RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Angelica sinensis (AS) and Chuanxiong rhizoma (CR) are frequently prescribed in clinical settings for their ability to enrich blood, regulate menstrual cycles, and alleviate pain. Despite their widespread use, there is a relative dearth of studies exploring their anti-inflammatory properties. AIM OF THE STUDY: To evaluate the antioxidant and anti-inflammatory effects of Angelica sinensis-Chuanxiong rhizoma (ASCR) extracts and investigate its anti-inflammatory mechanisms. MATERIALS AND METHODS: AS and CR were combined in six ratios and extracted using five solvents. The quality of the resulting ASCR extracts was assessed by determining the content of ferulic acid (FA) using HPLC. The antioxidant effects of the ASCR extracts were evaluated in vitro using the DPPH and ABTS assays, as well as in HUVECs exposed to H2O2-induced oxidative damage. Additionally, the anti-inflammatory effects of the extracts were investigated in vivo through the assays of ear edema in mice and paw edema in rats. Biochemical markers including NO, MDA, and SOD in paw tissues, as well as PGE2, TNF-α, and COX-2 in rat serum, were measured to further elucidate the anti-inflammatory mechanisms of ASCR extracts. RESULTS: The WA-2-1 was obtained by combining AS and CR in a 2:1 ratio through first water then ethanol extraction, and showed favorable antioxidant and anti-inflammatory activities. The extract demonstrated effective scavenging abilities against DPPH⢠and ABTS+⢠radicals while also protecting against H2O2-induced oxidative damage. Furthermore, in vivo studies revealed that WA-2-1 had significant inhibitory effects on ear and paw edema as well as the ability to decrease NO and MDA levels, enhance SOD activity, and downregulate the expression of COX-2, PGE2, and TNF-α. CONCLUSIONS: The combination of AS and CR exhibits favorable anti-inflammatory effects, attributed to its dual actions of mitigating oxidative stress and suppressing the production of inflammatory mediators in serum or tissues during the inflammatory process.

Herbal medicine pair, composed of two single herbs, is a relatively fixed minimum prescription unit in the traditional Chinese medicine's formula and has special significance in clinic. The combination of Xiangfu (the rhizoma of Cyperus rotundus L, XF) and Chuanxiong (the rhizoma of Ligusticum chuanxiong Hort, CX) has been recoded as an herbal medicine pair XF-CX in the Yuan Dynasty (1347 CE) of China and widely used in traditional Chinese medicine formula, including Chaihu Shugan San, which has been clinically used for treatment of depression. However, the optimal ratio of the XF-CX herbal medicine pair and its antidepressant constituents are still unclear. Herein, the antidepressive-like effects of XF-CX herbal medicine pairs with different ratios of XF and CX (2:1, 1:1, 1:2) were evaluated using behavioral despair animal models in mice, and then its potential antidepressant constituents were recognized by spectrum-effect relationship analyses. Finally, the potential antidepressant constituents of the XF-CX herbal medicine pair were validated by molecular docking with glucocorticoid receptor and corticosterone (CORT)-induced PC12 cell injury model. The results indicated that different ratios of XF-CX pairs had antidepressive-like effects, and the XF-CX (2:1) exhibited a more significant effect. Thirty-two potential antidepressant constituents in the XF-CX herbal medicine pair were screened out from the spectrum-effect relationship combined molecular docking analyses. Among them, senkyunolide A, cyperotundone, Z-ligustilide, and levistilide A were validated to have protective effects against CORT-induced injury in PC12 cells. Our findings not only obtained the optimal ratio of XF-CX in the herbal medicine pair for the treatment of depression but also its potential antidepressant constituents, which will benefit in elucidating the mechanism of action and promoting the application of the herbal medicine pair in the clinic.

Based on the association network of "drug pair-disease", 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-1ß, F2R, PLCß1, 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.

