Stachydrine, a Bioactive Equilibrist for Synephrine, Identified from Four Citrus Chinese Herbs.

Four Chinese herbs from the Citrus genus, namely Aurantii Fructus Immaturus (Zhishi), Aurantii Fructus (Zhiqiao), Citri Reticulatae Pericarpium Viride (Qingpi) and Citri Reticulatae Pericarpium (Chenpi), are widely used for treating various cardiovascular and gastrointestinal diseases. Many ingredients have already been identified from these herbs, and their various bioactivities provide some interpretations for the pharmacological functions of these herbs. However, the complex functions of these herbs imply undisclosed cholinergic activity. To discover some ingredients with cholinergic activity and further clarify possible reasons for the complex pharmacological functions presented by these herbs, depending on the extended structure-activity relationships of cholinergic and anti-cholinergic agents, a simple method was established here for quickly discovering possible choline analogs using a specific TLC method, and then stachydrine and choline were first identified from these Citrus herb decoctions based on their NMR and HRMS data. After this, two TLC scanning (TLCS) methods were first established for the quantitative analyses of stachydrine and choline, and the contents of the two ingredients and synephrine in 39 samples were determined using the valid TLCS and HPLC methods, respectively. The results showed that the contents of stachydrine (3.04‱) were 2.4 times greater than those of synephrine (1.25‱) in Zhiqiao and about one-third to two-thirds of those of Zhishi, Qingpi and Chenpi. Simultaneously, the contents of stachydrine, choline and synephrine in these herbs present similar decreasing trends with the delay of harvest time; e.g., those of stachydrine decrease from 5.16‱ (Zhishi) to 3.04‱ (Zhike) and from 1.98‱ (Qingpi) to 1.68‱ (Chenpi). Differently, the contents of synephrine decrease the fastest, while those of stachydrine decrease the slowest. Based on these results, compared with the pharmacological activities and pharmacokinetics reported for stachydrine and synephrine, it is indicated that stachydrine can be considered as a bioactive equilibrist for synephrine, especially in the cardio-cerebrovascular protection from these citrus herbs. Additionally, the results confirmed that stachydrine plays an important role in the pharmacological functions of these citrus herbs, especially in dual-directionally regulating the uterus, and in various beneficial effects on the cardio-cerebrovascular system, kidneys and liver.

Tingli Dazao Xiefei Decoction ameliorates asthma in vivo and in vitro from lung to intestine by modifying NO–CO metabolic disorder mediated inflammation, immune imbalance, cellular barrier damage, oxidative stress and intestinal bacterial disorders

Ethnopharmacological relevanceAsthma is a chronic airway inflammatory disease. Current treatment of mainstream medications has significant side effects. There is growing evidence that the refractoriness of asthma is closely related to common changes in the lung and intestine. The lungs and intestines, as sites of frequent gas exchange in the body, are widely populated with gas signaling molecules NO and CO, which constitute NO–CO metabolism and may be relevant to the pathogenesis of asthma in the lung and intestine. The Chinese herbal formula Tingli Dazao Xiefei Decoction (TD) is commonly used in clinical practice to treat asthma with good efficacy, but there are few systematic evaluations of the efficacy of asthma on NO–CO metabolism, and the mode of action of its improving effect on the lung and intestine is unclear. Aim of the studyTo investigate the effect of TD on the lung and intestine of asthmatic rats based on NO–CO metabolism. Materials and methodsIn vivo, we established a rat asthma model by intraperitoneal injection of sensitizing solution with OVA atomization, followed by intervention by gavage administration of TD. We simultaneously examined alterations in basal function, pathology, NO–CO metabolism, inflammation and immune cell homeostasis in the lungs and intestines of asthmatic rats, and detected changes in intestinal flora by macrogenome sequencing technology, with a view to multi-angle evaluation of the treatment effects of TD on asthmatic rats. In vitro, lung cells BEAS-2B and intestinal cells NCM-460 were used to establish a model of lung injury causing intestinal injury using LPS and co-culture chambers, and lung cells or intestinal cells TD-containing serum was administered to intervene. Changes in inflammatory, NO–CO metabolism-related, cell barrier-related and oxidative stress indicators were measured in lung cells and intestinal cells to evaluate TD on intestinal injury by way of amelioration and in-depth mechanism. ResultsIn vivo, our results showed significant basal functional impairment in the lung and intestine of asthmatic rats, and an inflammatory response, immune cell imbalance and intestinal flora disturbance elicited by NO–CO metabolic disorders were observed (P < 0.05 or 0.01). The administration of TD was shown to deliver a multidimensional amelioration of the impairment induced by NO–CO metabolic disorders (P < 0.05 or 0.01). In vitro, the results showed that LPS-induced lung cells BEAS-2B injury could cause NO–CO metabolic disorder-induced inflammatory response, cell permeability damage and oxidative stress damage in intestinal cells NCM-460 (P < 0.01). The ameliorative effect on intestinal cells NCM-460 could only be exerted when TD-containing serum interfered with lung cells BEAS-2B (P < 0.01), suggesting that the intestinal ameliorative effect of TD may be exerted indirectly through the lung. ConclusionTD can ameliorate NO–CO metabolism in the lung and thus achieve the indirectly amelioration of NO–CO metabolism in the intestine, ultimately achieving co-regulation of lung and intestinal inflammation, immune imbalance, cellular barrier damage, oxidative stress and intestinal bacterial disorders in asthma in vivo and in vitro. Targeting lung and intestinal NO–CO metabolic disorders in asthma may be a new therapeutic idea and strategy for asthma.

