Abstract: Three-dimensional (3D) hierarchical morphologies widely exist in natural and biomimetic materials, which impart preferential functions including liquid and mass transport, energy conversion, and signal transmission for various applications. While notable progress has been made in the design and manufacturing of various hierarchical materials, the state-of-the-art approaches suffer from limited materials selection, high costs, as well as low processing throughput. Herein, by harnessing the configurable elastic crack engineering-controlled formation and configuration of cracks in elastic materials, an effect normally avoided in various industrial processes, the present invention provides a facile and powerful technique to enable the faithful transfer of arbitrary hierarchical structures with broad material compatibility and structural and functional integrity.

Abstract: A method of preparing medicaments for treating dilated cardiomyopathy includes the step of applying ginsenoside Rb1. Long-term treatment of ginsenoside Rb1 can reduce the mortality rate, improve the cardiac function, reduce the dilation of the left ventricular, reduce the hypertrophy of myocytes and the proliferation of collagen, reduce the uneven thickness of myocytes, mitochondrial swelling, break of crista, sarcoplasmic reticulum expansion and destruction of intercalated disc connection, increase the expression of connexin Cx40, E-cadherin and P-cadherin, fibroblast growth factor FGF2, FGF7, FGF8, FGF10, and reduce the expression of integrin Itga8 and Itgbp.
