ABSTRACT
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.

This study reviewed the current status of the use of outcome indicators in randomized controlled trial(RCT) on traditional Chinese medicine(TCM) treatment of microvascular angina(MVA) and analyzed the existing problems and possible solutions, aiming to provide a basis for the design of high-quality RCT and the establishment of core outcome sets for MVA. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, Web of Science, and 2 clinical trial registries were searched for the RCT on TCM treatment of MVA according to pre-defined criteria. The Cochrane's risk of bias assessment tool was used to evaluate the methodological quality of the included RCT and the use of outcome indicators was summarized. A total of 69 RCTs were included, from which 100 outcome indicators were extracted, with the frequency of 430. The extracted outcome indicators belonged to 8 domains: response rate, symptoms and signs, physical and chemical examinations, TCM efficacy, safety, quality of life, economic evaluation, and long-term prognosis. The indicators of physical and chemical examinations were the most(70 indicators with the frequency of 211), followed by those of response rate(7 indicators with the frequency of 73) and symptoms and signs(7 indicators with the frequency of 54). The outcome indicators with higher frequency were adverse reactions, angina attack frequency, clinical efficacy, endothelin-1, total duration of treadmill exercise, and hypersensitive C-reactive protein. The RCT on TCM treatment of MVA had the following problems: irregular reporting of adverse reactions, diverse indicators with low frequency, lack of attention to the application of endpoint indicators, insufficient use of TCM differentiation and efficacy indicators, non-standard evaluation criteria and failure to reflect the basic characteristics of TCM. A unified MVA syndrome differentiation standard should be established, on the basis of which an MVA treatment efficacy evaluation system and core outcome indicator set that highlights the characteristics of TCM with patient-reported outcomes as the starting point should be established to improve the clinical research and research value.

Accurate assessment of the risks associated with traditional Chinese medicine(TCM), such as the potential to induce serious cardiovascular adverse reactions including cardiac arrhythmias, is crucial. This article introduced the pharmacological evaluation strategies for cardiac safety and the progress in cardiac organ research, with a focus on discussing the application prospects of human induced pluripotent stem cells(hiPSCs) and organoids in assessing the risks of TCM-induced cardiac arrhythmias. Compared with traditional animal models, hiPSCs and organoid models provide better reference and predictive capabilities, allowing for more accurate simulation of human cardiac responses. Researchers have successfully generated various cardiac tissue models that mimic the structure and function of the heart to evaluate the effects of TCM on the heart. The hiPSCs model, by reprogramming adult cells into pluripotent stem cells and differentiating them into cardiac cells, enables the generation of personalized cardiac tissue, which better reflects individual differences and drug responses. This provides guidance for the assessment of TCM cardiac toxicity risks. By combining organoid model with cardiac safety pharmacology strategies such as electrocardiogram monitoring and ion channel function assessment, the impact of TCM on the heart can be comprehensively evaluated. In addition, the application of the Comprehensive in Vitro Proarrhythmia Assay(CiPA) approach improves the accuracy of evaluation. Applying the CiPA approach to TCM research reveals potential risks and provides a scientific basis for the clinical application and industrial development of TCM. In conclusion, organoid model and cardiac safety pharmacology evaluation strategies provide important tools for assessing the cardiac toxicity risks of TCM. The combination of hiPSCs model, comprehensive assessment methods, and the CiPA strategy enables an accurate assessment of the risks of TCM-induced cardiac arrhythmias, thus providing a scientific basis for the safe use and international recognition of TCM in clinical practice. This contributes to ensuring the safety and efficacy of TCM and promoting its clinical application and global acceptance.

