Salvia miltiorrhiza Injection on Pulmonary Heart Disease: A Systematic Review and Meta-Analysis

A systematic review and meta-analysis on sodium tanshinone IIA sulfonate injection for the adjunctive therapy of pulmonary heart disease

AIMS

Sodium tanshinone IIA sulfonate (STS) injection has been widely used as adjunctive therapy for pulmonary heart disease (PHD) in China. Nevertheless, the efficacy of STS injection has not been systematically evaluated so far. Hence, the efficacy of STS injection as adjunctive therapy for PHD was explored in this study.

METHODS

Randomized controlled trials (RCTs) were screened from China Science and Technology Journal Database, China National Knowledge Infrastructure, Wanfang Database, PubMed, Sino-Med, Google Scholar, Medline, Chinese Biomedical Literature Database, Cochrane Library, Embase and Chinese Science Citation Database until 20 January 2024. Literature searching, data collection and quality assessment were independently performed by two investigators. The extracted data was analyzed with RevMan 5.4 and STATA 14.0. Basing on the methodological quality, dosage of STS injection, control group measures and intervention time, sensitivity analysis and subgroup analysis were performed.

RESULTS

19 RCTs with 1739 patients were included in this study. Results showed that as adjunctive therapy, STS injection combined with Western medicine showed better therapeutic efficacy than Western medicine alone for PHD by increasing the clinical effective rate (RR = 1.22; 95% CI, 1.17 to 1.27; p < 0.001), partial pressure of oxygen (MD = 10.16; 95% CI, 5.07 to 15.24; p < 0.001), left ventricular ejection fraction (MD = 8.66; 95% CI, 6.14 to 11.18; p < 0.001) and stroke volume (MD = 13.10; 95% CI, 11.83 to 14.38; p < 0.001), meanwhile decreasing the low shear blood viscosity (MD = -1.16; 95% CI, -1.57 to -0.74; p < 0.001), high shear blood viscosity (MD = -0.64; 95% CI, -0.86 to -0.42; p < 0.001), plasma viscosity (MD = -0.23; 95% CI, -0.30 to -0.17; p < 0.001), hematokrit (MD = -8.52; 95% CI, -11.06 to -5.98; p < 0.001), fibrinogen (MD = -0.62; 95% CI, -0.87 to -0.37; p < 0.001) and partial pressure of carbon dioxide (MD = -8.56; 95% CI, -12.09 to -5.02; p < 0.001).

CONCLUSION

STS injection as adjunctive therapy seemed to be more effective than Western medicine alone for PHD. However, due to low quality of the included RCTs, more well-designed RCTs were necessary to verify the efficacy of STS injection.

Modulation of the vitamin D receptor by traditional Chinese medicines and bioactive compounds: potential therapeutic applications in VDR-dependent diseases

The Vitamin D receptor (VDR) is a crucial nuclear receptor that plays a vital role in various physiological functions. To a larger extent, the genomic effects of VDR maintain general wellbeing, and its modulation holds implications for multiple diseases. Current evidence regarding using vitamin D or its synthetic analogs to treat non-communicable diseases is insufficient, though observational studies suggest potential benefits. Traditional Chinese medicines (TCMs) and bioactive compounds derived from natural sources have garnered increasing attention. Interestingly, TCM formulae and TCM-derived bioactive compounds have shown promise in modulating VDR activities. This review explores the intriguing potential of TCM and bioactive compounds in modulating VDR activity. We first emphasize the latest information on the genetic expression, function, and structure of VDR, providing a comprehensive understanding of this crucial receptor. Following this, we review several TCM formulae and herbs known to influence VDR alongside the mechanisms underpinning their action. Similarly, we also discuss TCM-based bioactive compounds that target VDR, offering insights into their roles and modes of action.

Investigation of the efficacy and pharmacological mechanism of Danhong injections for treating chronic obstructive pulmonary disease: A PRISMA-compliant meta-analysis and network pharmacology analysis

BACKGROUND

Accumulating evidence supported the clinical efficacy of Danhong injection (DHI) on chronic obstructive pulmonary disease (COPD). It is urgent to summarize the effects of DHI on various outcomes in COPD patients and to elucidate the molecular mechanisms of DHI in treating COPD.

