Fuzi, the processed product of daughter roots of Aconitum carmichaelii Debx., is a well-known Chinese medicine for the treatment of heart failure (HF) and related cardiac diseases. This study aimed to investigate the molecular mechanism of the cardioprotective effects of Fuzi water decoction (FWD) and Fuzi water-soluble alkaloids (FWA) on the model of HF.

The HF model of rats was prepared through intravenous injection of propafenone hydrochloride. The normal group, model group, FWD-treated groups (1.25 g/kg, 2.5 g/kg, 5 g/kg) and positive group (Shenfu Injection, 3.3 mL/kg) were set up. Heart rate, LV+dp/dtmax, and LV-dp/dtmax were recorded at 5 m, 10 m, 20 m, 30 m, and 60 m after drug administration, respectively. The contents of atrial natriuretic peptide, brain natriuretic peptide (BNP), angiotensin II, and aldosterone in serum were determined 20 m post-administration. An in vitro cardiomyocyte hypertrophy model with HDAC2 overexpression was constructed and verified by lentivirus transfection. The experiment included a blank group, FWD-treated groups (3 mg/mL, 1.5 mg/mL), and FWA-treated groups (4 mg/mL, 2 mg/mL). For transcriptome analysis, the model group, blank group, and FWD-treated group (2.5 g/kg) at 20 m and 60 m in vivo, and different dose groups in vitro, were selected to analyze the therapeutic mechanisms of FWD and FWA.

All FWD treatment groups showed an increased heart rate, among which the groups with 2.5 g/kg and 5 g/kg FWD showed better effects, significantly increasing LV+dp/dtmax and LV-dp/dtmax after 20 m of administration and significantly reducing BNP and aldosterone serum levels. In the constructed cardiomyocyte hypertrophy model, HDAC2 expression, atrial natriuretic peptide and BNP protein levels, and cell surface area increased. Transcriptome data from both in vivo and in vitro showed that FWD and FWA could exert cardioprotective effects through pathways such as the PI3K-Akt signaling pathway, NF-κB signaling pathway, and ATP-binding cassette (ABC) transporters, involving key genes such as ITGB1, TLR2, and CDKN1A. Fuzi inhibited the hypertrophic gene HDAC2. Additionally, based on weighted gene co-expression network analysis, ABC transporters may be an important molecular pathway for FWA in treating HF.

Both FWD and FWA can ameliorate HF by regulating apoptosis, proliferation, and anti-fibrosis, with ABC transporters potentially being the main pathway for the action of FWA.

Gut dysbiosis and abnormal cytokine profiles are common in cirrhosis. This study aimed to evaluate the correlations between them.

In the blood plasma of cirrhosis patients and controls, 27 cytokines were examined using a multiplex assay. The plasma levels of nitrites (stable metabolites of the endothelial dysfunction biomarker nitric oxide) and lipopolysaccharide (LPS) were examined. The fecal microbiota was assessed by 16S rRNA gene sequencing.

Levels of IL-1b, IL-2, IL-6, IL-13, IP-10, IFN-g, TNF-a, LPS, and nitrites were higher in cirrhosis patients than in controls, while levels of IL-4, IL-7, and PDGF-BB were lower. The LPS level was directly correlated with the levels of IL-1b, IL1-Ra, IL-9, IL-17, PDGF-BB, IL-6, TNF-a, and nitrites. The nitrite level was significantly directly correlated with the levels of TNF-a, GM-CSF, IL-17, and IL-12, and inversely correlated with the IL-7 level. TNF-a levels were directly correlated with ascites severity and the abundance of Negativicutes, Enterobacteriaceae, Veillonellaceae, and Klebsiella, while inversely correlated with the abundance of Firmicutes, Clostridia, and Subdoligranulum. IFN-g levels were directly correlated with the abundance of Bacteroidaceae, Lactobacillaceae, Bacteroides, and Megasphaera, and inversely correlated with the abundance of Verrucomicrobiota, Akkermansiaceae, Coriobacteriaceae, Akkermansia, Collinsella, and Gemella. IL-1b levels were directly correlated with the abundance of Comamonadaceae and Enterobacteriaceae and inversely correlated with the abundance of Marinifilaceae and Dialister. IL-6 levels were directly correlated with the abundance of Enterobacteriaceae, hepatic encephalopathy, and ascites severity, and inversely correlated with the abundance of Peptostreptococcaceae, Streptococcaceae, and Streptococcus.

