ACE2 overexpression ameliorates left ventricular remodeling and dysfunction in a rat model of myocardial infarction.

The purpose of this study was to test the hypothesis that overexpression of angiotensin-converting enzyme 2 (ACE2) may favorably affect left ventricular (LV) remodeling and function after myocardial infarction (MI). The left anterior descending coronary artery was ligated to produce anterior MI in 100 Wistar-Kyoto rats that were randomly divided into Ad-ACE2, Ad-ACE2+A779, Ad-EGFP, model, and sham groups. Two weeks later, rats in the Ad-ACE2 and Ad-EGFP groups received direct intramyocardial injection of Ad-ACE2 and Ad-EGFP, respectively.

Effect of traditional Chinese medicine Shu-Mai-Tang on attenuating TNFalpha-induced myocardial fibrosis in myocardial ischemia rats.

Shu-Mai-Tang (SMT) is a traditional Chinese medicine for treatment of ischemic heart disease. The effect of SMT on inflammation-induced myocardial fibrosis, left ventricular (LV) remodeling, and the potential mechanism in myocardial ischemia (MI) rats were investigated. Rats with ligated left anterior descending coronary artery (MI model) were randomly divided into three groups (SMTL, SMTH, and MIR).

[Experimental study on effect of Shumai capsule in promoting angiogenesis in rats with myocardial ischemia].

Objective: To study the effect of Shumai Capsule (SMC) on angiogenesis and expression of relevant growth factor in rats with myocardial ischemia (MI).

Methods: Model rats of MI were duplicated and treated with SMC (SMC group), bFGF + calparine (positive control group) and normal saline (model group) respectively. Besides, a sham-operative group was set up and treated with normal saline.

Improvement of vascular remodeling in spontaneous hypertensive rats with traditional Chinese medicine.

Qin-Dan-Jiang-Ya-Tang (QDJYT) is a traditional Chinese herbal medicine for the treatment of hypertension. The effect of QDJYT on blood pressure (BP) and vascular remodeling in hypertension was investigated in the model of spontaneous hypertensive rats (SHR). Sixteen SHRs were divided into two groups: the SHR group and the SHR+ QDJYT group.

Effect of traditional Chinese medicine Qin-Dan-Jiang-Ya-Tang on remodeled vascular phenotype and osteopontin in spontaneous hypertensive rats.

Qin-Dan-Jiang-Ya-Tang (QDJYT) is a traditional Chinese herbal medicine for the treatment of hypertension. The effect of QDJYT on blood pressure and on vascular remodeling in hypertension was investigated in the model of spontaneous hypertensive rats (SHR). Sixteen SHRs were divided into two groups, the SHR group and the SHR+QDJYT group.