In traditional Asian medicine, Ligusticum chuanxiong Hort also known as Conioselinum anthriscoides "Chuanxiong", is mainly used for improving blood circulation or for analgesic and anti-inflammatory purposes, but they also have a long history of use for pain disorders in the head and face, such as headache. Despite the possibility that the plant is effective for diseases such as cerebral infarction and vascular dementia (VaD), the mechanism of action is not well understood. To determine if the dried rhizomes of L. chuanxiong (Chuanxiong Rhizoma, CR) methanol extract (CRex) has activity in a VaD mice model. Through network analysis, we confirm that CR is effective in cerebrovascular diseases. In mice, we induce cognitive impairment, similar to VaD in humans, by chronically reducing the cerebral blood flow by performing bilateral common carotid artery stenosis (BCAS) and administering CRex for 6 weeks. We measure behavioral changes due to cognitive function impairment and use immunofluorescence staining to confirm if CRex can inhibit the activation of astrocytes and microglia involved in the inflammatory response in the brain. We quantify proteins involved in the mechanism, such as mitogen-activated protein kinases (MAPK), in the hippocampus and surrounding white matter, and analyze gene expression and protein interaction networks through RNA sequencing to interpret the results of the study. CRex administration rescued cognitive impairment relating to a novel object and inhibited the activation of astrocytes and microglia. Western blotting analysis revealed that CRex regulated the changes in protein expression involved in MAPK signaling such as extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (p38). The administration of CRex suppressed approximately 44% of the pathological changes in gene expression caused by BCAS. CRex extract effectively inhibited cognitive impairment caused by BCAS, and the mechanism through which this occurred is inhibited activation of astrocytes and microglia.
RESUMEN
Objective: Hepatic fibrosis has been widely considered as a conjoint consequence of almost all chronic liver diseases. Chuanxiong Rhizoma (Chuanxiong in Chinese, CX) is a traditional Chinese herbal product to prevent cerebrovascular, gynecologic and hepatic diseases. Our previous study found that CX extracts significantly reduced collagen contraction force of hepatic stellate cells (HSCs). Here, this study aimed to compare the protection of different CX extracts on bile duct ligation (BDL)-induced liver fibrosis and investigate plausible underlying mechanisms. Methods: The active compounds of CX extracts were identified by high performance liquid chromatography (HPLC). Network pharmacology was used to determine potential targets of CX against hepatic fibrosis. Bile duct hyperplasia and liver fibrosis were evaluated by serologic testing and histopathological evaluation. The expression of targets of interest was determined by quantitative real-time PCR (qPCR) and Western blot. Results: Different CX extracts were identified by tetramethylpyrazine, ferulic acid and senkyunolide A. Based on the network pharmacological analysis, 42 overlap targets were obtained via merging the candidates targets of CX and liver fibrosis. Different aqueous, alkaloid and phthalide extracts of CX (CXAE, CXAL and CXPHL) significantly inhibited diffuse severe bile duct hyperplasia and thus suppressed hepatic fibrosis by decreasing CCCTC binding factor (CTCF)-c-MYC-long non-coding RNA H19 (H19) pathway in the BDL-induced mouse model. Meanwhile, CX extracts, especially CXAL and CXPHL also suppressed CTCF-c-MYC-H19 pathway and inhibited ductular reaction in cholangiocytes stimulated with taurocholate acid (TCA), lithocholic acid (LCA) and transforming growth factor beta (TGF-ß), as illustrated by decreased bile duct proliferation markers. Conclusion: Our data supported that different CX extracts, especially CXAL and CXPHL significantly alleviated hepatic fibrosis and bile duct hyperplasia via inhibiting CTCF-c-MYC-H19 pathway, providing novel insights into the anti-fibrotic mechanism of CX.

