ABSTRACT
Objective To explore the core targets and important pathways of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) induced atherosclerosis (AS) progression from the perspective of immune inflammation, so as to predict the potential prevention and treatment of traditional Chinese medicine (TCM). Methods Microarray data were obtained from the Gene Expression Omnibus (GEO) database for coronavirus disease 2019 (COVID-19) patients and AS patients, and the "limmar" and "Venn" packages were used to screen out the common differentially expressed genes (DEGs) genes in both diseases. The gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) analyses were performed on the common DEGs to annotate their functions and important pathways. The two gene sets were scored for immune cells and immune function to assess the level of immune cell infiltration. The protein-protein interaction (PPI) network was constructed by STRING database, and the CytoHubba plug-in of Cytoscape was used to identify the hub genes. Two external validation datasets were introduced to validate the hub genes and obtain the core genes. Immuno-infiltration analysis and gene set enrichment analysis (GSEA) were performed on the core genes respectively. Finally the potential TCM regulating the core genes were predicted by Coremine Medical database. Results A total of 7898 genes related to COVID-19, 471 genes related to AS progression;And 51 common DEGs, including 32 highly expressed genes and 19 low expressed genes were obtained. GO and KEGG analysis showed that common DEGs, which were mainly localized in cypermethrin-encapsulated vesicles, platelet alpha particles, phagocytic vesicle membranes and vesicles, were involved in many biological processes such as myeloid differentiation factor 88 (MyD88)-dependent Toll-like receptor signaling pathway transduction, interleukin-8 (IL-8) production and positive regulation, IL-6 production and positive regulation to play a role in regulating nicotinamide adenine dinucleotide phosphate oxidase activity, Toll-like receptor binding and lipopeptide and glycosaminoglycan binding through many biological pathways, including Toll-like receptor signaling pathways, neutrophil extracellular trap formation, complement and coagulation cascade reactions. The results of immune infiltration analysis demonstrated the state of immune microenvironment of COVID-19 and AS. A total of 5 hub genes were obtained after screening, among which Toll-like receptor 2 (TLR2), cluster of differentiation 163 (CD163) and complement C1q subcomponent subunit B (C1QB) genes passed external validation as core genes. The core genes showed strong correlation with immune process and inflammatory response in both immune infiltration analysis and GSEA enrichment analysis. A total of 35 TCMs, including Chuanxiong (Chuanxiong Rhizoma), Taoren (Persicae Semen), Danggui (Angelicae Sinensis Radix), Huangqin (Scutellariae Radix), Pugongying (Taraxaci Herba), Taizishen (Pseudostellariae Radix), Huangjing (Polygonati Rhizoma), could be used as potential therapeutic agents. Conclusion TLR2, CD163 and C1QB were the core molecules of SARS-CoV-2-mediated immune inflammatory response promoting AS progression, and targeting predicted herbs were potential drugs to slow down AS progression in COVID-19 patients.Copyright © 2023 Editorial Office of Chinese Traditional and Herbal Drugs.

ABSTRACT
Introduction: We report a case of drug-induced liver injury (DILI) induced by cannabis gummies containing Corydalis Rhizome. Case Description/Methods: A 37-year-old female presented to her primary care clinic with recurrent fevers, night sweats, and myalgias for 7 weeks accompanied by eye redness, brain fog, headache, nausea, and abdominal pain. She denied rashes, tick-bites, cough, dyspnea, chest pain, joint swelling, or genitourinary symptoms. Past medical history was notable for IBS, migraines, and anxiety. She reported edible marijuana use four times a week, rare alcohol use, and denied tobacco use. She denied a family history of liver disease. Physical exam was notable for tachycardia to 110 and scleral injection with the remainder of vitals and exam unremarkable. Initial labs were notable for AST 61, ALT 44 and CRP of 12. CBC, BMP, urinalysis, ESR, blood cultures, blood smear for parasite screen, tests for Lyme disease, Babesia, Tularemia, Anaplasma, Ehrlichia, Rickettsia, EBV, HIV, RPR, ANA, CMV, parvovirus B19, and chest x-ray were all negative. The patient was referred to infectious disease with further testing for West Nile, Leptospira, lymphocytic choriomeningitis virus, and COVID-19 returning negative. Repeat LFTs showed worsening transaminitis with ALT 979 and AST 712, alkaline phosphatase 88, total bilirubin 0.7, and albumin 4.9. Hepatitis workup including hepatitis A, B, and C, HSV, EBV, VZV serologies, AMA, ASMA, antiLKM Ab, acetaminophen level, INR, iron panel, CPK, TSH, and abdominal ultrasound were all normal. It was later discovered that her marijuana gummies contained Corydalis rhizome extract known to be hepatotoxic. Cessation of this drug was strongly advised. She was discharged with hepatology follow-up and underwent a liver biopsy showing patchy periportal and lobular inflammation with extension across the limiting plate, hepatocyte injury and apoptosis, and increased lipofuscin for age compatible with mild to moderate hepatitis. She had complete recovery after cessation of Corydalis-containing gummies. (Figure) Discussion: Our patient consumed '1906 Midnight', an American cannabis brand containing Corydalis rhizopus 100 mg, advertised to improve sleep, pain, and have a liver protective effect. A Korean systematic review on herbal-induced liver injury reported that Corydalis was the 3rd most frequent causative herb, with 36 cases. Although there are several personal accounts on social networking sites and other websites, there are no American-based publications reported on DILI from Corydalis. (Table Presented).

