    Sources analysis and risk assessment of heavy metals in soil in a polymetallic mining area in southeastern Hubei based on Monte Carlo simulation by Jing Wang, Bo Wang, Qibin Zhao, Jinnan Cao, Xiao Xiao, Di Zhao, Zhenya Chen, Di Wu

    Published 2025-01-01
    “…The main findings are as follows: (1) Among the heavy metals present in the soil, copper (Cu) has the highest average concentration at 278.54 mg/kg, followed by zinc (Zn) at 161.16 mg/kg, chromium (Cr) at 75.23 mg/kg, nickel (Ni) at 30.38 mg/kg, arsenic (As) at 22.53 mg/kg, cadmium (Cd) at 0.76 mg/kg, and mercury (Hg) at 0.14 mg/kg; (2) The distribution of heavy metal concentrations exhibits significant regional variations, with the spatial pattern of pollution indicating that TLS is more affected than JLS, as evidenced by the Pollution Load Index (PLI) values; (3) Three potential sources of heavy metals were identified: natural sources, anthropogenic activities (including industrial production and agricultural practices), and atmospheric deposition (both dry and wet); (4) While severe contamination levels of specific metals such as copper and cadmium are observed in JLS and TLS soils, the overall contamination is mild, suggesting complex contamination dynamics; (5) Cadmium poses a moderate to high ecological risk, being the most sensitive factor in the comprehensive ecological risk assessment with a contribution rate of 65.2 %; (6) The concentrations of heavy metals in the soil present certain health risks, with children being more vulnerable than adults. …”

    IL-33 Deficiency Attenuates Lung Inflammation by Inducing Th17 Response and Impacting the Th17/Treg Balance in LPS-Induced ARDS Mice via Dendritic Cells by Li Cheng, Yang Jiao, Wei Jiang, Xin Zhang, Liping Zhang, Gongwei Jia

    Published 2022-01-01
    “…Dendritic cells (DCs) can regulate the differentiation of CD4+ T cells, including Th17 and Treg cells. Recent evidence revealed that interleukin-33 (IL-33) signaling could activate and mature DCs. …”

    DNA损伤修复基因<italic>FANCI</italic>与肝癌预后和免疫浸润相关性 by 游莹, 梅美华, 谭宁歆, 陈怡丽, 池沛冬, 何晓顺, 黄俊琪

    Published 2023-01-01
    “…结果与正常组织相比,肝癌组织FANCI的mRNA和蛋白表达水平上调(<italic>P</italic>&lt;0.001);高表达FANCI的肝癌患者预后较差(<italic>P</italic>&lt;0.001);肝癌组织中FANCI的表达与组织活化的CD4<sup>+</sup>T细胞数目、Th2细胞数目及免疫检查点基因的表达呈正相关,且FANCI高表达组的B细胞及巨噬细胞浸润水平明显较低(<italic>P</italic>&lt;0.01);GO及KEGG富集分析显示FANCI相关基因富集在氨基酸跨膜转运体活性等多种生物过程中;细胞实验发现敲低FANCI后,肝癌的增殖、侵袭及迁移能力下降(<italic>P</italic>&lt;0.05)。…”
