JOURNAL OF ETHNOPHARMACOLOGY 2024; 325:117862. [PMID: 38342157 DOI: 10.1016/j.jep.2024.117862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/17/2024] [Accepted: 02/02/2024] [Indexed: 02/13/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The herb pair of Chuanxiong Rhizome (Ligusticum chuanxiong Hort., Chuanxiong in Chinese, CX) and Paeoniae Radix Rubra (Paeonia lactiflora Pall. Or Paeonia veitchii Lynch, Chishao in Chinese, CS) is a famous blood activating and stasis resolving pair that is often found in traditional Chinese medicine (TCM) formulas for the treatment of acute lung injury (ALI). However, the relationship of CX-CS herb pair to ALI and its underlying mechanisms are unclear. AIM OF THE STUDY The study explored the effect and mechanisms of CX-CS herb pair in LPS induced ALI by network pharmacology and molecular docking combined with preclinical evaluation. MATERIALS AND METHODS The related targets of the active compounds of CX-CS herb pair in regulating ALI were screened by network pharmacology. PPI was constructed and the potential pathways were investigated by GO and KEGG. The contribution of each active ingredient of CX-CS herb pair to ALI were calculated by network-based efficacy. The interactions between potential targets and active ingredients were evaluated by molecular docking. LPS stimulated RAW264.7 cells and mice model experiments were adopted to verify the effect of CX-CS herb pair on ALI. RESULTS A total of 25 compounds and 193 targets were identified in the CX-CS herb pair, of which 19 compounds and 64 targets were associated with ALI, and six compounds including baicalin, ellagic acid, baicalein, beta-sitosterol, paeoniflorin and ferulic acid accounted for 93.12% of the total combination index for ALI prevention. The CX-CS herbal pair against ALI was associated with PI3K/AKT and MAPK signaling pathways by GO and KEGG analysis. The screened active compounds showed good affinity for TNF, MAPK, and AKT by molecular docking. In vitro and in vivo tests showed that CX combined with CS synergistically inhibited LPS-induced ALI at 1:3, suppressed the release of TNF-α, IL-1β and IL-6, inhibited the accumulation of ROS, as well as regulated the content of SOD, MDA and GSH. Meanwhile, the herb pair was effective in inhibiting the expression of p38, ERK, IκBα, p65, caspase 3, PARP, and up-regulating the levels of AKT and Bcl-2/Bax. CONCLUSIONS Our study confirmed the synergistic effect of CX-CS herb pair on the prevention of ALI by inhibiting inflammation, oxidative stress, and apoptosis through MAPK/NF-κB and PI3K/AKT signaling pathways.

Abstract
BACKGROUND Xuebijing (XBJ) is widely applied in the treatment of Acute Lung Injury (ALI). This study focused on the potential mechanism of XBJ in Lipopolysaccharide (LPS)-induced ALI. METHODS The rat ALI model was established by injection of LPS (10 mg/kg) and pretreated with XBJ (4 mL/kg) three days before LPS injection. BEAS-2B cell line was stimulated with LPS (1 μg/mL) and ATP (5 mM) to induce pyroptosis, and XBJ (2 g/L) was pretreated 24h before induction. The improvement effects of XBJ on pulmonary edema, morphological changes, and apoptosis in ALI lung tissue were evaluated by lung wet/dry weight ratio, HE-staining, and TUNEL staining. Inflammatory cytokines in lung tissue and cell supernatant were determined by ELISA. pyroptosis was detected by flow cytometry. Meanwhile, the expressions of miR-181d-5p, SPP1, p-p65, NLRP3, ASC, caspase-1, p20, and GSDMD-N in tissues and cells were assessed by RT-qPCR and immunoblotting. The relationship between miR-181d-5p and SPP1 in experimental inflammation was reported by dual luciferase assay. RESULTS XBJ could improve inflammation and pyroptosis of ALI by inhibiting contents of inflammatory cytokines, and levels of inflammation- and pyroptosis-related proteins. Mechanistically, XBJ could up-regulate miR-181d-5p and inhibit SPP1 in ALI. miR-181d-5p can target the regulation of SPP1. Depressing miR-181d-5p compensated for the ameliorative effect of XBJ on ALI, and overexpressing SPP1 suppressed the attenuating effect of XBJ on LPS-induced inflammation and pyroptosis. CONCLUSION XBJ can regulate the miR-181d-5p/SPP1 axis to improve inflammatory response and pyroptosis in ALI.

Abstract
Liang-Ge (LG) decoction could ameliorate coagulation dysfunction in septic model rats. However, the mechanism of LG in treating sepsis still needs to be clarified. Our current study established a septic rat model to evaluate the effect of LG on coagulation dysfunction in septic rats first. Second, we investigated the effect of LG on NET formation in septic rats. Finally, NETs and PAD4 inhibitors were further used to clarify if LG could improve the mechanism of sepsis coagulation dysfunction by inhibiting NET formation. Our findings indicated that treatment with LG improved the survival rate, reduced inflammatory factor levels, enhanced hepatic and renal function, and reduced pathological changes in rats with sepsis. LG could also alleviate coagulation dysfunction in septic model rats. Besides, LG treatment reduced NETs formation and decreased PAD4 expression in neutrophiles. In addition, LG treatment showed a similar result in comparison to the treatment with either NET inhibitors or PAD4 inhibitors alone. In conclusion, this study confirmed that LG has therapeutic effects on septic rats. Furthermore, the improvement of coagulation dysfunction in septic rats by LG was achieved through inhibiting PAD4-mediated NET formation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xuebijing injection is a Chinese herbal-derived drug composed of radix paeoniaerubra, rhizomachuanxiong, Salvia miltiorrhiza, floscarthami, and Angelica sinensis. This study aimed to investigate the effects of Xuebijing administration on pulmonary endothelial injury and coagulation dysfunction in a cecal ligation and puncture (CLP)-induced sepsis rat model. MATERIALS AND METHODS A CLP-induced sepsis rat model was established. The CLP rats were treated with a vehicle or Xuebijing via intravenous infusion and sacrificed at 2, 4, 6, 8, or 12 h after CLP for lung tissue and blood sample collection. The mean arterial pressure (MAP) was monitored. Transmission microscopy examination and H&E staining were performed to observe pulmonary structural alterations. Enzyme linked immunosorbent assay (ELISA) was performed to measure the plasma levels of epithelial markers, proinflammatory cytokines, and coagulation-related proteins. RESULTS Compared with vehicle treatment, Xuebijing administration maintained the MAP in the normal range until 11 h after CLP. Transmission microscopy and H&E staining revealed that Xuebijing administration alleviated alveolar-capillary barrier impairments and lung inflammation in CLP rats. ELISA showed that Xuebijing administration effectively reversed CLP-induced elevations in the plasma levels of epithelial markers endothelin-1 and von Willebrand factor, starting 6 and 8 h after CLP, respectively. Xuebijing administration also significantly abolished CLP-induced rises in circulating proinflammatory cytokines interleukin 6 (IL-6) at 6 h after CLP, IL-1β at 2 and 12 h after CLP, and TNF-α at 2, 4, 6, 8, and 12 h after CLP. In addition, Xuebijing administration strongly reversed CLP-induced alterations in circulating active protein C and tissue-type plasminogen activator, starting 4 h and 2 h after CLP, respectively. CONCLUSIONS Xuebijing ameliorates pulmonary endothelial injury, systemic inflammation, and coagulation dysfunction in early sepsis.

