Liver fibrosis is a key process in the progression of chronic liver diseases. However, there are currently no drugs specifically designed to treat liver fibrosis. Our Phase 2 trial of hydronidone for the treatment of chronic hepatitis B (CHB)-associated liver fibrosis showed that adding hydronidone to entecavir resulted in significant reversal of liver fibrosis. To further evaluate the efficacy of a 270 mg/day dose of hydronidone for treating liver fibrosis associated with CHB, we conducted this Phase 3 trial.

This is a 52-week, randomized (1:1), double-blind, placebo-controlled, multicenter, entecavir-based Phase 3 clinical study conducted at 44 study centers across China. Adult patients aged 18 to 65 years with significant liver fibrosis (defined as an Ishak score ≥ 3 on liver biopsy) associated with CHB were included.

The primary endpoint of the trial is to demonstrate the efficacy of fibrosis reversal, defined as a decrease in the Ishak stage score of liver fibrosis by ≥1 after 52 weeks of treatment, compared to baseline.

The results of this trial are expected to further support the antifibrotic indication for this novel drug.

Ferroptosis plays an essential role in chronic liver diseases, and cyclooxygenase-2 (COX-2) affects liver fibrosis through multiple mechanisms. However, research on COX-2 regulation of ferroptosis in chronic liver injury remains limited. This study aimed to investigate whether and how COX-2 regulates ferroptosis in chronic liver injury.

In vivo, a thioacetamide (TAA)-induced chronic liver injury model, characterized by significant liver lipid peroxidation and oxidative stress, was used. COX-2+/+ and COX-2–/– mice were treated with TAA or normal saline. In vitro, primary mouse hepatocytes were isolated and treated with dimethyl sulfoxide (DMSO), erastin+DMSO, etoricoxib+erastin+DMSO, and tBHQ+erastin+DMSO. Mitochondrial morphology, iron metabolism, lipid peroxidation, and oxidative stress were assessed to verify ferroptosis. The nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway was measured to investigate the relationship between COX-2 and ferroptosis.

TAA-treated COX-2–/– mice presented milder liver fibrosis, whereas TAA-treated COX-2–/– mice livers and etoricoxib+erastin+DMSO-treated primary hepatocytes exhibited alleviated mitochondrial damage compared with TAA-treated COX-2+/+ littermates and erastin+DMSO-treated primary hepatocytes, respectively. The knockout of COX-2 decreased ferrous ion concentration (p < 0.01) and mitigated lipid peroxidation in TAA-treated livers (p < 0.05). Furthermore, both COX-2 knockout and etoricoxib restored reduced glutathione (p < 0.05) and glutathione peroxidase 4 (p < 0.05), while decreasing malondialdehyde levels (p < 0.05). Additionally, COX-2 inhibition upregulated Nrf2, which helped alleviate erastin+DMSO-induced ferroptosis (p < 0.01).

Ferroptosis contributes to the progression of chronic liver injury. Inhibition of COX-2 upregulates Nrf2, mitigating hepatocyte ferroptosis in chronic liver injury.

Balamuthia mandrillaris is a free-living amoeba that can cause granulomatous amoebic encephalitis, a lethal neurological condition in humans. This pathogen infects not only immunocompromised hosts but, more commonly, immunocompetent individuals. Balamuthia mandrillaris mainly infects the skin and nervous system. When it affects the nervous system, it can manifest as Balamuthia mandrillaris encephalitis (BAE). This article presents a case of BAE in central China, diagnosed through next-generation sequencing and histopathology. The patient is a 64-year-old male who was admitted to the Department of Neurosurgery with a one-week history of headache. Magnetic resonance imaging scans revealed a mass in the right temporal-occipital region, and postoperative pathological examination confirmed that the lesion was BAE. We will detail the clinical course of this disease in this patient, aiming to enhance clinicians’ understanding of Balamuthia mandrillaris infections.

Patients with cirrhosis are at an increased risk of bacterial infection (BI), which is the most common precondition for acute-on-chronic liver failure (ACLF). In this study, we aimed to evaluate the ability of mitochondria-related indicators (mitochondrial mass and mitochondrial membrane potential (MMP)) of T cells in peripheral blood to predict BI and ACLF within 90 days in cirrhotic patients.

We prospectively studied mitochondria-related indicators in various T cells from 235 cirrhotic patients at the Second Hospital of Nanjing. The outcomes of interest were BI and ACLF.

