Abstract
Chronic wounds constitute an increasingly prevalent global healthcare issue, characterized by recurring bacterial infections, pronounced oxidative stress, compromised functionality of immune cells, unrelenting inflammatory reactions, and deficits in angiogenesis. In response to these multifaceted challenges, the study introduced a stimulus-responsive glycopeptide hydrogel constructed by oxidized Bletilla striata polysaccharide (OBSP), gallic acid-grafted ε-Polylysine (PLY-GA), and paeoniflorin-loaded micelles (MIC@Pae), called OBPG&MP. The hydrogel emulates the structure of glycoprotein fibers of the extracellular matrix (ECM), exhibiting exceptional injectability, self-healing, and biocompatibility. It adapts responsively to the inflammatory microenvironment of chronic wounds, sequentially releasing therapeutic agents to eradicate bacterial infection, neutralize reactive oxygen species (ROS), modulate macrophage polarization, suppress inflammation, and encourage vascular regeneration and ECM remodeling, playing a critical role across the inflammatory, proliferative, and remodeling phases of wound healing. Both in vitro and in vivo studies confirmed the efficacy of OBPG&MP hydrogel in regulating the wound microenvironment and enhancing the regeneration and remodeling of chronic wound skin tissue. This research supports the vast potential for herb-derived multifunctional hydrogels in tissue engineering and regenerative medicine.

Intern Emerg Med 2024; 19:583-588. [PMID: 38158463 DOI: 10.1007/s11739-023-03514-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 12/11/2023] [Indexed: 01/03/2024]
Abstract
AIM The aim of this study was to evaluate the effectiveness and safety of the anti-IL-1 receptor anakinra in patients with chronic active myocarditis refractory to standard therapy. METHODS AND RESULTS In this retrospective, observational study, we enrolled 6 patients with chronically active myocarditis treated with anakinra on-top-of standard treatment. Response to treatment was evaluated at different time points [disease onset (T0), anakinra beginning (T1), three months from anakinra beginning (T2), last available follow-up (T3)], and was assessed by variations in New York Heart Association (NYHA) functional class, laboratory tests [C-reactive protein (CRP), a high-sensitivity cardiac troponin T (cTnT), and Nt-proBNP], left ventricular ejection fraction (LVEF), and cardiac magnetic resonance (CMR) edema or late gadolinium enhancement. The number of premature ventricular complexes (PVCs) at 24-h EKG-recordings was considered in patients with arrhythmic manifestations. No differences were found between T0 and T1 in terms of CRP, Nt-ProBNP, and LVEF. Before anakinra beginning, all patients were still symptomatic. At T2, all patients were symptom-free, in NYHA class I. A significant decrease in CRP (p = 0.03) and a significant improvement in LVEF (p = 0.03) were observed. Sustained arrhythmic manifestations were found in 4 out of 6 patients. In this subgroup, anakinra showed effectiveness in reducing the arrhythmic burden. At T3, the improvement in laboratory values and cardiac function persisted. The arrhythmic burden remained abated. CONCLUSIONS All patients had a rapid improvement in systemic inflammation, cardiac function, and arrhythmic burden with anti-IL1 therapy, indicating that anakinra may be an effective treatment in chronic active idiopathic myocarditis, refractory to standard treatment.

Abstract
Neuroinflammation activated by microglia affects inflammatory pain development. This study aimed to explore the anti-inflammatory properties and mechanisms of 1,6,7-trihydroxy-2-(1,1-dimethyl-2-propenyl)-3-methoxyxanthone (THMX) from Cudrania tricuspidata in microglia activation-mediated inflammatory pain. In RAW 264.7 and BV2 cells, THMX has been shown to reduce lipopolysaccharide (LPS)-induced inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and pro-inflammatory mediators and cytokines, including nitric oxide (NO), prostaglandin (PG) E2, interleukin (IL)-6, and tumor necrosis factor alpha (TNF-α). THMX also decreased LPS-induced phosphorylation of mitogen-activated protein kinase (MAPK) and the activation of p65 nuclear factor kappa B (NF-κB). Interestingly, THMX also activated heme oxygenase (HO)-1 expression. These findings suggest that THMX is a promising biologically active compound against inflammation through preventing MAPKs and NF-ĸB and activating HO-1 signaling pathways.

