Analysis of Material Basis and Mechanism of Sangjiang Ganmao Injection in Treatment of Common Cold Based on UPLC-Q-Orbitrap HRMS and Network Pharmacology / 中国实验方剂学杂志

Objective:To explore the material basis and mechanism of Sangjiang Ganmao injection （SG） in the treatment of common cold by ultra-performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） and network pharmacology. Method:UPLC-Q-Orbitrap HRMS was used to identify the chemical components of SG with mobile phase of acetonitrile （A）-0.1% formic acid aqueous solution （B） for gradient elution （0-10 min， 4%-15%A； 10-35 min， 15%-30%A； 35-45 min， 30%-33%A； 45-55 min， 33%-60%A； 55-58 min， 60%A）， flow rate of 0.2 mL·min^-1， electrospray ionization （ESI） and scanning range of <italic>m</italic>/<italic>z</italic> 100-1 500 under positive and negative ion modes. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and GeneCards 5.0 database were used to screen and predict the potential targets of chemical components in SG， STRING 11.0 database and Cytoscape 3.7.2 software were used to construct protein-protein interaction （PPI） network model， gene ontology （GO） analysis and pathway analysis were performed on potential targets by Metascape 3.5， Reactome database and Kyoto Encyclopedia of Genes and Genomes （KEGG）， Cytoscape 3.7.2 software was used to build the network of "herbs-ingredients-key targets". Result:A total of 54 components in SG were identified， and 80 potential targets of SG for treatment of common cold were predicted and screened based on this. SG exerted therapeutic effects by acting on targets such as interleukin （IL）-6， tumor necrosis factor （TNF） and IL-10， and signaling pathways such as IL-17 signaling pathway， TNF signaling pathway and interaction of cytokine receptors. Conclusion:SG may interfere with the expression of inflammatory cytokines by acting on related targets and pathways such as inflammation and immune system， and regulate the immune function of the body as a whole， thereby exerting a therapeutic effect.

Grading standard of processed Curcumae Radix / 中国中药杂志

As one of the three pillars of Chinese medicine industry, traditional Chinese medicines prepared in ready-to-use forms are important raw materials for clinical medication and production of Chinese patent drugs. By considering the literature of Curcumae Radix, a multi-source Chinese herb and the situation of market investigation, the modern evaluation method based on traditional grading was introduced for comprehensive evaluation of the processed Curcumae Radix. The correlation between traditional grading method and modern evaluation index was explored to establish the grading standard of Curcumae Radix. According to the comprehensive evaluation, Curcumae Radix was divided into four grades: superior, first, second and third grades under the guidance of the theory of traditional Chinese medicine. This study provides a new idea for the grading of multi-source processed Chinese medicine, achieving high quality and good price, which is helpful to improve the clinical efficacy.
