摘要：采用电子束熔化(EBM)成形工艺,制造具有可控多孔结构的Ti6Al4V植入体,分析测试其微观孔隙结构特征、孔隙率以及力学性能。扫描电镜观测结果表明,所制备的钛合金植入体孔隙结构特征与设计结构相符合,证明EBM技术能够实现钛合金植入体孔隙结构的控制;测得多孔植入体的孔隙率为60.1%,相应的抗压强度为163MPa,弹性模量为14GPa,与人体骨组织弹性模量相近。利用改进的碱热处理方法进行表面改性,并浸泡在模拟体液中以诱导磷灰石的形成。体外细胞培养试验结果表明,培养7d后成骨细胞在改性的试件表面大量粘附、生长、增殖。

摘要：Purpose: Can Cortisol Releasing Hormone (CRH) levels in follicular fluid predict outcomes following assisted reproductive treatment (ART) cycles? Methods: Prospective cohort study of 50 women undergoing in vitro fertilisation (IVF)/intra-cytoplasmic sperm injection (ICSI) cycles over a two month study period. All patients were treated on the long stimulation protocol;follicular fluid was aspirated and pooled for each patient. The samples were processed appropriately and assayed using CRH radioimmunoassay (RIA). Results: This study confirmed that CRH was present in follicular fluid. The average level detected was 173 ± 9 pg/mL (mean ± standard error of mean [SEM]). The data suggests a positive correlation of CRH follicular fluid levels greater than 145 pg/mL with successful ART outcomes. Conclusion: The data indicates a positive correlation between ART outcomes and the presence of follicular fluid CRH levels greater than 145 pg/mL. The results should be interpreted with caution due to the small sample size and pooling of follicular fluid per patient. Furthermore, the pooling of follicular fluid is not representative of CRH levels in an individual follicle, and thus, mature oocyte. This study serves as a reminder to what has previously been hypothesised.
