[Qangxin Granule Intervened Chronic Heart Failure Rats with Xin-qi Deficiency Complicated Blood Stasis and Edema Syndrome: an Experimental Study].

AbstractOBJECTIVE:
To study and evaluate the curative effect and mechanism of Qiangxin Granule (QXG) in intervening chronic heart failure (CHF) rats with Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BS-ES).
METHODS:
Totally 72 SD rats of clean grade were randomly divided to the normal control group (n =10) and the model group (n = 62). The XQD-BS-ES rat model was established by adriamycin plus propylthiouracil method. Survived modeled rats were then randomly divided to 5 groups i.e., the model group (n = 11, administered with normal saline by gastrogavage), the Western medicine (WM) group (n =11 , administered with perindopril and hydrochlorothiazide by gastrogavage), the low dose QXG (QXG(L)) group (n = 11, administered with 9.26 g/kg QXG by gastrogavage), the middle dose QXG (QXG(M)) group (n = 11, administered with 18.52 g/kg QXG by gastrogavage), the high dose QXG (QXG(H)) group (n = 11, administered with 37.04 g/kg QXG by gastrogavage). After 4 weeks of treatment, left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), tri-iodothyronine (T3), tetra-iodothyronine (T4), thyroid stimulating hormone (TSH), as well as heart, lung, liver weight index and their pathological sections, and high sensitivity C-reactive protein (HS-CRP), angiotensin II (Ang II), carbohydrate antigen 125 (CA125) were detected and compared.
RESULTS:
Compared with the normal control group, LVEF, LVFS, BNP, HR, RR, urine output, ear temperature, EST, T3, T4, TSH, HS-CRP, Ang II, and CA125 changed significantly in the model group (P < 0.01). Compared with the model group after treatment, LVEF, LVFS, BNP, urine output, EST, T4, heart and liver weight index, HS-CRP, Ang II, CA125 were significantly improved in each QXG group (P < 0.05, P < 0.01). Moreover, TSH was improved in the QXGL and QXG(M) groups (P < 0.05); ear temperature and T3 in the QXG(M) were also improved (P < 0.05); the lung weight index decreased in the QXG(M) and QXG(H) groups (P < 0.01). Compared with the WM group, T4 and CA125 were obviously improved in all QXG groups (P < 0.01); BNP and ear temperature were obviously improved in QXG(L) and QXG(M) groups (P < 0.05, P < 0.01); LVEF, LVFS and TSH were obviously improved in the QXG(M) group (P < 0.05, P < 0.01). And as far as each treatment group, LVEF, LVFS, urine output increased significantly after treatment (P < 0.01); EST obviously increased in QXG(M) and QXG(H) groups (P < 0.01); ear temperature increased in all QXG groups (P < 0.05, P < 0.01). Moreover, compared with the model group, pathological changes of heart, lung, and liver were improved to some degree in each treatment group, especially in the QXG(M) group.
CONCLUSIONS:
Good curative effect was shown in each QXG group. QXG could improve LVEF, LVFS and BNP of CHF rats of XQD-BS-ES, as well as T3, T4, TSH, EST, urine output, and ear temperature. Moreover, QXG showed superiority than WM group in this respect.
