Network pharmacology-based exploration of molecular mechanisms underlying therapeutic effects of Jianpi Huatan Quyu recipe on chronic heart failure with spleen Qi deficiency syndrome

BACKGROUND Chronic heart failure is a complex clinical syndrome.The Chinese herbal compound preparation Jianpi Huatan Quyu recipe has been used to treat chronic heart failure;however,the underlying molecular mechanism is still not clear.AIM To identify the effective active ingredients of Jianpi Huatan Quyu recipe and explore its molecular mechanism in the treatment of chronic heart failure.METHODS The effective active ingredients of eight herbs composing Jianpi Huatan Quyu recipe were identified using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.The target genes of chronic heart failure were searched in the Genecards database.The target proteins of active ingredients were mapped to chronic heart failure target genes to obtain the common drugdisease targets,which were then used to construct a key chemical componenttarget network using Cytoscape 3.7.2 software.The protein-protein interaction network was constructed using the String database.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed through the Metascape database.Finally,our previously published relevant articles were searched to verify the results obtained via network pharmacology.RESULTS A total of 227 effective active ingredients for Jianpi Huatan Quyu recipe were identified,of which quercetin,kaempferol,7-methoxy-2-methyl isoflavone,formononetin,and isorhamnetin may be key active ingredients and involved in the therapeutic effects of TCM by acting on STAT3,MAPK3,AKT1,JUN,MAPK1,TP53,TNF,HSP90AA1,p65,MAPK8,MAPK14,IL6,EGFR,EDN1,FOS,and other proteins.The pathways identified by KEGG enrichment analysis include pathways in cancer,IL-17 signaling pathway,PI3K-Akt signaling pathway,HIF-1 signaling pathway,calcium signaling pathway,cAMP signaling pathway,NF-kappaB signaling pathway,AMPK signaling pathway,etc.Previous studies on Jianpi Huatan Quyu recipe suggested that this Chinese compound preparation can regulate the TNF-α,IL-6,MAPK,cAMP,and AMPK pathways to affect the mitochondrial structure of myocardial cells,oxidative stress,and energy metabolism,thus achieving the therapeutic effects on chronic heart failure.CONCLUSION The Chinese medicine compound preparation Jianpi Huatan Quyu recipe exerts therapeutic effects on chronic heart failure possibly by influencing the mitochondrial structure of cardiomyocytes,oxidative stress,energy metabolism,and other processes.Future studies are warranted to investigate the role of the IL-17 signaling pathway,PI3K-Akt signaling pathway,HIF-1 signaling pathway,and other pathways in mediating the therapeutic effects of Jianpi Huatan Quyu recipe on chronic heart failure.

Echocardiographic Evaluation of Qiangxin Decoction Combined with Cardiac Resynchronization Therapy for Patients with Chronic Heart Failure

OBJECTIVE: To explore the echocardiographic evaluation of patients with chronic heart failure (CHF) after Qiangxin Decoction combined with cardiac resynchronization therapy. METHODS: A total of 140 CHF patients admitted to our hospital were randomly divided into combined group (Qiangxin Decoction and cardiac resynchronization, n = 70) and routine group (cardiac resynchronization, n = 70), and they were treated for 2 courses (16 weeks), with 8 weeks as a course. The improvement of heart function classification (HYHA) was observed before and after treatment, and the therapeutic effects were evaluated according to the improvement of heart function classification (markedly effective, effective, invalid, and worsening). The traditional Chinese medicine (TCM) diagnostic criteria was the main symptoms (0 to 6 points), secondary symptoms (0 to 3 points), tongue picture (0 to 1 point) and pulse condition (0 to 1 point), and the higher the score was, the more obvious the symptoms were. The left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF) and cardiac output (CO) were observed and recorded according to the heart color ultrasound before and after treatment. And the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to evaluate the life quality before and after treatment, and the highest score of the scale was 105 points. The higher the score was, the obvious the symptoms were, and the worse the life quality was. And the adverse reactions were recorded in the 2 groups. RESULTS: After the treatment, the total effective rate in the routine group was significantly lower than that in the combined group (75.71% vs . 94.30%), and there was statistically significant difference (P < 0.05). After the treatment, the TCM syndrome score in the routine group was higher than that in the combined group ((14.37±3.59) points vs.(10.53±3.11) points), and there was statistically significant difference (P < 0.05). After the treatment, the levels of LVEDD and LVESD in the routine group were higher than those in the combined group, and there were statistically significant differences (P < 0.05). The levels of LVEF and CO in the routine group were lower than those in the combined group, and there were statistically significant differences (P < 0.05). After the treatment, the score of MLHFQ scale in the routine group was higher than that in the combined group ((57.38±8.53) points vs.(46.39±7.14) points), and there was statistically significant difference (P < 0.05). CONCLUSION: Qiangxin Decoction combined with cardiac resynchronization therapy has good echocardiographic evaluation in patients with chronic heart failure.

