Qingkailing granule alleviates pulmonary fibrosis by inhibiting PI3K/AKT and SRC/STAT3 signaling pathways.

Pulmonary fibrosis (PF) poses a significant challenge with limited treatment options and a high mortality rate of approximately 45 %. Qingkailing Granule (QKL), derived from the Angong Niuhuang Pill, shows promise in addressing pulmonary conditions. Using a comprehensive approach, combining network pharmacology analysis with experimental validation, this study explores the therapeutic effects and mechanisms of QKL against PF for the first time. In vivo, QKL reduced collagen deposition and suppressed proinflammatory cytokines in a bleomycin-induced PF mouse model. In vitro studies demonstrated QKL's efficacy in protecting cells from bleomycin-induced injury and reducing collagen accumulation and cell migration in TGF-ß1-induced pulmonary fibrosis cell models. Network pharmacology analysis revealed potential mechanisms, confirmed by western blotting, involving the modulation of PI3K/AKT and SRC/STAT3 signaling pathways. Molecular docking simulations highlighted interactions between QKL's active compounds and key proteins, showing inhibitory effects on epithelial damage and fibrosis. Collectively, these findings underscore the therapeutic potential of QKL in alleviating pulmonary inflammation and fibrosis through the downregulation of PI3K/AKT and SRC/STAT3 signaling pathways, with a pivotal role attributed to its active compounds.

A ternary correlation multi-symptom network strategy based on in vivo chemical profile identification and metabolomics to explore the molecular basis of Ephedra herb against viral pneumonia.

Ephedra herb (EH), an important medicine prescribed in herbal formulas by Traditional Chinese Medicine practitioners, has been widely used in the treatment of viral pneumonia in China. However, the molecular basis of EH in viral pneumonia remains unclear. In this study, a ternary correlation multi-symptom network strategy was established based on in vivo chemical profile identification and metabolomics to explore the molecular basis of EH against viral pneumonia. Results showed that 143 compounds of EH and 70 prototype components were identified in vivo. EH could reduce alveolar-capillary barrier disruption in rats with viral pneumonia and significantly downregulate the expression of inflammatory factors and bronchoalveolar lavage fluid. Plasma metabolomics revealed that EH may be involved in the regulation of arachidonic acid, tryptophan, tyrosine, nicotinate, and nicotinamide metabolism. The multi-symptom network showed that 12 compounds have an integral function in the treatment of viral pneumonia by intervening in many pathways related to viruses, immunity and inflammation, and lung injury. Further verification demonstrated that sinapic acid and frambinone can regulate the expression of related genes. It has been shown to be a promising representative of the pharmacological constituents of ephedra.

Exploring the Blood Biomarkers and Potential Therapeutic Agents for Human Acute Mountain Sickness Based on Transcriptomic Analysis, Inflammatory Infiltrates and Molecular Docking.

A high-altitude, low-pressure hypoxic environment has severe effects on the health and work efficiency of its residents, and inadequate preventive measures and adaptive training may lead to the occurrence of AMS. Acute exposure to hypoxia conditions can have a less-favorable physiological effect on the human immune system. However, the regulation of the immune system in high-altitude environments is extremely complex and remains elusive. This study integrated system bioinformatics methods to screen for changes in immune cell subtypes and their associated targets. It also sought potential therapeutically effective natural compound candidates. The present study observed that monocytes, M1 macrophages and NK cells play a crucial role in the inflammatory response in AMS. IL15RA, CD5, TNFSF13B, IL21R, JAK2 and CXCR3 were identified as hub genes, and JAK2 was positively correlated with monocytes; TNFSF13B was positively correlated with NK cells. The natural compound monomers of jasminoidin and isoliquiritigenin exhibited good binding affinity with JAK2, while dicumarol and artemotil exhibited good binding affinity with TNFSF13B, and all are expected to become a potential therapeutic agents.

Mechanism Actions of Coniferyl Alcohol in Improving Cardiac Dysfunction in Renovascular Hypertension Studied by Experimental Verification and Network Pharmacology.

