Explore the rule and mechanism of psoriasis herbal treatment based on data mining and network pharmacology

Background:To mine the rules for psoriasis herbal treatment with the traditional Chinese medicine inheritance system V2.5 and explore the possible mechanism with network pharmacology.Methods:Collect oral administrations for psoriasis treatment in the national patent network in CNKI database;then enter them into the traditional Chinese medicine inheritance system V2.5 to do data mining using the methods of frequency analysis,association rules and entropy clustering of complex systems.KEGG pathway analysis was performed by BATMAN-TCM(an online analysis tool)and the potential signaling pathways of core drugs compatibility to treat psoriasis were revealed.Results:We screened out 349 prescriptions,involving 401 drugs,39 drugs with frequency of use≥30,and 52 commonly used drug pairs.Core compatibility herbs in clinical treatment of psoriasis,Shengdi(Radix rehmanniae),Mudanpi(Cortex moutan),Danggui(Radix angelicae sinensis)which potential signaling pathways were neuroactive ligand-receptor interaction,oxidative phosphorylation,adipocytokine signaling pathway and fatty acid degradation.Conclusion:In the national patent network,oral traditional prescriptions of traditional Chinese medicine show that the basic therapies are nourishing and activating blood,detoxification and cooling the blood and dispelling wind and arresting itching.Interventions in signaling pathways like neuroactive ligand-receptor interaction,oxidative phosphorylation,adipocytokine signaling pathway and fatty acid degradation might be the mechanism to achieve.

Conjugated organic component-functionalized hourglass-type phosphomolybdates for visible-light photocatalytic Cr(VI)reduction in wide pH range

Abstra ct Utilizing efficient and durable photocatalysts for the removal of carcinogen Cr(Ⅵ)in wide pH water environment is of great significance for environment remediation.Herein,three conjugated organic component-functionalized hourglass-type phosphomolybdate hybrids with the formulas(H_(2)DBQ)[Fe(-H_(2)O)_(3)]_(2){Fe[P_(4)Mo_(6)0_(31)H_(7)]_(2)}·7H_(2)O(1),(H_(2)DBQ)_(2)(H_(2)DBP)[Fe(H_(2)O)_(4)]{Fe[P_(4)Mo_(6)O_(31)H_(7)]_(2)}·4H_(2)O(2),(H_(2)DBP)_(2){Fe[P_(4-)Mo_(6)O_(31)H_(9)]_(2)}·10H_(2)O(3)(DBQ=2,2'-dimehyl-6,6'-biquinoline;DBP=4,4'-diaminobiphenyl)were synthesized via hydrothermal method as photocatalysts for reducing Cr(Ⅵ)under visible light illumination.Structure analysis showed that hybrids 1-3 consist of hourglass-type[Fe(P_(4)Mo_(6)O_(31)H_(6))_(2)]^(10)-(abbr.Fe{P_(4)Mo_(6)}_(2))poly anionic clusters functionalized with different proportional of conjugated organic components(DBQ and DBP)effectively regulated their visible-light absorption capabilities and electron structures,which could be employed to reflect the structure-activity relationship of materials.When used as catalysts for reducing Cr(Ⅵ),hybrids 1-3 displayed distinct photocatalytic activities with Cr(Ⅵ)removal efficiencies of 91%,86%and 81%with only 10 W of white light being used as illumination,which are superior to that of pristine Fe{P_(4)Mo_(6)}_(2) salt(62%).Moreover,hybrid 1 also maintained high Cr(Ⅵ)removal efficiencies above~85%and high structural stabilities in solutions with wide pH ranges of2.5-10.0.Mechanism investigation showed that the higher organic component conjugation levels could promote the optic al absorption and facilitate the electron transfer between Fe{P_(4)Mo_(6)}_(2) and org anic components,thus resulting in effective Cr(Ⅵ)reduction photocatalytic efficacy.This work provides a viable way to design the photocatalysts based on polyoxometalates for removing wastewater pollutants.
