    急性心肌梗死(MI)被认为是充血性心力衰竭的主要原因。这项研究的目的是提供对病理生理过程的深入分析,并为急性MI的发生提供干预的关键目标。
    结扎左前降支建立大鼠MI模型。心脏组织,收集心外膜脂肪组织(EAT)和皮下脂肪组织(SAT)。用H9c2细胞探讨补体因子D(CFD)调控心肌细胞凋亡的机制。
    在MI大鼠中观察到心肌细胞凋亡,在体内MI组中发现了更多的EAT。通过EAT制备的条件培养基(EAT-CM)显著降低H9c2细胞的活性。EAT中CFD的含量显著增加,CFD在体外促进心肌细胞凋亡,CFD-IN1(CFD的选择性抑制剂)可以改善这种作用。CFD诱导聚ADP-核糖聚合酶-1(PARP-1)过度激活。此外,在SAT-CM+CFD组中添加pan-caspase抑制剂Z-VAD不影响H9c2细胞凋亡。CFD通过PARP-1激活诱导细胞凋亡,PARP-1抑制剂3-氨基苯甲酰胺可以改善这种作用。在MI大鼠模型中注射CFD-IN1证实抑制CFD活性减轻了心肌细胞凋亡。
    我们的发现表明EAT通过分泌CFD和激活PARP-1活性介导MI后心肌细胞凋亡。
    Acute myocardial infarction (MI) is considered to be the main cause of congestive heart failure. The aim of this study was to provide an in-depth analysis of athophysiological processes and provide key targets for intervention in the occurrence of acute MI.
    A rat model of MI was established by ligation of left anterior descending branch. Heart tissue, epicardial adipose tissue (EAT) and subcutaneous adipose tissue (SAT) were collected. H9c2 cells were used to explore the mechanism of complement factor D (CFD) regulating cardiomyocyte apoptosis.
    Myocardial apoptosis were observed in MI rat, and more EAT was found in the MI group in vivo. The conditioned medium prepared by EAT (EAT-CM) significantly reduced the activity of H9c2 cells. The content of CFD in EAT was significantly increased, and CFD promoted cardiomyocyte apoptosis in vitro and CFD-IN1 (a selective inhibitor of CFD) could revised this effect. CFD induced poly ADP-ribosepolymerase-1 (PARP-1) overactivation. Furthermore, the addition of pan-caspase inhibitor Z-VAD in the SAT-CM + CFD group couldn\'t affect H9c2 cell apoptosis. CFD induced cell apoptosis via PARP-1 activation and PARP-1 inhibitor 3-Aminobenzamide could revise this effect. The injection of CFD-IN1 in MI rat model confirmed that inhibition of CFD activity alleviated cardiomyocytes apoptosis.
    Our findings indicate that EAT mediating cardiomyocyte apoptosis after MI through secretion of CFD and activation of PARP-1 activity.

    UNASSIGNED: In recent years, peri-organ fat has emerged as a diagnostic and therapeutic target in metabolic diseases, including diabetes mellitus. Here, we performed a comprehensive analysis of epicardial adipose tissue (EAT) transcriptome expression differences between diabetic and non-diabetic participants and explored the possible mechanisms using various bioinformatic tools.
    UNASSIGNED: RNA-seq datasets GSE108971 and GSE179455 for EAT between diabetic and non-diabetic patients were obtained from the public functional genomics database Gene Expression Omnibus (GEO). The differentially expressed genes (DEGs) were identified using the R package DESeq2, then Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were analyzed. Next, a PPI (protein-protein interaction) network was constructed, and hub genes were mined using STRING and Cytoscape. Additionally, CIBERSORT was used to analyze the immune cell infiltration, and key transcription factors were predicted based on ChEA3.
    UNASSIGNED: By comparing EAT samples between diabetic and non-diabetic patients, a total of 238 DEGs were identified, including 161 upregulated genes and 77 downregulated genes. A total of 10 genes (IL-1β, CD274, PDCD1, ITGAX, PRDM1, LAG3, TNFRSF18, CCL20, IL1RN, and SPP1) were selected as hub genes. GO and KEGG analysis showed that DEGs were mainly enriched in the inflammatory response and cytokine activity. Immune cell infiltration analysis indicated that macrophage M2 and T cells CD4 memory resting accounted for the largest proportion of these immune cells. CSRNP1, RELB, NFKB2, SNAI1, and FOSB were detected as potential transcription factors.