Chuanxiong rhizoma (CX) has been utilized for centuries as a traditional herb to treat blood stasis syndromes. However, the pharmacological mechanisms are still not completely revealed. This research was aimed at exploring the molecular mechanisms of CX treatment for thrombosis. Network pharmacology was used to predict the potential anti-thrombosis mechanism after correlating the targets of active components with targets of thrombosis. Furthermore, we verified the mechanism of using CX to treat thrombosis via molecular docking and in vitro experiments. Network pharmacology results showed that a total of 18 active ingredients and 65 targets of CX treatment for thrombosis were collected, including 8 core compounds and 6 core targets. We revealed for the first time that tissue factor (TF) had a close relationship with most core targets of CX in the treatment of thrombosis. TF is a primary coagulation factor in physiological hemostasis and pathological thrombosis. Furthermore, core components of CX have strong affinity for core targets and TF according to molecular docking analysis. The in vitro experiments indicated that Ligustilide (LIG), the representative component of CX, could inhibit TF procoagulant activity, TF mRNA and protein over-expression in a dose-dependent manner in EA.hy926 cells through the PI3K/Akt/NF-κB signaling pathway. This work demonstrated that hemostasis or blood coagulation was one of the important biological processes in the treatment of thrombosis with CX, and TF also might be a central target of CX when used for treating thrombosis. The inhibition of TF might be a novel mechanism of CX in the treatment of thrombosis.

Chuanxiong Rhizoma (CX, the dried rhizome of Ligusticum wallichii Franch.), a well-known traditional Chinese medicine, is clinically used for treating cardiovascular, cerebrovascular and hepatobiliary diseases. Cholestatic liver damage is one of the chronic liver diseases with limited effective therapeutic strategies. Currently, little is known about the mechanism links between CX-induced anti-cholestatic action and intercellular communication between cholangiocytes and hepatic stellate cells (HSCs). The study aimed to evaluate the hepatoprotective activity of different CX extracts including the aqueous, alkaloid, phenolic acid and phthalide extracts of CX (CXAE, CXAL, CXPA and CXPHL) and investigate the intercellular communication-related mechanisms by which the most effective extracts work on cholestatic liver injury. The active compounds of different CX extracts were identified by UPLC-MS/MS. A cholestatic liver injury mouse model induced by bile duct ligation (BDL), and transforming growth factor-ß (TGF-ß)-treated human intrahepatic biliary epithelial cholangiocytes (HIBECs) and HSC cell line (LX-2 cells) were used for in vivo and in vitro studies. Histological and other biological techniques were also applied. The results indicated that CXAE, CXAL and CXPHL significantly reduced ductular reaction (DR) and improved liver fibrosis in the BDL mice. Meanwhile, both CXAE and CXPHL suppressed DR in injured HIBECs and reduced collagen contraction force and the expression of fibrosis biomarkers in LX-2 cells treated with TGF-ß. CXPHL suppressed the transcription and transfer of plasminogen activator inhibitor-1 (PAI-1) and fibronectin (FN) from the 'DR-like' cholangiocytes to activated HSCs. Mechanistically, the inhibition of PAI-1 and FN by CXPHL was attributed to the untight combination of the acetyltransferase KAT2A and SMAD3, followdd by the suppression of histone 3 lysine 9 acetylation (H3K9ac)-mediated transcription in cholangiocytes. In conclusion, CXPHL exerts stronger anti-cholestatic activity in vivo and in vitro than other CX extracts, and its protective effect on the intracellular communication between cholangiocytes and HSCs is achieved by reducing KAT2A/H3K9ac-mediated transcription and release of PAI-1 and FN.
RESUMEN
To optimize the extraction process of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair by network pharmacology combined with analytic hierarchy process(AHP)-entropy weight method and multi-index orthogonal test. The potential active components and targets of Chuanxiong Rhizoma-Gastrodiae Rhizoma were screened by network pharmacology and molecular docking, and the process evaluation indexes were determined with reference to the Chinese Pharmacopoeia(2020 edition). The core components of Chuanxiong Rhizoma-Gastrodiae Rhizoma were determined as gastrodin, parishin B, parishin C, parishin E, ferulic acid, and 3-butylphthalide. With the extraction volume of each indicator and yield of dry extract as comprehensive evaluation indicators, the extraction conditions were optimized by the AHP-entropy weight method and orthogonal test as the ethanol volume of 50%, the solid-liquid ratio of 1â¶8(g·mL~(-1)), extraction for three times, and 1.5 h each time. Through network pharmacology and molecular docking, the process evaluation index was determined, and the optimized process was stable and reproducible for the extraction of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair, which could provide reference for in-depth research.

