[Meta-analysis of efficacy and safety of Xinmailong Injection in treatment of heart failure after acute myocardial infarction].

To systematically evaluate the clinical efficacy and safety of Xinmailong Injection in the treatment of heart failure after acute myocardial infarction. Seven Chinese and English databases, namely CNKI, VIP, Wanfang, SinoMed and PubMed, EMbase, Cochrane Library, were retrieved from the establishment of the database to March 2020. Randomized controlled trials for Xinmailong Injection in the treatment of heart failure after acute myocardial infarction were screened out.

Ln-CPs constructed from unsymmetrical tetracarboxylic acid ligand: Tunable white-light emission and highly sensitive detection of CrO, CrO, MnO in water.

A series of isostructural lanthanide coordination polymers (Ln-CPs), [Ln(Hbptc)(HO)]·HO [Ln = Er (1), Pr (2), Dy (3), Sm (4), Gd (5), Nd (6) and Tb(7); Hbptc = 2,3,3',4'-biphenyl tetracarboxylic acid] have been isolated based on an unsymmetrical tetracarboxylic acid. Single-crystal X-ray diffraction analysis reveals that all CPs featured a two dimensional (2D) layer with (6, 6, 6)-connected 6 topology. Luminescent spectra demonstrate that CPs 1-7 exhibit impressive UV-visible luminescence in the solid state at room temperature.
