Background and aims

Advanced hepatocellular carcinoma (HCC) with pulmonary metastasis (PM) has a poor prognosis, and optimal treatment strategies remain controversial. This study aimed to compare the long-term outcomes of patients with advanced HCC with PM who were treated with resection of pulmonary metastases versus those treated with targeted therapies combined with immunotherapy.

Methods

A retrospective analysis was conducted on the medical records of HCC patients with PM who underwent either pulmonary metastasectomy or immunotherapy combined with targeted therapies at the Eastern Hepatobiliary Surgery Hospital, Changhai Hospital of Shanghai, Fujian Provincial Hospital, and West China Hospital of Sichuan University from September 2013 to October 2022. One-to-one propensity score matching (PSM) was employed to control the influence of potential confounders, and the survival outcomes were compared.

Results

A total of 119 HCC patients with PM were included in this study. The overall survival (OS) of patients who underwent pulmonary metastasectomy was significantly longer than that of patients who received immunotherapy targeted combinations (OS: 1-year, 80.0% vs. 59.3%; 2-year, 31.7% vs. 20.3%; 3-year, 20.0% vs. 0; P < 0.001). After PSM, the long-term prognosis of the pulmonary metastasectomy group remained significantly better than that of the immunotherapy combination group (OS: 1-year, 87.0% vs. 69.6%; 2-year, 34.8% vs. 30.4%; 3-year, 21.7% vs. 0; P = 0.005). Multivariate analysis revealed that treatment allocation (hazard ratio (HR) = 2.177, 95% confidence interval (CI) = 1.068–4.439) and hepatic tumor T stage (HR = 2.342, 95% CI = 1.209–4.538) were independent risk factors for OS.

Conclusions

Pulmonary metastasectomy was associated with improved survival compared to immunotherapy combined with targeted therapies and may represent an optimal treatment option for highly selected HCC patients with resectable PM.
背景与目的晚期肝细胞癌(HCC)合并肺转移(PM)预后较差,其最佳治疗策略仍存在争议。本研究旨在比较晚期HCC合并PM患者接受肺转移切除治疗与靶向治疗联合免疫治疗的长期预后。方法回顾性分析2013年9月至2022年10月在上海东部肝胆外科医院、上海长海医院、福建省立医院和四川大学华西医院接受肺转移切除术或免疫联合靶向治疗的肝癌合并PM患者的病历。采用一对一倾向评分匹配(PSM)来控制潜在混杂因素的影响,并比较生存结果。结果本研究共纳入119例HCC合并PM患者。接受肺转移瘤切除术的患者的总生存期(OS)明显长于接受靶向免疫治疗联合治疗的患者(OS: 1年,80.0% vs. 59.3%;2年,31.7% vs. 20.3%;3年,20.0% vs. 0;P & lt;0.001)。PSM后,肺转移瘤切除术组的长期预后仍显著优于免疫治疗联合组(OS: 1年,87.0% vs 69.6%;2年,34.8% vs. 30.4%;3年,21.7% vs. 0;p = 0.005)。多因素分析显示,治疗分配(风险比(HR) = 2.177, 95%可信区间(CI) = 1.068 ~ 4.439)和肝肿瘤T分期(HR = 2.342, 95% CI = 1.209 ~ 4.538)是发生OS的独立危险因素。结论与免疫治疗联合靶向治疗相比,肺转移切除术可提高生存率,可能是高选择性肝癌患者可切除PM的最佳治疗选择。

Background and aims

Studies indicate that the gut microbiota and its metabolites are involved in the progression of cardiovascular diseases, and enterohepatic circulation plays an important role in this progression. This study aims to identify potential probiotics for the treatment of unstable angina (UA) and elucidate their mechanisms of action.

Methods

Initially, the gut microbiota from patients with UA and control was analyzed. To directly assess the effects of Bifidobacterium supplementation, 10 patients with UA were enrolled and administered Bifidobacterium (630 mg per intake twice a day for 1 month). The fecal metagenome, serum trimethylamine N-oxide (TMAO) levels, and other laboratory parameters were evaluated before and after Bifidobacterium supplementation.

