Mohammed SAD, Hanxing L, Fang L, Algradi AM, Alradhi M, Safi M, Shumin L. Integrated Chinese herbal medicine with Western Medicine versus Western Medicine in the effectiveness of primary hypertension treatment: A systematic review and meta-analysis of randomized controlled trials. JOURNAL OF ETHNOPHARMACOLOGY 2023; 300:115703. [PMID: 36096347 DOI: 10.1016/j.jep.2022.115703] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Revised: 07/30/2022] [Accepted: 09/05/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Integrated Chinese herbal medicine (CHM) and Western Medicine (WM) treatments have been used for primary hypertension (PHTN) patients in China. Currently, there are many randomized control trials (RCTs) published regarding the effect of CHM and WM on PHTN, which indicated that combining Chinese with WM was effective and safe for PHTN when compared with WM alone, but the quality of evidence was insufficient, and there is no clear information and summary are available for these RCTs assessing the effectiveness of CHM with WM versus WM in patients with PHTN. OBJECTIVES This systematic study and meta-analysis aimed to evaluate the effectiveness and safety of CHM combined with WM in comparison with WM in reducing systolic and diastolic blood pressure for patients with PHTN. METHODS The information of this study was searched from electronic databases (PubMed, COCHRANE, EMBASE, Ovid, CNKI, VIP, Wanfang, and CBM). The markedly effective and effective terms were according to Guiding Principles for Clinical Research of New Chinese Medicines. Two investigators independently reviewed each trial. The Cochrane risk of bias assessment tool was used for quality assessment, and RevMan 5.4 was used for meta-analysis. RESULTS In this study, a total of 29 studies that included 2623 patients were recorded. The study results displayed that the clinical effectiveness in the treatment of hypertension patients from the integrated medicines was considerably higher than that with WM alone, clinical effective (RR 1.23, 95% CI [1.17, 1.30], P < 0.00001), and markedly effective (ME) in the patients (RR 1.66, 95% CI [1.52, 1.80], and P < 0.00001). Random effect in SBP (MD 7.91 mmHg,[6.00, 983], P < 0.00001) and DBP (MD 5.46 mmHg, [3.88, 6.43], P < 0.00001), a subgroup analysis was carried out based on the type of intervention, duration of treatment, and CHM formulas that showed significance. Furthermore, no severe side effects were reported, and no patients stopped treatment or withdrawal due to any severe adverse events. CONCLUSION Compared to WM alone, the therapeutic effectiveness of CHM combined with WM is significantly improved in the treatment of hypertension. Additionally, CHM with WM may safely and efficiently lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) in individuals with PHTN. However, rigorous randomized controlled trials with a large sample, high quality, long duration of treatment, and follow-up are recommended to strengthen this clinical evidence.

Front Cardiovasc Med 2022; 9:1038480. [PMID: 36465462 PMCID: PMC9709460 DOI: 10.3389/fcvm.2022.1038480] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Accepted: 10/27/2022] [Indexed: 09/19/2023] Open
Abstract
Hypertension is the most common chronic disease. A large amount of evidence showed that traditional Chinese medicine (TCM) method of tonifying kidney (TK) combined with routine treatment is more effective and safer in the treatment of hypertension. This study integrated meta-analysis, data mining, and network pharmacology to explore the efficacy and potential mechanisms of TK in the treatment of hypertension. Meta-analysis was performed to explore the efficacy and safety of TK combined with routine treatment in the treatment of hypertension. Data mining was used to screen the core herbs of the TK. Network pharmacology was used to predict the antihypertensive mechanism of TK core herbs. A total of 18 studies with 2,024 patients were included in this study. Meta-analysis showed that TK combined with routine treatment was superior to routine treatment alone in lowering blood pressure (systolic and diastolic blood pressures), lowering blood lipids (total cholesterol, triglyceride, low-density lipoprotein cholesterol), improving vascular endothelial functions (nitric oxide, endothelin) and TCM symptoms (headache dizziness, soreness, and weakness of waist and knees). In addition, TK was safe and has no obvious adverse reactions. Data mining showed that the core herbs of TK were Eucommia ulmoides Oliv. (Duzhong), Vitex negundo L. (Huangjing), Taxillus chinensis (DC.) Danser (Sangjisheng), Ligustrum lucidum W.T.Aiton (Nuzhenzi), Astragalus mongholicus Bunge (Huangqi), Rehmannia glutinosa (Gaertn.) DC. (Shudihuang). Network pharmacology predicted that core herbs antihypertensive components were oleanolic acid, ursolic acid, and civetone, and the antihypertensive targets were NOS3, NOS2, MMP9, TNF, PTGS2, HMOX1. In addition, the antihypertensive targets were enriched in cGMP-PKG signaling pathway, calcium signaling pathway, aldosterone-regulated sodium reabsorption, HIF-1 signaling pathway. In conclusion, TK combined with routine treatment for hypertension is effective and safe. The mechanism of TK may be related to GMP-PKG signaling pathway, calcium signaling pathway, aldosterone-regulated sodium reabsorption. On the premise of syndrome differentiation and treatment, it is promising to treat hypertension with TK.

