Totally 294 infertile patients with EMs were enrolled. And 109 patients （116 cycles） received prolongedprotocol as the control, 185 patients （193 cycles） received long protocol as case group, all followed by standard controlled ovarian hyperstimulation （COH）. Response to gonadotropins, the fertilization rate, the cleavage rate, the implantation rate, the clinical pregnancy rate and the miscarriage rate were measured and analyzed between the two groups. Results A trend toward better ovarian response was observed in long protocol group. Higher fertilization rate, lower total dose of rFSH, shorter duration of stimulation and more endometrial thickness on the day of hCG injection were observed in long protocol group compared with those of prolonged protocol group, and the difference was significant （P〈0.05）. In addition, the clinical pregnancy rate, the cleavage rate and the implantation rate also had an increase trend in long protocol group compared with those of prolonged protocol group, but without significant differences. Conclusion Long protocol regimen before IVF-ET in patients with EMs resulted in a trend toward better ovarian response and higher clinical pregnancy rates than prolonged protocol regimen did.展开更多
传统TCP(transmission control protocol)本是为有线网络设计,它假设包丢失全是由网络拥塞引起,这个假设不能适应于MANET (mobile ad hoc network),因为MANET 中除了拥塞丢包以外,还存在由于较高比特误码率、路由故障等因素引起的丢包现...传统TCP(transmission control protocol)本是为有线网络设计,它假设包丢失全是由网络拥塞引起,这个假设不能适应于MANET (mobile ad hoc network),因为MANET 中除了拥塞丢包以外,还存在由于较高比特误码率、路由故障等因素引起的丢包现象.当出现非拥塞因素丢包时,传统 TCP 将错误地触发拥塞控制,从而引起TCP 性能低下.任何改进机制都可以分为发现问题和解决问题两个阶段.首先概括了 MANET 中影响 TCP 性能的若干问题;然后针对发现问题和解决问题两个阶段,详细地对每一阶段中存在的各种可行方法进行了分类、分析和比较;最后指出了 MANET 中 TCP 性能优化的研究方向.展开更多