Results

After supplementing with Bifidobacterium for 1 month, there were statistically significant differences (P < 0.05) in TMAO, aspartate aminotransferase, total cholesterol, and low-density lipoprotein compared to before. Additionally, the abundance of Bifidobacterium longum increased significantly, although the overall abundance of Bifidobacterium did not reach statistical significance. The gut microbiota, metabolites, and gut-liver axis are involved in the progression of UA, and potential mechanisms should be further studied.

Conclusions

Metagenomic analysis demonstrated a reduced abundance of Bifidobacterium in patients with UA. Supplementation with Bifidobacterium restored gut dysbiosis and decreased circulating TMAO levels in patients with UA. This study provides evidence that Bifidobacterium may exert cardiovascular-protective effects through the gut–liver–heart axis.

背景与目的研究表明,肠道菌群及其代谢产物参与心血管疾病的进展,而肠肝循环在这一过程中起着重要作用。本研究旨在鉴定治疗不稳定型心绞痛的潜在益生菌,并阐明其作用机制。方法首先对UA患者和对照组的肠道菌群进行分析。为了直接评估补充双歧杆菌的效果,招募了10名UA患者,并给予双歧杆菌(每次摄入630毫克,每天两次,持续1个月)。在补充双歧杆菌前后评估粪便宏基因组、血清三甲胺n -氧化物(TMAO)水平和其他实验室参数。结果补充双歧杆菌1个月后,差异有统计学意义(P <;TMAO、天冬氨酸转氨酶、总胆固醇、低密度脂蛋白与治疗前比较0.05)。此外,长双歧杆菌的丰度也显著增加,尽管双歧杆菌的总体丰度没有达到统计学意义。肠道菌群、代谢物和肠肝轴参与UA的进展,其潜在机制有待进一步研究。结论宏基因组分析显示UA患者双歧杆菌丰度降低。补充双歧杆菌可恢复UA患者的肠道生态失调并降低循环TMAO水平。这项研究提供了双歧杆菌可能通过肠-肝-心轴发挥心血管保护作用的证据。临床试验编号chictr2400093946。

Extracellular vesicles (EVs) are membrane-bound entities secreted by each cell, categorized as, exosomes, microvesicles or apoptotic bodies based on their size and biogenesis. They serve as promising vectors for drug delivery due to their capacity to carry diverse molecular signatures reflective of their cell of origin. EV research has significantly advanced since their serendipitous discovery, with recent studies focusing on their roles in various diseases and their potential for targeted therapy. In liver diseases, EVs are particularly promising for precision medicine, providing diagnostic and therapeutic potential in conditions such as metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction-associated steatohepatitis, hepatocellular carcinoma, alcoholic liver disease, liver fibrosis, and acute liver failure. Despite challenges in isolation and characterization, engineered EVs have shown efficacy in delivering therapeutic agents with improved targeting and reduced side effects. As research progresses, EVs hold great promise to revolutionize precision medicine in liver diseases, offering targeted, efficient, and versatile therapeutic options. In this review, we summarize various techniques for loading EVs with therapeutic cargo including both passive and active methods, and the potential of bioengineered EVs loaded with various molecules, such as miRNAs, proteins, and anti-inflammatory drugs in ameliorating clinical pathologies of liver diseases.
细胞外囊泡(EVs)是由每个细胞分泌的膜结合实体,根据其大小和生物起源可分为外泌体、微囊泡或凋亡小体。由于它们能够携带反映其来源细胞的各种分子特征,因此它们是很有希望的药物递送载体。自其偶然发现以来,EV研究取得了显著进展,最近的研究重点是它们在各种疾病中的作用及其靶向治疗的潜力。在肝脏疾病方面,电动汽车在精准医学方面尤其有前景,在代谢功能障碍相关的脂肪性肝病和代谢功能障碍相关的脂肪性肝炎、肝细胞癌、酒精性肝病、肝纤维化和急性肝衰竭等疾病中提供诊断和治疗潜力。尽管在分离和表征方面存在挑战,但经过改造的电动汽车已经显示出在递送治疗药物方面的有效性,并且具有更好的靶向性和更少的副作用。随着研究的进展,电动汽车有望彻底改变肝病的精准医疗,提供有针对性、高效和多功能的治疗选择。在这篇综述中,我们总结了各种装载治疗性货物的技术,包括被动和主动方法,以及装载各种分子(如mirna,蛋白质和抗炎药物)的生物工程ev在改善肝脏疾病临床病理方面的潜力。

