Quake monitorings are favored for their being in residential areas with well-preserved natural flow systems in Xinyi City＇s Xijiang Hot Springs and Fengshun County＇s Shihu Hot Spring. The hot springs are typical in temperatures and flow rates in southern China＇s Guangdong Province. Physical and chemical conditions deep down in the heat sources are important constraints on earthquake, fluid flow, reactive solute transport and heat transfer, but remain challenging to address via field observations and numerical experiments. In this paper, we made daily and annual observations on flow rates, temperature, and/or aqueous chemistry. We employed strontium isotopes as tracers for the water sources, equilibrium phase diagram for K-feldspar and albite stability, and Na-K-Mg diagram for heat reservoir temperatures. The abundant sulfite content in Xi- jiang Hot Springs is discussed. Our main finding are that the deep fault springs are characterized by low reduction-oxidation potential at around -200- -150 mV and relatively large daily flow variations. The resuits provide scientific background features on the field sites regarding earthquake monitoring and predictions and geothermal reservoir.展开更多

Methods: In the database of Traditional Chinese Medicine Systems Pharmacology (TCMSP), chemical composition and potential targets of Xinyi San were got, and the target genes of rhinitis of Xinyi San were extracted from GeneCards databases. Then we constructed protein-protein interactions (PPI) network of target genes, and then analyzed the Key genes in GO analysis and KEGG analysis. Results: We got 97 components, 53 potential therapeutic targets, 1009 GO items and 92 pathways in our study. The main pathways included Lipid and atherosclerosis, Chemical carcinogenesis-receptor activation, PI3K-Akt signaling pathway, Human cytomegalovirus infection, Prostate cancer, etc. Conclusion: Xinyi San plays a role in treating rhinitis through multiple components, multiple targets and multiple pathways.展开更多

Methods: The effective components and corresponding targets of Xinyi San were collected by TCMSP. The targets of senile rhinitis were collected by the Genecards database. The potential target of Xinyi San in the treatment of senile rhinitis was obtained by Venn analysis. Cytoscape 3.7.2 the software constructs the relationship network model of “disease-single drug-active ingredient-action target”. Protein protein interaction (PPI) network was constructed by using a string database. R4.1.1 software was used for GO function enrichment analysis and KEGG pathway enrichment analysis. Results: In this study, we obtained 158 active ingredients, 40 potential therapeutic targets, 74 GO projects, and 99 pathways. Major pathways include Lipid and atherosclerosis, Chemical carcinogenesis-receptor activation, PI3K-Akt signaling pathway, AGE-RAGE signaling pathway in diabetic complications, Pathways of neurodegeneration-multiple diseases, etc. Conclusion: Xinyi San has the characteristics of multi-component, multi-target, and multi-channel in the treatment of senile rhinitis. This study provides a basis for the in-depth study of Xinyi San.展开更多

Methods: We Screened the active components and targets of Xinyi San by TCMSP database, and disease targets through GeneCards database. We constructed “disease-single drug-component-target” network through software Cytoscape 3.7.2 and constructed PPI network through STRING database. GO function and KEGG pathway enrichment were analyzed to predict its mechanism. Results: We got 162 components, 69 therapeutic targets, 88 GO items and 135 pathways. The main pathways include Lipid and atherosclerosis, Chemical carcinogenesis-receptor activation, Kaposi sarcoma-associated herpesvirus infection, Hepatitis B, Human cytomegalovirus infection, etc. Conclusion: This study preliminarily revealed the active components, targets and pathways of Xinyi San in treating nasal polyposis.展开更多

They were treated with XYA and Salb utamol aerosol (SA) respectively by spray inhalation once a day for seven days a s one therapeutic course to observe the antiasthmatic effect of the treatment. Changes of lung function and the levels of tumor necrosis factor α (TNF-α) , interleukine-2 receptor (IL-2R) and interleukine-8 (IL-8) in serum and sputum were observed before and after treatment using enzyme linked immunos orbent assay (ELISA). Levels of TNF-α, IL-2R andIL-8 in the sputum of part of the patients in the treatment group were also observed.Results: In the treated group, 6 patients had the asthma clinica lly controlled after treatment, 12 were markedly alleviated, 9 alleviated and 3 remained unchanged, while in the control group, the respective numbers were 4, 6 , 15 and 5. The controlled-markedly effective rate of XYA was 60.0%, which wa s significantly better than that of SA (33.3%, P <0.05). The one second forc ed expiratory volume percent (FEV1%) and peek expiratory flow rate (PEFR) improv ed significantly and the levels of TNF-α, IL-2R and IL-8 in serum decr eased noticeably in both groups after treatment ( P <0.05 or P <0.01), but the improvement in the treated group was more significant as compared with tho se in the control group ( P <0.05). The levels of TNF-α, IL-2R and IL -8 in sputum considerably lowered also after XYA treatment ( P <0.01).Conclusion: XYA could regulate the related cytokines in patient s with mild or moderate bronchial asthma, and reduce the releasing of inflammato ry factors, which is consistent with the improvement of lung functions, so as to ease the airway inflammation chiefly exhibited as cell infiltration in bron chi.展开更多
