Abstract:
This study was aimed to evaluate the efficacy of Tiao-Bu Fei-Shen therapies (i.e., Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, Y i-Qi Zi-Shen) on cardiac remodeling of chronic obstructive pulmonary disease (COPD) rats and its mechanisms according to the R-value comprehensive evaluation method. Based on the database of previous experiment of COPD rats, R-value comprehensive evaluation method was used to evaluate the indexes as fellows to discuss efficacy of Tiao-Bu Fei-Shen therapies on cardiac remodeling of COPD rats. ① Indicators of right ventricular morphologic indexes: right ventricular hypertrophy index (RVHI), cardiac muscle sarcomere lengths, bulk density of myocardial mitochondria (Vv), surface area (δ), membrane surface (δm), Vv, δ, δm of heart mitochondria;② Indicators of mechanisms: right ventricular endothelin-1 (ET-1), transforming growth factor-beta ( TGF-β) , vascular endothelial growth factor ( VEGF ) , basic fibroblast growth factor ( bFGF ) , matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1). The results showed that the sequence of improving effect of right ventricular remodeling at week 20 was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, aminophylline, and Y i-Qi Zi-Shen; at week 32 and the integrated week 20 and week 32, the sequence of effect was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, Y i-Qi Zi-Shen, and aminophylline. At integrated week 20 and week 32, Bu-Fei Jian-Pi had significant better intensity correcting effect than aminophylline (P< 0.01). There was no difference between week 20 and week 32. It showed that each treatment group had good long-term effect. For the mechanism of correcting effect on right ventricular remodeling, at week 20, the sequence of comprehensive effect was Bu-Fei Jian-Pi, Bu-Fei Y i-Shen, aminophylline, and Y i-Qi Zi-Shen. And Bu-Fei Jian-Pi had better effect compared with aminophylline and Y i-Qi Zi-Shen (P< 0.01); Bu-Fei Y i-Shen had better effect than Y i-Qi Zi-Shen (P< 0.05). At week 32, the sequence of effect was Y i-Qi Zi-Shen, aminophylline, Bu-Fei Jian-Pi, and Bu-Fei Y i-Shen. At the integrated week 20 and week 32, the sequence of effect was Bu-Fei Jian-Pi, and Bu-Fei Y i-Shen, Y i-Qi Zi-Shen, and aminophylline. Until week 32, the correcting effect of Tiao-Bu Fei-Shen therapies and aminophylline still maintained the same level as at week 20. It indicated that each treatment plan had good long-term effect. It was concluded that Tiao-Bu Fei-Shen therapies can improve the cardiac remodeling of COPD rats and expression of related factors in the cardiac remodeling through the R-value comprehensive evaluation method. And the effect of Bu-Fei Jian-Pi was obvious with good long-term effect.