Similarly to conventional steroids, bile acids function as signaling molecules, acting on a family of membrane and nuclear receptors. The best-characterized bile acid-regulated receptors are the farnesoid X receptor, activated by primary bile acids, and the G-protein-coupled bile acid receptor 1 (also known as Takeda G protein-coupled receptor 5), which is activated by secondary bile acids, such as lithocholic acid (LCA) and deoxycholic acid. Both the farnesoid X receptor and G-protein-coupled bile acid receptor 1 are expressed in cells of innate immunity, monocytes/macrophages, and natural killer cells. Their activation in these cells provides counter-regulatory signals that are inhibitory in nature and attenuate inflammation. In recent years, however, it has been increasingly appreciated that bile acids biotransformations by intestinal microbiota result in the formation of chemically different secondary bile acids that potently regulate adaptive immunity. The 3-oxoLCA and isoalloLCA, two LCA derivatives, bind receptors such as the retinoic acid receptor-related orphan receptor gamma t (RORγt) and the vitamin D receptor (VDR) that are expressed only by lymphoid cells, extending the regulatory role of bile acids to T cells, including T-helper 17 cells and type 3 innate lymphoid cells (ILC3). In this novel conceptual framework, bile acids have emerged as one of the main components of the postbiota, the waste array of chemical mediators generated by the intestinal microbiota. Deciphering the interaction of these mediators with the immune system in the intestine and liver is a novel and fascinating area of bile acid renaissance.
与传统类固醇类似,胆汁酸作为信号分子,作用于一系列膜和核受体。最具特征的胆汁酸调节受体是farnesoid X受体,由初级胆汁酸激活,以及G蛋白偶联胆汁酸受体1(也称为武田G蛋白偶联受体5),由二级胆汁酸,如石胆酸(LCA)和脱氧胆酸激活。farnesoid X受体和g蛋白偶联胆汁酸受体1均在先天免疫细胞、单核/巨噬细胞和自然杀伤细胞中表达。它们在这些细胞中的激活提供了具有抑制性质和减轻炎症的反调节信号。然而,近年来,人们越来越认识到肠道微生物群对胆汁酸的生物转化会导致化学上不同的次级胆汁酸的形成,从而有效地调节适应性免疫。3- oxolca和isoalloLCA是两种LCA衍生物,结合仅由淋巴样细胞表达的视黄酸受体相关孤儿受体γt (RORγt)和维生素D受体(VDR)等受体,将胆汁酸的调节作用扩展到t细胞,包括t辅助17细胞和3型先天淋巴样细胞(ILC3)。在这个新的概念框架中,胆汁酸已成为后生物群的主要组成部分之一,后生物群是由肠道微生物群产生的化学介质的废物阵列。破译这些介质与肠道和肝脏免疫系统的相互作用是胆汁酸复兴的一个新颖而迷人的领域。

<div><h3>Background and aims</h3><div>Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, and its etiology involves a complex interplay of genetic and environmental factors. Despite advancements in our understanding of HCC biology and the development of novel therapeutic strategies, the molecular mechanisms underlying its onset, progression, and resistance to therapy remain largely vague. This study aimed to investigate the role of mechanosensitive ion channel-related genes (MICRGs) in HCC, focusing on their potential as prognostic biomarkers and their involvement in immune modulation and drug resistance.</div></div><div><h3>Methods</h3><div>A comprehensive analysis was conducted using The Cancer Genome Atlas database to identify MICRGs that are upregulated in HCC. Gene expression profiling, bioinformatics tools, and functional experiments were employed to elucidate the role of these channels. In addition, protein–protein interaction (PPI) network analyses and enrichment analyses were performed to explore the biological significance of these genes. An immune cell infiltration analysis was also conducted to understand MICRG-related immune landscape. Single-cell RNA sequencing (scRNA-seq) data were utilized to identify MICRGs in different cell types within the HCC tissue. Deep-learning neural network analysis across patient cohorts was conducted to identify genes associated with sorafenib resistance. Knockdown experiments, cell viability assays, and apoptosis assays on HCC cell lines were performed to examine the role of Piezo-type mechanosensitive ion channel component 1 (<em>PIEZO1</em>) in sorafenib resistance.</div></div><div><h3>Results</h3><div>The analysis identified a subset of MICRGs, including <em>PIEZO1</em>, that were significantly upregulated in HCC and associated with poor prognosis. The PPI network analysis revealed complex interactions among these genes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses proposed the involvement of these genes in calcium signaling pathways. Immune cell infiltration analysis demonstrated distinct associations between MICRGs and various immune subpopulations, highlighting their potential roles in immune modulation. scRNA-seq data indicated the upregulation of MICRGs in various cell types in HCC tissues, particularly in endothelial cells and tumor-associated macrophages. Deep-learning neural network analysis across different patient cohorts identified <em>PIEZO1</em> as a crucial regulator of sorafenib resistance in HCC, which was further validated by functional assays on HCC cell lines.</div></div><div><h3>Conclusions</h3><div>This study provides evidence that MICRGs, particularly <em>PIEZO1</em>, take on crucial roles in HCC progression and drug resistance.

