J Microsc Ultrastruct 2023; 11:135-144. [PMID: 38025187 PMCID: PMC10679830 DOI: 10.4103/jmau.jmau_115_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 09/13/2021] [Accepted: 10/27/2021] [Indexed: 11/10/2022] Open
Abstract
Introduction Gastrointestinal (GIT) mucositis is a common problem associated with chemotherapy. Dacomitinib is a chemotherapeutic drug that treats nonsmall cell lung cancer. It irreversibly binds to the receptors at the ileal epithelial cells, leading to mucosal injury. Baicalin (BA) is a flavonoid with anti-inflammatory, antifibrosis, and antibarrier disruption properties. Aim This work aimed to investigate the possible protective effects of BA on dacomitinib-induced ileal mucositis in rats by histological and immunohistochemical studies. Materials and Methods 60 Wistar rats (8-12 weeks) were used (180-200 g) and divided into 6 groups (10 rats each). Group 1: Control; Group 2 (dacomitinib): Rats received dacomitinib 7.5 mg/kg/day orally; Group 3 (dacomitinib + carboxyl methylcellulose [CMC]): Rats received dacomitinib 7.5 mg/kg/day and 0.5% CMC orally; Group 4 (dacomitinib + BA low dose): Rats received low-dose BA 30 mg/kg/day and 7.5 mg/kg/day dacomitinib orally; Group 5 (dacomitinib + BA mid dose): Rats received mid-dose BA 60 mg/kg/day and 7.5 mg/kg/day dacomitinib orally; Group 6 (dacomitinib + BA high dose): Rats received high-dose BA 100 mg/kg/day and 7.5 mg/kg/day dacomitinib orally. Results Dacomitinib group showed short villi, desquamated epithelium, congested blood vessels, inflammatory cellular infiltrations, dilated lacteals, and wide spaces between the crypts. There is a significant increase in collagen fibers and number of tumor necrosis factor-alpha and proliferating cell nuclear antigen-positive cells. Further, there were lost epithelial cadherin (E-cadherin) and epidermal growth factor receptor immunohistochemical reaction. The previous findings were ameliorated by BA in a dose-dependent manner. Conclusion BA has a protective effect through its anti-inflammatory, antifibrosis, and antibarrier disruption effects. Hence, BA is considered as a promising new drug for the treatment of chemotherapy-associated GIT problems, especially dacomitinib.

A Study Based on Metabolomics, Network Pharmacology, and Experimental Verification to Explore the Mechanism of Qinbaiqingfei Concentrated Pills in the treatment of Mycoplasma Pneumonia. Front Pharmacol 2021; 12:761883. [PMID: 34803705 PMCID: PMC8599429 DOI: 10.3389/fphar.2021.761883] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 09/27/2021] [Indexed: 12/13/2022] Open
Abstract
Qinbaiqingfei concentrated pills (QB) are a commonly used medicine for the treatment of mycoplasma pneumonia in China, and the mechanism of action of QB needs to be studied further. Therefore, we use a combination of metabolomics and network pharmacology to clarify the mechanism of QB. Nontarget metabolomics studies were performed on rat serum, urine, and lung tissues, and 56 therapeutic biomarkers were found. Subsequently, the components of QB absorbed into the blood and lung tissues were clarified, and based on this finding, the core target of network pharmacology was predicted. The enrichment analysis of biomarkers–genes finally confirmed their close relationship with the NF-κB signaling pathway. By western blotting expression of the proteins in the lung tissue–related signaling pathways, it is finally confirmed that QB inhibits the NF-κB signaling pathway through SIRT1, IL-10 and MMP9, CTNNB1, EGFR, and other targets. It plays a role in regulating immunity, regulating metabolism, and treating diseases.

