RNA–binding motif protein 24 (RBM24) acts as a multifunctional determinant of cell fate, proliferation, apoptosis, and differentiation during development by regulating premRNA splicing and mRNA stability. It is also implicated in carcinogenesis, but the functions of RBM24 in bladder cancer (BC) remain unclear. In the present study, we revealed that RBM24 was upregulated in BC tissues. Importantly, we found that a higher level of RBM24 was correlated with poor prognosis in BC patients. Overexpression of RBM24 promoted BC cell proliferation, while depletion of RBM24 inhibited BC cell proliferation in vivo and in vitro. Mechanistically, RBM24 positively regulated Runx1t1 expression in BC cells by binding to and enhancing Runx1t1 mRNA stability. Furthermore, Runx1t1 in turn promoted RBM24 expression by interacting with the transcription factor TCF4 and suppressing the transcription of miR-625-5p, which directly targets RBM24 and suppresses RBM24 expression. RBM24-regulated BC cell proliferation was moderated via the Runx1t1/TCF4/miR-625-5p feedback loop. These results indicate that the RBM24/Runx1t1/TCF4/miR-625-5p positive feedback loop participates in BC progression. Disruption of this pathway may be a potential therapeutic strategy for BC treatment.

CeO2/Al2O3 catalysts prepared by three methods were investigated for selective reduction of NO with NH3. It was found that the catalyst prepared by the single step sol–gel method had the best SCR activity and SO2 resistance performance. From the results of BET, XRD, TPD and TPR, it can be concluded that large surface area, strong interaction, highly dispersed nano-crystalline ceria, high NH3 adsorption capacity and good redox ability might be the main reasons for the excellent performance of CeO2/Al2O3catalyst prepared by the single step sol–gel method.
Effect of Cu doping on the SCR activity of CeO2 catalyst prepared by citric acid method

CeO2–CuO catalyst prepared by citric acid method was investigated for selective catalytic reduction of NO with NH3. The activity of the CeO2 catalyst was enhanced about 8–27% in the temperature range of 125–225 ℃ at a space velocity of 28,000 h 1 by the addition of Cu. It was found that the state of Cu species had great impact on the SCR performance of CeO2–CuO catalyst. Cu2+ can enhance the low temperature activity of SCR reaction, while CuO would promote NH3 oxidation before SCR reaction at high temperature, which would cause the decrease of its high temperature SCR activity.

In this paper, a new series of phase change materials (PCMs) composed of capric acid/ethylene-vinylacetate/graphene (CA/EVA/GR) were prepared and thermal properties were investigated using moleculardynamics simulation. The composite PCMs were characterized by Fourier transform infraredspectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanningcalorimetry (DSC) and thermal conductivity measurement. FT-IR, XRD and SEM results manifest that CAcan be successfully wrapped by EVA and GR additives, and there is no chemical reaction between CA, EVAand GR. DSC results indicate that adding GR into CA/EVA can result in composite PCMs maintain the highlatent heat, while too much GR will cause a significant reduction in latent heat. Thermal conductivityobtained from experimental tests reveal that GR can gradually enhance the thermal conductivity of CA/EVA with increasing dosage of GR. The experimental results of thermal conductivity fall close to that ofmolecular dynamics (MD) simulation at GR dosages below 1.8 wt%, but the experimental results present atrend which is contrary to MD simulation at higher GR dosages. The mean square displacement (MSD)results manifest that composite PCMs containing 1.8 wt% GR has the highest diffusion coefficient, whilehigher GR dosage will reduce the diffusion coefficient gradually.

Acute graft-versus-host disease (GVHD) following liver transplantation is a rare but fatal complication. The correct diagnosis and management of GVHD after liver transplantation are still major challenges. Herein, we reported successful salvage treatment of acute GVHD by withdrawal of immunosuppression in a patient who presented with fever, skin rashes, and decreased blood cell counts after liver transplantation. This case highlights the need for awareness of drug-induced liver injury if liver function tests are elevated during treatment, especially in patients taking multiple potentially hepatotoxic drugs, such as broad-spectrum antibiotics. When occurs, an artificial liver support system is a useful tool to provide temporary support of liver function for the patient in the event of drug-induced liver injury.
Electronic Structures and Optical Properties of CuSCN with Cu Vacancies

Based on density functional theory (DFT) within the generalized gradient approximation (GGA) using the CASTEP code, we calculated the formation energy of a Cu vacancy, as well as the band structure and the optical properties of β-CuSCN with Cu vacancies. Removal a Cu atom from the 32-site and the 72-site supercell results in an enlargement of the band-gap and a slight relaxation in the lattice parameter. An accepter level above the valence band maximum is observed in the 32-site supercell with a Cu vacancy, which results in the onset of a small absorption pre-peak at 0.65 eV.

A case of adrenal ganglioneuroblastoma is presented here. This adrenal ganglioneuroblastoma was found in a 27-yearold female 7 months after delivery. CT clarified that the tumor originated retroperitoneally and was large in size (11.4 cm × 9.4 cm). The tumor was surgically removed together with pancreatic body and tail, left kidney and spleen, and pathological diagnosis was adrenal ganglioneuroblastoma-intermixed. Adrenal ganglioneuroblastoma is extremely rare in adults, with only about 9 cases documented including this case.
