The chemical components of Spatholobi Caulis tannin (SCT) have a modest therapeutic effect in patients with cervical cancer. However, the active components and the mechanism of action of SCT in HeLa cervical cancer cells need to be further studied. In this paper, 3D microfluidic chip technology was applied to simulate the effects of tannins in the human body, and the appropriate dose and time of administration were calculated. The cell cycle and apoptosis experiments demonstrated that SCT inhibits proliferation and stimulated apoptosis in HeLa cells. The differentially expressed genes were screened using The Cancer Genome Atlas (TCGA) and the GEO databases to identify common differentially expressed genes. A bioinformatic analysis of relevant genes, analysis using the molecular docking technique, and survival analysis were used to predict the target genes of SCT. Circular RNAs (circRNAs) associated with the SCT target genes and the regulatory effects of SCT on these circRNAs were determined. These studies showed that SCT mediates related circRNAs in HeLa cells to inhibit proliferation and promote apoptosis in HeLa cells. Thus, SCT may be an effective strategy for treating cervical cancer. Keywords: cervical cancer, 3D microfluidic chip, bioinformatic integration, molecular docking, circRNA

Isolation and screening of different compounds from plant extracts are always the key for natural drug research, and the absorbed prototype components have been considered as potential active ingredients. UHPLC combined with quadrupole time-of-flight mass spectrometry (Q-TOF-LC/MS) has been widely used in the research of natural drugs; however, we still need a more effective tool to compare and treat from a raw data. In this study, we provided a fast analytical method to measure the absorbed prototype components and their metabolites both qualitatively and quantitatively based on molecular networking (MN). For example, in Ardisia japonica (Thunb.) Blume, a total of eight absorbed prototype components in rat plasma were identified. Furthermore, pharmacokinetic study was also successfully performed on the eight absorbed prototype components in rat plasma. Our findings have provided important information on the investigation of A. japonica in vivo. More importantly, the MS network analysis pattern serves as an integral solution for qualitative and quantitative determination of phytochemical compounds in natural drugs.

Cervical cancer is considered the fourth most common malignant disease in women. Recently, tannin from Spatholobi Caulis (TTS) has been shown to have potent anticancer and antiproliferative characteristics in a few preliminary studies. This experiment used 3D microfluidic, flow cytometry, and gene chip technology to study the efficacy and mechanism of action of TTS, as well as molecular docking technology to study the effect of drugs on related proteins. The cell survival rates of the five groups measured by the 3D microfluidic chip were 94%, 85%, 64%, 55%, and 42%, respectively. With the increase in drug concentration, the cell survival rate gradually decreased. Apoptosis rates detected in the five groups were 2.12%, 15.87%, 33.40%, 41.13%, and 55.10%, respectively. These data suggest that TTS can promote cell apoptosis. The percentages of cells in the G0/G1 phase were 43.39%, 55.07%, 59.57%, 64.56%, and 67.39% in the five groups, respectively. TTS was demonstrated to inhibit the conversion of cells from G0/G1 to S phase and G2/M phase and inhibit gene and protein synthesis to block cell proliferation. TTS can effectively modulate pathogenic proteins. The results confirmed the efficacy of TTS against HeLa cells and that TTS can be used as an adjunct in cervical cancer prevention and treatment.

As one of the major active components of Qizhiweitong (QZWT) prescription, corydalis alkaloid (CA) has been reported to have noticeable effect of anti-inflammation in pharmacological studies. However, the anti-inflammatory function and potential mechanism of CA in anti-inflammation remain to be clarified. Hence, the aim of this study was to investigate the anti-inflammation efficacy and potential mechanism of CA in anti-inflammation by metabonomic approach coupled with related gene analyzes in vivo and in vitro. Mice acute inflammation was induced by subcutaneous injection of formalin in hind paws, and evaluated the anti-inflammatory effect of CA via detecting the index of paw edema. The results indicated that CA has an anti-inflammatory effect on mice through alleviating the paw edema significantly. Moreover, metabolic profiling was performed by high performance liquid chromatography quadrupole-time-of-flight mass spectrometer (HPLC-QTOF-MS) combined with multivariate data analysis, such as principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). Thirteen metabolic targets (including lysophosphatidylcholine (LysoPC), choline, arachidonic acid, phosphodimethylethanolamine) and related pathways of the cholinergic anti-inflammatory and arachidonic acid (AA) metabolism were identified, Meanwhile, the relevant target genes, like iNOS, NF-κB, TNF-α, were detected and verified in vitro. The results indicated that CA has a good pharmacological effect of anti-inflammation through regulating multiple disordered targets and metabolic networks, which provides a theoretical basis for further research on CA. Furthermore, there is a great potential for the development of CA to be a new anti-inflammatory drug with high effective activities, little side effects and weak drug resistance.