Current Status and Evaluation of Randomized Clinical Trials of Traditional Chinese Medicine in the Treatment of Cardiovascular Diseases. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6181862. [PMID: 35069763 PMCID: PMC8769817 DOI: 10.1155/2022/6181862] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 09/18/2021] [Accepted: 12/08/2021] [Indexed: 11/29/2022]
Abstract
Traditional Chinese medicine has long been applied to various diseases in China for a few thousand years. In recent years, its market has gradually developed from Asian countries to Western countries. At present, due to the lack of evidence-based medicine research, the effect of traditional Chinese medicine on the prevention and treatment of cardiovascular disease remains unclear. In evaluating the efficacy and safety of drugs, randomized controlled clinical trials (RCTs) are recognized as the gold standard for testing the effectiveness and safety of treatments and could offer the best evidence for the formulation of clinical treatment guidelines. Although traditional Chinese medicine has long been used to treat cardiovascular diseases, the research on the application of RCT to test the combination of traditional Chinese and Western medicine therapy or single traditional Chinese medicine therapy started late, and the number is comparably small. In order to summarize and objectively evaluate the research results of integrated traditional Chinese and Western medicine in intervention of cardiovascular diseases, we reviewed the literature of RCTs in this field by searching some Chinese and English databases and put forward some suggestions for the future development and research of traditional Chinese medicine.

Abstract
Traditional Chinese medicine (TCM) prescriptions lack standardization due to the complex composition of the prescribed herbs, the unclear mechanism of the formulas, and a lack of scientific data to support the dose-response relationship. Here, we proposed a new clinical strategy of dosage modification for TCM prescriptions to evaluate the clinical efficacy and guide the clinical medication. This study used two TCM prescriptions for the treatment of newly diagnosed type 2 diabetes mellitus (T2DM) to explore the key indications and the most appropriate critical values of dosage modification by analyzing two randomized controlled trials (RCTs). In this study, the indications refer to a change in the indicators from baseline at a certain time point (week 4, week 8, week 12), which could predict the change in outcome indicators, and the critical values refer to the change ranges closely related to the decrease in HbA1c at week 12. In Study 1, the correlation analysis between the change range of indicators at three time points (weeks 4, 8, and 12) from baseline and the decrease in HbA1c at week 12 from baseline (HbA1c 012) was carried out to screen the related indications. Next, we evaluate the related indications and the respective critical values to determine the key indicators, indications, and the most appropriate critical value. We conducted a correlation between the change range of key indicators (obtained from the result of Study 1) at three time points from baseline and HbA1c 012 to screen the key indications in the drug group, high-dose group, and low-dose group in Study 2. Key indications with critical values were determined to investigate the most appropriate critical value in the three groups separately. In Study 1, the key indicator was FBG, the key indication was FBG 04, and the most appropriate critical value was 0.5 mmol/L. In Study 2, the key indication was FBG 04 and the most appropriate critical value was 0.6 mmol/L in the drug group. In the high-dose group, the key indication was FBG 04, and the most appropriate critical value was 0.3 mmol/L. In the low-dose group, the key indication was FBG08, and the most appropriate critical value was 0.1 mmol/L. In addition, we summarized a verification strategy for dosage modification.

