The reprogramming of lipid metabolism serves an important role in occurrence and development of liver cancer. Fatty acid hydroxylase domain containing 2 (FAXDC2) is a hydroxylase involved in the synthesis of cholesterol and sphingomyelin and downregulated in various types of cancer. There are no reports on the relationship between FAXDC2 and liver carcinogenesis. The present study used multiple portals and publicly available tools to explore its correlation with liver cancer. The results showed that the expression of FAXDC2 decreased in liver cancer and the methylation level near the promoter increased. Patients with liver cancer and with low expression of FAXDC2 had a poor prognosis. Gain of function and loss of function strategies were performed to evaluate its roles in liver cancer cells. CCK-8 assay showed that overexpression of FAXDC2 inhibited the viability of liver cancer cells (HepG2). Flow cytometry analysis indicated that HepG2 cells with overexpressing FAXDC2 showed an S phase arrest, associated with cyclin-dependent kinase 2 decreased. Transwell experiments showed that increasing FAXDC2 inhibited HepG2 cell invasion ability, accompanied by the upregulation of E-cadherin. Notably, knockdown of FAXDC2 had no significant effect on cell cycle and invasion functions. Based on the cBioPortal platform, FAXDC2 was predicted to closely correlate to the ERK signal in tumorigenesis. Western blotting results showed that overexpression of FAXDC2 decreased the phosphorylation level of ERK in liver cancer cells. The present study first identified FAXDC2 as a liver cancer suppressor, which might inhibit the proliferation and invasion of liver cancer cells through the mechanism associated with ERK signaling. The present study provided a possible new target for the diagnosis and treatment of liver cancer.
脂质代谢的重编程在肝癌的发生和发展中起着重要作用。含脂肪酸羟化酶结构域 2(FAXDC2)是一种羟化酶,参与胆固醇和鞘磷脂的合成,在多种癌症中被下调。目前还没有关于FAXDC2与肝癌发生关系的报道。本研究利用多种门户网站和公开工具探讨其与肝癌的相关性。结果显示,FAXDC2在肝癌中的表达量降低,启动子附近的甲基化水平升高。FAXDC2低表达的肝癌患者预后较差。为了评估FAXDC2在肝癌细胞中的作用,研究人员采用了功能获得和功能丧失策略。CCK-8检测表明,FAXDC2的过表达抑制了肝癌细胞(HepG2)的活力。流式细胞术分析表明,过表达FAXDC2的HepG2细胞出现S期停滞,与细胞周期蛋白依赖性激酶2的减少有关。Transwell实验表明,FAXDC2的增加抑制了HepG2细胞的侵袭能力,并伴随着E-cadherin的上调。值得注意的是,敲除FAXDC2对细胞周期和侵袭功能没有明显影响。基于cBioPortal平台,FAXDC2被预测与肿瘤发生过程中的ERK信号密切相关。Western印迹结果显示,过表达FAXDC2可降低肝癌细胞中ERK的磷酸化水平。本研究首次发现FAXDC2是一种肝癌抑制因子,它可能通过与ERK信号相关的机制抑制肝癌细胞的增殖和侵袭。本研究为肝癌的诊断和治疗提供了一个可能的新靶点。

Inflammation is involved in the pathological process underlying a number of liver diseases. Bilobalide (BB) is a natural compound from Ginkgo biloba leaves that was recently demonstrated to exert hepatoprotective effects by inhibiting oxidative stress in the liver cancer cell line HepG2. The anti-inflammatory activity of BB has been reported in recent studies. The major objective of the present study was to investigate whether BB could attenuate inflammation-associated cell damage. HepG2 cells were cultured with lipopolysaccharide (LPS) and BB, and cell damage was evaluated by measuring cell viability using MTT assay. The activity of the NF-κB signaling pathway was assessed by measuring the levels of IκBα, NF-κB p65, phosphorylated (p)-IκBα, p-p65, p65 DNA-binding activity and inflammatory cytokines IL-1β, IL-6 and TNF-α. A toll-like receptor (TLR)4 inhibitor (CLI-095) was used to detect the involvement of TLR4 in cell injury caused by LPS. In addition, the PI3K/Akt inhibitor LY294002 was applied to explore the involvement of the PI3K/Akt axis in mediating the effects of BB. The results demonstrated that LPS induced HepG2 cell injury. LPS also elevated the levels of p-IκBα, p-p65, p65 DNA-binding activity and inflammatory cytokines. However, CLI-095 significantly attenuated the LPS-induced cell damage and inhibited the activation of NF-κB signaling. BB also dose-dependently attenuated the LPS-induced cell damage, activation of NF-κB signaling and TLR4 overexpression. Furthermore, it was observed that LY294002 diminished the cytoprotective effects of BB on cell injury, TLR4 expression and NF-κB activation. These findings indicated that BB could attenuate LPS-induced inflammatory injury to HepG2 cells by regulating TLR4-NF-κB signaling.