Abstract
Acute respiratory distress syndrome (ARDS) is a common critical illness in respiratory care units with a huge public health burden. Despite tremendous advances in the prevention and treatment of ARDS, it remains the main cause of intensive care unit (ICU) management, and the mortality rate of ARDS remains unacceptably high. The poor performance of ARDS is closely related to its heterogeneous clinical syndrome caused by complicated pathophysiology. Based on the different pathophysiology phases, drugs, protective mechanical ventilation, conservative fluid therapy, and other treatment have been developed to serve as the ARDS therapeutic methods. In recent years, there has been a rapid development in nanomedicine, in which nanoparticles as drug delivery vehicles have been extensively studied in the treatment of ARDS. This study provides an overview of pharmacologic therapies for ARDS, including conventional drugs, natural medicine therapy, and nanomedicine. Particularly, we discuss the unique mechanism and strength of nanomedicine which may provide great promises in treating ARDS in the future.

Abstract
Liang-Ge decoction (LG) has been used in the treatment of early stage of spesis and can ameliorate sepsis-associated lung injury. However, the mechanism of LG on sepsis-associated lung injury remains unknown. In this study, we established a rat model of sepsis-associated lung injury using the cecal ligation and puncture (CLP) method, and investigated the therapeutic effects of LG on lung injury in rats with sepsis. In addition, the anti-inflammatory, anti-oxidative and anti-apoptotic effects of LG on sepsis-associated lung injury model rats were evaluated. Besides, untargeted metabolomics was used to investigate the regulation of metabolites in rats with sepsis-associated lung injury after LG treatment. Our results showed that LG could decrease the wet/dry (W/D) ratio in lung and the total cell count and total protein concentration in bronchoalveolar lavage fluid (BALF) in septic model rats. Hematoxylin and eosin (HE) staining showed that LG reduced the infiltration of pro-inflammatory cells in lung. In addition, LG treatmment down-regulated the gene and protein expression of pro-inflammatory cytokins in lung tissue and BALF. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were increased and the level of methane dicarboxylic aldehyde (MDA) was decreased in lung tissue homogenate in septic model rats after LG treament. Moreover, the numbers of apoptotic cells in lung were reduced and the activity of lactic dehydrogenase (LDH) in BALF was decreased in septic model rats after LG treament. Untargeted metabolomics analysis showed that LG treatment affected the levels of 23 metabolites in lung in septic model rats such as citric acid, methionine, threonine, alpha-ketoglutaric acid, and inositol, these metabolites were associated with the glycine, serine and threonine metabolism, cysteine and methionine metabolism, inositol phosphate metabolism and citrate cycle (TCA cycle) pathways. In conclusion, our study demonstrated the therapeutic effetcts of LG on sepsis-associated lung injury model rats. Moreover, LG could inhibit the inflammatory response, oxidative stress, apoptosis and regulate metabolites related to glycine, serine and threonine metabolism, cysteine and methionine metabolism, inositol phosphate metabolism and TCA cycle in lung in sepsis-associated lung injury model rats.

The Renshen Chishao Decoction Could Ameliorate the Acute Lung Injury but Could Not Reduce the Neutrophil Extracellular Traps Formation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:7784148. [PMID: 36072401 PMCID: PMC9444383 DOI: 10.1155/2022/7784148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 04/18/2022] [Accepted: 08/01/2022] [Indexed: 11/25/2022]
Abstract
The acute lung injury (ALI) causes severe pulmonary diseases, leading to a high mortality rate. The Renshen and Chishao have protective and anti-inflammatory effects against the ALI. To explore the protective effects of the Renshen Chishao (RC) decoction against the ALI, we established the lipopolysaccharide-indued ALI model and randomly divided the mice into seven groups: control group, ALI group, high-dose RC group, middle-dose RC group, low-dose RC group, middle-dose RC group + CXCR2 antagonist group, and ALI + CXCR2 antagonist group. We estimated the lung injury by the hematoxylin and eosin staining, the neutrophil extracellular traps (NETs) formations by the immunofluorescence colocalization and enzyme-linked immunosorbent assay (ELISA), and the CXCR2/CXCL2 pathway by the flow cytometry, ELISA, and real-time polymerase chain reaction. We conducted the high-throughput sequencing and enrichment analyses to explore the potential mechanisms. The results showed that the RC decoction pathologically ameliorated the lipopolysaccharide-induced lung injury and inflammatory response but failed to reduce the circulating and lung tissue NETs formation and the blood neutrophil percent. The high-dose RC decoction increased the plasma CXCL2 level, but the RC decoction had no effects on the neutrophilic CXCR2 levels. Under the inhibition of the CXCR2, the middle-dose RC decoction still decreased the lung injury score but as yet had unobvious influence on the NETs formation. Other potential mechanisms of the RC decoction against the ALI involved the pathways of ribosome and coronavirus disease 2019 (COVID-19); the target genes of inflammatory factors, such as Ccl17, Cxcl17, Cd163, Cxcr5, and Il31ra, and lncRNAs; and the regulations of the respiratory cilia. In conclusion, the RC decoction pathologically ameliorated the lipopolysaccharide-induced lung inflammatory injury via upregulating the CXCL2/CXCR2 pathway but could not reduce the circulating or lung tissue NETs formation.

Abstract
Lung epithelium is constantly exposed to the environment and is critically important for the orchestration of initial responses to infectious organisms, toxins, and allergic stimuli, and maintenance of normal gaseous exchange and pulmonary function. The integrity of lung epithelium, fluid balance, and transport of molecules is dictated by the tight junctions (TJs). The TJs are formed between adjacent cells. We have focused on the topic of the TJ structure and function in lung epithelial cells. This review includes a summary of the last twenty years of literature reports published on the disrupted TJs and epithelial barrier in various lung conditions and expression and regulation of specific TJ proteins against pathogenic stimuli. We discuss the molecular signaling and crosstalk among signaling pathways that control the TJ structure and function. The Toll-like receptor-4 (TLR4) recognizes the pathogen- and damage-associated molecular patterns released during lung injury and inflammation and coordinates cellular responses. The molecular aspects of TLR4 signaling in the context of TJs or the epithelial barrier are not fully known. We describe the current knowledge and possible networking of the TLR4-signaling with cellular and molecular mechanisms of TJs, lung epithelial barrier function, and resistance to treatment strategies.

Abstract
A case-control study was conducted to evaluate the efficacy of continuous veno-venous hemofiltration (CVVH) combined with Xuebijing in the treatment of severe sepsis. In order to verify this claim, this study included 100 patients with severe sepsis treated in our hospital from February 2019 to April 2021. The patients were randomly divided into control group and study group. The control group was treated with CVVH, and the study group was treated with CVVH combined with Xuebijing. The curative effect and mortality, NT-proBNP, PCT, Ca∼_(2+), white blood cell count, neutrophil ratio, blood gas analysis, and APACHE-II score were compared between the two groups. The total effective rate of the study group was better than that of the control group (P < 0.05). The fatality rate in the study group was lower than that in the control group (P < 0.05). The levels of NT-proBNP and PCT in the study group were lower than those in the control group, while the level of serum calcium in the study group was higher than that in the control group. After treatment, the white blood cell count (WBC) and neutrophil count in the study group were (13.76 ± 1.28) × 109 shock L and (73.48 ± 1.23)%, respectively, which were significantly lower than those in the control group (17.45 ± 1.36) × 109 shock L and (77.82 ± 1.44)% (P < 0.05). After treatment, the levels of APTT, PT, and DD in the study group were lower than those in the control group. The level of FIB in the study group was significantly higher than that in the control group after treatment. After treatment, the PaO2 and PaO2/FiO2 of the study group were higher than those of the control group, and the APACHE-II score of the study group was lower than that of the control group. CVVH combined with Xuebijing is of positive significance in the treatment of severe sepsis and is worth popularizing.