This study aims to systematically review the efficacy and safety of different traditional Chinese medicine injections combined with conventional treatment for patients with post-acute myocardial infarction heart failure. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library with the time interval from inception to May 13, 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network Meta-analysis was then performed in RevMan 5.3 and Stata 15.1. A total of 68 RCTs involving 11 traditional Chinese medicine injections and 5 995 patients were included. The results were explained based on the surface under the cumulative ranking curve(SUCRA).(1) In terms of reducing major adverse cardiovascular event(MACE), the therapies followed the trend of Xinmailong Injection+conventional treatment(83.8%) > Yiqi Fumai Injection+conventional treatment(57.1%) > Xuebijing Injection+conventional treatment(56.6%) > Shenmai Injection+conventional treatment(53.1%) > Shenfu Injection+conventional treatment(45.3%) > conventional treatment(4.0%).(2) In terms of increasing left ventricular ejection fraction(LVEF), the therapies followed the trend of Yiqi Fumai Injection+conventional treatment(84.0%) > Shenmai Injection+conventional treatment(69.6%) > Shenfu Injection+conventional treatment(62.7%) > Xinmailong Injection+conventional treatment(61.6%) > Shuxuening Injection+conventional treatment(54.8%) > Shenqi Fuzheng Injection+conventional treatment(46.7%) > Shengmai Injection+conventional treatment(45.9%) > Breviscapine Injection+conventional treatment(39.9%) > Danhong Injection+conventional treatment(38.8%) > Huangqi Injection+conventional treatment(38.7%) > conventional treatment(7.3%).(3) In terms of reducing B-type natriuretic peptide(BNP), the therapies followed the trend of Xinmailong Injection+conventional treatment(98.6%) > Shenmai Injection+conventional treatment(57.7%) > Shenfu Injection+conventional treatment(52.5%) > Shengmai Injection+conventional treatment(30.1%) > conventional treatment(11.0%).(4) In terms of reducing cardiac troponin Ⅰ(cTnⅠ), the therapies followed the trend of Shenmai Injection+conventional treatment(92.3%) > Yiqi Fumai Injection+conventional treatment(61.5%) > Shenfu Injection+conventional treatment(51.2%) > Shengmai Injection+conventional treatment(48.1%) > Xinmailong Injection+conventional treatment(26.6%) > conventional treatment(20.3%).(5) In terms of reducing high-sensitivity C-reactive protein(hs-CRP), the therapies followed the trend of Shenmai Injection+conventional treatment(79.9%) > Xinmailong Injection+conventional treatment(68.1%) > Shenfu Injection+conventional treatment(63.1%) > Xuebijing Injection+conventional treatment(56.7%) > Shengmai Injection+conventional treatment(51.1%) > Shenqi Fuzheng Injection+conventional treatment(42.8%) > Huangqi Injection+conventional treatment(34.7%) > conventional treatment(3.5%).(6) A total of 22 RCTs reported the occurrence of adverse reactions, mainly involving the damage of the circulatory system, digestive system, and coagulation function. The current evidence suggested that Xinmailong Injection+conventional treatment may have the best therapeutic effect in reducing MACE and BNP; Yiqi Fumai Injection+conventional treatment may be the best in increasing LVEF; Shenmai Injection+conventional treatment may be the best in reducing cTnI and hs-CRP. The safety needs further quantitative research and analysis. However, more high-quality RCT is required to validate the above conclusions due to limitations in the quality and quantity of the included studies.

This study aims to mine the regularity of traditional Chinese medicine(TCM) prescriptions for sick sinus syndrome(SSS) and provide a reference for clinical syndrome differentiation and treatment. The relevant papers were retrieved from CNKI, Wanfang, VIP, and SinoMed with the time interval from inception to January 31, 2023. The relevant information from qualified papers was extracted to establish a library. Lantern 5.0 and Rstudio were used to analyze the latent structure and association rules of TCMs with the frequency ≥3%, which combined with frequency descriptions, were used to explore the rules of TCM prescriptions for SSS. A total of 192 TCM prescriptions were included, involving 115 TCMs with the cumulative frequency of 1 816. High-frequency TCMs include Aconiti Lateralis Radix Praeparata, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Astragali Radix, and Salviae Miltiorrhizae Radix et Rhizoma. The high-frequency medicines mainly had the effects of tonifying, releasing exterior with pungent-warm, and activating blood and resolving stasis. The analysis of the latent structure model yielded 13 hidden variables, 26 hidden classes, 8 comprehensive cluster models, and 21 core prescriptions. Accordingly, the common syndromes of SSS were inferred as heart-Yang Qi deficiency, heart-spleen Yang deficiency, heart-kidney Yang deficiency, Yang deficiency and blood stasis, both Qi and Yin deficiency and blood stasis, and Yin and Yang deficiency. The analysis of association rules predicted 30 strong association rules, among which Ginseng Radix et Rhizoma-Aconiti Lateralis Radix Praeparata had the highest support. SSS is a syndrome with Yang deficiency and Qi deficiency as the root causes and cold, phlegm, and stasis as the manifestations. The clinical treatment of SSS should focus on warming Yang and replenishing Qi, which should be supplemented with the therapies of activating blood and resolving stasis, warming interior and dissipating cold, or regulating Qi movement for resolving phlegm according to the patients' syndromes.

