Research progress of histone acetylation in prevention and treatment of heart failure and new ideas based on traditional Chinese medicine / 中国中药杂志

Chronic heart failure(CHF) has become a worldwide public health problem due to its high morbidity and mortality, which seriously endangers people's lifespan and quality of life. In recent years, the treatment strategy of CHF has shifted its emphasis on short-term improvement and transformation of hemodynamics to long-term repair as well as improvement of the biological properties of heart failure. At present, with the continuous deepening of medical research, it has been found that histone acetylation is closely related to the occurrence and development of CHF. Traditional Chinese medicine, via regulating histone acetylation, delays ventricular remodeling, improves energy metabolism, inhibits fibrosis and cardiomyocyte hypertrophy, and intervenes in the development process of heart failure, thus reducing the mortality and the readmission rate and ultimately improving long-term prognosis. Therefore, this study reviewed the mechanism of histone acetylation in the treatment of heart failure as well as its prevention and treatment with traditional Chinese medicine, to provide reference for clinical treatment of CHF.

Correlations Between Severity of Heart Failure Related to Coronary Heart Disease of Qi Deficiency and Blood Stasis Syndrome and Biological Indexes / 中国实验方剂学杂志

Objective:To explore the correlations of the severity of heart failure related to coronary heart disease arising from Qi deficiency and blood stasis with cardiac function indexes， energy metabolism indexes， coagulation function indexes， and inflammatory factors， in order to provide a scientific basis for further research on the biological foundation of this disease. Method:Two hundred patients with heart failure related to coronary heart disease of Qi deficiency and blood stasis syndrome were collected and then classified into mild， moderate and severe groups according to their scores of Qi deficiency and blood stasis syndrome. Meanwhile， 40 healthy persons confirmed by physical examination during the same period were included into the control group. Such biological indexes as cardiac function indexes， energy metabolism indexes， coagulation function indexes， and inflammatory factors were determined in patients of each group for comparison. Then the Spearman rank correlation analysis was conducted to figure out the correlations between differential indexes and the severity of Qi deficiency and blood stasis syndrome， followed by the determination of risk factors for the severity of Qi deficiency and blood stasis syndrome by ordered logistic regression analysis. Result:The cardiac function indexes， energy metabolism indexes， coagulation function indexes， and inflammatory factors in patients with heart failure related to coronary heart disease arising from Qi deficiency and blood stasis varied significantly. There were significant statistical differences in the levels of N-terminal pro-B-type natriuretic peptide （NT-ProBNP）， 6-minute walk test （6MWT）， heart-type fatty acid-binging protein （H-FABP）， prothrombin time （PT）， activated partial thromboplastin time （APTT）， tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>）， and nitric oxide （NO） among the mild， moderate， and severe groups （<italic>P</italic><0.05）. The severity of Qi deficiency and blood stasis syndrome was positively correlated with NT-ProBNP （<italic>r</italic>=0.144）， PT （<italic>r</italic>=0.173）， and APTT （<italic>r</italic>=0.144）， but negatively with 6MWT （<italic>r</italic>=-0.287）. The 6MWT［odds ratio（OR）=0.995， 95% confidence interval（CI） 0.991-0.998），<italic>P</italic><0.01］ and APTT（OR=1.088，95%CI 1.021-1.157，<italic>P</italic><0.01） were independent risk factors affecting the severity of heart failure related to coronary heart disease arising from Qi deficiency and blood stasis. Conclusion:The severity of heart failure related to coronary heart disease of Qi deficiency and blood stasis syndrome is closely related to NT-ProBNP， 6MWT， H-FABP， PT， APTT， TNF-<italic>α</italic>， and NO. Moreover， 6MWT and APTT can be used as independent risk factors to evaluate the severity of patients with heart failure related to coronary heart disease due to Qi deficiency and blood stasis.

Key points of post-marketing evaluation of classic traditional Chinese medicine prescriptions based on combination of disease and syndrome / 中国中药杂志

Classic prescriptions, hospital preparations and famous traditional Chinese medicine(TCM) experience prescriptions are the main sources of new drug development and innovation. The multi-components and multi-targets treatment characteristics of TCM are advantages, but at the same time, broad indications, unclear clinical positioning and lack of evidence-based evidence support are the key problems affecting the play of TCM efficacy and restricting its promotion and application. The hot in recent research was to how to break through the bottleneck, precise clinical positioning, highlight the advantages of the classic TCM prescriptions, and complete the transformation from clinical practice, clinical research to clinical evidence, but at the same time, it is also the difficulty. The clinical research model of the combination of disease and syndrome can fully reflect the ancient medical case evidence of classic TCM prescriptions, the historical experience of human used and the characteristics of syndrome differentiation and treatment, and highlight the advantages of Chinese medicine. At the same time, under the modern disease classification system and research mode, is conducive to established the standardized clinical evidence report and evaluation system, is conducive to promote the integration of clinical research evidence, and avoids excessive attenuation of information. Based on the previous work of our team, the intention of this study was to make a comment about the key points of the post-marketing evaluation of the classic TCM prescriptions under the combination of disease and syndrome and includes key points:(1)With the syndrome as the carrier, connected with the classical prescription and clinical diseases, focused on the clinical positioning on macroscopically.(2)The combination of syndrome visualization, standardization and pharmacological molecular basis, focus on clinical precise positioning in microscopic.(3)Innovating therapeutic effect evaluation methods, reflecting the curative effect characteristics based on syndrome differentiation.(4)The combination of "randomized controlled evidence-based studies" and "real world evidence-based evaluation", focusing on clinical advantages, fully evidence-based evidence.(5)Make full use of clinical registration studies and pay attention to safety.