METHODS

Eligible studies were retrieved from 6 databases including China national knowledge infrastructure, Wangfang, VIP, web of science, PubMed, and Embase. The heterogeneity across studies was tested using the I2 statistic and the quality of studies was assessed. The pooled evaluation of outcomes was calculated using a fix- or random-effect model according to the heterogeneity. The underlying mechanism of DHI in treating COPD was analyzed using network pharmacology.

RESULTS

A total of 34 eligible studies with a general medium quality were included in the meta-analysis. The pooled data showed that DHI intervention significantly increased clinical efficacy as compared to routine treatment. Meanwhile, our data also revealed that the addition of DHI markedly improved hemorheological indicators, lung function index, arterial blood gas index, and as well as blood coagulation functions. However, the current meta-analysis lacked sufficient data to support the significant effect of DHI on prothrombin time and activated partial thromboplastin time. Network pharmacology found 59 candidate targets of DHI in treating COPD, and enrichment analysis found these targets were associated with lymphocyte proliferation and activation, glucocorticoid receptor signaling, TREM1 signaling, IL-12 signaling and production in macrophages, and aryl hydrocarbon receptor signaling. Multiple core targets including AKT1, TNF, and IL1B, etc. Were identified and might play an important role in the action of DHI against COPD.

CONCLUSION

Taken together, this study suggested that DHI could ameliorate hemorheological indicators, lung function, arterial blood gas, and as well as coagulation functions of COPD patients and elucidate the underlying mechanism of DHI against COPD.

Treatment of Chronic Pulmonary Heart Disease with Traditional Chinese Medicine: A Protocol for the Development of a Core Outcome Set (COS-TCM-CPHD)

Background

Treatment of chronic pulmonary heart disease (CPHD), a common disease, has over recent years been studied using traditional Chinese medicine (TCM) due to many high-profile benefits. These can be evaluated by the measurement and analysis of related outcomes. Because of selective reporting bias and the heterogeneity of study outcomes, it is not possible to combine similar studies in a meta-analysis. Consequently, not only does the low quality of original studies fails to support evidence-based decision-making, but also the value of those clinical studies cannot be evaluated. To solve these problems, the development of a core outcome set for traditional Chinese medicines for the treatment of chronic pulmonary heart disease (COS-TCM-CPHD) is required.

Methods

The development is conducted in five steps: (1) a library of outcomes through systematic review, the retrieval of libraries from two clinical trials registries, and semistructured interviews is established; (2) following data extraction and analysis of the library of outcomes, each outcome can be classified into seven outcome domains, including TCM disease, symptoms/signs, physical and chemical testing, quality of life, long-term prognosis, economic evaluation, and adverse events to form a preliminary list of outcomes; (3) stakeholder groups for participation are selected; (4) stakeholder groups are invited to participate in two rounds of Delphi surveys to score outcomes and provide additional outcomes; (5) a consensus meeting is organized to produce the final COS-TCM-CPHD. Discussion. The protocol is consistent with the guidelines defined by the Core Outcome Set-STAndardised Protocol (COS-STAP) statement and formulated with reference to Core Outcome Set-STAndards for development (COS-STAD). The COS-TCM-CPHD will improve the consistency of study reports and reduce publication bias, thereby improving the quality of TCM clinical trials and decision-making for evidence-based medicine. The study has been registered on the COMET website (http://www.comet-initiative.org/Studies/Details/1677).

Ginkgo leaf extract and dipyridamole injection for chronic cor pulmonale: a PRISMA-compliant meta-analysis of randomized controlled trials

Ginkgo leaf extract and dipyridamole injection (GLED), a kind of Chinese herbal medicine preparation, has been considered as a promising supplementary treatment for chronic cor pulmonale (CCP). Although an analysis of the published literature has been performed, the exact effects and safety of GLED have yet to be systematically investigated. Therefore, a wide-ranging systematic search of electronic databases from which to draw conclusions was conducted. All randomized controlled trials concerning the GLED plus conventional treatments for CCP were selected in the present study. Main outcomes were treatment efficacy, blood gas and hemorrheology indexes, and adverse events. Data from 28 trials with 2457 CCP patients were analyzed. The results indicated that, compared with conventional treatments alone, the combination of conventional treatments with GLED obviously improved the markedly effective rate (RR = 1.44, 95% CI = 1.31–1.58, P < 0.00001) and total effective rate (RR = 1.28, 95% CI = 1.18–1.38, P < 0.00001). Moreover, the hemorrheology (PaO₂, P < 0.00001; PaCO₂, P < 0.00001; SaO₂, P < 0.00001; pH value, P = 0.05) and blood gas indexes (PV, WBHSV, WBMSV, WBLSV, hematocrit and FBG, P < 0.01) of CCP patients were also significantly ameliorated after the combined therapy. The frequency of adverse events did not differ significantly between the two groups (P > 0.05). In summary, evidence from the meta-analysis suggested that the combination of conventional treatments and GLED appeared to be effective and relatively safe for CCP. Therefore, GLED mediated therapy could be recommended as an adjuvant treatment for CCP.