Abstract
Mycoplasma pneumoniae (MP) is a common pathogen that can cause respiratory infections. MP pneumonia (MPP) leads to numerous complications, including lung injury and even death. The present study aimed to investigate the protective effects of Baicalin treatment on MP infection‑induced lung injury and the molecular mechanism underlying these effects. Briefly, after mice were infected intranasally by MP and treated with Baicalin (80 mg/kg), serum levels of MP‑immunoglobulin M (IgM) were detected by ELISA. The expression levels of C‑reactive protein (CRP) in lung tissue were detected by immunohistochemistry and the bronchoalveolar lavage fluid (BALF) was examined by ELISA. Inflammatory factors and inflammatory cells in the BALF were assessed. The expression levels of microRNA (miR)‑221 in lung tissue were examined by reverse transcription‑quantitative PCR and pathological changes in lung tissue were detected by H&E staining. Cell apoptosis was evaluated by TUNEL assay and the protein expression levels of TLR4, MyD88 and NF‑κB were detected by western blotting. Baicalin treatment significantly reduced serum levels of MP‑IgM and CRP expression in lung tissue during MP infection. In addition, Baicalin decreased the levels of IL‑1β, IL‑6, IL‑18 and TNF‑α in the BALF, and the number of inflammatory cells. Baicalin also reduced the inflammatory infiltration in lung tissue induced by MP infection, improved the pathological changes detected in lung tissue, reduced apoptosis, and downregulated the protein expression levels of TLR4, MyD88 and NF‑κB. Furthermore, Baicalin treatment downregulated the expression of miR‑221 and the protective effects of Baicalin were attenuated by miR‑221 overexpression. In conclusion, Baicalin has a therapeutic effect on mice with MP infection‑induced lung injury, which may be related to inhibition of miR‑221 expression and regulation of the TLR4/NF‑κB signaling pathway.

Abstract
The metabolic profiles of Tanreqing injection, which is a traditional Chinese medicine recommended for complementary administration to treat a novel coronavirus, have remained unclear, which inhibit the understanding of the effective chemical compounds of Tanreqing injection. In this study, a sensitive high-performance liquid chromatography quadrupole time-of-flight mass spectrometry method was used to identify the compounds and metabolites in various biosamples, including plasma, bile, liver, lung, kidney, urine, and feces, following the intravenous administration of Tanreqing injection in rats. A total of 89 compounds were characterized in the biosamples of Tanreqing injection-treated rats including 25 precursor constituents and 64 metabolites. Nine flavonoid compounds, twelve phenolic acids, and four iridoid glycosides were identified in the rats. Their metabolites were mainly produced by glucuronidation, deglucuronidation, glycosylation, deglycosylation, methylation, demethylation, N-heterocyclisation, sulphation, dehydroxylation, decarboxylation, dehydration, hydroxylation, and corresponding recombination reactions. This study was the first to comprehensively investigate the metabolic profile of Tanreqing injection and provides a scientific basis to further elucidate the pharmacodynamic material basis and therapeutic mechanism of Tanreqing injection.

Abstract
1. Mycoplasma gallisepticum (MG) causes severe lung inflammation and cell damage by activating toll-like receptor (TLR) signalling, the nuclear factor-kappaB (NF-κB) pathway and pro-inflammatory cytokine gene expression. Baicalin (BA) is a flavonoid extracted from Scutellaria baicalensis, which possesses anti-inflammatory and anti-bacterial properties. This study investigated the effect of BA in MG-induced lung inflammation and its potential mechanism in MG-infected chicken embryo lungs and DF-1 cells.2. The histopathological examination result showed that BA treatment alleviated MG-induced lung pathological changes. In addition, CCK-8 and cell cycle assays showed that BA treatment inhibited MG-induced cell proliferation and cell cycle progression in DF-1 cells.3. The ELISA and RT-qPCR results demonstrated that BA treatment decreased the expression of interleukin-1beta (IL-1β), IL-6, and tumour necrosis factor-alpha (TNF-α) both in MG-infected chicken embryo lungs and DF-1 cells.4. The results revealed that BA inhibited mRNA expression levels of toll-like receptor-6 (TLR6), myeloid differentiation primary response gene-88 (MyD88) and nuclear factor-κB (NF-κB), and the nuclear translocation of NF-κB-p655. In conclusion, the results showed that BA has a protective effect against MG-induced lung inflammation in chicken by inhibiting the TLR6-mediated NF-κB signalling.