炎症参与了多种肝病的病理过程。比罗巴内酯(BB)是从银杏叶中提取的一种天然化合物,最近的研究表明,它能通过抑制肝癌细胞株 HepG2 的氧化应激发挥保肝作用。最近的研究也报道了 BB 的抗炎活性。本研究的主要目的是探讨 BB 能否减轻炎症相关的细胞损伤。用脂多糖(LPS)和BB培养HepG2细胞,并用MTT法测定细胞活力以评估细胞损伤。通过测量 IκBα、NF-κB p65、磷酸化(p)-IκBα、p-p65、p65 DNA 结合活性以及炎症细胞因子 IL-1β、IL-6 和 TNF-α 的水平,评估了 NF-κB 信号通路的活性。使用收费样受体(TLR)4 抑制剂(CLI-095)来检测 TLR4 参与 LPS 引起的细胞损伤。此外,还使用了 PI3K/Akt 抑制剂 LY294002 来探讨 PI3K/Akt 轴参与介导 BB 的效应。结果表明,LPS 会诱导 HepG2 细胞损伤。LPS 还升高了 p-IκBα、p-p65、p65 DNA 结合活性和炎症细胞因子的水平。然而,CLI-095 能显著减轻 LPS 诱导的细胞损伤,并抑制 NF-κB 信号的激活。BB 也剂量依赖性地减轻了 LPS 诱导的细胞损伤、NF-κB 信号激活和 TLR4 过表达。此外,还观察到 LY294002 削弱了 BB 对细胞损伤、TLR4 表达和 NF-κB 激活的细胞保护作用。这些研究结果表明,BB可通过调节TLR4-NF-κB信号转导来减轻LPS诱导的HepG2细胞炎症损伤。

The present study investigated the therapeutic potential of breviscapine (Bre) in mitigating lead (Pb)-induced myocardial injury through activation of the nuclear factor erythroid-2 related factor 2 (Nrf2) pathway. Rat cardiomyocytes (H9C2 cells) were exposed to Pb to model Pb poisoning, and various parameters, including cell viability, apoptosis and reactive oxygen species (ROS) production, were assessed using Cell Counting Kit-8, flow cytometry and 2',7'-dichlorfluoresceindiacetate assays, respectively. Additionally, a rat model of Pb poisoning was established in which blood Pb levels were measured using a graphite furnace atomic absorption spectrophotometer, and alterations in myocardial tissue, oxidative stress markers, inflammatory indicators, protein expression related to apoptosis and the Nrf2 pathway were evaluated via histopathology, ELISA and western blotting. The results showed that Bre treatment enhanced cell viability, decreased apoptosis, and reduced ROS production in Pb-exposed H9C2 cells. Moreover, Bre modulated oxidative stress markers and inflammatory factors while enhancing the expression of proteins in the Nrf2 pathway. In a rat model, Bre mitigated the lead-induced increase in blood Pb levels and myocardial injury biomarkers, and reversed the downregulation of Nrf2 pathway proteins. In conclusion, the current findings suggested that Bre mitigates Pb-induced myocardial injury by activating the Nrf2 signaling pathway, highlighting its potential as a therapeutic agent for protecting the heart from the harmful effects of Pb exposure. Further research is required to elucidate the exact mechanisms and explore the clinical applicability of Bre in mitigating Pb-induced myocardial damage.