Jian-Pi-Yi-Shen formula restores iron metabolism from dysregulation in anemic rats with adenine-induced nephropathy

Ethnopharmacological relevanceJian-Pi-Yi-Shen (JPYS) is a herbal decoction being used to relieve the symptoms of chronic kidney disease (CKD) and its complications, including anemia, for over twenty years. Nonetheless, it is unclear how JPYS influences renal anemia and iron metabolism. Aim of the studyAn analysis of network pharmacology, chemical profiling, and in vivo experiments was conducted to identify the impact of JPYS on JAK2-STAT3 pathway and iron utilization in renal anemia and CKD. Materials and methodsThe chemical properties of JPYS and its exposed ingredients were detected in vivo. And based on the aforesaid chemical compounds, the potential targets and signaling pathways of JPYS for renal anemia treatment were predicted by network pharmacology. Afterward, an adenine-feeding animal model of CKD-related anemia was developed to verify the mechanism by which JPYS modulates iron recycling to treat renal anemia. Renal injury was estimated by serum creatinine (Scr), blood urea nitrogen (BUN), histopathological examinations and fibrosis degree. Western blot, enzyme-linked immunosorbent assay (ELISA), quantitative real-time polymerase chain reaction (qPCR) and immunohistochemistry approaches were utilized to assess the levels of JAK2, STAT3 and iron metabolism-related factors. ResultsThere were 164 active ingredients identified in JPYS, including prototypes and metabolites in vivo were identified in JPYS, and 21 core targets were found through network pharmacology based on topological characteristics. Combined with the core targets and pathway enrichment analysis, the majority of the candidate targets were associated with the JAK2-STAT3 signaling pathways. Experimental results indicated that JPYS treatment significantly decreased the expression of BUN and Scr, restored renal pathological damage, down-regulated fibrosis degree, and improved hematological parameters such as red blood cell, hemoglobin and hematocrit in CKD rats. Furthermore, JPYS significantly restored iron metabolism from dysregulation by increasing the levels of iron and ferritin in the serum, inhibiting the production of hepcidin in liver and serum, and regulating transferrin receptor 1 in bone marrow. Meanwhile, the expression of JAK2 and STAT3 was suppressed by JPYS treatment. ConclusionsBased on these results, JPYS reduces hepcidin levels by inhibiting the activation of JAK2-STAT3 signaling, thereby protecting against iron deficiency anemia.

Chromatographic Method for Monitoring of Pesticide Residues and Risk Assessment for Herbal Decoctions Used in Traditional Korean Medicine Clinics.