The restricted cubic spline analysis showed that the MMP of CD8+ T cells had a linear relationship with the risk of BI and ACLF (both P < 0.001). Multivariable Cox regression analysis demonstrated that the MMP of CD8+ T cells was an independent risk factor for both BI and ACLF (BI: hazard ratio 0.96, 95% confidence interval 0.94–0.98; P < 0.001; ACLF: hazard ratio 0.94, 95% confidence interval 0.90–0.97; P < 0.001). The MMP of CD8+ T cells exhibited better diagnostic efficacy than traditional indices in predicting BI (C index: 0.75). The MMP of CD8+ T cells, when combined with traditional models (Child-Turcotte-Pugh and model for end-stage liver disease score), improved their diagnostic efficiency in predicting both BI and ACLF. Additionally, the MMP of CD8+ T cells showed a significant negative correlation with inflammation-related markers (P < 0.05). Mitochondrial damage and abnormally activated mitochondrial autophagy were observed in CD8+ T cells from cirrhotic patients with low MMP.

The MMP of CD8+ T cells could serve as a valuable predictor of BI and ACLF within 90 days in cirrhotic patients.

Gastrointestinal complications are common in patients after ischemic stroke. Gastric motility is regulated by gastric pace-making activity (also called gastric myoelectrical activity (GMA)) and autonomic function. The aim of this study was to evaluate GMA, assessed by noninvasive electrogastrography (EGG), and autonomic function, measured via spectral analysis of heart rate variability derived from the electrocardiogram in patients with ischemic stroke.

EGG and electrocardiogram were simultaneously recorded in both fasting and postprandial states in 14 patients with ischemic stroke and 11 healthy controls. Multi-channel surface EGG was used to measure GMA, and autonomic function was evaluated by heart rate variability spectral analysis.

Compared to healthy subjects, patients with ischemic stroke, especially those with a modified Rankin scale ≥ 4, had impaired GMA in both fasting and postprandial states. This included a lower percentage of normal gastric slow waves (the basic rhythmic waves of GMA) and a higher percentage of tachygastria, bradygastria, or arrhythmia. Patients with ischemic stroke also showed a decrease in the dominant frequency and power of the gastric slow waves. Autonomic functions were altered in ischemic stroke patients with a modified Rankin scale ≥ 4, as reflected by increased sympathetic activity and reduced parasympathetic activity.

Gastric pace-making activity is impaired in patients with severe ischemic stroke, as evidenced by a reduced percentage of normal gastric slow waves and a lower frequency of gastric slow waves, likely due to impaired autonomic functions.

Large-scale data on the hepatitis D virus (HDV)/hepatitis B virus (HBV) co-infection rate is needed to estimate the current epidemiology of HDV in China. This study aimed to estimate the current epidemiology of HDV.

Patients with chronic HBV infection, with documented serum hepatitis B surface antigen (HBsAg) positivity for more than six months, were enrolled across China. Blood samples were collected at baseline for central evaluations of HDV antibody and HBsAg quantification. Assessments for antibodies of hepatitis A virus, hepatitis C virus, hepatitis E virus, and human immunodeficiency virus, as well as HDV RNA quantification, were performed in patients who tested positive for HDV antibodies.

Of the 5,044 enrolled patients between September 24, 2021, and December 28, 2022, 4,936 patients were included in the analysis. The mean age (±standard deviation) was 42.9 ± 9.9 years, and 69.8% of patients were male. The mean alanine aminotransferase level was 34 ± 58 U/L, and 1,509 (30.6%) patients were hepatitis B e antigen-positive. The mean (standard deviation) HBsAg level at baseline was 3,535 ± 11,292 IU/mL among 4,842 patients who were HBsAg positive. The rate of HBV infection and HDV antibody positivity was 0.24% (95% confidence interval: 0.1–0.4%), and only one patient was HDV RNA positive.

The prevalence of HDV antibody positivity was 0.24% in Chinese patients with chronic HBV infection, and only one patient with both anti-HDV antibody and HDV RNA positivity was observed in this study.

The spatial heterogeneity of tumors has long been a subject of significant interest in oncology. Recent research has revealed that tumors and their microenvironments undergo dynamic changes over time, particularly in the form of periodic circadian rhythms. Disruptions to these rhythms have been recognized as a pivotal factor in the advancement of tumorigenesis. Such disruptions not only induce dysregulation of gene expression within tumor cells, influencing tumor growth, metabolism, the cell cycle, and vascular homeostasis but also facilitate metastasis. Furthermore, they mediate the remodeling of the tumor immune microenvironment, fostering the development of an immunosuppressive milieu. Additionally, the in vivo metabolism and therapeutic responsiveness of tumor treatments—including chemotherapy, targeted therapy, and immunotherapy—have been shown to be modulated by circadian rhythms. This suggests that time-specific drug administration may enhance treatment efficacy, offering novel insights for precision cancer therapy. In this review, we systematically update contemporary research on the impact of circadian rhythms on tumor biology, encompassing both tumor progression and the efficacy of drug therapies. Building upon these insights, we explore the potential for a synergistic approach that integrates the targeting of rhythmic genes with current tumor treatment modalities. We also discuss the feasibility of tailoring tumor therapy to the rhythmic alterations that define in vivo metabolism and the efficacy of specific therapeutic agents, highlighting the significance of rhythm-based strategies in the personalized treatment of tumors and the prevention of associated diseases.