本研究探讨了布来维卡平(Bre)通过激活核因子红细胞-2相关因子2(Nrf2)通路减轻铅(Pb)诱导的心肌损伤的治疗潜力。将大鼠心肌细胞(H9C2 细胞)暴露于铅以模拟铅中毒,并使用细胞计数试剂盒-8、流式细胞仪和 2',7'-二氯荧光二乙酸盐测定法分别评估了细胞活力、凋亡和活性氧(ROS)产生等各种参数。此外,还建立了大鼠铅中毒模型,使用石墨炉原子吸收分光光度计测量血液中的铅含量,并通过组织病理学、ELISA 和 Western 印迹法评估心肌组织、氧化应激标志物、炎症指标、与细胞凋亡和 Nrf2 通路相关的蛋白质表达的变化。结果表明,Bre 处理提高了暴露于铅的 H9C2 细胞的存活率,减少了细胞凋亡,并降低了 ROS 的产生。此外,Bre 还能调节氧化应激标志物和炎症因子,同时提高 Nrf2 通路蛋白的表达。在大鼠模型中,Bre 可减轻铅引起的血液中铅含量和心肌损伤生物标志物的增加,并逆转 Nrf2 通路蛋白的下调。总之,目前的研究结果表明,Bre 可通过激活 Nrf2 信号通路减轻铅诱导的心肌损伤,突出了其作为保护心脏免受铅暴露有害影响的治疗剂的潜力。要阐明布雷在减轻铅诱导的心肌损伤方面的确切机制并探索其临床适用性,还需要进一步的研究。

BMP and activin membrane-bound inhibitor (BAMBI) is a transmembrane glycoprotein, known as a pseudo-receptor for TGFβ, as, while its extracellular domain is similar to that of type I TGFβ receptors, its intracellular structure is shorter and lacks a serine/threonine phosphokinase signaling motif. BAMBI can regulate numerous biological phenomena, including glucose and lipid metabolism, inflammatory responses, and cell proliferation and differentiation. Furthermore, abnormal expression of BAMBI at the mRNA and protein levels contributes to various human pathologies, including obesity and cancer. In the present review, the structure of BAMBI is briefly introduced and its associated signaling pathways and physiological functions are described. Understanding of BAMBI structure and function may contribute to knowledge regarding the occurrence of diseases, including obesity and diabetes, among others. The present review provides a theoretical foundation for the development of BAMBI as a potential biomarker or therapeutic target.

Parkinson's disease (PD) is a common neurodegenerative pathology whose major clinical symptoms are movement disorders. The main pathological characteristics of PD are the selective death of dopaminergic (DA) neurons in the pars compacta of the substantia nigra and the presence of Lewy bodies containing α-synuclein (α-Syn) within these neurons. PD is associated with numerous risk factors, including environmental factors, genetic mutations and aging. In many cases, the complex interplay of numerous risk factors leads to the onset of PD. The mutated α-Syn gene, which expresses pathologicalα-Syn protein, can cause PD. Another important feature of PD is neuroinflammation, which is conducive to neuronal death. α-Syn is able to interact with certain cell types in the brain, including through phagocytosis and degradation of α-Syn by glial cells, activation of inflammatory pathways by α-Syn in glial cells, transmission of α-Syn between glial cells and neurons, and interactions between peripheral immune cells and α-Syn. In addition to the aforementioned risk factors, PD may also be associated with aging, as the prevalence of PD increases with advancing age. The aging process impairs the cellular clearance mechanism, which leads to chronic inflammation and the accumulation of intracellular α-Syn, which results in DA neuronal death. In the present review, the age-associated α-Syn pathogenicity and the interactions between α-Syn and certain types of cells within the brain are discussed to facilitate understanding of the mechanisms of PD pathogenesis, which may potentially provide insight for the future clinical treatment of PD.
