Ti3C2Tx MXene with an ″accordion″ shape was prepared using hydrofluoric acid as an etching agent from the MAX phase (Ti3AlC2) powder. The Ti3C2Tx epoxy resin coatings were prepared using aqueous epoxy resin, aqueous epoxy resin curing agent and Ti3C2Tx as raw materials. The coefficients of friction and wear rates of the coatings were tested by a reciprocating abrasion tester and an optical digital microscope. The morphology and phase composition of the worn surfaces were analysed by scanning electron microscopy, micro confocal laser Raman spectroscopy and X-ray diffractometer to investigate the wear mechanism of coatings. The corrosion resistance of the coating in artificial seawater environment was evaluated by electrochemical workstation. It was shown that Ti3C2Tx epoxy coatings have lower coefficients of friction under artificial seawater environment compared with that under deionized water environment. At the same time, the addition of Ti3C2Tx significantly improves the corrosion resistance of the epoxy resin coating. Ti3C2Tx addition significantly improves the tribological properties of epoxy resin coatings in artificial seawater environments. With the increase of Ti3C2Tx content, both the friction coefficient and wear rate of the coating showed a tendency of decrease firstly and then increase. The lowest friction coefficient and wear rate of the epoxy resin coatings under artificial seawater environment were 0. 13 and 4. 99 × 10-5 mm~3/Nm respectively which were 65. 8% and two orders of magnitude lower than those of the pure epoxy resin coating respectively when the content of Ti3C2Tx was 1. 0 wt% [ABSTRACT FROM AUTHOR]

Objective To investigate the impacts of circular RNA RERE (circRERE) on proliferation, migration and invasion of human multiple myeloma (MM) cell lines by regulating microRNA (miR)-128-3p/serine/threonine protein kinase (WEE1) axis. Methods Normal plasma cells (nPCs) isolated from peripheral blood of healthy subjects and human MM cell lines(U266, RPMI-8226, NCI-H929, LP-1) were cultured. The expressions of circRERE and miR-128-3p were detected by RT-qPCR. The expression of WEE1 was detected by Western blot. After transfection, RPMI-8226 cells were divided into control group (without transfection), sh-circRERE group, sh-NC group, miR-128-3p inhibitor group, inhibitor-NC group, sh-circRERE+inhibitor-NC group and sh-circRERE+miR-128-3p inhibitor group. MTT assay and 5-ethynyl-2'-deoxyuridine (EdU) immunofluorescence staining microscopy were used to detect the proliferation. Migration and invasion were examined by scratch healing experiment as well as Transwell chamber assay. The targeting relationship between miR-128-3p and circRERE or WEE1 was verified though dual-luciferase reporter gene assay. Results Compared with nPCs, the expressions of circRERE and WEE1 in MM cells (RPMI-8226, U266, NCI-H929, LP-1) were increased, and the expression of miR-128-3p was decreased (P＜0.05). Compared with the control group, the proliferation rate, proportion of EdU positive cells, the healing rate of the scratch trauma and the number of invasion of the RPMI-8226 cells in sh-circRERE group were decreased(P＜0.05). However,miR-128-3p inhibitor group showed an opposite result and the difference was statistically significant (P＜0.05). miR-128-3p inhibitor significantly inhibited the effects of sh-circRERE on the proliferation, migration and invasion of RPMI-8226 cells (P＜0.05). Dual luciferase reporter gene experiments showed that circRERE/miR-128-3p and miR-128-3p/WEE1 had a targeting relationship. Conclusions CircRERE may promote proliferation, migration and invasion of RPMI-8226 cells, potentially with a mechanism of regulating miR-128-3p/WEE1 axis. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationship between left ventricular hypertrophy (LVH) diagnosed by Peguero-Lo-Presti index and recurrence of paroxysmal atrial fibrillation (AF) after radiofrequency ablation. Methods A total of 652 patients with paroxysmal atrial fibrillation who underwent radiofrequency ablation were selected. According to Peguero-Lo-Presti index, patients were divided into the LVH group (167 cases) and the normal left ventricle group (485 cases). Baseline data were collected, and regular follow-up was performed at 3, 6 and 12 months after radiofrequency catheter ablation. The recurrence of AF was assessed. Kaplan-Meier survival curve was used to analyze the recurrence rate of AF in the two groups. Cox proportional hazard model was used to assess risk factors for recurrent atrial fibrillation. Results The median follow-up time was 20.5 (15.0, 26.0) months. A total of 155 patients (23.8%) developed recurrence of AF, including 95 patients in the LVH group and 60 patients in the LVN group. The recurrence rate without AF was significantly lower in the LVH group than that in the LVN group (64.1% vs. 80.4%, Log-rank χ2 =26.361, P＜0.01). After adjusting for age, sex, body mass index, hypertension, diabetes, coronary heart disease, cardiac dysfunction, left anteroposterior and posterior atrial diameter, left ventricular end-diastolic diameter, and left ventricular ejection fraction, LVH diagnosed by Peguero-Lo-Presti index was still a risk factor for recurrent AF [HR (95%CI) : 2.359 (1.663-3.345), P＜ 0.01]. Conclusion In patients with paroxysmal AF, LVH diagnosed by Peguero-Lo-Presti index is a risk factor of AF recurrence after radiofrequency catheter ablation. [ABSTRACT FROM AUTHOR]