Renovascular hypertension (RH), a secondary hypertension, can significantly impact heart health, resulting in heart damage and dysfunction, thereby elevating the risk of cardiovascular diseases. Coniferol (CA), which has vascular relaxation properties, is expected to be able to treat hypertension-related diseases. However, its potential effects on cardiac function after RH remain unclear. In this study, in combination with network pharmacology, the antihypertensive and cardioprotective effects of CA in a two-kidney, one-clip (2K1C) mice model and its ability to mitigate angiotensin II (Ang II)-induced hypertrophy in H9C2 cells were investigated. The findings revealed that CA effectively reduced blood pressure, myocardial tissue damage, and inflammation after RH. The possible targets of CA for RH treatment were screened by network pharmacology. The interleukin-17 (IL-17) and tumor necrosis factor (TNF) signaling pathways were identified using a Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The inflammatory response was identified using a Gene Ontology (GO) enrichment analysis. Western blot analysis confirmed that CA reduced the expression of IL-17, matrix metallopeptidase 9 (MMP9), cyclooxygenase 2 (COX2), and TNF α in heart tissues and the H9C2 cells. In summary, CA inhibited cardiac inflammation and fibrohypertrophy following RH. This effect was closely linked to the expression of MMP9/COX2/TNF α/IL-17. This study sheds light on the therapeutic potential of CA for treating RH-induced myocardial hypertrophy and provides insights into its underlying mechanisms, positioning CA as a promising candidate for future drug development.

Traditional Chinese Medicine Compound (Tongxinluo) and Clinical Outcomes of Patients With Acute Myocardial Infarction: The CTS-AMI Randomized Clinical Trial.

Importance: Tongxinluo, a traditional Chinese medicine compound, has shown promise in in vitro, animal, and small human studies for myocardial infarction, but has not been rigorously evaluated in large randomized clinical trials. Objective: To investigate whether Tongxinluo could improve clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Design, Setting, and Participants: Randomized, double-blind, placebo-controlled clinical trial was conducted among patients with STEMI within 24 hours of symptom onset from 124 hospitals in China. Patients were enrolled from May 2019 to December 2020; the last date of follow-up was December 15, 2021. Interventions: Patients were randomized 1:1 to receive either Tongxinluo or placebo orally for 12 months (a loading dose of 2.08 g after randomization, followed by the maintenance dose of 1.04 g, 3 times a day), in addition to STEMI guideline-directed treatments. Main Outcomes and Measures: The primary end point was 30-day major adverse cardiac and cerebrovascular events (MACCEs), a composite of cardiac death, myocardial reinfarction, emergent coronary revascularization, and stroke. Follow-up for MACCEs occurred every 3 months to 1 year. Results: Among 3797 patients who were randomized, 3777 (Tongxinluo: 1889 and placebo: 1888; mean age, 61 years; 76.9% male) were included in the primary analysis. Thirty-day MACCEs occurred in 64 patients (3.4%) in the Tongxinluo group vs 99 patients (5.2%) in the control group (relative risk [RR], 0.64 [95% CI, 0.47 to 0.88]; risk difference [RD], -1.8% [95% CI, -3.2% to -0.6%]). Individual components of 30-day MACCEs, including cardiac death (56 [3.0%] vs 80 [4.2%]; RR, 0.70 [95% CI, 0.50 to 0.99]; RD, -1.2% [95% CI, -2.5% to -0.1%]), were also significantly lower in the Tongxinluo group than the placebo group. By 1 year, the Tongxinluo group continued to have lower rates of MACCEs (100 [5.3%] vs 157 [8.3%]; HR, 0.64 [95% CI, 0.49 to 0.82]; RD, -3.0% [95% CI, -4.6% to -1.4%]) and cardiac death (85 [4.5%] vs 116 [6.1%]; HR, 0.73 [95% CI, 0.55 to 0.97]; RD, -1.6% [95% CI, -3.1% to -0.2%]). There were no significant differences in other secondary end points including 30-day stroke; major bleeding at 30 days and 1 year; 1-year all-cause mortality; and in-stent thrombosis (<24 hours; 1-30 days; 1-12 months). More adverse drug reactions occurred in the Tongxinluo group than the placebo group (40 [2.1%] vs 21 [1.1%]; P = .02), mainly driven by gastrointestinal symptoms. Conclusions and Relevance: In patients with STEMI, the Chinese patent medicine Tongxinluo, as an adjunctive therapy in addition to STEMI guideline-directed treatments, significantly improved both 30-day and 1-year clinical outcomes. Further research is needed to determine the mechanism of action of Tongxinluo in STEMI. Trial Registration: ClinicalTrials.gov Identifier: NCT03792035.

[Inheritance, innovation and development of traditional Chinese medicine in new era call for scientific supervision].