Chuanxiong Rhizoma is a traditional Chinese medicine (TCM) that is used to promote blood circulation. We set out to improve Chuanxiong Rhizoma quality standards using a bioassay-based Effect-constituent Index (ECI). We performed high performance liquid chromatography (HPLC) analysis to determine the chemical constituents of 10 Chuanxiong Rhizoma samples from different locations. We then constructed a direct bioassay method to investigate each sample's antiplatelet aggregation effects. To screen for active ingredients that promote antiplatelet aggregation, we carried out Pearson correlation analyses between biopotency and compounds identified in the HPLC data. We developed an ECI of platelet aggregation inhibition using a multi-indicator synthetic evaluation method based on the integration of biopotency and active constituents. To further assess the biopotency-based Chuanxiong Rhizoma quality evaluation result accuracy, we compared the ECI with the chemical indicator' method. Eight common chemical fingerprints peaks indicated notable content variation among samples. Biological evaluation showed that all 10 samples could inhibit platelet aggregation, although they had significantly different biological potencies. Using spectrum-effect relationships, we determined that Ligustilide was the significant active constituent responsible for antiplatelet aggregation. Using correlation analysis, we found that ECI correlated with the Chuanxiong Rhizoma extract's platelet aggregation inhibitory effect. Additionally, ECI proved to be a good indicator of Chuanxiong Rhizoma quality, whereas chemical indicators failed to distinguish and predict the biopotency-based quality grade. This work indicates that ECI is a useful tool for associating sample quality with chemical markers linked to TCM clinical effects. ECI also provides a paradigm for improving the quality control of other TCMs that invigorate blood circulation.

The herb pair Epimedii Folium-Chuanxiong Rhizoma (EF-CR), derived from the classical traditional Chinese medicine 'Xian Ling Pi San', has a distinctive compatibility therapeutic profile and is clinically safe and effective. This study aimed to investigate and compare the pharmacokinetic characteristics of nine analytes in osteoarthritis (OA) rat plasma after the oral administration of EF, CR or a combination of these two herbs. We developed an ultra-performance liquid chromatography method coupled with quadrupole linear ion-trap mass spectrometry to simultaneously quantify and assess the pharmacokinetics of icariin, epimedin A, epimedin B, epimedin C, icariside I, icariside II, ferulic acid, ligustilide and senkyunolide A of the EF-CR pair in the plasma of osteoarthritic rats. The pharmacokinetic parameters showed that the absorption of multiple components was significantly enhanced and residence time was prolonged in the EF-CR group (P < 0.05) compared to the single-herb group. These parameters revealed that the combination of EF and CR exhibited synergistic effects of the nine bioactive components, suggesting the potential application of the EF-CR combination for the treatment of OA.

