Biological network comparison identifies a novel synergistic mechanism of Ginseng Radix-Astragali Radix herb pair in cancer-related fatigue

Ethnopharmacological relevanceGinseng Radix and Astragali Radix are commonly combined to tonify Qi and alleviate fatigue. Previous studies have employed biological networks to investigate the mechanisms of herb pairs in treating different diseases. However, these studies have only elucidated a single network for each herb pair, without emphasizing the superiority of the herb combination over individual herbs. Aim of the studyThis study proposes an approach of comparing biological networks to highlight the synergistic effect of the pair in treating cancer-related fatigue (CRF). MethodsThe compounds and targets of Ginseng Radix, Astragali Radix, and CRF diseases were collected and predicted using different databases. Subsequently, the overlapping targets between herbs and disease were imported into the STRING and DAVID tools to build protein-protein interaction (PPI) networks and analyze enriched KEGG pathways. The biological networks of Ginseng Radix and Astragali Radix were compared separately or together using the DyNet application. Molecular docking was used to verify the predicted results. Further, in vitro experiments were conducted to validate the synergistic pathways identified in in silico studies. ResultsIn the PPI network comparison, the combination created 89 new interactions and an increased average degree (11.260) when compared to single herbs (10.296 and 9.394). The new interactions concentrated on HRAS, STAT3, JUN, and IL6. The topological analysis identified 20 core targets of the combination, including three Ginseng Radix-specific targets, three Astragali Radix-specific targets, and 14 shared targets. In KEGG enrichment analysis, the combination regulated additional signaling pathways (152) more than Ginseng Radix (146) and Astragali Radix (134) alone. The targets of the herb pair synergistically regulated cancer pathways, specifically hypoxia-inducible factor 1 (HIF-1) signaling pathway. In vitro experiments including enzyme-linked immunosorbent assay and Western blot demonstrated that two herbs combination could up-regulate HIF-1α signaling pathway at different combined concentrations compared to either single herb alone. ConclusionThe herb pair increased protein interactions and adjusted metabolic pathways more than single herbs. This study provides insights into the combination of Ginseng Radix and Astragali Radix in clinical practice.

A Traditional Chinese Medicine, Zhenqi Granule, Potentially Alleviates Dextran Sulfate Sodium-Induced Mouse Colitis Symptoms.

Ulcerative colitis (UC) is an inflammatory bowel disease that causes chronic inflammation in the large intestine. The etiology of UC is complex and incompletely understood, with potential contributing factors including genetic susceptibility, environmental influences, immune dysregulation, and gut barrier dysfunction. Despite available therapeutic drugs, the suboptimal cure rate for UC emphasizes the necessity of developing novel therapeutics. Traditional Chinese Medicine (TCM) has attracted great interest in the treatment of such chronic inflammatory diseases due to its advantages, such as multi-targets and low side effects. In this study, a mouse model of Dextran Sulfate Sodium (DSS)-induced acute colitis was established and the efficacy of Zhenqi Granule, a TCM preparation composed of the extractives from Astragali Radix and Fructus Ligustri Lucidi, was evaluated. The results showed that treatment with Zhenqi Granule prior to or post-DSS induction could alleviate the symptoms of colitis, including weight loss, diarrhea, hematochezia, colon length shortening, and pathological damage of colon tissues of the DSS-treated mice. Further, network pharmacology analysis showed that there were 98 common targets between the active components of Zhenqi Granule and the targets of UC, and the common targets were involved in the regulation of inflammatory signaling pathways. Our results showed that Zhenqi Granule had preventive and therapeutic effects on acute colitis in mice, and the mechanism may be that the active components of Zhenqi Granule participated in the regulation of inflammatory response. This study provided data reference for further exploring the mechanism of Zhenqi Granule and also provided potential treatment strategies for UC.

Prescription Data Mining and Network Pharmacology Study of 1152 Patients with Rectal Prolapse Using Traditional Chinese Medicine.