The abundance of harmful gut microbiota taxa and endotoxinemia directly correlates with the levels of proinflammatory cytokines.

The brain-gut axis represents a bidirectional communication network that integrates neural, hormonal, and immunological signaling between the central nervous system and the gastrointestinal tract. Adverse childhood experiences (ACEs) have increasingly been recognized for their profound impact on this axis, with implications for both mental and physical health outcomes. This mini-review explores the emerging field of epigenomics—specifically, how epigenetic modifications incurred by ACEs can influence the brain-gut axis and contribute to the pathophysiology of various disorders. We examine the evidence linking epigenetic mechanisms such as DNA methylation, histone modifications, and non-coding RNAs to the modulation of gene expression involved in stress responses, neurodevelopment, and immune function—all of which intersect at the brain-gut axis. Additionally, we discuss the emerging potential of the gut microbiome as both a target and mediator of epigenetic changes, further influencing brain-gut communication in the context of ACEs. The methodological and therapeutic challenges posed by these insights are significant. The reversibility of epigenetic marks and the long-term consequences of early life stress require innovative and comprehensive approaches to intervention. This underscores the need for comprehensive strategies encompassing psychosocial, pharmacological, neuromodulation, and lifestyle interventions tailored to address ACEs’ individualized and persistent effects. Future directions call for a multi-disciplinary approach and longitudinal studies to uncover the full extent of ACEs’ impact on epigenetic regulation and the brain-gut axis, with the goal of developing targeted therapies to mitigate the long-lasting effects on health.

Inflammatory Bowel Diseases (IBD) still represent a significant medical challenge. The course of IBD is characterized by the development of fibrotic, inflammatory, or dysplastic lesions over time. Recent advancements in operative endoscopy have introduced new strategies to address these issues. Inflammatory and fibrotic strictures pose a challenge for clinicians and represent a surgical risk. Endoscopic treatments include dilation, stent placement, and electroincisional techniques. Moreover, endoscopic approaches can also be considered in the management of IBD-related surgical complications. Addressing colorectal dysplastic lesions is a crucial concern, and several resection endoscopic techniques are available, including endoscopic mucosal resection and endoscopic submucosal dissection. This review aimed to summarize the pros and cons of advanced therapeutic endoscopic approaches in the management of IBD.

Several studies have suggested that rose hip extracts have anti-obesity potential. Conventional medicines treating obesity are followed by multiple adverse side effects and is very cost full to society. This makes the investigation of herbal remedies with anti-obesity effects potential highly relevant. This systematic review aims to shed light on the results of existing literature reports on the correlation between the intake of rose hip extracts and anti-obesity effects.

A systematic literature search of PubMed and Web of Science was made to localize relevant experimental literature. Nine articles met the inclusion criteria, including one in vitro study, seven in vivo animal studies, and one human trial with pre-obese subjects. All nine articles are objectively reviewed in this systematic review.

Eight out of nine articles, including the article on humans, presented significant anti-obesity effects. Though some limitations of the studies were found, including the human trial, seven possible metabolic mechanisms are suggested as the underlying cause of the significant effects.

Based on the findings of this review, rose hip extracts containing tiliroside found in the seeds have the potential to become a new herbal remedy with anti-obesity effects. Nevertheless, more research is needed to assess the effectiveness and optimal dosage of the rose hip treatment and to elucidate the underlying mechanisms of the effects.

