Objective:To explore the mechanism of Xuanfei Dahe Decoction in treating asthmatic mice through network pharmacology and animal experiments.Methods:The active components and their targets of Xuanfei Dahe Decoction were retrieved from TCMSP, and the asthma targets were obtained by searching the GeneCards, DisGeNet, OMIM, TTD and DrugBank databases. PPI network of intersection targets was constructed using string database and Cytoscape 3.9.0 software. Go function and KEGG pathway enrichment were analyzed by metascape database. The mice were divided into a blank group of 6 mice and a model group of 30 mice according to the random number table method. The asthma model was prepared in the model group. Totally 30 successfully modeled mice were divided into the model group, the dexamethasone group, and Xuanfei Dahe Decoction low-, medium- and high-dosage groups according to the random number table method, with 6 mice in each group. On the 5th day, gavage was initiated. Xuanfei Dahe Decoction low-, medium- and high-dosage groups were respectively gavaged with Xuanfei Dahe Decoction liquid at concentrations of 6.84, 13.68 and 27.36 g/kg. The dexamethasone group was gavaged with dexamethasone acetate tablets at concentrations of 2.73 mg/kg. The blank group and the model group were gavaged with the same volume of sterile normal saline once a day for 14 consecutive days. The pathological changes of lung tissue were observed by HE staining, the level of serum IL-17 was detected by ELISA, and the expression of IL-17 in lung tissue was detected by immunohistochemistry.Results:120 asthma targets and 13 key targets were obtained from Xuanfei Dahe Decoction. Pathway enrichment analysis suggested that IL-17 signaling pathway was one of the key pathways. Compared with the model group, the levels of IL-17 in the serum of the low-dose, medium-dose and high-dose Xuanfei Dahe Decoction groups and the expression of IL-17A in the lung tissue of the medium-dose Xuanfei Dahe Decoction group decreased ( P<0.05). Conclusion:Xuanfei Dahe Decoction may treat asthma by restrain airway inflammation mediated by Th17/IL-17.

The symptoms of allergic diseases are complex and changeable, and the pathogenesis is complex and difficult to distinguish, and the prevalence of allergic diseases has gradually increased in recent years. Due to the relative limitations of Western medical treatment, in order to further meet the clinical treatment goals, the "lung being responsible for regulating visceral activities" is now used as the theoretical basis, combined with modern medicine, to explore the pathogenesis and etiological mechanism of this disease. Based on the classics, it is proposed that allergic diseases have four characteristics: "onset of allergies, seasonality of disease onset, diversity of symptoms, and recurrence of recovery", and summarized the etiology and pathogenesis as "stagnation of incubative pathogenic factors and disharmony between the nutritive and defensive levels, imbalance of waterways and obstruction of phlegm and dampness, a dysfunction in the pivotal qi flow leading to malnourishment of the skin and hair, the intermingling of cold and heat leads to the dysfunction of the orifices, a disorder of the blood-governing organs leads to extravasation of blood", and advocated that the treatment should take into account the symptoms, syndromes, viscera, and seasons, and clarify the syndromes, which would provide a new research idea for the exploration of the TCM connotation of this disease.

Objective To investigate the effects of downregulating microRNA(miR)-550a-5p on the proliferation,migration and invasion of non-small cell lung cancer(NSCLC)and to explore its mo-lecular mechanisms.Methods The miR-550a-5p inhibitor and its negative control(inhibitor NC),as well as small interfering RNA targeting scavenger receptor class A member 3(si-SCARA3)and its negative control(si-NC)were individually or co-transfected into A549 cells.These cells were desig-nated as inhibitor NC group,miR-550a-5p inhibitor group,miR-550a-5p inhibitor+si-NC(co-trans-fection)group and miR-550a-5p inhibitor+si-SCARA3(co-transfection)group.Cell proliferation was assessed by CCK-8 assay;colony formation ability was evaluated using a plate cloning method;cell migration and invasion were detected by scratch assay and Transwell chamber assay,respectively;levels of matrix metalloproteinase(MMP)-2 and MMP-9 in the supernatant of A549 cells were measured by enzyme-linked immunosorbent assay(ELISA);apoptosis levels were determined by Annexin V/PI double staining.Results Compared with adjacent normal tissues,the expression level of miR-550a-5p was increased,while SCARA3 mRNA expression was decreased in NSCLC tissues(P＜0.05).Dual-luciferase reporter assays confirmed that miR-550a-5p directly targeted SCARA3.Compared with the inhibitor NC group,cell proliferation rate,colony formation number,migration and invasion ability of the miR-550a-5p inhibitor group decreased,apoptosis rate increased(P＜0.05).Compared with the inhibitor NC group,the expression levels of MMP-2 and MMP-9 in cell supernatant of the miR-550a-5p inhibitor group were decreased,and the expression levels of SCARA3 protein were increased(P＜0.05).Compared with the miR-550a-5p inhibitor group or the miR-550a-5p inhibitor+si-NC group,cell proliferation rate,clonal colony formation number,migration and invasion ability of the miR-550a-5p inhibitor+si-SCARA3 group were increased,and apoptosis rate was decreased(P＜0.05).Compared with the miR-550a-5p inhibitor group or the miR-550a-5p inhibitor+si-NC group,the miR-550a-5p inhibitor+si-SCARA3 group showed in-creased expression levels of MMP-2 and MMP-9 in the cell supernatant and decreased SCARA3 pro-tein expression levels(P＜0.05).Conclusion Downregulation of miR-550a-5p inhibits the prolif-eration,migration and invasion of NSCLC cells,and promotes apoptosis,possibly through upregulat-ing SC AR A3 expression.