Alzheimer's disease (AD) is the most common cause of neurodegenerative dementia and one of the top medical concerns worldwide. Currently, the approved drugs to treat AD are effective only in treating the symptoms, but do not cure or prevent AD. Although the exact causes of AD are not understood, it is recognized that tau aggregation in neurons plays a key role. Chuanxiong Rhizoma (CR) has been widely reported as effective for brain diseases such as dementia. Thus, we explored the protections of CR in AD by a tau pathogenesis-based network pharmacology approach. According to ultra-HPLC with triple quadrupole mass spectrometry data and Lipinski's rule of five, 18 bioactive phytochemicals of CR were screened out. They were shown corresponding to 127 tau pathogenesis-related targets, among which VEGFA, IL1B, CTNNB1, JUN, ESR1, STAT3, APP, BCL2L1, PTGS2, and PPARG were identified as the core ones. We further analyzed the specific actions of CR-active phytochemicals on tau pathogenesis from the aspects of tau aggregation and tau-mediated toxicities. It was shown that neocnidilide, ferulic acid, coniferyl ferulate, levistilide A, Z-ligustilide, butylidenephthalide, and caffeic acid can be effective in reversing tau hyperphosphorylation. Neocnidilide, senkyunolide A, butylphthalide, butylidenephthalide, Z-ligustilide, and L-tryptophan may be effective in promoting lysosome-associated degradation of tau, and levistilide A, neocnidilide, ferulic acid, L-tryptophan, senkyunolide A, Z-ligustilide, and butylidenephthalide may antagonize tau-mediated impairments of intracellular transport, axon and synaptic damages, and neuron death (especially apoptosis). The present study suggests that acting on tau aggregation and tau-mediated toxicities is part of the therapeutic mechanism of CR against AD.
RESUMEN
With the internationalization of traditional Chinese medicines (TCMs) and the increasing use of herbal medicines around the world, there are concerns over their safety. In recent years, there have been some sporadic reports of pesticide residues in Chuanxiong Rhizoma (CX), although the lack of systematic and comprehensive analyses of pesticide residues and evaluations of toxicological risks in human health has increased the uncertainty of the potential effects of pesticides exposure in humans. This study aimed to clarify the status of pesticide residues and to determine the health risks of pesticide residues in CX. The findings of this study revealed that 99 batches of CX samples contained pesticide residues ranging from 0.05 to 3013.17 µg/kg. Here, 6-22 kinds of pesticides were detected in each sample. Prometryn, carbendazim, dimethomorph, chlorpyrifos, chlorantraniliprole, pyraclostrobin, and paclobutrazol were the most frequently detected pesticides, with detection rates of 68.69-100%. Insecticides and fungicides accounted for 43.23% and 37.84% of the total pesticides detected, respectively. Here, 86.87% of the pesticide content levels were lower than 50 µg/kg, and a small number of samples contained carbofuran, dimethoate, and isofenphos-methyl exceeding the maximum residue levels (MRLs). A risk assessment based on the hazard quotient/hazard index (HQ/HI) approach revealed that the short-term, long-term, and cumulative risks of pesticide residues in CX are well below the levels that may pose a health risk. Worryingly, six banned pesticides (carbofuran, phorate sulfone, phorate-sulfoxide, isofenphos-methyl, terbufos-sulfone, and terbufoxon sulfoxide) were detected. This study has improved our understanding of the potential exposure risk of pesticide multi-residues in CX. The results of the study will have a positive impact on improving the quality and safety of CX and the development of MRLs for pesticide residues.

The volatile oil of Chuanxiong Rhizoma(CX) is known as an effective fraction. In order to seek a suitable method for processing CX and its decoction pieces, this study selected 16 volatile components as indices to investigate how different processing methods such as washing/without washing, sun-drying, baking, oven-drying and far-infrared drying at different temperatures affected the quality of CX and its decoction pieces(fresh CX was partially dried, cut into pieces, and then dried) by headspace gas chromatography-mass spectrometry(GC-MS), cluster analysis, principal component analysis and comprehensive weighted scoring. The results showed that the rapid washing before processing did not deteriorate the volatile components of CX. Considering the practical condition of production area, oven-drying was believed to be more suitable than sun-drying, baking, and far-infrared drying. The CX decoction pieces with a thickness of 0.3-0.4 cm were recommended to be oven-dried at 50 â. The integrated processing(partial drying, cutting into pieces, and drying) did not cause a significant loss of volatile components. For the fresh CX, the oven-drying at 60 â is preferred. The temperature should not exceed 60 â, and drying below 60 â will prolong the processing time, which will produce an unfavorable effect on volatile components. This study has provided the scientific evidence for field processing of CX, which is conducive to realizing the normalization and standardization of CX processing in the production area and stabilizing the quality of CX and its decoction pieces.