Abstract
This study investigated the mechanisms of Jingfang Granule (JFG) in viral myocarditis (VMC) treatment via network pharmacology-based approach combined with molecular docking and validated the results through in vitro and in vivo experiments. The chemical composition of JFG and its therapeutic targets was queried in Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. The targets related to VMC were retrieved from the disease database, and the overlapping targets were screened. Based on the STRING database, a protein-protein interaction network was constructed. Cytoscape software was used to construct the "component-target-disease" interaction network for visualization. GO and KEGG pathway enrichment analyses were performed using Metascape data. Molecular docking was performed using PyMoL2.3.0 and AutoDock Vina software programs. The target genes were further verified in vitro and in vivo. JFG contains 88 active components. The main biological targets of JFG in VMC include quercetin, luteolin, and kaempferol. The molecular docking results showed that the three key targets showed strong binding properties with both the height components of the molecular docking interaction energies. The results of experimental verification results showed that JFG may be used to treat VMC mainly by down-regulating inflammatory factors TNF-α and NF-κB and inhibiting myocardial apoptosis. The results support the network pharmacological data. JFG reduces myocardial inflammation and myocardial cell apoptosis in VMC and protects myocardial tissue.

Abstract
Signal transducer and activator of transcription 3 (STAT3), an important transcription factor and signaling molecule, play an important role in cardiac disease and protection. As a transcription factor, STAT3 upregulates anti-oxidative and anti-apoptotic genes but suppresses anti-inflammatory and anti-fibrotic genes in cardiac disease and protection. As a signaling molecule, STAT3 is the downstream or upstream of other molecules for signaling transduction, also activated in cardiac disease and protection. MicroRNAs (miRNAs) are endogenous short non-coding RNAs that regulate mRNA expression at the transcriptional level and prevent protein translation. Recently, STAT3 is reported to be not only the target of miRNA but also the inhibitor or inducer of miRNA to modify the mRNA expression profiles in cardiomyocytes resulting in different effects on cardiac disease and protection. We summarize the current knowledge on STAT3 regulation of individual miRNAs and the modulation of STAT3 by miRNAs in cardiac diseases and protection.

Abstract
BACKGROUND The newly identified betacoronavirus SARS-CoV-2 is the causative pathogen of the 2019 coronavirus disease (COVID-19), which has killed more than 4.5 million people. SARS-CoV-2 causes severe respiratory distress syndrome by targeting the lungs and also induces myocardial damage. Shenshao Ningxin Yin (SNY) has been used for more than 700 years to treat influenza. Previous randomized controlled trials (RCTs) have demonstrated that SNY can improve the clinical symptoms of viral myocarditis, reverse arrhythmia, and reduce the level of myocardial damage markers. METHODS This work uses a rational computational strategy to identify existing drug molecules that target host pathways for the treatment of COVID-19 with myocarditis. Disease and drug targets were input into the STRING database to construct proteinɃprotein interaction networks. The Metascape database was used for GO and KEGG enrichment analysis. RESULTS SNY signaling modulated the pathways of coronavirus disease, including COVID-19, Ras signaling, viral myocarditis, and TNF signaling pathways. Tumor necrosis factor (TNF), cellular tumor antigen p53 (TP53), mitogen-activated protein kinase 1 (MAPK1), and the signal transducer and activator of transcription 3 (STAT3) were the pivotal targets of SNY. The components of SNY bound well with the pivotal targets, indicating there were potential biological activities. CONCLUSION Our findings reveal the pharmacological role and molecular mechanism of SNY for the treatment of COVID-19 with myocarditis. We also, for the first time, demonstrate that SNY displays multi-component, multi-target, and multi-pathway characteristics with a complex mechanism of action.

