卵丘颗粒细胞的端粒长度与体外受精-胚胎移植妊娠结局的关系

目的 颗粒细胞凋亡直接影响胚胎的质量,而端粒参与了细胞增殖的调控,因此,本文探究了卵丘颗粒细胞的端粒长度与体外受精-胚胎移植妊娠结局之间的关系,为胚胎和卵母细胞的评估提供思路。 方法 选择2015年6月—2016年12月间上午入住舟山市妇幼保健院的87例进行体外受精-胚胎移植的患者作为研究对象。所有患者根据年龄,共分为4组:20～25岁(21例);26～30岁(24例);31～35岁(23例);>35岁(19例)。依据卵母细胞成熟度,将患者分为未成熟卵泡颗粒细胞组(45例)和成熟卵泡颗粒细胞组(42例);依据胚胎移植后孕囊的阴道B超检查,分为妊娠组(43例)和非妊娠组(44例)。比较患者的年龄、卵母细胞的成熟度对卵丘颗粒细胞端粒长度,分析不同成熟度的卵母细胞卵泡液内抗苗勒管激素水平以及不同妊娠结局的卵巢颗粒细胞凋亡情况。所有数据的处理分析均使用SPSS 22.0统计软件。 结果 20～25岁组、31～35岁组和>35岁组的患者颗粒细胞端粒长度和卵泡成熟度之间有明显差异,随着年龄的增加,患者体内的成熟卵母细胞的颗粒细胞的端粒长度逐渐变短,端粒的长度与年龄呈负相关(P<0.05)。未妊娠患者与已妊娠的患者之间的颗粒细胞端粒长度比较,未妊娠的患者明显更小,差异具有统计学意义(P<0.05)。未成熟卵母细胞的卵泡液内的AMH水平明显高于成熟的卵母细胞,差异具有统计学意义(P=0.007)。比较非临床妊娠组和临床妊娠组的卵巢颗粒细胞凋亡率,差异具有统计学意义(P<0.05)。 结论 端粒长度随着患者年龄的增大而缩短,未妊娠患者的端粒长度更短,卵丘颗粒细胞的端粒长度与卵母细胞的成熟度和妊娠结局密切相关,具有临床研究价值。

Effect of Patient Age and Embryo Parameters on Pregnancy Outcome in In Vitro Fertilization-Embryo Transfer （IVF-ET）

Objective To study the effect of patient age, the number and quality of embryos transferred on pregnancy outcome in in vitro fertilization-embryo transfer procedures （IVF-ETs）. Methods A retrospective study was conducted with infertile women who underwent a total of 1 800 cycles of lVF-ET and intracytoplasmic sperm injection （ICSI） at the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzhou Medical College from Jan. 2006 to Dec. 2007. The patients were divided into three groups based on age （year）. 〈30, 30-34 and 235. The rates of clinical pregnancy and multiple pregnancies were compared in each group when 1-3 embryos and 0-3 goodquality embryos were transferred respectively. Results 1） In the group of patients aged 〈30 years, there was no significant difference in pregnancy outcomes with 1-3 embryos transferred. However, pregnancy rates were similar when 2 3 good-quality embryos were transferred, which was significantly higher compared with 0-1 good-quality embryos transferred; the incidence of multiple pregnancies was not an issue when only 1 embryo was transferred. 2） The pregnancy rate of the patients aged 30 34 was not significant not only when only 2-3 embryos were transferred but also when 2-3 good-quality embryos were transferred, which was significant compared with when 1 embryo or 0 1 good-quality embryo was transferred. The subgroup of 3 good-quality embryos transferred, at the same time, was expected to significantly increase multiple pregnancy rate. 3） For the patients aged 235, there were similar pregnancy rates in the subgroup involving 1-3 embryos transferred. Compared with 0-2 good-quality embryos transferred, the pregnancy rate was significantly higher in the patients with 3 good-quality embryos transferred. An increased trend toward multiple pregnancies was observed among not only the subgroups with 1-3 embryos transferred, but also when 1-3 good-quality embryos were transferred, although it was significantly higher in patients with 3 good-quality embryo transferred. Conclusion In an effort to achieve the ideal pregnancy rate without the risk of multiple pregnancies, it is desirable to employ a single good-quality embryo transfer for patients aged 〈30 years and 2 good-quality embryos for patients aged 330. As older women （aged 335 years）, this is important, need to abstain from poor-quality embryo transferred by increasing the number of embryos transferred in an effort to improve the rate of clinical pregnancy, if the patients have had enough 2 high-quality embryos.