Notoginsenoside R1 (NG-R1), the extract and the main ingredient of Panax notoginseng, has anti-inflammatory effects and can be used in treating acute lung injury (ALI). In this study, we explored the pulmonary protective effect and the underlying mechanism of the NG-R1 on rats with ALI induced by severe acute pancreatitis (SAP). MiR-128-2-5p, ERK1, Tollip, HMGB1, TLR4, IκB, and NF-κB mRNA expression levels were measured using real-time qPCR, and TLR4, Tollip, HMGB1, IRAK1, MyD88, ERK1, NF-κB65, and P-IκB-α protein expression levels using Western blot. The NF-κB and the TLR4 activities were determined using immunohistochemistry, and TNF-α, IL-6, IL-1β, and ICAM-1 levels in the bronchoalveolar lavage fluid (BALF) using ELISA. Lung histopathological changes were observed in each group. NG-R1 treatment reduced miR-128-2-5p expression in the lung tissue, increased Tollip expression, inhibited HMGB1, TLR4, TRAF6, IRAK1, MyD88, NF-κB65, and p-IκB-α expression levels, suppressed NF-κB65 and the TLR4 expression levels, reduced MPO activity, reduced TNF-α, IL-1β, IL-6, and ICAM-1 levels in BALF, and alleviated SAP-induced ALI. NG-R1 can attenuate SAP-induced ALI. The mechanism of action may be due to a decreased expression of miR-128-2-5p, increased activity of the Tollip signaling pathway, decreased activity of HMGB1/TLR4 and ERK1 signaling pathways, and decreased inflammatory response to SAP-induced ALI. Tollip was the regulatory target of miR-128-2-5p.

Abstract
COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across the globe, posing an enormous threat to public health and safety. Traditional Chinese medicine (TCM), in combination with Western medicine (WM), has made important and lasting contributions in the battle against COVID-19. In this review, updated clinical effects and potential mechanisms of TCM, presented in newly recognized three distinct phases of the disease, are summarized and discussed. By integrating the available clinical and preclinical evidence, the efficacies and underlying mechanisms of TCM on COVID-19, including the highly recommended three Chinese patent medicines and three Chinese medicine formulas, are described in a panorama. We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19, but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.

Abstract
Background Radiation pneumonia (RP) is the most common complication of radiotherapy to the thorax and seriously affects the survival rate and quality of life of patients. Radix Salviae Miltiorrhizae (RSM) is an ancient Chinese medicine, whose main pharmacological effect is to promote blood circulation and remove stasis. A growing number of studies have proved that RSM has a good effect on RP. However, the underlying mechanism is still unclear and needs to be fully elucidated. Methods The effective components and predictive targets of RSM were analyzed by Traditional Chinese Medicine Systems Pharmacology (TCMSP) database, and the related targets of RP were predicted by GeneCards database. The common targets of the two targets mentioned above were analyzed by protein-protein interaction on the STRING website, GO and KEGG analysis on the DAVID website, visualization by CytoScape3.7.0, and screening for Hubber gene by cytoHubber plug-in. Results A search of the TCMSP database revealed that RSM contains 65 chemical constituents and 165 potential protein targets. A total of 2,162 protein targets were found to be associated with RP. The top 10 hub genes were obtained by MCC algorithm for 70 common genes, including TP53, CASP3, MAPK1, JUN, VEGFA, STAT3, PTGS2, IL6, AKT1, and FOS. By analyzing the Gene Ontology, The anti-radiation pneumonia effect of RSM is that it performs molecular functions (protein homodimerization activity) in the nucleus through three biological processes (positive regulation of transcription from RNA polymerase II promoter,Extrinsic apoptotic signaling pathway in absence of ligand and lipopolysaccharide-mediated signaling pathway). Through KEGG analysis, the mechanism of RSM treatment of radiation pneumonia may be through PI3K-Akt, HIF-1, TNF signaling pathways. Conclusions Through network pharmacology analysis, we found the possible target genes of RSM on RP and revealed the most likely signaling pathway, providing theoretical basis for further elucidating the potential mechanism of RSM on RP.

Overexpression of TOLLIP Protects against Acute Kidney Injury after Paraquat Intoxication through Inhibiting NLRP3 Inflammasome Activation Modulated by Toll-Like Receptor 2/4 Signaling. Mediators Inflamm 2021; 2021:5571272. [PMID: 34335089 PMCID: PMC8298172 DOI: 10.1155/2021/5571272] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 05/10/2021] [Accepted: 06/09/2021] [Indexed: 01/22/2023] Open
Abstract
Paraquat (PQ) can cause multiorgan failure including acute kidney injury (AKI). Our prior study showed that Toll-interacting protein (TOLLIP) protected against PQ-induced acute lung injury. However, the role of TOLLIP in PQ-induced AKI remains undefined. This study was aimed at understanding the role and mechanism of TOLLIP in AKI. Six-eight-week-old male Wistar rats were intraperitoneally injected with 25 mg/kg PQ to induce AKI for 24 h in vivo. HK-2 cells were treated with 300 μM PQ for 24 h to induce cellular injury in vitro or 300 μM PQ and 5 μM nuclear factor-κB (NF-κB) inhibitor BAY11-7082 for 24 h. Rats were infected with adenovirus carrying TOLLIP shRNA via tail vein injection and HK-2 cells with adenovirus carrying TOLLIP shRNA or TOLLIP 48 h before PQ exposure. Results showed that TOLLIP and Toll-like receptor 2/4 (TLR2/4) expressions were boosted in the kidney after PQ intoxication. The toxic effect of PQ on the kidney and HK-2 cells was exacerbated by TOLLIP knockdown, as evidenced by aggravated glomerulus and tubule injury, inflammatory infiltration, and cell apoptosis in the kidney and increased loss of cell viability and apoptotic cells in HK-2 cells. TOLLIP knockdown also enhanced PQ-induced NLR family pyrin domain-containing 3 (NLRP3) inflammasome activation in vivo and in vitro and TLR2/4-NF-κB signaling in vitro, reflected by increased contents of proinflammatory cytokines and expressions of NLRP3 inflammasome-related proteins in the kidney and HK-2 cells and expressions of TLR2, TLR4, and nuclear NF-κB p65 in HK-2 cells. However, TOLLIP overexpression inhibited PQ-induced loss of cell viability, cell apoptosis, NLRP3 inflammasome activation, and TLR2/4-NF-κB signaling in vitro. Additionally, BAY11-7082 abolished TOLLIP knockdown-induced NLRP3 inflammasome activation in vitro, indicating that TOLLIP protected against NLRP3 inflammasome activation in PQ-induced AKI through inhibiting TLR2/4-NF-κB signaling. This study highlights the importance of TOLLIP in AKI after PQ intoxication.

OBJECTIVES This study hypothesized that to analyse the anti-inflammatory effect of triterpenoid compound betulin in ovalbumin (OVA)-induced asthmatic mice. METHODS In this study, betulin was intraperitoneally administered in OVA-challenged and sensitized mice. The effect of betulin on inflammatory cells, lung function, reactive oxygen species (ROS) production, antioxidants status, oxidative stress markers, serum IgE level and inflammatory cytokines status in BALF was examined by enzyme-linked immunosorbent assay. The expression of tTG, TGF-β1, MMP-9 and TIMP-1 in lung tissue was scrutinized by RT-qPCR analysis, and the expression of TREM-1, p-IκB-α and NF-κBp65 proteins in lung tissue was examined by western blot analysis. KEY FINDINGS We found that the betulin treatment has effectively attenuated the proliferation of inflammatory cells, reduced the ROS generation, elevated the antioxidant enzymes and attenuated the level of oxidative markers in asthma induced mice. Moreover, reduced the level of serum IgE and pro-inflammatory cytokines, and increased the anti-inflammatory cytokine IFN-γ. Betulin treatment down-regulated the expression of MMP-9, tTG and TGF-β1 genes; moreover, betulin treatment effectively down-regulated the TREM-1, p-IκB-α and NF-κBp65 proteins level in lung. CONCLUSION Betulin exhibited effective anti-asthmatic activity by attenuating the accumulation of inflammatory cells, expression of tTG, TGF-β1 and MMP-9 genes in lung tissue.

