The etiology of preeclampsia (PE) remains poorly understood. Recent years have seen deepening research into epigenetics, where acetylation modifications of histones have garnered significant attention for their roles in various diseases, particularly in tumor pathologies. Several studies have indicated a crucial role for histone 3 acetylation in PE and hypoxia. Additionally, abnormal expressions of histone deacetylases (HDACs) and/or histone acetyltransferases (HATs) are implicated in the pathogenesis and progression of PE. This review aims to analyze the changes in histone 3 in PE, as well as the mechanisms underlying HDACs and HATs and their upstream or downstream target genes in the disease to elucidate the role of histone acetylation modifications in PE. It also seeks to uncover the potential clinical value of histone acetylation modulatory inhibitors, particularly HDAC inhibitors, in PE.

Nealy 80% cerebral palsy infant are accompanied with speech obstacle at different degree, which always lead to intelligent and communication difficulties, much attention should be paid on special training. This arcle will introduce the four main aspects types of speech obstacle, the reason of speech obstable, the examination and evaluation of speech obstacle, and treatment of speech obstacle.
