A novel symmetric conjugated oligo(phenylene-ethynylene) COPE) linear molecule (1,4-bis(4-aminophenylethynyl)benzene): BAB) was synthesized by Sonogashira cross-coupling reactions. The structure and purity of the compound were confirmed by (1)H NMR, (13)C NMR and infrared (IR) and mass spectrometry (MS). The electrochemical oxidation process and mechanism of BAB were investigated via in situ Fourier transform infrared (FTIR) spectroelectrochemistry and electrochemical quartz crystal microbalance (EQCM). The electrochemical oxidation mechanism of BAB was proposed. The studies revealed that the BAB concentration and oxidation potential had a significant influence on the growth of the polymer film. A densely packed polymer film, which exhibited nonelectroactivity, was formed when a high monomer concentration and a high oxidation potential were used. When the electropolymerization of BAB was conducted at a lower concentration, a new pair of redox peaks appeared, and the resultant thin film had better electroactivity. The in situ FTIR studies confirmed that BAR could be electro-oxidized into radical cations and then electropolymerized via para (N-N) and/or ortho (N-C) coupling reactions to form polymers with a larger conjugated pi-electron system. The surface morphology of the poly-BAB was also investigated with atomic force microscopy (AFM) and scanning electron microscopy (SEM). (C) 2010 Elsevier Ltd. All rights reserved.

Jie Zhao, Jun Ai, Chao Mo, Wei Shi, LiFeng Meng

Summary: This study evaluated and compared the efficacy of seven Chinese patent medicines (CPMs) combined with ACEI or ARB on early diabetic kidney disease (DKD) using a Bayesian network meta-analysis. The results indicated that UCG + ACEI/ARB, JSB + ACEI/ARB, CXC + ACEI/ARB, and HKC + ACEI/ARB may be the preferred interventions for reducing UAER, 24-h UTP, SCr, and BUN levels, respectively. BLC + ACEI/ARB showed significant effects on lowering TRIG, TC, and CRP levels. However, more high-quality research is needed to confirm these findings.

Yeping Yu, Qiqi Zhang, Ning Wu, Lei Xia, Jie Cao, Qiang Xia, Jie Zhao, Jianjun Zhang, Hualian Hang

Summary: Human umbilical cord mesenchymal stem/stromal cells (hUMSCs) overexpressing hepatocyte nuclear factor 4 alpha (HNF4 alpha) showed better therapeutic effects on acute liver failure (ALF) compared to hUMSCs without HNF4 alpha overexpression. The overexpression of HNF4 alpha enhanced IL-10 transcription and promoted M2 macrophage polarization through the IL-10/STAT3 pathway. This study suggests that HNF4 alpha-hUMSCs could serve as a novel therapy for ALF.
