[0046] 1. Experimental materials

[0047] 1.1 Animal handling

[0048] 180-220g male SD rats were purchased from the Experimental Animal Center of Ningxia Medical University, animal production license number: NCXK (Ning) 2015-0005. Feeding conditions include standard feed, tap water, room temperature maintained at (21±2)°C, humidity 50-60%, and daily light and dark times of 12 hours each. Before the experiment, the animals were placed in the experimental environment for 7 days to adapt.

Abstract

The invention discloses application of aloperine (ALO) to preparation of a medicine for preventing and curing pulmonary arterial hypertension. A rat pulmonary hypertension model is established to explore the protection effect and mechanism of aloperine on rat pulmonary hypertension. The experiment shows that after the pulmonary hypertension model is established, the aloperine can remarkably improve the hemodynamic parameter, the right ventricular hypertrophy index, the lung index, and the echocardiographic parameter, the pathological injury of pulmonary arterioles is improved, the antioxidant ability of a lung tissue is improved, and the malondialdehyde content and the level of nicotinamide adenine dinucleotide phosphate oxidase (NOX)-2 and NOX-4 in the lung tissue are reduced. The aloperine has the effects of inhibiting the development of pulmonary arterial hypertension, oxidative stress and overexpression of NOX-2 and NOX-4.

Description

technical field [0001] The present invention relates to the application of aloperine, in particular to the application of aloperine in the preparation of drugs for prevention and treatment of pulmonary arterial hypertension. Background technique [0002] Pulmonary hypertension is a group of clinical syndromes characterized by a progressive increase in pulmonary artery pressure and pulmonary vascular resistance, resulting in increased right ventricular afterload and decreased pulmonary blood flow. Continuously increased pulmonary vascular resistance can lead to right ventricular failure and eventually cause death. Studies have found that the pathogenesis of pulmonary hypertension includes pulmonary vascular endothelial dysfunction, pulmonary inflammatory response, pulmonary artery vasoconstriction, pulmonary vascular wall remodeling, and imbalance between smooth muscle cell proliferation and apoptosis. As far as the current drugs for the treatment of pulmonary hypertension a...