Abstract
Introduction COVID-19 is severely affecting countries globally and mortality is high. Xuebijing (XBJ) injection is widely used in the treatment of severe pneumonia and sepsis in China due to its anti-inflammatory effect and immunoregulation. This study investigated whether Xuebijing injection can prevent the cytokine storm and reduce the mortality from severe COVID-19. Methods This was a randomized, double-blinded trial in which 60 eligible patients were recruited from the First people's Hospital of Jingzhou from February 16 to March 25 in 2020. A total of 57 completed the trial, 3 dropped out. The treatment group received routine medication plus Xuebijing injection while the control group received routine medication plus saline. Results The secretion of interleukin-6(IL-6), interleukin-8(IL-8) and tumor necrosis factor-α(TNF-α) was suppressed significantly (P < 0.05) by Xuebijing. After 14 days treatment, lymphocyte levels in Xuebijing group was substantially higher than control, C-reactive protein (CRP) level in Xuebijing group was remarkably lower. The 28-day mortality was not significantly different between the two group. After 14 days of treatment, there were significant differences in the rate of mechanical ventilation, rate of septic shock, the proportion of patients severely affected who became critically ill, the duration of improvement of main clinical symptoms (P < 0.05) and the length of ICU hospitalization stay (P < 0.01) for the Xuebijing group compared with controls. No serious adverse reactions were identified in either group. Conclusions This study demonstrates that Xuebijing injection may suppress the cytokine storm in severe COVID-19 patients by regulating the secretion of pro- inflammatory cytokine IL-6, IL-8 and TNF -α. However, Xuebijing did not significantly reduce the 28-day mortality.

Respir Physiol Neurobiol 2020; 286:103600.

Abstract
Toll-interacting protein (Tollip) is a pivotal negative regulator of inflammatory response. In the present study, the effects of Tollip overexpression on paraquat (PQ)-induced lung injury were explored through in vivo and in vitro investigations. Upon stimulation with PQ in mice, the expression of Tollip was down-regulated. Histopathological analysis revealed that the overexpression of Tollip significantly decreased inflammatory cell infiltration. Similarly, the levels of myeloperoxidase (MPO) and interleukin-1β (IL-1β) were lowered by Tollip overexpression in PQ-administrated mice. Besides, the overexpression of Tollip reduced reactive oxygen species (ROS) generation and malondialdehyde (MDA) level but enhanced superoxide dismutase (SOD) activity in PQ-treated A549 cells. Meanwhile, Tollip overexpression lowered the level of IL-1β and decreased the protein expressions of p-p65 in the cytoplasm and nuclear p65. Importantly, inhibition of NF-κB signaling pathway probably by decreasing NF-κB p65-DNA binding activity was induced by Tollip overexpression. Taken together, Tollip overexpression attenuated PQ-initiated lung injury possibly via reduction of oxidative stress and inflammation and suppression of NF-κB signaling pathway activation, which provided some novel ideas for the treatment of lung damage mediated by PQ.

Abstract
Background There were few studies on the case mortality of severe community-acquired pneumonia (CAP) in elderly people. Improved outcomes with XueBiJing (XBJ) injection vs placebo have been shown in overall trial populations. We investigated the efficacy and safety of XBJ vs placebo in subjects with severe CAP stratified by age (<65 and ≥65 years). Methods This post hoc analysis of a large randomized trial compared data from elderly and nonelderly patients with XBJ, 100 mL, q 12 h, or a visually indistinguishable placebo for five-to-seven days. Results Among subjects ≥65 years (n=291), 23 (16.0%) XBJ recipients and 41 (27.9%) placebo recipients (P=0.014) died within 28 days. Among subjects <65 years (n=360), XBJ still had lower mortality (XBJ 15.6% vs placebo 22.8%; P=0.082), without significantly statistical difference. Total duration of ICU stay and the time of mechanical ventilation were similar in both groups (P>0.05). XBJ also had a favorable safety profile, with no clinically relevant differences between the two groups. The overall incidence of adverse events was similar in both groups. Conclusion XBJ was safe and effective for reduction in 28-day mortality among elderly patients with severe CAP. Additional confirmatory trials involving elderly patients are needed to further confirm the present results. Trial Registration http://www.chictr.org.cn/index.aspx. ChiCTR-TRC-13003534.

Abstract
Background Chinese medicine Xuebijing (XBJ) has proven to be effective in the treatment of mild coronavirus disease 2019 (COVID-19) cases. But the bioactive compounds and potential mechanisms of XBJ for COVID-19 prevention and treatment are unclear. This study aimed to examine the potential effector mechanisms of XBJ on COVID-19 based on network pharmacology. Methods We searched Chinese and international papers to obtain the active ingredients of XBJ. Then, we compiled COVID-19 disease targets from the GeneCards gene database and via literature searches. Next, we used the SwissTargetPrediction database to predict XBJ’s effector targets and map them to the abovementioned COVID-19 disease targets in order to obtain potential therapeutic targets of XBJ. Cytoscape software version 3.7.0 was used to construct a “XBJ active-compound-potential-effector target” network and protein-protein interaction (PPI) network, and then to carry out network topology analysis of potential targets. We used the ClueGO and CluePedia plugins in Cytoscape to conduct gene ontology (GO) biological process (BP) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway enrichment analysis of XBJ’s effector targets. We used AutoDock vina and PyMOL software for molecular docking. Results We obtained 144 potential COVID-19 effector targets of XBJ. Fourteen of these targets-glyceraldehyde 3-phosphate dehydrogenase (GAPDH), albumin (ALB), tumor necrosis factor (TNF), epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 1 (MAPK1), Caspase-3 (CASP3), signal transducer and activator of transcription 3 (STAT3), MAPK8, prostaglandin-endoperoxide synthase 2 (PTGS2), JUN, interleukin-2 (IL-2), estrogen receptor 1 (ESR1), and MAPK14 had degree values > 40 and therefore could be considered key targets. They participated in extracellular signal–regulated kinase 1 and 2 (ERK1, ERK2) cascade, the T-cell receptor signaling pathway, activation of MAPK activity, cellular response to lipopolysaccharide, and other inflammation- and immune-related BPs. XBJ exerted its therapeutic effects through the renin-angiotensin system (RAS), nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB), MAPK, phosphatidylinositol-4, 5-bisphosphate 3-kinase (PI3K)-protein kinase B (Akt)-vascular endothelial growth factor (VEGF), toll-like receptor (TLR), TNF, and inflammatory-mediator regulation of transient receptor potential (TRP) signaling pathways to ultimately construct a “drug-ingredient-target-pathway” effector network. The molecular docking results showed that the core 18 effective ingredients had a docking score of less than − 4.0 with those top 10 targets. Conclusion The active ingredients of XBJ regulated different genes, acted on different pathways, and synergistically produced anti-inflammatory and immune-regulatory effects, which fully demonstrated the synergistic effects of different components on multiple targets and pathways. Our study demonstrated that key ingredients and their targets have potential binding activity, the existing studies on the pharmacological mechanisms of XBJ in the treatment of sepsis and severe pneumonia, could explain the effector mechanism of XBJ in COVID-19 treatment, and those provided a preliminary examination of the potential effector mechanism in this disease.