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Multiple treatment modalities are available for the management of HCC, depending on its stage as determined by the Barcelona Clinic Liver Cancer staging system. Because liver transplantation (LT) theoretically removes the cancer and replaces the organ at risk for future malignancy, LT is often considered the most definitive and one of the most efficacious treatment options for HCC. Nevertheless, the success and efficacy of liver transplantation depend on various tumor characteristics. As a result, multiple criteria have been developed to assess the appropriateness of a case of HCC for LT, with the pioneering Milan Criteria established in 1996. Over the past 20 to 30 years, these criteria have been critically evaluated, expanded, and often liberalized to make LT for patients with HCC a more universally applicable option. Furthermore, the development of other treatment modalities has enabled downstaging and bridging strategies for HCC prior to LT. In this narrative and comprehensive review, we provided an update on recent trends in the epidemiology of HCC, selection criteria for LT, implementation of LT across different regions, treatment modalities available as bridges, downstaging strategies, alternatives to LT, and, finally, post-LT surveillance.

The tumor microenvironment (TME) consists of a complex mix of cellular and non-cellular components, including immune cells, stromal cells, extracellular matrix, cytokines, and growth factors. These elements interact with tumor cells to influence tumorigenesis, growth, invasion, and metastasis. Long noncoding RNAs (lncRNAs)—a class of non-coding RNAs longer than 200 nucleotides—have attracted considerable attention for their roles in regulating gene expression at the epigenetic, transcriptional, and post-transcriptional levels. Emerging evidence suggests that lncRNAs are crucial in shaping the TME by modulating processes such as immune evasion, angiogenesis, metabolic reprogramming, and the maintenance of cancer stem cells. This review provides an overview of the current understanding of lncRNAs in the TME, focusing on their involvement in key signaling pathways and cellular interactions that drive tumor progression. We discussed how lncRNAs contribute to extracellular matrix remodeling, facilitate communication between tumor and stromal cells, and regulate immune cell infiltration and function within the TME. Additionally, we explore the potential of lncRNAs as biomarkers for early cancer detection and prognosis, as well as their promise as therapeutic targets to disrupt tumor-microenvironment crosstalk. The review also addresses challenges in targeting lncRNAs therapeutically, such as ensuring specificity, minimizing off-target effects, and achieving effective in vivo delivery of lncRNA-targeted therapies. Strategies to overcome these challenges include the development of highly specific lncRNA knockout technologies and the use of advanced delivery systems, such as nanoparticles and viral vectors, to precisely target tumor-associated cells. Overall, this review underscores the significant role of lncRNAs in the TME and their potential as novel tools for enhancing cancer diagnosis and treatment. By elucidating the multifaceted roles of lncRNAs in the TME, we aimed to provide insights that could lead to more effective, targeted therapeutic strategies, ultimately advancing cancer research and improving patient care.

Recent studies have highlighted a link between amyotrophic lateral sclerosis (ALS) and gut microbiota. This prospective study aimed to evaluate the effects of electroacupuncture combined with Chinese herbal medicine on gut microbiota and metabolomics in ALS patients.

Ten ALS patients were randomly assigned to either a treatment group (electroacupuncture with Chinese herbal medicine, n = 6) or a control group (waiting treatment, n = 4). Healthy controls (age- and sex-matched, n = 10) were also included. Data were collected after 12 sessions of electroacupuncture and follow-ups at three and six months. ALS functional rating scale scores were documented pre- and post-treatment. Stool samples were collected at two time points (T0 and T4 weeks) and analyzed, and metabolomic profiles from urine samples were analyzed post-treatment. Heatmap correlation analysis was used to explore relationships between microbiota, metabolomics, and clinical outcomes.

Treatment with electroacupuncture reduced Eisenbergiella abundance in the treatment group. A significant positive correlation was found between Lachnospiraceae and ALS functional rating scale scores (P < 0.005 and P < 0.001, respectively). Differential expression of purine metabolism was observed in ALS patients (P = 0.0017).

