Recent advances in the pathogenesis and treatment of hypoproteinemia after surgical stress / 中华危重病急救医学

After major operation,a series of complicated pathological and physiological changes will occur during the trauma and stress state.The protein synthesis is affected,which results in negative nitrogen balance.In addition,the release of inflammatory factors can damage the capillary endothelial cells and increase the permeability of micrangium,induce vascular colloidal albumin leakage to the extravascular tissue,decrease plasma albumin,make wound edema,eventually lead to postoperative hypoproteinemia.Except for albumin supplement,it should be aimed at the mechanism to control the stress response and reduce the leakage caused by the release of inflammatory factors to solve this problem radically in clinical work.The reports about the causes and treatment of hypoproteinemia after major surgery were reviewed to provide evidence for clinical treatment.

The regulatory effect of Ginsenside on NK cell activity via pituitary-adrenal axis in operative stress / 中国免疫学杂志

It was reported that immuno-regulatory mechanism of Ginsenoside on NK cell activity through pituitary-adrenal axis in operation stressed mice. Ginsenoside could modulate NK cell activity in mice against stress. On the other hand the level of plasma ACTH, corticosterone and the splenocyte ACTHR increased in stressed mice, as we know that ACTH, corticosterone could inhibite immunocyte function. However, Ginsenoside decreased the level of ACTH and corticosterone. This result suggests that the regulation effect of Ginsenoside on NK cell activity may be related to the action of pi tui taryadrenal axis under stress conditions.