Prognostic impact of atrial fibrillation on clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease

Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

High Density Lipoprotein Phospholipids as a Marker of Coronary Heart Disease of Shen-Yang Deficiency Syndrome

Objective: To seek a new biochemical index for diagnosis of coronary heart disease (CHD) of shen-Yang deficiency syndrom (CHD-SYD). Methods: Sixty-one patients with CHD were divided into 3 groups according to their TCM Syndrome type, 10 patients in the group without Xin-Qi deficiency (Group A), 25 in the group with Xin-Qi deficiency but without Shen-Yang deficiency (Group B) and 26 in the group both with Xin-Qi deficiency and Shen-Yang deficiency (Group C). Levels of 17-hydroxy-corticoste-roid in urine (urinary 17-OHCS) per 24 hrs, and serum level of high density lipoprotein cholesterol (HDL-C) and high density lipoprotein phospholipid (HDL-PL) in them were determined in synchrostep and compared with those in the control group of 23 healthy aged persons, urinary 17-OHCS per 24 hrs was taken as the diagnostic standard to screen a new index for diagnosis of Shen-Yang deficiency Syndrome, and preliminary appraisal to the index was made. Results: Serum HDL-PL in the CHD-SYD patients( Group C) was 616+157 mg/L, which was obviously lower than that in the patients of Group A and B. With low HDL-PL(<650 mg/L) used as the index to diagnose CHD-SYD, the sensitivity was 73%, the specificity 86% and the accuracy 80%. Conclusion: HDL-PL <650 mg/L could be adopted as an index for CHD-SYD diagnosis, which is simple and practical.

Role of imaging in the evaluation of renal dysfunction in heart failure patients

Heart failure and kidney disease share common pathophysiological pathways which can lead to mutual dysfunction,known as cardiorenal syndrome.In heart failure patients,renal impairment is related to hemodynamic and nonhemodynamic factors.Both decreased renal blood flow and renal venous congestion due to heart failure could lead to impaired renal function.Kidney disease and worsening renal function are independently associated with poor prognosis in heart failure patients,both in acute and chronic clinical settings.The aim of this review is to assess the role of renal imaging modalities in the evaluation and management of heart failure patients.Renal imaging techniques could complete laboratory data,as estimated glomerular filtration rate,exploring different pathophysiological factors involved in kidney disease and adding valuable information about renal structure and function.In particular,Doppler examination of arterial and venous hemodynamics is a feasible and non invasive technique,which has proven to be a reliable method for prognostic stratification in patients with cardiorenal syndrome.The renal resistance index,a measure related to renal hemodynamics,can be calculated from the Doppler evaluation of arterial flow.Moreover,the analysis of Doppler venous flow patterns can integrate information from the arterial study and evaluate renal congestion.Other imaging modalities are promising,but still confined to research purposes.