Background: Gastric ulcer is a common chronic disease in human digestive system, which is difficult to cure, easy to relapse, and endangers human health seriously. Compared with western medicine, traditional Chinese medicine has a unique advantage in improving the general situation, stablizing medical condition, and with little side effects. Glycyrrhiza known as “king of all the medicine”, has a range of pharmacological activities and is commonly used in a variety of proprietary Chinese medicines and formulations. Objective: On the basis of explicit antiulcer effect of Glycyrrhiza triterpenes, the molecular mechanisms of its therapeutic effect on acetic acid induced gastric ulcer in rats were explored. Materials and Methods: Acetic acid induced gastric ulcer model in rats was established to evaluate the curing effect of G. triterpenes and all of the rats were randomised into six groups: Control group, model group, omeprazole group (0.8 mg/mL), triterpenes high dose group (378.0 mg/mL), triterpenes middle dose group (126.0 mg/mL), and triterpenes low dose group (42.0 mg/mL). All rats in groups were orally administered the active group solution 1.5 mL once daily (model and control groups with saline) for 7 days. HPLC-TOF-MS analysis method was performed to obtain the plasma metabolites spectrums of control group, model group, triterpenes high, middle and low dose groups. Results: A total of 11 differential endogenous metabolites related to the therapeutic effect of G. triterpenes were identified, including tryptophan, phingosine-1-phosphate, pantothenic acid, and so on, among which tryptophan and phingosine-1-phosphate are related with the calcium signaling pathway and arachidonic acid (AA) metabolism. At the same time, in order to verify the above results, quantitative real time polymerase chain reaction were performed to evaluate the expression of H+-K+-ATPase alpha mRNA and phospholipase a 2 mRNA in relational signaling pathways. Combined with statistical analysis of plasma metabolic spectrum and gene expression in tissue, it is suggested that G. triterpenes has antiulcer effect on gastric ulcer in rats. Conclusion: G. triterpenes has a certain regulating effect on the metabolism of tryptophan, AA, sphingosine, and other endogenous metabolites, and we speculated that the antiulcer potential of G. triterpenes can be primarily attributed to its inhibiting gastric acid secretion, reducing the release of inflammatory mediators, and protecting gastric mucosa effects to prevent the further development of gastric ulcer. SUMMARY G. triterpenes can obviously relieve the symptoms of gastric ulcer, especially the low dose group.G. triterpenes can effectively regulate the amount of small molecule metablism in gastric ulcer rats in vivo, including tryptophan, phingosine-1-phosphate, etc.G. triterpenes resisting gastric ulcer is probably by regulating arachidonic acid metabolism, sphingosine metabolism, etc.Down-regulation of H+-K+-ATPase alpha subunit mRNA and up-regulation of PLA2 mRNA in gastric tissue of dose group validated the possible mechanisms of G. triterpenes for the treatment of gastric ulcer Abbreviations used: HP: Helicobacter pylori, ECL: enterochromaffinlike, TCM: Traditional Chinese medicine; HPLC: High Performance Liquid Chromatography, HPLC/MS: High Performance Liquid chromatography Mass Spectrometry, HPLC-TOF-MS: High Performance Liquid Chromatography and Tof Mass Spectrometry, SD: Sprague Dawley, PCDL: Personal Compound Database and Library, MPP: Mass Profiler Professiona; PCA: principal component analysis, RT-PCR: real time polymerase chain reaction, PGE 2: Prostaglandin E2, COX1: cyclooxygenase 1 S1P: Sphingosine-1-phosphate, AA: Arachidonic acid, 5-HT: 5- hydroxytryptamine.

