ABSTRACT

This study aims to establish a method for analyzing the chemical constituents in Cistanches Herba by high performance liquid chromatography(HPLC) and quadrupole-time-of-flight tandem mass spectrometry(HPLC-Q-TOF-MS/MS), and to reveal the pharmacological mechanism based on network pharmacology for mining the quality markers(Q-markers) of Cistanches Herba. The chemical constituents of Cistanche deserticola and C. tubulosa were analyzed via HPLC-Q-TOF-MS/MS. The potential targets and pathways of Cistanches Herba were predicted via SwissTargetPrediction and DAVID. The compound-target-pathway-pharmacological action-efficacy network was constructed via Cytoscape. A total of 47 chemical constituents were identified, involving 95 targets and 56 signaling pathways. We preliminarily elucidated the pharmacological mechanisms of echinacoside, acteoside, isoacteoside, cistanoside F, 2'-acetylacteoside, cistanoside A, campneoside Ⅱ, salidroside, tubuloside B, 6-deoxycatalpol, 8-epi-loganic acid, ajugol, bartsioside, geniposidic acid, and pinoresinol 4-O-β-D-glucopyranoside, and predicted them to be the Q-markers of Cistanches Herba. This study identified the chemical constituents of Cistanches Herba, explained the pharmacological mechanism of the traditional efficacy of Cistanches Herba based on network pharmacology, and introduced the core concept of Q-markers to improve the quality evaluation of Cistanches Herba.

ABSTRACT

Lonicerae Japonicae Flos, as common Chinese medicine, has been used for thousands of years in the treatment of inflammation and infectious diseases with definite efficacies. The complex composition of Lonicerae Japonicae Flos results in its extensive pharmacological effects, so the assessment of its quality by only a few index components is not comprehensive. Guided by the quality marker(Q-marker), the present study comprehensively analyzed and predicted the quality connotation of Lonicerae Japonicae Flos based on the chemical composition and component transfer, the phylogenetic relationship, chemical composition effectiveness, measurability, and specificity. Chlorogenic acid, isochlorogenic acids A, B, and C, luteoloside, rutin, sweroside, and secoxyloganin were predicted as candidate Q-markers of Lonicerae Japonicae Flos.

ABSTRACT

Esophageal squamous cell carcinoma (ESCC) is a malignant tumor caused by both environmental and genetic factors. Epidemiology studies have identified smoking as a major environmental risk factor. In recent years, the advancement of genomics research has led to the recognition of the influence of genetic variation in ESCC. We reviewed the research progress in smoking, genetic polymorphism and their interaction on susceptibility to ESCC. Reducing exposure time to tobacco was found to be the most effective way to reduce the risk. At the genetic level, mutations in DNA repair genes, regulation genes of carcinogen-metabolizing enzymes, cell cycle regulation genes, folate metabolism related genes, and alcohol metabolism related genes were found to significantly increase the risk of ESCC. However, studies on the interaction between smoking and genetic polymorphisms in ESCC risk are still limited, more studies are needed for better screening of the high-risk populations and the prevention.