Pharmaceutical products need to ensure the effectiveness, safety and quality controllability through scientific supervision, and as the broad masses of the people are full of new expectations for the supply of high-quality traditional Chinese medicine products, the reform and innovation of traditional Chinese medicine regulatory policies are also facing new opportunities and new challenges. National Medical Products Administration, National Administration of Traditional Chinese Medicine and other relevant departments have implemented the requirements of the Party Central Committee and the State Council, vigorously promoted the reform of the regulatory system in line with the characteristics of traditional Chinese medicine, introduced a series of innovative policies, and achieved phased results. Including the new registration classification standards in line with the characteristics of traditional Chinese medicine, encouraging the development of classical formulas and hospital preparations, encouraging the research and development of symptomatic Chinese medicines, and gra-dually improving the "three-combined " evidence system. However, in the face of the development problems of traditional Chinese medicine in the new era, it is still necessary to improve the scientific supervision system, further optimize the management measures for the registration of traditional Chinese medicines based on classical formulas, accelerate the improvement of the standard system for traditional Chinese medicine formula granules, and form management measures to encourage and support the secondary development of traditional Chinese medicines. In terms of scientific supervision of traditional Chinese medicine, it is necessary to follow the characteristics and development laws of traditional Chinese medicine itself, comprehensively consider the characteristics of epochal, scientific and systematic in regulatory policies, and serve the inheritance and innovative development of traditional Chinese medicine with scientific supervision.

Memory-like response in platelet attenuates platelet hyperactivation in arterial thrombosis.

Recent studies showed that in responding of pathogens stimulation, immune cells and other cells display memory-like effects. Platelets are primary effectors of hemostasis and thrombosis which also participate in immune responses. However, there is no relevant research on whether memory-like effect exists in platelets. In our study after recovery from repetitive LPS stimulus, platelets aggregation, diffusion and clot retraction exhibit a significant reduction. It proves that memory-like response could be aroused in platelets. Furthermore, in the mouse arterial thrombosis model, LPS pretreated platelets showed lower integrin activation, shorter thrombus length and longer occlusion time, indicating that the memory-like response of platelet could alleviate arterial thrombosis. Moreover, memory-like response of platelets was also found to be related to PI3K/AKT signaling pathway. The decreased mitochondrial DNA methylation reveal that platelet memory-like responses may be produced from epigenetic reprogramming. Our research proves for the first time that memory-like response in platelets protects mice from arterial thrombosis, extends the understanding of trained memory.

[Theoretical innovation of component-based Chinese medicine and its exemplary practice: the study on creating Guanxinning Tablets].

Upholding the wisdom of traditional Chinese medicine that the therapeutic principle, method, formula and medicine are coherent with each other, we propose the technical methodology for intelligent creation of component-based Chinese medicine by integrating multidisciplinary knowledge such as artificial intelligence, pharmaceutical informatics, system pharmacology and phytochemistry. Taking the creation of Guanxinning Tablets as an example, we expound the technical principle for creating component-based Chinese medicine and briefly describe the design method for optimizing the entity of Chinese medicine efficacy by rational combination of active components. Our research sought to "clarify and explain" the mechanism of its clinical treatment action through multi-modal and multi-scale systematic pharmacology studies. This work emphatically demonstrates the pilot workshop and engineering validation platform based on the intelligent simulation of whole production process, and outlines the design principles of the intelligent production line for innovative Chinese medicine. The results of industrial research show that the ourself established method for evaluating the process quality controllability and intelligent production line can be applied to manufacturing Guanxining Tablets with high quality. Through the innovative research of multidisciplinary cross-border integration, the present work explored a new way for the creation of modern Chinese medicine.

[Risk assessment, safe medication and scientific supervision of traditional Chinese medicine containing aristolochic acids--toxicity is different among aristolochic acids, and detection and control of aristolochic acid â /â ¡ is critical].

