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.

准确有效地识别不良地质对隧道安全高效的施工至关重要。目前的不良地质识别方法主要依赖于地质学家的经验,容易出现误判和漏判。本研究提出了一种基于矿物异常分析的隧道不良地质识别方法(adverse geology identification through mineral anomaly analysis, AGIMAA),该方法基于地质异常理论,将矿物异常作为不良地质的识别标志。该方法首先基于探索性数据分析(exploration data analysis, EDA)计算矿物异常阈值,然后根据阈值评估矿物异常,最后根据矿物异常特征分析识别不良地质。建立了背景样本动态扩充流程,通过调整异常阈值实现对矿物异常的动态评估。该方法已在花岗岩隧道中得到验证和应用。在隧道里程142+800-142+860范围内,根据原岩矿物斜长石和角闪石含量的异常减少,以及蚀变矿物绿泥石、浊沸石和绿帘石含量的异常增加,成功识别出F37断层。当隧道进入不良地质影响区时,本研究所提出的方法可提供及时预警,并可识别隧道是在逐渐接近断层还是在远离断层。此外,本文还讨论了该方法的适用性、准确性及改进方向。该方法将传统隧道内不良地质识别分析从定性分析层面提高到了定量识别层面,可为采矿和地下工程中的不良地质识别提供参考和指导。

Preeclampsia (PE) is a pregnancy-specific, multi-system disorder and the leading cause of maternal and perinatal morbidity and mortality in obstetrics worldwide. Excessive vasoconstriction and dysregulated coagulation function are closely associated with PE. Heat shock protein 20 (HSP20) is ubiquitously expressed under normal physiological conditions and has important roles in vascular dilatation and suppression of platelet aggregation. However, the role of HSP20 in the pathogenesis of PE remains unclear. In this study, we collected chorionic plate resistance arteries (CPAs) and serum from 118 healthy pregnant women and 80 women with PE and detected the levels of HSP20 and its phosphorylated form. Both HSP20 and phosphorylated HSP20 were downregulated in CPAs from women with PE. Comparison of the vasodilative ability of CPAs from the two groups showed impaired relaxation responses to acetyl choline in preeclamptic vessels. In addition to the reduced HSP20 in serum from women with PE, the platelet distribution width and mean platelet volume were also decreased, and the activated partial thromboplastin time and thromboplastin time were elevated. With regard to the vital roles of HSP20 in mediating vasorelaxation and coagulation function, the decreased HSP20 might contribute to the pathogenesis of PE.