Clinical efficacy and safety of Chinese herbal medicine versus placebo for the treatment of chronic obstructive pulmonary disease: A systematic review and meta-analysis

OBJECTIVE

Randomized clinical trials and published meta-analyses assessing the clinical effectiveness of Chinese herbal medicine (CHM) on the treatment of stable chronic obstructive pulmonary disease (COPD) yielded inconsistent results in terms of disease outcomes, in which the design of placebo-controlled studies can contribute to the heterogeneity. This study aimed to evaluate the efficacy and safety of CHM compared to placebo on the treatment of stable COPD, to provide robust evidence for the use of CHM in COPD.

METHODS

Nine electronic databases were searched from inception to October 1, 2019 to identify placebo controlled randomized trials of CHM for the treatment of stable COPD and studies in English or Chinese were included. The primary outcomes were symptom score (CAT score), quality of life (SGRQ) and frequency of acute exacerbations. The secondary outcomes included lung function, clinical total effective rate and adverse events. The selection of studies, data extraction and coding and assessment of risk of bias of the included studies were conducted by two reviewers independently. Mean difference (MD) was used to analyze continuous variable and relative risk ratio (RR) for dichotomous data.

RESULTS

A total of eleven studies involving 1223 patients were included. While maintaining routine western pharmacotherapies (WP), CHM had significant advantage over the treatment of placebo in improving CAT score (MD -3.93; 95 %CI -6.01 to -1.85) and SGRQ score (MD -6.20; 95 %CI -10.13 to -2.28), reducing the frequency of acute exacerbations (MD -0.78; 95 %CI -1.40 to -0.16) and improving clinical effective rate (RR 1.29; 95 %CI 1.14 to 1.45), but had no significant effect on improving FEV₁%pred (MD 8.18; 95 %CI -4.22 to 20.58). High heterogeneity was found for the changes in exacerbation frequency and FEV₁%pred. No serious adverse events related to CHM were reported.

CONCLUSIONS

This meta-analysis of placebo-controlled RCTs demonstrated that the use of CHM in addition to WP could alleviate clinical symptoms, improve quality of life and clinical efficiency and reduce the frequency of exacerbations, which could be an alternative approach for treatment adjustment of COPD. CHM was a relatively safe treatment. These findings need to be verified in future with high-quality clinical trials.

Pseudo-allergic compounds screened from Shengmai injection by using high-expression Mas-related G protein-coupled receptor X2 cell membrane chromatography online coupled with liquid chromatography and mass spectrometry

Adverse drug reactions of traditional Chinese medicine injection mainly manifested as pseudo-allergic reactions. In the present study, ginsenoside Rd, Ro, and Rg₃ were identified as pseudo-allergic components in Shengmai injection by a high-expression Mas-related G protein-coupled receptor X2 cell membrane chromatography coupled online with high-performance liquid chromatography and mass spectrometry. Their pseudo-allergic activities were evaluated by in vitro and in vivo assay. The three compounds were further found to induce pseudo-allergic reaction through Mas-related G protein-coupled receptor X2. Therefore, we concluded that ginsenoside Rd, Ro and Rg₃ may be potential allergens that cause pseudo-allergic reactions. This study might be helpful for the safe use of Shengmai injection.

BACKGROUND

Chinese herbal medicine injections (CHMIs) are frequently used for various refractory diseases including chronic pulmonary heart disease (CPHD). However, due to the diversity of CHMIs treatments, its relative effectiveness and safety remain unclear. In our study, Bayesian network meta-analysis will be used to identify differences in efficacy and safety between diverse CHMI for CPHD.

