ABSTRACT
OBJECTIVE@#High-fat diet is one of the main risk factors that disrupt the balance of gut microbiota, which eventually will induce colorectal cancer (CRC). Evodiamine (EVO) is a wildly used multifunctional traditional Chinese medicine extract. In this study, we investigated the role of gut microbiota in high-fat diet-propelled CRC and the potential of EVO for CRC chemoprevention.@*METHODS@#Gut microbiota, serum d-lactic acid and endotoxin from 38 patients with colon cancer and 18 healthy subjects were detected by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA). In addition, body mass index, phospho-signal transducer and activator of transcription 3 (p-STAT3) expression in cancer tissues and paracancerous tissues were detected by immunohistochemistry. A mouse intestinal inflammatory tumor model was established by azomethane/sodium dextran sulfate, followed by treatment with EVO and 5-aminosalicylic acid (ASA). Gut microbiota and inflammatory factors were detected by quantitative polymerase chain reaction, while serum d-lactic acid and endotoxin were detected by ELISA. Furthermore, cell proliferation, cell apoptosis, and interleukin (IL)-6/STAT3/P65 pathway were evaluated by 5-ethynyl-2'-deoxyuridine, terminal-deoxynucleotidyl transferase-mediated nick-end labeling, and Western blot assays.@*RESULTS@#In patients with colon cancer, the numbers of Enterococcus faecalis and Escherichia coli were increased, while those of Bifidobacterium, Campylobacter and Lactobacillus were decreased. Serum endotoxin and d-lactic acid levels and p-STAT3 levels were significantly increased. In the mouse model, both EVO and ASA inhibited tumor formation, decreased the proliferation of tumor cells, and induced apoptosis of tumor cells. Compared with the control group, the numbers of E. faecalis and E. coli were decreased, while Bifidobacterium, Campylobacter and Lactobacillus numbers were increased. In the EVO group, serum endotoxin and d-lactic acid levels and inflammatory factors were significantly decreased. Further, the IL6/STAT3/P65 signaling pathway was inhibited in the EVO group.@*CONCLUSION@#EVO may inhibit the occurrence of colon cancer by regulating gut microbiota and inhibiting intestinal inflammation. The potential mechanism involves inhibition of the IL6/STAT3/P65 signaling pathway, revealing its potential therapeutic significance in clinical applications.
ABSTRACT
This study aims to explore the efficacy of Chinese medicine injections( CMIs) for promoting blood circulation and removing blood stasis for acute cerebral infarction from the perspectives of clinical medication and mechanism of action based on two complex network analysis methods. Firstly,the current 13 kinds of CMIs for acute cerebral infarction were obtained from 2019 List of medicines for national basic medical insurance,industrial injury insurance and maternity insurance with the method of network Meta-analysis. Secondly,with the use of network pharmacology,the mechanisms of top 2 CMIs with the highest therapeutic effect for acute cerebral infarction were explored from two levels including core target and network function enrichment. The result of network Meta-analysis showed Mailuoning Injection was superior to Danhong Injection in terms of total effectiveness rate for neurological deficit score and NIHSS score. The network pharmacology results showed that Mailuoning Injection had more core targets,interaction networks,enriched biological functions and more signaling pathways than Danhong Injection for cerebral infarction. Both two CMIs can play a role in treating cerebral infarction through core targets such as TP53 and NOS3,biological processes such as fibrinolysis,nitric oxide biosynthesis,nitric oxide-mediated signal transduction,negative regulation of apoptosis in endothelial cells and apoptosis process,as well as the signaling pathways such as PI3 K-Akt signaling pathway,HIF-1 signaling pathway and cell apoptosis signaling pathways. The results of pharmacological studies explained their differences in clinical efficacy to a certain extent. A research strategy based on curative effect should be advocated in efficacy evaluation of traditional Chinese medicine,where comparative research on clinical efficacy can be conducted firstly,and then mechanism research based on outstanding effective drugs to better provide references and basis for selection of similar competitive drugs for one disease in the clinical practice.