In recent years, the incidence of rectal prolapse has increased significantly due to the sedentary lifestyle and irregular eating habits of modern life. However, there is a lack of clinical studies on the treatment of rectal prolapse with traditional Chinese medicine (TCM) with a large sample size. Therefore, this study investigated the characteristics of rectal prolapse treatment formulas and then studied the network pharmacology of their core therapeutic drugs, which can help to provide a reference for the treatment and postoperative care of rectal prolapse patients. This study aimed to explore the prescription characteristics and the mechanism of action of core drugs in the treatment of rectal prolapse in Chinese medicine through data mining and bioinformatics techniques. We collected the diagnosis and treatment information of patients with rectal prolapse from January 2014 to September 2021 in the electronic case database of Nanjing Hospital of TCM, mined the patient information and prescription features using R, screened the active ingredients of the core pairs of drugs and disease drug intersection targets using TCMSP and GnenCard databases, and constructed a Protein-protein interaction (PPI) network using STRING and Cytoscape, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of the intersecting targets were performed using Metascape and R. We found that prolapse is easy to occur in people over 50 years old, preferably in autumn and winter. Commonly used therapeutic Chinese medicines include Glycyrrhiza glabra, Radix angelicae sinensis, Radix astragali, Atractylodes macrocephala, and Pericarpium citri reticulatae, which are mostly deficiency tonic medicines, warm in nature, and belong to spleen meridian. The core therapeutic medicinal pair was "Bupleuri radix-Cimicifugae rhizoma". There were 190 common targets of Bupleuri radix and Cimicifugae rhizoma, and 71 intersection targets of the drug pair and prolapse. The main components of the core drugs for the treatment of prolapse may be quercetin, kaempferol, Stigmasterol, etc, and the core targets may be CASP3, AKT1, HIF1A, etc. The total number of GO entries for the intersection targets of "Bupleuri radix-Cimicifugae rhizoma" and diseases was 3495, among which the molecular functions accounted for the largest proportion, mainly Pathways in cancer, IL-18 signaling pathway, etc. KEGG enriched pathway analysis yielded 168 results, and the major pathways were pathways in cancer, lipid and atherosclerosis, IL-17 signaling pathway, etc. Conclusion: This study adopted real-world research methodology and used data mining and bioinformatics technology to mine the medication law of rectal prolapse and its core drug action mechanism from the clinical information of Chinese medicine.

A Rapid and Accurate UHPLC Method for Determination of Monosaccharides in Polysaccharides of Different Sources of Radix Astragali and Its Immune Activity Analysis.

With the escalating demand for Astragalus polysaccharides products developed from Radix Astragali (RA), the necessity for quality control of polysaccharides in RA has become increasingly urgent. In this study, a specific method for the simultaneous determination of seven monosaccharides in polysaccharides extracted from Radix Astragali (RA) has been developed and validated using ultra-performance liquid chromatography equipped with an ultraviolet detector (UHPLC-UV) for the first time. The 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatizations were separated on a C18 column (Waters ACQUITYTM, Milfor, MA, USA, 1.8 µm, 2.1 × 100 mm) using gradient elution with a binary system of 5 mm ammonium formate (0.1% formic acid)-acetonitrile for 24 min. Additionally, seven monosaccharides showed good linear relationships (R2, 0.9971-0.9995), adequate precision (RSD < 4.21%), and high recoveries (RSD < 4.70%). The established method was used to analyze 109 batches of RA. Results showed that the Astragalus polysaccharides (APSs) mainly consist of mannose (Man), rhamnose (Rha), glucose (Glu), galactose (Gal), arabinose (Ara), xylose (Xyl); and fucose (Fuc); however, their composition was different among RA samples from different growth patterns, species, growth years, and origins, and the growth mode of RA and the age of wild-simulated RA can be accurately distinguished by principal component analysis (PCA). In addition, the immunological activity of APSs were also evaluated jointly by measurement of the NO release with RAW264.7, with the results showing that APSs have a promoting effect on the release of NO and exhibit a significant correlation with Man, Glu, Xyl, and Fuc contents. Accordingly, the new established monosaccharides analytical method and APS-immune activity determination in this study can provide a reference for quality evaluation and the establishment of quality standards for RA.

Potential mechanisms of formononetin against inflammation and oxidative stress: a review.