We demonstrated that metabolomics technology combined with gene technology is a useful tool to search different metabolites and to dissect the potential mechanisms of traditional Chinese medicine (TCM) in treating gastric ulcer.

Non-small cell lung cancer (NSCLC) is regarded as one of the major intractable diseases, which was cured mainly by chemotherapeutics in the clinical treatment at present. But it is still a vital mission for the current medical and researchers that hunting a natural medicine which have little side effects and high-efficiency against the NSCLC on account of the shortcomings on current drugs. Nepeta cataria L. plays an important role in anti-cancer treatment according to the reports which was recorded in the Chinese Pharmacopoeia of version 2015 and belongs to one of the Traditional Chinese medicine (TCM). Microfluidic chip technology is widely used in scientific research field due to its high-throughput, high sensitivity and low cost with the continuous progress of science and technology. In this study, we investigate the effect of total flavonoid extracted from Nepeta cataria L. (TFS) through human lung cancer cell line A549 based on the microfluidic device and Flow Cytometry. So we detected the mRNA expression of MicroRNA-126 (miR-126), VEGF, PI3K, PTEN and proteins expression respectively to explore the partial PI3K-AKT pathway molecular mechanisms through Quantitative Real-time PCR (qRT-PCR) and Western Blot. The results showed that TFS can disturb the expression of miR-126 and regulate the PI3K-AKT signaling pathway to meet the effect of anti-cancer. Taking all these results into consideration we can draw a conclusion that TFS may be used as a novel therapeutic agent for NSCLC in the near future.

Patrinia villosa (Thunb.) Juss. (PVJ) is described as pungent, bitter and slightly cold in Chinese medicine, and is associated with the large intestine, stomach and liver meridians.

Hydrocaffeate and scutellarein are the phase I metabolites of caffeic acid and scutellarin, respectively. Sulfated apigenin, sulfated luteolin, sulfated kaempferol and methylated kaempferol are the II phase metabolites of apigenin, luteolin, kaempferol, respectively. The experiment provides a reference for the research and development of antitumor drug candidates, and provides a basis for revealing the bioactive components of PVJ and the antitumor mechanism.

Cirsium setosum (Willd.) MB. has been reported to exert significant anti-hemorrhagic, anti-inflammation, antimicrobial, sedative and detoxicating efficacy. It has been widely used to treat gastrointestinal bleeding, uterine bleeding, infectious hepatitis and cardiovascular disease in China. Recent studies have shown that flavonoids are the main active components in C. setosum. Nevertheless, to the best of our knowledge, there is no report concerning the simultaneous determinations and pharmacokinetics of constituents in C. setosum flavonoids in rat plasma. In this study, a rapid, sensitive and selective triple quadrupole liquid chromatography-mass spectrometry method was developed to determine eight analytes from the flavonoids of C. setosum in rat plasma. In addition, the pharmacokinetic study of the eight analytes in rats after oral administration of C. setosum flavonoids was successfully completed through this method. According to the pharmacokinetic parameters of the eight analytes, rutin, naringin, quercetin, acacetin, wogonin were the long-acting components of the C. setosum flavonoids, with long elimination time and high bioavailability. Of note, the method developed in this study fills a blank in pharmacokinetic studies of C. setosum flavonoids. Our findings provide valuable views on the understanding of the absorption mechanism of C. setosum flavonoids and their clinical efficacy.

Inflammation is an important immune response; however, excessive inflammation causes severe tissue damages and secondary inflammatory injuries. The long-term and ongoing uses of routinely used drugs such as non-steroidal anti-inflammatory drugs (NSAIDS) are associated with serious adverse reactions, and not all patients have a well response to them. Consequently, therapeutic products with more safer and less adverse reaction are constantly being sought. Radix Bupleuri, a well-known traditional Chinese medicine (TCM), has been reported to have anti-inflammatory effects. However, saikosaponins (SS) as the main pharmacodynamic active ingredient, their pharmacological effects and action mechanism in anti-inflammation have not been reported frequently. This study aimed to explore the anti-inflammatory activity of SS and clarify the potential mechanism in acute inflammatory mice induced by subcutaneous injection of formalin in hind paws. Paw edema was detected as an index to evaluate the anti-inflammatory efficacy of SS. Then, a metabolomic method was used to investigate the changed metabolites and potential mechanism of SS. Metabolite profiling was performed by high-performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). The detection and identification of the changed metabolites were systematically analyzed by multivariate data and pathway analysis. As a result, 12 different potential biomarkers associated with SS in anti-inflammation were identified, including nicotinate, niacinamide, arachidonic acid (AA), and 20-carboxy-leukotriene B4, which are associated with nicotinate and nicotinamide metabolism and arachidonic acid metabolism. The expression levels of biomarkers were effectively modulated towards the normal range by SS. It indicated that SS show their effective anti-inflammatory effects through regulating nicotinate and nicotinamide metabolism and arachidonic acid metabolism.