This study aims to explore the effect of extract of Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma, and Chuanxiong Rhizoma(hereinafter referred to as GNS) on the SIRT1-autophagy pathway of endothelial cell senescence induced by hydrogen peroxide(H_2O_2). To be specific, vascular endothelial cells were classified into the blank control group(control), model group(model), model + DMSO group(DMSO), resveratrol group(RESV), and GNS low-dose(GNS-L), medium-dose(GNS-M), and high-dose(GNS-H) groups. They were treated with H_2O_2 for senescence induction except the control. After intervention of cells in each group with corresponding drugs for 24 h, cell growth status was observed under an inverted microscope, and the formation of autophagosome under the transmission electron microscope. In addition, the changes of microtubule-associated protein 1 light chain 3ß(LC3 B) were detected by immunofluorescence staining. The autophagy flux was tracked with the autophagy double-labeled adenovirus(mRFP-GFP-LC3) fusion protein. Dansylcadaverine(MDC) staining was employed to determine the autophagic vesicles, and Western blot the expression of sirtuin 1(SIRT1), ubiquitin-binding protein p62, and LC3â ¡. After H_2O_2 induction, cells demonstrated slow growth, decreased adhesion ability, raised number of SA-ß-gal-stained blue ones, a certain number of autophagosomes with bilayer membrane and secondary lysosomes in the cytoplasm, and slight rise of autophagy flux level. Compared with the model group, GNS groups showed improved morphology, moderate adhesion ability, complete and smooth membrane, decreased SA-ß-gal-stained blue cells, many autophagosomes, autophagic vesicles, and secondary lysosomes in the cytoplasm, increased autophagolysosomes, autophagy flux level, and fluorescence intensity of LC3 B and MDC, up-regulated expression of SIRT1 and LC3â ¡, and down-regulated expression of p62, suggesting the improvement of autophagy level. GNS can delay the senescence of vascular endothelial cells. After the intervention, the autophagy flux and related proteins SIRT1, LC3â ¡and p62 changed significantly, and the autophagy level increased significantly. However, EX527 weakened the effect of Chinese medicine in delaying vascular senescence. GNS may delay the senescence of vascular endothelial cells through the SIRT1 autophagy pathway.

OBJECTIVE: To explore the molecular mechanism mediating the inhibitory effect of Chuanxiong Rhizoma against brain metastasis of lung cancer using network pharmacology methods and molecular docking. METHODS: The chemical components of Chuanxiong Rhizoma and their targets were obtained through the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. The relevant targets for brain metastasis of lung cancer were screened using the GeneCards database. Clusterpro-filerR package was used to perform GO and KEGG enrichment analysis. Cytoscape and STRING database were used to construct the "active ingredient-target-disease" network and protein-protein interaction (PPI) network of Chuanxiong Rhizoma. The core components of Chuanxiong Rhizoma and their targets in the treatment of lung cancer brain metastasis were screened based on the topological parameters, and the results were verified using molecular docking and in Chuanxiong extract- treated human lung cancer PC9 cells by detecting the core target with Western blotting. RESULTS: Forty-eight active ingredients of Chuanxiong Rhizoma including (Z)-ligustilide, butylphthalide, oleic acid, and myricetone were screened, which target 49 proteins including INS, BDNF, FOS, VEGFA, PTGS2, ESR1, MAPK14, and PTGS1. These proteins participated in 57 biological functions such as nuclear receptor activity, ligand activation, and transcription factor activity, involving 40 signaling pathways such as prolactin signaling pathway, breast cancer, and etrogen signaling. The results of molecular docking showed that myricetone, butylphthalide, 4-hydroxy-3 butylphthalide, (Z)-ligustilide, and ligustalide-E, among others, had strong affinities to 7 cores targets including BDNF, FOS, PTGS2, and MAPK14. In PC9 cells, treatment with Chuanxiong Rhizoma extract resulted in significant reductions in the phosphorylation levels of PI3K, Akt and VEGF (P < 0.01). CONCLUSION: Chuanxiong Rhizoma contains multiple active ingredients against brain metastasis lung cancer, and these ingredients act on multiple targets involving multiple signal pathways and biological functions.