Formononetin (FMNT) is a secondary metabolite of flavonoids abundant in legumes and graminaceous plants such as Astragalus mongholicus Bunge [Fabaceae; Astragali radix] and Avena sativa L. [Poaceae]. Astragalus is traditionally used in Asia countries such as China, Korea and Mongolia to treat inflammatory diseases, immune disorders and cancers. In recent years, inflammation and oxidative stress have been found to be associated with many diseases. A large number of pharmacological studies have shown that FMNT, an important bioactive metabolite of Astragalus, has a profoundly anti-inflammatory and antioxidant potential. This review focuses on providing comprehensive and up-to-date findings on the efficacy of the molecular targets and mechanisms involve of FMNT and its derivatives against inflammation and oxidative stress in both in vitro and in vivo. Relevant literature on FMNT against inflammation and oxidative stress between 2013 and 2023 were analyzed. FMNT has antioxidant and anti-inflammatory potential and shows mild or no toxicity in various diseases. Moreover, in the medical field, FMNT has shown potential in the prevention and treatment of cancers, neurological diseases, fibrotic diseases, allergic diseases, metabolic diseases, cardiovascular diseases, gastrointestinal diseases and autoimmune diseases. Thus, it is expected to be utilized in more products in the medical, food and cosmetic industries in the future.

Clinical remission of moderate generalized myasthenia gravis through exclusive use of Buzhong Yiqi decoction: A case report

BackgroundMyasthenia gravis (MG) is a rare autoimmune neuromuscular disorder with significant morbidity and mortality. Traditional Chinese medicine (TCM) offers an alternative approach to standard pharmacological and surgical interventions, which are often associated with adverse side effects. This case report details the clinical remission of a 50-year-old male with moderate generalized MG following exclusive treatment with a modified Buzhong Yiqi decoction (BYD), a TCM formula, without the use of immunosuppressive agents. Case summaryThe patient presented with diplopia, bilateral ptosis, weakness in chewing, limb weakness, and other symptoms indicative of spleen and stomach qi deficiency. Modified BYD was prescribed, focusing on strengthening the spleen, nourishing qi and blood, and enhancing immune response. The treatment included ingredients such as Radix Astragali, Angelica sinensis, Atractylodes macrocephala, and others, aiming to restore balance and improve the patient's condition. After two weeks of TCM treatment, the patient showed significant improvement in symptoms of myasthenia. By the second month, all clinical symptoms had disappeared. The patient continued to receive the TCM regimen until the thirtieth month of treatment. At the time of writing this report, the patient has no clinical symptoms and has experienced no relapse. Notably, no obvious adverse effects were reported throughout the treatment. ConclusionThe success of this case suggests that TCM may serve as an independent treatment option for moderate MG, offering a steroid-free alternative, which would be particularly valuable for patients who are intolerant of or refuse steroid therapy, potentially with significant clinical implications. However it needs a randomized clinical trial comparing TCM to conventional Western medicine treatment to validate it.

Active substances and molecular mechanisms of Astragali Radix and Angelicae Sinensis radix against idiopathic pulmonary fibrosis effects by network pharmacology and in vitro experiments

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive fibrotic disease with an unclear etiology and no effective treatment. This study aims to elucidate the pathogenic mechanism networks involving multiple targets and pathways in IPF. Extracts and metabolites of Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), two well-known traditional Chinese medicines, have demonstrated therapeutic effects on IPF. However, the underlying mechanisms of AR and ASR remain unclear. Utilizing network pharmacology analysis, the disease targets associated with IPF were obtained from the GeneCards database and Online Mendelian Inheritance in Man (OMIM) database. Targets of AR and ASR were identified using the Traditional Chinese Medicine (TCM) Systems Pharmacology Database and Analysis Platform and Swiss Target Prediction. A proteinprotein interaction (PPI) network was subsequently constructed and analyzed using the STRING database and Cytoscape software. Gene ontology enrichment (GO) analysis and kyoto encyclopedia of genes and genomes (KEGG) analysis were conducted using DAVID. Additionally, a component-target-pathway network was employed to identify the main active components, and molecular docking was performed between these components and proteins encoded by key targets. Finally, in vitro studies were conducted based on network pharmacology. A total of 260 common targets between IPF and drug targets were identified and included in the PPI network, in which TNF, IL-6, STAT3, AKT1, VEGFA, SRC, EGFR, INS, JUN, and IL1B were predicted as key targets. These 260 targets were enriched in the PI3K-AKT signaling pathway, HIF-1 signaling pathway, TNF signaling pathway, MAPK signaling pathway, FOXO signaling pathway, and Pathways in cancer. Docking scores ranged from –4.1 to –9.5 kcal/mol, indicating a strong binding affinity between the main active compounds and key targets. In vitro studies have indeed shown that Quercetin and Magnolol can alleviate the expression of epithelial-mesenchymal transition in the A549 cells caused by IL-6. The treatment with AR and ASR resulted in a reduction of mRNA levels for key targets HIF-1α and α-SAM. Additionally, the protein expression levels of P-JAK2/JAK2, P-STAT3/STAT3, and α-SMA/β-Actin were also reduced. These results support the therapeutic potential of AR and ASR in ameliorating pulmonary fibrosis and provide insight into the molecular mechanisms involved in their therapeutic effects.