Kumar V. Toll-like receptors in sepsis-associated cytokine storm and their endogenous negative regulators as future immunomodulatory targets. Int Immunopharmacol 2020; 89:107087. [PMID: 33075714 PMCID: PMC7550173 DOI: 10.1016/j.intimp.2020.107087] [Citation(s) in RCA: 86] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2020] [Revised: 10/04/2020] [Accepted: 10/08/2020] [Indexed: 12/15/2022]
Abstract
Sepsis infects more than 48.9 million people world-wide, with 19.7 million deaths. Cytokine storm plays a significant role in sepsis, along with severe COVID-19. TLR signaling pathways plays a crucial role in generating the cytokine storm. Endogenous negative regulators of TLR signaling are crucial to regulate cytokine storm.
Cytokine storm generates during various systemic acute infections, including sepsis and current pandemic called COVID-19 (severe) causing devastating inflammatory conditions, which include multi-organ failure or multi-organ dysfunction syndrome (MODS) and death of the patient. Toll-like receptors (TLRs) are one of the major pattern recognition receptors (PRRs) expressed by immune cells as well as non-immune cells, including neurons, which play a crucial role in generating cytokine storm. They recognize microbial-associated molecular patterns (MAMPs, expressed by pathogens) and damage or death-associate molecular patterns (DAMPs; released and/expressed by damaged/killed host cells). Upon recognition of MAMPs and DAMPs, TLRs activate downstream signaling pathways releasing several pro-inflammatory mediators [cytokines, chemokines, interferons, and reactive oxygen and nitrogen species (ROS or RNS)], which cause acute inflammation meant to control the pathogen and repair the damage. Induction of an exaggerated response due to genetic makeup of the host and/or persistence of the pathogen due to its evasion mechanisms may lead to severe systemic inflammatory condition called sepsis in response to the generation of cytokine storm and organ dysfunction. The activation of TLR-induced inflammatory response is hardwired to the induction of several negative feedback mechanisms that come into play to conclude the response and maintain immune homeostasis. This state-of-the-art review describes the importance of TLR signaling in the onset of the sepsis-associated cytokine storm and discusses various host-derived endogenous negative regulators of TLR signaling pathways. The subject is very important as there is a vast array of genes and processes implicated in these negative feedback mechanisms. These molecules and mechanisms can be targeted for developing novel therapeutic drugs for cytokine storm-associated diseases, including sepsis, severe COVID-19, and other inflammatory diseases, where TLR-signaling plays a significant role.

Three Ingredients of Safflower Alleviate Acute Lung Injury and Inhibit NET Release Induced by Lipopolysaccharide. Mediators Inflamm 2020; 2020:2720369. [PMID: 32189992 PMCID: PMC7066412 DOI: 10.1155/2020/2720369] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 01/13/2020] [Accepted: 02/05/2020] [Indexed: 01/28/2023] Open
Abstract
Xuebijing injection is a Chinese herb compound to treat sepsis in China, but it contains many different kinds of components, and each component may have different effects in treating sepsis. The present study was performed to investigate the effect of three ingredients of Xuebijing, safflor yellow A (SYA), hydroxysafflor yellow A (HSYA), and anhydrosafflor yellow B (AHSYB), in lipopolysaccharide- (LPS-) induced acute lung injury (ALI). LPS (10 mg/kg) was injected intratracheally to induce acute lung injury in mice, which were then treated with SYA, HSYA, and AHSYB. The blood, bronchoalveolar lavage fluid (BALF), and lung tissues were collected to detect degree of lung injury, level of inflammation, and neutrophil extracellular traps (NETs). In vitro experiments were performed using HL-60 cells stimulated with phorbol myristate acetate (PMA). Lung injury induced by LPS was alleviated by SYA, HSYA, and AHSYB as demonstrated by the histopathologic test. The three components inhibit LPS-induced elevation of the levels of inflammatory factors and wet-to-dry weight ratio as well as the amount of protein and cells in the BALF. They also induced a remarkably less overlay of myeloperoxidase (MPO) and histone in the immunofluorescence assay and reduced level of MPO-DNA complex in plasma. The in vitro assay showed a similar trend that the three components inhibited PMA-induced NET release in neutrophil-like HL-60 cells. Western blot demonstrated that phosphorylation of c-rapidly accelerated fibrosarcoma (c-Raf), mitogen-activated protein kinase ERK kinase (MEK), and extracellular signal-regulated kinase (ERK) in the lungs of LPS-challenged mice, and PMA-treated HL-60 cells were all significantly reduced by SYA, HSYA, and AHSYB. Therefore, our data demonstrated that three components of XBJ, including SYA, HSYA, and AHSYB, showed a protective effect against LPS-induced lung injury and NET release.

Abstract
Xuebijing (XBJ) injection, a Chinese traditional medicine injection, is widely used in the treatment of sepsis in China, and shows a promising clinical therapeutic effect. However, its impacts on the metabolic changes of sepsis have not yet been reported. We established a septic rat model using cecal ligation and puncture (CLP) and treated with XBJ or placebo (saline). The survival rates were monitored for 7d, the effects of XBJ on liver and kidney tissue morphology, serum biochemistry [alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), and creatinine (Cr)] and cytokines [tumor necrosis factor-α (TNF-α) and interleukin 6 (IL-6)] production were assessed. Plasma samples were profiled by gas chromatography/mass spectrometer (GC/MS) and analyzed to evaluate the metabolites changes. We found that XBJ can increase the survival rate of septic rats by reducing multi-organ dysfunctions shown as decrease in serum biochemistry indicators, cytokines, and morphologic changes. A Partial Least-Squares Discriminant Analysis (PLS-DA) score plot indicated that rats undergo significant metabolic changes between the three groups. 21 distinct metabolites with VIP>1.5 and p<0.05 were were identified between these group. These metabolites primarily reflected disorders in energy metabolism, glucose metabolism and amino acid metabolism. This study established the foundation for further research of the mechanisms and therapeutic targets of sepsis.

Protective effects of Panax notoginseng saponins in a rat model of severe acute pancreatitis occur through regulation of inflammatory pathway signaling by upregulation of miR-181b. Int J Immunopathol Pharmacol 2018.

Abstract
Panax notoginseng saponins are extracted from Chinese
ginseng—Panax notoginseng Ledeb—and are known to have
therapeutic anti-inflammatory effects. However, the precise mechanism behind
their anti-inflammatory effects remains relatively unknown. To better understand
how Panax notoginseng saponins exert their therapeutic benefit,
we tested them in a rat model of severe acute pancreatitis (SAP). Rats received
a tail vein injection of Panax notoginseng saponins and were
administered 5% sodium taurocholate 2 h later. Pancreatic tissue was then
harvested and levels of miR-181b, FSTL1, TREM1, TLR4, TRAF6, IRAK1, p-Akt,
p-p38MAPK, NF-κBp65, and p-IκB-α were determined using Western blot and
quantitative real-time polymerase chain reaction (qRT-PCR). Enzyme-linked
immunosorbent assays were used to determine serum levels of tumor necrosis
factor-α (TNF-α), TREM1, interleukin (IL)-6, ACAM-1, IL-8, and IL-12 and
DNA-bound levels of NF-KB65 and TLR4 in pancreatic and ileum tissue. Serum
levels of lipase and amylase, pancreatic myeloperoxidase (MPO) activity, and
pancreatic water content were also measured. Hematoxylin and eosin staining was
used for all histological analyses. Results indicated upregulation of miR-181b,
but negligible levels of FSTL1, p-p38MAPK, TLR4, TRAF6, p-Akt, IRAK1, TREM1,
p-NF-κBp65, and p-IκB-α, as well as negligible DNA-bound levels of NF-KB65 and
TLR4. We also observed lower levels of IL-8, IL-6, ACAM-1, TNF-α, MPO, and IL-12
in the Panax notoginseng saponin–treated group when compared
with controls. In addition, Panax notoginseng saponin–treated
rats had significantly reduced serum levels of lipase and amylase. Histological
analyses confirmed that Panax notoginseng saponin treatment
significantly reduced taurocholate-induced pancreatic inflammation.
Collectively, our results suggest that Panax notoginseng
saponin treatment attenuated acute pancreatitis and pancreatic inflammation by
increasing miR-181b signaling. These findings suggest that Panax
notoginseng saponins have therapeutic potential in the treatment of
taurocholate-induced SAP.

