A total of 46 active ingredients of Coptidis Rhizoma and Pinelliae Rhizoma were screened, as well as 77 corresponding targets, 38 targets related to gastric cancer and its complications, top 8 related signaling pathways, and top 20 target molecular functions by GO analysis. Cell experiments also proved that Coptidis Rhizoma and Pinelliae Rhizoma could effectively inhibit the proliferation, invasion and migration ability of gastric cancer cells and inhibit TGF-β1-induced Wnt/β-catenin signaling pathway activation. Coptidis Rhizoma and Pinelliae Rhizoma drug pair has many active ingredients, which can regulate nervous and mental system, cell cycle, cell differentiation and metastasis, and enhance anti-inflammatory and immune functions, playing a synergistic anti-cancer role in gastric cancer and its complications and providing new ideas for the follow-up clinical treatment of gastric cancer.Wogonin is a main effective component of Scutellaria baicalensis, with a significant anti-cancer activity. Recently, extensive studies focused on anti-cancer pharmacological effects of wogonin, but there were still a few studies on its molecular mechanism. Therefore, the molecular targets of its anti-cancer activity were still unclear. In this study, network pharmacology was applied to investigate the potential targets and molecular pathway of wogonin in inhibiting the growth of colorectal cancer. It indicated that Wnt/β-catenin was a key pathway of wogonin on colorectal cancer. Then, pharmacology and molecular mechanism studies were performed according to network pharmacological results. Pharmacological results revealed that wogonin inhibited significantly the proliferation of SW480(P less then 0.001), with a concentration-dependent regularity in the range of 12.5-50 μmol·L~(-1). Additionally, wogonin could induce G_1 phase blocking of SW480 cells. Western blot was used to investigate the effect of wogonin on four characteristic proteins of Wnt/β-catenin pathway. CTNNB1(β-catenin), BIRC5(survivin) and GSK3 B were down-regulated significantly, while the expression level of BAX was up-regulated(P less then 0.05). In conclusion, wogonin could inhibit the proliferation of SW480 cells through Wnt/β-catenin pathway. The feature protein CTNNB1(β-catenin), BIRC5(survivin), GSK3 B and BAX were identified as the potential targets. This study illuminated the anti-cancer molecular mechanism and drug targets of wogonin, which provided a theoretical basis for anti-colon cancer drug discovery and clinical application.The network pharmacology was used to explore the potential active ingredients and action mechanisms of Mongolian medicine Cymbaria in the treatment of type 2 diabetes. According to the literatures collected, Cymbaria component database was established to define important active ingredients and key targets for the anti-hyperglycemic effect to predict action mechanism by active ingredient screening and target prediction techniques. Molecular docking predicted binding activity of main active components with key targets in Cymbaria, then verified the action mechanism in vitro. The Cymbaria component database contained 177 chemical components, 90 chemical structures were confirmed, including 34 chemical components with effective targets. According to the prediction results from network pharmacology, 61 biological processes were significantly affected, such as fatty acid metabolism including PPARs signaling pathway, protein kinase activity and insulin signal pathway. Moreover, the key target proteins were Akt1 and TNFα and quercetin, luteolin and catalpol were the main active ingredients of Cymbaria. Molecular docking prediction showed that luteolin, quercetin and catalpol had a strong binding activity with Akt1; luteolin had strong binding activity but quercetin and catalpol had a certain binding activity with TNFα. Furthermore, catalpol showed hypoglycemic effects in vitro, which up-regulated p-Akt(Ser473)/Akt, PPARα and PPARδ levels and reduced FABP4 expression to regulate glycose and lipid metabolism for improving insulin sensitivity. The network pharmacology predicted that the hypoglycemic effect of Cymbaria was mainly related to anti-inflammatory and lipid regulation with a multi-component, multi-target manner. It provided a scientific view of hypoglycemic effect and action mechanism of Cymbaria for further study.Sophorae Flavescentis Radix is prepared from the root of Sophora flavescens. The comprehensive knowledge of the effective components in S. flavescens makes its quality standard improvement more possible. TLC identification method for main flavonoids and alkaloids in one test was established using GF_(254) thin layer plate and the lower solution of chloroform-methanol-water-formic acid(4∶2∶1∶0.6) as developing solvent. The quantitative method of marker alkaloids was revised including the simplified sample preparation procedure and the chromatographic conditions. The determination of four alkaloids in the samples indicated that 32 batches of tested samples were qualified ones. The total oxymatrine and matrine, total oxysophocarpine and sophocarpine, as well as total amount of four tested components in the different samples were 1.08%-2.55%, 0.369%-0.860%, 1.67%-3.40%, respectively. There was a significantly positive correlation between oxymatrine and oxysophocarpine. Total oxymatrine and matrine had same correlation with total oxysophocarpine and sophocarpine. The moisture content and extractive in 32 batches of samples fulfilled the require of not more than 11.0% and not less than 20.0%, respectively. Thirteen tested pesticides were not detected in 12 batches of samples. The present study provided the evidence for the revision of quality standard of Sophora Flavescentis Radix.Paridis Rhizoma is prepared from the dried rhizoma of Paris polyphylla var. yunnanensis or P. polyphylla var. chinensis. For the improvement of the quality standard of Paridis Rhizoma described in Chinese Pharmacopoeia(2015 edition), it is proposed that the quality marker no longer contains polyphyllin Ⅵ, and instead, polyphyllin H is an alternative for the quantitative analysis. [https://www.selleckchem.com/products/Carboplatin.html Carboplatin] To determine polyphyllin Ⅰ, Ⅱ, H and Ⅶ in the Paridis Rhizoma samples collected from the different growing area in China, HPLC method was established using the same chromatographic conditions as those for simultaneous determination of polyphyllin Ⅰ, Ⅱ, Ⅵ and Ⅶ described in Chinese Pharmacopoeia(2015 edition). The methodology validation indicated that there was a good linearity among the ranges of 0.006 48-0.828, 0.006 52-0.834, 0.006 17-0.790, 0.006 31-0.808 g·L~(-1) for polyphyllin Ⅰ, Ⅱ, H and Ⅶ, respectively. The average recoveries of four components were 100.2%-101.4%, with RSD less than 3.5%. The total amount of polyphyllin Ⅰ, Ⅱ, H and Ⅶ in the analyzed samples of P.