Cerebral ischemia is one of the most common diseases in China, and the drug pair of Chuanxiong Rhizoma and Paeoniae Radix Rubra can intervene in cerebral ischemia to reduce the inflammatory response of cerebral ischemia and apoptosis. To reveal the intervention mechanism of Chuanxiong Rhizoma-Paeoniae Radix Rubra drug pair on cerebral ischemia systematically, computer network pharmacology technology was used in this paper to predict the target and signaling pathway of the drug pair on the intervention of cerebral ischemia, and then the molecular docking technology was used to further analyze the mechanism of the intervention. The target results were then verified by the rat cerebral ischemia model. The target network results showed that the active compounds of Chuanxiong Rhizoma-Paeoniae Radix Rubra for cerebral ischemic disease contained 30 compounds, 38 targets and 9 pathways. The main compounds included phenolic acids in Chuanxiong Rhizoma and monoterpene glycosides in Paeoniae Radix Rubra. The key targets involved mitogen-activated protein kinase 1(MAPK1), steroid receptor coactivator(SRC), epidermal growth factor receptor(EGFR), mitogen-activated protein kinase 14(MAPK14), caspase-3(CASP3), caspase-7(CASP7), estrogen receptor 1(ESR1), and mitogen-activated protein kinase 8(MAPK8), etc. The target gene functions were biased towards protein kinase activity, protein autophosphorylation, peptidyl-serine phosphorylation and protein serine/threonine kinase activity, etc. The important KEGG pathways involved Ras signaling pathway, ErbB signaling pathway and VEGF signaling pathway. Molecular docking results showed that catechin, oxypaeoniflorin, albiflorin, paeoniflorin and benzoylpaeoniflorin had strong binding ability with MAPK1, SRC, EGFR, MAPK14 and CASP7. MCAO rat experimental results showed that Chuanxiong Rhizoma-Paeoniae Radix Rubra significantly improved the cerebral ischemia injury and interstitial edema, and significantly reduced the activation of caspase-7 and the phosphorylation of ERK1/2. The Chuanxiong Rhizoma-Paeoniae Radix Rubra drug pair alleviated cerebral ischemia injury through a network model of multi-phenotype intervention by promoting cell proliferation and differentiation, reducing inflammatory factor expression, protecting nerve cells from death and figh-ting against neuronal cell apoptosis, with its action signaling pathway most related to Ras signaling pathway, ErbB signaling pathway and VEGF signaling pathway. This study provides the basis for clinical intervention of Chuanxiong Rhizoma-Paeoniae Radix Rubra drug pair on cerebral ischemia, and also provides ideas for the modernization of drug pairs.

Excitatory toxicity(ET) is an important factor of neuropathic pain(NPP) induced by central sensitization(CS), and the association of pannexin-1(Panx1)-Src-N-methyl-D-aspartate receptor subunit 2 B(NMDAR-2 B) is an important new pathway for ET to initiate CS. The present study confirmed whether the central analgesic effect of Chuanxiong Rhizoma extract(CRE) was achieved through the synchronous regulation of the brain and spinal pathways of Panx1-Src-NMDAR-2 B. In this study, dynamic and simulta-neo-us microdialysis of the brain and spinal cord in vivo combined with behavioristics, high performance liquid chromatography(HPLC)-fluorescence detection, microdialysis analysis(ISCUS~(flex)), ultrasensitive multifactorial electrochemiluminescence immunoassay, ELISA, and Western blot was employed to investigate the protein expression of NMDAR-2 B, Src, and Panx1, extracellular excitatory amino acids, cytokines, energy metabolites, and substance P in spinal dorsal horn(SDH) and anterior cingulate cortex(ACC) after CRE intervention with the rat model of spared sciatic nerve injury(SNI) as the experimental tool. Compared with the sham group, the SNI group exhibited diminished mechanical withdrawal threshold(MWT)(P<0.01), increased cold spray scores(P<0.01), glutamate(Glu), D-serine(D-Ser), and glycine(Gly) in extracellular fluids of ACC, and Glu, D-Ser, interleukin-1ß(IL-1ß), and lactic acid(Lac) in extracellular fluids of SDH(P<0.05), dwindled tumor necrosis factor(TNF-α)(P<0.05), and elevated protein levels of NMDAR-2 B, Src, and Panx1 in ACC(P<0.05). Compared with the SNI model rats, high-and medium-dose CRE(CRE-H/M) could potentiate the analgesic activity as revealed by the MWT test(P<0.05) and CRE-M enabled the decrease in cold spray scores(P<0.05). CRE-H/M could inhibit the levels of Glu, D-Ser and Gly in the extracellular fluids of ACC(P<0.05), and the levels of Glu in the extracellular fluids of SDH(P<0.05) in SNI rats. CRE-M significantly increased the levels of glucose(Gluc), Lac, interferon-gamma(IFN-γ), keratinocyte chemoattractant/human growth-regulated oncogenes(KC/GRO), and IL-4 in extracellular fluids of SDH in SNI rats(P<0.05). CRE-H/M/L could also inhibit the levels of NMDAR-2 B, Src and Panx1 in ACC and SDH in SNI rats(P<0.05). The central analgesic effect of CRE is presumedly related to the inhibited release of excitatory amino acid transmitters(Glu, D-Ser and Gly) in ACC and SDH of SNI rats, decreased protein expression of NMDAR-2 B, Src and Panx1 in the two regions, and the regulation of the Panx1-Src-NMDAR-2 B pathway in the spinal cord and brain. The above findings partially clarified the scientific basis of clinical analgesic effect of Chuanxiong Rhizoma.