Cost-effectiveness analysis of combining traditional Chinese medicine in the treatment of hypertension: compound Apocynum tablets combined with Nifedipine sustained-release tablets vs Nifedipine sustained-release tablets alone. BMC Complement Med Ther 2020; 20:330. [PMID: 33153455 PMCID: PMC7643403 DOI: 10.1186/s12906-020-03091-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Accepted: 09/17/2020] [Indexed: 11/17/2022] Open
Abstract
Background We evaluated the long-term cost-effectiveness of antihypertensive traditional Chinese medicines (TCMs) and to compare the cost-effectiveness of a combined treatment consisting of compound Apocynum tablets and Nifedipine sustained-release tablets with the cost-effectiveness of treatment with Nifedipine sustained-release tablets alone. Methods A Markov model was used to simulate the potential incremental cost-effectiveness per quality-adjusted life year (QALY) to be gained from compound Apocynum tablets and Nifedipine sustained-release tablets compared with Nifedipine sustained-release tablets alone. Model parameter estimates were informed by previously published studies. The direct medical costs of outpatients with hypertension were estimated from the health care provider’s perspective. A 5% annual discount rate was applied to both costs and QALYs. Results TCMs combined with Nifedipine sustained-release tablets group generated a total 20-year cost of 11,517.94 RMB (US $1739.87), whereas Nifedipine sustained-release tablets alone group resulted in a 20-year cost of 7253.71 RMB (US $1095.73). TCMs combined with Nifedipine sustained-release tablets group resulted in a generation of 12.69 QALYs, whereas Nifedipine sustained-release tablets alone group resulted in 12.50. The incremental cost-utility ratio was 22,443.32 RMB (US $3390.23) per QALY. Considering the threshold of 1 GDP per capita in China in 2018 (US $9764.95), the combination of compound Apocynum tablets and Nifedipine sustained-release tablets was a cost-effective strategy. One-way and probabilistic sensitivity analysis showed unchanged results over an acceptable range. Conclusions Combining Traditional Chinese Medicines with chemical medicines is more cost-effective strategy in the treatment of hypertension.

Abstract
Objective Vascular endothelium plays a fundamental role in regulating endothelial dysfunction, resulting in structural changes that may lead to adverse outcomes of hypertension. The aim of this study was to systematically evaluate the effect of a combination of Chinese herbal medicine (CHM) and Western medicine on vascular endothelial function in patients with hypertension. Methods We systematically searched the literature for studies published in Chinese and English in PubMed, Embase, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China Knowledge Resource Integrated Database, Wanfang Data, and China Science and Technology Journal Database. Databases were searched using terms concerning or describing CHM, hypertension, vascular endothelium, and randomized controlled trials. RevMan 5.3.0 was used for data analysis. If the included studies were sufficiently homogeneous, quantitative synthesis was performed; if studies with different sample sizes and blind methods were used, subgroup analyses were performed. GRADEpro was selected to grade the current evidence to reduce bias in our findings. Results In this review, 30 studies with 3,235 patients were enrolled. A relatively high selection and a performance bias were noted by risk of bias assessments. Meta-analysis showed that the combination of CHM and conventional Western medicine was more efficient than conventional Western medicine alone in lowering blood pressure (risk ratio, 1.21; 95% CI, 1.16 to 1.26) and increasing nitric oxide (95% CI, 1.24 to 2.08; P < 0.00001), endothelin-1 (95% CI, −1.71 to −1.14; P < 0.00001), and flow-mediated dilation (95% CI, 0.98 to 1.31; P <0.00001). No significant difference was observed between the combination of CHM and conventional Western medicine and conventional Western medicine alone for major cardiovascular and cerebrovascular events. CHM qualified for the treatment of hypertension. The GRADEpro presented with low quality of evidence for the available data. Conclusion CHM combined with conventional Western medicine may be effective in lowering blood pressure and improving vascular endothelial function in patients with hypertension. To further confirm this, more well-designed studies with large sample sizes, strict randomization, and clear descriptions about detection and reporting processes are warranted.

