一种整体壁板填料辅助滚弯成形过程中填料作用机理

研究一种2A12铝合金整体壁板的聚丙烯填料辅助滚弯成形工艺,结合力学分析、数值模拟和实验验证,揭示填料的作用机理。结果表明,整体壁板筋条与蒙皮处的中性层位置差导致其成形后母线直线度不达标,填料可以降低这种中性层位置差。当填料与筋条有一定宽度间隙(1~3 mm)时,可以避免填料卷曲和筋条失稳。而填料和筋条的高度间隙决定填料可被压缩程度,当填料在压缩后仍高于筋条(1 mm)时,可以达到最佳的压力传递效果。填料的弹性模量在一定范围内时(450~1300 MPa),对整体壁板的成形精度影响不大。但填料弹性模量较低时(50 MPa),填料传递的压力不足;填料弹性模量较高时(20 GPa),整体壁板弯曲变形受限。实验后壁板母线直线度的测量结果验证了填料的作用机理。

Background:To evaluate the mechanism of Chinese patent drug Xuebijing(XBJ)injection in the treatment of a new coronavirus disease 2019(COVID-19)based on network pharmacology and molecular docking technology.Methods:The TCMSP database was employed to collect and screen the active ingredients of the Chinese herb contained in the XBJ injection.The GeneCards database and STRING database were applied to collect and expand the targets of COVID-19 and compare and screen the related targets of COVID-19 by XBJ injection.Cytoscape was employed to build a network connecting Chinese medicine,compounds,targets,disease,and topology analysis was performed via the Network Analyzer to screen the key ingredients and targets.The software of Schrödinger molecular docking was used to verify the binding activity of the key ingredients of XBJ injection and the key targets of COVID-19.Metascape platform and DAVID database were utilized to conduct Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes analysis on the key targets of COVID-19 treated by XBJ injection.Results:Eight key compounds and 15 key targets were screened and verified by molecular docking;these key compounds included luteolin,quercetin,baicalein,and kaempferol.The key targets included DPP4,AR,ESR1,CALM1,and protein kinase 1.Gene Ontology analysis involved an apoptosis and hypoxia reaction and the changes in blood vessel morphology.Kyoto Encyclopedia of Genes and Genomes analysis involved signaling pathways of hypoxia inducible factor-1,VEGF,and PI3K/AKT/NF-κB.Conclusion:The mechanism of XBJ injection when used to treat COVID-19 should be further investigated as the key compounds in XBJ regulated the expression of key targets such as protein kinase 1,VEGF-A,B-cell lymphoma-2,and TNF,which affected the COVID-19 receptors such as angiotensin-converting enzyme 2 and signaling pathways like hypoxia inducible factor-1,PI3K-Akt,and NF-κB,which alleviated the inflammation,respiratory distress,and hypoxia caused by COVID-19 infection.

Spastin interacts with collapsin response mediator protein 3 to regulate neurite growth and branching

Cytoskeletal microtubule rearrangement and movement are crucial in the repair of spinal cord injury.Spastin plays an important role in the regulation of microtubule severing.Both spastin and collapsin response mediator proteins can regulate neurite growth and branching;however,whether spastin interacts with collapsin response mediator protein 3(CRMP3)during this process remains unclear,as is the mechanism by which CRMP3 participates in the repair of spinal cord injury.In this study,we used a proteomics approach to identify key proteins associated with spinal cord injury repair.We then employed liquid chromatography-mass spectrometry to identify proteins that were able to interact with glutathione S-transferase-spastin.Then,co-immunoprecipitation and staining approaches were used to evaluate potential interactions between spastin and CRMP3.Finally,we co-transfected primary hippocampal neurons with CRMP3 and spastin to evaluate their role in neurite outgrowth.Mass spectrometry identified the role of CRMP3 in the spinal cord injury repair process.Liquid chromatography-mass spectrometry pulldown assays identified three CRMP3 peptides that were able to interact with spastin.CRMP3 and spastin were co-expressed in the spinal cord and were able to interact with one another in vitro and in vivo.Lastly,CRMP3 overexpression was able to enhance the ability of spastin to promote neurite growth and branching.Therefore,our results confirm that spastin and CRMP3 play roles in spinal cord injury repair by regulating neurite growth and branching.These proteins may therefore be novel targets for spinal cord injury repair.The Institutional Animal Care and Use Committee of Jinan University,China approved this study(approval No.IACUS-20181008-03)on October 8,2018.

Expression profile analysis to identify potential gene changes induced by dexamethasone in the trabecular meshwork

AIM:To investigate potential gene changes in trabecular meshwork(TM)induced by dexamethasone(DEX)in steroidinduced glaucoma(SIG).METHODS:The expression data of 24 cases from a public functional genomics data were sorted to identify the mechanisms of action of DEX on the TM.The relationships of the differentially expressed genes(DEGs)were enriched using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.In addition,the hub genes were screened by the Search Tool for the Retrieval of Interacting Genes Database(STRING)and Cytoscape tools.Finally,human TM cells(HTMCs)were treated with DEX to preliminarily explore the function of hub genes.RESULTS:Totally 47 DEGs,including 21 downregulated and 26 upregulated genes were identified.The primary enriched results of the DEGs consisted of inflammatory response,extracellular matrix(ECM),negative regulation of cell proliferation,TNF signalling pathway and the regulation of tr yptophan channels by inflammator y mediators.Subsequently,pro-melanin-enriched hormone(PMCH)and Bradykinin B1 receptor(BDKRB1)were screened as hub genes.It is verified in GSE37474 data set.Western blot and quantitative real-time polymerase chain reaction(q PCR)results showed that protein and RNA expression levels of BDKRB1 were significantly decreased after DEX treatment,while PMCH was not significantly changed.CONCLUSION:BDKRB1 may be a key gene involved in SIG onset,providing a suitable therapeutic target for improving the prognosis of SIG patients.