Mechanism and compatibility efficacy of Astragali Radix-Chuanxiong Rhizoma drug pair in treating ischemic stroke based on network regulation

Based on the association network of &quot;drug pair-disease&quot;, the effect characteristics of Astragali Radix-Chuanxiong Rhizoma drug pair in the treatment of ischemic stroke(IS) with Qi deficiency and blood stasis and the matching mechanism of the two were explored. Through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction Database, the effective chemical components of the drug pair were screened, and the candidate targets were predicted. Databa-ses such as GeneCards, DrugBank, Online Mendelian Inheritance in Man(OMIM), and Therapeutic Target Database(TTD) were searched to obtain gene targets related to IS. Through STRING and Cytoscape 3.9.1 software, the protein-protein interaction(PPI) network was constructed by using the interaction information of disease syndrome-related genes and candidate targets of drug pairs, and the core targets were screened according to the network topological feature values. Based on the Metascape platform and DAVID database, the biomolecular interaction information was integrated to analyze the Kyoto Encyclopedia of Genes and Genomes(KEGG) and mine biological functions, so as to further explore the mechanism of action and compatibility characteristics of Astragali Radix-Chuan-xiong Rhizoma. The results showed that the candidate biological process was mainly involved in the regulation of functional modules such as immune, blood circulation, neurotransmitter, and oxidative stress, and it was enriched in lipid and atherosclerosis, calcium signaling pathway, and platelet activation. Astragali Radix and Chuanxiong Rhizoma have their own characteristics. Astragali Radix has a regulatory response to growth factors while maintaining the body's immune balance, while Chuanxiong Rhizoma mainly improves the circulatory system and participates in hormone metabolism, so as to indicate the compatibility mechanism of Astragali Radix-Chuanxiong Rhizoma drug pair for multi-target and multi-pathway synergistic treatment of IS. Through further experimental verification, it was found that the Astragali Radix-Chuanxiong Rhizoma drug pair could significantly down-regulate the expression of key targets including TLR4, NF-κB, IL-1β, F2R, PLCβ1, and MYLK. This study preliminarily reveals that the Astragali Radix-Chuanxiong Rhizoma drug pair may play the three replenishing effects of promoting blood circulation, benefiting Qi, and clearing collaterals by correcting immune di-sorders, blood circulation disorders, and inflammation, which provide support for the clinical research on the subsequent improvement of Qi deficiency and blood stasis in the treatment of IS and provide a new idea for the analysis of modern biological connotation of the compatibility of seven emotions of traditional Chinese medicine.

Astragaloside IV inhibits colorectal cancer metastasis by reducing extracellular vesicles release and suppressing M2-type TAMs activation