The safety problem of traditional Chinese medicine containing aristolochic acid is of great concern in China and abraod, which poses a challenge in clinical application and supervision. There are many types of aristolochic acid analogues(AAAs) and 178 have been reported. According to the structure, they are classified into aristolochic acids(AAs) and aristololactams(ALs). The toxi-city is remarkably different among AAAs of different types. For example, AA-Ⅰ has strong nephrotoxicity and carcinogenicity, and the toxicity of AA-Ⅱ is lower than that of AA-Ⅰ. Besides, AA-Ⅳa and AA-Ⅰa are considered to have no obvious nephrotoxicity and carcinogenicity. The types and content of AAAs are significantly different among traditional Chinese medicines derived from different Aristolochiaceae species. For example, Asari Radix et Rhizoma and Aristolochiae Herba mainly consist of AAAs without obvious toxicity(such as AA-Ⅳa). The content of AAAs in compound preparations is related to the proportions of the medicinals and the processing method. The content of AA-Ⅰ in some compound preparations is very low or below the detection limit. Therefore, the author concludes that AAAs of different types have different toxicity, but not all AAAs has nephrotoxicity and carcinogenicity. Moreover, the toxicity of traditional Chinese medicines containing AAAs should not be generalized and AA-Ⅰ and AA-Ⅱ should be emphasized. In this paper, it is suggested that traditional Chinese medicine containing AAAs should be used rationally and research, analysis, and toxicological study of AAAs species and content should be strengthened. In addition, limit standards of AA-Ⅰ and AA-Ⅱ should be formulated and science-based supervision should be performed.

Comparison and Analysis on the Existing Single-Herbal Strategies against Viral Myocarditis.

Purpose: Herbal medicine is one of crucial symbols of Chinese national medicine. Investigation on molecular responses of different herbal strategies against viral myocarditis is immeasurably conducive to targeting drug development in the current international absence of miracle treatment. Methods: Literature retrieval platforms were applied in the collection of existing empirical evidences for viral myocarditis-related single-herbal strategies. SwissTargetPrediction, Metascape, and Discovery Studio coordinating with multidatabases investigated underlying target genes, interactive proteins, and docking molecules in turn. Results: Six single-herbal medicines consisting of Huangqi (Hedysarum Multijugum Maxim), Yuganzi (Phyllanthi Fructus), Kushen (Sophorae Flavescentis Radix), Jianghuang (Curcumaelongae Rhizoma), Chaihu (Radix Bupleuri), and Jixueteng (Spatholobus Suberectus Dunn) meet the requirement. There were 11 overlapped and 73 unique natural components detected in these herbs. SLC6A2, SLC6A4, NOS2, PPARA, PPARG, ACHE, CYP2C19, CYP51A1, and CHRM2 were equally targeted by six herbs and identified as viral myocarditis-associated symbols. MCODE algorithm exposed the hub role of SRC and EGFR in strategies without Jianghuang. Subsequently, we learned intermolecular interactions of herbal components and their targeting heart-tissue-specific CHRM2, FABP3, TNNC1, TNNI3, TNNT2, and SCN5A and cardiac-myocytes-specific IL6, MMP1, and PLAT coupled with viral myocarditis. Ten interactive characteristics such as π-alkyl and van der Waals were modeled in which ARG111, LYS253, ILE114, and VAL11 on cardiac troponin (TNNC1-TNNI3-TNNT2) and ARG208, ASN106, and ALA258 on MMP1 fulfilled potential communicating anchor with ellagic acid, 5α, 9α-dihydroxymatrine, and leachianone g via hydrogen bond and hydrophobic interaction, respectively. Conclusions: The comprehensive outcomes uncover differences and linkages between six herbs against viral myocarditis through component and target analysis, fostering development of drugs.

Capsaicin on stem cell proliferation and fate determination - a novel perspective.

Capsaicin (CAP), a member of the vanilloid family, is the main active component of chili peppers, which has been widely explored for its various pharmacological effects and influence on cell physiology, such as axonal growth and apoptosis of tumor cells. In particular, CAP plays a crucial role in determining the proliferation and fate specification of stem cells by modulating a variety of signaling pathways, such as PPARγ, C/EBPα and Notch signaling. Since CAP-mediated processes are complex and multifactorial, we hope to achieve a better understanding of these processes and their implications in clinical applications. This review aims to shed light on the influences and mechanisms of CAP on the actions of various stem cells in adults and discusses the role of CAP in the different process of stem cell behaviors, including proliferation and differentiation. Our purpose is to provide certain prospects for the application of CAP and stem cell therapy in treating diseases.

Pharmacological potential of the combination of Salvia miltiorrhiza (Danshen) and Carthamus tinctorius (Honghua) for diabetes mellitus and its cardiovascular complications.

