ABSTRACT
Objective: To explore therapeutic effect of carvedilol combined valsartan on chronic heart failure (CHF), and its influence on cardiac function and level of high sensitive C reactive protein (hsCRP).Methods: A total of 78 CHF patients, who were treated in our hospital from Jul 2011 to Jul 2015, were selected.According to therapeutic method, they were divided into valsartan group (n=38, received valsartan based on routine treatment) and combined treatment group (n=40, received carvedilol based on valsartan group).Therapeutic effect, cardiac function, serum hsCRP level and quality of life (QOL) score before and after treatment were observed and compared between two groups.Results: Total effective rate of combined treatment group was significantly higher than that of valsartan group (92.50% vs.71.05%), P=0.022.Compared with before treatment, there were significant reductions in heart rate, cardiothoracic ratio (C/T), left ventricular end-diastolic dimension (LVEDd) and serum hsCRP level, and significant rise in left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), emotional index, health index and life satisfaction score in both groups after treatment except C/T of valsartan group, P<0.01 all;compared with valsartan group after treatment, there were significant reductions in heart rate [(124.39±10.07) beats/min vs.(101.18±8.72) beats/min], C/T [(0.63±0.15) vs.(0.53±0.12)], LVEDd [(43.32±4.02)mm vs.(40.38±3.76)mm] and serum hsCRP level [(32.12±3.99) pg/ml vs.(10.29±2.08) pg/ml], and significant rise in LVEF [(45.59±9.99)% vs.(59.97±10.02)%], LVFS [(24.58±5.67)% vs.(31.89±6.68)%], scores of emotional index [(70.20±10.02) scores vs.(86.58±12.28) scores], health index [(73.36±8.08) scores vs.(85.58±11.01) scores] and life satisfaction [(74.34±8.39) scores vs.(88.12±13.35) scores] in combined treatment group,P<0.05 or <0.01.Conclusion: Carvedilol combined valsartan possesses significant therapeutic effect on chronic heart failure.It can significantly reduce hsCRP level, improve cardiac function and quality of life in these patients, which is worth extending.
ABSTRACT
Objective To investigate the effects of constant magnetic field (CMF) on proliferation, apopto-sis and nitric oxide (NO) secretion of rat bone marrow-derived endothelial progenitor cells (EPCs) intervened by C-reactive protein (CRP). Methods EPCs were isolated from rat bone marrow by density gradient centrifugation and cultured on fibronectin-coated dishes. The cells were divided into five groups, i. e., control group, CRP (12 μg/ml) group, CRP plus CMF (0.1, 0. 5, 1.0 mT) groups. Samples were collected 24 hours after incubation. Cell proliferation was measured by MTT chromatometry. Apoptosis rate was detected by flow-cytometry. NO content of culture medium was measured by nitrate reductase method. Results As compared with control group, cell prolifer-ation in CRP group reduced significantly (0. 265±0. 008 vs 0. 316±0. 011, P < 0.05), NO secretion also de-creased significantly [(22.7±4.5) μmol/L vs (37.6±3.8) μmol/L, P < 0.05], cell apoptosis rate elevated sig-nificantly [(10.8±0. 8) % vs (4.2±0.5)% ,P < 0.05]. Cell proliferation in CRP plus 0. 5 mT or 1.0 mT CMF group (0. 295±0. 009,0. 302±0. 010) were much more than those in CRP group (P<0.05), NO secretion contents [(28.3±4.9) μmol/L, (29.2±5.6) μmol/L]were also much more than those in CRP group (P < 0.05) , apopto-sis rate [(7.4±0.5)% ,(6.9±0.6)%]was significantly lower than that in CRP group (P <0.05). Conclusion CMF at intensity of 0.5 mT and 1.0 mT can antagonize the effects of CR, promote proliferation of EPCs and secretion of NO and inhibit apoptosis rate of EPCs.
