1国外旅游扶贫研究进展显示文摘在相关概念辨析的基础上,对国外旅游扶贫理论、实践模式、效果、研究方法、相关国际组织的作用进行了综述。国外旅游扶贫形成了较为系统的理论体系与研究框架,为旅游实践提供了理论支持。从研究内容看,自然旅游、遗产旅游、农业旅游、社区旅游是旅游扶贫的主要方式;从扶贫效果看,旅游扶贫对当地经济有较大的促进作用,但需要合理的规划与操控才能可持续。旅游扶贫研究方法以宏观的定量研究为主,研究案例呈现地理集中性。今后应加强城市贫困问题、精准旅游扶贫及中国旅游扶贫案例的研究。李会琴 侯林春 杨树旺 J R Brent Ritchie 2015人文地理2015,30,1:147

4A comparison of the relative efficiency of ICSI and extended culture with epididymal sperm versus testicular sperm in patients with obstructive azoospermia显示文摘This is a retrospective cohort study comparing blastocyst transfer outcomes following intracytoplasmic sperm injection utilizing epididymal versus testicular sperm for men with obstructive azoospermia.All cases at a single center between 2012 and 2016 were included.Operative approach was selected at the surgeon’s discretion and included microepididymal sperm aspiration or testicular sperm extraction.Blastocyst culture was exclusively utilized prior to transfer.The primary outcome was live birth rate.Secondary outcomes included fertilization rate,blastulation rate,euploidy rate,and implantation rate.A mixed effects model was performed.Seventy-six microepididymal sperm aspiration cases and 93 testicular sperm extraction cases were analyzed.The live birth rate was equivalent(48.6%vs 50.5%,P=0.77).However,on mixed effects model,epididymal sperm resulted in a greater likelihood of fertilization(adjusted OR:1.37,95%CI:1.05–1.81,P=0.02)and produced a higher blastulation rate(adjusted OR:1.41,95%CI:1.1–1.85,P=0.01).As a result,the epididymal sperm group had more supernumerary blastocysts available(4.3 vs 3,P<0.05).The euploidy rate was no different.Pregnancy rates were no different through the first transfer cycle.However,intracytoplasmic sperm injection following microepididymal sperm aspiration resulted in a greater number of usable blastocysts per patient.Thus,the true benefit of epididymal sperm may only be demonstrated via a comparison of cumulative pregnancy rates after multiple transfers from one cohort.Scott J Morin Brent M Hanson Caroline R Juneau Shelby A Neal Jessica N Landis Richard T Scott Jr James M Hotaling 2020Asian Journal of Andrology2020,22,2:2
