Shengjie Tongyu Decoction Regulates Cardiomyocyte Autophagy Through Modulating ROS-PI3K/Akt/mTOR Axis by LncRNA H19 in Diabetic Cardiomyopathy.

Context: Diabetic cardiomyopathy (DCM) is particularly dangerous in diabetes mellitus (DM). The Shengjie Tongyu decoction (SJTYD) is a well-known, traditional Chinese medicinal formulation that practitioners use to treat myocardial diseases in China; however, its role in DCM remain unclear. Objective: The study intended to investigate: (1) SJTYD's role in the treatment of DCM and its underlying mechanisms, (2) the association of autophagy with DCM, and (3) the involvement of mammalian target of rapamycin (mTOR) signaling in the regulation of DCM. Design: The research team performed an animal study. Setting: The study took place in the Department of Endocrinology in the No. 2 ward-Traditional and Complementary Medicine(TCM) of the China-Japan Friendship Hospital in Beijing, China. Animals: The animals were 60 C57/BL6 mice weighing 200-250 g. Intervention: To determine the role of SJTYD in treating DCM, the research team established a mouse model of DM using streptozotocin (STZ). The team randomly divided the mice into three groups with 20 mice each: (1) a negative control group, which didn't receive injections of STZ or treatment with SJTYD; (2) a model group, the Model group, which received injections of STZ but didn't receive treatment with SJTYD; and (3) an SJTYD group, which received injections of STZ and treatment with SJTYD. Outcome Measures: The research team: (1) conducted a differential analysis to identify the differentially expressed genes; (2) performed deep sequencing of the long noncoding RNAs (lncRNAs) expressed in cardiomyocytes from the control, Model, and SJTYD groups ; (3) performed a bioinformatics analysis; (4) used the ultrasonic and pathological, transmission electron microscopy (TEM) test as well as a Western blot to evaluate cardiac function, myocardial-injury areas, and autophagy in vivo; (5) transfected primary cardiomyocytes treated them with lncRNA H19 and SJTY 3-MA to establish SJTYD subgroups in which the H19 protected against DCM and the 3-MA inhibited autophagy; and (6) carried out immunofluorescence staining and Western blot to test the phosphorylated levels of phosphoinositide 3-kinase (PI3K)/ protein kinase B (AKT)/ mammalian target of rapamycin (mTOR) as well as autophagy levels in vitro. Results: The bioinformatics analysis indicated that SJTYD significantly modulated lncRNA H19 as well as the mTOR pathway. The vevo2100's results indicated the SJTYD reversed the cardiac-dysfunction parameters in DCM. The Masson' staining, TEM, and Western blot demonstrated that the SJTYD could suppress the myocardial-injury areas as well as the numbers of autophagosomes and the expression proteins of autophagy in vivo. The SJTYD promoted the phosphorylated-levels of PI3K, AKT, and mTOR and decreased the levels of autophagy proteins. LC3A-II and Beclin-1; lncRNA H19 amplified the SJTYD's role; and 3-MA reversed those effects, as tested using immunofluorescence and Western blot in primary cardiomyocytes. Conclusions: The SJTYD can protect against diabetic myocardial injury by inhibiting cardiomyocyte autophagy through the activation of lncRNA H19, reactive oxygen species (ROS), and the PI3K/Akt/mTOR signaling pathway. SJTYD may be an effective strategy to ameliorate diabetic myocardial injuries.

Xuesaitong promotes myocardial angiogenesis in myocardial infarction mice by inhibiting MiR-3158-3p targeting Nur77.