Ethnopharmacological relevanceTumour-derived extracellular vesicles (TEVs) have been confirmed to facilitate colorectal cancer (CRC) metastasis by remodelling the tumour microenvironment (TME). Drugs targeted TEVs is considered as a promising therapeutic strategy for cancer treatment. Traditional Chinese medicine (TCM) plays a vital role in improving the prognosis of CRC patients and eventually CRC patients with distant metastasis. Although the anti-tumour effects of active compounds from TCM prescriptions are observed widely, the molecular mechanisms remain unknown. Aim of the studyThis study aims to investigate the effects of active compounds in our library of TCM on preventing CRC metastasis, and also explore the potential mechanisms from the perspective of TEVs. Materials and methods: The effects of active compounds on the proliferation of CRC cells were determined by CCK-8 assay. TEVs were extracted from MC38 cells by ultracentrifugation and characterized by electron microscopy, Nanosight NS300 and western blotting. The TEV particles were quantified by Nanosight NS300. The potential mechanism by which astragaloside IV (ASIV) reduced TEV secretion was determined by western blotting. RAW264.7 cells were cocultured with the conditioned medium (CM) of MC38 cells treated with or without ASIV, and the activation of tumour-associated macrophages (TAMs) was assessed by immunofluorescence and quantitative polymerase chain reaction (qPCR). The migration of CRC cells was measured by wound healing and Transwell assay. A spleen-to-liver metastasis model of colorectal cancer was used to confirm the efficiency of ASIV in vivo. Liver metastatic tumours of the mice were used for liver weight measures and H&E staining. Immunofluorescence was applied to observe the infiltration of TAMs, the expression of neutral sphingomyelinase 2 (nSMase2) and Rab27a. ResultsBy screening our TCM monomer library, we found that ASIV, which is mainly extracted from Radix Astragali, reduced the release of TEVs from CRC cells in a time- and concentration-dependent manner. Mechanistically, ASIV inhibited the production and secretion of TEVs by downregulating nSMase2 and Rab27a expression in CRC cells. CM from ASIV-treated CRC cells reshaped the polarization of TAMs by decreasing M2-type polarization, increasing M1-type polarization. Consequently, the repolarization of M2-type to M1-type macrophages led to reduced invasion and migration of CRC cells. Moreover, we confirmed that ASIV inhibited the liver metastasis of CRC, reduced M2-type macrophage infiltration and decreased the expression of nSMase2 and Rab27a in liver metastases. ConclusionsASIV inhibited CRC metastasis by reducing EVs release and suppressing M2-type TAMs activation. All these findings reveal a new insight into the mechanisms of ASIV in preventing CRC progression and provide a promising approach for anti-tumour therapy.

Integrated metabolomics and transcriptomics to study mechanisms of Paecilomyces cicadae-fermented Radix astragali in the treatment of hyperuricemia

The prevalence of hyperuricemia (HUA) is rising annually due to societal growth and changes in lifestyle. Bidirectional solid-state fermentation of substrates has demonstrated encouraging uses in the clinical treatment of HUA. To investigate the powerful therapeutic potential of solid-state fermentation products of Radix astragali and Paecilomyces cicadidae (RPF), multi-omics analysis was applied. Spearman analysis between serum biomarkers and differential expressed genes (DEGs) was used to estimate the potential mechanism of RPF against HUA, which was induced by high purine diet (HPD) and potassium oxonate. This study found that the serum uric acid, triglycerides, glucose, and creatinine level were decreased in HUA rats after RPF treatment. In addition, RPF effectively attenuated renal inflammation and lipid accumulation in the livers. Untargeted metabolomics and transcriptome sequencing technology demonstrated that the pathway regulated by RPF were “caffeine metabolism”, “fatty acid biosynthesis”, and “AMPK signaling”. Moreover, the correlation demonstrated that metabolites (allantoin, pyridoxamine, cytidine, cortodoxone, corticostrone) and DEGs (Phald3, Ccdc80) showed significantly positive correlations under RPF influence. Overall, findings of current study indicated the interactions between serum metabolites and renal genes. In line with these findings, the mechanism of the anti-HUA effect of RPF was revealed. In summary, the current study suggest pharmacological support for treating HUA with RPF.

Anti-osteoporotic effects of Yi Mai Jian on bone metabolism of ovariectomized rats.

Yi Mai Jian herbal formula (YMJ) is formulated with Eucommiae Folium, Astragali Radix, Ligustri Lucidi Fructus, and Elaeagnus Fructus to improve bone function in traditional Chinese medicine. The anti-osteoporotic effects of YMJ in bone metabolism were evaluated in ovariectomized (OVX) rats. The skeletal structure of the femur and vertebrae was analyzed after treating OVX rats with YMJ for 114days. The results showed that YMJ significantly increased the bone mineral density (BMD) and trabecular number (Tb. N) of the femur and 5th lumbar vertebrae and reduced trabecular separation (Tb. Sp). Moreover, trabecular bone volume/total tissue volume (BV/TV), bone stiffness, and maximum femur load were significantly increased. The serum concentrations of NTX1 and PYD were significantly decreased. According to these results, YMJ could ameliorate osteoporosis in ovariectomized rats. Eucommiae Folium and Elaeagnus Fructus inhibited osteoclast differentiation, Ligustri Lucidi Fructus inhibited calcium reabsorption, Astragali Radix stimulated osteoblast proliferation, and Astragali Radix and Eucommiae Folium stimulated mineralization. Therefore, the combination of the four herbs into one formula, YMJ, could alleviate bone remodeling caused by low estrogen levels. We suggest that YMJ could be a healthy food candidate for preventing post-menopausal osteoporosis.