METHODS

Relevant randomized controlled trials (RCTs) and prospective controlled clinical trials published in PubMed, Google Scholar, Excerpt Medica Database, Medline, Cochrane Library, Web of Science, China Scientific Journal Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and Wanfang Database will be systematic searched to identify eligible studies from their establishment to December 2020. The methodological qualities, including the risk of bias, will be evaluated using the Cochrane risk of bias assessment tool. Stata14.2 and WinBUGS 1.4.3 software were used for data synthesis. The evidentiary grade of the results will be also evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

The results of this study will be published in a peer-reviewed journal, and provide reliable evidence for different CHMIs on CPHD.

CONCLUSIONS

The findings will provide reference for evaluating the efficacy and safety of different CHMIs for CPHD, and provide a helpful evidence for clinicians to formulate the best adjuvant treatment strategy for CPHD patients.

The Effects of Traditional Chinese Medicine as an Auxiliary Treatment for COVID-19: A Systematic Review and Meta-Analysis

Background: Coronavirus disease 2019 (COVID-19) has become a pandemic with no specific and widely accepted effective drug or vaccine. However, studies have shown that Traditional Chinese Medicine (TCM) may play a significant role as an auxiliary treatment for COVID-19. Objective: This study aimed to assess the effects of TCM as an auxiliary treatment for COVID-19 through a systematic review of randomized-controlled trials (RCTs). Methods: Four English and three Chinese language databases were searched from December 1, 2019, to June 30, 2020. RCTs comparing TCM in combination with Western medicine (WM) with the same WM therapies alone for confirmed COVID-19 patients were included. The outcome measures were cure rate, lowering of body temperature, cough relief, improvement in chest computed tomography (CT) images, deterioration of condition, and adverse effects. Methodological quality was assessed using the Cochrane risk-of-bias tool. A series of meta-analyses were conducted for selected outcomes using RevMan 5.3 software. The quality of evidence was appraised using the grading of recommendation, assessment, development, and evaluation (GRADE) recommendations. Results: Ten RCTs with a total of 1,285 patients were included. Compared with WM alone in treating COVID-19, WM with auxiliary treatment by TCM appears to have increased the cure rate (risk ratio [RR] 1.15 [95% confidence interval (CI) 1.04-1.26]), relieved cough (RR 1.32 [95% CI 1.15-1.52]), improved chest CT images (RR 1.23 [95% CI 1.11-1.37]), and reduced the number of cases transitioning from a moderate to severe condition (RR 0.58 [95% CI 0.43-0.77]). The authors are uncertain whether TCM combined WM has effects on fever normalization (RR 1.10 [95% CI 0.94-1.29]) or adverse effects (RR 0.81 (95% CI 0.42-1.57]). Although they evaluated the certainty of evidence for lowering body temperature and adverse effects as very low, and low for cure rate, certainty was evaluated as moderate for improvement in chest CT images, cough relief, and deterioration of condition. Conclusion: TCM may be an effective auxiliary treatment for COVID-19 patients, which is likely to help improve the main symptoms and reduce disease progression. However, due to the limited number of studies and apparent heterogeneity among them, a more definitive conclusion on the effect of TCM on lowering body temperature and adverse effects cannot be drawn at this time.

Salvia miltiorrhiza in Treating Cardiovascular Diseases: A Review on Its Pharmacological and Clinical Applications

Bioactive chemical constitutes from the root of Salvia miltiorrhiza classified in two major groups, viz., liposoluble tanshinones and water-soluble phenolics. Tanshinone IIA is a major lipid-soluble compound having promising health benefits. The in vivo and in vitro studies showed that the tanshinone IIA and salvianolate have a wide range of cardiovascular and other pharmacological effects, including antioxidative, anti-inflammatory, endothelial protective, myocardial protective, anticoagulation, vasodilation, and anti-atherosclerosis, as well as significantly help to reduce proliferation and migration of vascular smooth muscle cells. In addition, some of the clinical studies reported that the S. miltiorrhiza preparations in combination with Western medicine were more effective for treatment of various cardiovascular diseases including angina pectoris, myocardial infarction, hypertension, hyperlipidemia, and pulmonary heart diseases. In this review, we demonstrated the potential applications of S. miltiorrhiza, including pharmacological effects of salvianolate, tanshinone IIA, and its water-soluble derivative, like sodium tanshinone IIA sulfonate. Moreover, we also provided details about the clinical applications of S. miltiorrhiza preparations in controlling the cardiovascular diseases.