ABSTRACT
COVID-19 is a deadly disease which has become a global issue in the recent years. At present, the whole world is trying to combat the disease and scientific communities are putting rigorous efforts in developing 100 per cent effective treatment. Though some synthetic drugs are eff icient in controlling the COVID-19, they possess numerous side effects on human body. In these consequences, there is a global need to search for the natural agents that can act against COVID-19 as a precautionary measure which can improve our immunity and also to control the COVID-19 at various stages of infection. Curcuminoids (curcumin, demethoxycurcumin and bisdemethoxycurcumin) are naturally derived plant compounds from turmeric rhizomes and are having the ability to f ight against COVID-19. Earlier studies have focused on docking of curcuminoids against spike protein and main protease of COVID-19. In the present study, docking of curcuminoids against four COVID-19 proteins and one human receptor has been studied. The efficiency of curcuminoids was compared with that of synthetic drugs. Results clearly showed the potentiality of curcuminoids against COVID-19 and can be used as an alternative to the existing synthetic drugs after sufficient clinical trials.

ABSTRACT
Curcumae Longae Rhizoma (CLR) is the rhizome of Curcuma longa L. Pharmacological studies show that CLR can be used to treat cervical cancer, lung cancer, lupus nephritis, and other conditions. In this paper, we review botany, traditional application, phytochemistry, pharmacological activity, and pharmacokinetics of CLR. The literature from 1981 to date was entirely collected from online databases, such as Web of Science, Google Scholar, China Academic Journals full-text database (CNKI), Wiley, Springer, PubMed, and ScienceDirect. The data were also obtained from ancient books, theses and dissertations, and Flora Reipublicae Popularis Sinicae. There are a total of 275 compounds that have been isolated from CLR, including phenolic compounds, volatile oils, and others. The therapeutic effect of turmeric has been expanded from breaking blood and activating qi in the traditional sense to antitumor, anti-inflammatory, antioxidation, neuroprotection, antibacterial, hypolipidemic effects, and other benefits. However, the active ingredients and mechanisms of action related to relieving disease remain ill defined, which requires more in-depth research and verification at a clinical level.

ABSTRACT
In the face of the COVID-19 pandemic, there is still a lack of miracle drugs for treatment. Repurposing drugs such as Remdesivir and corticosteroids to treat COVID-19 are being studied. Traditional Chinese medicine was widely used during the outbreak of Severe Acute Respiratory Syndrome (SARS) coronavirus infection in China in 2003. It was found that standard medical treatment combined with Chinese medicine treatment may improve the symptoms of SARS patients and speeding resolution of lung infiltration. The commonly used prescriptions for preventing the coronavirus infection are Sangjuyin plus Yupingfeng powder. Various Traditional Chinese medicines with potential to fight SARS-CoV-2 include Liquorice Root and Rhizome, Rhubarb, Heartleaf Houttuynia Herb, Indi-gowoad Root, Tangerine Peel, Scutellaria Root, and Red Sage Root and Rhizome etc. In addition, Chinese patent medicines including Shuanghuanglian Oral liquid, Lianhua Qingwen Capsule, Jinhua Qinggan Granule and Taiwan Chingguan Yihau are recognized as plausible agents for the treatment of novel coronavirus pneumonia. The antiviral, anti-inflammatory and immunomodulatory effects of selected Chinese herbal drugs may attribute to their inhibiting the binding of the coronavirus spike protein to the angiotensin-converting enzyme 2 (ACE2) receptor, inhibiting key enzymes such as 3-chymotrypsin-like protease and ribonucleic acid (RNA)- dependent RNA polymerase during viral replication, and reducing pro-inflammatory cytokines. Since most of the relevant studies mentioned the potential anti-SARS-CoV-2 activity of these agents were only in vitro and animal experiments, more randomized double-blind controlled trials are needed to provide reliable evidence of clinical efficacy in future.
ABSTRACT
This essay considers how insights into the dynamic, interconnected, and high-stakes nature of frontier markets resonate with current disruptions in global commodity networks. In the book Unsettled Frontiers (Cornell University Press, 2022), I argue that the tangled social and material networks that constitute frontier markets are prone to rupture—a characteristic that holds significant implications for frontier landscapes and communities. Such processes of rupture—consequential and unequal in their effects—are evident in the disruptions we now see in the wake of Covid-19 and the broader unfolding of our current nature–society crisis. © 2022, Japan Focus.