The presence of pesticide residues in herbs and the herbal products derived from them raises serious health concerns. This study was conducted to investigate the residual pesticide concentrations and assess potential human health risks from herbal medicines used in traditional Korean medicine clinics. A total of 40 samples of herbal decoctions were collected from 10 external herbal dispensaries. The pesticide residues were analyzed by the multiresidue method for 320 different pesticides using liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography tandem mass spectrometry (GC-MS/MS). As a result of the monitoring, carbendazim was detected at 0.01 and 0.03 μg/g in eight samples and no pesticide was detected in the other herbal decoctions. Carbendazim was set for each individual item as less than 0.05 μg/g in Paeoniae radix, less than 0.05 μg/g in Cassiae semen, less than 2.0 μg/g in Lycii fructus, and less than 10 μg/g in Schisandrae fructus (dried). Therefore, the results of this study suggested that the detected pesticide residues in herbal decoctions could not be considered as posing a serious health risk.

Correlation between traditional Chinese medicine and reduced risk of readmission in rheumatoid arthritis patients with hypoproteinemia:a retrospective cohort study

This study aimed to explore the correlation between traditional Chinese medicine(TCM) and reduced risk of readmission in patients having rheumatoid arthritis with hypoproteinemia(RA-H). A retrospective cohort study was conducted on 2 437 rheumatoid arthritis patients in the information system database of the First Affiliated Hospital of Anhui University of Chinese Medicine from 2014 to 2021, and 476 of them were found to have hypoproteinemia. The patients were divided into TCM users and non-TCM users by propensity score matching. Exposure was defined as the use of oral Chinese patent medicine or herbal decoction for ≥1 month. Cox regression analysis was performed to explore the risk factors of clinical indicators of rheumatoid arthritis. Additionally, the use of TCM during hospitalization was analyzed, and analysis of association rules was conducted to investigate the correlation between TCM, improvement of indicators and readmission of patients. Kaplan-Meier survival curve was plotted to compare the readmission rate of TCM users and non-TCM users. It was found the readmission rate of RA-H patients was significantly higher than that of RA patients. By propensity score matching, 232 RA-H patients were divided into TCM group(116 cases) and non-TCM group(116 cases). Compared with the conditions in the non-TCM group, the readmission rate of the TCM group was lowered(P&lt;0.01), and the readmission rate of middle-aged and elderly patients was higher than that of young patients(P&lt;0.01). Old age was a risk factor for readmission of RA-H patients, while TCM, albumin(ALB) and total protein(TP) were the protective factors. During hospitalization, the TCMs used for RA-H patients were mainly divided into types of activating blood and resolving stasis, relaxing sinew and dredging collaterals, clearing heat and detoxifying, and invigorating spleen and resolving dampness. The improvement of rheumatoid factor(RF), immunoglobulin G(IgG), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and ALB was closely related to TCM. On the basis of western medicine treatment, the application of TCM could reduce the readmission rate of RA-H patients, and longer use of TCM indicated lower readmission rate.

Immunomodulatory Activity of the Aqueous Extract of the pith of Citrus limon L. (Rutaceae) Using Cyclophosphamide Induced Myelosuppression

The genus Citrus species have been widely used in the relief of arthritic pain in traditional medicine. Citrus limon pith was one of the constituents of herbal decoctions taking daily for prevention against Coronavirus disease during covid -19 era. This study investigated the immunomodulatory activity of the aqueous extract of the pith of C. limon using cyclophosphamide-induced myelosuppression and delayed type hypersensitivity reaction in Wistar rats. Thirty-six rats were divided into six groups of six animals each. Three groups served as the control while the remaining three groups were given 150, 300, 600 mg/kg of extract respectively via oral route for 13 days. Groups II to VI were administered cyclophosphamide 30 mg/kg i.p on day 11, 12, and 13. On the 14th day, blood samples were collected for haematological parameters analysis. Delayed type hypersensitivity reaction was carried out using 24 animals divided into four groups of six animals each. Phytochemical screening revealed the presence of triterpenoids, flavonoids, and carbohydrates. LD50 was found to be greater than 3000 mg/kg. C. limon extract on cyclophosphamide-induced myelosuppression showed a statistically significant (P&lt;0.05) increase in the white blood cells (WBC), platelets and lymphocytes counts at all extract doses. In the delayed type of hypersensitivity reaction, percentage increase in inflammation was 24.3%, 31.5% and 43% at extract doses of 150, 300 and 600 mg/kg. The findings of this study have shown that the aqueous extract of the pith of C. limon possessed immunostimulatory activity.