This study aims to investigate the regulatory effect of Xuesaitong (XST) and miR-3158-3p on angiogenesis. All mice were randomly assigned into Sham group, Model group, XST group, XST + miR-3158-3P-overexpression (miRNA-OE) group. XST was found to increase the left ventricular anterior wall thickness at end diastole and end systole (LVAWd and LVAWs), left ventricular internal dimension at end diastole and end systole (LVIDd and LVIDs), fractional shortening (FS), and ejection fraction (EF) and decrease the proportion of fibrotic areas in mice. In contrast to those in Sham group, the protein expressions of Nur77, p-PI3K, HIF-1α, VEGFs, COX-2 in the heart tissues of mice in Model group were elevated and further increased after XST treatment in comparison with those in Model group. Nur77-/- mice were utilized. It was found that XST enhanced cell viability through a methyl thiazolyl tetrazolium assay and facilitated angiogenesis in each group, as assessed by a catheter formation assay. Specifically, XST was shown to promote the formation of blood vessels. Moreover, the protein expression levels of Associated proteins in the heart tissues of Nur77-/- mice were dramatically reduced in mice in Model and XST group compared with those in WT mice. Additionally, the above-mentioned protein expressions in the heart tissues of Nur77-/- mice did not change significantly in mice in Model + miRNA-OE + XST group compared with those in WT mice, suggesting that miR-3158-3p can specifically inhibit the expression of Nur77. In conclusion, XST inhibits miR-3158-3p targeting Nur77 to facilitate myocardial angiogenesis in mice with myocardial infarction.

Efficacy and Mechanism of the Jiangtang Tiaozhi Recipe in the Management of Type 2 Diabetes and Dyslipidaemia: A Clinical Trial Protocol.

Background: Type 2 diabetes mellitus (T2DM) complicated with dyslipidaemia is associated with a high risk of cardiovascular diseases. The Jiangtang Tiaozhi (JTTZ) recipe is a Chinese herbal formula that has been used to regulate the blood glucose and lipid levels for many years. Interestingly, a previous study has demonstrated its efficacy; however, the associated mechanism remains unclear. We hypothesised that the therapeutic effect of the JTTZ on patients with T2DM may be mediated by the modulation of metabolites secreted by the gut microbiota. This study aims to examine this mechanism. Methods and analysis: This study is a randomised, positive drug parallel-controlled, open-label clinical trial in patients with T2DM and dyslipidaemia. A total of 96 patients will be recruited and randomly assigned to treatment with JTTZ or metformin for 12 weeks. The primary outcome will be the rates of effectively regulated blood glucose and lipid levels (measured with the levels of glycated haemoglobin, fasting plasma glucose, 2-h plasma glucose, triglyceride, and low-density lipoprotein cholesterol). The secondary outcomes will be the changes in body weight, body mass index, and waist circumference and Traditional Chinese Medicine symptom scores. In addition, 16S rRNA gene sequencing will be performed on the gut microbiota obtained from faeces, and metabolomics analysis will be performed based on blood and gut microbiota samples. Intention-to-treat, per-protocol analysis and safety analysis will be performed. Clinical trial registration number: https://clinicaltrials.gov/ct2/show/NCT04623567.

Xuesaitong injection treating acute myocardial infarction: A systematic review and meta-analysis.

BACKGROUND: Although the incidence of acute myocardial infarction (AMI) is decreasing, the mortality in AMI patients remains substantial. Traditional Chinese medicine has shown its role in the prevention and management of AMI. The purpose of this study is to evaluate the clinical efficacy of Xuesaitong injection (XST) for the treatment of AMI by a meta-analysis. METHODS: A literature search was performed in 5 medical databases up to June 1, 2020. Randomized controlled trials involving XST combined with conventional treatment versus conventional treatment were included. A meta-analysis of clinical efficacy, left ventricular function and other objective parameters was performed to evaluate the effects of XST on AMI. RESULTS: Five randomized controlled trials involving 539 participants were eventually included. Meta-analysis showed that the combination of XST and conventional treatment could achieve significantly better effect on improving clinical efficacy (risk ratio: 1.09 [1.01, 1.17]; P = .04), left ventricular ejection fraction (mean difference [MD]: 3.18 [1.69, 4.67]; P < .0001), hypersensitive C-reactive protein (MD: -2.58 [-5.04, -0.12]; P = .04), interleukin 6 (MD: -26.00 [-38.85, -13.16]; P < .0001), cardiac troponin T (MD: -15.85 [-18.09, -13.61]; P < .00001) and creatine kinase myocardial isoenzyme (MD: -73.06 [-79.74, -66.37]; P < .00001). CONCLUSION: XST combined with conventional treatment can achieve better efficacy on clinical performance and some of the AMI related parameters. However the interpretation of the results should be cautious, due to the relatively low quality of included trials. More rigorously designed, large-scaled, randomized controlled trials are warranted to support its clinical use in the future.