The hepatitis E virus (HEV) is a zoonotic disease, and infection with HEV in humans primarily causes acute infections and can progress to chronic manifestation in immunocompromised individuals. Over the past decade, guidelines for diagnosing and treating HEV infection have been developed. This study aimed to systematically assess the quality of current guidelines for diagnosing and treating HEV infection, and we analyzed the differences in guideline quality and primary recommendations and explored possible reasons for these differences.

Guidelines published between 2013 and 2022 were searched, and studies were identified using selection criteria. The study assessed the quality of the included guidelines using the Appraisal of Guidelines for Research and Evaluation tool, extracted the primary recommendations in the guidelines, determined the highest level of evidence supporting the recommendations, and reclassified the evidence using the Oxford Centre for Evidence-Based Medicine grading system.

Seven guidelines were included in the final analysis. The quality of the guidelines varied widely. The discrepancies may have been caused by the lack of external experts, the failure to consider influencing factors in guideline application, and the lack of consideration of the public’s opinion. Analysis of the heterogeneity in primary recommendations revealed differences in algorithms for managing chronic HEV infection, the dosage of ribavirin, and a low level of evidence supporting the primary recommendations.

Guideline quality and primary recommendations vary considerably. Refinement by guideline developers and researchers would facilitate updating and applying guidelines for diagnosing and treating HEV infection.

The incidence and prevalence of inflammatory bowel diseases (IBD), including ulcerative colitis and Crohn’s disease, are rapidly increasing. Currently, colonoscopy is the gold standard for diagnosing and monitoring the course of IBD. However, the recently implemented “treat-to-target” strategy, which involves meticulously pursuing multiple therapeutic objectives, has opened avenues for non-invasive diagnostic and monitoring tools. These tools aim to assess disease activity and predict the likelihood of recurrence. Research studies into serum and fecal biomarkers in IBD have been ongoing for several years. Among the most relevant biomarkers, fecal calprotectin and C-reactive protein have shown the best accuracy, with good-to-optimal correlation with endoscopic, histologic, or transmural activity. Numerous studies have explored the potential advantages of using multi-target tools that combine serum and fecal biomarkers with clinical activity indexes to enhance diagnostic and monitoring effectiveness. Encouraging findings have emerged for fecal lactoferrin, autoantibodies, micro-RNA, gene expression, and many other serological and fecal markers. However, limited evidence has hindered their widespread adoption in routine clinical practice. This review aimed to summarize the available data on the utilization of biomarkers in IBD.

Gluten has multiple harmful effects that compromise human health, not only in gluten-dependent diseases but also in non-gluten-affected chronic inflammatory conditions. After consumption, the indigestible gluten peptides are modified by luminal microbial transglutaminase or transported through the gut epithelium to interact with the highly populated mucosal immune cells. As a disruptor of gut permeability, gluten peptides compromise tight junction integrity, allowing foreign immunogenic molecules to reach internal compartments. Gliadin peptides are distributed systemically to remote organs, where they encounter endogenous tissue transglutaminase. Following post-translational deamidation or transamidation, the peptides become immunogenic and pro-inflammatory, inducing organ dysfunction and pathology. Cross-reactivity and sequence homology between gluten/gliadin peptides and human epitopes may contribute to molecular mimicry in autoimmunity induction. A gluten-free diet can prevent these phenomena through various mechanisms. As proof of concept, gluten withdrawal alleviates disease activity in chronic inflammatory, metabolic, and autoimmune conditions, and even in neurodegeneration. We recommend combining the gluten-free and Mediterranean diets to leverage the advantages of both. Before recommending gluten withdrawal for non-gluten-dependent conditions, patients should be asked about gut symptomatology and screened for celiac-associated antibodies. The current list of gluten-induced diseases includes celiac disease, dermatitis herpetiformis, gluten ataxia, gluten allergy, and non-celiac gluten sensitivity. In view of gluten being a universal pro-inflammatory molecule, other non-celiac autoinflammatory and neurodegenerative conditions should be investigated for potential gluten avoidance.