Metabolic syndrome, such as diabetes mellitus, obesity, atherosclerosis, and high blood pressure (HBP), are closely linked pathophysiologically. However, current monotherapies for metabolic syndrome fail to target the multifactorial pathology via multiple mechanisms, as well as resolving the dysfunctionality of the cells and organs of the body. We aimed to provide a comprehensive and up-to-date review of the pharmacological advances, therapeutic potential, and phytochemistry of Salvia miltiorrhiza, Carthamus tinctorius, and Danhong injection (DHI). We discussed the molecular mechanisms of the bioactive constituents relating to diabetes mellitus and metabolic disease for further research and drug development. Interestingly, Salvia miltiorrhiza, Carthamus tinctorius, and DHI have anti-inflammatory, anti-glycemic, anti-thrombotic, and anti-cancer properties; and they mainly act by targeting the dysfunctional vasculatures including the inflammatory components of the disease to provide vascular repair as well as resolving oxidative stress. The major bioactive chemical constituents of these plants include polyphenolic acids, diterpene compounds, carthamin, and hydroxysafflor yellow A. Treatment of diabetes mellitus and its associated cardiovascular complication requires a comprehensive approach involving the use of appropriate traditional Chinese medicine formula. Danshen, Honghua, and DHI target the multiple risk factors regulating the physiologic function of the body and restore normalcy, apart from the traditional advice on exercise and diet control as treatment options in a metabolic syndrome patient.

Entecavir as a P2X7R antagonist ameliorates platelet activation and thrombus formation.

Platelet activation is the primary cause of thrombosis. The P2X7 receptor (P2X7R) is a therapeutic target of thrombosis. However, it is still unknown whether P2X7R activation affects platelet thrombus. Our molecular docking results showed that entecavir as a P2X7R antagonist interacted perfectly with the human P2X7R (hP2X7R) in silico simulation studies. Furthermore, our experimental data revealed that entecavir could act as a P2X7R antagonist to exert cytoprotective effects against platelet activation via protecting mitochondrial function, improving lipid peroxidation and increasing antioxidant activity. Correlated with this, entecavir inhibited platelet aggregation, dense-granule secretion, P-selectin expression, integrin activation and Ca2+ increase. In experimental mouse model, entecavir could significantly inhibit arteriovenous thrombosis and prolong the bleeding time. Furthermore, we found that entecavir had no significant effect on prothrombin time (PT), activated partial thrombin time (APTT), thrombin time (TT), fibrinogen (FIB), mean platelet volume (MPV) and platelet counts (PLT). This study demonstrates that entecavir markedly prevents platelet activation and thrombosis through inhibiting P2X7R without affecting coagulation system. Therefore, entecavir may be a potential candidate for treating thrombosis disease.

Dehydrocholic Acid Ameliorates Sodium Taurocholate-Induced Acute Biliary Pancreatitis in Mice.

Acute biliary pancreatitis (ABP) with a high mortality rate is an incurable digestive system disease induced by abnormal bile acid regurgitation due to the biliary obstruction. Dehydrocholic acid (DA) alleviates the severity of cholestatic hepatitis related to biliary inflammation, suggesting DA is potential to develop for the incurable ABP management. Here we identified DA potency and explored the underlying mechanism in ABP. Our data showed that DA administration not only reduced typically clinicopathological parameters including serum levels of amylase and lipase but also suppressed pancreatic tissue edema, necrosis and trypsin activation in ABP mice. We also found that DA significantly reduced the necrosis of pancreatic acinar cells induced by sodium taurocholate (NaT). Further experimental data showed the significant inhibitions of DA on mitochondrial membrane potential depolarization, ATP exhaustion, calcium overload and reactive oxygen species (ROS) erupted in acinar cells induced by NaT, indicating DA could avert acinar cell death through protecting the mitochondrial function, scavenging excessive oxidative stress and balancing calcium. The comprehensive study found DA elevated the expression of transcription factor EB (TFEB) in vitro thus to increase the functional lysosome content. Indeed, DA decreased the Microtubule-associated protein light chain 3 (LC3) II/I ratio as well as ubiquitin-binding protein p62 and Parkin expressions in vivo and in vitro, revealing autophagy restoration maybe through the improvement of TFEB-mediated lysosome biogenesis. These data indicate that DA improves ABP through the mitochondrial protection, antioxidant ability enhancement and autophagy recovery. In conclusion, our study proposes a potential therapy strategy for the incurable ABP.