背景和目的肝细胞癌(HCC)是全球癌症相关死亡的主要原因,其病因涉及遗传和环境因素的复杂相互作用。尽管我们对HCC生物学的理解有了进步,新的治疗策略也有了发展,但其发病、进展和耐药的分子机制仍然很模糊。本研究旨在探讨机械敏感离子通道相关基因(MICRGs)在HCC中的作用,重点关注它们作为预后生物标志物的潜力以及它们在免疫调节和耐药性中的参与。方法利用The Cancer Genome Atlas数据库进行综合分析,确定HCC中上调的MICRGs。基因表达谱、生物信息学工具和功能实验被用来阐明这些通道的作用。此外,我们还进行了蛋白-蛋白相互作用(PPI)网络分析和富集分析,以探索这些基因的生物学意义。免疫细胞浸润分析也被用来了解micrg相关的免疫景观。单细胞RNA测序(scRNA-seq)数据用于鉴定HCC组织中不同细胞类型中的MICRGs。对患者队列进行深度学习神经网络分析,以确定与索拉非尼耐药相关的基因。通过敲低实验、细胞活力测定和细胞凋亡测定,研究压电型机械敏感离子通道成分1 (PIEZO1)在索拉非尼耐药中的作用。结果分析发现,包括PIEZO1在内的MICRGs亚群在HCC中显著上调,并与预后不良相关。PPI网络分析揭示了这些基因之间复杂的相互作用。基因本体和京都基因与基因组百科全书路径富集分析提出这些基因参与钙信号通路。免疫细胞浸润分析显示,MICRGs与各种免疫亚群之间存在明显的关联,突出了它们在免疫调节中的潜在作用。scRNA-seq数据显示,HCC组织中各种细胞类型中MICRGs表达上调,尤其是内皮细胞和肿瘤相关巨噬细胞。对不同患者队列的深度学习神经网络分析发现,PIEZO1是HCC中索拉非尼耐药的关键调节因子,并通过HCC细胞系的功能分析进一步验证了这一点。本研究提供证据表明,MICRGs,特别是PIEZO1,在HCC的进展和耐药中起着至关重要的作用。HCC细胞中PIEZO1的上调与预后不良和索拉非尼耐药有关。这些发现表明,PIEZO1可以作为HCC中克服耐药的潜在治疗靶点和预后生物标志物。未来的研究应侧重于在更大的患者群体中验证这些发现,并在临床前模型中探索靶向PIEZO1的功能意义。

Background and aims

Hepatocellular carcinoma (HCC) is a malignant tumor with a high mortality rate, but there are still no effective treatments. The aim of this study was to investigate the anticancer potential of the combined use of brefeldin A (BFA) and tunicamycin (TM) in HepG2 cells, as well as the underlying mechanisms.