Since the implementation of drug registration in China, the classification of Chinese medicine has greatly met the needs of public health and effectively guided the transformation, inheritance, and innovation of research achievements on traditional Chinese medicine(TCM). In the past 30 years, the development of new Chinese medicine has followed the registration transformation model of " one prescription for single drug". This model refers to the R&D and registration system of modern drugs, and approximates to the " law-abiding" medication method in TCM clinic, while it rarely reflects the sequential therapy of syndrome differentiation and comprehensive treatment with multiple measures. In 2017, Opinions on Deepening the Reform of Review and Approval System and Encouraging the Innovation of Drugs and Medical Devices released by the General Office of the CPC Central Committee and the General Office of the State Council pointed out that it is necessary to " establish and improve the registration and technical evaluation system in line with the characteristics of Chinese medicine, and handle the relationship between the traditional advantages of Chinese medicine and the requirements of modern drug research". Therefore, based on the development law and characteristics of TCM, clinical thinking should be highlighted in the current technical requirements and registration system of research and development of Chinese medicine. Based on the current situation of registration supervision of Chinese medicine and the modern drug research in China, the present study analyzed limitations and deficiency of " one prescription for single drug" in the research and development of Chinese medicine. Additionally, a new type of " series prescriptions" was proposed, which was consistent with clinical thinking and clinical reality. This study is expected to contribute to the independent innovation and high-quality development of the TCM industry.

OBJECTIVE@#To summarize the medication rules of Chinese herbs to treat heart failure with preserved ejection fraction (HFPEF) based on data mining and to provide references for clinical utilization.@*METHODS@#The China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), VIP database (VIP), Chinese Biomedical Literature (CBM), PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021 to identify relevant literature on treating HFPEF with Chinese herbs. Microsoft Excel 2019 was used to set up a database, and then, association rule analysis and hierarchical cluster analysis were performed by using apriori algorithm and hclust function respectively in R-Studio (Version 4.0.3).@*RESULTS@#A total of 182 qualified papers were included, involving a total of 92 prescriptions, 130 Chinese herbs, and 872 individual herbs prescribed, with an average of 9.5 herbs per prescription. The six most frequently prescribed herbs were Astragali Radix (Huangqi), Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Glycyrrhizae Radix Et Rhizoma (Gancao), Cinnamomi Ramulus (Guizhi), and Ginseng Radix Et Rhizoma (Renshen). There were 35 herbs used more than 5 times, involving 11 efficacy categories. The top three categories were deficiency-tonifying herbs, blood-activating and stasis-removing herbs, and dampness-draining diuretic herbs. The most commonly used herbs were mainly warm and sweet. The primary meridian tropisms were Lung Meridian, Heart Meridian and Spleen Meridian. Association rule analysis yielded 26 association rules, such as Astragali Radix (Huangqi) & Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Cinnamomi Ramulus (Guizhi) & Atractylodis Macrocephalae Rhizoma (Baizhu). Hierarchical cluster analysis yielded four herb classes, and their functions were mainly qi-replenishing and yang-warming, blood-activating and diuresis-inducing.@*CONCLUSIONS@#HFPEF is the syndrome of root vacuity and tip repletion, and its core pathogenesis is "deficiency", "stasis", and "water", with "deficiency" being the most principal, which is closely related to Xin (heart), Fei (Lung), and Pi (Spleen). The treatment of this disease occurs by improving qi, warming yang, activating blood and inducing diuresis. Astragali Radix (Huangqi) with Salviae Miltiorrhizae Radix Et Rhizoma (Danshen) is the basic combination of herbs applied.

