RESUMEN
Objective:To explore the similarities and differences between Opening Xuanfu therapy and Qingreliangxue therapy in the treatment of psoriasis based on the Network Pharmacology.Methods:The active ingredients and protein targets of the representative Traditional Chinese Medicine contained in drugs Qingreliangxue therapy and Opening Xuanfu therapy were screened out by Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP), Encyclopedia of Traditional Chinese Medicine (ETCM) and Traditional Chinese Medicine Integrated Database (TCMID). The Targets of psoriasis were collected by GeneCards and OMIM databases. The intersections of component targets and disease targets were obtained by Venny 2.1.0, and then the protein-protein interaction (PPI) was constructed by String Platform and Cytoscape 3.9.0 to screen out the key targets in the two therapies that could treat psoriasis. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed via the Metascape platform. The potential advantages of opening Xuanfu therapy in the treatment of psoriasis comorbidities are found out by using Venny and Cytoscape to compare the differences and visually analyze the above results.Results:8 ingredients are with the same effect and 73 ingredients are different in these two therapies. There are 43 identical and 15 different potential targets in these two therapies..10 representative key targets in each of the two therapies were obtained by PPI network analysis, including 7 identical key targets, namely HIF1A, MYC, CCND1, FOS, IL6, PPARG, NFKBIA, and 6 different targets. Go enrichment results show that there are 10 same biological processes in the first 20 articles of the two the therapies, including the response to external stimuli, the regulation of cell adhesion, the response to steroid hormone, the response to injury, the negative regulation of cell differentiation, the response to growth factors and metabolism of reactive oxygen species. KEGG enrichment results of the first 20 pathways in the two therapies show that there are 8 same pathways, including cancer-related pathways, fluid shear stress and atherosclerosis, MAPK signaling pathway, p53 signaling pathway, transcriptional imbalance in cancer and cholinergic synapse.Conclusion:Qingreliangxue therapy in the treatment of psoriasis mainly plays the role of antioxidant, anti-inflammatory, anti-proliferative and immune-regulating effects. The Opening Xuanfu therapy in the treatment of psoriasis mainly plays the role of regulating lipid metabolism, anti-inflammatory, regulating cell apoptosis, anti-oxidation, anti-proliferation, regulating angiogenesis and abnormal morphology.
RESUMEN
Acid deposition causes carbonate dissolution in watersheds and leads to profound impacts on water chemistry of lakes. Here, we presented a detailed study on the seasonal, spatial, and vertical variations of calcium and magnesium species in the overlying water, interstitial water, and sediment profiles in eutrophic Taihu Lake under the circumstance of regional acid deposition. The result showed that both the acid deposition and biomineralization in Taihu Lake had effects on Ca and Mg species. In the lake water, calcium carbonate was saturated or over-saturated based on long-term statistical calculation of the saturation index (SI). On the sediment profiles, significant difference in Ca and Mg species existed between the surface sediment (0-10 cm) and deeper sediments (>10 cm). The interstitial water Ca2+ and Mg2+, ion-exchangeable Ca and Mg in the surface sediment were higher than those in the deeper sediment. In the spring, when the acid deposition is more intensive, the acid-extracted Ca and Mg in the surface sediment were lower than that in the deeper sediment in the northwest lake, due to carbonate dissolution caused by the regional acid deposition. Spatially, the higher concentration of acid-extracted Ca and Mg in the northwest surface sediment than that in the east lake was observed, indicating the pronounced carbonate biomineralization by algae bloom in the northwest lake. Statistical analysis showed that acid deposition exerted a stronger impact on the variation of acid-extracted Ca and Mg in the surface sediment than the biomineralization in Taihu Lake. For the total Ca and Mg concentration in the spring, however, no significant change between the surface and deeper sediment in the northwest lake was observed, indicating that the carbonate precipitation via biomineralization and the carbonate dissolution due to acidic deposition were in a dynamic balance. These features are of major importance for the understanding of combined effects of acid deposition and eutrophication on freshwater lakes.
