摘要
目的探讨二至天癸颗粒对体外受精-胚胎移植(IVF-ET)周期人卵泡液中白血病抑制因子(LIF)和卵细胞质量的影响。方法入选患者随机分为两组,分别用二至天癸颗粒合西药(治疗组,42例)和单用西药(对照组,38例)治疗,观察患者取卵日肾虚证候较垂体降调节后的改善情况,比较两组获卵数、优质卵率、受精率、卵裂率、优质胚胎率、妊娠率和卵泡液LIF水平的差异;对卵泡液LIF水平与优质卵率、优质胚胎率的关系分别进行相关性检验。结果与对照组比较,治疗组肾虚证候改善程度、优质卵率、受精率、卵裂率、优质胚胎率及临床妊娠率均显著提高;卵泡液LIF水平明显高于对照组;卵泡液中LIF水平与优质卵率、优质胚胎率及妊娠结局均呈正相关。结论二至天癸颗粒能显著提高卵细胞数、胚胎质量和IVF-ET成功率,其机理与增加卵泡液LIF水平、激活卵泡微环境LIF活性充分表达有关。
Objective To investigate the effects of Erzhi Tiangui Granule (ETG) on the concentration of leukemia inhibitory factor (LIF) in follicular fluid (FF) and quality of oocytes/embryos after in vitro fertiliza- tion and embryo transfer (IVF-ET). Methods Women undergoing IVF-ET were randomly assigned to two groups: the treated group (42 cases) treated with ETG combined with Western medicine and the control group (38 cases) treated with Western medicine alone. Syndrome of Shen-deficiency, amount of oocytes, rates of ma- ture oocytes, fertilization, cleavage, high-quallty embryos and pregnancy, as well as LIF level in FF were ob- served and compared between the two groups. The relationship of LIF level with mature oocyte rate and high- quality embryo rate was analyzed, respectively. Results In the treated group after treatment, the syndrome of Shen-deficiency and the above-mentioned indexes tested were improved better than those in the control group, respectively. Correlation analysis showed that the LIF level in FF was positively correlated with the rate of ma- ture oocyte, high-quality embryo and the outcome of pregnancy. Conclusion ETG can distinctively increase the amount of oocyte, elevate the quality of embryo and raise the successful rate of IVF-ET. The mechanism maybe correlated to the increase of LIF level in FF and the activating of microenvironment for its full expression.