Effect of Jiawei Shenfu decoction on tumor necrosis factor-alpha and nuclear factor-kappa B in patients who have chronic heart failure with syndromes of deficiency of heart Yang

OBJECTIVE:To examine the clinical efficacy of Jiawei Shenfu decoction on tumor necrosis factor-alpha (TNF-cα) and nuclear factor-kappa B (NF-KB) levels in patients who have chronic heart failure with syndromes of deficiency of heart Yang.METHODS:A total of 63 patients with syndromes of deficiency of heart Yang (chronic heart failure)were enrolled.Patients were randomly divided into the control group and Jiawei Shenfu group.All patients received standard medications for treatment of chronic heart failure.Patients in the Jiawei Shenfu group were additionally provided Jiawei Shenfu decoction one dose daily.Treatments continued for 4 consecutive weeks.The primary endpoint was the change in plasma B-type natriuretic peptide (BNP),NF-KB,and TNF-cα levels during 4 weeks of treatment.RESULTS:At the 4-week follow-up,a significant reduction in BNP levels compared with baseline was observed in both groups,but the Jiawei Shenfu decoction group showed a significantly greater reduction than did the control group.The Jiawei Shenfu group also showed superior performance regarding the Minnesota Living with Heart Failure Questionnaire score,the Chinese medicine syndrome score,heart rate,left ventricular ejection fraction,and 6-min walking distance compared with the control group.The degree of changes in NF-KB and TNF-α levels in the Jiawei Shenfu group was more significant than that in the control group.CONCLUSION:Routine medicine combined with Jiawei Shenfu decoction for patients with heart Yang deficiency syndrome in chronic heart failure can improve the left ventricular ejection fraction and cardiac function,and reduce BNP levels.The mechanism may be related to inhibition of pro-inflammatory cytokines and the NF-KB-induced kinase pathway,leading to amelioration of the inflammatory response.

Performance measures for management of chronic heart failure patients with acute coronary syndrome in China： results from the Bridging the Gap on Coronary Heart Disease Secondary Prevention in China （BRIG） Project

Background Chronic heart failure （CHF） is a severe clinical syndrome associated with high morbidity and mortality, and with high health care expenditures. No nationwide data are currently available regarding the quality of clinical management of CHF patients in China. The aim of this study was to assess the quality of care of CHF inpatients in China. Methods The American College of Cardiology/American Heart Association Clinical Performance Measures for Adults with Chronic Heart Failure （Inpatient Measurement Set） with slight modifications was used to measure the performance status in 612 CHF patients with acute coronary syndrome （ACS） from 65 hospitals across all regions of China. Results The implementation rates of guideline recommended strategies for CHF management were low. Only 57.5% of the CHF patients received complete discharge instructions, 53.6% of the patients received evaluation of left ventricular systolic function, 62.8% received an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker at discharge, and 52.7% received a p-blocker at discharge, 56.3% of the smokers received smoking cessation counseling. The rate of warfarin utilization was only 9.7% in CHF patients with atrial fibrillation. Most patients （81.4%） did not receive all the first four treatments. There were marked differences in the quality of CHF management among patients with different characteristics. Conclusions Performance measures provide a standardized method of assessing quality of care, and can thus highlight problems in disease management in clinical practice. The quality of care for CHF patients with ACS in China needs to be improved.

Clinical study on long-snake moxibustion plus Western medicine in treating chronic heart failure due to heart-kidney yang deficiency

Objective To observe the clinical efficacy of long-snake moxibustion plus Western medicine for chronic heart failure due to heart-kidney yang deficiency.Methods A total of 80 patients were randomized into a control group and an observation group,with 40 cases in each group.The control group was treated with routine Western medicine,and the observation group was treated with long-snake moxibustion therapy on the basis of routine Western medicine.Left ventricular ejection fraction(LVEF),stroke volume(SV)and left ventricular end-diastolic diameter(LVEDd)were measured before and after treatment,and the heart function was assessed.The serum brain natriuretic peptide(BNP)level was measured,the 6 min walking distance was recorded,and the Minnesota living with heart failure questionnaire(MLHFQ)was assessed and scored.The serum galectin-3(Gal-3)and soluble growth stimulation expressed gene 2(sST2)protein levels were measured.Clinical efficacy was evaluated after treatment.Results The total effective rate of the observation group was higher than that of the control group,and the difference between the two groups was statistically significant(P<0.05).After treatment,LVEF and LVEDd in both groups were significantly improved(all P<0.05),and LVEF,SV and LVEDd in the observation group were superior to those in the control group(all P<0.05).The heart function classification in both groups were improved after treatment(both P<0.05),and the heart function classification in the observation group was superior to that in the control group(P<0.05).The serum BNP level in both groups decreased(both P<0.05),and the serum BNP level in the observation group was lower than that in the control group(P<0.05).The 6 min walking distance and MLHFQ scores in both groups were improved(all P<0.05),and the 6 min walking distance and MLHFQ score in the observation group were superior to those in the control group(both P<0.05).The serum Gal-3 and sST2 levels in the observation group decreased significantly(both P<0.05),and all lower than those in the control group(both P<0.05).Conclusion Long-snake moxibustion plus Western medicine has significant efficacy in treating chronic heart failure due to heart-kidney yang deficiency;it can improve heart function,reduce the serum BNP level,and improve the exercise endurance and quality of life in the patients.This may be related to the down-regulation of serum Gal-3 and sST2 levels.

