Molecular Mechanism of Yangshen Maidong Decoction in the Treatment of Chronic Heart Failure based on Network Pharmacology, Molecular Docking, and Molecular Dynamics Simulations.

Chronic heart failure (CHF) is a complex multifactorial clinical syndrome leading to abnormal cardiac structure and function. The severe form of this ailment is characterized by high disability, high mortality, and morbidity. Worldwide, 2-17% of patients die at first admission, of which 17-45% die within 1 year of admission and >50% within 5 years.

[Experimental study of implantable engineered liver tissue using type I collagen gel as scaffold].

Objective: To construct implantable engineered liver tissue (ELT) using type I collagen gel as scaffold.

Methods: Type I collagen was obtained from the tail of a rat. Hepatocytes were collected from a Sprague-Dawley rat, mixed with liquid type I collagen and Dulbecco's modified Eagle's medium to create hepatocyte/collagen gel construct.