Methods

HepG2 cells were treated with different concentrations of BFA (0.1–2.5 mg/L) and TM (1–5 mg/L) for 24 h. DMSO (0.1 %, v/v) was used as a vehicle control. Cell viability and cell migration were measured using MTT assay and scratch wound assay, respectively. Apoptosis was detected using flow cytometry and acridine orange (AO) staining. The protein and mRNA levels of various factors involved in apoptosis (poly (ADP-ribose) polymerase-1 (PARP-1), caspase-12, caspase-3, and stearoyl-CoA desaturase 1) and endoplasmic reticulum (ER) stress (binding immunoglobulin protein (BiP), protein kinase R-like endoplasmic reticulum kinase (PERK), p-PERK, phosphorylation of eukaryotic translation initiation factor 2alpha (p-eIF2α), activating transcription factor (ATF) 4, and C/EBP homologous protein (CHOP)) were measured using Western blotting and qRT-PCR, respectively.

Results

Both BFA and TM alone significantly reduced the viability of HepG2 cells in a dose-dependent way. The co-incubation with TM (1 mg/L) further significantly reduced the viability of HepG2 cells treated with BFA (0.25 mg/L) alone (P < 0.05). BFA significantly increased the protein and mRNA levels of caspase-3 and PARP-1 (P < 0.05) compared to control and DMSO-treated cells, indicating that BFA induced apoptosis in HepG2 cells by increasing the expression of caspase-3 and PARP-1. The induction of apoptosis by BFA could be further significantly enhanced by co-incubation with TM. In addition, BFA significantly increased the mRNA levels of BiP, PERK and ATF4 (P < 0.05) compared to control and DMSO-treated cells. After co-incubation of BFA and TM, the protein levels of BiP, p-PERK, p-eIF2α and CHOP were significantly increased, indicating that TM could enhance BFA-induced ER stress in HepG2 cells through the PERK-eIF2α-ATF4-CHOP pathway.

Conclusions

BFA could induce apoptosis and ER stress, and TM could enhance the ability of BFA to induce apoptosis and ER stress in HepG2 cells through the PERK-eIF2ɑ-ATF4-CHOP pathway. The findings highlight the therapeutic potential of the combined use of BFA and TM in treating HCC.
背景与目的肝细胞癌(HCC)是一种死亡率高的恶性肿瘤,目前尚无有效的治疗方法。本研究的目的是探讨brefeldin A (BFA)和tunicamycin (TM)联合使用在HepG2细胞中的抗癌潜力及其潜在机制。方法用不同浓度的BFA (0.1 ~ 2.5 mg/L)和TM (1 ~ 5 mg/L)处理shepg2细胞24 h,以DMSO (0.1%, v/v)作为对照。分别采用MTT法和抓伤法测定细胞活力和细胞迁移量。流式细胞术和吖啶橙(AO)染色检测细胞凋亡。参与细胞凋亡的各种因子(聚(adp -核糖)聚合酶1 (PARP-1)、caspase-12、caspase-3和硬脂酰辅酶a去饱和酶1)和内质网(ER)应激(结合免疫球蛋白蛋白(BiP)、蛋白激酶r样内质网激酶(PERK)、p-PERK、真核翻译起始因子2α (p-eIF2α)磷酸化、激活转录因子(ATF) 4、分别采用Western blotting和qRT-PCR检测C/EBP同源蛋白(CHOP)。结果BFA和TM均能显著降低HepG2细胞活力,且呈剂量依赖性。与TM (1 mg/L)共孵育进一步显著降低BFA (0.25 mg/L)单独处理HepG2细胞的活力(P <;0.05)。BFA显著提高了caspase-3和PARP-1的蛋白和mRNA水平(P <;0.05),表明BFA通过增加caspase-3和PARP-1的表达诱导HepG2细胞凋亡。BFA与TM共孵育可进一步显著增强BFA对细胞凋亡的诱导作用。此外,BFA显著提高了BiP、PERK和ATF4 mRNA水平(P <;0.05),与对照组和dmso处理的细胞相比。BFA与TM共孵生后,BiP、p-PERK、p-eIF2α和CHOP蛋白水平均显著升高,说明TM可通过PERK-eIF2α-ATF4-CHOP通路增强BFA诱导的HepG2细胞内质网应激。结论sbfa可诱导HepG2细胞凋亡和内质网应激,而TM可通过PERK-eIF2 -ATF4-CHOP通路增强BFA诱导HepG2细胞凋亡和内质网应激的能力。研究结果强调了联合使用BFA和TM治疗HCC的治疗潜力。

Background and aims

Kehuang (KH) capsule is an herbal medical product approved for the treatment of liver diseases, including liver injury, in China. However, the mechanism is still unclear. This study aimed to elucidate the protective effects of KH capsule against carbon tetrachloride (CCl4)-induced acute liver injury (ALI) in a murine model.