BMC Complement Med Ther 2020; 20:289. [PMID: 32962697 PMCID: PMC7507634 DOI: 10.1186/s12906-020-03081-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 09/13/2020] [Indexed: 01/17/2023] Open
Abstract
Background In recent years, it has been reported that Qinbai Qingfei Concentrated Pellet (QQCP) has the effect of relieving cough and reducing sputum. However, the therapeutic potentials of QQCP on post-infectious cough (PIC) rat models has not been elucidated. So the current study was aimed to scientifically validate the efficacy of QQCP in post infectious cough. Methods All rats were exposed to sawdust and cigarette smokes for 10 days, and intratracheal lipopolysaccharide (LPS) and capsaicin aerosols. Rats were treated with QQCP at dose of 80, 160, 320 mg/kg. Cough frequency was monitored twice a day for 10 days after drug administration. Inflammatory cell infiltration was determined by ELISA. Meanwhile, the histopathology of lung tissue and bronchus in rats were evaluated by hematoxylin-eosin staining (H&E). Neurogenetic inflammation were measured by ELISA and qRT-PCR. Results QQCP dose-dependently decreased the cough frequency and the release of pro-inflammatory cytokines TNF-α, IL-1β, IL-6 and IL-8, but exerted the opposite effects on the secretion of anti-inflammatory cytokines IL-10 and IL-13 in BALF and serum of PIC rats. The oxidative burden was effectively ameliorated in QQCP-treated PIC rats as there were declines in Malondialdehyde (MDA) content and increases in Superoxide dismutase (SOD) activity in the serum and lung tissue. In addition, QQCP blocked inflammatory cell infiltration into the lung as evidenced by the reduced number of total leukocytes and the portion of neutrophils in the broncho - alveolar lavage fluid (BALF) as well as the alleviated lung damage. Furthermore, QQCP considerable reversed the neurogenetic inflammation caused by PIC through elevating neutral endopeptidase (NEP) activity and reducing Substance P (SP) and Calcitonin gene related peptide (CGRP) expression in BALF, serum and lung tissue. Conclusions Our study indicated that QQCP demonstrated a protective role of PIC and may be a potential therapeutic target of PIC.

Abstract
Mycoplasma gallisepticum (MG) infection produces a profound inflammatory response in the respiratory tract and evade birds' immune recognition to establish a chronic infection. Previous reports documented that the flavonoid baicalin possess potent anti-inflammatory, and antioxidant activities. However, whether baicalin prevent immune dysfunction is largely unknown. In the present study, the preventive effects of baicalin were determined on oxidative stress generation and apoptosis in the spleen of chickens infected with MG. Histopathological examination showed abnormal morphological changes including cell hyperplasia, lymphocytes depletion, and the red and white pulp of spleen were not clearly visible in the model group. Oxidative stress-related parameters were significantly (P < 0.05) increased in the model group. However, baicalin treatment significantly (P < 0.05) ameliorated oxidative stress and partially alleviated the abnormal morphological changes in the chicken spleen compared to model group. Terminal deoxynucleotidyl transferase–mediated dUTP nick endlabeling assay results, mRNA, and protein expression levels of mitochondrial apoptosis-related genes showed that baicalin significantly attenuated apoptosis. Moreover, baicalin restored the mRNA expression of mitochondrial dynamics-related genes and maintain the balance between mitochondrial inner and outer membranes. Intriguingly, the protective effects of baicalin were associated with the upregulation of nuclear factor erythroid 2–related factor 2 (Nrf2)/Heme oxygenase-1 (HO-1) pathway and suppression of nuclear factor-kappa B (NF-κB) pathway in the spleen of chicken. In summary, these findings indicated that baicalin promoted mitochondrial dynamics imbalance and effectively prevents oxidative stress and apoptosis in the splenocytes of chickens infected with MG.

Abstract
Background Baicalin possesses potential anti-inflammatory, anti-tumor and anti-oxidant activities. In the present study, we attempted to investigate the preventive effects of baicalin against Mycoplasma gallisepticum (MG)-induced inflammation, apoptosis and energy metabolism dysfunction in chicken lungs. Methods Experimental chickens were randomly divided into 1) control group, 2) MG infection group, 3) MG-infected group treated with baicalin at a dose of 450 mg/kg and 4) baicalin alone treated group (450 mg/kg). After 7 days of post-treatment, serum and lung tissues were collected for different experimental analyses. The hallmarks of inflammation, apoptosis and energy metabolism dysfunction were detected by histological and ultrastructural examination, qRT-PCR, Western blotting and terminal deoxynucleotidyl transferase-mediated dUTP nick endlabeling (TUNEL) assay. Results The level of serum inflammatory markers were increased with MG infection. Histological and ultrastructural analysis showed excessive inflammatory cells infiltrates, alveolar wall thickening, hemorrhages, mitochondrial and nuclear damage, including mitochondrial swelling and condensation of DNA in the lungs of chickens infected with MG. TUNEL assay positive-stained nuclei were significantly increased in MG infection group. In addition, the mRNA and protein expression level of energy metabolism-related genes and ATPase activities were significantly reduced. Meanwhile, MG-induced morphological and ultrastructural changes were partially disappeared with baicalin-treatment, and the level of serum inflammatory markers were significantly reduced. It has been noted that baicalin significantly attenuated MG-induced inflammation and apoptosis in the chicken lungs through the suppression of nuclear factor-kappa B and reduced extensive positive-stained apoptotic nuclei. More importantly, ATPase activities and mRNA and protein expression level of energy metabolism-related genes were significantly improved with baicalin-treatment in the lungs of chickens infected with MG. Conclusion Conclusively, it has been suggested from these results that baicalin-treatment efficiently prevented MG-induced inflammation, apoptosis and energy metabolism dysfunction in the chicken lungs and provide basis for new therapeutic targets to control MG infection.