Xuebijing injection induces anti-inflammatory-like effects and downregulates the expression of TLR4 and NF-κB in lung injury caused by dichlorvos poisoning. Biomed Pharmacother 2018; 106:1404-1411. [PMID: 30119213 DOI: 10.1016/j.biopha.2018.07.111] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Revised: 07/17/2018] [Accepted: 07/18/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The mechanism in lung injury caused by acute organophosphate pesticide poisoning (AOPP) and an effective treatment remains unclear. We aim to clarify how the inflammatory lung injury caused by AOPP might be modulated by Xuebijing (XBJ) injection. METHODS AOPP-induced lung injury model was induced by dichlorvos (DDVP) subcutaneous administration in rats and XBJ injection was administered by intraperitoneal injection after DDVP challenge. The effects of XBJ injection were assessed by lung histopathological analysis and lung injury scores, lung wet-to-dry weight ratios (WDR) and oxygenation, differential immune cell count in bronchoalveolar lavage fluid (BALF), IL-6 and TNF-α levels in blood, the levels of TLR4 and NF-κB proteins in lung tissue and blood acetylcholinesterase (AChE) activity. RESULTS DDVP administration resulted in damage of lung histopathology and lower PaO2/FiO2 ratios (P < 0.05), which were notably attenuated by XBJ injection (P < 0.05). Total cell, macrophage, and neutrophils count in BALF and TNF-α and IL-6 levels in blood were significantly increased after DDVP exposure (P < 0.05), which were notably ameliorated by XBJ injection (P < 0.05). TLR4 and NF-κB protein in lung tissue expression after DDVP challenge were markedly increased (P < 0.05), and they were substantially downregulated by XBJ injection (P < 0.05). In addition, blood AChE activity was significantly decreased by DDVP administration (P < 0.05), however, there was no significant improvement after XBJ injection. CONCLUSION XBJ injection prevents DDVP poisoning induced lung injury by attenuating the inflammatory response. The protective effect appears to be mediated through downregulation of the TLR4 and NF-κB expression.

Abstract
Alcohol (EtOH) dosage and exposure time can affect gene expression. However, whether there exists synergistic effect is unknown. Here, we analyzed the hDPSC gene microarray dataset GSE57255 downloaded from Gene Expression Omnibus and found that the interaction between EtOH dosage and exposure time on gene expression are statistically significant for two probes: 201917_s_at near gene SLC25A36 and 217649_at near gene ZFAND5. GeneMania showed that SLC25A36 and ZFAND5 were related to 20 genes, three of which had alcohol-related functions. WebGestalt revealed that the 22 genes were enriched in 10 KEGG pathways, four of which are related to alcoholic diseases. We explored the possible nonlinear interaction effect and got 172 gene probes with significant p-values. However, no significantly enriched pathways based on the 172 probes were detected. Our analyses indicated a possible molecular mechanism that could help explain why alcohol consumption has both deleterious and beneficial effects on human health.

Abstract
Airway remodeling in asthma contributes to airway hyperreactivity, loss of lung function and persistent symptoms. Current therapies do not adequately treat the structural airway changes associated with asthma. Statin drugs have improved respiratory health and their therapeutic potential in asthma has been tested in clinical trials. However, the mechanism of action of statins in this context has remained elusive. The present study hypothesized that atorvastatin treatment of ovalbumin-exposed mice attenuates early features of airway remodeling via a mevalonate-dependent mechanism. BALB/c mice were sensitized with ovalbumin and atorvastatin was delivered via oral gavage prior to each ovalbumin exposure. Reverse transcription-semi-quantitative polymerase chain reaction (RT-semi-qPCR), ELISA and western blot analysis were used to assess the expression of a number of relevant genes, including tissue transglutaminase (tTG), triggering receptor expressed on myeloid cells (TREM)-1, nuclear factor erythroid 2-related factor (Nrf) 2, hypoxia-inducible factor (HIF)-1α, transforming growth factor (TGF)-β1, matrix metalloproteinase (MMP)-9 and tissue inhibitors of metalloproteinases (TIMP)-1 in lung tissue. α-Smooth muscle actin (α-SMA) activity was measured by immunohistochemistry. Airway hyperresponsiveness, lung collagen deposition, airway wall area, airway smooth muscle thickness and lung pathology were also assessed. Atorvastatin treatment led to downregulation of tTG and TREM-1 expression in lung tissue after ovalbumin sensitization, blocked the activity of MMP-9, vascular endothelial growth factor, nuclear factor-κB p65, α-SMA, HIF-α and TGF-β1 and up-regulated Nrf2 expression. Furthermore, the number of lymphocytes and eosinophils in the atorvastatin group was significantly lower than that in the control group. In addition, airway hyperresponsiveness, lung collagen deposition, airway wall area, airway smooth muscle thickness and pathological changes in the lung were significantly decreased in the atorvastatin group, and tumor necrosis factor-α, interleukin (IL)-8, IL-13 and IL-17 in serum were significantly decreased. Histological results demonstrated the attenuating effect of atorvastatin on ovalbumin-induced airway remodeling in asthma. In conclusion, the present study indicated that atorvastatin significantly alleviated ovalbumin-induced airway remodeling in asthma by downregulating tTG and TREM-1 expression. The marked protective effects of atorvastatin suggest its therapeutic potential in ovalbumin-induced airway remodeling in asthma treatment.

Abstract
OBJECTIVE To investigate the effect of combined application of Xuebijing Injection ( , XBJ) and resolvin D1 (RvD1) on survival rate and the underlying mechanisms in mice with sepsisinduced lung injury. METHODS The cecal ligation and puncture (CLP) method was used to develop a mouse sepsis model. Specific pathogen free male C57BL/6 mice were randomly divided into 5 groups (n=20 each): sham, CLP, CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1. After surgery, mice in the CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1 groups were given XBJ (25 μL/g body weight), RvD1 (10 ng/g body weight), and their combination (the same dose of XBJ and RvD1), respectively. In each group, 12 mice were used to observe 1-week survival rate, while the rest were executed at 12 h. Whole blood was collected for flow cytometric analysis of leukocyte adhesion molecules CD18, lung tissues were harvested for observing pathological changes, and testing the activity of myeloperoxidase (MPO) and the expression of intercellular cell adhesion molecule 1 (ICAM-1). RESULTS Compared with the CLP group, the histopathological damage of the lung tissues was mitigated, MPO activity was decreased in the CLP+XBJ and CLP+RvD1 groups (P<0.05). In addition, the 1-week survival rate was improved, proportion of CD18-expressing cells in whole blood and ICAM-1 protein expression in lung tissue were decreased in the CLP+XBJ+RvD1 group (P<0.05 or P<0.01). CONCLUSIONS XBJ together with RvD1 could effectively inhibit leukocyte adhesion, reduce lung injury, and improve the survival rate of mice with sepsis.

Abstract
OBJECTIVE High vasopermeability and excessive inflammation following severe burns may result in tissue edema, organ dysfunction and the loss of circulatory plasma volume, which can influence the doctor to do the prognosis to the patients. The study aims to examine whether Xuebijing injection (XBJ), an extracts of a traditional Chinese medicine used to treat sepsis in clinic, can reduces fluid requirements by inhibiting vasopermeability and tissue edema in a canine model after burn injury. METHODS Twenty-four beagle dogs were subjected to 50% TBSA burns, and then were randomly allocated to the following three groups: lactated Ringer's resuscitation (LR) group (n = 8), immediate LR containing Xuebijing injection (LR/XBJ) group (n = 8), and operation control group (n = 8). Hemodynamic variables and net fluid accumulation were measured. Blood samples were collected for measurement of hematocrit and circulatory plasma volume (PV). At 24 h after burn injury, heart, lung, small intestine and kidney were harvested for evaluation of the activities of myeloperoxidase (MPO) and neutrophil elastase (NE), vasopermeability, tissue water content and the amount of neutrophil infiltration. RESULTS XBJ treatment significantly reduced net fluid accumulation, and pulmonary vascular permeability index (PVPI), extravascular lung water index (ELWI), and water content of heart, small intestine, kidney and lung compared with LR group. Furthermore, XBJ infusion significantly reduced tissue activities of MPO and NE compared with LR group. The amount of neutrophil infiltration in LR/XBJ group was lower than that in LR group. CONCLUSIONS These results indicate that XBJ injection can reduce fluid requirements by inhibition of neutrophil protease-induced high vasopermeability and tissue edema.