帕金森病(PD)是一种常见的神经退行性病变,其主要临床症状是运动障碍。帕金森病的主要病理特征是黑质紧实旁的多巴胺能(DA)神经元选择性死亡,以及这些神经元内出现含有α-突触核蛋白(α-Syn)的路易体。帕金森病与多种风险因素有关,包括环境因素、基因突变和衰老。在许多病例中,众多风险因素的复杂相互作用导致了帕金森病的发病。α-Syn基因突变会表达病理性α-Syn蛋白,从而导致帕金森病。α-Syn能够与大脑中的某些细胞类型相互作用,包括通过神经胶质细胞吞噬和降解α-Syn、神经胶质细胞中的α-Syn激活炎症通路、神经胶质细胞和神经元之间的α-Syn传递以及外周免疫细胞和α-Syn之间的相互作用。除了上述风险因素外,帕金森氏症还可能与衰老有关,因为帕金森氏症的发病率会随着年龄的增长而增加。衰老过程会损害细胞清除机制,导致慢性炎症和细胞内α-Syn的积累,从而导致DA神经元死亡。本综述讨论了与年龄相关的α-Syn致病性以及α-Syn与脑内某些类型细胞之间的相互作用,以促进对帕金森病发病机制的理解,从而为未来临床治疗帕金森病提供启示。

Chronic liver disease can cause an increase in portal sinus pressure, which may lead to rupture and bleeding of esophageal and gastric varices. Oesophageal variceal ligation, with use of sclerosing agent and tissue glue injection is commonly used in clinical practice to address oesophageal bleeding. A 58-year-old male patient with chronic liver disease was treated with oesophageal variceal ligation, sclerosing agent and tissue glue injection due to oesophageal and gastric variceal bleeding. After 2 days, the skin of the patient exhibited erythema to different degrees. After 10 days of dexamethasone treatment, the whole-body rash worsened, and a severe skin reaction appeared that was suggestive of toxic epidermal necrolysis (TEN). Strict mucosal care was provided, and corticosteroids, γ globulin and adalimumab were concurrently used for treatment. After 20 days, the patient recovered from the skin problems. To the best of our knowledge, TEN after endoscopic surgery has rarely been reported in the relevant literature. Furthermore, when patients being treated with multiple drugs have erythema multiforme, physicians should be alert to the possibility of its development into TEN. The present case report summarizes the treatment methods for patients with TEN, providing a practical clinical basis and direction for the future diagnosis and treatment of the condition.
慢性肝病会导致门静脉窦压力升高,从而可能导致食管和胃静脉曲张破裂和出血。临床上常用食管静脉曲张结扎术,配合使用硬化剂和组织胶注射来解决食管出血问题。一名 58 岁的男性慢性肝病患者因食道和胃静脉曲张出血,接受了食道静脉曲张结扎、硬化剂和组织胶注射治疗。2 天后,患者皮肤出现不同程度的红斑。地塞米松治疗 10 天后,全身皮疹加重,出现严重的皮肤反应,提示为中毒性表皮坏死(TEN)。患者接受了严格的粘膜护理,并同时使用皮质类固醇、γ 球蛋白和阿达木单抗进行治疗。20 天后,患者的皮肤问题痊愈。据我们所知,内窥镜手术后出现 TEN 的情况在相关文献中鲜有报道。此外,当接受多种药物治疗的患者出现多形红斑时,医生应警惕其发展为 TEN 的可能性。本病例报告总结了 TEN 患者的治疗方法,为今后的诊断和治疗提供了实用的临床依据和方向。

Coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and a high mortality rate, particularly among elderly patients. Since the beginning of the pandemic, an older age has been recognized as a critical risk factor for disease severity, with increasing mortality rates in each decade of life. This phenomenon may be a consequence of a poor previous health status, with a higher prevalence of pre-existing comorbidities and a higher degree of frailty. The majority of studies on the outcomes and risk factors of elderly patients refer to the first waves of the pandemic and the predictors of in-hospital mortality in these patients. The aim of the present study was to provide a detailed description of the clinical characteristics and management of a cohort of elderly patients (≥65 years of age) who were hospitalized with COVID-19-related pneumonia in all phases of the pandemic, presenting their outcomes, and investigating predictors of in-hospital and out-of-hospital mortality over a period of 1 year in this particularly vulnerable population. A total of 1,124 elderly patients (603 males, 