Methods

Mice were randomly divided into control, model (CCl4), CCl4+KH_Low and CCl4+KH_High group. Liver enzyme levels and histological changes were assessed to evaluate liver injury. Oxidative stress markers and inflammatory cell infiltration in liver tissues were measured. Additionally, network pharmacology was employed to explore the potential mechanisms of KH capsule.

Results

KH capsule significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, as well as the necrotic area in liver tissue. KH capsule also decreased the infiltration of macrophages and neutrophils, thereby inhibiting the expression of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β). Furthermore, KH capsule decreased liver malondialdehyde (MDA) levels and increased superoxide dismutase (SOD) activity. The number of terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL)-positive cells in liver tissue was also reduced. The expression of nuclear factor erythroid 2 related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) proteins was significantly elevated, while the protein expression of cytochrome P450 2E1 (CYP2E1) was significantly reduced. Mass spectrometry identified genistein, galangin, wogonin, skullcapflavone II, and hispidulin as potential active ingredients of KH capsule. Network pharmacology analysis revealed enrichment in the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K)-protein kinase B (AKT) signaling pathways. Western blot analysis confirmed that KH capsule suppressed AKT, extracellular signal-regulated kinase (ERK), and p38 signaling.

Conclusions

These findings suggest that KH capsule could exert protective effects against CCl4-induced ALI, with the inhibition of MAPK and PI3K-AKT signaling pathways playing a crucial role in its mechanism of action.

Liver transplantation remains the most effective treatment for end-stage liver disease (ESLD), but it is fraught with challenges such as immunosuppression, high risk and cost, and donor shortage. In recent years, stem cell transplantation has emerged as a promising new strategy for ESLD treatment, with mesenchymal stem cells (MSCs) gaining significant attention because of their unique properties. MSCs can regulate signaling pathways, including hepatocyte growth factor/c-Met, Wnt/beta (β)-catenin, Notch, transforming growth factor-β1/Smad, interleukin-6/Janus kinase/signal transducer and activator of transcription 3, and phosphatidylinositol 3-kinase/PDK/Akt, thereby influencing the progression of liver fibrosis and regeneration. As a promising stem cell type, MSCs offer numerous advantages in liver disease treatment, including low immunogenicity; ease of acquisition; unlimited proliferative ability; pluripotent differentiation potential; immunomodulatory function; and anti-inflammatory, antifibrotic, and antiapoptotic biological characteristics. This review outlines the mechanisms by which MSCs reverse liver fibrosis and promote liver regeneration. MSCs are crucial in reversing liver fibrosis and repairing liver damage through the secretion of growth factors, regulation of signaling pathways, and modulation of immune responses. MSCs have shown good therapeutic effects in preclinical and clinical studies, providing new strategies for liver disease treatment. However, challenges still exist in the clinical application of MSCs, including low differentiation efficiency and limited sources. This review provides a reference for MSC application in liver disease treatment. With the continuous progress in MSC research, MSCs are expected to achieve breakthroughs in liver disease treatment, thereby improving patient treatment outcomes.
肝移植仍然是终末期肝病(ESLD)最有效的治疗方法,但它充满了免疫抑制、高风险和高成本以及供体短缺等挑战。近年来,干细胞移植已成为治疗ESLD的一种有前景的新策略,其中间充质干细胞(MSCs)因其独特的特性而受到广泛关注。MSCs可以调节肝细胞生长因子/c-Met、Wnt/ β (β)-catenin、Notch、转化生长因子-β1/Smad、白介素-6/Janus激酶/信号转导和转录激活因子3、磷脂酰肌醇3激酶/PDK/Akt等信号通路,从而影响肝纤维化的进展和肝再生。作为一种有前景的干细胞类型,MSCs在肝脏疾病治疗中具有许多优势,包括低免疫原性;易于获取;无限的增殖能力;多能分化潜能;免疫调节功能;并具有抗炎、抗纤维化、抗细胞凋亡的生物学特性。本文综述了MSCs逆转肝纤维化和促进肝再生的机制。间充质干细胞通过分泌生长因子、调节信号通路和调节免疫反应,在逆转肝纤维化和修复肝损伤方面发挥着至关重要的作用。MSCs在临床前和临床研究中均显示出良好的治疗效果,为肝脏疾病的治疗提供了新的策略。然而,MSCs在临床应用中仍存在分化效率低、来源有限等挑战。本文综述为MSC在肝脏疾病治疗中的应用提供参考。随着MSC研究的不断进展,MSC有望在肝病治疗方面取得突破,从而改善患者的治疗效果。