Traditional Chinese medicine for acute coronary syndrome: A meta-analysis of clinical manifestations and objective indicators.

BACKGROUND: Modern clinical trials and experimental researches of traditional Chinese medicine (TCM) have been conducted for decades and provided support for the prevention and treatment of acute coronary syndrome (ACS). However the level of evidence and the proper application of TCM were still barely satisfactory. METHODS: In this study, we divided ACS into 3 different stages, including unstable angina, acute myocardial infarction, and post myocardial infarction. Then we systematically reviewed and meta-analyzed the existing randomized controlled trials on both clinical manifestations and objective indicators, in these 3 aspects. RESULTS: The results indicate that TCM can both improve the clinical manifestations and ameliorate the objective parameters in different courses of ACS, including C-reactive protein in unstable angina, left ventricular ejection fraction in acute myocardial infarction and post myocardial infarction. And the incidence of short-term cardiovascular events are lower in TCM intervention group. Some of the improvements lead to potential long-term benefits. CONCLUSION: TCM treatment is beneficial to different courses of ACS. To acquire more solid and comprehensive evidence of TCM in treating ACS, more rigorously designed randomized controlled trials with longer follow-up duration are warranted.

Therapeutic mechanisms of traditional Chinese medicine to improve metabolic diseases via the gut microbiota.

Metabolic diseases such as obesity, type 2 diabetes mellitus, and hyperlipidemia are associated with the dysfunction of gut microbiota. Traditional Chinese medicines (TCMs) have shown considerable effects in the treatment of metabolic disorders by regulating the gut microbiota. However, the underlying mechanisms are unclear. Studies have shown that TCMs significantly affect glucose and lipid metabolism by modulating the gut microbiota, particularly mucin-degrading bacteria, bacteria with anti-inflammatory properties, lipopolysaccharide- and short-chain fatty acid (SCFA)-producing bacteria, and bacteria with bile-salt hydrolase activity. In this review, we explored potential mechanisms by which TCM improved metabolic disorders via regulating gut microbiota composition and functional structure. In particular, we focused on the protection of the intestinal barrier function, modulation of metabolic endotoxemia and inflammatory responses, regulation of the effects of SCFAs, modulation of the gut-brain axis, and regulation of bile acid metabolism and tryptophan metabolism as therapeutic mechanisms of TCMs in metabolic diseases.

The Effect of Chinese Herbal Medicine Combined With Western Medicine on Vascular Endothelial Function in Patients With Hypertension: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

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.

Bibliometric Analysis of the Results of Cardio-Oncology Research.

OBJECTIVE: To analyze the development of cardio-oncology, summarize the research achievements, and provide proposals for its future research. METHODS: The web of science database was used to search for "cardio-oncology" and "oncocardiology" related articles from the beginning of the database (1970) to April 5, 2019. Excel 2016 and Cytoscape were used to analyze the trend of cardio-oncology research. RESULTS: A total of 356 articles were obtained. The number of articles has grown rapidly in recent years. Cardiac injury caused by tumor therapy was a research hotspot (n = 107). Researchers paid more attention to the prevention and treatment of cardiotoxicity (n = 54). Experimental researches were a small part of all studies (n = 72), mainly focusing on the study of cancer drugs' cardiac injury, test indicators of cardiotoxicity, and preventive drugs. The United States (n = 156.25), Italy (n = 48.5), and Canada (n = 23.5) published the most articles, making a great contribution to the development of cardio-oncology. CONCLUSIONS: Cardio-oncology has been developing rapidly and receiving a large amount of research efforts in recent years. Most articles on cardio-oncology were published by the authors from the United States (44%) and Italy (17%), while other countries need to pay more attention to cardio-oncology. As an independent discipline, cardio-oncology is certainly in need of significant progress, but it has formed a basic framework, which has obtained many leading theories and meaningful achievements in diagnostic criteria, diagnostic methods, prevention and treatment, mechanism research, and influencing factor. Cardiac injury of tumor drugs has always been a research hotspot in this discipline, and there is still a lot of research space. The research about detection methods of cardiotoxicity and preventive drugs is gradually increasing. Basic research lags behind, and many mechanisms are still unclear.