53.7%) with a mean age of 78.51±7.42 years and a median Charlson comorbidity index (CCI) of 5 were included in the study. Of these patients, 104 (9.3%) were hospitalized during the period of prevalence of the original strain Wuhan, 385 (34.3%) were hospitalized during the period of prevalence of the Alpha variant, 221 (19.7%) were hospitalized during the period of prevalence of the Delta variant, and 414 (36.8%) were hospitalized during the period of prevalence of the Omicron variant. Overall, the in-hospital mortality rate was 33.4% (375 patients), and the 1-year mortality rate was 44.7% (502 patients). The majority of patients had not been vaccinated or had not completed full vaccination against severe acute respiratory syndrome coronavirus-2 (843 patients, 75%), given the period of infection. Age, immature granulocytes, lactate dehydrogenase (LDH) levels, ferritin levels, chest X-ray score, as well as the absence of full vaccination, cough and fatigue, were statistically significantly and independently associated with in-hospital mortality, while age, LDH levels, ferritin levels, alanine aminotransferase levels, CCI, chest X-ray score, the absence of cough and fatigue, and a history of dementia were statistically significantly and independently associated with 1-year mortality. On the whole, the present study demonstrates that both the in-hospital mortality and 1-year mortality rates of elderly patients hospitalized due to COVID-19-related pneumonia are high.
冠状病毒病 2019(COVID-19)的特点是疗效差、死亡率高,尤其是老年患者。自这一流行病开始流行以来,人们就认识到,年龄越大是疾病严重程度的关键风险因素,每十年的死亡率都在增加。这种现象可能是以往健康状况较差、原有合并症较多、体弱程度较高的结果。关于老年患者的预后和风险因素的大多数研究都是针对第一波大流行以及这些患者院内死亡率的预测因素。本研究旨在详细描述大流行各阶段因 COVID-19 相关肺炎住院的老年患者(年龄≥65 岁)的临床特征和管理情况,介绍他们的治疗结果,并对这一特别易感人群一年内的院内和院外死亡率预测因素进行调查。研究共纳入了 1124 名老年患者(603 名男性,占 53.7%),他们的平均年龄为 78.51±7.42 岁,夏尔森综合症指数(CCI)中位数为 5。在这些患者中,104 人(9.3%)在武汉原株流行期间住院,385 人(34.3%)在阿尔法变异株流行期间住院,221 人(19.7%)在德尔塔变异株流行期间住院,414 人(36.8%)在奥米克隆变异株流行期间住院。总体而言,院内死亡率为 33.4%(375 名患者),1 年死亡率为 44.7%(502 名患者)。考虑到感染时间,大多数患者未接种或未完成严重急性呼吸系统综合征冠状病毒-2的全面接种(843名患者,75%)。年龄、未成熟粒细胞、乳酸脱氢酶(LDH)水平、铁蛋白水平、胸部 X 光片评分以及未接种全部疫苗、咳嗽和疲劳与院内死亡率在统计学上有显著的独立相关性,而年龄、LDH 水平、铁蛋白水平、丙氨酸氨基转移酶水平、CCI、胸部 X 光片评分、未咳嗽和疲劳以及痴呆病史与 1 年死亡率在统计学上有显著的独立相关性。总体而言,本研究表明,因 COVID-19 相关肺炎住院的老年患者的院内死亡率和 1 年死亡率都很高。

Paraganglioma (PGL) usually presents as the elevation of blood pressure and metabolic changes in patients, and its common symptoms are persistent or paroxysmal hypertension. However, some patients have no typical clinical symptoms, such as patients with non-functional PGL. Therefore, the present study reviewed the literature and summarized the present rare case to provide more accurate and in-depth help for clinical diagnosis and comprehensive treatment. The case was a 64-year-old female with epigastrium malaise for 1 year and aggravation for 7 days. Contrast-enhanced CT revealed that the soft tissue of the irregular mass was in the front of the kidney on the right abdomen with a clear boundary and the size was ~6.5x5.4x6.6 cm. Large vessels were observed in the interior and edge of the lesion. The present study prepared for retroperitoneal tumour resection according to the diagnosis of PGL. After the operation, the patient recovered smoothly and was discharged from the hospital. As of March 2023, the general condition of the patient is good.
