At a glance

Pinyin: niào xuè
Simplified: 溺血
Literal: 溺血 niào xuè — urine, and blood. 溺 is read niào here, the old graph for what is now written 尿; the same graph read nì means to drown, and the chapter is not drowning anyone. 血 is read xuè throughout this site. The line pairs the two signs the bladder produces when heat reaches it from the 胞: 癃, the dribbling block, and blood in the urine. It is the first of the chapter's transmissions to cross out of the five stores and into the bowels and bladder.
Shuowen: 《說文解字》：溺，水名——**本義為水名，假借為「尿」（「尿」讀 niào），讀 niào**；**又讀 nì，為沈溺之溺**。「溺」讀 niào，本篇惟此一見，**通「尿」，讀 niào，不作溺水之 nì 讀**；「血」讀 xuè，**本站「血」一律讀 xuè**；「癃」讀 lóng，本篇惟此一見；「胞」讀 bāo。

In brief

Blood in the urine, together with a dribbling block: what the bladder produces when the 胞 shifts heat into it. 溺 is read niào, not nì.
