RESUMEN
In order to characterize and identify the chemical components in different parts of Artemisia argyi(roots, stems, leaves, and seeds), compounds with antioxidant activity were screened. In this study, ultra-performance liquid chromatography-2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt-quadrupole time-of-flight-tandem mass spectrometry(UPLC-ABTS-Q-TOF-MS) was used as an online combination technique. Poroshell 120 SB-Aq(3.0 mm×150 mm, 2.7 µm) was used as the column, and acetonitrile(A)-0.2% formic acid water(B) was adopted as the mobile phase to perform gradient elution and was scanned in positive and negative ion modes. MassLynx software was utilized, and combined with reference substances and related literature, the chemical components of different parts of A. argyi were identified and compared. The antioxidant active components were detected by using the online detection system, and the antioxidant activities of active components of different parts of A. argyi were compared and evaluated by scavenging efficiency. As a result, a total of 87 compounds were identified from extracts of different parts of A. argyi, and 38, 72, 85, and 33 components were identified from roots, stems, leaves, and seeds. 22 compounds with antioxidant activity were screened, and 14, 17, 20, and 11 compounds with antioxidant activity were identified from roots, stems, leaves, and seeds. The results show that there are certain differences in chemical components and antioxidant components of different parts of A. argyi, which provides data support for the resource utilization and further research and development of A. argyi.

Hyperlipidemia has been highlighted as one of the most prominent and global chronic conditions nowadays. Bidens bipinnata L. (BBL), a folk medicine in contemporary China, has efficacy in the treatment of hyperlipidemia (HLP) in China. Although some physiological and pathological function parameters of hyperlipidemia have been investigated, little information about the changes in small metabolites in biofluids has been reported. In the present study, global metabolic profiling with high-performance liquid chromatography-linear ion trap/Orbitrap high-resolution mass spectrometry (HPLC-LTQ/Orbitrap MS) combined with a pattern recognition method was performed to discover the underlying lipid-regulating mechanisms of BBL on hyperlipidemic rats induced by high-fat diet (HFD). The total of four metabolites, up- or down-regulated (p < 0.05 or 0.01), were identified and contributed to the progression of hyperlipidemia. These promising identified biomarkers underpin the metabolic pathway, including glyoxylate and dicarboxylate metabolism, the TCA cycle, sphingolipid metabolism and purine metabolism. They are disturbed in hyperlipidemic rats, and are identified using pathway analysis with MetPA. The altered metabolite indices could be regulated closer to normal levels after BBL intervention. The results demonstrated that urinary metabolomics is a powerful tool in the clinical diagnosis and treatment of hyperlipidemia to provide information on changes in metabolite pathways.

Bidens bipinnata L. is a folk medicinal plant in China that shows significant antihyperlipidemia effectiveness. However, studies of the underlying mechanism study are lacking. In order to explore the potential action sites and the underlying mechanism of treating hyperlipidemic, this work undertook tissue distribution and molecular docking research on the markers of B. bipinnata L., which were obtained through serum pharmacochemistry and network database retrieval. The results showed that seven compounds (gallic acid, protocatechuic acid, rutin, hyperoside, bipinnate polyacetylenicloside, luteolin and quercetin) were screened out as markers. Owing to the diversity of chemical structures, they exhibited an inconsistent trend in tissue distribution. However, all of them had high levels in the liver and no specific distribution in other tissues. More interestingly, seven proteins-HMGCR (1HWK), NR3C1 (4P6W), CYP1A2 (2HI4), RXRA (4PP3), CES1 (1MX1), HSD11B1 (2RBE) and CYP1A1 (4I8V)-showed significant binding affinity with three or more markers, suggesting that they may be the target proteins of B. bipinnata L. This study preliminarily sheds light on the tissue distribution and targets of B. bipinnata L., providing some useful information on the underlying mechanisms of the antihyperlipidemia effect.