To systematically evaluate the clinical efficacy and safety of Xinmailong Injection in the treatment of heart failure after acute myocardial infarction. Seven Chinese and English databases, namely CNKI, VIP, Wanfang, SinoMed and PubMed, EMbase, Cochrane Library, were retrieved from the establishment of the database to March 2020. Randomized controlled trials for Xinmailong Injection in the treatment of heart failure after acute myocardial infarction were screened out. Cochrane collaboration network bias risk assessment tool was used to evaluate the literature quality of the studies included, and RevMan 5.3 software was used for Meta-analysis. A total of 926 relevant literatures were retrieved, and 12 studies were finally included, involving 972 patients, including 486 patients in the treatment group and 486 patients in the control group. The quality of the literatures included was generally low. The results of Meta-analysis showed that Xinmailong Injection combined with Western medicine could decrease the levels of BNP(SMD=-5.90, 95%CI[-8.45,-3.36], P<0.000 01) and NT-proBNP(SMD=-2.28, 95%CI[-3.13,-1.43], P<0.000 01) and decrease the levels of cTnI(SMD=-2.91, 95%CI[-4.21,-1.60], P<0.000 1), increase LVEF(MD=4.67, 95%CI[4.19, 5.16], P<0.000 01), increased 6 MWT(MD=73.90, 95%CI[67.51, 80.28], P<0.000 01], decreased LVEDD(MD=-5.46, 95%CI[-9.66,-1.25], P=0.01), reduce the level of serum inflammatory factor(hs-CRP, CRP, IL-6). In terms of safety, less adverse reactions occurred in the study, with no impact on the treatment. The results showed that clinical use of Xinmailong Injection combined with Western medicine in the treatment of heart failure after acute myocardial infarction can further alleviate clinical symptoms and relevant indexes, with less adverse reactions. However, due to the limitations in quantity and quality of the clinical studies included, the positive results can only be used as a hint and reference for clinical diagnosis and treatment, and more high-quality studies are needed to further confirm its efficacy.