    UNASSIGNED: Comprehensive bioinformatic analysis was used to compare the difference in EAT between diabetic and non-diabetic patients. Several hub genes, transcription factors, and immune cell infiltration were identified. Diabetic EAT is significantly different in the inflammatory response and cytokine activity. These findings may provide new targets for the diagnosis and treatment of diabetes, as well as reduce potential cardiovascular complications in diabetic patients through EAT modification.

    过量的碘可导致女性自身免疫性甲状腺炎(AIT),但目前尚不清楚这是否对后代的神经发育机制有任何影响。我们通过脑源性神经营养因子(BDNF)-原霉素受体激酶B(TrkB)信号通路研究了不同碘摄入量的实验性自身免疫性甲状腺炎(EAT)大鼠对后代脑发育的影响,因为BDNF在神经发育中起着重要作用。三个甲状腺球蛋白(Tg)免疫组的大鼠具有不同的碘摄入量(Tg(100µg/L碘),Tg+高碘I组(Tg+HI,20毫克/升碘),和Tg+高碘II组(Tg+HII,200mg/L碘))每2周一次注射800µgTg,共3次。对照组大鼠(NI,100µg/L碘)用盐水免疫。砷铈催化分光光度法用于测量尿碘水平。通过组织病理学研究观察到甲状腺中的淋巴细胞浸润。使用放射免疫分析法测量甲状腺自身抗体水平。通过酶联免疫吸附测定法测量去甲肾上腺素(NE)含量。采用实时定量PCR和Westernblot检测BDNF-TrkB信号通路及相关基因水平。尿碘水平随着碘摄入量的增加而增加。Tg免疫大鼠淋巴细胞明显加重。在Tg免疫的大鼠中,血清甲状腺球蛋白抗体(TgAb)和甲状腺过氧化物酶抗体(TPOAb)水平明显升高。Tg-免疫组具有显著较低的NE水平。在碘水平较高的Tg免疫组中,BDNF-TrkB信号通路和相关基因mRNA和蛋白水平显着降低。母亲AIT可能会降低后代某些神经发育机制的水平,如BDNF-TrkB信号通路及相关因素,而母亲过量摄入碘可能会加剧这种影响。
    Excess iodine can cause autoimmune thyroiditis (AIT) in women, but it is unclear whether this has any implications for neurodevelopmental mechanisms in offspring. We studied the effects of experimental autoimmune thyroiditis (EAT) rats with different amounts of iodine intake on offspring brain development via the brain-derived neurotrophic factor (BDNF)-tropomycin receptor kinase B (TrkB) signaling pathway, because BDNF plays an important role in neurodevelopment. Rats in three thyroglobulin (Tg) immunized groups with varying iodine intakes (Tg (100 µg/L iodine), Tg + High-iodine I group (Tg + HI, 20 mg/L iodine), and Tg + High-iodine II group (Tg + HII, 200 mg/L iodine)) were injected with 800 µg Tg once every 2 weeks for 3 times. Rats in the control group (NI, 100 µg/L iodine) were immunized with saline. Arsenic-cerium catalytic spectrophotometry was used to measure urine iodine levels. The lymphocytic infiltration in the thyroids was observed by histopathological studies. Thyroid autoantibodies levels were measured using radioimmunoassay. The norepinephrine (NE) contents were measured by an enzyme-linked immunosorbent assay. The levels of the BDNF-TrkB signaling pathway and related genes were measured by quantitative real-time PCR and Western blot. Urinary iodine levels increased as iodine intake increased. Lymphocytes were significantly aggravated in Tg-immunized rats. Serum thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) levels were clearly elevated in Tg-immunized rats. Tg-immune groups had significantly lower NE levels. The BDNF-TrkB signaling pathway and related gene mRNA and protein levels were found to be significantly lower in Tg-immune groups with higher iodine levels. Maternal AIT may reduce the levels of certain neurodevelopmental mechanisms in the offspring, such as the BDNF-TrkB signaling pathway and related factors, while excessive iodine consumption by the mother may exacerbate this effect.