Efficacy and safety assessment of traditional Chinese medicine for metabolic syndrome.

Metabolic syndrome (MetS) is a multifarious metabolic disorder that could severely damage multiple organs. The emergence of MetS has markedly increased medical burden for patients. The treatment of MetS involves multitarget regulation, which is the advantage of traditional Chinese medicine (TCM). Many high-quality studies related to TCM for MetS have been conducted in recent years; however, no overall efficacy analysis has been reported. To evaluate the efficacy and safety of TCM against MetS, we reviewed randomized controlled trials of MetS published in the past decade and then selected and analyzed 16 high-quality articles from over 800 papers. The results showed that TCM might be beneficial in improving body weight as well as in regulating glucose and lipid metabolisms; thus, TCM might be an ideal alternative therapy for MetS management. Treatment safety was also estimated in our analysis. A more elaborately designed and long-term observation of TCM for MetS should be performed in the future.

The effect of Chinese herbal medicine combined with western medicine on vascular endothelial function for patients with hypertension: Protocol for a systematic review and meta-analysis.

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.

Application of Traditional Chinese Medicine in Treatment of Atrial Fibrillation.

Atrial fibrillation (AF) is the most common cardiac arrhythmia, which is related to many cardiac and cerebral vascular diseases, especially stroke. It can therefore increase cardiovascular mortality and all-cause death. The current treatments of AF remain to be western drugs and radiofrequency ablation which are limited by the tolerance of patients, adverse side effects, and high recurrence rate, especially for the elderly. On the contrary, traditional Chinese medicine (TCM) with long history of use involves various treatment methods, including Chinese herbal medicines (CHMs) or bioactive ingredients, Chinese patent medicines, acupuncture, Qigong, and Tai Chi Chuan. With more and more researches reported, the active roles of TCM in AF management have been discovered. Then it is likely that TCM would be effective preventive means and valuable additional remedy for AF. The potential mechanisms further found by numerous experimental studies showed the distinct characteristics of TCM. Some CHMs or bioactive ingredients are atrial-selective, while others are multichannel and multifunctional. Therefore, in this review we summarized the treatment strategies reported in TCM, with the purpose of providing novel ideas and directions for AF management.

Modern researches on Blood Stasis syndrome 1989-2015: A bibliometric analysis.

BACKGROUND: Blood Stasis syndrome (BSS) is one of the major syndromes in Traditional East Asia medicine (TEAM). Modern research of BSS began in the late1980s. METHODS: We searched in PubMed for BSS-related articles published between 1989 and 2015. The publication information, study contents, and bibliometric indicators were documented and analyzed. RESULTS: Most of the BSS-related studies were conducted by Chinese researchers in China. The number of publications on BSS-related increased rapidly in recent years, so did the quality of them. The disease diversity of BSS-related studies increased along with the number of publications. Yet the academic influence of them remained on average low; further, the diagnostic criteria of BSS were not uniform. CONCLUSIONS: BSS-related studies have increased in quantity and quality, but there are limitations to them which require improvement in research productivity and academic influence.

Identification of more objective biomarkers for Blood-Stasis syndrome diagnosis.