BACKGROUND: Over 90% of patients with osteoarthritis suffer from synovial lesions, and the occurrence of synovitis may also promote cartilage degeneration. To explore the potential mechanisms of synovial lesions is beneficial to find precise treatment targets and achieve good long-term prognosis. OBJECTIVE: To identify candidate hub genes in the synovial tissues during the development of osteoarthritis by bioinformatics analysis, and to further provide new insights for osteoarthritis study. METHODS: The osteoarthritis synovial-associated chip data sets GSE82107, GSE12021, GSE55457, and GSE55235 were downloaded from the public database GEO, including 40 cases of osteoarthritic synovial tissue and 36 cases of normal synovial tissue. R software was used to screen differentially expressed genes using Gene ontology function enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and hub genes are selected by STRING online analysis tool and Cytoscape software. RESULTS AND CONCLUSION: Total 447 differentially expressed genes were selected between osteoarthritis and healthy control, including 201 up-regulated and 246 down-regulated genes. These differentially expressed genes were mainly enriched in inflammatory response, regulations of extracellular matrix, collagen, blood vessel development, as well as MAPK signaling pathway, tumor necrosis factor signaling pathway, arachidonic acid metabolism. Eight hub genes were screened by analyzing the protein interactions, which included matrix metalloproteinase 9, interleukin 6, vascular endothelial growth factor A, JUN, prostaglandin peroxide enzyme 2, CXCL8, MYC, epidermal growth factor receptor. The hub genes selected by bioinformatics analysis such as vascular endothelial growth factor A, matrix metalloproteinase 9, JUN, and prostaglandin peroxidase 2 may be biomarkers for the diagnosis of osteoarthritis and potential targets for treatment.

Objective To explore the correlation between the catestatin (CST) level and ventricular arrhythmia (VA) in acute myocardial infarction (AMI). Methods Sixty male rats were randomly divided into sham group (n=20) and AMI group (n=40). Myocardial infarction was produced by ligation of the left anterior descending coronary artery. Thirty-six rats in AMI groupsurvived. Both groups were detected for plasma CST level, ventricular arrhythmia susceptibility, ventricular vulnerable period and effective refractory period so as to evaluate the effect of CST on VA in AMI. Results Compared with that in sham group, LVEF reduced significantly in AMI group (P <0.01), while LVEDD, LVESD and CST increased (P <0.01). After programmed electrical stimulation, in AMI group VA was induced in 31 rats (86.1%) (P<0.01), ventricular vulnerable period extended, and effective refractory period shortened (P<0.01). Logistic regression analysis showed that decreased LVEF and increased CST were the independent risk factors of VA in AMI rats (P<0.01 to P<0.05). Conclusion The CST level is an independent risk factor for VA in AMI; therefore, it can be used to evaluate the prognosis of AMI. [ABSTRACT FROM AUTHOR]