Abstract
Much attention has been focused on treatment of sepsis which leads to high mortality all over the world in every year. Antioxidant activity seems to play a prominent role in the treatment of sepsis exhibited by Xuebijing injection. The aim of the present research was to develop an on-line 1, 1-diphenyl-2-picrylhydrazyl- (DPPH-) capillary electrophoresis-diode array detector (on-line DPPH-CE-DAD) method for rapidly assessing antioxidant properties and efficacious material basis of antioxidant activity as a way of quality control of Xuebijing injection. Several parameters affecting the separation were investigated, including the pH and concentrations of buffer, SDS, β-CD, and organic modifier as well as voltage and cassette temperature. Compared to previous traditional method, this improved method shortened the experimental cycle and became more efficient because it was successfully applied to analyze total antioxidant activity and contents of twelve antioxidants of Xuebijing injection under the same condition. The results revealed that the on-line DPPH-CE-DAD method was a reagent-saving, rapid, feasible, and green technique for quality control of Xuebijing injection in terms of pharmacological activity and contents of active ingredients. It also offered new opportunities for the analysis of antioxidant activity of complex matrix.

THE KOREAN JOURNAL OF PHYSIOLOGY & PHARMACOLOGY : OFFICIAL JOURNAL OF THE KOREAN PHYSIOLOGICAL SOCIETY AND THE KOREAN SOCIETY OF PHARMACOLOGY 2016; 20:565-571. [PMID: 27847433 PMCID: PMC5106390 DOI: 10.4196/kjpp.2016.20.6.565] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/24/2015] [Revised: 12/03/2015] [Accepted: 12/07/2015] [Indexed: 11/15/2022]
Abstract
Paeoniflorin (PAE) is the most abundant compound in Xuebijing injection widely used to treat sepsis. We aimed to investigate effect of PAE on expression of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in a rat model of sepsis. Wistar rats were divided into Normal, Model, and PAE groups (n=20 each). Endotoxin was administrated at 5 mg/ml/kg in Model and PAE rats to establish rat sepsis model. 1 h after endotoxin administration, PAE was administrated at 4 ml/kg in PAE group once per day for 3 days. Routine blood tests and biochemical indexes were assessed, including aspartate aminotransferase (AST) and creatine kinase-MB (CK-MB). The plasma sTREM-1 level was measured using quantitative ELISA. At the end of experiment, the small intestine, liver, kidney and lung were subjected to pathological examinations. A rat model of sepsis-induced multiple organ dysfunction syndrome (MODS) was established successfully with endotoxin administration (5 mg/ml/kg), evidenced by histo-pathological examinations, routine blood tests and biochemical indexes: platelet count decreased and white blood cell count increased (p<0.05), CK-MB and AST increased (p<0.05). PAE treatment significantly reduced the plasma levels of AST, CK-MB, and sTREM-1, compared to Model group (p<0.05). Meanwhile, sepsis-induced damages in the liver, lung, stomach and intestinal mucosa were also markedly ameliorated by PAE treatment. PAE demonstrated a significantly protective effect in a rat model of sepsis by decreasing plasma sTREM-1 level, reducing inflammation, preventing MODS and protecting organ functions.

Abstract
Xuebijing injection (XBJ) has long been used to treat infectious diseases in China. The therapeutic effect of XBJ is probably associated with anti-inflammatory effects. However, the precise mechanisms responsible for the effects of XBJ remain unknown. The present study was conducted in order to evaluate the protective effects of XBJ in a rat model of D-galactosamine (D-Gal)- and lipopolysaccharide (LPS)-induced acute liver injury. In the present study, the rats were injected with D-Gal and LPS intraperitoneally to induce acute liver injury. Two hours prior to D-Gal and LPS administration, the treatment group was administered XBJ by intravenous infusion. The effects of XBJ on D-Gal- and LPS-induced expression of tumor necrosis factor (TNF)-alpha-induced protein 8-like 2 (TIPE2), nuclear factor-κB (NF-κB), matrix metalloproteinase-9 (MMP-9) and heme oxygenase-1 (HO-1) as well as mitogen-activated protein kinase (MAPK) signaling was examined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blot analysis, immunofluorescence, as well as by analysing the serum levels of pro-inflammatory cytokines and the transaminases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Myeloperoxidase (MPO), malondialdehyde (MDA) and superoxide dismutase (SOD) levels in the rat liver tissues were also measured. For histological analysis, hematoxylin and eosin (H&E)-stained liver samples were evaluated. The results showed that XBJ upregulated TIPE2 and HO-1 expression, reduced the expression of NF-κB65 and MMP-9, inhibited the LPS-induced gene expression of c-jun N-terminal kinase (JNK) and p38 MAPK, decreased the generation of pro-inflammatory cytokines [interleukin (IL)-6, IL-13 and TNF-α], inhibited ALT and AST activity, and ameliorated D-Gal- and LPS-induced liver injury. The histological results also demonstrated that XBJ attenuated D-Gal- and LPS-induced liver inflammation. It was found that XBJ may prevent LPS-induced pro-inflammatory gene expression through inhibiting the NF-κB and MAPK signaling pathways by upregulating TIPE2 expression, thereby attenuating LPS-induced liver injury in rats. The marked protective effects of XBJ suggest that it has the potential to be used in the treatment of LPS-induced liver injury.

Abstract
Dysregulation of inflammatory cytokines and liver injury are associated with the pathogenesis of sepsis. Xuebijing injection, a Chinese herbal medicine, has been used in the treatment of sepsis and can contribute to the improvement of patients' health. However, the underlying molecular mechanisms are not yet clearly illuminated. In the present study, a septic rat model with liver injury was established by the cecal ligation and puncture (CLP) method. Histological alterations to the liver, activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), levels of inflammatory cytokine secretion and the expression of suppressors of cytokine signaling 1 (SOCS-1) in the CLP model rats with and without Xuebijing treatment were determined. The results showed that Xuebijing injection ameliorated the pathological changes in liver tissues caused by sepsis, and reduced the sepsis-induced elevation in serum ALT and AST levels. Furthermore, Xuebijing injection markedly downregulated the expression of tumor necrosis factor α and interleukin (IL)-6, and upregulated the expression of IL-10. More importantly, SOCS1 expression levels at the protein and mRNA levels were further increased by Xuebijing. These findings demonstrate that Xuebijing injection can significantly alleviate liver injury in CLP-induced septic rats via the regulation of inflammatory cytokine secretion and the promotion of SOCS1 expression. The protective effects of Xuebijing injection suggest its therapeutic potential in the treatment of CLP-induced liver injury.

Abstract
To reveal the key molecular mechanisms of Chaiqinchengqi decoction (CQCQD) in alleviating the pulmonary albumin leakage caused by endotoxemia in severe acute pancreatitis (SAP) rats. Rats models of SAP endotoxemia-induced acute lung injury were established, the studies in vivo provided the important evidences that the therapy of CQCQD significantly ameliorated the increases in plasma levels of lipopolysaccharide (LPS), sCd14, and Lbp, the elevation of serum amylase level, the enhancements of systemic and pulmonary albumin leakage, and the depravation of airways indicators, thus improving respiratory dysfunction and also pancreatic and pulmonary histopathological changes. According to the analyses of rats pulmonary tissue microarray and protein-protein interaction network, c-Fos, c-Src, and p85α were predicted as the target proteins for CQCQD in alleviating pulmonary albumin leakage. To confirm these predictions, human umbilical vein endothelial cells were employed in in vitro studies, which provide the evidences that (1) LPS-induced paracellular leakage and proinflammatory cytokines release were suppressed by pretreatment with inhibitors of c-Src (PP1) or PI3K (LY294002) or by transfection with siRNAs of c-Fos; (2) fortunately, CQCQD imitated the actions of these selective inhibitions agents to inhibit LPS-induced high expressions of p-Src, p-p85α, and c-Fos, therefore attenuating paracellular leakage and proinflammatory cytokines release.