Functional Gastrointestinal Disorders (FGIDs), also recently referred to as disorders of gut-brain interaction, are common in the pediatric population and vary according to age groups, i.e., neonatal/toddler and child/adolescent FGIDs. Pediatric FGIDs tend to evolve and persist into adulthood, contributing to financial burdens and psychological problems. Despite several decades of progress and advancements in molecular biology and medical sciences, the exact pathophysiology remains unknown, although genetic, psychosocial, gut dysbiosis, visceral hypersensitivity, and neuroimmune causes have been implicated. The ROME IV criteria facilitate easier and earlier diagnosis of FGIDs, excluding organic causes while minimizing unnecessary investigations. Dietary, psychosocial, neuro-stimulatory, and pharmacological management methods exist, although fewer trials have focused on pediatric drug-based management. Early identification and appropriate treatment hold the potential for cure and improvement in quality of life.

Precision medicine involves tailoring an individual’s genes or proteins to prevent, diagnose, or treat diseases such as cancer. Given the recent advances in cancer immunotherapy, there is now a focus on developing vaccines as a new treatment modality. Therapeutic vaccines for cancer are a precision medicine approach that has made enormous progress in recent years due to advances in vaccine engineering. This technology uses antigens derived from the patient’s tumor to create vaccines that are unique and specific to that patient. Although challenges remain, significant progress has been made in recent years, largely due to the advent of mRNA vaccines. This mini-review primarily focuses on developments in vaccine engineering, outstanding therapeutic obstacles, and recent human clinical trials.

The tumor microenvironment is a dynamic cellular landscape critical to cancer progression. Within it, tumor-infiltrating lymphocytes hold a dual role, contributing to both tumor suppression and progression. This review synthesized current knowledge on tumor-infiltrating lymphocytes, emphasizing their prognostic significance and therapeutic potential. By dissecting their interactions within the tumor microenvironment and with cancer cells, we sought to uncover the complexities of the immune response in cancer and explored the future direction of immunotherapeutic strategies.

Molecular analysis of breast cancer tissue has revealed that breast cancer is not a uniform disease. Each breast cancer patient has several molecular signatures that differ from those of others. Therefore, breast cancer therapy should be personalized, depending on its molecular signatures. Breast cancer with hormonal receptors can be treated with a selective estrogen receptor modulator or selective estrogen receptor degrader therapy, while breast cancer with overexpression of human epidermal growth factor receptor 2 (HER2)-neu gene responds excellently to anti-HER2-neu therapy. For patients with advanced breast cancer that already has distant metastasis and a poor prognosis, a new agent has been discovered. The phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) inhibitor has been proven effective in treating advanced breast cancer with a PIK3CA gene mutation. This therapy can be administered to HER2-negative breast cancer patients and in combination with selective estrogen receptor degrader therapy for post-menopausal patients with positive hormonal receptors. Although this treatment is effective, it cannot be given to every advanced breast cancer patient. Before administering the treatment, a PIK3CA mutation test is compulsory. PIK3CA mutation detection in breast cancer can predict the cancer’s response to the PIK3CA inhibitor, providing information on which patients will benefit from the treatment.

Esophageal cancer is one of the most common malignant tumors in the digestive tract in China. Due to late diagnosis and rapid progression, it leads to a poor survival prognosis. Early diagnosis and treatment are crucial for improving the prognosis of esophageal cancer. Implementing simple and efficient screening methods is more in line with China’s healthcare economics and national conditions. This article mainly introduces the current status of esophageal cancer screening and new technologies for esophageal cancer screening in China, including endoscopic technology, biomarker detection, exhaled breath detection, and artificial intelligence assisted screening, and looks ahead to its future development trends.