Exploring the effects of calycosin on anthracycline-induced cardiotoxicity: a network pharmacology, molecular docking, and experimental study.

Chemotherapy with anthracyclines can cause cardiotoxicity, possibly leading to stopping treatment in some cancer patients. In cardio-oncology research, preventing and minimizing anthracycline-induced cardiotoxicity (AIC) is a hot issue. For the treatment of AIC, calycosin (CA), an isoflavone component in astragali radix (AR), has become a research focus. However, the elaborate mechanisms of calycosin treating AIC remain to be unrevealed. To explore the effects of CA on AIC through multiple dimensions concerning network pharmacology, molecular docking, and experimental evaluations. The study evaluated calycosin's potential targets and mechanisms for treating AIC using network pharmacology and molecular docking. The candidate genes/targets of CA and AIC were screened using the online-available database. Protein-protein interactions (PPI) between the common targets were constructed using the STRING platform, and the results were then visualized using Cytoscape. Molecular docking was used to evaluate the strength of the binding force between CA and the common targets. The possible pharmacological mechanisms of CA were explained by pathway enrichment and GSEA. Subsequently, the candidate targets were identified in vitro experiments. Network pharmacology effectively discovered the CA's multitarget intervention in AIC, including TNF, ABCC1, TOP2A, ABCB1, and XDH. CA binds to the ATP-binding cassette subfamily B member 1(ABCB1) had the highest binding energy (-7.5 kcal/mol) according to the molecular docking analysis and was selected and visualized for subsequent analysis. In vitro experiments showed that ABCB1 exhibited significant time-curve changes under different doses of doxorubicin (DOX) compared with DMSO control experiments. The anti-AIC pharmacological mechanism of CA were revealed by highlighting the biological processes of oxidative stress (OR) and inflammation. We employed a practicable bioinformatics method to connect network and molecular docking to determine the calycosin's therapeutic mechanism against AIC and identified some bioinformatics results in in vitro experiments. The results presented show that CA may represent an encouraging treatment for AIC.

Calycosin (CA) inhibits proliferation, migration and invasion by suppression of CXCL10 signaling pathway in glioma.

Glioblastoma is the most common malignant tumor in the central nervous system and its occurrence and development is involved in various molecular abnormalities. C-X-C chemokine ligand 10 (CXCL10), an inflammatory chemokine, has been reported to be related to the pathogenesis of cancer while it has not yet been linked to glioma. Calycosin, a bioactive compound derived from Radix astragali, has demonstrated anticancer properties in several malignancies, including glioma. Nonetheless, its underlying mechanisms are not fully understood. This study explores CXCL10 as a potential therapeutic target for calycosin in the suppression of glioblastoma. We observed that CXCL10 expression correlates positively with glioma malignancy and inversely with patient prognosis, highlighting its potential as a glioblastoma treatment target. Furthermore, we found that calycosin inhibited proliferation, migration, and invasion in U87 and U251 glioma cells, and decreased CXCL10 expression in a dose-dependent manner, along with its downstream effectors such as NLRP3, NF-κB, and IL-1β. Additionally, molecular docking experiments demonstrated that calycosin exhibits a notable binding affinity to CXCL10. Overexpression of CXCL10 counteracted the inhibitory effects of calycosin on cell proliferation, migration, and invasion, while CXCL10 knockdown enhanced these effects. Finally, we verified that calycosin inhibited glioma growth in a xenograft mouse model and downregulated CXCL10 and its downstream molecules. These findings suggest that targeting CXCL10 may be an effective strategy in glioblastoma treatment, and calycosin emerges as a potential therapeutic agent.

Effects of Designed Herbal Formula on Growth Performance, Blood Indices, Organ Traits, and Cecum Microbiology in Broilers.

