缺氧缺血后胃肠道粘膜上皮凋亡的证据自细胞凋亡概念提出后,缺氧缺血后胃肠粘膜是否存在凋亡?引起了学者们的关注。传统观念认为,缺氧缺血性胃肠粘膜表现为细胞坏死,而与细胞凋亡无关(1)。目前认为,凋亡与坏死有着本质区别(2),其发病的内在调控机制是不同的,细胞死亡是细胞肿胀 Evidence of Apoptosis in Gastrointestinal Mucosal Epithelium After Hypoxia-Ischemia Since the concept of apoptosis has been proposed, whether there is apoptosis in the gastrointestinal mucosa after hypoxic-ischemic attacks has drawn the attention of scholars.

At present, there is an essential difference between apoptosis and necrosis (2), the pathogenesis of which is different from the internal control mechanism, cell death is cell swelling