CONCLUSION

The study will confirm whether Chinese oral herbal paste is an effective and safe intervention for the prevention and treatment of stable COPD.

Post-marketing safety surveillance and re-evaluation of Xueshuantong injection

BACKGROUND

Traditional Chinese medicine injections (TCMIs) have been widely used to treat severe and acute diseases due to their high bioavailability, accurate curative effect, and rapid effect. However, incidence rates of adverse drug reactions (ADRs) of TCMIs have also increased in recent years. Xueshuantong injection (XSTI) is a commonly-used TCMI comprised of Panax notoginseng total sapiens for the treatment of stroke hemiplegia, chest pain, and central retinal vein occlusion. Its safety remains uncelar. Therefore, post-marketing safety of XSTI was studied in this research.

METHODS

In present study, post-marketing safety surveillance and re-evaluation of XSTI were reported. Thirty thousand eight hundred eighty-four patients in 33 hospitals from 7 provinces participated in this study. Incidence rate, most common clinical manifestations, types, severity, occurrence time, and disposal of ADRs were calculated.

RESULTS

Incidence rate of ADR of XSTI was 4.14‰ and the most common clinical manifestations were skin and its appendages damage. Type A accounts for 95.49% of ADRs of XSTI and most of them (41.41%) were occurred within 24 h after receiving XSTI treatment. Severities of most ADRs of XSTI were moderate reactions (86.72%). Main disposition of ADRs of XSTI was drug withdrawal and symptomatic treatment (54.69%).

CONCLUSIONS

Our data provide basis for improvement of instructions of XSTI and clinical safety of XSTI. Post-marketing surveillance of TCMIs in this study is a powerful tool to identify types and manifestations of ADRs to improve safety and effectiveness of drugs in clinical applications.

Therapeutic effects of Salvia miltiorrhiza injection combined with telmisartan in patients with diabetic nephropathy by influencing collagen IV and fibronectin: A case-control study

Involvement of collagen IV (ColIV) and fibronectin (FN) in the occurrence and development of diabetic nephropathy (DN) and the effects of telmisartan and Salvia miltiorrhiza injection in the treatment of the patients were investigated. Two hundred and fifty-eight patients with stage IV DN were selected as the case group, and another 110 normal healthy subjects were incorporated as the control group. Involved patients were subdivided into different groups according to different treatment therapies; patients in the telmisartan group (T group) were given oral telmisartan; patients in the Salvia miltiorrhiza injection + telmisartan (S + T group) were administered with Salvia miltiorrhiza injection combined with telmisartan treatment, and there was a group of patients who received no intervention as the placebo group. After intervention, levels of glycemic indexes and renal damage indexes indicated downwards trends both in the T group and the S + T group when compared to the placebo group; besides, levels in the S + T group were much lower than those in the T group (all P<0.05). Additionally, in comparison among the above three intervention groups, differences in the fasting blood glucose, 2 h post-prandial blood glucose, glycosylated hemoglobin, blood urea nitrogen, serum creatinine and urinary albumin excretion rate were significant after treatment (all P<0.05). Further, before intervention, both Co1IV and FN in the urine were increased in the case group compared to the control group (all P<0.05). After intervention, both levels were apparently decreased. There were remarkable differences of Co1IV and FN levels in the urine when compared among three different intervention groups after treatment (P<0.05). Increased ColIV and FN levels may be partially responsible for the development of DN. Salvia miltiorrhiza injection with telmisartan have beneficial synergistic effects for DN patients through attenuating the increase in ColIV and FN, reversing hyperglycemia state and postponing ultrastructure changes of glomerular basement membrane.