The objective of this study was to investigate the effect of the designed herbal formula (DHF) on growth performance, blood indices, organ traits, and cecum microbiology in broilers. A total of 96 male broilers of 1 d were selected and randomly assigned to two groups with six replicates of eight broilers each. The control (CON) and the basal diet containing 1.0% DHF (Astragali radix, Atractylodes macrocephala Koidz., Isatis tinctoria Linnaeus, and Citri reticulatae pericarpium, 2:1:1:2) were fed separately. The experiment was conducted for 35 days. The results showed that the DHF diet increased body weight and decreased the feed conversion ratio (FCR) (p < 0.05). At 21 days, the spleen, thymus, lymphocytes, and thrombocytes were increased (p < 0.05), and pancreas, duodenum, heterophils, and mean corpuscular hemoglobin (MCH) were decreased (p < 0.05). At 35 days, the heart, pancreas, white blood cell, heterophils, hemoglobin, MCH and mean corpuscular hemoglobin concentration (MCHC) were decreased, while lymphocytes and middle cells were increased (p < 0.05). The results of microbial diversity analysis showed that the DHF diet decreased the microbial diversity of the cecum. Firmicutes and Bacteroidetes were the dominant phyla, where the DHF diet increased the relative abundances of Bacteroides uniformis, Bacteroides vulgatus, and Faecalibacterium prausnitzii, and then decreased the relative abundance of Shigella sonnei. In conclusion, DHF played a positive role in improving the growth performance, immune performance, and relative abundance of Bacteroides uniformis, Bacteroides vulgatus, and Faecalibacterium prausnitzii in cecum microbiology in broilers, and has the potential to be used as a novel feed additive.

Pharmacodynamics and Mechanism of Astragali Radix and Anemarrhenae Rhizoma in Treating Chronic Heart Failure by Inhibiting Complement Activation.

Astragali radix (AR) and anemarrhenae rhizoma (AAR) are used clinically in Chinese medicine for the treatment of chronic heart failure (CHF), but the exact therapeutic mechanism is unclear. In this study, a total of 60 male C57BL/6 mice were divided into 5 groups, namely sham, model, AR, AAR, and AR-AAR. In the sham group, the chest was opened without ligation. In the other groups, the chest was opened and the transverse aorta was ligated to construct the transverse aortic constriction model. After 8 weeks of feeding, mice were given medicines by gavage for 4 weeks. Left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were detected by echocardiography. Heart weight index (HWI) and wheat germ agglutinin staining were used to evaluate cardiac hypertrophy. Hematoxylin-eosin staining was used to observe the pathological morphology of myocardial tissue. Masson staining was used to evaluate myocardial fibrosis. The content of serum brain natriuretic peptide (BNP) was detected by enzyme-linked immunosorbent assay kit. The content of serum immunoglobulin G (IgG) was detected by immunoturbidimetry. The mechanism of AR-AAR in the treatment of CHF was explored by proteomics. Western blot was used to detect the protein expressions of complement component 1s (C1s), complement component 9 (C9), and terminal complement complex 5b-9 (C5b-9). The results show that AR-AAR inhibits the expression of complement proteins C1s, C9, and C5b-9 by inhibiting the production of IgG antibodies from B cell activation, which further inhibits the complement activation, attenuates myocardial fibrosis, reduces HWI and cardiomyocyte cross-sectional area, improves cardiomyocyte injury, reduces serum BNP release, elevates LVEF and LVFS, improves cardiac function, and exerts myocardial protection.