Fourteen classical prescriptions in the Catalog of 100 Ancient Classical Prescriptions(First Batch) promulgated in 2018 contain Chuanxiong Rhizoma, which reveals the high medicinal value and wide application of Chuanxiong Rhizoma. This paper systematically reviews the ancient herbal books and modern literature to explore the name, origin, genuine producing area, medicinal part, harvesting, and processing of Chuanxiong Rhizoma, thus facilitating the development of classical prescriptions containing Chuan-xiong Rhizoma. It is confirmed that Chuanxiong Rhizoma, formerly known as "Xiongqiong" in Chinese, was first called "Chuanxiong" in late Tang Dynasty, which has been gradually accepted as its official name due to the rise of the status of Chuanxiong Rhizoma produced in Sichuan. The main original plant of Chuanxiong Rhizoma in past dynasties has always been deemed to be Ligusticum chuan-xiong(Umbellifera), whose rhizome serves as the medicinal part. In general, it is best harvested in summer but the harvesting time can vary with different growth environments. Since the Song Dynasty, Sichuan province has been recognized as the genuine producing area of Chuanxiong Rhizoma in light of the high yield and good quality. It is suggested that Chuanxiong Rhizoma from Sichuan be used preferentially in the development of classical prescriptions. There are multiple processing methods of Chuanxiong Rhizoma recorded in ancient medical classics, and the raw(after purifying and slicing) or wine-processed or stir-fried Chuanxiong Rhizoma is still in use today. In the development of classical prescriptions containing Chuanxiong Rhizoma, Chuanxiong Rhizoma is advised to be processed in accordance with current processing standards if the specific processing method is described in the medical classics. If not, the raw Chuanxiong Rhizoma is preferred and then processed following the processing standards of Chuanxiong Rhizoma decoction pieces in Chinese Pharmacopoeia.

BACKGROUND: Chuanxiong Rhizoma (CR) is a common traditional Chinese medicine (TCM) that has been widely used in the treatment of spinal cord injury (SCI). However, the underlying molecular mechanism of CR is still largely unknown. This study was designed to explore the bioactive components and the mechanism of CR in treating SCI based on a network pharmacology approach and experimental validation. METHODS: First, the active compounds and related target genes in CR were screened from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. Subsequently, the corresponding target genes of SCI were collected by the Therapeutic Target Database (TTD) and GeneCards database. A protein-protein interaction (PPI) network was constructed using the STRING database. Furthermore, GO function and KEGG enrichment analysis of the targets were analyzed using DAVID tools. Subsequently, the AutoDock software for molecular docking was adopted to verify the above network pharmacology analysis results between the active components and key targets. Finally, an SCI rat model animal validation experiment was assessed to verify the reliability of the network pharmacology results. RESULTS: There were 7 active ingredients identified in CR and 246 SCI-related targets were collected. Then, 4 core nodes (ALB, AKT1, MAPK1, and EGFR) were discerned via construction of a PPI network of 111 common targets. The KEGG enrichment analysis results indicated that the Ras signaling pathway, estrogen signaling pathway, and vascular endothelial growth factor (VEGF) signaling pathway were enriched in the development of SCI. The results of molecular docking demonstrated that the effects of CR have a strong affinity with the 4 pivotal targets. Experimental validation in a rat model showed that CR could effectively improve the recovery of motor function and mechanical pain threshold after SCI. CONCLUSIONS: In summary, it revealed the mechanism of CR treatment for SCI involve active ingredients, targets and signaling pathways, providing a scientific basis for future investigations into the mechanism underlying CR treating for SCI.