ABSTRACT

We explored the pharmacodynamic material basis and network regulatory mechanism of Fufang Yuxingcao Mixture (FYM) for the treatment of fever and inflammation. Targets of the 25 compounds in FYM were predicted according to the reverse pharmacophore method and TCMSP, UniProt database. Gene ontology (GO) function enrichment and pathway analysis of the targets was analyzed by Omicsbean software and the Kyoto Gene and Genome Encyclopedia (KEGG) database. A "compound-target-pathway-pharmacological action-effect" network was established with Cytoscape 3.6.1 software. The lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was used to verify the anti-inflammatory effects of FYM and its 10 important components. The network pharmacology experiment showed that 25 compounds affected 97 pathways through 211 targets, of which 15 key targets [including RAC-alpha serine/threonine-protein kinase (AKT1), insulin (INS), vascular endothelial growth factor A (VEGFA), interleukin-6 (IL-6), cellular tumor antigen p53 (TP53), tumor necrosis factor (TNF), transcription factor AP-1 (JUN), caspase-3 (CASP3), matrix metalloproteinase-9 (MMP9), interleukin-8 (IL-8), prostaglandin G/H synthase 2 (PTGS2), proto-oncogene c-Fos (FOS), tyrosine-protein kinase SRC (SRC), c-Jun N-terminal kinase 1 (MAPK8), estrogen receptor 1 (ESR1)] and 46 pathways (including NF-kappa B signaling pathway, Toll-like receptor signaling pathway, MAPK signaling pathway, IL-17 signaling pathway, arachidonic acid metabolism, cAMP signaling pathway, T cell receptor signaling pathway, calcium signaling pathway, inflammatory mediator regulation of TRP channels, chemokine signaling pathway, Th1 and Th2 cell differentiation, natural killer cell mediated cytotoxicity, etc.) were related to anti-inflammatory, antipyretic, immune regulation, and analgesia. In vitro cell experiments showed that FYM and the 10 components (including isoquercitrin, luteoloside, baicalein, wogonin, wogonoside, phillyrin, forsythoside A, chlorogenic acid, isochlorogenic acid A, and sweroside) could significantly reduce the expression of nitric oxide (NO), TNF-α and IL-6 in cell supernatants, indicating that the above 10 components may be the key pharmacodynamic material basis of FYM.

ABSTRACT

The study of secondary development of major Chinese materia medica varieties is the important content of Chinese materia medica (CMM) innovation research, and it is also the important approach of inheriting and developing traditional Chinese medine (TCM) theory and breaking the bottleneck restricting of the development of TCM theory and CMM industry. In this paper, the secondary development of Shufeng Jiedu Capsule (SJC) was systematically studied. The chemical components of SJC were elucidated by the identification and characterization of herbs, SJC and components ingested into the blood. The main effective components were further screened and cleared by integrating UPLC-Q/TOF-MS, NF-κB double luciferase reporter gene system, binding experiments of G protein coupled receptors, network pharmacology analysis, and spectrum-efficiency screening method. Based on the traditional efficacy, the mechanism of SJC was explained in terms of anti-inflammatory immunity, antipyretic effect, pharmacokinetics and tissue distribution of the main components based on the methods of animal model and genomics. The formula features, compatibility regularity were clarified and the action properties, comparative advantages and core clinical value were found and refined by the research of decomposed recipes and the comparison with the similar CMM recipes and chemical drugs. The quality control systems of SJC and related herbs were established by content determination of multi-target ingredients and multi-batch samples, and the establishment of the characteristic mode of HPLC fingerprint. The original quality standards were promoted comprehensively to ensure the uniformity, stability and controllability of product quality. This study not only provided important theoretical and experimental basis for clinical application and guidance of clinical practice, but also provided research ideas and modes for the secondary development of other major CMM varieties.

ABSTRACT

Haima Bushen Pills (HBP) is a kind of major Chinese materia medica varieties, which has been proven to be effective. However, due to its weak research foundation and simple quality control method, the quality of HBP cannot be evaluated scientifically and controlled effectively. In this paper, the chemical components of HBP and components ingested into the blood were identified and characterized based on the concept and determination principle of quality marker (Q-marker). Then, through the animal models, proteomics, metabolomics, network pharmacology, receptor binding and enzyme detection and other methods, its effectiveness was evaluated, the mechanism was explained, the effective components were determined, and the Q-marker was extracted. This paper provides theoretical and experimental evidence for giving full play to the clinical value and establishing a scientific quality evaluation system of HBP.

ABSTRACT

The quality definition of traditional Chinese medicine (TCM) is a hot area in modern research of TCM. In recent years, the characteristics of one herb with multiple effects have been widely accepted and studied. The typical opposite-effect of herbs is considered as a special part of one herb with multiple effects, and was summarized in this paper. Sanqi was used as an example of opposite-effect herbs for developing the strategies and approaches on the Q-markers. The traditional opposite-effect should be studied by modern pharmacological research methods. The correlation of the chemical components with the opposite effects should be established in order to verify the material basis and evaluate the mechanism including targets and pathways. The unique characteristics of chemical components should be analyzed and defined. Finally, the Q-markers of the opposite effect herb will be confirmed. This paper provides a useful reference for the precise quality control of herbal opposite-effects.