[Methodology and applications for multimodal identification of active constituents of traditional Chinese medicine].

The discovery of active constituents of traditional Chinese medicine(TCM) faces multiple challenges, such as limited approaches to evaluate poly-pharmacological effects, and the lack of systematic methods to identify active constituents. Aimed at these bottleneck problems in the field, the present study intensively discussed the key scientific problems in the identification of active constituents of TCM, based on scientific methodologies including systematology, information theory, and synergetics. A comprehensive strategy is herein proposed to investigate the correlations between the chemical composition and biological activities of TCM, from macro-, meso-, and micro-scales. Moreover, in this study, we systematically proposed the methodology of the multimodal identification of TCM active constituents, and thoroughly constructed its core technologies. Its technical framework is suggested to be assessed by multimodal information acquisition, centered on multisource information fusion, and focused on interaction evaluation. Furthermore, the core technologies for the multimodal identification of active constituents of TCM were developed in this study, which is according to the characteristics of the exchanges of between TCM and biological organisms, in the aspects of material, energy and information. Finally, two examples of the application of the proposed method were briefly introduced. The proposed methodology provides a novel way to solve the bottlenecks in the study of active constituents of TCM, and lays the foundation for the multimodal study of TCM.

[Recent advances in treatment of viral pneumonia using Chinese patent medicine].

Viral pneumonia is caused by a spreading of lung infection caused by respiratory viruses. Some virus infections were found to be highly aggressive, leading to lung inflammation and severe damage in respiratory system with high fatality rate. Currently, there is no effective therapeutic drugs in the clinic. The common clinical symptoms of viral pneumonias include fever, rhinitis, runny nose, nonproductive cough, fatigue, myalgias and headaches after the immune system being tricked by driving cytokines and overactivated immune response induced by cytokine storms. Patients with severe symptoms could get persistent high fever, dysfunctional breathing, consciousness disorders and even respiratory failure, post-inflammatory pulmonary fibrosis, multi-organ damages, shock and so on. Most clinical treatments are used to inhibit virus replication, relieve symptoms, inhibit excessive inflammatory response, regulate immune balance and protect organs. Both applied and basic research demonstrate that Chinese patent medicine has certain anti-viral effects, effectively inhibiting viral pneumonia transiting from mild to severe, rapid relieving of patient symptoms because of their multi-component and multi-target integrated roles. This review has summarized the reports on the treatment of viral pneumonia. Based on the pathogenic characteristics of viral pneumonia, this paper summarizes the diverse roles of the marketed Chinese patent medicine, such as their effects in inhibiting the progress of viral replication and overactivated inflammatory response, regulating immune balance, attenuating pulmonary fibrosis and so forth. Our paper summarizes the advantages of Chinese patient medicine in the treatment of viral pneumonia, based on which improvements of clinical therapy are expected to be made soon.

[Mechanism of Xuanfei Baidu Tang in treatment of COVID-19 based on network pharmacology].

The study aimed to investigate the multi-constituent, multi-target mechanism of Xuanfei Baidu Tang(XFBD) in the treatment of coronavirus disease 2019(COVID-19), through exploring the main ingredients and effective targets of XFBD, as well as analyzing the correlation between XFBD targets and COVID-19. The compounds of each herb in XFBD were collected from TCM-PTD, ETCM, TCMSP and SymMap database. Next, the information of meridian tropisms was collected from Chinese Pharmacopoeia(2015 edition), and the target information of the major constituents of XFBD were obtained from TCM-PTD, ETCM, TCMSP and TargetNet database. Subsequently, the target network model and the major modules were generated by Cytoscape, and the functional enrichment analysis of XFBD targets were completed by DAVID and STRING. As a result, ten of the 13 herbs in XFBD belonged to the lung meridian, and 326 of the 1 224 putative XFBD targets were associated with the disease target of COVID-19, among which 109 targets were enriched in the disease pathways of viral infection and lung injury. The main biological pathways regulated by the key XFBD targets included viral infection, energy metabolism, immunity and inflammation, parasites and bacterial infections. In conclusion, the therapeutic mechanism of XFBD in COVID-19 showed a multi-herb, multi-constituent, multi-target pattern, with lung as the chief targeted organ. By regulating a series of biological pathways closely related to the occurrence and development of diseases, XFBD plays a role in balancing immunity, eliminating inflammation, regulating hepatic and biliary metabolism and recovering energy metabolism balance.
