RESUMO

Phyllanthus emblica Linn is not only an edible fruit with high nutritional value, but also a medicinal plant with multiple bioactivities. It is widely used in clinical practice with functions of clearing heat, cooling blood, digesting food, strengthening stomach, promoting fluid production, and relieving cough. This review summarized a wide variety of phytonutrients, including nutritional components (mineral elements, amino acids, vitamins, polysaccharides, unsaturated free fatty acids) and functional components (phenolic acids (1-34), tannins (35-98), flavonoids (99-141), sterols (142-159), triterpenoids (160-175), lignans (176-183), alkaloids (184-197), alkanes (198-212), aromatic micromolecules (213-222), other compounds (223-239)). The isolated compounds and the various extracts of P. emblica Linn presented a diverse spectrum of biological activities such as anti-oxidant, anti-cancer, anti-inflammatory, anti-bacterial, hepatoprotective, hypoglycemic, anti-atherosclerosis, neuroprotective, enhancing immunity, anti-fatigue, anti-myocardial fibrosis. The quality markers of P. emblica Linn were predicted and analyzed based on traditional medicinal properties, traditional efficacy, plant genealogy and chemical component characteristics, biogenic pathway of chemical components, measurability of chemical components, transformation characteristics of polyphenolic components, homologous characteristics of medicine and food, compound compatibility environment, and clinical applications. This review also summarized and prospected applications of P. emblica Linn in beverages, preserved fruits, fermented foods, etc. However, the contents of mechanism, structure-activity relationship, quality control, toxicity, extraction, processing of P. emblica Linn are not clear, and are worth further studies in the future.

RESUMO

Ampelopsis grossedentata as a traditional medicinal plant, has many pharmacological effects. Pharmacological effects and possible mechanisms are summarized in this paper based on the research progress of A. grossedentata at home and abroad in recent years, involving digestive system (treating liver injury and improving intestinal flora imbalance), endocrine system (treating hyperglycemia, hyperlipidemia and hyperuricemia), cardiovascular system (treating hypertension, vascular injury, myocardial ischemia-reperfusion injury and myocardial hypertrophy), immune system (anti-inflammatory and anti-tumor) and nervous system (adjuvant treatment for chronic degenerative diseases). By summarizing the animal acute toxicity test, long-term toxicity test and cell test results of A. grossedentata in the literature, it is confirmed that its safety is good.

RESUMO

Some kinds of chronic sialadenitis were recognized during the recent years. They have specific pathogenesis, clinical and histopathologic appearances, and require specific treatment. IgG4-related sialadenitis (IgG4-RS) is one of the immune-mediated diseases, characterized by tumefactive lesions. The incidence of IgG4-RS obviously increased during the past 30 years. The study on the potential relationship between occupational exposure to chemical substances and the incidence of IgG4-RS showed that subjects with occupational exposure to agents known to cause IgG4-RD had an increased risk for IgG4-RS. Surgical excision of involved SMG could not control the disease progression, which is not recommended for treatment of IgG4-RS. The combination of glucocorticoid and steroid-sparing agents is effective for treating IgG4-RS, and restores salivary gland function. Radioiodine induced sialadenitis (RAIS) is one of the common complications of postoperative adjuvant treatment of differentiated thyroid cancer by 131I. The incidence of the disease is related to radiation dosage. Clinically, the patients suffered from swelling and tenderness in the buccal or submandibular regions, especially during the mealtime. Imaging appearances are similar to those of chronic obstructive sialadenitis. Conservative managements, such as gland massage, sialagogues, are the mainstream methods in the treatment of RAIS. Sialendoscopy is feasible for RAIS, but not as effective as conventional obstructive sialadenitis (COS). Therefore the prevention of RAIS is crucial. Eosinophilic sialodochitis (ES) is a new type of chronic inflammatory disease of the salivary gland related to allergy. It has characteristics of swelling of multiple major salivary glands, strip-like gelatinous plugs discharged from the duct orifice of the gland, elevated level of serum IgE and eosinophils in peripheral blood, infiltration of eosinophils and IgE positive plasma cells in the tissues, allergic history, increased expression of allergy-related cytokines, such as IL-4, IL-5, IL-13, and eotaxin, which suggest allergic reactions as a potential pathogenesis of the disease. The clinical, laboratory, histological, and immunohistochemical characteristics of ES are significantly different from conventional obstructive sialadenitis (COS). Therefore, it is suitable to separate ES from COS. Conservative managements, such as self-maintenance therapy and anti- allergic modality are the choices of treatment for ES. Based on the results of our comprehensive studies a new classification of chronic sialadenitis is suggested.

RESUMO

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<sup>-1</sup>, 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.

RESUMO

Sorafenib is slightly absorbed in the gastrointestinal tract due to its poor solubility in water. To improve its absorption, a novel nanoparticulate formulation-nanomatrix was used in the study. The nanomatrix was a system prepared from a porous material Sylysia(®) 350 and a pH sensitive polymer Eudragit(®). The formulations were optimized by orthogonal design (L(9)(3(4))) and their bioavailability were evaluated in rat, comparing to pH-sensitive Eudragit nanoparticles and suspension of sorafenib. In the formulations, the ratio of sorafenib to Eudragit(®) S100 was found to be more important determinant of the sorafenib bioavailability than the ratio of sorafenib to Sylysia(®) 350. As for the bioavailability, the AUC(0-36 h) of sorafenib nanomatrix was 13-33 times to that of sorafenib suspension, but only 16.8% to 40.8% that of Eudragit(®) S100 nanoparticles. This may be resulted from the different drug dispersion degree, release character and bioadhension activity. However, because all the materials used in the nanomatrix formulation are commonly adjuvant, safe, easy to get and cheap, above all, the nanomatrix formulation can solve the stability and scaling up problems in the nanoparticles, it had potential to develop into a product in the future.
