Inorganic-organic hybrid aluminoborates represent a subclass of porous materials, which rely on effective construction method and structure-directing agents. Herein, we prepared a series of hybrid aluminoborates through covalent decoration of unsaturated Cd complexes, whose formation take advantage of chelating amine and long-chain diamine as mixed ligands. These isolated compounds, that is, [Cd(en)(1,4-dab)][AlBO] (; its analogue with discrete complex [Cd(en)(dien)HO][AlBO] is denoted as ), [Cd(1,2-dap)(1,4-dabH)]{Al[BO(OH)](BO)} (), and [Cd(en)(1,3-dap)][AlBO] () feature open frameworks (, , and ) or a sandwich-like porous layer () that are constructed by AlO tetrahedra and [BO]/[BO(OH)] clusters.

The basic premise of syndrome essence discussion is the standardization of traditional Chinese medicine (TCM) syndrome type. However, there still exists confusion regarding the standardization of TCM syndrome differentiation treatment, and the guidelines for TCM syndrome differentiation could not really be used for guiding clinical treatment. This is mainly due to the inappropriate use of research ideas and methods.
View Article and Find Full Text PDFObjective: To evaluate the quality of reports published in recent 10 years in China about quantitative analysis of syndrome differentiation for diabetes mellitus (DM) in order to explore the methodological problems in these reports and find possible solutions.
Methods: The main medical literature databases in China were searched. Thirty-one articles were included and evaluated by the principles of clinical epidemiology.