Background and aims

Antiviral therapy is essential for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). No data are available on the long-term prognosis or safety of tenofovir alafenamide (TAF), tenofovir disoproxil fumarate (TDF), or entecavir (ETV) in treating HBV-ACLF globally. This study was conducted to investigate the long-term efficacy and safety of the three nucleos(t)ide analogs in the treatment of HBV-ACLF.

Methods

In this prospective, real-world cohort study, patients with HBV-ACLF were assigned to the TAF, TDF, and ETV groups. A total of 199 patients completed the 144-week follow-up. After propensity score matching (PSM), 44 patients remained in each group for further analysis of survival status, incidence of hepatocellular carcinoma (HCC), virological response, and liver and renal function indicators.

Results

In the original cohort, HCC developed in one patient in each group. No serious drug-related adverse events were observed. In the PSM cohort, the 144-week survival rates were 56.82%, 75.00%, and 59.09% in the TAF, TDF, and ETV groups, respectively (P = 0.118). When stratified into noncirrhosis and cirrhosis subgroups at baseline, the survival rate of the ETV group was slightly lower than that of the TAF and TDF group in noncirrhosis patients (P = 0.338), and the survival rate of the TAF group was slightly lower than that of the TDF and ETV group in cirrhosis patients (P = 0.052), but the differences were not statistically significant. The long-term overall survival rates in the TAF, TDF, and ETV groups were comparable. After 144 weeks, no significant difference in the virological response rate or liver or renal function indicators was found among the three groups, except for the level of aspartate aminotransferase, which was significantly higher in the TDF group than in the ETV group at week 144 (P = 0.001).

Conclusions

There were no significant differences in the survival rate, incidence of HCC, efficacy or safety associated with the use of these three nucleos(t)ide analogs in treating HBV-ACLF.

Trial registration

ClinicalTrials.gov NCT03920618.
背景和目的抗病毒治疗对乙型肝炎病毒相关的急性慢性肝衰竭(HBV-ACLF)至关重要。在全球范围内,没有关于替诺福韦(TAF)、富马酸替诺福韦(TDF)或恩替卡韦(ETV)治疗HBV-ACLF的长期预后或安全性的数据。本研究旨在探讨三种核苷类似物治疗HBV-ACLF的长期疗效和安全性。方法在这项前瞻性、现实世界队列研究中,HBV-ACLF患者被分配到TAF、TDF和ETV组。共有199名患者完成了144周的随访。倾向评分匹配(PSM)后,每组剩余44例患者进一步分析生存状况、肝细胞癌(HCC)发生率、病毒学反应和肝肾功能指标。结果在初始队列中,每组均有1例患者发生HCC。未观察到严重的药物相关不良事件。在PSM队列中,TAF、TDF和ETV组144周生存率分别为56.82%、75.00%和59.09% (P = 0.118)。基线分无肝硬化亚组和肝硬化亚组时,ETV组在无肝硬化患者中的生存率略低于TAF和TDF组(P = 0.338), TAF组在肝硬化患者中的生存率略低于TDF和ETV组(P = 0.052),但差异无统计学意义。TAF组、TDF组和ETV组的长期总生存率具有可比性。144周后,除了TDF组的天冬氨酸转氨酶水平显著高于ETV组(P = 0.001)外,三组间病毒学应答率及肝肾功能指标均无显著差异(P = 0.001)。结论使用这三种核苷类似物治疗HBV-ACLF在生存率、HCC发生率、疗效和安全性方面无显著差异。临床试验注册:clinicaltrials .gov NCT03920618。