[PMID: 28073091 DOI: 10.1016/j.etap.2017.01.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2016] [Revised: 12/29/2016] [Accepted: 01/01/2017] [Indexed: 06/06/2023]
Abstract
Platycodin D is one of the most important monomers of the Qinbaiqingfei pellet (Qinbai), which has already been approved as the first effective new Traditional Chinese Medicine used to fight against Mycoplasma pneumoniae (M. pneumoniae) in clinic in China. In previous studies, pharmacodynamics experiment has proved that Platycodin D has anti-M. pneumoniae effect and the minimum inhibitory concentration (MIC) is 16mμg/ml. This paper further clarified that the mechanism underlying the anti-M. pneumoniae effect of Platycodin D might be due to M. pneumoniae adhesion proteins P1 and P30. P1 and P30 expression levels in M. pneumoniae strain, M. pneumoniae-infected BALB/c mice, and M. pneumoniae-infected A549 cells were determined by reverse transcription PCR. Platycodin D strongly inhibited P1 and P30 expression in M. pneumonia and high dosage of Platycodin D exhibited a greater effect on reducing P1 and P30 expression than low dose Platycodin D. Platycodin D prevented M. pneumoniae infection through inhibiting the expression of adhesion proteins, which might be one of the mechanisms for the anti-M. pneumoniae properties of Qinbai. These results provide a foundation to further explore the mechanisms of action of Qinbai in future studies.

The inhibition of Platycodin D on Mycoplasma pneumoniae proliferation and its effect on promoting cell growth after anti-Mycoplasma pneumoniae treatment. Front Cell Infect Microbiol 2015; 4:192.

Abstract
Platycodin D, extract from the root of Platycodon grandiflorum, is one of the most important monomers of the Qinbaiqingfei pellets (Qinbai) that has already been approved as the first Traditional Chinese Medicine for clinic use as an anti-M. pneumoniae agent. Qinbai constituents Scutellaria baicalensis and Platycodon grandiflorum were used to treat thousands of patients clinically in China each year. In this study, a M. pneumoniae–infected mouse strain, BALB/c, and a human-derived epithelial cell line, A549 type II pneumocytes, were used as experimental model. Anti-M. pneumoniae effect of Platycodin D was measured by the Real-time quantitative PCR, while the cell pathological change with hematoxylin and eosin and the growth recovery effects were determined with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and Trypan Blue dye in the experimental model after M. pneumoniae infection. Our research results showed that Platycodin D could significantly inhibit M. pneumoniae and promote cell growth after anti- M. pneumoniae treatment in the infected cells or mice.

Effects of Traditional Chinese Medicine Qinbai Qingfei Concentrated Pellet on Cellular Infectivity of Mycoplasma pneumoniae. INTERNATIONAL SCHOLARLY RESEARCH NOTICES 2014; 2014:751349. [PMID: 27433528 PMCID: PMC4897063 DOI: 10.1155/2014/751349] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2014] [Accepted: 09/10/2014] [Indexed: 11/17/2022]
Abstract
Aim. To study the effect and mechanism of traditional Chinese medicine Qinbai Qingfei concentrated pellet (QQCP) against Mycoplasma pneumoniae (MP). Methods. Rat airway smooth muscle (ASM) cells were used to examine the antimycoplasmal activity of QQCP via four drug-adding modes: pre- and postadding drugs, simultaneous-adding after drug and MP mixed, and simultaneous-adding drug and MP; taking roxithromycin dispersive tablets (RDT) as positive control, the cellular A570 values were determined by MTT method. Results. All of A570 values in QQCP group were significantly higher than those of the corresponding MP control group (P < 0.01) in four drug-adding modes; there was no significant difference in A570 values between the QQCP group and that of the positive control group (P > 0.05), confirming that QQCP could significantly inhibit the infectivity of MP to ASM cells. Conclusion. QQCP had significant activity in preventing and treating MP infection, killing MP, and antiabsorption.