The present research aimed to establish an associated two-dimensional fingerprint of Huanglian between characteristic chemical composition and antioxidant activity, which was applied to on-line screen the active constituents. In this study, the HPLC-ABTS-DAD-Q-TOF/MS method, which can simultaneously identify individual components and rapidly screen for antioxidant compounds, was used to screen and identify antioxidant components in Huanglian. Fourteen compositions were discovered, and eight of them displayed antioxidant activity. The antioxidant activity of different ingredients was evaluated by antioxidant efficiency. The data showed that 2, 3, 4-trihydroxy phenylpropionic acid, chlorogenic acid, ferulic acid, cularine, 3-O-feruloylquinic acid and feruloyltyramine showed stronger antioxidant activity than that of alkaloids. These experimental data can provide data support for the basic research of the antioxidant ingredients of Huanglian.

Xiexin Tang (XXT) is a traditional Chinese medicine (TCM) that has been used in herbal clinics for more than 1800 years. Many studies have shown that XXT has therapeutic effects on patients with arteriosclerosis owing to its antioxidant activity. However, there is little information about the relationship between the chemical composition of XXT and its antioxidant activity. In this study, the HPLC-ABTS-DAD-Q-TOF/MS method, which can simultaneously identify individual components and rapidly screen for antioxidant compounds, was used to screen and identify antioxidant components in XXT. The 15 compounds identified were gluco-syringic acid, adenine, gallic acid, biflorin, cularine, 6-C-arabinose-8-C-glucose-chrysin, 6-C-glucose-8-C-arabinose-chrysin, baicalin, rhein-8-O-ß-d-glucopyranoside, coptisine, epiberberine, jatrorrhizine, norwogonin, 5,7,2'-trihydroxy-6- methoxyflavone and baicalein. In addition, the data showed that the antioxidant activity of peaks 4, 6, and 11 was lower in XXT than in its constituent herbs, while the activity of peaks 1, 2, 3, 5, 7, 8, 10, 12, 13, 14 and 15 was higher in XXT. Compound 5 had the strongest antioxidant activity in XXT, while compound 1 showed the strongest antioxidant activity among its constituent herb. The differences between antioxidant activities of major components of XXT and those of its constituent herbs might be due to the interaction of crude drugs that changes the solubility of active components during the decoction process. The results show that the HPLC-ABTS-DAD-Q-TOF/MS method can successfully combine on-line mass spectrometry with activity detection system. It is a useful tool for the rapid detection and identification of antioxidants, and for quantitative analysis of individual antioxidants in complex mixtures such as plant extracts. Furthermore, this method does not require extensive extract purification and fraction collection.

The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.

Bio-active components from Carthamus tinctorius were separated on the basis of antioxidant capacities in vitro. The antioxidant capacity was investigated on the basis of the ability to scavenge DPPH radical, ABTS radical and reduce Fe3+ of different polar fractions. Furthermore, the chemical compounds were isolated from bio-active fraction, and were evaluated for the antioxidative effects. Five major components were isolated and identified from water extract as 6-hydroxykaempferol 3,6,7-tri-O-ß-D-glucoside(1), 6-hydroxykaempferol 3-O-ß-rutinoside-6-O-ß-D-glucoside (2), 6-hydroxykaempferol 3-O-ß-D-glucoside (3), hydroxysafflor yellow A (4) and anhydrosafflor yellow B (5). By evaluating and comparing the antioxidative effects of different fractions and obtained compounds, the results showed that water extract displayed significantly high antioxidative activities and 6-hydroxykaempferol glycosides and quinochalcone C-glycosides were found as main contribution for antioxidant property.