BACKGROUND: Blood-stasis syndrome (BSS) is one of the Traditional Chinese medicine (TCM) syndrome differentiations that are commonly seen in stroke and ischemic heart diseases; however, the BSS differentiation criterion is not standardized. More objective biomarkers for BSS diagnosis are needed. METHODS: Acute ischemic stroke (AIS) or unstable angina (UA) patients with BSS and healthy controls were enrolled. The miRNA and mRNA expression profiles of UA patients and AIS patients were compared to those of healthy controls to identify the differentially expressed miRNA and mRNA of BSS. Bioinformatics analysis was used to identify significantly deregulated miRNAs and mRNAs correlated to BSS. QRT-PCR was performed to validate the bioinformatics analysis results. RESULTS: Approximately 401 mRNAs and 11 miRNAs were differentially expressed in both UA and AIS patients compared to healthy controls. Gene ontology (GO) functional analysis was performed, and multiple GO terms were enriched. Among the overlapping DE miRNAs and mRNAs, miR-146b-5p, -199a-5p and 23 targeted mRNAs were pivotal genes in the BSS genomic characteristics. These 2 miRNAs and 23 mRNAs formed network-type biomarkers for BSS. CONCLUSIONS: The genomic characteristics of BSS were shown in this study. miR-146b-5p, -199a-5p and the 23 targeted mRNAs formed a diagnostic network for BSS. Further improvement and validation of this diagnostic network might lead to more objective diagnostic criteria for BSS.

Bioinformatics investigation of therapeutic mechanisms of Xuesaitong capsule treating ischemic cerebrovascular rat model with comparative transcriptome analysis.

BACKGROUND: Xuesaitong soft capsule (XST) which consists of panax notoginseng saponin (PNS) has been used to treat ischemic cerebrovascular diseases in China. The therapeutic mechanism of XST has not been elucidated yet from prospective of genomics and bioinformatics. METHODS: A transcriptome analysis was performed to review series concerning middle cerebral artery occlusion (MCAO) rat model and XST intervention after MCAO from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were compared between blank group and model group, model group and XST group. Functional enrichment and pathway analysis were performed. Protein-Protein interaction network was constructed. The overlapping genes from two DEGs sets were screened out and profound analysis was performed. RESULTS: Two series including 22 samples were obtained. 870 DEGs were identified between blank group and model group, and 1189 DEGs were identified between model group and XST group. GO terms and KEGG pathways of MCAO and XST intervention were significantly enriched. PPI networks were constructed to demonstrate the gene-gene interactions. The overlapping genes from two DEGs sets were highlighted. ANTXR2, FHL3, PRCP, TYROBP, TAF9B, FGFR2, BCL11B, RB1CC1 and MBNL2 were the pivotal genes and possible action sites of XST therapeutic mechanisms. CONCLUSION: MCAO is a pathological process with multiple.

Xuefuzhuyu decoction for hyperlipidemia: a systematic review and meta-analysis of randomized clinical trails.

OBJECTIVE: To evaluate the efficacy and safety of Xuefuzhuyu decoction for hyperlipidemia. METHODS: Randomized clinical trials on hyperlipidemia treated by Xuefuzhuyu decoction, either alone or with Western Medicine, were searched in electronic databases. Databases searched were: MEDLINE, Allied and Complementary Medicine Database, EMBASE, The Cochrane Library 2013 (Issue 4), China National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, and Wanfang Database up to 2 May, 2013. Study selection, data extraction, quality assessment, and data analysis were conducted according to the Cochrane standards. RESULTS: Six randomized clinical trials involving 748 patients (373 patients in the treatment group, 375 patients in the control group) were included in the analysis. The studies were of low methodological quality. Meta-analysis indicated that the effect of Xuefuzhuyu decoction on hyperlipidemia was better than that in the control group [n = 748, OR = 5.07, 95% CI (3.40, 7.58), P < 0.01]. Weighted mean differences in total cholesterol, low-density lipoprotein cholesterol, triglycerides, and high-density lipoprotein cholesterol were - 0.79, - 0.74, - 0.44, 0.16, respectively, and Meta-analysis revealed that the treatment group was better than the control group with 95% CI (- 1.21, - 0.36),(- 0.94, - 0.55), (- 0.77, - 0.11), (0.04, 0.27), respectively (all P < 0.05). Some adverse events in evaluated studies were recorded. CONCLUSION: Xuefuzhuyu decoction may be effective for treating hyperlipidemia. The studies we analyzed were of low methodological quality, which indicates that the above findings should be considered cautiously. Therefore, more strictly designed large-scale randomized clinical trials are needed to evaluate the efficacy of Xuefuzhuyu decoction in hyperlipidemia.

