Synchrotron-based angle-resolved photoemission spectroscopy was employed to investigate the temperature evolution of the Yb 4 f spectral for surface and bulk in the Kondo lattice YbCu_(2)Si_(2).Our study quantitatively distinguishes between the surface and bulk hybridization processes,revealing that the onset temperatures for both surface and bulk hybridization processes are significantly higher than the Kondo ***,we found that the effective surface Kondo temperature is much lower than that of the *** findings offer valuable insights into the understanding of heavy fermion physics.

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.

Background: Patients with Parkinson's disease(PD) undergoing long-term levodopa therapy are prone to develop levodopa-induced dyskinesia(LID). Amantadine is the main drug recommended for the treatment of LID by current guidelines, but it is far from meeting clinical needs. Tianqi Pingchan Granule(TPG), a compound Chinese herbal medicine, has been developed to relieve symptom of ***: This randomized controlled trial evaluated the efficacy and safety of the combination of TPG and amantadine for ***, setting, participants and interventions: This is a randomized double-blind placebo-controlled trial,conducted from January 2020 to August 2021 at 6 sites in Jiangsu, Zhejiang and Shanghai, China. One hundred PD patients with ≥ 0.5 h of LID were randomly assigned to either the TPG plus amantadine group(TPG group) or the placebo plus amantadine group(placebo group), and treated for a period of12 weeks. To ensure unbiased results, all study participants, investigators and sponsors were unaware of group allocations. Additionally, the data analysts remained blinded until the analysis was *** outcome measures: The primary outcome was assessed using the Unified Dyskinesia Rating Scale(UDysRS)(Range 0–104). The key secondary end point was improvement of motor and non-motor symptoms. Safety analyses included all enrolled ***: One hundred patients were enrolled and randomized into the two treatment groups. The changes in UDysRS at week 12 were –11.02 for the TPG group and –4.19 for the placebo group(treatment difference –6.83 [–10.53 to –3.12]; P = 0.0004). Adverse events were reported for 2 of 50 patients(4.0%) in each of the ***: This study indicated that a 12-week treatment of amantadine plus TPG effectively reduced UDysRS scores and was well tolerated, demonstrating the efficacy and safety of TPG for the treatment of LID in PD.

目的探讨蛋白磷酸酶2A癌性抑制因子(CIP2A)的表达对脑胶质瘤患者的临床预后、胶质瘤细胞迁移和侵袭的影响及其作用机制.方法自中国脑胶质瘤基因组图谱(CGGA)提取脑胶质瘤CIP2A mRNA表达的相关数据和临床资料,分析CIP2A在胶质瘤中的表达情况;随后选取67例来源于2016年1月至2018年10月贵阳市第二人民医院神经外科的胶质瘤手术标本,采用免疫组织化学染色方法检测肿瘤组织的CIP2A表达水平.基于CGGA数据库资料,比较不同性别、年龄、世界卫生组织(WHO)分级、异柠檬酸脱氢酶(IDH)突变状态、染色体1p/19q共缺失状态、肿瘤类别(原发、复发、继发)、放化疗胶质瘤患者间CIP2A表达的差异.采用Kaplan-Meier生存分析、单因素Cox和多因素Cox回归模型及受试者工作特征(ROC)曲线探讨CIP2A的表达水平在胶质瘤患者预后评估中的价值.应用siRNA干扰U87和U251细胞中CIP2A的表达;采用实时荧光定量PCR(qRT-PCR)检测U87和U251细胞中CIP2A的表达水平;采用划痕实验和Transwell实验检测CIP2A基因沉默对U87和U251细胞迁移和侵袭能力的影响,以蛋白质免疫印迹实验检测U87和U251细胞中CIP2A蛋白、E钙黏蛋白(E-Cadherin)、基质金属蛋白酶(MMP)2和MMP9的表达水平.结果 CGGA数据库中,CIP2A mRNA的表达随着脑胶质瘤病理学级别的升高而增强(F=49.32,P<0.001);CIP2A低表达组患者的总生存期长于高表达组(CGGA数据库资料:P<0.001;临床样本资料:P<0.05).CIP2A高表达与肿瘤类别(复发和继发)、IDH野生型、1p/19q非共缺失显著相关,差异均有统计学意义(均P<0.001).ROC曲线分析显示,CIP2A mRNA表达水平预测脑胶质瘤患者1、3、5年生存率的曲线下面积分别为0.72、0.74和0.73.多因素Cox回归模型分析显示,CIP2A高表达、高龄、肿瘤复发或继发以及高级别肿瘤是脑胶质瘤患者预后的独立危险因素(均P<0.001).siRNA可抑制胶质瘤细胞U87和U251中CIP2A mRNA和蛋白的表达(均P<0.05),低表达CIP2A的U87和U251细胞的划痕愈合能力、细胞迁移和侵袭能力均明显下降(均P<0.05).低表达CIP2A的U87和U251细胞E-Cadherin的表达上调,而MMP2、MMP9蛋白的表达下调(均P<0.05).结论 CIP2A在脑胶质瘤中呈高表达并提示脑胶质瘤患者的预后不良,可能能够作为脑胶质瘤的相关预测标志物.CIP2A低表达可能通过调控上皮-间质转化抑制胶质瘤细胞的迁移和侵袭.