副神经节瘤(PGL)通常表现为患者血压升高和新陈代谢改变,常见症状为持续性或阵发性高血压。然而,有些患者没有典型的临床症状,如非功能性副神经纤维瘤患者。因此,本研究对文献进行了梳理,并对本罕见病例进行了总结,以期为临床诊断和综合治疗提供更准确、更深入的帮助。病例为一名 64 岁女性,上腹不适 1 年,加重 7 天。对比增强 CT 显示,不规则肿块软组织位于右腹肾脏前方,边界清晰,大小约为 6.5x5.4x6.6 厘米。病灶内部和边缘可见大血管。本研究根据 PGL 的诊断结果,准备进行腹膜后肿瘤切除术。术后,患者顺利康复出院。截至 2023 年 3 月,患者一般状况良好。

The ovary is an essential reproductive organ in the female organism and its development seriously affects the physical and mental health of female patients. Ovarian diseases include ovarian cancer, premature ovarian insufficiency (POI) and polycystic ovary syndrome (PCOS). Women should pay attention to the most effective treatments for this condition because it is one of the most prevalent gynecological illnesses at present. Extracellular vesicles (EVs), which are smaller vesicles that mediate the exchange of cellular information, include the three categories of exosomes, microvesicles and apoptotic bodies. They are able to transport proteins, RNA and other substances to adjacent or distal cells, thus allowing cellular and tissue homeostasis to be maintained. Numerous previous studies have revealed that EVs are crucial for the treatment of ovarian diseases. They are known to transport its contents to ovarian cancer cells as well as other ovarian cells such as granulosa cells, affecting the development of ovarian disease processes. Therefore, this extracellular vesicle may be involved as a target in the therapeutic process of ovarian disease and may have great potential in the treatment of ovarian disease. In the present review, the role of EVs in the development of three ovarian diseases, including ovarian cancer, POI and PCOS, was mainly summarizes. It is expected that this will provide some theoretical support for the treatment of ovarian disease.
卵巢是女性机体中重要的生殖器官,它的发育严重影响着女性患者的身心健康。卵巢疾病包括卵巢癌、卵巢早衰(POI)和多囊卵巢综合征(PCOS)。由于卵巢疾病是目前最常见的妇科疾病之一,因此女性应关注最有效的治疗方法。细胞外囊泡(EVs)是介导细胞信息交换的较小囊泡,包括外泌体、微囊泡和凋亡体三大类。它们能够将蛋白质、核糖核酸和其他物质运送到邻近或远端细胞,从而维持细胞和组织的平衡。以往的大量研究表明,EVs 对卵巢疾病的治疗至关重要。众所周知,它们能将其内容物运送到卵巢癌细胞以及颗粒细胞等其他卵巢细胞,影响卵巢疾病的发展过程。因此,这种细胞外囊泡可能是卵巢疾病治疗过程中的一个靶点,在治疗卵巢疾病方面具有巨大潜力。本综述主要总结了 EVs 在三种卵巢疾病(包括卵巢癌、卵巢炎和多囊卵巢综合征)发病过程中的作用。希望能为卵巢疾病的治疗提供一些理论支持。