Jie Geng Tang reverses cisplatin resistance through the Nrf2 pathway in lung cancer

Jie Geng Tang (JGT) is an ancient traditional Chinese herbal decoction that exhibits various pharmacological activities, however, is poorly understood in the sensitivity of lung cancer to chemotherapy. Here, we explored the effect of JGT on sensitizing cisplatin (DDP)-resistant A549 cells (A549/DDP). Cell viability was assessed using cell counting kit-8 assay. Flow cytometry was applied to detected cell apoptosis, mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) levels. Western blotting and qRT-PCR were performed to determine protein and mRNA levels. The results demonstrated that DDP co-treatment with JGT significantly increased the cytotoxicity of A549/DDP cells and exhibited efficacy in suppressing the migration and proliferation. The rate of apoptosis was increased by co-treatment with DDP and JGT, along with a higher rate of Bax/Bcl-2, and increased loss of MMP. Furthermore, the combination promoted ROS accumulation and increased γ-H2AX levels. Moreover, Nrf2 levels were suppressed in a dose- and time-dependent manner, Nrf2 stability was reduced following treatment with JGT. Notably, the combination induced inhibition of the Nrf2/ARE pathway at the mRNA and protein levels. Collectively, these results indicate that co-treatment with JGT and DDP can be considered a combinational approach to treating DDP resistance.

Network pharmacology-based mechanism prediction and pharmacological validation of Bushenhuoxue formula attenuating postmenopausal osteoporosis in ovariectomized mice

BackgroundBushenhuoxue (BSHX) formula, a ten-compound herbal decoction, is widely used to treat postmenopausal osteoporosis (PMOP) in China. However, the mechanism is not clear yet.MethodsThe underlying biological processes and signaling pathways were predicted by network pharmacology. In vivo experimental study, 24 female C57BL/6 J mice were randomly divided into sham, ovariectomized (OVX) and BSHX formula groups. Mice in the latter two groups were subjected to bilateral ovariectomy, and mice in the BSHX formula group were extra treated by BSHX formula at an oral dosage of 0.2 mL/10 g for 8 weeks. The femur samples were harvested for tissue analyses including μCT assay, histology and immunohistochemical (IHC) staining of VEGF signaling.ResultsA total of 218 active ingredients and 274 related targets were identified in BSHX formula. After matching with 292 targets of PMOP, 64 overlapping genes were obtained. GO and KEGG enrichment analyses on these 64 genes revealed that angiogenesis and VEGF signaling were considered as the potential therapeutic mechanism of BSHX formula against PMOP. Animal experiments showed that mice in the BSHX formula-treated group presented increased bone mass, microstructural parameters, blood vessel numbers and an activation of VEGF signaling (VEGF, COX2, eNOS and CD31) compared to the OVX mice.ConclusionThis study revealed that BSHX formula exerts anti-PMOP effects possibly through activating VEGF signaling-mediated angiogenesis.

Deciphering the molecular mechanisms of Maxing Huoqiao Decoction in treating pulmonary fibrosis via transcriptional profiling and circRNA-miRNA-mRNA network analysis

BackgroundIdiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial lung condition with unknown etiology and high mortality. Chinese herbal medicine has been used for more than a thousand years to treat various lung diseases. PurposeThe current study aimed to examine whether Chinese herbal Maxing Huoqiao Decoction (MXHQD) exerts therapeutic effects on IPF and to further uncover its underlying molecular mechanisms. MethodsMouse model of acute lung injury (ALI) or IPF was induced by intratracheal instillation of LPS or bleomycin, respectively. ALI mice were treated with MXHQD for 7 days, and lung tissues were taken for test after modeling 24 h. IPF mice were gavaged for 21 days after modeling. Lung tissues were subjected to whole transcriptome detection, and the differential RNAs were experimentally verified. ResultsThe results showed that MXHQD alleviated the computed tomography (CT) and the pathological degree changes in mice with IPF, improved changes in the expression of fibrosis related genes and reduced the hydroxyproline expression in IPF mice. MXHQD also decreased the cell numbers in bronchoalveolar lavage fluids, and the expression levels of the inflammatory factors in the ALI mice lung tissues were significantly inhibited. By applying whole transcriptome analysis, results showed that MXHQD acted on 40 mRNAs, 15 miRNAs, 25 novel lncRNAs and 17 circRNAs to resist pulmonary fibrosis. The competing endogenous RNA (ceRNA) network diagram showed that the multiple components of MXHQD against fibrosis through a network of multiple targets. The differential mRNAs were mainly related to the innate immune response and the defense response to virus. Then the expression of mRNAs in the differential mRNA-miRNA-differential circRNA network in the lung tissue of IPF was verified. The expression of ZBP1 and ISG15 related to immune system and anti virus was verified at both gene and protein expressions. MXHQD could significantly inhibit the elevation of ZBP1 and ISG15 factors induced by the fibrosis model. ConclusionOverall, our findings provide compelling evidence that MXHQD can alleviate IPF by modulating innate immunity. This is the first study to reveal the molecular mechanism underlying the multi-components, multi-channels and multi-targets anti-IPF immune injury of MXHQD, and supports its potential clinical application for IPF.