BACKGROUND: Atherosclerosis (AS) is a chronic inflammatory disease characterized by the accumulation of lipids, the formation of lesion plaques, and the narrowing of arterial lumens. Rhubarb has significant effects against AS, but there is a lack of analysis and exploration of the mechanism of action of the transitional components in serum containing rhubarb. OBJECTIVE: This work aims to combine serum pharmacochemistry, network pharmacology, and molecular docking to explore active ingredients and mechanism of rhubarb against AS. METHOD: Firstly, the components of rhubarb in blood samples were identified using HPLC-QTOF/MS. The ingredients-targets-disease interaction network of rhubarb was constructed through network pharmacology. Then, molecular docking between the ingredients and the core targets was carried out using the Autodock Vina software. RESULTS: Eleven active ingredients and five metabolites were preliminarily identified. The network pharmacology results showed that chrysophanol, resveratrol, and emodin might have potential pharmacological effects on AS. The PPI network showed that the key proteins were PTGS2, ESR1, PTGS1, and ELANE. GO analysis revealed that genes were mainly enriched in the inflammatory response and response to exogenous stimuli. Moreover, these genes were related to IL-17 signaling pathways, lipid and atherosclerosis, and other pathways. Molecular docking analyses showed that chrysophanol and emodin have strong binding affinities with the target proteins PTGS2 and PTGS1. CONCLUSION: A comprehensive strategy combining serum pharmacochemistry with network pharmacology and molecular docking was employed to investigate the active ingredients and the mechanism of rhubarb in treating AS, which provided a basis for studying the pharmacological effects and action mechanisms of rhubarb.
RESUMEN
Although uncoupling protein 4 (UCP4) is the most abundant protein reported in the brain, the biological function of UCP4 in cerebellum and pathological outcome of UCP4 deficiency in cerebellum remain obscure. To evaluate the role of Ucp4 in the cerebellar Purkinje cells (PCs), we generated the conditional knockdown of Ucp4 in PCs (Pcp2cre;Ucp4fl/fl mice) by breeding Ucp4fl/fl mice with Pcp2cre mice. Series results by Western blot, immunofluorescent staining, and triple RNAscope in situ hybridization confirmed the specific ablation of Ucp4 in PCs in Pcp2cre;Ucp4fl/fl mice, but did not affect the expression of Ucp2, the analog of Ucp4. Combined behavioral tests showed that Pcp2cre;Ucp4fl/fl mice displayed a characteristic bradykinesia in the spontaneous movements. The electromyogram recordings detection excluded the possibility of hypotonia in Pcp2cre;Ucp4fl/fl mice. And the electrical patch clamp recordings showed the altered properties of PCs in Pcp2cre;Ucp4fl/fl mice. Moreover, transmission electron microscope (TEM) results showed the increased mitochondrial circularity in PCs; ROS probe imaging showed the increased ROS generation in molecular layer; and finally, microplate reader assay showed the significant changes of mitochondrial functions, including ROS, ATP, and MMP in the isolated cerebellum tissue. The results suggested that the specific knockdown of mitochondrial protein Ucp4 could damage PCs possibly by attacking their mitochondrial function. The present study is the first to report a close relationship between UCP4 deletion with PCs impairment, and suggests the importance of UCP4 in the substantial support of mitochondrial function homeostasis in bradykinesia. UCP4 might be a therapeutic target for the cerebellar-related movement disorder.