ABSTRACT

The quality of traditional Chinese medicine (TCM) is the lifeline for TCM industry. The development of artificial intelligence (AI) has provided new means for the quality management of Chinese medicinal materials (CMM). In this paper, we take the quality marker (Q-marker) as a breakthrough point, focused on the research strategy from chemical markers to Q-markers, picked up the characteristics of the Q-markers from the near infrared spectrum (NIRS), and explored the feasibility of establishing the NIRS assay based on Q-marker. After integrated the biological activity detection and artificial neural network algorithm, we try to establish the relationship between the spectral properties of NIRS and specific efficacy of the CMM. Finally, the bottlenecks will be solved that related to the transmission and traceability of quality attributes in the process of TCM production, quantity change, overall quality management and so on. This system is going to improve TCM quantity scientific and intelligent supervision, and promote the upgrading of traditional TCM industry.

ABSTRACT

BACKGROUND: Morinda officinalis oligosaccharide is the main active ingredient of morinda officinalis extract,which can promote the angiogenesis of ischemic tissue, but the mechanism is unknown. At present, there are two ways for endothelial repair:vascular endothelial cell division or differentiation from vascular endothelial progenitor cells in the peripheral blood. Here, we attempted to explain the pro-angiogenesis mechanism of morinda officinalis oligosaccharide by exploring whether there is a correlation between morinda officinalis oligosaccharide and the biological function of vascular endothelial progenitor cells, thereby providing experimental reference for new drug development. OBJECTIVE: To observe the effect of morindae officinalis oligosaccharide on the proliferation, differentiation and paracrine of vascular endothelial progenitor cells. METHODS: Vascular endothelial progenitor cells were isolated from healthy human peripheral blood, and divided into two groups: control group (without morindae officinalis oligosaccharide) and experimental group (with 0.15 g/L morindae officinalis oligosaccharide), followed by 48 hours of in vitro culture.The proliferation of vascular endothelial progenitor cells was tested by fluorescent staining;the ratio of vascular endothelial progenitor cells expressing CD31 was detected by flow cytometry; and the levels of vascular endothelial growth factor, stromal cell-derived factor 1 and interleukin 8 were analyzed by enzyme-linked immunosorbent method. RESULTS AND CONCLUSION: The percentage of vascular endothelial cells expressing CD34, CD133 or VEGFR- 2 was (84.72±4.34)%. After 48 hours of culture by 0.15 g/L morindae officinalis oligosaccharide, the proliferation rate and the positive expression of CD31 in the experimental group were significantly higher than those in the control group (P < 0.05). The levels of vascular endothelial growth factor, stromal cell-derived factor 1 and interleukin 8 in the experimental group were also higher than those in the control group (P < 0.05). To conclude, morindae officinalis oligosaccharide can promote the proliferation and differentiation of vascular endothelial progenitor cells, and meanwhile, it can stimulate the release of vascular endothelial growth factor, stromal cell-derived factor 1 and interleukin 8 from vascular endothelial progenitor cells through the paracrine pathway. Consequently, it is a potential drug for myocardial ischemic diseases.

ABSTRACT

Q-marker of Chinese materia medica (CMM) is a latest proposed core concept of CMM quality evaluation and quality control. A wide range of relevant researches on the Q-marker have been carried out by science and technology workers since the concept was put forward. However, to date, most studies are still limited to Q-marker studies of single herbs and pieces and cannot fully reflect all the elements of the concept of Q-marker. In this paper, the scientific connotation of five elements and the principles, ideas and approaches for the discovery and determination of CMM Q-marker were systemically discussed from the perspectives of quality transmissibility and traceability, ingredient specificity, component validity, component measurability, and formula compatibility environment. Moreover, research approaches of Q-marker of CMM formula based on “five principles” were proposed. The examples of representative researches provide a systematic research idea and reference for the research and discovery of CMM Q-marker.
