目的
2
探讨减味寿胎丸治疗自然流产(SA)的可能作用机制。
方法
2
将健康SD孕鼠随机分为空白组(9只)、模型组(10只)、地屈孕酮组(10只)、减味寿胎丸组(10只)。除空白组外,其余各组孕鼠于妊娠第13天予1.2 mg/ml的米非司酮溶液灌胃(10 ml/kg)1次制备SA模型。于妊娠第0天至第14天,减味寿胎丸组和地屈孕酮组分别予减味寿胎丸溶液1.8 g/(kg·d)、地屈孕酮溶液54 mg/(kg·d)灌胃,空白组和模型组予0.5%羧甲基纤维素钠溶液10 ml/kg灌胃。观察大鼠胚胎情况计算流产率;流式细胞术检测全血调节性T细胞(Treg)、辅助性T细胞17(Th17)占CD4
+
T细胞百分比;ELISA法检测血清转化生长因子β(TGF-β)、白细胞介素10(IL-10)、白细胞介素(IL-6)、白细胞介素17(IL-17)的含量。
结果
2
与空白组比较,模型组流产率显著升高,全血Treg细胞占CD4
+
T细胞百分比下降,Th17细胞占CD4
+
T细胞百分比升高,血清TGF-β、IL-10含量下降,IL-6、IL-17含量升高(
P
<0.05);与模型组比较,地屈孕酮组和减味寿胎丸组流产率均显著下降,减味寿胎丸组全血Treg细胞占CD4
+
T细胞百分比升高、Th17细胞占CD4
+
T细胞百分比降低,地屈孕酮组血清IL-6 含量降低,减味寿胎丸组血清TGF-β、IL-10含量增加而IL-17、IL-6含量降低(
P
<0.05);地屈孕酮组与减味寿胎丸组各指标比较差异均无统计学意义(
P
>0.05)。
结论
2
减味寿胎丸可降低米非司酮所致SA模型大鼠的流产率,而纠正大鼠Treg/Th17细胞失衡可能是其作用机制之一。
Objective
2
To explore the possible mechanism of
Jianwei Shoutai Pills
(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.