ABSTRACT
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.
ABSTRACT
OBJECTIVE To explore the curative effect and mechanism of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. METHODS The patients with coronary heart dis?ease of Qi deficiency and blood stasis syndrome were treated with Yiqi Huoxue decoction for 3 months, and the changes of cardiac function were observed. 61 serum samples (including 29 cases of disease group and 32 cases of Yiqi Huoxue expression group) were analyzed by non labeled proteomics. The disease group was used as the control group, and the protein with expression level difference of more than 1.2 folds (P<0.05) was screened. The molecular function, biologi?cal pathway and protein interaction of the different proteins were analyzed by bioinformatics, so as to identify the molecu?lar and biological pathway of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. RESULTS Clinical treatment found that Yiqi Huoxue decoction can improve TCM syndrome score and left ventricular ejection fraction, regulate blood glucose and blood lipid levels, prolong thrombin time, and improve heart function. The results of proteomic quantitative analysis showed that there were 69 proteins with different expression levels in the disease group. Bioinformatics analysis results showed that Yiqi Huoxue decoction may regulate ApoA1, alpha-2 and other proteins to act on HDL assembly, platelet degradation, PI3K Akt signaling pathway, and then play a therapeutic role in coronary heart disease with Qi deficiency and blood stasis syndrome. CONCLUSION Yiqi Huoxue decoction can effectively improved the heart function decline caused by Qi deficiency and blood stasis syn?drome of coronary heart disease. It mainly act on energy metabolism and platelet activation pathway by activating HDL assembly and platelet degradation signal pathway proteins. This study can provide reference for the follow-up treatment mechanism of Qi deficiency and blood stasis syndrome of coronary heart disease.
ABSTRACT
Objective:To systematically sort out and summarize the medication rules of clinical prescriptions for coronary heart disease with heart failure of Qi deficiency and blood stasis syndrome,and to provide reference for selecting prescriptions and medications for the treatment of coronary heart disease (CHD) with traditional Chinese medicine (TCM). Method:All relevant literature concerning the treatment of CHD with compound TCM prescriptions for Qi deficiency and blood statis syndrome from 2000 to 2020 were retrieved from the China National Knowledge Network (CNKI),WanFang database (WanFang),and VIP journal database (VIP),and the names of prescriptions and drug components were extracted,followed by the frequency of drug use and drug category. Association rules of high-frequency drugs were analyzed by SPSS 18.0,and systematic clustering analysis was conducted by SPSS 21.0. Result:Finally,41 qualified literature articles covering 35 prescriptons and 66 drugs were included in the study. The total frequency of the drugs was 433 times. Among them,there were a total of 25 traditional Chinese medicines with a frequency of ≥5 times. The top 3 frequently used Chinese medicines were Astragali Radix (8.8%),Salviae Miltiorrhizae Radix et Rhizoma (7.2%),Chuanxiong Rhizoma (5.8%). A total of 15 types of drugs were involved,among which tonic drugs (31.4%),blood promoting and blood stasis drugs (28.2%),and hydration and dampening drugs (7.6%) were used most frequently. The association rule analysis of traditional Chinese medicines with frequency of ≥ 5 showed that there were 13 pairs of binomial associations in 25 traditional Chinese medicines,with Astragali Radix in combination with Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Carthami Flos,et al. There were 8 groups of three associations,with Astragali Radix,Salviae Miltiorrhizae Radix et Rhizoma,and Chuanxiong Rhizoma as the main combinations. A systematic clustering analysis showed that the clustering effect was best when the 25 traditional Chinese medicines were clustered into 5 categories. Conclusion:The treatment of coronary heart disease with heart failure of Qi deficiency and blood stasis syndrome is based on replenishing qi and activating blood circulation,supplemented by warming yang,diuresis,and phlegm-resolving drugs,which can enhance the clinical efficacy. Two basic prescriptions of Buyang Huanwutang and Si junzitang are extracted. Other combinations of prescriptions and drugs can provide references for the clinical treatment of coronary heart disease with heart failure.
ABSTRACT
To systematically evaluate the efficacy and safety of Xinmailong Injection in the treatment of coronary heart disease complicated with heart failure. Seven databases,namely CNKI, VIP,WanFang,SinoMed,PubMed,EMbase,Cochrane Library, were retrieved by computer for collecting the randomized controlled trials about Xinmailong Injection in the treatment of coronary heart disease complicated with heart failure. The literatures were screened out, data was extracted, and the methodological quality evaluation was conducted by 2 researchers independently according to inclusion and exclusion criteria. RevMan 5.3 software was used for Meta-analysis and corresponding description analysis. A total of 19 studies involving 1 922 patients were included, including 967 cases in the trial group and 955 cases in the control group. All the clinical studies showed a low quality. Meta-analysis results showed that Xinmailong Injection combined with conventional treatment could better reduce the BNP level(SMD=-3.34, 95%CI[-4.06,-2.63]) in patients of coronary heart disease complicated with heart failure or NT-proBNP level, improve the cardiac function(RR=1.23,95%CI[1.18,1.29]) and LVEF(MD=6.85,95%CI[4.93,8.76]),increase 6 MWT(MD=24.34, 95%CI[16.05, 32.64]) and VEGF(MD=26.39,95%CI[24.30,28.49]),and decreased LVEDD(MD=-4.06, 95%CI[-6.33,-1.80]). And subgroup analysis suggested that the course of treatment may be related to the increase of LVEF. This study found that Xinmailong Injection for coronary heart disease complicated with heart failure can further alleviate clinical symptoms and relevant indicators, with no serious adverse reaction. However, it still needs the support of well-designed multicenter, double-blind and high-quality clinical trials.