Mitochondrial networks are defined as a continuous matrix lumen, but the morphological feature of neuronal mitochondrial networks is not clear due to the lack of suitable analysis techniques. The aim of the present study is to develop a framework to capture and analyze the neuronal mitochondrial networks by using 4-step process composed of 2D and 3D observation, primary and secondary virtual reality (VR) analysis, with the help of artificial intelligence (AI)-powered Aivia segmentation an classifiers. In order to fulfill this purpose, we first generated the PCs-Mito-GFP mice, in which green fluorescence protein (GFP) could be expressed on the outer mitochondrial membrane specifically on the cerebellar Purkinje cells (PCs), thus all mitochondria in the giant neuronal soma, complex dendritic arborization trees and long projection axons of Purkinje cells could be easily detected under a laser scanning confocal microscope. The 4-step process resolved the complicated neuronal mitochondrial networks into discrete neuronal mitochondrial meshes. Second, we measured the two parameters of the neuronal mitochondrial meshes, and the results showed that the surface area (µm2) of mitochondrial meshes was the biggest in dendritic trees (45.30 ± 53.21), the smallest in granular-like axons (3.99 ± 1.82), and moderate in soma (27.81 ± 22.22) and silk-like axons (17.50 ± 15.19). These values showed statistically different among different subcellular locations. The volume (µm3) of mitochondrial meshes was the biggest in dendritic trees (9.97 ± 12.34), the smallest in granular-like axons (0.43 ± 0.25), and moderate in soma (6.26 ± 6.46) and silk-like axons (3.52 ± 4.29). These values showed significantly different among different subcellular locations. Finally, we found both the surface area and the volume of mitochondrial meshes in dendritic trees and soma within the Purkinje cells in PCs-Mito-GFP mice after receiving the training with the simulating long-term pilot flight concentrating increased significantly. The precise reconstruction of neuronal mitochondrial networks is extremely laborious, the present 4-step workflow powered by artificial intelligence and virtual reality reconstruction could successfully address these challenges.
RESUMEN
Mitochondria play an essential role in pathophysiology of both inflammatory and neuropathic pain (NP), but the mechanisms are not yet clear. Dynamin-related protein 1 (Drp1) is broadly expressed in the central nervous system and plays a role in the induction of mitochondrial fission process. Spared nerve injury (SNI), due to the dysfunction of the neurons within the spinal dorsal horn (SDH), is the most common NP model. We explored the neuroprotective role of Drp1 within SDH in SNI. SNI mice showed pain behavior and anxiety-like behavior, which was associated with elevation of Drp1, as well as increased density of mitochondria in SDH. Ultrastructural analysis showed SNI induced damaged mitochondria into smaller perimeter and area, tending to be circular. Characteristics of vacuole in the mitochondria further showed SNI induced the increased number of vacuole, widened vac-perimeter and vac-area. Stable overexpression of Drp1 via AAV under the control of the Drp1 promoter by intraspinal injection (Drp1 OE) attenuated abnormal gait and alleviated pain hypersensitivity of SNI mice. Mitochondrial ultrastructure analysis showed that the increased density of mitochondria induced by SNI was recovered by Drp1 OE which, however, did not change mitochondrial morphology and vacuole parameters within SDH. Contrary to Drp1 OE, down-regulation of Drp1 in the SDH by AAV-Drp1 shRNA (Drp1 RNAi) did not alter painful behavior induced by SNI. Ultrastructural analysis showed the treatment by combination of SNI and Drp1 RNAi (SNI + Drp1 RNAi) amplified the damages of mitochondria with the decreased distribution density, increased perimeter and area, as well as larger circularity tending to be more circular. Vacuole data showed SNI + Drp1 RNAi increased vacuole density, perimeter and area within the SDH mitochondria. Our results illustrate that mitochondria within the SDH are sensitive to NP, and targeted mitochondrial Drp1 overexpression attenuates pain hypersensitivity. Drp1 offers a novel therapeutic target for pain treatment.