The efficacy of traditional Chinese medicine in the treatment of the COVID-19 pandemic in Henan Province: a retrospective study

BackgroundSince 2020, novel coronavirus disease (COVID-19) has posed serious threats to health systems and led to tremendous economic decline worldwide. Traditional Chinese medicine (TCM) is considered a promising treatment strategy for COVID-19 in China and is increasingly recognized as a key participant in the battle against COVID-19. Clinicians also need accurate evidence regarding the effectiveness of TCM treatments for COVID-19.MethodsWe retrospectively analyzed patients diagnosed with COVID-19 by collected from the electronic medical records of the hospitals in Henan Province from January 19, 2020, to March 2, 2020. Demographic characteristics, clinical data, frequency analysis of Chinese patent medicines (CPMs), Chinese medicine injections (CMIs), evaluation of baseline symptom scores, nucleic acid negative conversion, length of hospitalization, and mortality rates were studied.ResultsBetween 15 January 2020 and 2 March 2020, 131 hospitals with 1245 patients were included. Survey response Chinese herbal decoction, CPMs, and CMIs combined with conventional Western medicine (CWM) used for the treatment of COVID-19. The top 8 CPMs were Lianhua Qingwen capsules, Shuanghuanglian oral liquid, Pudilan Xiaoyan oral liquid, Banlangen granules, Lanqin oral liquid, compound licorice tablets, Bailing capsules, montmorillonite powder. The most frequently used CMIs were Xuebijing, Tanreqing, Reduning, Xiyanping and Yanhuning. TCM combined with CWM improved the patients’ symptom scores for fever, cough, chest tightness, shortness of breath, and fatigue. Nucleic acid negative conversion occurred at11.55 ± 5.91 d and the average length of hospitalization was 14.92 ± 6.15 d. The mortality rate was approximately 1.76%, which is a reduction in patient mortality.ConclusionsTCM combined with CWM improved clinical symptoms and reduced hospitalization and mortality rates.

Investigation of Chinese Herbal Decoctions with Enzymatic Hydrolysis and Sequential Fermentation as Potential Nutrient Supplements

Chinese herbal medicine has attracted increasing attention due to its therapeutic effects. It demands increasing understanding of the processing methods and the generated changes to control quality and offer better final products. In this study, extraction differences were compared among direct plant extracts (DE), standard decoction (SD), spontaneous fermentation (SF) and inoculated sequential fermentation (IF). Results showed that the extraction with the transformation of probiotics positively contributed to the release of functional compounds from Chinese herbs. It provided the strongest antioxidant capacity and the best amino acid profile. The flavor and the compositions of the herbal decoctions were further characterized. Distinctive volatile differences were found, indicating that the different treatments profoundly altered the spectrum of volatile components. The most aromatic changes were in the IF group, which corresponded with the greatest number of upregulated and the lowest number of downregulated differential compounds. Beneficial intestinal microbiota with voluntary intake of herbal tea suggested a possible positive metabolism shift in the healthy host. In conclusion, the combination of enzymatic hydrolysis and sequential fermentation provided better extraction efficiency than direct plant extraction and traditional herbal decoction. It may enable a broader utilization of traditional Chinese herbs as potential nutrient supplements, such as antibiotic alternatives in animal husbandry.

Network pharmacology, molecular docking, and experimental verification reveal the mechanism of San-Huang decoction in treating acute kidney injury.