Abstract
OBJECTIVE This study aims to investigate the effect of nimodipine combined with betahistine on the levels of CRP and other inflammatory cytokines, as well as vascular endothelial function in patients with hypertensive cerebral vasospasm. METHODS A total of 80 patients with hypertensive cerebral vasospasm from March 2016 to September 2018 were enrolled and randomly equally divided into two groups. At 1 week before enrollment, the application of all antihypertensive drugs was stopped. Then amlodipine tablets were used in control group, based on which nimodipine tablets were applied in observation group. All the patients included were followed up for 1 month. The changes in the cerebral vasospasm index in the course of treatment as well as inflammatory cytokines and indicators related to vascular endothelial function at 1 month after treatment were measured and compared between the two groups. The correlations of the cerebral vasospasm index with the changes in inflammatory cytokines and vascular endothelial function-related factors in the body were analyzed. Finally, the effective rates of blood pressure regulation and cerebral vasospasm treatment were compared, while the adverse reactions and the overall clinical treatment effect of the two groups were evaluated. RESULTS The cerebral vasospasm indexes in observation group were significantly lower than those in control group at 3 d, 1 week and 1 month after treatment (p < 0.05). At 1 month after treatment, the levels of inflammatory cytokines such as high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in observation group were significantly reduced compared to those in control group (p < 0.05). As for vascular endothelial function-related indicators, the endothelin-1 (ET-1) level in observation group was markedly lower than that in control group, whereas the level of nitric oxide (NO) was statistically higher than that in control group (p < 0.05). The cerebral vasospasm index was statistically positively correlated with changes in hs-CRP, IL-6, TNF-α and ET-1 (p < 0.05), but negatively correlated with changes in NO (p < 0.05). Besides, the effective rates of blood pressure regulation and cerebral vasospasm treatment in observation group were significantly higher than those in control group (p < 0.05). The overall treatment effective rate in observation group was markedly higher than that in control group (p < 0.05), and there were no significant differences of adverse reactions between the two groups (p > 0.05). CONCLUSION For the treatment of hypertensive cerebral vasospasm, combined application of betahistine on the basis of nimodipine can effectively reduce the body's aseptic inflammatory responses, improve vascular endothelial function and increase the cerebral circulation blood flow, which offers a favorable strategy for clinical therapy.

Abstract
BACKGROUND Essential hypertension is one of the most common chronic diseases in the world and a major risk factor for cardiovascular and cerebrovascular diseases. Hypertension often leads to a variety of complications, of which vascular endothelial dysfunction is an important part. Traditional Chinese medicine (TCM) combined with western medicine can significantly improve vascular endothelial function in patients with hypertension, but it has not been systematically evaluated for efficacy and safety of essential hypertension. Therefore, we aim to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of TCM combined with western medicine in improving vascular endothelial function in patients with essential hypertension. METHODS We will search PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Excerpta Medica Database (EMBASE), China National Knowledge Infrastructure Database (CNKI), Wanfang Database, China Science Journal Database (VIP Database) and China Biomedical Literature Database (CBM). Clinical trial registrations, potential grey literature, related conference abstracts, and reference lists of identified studies will also be retrieved. The electronic database will be searched for literatures published from the beginning to October 2018. Based on the heterogeneity test, data integration is performed using a fixed effect model or a random effects model. Changes in blood pressure and endothelial function will be assessed as primary outcomes. Drug use, disease progression and adverse events will be assessed as secondary outcomes. RevMan V.5.3.5 will be used for meta-analysis. RESULTS This systematic review and meta-analysis will provide high-quality evidence from a variety of aspects, including efficacy, blood pressure, vascular endothelial function and adverse reactions, to assess the efficacy and safety of TCM combined with western medicine in patients with hypertension. CONCLUSION This systematic review will determine whether TCM combined with western medicine provides evidence for effective intervention of vascular endothelial function in patients with essential hypertension. ETHICS AND DISSEMINATION This systematic review and meta-analysis of randomized controlled trials does not require ethical recognition, and the results of this paper will be published in an open access, internationally influential academic journal.

