Gut microbial balance and liver transplantation: alteration, management, and prediction

Liver transplantation is a conventional treatment for terminal stage liver diseases. However, several complications still hinder the survival rate. Intestinal barrier destruction is widely observed among patients receiving liver transplant and suffering from ischemia–reperfusion or rejection injuries because of the relationship between the intestine and the liver, both in anatomy and function. Importantly, the resulting alteration of gut microbiota aggravates graft dysfunctions during the process. This article reviews the research progress for gut microbial alterations and liver transplantation. Especially, this work also evaluates research on the management of gut microbial alteration and the prediction of possible injuries utilizing microbial alteration during liver transplantation. In addition, we propose possible directions for research on gut microbial alteration during liver transplantation and offer a hypothesis on the utilization of microbial alteration in liver transplantation. The aim is not only to predict perioperative injuries but also to function as a method of treatment or even inhibit the rejection of liver transplantation.

以直杆轴向拉伸为例说明:单元体斜截面上的平衡应力只是保证斜截单元体平衡的应力,不是保证其上质点平衡的应力;单元体平衡与质点平衡是不同的。推导出二向应力状态下质点的平衡应力为σ′α=(σ2x+σ2y+2τ2+2τ(σ2x+σ2y)1/2(sinα2+cosα2))1/2,质点平衡应力σ′α与x轴的夹角为αx=arctan(τ+(σ2x+σ2y)1/2sin arctan (σy/σx))/(τ+(σ2x+σ2y)1/2cos arctan(σy/σx))。推导出二向应力状态质点平衡应力的极值条件:σx=σy;应力σ'α在与X轴成45°的对角线上;极大值为σ'α max=21/2(σx+τ)。推导出质点平衡应力比最大主应力σ1=σx+τ大21/2倍。指出σ'α max与σ1分别发生在两个互相垂直的对角线平面上,且与x轴夹角分别为±45°。 用质点平衡应力建立了新的拉(弯)一剪(扭)组合变形条件σ'α=(σ2 + 2τ2+2στ)1/2≤ [σ],它不同于现行 的第三强度理论公式(σ2 + 4τ2)1/2≤ [σ]和第四强度理论公式(σ2 + 3τ2)1/2< [σ];同时,建立了三向应力状 态下第四强度理论的新公式σ'd= (σ21+σ22+σ23)1/2≤ [σ],进而推导出正方体被三向等应力拉伸时其最小破坏 应力值为0.58σs。它不同于现行的第四强度理论公式σxd[ (σ1-σ2)2+ (σ2-σ3)2+ (σ3-σ1)2) /2]1/2≤ [σ],推翻了正方体被三向等应力拉伸时,无论多大应力都不会被破坏的错误结论。