Background: Cisplatin is an effective anti-tumor drug. However, its usage is constrained by side effects such as nephron toxicity. Cisplatin-induced acute kidney injury (AKI) appears in approximately 20%-30% of cases. Hence, finding an effective protective strategy is necessary. San-Huang decoction (SHD) is a Chinese herbal decoction with good efficacy in treating chronic kidney disease (CKD). Nevertheless, the mechanism of SHD on AKI remains unclear. Consequently, we proposed to explore the potential mechanism of SHD against cisplatin-induced AKI. Methods: Active compounds, core target proteins, and associated signaling pathways of SHD were predicted through network pharmacology. Then confirmed by molecular docking. In vivo experiment, Cisplatin + SHD group was treated with SHD (6.5g/kg/day) for 6days before building the model. An AKI model was established with a single intraperitoneal injection of cisplatin at 20mg/kg. After 72h of cisplatin injection, all mice were sacrificed to collect blood and kidney tissues for verification of network pharmacology analysis. Results: We found that calycosin, rhein, and ginsenoside Rh2 may be SHD's primary active compounds in treating cisplatin-induced AKI, and AKT, TNF-α, IL-6, IL-1β, caspase-3, and MMP9 are the core target proteins. The relationship between the compound and target protein was further confirmed by molecular docking. The Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses predicted that SHD has an anti-inflammatory role through the TNF and IL-17 signaling pathway. Moreover, Western blot and immunohistochemistry validated the potential molecular mechanisms of SHD, predicted from network pharmacology analysis. The mechanism of cisplatin-induced AKI involves apoptosis and inflammation. In apoptosis, Caspase-3, caspase-8, caspase-9, and Bax proteins were down-regulated, while Bcl-2 was up-regulated by SHD. The differential expression of MMP protein is involved in the pathological process of AKI. MMP9 protects from glomerular tubule damage. MMP9 and PI3K/AKT anti-apoptosis pathway were up-regulated by SHD. In addition, we discovered that SHD alleviated AKI by inhibiting the NF-κB signaling pathway. Conclusion: SHD plays a critical role in anti-inflammation and anti-apoptosis via inhibiting the NF-κB signaling pathway and activating PI3K/AKT anti-apoptosis pathway, indicating that SHD is a candidate herbal drug for further investigation in treating cisplatin-induced AKI.

Exploring the mechanism of Chaihujia Longgu Muli decoction in the treatment of epilepsy in rats based on the RhoA/ROCK signaling pathway.

The Chinese herbal formula Chaihujia Longgu Muli Decoction (CD) has a good antiepileptic effect, but its mechanisms remain unclear. Therefore, in this study we explored the molecular mechanisms of CD against epilepsy. Twelve-day-old SD rats were randomly divided into a normal group, model group, valproic acid group, and CD high, medium, and low groups. Except for the normal group, the other groups were given an intraperitoneal injection of pentylenetetrazol (PTZ) to establish epilepsy models, and the Racine score was applied for model judgment. After 14 consecutive days of dosing, the Morris water maze test was performed. Then, hippocampal Nissl staining and immunofluorescence staining were performed, and synaptic ultrastructure was observed by transmission electron microscopy (TEM). RhoA/ROCK signaling pathway proteins were detected. In PTZ model rats, the passing times were reduced, and the escape latency was prolonged in the Morris water maze test. Nissl staining showed that some hippocampal neurons swelled and ruptured, Nissl bodies in the cytoplasm were significantly reduced, and neurons were lost. Immunofluorescence detection revealed that the expression of PSD95 and SYP was significantly reduced. Electron microscopy results revealed that the number of synapses in hippocampal neurons was significantly reduced and the postsynaptic membrane length was significantly reduced. Western blot analysis showed that the RhoA/ROCK signaling pathway was activated, while SYP, SPD95, and PTEN expression was significantly decreased. After treatment with CD, neurobehavioral abnormalities and neuronal damage caused by epileptic seizures were improved. CD exerted an antiepileptic effect by inhibiting the activation of the RhoA/ROCK signaling pathway.

A four-compound remedy AGILe protected H9c2 cardiomyocytes against oxygen glucose deprivation via targeting the TNF-α/NF-κB pathway: Implications for the therapy of myocardial infarction.