ETHNOPHARMACOLOGICAL RELEVANCE: Hyperlipidemia (HLP) is a prevalence chronic cardiovascular disease, which is treated by traditional Chinese medicine (TCM) in China. More and more attention has been paid to the application of metabolomics in the study of TCM. Bidens bipinnata L. (BBL), a folk medicine in contemporary China, has the efficacy in the treatment of hyperlipidemia (HLP) in China. However, little is known of the underlying mechanism of BBL. This research aimed to investigate ameliorative effects of BBL on hyperlipidemic rats and explore the mechanism by metabolomics method. MATERIALS AND METHODS: Hyperlipidemic rats were established by high fat diet (HFD). Biochemical assay was used to evaluate the efficacy of BBL. A metabolomics approach based on high performance liquid chromatography-linear ion trap/orbitrap high-resolution mass spectrometry (HPLC-LTQ/orbitrap MS) was performed to analyze the serum biomarkers from model group, control group and BBL group. Principle component analysis (PCA) and partial least-squares discriminate analysis (PLS-DA) were utilized to identify differences of metabolic profiles in rats among the three groups. In order to identify possible pathways that were affected by HLP, the identified endogenous metabolites were analyzed by using MetaboAnalyst. In the network pharmacology study, our research group found that PPAR signaling pathway was the most important pathway of BBL in the treatment of HLP. Then, it was found that changes in the major metabolic pathways would affect the PPAR signaling pathway through comprehensive analysis based on KEGG database. Therefore, the expression of key genes in the PPAR signaling pathway was detected by real-time quantitative fluorescence PCR (RT-qPCR). RESULTS: Six metabolites, which showed a significantly restoring trend from HLP to normal condition, were regarded as potential biomarkers of BBL treatment. The levels of phosphorylcholine, mevalonic acid and leukotriene B4 (LTB4) increased significantly (P < 0.01) in hyperlipidemic rats, while the levels of linoleic acid, arachidonic acid (AA) and lysophosphatidylcholine (18:0) (Lyso PC (18:0)) decreased significantly (P < 0.01) in comparison with control rats. Those endogenous metabolites were chiefly involved in linoleic acid metabolism, AA metabolism and terpenoid backbone biosynthesis. According to the results of RT-qPCR analysis, the mRNA expressions of PPAR α, PPAR ß and PPARγ in model group were difference compared with control group. And the expression difference could be regulated closer to normal level after BBL intervention. CONCLUSIONS: The results of biochemical assay, serum metabolic pattern and RT-qPCR analysis showed that BBL could exert a significant improvement on lipid levels, liver function, renal function, as well as the mRNA expression level of PPAR signaling pathway.

Yudanshen, the genuine medicinal materials of Danshen (Salvia miltiorrhiza), is a well-known traditional Chinese medicine (TCM) used to treat cardiovascular and cerebrovascular diseases. Although its pharmacological and antioxidative activities have been well-documented, there is little research on the hydroxyl radical (OH) scavenging capacity of Yudanshen. In this study, we established multiple on-line high-performance liquid chromatography- chemiluminescence detector-diode-quadrupole-time of flight mass spectrometry (HPLC-CL-DAD-Q-TOF/MS) methods to rapidly screen and identify the OH scavengers in Yudanshen simultaneously. The chromatographic and potency fingerprints revealed seventeen peaks that showed the inhibition of OH. Fourteen of them were identified as danshensu, protocatechuic aldehyde, caffeic acid, ferulic acid, salvianolic acid F, salvianolic acid H/L, salvianolic acid G, salvianolic acid D, salvianolic acid E, rosmarinic acid, salvianolic acid B, isosalvianolic acid B, salvianolic acid A, and salvianolic acid C. This study explores the OH scavenging activities of Yudanshen, and provides novel and powerful multiple on-line methods in the field of TCM for rapid screening and identification of OH scavengers.

Herb pair Danggui-Honghua has been frequently used for treatment of blood stasis syndrome (BSS) in China, one of the most common clinical pathological syndromes in traditional Chinese medicine (TCM). However, its therapeutic mechanism has not been clearly elucidated. In the present study, a feasible system pharmacology model based on chemical, pharmacokinetic and pharmacological data was developed via network construction approach to clarify the mechanisms of this herb pair. Thirty-one active ingredients of Danggui-Honghua possessing favorable pharmacokinetic profiles and biological activities were selected, interacting with 42 BSS-related targets to provide potential synergistic therapeutic actions. Systematic analysis of the constructed networks revealed that these targets such as HMOX1, NOS2, NOS3, HIF1A and PTGS2 were mainly involved in TNF signaling pathway, HIF-1 signaling pathway, estrogen signaling pathway and neurotrophin signaling pathway. The contribution index of every active ingredient also indicated six compounds, including hydroxysafflor yellow A, safflor yellow A, safflor yellow B, Z-ligustilide, ferulic acid, and Z-butylidenephthalide, as the principal components of this herb pair. These results successfully explained the polypharmcological mechanisms underlying the efficiency of Danggui-Honghua for BSS treatment, and also probed into the potential novel therapeutic strategies for BSS in TCM.