Preparation and Quality Evaluation of Salvianolic Acids and Tanshinones Dry Powder Inhalation

Salvianolic acids and tanshinones both exhibit efficacy in treating idiopathic pulmonary fibrosis (IPF), but their formulation limits their clinical use. This study aimed to prepare the salvianolic acids and tanshinones dry powder for inhalation (SPI) to achieve pulmonary delivery for the treatment of IPF. The variable quantities of salvianolic acids and tanshinones composite powder were optimized using the central composite design-response surface method. Different carriers with various drug-carrier ratios were optimized to prepare SPI. The final optimized formulation of SPI was as follows: InhaLac 230^® was selected as the carrier with drug:carrier = 1:6, and the milled lactose InhaLac 400^® was added at 5%. The developed SPI characterized with an angle of repose 52.46 ± 1.04°, Carr's index of 34.00 ± 0.50% and showed high lung deposition in vitro, indicating the potential of pulmonary delivery for the treatment of IPF.

Management of IFN-beta-induced flu-like symptoms with Chinese herbal medicine in a patient with multiple sclerosis: A case report

OBJECTIVE

The purpose of this case report was to elucidate how Chinese herbal medicine (CHM) was used safely in this patient undergoing interferon beta (IFNβ-1a) treatment and was associated with reduction in the side effects the patient had experienced when using IFNβ-1a treatment alone.

CLINICAL FEATURES AND OUTCOME

A 30-year-old man was diagnosed with MS in December 2014. For two years, he suffered from severe flu-like symptoms as side effects of IFNβ-1a treatment. He subsequently received treatment with Chinese herbal medicine. During a two-month period of treatment with CHM, the patient responded well, with most of the symptoms induced by IFNβ-1a ameliorated. The fever subsided. Incidence rates of dizziness and headaches were reduced. The health condition compared to the prior year increased by 50%. According to CCMQ and SF-36 assessments, CHM had the beneficial effects of recovering the yin-yang balance, harmonizing the qi, and regulating the blood state; essentially, improving the patient's comfort level and quality of life.

CONCLUSIONS

IFNβ-1a injections will damage qi and cause blood stasis in MS patients, thereby causing various side effects and weakening the body's immune system. Bu-Zhong-Yi-Qi-Tang, associated with Salvia miltiorrhiza, Ligusticum chuanxiong, Angelica dahurica and Polygonum multiflorum Thunb., is an effective prescription to ameliorate such symptoms and signs in patients with MS.

Reversal of doxorubicin-resistance by Salvia miltiorrhiza ligustrazine in the SHG44/doxorubicin glioma drug-resistant cell line

The multidrug resistance of glioma impedes chemo-radiotherapy and leads to adverse outcomes. In the present study, the doxorubicin (DOX)-resistant glioma SHG44/DOX cell line was established to investigate the effects and mechanisms of Salvia miltiorrhiza ligustrazine (SML), a traditional Chinese medicine, on the reversal of DOX-resistance. The SHG44/DOX cells grew continually in 0.1 µg/ml DOX and expressed increased levels of mRNA of multidrug resistance genes [multidrug resistance 1 (MDR1), multidrug resistance-associated protein 1 (MRP1) and lung resistance protein (LRP)] compared with the parental SHG44 cells. Treatment with DOX plus SML suppressed proliferation and promoted early apoptotic rates in SHG44/DOX cells, although treatment with DOX alone failed to inhibit SHG44/DOX cells. In addition, the levels of MDR1, MRP1 and LRP were downregulated by this traditional Chinese medicine, coupled with increased intracellular DOX concentrations. Tumor-bearing nude mouse models were also established using SHG44/DOX cells, and it was demonstrated that the tumor volumes and proliferation indexes were lower in the DOX plus SML group compared with the DOX alone group. The present data demonstrated that treatment with SML was able to reverse the DOX resistance of SHG44/DOX cells, which suggests that SML may be a potential adjuvant agent for glioma chemo-radiotherapy.

Traditional Chinese Medicine, Food Therapy, and Hypertension Control: A Narrative Review of Chinese Literature

Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the “hot” and “cold” nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control. Based on a statistical analysis of antihypertensive foods recommended in 20 books on the application of food therapy for hypertension control, the 38 most frequently recommended are celery, tomato, banana, hawthorn, garlic, onion, seaweed, apple, corn, green beans, persimmon, laver, kiwi, watermelon, eggplant, carrots, mushroom, peanut, soy products, sea cucumber, buckwheat, garland chrysanthemum, spinach, honey, dairy products, vinegar, black fungus, jellyfish, green onion, shepherd's purse, soybean, potato, pear, winter melon, bitter melon, oat, pea, and tea. Food therapy emphasizes the therapeutic effects of food, considering its nature, taste, and function on human balanced health, which leads to optimal blood pressure control. Current literature suggests that food therapy is effective in blood pressure control and can be incorporated into blood pressure self-management in the Chinese population.