Abstract
Objective To summarize the characteristics and the outcomes of the Randomized Placebo-Controlled Trials of Chinese Herbal Medicine Granules manufactured by China Resources Sanjiu Pharmaceutical Co., Ltd. Methods Databases including China National Knowledge Infrastructure, VIP, Wanfang, PubMed, Cochrane Library, and clinicaltrials.gov were searched in March 2018 for relevant randomized controlled trials (RCTs). Two reviewers independently screened for and selected studies, extracted data, and checked data extraction. Methodological quality was evaluated using the Cochrane Risk of Bias tool. For the outcome, the characteristics of the study, the cure rate, the effectiveness rate, and advert events were described with a method of bibliometrics. Also, we performed meta-analysis only if there were ≥2 studies treated by the same intervention and evaluated by the same outcome. Results A total of 40 placebo-controlled RCTs treated for 17 diseases were included in our analysis involving 4,632 patients. 16 of 19 studies treated by CHM granules only showed positive result in patients with HBV, HCV, fever, depression, nonalcoholic fatty liver disease, AIDS, and asthma while negative result was shown in patients with migraine. 17 of 21 studies treated by combination therapy against conventional therapy showed positive result in patients with HBV, herpes simplex keratitis, COPD, liver cirrhotic ascites, Parkinson's disease, and diabetic peripheral neuropathy while negative result was shown in patients with myasthenia gravis, angina pectoris, and depression. The pooled result cannot demonstrate that the notifying kidney formula granules had the superior effect with placebo on the clearance of serum HBV DNA and HBeAg in HBV carriers with a RR (and the 95% CI) of 2.97 [0.74,11.91] and 1.99 [0.93,4.29], respectively. But, the CHM granules can reduce within-group HBV DNA levels by more than 2 lgIU/ml; the RR (and 95% CI) was 4.64 [2.89,7.45]. Qizhu granules had a significant effect on clearance of HCV RNA with a RR (and 95% CI) of 6.26 [2.16,18.16]. And, the heat-clearing and detoxifying formula granules were superior to placebo in resolution of cold symptom among patients with fever with a RR and 95% CI of 2.58 [1.40,4.74]. Based on the conventional therapy, the pooled result demonstrated that the Regulating liver formula granules were superior to placebo on the clearance of serum HBeAg in chronic hepatitis B patients with a RR (and the 95% CI) of 1.73 [1.30,2.31]. The EeChen decoction granules were superior to placebo in COPD patients with a RR (and the 95% CI) of 1.13 [1.06,1.22]. 28 of the 40 studies reported adverse events. There were 51 adverse events in CHM formula granules group or combination group (n=2,483) and 26 in control group (n=2,122) totally. Most of the adverse symptoms spontaneously resolved after completing the courses of treatment and the other adverse symptoms improved after symptomatic treatment. Conclusion 16 of 19 studies treated by CHM granules only showed positive result in 7 diseases and negative result in 1 disease. 17 of 21 studies treated by combination therapy against conventional therapy showed positive result in 6 diseases and negative result in 3 diseases. However, both the absolute and relative effectiveness of CHM formula granules compared with placebo need to be considered clinically.

Abstract
Background Dispensing granules have been developed for about 20 years. However, whether they are as effective as the traditional decoction kept unclear. This systematic review and meta-analysis was made to assess the efficacy of dispensing granules compared with traditional decoction. Methods We searched four databases since their inception to 9th September in 2016. Two authors independently identified trials, extracted data and assessed risk of bias with Cochrane Reviewer's Handbook 5.0. We conducted meta-analysis with RevMan 5.1.0 software for eligible and appropriate trials. Results In the end, 7,035 participants from 51 randomized controlled trials (RCTs) which compared dispensing granules with traditional decoction were included in this systematic review. There were 33 different kinds of diseases for investigation, of which 8 RCTs observed common cold, 4 RCTs observed migraine. For rheumatoid arthritis, insomnia and hypertension, there were 3 RCTs reported respectively. The last RCTs reported different kinds of diseases in one or two trials. The majority of trials were in low methodological quality. Thirty-eight (74.5%) RCTs showed that the efficacy of dispensing granules were similar with traditional decoction, 6 (11.8%) RCTs reported that the therapeutic efficacy of dispensing granules were significantly better than traditional decoction. We conducted meta-analysis for 4 trials investigating patients with migraine. The results showed that dispensing granules reduced headache frequency by about 1.03 attacks per month as compared to traditional decoction. No evidence was found in terms of migraine intensity and duration. Conclusions The low quality of RCTs and conflicting results made it difficult to draw a definite conclusion. In the future, it needs much more evidence to explore the efficacy and safety of dispensing granules. N-of-1 trials and fuzzy comprehensive evaluation methods may be better choices for assessing the efficacy of them than RCTs.