Autonomic neurocardiogenic syndrome is stonewalled by the universal definition of myocardial infarction

Myocardial infarction(MI)is defined as myocardial cell death due to prolonged myocardial ischemia.Clinically,troponin rise and/or fall have become the“defining feature of MI”according to the universal definition of MI(UD-MI).Takotsubo syndrome(TS)and TS-related disease conditions also cause troponin elevation with typical rise and/or fall pattern but through a mechanism other than coronary ischemia.By strict application of the clinical diagnostic criteria for type-1 MI,type-2 MI,type-3 MI,and MI with non-obstructive coronary arteries according to the UD-MI including the fourth one published recently,TS and most of the 26 other causes of troponin elevation mentioned in the fourth UD-MI may erroneously be classified as MI.The existing evidence argues for the case that TS by itself is not a MI.Hyper-activation of the autonomic-sympathetic nervous system including local cardiac sympathetic hyper-activation and disruption with nor-epinephrine churn and spillover is the most probable cause of TS.This autonomic neuro-cardiogenic(ANCA)mechanism results in myocardial“cramp”(stunning),the severity and duration of which depend on the degree of the sympathetic-hyperactivation and nor-epinephrine spillover.The myocardial cramp may squeeze the cytosolic free troponin pools causing mild to moderate troponin elevation in TS and TS-related disease conditions.This ANCA syndrome,which has hitherto been enveloped by the UD-MI over more than one decade,may occur in acute,recurrent,and chronic forms.In this critical review,the controversies of UD-MI,evidence for ANCA syndrome,and a hypothetical mechanism for the troponin elevation in ANCA syndrome are provided.

基于“动则生阳”理论探讨鸢尾素与慢性心力衰竭心阳虚证本质的联系

慢性心力衰竭(chronic heart failure, CHF)是各种原因导致的心脏疾病终末阶段,心阳不足是导致CHF恶化的关键病因。鸢尾素是一种肌动蛋白糖基化蛋白激素,是纤维连接蛋白Ⅲ型结构域5(fibronectin typeⅢdomain containing 5, FNDC5)的多肽切割产物,同时也是一种依赖于过氧化物酶体增殖物激活受体γ共激活物-1α(peroxisome proliferator-activated receptor γ coactivator-1α, PGC-1α)的肌细胞因子。在肌肉运动时,PGC-1α通过刺激FNDC5表达,增加鸢尾素释放并介导运动相关的效应。在这一过程中产生的鸢尾素可以增加线粒体产能和脂肪褐变产热,促进葡萄糖代谢和脂肪酸氧化。“动则生阳”理论源于《易经》,其指出“动”是化生阴阳万物的起源。对于CHF心阳虚证患者,运动可振奋其心阳,促进人体气血通畅,改善CHF症状,促进疾病向愈。“动则生阳”的本质可能是运动改善了CHF心阳虚证患者的“气虚”和“寒象”状态,可能与机体运动时产生的鸢尾素调控了能量代谢及线粒体产能有关。因此,推测缺乏鸢尾素可能是CHF心阳虚证的生物学内涵。