Xiangshaliujunzi Decoction for the treatment of diabetic gastroparesis: a systematic review.

AIM: To assess the current clinical evidence of the effectiveness of Xiangshaliujunzi Decoction (XSLJZD) for the treatment of diabetic gastroparesis (DGP). METHODS: Randomized controlled trials (RCTs) were retrieved from seven major electronic databases including Medline, the Cochrane Library, Embase, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database (VIP), and Wanfang Databases, using search dates from the beginning of the databases to May 2013. No language limitations were applied. We included RCTs that used XSLJZD or a modified XSLJZD compared with a control group for the treatment of DGP. The control groups included conventional treatment (Western medicinal treatment), placebo, and no treatment (blank), but not acupuncture. The main outcome index was clinical effectiveness, which was based on the gastric emptying test and variations in the gastrointestinal (GI) symptoms between the treatment and control groups after intervention. Data extraction, analysis, and quality assessment were conducted according to the Cochrane Handbook for Systematic Review of Interventions, Version 5.1.0. RESULTS: Ten RCTs involving 867 patients (441 in the experimental groups, and 426 in the control groups) were identified, and the overall methodological quality was evaluated as generally low. In the treatment groups, all 10 trials used herbs alone as the treatment, whereas all control groups used prokinetic medicine. The period of intervention ranged from 2 to 8 wk. Three classes were used to evaluate treatment efficacy: significant effective, effective, and ineffective, and all trials used the clinical effective rate (based on the gastric emptying test and changes in GI symptoms) to evaluate efficacy. The data showed that the effects of XSLJZD for the treatment of DGP were superior to the control group (n = 867, RR =1.33, 95%CI: 1.24-1.42, Z = 8.11, P < 0.00001). Two trials recorded adverse events, and one trial reported follow-up. CONCLUSION: XSLJZD could restore the gastric emptying rate and improve symptoms. However, the evidence remains weak due to the poor methodological quality of the included studies.

Chinese herbal medicine banxiaxiexin decoction treating diabetic gastroparesis: a systematic review of randomized controlled trials.

Objective. To assess the current clinical evidence of Banxiaxiexin decoction for diabetic gastroparesis (DGP). Methods. Electronic databases were searched until December 2012. No language limitations were applied. We included RCTs using Banxiaxiexin decoction/modified Banxiaxiexin decoction for DGP. No restriction for the control group except acupuncture. Applying clinical effective rate as the main outcome index. Data extraction, analyses and quality assessment were conducted according to the Cochrane review standards. Results. 16 RCTs involving 1302 patients were finally identified, and the methodological quality was evaluated as generally low. The data showed that the effect of Banxiaxiexin decoction (BXXD) for DGP was superior to the control group (n = 1302, RR 1.23, 95% CI 1.17 to 1.29, Z = 8.04, P < 0.00001). Only one trial recorded adverse events, no obvious adverse event occurred. Conclusions. Banxiaxiexin decoction could regain the gastric emptying rate and improve diabetic gastrointestinal symptoms. However, the methodological quality of included studies is low, and long term efficacy and safety are still uncertain, which indicates that the findings above should be read with caution. Thereby, well-designed, large-scale, and high-quality randomized controlled clinical trials with scientific rigor are warranted for stronger evidence in future research.