Imbalances in the gut microbiome and metabolic disorders have been found among patients with ALS. These imbalances appear to be partially mitigated by treatment with electroacupuncture combined with Chinese herbal medicine. Our research suggests that Eisenbergiella might be a diagnostic biomarker and a potential therapeutic target for ALS.

Wilson’s disease (WD) is a rare autosomal recessive genetic disorder that can be treated with medications. The lack of a single, specific diagnostic indicator leads to diagnostic difficulties, which may result in disease progression to cirrhosis and even liver cancer. Thus, this study aimed to analyze the clinical data, imaging, histopathological manifestations, genetic testing results, and treatment effects of patients with WD hepatic type, and to explore the factors related to WD cirrhosis.

A single-center retrospective study was performed. 48 WD patients with a Leipzig score ≥ 4 were divided into a cirrhosis group and a non-cirrhosis group based on the presence of cirrhosis. Logistic regression analysis and odds ratios were used to describe the strength of association between risk factors and cirrhosis. The predictive value of the model for cirrhosis occurrence was evaluated by calculating the area under the receiver operating characteristic curve and the cutoff value.

All 48 patients diagnosed with WD had liver damage, with males accounting for 54.17%. The median age at diagnosis was 28 years (range: 10.25–40.5 years), and 39.58% of patients had cirrhosis. The most prevalent mutation was c.2333G>T (p.Arg778Leu), found in 41.30% (19/46) of cases. Imaging revealed fatty liver in 31.25% (15/48) of patients and “honeycomb-like” cirrhosis nodules in 73.68% (14/19). Compared with the non-cirrhosis group, the cirrhosis group had a higher positive rate for the Kayser-Fleischer (K-F) ring, older age at diagnosis, and higher levels of immunoglobulin G, but lower levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, white blood cells, and platelets (p < 0.05). Age at diagnosis (odds ratio = 1.072, 95% confidence interval = 1.007–1.142, p = 0.03) and the K-F ring (odds ratio = 18.657, 95% confidence interval = 1.451–239.924, p = 0.025) were independent risk factors for WD-related cirrhosis. The best values of area under the receiver operating characteristic curve for age at diagnosis combined with the K-F ring in predicting WD cirrhosis were 0.909. The average follow-up time for 33 patients was 48.6 months (range: 12–72 months). The biochemical recovery rate was over 60% after 12–72 months of treatment with zinc gluconate and/or penicillamine.

Age at diagnosis, combined with the K-F ring, is a simple and effective risk factor for WD-related cirrhosis. Zinc gluconate and penicillamine are safe and effective treatments.

Cholesterol synthesis and gallstone formation are promoted by trimethylamine-N-oxide (TMAO), a derivative of trimethylamine, which is a metabolite of gut microbiota. However, the underlying mechanisms of TMAO-induced lithogenesis remain incompletely understood. This study aimed to explore the specific molecular mechanisms through which TMAO promotes gallstone formation.

Enzyme-linked immunosorbent assays were used to compare serum concentrations of TMAO, apolipoprotein A4 (APOA4), and proprotein convertase subtilisin/kexin type 9 (PCSK9) between patients with cholelithiasis and normal controls. A murine model of TMAO-induced cholelithiasis was employed, incorporating assays of gallstone weight and bile cholesterol content, along with RNA sequencing of murine hepatic tissue. A TMAO-induced AML12 hepatocyte line was constructed and transfected with targeted small interfering RNAs and overexpression plasmids. In vivo and in vitro experiments were performed to determine the expression and regulation of genes related to cholesterol metabolism.

Serum TMAO and PCSK9 levels were elevated, whereas APOA4 levels were reduced in patients with cholelithiasis. Furthermore, our murine model demonstrated that TMAO upregulated hepatic expression of PCSK9, 3-hydroxy-3-methylglutaryl-CoA reductase, and ATP-binding cassette sub-family G member 5/8, while reducing APOA4 expression, thereby modulating cholesterol metabolism and promoting lithogenesis. PCSK9 and APOA4 were identified as key regulatory genes in the cholesterol metabolic pathway. PCSK9 knockdown increased APOA4 expression, while APOA4 overexpression led to reduced PCSK9 expression.

TMAO upregulated hepatic PCSK9 expression and reduced APOA4 expression, initiating a feedback loop that dysregulated cholesterol metabolism and promoted lithogenesis.

General transcription factor IIIC subunit 2 (GTF3C2) is one of the polymerase III transcription-related factors. Previous studies have revealed that GTF3C2 is involved in regulating cell proliferation. However, the role of GTF3C2 in hepatocellular carcinoma (HCC) remains unclear. This study aimed to determine its expression, biological function, and mechanism in HCC.