    背景:心外膜脂肪组织(EAT)被认为是可直接影响冠状动脉的生物活性分子的重要来源,并且与阻塞性冠状动脉狭窄和心肌缺血的同时存在有关。非酒精性脂肪性肝病(NAFLD)已成为全球范围内的新兴健康问题。
    目的:本横断面研究旨在探讨普通人群中EAT用量与NAFLD及其他心血管危险因素之间的关系。
    方法:在本研究中,我们从唐山冀东社区中选取了2338名年龄在40岁以上的参与者,中国。64层CT检查EAT体积,肝脏超声检查用于NAFLD的诊断。根据EAT体积比较研究队列。
    结果:心血管危险因素,如冠状动脉钙评分,颈动脉内膜中层厚度,NAFLD,理想的心血管健康指标也被发现与EAT相关。在多变量逻辑回归分析中,NAFLD组显示出与较高EAT量的显著关联,纠正主要心血管疾病危险因素后(OR[95%CI],1.407[1.117,1.773])。
    结论:我们在普通社区人群中的发现提供了证据,证明EAT与NAFLD和其他心血管危险因素密切相关。
    BACKGROUND: Epicardial adipose tissue (EAT) is considered an important source of bioactive molecules that can influence coronary arteries directly and is related to the concurrent presence of both obstructive coronary stenosis and myocardial ischemia independently. Non-alcoholic fatty liver disease (NAFLD) has become an emergent health problem worldwide.
    OBJECTIVE: This cross-sectional study aimed to address the relationship between the volume of EAT and NAFLD and other cardiovascular risk factors in the general population.
    METHODS: In this study, we selected a total of 2,238 participants aged at least 40 years from the Jidong community in Tangshan, China. The 64-slice CT was used to survey the volume of EAT and liver ultrasonography was used for the diagnosis of NAFLD. The study cohorts were compared according to EAT volume.
    RESULTS: Cardiovascular risk factors, such as coronary artery calcium score, carotid intima-media thickness, NAFLD, and ideal cardiovascular health metrics were also found to be related to EAT. In multivariate logistic regression analysis, NAFLD groups showed significant association with higher EAT volume, after correcting for main cardiovascular disease risk factors (OR [95% CI], 1.407 [1.117, 1.773]).
    CONCLUSIONS: Our findings in a general community population provide evidence that EAT is strongly associated with NAFLD and other cardiovascular risk factors.

    桥本甲状腺炎(HT)是最常见的器官特异性自身免疫性疾病之一。越来越多的证据表明,HT的特征可能是辅助T细胞亚群Th1和Th2的失衡。中医(TCM)认为HT是一种慢性衰竭疾病,导致气虚。在中医,气表示人体器官的功能力;因此,中医建议重点治疗HT,以增加气的产生。人参是一种著名的草药,具有多种功效,它的主要功能是产生气。人参的主要活性成分是人参皂苷,和现代药理学表明,人参皂苷具有双相免疫调节作用,可用于治疗免疫疾病。以前的工作表明,人参皂苷对HT有治疗作用,但其机制未知。为了研究人参皂苷是否可以调节Th1/Th2失衡,制作实验性自身免疫性甲状腺炎大鼠。直接目的是通过ELISA检查IFN-γ和IL-4的调节,并通过实时PCR和Westernblot检测T-bet和GATA-3的基因和蛋白表达。EAT大鼠IFN-γ水平升高,IL-4水平降低;人参皂苷治疗导致外周血IFN-γ水平降低,低剂量具有统计学意义。人参皂苷对IL-4产生双相作用,低剂量和中等剂量促进分泌,高剂量抑制分泌。T-bet的蛋白质和mRNA水平均明显降低,而GATA-3显著增加人参皂苷。
    Hashimoto\'s thyroiditis (HT) is one of the most common organ-specific autoimmune diseases. Increasing evidence indicates that HT may be characterized by an imbalance in the helper T cell subsets Th1 and Th2. Traditional Chinese Medicine (TCM) considers HT as a chronic exhaustion disease, leading to deficiency of qi. In TCM, qi indicates the functional power of the organs of the human body; hence TCM recommends focusing the treatment of HT so as to increase qi production. Ginseng is a well-known herbal medicine exhibiting a variety of efficacies, its main function-being to generate qi. Ginseng\'s principal active component is ginsenoside, and modern pharmacology has shown that ginsenoside demonstrates biphasic immunomodulatory effects that can be utilized for the treatment of immune disorders. Previous work demonstrated that ginsenoside has a therapeutic effect on HT, but its mechanism is unknown. Experimental autoimmune thyroiditis rats were produced in order to investigate whether ginsenoside can modulate Th1/Th2 imbalance, the direct objective being to examine modulation of IFN-γ and IL-4 by ELISA, and the gene and protein expression of T-bet and GATA-3 by real-time PCR and Western blot. IFN-γ levels were increased while IL-4 levels decreased in EAT rats; treatment with ginsenoside led to decreased peripheral blood IFN-γ levels, with low doses statistically significant. Ginsenoside produced a biphasic effect on IL-4, with low and moderate doses promoting and high doses inhibiting secretion. Both protein and mRNA levels of T-bet were markedly reduced, while GATA-3 was significantly increased by ginsenoside.
