冷冻后人胚卵巢细胞团对hMG作用的内分泌与形态学反应

Zhongshan Daxue xuebao. Yixue kexue ban, 1994
妊娠２０～２４周人胚胎卵巢经改进的超速冷冻仍具有内分泌功能。这种冷冻后的胚胎卵巢细胞团体外培养时，培养无数与细胞团的Ｅ２分泌能力呈负相关，形态学检查与此结果相吻合。冷冻后人胚胎卵巢的细胞团体外培养时培养位中人绝经期促性腺激素（ｈＭＧ）最适浓度为５０ＩＵ／Ｌ，培养的最适天数为１～３ｄ。这对人胚胎卵巢细胞团同种异体移植时受体促性腺激素水平内及培养时间的选择与设定有重要指导意义。

供卵治疗卵巢早衰妊娠成功（附1例报告）

Zhongshan Daxue xuebao. Yixue kexue ban, 1995
本文报道了我国首例卵巢早衰患者采用激素替代治疗和供卵获得妊娠成功。供者采用ＧｎＲＨ－ａ／ＨＭＧ／ｈＣＧ控制的超排卵方案。受者使用类固醇激素替代治疗（ＳＣＲＴ）方案，促使子宫具备胚胎植入的条件，并与供者排卵周期同步。受者于月经周期第１７天接受经体外受精移植的胚胎５个。移植后１４天妊娠试验阳性，采用外源性激素维持妊娠直至孕１４周，于１９９４年１月１４日分娩正常的足月活男婴。本文对卵巢早衰的发病、病因、激素替代治疗，供卵的指征及成功因素进行了讨论。

超排卵全程应用225 U促黄体生成素对取卵及胚胎移植日血清血管内皮生长因子水平的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2015
【目的】 探讨促黄体生成素在控制性超排卵中降低血清血管内皮生长因子水平的有效性?【方法】 20例在超排卵全程添加225 U促黄体生成素(实验组)同50例未添加患者(对照组)比较超排卵启动日血清血管内皮生长因子水平,人绒毛膜激素注射日?取卵日及胚胎移植日血清血管内皮生长因子较启动日的升高水平?【结果】 试验组及对照组启动日血清血管内皮生长因子水平及人绒毛膜激素注射日血清血管内皮生长因子较启动日的升高水平差异不具有统计学意义;试验组取卵日(P = 0.017 ...

IVF-ET周期中单原核胚胎的形态学及体外发育潜能

Zhongshan Daxue xuebao. Yixue kexue ban, 2014
摘 要: 【目的】 探讨IVF-ET周期中单原核(1PN)胚胎形态学及继续体外培养潜能,指导其临床利用价值?【方法】 对受精后16 ~ 18 h观察到的486个1PN胚胎进行体外培养,观察其原核大小?极体及卵裂情况;通过囊胚序贯培养法将其中374个1PN胚胎培养至囊胚期,观察囊胚形成情况?【结果】 374个1PN胚胎共形成囊胚179个(47.86%),其中优质囊胚41个(22.91%)?行囊胚培养的374个1PN胚胎原核直径为(27.64 ± 3.30)μm,大于未达囊胚培养标准的81个胚胎的(26 ...