The official type of raw material included in the 7th edition of the European Pharmacopoeia is Radix Astragali – the dried root of Astragalus membranaceus (Fisch.) Bunge and Astragalus mongholicus Bunge. Extracts obtained from astragalus root have anti-inflammatory, immunostimulatory, antioxidant, diuretic effects. In traditional medicine, the herb of Astragalus dasyanthus Pall. is actively used. An infusion of the herb of Astragali dasyanthi has sedative, hypotensive and diuretic effects. However, the raw material is not official and is not included in the list of plant raw materials of the State Pharmacopoeia of the Russian Federation of the XIV edition. Promising species of the genus Astragalus L. can be not Astragalus membranaceus (Fisch.) Bunge and Astragalus dasyanthus Pall., but also other species, for example, Astragalus varius S.G. Gmel., Astragalus testiculatus Pall., Astragalus henningii (Stev.) Klok., which are widespread in the Saratov region. In view of the available data on the presence of the herb of Astragalus dasyanthus Pall. and Astragalus membranaceus (Fisch.) Bunge of the diuretic effect, it is of interest to study the diuresis of extracts from the herb of other species of the genus Astragalus L.Aim. To study the diuretic activity of infusions from the herb of four types of astragalus: Astragalus dasyanthus, Astragalus varius, Astragalus testiculatus, Astragalus henningii in 4- and 24-hour experiments on male rats.Materials and methods. The study of the diuretic activity of aqueous extracts from the herb of four types of Astragalus was performed on 42 white male rats, which were divided into 6 experimental and control groups of 6 animals. Aqueous extracts from Astragalus herb were prepared in the ratio of raw material-extractant 1:10, all obtained infusions met the requirements for these dosage forms according to the General Pharmacopoeia of the State Fund of the Russian Federation of the XIV edition. Aqueous extracts were administered to animals intragastrically through an umbrella at a dose of 100 mg/kg. During the experiment were collected 4-hour and 24-hour portions of urine. The comparison drug in the 4-hour experiment was furosemide at a dose of 1 mg/kg, and in the 24-hour experiment, hydrochlorothiazide at a dose of 20 mg/kg. Results and discussion. As a result of the experiment, the diuretic effect of the infusion of the herb of Astragalus dasyanthus both in the 4-hour experiment and in the 24-hour experiment. Also in both experiments, the most pronounced diuretic effect was found in the infusion of the herb of Astragalus henningii at a dose of 100 mg/kg compared with herb infusions Astragalus dasyanthus, Astragalus varius. Diuretic effect Astragalus henningii exceeded the diuretic activity of furosemide at a dose of 1 mg/kg, while a comparable effect was observed with hydrochlorothiazide at a dose of 20 mg/kg. Diuretic effect of herbal infusion Astragalus varius in a 4-hour experiment exceeded the diuretic effect of herb infusion Astragalus dasyanthus and furosemide at a dose of 1 mg/kg, and in a 24-hour experiment comparable to the diuretic effect of herb infusion Astragalus dasyanthus, but lower than that of hydrochlorothiazide at a dose of 20 mg/kg and herb infusion Astragalus henningii. Diuretic effect of herbal infusion Astragalus testiculatus at a dose of 100 mg/kg was not detected both in the 4-hour and in the 24-hour period. The diuretic activity of the group that received the infusion of the herb of Astragalus testiculatus was at the level of the control group, compared with other experimental groups, a statistically significant decrease in diuresis was observed in animals.Conclusion. The experiment confirmed the diuretic effect of the infusion of the herb of Astragalus dasyanthus and for the first time discovered the diuretic effect of the infusion of the herb of Astragalus varius and the infusion of the herb of Astragalus henningii. Among the studied infusions, the most pronounced diuretic effect was observed in Astragalus henningii herb infusion. The diuretic effect of Astragalus varius infusion is higher than that of Astragalus dasyanthus infusion. in a 4-hour experiment and did not differ in effectiveness from the infusion of the herb of Astragalus dasyanthus in a 24 hour experiment. The diuretic effect of the infusion of the herb astragalus oviparous was not revealed.

The effect of Jian Gan powder on the proliferation, migration and polarization of macrophages and relative mechanism

Context Jian Gan powder (JGP) is a Chinese medicine compound comprised ginseng, Radix Paeoniae Alba, Radix Astragali, Salvia miltiorrhiza, Yujin, Rhizoma Cyperi, Fructus aurantii, Sophora flavescens, Yinchen, Bupleurum and licorice. Objective This study explored the inhibitory effects, polarization and potential mechanisms associated with JGP in macrophages. Materials and methods RAW264.7 cells were randomly divided into six groups for 24 h: control, lipopolysaccharide (LPS), overexpression, 1% JGP, 2% JGP, 4% JGP, 8% JGP and 16% JGP. The effects of JGP on RAW264.7 cell proliferation were assessed using colony formation assays and cell counting kit-8 (CCK-8) assays. The Transwell assay was used to evaluate its impact on RAW264.7 cell migration. Moreover, we analysed the interleukin-6 (IL-6)/signal transducer and activator of the transcription 3 (IL-6/STAT3) signaling pathway using quantitative real-time PCR and Western blotting. Furthermore, we examined the M1/M2 polarization levels. Results Unlike LPS stimulation, JGP serum treatment markedly suppressed macrophage proliferation and migration capacity, while STAT3 overexpression enhanced RAW264.7 cell proliferation and migration. JGP inhibited the proliferation and migration of RAW264.7 cells by attenuating the IL-6/STAT3 signaling pathway. Furthermore, it inhibited macrophage M1 polarization, promoting M2 polarization. Discussion and conclusions JGP effectively suppressed the cellular function of RAW264.7 cells by down-regulating the IL-6/STAT3 signaling pathway and modulating macrophage M1/M2 polarization. These findings provide valuable theoretical and experimental basis for considering the potential clinical application of JGP in the treatment of immune-mediated liver injury in clinical practice.