Myocardial infarction (MI) is a highly prevalent and lethal disease worldwide. Prevention and timely recovery are critical for the control of the recurrence and heart failure in MI survivors. The present study was designed to investigate the cardioprotective activity of the herbal medicine formula Baoyuan Decoction (BYD) and identify the active compounds and molecular targets. The ethanolic BYD extract (BYDE) was prepared by water extraction and ethanol precipitation of four herbal medicines, Astragali Radix, Ginseng Radix et Rhizoma, Cinnamomi Cortex, and Glycyrrhizae Radix et Rhizoma. Initially, BYDE was validated for the cardioprotective effectiveness in a mouse model of ischemia injury and rat cardiomyocyte H9C2 cells. As results, BYDE effectively reduced infarct size from 56% to 37% and preserved cardiac functions in mouse MI model while protected H9C2 cells against oxygen glucose deprivation. Subsequent network pharmacology analysis revealed that 122 bioactive ingredients, including flavonoids and saponins from the UPLC-MS/MS profile of BYDE, might target 37 MI-related proteins, including inflammatory and apoptotic mediators (e.g., TNF, NFKB1, CASPs, TNFRSF1A, CXCL12, BCL2A1). Pathway enrichment analysis suggested that BYDE might control the cardiac inflammation via targeting the tumor necrosis factor-alpha (TNF-α)/nuclear factor-κB (NF-κB) pathway while the selected targets were also implicated in IL-17 signaling pathway, lipid and atherosclerosis. Consequently, adenosine, ginsenoside Rh2, isoliquiritigenin, and licochalcone A were selected to generate the four-compound mixture AGILe and validated for the inhibitory effects on the TNF-α/NF-κB pathway. The results of the present study suggested that the mixture AGILe might be a potential cardioprotective remedy against MI.

Herbal formula Jiawei Xiaochengqi decoction prevents postoperative abdominal adhesion in a rat model through inhibition of CXCL2-CXCR2 pathway

BackgroundPostoperative abdominal adhesion (PAA) is the most common complication after abdominal surgeries, which can lead to intestinal obstruction, chronic abdominal pain or female infertility. Jiawei Xiaochengqi decoction (JWXCQ) is a hospital preparation widely used for PAA treatment in Nanfang Hospital of Southern Medical University for more than twenty years. PurposeThis study aimed to investigate the therapeutic effects and potential mechanism of JWXCQ against PAA and provide beneficial information for its clinical application. MethodsThe main active components of JWXCQ were identified using ultra high performance liquid chromatography (UHPLC) combined with standard substance comparison. The efficacy and underlying mechanism of JWXCQ were evaluated through in vivo experiments with a postsurgical-induced peritoneal adhesion rat model, and in vitro studies with LPS-stimulated Raw 264.7 macrophages and primary fibroblasts. H&E and Masson staining were performed to assess histopathological changes. The levels of cytokines/proteins-associated with inflammation and degradation of extracellular matrix as well as CXCL2-CXCR2 pathway-related proteins were determined by ELISA, qRT-PCR, western blot assays or immunohistochemistry, respectively. Furthermore, siCXCR2 transfection was used to validate the mechanism of action of JWXCQ. ResultsJWXCQ treatment significantly reduced the formation of PAA, inhibited the inflammation and collagen deposition, and facilitated the secretion of MMP9, decreased the levels of IL-1β, IL-6, TIMP1, COL-1, and suppressed the CXCL2-CXCR2 pathway in PAA rats. Furthermore, JWXCQ inhibited its downstream pathways, the JAK2-STAT3 and PI3K-AKT signaling, as indicated by the suppression of the phosphorylation levels of STAT3 and AKT. In vitro cell experiments revealed that JWXCQ reduced IL-1β and IL-6 secretion in Raw 264.7 macrophages and COL-1 in primary fibroblasts. The CXCL2-CXCR2, JAK2-STAT3 and PI3K-AKT pathways were also inhibited after JWXCQ treatment, which were consistent with the in vivo results. More importantly, silence of CXCR2 eliminated the regulatory effects of JWXCQ. ConclusionJWXCQ could effectively prevent the PAA formation by alleviating inflammation and collagen deposition, which was associated with the inhibition of CXCL2-CXCR2 pathway. This study investigated the relevant pharmacological mechanisms of JWXCQ, providing further evidence for the application of JWXCQ in clinical PAA treatment.