Roles of Reactive Oxygen Species in Anticancer Therapy with Salvia miltiorrhiza Bunge

Cancer is a leading cause of death worldwide. We aim to provide a systematic review about the roles of reactive oxygen species (ROS) in anticancer therapy with Salvia miltiorrhiza Bunge (Danshen). Danshen, including its lipophilic and hydrophilic constituents, is potentially beneficial for treating various cancers. The mechanisms of ROS-related anticancer effects of Danshen vary depending on the specific type of cancer cells involved. Danshen may enhance TNF-α-induced apoptosis, upregulate caspase-3, caspase-8, caspase-9, endoplasmic reticulum stress, P21, P53, Bax/Bcl-2, DR5, and AMP-activated protein kinase, or activate the p38/JNK, mitogen-activated protein kinase, and FasL signaling pathways. Conversely, Danshen may downregulate human telomerase reverse transcriptase mRNA, telomerase, survivin, vascular endothelial growth factor/vascular endothelial growth factor receptor 2, CD31, NF-κB, Erk1/2, matrix metalloproteinases, microtubule assembly, and receptor tyrosine kinases including epidermal growth factor receptors, HER2, and P-glycoprotein and inhibit the PI3K/Akt/mTOR or estrogen receptor signaling pathways. Therefore, Danshen may inhibit cancer cells proliferation through antioxidation on tumor initiation and induce apoptosis or autophagy through ROS generation on tumor progression, tumor promotion, and tumor metastasis.

Carthamus tinctorius L. is a multifunctional cash crop. Its flowers and seeds are extensively used in traditional herbal medicine in China, Korea, Japan, and other Asian countries, for treating various ailments such as gynecological, cardiovascular, and cerebrovascular diseases as well as blood stasis and osteoporosis. More than 100 compounds have been isolated and identified from C. tinctorius. Flavonoids and alkaloids, especially the quinochalcone c-glycoside hydroxysafflor yellow A, N-(p-Coumaroyl)serotonin, and N-feruloylserotonin, are responsible for most of the pharmacological activities of C. tinctorius. In this paper, comprehensive and up-to-date information on the phytochemistry and pharmacology of C. tinctorius is presented. This information will be helpful for further explorations of the therapeutic potential of C. tinctorius and may provide future research opportunities.

A systematic review of integrated traditional Chinese and Western medicine for managing irritable bowel syndrome

Traditional Chinese medicine (TCM) has been commonly used by Chinese practitioners to treat irritable bowel syndrome (IBS). However, the effectiveness of combining TCM with Western medicine in managing IBS has not been evaluated systematically. In this study, we evaluated the clinical effectiveness of combining TCM and Western medicine in the treatment of IBS via meta-analyses. We reviewed 72 eligible randomized controlled trials from January 2009 to December 2013 investigating the effectiveness of integrated TCM and Western medicine in the management of IBS. In the meta-analyses, the relative risks (RRs) and 95% confidence interval (95%CI) were calculated using raw data from each study, and low heterogeneity was detected. When compared to the Western medicine treatment alone, our result showed TCM combined with Western interventions significantly improved IBS global symptoms (RR, 1.21; 95%CI: 1.18-1.24). Additionally, there was no significant difference in therapeutic effects of the integrated approach in the meta-analyses involving the various IBS subtypes. Likewise, both Chinese proprietary herbal medicine plus conventional treatment and compound herbal preparations plus conventional treatment showed similar and statistically significant effects on global improvement compared with western treatment alone, with RRs of 1.22 (95%CI: 1.14-1.30) and 1.22 (95%CI: 1.18-1.27), respectively. These results demonstrated that treating IBS with integrated traditional Chinese and Western medicines showed better effectiveness than conventional Western medicine alone. Although due to the quality of the included studies, our results might possess a high risk of bias. TCM, particularly Chinese proprietary medicine, with the benefits of low-cost, easy to use, and good palatability, would be an attractive option to be used in conjunction with conventional Western medicine to manage IBS patients.