In 2013,China pharmaceutical regulatory department issued guiduance on postmarketing drug safety monitoring for industry. It aimed to encourage industry to carry out postmarketing drug safety monitoring including hospital-based intensive monitoring of postmarketing Chinese patent medicine. Subsequently,more and more such kind of studies have been performed all over China. However,in view of the current situation in this field,the development of hospital-based intensive monitoring of postmarketing Chinese patent medicine lacks standardization,such as unreasonable design,omission of reports about adverse drug reactions,inadequate process of quality control,non-standardized interpretation of adverse reactions,etc. Therefore,it is necessary to formulate relevant technical specifications to guide this area. The developing of this technical specification refered to the international post-marketing safety monitoring model and advanced design concepts and methods. We developed it under the guidance of relevant laws,regulations and technical documents in China. Meanwhile the characteristics of Chinese patent medicines and the real situation in this area were considered. The aim of this technical specification is to obtain the incidence,type,degree and clinical manifestation of adverse drug reactions of Chinese patent medicines,to find new risk signals of adverse reactions,to identify risk factors,and to provide a basis for the formulation of risk management and control plans. This specification has been approved by China association of Chinese medicine which is numbered T/CACM011-2016.

Along with the increase of clinical application, the safety of traditional Chinese medicine gained more and more attentions. In particular, the safety evaluation of Chinese medical injections has become a mandatory task should be completed by pharmaceutical companies under the supervision of China Food and Drug Administration(CFDA). Due to the weak foundation of previous studies, the safety issues of Chinese medical injections have not been fully understood, and lack of scientific and rational risk management programs. Clinical safety centralized monitoring(CSCM) is an important method for post-market safety evaluation of Chinese medicine. Due to the lack of appropriate norms and procedures, the quality of similar research is uneven, and the results vary. Combined with practical experience with experts' suggestions, we developed this expert consensus on the design and implementation of CSCM from three stages (design, implementation and report) with 20 technical points, which will provide technical support for future CSCM studies.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effects of Jiashen Prescription (, JSP) on myocardial infarction (MI) size and cardiac function at the early stage of MI in rats.</p><p><b>METHODS</b>One hundred male Sprague-Dawley rats were subjected to sham-operation or MI induced by ligating the left anterior descending coronary artery. The rats with MI were treated with vehicle, JSP 3 and 6 g/(kg·d), or losartan 10 mg/(kg·d) for 1 week.</p><p><b>RESULTS</b>Compared with the vehicle-treated MI rats, 6 g/(kg·d) JSP reduced MI size 3 days after MI (P<0.05), and attenuated the MI-induced increases in left ventricular end-diastolic and end-systolic dimension and decreases in fractional shortening and ejection fraction 1 week after MI (P<0.05). In addition, 6 g/(kg·d) JSP and losartan were equally effective in reducing MI size and enhancing cardiac functional recovery.</p><p><b>CONCLUSION</b>JSP reduces MI size and improves cardiac function after MI, suggesting that JSP has potential as a therapy for MI.</p>

<p><b>OBJECTIVE</b>To determine the effects of transient receptor potential vanilloid type 1 (TRPV1) channel ablation and a chemokine receptor 2 (CCR2) antagonist on salt-sensitive hypertension-induced renal injury.</p><p><b>METHODS</b>Wild-type (WT) and TRPV1-null mutant (TRPV1(-/-)) mice were subjected to uninephrectomy and deoxycorticosterone acetate (DOCA)-salt treatment for 4 weeks with or without a CCR2 antagonist, RS504393 (n=8 for all the 4 groups). Sham WT and TRPV1(-/-) mice (both n=7) underwent uninephrectomy without receiving DOCA and saline. Systolic blood pressure, urinary excretion of albumin, 8-isoprostane and creatinine clearance for 24 hours were assayed during the experimental period and at the end of the 4-week treatment. The morphological analysis was performed in renal histological sections, including glomerulosclerosis, tubulointerstitial injury, and monocyte/macrophage infiltration.</p><p><b>RESULTS</b>Compared to the corresponding control mice, DOCA-salt treatment in both WT and TRPV1(-/-) mice led to increased systolic blood pressure (SBP), enhanced urinary excretion of albumin and 8-isoprostane, decreased creatinine clearance, increased glomerulosclerosis and tubulointerstitial injury associated with enhanced monocyte/macrophage infiltration (all P<0.05), all of which were much more severe in TRPV1(-/-) mice compared to WT mice with the exception of blood pressure (all P<0.05). RS5043943 attenuated DOCA-salt-induced changes in renal function and morphology in WT and TRPV1(-/-) mice (all P<0.05). There was no difference in blood pressure among DOCA-salt WT and TRPV1(-/-) mice with or without RS505393 with the exception of sham WT and TRPV1(-/-) mice (all P>0.05).</p><p><b>CONCLUSIONS</b>CCR2 antagonist inhibits DOCA-salt-induced renal injury and monocyte/macrophage infiltration in WT and TRPV1(-/-) mice with the greater in the latter strain. Activation of TRPV1 attenuates salt-sensitive hypertension-induced renal injury possibly via inhibition of CCR2-induced monocyte/macrophage infiltration.</p>

