概括
大型手术可能会导致大脑损伤,但神经保护性麻醉可以预防它. 手术后的状纤维酸蛋白 (GFAP) 水平下降,而神经元特异性酶 (NSE) 增加,但NSE可能不会在肝移植期间表明大脑损伤.
科学领域:
- 神经科学是一个神经科学.
- 生物化学 生物化学
- 麻醉学 麻醉学
背景情况:
- 大型手术后的神经炎症可能会导致神经元损伤.
- 生物化学标记物如S100β (S100β),神经元特异性酶 (NSE) 和状纤维酸蛋白 (GFAP) 可以检测出这种大脑损伤.
- 评估这些标志物对于理解手术过程中的神经毒性至关重要.
研究的目的:
- 在接受肝移植的患者中评估神经元损伤的程度.
- 为了将脑损伤的生物化学标记与肝移植后的认知功能变化相关联.
主要方法:
- 33名肝移植患者的认知功能使用手术前和后的迷你精神状态检查 (MMSE) 进行了评估.
- 同时,测量了S100β,NSE和GFAP的血清水平.
- 进行了统计分析,以比较手术前和手术后的值.
主要成果:
- 在手术前和手术后评估之间,MMSE得分没有显著差异.
- 经手术后GFAP水平的统计学显著下降 (P < 0.05).
- 观察到手术后NSE水平的统计学上显著增加 (P <0.05),而S100 β显示微不足道的下降.
结论:
- 神经保护性麻醉方案可以在肝移植期间保护患者免受大脑损伤和术后认知功能障碍.
- 肝移植期间NSE水平的显著增加可能归因于直接神经元损伤以外的其他因素.
- 在肝移植的背景下,NSE应谨慎地解释为脑损伤的标志物.

Tissue Transplantation
396
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Liver Regeneration

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.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...