[PMID: 28878815 PMCID: PMC5584346 DOI: 10.1186/s13020-017-0146-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2017] [Accepted: 08/30/2017] [Indexed: 01/01/2023] Open
Abstract
Background The vast majority of stroke burden is attributable to its modifiable risk factors. This paper aimed to systematically summarise the evidence of Chinese herbal medicine (CHM) interventions on stroke modifiable risk factors for stroke prevention. Methods A literature search was conducted via the MEDLINE, CINAHL/EBSCO, SCOPUS, and Cochrane Database from 1996 to 2016. Randomised controlled trials or cross-over studies were included. Risk of bias was assessed according to the Cochrane Risk of Bias tool. Results A total of 46 trials (6895 participants) were identified regarding the use of CHM interventions in the management of stroke risk factors, including 12 trials for hypertension, 10 trials for diabetes, eight trials for hyperlipidemia, seven trials for impaired glucose tolerance, three trials for obesity, and six trials for combined risk factors. Amongst the included trials with diverse study design, an intervention of CHM as a supplement to biomedicine and/or a lifestyle intervention was found to be more effective in lowering blood pressure, decreasing blood glucose level, helping impaired glucose tolerance reverse to normal, and/or reducing body weight compared to CHM monotherapy. While no trial reported deaths amongst the CHM groups, some papers do report moderate adverse effects associated with CHM use. However, the findings of such beneficial effects of CHM should be interpreted with caution due to the heterogeneous set of complex CHM studied, the various control interventions employed, the use of different participants’ inclusion criteria, and low methodological quality across the published studies. The risk of bias of trials identified was largely unclear in the domains of selection bias and detection bias across the included studies. Conclusion This study showed substantial evidence of varied CHM interventions improving the stroke modifiable risk factors. More rigorous research examining the use of CHM products for sole or multiple major stroke risk factors are warranted.

Abstract
Cardiovascular diseases are the principal cause of death worldwide. The potentially serious adverse effects of therapeutic drugs lead to growing awareness of the role of Chinese herbal medicine in the treatment of cardiovascular diseases. Chinese herbal medicine has been widely used in many countries especially in China from antiquity; however, the mechanisms by which herbal medicine acts in the prevention and treatment of cardiovascular diseases are far from clear. In this review, we briefly describe the characteristics of Chinese herbal medicine by comparing with western medicine. Then we summarize the formulae and herbs/natural products applied in the clinic and animal studies being sorted according to the specific cardiovascular diseases. Most importantly, we elaborate the existing investigations into mechanisms by which herbal compounds act at the cellular levels, including vascular smooth muscle cells, endothelial cells, cardiomyocytes and immune cells. Future research should focus on well-designed clinic trial, in-depth mechanic study, investigations on side effects of herbs and drug interactions. Studies on developing new agents with effectiveness and safety from traditional Chinese medicine is a promising way for prevention and treatment of patients with cardiovascular diseases.

Abstract
AIMS The aim was to perform a systematic review of the efficacy of traditional Chinese medicines (TCM) in cardiovascular disease. METHODS Electronic databases were searched up to 11 November 2015 for all randomized-controlled trials evaluating the effect of TCM in hypertension, ischaemic stroke, heart failure, coronary heart disease and type 2 diabetes mellitus. Pooled odds ratios (ORs) were calculated using a fixed-effects model. RESULTS Four hypertension studies were eligible for statistical analysis and included 133 patients receiving TCM and 130 control patients. There were significant reductions in systolic blood pressure in patients receiving TCM, comparable to results achieved with pharmaceutical medicines. An OR of 3.781 (95% confidence interval 2.392, 5.977; P = 0.000) was observed for the anti-hypertensive effect of TCM. Significant heterogeneity was present (P = 0.011), with a tendency towards publication bias that did not reach significance (P = 0.05275). Outcome measures for other cardiovascular diseases were inconsistent. CONCLUSIONS Certain TCM compounds appear to have significant anti-hypertensive effects, and although some are associated in some studies with improved outcomes in coronary heart disease, heart failure and type 2 diabetes mellitus, the data are inconsistent and will require large-scale randomized-controlled trials to allow full evaluation of any potential therapeutic benefit in these areas.