<p><b>OBJECTIVE</b>To determine the role of chemokine receptor 2 (CCR2) in the development of salt-sensitive hypertension-induced renal damage.</p><p><b>METHODS</b>We investigated the renal damage induced by uninephrectomy and deoxycorticosterone acetate (DOCA)-salt in mice treated with or without a selective CCR2 antagonist RS504393 for 4 weeks. Sham mice underwent uninephrectomy without receiving DOCA and saline. Systolic blood pressure, urinary excretion of albumin and 8-isoprostane, creatinine clearance, glomerulosclerosis, renal tubulointerstitial injury, and renal monocyte/macrophage infiltration were measured.</p><p><b>RESULTS</b>DOCA-salt treatment led to increased systolic blood pressure, increased urinary excretion of albumin and 8-isoprostane, decreased creatinine clearance, glomerulosclerosis, renal tubulointerstitial injury, and renal monocyte/macrophage infiltration compared with the sham mice (P<0.05). All of them were prevented by CCR2 inhibition (P<0.05).</p><p><b>CONCLUSION</b>Blockade of CCR2 prevents renal damage induced by DOCA-salt treatment, suggesting that CCR2-mediated monocyte/macrophage infiltration may contribute to salt-sensitive hypertension-induced renal injury.</p>

<p><b>OBJECTIVE</b>To assess a multi-center study effectiveness of clinical pathways based on integrative medicine (IM) for chronic heart failure (CHF) patients.</p><p><b>METHODS</b>A combined method of historical control study and clinical study on concurrent control was used. After the standard management for clinical pathways was carried out in four hospitals at home, the effects on hospitalization days, medical expenses, clinical efficacy, patient satisfaction, and quality of life were assessed.</p><p><b>RESULTS</b>Results of non-concurrent historical control study showed that: the hospital stay was significantly shorter in the pathways group than in the retrospective group (12.59 days vs 18.44 days), and the total cost of hospitalization was significantly reduced in the pathways group (yen 9 051.90 vs yen 11 978.40), showing statistical difference (P < 0.01). Moreover, the effect on the heart function was better in the pathways group than in the retrospective group (the markedly effective rate: 45.60% vs 21.90%; the total effective rate: 96.80% vs 86.10%), showing statistical difference (P < 0.01). Results of clinical study on concurrent control showed that the hospital stay was significantly shorter in the pathways group than in the control group (11.19 days vs 13.21 days), showing statistical difference (P < 0.05). The average total cost of hospitalization was significantly lower in the pathways group than in the control group (yen 8 656.80 vs yen 11 609.70), showing statistical difference (P < 0.01). As for clinical efficacy of Chinese medical syndrome, the total effective rate was higher in the pathways group than in the control group (97.10% vs 93.62%), showing statistical difference (P < 0.05). The markedly effective rate of heart function was better in the pathways group than in the control group, showing statistical difference (49.30% vs 38.30%, P < 0.05). The overall satisfaction was higher in the pathways group than in the conventional group (P < 0.01). There was no statistical difference in the mortality within 3 months after discharge from hospital, and the readmission rate due to heart failure between the two groups (P > 0.05). But there was statistical difference in the quality of life (P < 0.05).</p><p><b>CONCLUSION</b>The pathway could shorten the hospitalization time, decrease the cost of hospitalization, improve the clinical efficacy, improve patients' quality of life and satisfaction, therefore, it could be spread nationwide.</p>
