脓毒症等危重疾病时物质与能量代谢具有高分解代谢的显著特点,早期的蛋白高分解代谢可向重要器官提供游离氨基酸,有利于机体保护性调节反应,如供给肝脏合成急性期蛋白及糖异生,供给免疫系统细胞和肠上皮细胞大量谷氨酸以适应其需要量的明显增加等。但是持续的蛋白高分解必将导? Sepsis and other critically ill diseases, the metabolism of matter and energy has the obvious characteristics of high catabolism. Early high protein catabolism can provide free amino acids to vital organs, which is conducive to the protective regulation of the body, such as the synthesis of acute phase synthesis of liver protein and sugar Heterotrophic, supply a large number of immune system cells and intestinal epithelial glutamate to meet the significant increase in their needs and so on. But sustained high protein decomposition will guide?