Abstract
Toll-interacting protein (Tollip) is a mediator involved in the TLRs signaling pathway which is critical for innate immune response. In the present study, a full-length Tollip cDNA was first cloned from common carp (CcTollip), which was 1284 bp in length, containing an open reading frame of 831 bp encoding a peptide of 276 amino acids. Multiple sequence alignment showed that the CcTollip shared the highest similarity with that of grass carp and zebrafish. Phylogenetically, the CcTollip clustered together well with their piscine family members. Quantitative real-time PCR analysis indicated that CcTollip was widely expressed in all tissues tested and showed up-regulation with challenges of Vibrio anguillarum and poly(I:C), suggesting that CcTollip was activated by V. anguillarum and poly(I:C). These data indicated that CcTollip might play an important role in immune response to bacterial and viral invasion.

Abstract
Xuebijing (XBJ) is a Chinese herbal preparation. Previous studies have demonstrated that XBJ injection is able to inhibit the uncontrolled release of endogenous inflammatory mediators, attenuate inflammation, and alleviate organ damage. However, there are no relevant reports on the protective effect of XBJ against left ventricular ischemia/reperfusion (I/R)-induced acute lung injury (ALI). Therefore, the aim of the present study was to evaluate the protective effect of XBJ on ALI induced by left ventricular I/R, and provide evidence for the clinical application of XBJ. In the present study, 120 healthy rabbits of mixed gender were randomly assigned to a normal control group, ischemia group, I/R group (I/RG) and XBJ-injection treatment group (TG). In addition, each group was further divided into three subgroups (n=10/subgroup), namely, 30 min pre-ischemia, 30 min post-ischemia and 30 min post-reperfusion subgroups. Blood samples (5 ml) were collected from the jugularis externa and carotis communis of the rabbits at the three time points, and a blood gas analyzer was used to measure the arterial partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2). Following sacrifice, the lungs of the rabbits were removed and a bronchoalveolar lavage (BAL) was immediately performed. An enzyme-linked immunosorbent assay was used to measure the expression levels of tumor necrosis factor-α (TNF-α) in the BAL fluid (BALF) and peripheral blood. In addition, the lower lobe of the right lung was removed in order to measure the protein expression levels of intercellular adhesion molecule-1 (ICAM-1) and TNF-α. The results demonstrated that in the rabbits of the TG PaO2 was increased, PaCO2 was decreased, the lung tissue congestion edema was attenuated, the expression levels of TNF-α in the peripheral blood and BALF were reduced and the protein expression levels of ICAM-1 and TNF-α in the lung tissue samples were decreased, as compared with those in the I/RG rabbits. These results suggest that XBJ may protect against left ventricular I/R-induced ALI by regulating the expression of the inflammatory mediators TNF-α and ICAM-1.

Abstract
The aim of the present study was to investigate the effects of high mobility group protein B1 (HMGB1), which is expressed in the serum of patients with sepsis, on vascular endothelial permeability. Sera from patients with sepsis were used to treat endothelial cells (ECs), and the effect on endothelial permeability was evaluated using immunofluorescence. The morphologies of endothelial cytoskeletal actin and vascular endothelial (VE)‑cadherin were assessed using laser scanning confocal microscopy. The protein expression levels of HMGB1, B‑cell lymphoma 2 (BCL‑2) and BCL‑2‑associated X protein (BAX) were detected using western blotting. EC apoptosis was measured using flow cytometry. The results demonstrated that HMGB1 was significantly expressed in the serum 24 h following the onset of sepsis, and the expression levels peaked at 48 h, which were sustained until 96 h post‑onset. Compared with the control group, treatment of the ECs with 20% septic serum in vitro significantly increased endothelial monolayer permeability (P<0.01), markedly induced transcellular filamentous (F)‑actin rearrangement with stress fiber formation, and resulted in the localization of VE‑cadherin fragmentations at the cell borders with increased gaps between ECs. Furthermore, flow cytometry showed that the apoptotic rate of ECs was significantly increased following treatment with septic serum. In addition, the expression levels of BAX were significantly increased, whereas the expression levels of BCL‑2 were significantly decreased. Pretreatment with an HMGBI inhibitor (ethyl pyruvate; 5 µM) 24 h prior to treatment with the septic serum attenuated the effects of septic serum treatment. Together, these findings suggested that treatment of ECs with sera from patients with sepsis may induce the loss of vascular endothelial monolayer integrity, elicit the formation of endothelial F‑actin stress fibers and initiate VE‑cadherin redistribution, which may be attributed to high levels of HMGB1 in the serum. This mechanism also appears to involve changes in the activation of BAX and BCL‑2, resulting in EC apoptosis.

Abstract
The Chinese herb preparation Xuebijing injection (XBJ) has been widely used in the management of various septic disorders or inflammation-related conditions, however the molecular mechanism of its anti-inflammatory effect remains largely elusive. In the current study, we found that XBJ treatment potently ameliorated mouse hepatic ischemia-reperfusion (IR) injury, manifested as decreased liver function tests (LDH, ALT, AST), improved inflammation and less hepatocyte apoptosis. Notably, XBJ markedly inhibited inflammasome activation and IL-1 production in mouse livers subjected to IRI, even in the absence of Kupffer cells, suggesting Kupffer cells are not necessary for hepatic inflammasome activation upon Redox-induced sterile inflammation. This finding led us to investigate the role of XBJ on hepatocyte apoptosis and inflammasome activation using an in vitro hydrogen peroxide (H2O2)-triggered hepatocyte injury model. Our data clearly demonstrated that XBJ potently inhibited apoptosis, as well as caspase-1 cleavage and IL-1β production in a time- and dose-dependent manner in isolated hepatocytes, suggesting that in addition to its known modulatory effect on NF-κB-dependent inflammatory gene expression, it also has a direct impact on hepatocyte inflammasome activation. The current study not only deepens our understanding of how XBJ ameliorates inflammation and apoptosis, but also has immediate practical significance in many clinical situations such as partial hepatectomy, liver transplantation, etc.

Abstract
A typical indicator of sepsis is the development of progressive subcutaneous and body-cavity edema, which is caused by the breakdown of endothelial barrier function, leading to a marked increase in vascular permeability. Microvascular leakage predisposes to microvascular thrombosis, breakdown of microcirculatory flow and organ failure, which are common events preceding mortality in patients with severe sepsis. Melilotus suaveolens (M. suaveolens) is a Traditional Tibetan Medicine. Previous pharmacological studies have demonstrated that an ethanolic extract of M. suaveolens has powerful anti-inflammatory activity and leads to an improvement in capillary permeability. However, the mechanisms underlying its pharmacological activity remain elusive. The present study aimed to assess the impact of M. suaveolens extract tablets on pulmonary vascular permeability, and their effect on regulating lung inflammation and the expression of vascular endothelial growth factor (VEGF) in the lung tissue of rats with sepsis. A cecal ligation and puncture (CLP) sepsis model was established for both the control and treatment groups. ~2 h prior to surgery, 25 mg/kg of M. suaveolens extract tablet was administered to the treatment group. Polymerase chain reaction and western blot analyses were used to assess the expression of nuclear factor (NF)-κB and VEGF in the lung tissue, and ELISA was applied to detect changes in serum tumor necrosis factor-α as well as interleukins (IL) -1, -4, -6, and -10. The lung permeability, wet/dry weight ratio and lung pathology were determined. The results demonstrated that in the lung tissue of CLP-rats with sepsis, M. suaveolens extract inhibited the expression of NF-κB, reduced the inflammatory response and blocked the expression of VEGF, and thus significantly decreased lung microvascular permeability. The effects of M. Suaveolens extract may be of potential use in the treatment of CLP-mediated lung microvascular permeability.