ABSTRACT
Coronavirus disease 2019 (COVID-19), a viral infectious respiratory disease, is caused by highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is responsible for the ongoing COVID-19 pandemic. Since very few drugs are known to be effective against SARS-CoV-2, there is a general need for new therapeutics, including plant-based drugs, for the prophylaxis and treatment of infections. In the current study, the activity of a 70% ethanolic(aq) extract of the rhizome bark of Japanese knotweed, an invasive alien plant species, was tested for the first time against the wild-type SARS-CoV-2 virus using a specific and robust virus neutralization test (VNT) on Vero-E6 cells, which best mimics the mechanism of real virus-host interaction. A statistically significant antiviral effect against SARS-CoV-2 (p-value < 0.05) was observed for the 50.8 µg mL-1 extract solution in cell medium. A suitable extract preparation was described to avoid loss of polyphenols throughout filtration of the extract, which was dissolved in cell medium containing fetal bovine serum (FBS). The significance of the differences between the sums of the test and control groups in the incidence of cytopathic effects (CPE) was determined using the one-way ANOVA test. A dose-response relationship was observed, with the cytotoxic effect occurring at higher concentrations of the extract (≥101.6 µg mL-1). The obtained results suggest possible use of this plant material for the production of various products (e.g., packaging, hygiene products, biodisinfectants, etc.) that would be useful against the spread of and for self-protection against COVID-19.

ABSTRACT
Pneumonia refers to a death-causing infection. Astragali Radix (AR) and Atractylodis Macrocephalae Rhizoma (AMR) are widely used as traditional tonic and promising edible immunomodulatory herbal medicine, but the systemic mechanism is not well understood. Therefore, a strategy based on network pharmacology and molecular docking was designed to explore the systemic mechanism of AR-AMR acting on pneumonia. After a series of bioinformatics assays, seven kernel targets were obtained, including TNF, IL6, IFNG, IL1B, IL10, IL4, and TLR9. And seven key compounds were identified as the synergy components of AR-AMR acting on pneumonia, the four key compounds belonging to AR were (3R)-3-(2-hydroxy-3,4-dimethoxyphenyl)-7-chromanol, formononetin, quercetin, and kaempferol, the three key compounds belonging to AMR were atractylone, 14-acetyl-12-senecioyl-2E, 8E, 10E-atractylentriol, and α-Amyrin. The crucial pathways were mainly related to three modules, including immune diseases, infectious disease, and organismal systems. Collectively, these observations strongly suggest that the molecular mechanisms of AR-AMR regulating pneumonia were closely related to the correlation between inflammation and immune response. PRACTICAL APPLICATIONS: Astragali radix and Atractylodis macrocephalae rhizoma can be used as "medicine-food homology" for dietary supplement. AR and AMR are widely used as a traditional tonic and promising edible immunomodulatory herbal medicine. The AR-AMR herb pairs are used for compatibility many times in the recommended prescriptions in COVID-19 develop pneumonia in China. However, the ingredients and mechanisms of AR-AMR acting on Pneumonia via immunomodulation are unclear. In this paper, bioinformatics and network biology were used to systematically explore the mechanisms of the AR-AMR herb pairs in treatment of pneumonia, and further analyze the correlation mechanism between it and COVID-19 develop pneumonia. To sum up, our study reveals the interrelationships between components, targets, and corresponding biological processes of AR-AMR acting on pneumonia. Understanding these relationships may provide guidance and theoretical basis for the further application of AR-AMR herb pairs.
