简介：在一个季节传递火车引起的路基的颤动特征和变细结盟Daqing的冻结的区域，中国被调查。三个地实验整个一年在不同时间期间被进行，在正常，分别地，冻结并且融化时期并且季节，火车速度和火车类型的影响，在这篇论文被描述。结果显示出那：(1)垂直部件在栏杆课程附近的测量颤动的三个部件之中是最大的，并且当到铁路课程的距离增加，主导的颤动取决于季节。(2)与在正常时期的颤动相比，当侧面的颤动在结冰时期减少时，垂直、纵的颤动增加。在融化的时期，然而，垂直、纵的颤动减少，和侧面的颤动增加。(3)当火车加速增加，路基颤动增加。(4)一列货船火车导致的颤动比由一辆客车大。这些观察提供颤动和路基的动态稳定性的更好的理解并且可能在在冷区域为铁路和大楼建设开发标准有用。

简介：AbstractObjective:To explore the best timing for frozen embryo transfer (FET) after ovarian stimulation and egg retrieval using the clomiphene citrate (CC) + human menopausal gonadotropin (hMG) ovulation induction regimen through a retrospective analysis.Methods:Data of patients who underwent CC + hMG ovulation induction and FET from January 2014 to December 2019 were analyzed retrospectively. The patients were divided into three groups according to the interval from egg retrieval to FET: CC1 (within 1 menstrual cycle), CC2 (2 menstrual cycles), and CC3 (≥ 3 menstrual cycles). Indicators such as hormone levels and pregnancy outcomes were recorded to explore the effect of different intervals on pregnancy outcome.Results:A total of 1,082 transfer cycles were included in this retrospective analysis. The implantation, clinical pregnancy, and live birth rates in the CC1 group were significantly lower than those in the CC2 and CC3 groups (P < 0.05). The E2/P4 ratio on progesterone injection day (3 days before thawed embryo transfer) was lower in the CC1 group than in the other groups (P < 0.05). After adjusting for all factors using multifactor regression analysis, the interval between egg retrieval and FET was found to be an independent predictor of the implantation, pregnancy, and live birth rates.Conclusion:An interval of more than one menstrual cycle between the day of egg retrieval after ovarian stimulation with the CC + hMG ovulation induction regimen and the day of FET can result in high implantation, clinical pregnancy, and live birth rates, which can lead to an improved pregnancy outcome.

简介：AbstractObjective:There are few reports of live births from heterotopic transplantation of frozen-thawed ovarian tissue. The purpose of this study is to assess the follicular development in the frozen-thawed ovarian tissues following heterotopic transplantation in both female and male bodies.Methods:Cluster of differentiation 1 (CD1) mice (6-8 weeks) were used in this study as ovarian tissue donors and foster mothers for embryo transfer. Sperm from CD1 male mice were used for insemination by intracytoplasmic sperm injection (ICSI). Nude severe combined immunodeficiency mice (8 weeks) were employed as recipients of ovarian tissue transplantation. The frozen-thawed ovarian tissues were transplanted to 4 sites on each mouse, female and male, subcutaneously. After 3 months, both female and male mice were injected with 5.0 IU gonadotropins intraperitoneally. Post 48 hours of injection, the mouse was killed for ovarian transplant collection. Only fully grown oocytes with contacted cumulus cells (cumulus-oocyte complexes) were then selected for maturation in vitro. In vitro matured oocytes were inseminated with fresh sperm by ICSI, and the developed blastocysts were frozen using the vitrification method and stored until embryo transfer. After thawing, the thawed blastocysts were incubated for at least 2 hours before the transfer. The foster mice mothers mated with vasectomised male 3 days previously. Live birth was monitored at 19 days after transfer, and the resulted offspring was raised for fertility test.Results:The relatively high recovery rates of the transplanted ovarian tissues were collected in both frozen-thawed and fresh ovarian tissue transplants from both female and male bodies. The fully grown immature oocytes became mature in vitro and the fertilized zygotes developed to blastocyst stage. There are no differences between frozen-thawed and fresh ovarian transplants in term of oocyte quality and embryo development to blastocyst rates. Nineteen-day post-transfer, 3 foster mothers from the frozen-thawed ovarian tissue transplant group delivered 13 pups and the 4 foster mothers of the fresh ovarian tissue transplant group delivered 12 live pups. The produced offspring were normal in appearance and grew healthy and fertile.Conclusions:Our results attest that the follicles can survive and develop in the frozen-thawed ovarian tissues following the subcutaneous transplant to adult male mouse’s body regardless of basal endocrinal environment. Those fully grown oocytes can produce healthy and fertile offspring which will provide the possibility for further mechanistic understanding of endocrinology of folliculogenesis.