The expression of GTF3C2 in HCC and non-tumor tissues, along with its clinical significance, was investigated using public databases and clinical samples. Reverse transcription-quantitative polymerase chain reaction and Western blot assays were performed to detect the expression of GTF3C2, ubiquitin specific peptidase 21 (USP21), mitogen-activated protein kinase 2 (MEK2), extracellular signal-regulated kinase 1/2 (ERK1/2), and p-ERK1/2 in cells. A luciferase reporter assay was conducted to explore the regulatory effect of GTF3C2 on USP21 transcription. Cell Counting Kit-8, 5-ethynyl-2′-deoxyuridine, and colony formation assays were performed to assess HCC cell proliferation. Subcutaneous injection of HCC cells into nude mice was used to evaluate tumor growth in vivo.

GTF3C2 expression was upregulated in HCC tissues and was positively correlated with advanced tumor stages and high tumor grades. HCC patients with high GTF3C2 expression had significantly worse survival outcomes. Knockdown of GTF3C2 suppressed the proliferation of Hep3B and HCCLM3 cells, while overexpression of GTF3C2 facilitated the proliferation of SNU449 and Huh7 cells. GTF3C2 promoted USP21 expression by activating its transcription, which subsequently increased the levels of MEK2 and p-ERK1/2 in HCC cells. Overexpression of both USP21 and MEK2 counteracted the GTF3C2 knockdown-induced inactivation of the ERK1/2 pathway. Moreover, GTF3C2 promoted HCC cell proliferation in vitro and tumor growth in vivo by regulating the USP21/MEK2/ERK1/2 pathway.

Upregulation of GTF3C2 is frequently observed in HCC tissues and predicts poor prognosis. GTF3C2 promotes HCC cell proliferation via the USP21/MEK2/ERK1/2 pathway.

Direct-acting antivirals (DAAs) have dramatically changed the landscape of chronic hepatitis C virus (HCV) treatment and significantly reduced the risk of HCV-related hepatocellular carcinoma (HCC) after achieving sustained virologic response. However, the risk of HCC persists, particularly in patients with pre-treatment cirrhosis or fibrosis stage 3 (F3), even after DAA-induced viral eradication. While professional guidelines agree on the need for surveillance in cirrhotic patients, there is no consensus regarding surveillance for the pre-treatment F3 population following HCV eradication. The risk of HCC in the F3 population falls below the threshold for cost-effective surveillance. However, co-existing risk factors—such as diabetes, hepatic steatosis, alcohol use, advanced age, and elevated alpha-fetoprotein levels—may warrant reconsideration of HCC surveillance in this group. This underscores the need for an individualized, risk-based approach to HCC surveillance. This review provided a simplified algorithm to assist clinicians in managing patients with HCV after DAA-induced sustained virologic response.

Cancer continues to pose a substantial public health problem in Nigeria, characterized by rising rates of occurrence and mortality. While there is increasing interest in using natural products for cancer treatment, comprehensive data on the specific bioactive compounds in these plants and how they modulate different types of cancer are still lacking. Additionally, although traditional knowledge about these food plants is rich and valuable, it has not been fully integrated with modern scientific research to create standardized treatment protocols. Scientific databases like PubMed, ScienceDirect, Google Scholar, and ResearchGate were explored to retrieve empirical data. The key plants discussed are Spondias mombin, Xanthosoma sagittifolium, Elaeis guineensis, Irvingia gabonensis, Allium cepa, Blighia sapida, Dioscorea dumetorum, Psidium guajava, and Talinum triangulare. These plants demonstrate a wide range of anticancer properties, including the ability to induce apoptosis (cell death), halt the cell cycle, inhibit angiogenesis, and regulate inflammatory responses. They contain a variety of phytochemicals, such as flavonoids, tannins, terpenoids, alkaloids, and organosulfur compounds, which contribute to their anticancer effects. For example, Spondias mombin contains flavonoids that inhibit the formation of tumors, whereas Xanthosoma sagittifolium exhibits cytotoxic effects against leukemia cells. Additionally, Elaeis guineensis exhibits antioxidant properties that counteract oxidative stress, a crucial factor in cancer progression. This review highlights the significance of these plants in developing complementary cancer therapies that can be used alongside conventional treatments. By combining traditional knowledge with contemporary scientific methods, these medicinal plants have the potential to provide innovative approaches to cancer prevention and treatment, addressing the pressing demand for safer and more efficient therapeutic alternatives.
