["Component-target-efficacy" network analysis and experimental verification of Qingkailing Oral Preparation].

This study aims to explore the mechanism of Qingkailing(QKL) Oral Preparation's heat-clearing, detoxifying, mind-tranquilizing effects based on "component-target-efficacy" network. To be specific, the potential targets of the 23 major components in QKL Oral Preparation were predicted by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The target genes were obtained based on UniProt.

[Identification of Q-markers for Cistanches Herba based on HPLC-Q-TOF-MS/MS and network pharmacology].

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.

Therapeutic Mechanistic Studies of ShuFengJieDu Capsule in an Acute Lung Injury Animal Model Using Quantitative Proteomics Technology.

ShuFengJieDu capsule (SFJDC), a traditional Chinese medicine (TCM) that contains eight medicinal herbs, has been extensively utilized for the treatment of acute lung injury (ALI) and respiratory infections for more than 30 years in China. SFJDC has also been listed in the official guidelines of the China Food and Drug Administration (CFDA) due to its stable clinical manifestations. However, the underlying mechanism of SFJDC during ALI repair remains unclear.

[Identification of chemical constituents of Yuanhu Zhitong prescription by HPLC-QTOF/MS].

This study was designed to clarify the chemical constituents in Yuanhu Zhitong prescription (YHZT), a rapid high performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (HPLC-QTOF/MS) method was established. Based on the high resolution MS spectra data, fragment ion information, reference standards data and literature reports, 51 peaks including 28 alkaloid compounds and 23 coumarin compounds were identified. The chemical constituents in YHZT were rapidly, accurately, systematically analyzed.

[Chemical constituents and mechanism of Corydalis Rhizoma based on HPLC-QTOF/MS and G protein-coupled receptor analysis].

The chemical constituents of Corydalis Rhizoma were identified in the 60% ethanol extract using high performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (HPLC-QTOF/MS). The stimulation and inhibition effects of Corydalis Rhizoma and its representative compounds (protopine, palmatine, tetrahydropalmatine) on G protein-coupled receptor (GPCR), including 5-hydroxytryptamine 1A receptor(5-HT(1A)), μ opioid receptor (OPRM1), β(2) adrenergic receptor (ADRB2), dopamine receptor (D(2)), acetylcholine receptor (M(2)) and thromboxane-prostaglandin receptor (TP) were explored using the fluorescence assay of intracellular calcium ion. As a result, 31 compounds were obtained and 28 alkaloid compounds were identified.

[Network pharmacology-based study on mechanism of Yuanhu Zhitong Dropping Pills in the treatment of primary dysmenorrhea].

This study was designed to explore the mechanism of Yuanhu Zhitong Dropping Pills(YHZT) in the treatment of primary dysmenorrhea by pharmacological network technology and establish a research approach of "Compound-Target-Pathway-Disease" network. Twenty-eight compounds absorbed into blood including 22 prototype and 6 metabolites of YHZT were submitted to Pharm Mapper and Kyoto Encyclopedia of Genes and Genomes(KEGG) bioinformatics softwares to predict the target proteins and related pathways respectively. The network of "Compound-Target-Pathway-Disease" was constructed and analyzed using Cytoscape software.

The screening research of anti-inflammatory bioactive markers from different flowering phases of Flos Lonicerae Japonicae.

Flos Lonicerae Japonicae (FLJ) is an important cash crop in eastern Asia, and it is an anti-inflammatory Traditional Chinese Medicine. There are large variations in the quality of the marketed FLJ products. To find marker ingredients useful for quality control, a tandem technology integrating ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF), principal component analysis (PCA), heat map analysis and hierarchical cluster analysis coupled with a NF-κB luciferase reporter gene assay were used to identify the different ingredients from the green bud, white bud, flowering stage and leaf stages, as well as to screen the anti-inflammatory activity of FLJ compositions.

Absorption, metabolism and effect of compatibility on absorption of qishenyiqi dropping pill.

Qishenyiqi dropping pill (QSYQ), is a traditional Chinese medicine (TCM) prescription for treating heart diseases in China. Knowledge concerning the systemic identification of active compounds and metabolic components of QSYQ is generally lacking. Therefore, it is essential to develop a valid method for the analysis of active compounds of the combined prescription and determination of interactions among the herbs.