Effects of Electroacupuncture on Expression of PI3K/Akt/Foxo3a in Granulosa Cells from Women with Shen (Kidney) Deficiency Syndrome Undergoing in vitro Fertilization-Embryo Transfer

Objective: To observe the effects of electroacupuncture(EA) on reproductive outcomes in women with Shen(Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer(IVF-ET),and explore the underlying molecular mechanism.Methods: Sixty-six infertile patients with Shen de?ciency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table,33 cases in each group.Before undergoing IVF,patients in the EA and control groups received EA therapy and placebo needle puncture,respectively,for 3 menstrual cycles.Shen de?ciency syndrome scores were assessed.Other outcome measures included the number of retrieved oocytes and fertilization,high-quality embryo and clinical pregnancy rates.Follicular ?uid was collected on the day of oocyte retrieval,and granulosa cell expression of phosphatidylinositide3-kinases(PI3 K),serine-threonine kinase(Akt) and forkhead box O3(Foxo3 a) m RNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction.Results: Syndrome scores for pre-versus post-treatments decreased significantly(16.53±1.75 to 8.67±1.61) in the EA group(P0.05),but showed no signi?cant change in the control group(17.18±1.58 to 14.74±1.58).A signi?cant difference in score change was found between the EA and control groups(P0.05).High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15%(195/282) vs.60.27%(176/292) and 66.67%(22/33) vs.42.42%(14/33),respectively,P0.05].The fertilization rate was equivalent in EA and control groups.No difference was found in the number of retrieved oocytes between the two groups.Granulosa cell expression levels of PI3 K and Akt m RNA were signi?cantly increased in the EA group compared with the control group,while the expression of Foxo3 a was reduced(all P0.05).Conclusions: For infertile patients with Shen de?ciency syndrome undergoing IVF,EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate.The EA-induced mechanism may involve regulation of PI3 K/Akt/Foxo3 a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis,possibly contributing to the improved clinical pregnancy rate(Registration No.Chi CTR 1800016217).

Predictive Value of Serum Vascular Endothelial Growth Factor and Pigment Epithelium-derived Factor in Ovarian Hyperstimulation Syndrome

Objective To explore whether the serum concentrations of vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) could serve as the predictors of ovarian hyperstimulation syndrome (OHSS) in patients undergoing in vitro fertilization-embryo transfer (IVF-ET). Methods Enzyme-linked immunoadsordent assay (ELISA) was employed to measure the serum concentrations of VEGF and PEDF on the day of hCG administration, oocyte retrieval and embryo transfer, respectively. Based on OHSS classification of the criteria of Golan, 85 patients were divided into three groups. Patients in group A (n=10) showed symptoms of severe OHSS and patients in group B (n=13) suffered from moderate OHSS. The control group (group C, n=62) contained patients without symptoms of OHSS as well as patients with mild OHSS. Results In groups A, B and C, serum concentrations of PEDF on the day of hCG administration (h-PEDF)(166.54 ± 102.81 pg/ml, 159.45 ± 136.77 pg/ml, 172.05 ± 170.95 pg/ml, P=0.48), oocyte retrieval (o-PEDF)(176.91 ± 103.37 pg/ml, 122.52 ± 92.54 pg/ml, 179.82 ± 177.47 pg/ml, P=0.27) and embryo transfer (e-PEDF)(169.02 ± 240.08 pg/ml, 136.80 ± 139.21 pg/ml, 157.38 ± 222.54 pg/ml, P=0.95), h-VEGF (175.55 ± 103.54 pg/ml, 218.84 ± 179.70 pg/ml, 153.39 ± 145.06 pg/ml, P=0.36) and o-VEGF (171.93 ± 128.55 pg/ml, 220.36 ± 149.82 pg/ml, 138.74 ± 139.30 pg/ml, P=0.15) showed no significant differences. There was a statistical difference in serum concentration of e-VEGF between group A (197.04 ± 156.63 pg/ml) and group C(110.69 ± 49.55 pg/ml)(P=0.008). The serum level of estradiol showed a positive correlation with the count of large follicles (r=0.744). The ratios of h-VEGF/h-PEDF, o-VEGF/o-PEDF and e-VEGF/e-PEDF were calculated and showed a clear difference among groups A, B and C (4.04 ± 3.39, 2.10 ± 2.14, 1.05 ± 4.80, P<0.001; 4.54 ± 5.69, 2.29 ± 1.67, 0.94 ± 0.59, P<0.001; 5.43 ± 6.16, 1.81 ± 1.36, 2.42 ± 2.60, P=0.04). Conclusion While neither serum concentrations of VEGF nor PEDF can be used as an OHSS predictor, the ratios of h-VEGF/h-PEDF, o-VEGF/o-PEDF and e-VEGF/e-PEDF may have great predictive value.
