Effects of Er'zhi Tiangui Granule (二至天癸颗粒) on Sequential Expressions of Integrin β3 and Its Ligand Osteopontin in Mouse Endometrium during Controlled Ovarian Hyperstimulation

To investigate the effects of ECzhi Tiangui Granule （二至天癸颗粒, ETG） on sequential expressions of integrin β 3 and its ligand osteopontin in the mouse endometrium during controlled ovarian hyperstimulation （COH） and implantation period. Methods： Seventy-five Mature female Kunming mice were randomly divided into 3 groups, a normal control group, a model group, and a treatment group administrated with ETG for 10 days, 25 in each group. After mated with male mice, every 5 mice were sacrified in each group at the 0, 2nd, 4th, 6th, and 8th days to take their endometrium. In-situ hybridization was used to detect the expressions of integrin β 3 and osteopontin in the endometrium. Results： mRNA expressions of integrin β 3 and osteopontin in the endometrium during implantation period showed similar time sequence rules in the treatment group to those in the normal control group; the peak values of them were a little lower in the treatment group than the normal control without significant differences. In the model group, integrin β 3 mRNA expression was higher at the 2nd day, obviously lower at the 4th and 6th days, and insignificantly lower at the 8th day; and osteopontin expression was remarkably lower at the 4th, 6th, and 8th days, compared with the normal control and the treatment groups （P〈0.05, P〈0.01）. Conclusions： COH might influence the sequential expressions of integrin β 3 and its ligand osteopontin, bring forward the integdn β 3 expression peak, impact on the cooperation of integrin β 3 and osteopontin, so as to damage the endometrial receptivity. ETG could regulate the sequential expressions of integrin β 3 and its ligand osteopontin to improve the mouse endometrial receptivity during COH.

二至天癸颗粒对体外受精周期颗粒细胞GDNF、GFRα-l表达的影响

目的:探讨二至天癸颗粒对IVF周期颗粒细胞胶质细胞源性神经营养因子(GDNF)、家族特异性受体a-1(GFRa-l)的影响,从而改善卵母细胞质量,提高妊娠率的可能机制。方法:将80例因输卵管因素行体外授精-胚胎移植(IVFET)患者分为治疗组(IVF治疗周期加用二至天癸颗粒)40例,对照组(IVF治疗周期加用安慰剂颗粒)40例。观察临床肾虚证候积分变化情况,促性腺激素(Gn)用量及用药天数,取卵数、优质卵率、受精率、优质胚胎率、临床妊娠率及颗粒细胞GDNF、GFRa-l mRNA的表达情况。结果:治疗组患者肾虚症状得到明显改善,治疗组Gn用量及用药天数低于对照组,优质卵率、优质胚胎率及临床妊娠率均高于对照组,差异均有统计学意义(P<0.05);颗粒细胞GDNF、GFRa-l mRNA表达都优于对照组,差异均有统计学意义(P<0.05)。结论:二至天癸颗粒可能通过提高颗粒细胞GDNF、GFRa-l mRNA的表达,改善卵母细胞成熟度,提高卵细胞质量,从而提高临床妊娠率。

二至天癸颗粒对不孕症患者胚胎着床期子宫内膜H19表达的影响

目的:观察二至天癸颗粒治疗肾阴虚不孕症的疗效及其对患者胚胎着床期子宫内膜H19表达的影响。方法:将70例肾阴虚不孕症患者随机分为观察组和对照组,每组各35例。观察组在超促排卵长方案基础上接受二至天癸颗粒治疗,对照组超促排卵长方案基础上接受安慰剂治疗。观察两组患者治疗前后中医证候积分变化情况,比较两组患者HCG注射日子宫相关情况、H19双等位基因表达率、生化妊娠率和临床妊娠率。结果:两组患者治疗前中医证候积分比较,差异无统计学意义(t=0.388 2,P=0.699 1);人绒毛膜促性腺激素(human chorionic gonadotropin,HCG)注射日,观察组中医证候积分显著低于对照组,差异具有统计学意义(t=4.311 7,P=0.000 1)。HCG注射日,观察组A型子宫内膜比例显著高于对照组,子宫动脉阻力指数、搏动指数显著低于对照组,差异均有统计学意义(P<0.05);两组患者子宫内膜厚度比较,差异无统计学意义(P>0.05)。观察组生化妊娠率、临床妊娠率显著高于对照组,差异有统计学意义(P<0.05)。观察组胚胎着床期子宫内膜H19双等位基因表达率显著低于对照组,差异有统计学意义(P<0.05)。结论:二至天癸颗粒治疗肾阴虚不孕症的疗效确切,并且其可以改善子宫内膜印记基因H19的表达。