Total flavonoids (TF), derived from the seeds of Oroxylum indicum (L.) Vent., possess many pharmacological functions. In the present study, H22-bearing mice and SMMC-7721 models were employed to evaluate the antitumor activity of TF and to and investigate its possible mechanisms both in vitro and in vivo. Cell viability was evaluated by MTT assay; cell apoptosis rate was analyzed via Annexin V-FITC/PI double staining by flow cytometer. Meanwhile, the expressions of apoptosis-related mRNA and proteins were evaluated by RT-PCR and Western blot analysis. The results revealed that TF could significantly inhibit the tumor growth, and the possible mechanism was related to the effect of inducing tumor cells apoptosis through PI3K/Akt/PTEN signaling pathway. This study has provided a theoretical basis for the further development and application of TF as antitumor drugs.

Ethnopharmacological relevance Metabolomics is the comprehensive assessment of endogenous metabolites of a biological system in a holistic context, and its property consists with the global view of Traditional Chinese Medicine (TCM). Shuihonghuazi Formula (SHHZF) has been used for liver cancer early treatment in clinical for more than thirty years, but its mechanism remains unclear completely. This paper was designed to explore the therapeutic effects of SHHZF on liver cancer and its metabolomic characters. Materials and methods All the rats were given diethylnitrosamine (DEN) at the dosage of 70 mg/kg for 14 weeks. From the 7th weeks, SHHZF was given to the rats which lasted for 10 weeks. Therapeutic effects of SHHZF was compared with that of cyclophosphamide (CTX). High performance liquid-chromatography/electrospray-ionization time of flight mass spectrometer (HPLC/ESI-TOF-MS) combined with pattern recognition approaches including principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA), was integrated to approximate the comprehensive metabolic signature and discover differentiating metabolites by Agilent MPP 12.1. The changes in metabolic profiling in plasma were restored to their baseline values after SHHZF treatment according to the PLS-DA score plots. Results The results indicated that 23 ions as “differentiating metabolites”. The alterations in those metabolites were associated with perturbations in fatty acid and bile acid metabolism, in response to liver cancer through immune and nervous system. And SHHZF could increase the uptake and utilization of linoleic acid and oleic acid, increase arachidonic acid-like substance content and enhance organism immunity of liver cancer rats. And it also could increase the translation from phosphatidylethanolamine (PE) to phosphatidylcholine (PC), linoleic acid metabolism and inhibits abnormal metabolism of bile acid. Conclusions The mechanism of therapeutic effects of SHHZF on liver cancer by adjusting the activities of PE N-methyl transferase (PEMT), Lysophospholipase D, methylenetetrahydrofolate reductase (MTHFR) and lysophospholipase was elucidated by the method of metabonomics for the first time.

Glycyrrhiza, commonly known as licorice, is a herbal medicine that has been used for thousands of years. Licorice contains multiple flavonoids, which possess a variety of biological activities. On the basis of the anti-inflammatory effects of licorice flavonoids, the potential mechanism of action was investigated via a plasma metabolomics approach. A total of 9 differential endogenous metabolites associated with the therapeutic effect of licorice flavonoids were identified, including linoleic acid, sphingosine, tryptophanamide, corticosterone and leukotriene B4. Besides classical arachidonic acid metabolism, metabolism of sphingolipids, tryptophan and fatty acids, phospholipids synthesis, and other pathways were also involved. The multi-pathway integrated adjustment mechanism of licorice flavonoid action may reduce side effects in patients, along with any anti-inflammatory functions, which provides a foundation for identifying and developing novel, high-potential natural drugs with fewer side effects for clinical application.
