An air-stable supported Cu(I) catalyst, Cu I@PS-Phen, was designed and synthesized. Cu I@PS-Phen can efficiently catalyze the click polymerization of diynes a and diazides b to produce soluble and thermally stable polytriazoles with high molecular weights(Mw up to 30800), and low copper residue content(down to 190 ppm) in high yields(up to 94.2%) under mild reaction conditions without the exclusion of oxygen.

目的评估以停氧为目标导向确定咖啡因疗程的方案对氧依赖早产儿的临床受益。方法选取2021年10月至2023年9月入住该院新生儿科219例早产儿,根据随机数字法分为干预组(以停氧为目标导向咖啡因治疗,n=108)和对照组(常规咖啡因治疗,n=111)。比较两组呼吸暂停复发、重复使用咖啡因、停用咖啡因时间、用氧时间及住院时间等指标差异。结果与对照组相比,干预组停用咖啡因纠正胎龄更大[(35.9±1.7)周vs.(34.4±1.5)周],住院时间更长[(64.62±20.60)d vs.(57.96±17.68)d],差异有统计学意义(P0.05)。结论以停氧为目标导向确定咖啡因疗程的方案不能减少早产儿的呼吸暂停复发风险及氧依赖,且有可能延长住院时间。
