Effects of Jianwei Shoutai Pills (减味寿胎丸) on Treg/Th17 Cells Balancing in Abortion Model Rats
(减味寿胎丸, JSP) in the treatment of spontaneous abortion (SA).
Methods
2
Healthy SD pregnant rats were randomly divided into blank group (n=9), model group (n=10), dydrogesterone group (n=10), and JSP group (n=10). Except for the blank group, pregnant rats in other groups were given 1.2 mg/ml mifepristone solution (10 ml/kg) by gavage on the 13th day of pregnancy to establish the SA model. During the 1st day to 14th day of pregnancy, 1.8 g/(kg·d) of JSP solution and 54 mg/(kg·d) of dydrogesterone solution were given by gavage to the corresponding groups, respectively, while 10 ml/kg of 0.5% sodium carboxymethyl cellulose solution were given by gavage to the blank group and model group. The abortion rate was calculated by observing the rats embryos. Flow cytometry was used to detect the percen-tage of whole blood regulatory T cells (Treg) and T helper 17 (Th17) cells in the CD4
+
T cells. ELISA method was used to detect the contents of serum transforming growth factor β (TGF-β), interleukin 10 (IL-10), interleukin 6 (IL-6) and interleukin 17 (IL-17).
Results
2
Compared to the blank group, the model group had higher abortion rate, decreased percentage of whole blood Treg cells in the CD4
+
T cells, increased percentage of Th17 cells in CD4
+
T cells, lower levels of serum TGF-β and IL-10, and higher levels of IL-6 and IL-17 (
P
<0.05). Compared to those in the model group, the abortion rates in the dydrogesterone group and the JSP group were significantly reduced; the percentage of whole blood Treg cells in the CD4
+
T cells in the JSP group increased, while the percentage of Th17 cells in the CD4
+
T cells decreased; the serum IL-6 content in dydrogesterone group decreased, while the serum TGF-β and IL-10 content in JSP group increased, and the IL-17 and IL-6 content decreased (
P
<0.05). There were no significant differences between the dydrogesterone group and JSP group in all outcomes (
P
>0.05).
Conclusion
2
JSP can reduce the abortion rate of mifepristone-induced SA rats, possibly through correcting the imbalance of Treg/Th17 cells.