Erdheim-Chester Disease (ECD) is a type of systemic histiocytosis mostly observed in adults, characterized by the infiltration of foamy CD68+ and CD1a- histiocytes into multiple organ systems, often associated with MAPK pathway mutations. Conventional treatment of ECD has been challenging. Currently, targeted drugs (BRAF and MEK inhibitors) are recommended. This report aimed to describe the necessity of targeted therapy for ECD. A 39-year-old Japanese man presented with complaints of weight loss, polyuria/polydipsia, bilateral leg pain, and facial xanthoma/xanthelasma palpebrarum (XP) lesions. A biopsy of the bone lesions confirmed BRAF-positive ECD. The ECD lesions initially showed a good response to the cladribine/dexamethasone regimen; however, XP lesions were exacerbated during infliximab therapy, and did not respond to other conventional regimens. Eventually, XP lesions improved with trametinib (a MEK inhibitor) and dabrafenib (a BRAF inhibitor). Targeted therapy is indispensable in the management of ECD.

Human papillomavirus (HPV)-related oropharyngeal cancers associated with sexual contact are increasing, with high rates in men who have sex with men. HPV-related cancers have the advantage of being frequently detectable through oropharyngeal visual examination and having much higher survival rates than classic oropharyngeal cancers. It has been demonstrated that gay and bisexual men can take smartphone oropharyngeal “selfies” of sufficient quality for screening. However, there is an issue with the inability to move the tongue to allow a clear view of the palatine tonsils, where a majority of oropharyngeal cancer cases occur. We attempted to investigate the feasibility of using commercially available videoscopes to visualize the oropharynx. Fourteen healthy volunteers used a provided low-cost commercial endoscope to video their oropharynx. Participants used the videoscope connected to a laptop and could visualize the oropharynx on the screen. Attempts were observed, and the process was noted. A focus group of participants was carried out immediately afterwards to ascertain barriers and facilitators to using the videoscopes. All participants were able to use the videoscope and obtain videos of sufficient clarity to note major oropharyngeal landmarks. The palatine tonsils were initially difficult to visualize because the tongue could not be sufficiently controlled. Participants were given time to practice using visual cues to control the position of the tongue, which helped in obtaining good videos. Videoscopes can be used effectively with minimal instruction and provide a better view than still images, as they illuminate and magnify the site. Low-cost commercially available videoscopes may be an improvement over smartphone “selfies”.

Oral squamous cell carcinoma (OSCC) is a predominant type of head and neck cancer in the Indian subcontinent, mostly observed among tobacco and/or alcohol users. Oral leukoplakia (OLK) does not seriously affect patients, so it is often ignored in treatment. Some studies have reported genomic alterations and expression deregulation that drive OLK towards OSCC, conducted in two types of studies based on sample collection from (a) disparate or (b) the same patients. Demographic, tobacco/alcohol habits and biological factors may vary significantly if OLK and OSCC samples are collected from disparate patients, but they remain consistent if both tissue samples are from the same patient. Earlier, both targeted candidate gene-based and large-scale omics-based studies identified somatic mutations in TP53, CDKN2A, and PTEN, as well as broad arm-level copy number alterations and epigenetically dysregulated genes in leukoplakia and tumor tissues from disparate patients. Recent omics-based studies have identified early CASP8 somatic alterations, APOBEC mutagenesis, as well as dysregulated immune cell infiltration (decreased CD8+ T cell abundance, enrichment of pro-inflammatory immune cells) as candidate driver events for oral tumor progression from leukoplakia in the same patient. Recent single-cell transcriptomic-driven studies have also identified immune-transcriptomic features as putative driving molecular events in oral tumor development and progression. Here, we reviewed reported differences in driving gene mutations and expression deregulations in disparate and same patient settings. We also highlighted the challenges in sample collection and the opportunity of genomics and transcriptome studies for their emerging role in early diagnosis and progression.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of aggressive B-cell non-Hodgkin lymphoma. While a substantial fraction of patients are cured with frontline chemoimmunotherapy, approximately 30% of cases subsequently relapse. DLBCL immune evasion and refractory disease can occur via several mechanisms: downregulation or loss of major histocompatibility complex expression, immune checkpoint activation, tumor microenvironment modulation, and resistance to apoptosis. Addressing these mechanisms of immune evasion in DLBCL has been a focus of ongoing research, leading to the exploration of new therapies. Here, we review the mechanisms of immune evasion and novel immunotherapy treatment strategies for DLBCL.

