Encapsulation of ionic liquid, phosphotungstic acid inside the nanocages of MIL-101(Cr): Effective and reusable catalyst for efficient solvent-free oxidative desulfurization from fuel oil

Oxidative desulfurization from fuel oil is one of the important methods for deep desulfurization.The development of efficient oxidative desulfurization catalysts is crucial for improving the desulfurization performance.Successful encapsulation of phosphotungstic acid(HPW)and ionic liquid(BMImBr)inside the mesoporous cages of MIL-101(Cr)was accomplished through a combination of“bottle around ship”and“ship in bottle”methods.The obtained BMImPW@MIL-101(Cr)composite was characterized by XRD,FTIR,BET,SEM,XPS and ICP methods.Results indicated that the BMImPW@MIL-101(Cr)composites with PW^(3−) loading of 23.1–50.7 wt%were obtained,demonstrating that the“bottle around ship”method is beneficial to make full use of nanocages of MIL-101(Cr)to obtain expected high loading of active PW^(3−) .The BMImPW@MIL-101(Cr)exhibits excellent reusability with no evidence of leaching of active PW^(3−) and BMIm^(+),and well-preserved structure after successive cycles of regeneration and reuse.The significantly improved stability of BMImPW@MIL-101(Cr)as compared to HPW@MIL-101(Cr)is possibly because the leaching of the active PW^(3−) −sites can be greatly suppressed by forming large size of BMImPW owing to introduction of BMIm^(+)cation.The BMImPW@MIL-101(Cr)exhibited excellent catalytic activity for solvent free oxidative desulfurization of refractory sulfides.The enhanced oxidative desulfurization activity as compared to HPW@MIL-101(Cr)can be explained by the intimate contact of sulfides with active PW^(3−) sites owing the strong attraction of BMIm^(+)cation with the sulfides.

Clinical Research progress of traditional Chinese medicine in treating esophageal cancer

Esophageal cancer is one of the most common malignant tumors in the world. In recent years, the incidence and mortality of esophageal cancer have increased year by year, which has seriously threatened human health. Surgery, chemotherapy and radiotherapy, as the primary treatments of Western medicine, have achieved specific results in the clinic, but each has its limitations, this is mainly related to their side effects. The diversified treatment methods of traditional Chinese medicine have visible clinical effects, especially in terms of reducing toxicity and increasing efficiency. This present review reviews the research progress of esophageal cancer in terms of traditional Chinese medicine treatment, including the application of Chinese medicine extract, Chinese herbal compound, Chinese patent medicine and TCM external treatment in clinical practice, may provide valuable information for the adjuvant treatment of esophageal cancer with traditional Chinese medicine.

Effect of Sini Decoction plus Ginseng on COVID-19 based on network pharmacological analysis

Objective:To explore the effect of Sini Decoction plus Ginseng on COVID-19 based on network pharmacological analysis.Methods:TCMSP platform was used to search the compounds of Sini Decoction plus Ginseng with oral bioavailability(OB)≥30%and drug-likeness(DL)≥0.18,and the results were input into the UniProt database and converted into standard target names;Genecards and OMIM database were used to find COVID-19 target,and the intersection targets were obtained and Venn diagram was drawn.Cytoscape 3.7.2 was applied to make the network diagram of composition-disease-target;The interaction database platform-String was used to analyze the target protein interaction,and the data were input into the software of Cytoscape 3.7.2 to make the network diagram;David database was used to analyze the accumulation of Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathways of drug-disease intersection targets.The component target pathway network was constructed by using Cytoscape 3.7.2.Results:Altogether,112 active components of Sini Decoction plus Ginseng were screened,corresponding to 234 targets.Besides,261 COVID-19 targets were obtained after screening,and the Venn map showed that 50 targets were intersected.Quercetin,kaempferol,naringenin,andβ-sitosterol were found to have higher moderate values shown by the component-disease-target network.The target proteins with high PPI network analysis value were IL-6,MAPK8,MAPK3,MAPK1,TP53,TNF,and CASP3.GO enrichment function analysis showed that 341 biological processes,33 cell components,and 50 molecular functions were involved,which showed inflammatory reaction,cell response to lipopolysaccharide,exogenous apoptosis signal pathway,positive regulation of RNA polymeraseⅡpromoter transcription,cytokine activity,chemokine activity,heme binding,and other biological processes.KEGG signaling pathway enrichment function analysisshowed that there were 112 signaling pathways.It included TNF signaling pathway,tuberculosis,influenza A,PI3K Akt signaling pathway,HIF-1 signaling pathway,and Toll-like receptor signaling pathway.According to the component-target-pathway network diagram,quercetin,kaempferol,naringenin,andβ-sitosterol in Sini Decoction plus Ginseng may act on IL-6,MAPK8,MAPK3,MAPK1,TP53,TNF,CASP3,and other targets through TNF signaling pathway,MAPK signaling pathway,Tolllike receptor signaling pathway,PI3K-Akt signaling pathway,and HIF-1 signaling pathway.Conclusion:Sini Decoction plus Ginseng can affect COVID-19 through multiple active components,multiple targets,and multiple pathways.

Target gene prediction and functional analysis of miRNAs differently expressed in colon cancer primary tumors to metastases formed in the liver

Background:Colon cancer is one of the main tumor-related causes of death worldwide and now surgical resection is still the most effective method for the treatment of colon cancer.However,many colon cancers currently lose the opportunity for surgical treatment because of liver metastases.The possible molecular mechanism of liver metastasis of colon cancer can provide ideas for the prevention and treatment of liver metastasis colon cancer.Several studies have recently indicated the regulatory effects of microRNAs(miRNAs)in cancer metastasis.Bioinformatics methods were used to analyze the differentially expressed miRNAs in primary colon cancer tissues and liver metastases.Then the target genes of differentially expressed miRNAs were predicted.By analyzing the biological processes and signaling pathways that the target gene may participate in,we infer the possible molecular mechanisms of liver metastasis of colon cancer and the effects of target genes on prognosis of patients were explored.Methods:The chip data GSE98406 was selected and differentially expressed miRNAs between primary colon cancer and liver metastatic colon cancer were explored by Morpheus.TargetScan and miRanda were used to predict target genes of differentially expressed miRNAs.The gene oncology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were performed to analyze the biological processes and possible signaling pathways the target genes involved in.Protein-ptotein interaction analysis was performed by String and Cyotscape,the interactions among target genes and hub genes were analyzed.Finally,we explored the effects of differentially expressed miRNAs and their target genes on the prognosis of colon cancer patients.Results:Two differentially expressed miRNAs were screened out,of which miR-122 was upregulated more than 2 folds and miR-143 was downregulated more than twofold in liver metastatic colon cancer.Target genes of miR-122 and miR-143 were mainly involved in energy metabolism.The major signaling pathways involved are epithelial-mesenchymal transition pathways.Ten hub genes were selected by protein interaction analysis.Among them,KRAS,CDK1,CREB1,CS,PC,RAB7A,and CANX were highly expressed in tumor tissues,and CALM1 and MAPK7 were lowly expressed in tumor tissues.The results showed that reduced expression of CS and PC reduced survival of patients with colon cancer.However,the impact of miR-122 and mi-143 on the prognosis of patients with colon cancer is not clear.Conclusion:Differentially expressed miRNAs mainly affect the expression of target genes involved in energy metabolism and cellular transformation in colon cancer.Intracellular metabolic activity is the center of cellular activity,the treatment of metabolic processes in tumor cells may be a new idea for the treatment of tumors.
