Objective:Although consensus on the optimal endometrial preparation protocol for frozen-thawed embryo transfer(FET)is lacking,this is particularly true for patients with infertility and a history of endometrial polyps(EPs).In this study,we aimed to investigate whether a gonadotropin-releasing hormone agonist combined with hormone replacement therapy(GnRHa-HRT)could improve pregnancy outcomes in single euploid FET for patients with a history of ***:In this retrospective cohort study,395 women who underwent their first single euploid FET cycle were divided into groups according to endometrial preparation protocols as follows:natural cycle(NC)(n=220),hormone replacement therapy(HRT)(n=122),and GnRHa-HRT groups(n=53).Subsequently,the FET cycles in the three groups were subdivided according to maternal *** patients underwent hysteroscopic polypectomy before FET,and their EPs were confirmed by ***:No statistically significant differences were observed in live birth rates among the three groups(58.64%vs.58.20%vs.56.60%,P=0.964).Furthermore,the rates of miscarriage,ectopic pregnancy,premature live birth,and pregnancy complications were comparable among the three groups(P>0.05).After adjusting for potential confounding factors,no significant differences in pregnancy outcomes were reported between the groups(adjusted odds ratios[OR]and 95%credible intervals[CI]for live birth rate,***:1.119,0.660–1.896,P=0.677;***:1.165,0.610–2.226,P=0.643).Additionally,the pregnancy outcomes of the FET cycle were not influenced by the endometrial preparation protocols in the subgroups when stratified by maternal age(P>0.05).Conclusion:GnRHa-HRT did not improve the pregnancy outcomes of the single euploid FET in patients with a history of EPs.

Effective diffusion of a tracer in active bath: A path-integral approach

引用

National Science Open 2024年第4期3卷 29-40页

作者： Mengkai Feng Zhonghuai Hou Hefei National Research center for Physical Sciences at the Microscale & Key laboratory of Precision and Intelligent Chemistry University of Science and Technology of China

We investigate the effective diffusion of a tracer immersed in an active particle bath consisting of self-propelled particles. Utilising the Dean's method developed for the equilibrium bath and extending it to the nonequilibrium situation, we derive a generalized Langevin equation(GLE) for the tracer particle. The complex interactions between the tracer and bath particles are shown as a memory kernel term and two colored noise terms. To obtain the effective diffusivity of the tracer, we use path integral technique to calculate all necessary correlation functions. Calculations show the effective diffusion decreases with the persistent time of active force, and has rich behavior with the number density of bath particles, depending on different activities. All theoretical results regarding the dependence of such diffusivity on bath parameters have been confirmed by direct computer simulation.