Breast cancer metastases to the lower gastrointestinal tract (small bowel and colon) are rare, but there is a growing number of case reports in the literature. The overall incidence of this condition is not well established, and there might be underdiagnosis. The clinical presentation and endoscopic findings are often nonspecific and variable, potentially leading to misdiagnosis or underdiagnosis. Moreover, there are currently no guidelines for gastrointestinal surveillance of these patients. Given the potential diagnostic challenges, a high level of clinical suspicion is necessary. We present a clinical case to highlight subtle endoscopic findings of breast cancer metastasis to the colon, followed by a review summarizing the available literature on breast cancer metastases to the duodenum, jejunum, ileum, colon, rectum, and anus focusing on the clinical presentation, endoscopic features, imaging modalities, treatment, and outcome.

Infection with HPV16, a high-risk human papillomavirus (HPV), can cause cervical cancer in humans. These infections carry a high risk of morbidity and mortality globally in females. This study aimed to conduct an in vivo comparison of Poly (D,L-lactic-co-glycolide) (PLGA)-encapsulated peptide mixture nanoparticles and PLGA microspheres as delivery systems for vaccines.

PLGA polymers were used to form microspheres for a therapeutic vaccine against cervical cancer. The target antigens were the L1 and L2 capsid proteins and the E6 and E7 oncoproteins from HPV16. These antigens were selected based on their immunogenicity, allergenicity, and toxicity. We predicted epitopes for cytotoxic T lymphocytes (CTLs) and helper T lymphocytes. In our investigation of CTL epitopes, we employed synthetic chimeric PLGA microsphere peptides, consisting of multiple H-2Db-restricted HPV16 peptides, coupled with other immune-potentiating adjuvants as predicted by our work.

H-2Db-restricted HPV16 peptides, when administered subcutaneously, enabled CTLs to eliminate in vitro TC-1 tumor cells expressing E6 and E7 of HPV16. Additionally, TC-1 cells protected C57BL/6 mice against in vivo challenges. To address this problem, peptide-based vaccines, which are among the most effective vaccine systems, have been extensively studied. Combining peptide-based vaccinations with microsphere peptide mixture particles and delivery technologies enhances their efficacy in stimulating cellular immune responses and eliminating tumor cells.

This approach may provide a potential therapeutic candidate vaccine based on microsphere-encapsulated peptides for the prevention of cervical cancer caused by HPV.

Alzheimer’s disease (AD), an enduring neurodegenerative malady, contributes significantly to dementia cases, with late-onset AD being more common than early-onset AD. Despite extensive research to diagnose and treat AD, the intricate protein network impedes the development of efficacious drugs or targets. This study endeavored to identify previously undiscovered genetic reservoirs associated with AD progression, which could be targeted as therapeutic markers.

Employing the robust tools of R-language, we dissected vast RNA sequence datasets comprising numerous samples and thousands of genes, pinpointing potential candidates implicated in AD’s trajectory. Thus, we selected the GSE203206 dataset, which includes AD patients and non-dementia controls, based on our criteria. After normalization, RNA-Seq data was compared, and log2fold change was calculated to determine the highly dysregulated genes. Further network analysis of genes and their associated miRNA was performed to determine a characteristic change in control and patient groups.

Differential expression analysis revealed 13 dysregulated genes in AD, wherein 12 were upregulated, and one was down-regulated. Furthermore, we identified hsa-miR-30-5p as a significant miRNA associated with AD, aligning with previous studies and highlighting its high involvement.

This investigation has unveiled four novel genes and a paramount miRNA implicated in AD, thus furnishing potential targets for therapeutic interventions. These discoveries pave the way for further exploration into the intricate functions and implications of these genetic entities in AD.