Abstract
Self-assemblies of bioactively natural compounds into supramolecular hydrogels without structural modifications are of interest to improve their sustained releases and bioavailabilities in vivo. However, it is still a formidable challenge to dig out such a naturally small molecule with a meticulous structure which can be self-assembled to form a hydrogel for biomedical applications. Here, a new hydrogel consisting only of gallic acid (GA) via π-π stacking and hydrogen bond interactions, whereas none of GA analogues can form the similar supramolecular hydrogels, is reported. This interesting phenomenon is intriguing to further investigate the potential applications of GA hydrogels in wound healing. Notably, this GA hydrogel has rod-like structures with lengths varying from 10 to 100 µm. The biocompatibility and antibacterial tests prove that this well-assembled GA hydrogel has no cytotoxicity and excellent antibacterial activities against Escherichia coli and Staphylococcus aureus. Moreover, the GA hydrogel can significantly accelerate the process of wound healing with or without bacterial infections by mediation of inflammation signaling pathways. It is believed that the current study may shed a new light on the design of a supramolecular hydrogel based on self-assemblies of naturally small molecules to improve their bioavailabilities and diversify their uses in biomedical applications.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can target cardiomyocytes (CMs) to directly invade the heart resulting in high mortality. This study aims to explore the biological characteristics of SARS-CoV-2 infected myocardium based on omics by collecting transcriptome data and analyzing them with a series of bioinformatics tools. Totally, 86 differentially expressed genes (DEGs) were discovered in SARS-CoV-2 infected CMs, and 15 miRNAs were discovered to target 60 genes. Functional enrichment analysis indicated that these DEGs were mainly enriched in the inflammatory signaling pathway. After the protein-protein interaction (PPI) network was constructed, several genes including CCL2 and CXCL8 were regarded as the hub genes. SRC inhibitor saracatinib was predicted to potentially act against the cardiac dysfunction induced by SARS-CoV-2. Among the 86 DEGs, 28 were validated to be dysregulated in SARS-CoV-2 infected hearts. Gene Set Enrichment Analysis (GSEA) analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) showed that malaria, IL-17 signaling pathway, and complement and coagulation cascades were significantly enriched. Immune infiltration analysis indicated that ‘naive B cells’ was significantly increased in the SARS-CoV-2 infected heart. The above results may help to improve the prognosis of patients with COVID-19.

Abstract
Renal interstitial fibrosis (RIF) is the common irreversible pathway by which chronic kidney disease (CKD) progresses to the end stage. The transforming growth factor-β (TGF-β)/signal transducer and activator of transcription 3 (STAT3) signaling pathway is a common factor leading to inflammation-mediated RIF, but its downstream regulatory mechanism is still unclear. Bioinformatics analysis predicted that serum amyloid A protein 1 (SAA1) was one of the target genes for transcriptional activation of STAT3 signaling. As an acute phase reaction protein, SAA1 plays an important role in many inflammatory reactions, and research has suggested that SAA1 is significantly elevated in the serum of patients with CKD. In this research, multiple experiments were performed to investigate the role of SAA1 in the process of RIF. SAA1 was abnormally highly expressed in kidney tissue from individuals who underwent unilateral ureteral obstruction (UUO) and TGF-β-induced HK2 cells, and the abnormal expression was directly related to the transcriptional activation of STAT3. Additionally, SAA1 can directly target and bind valosin-containing protein (VCP)-interacting membrane selenoprotein (VIMP) to inhibit the function of the Derlin-1/VCP/VIMP complex, preventing the transportation and degradation of the misfolded protein, resulting in endoplasmic reticulum (ER) stress characterized by an increase in glucose-regulated protein 78 (GRP78) levels and ultimately promoting the occurrence and development of RIF.
