摘要
目的:
早期妊娠出血(First-trimester bleeding)是指妊娠三个月内发生的阴道出血。常见原因有流产,异位妊娠等。其中先兆流产是最常见的原因之一,而体外受精-胚胎移植(invitro fertilization-embryo transfer,IVF-ET)早期妊娠出血率明显高于正常妊娠。其原因尚未明了。本研究对通过实施IVF-ET技术妊娠早期出血及未出血妇女的基础血清卵泡刺激素(FSH)、黄体生成素(LH)、雌二醇(E2)水平以及妊娠30天、45天雌二醇(E2),孕酮(P)水平, B超检查胚胎着床位置,以及子宫位置探讨其出血的原因,以便及早的采取人为的干预,改善IVF-ET的妊娠结局
方法:
1研究对象:

Purpose:
Early pregnancy bleeding (First-trimester bleeding) are referring to happen within three months of pregnancy vaginal bleeding. In vitro fertilization - embryo culture (invitro fertilization-embryo transfer, IVF-ET) high abortion rate, early pregnancy bleeding pregnancy rate is much higher than normal. Unknown reasons.Through this experiment, human assisted reproductive technology (Assisted Reproductive Technology ART), as well as after a natural pregnancy bleeding during early pregnancy in patients with basic serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) level and 30 of pregnancy days of estradiol (E2), progesterone (P) level of 45 days of pregnancy estradiol (E2), progesterone (P) levels and implantation location of B-ultrasound, uterine hemorrhage location to explore the reasons for so early take man-made interventions to improve the IVF-ET Pregnancy Outcome。
Methods:
1 study: From November 2008 to January 2009 at my Branch in vitro fertilization - embryo transfer (invitro fertilization-embryo transfer, IVF-ET) with intracytoplasmic sperm injection - embryo transfer (intracytoplasmic sperm injection-embryo transfer ICSI-ET) of 39 cases of pregnancy, age at 24-35 years old, the average age of 29.56±3.14, are the first pregnancy, tubal factor infertility as well as the former are male factors, exclusion of habitual abortion, maternal reproductive tract abnormalities and anatomical structures within the uterus membrane lesions, early pregnancy without a cold, fever history, no medication history, then no radiation or the history of harmful chemical substances; no smoking, drinking and other bad habits, with non-consanguineous marriage.
1.1 Experimental group (early pregnancy bleeding group): 12 weeks of pregnancy there appeared nine cases of patients with vaginal bleeding, age 30.11±3.10 years old
1.2 Control group: the same period in IVF / ICSI pregnancy 30 cases of other patients, 12 weeks of pregnancy does not appear vaginal bleeding, age 29.40±3.18 years old,
All patients are first child, pregnancy, rule out the possibility of habitual abortion, maternal reproductive tract anatomy and abnormal endometrial lesions, early pregnancy without a cold, fever history, no medication history, then no radiation or the history of harmful chemical substances; no smoking , alcohol and other bad habits, with non-consanguineous marriage.
2 Research Methods and Determination of Content:
2.1 Determination of embryo implantation Location: B super-center distance measured progesterone capsule away from the mouth of the cervix
2.2 Determination of endocrine hormone: basic Chemiluminescence Determination of serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and 30 days of pregnancy 45 days of estradiol (E2), progesterone (P).
Results:
1 experimental group and control group basic FSH, LH, E2 Comparison
①basic FSH, respectively (6.65±1.05 mIU / ml vs 7.23±1.60mIU/ml),②basic LH, respectively (5.19±0.88mIU/ml vs 4.71±1.05mIU/ml),③basic E2, respect ively (39.00±6.04pg/ml vs 39.57±13.02 pg / ml)
2 the experimental group and control group 30 days of pregnancy compared E2.P level
①experimental group E2 1435.22±733.08 pg / ml VS 2425.77±1055.08pg/ml
②experimental group P 36.35±5.85 pg / ml VS 38.14±4.80pg/ml
3 the experimental group and control group 45 days of pregnancy compared E2.P level
①experimental group E2 1886.89±1087.59 pg / ml VS 2773.37±844.17pg/ml
②experimental group P 36.89±5.35 pg / ml VS 38.90±3.23pg/ml
4 with the control group 45 days of pregnancy embryo implantation B-Determination of the location of the experimental group compared 34.00±8.26mm VS 43.00±7.21mm
Experimental group, three cases of anterior implantation, the posterior wall of six cases of implantation, the anterior wall of the control group 13 cases of implantation, the posterior wall of 17 cases of implantation
Experimental group, 7 cases of uterine anterior, posterior uterine Example 2, the control group 25 cases of anterior uterus, 5 cases of posterior uterine
Conclusion:
1 patients compared with the control group, experimental group of patients with basic serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) level was no significant difference
2 pregnant 30 days, experimental group of patients with estradiol (E2) level was lower than the control group (P <0.05), progesterone (P) level of no significant difference 3 of pregnancy 45 days, experimental group of patients with estradiol (E2) level was lower than the control group (P <0.05), progesterone (P) level of no significant difference
4 lines 45 days of pregnancy vaginal ultrasonography B, the experimental group is lower than on the embryo implantation
Control group (P <0.05), the experimental group and control group, no significant difference between the location of the uterus. Implantation in the uterine wall position was no significant difference
So the diagnosis of bleeding of early pregnancy early only estradiol (E2), embryo implantation Location prediction has significance
