏安胎止血汤通过调控p38 MAPK信号通路,调节Th1/Th2平衡,从而实现保胎作用。
Objective
2
To explore the anti-abortional effect of Pangshi Antai Zhixue decoction and its mechanism in helper T lymphocyte 1 (Th1)/Th2 balance in the decidual tissues of spontaneous abortion rats with heat syndrome, based on the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway.
Method
2
Aconiti Lateralis Radix Praeparata, Zingiberis Rhizoma, and Cinnamomi Cortex decoction was used to replicate the rat model of spontaneous abortion with heat syndrome. The spontaneous abortion rats with heat syndrome were randomly divided into model group, aspirin group (5.25 mg·kg
-1
), dydrogesterone group (3.02 mg·kg
-1
), Pangshi Antai Zhixue decoction high-dose (44 g·kg
-1
), medium-dose (22 g·kg
-1
), and low-dose (11 g·kg
-1
) groups, with ten rats in each group. Ten normal rats were divided into a normal group. Rats in each group were given corresponding drugs, Once a day for 12 d. After 24 h of the last administration, blood was collected from the abdominal aorta. The enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of
β-
human chorionic gonadotropin (
β
-HCG), progesterone (P), estradiol (E
2
),
γ
interferon
(IFN-
γ
), and interleukin-4 (IL-4) in rat serum. The uterus and meconium tissues of rats were collected to determine the number and rate of miscarriages. Western blot was used to detect GATA3, T-bet, p38 MAPK, and its phosphorylation in the decidual tissue.
Result
2
As compared with the normal group, the number of live births, the
β
-HCG, P, E
2
, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the model group were reduced (
P
<
0.01), whereas the number and rate of miscarriages, IFN-
γ
in the serum, and the expression of p-p38 MAPK and T-bet protein levels in the demolded tissues increased (
P
<
0.01). As compared with the model group, the number of live births, the
β
-HCG, P, E
2
, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the Pangshi Antai Zhixue decoction medium-dose group increased (
P
<
0.01), whereas the number and rate of miscarriages, IFN-
γ
in the serum, and the expression of p-p38 and T-bet protein levels in the demolded tissues reduced (
P
<
0.01). As compared with the aspirin group, the P, E
2
, and IL-4 in the serum of rats in the dydrogesterone group and the Pangshi Antai Zhixue decoction high-dose and medium-dose groups increased (
P
<
0.01), the number of live births in the Pangshi Antai Zhixue decoction medium-dose group increased (
P
<
0.01), and the
β
-HCG and IFN-
γ
in the serum of rats in the dydrogesterone group decreased (
P
<
0.01). The number and rate of miscarriages, IFN-
γ
in the serum, and T-bet and GATA3 levels in the decidual tissues of rats in the Pangshi Antai Zhixue decoction medium-dose group decreased (
P
<
0.05). Compared with the Pangshi Antai Zhixue decoction medium-dose group, the low-dose group, high-dose group, and dydrogesterone group showed increased number and rate of miscarriages (
P
<
0.05), and the high-dose group and dydrogesterone group decreased the number of live birth (
P
<
0.01). The IFN-
γ
in the serum and p-p38 MAPK and T-bet protein in the decidual tissue in the low-dose group, and the p-p38 MAPK and T-bet protein in the decidual tissue in the high-dose group all increased (
P
<
0.05). The
β
-HCG, P, and E
2
in the serum of rats in the Pangshi Antai Zhixue decoction low-dose group, dydrogesterone group, and aspirin group decreased (
P
<
0.01), and the IL-4 in the serum and GATA3 in the decidual tissue of rats in the Pangshi Antai Zhixue decoction low-dose and high-dose group and the dydrogesterone group decreased (
P
<
0.01).
Conclusion
2
Pangshi Antai Zhixue decoction realizes the effect of fetal protection by regulating the activation of p38 MAPK signal pathways and Th1/Th2 balance.
