药物成份或治疗方案详述: |
本研究回顾性分析不明原因反种植失败(URIF)患者外周血自然杀伤细胞(pNKC)检查和治疗结局,根据其在外周血淋巴细胞的占比分为两组:正常pNKC组(<18%),高pNKC组(≥18%),行胚胎移植后观察两组患者的胚胎种植率、临床妊娠率、流产率及活产率,以确定不同pNKC浓度对URIF患者妊娠结局的影响。后期将两组分为口服糖皮质激素与对照组(不使用糖皮质激素),观察胚胎移植后患者的胚胎种植率、临床妊娠率、流产率及活产率,明确糖皮质激素对是否可改善URIF的妊娠结局,妊娠结局的改善是否与pNKC的浓度有关。 |

Description for medicine or protocol of treatment in detail: |
In this study, peripheral blood natural killer cells (pNKC) were examined in patients with unexplained implantation failure (uRIF). According to their proportion in peripheral blood lymphocytes, they were divided into two groups: normal pNKC group (< 18%) and high pNKC group (>= 18%). After embryo transfer, the embryo implantation rate, clinical pregnancy rate, abortion rate and live birth rate of the two groups were observed, to determine the effect of different pNKC concentrations on pregnancy outcome in uRIF patients. Later, the two groups were divided into oral glucocorticoids and control group (without glucocorticoids). The embryo implantation rate, clinical pregnancy rate, abortion rate and live birth rate of patients after embryo transfer were observed to determine whether glucocorticoids can improve the pregnancy outcome of uRIF and whether the improvement of pregnancy outcome is related to the concentration of pNKC. |
