ABSTRACT
Xiaoer Fupi Granules, a refined version of the classical prescription Shenling Baizhu Powder, has the effect of invigora-ting spleen, replenishing Qi, harmonizing stomach and resolving accumulation and is commonly used to treat Qi deficiency in spleen and stomach, disordered transportation and transformation, and indigestion of children. However, its medicinal constituents and mechanism remain unclear. We studied the main active constituents and action mechanism of Xiaoer Fupi Granules by integrating network pharmacology and prototype constituent analysis in vivo. This study will help to increase the reliability of database analysis results and lay a foundation for precise medication and mining of quality control markers. On the basis of Bioinformatics Analysis Tool for Molecular mechanism of Traditional Chinese Medicine(BATMAN-TCM), the "key chemical constituents-target" network was constructed. Ultra-performance liquid chromatography coupled with linear ion trap-orbitrap mass spectrometry(UPLC-LTQ-Orbitrap-MS) was employed to analyze the absorbed constituents in rat urine and plasma, so as to validate the network. Further, we used BATMAN-TCM to construct the "absorbed constituents-target-pathway" network and explore the functioning mechanism of Xiaoer Fupi Granules. A total of 86 chemical constituents of Xiaoer Fupi Granules were predicted via BATMAN-TCM, among which only 18.6% were detected in rat plasma and urine. Accor-ding to the "absorbed constituents-target-pathway" network, 8 chemical constituents such as stearic acid and caprylic acid capable of regulating gastric acid and insulin secretion may be the critical constituents of Xiaoer Fupi Granules in invigorating spleen and harmonizing stomach. This study identified the critical active constituents and predicted the action mechanism of Xiaoer Fupi Granules, providing the reference for the research on the material basis of Xiaoer Fupi Granules.

Moringa oleifera is a typical tropical multi-functional fast-growing tree species， which is native to India and now widely planted in various tropical regions. After some research and textual research， the records of M. oleifera in China can be traced back to the The Bower Manuscript（volume Ⅱ）（about the 4th—6th century A.D.） unearthed in Kuqa， Xinjiang. M. oleifera contains a variety of active ingredients such as flavonoids， alkaloids， glycosides， organic esters and rich nutrients， which has outstanding medicinal and economic value. As a result， M. oleifera is widely used in food additives， water purification agents， medicine and health care and other fields. In 2012， the Ministry of Health approved M. oleifera as a new resource food. In the current trend of medicine diet and health preservation of traditional Chinese medicine， M. oleifera stands out， which not only expands the direction for the development of health products， but also enriches the development demand of traditional Chinese medicine in our country. However， in our country， the research on M. oleifera is mainly focused on the extraction of chemical components， analysis of nutritional components， consumption and content determination， and the research on its composition and pharmacological action is one-sided. For this purpose， this paper briefly reviewed the active components， hypoglycemic and treatment of diabetic complications， hypolipidemic， antioxidant， anti-inflammatory and applied research status of M. oleifera， and looked forward to the future development and utilization of M. oleifera leaves in China.
ABSTRACT
Integrated pharmacological approach was used to predict the target genes and signal pathways of Xiaoer Fupi granules in the treatment of functional dyspepsia(FD), and the possible mechanism was discussed. The disease target information was collected by the DISEASES and UniProt databases, integrated pharmacological platform of traditional Chinese medicine(TCM-IP) was used to predict chemical composition, target, protein gene ontology(GO) function and Kyoto encyclopedia of genes and genomes(KEGG) pathway, and the networks of candidate target and TCMs-chemical components-core targets-key pathways were constructed. A total of 2 882 potential targets and 96 candidate target pathways were predicted, and β-1,4-galactosyltransferase(β-1,4-GalT) subtypes(B4GALT4, B4GALT2, B4GALT1) and phosphorylated protein kinase C subtype D(PRKCD), adenylate cyclase 2(ADCY2) and other targets were predicted. Some pathways were enriched, such as nervous system, endocrine system, thyroid hormone signaling pathway, long-term depression and other pathways related to FD. It was predicted that Xiaoer Fupi granules for treating FD by regulating gastrointestinal hormones, anti-depression, and regulating nerves and endocrine system. This study provides a basis for the precise clinical application and positioning of Xiaoer Fupi granules, and helps to clarify the mechanism of this drug.
ABSTRACT
Gardeniae Fructus, which is widely used in health foods and clinical medicines, is a type of edible food and medicine. Dictionary of traditional Chinese medicine prescriptions provides good materials for prescription analysis and the R&D of traditional Chinese medicines. The composition regularity of formulae containing Gardeniae Fructus in dictionary of traditional Chinese medicine prescriptions was analyzed on the basis of the traditional Chinese medicine inheritance support system(TCMISS), in order to provide reference for clinical application and the R&D of new drugs. TCMISS was applied to establish a database of prescriptions containing Gardeniae Fructus. The software's frequency statistics and association rules and other date mining technologies were adopted to analyze commonly used drugs, combination rules and core combined formulae containing Gardeniae Fructus. Totally 3 523 prescriptions were included in this study and involved 1 725 Chinese herbs. With a support degree of 352(10%) and confidence coefficient of 90%, 57 most commonly used drug combinations were screened. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. They were used to mainly treat 18 diseases. Gardeniae Fructus have often been combined with herbs for heat-clearing and detoxification, expelling pathogenic wind, relieving exterior syndrome, invigorating the circulation of blood and gas and promoting blood circulation for removing blood stasis to mainly treat jaundice, typhoid, headache and other syndromes.
