优化精液处理中的密度梯度离心法以提高受精结局的探讨 [PDF]
目的本研究旨在改进生殖男科领域现有的精液处理方法，特别是针对双层密度梯度法中的300 ×g 20 min处理条件，以提高受精结局。方法收集2020年7月和9月以及2022年3月和5月在中山大学附属第六医院生殖医学中心进行辅助生殖助孕的1 623例患者的精液标本进行实验。预实验中，比较四种不同的双层密度梯度方法（200 ×g 10 min、200 ×g 20 min、300 ×g 10 min和300 ×g 20 min）处理后标本的精子DNA碎片率和回收率。然后，筛选出一种最优的方法作为新方法 ...

用全染色体涂抹探针进行卵母细胞第一极体荧光原位杂交 [PDF]
, 2006 【目的】建立用全染色体涂抹探针（WCP）对卵子第一极体进行荧光原位杂交（FISH）检测染色体的方法。【方法】收集单精子卵胞浆内注射（ICSI）中不成熟卵母细胞经体外培养成熟和常规试管婴儿（IVF）中未能成功受精的成熟卵母细胞，活检第一极体，固定后行13、14号染色体的全染色体涂抹探针荧光原位杂交。活检后，一部分卵母细胞固定行FISH以分析卵子自身的13、14号染色体，其余行ICSI受精，观察受精和卵裂情况。【结果】共获得成熟母细胞93个，成功活检85个，成功固定78个，共29个第一极体处于分裂中期 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−