Investigating the Role of Classical Ayurveda-Based Incineration Process on the Synthesis of Zinc Oxide Based Jasada Bhasma Nanoparticles and Zn2+ Bioavailability.

Jasada bhasma (JB) is a zinc oxide-based Indian traditional Ayurveda-based herbo-metallic nanoparticle used for the treatment of zinc (Zn) deficiency and autoimmune and inflammatory disorders. JB is made by following the Ayurveda-based guidelines using zinc oxide (ZnO) as a raw material and going through 17 cycles of the high-temperature incineration and trituration process known as "Ma̅raṇa" in the presence of herbal decoctions prepared from the leaves ofAzadirachta indica andAloe vera gel. These cycles improve the purity of the parent material and transform its physicochemical properties, converting it into nanoparticles. However, there still exists a knowledge gap regarding the role of incineration in the physicochemical transformation of the Zn raw material into JB nanoparticles and the biological interaction of the final product. In the present study, the JB samples obtained during different Ma̅raṇa cycles were carefully studied for their physicochemical transformation using analytical methods such as powdered X-ray diffraction (XRD), small-angle X-ray scattering (SAXS), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy, Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and dynamic light scattering (DLS). According to the XRD results, the Zn and oxygen molecules in hexagonal ZnO wurtzite crystals gradually realigned as a result of repeated heat treatments that caused lattice tension and crystal size reduction from 53.14 to 42.40 nm. A morphological transition from 1.5 μm rod shape to 31 nm in the JB particles can be seen using FESEM and SAXS analyses. The existence of 10 nm-sized nanoparticles in the finished product was confirmed by HRTEM. The presence of ZnO was confirmed in all samples by FTIR and Raman spectroscopies. Cell viability analysis showed an inhibitory concentration 50% of >1000 μg/mL for JB nanoparticles, revealing no adverse effects in human colon Caco-2 cells. A dose-dependent uptake and intracellular accumulation of JB nanoparticles were observed in Caco-2 cells using inductively coupled plasma-based mass spectroscopy (ICP-MS). Bioavailability of Zn2+ ions (6% w/w) through JB dissolution in acidic pH 4.0 was observed, representing the stomach and intracellular lysosomal physiological conditions. Therefore, the study showed that the repeated incineration cycles produced biocompatible JB nanoparticles through the physicochemical transformation at molecular levels capable of delivering bioavailable Zn2+ ions under physiological conditions. In conclusion, the medicinal properties of JB nanoparticles described in Ayurveda were found to originate from their small size and dissolution properties, formed through the classical incineration-based synthesis process.

Observational Case Study on the Effectiveness of the Herbal Decoction Varanadi Kashaya in Managing Obesity of an Individual with Metabolic Disorders

Obesity is increasing globally generating serious non-communicable diseases. The antiobesity drugs in the market don’t have any impact on adipocytes; the root cause of obesity, but give rise to many side effects. Several clinical studies have shown the potential of Varanadi Kashaya (VK) mentioned in Ayurveda classic Ashtanga Hrudaya in suppressing adipogenesis and lipid accumulation favoring anti-obesity action without any side effects. Yet, the efficacy of VK in managing obesity in individuals with metabolic disorders has not been evaluated in detail. As the constituents of VK has hypocholesterolemic, anti-diabetic and antioxidant characteristics it can address metabolic disorders as well. This study aims to determine the efficacy of VK in an obese individual with metabolic disorders. Materials and Methods: VK was given for 30 days to an obese person with diabetes and hyperlipidemia and evaluated the changes in anthropometry, Ayurveda parameters and laboratory investigations. Results: High-risk apple shape body shifted into a ratio between apple and pear threshold; a moderate risk to health problems by reducing weight/hip ratio (0.95 to 0.84), LDL (112.6 mg/dl to 106.2 mg/dl), total cholesterol (180 mg/dl to 171 mg/dl) and Non-HDL levels (132 mg/dl to 129 mg/dl) Conclusion: VK has the potency to address both subcutaneous and visceral fat; reducing obesity and controlling obesity-related metabolic disorders.
