Amyotrophic lateral sclerosis(ALS)is a fatal neurodegenerative disease characterized by progressive degeneration of motor neurons,and it demonstrates high clinical heterogeneity and complex genetic architecture.A variation within TRMT2B(c.1.56G>T;p.K452N)was identified to be associated with ALS in a family comprising two patients with juvenile ALS(JALS).Two missense variations and one splicing variation were identified in 1. patients with ALS in a cohort with 91. patients with ALS,and three more variants were identified in a public ALS database including 331. patients with ALS.A decreased number of mitochondria,swollen mitochondria,lower expression of ND1.decreased mitochondrial complex I activities,lower mitochondrial aerobic respiration,and a high level of ROS were observed functionally in patient-originated lymphoblastoid cell lines and TRMT2B interfering HEK293 ***,TRMT2B variations overexpression cells also displayed decreased *** conclusion,a novel JALS-associated gene called TRMT2B was identified,thus broadening the clinical and genetic spectrum of ALS.

随着社会现代化进程的迈进,愈加频繁的人类活动加剧了土壤重金属污染。当土壤中重金属元素含量超过风险筛选值时,会经过食物链摄入人体,过量的重金属累积对人体健康造成损害。筛选出具有重金属污染风险的土壤是治理土壤污染的重要环节。采用X射线荧光(XRF)光谱仪获取了59份国家标准土壤样品的光谱数据,然后对其进行小波阈值去噪和迭代离散小波变换本底扣除等预处理;运用基于竞争性自适应重加权采样(CARS)算法对土壤中的重金属元素进行谱线筛选;将筛选后的结果作为模型的输入,通过建立1.-CNN模型预测土壤样本是否具有重金属污染的风险。实验结果显示,通过CARS算法采样后的特征通道数大幅度减少,Ni、Cu、As、Pb元素从原来的2048个特征点分别减少为37、53、37、45个,为原来通道数的1.81.~2.59%。相较于不筛选和连续投影(SPA)筛选方法,结合CARS算法的1.-CNN模型在判断土壤样品是否有Ni、Cu、As、Pb元素污染风险时的准确率分别可以达到96.67%,93.22%,91.67%,88.33%。经CARS筛选,1.-CNN比偏最小二乘回归(PLSR)方法在预测准确性方面有明显优势。提出的CARS-1.-CNN算法在提高模型预测准确率的同时减少了模型的计算量,对于XRF光谱土壤重金属元素污染风险筛选具有较好的理论指导和应用价值。

Intestinal macrophages play crucial roles in both intestinal inflammation and immune homeostasis. They can adopt two distinct phenotypes, primarily determined by environmental cues. These phenotypes encompass the classically activated pro-inflammatory M1.phenotype, as well as the alternatively activated anti-inflammatory M2 phenotype. In regular conditions, intestinal macrophages serve to shield the gut from inflammatory harm. However, when a combination of genetic and environmental elements influences the polarization of these macrophages, it can result in an M1.M2 macrophage activation imbalance, subsequently leading to a loss of control over intestinal inflammation. This shift transforms normal inflammatory responses into pathological damage within the intestines. In patients with ulcerative colitis-associated colorectal cancer (UC-CRC), disorders related to intestinal inflammation are closely correlated with an imbalance in the polarization of intestinal M1.M2 macrophages. Therefore, reinstating the equilibrium in M1.M2 macrophage polarization could potentially serve as an effective approach to the prevention and treatment of UC-CRC. This paper aims to scrutinize the clinical evidence regarding Chinese medicine (CM) in the treatment of UC-CRC, the pivotal role of macrophage polarization in UC-CRC pathogenesis, and the potential mechanisms through which CM regulates macrophage polarization to address UC-CRC. Our objective is to offer fresh perspectives for clinical application, fundamental research, and pharmaceutical advancement in UC-CRC.
