Ovarian hyperstimulation and ICSI procedureswere performed by conventional protocol. The sperm was collected by percutaneous epi-didymal sperm aspiration (PESA) or testicular sperm extraction (TESE).Results:The fertilization rate (73.1% vs. 67.0%), cleavage rate (88.6% vs. 86.3%), embryo implantation rate (20.7% vs. 11.4%), clinical pregnancy rate per trans-fer cycle (35.7% vs. 19.6%) were obtained for obstructive and non-obstructiveazoospermia, respectively.Conclusion: The results revealed that in the cases of obstructive azoospermia, ferti-lization rate, embryo implantation rate and clinical pregnancy rate were significantlyhigher than those of non-obstructive azoospermia. But there was no significant differ-ence of the cleavage rate between two groups.展开更多
高迁移率族蛋白B1(high-mobility group box 1,HMGB1)是一种保守的核蛋白,对维持核小体稳定、DNA重组、复制、修复及转录有重要作用。其可由坏死的细胞被动释放,或在适宜刺激下主动分泌至胞外。近年的研究显示:HMGB1信号的活化与肺损伤...高迁移率族蛋白B1(high-mobility group box 1,HMGB1)是一种保守的核蛋白,对维持核小体稳定、DNA重组、复制、修复及转录有重要作用。其可由坏死的细胞被动释放,或在适宜刺激下主动分泌至胞外。近年的研究显示:HMGB1信号的活化与肺损伤、肺纤维化、肺癌等肺部疾病的发展密切相关,而阻断HMGB1信号可抑制其病理进程,说明HMGB1的抑制对这类疾病有潜在治疗价值。该文就HMGB1在呼吸系统疾病中的作用及其机制作一综述,以期为上述疾病的诊断和治疗提供新的理论依据。展开更多
