概括
在儿科急性肝衰竭 (PALF) 中,严重的肝细胞损失和肝细胞前体细胞 (HPC) 活化增加与不良结果相关. 肝细胞增殖减少和衰老增加也表明这些儿童的预后更差.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 儿科胃肠病学 儿科胃肠病学
- 再生医学是一种再生医学.
背景情况:
- 儿科急性肝衰竭 (PALF) 在理解肝原生细胞 (HPC) 活动和肝脏再生方面提出了复杂的挑战.
- 肝脏组织学,HPC活性和PALF患者结果之间的临床病理相关性需要进一步阐明.
研究的目的:
- 调查肝脏组织学,HPC活性和PALF儿童的临床结果之间的关系.
- 为了确定儿科急性肝衰竭结果的组织学预测因素.
主要方法:
- 来自PALF患者的肝脏组织学样本的分析.
- 对肝细胞损失,HPC活性 (CK7,CK19,SOX9,EpCAM),肝细胞增殖 (Ki67) 和衰老 (p53,p21) 的评估.
主要成果:
- 其中包括94名儿童;23.4%的儿童存活下来是本地肝脏 (SNL),而35.1%的儿童死亡,41.5%的儿童接受了肝脏移植 (LT).
- 与较差结局组相比,SNL组的肝细胞损失较少,HPC较少,肝细胞增殖较多,肝细胞衰老较少 (p < .05).
- 肝细胞损失严重程度 (调整后OR:9.95) 是不良结果的独立预测指标;80%的肝细胞损失>50%的儿童在10天内有不良结果.
结论:
- 在PALF中,严重的肝细胞损失,增加的HPC激活,减少的肝细胞增殖和升高的肝细胞衰老与糟糕的结果有关.
- 肝细胞50%以上的损失是儿科急性肝衰竭中不良结果的重要独立预测因素.

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
