Abstract

The invention discloses new application of sodium houttuyfonate in pharmacy, in particular to the application of the sodium houttuyfonate in preparing medicaments for preventing and treating myocardial hypertrophy and / or ventricular hypertrophy. The application is to prepare an in-vitro myocardial cell hypertrophyby adopting three methods of preparing an in-vivo animal model of myocardial hypertrophy and ventricular hypertrophy, culturing a myocardial cell in vitro and inducing epinephrine by isoproterenol, L-thyroxine and abdominal aorta banding. Experiment results prove that the sodium houttuyfonate can reduce the increase of left cardiac index and global cardiac index of a model animal, inhibit hypertrophy of an in-vitro myocardial cell, reduce the cAMP concentration of plasma, the content of Ang II and ET-1 of a myocardial tissue and the content of TNF-alpha and ALD of serum, and can reduce blood pressure and decrease heart rate. Experiment results suggest that the sodium houttuyfonate has the functions of resisting myocardial hypertrophy and ventricular hypertrophy, and the mechanism of the sodium houttuyfonate can be related to the inhibition of sympathetic activity, blockage of system activity of feritin-hypertensin-aldosterone, and effect of endocrine factors.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to the use of houttuyfonate sodium, an active ingredient of traditional Chinese medicine, in the preparation of medicines for preventing and treating myocardial hypertrophy and / or ventricular hypertrophy. Background technique [0002] Chronic cardiac insufficiency, also known as congestive heart failure (CHF), is a clinical syndrome in which the pumping function of the heart is reduced due to various etiologies and cannot discharge enough blood to meet the metabolic needs of tissues and organs throughout the body. The fatality rate is high. [0003] In the past, the clinical treatment of CHF focused on the use of cardiac glycosides with positive inotropic effects and diuretics. A large number of clinical data show that although all drugs that enhance myocardial contractility and improve hemodynamics can achieve a certain effect of improving symptoms in the short term, they cannot prevent ventr...