The purpose of this study was to evaluate the selection situation of outcome indexes in randomized controlled trials of traditional Chinese medicine(TCM) in the treatment of acute ischemic stroke and to provide suggestions for future research. In this study, four Chinese databases and three English databases were searched from January 2017 to June 2019. The randomized controlled trials of traditional Chinese medicine in the treatment of ischemic stroke were selected according to the pre-established selection criteria. Cochrane bias risk assessment tool was used to evaluate the quality of the included studies. A total of 20 651 related articles were searched, and 11 662 ones were left after eliminating the repetitions. Finally, 42 articles were included, including 36 articles in Chinese and 6 articles in English, 40 randomized controlled trials and 2 registration schemes of randomized controlled trials. The results showed that the outcome indexes of 42 randomized controlled trials were mainly divided into seven categories, that is clinical outcome index, blood biochemical index, mental state evaluation index, cerebral hemodynamics index, index of evaluating the degree of carotid artery stenosis, safety indicators and other indicators. The blood biochemical index was the one with highest frequency, followed by the clinical outcome index. TCM syndrome score was used as an indicator of curative outcome in 17 studies. After the analysis, it was found that there were many problems in selecting the outcome indexes for the randomized controlled trials of traditional Chinese medicine in the treatment of cerebral apoplexy. For example, the end point index and hard index were rarely selected as the main outcome indicators, and the vast majority of them were intermediate alternative indexes; recognized curative effect could not be obtained; there were too many kinds of outcome indicators and excessive heterogeneity, hindering the promotion of superior treatment measures of traditional Chinese medicine in clinical practice. Therefore, we should draw lessons from the establishment method of the international core index outcome index set, construct the core index outcome index set of traditional Chinese medicine in the treatment of ischemic stroke, and develop the outcome index set which accords with the curative effect characteristics of traditional Chinese medicine treatment mea-sures to solve the problems effectively.

To systematically evaluate the efficacy and safety of Xiangsha Yangwei Pills in the treatment of chronic gastritis. Compu-ter retrieval was performed for Cochrane Library, Medline, EMbase, China Knowledge Network Database(CNKI), China Biomedical Literature Service System(SinoMed), Chongqing Weipu Chinese Science and Technology Journal Database(VIP) and WanFang Database(WanFang) randomized controlled trials about Xiangsha Yangwei Pills combined with Western medicine in the treatment of chro-nic gastritis. The retrieval time ranged from the establishment of the library to April 26, 2019. Meta-analysis was performed by RevMan 5.3 software after two independent researchers conducted literature screening, data extraction and quality evaluation according to inclusion and exclusion criteria. A total of 1 720 patients were enrolled in 18 RCT. According to the classification of chronic gastritis, they were divided into three subgroups: chronic gastritis, chronic atrophic gastritis and chronic superficial gastritis. The results of Meta-ana-lysis showed that the efficacy of Xiangsha Yangwei Pills combined with Western medicine in treating chronic gastritis was higher than that of Western medicine. As for the recurrence rate, Xiangsha Yangwei Pills combined with Western medicine was lower than Western medicine. And there was no statistical difference about helicobacter pylori(Hp) eradication rate between Xiangsha Yangwei Pills combined with Western medicine as well as Western medicine. In terms of the incidence of adverse reactions, Xiangsha Yangwei Pills combined with Western medicine was lower than Western medicine, and no serious adverse reaction was reported. The results of this systematic review showed that compared with the conventional Western medicine group, Xiangsha Yangwei Pills combined with Western medicine can significantly alleviate clinical symptoms of chronic gastritis, with fewer adverse reactions. However, due to the low methodological quality of the included studies and the reliability of the impact conclusions, high-quality multi-center, large-sample, randomized, double-blind controlled trials are needed for validation.

The efficacy of oral Chinese patent medicine in the treatment of acute cerebral infarction was systematically evaluated by network Meta-analysis. The literature search was conducted in three English databases(Medline, EMbase and Cochrane Library) and four Chinese databases(CNKI, VIP, WanFang and SinoMed) from inception to June 2018, and the randomized controlled trials of acute cerebral infarction were screened out according to the pre-set criteria. Two reviewers independently screened out the literature by using pre-specified eligibility criteria, and assessed the quality of included studies according to the risk of bias tool of Cochrane Handbook 5.1.0. Data analysis was conducted by using Stata 13.0 and WinBUGS 1.4.3 software. Finally, 52 RCT were included, involving 11 kinds of oral Chinese patent medicines. The results of the network Meta-analysis showed that in terms of the total effective rate, the order of efficacy was as follows: Naomaitai Capsules>Xiaoshuan Changrong Capsules>Angong Niuhuang Pills>Yangxue Qingnao Granules>Compound Danshen Dripping Pills>Naoxintong Capsules>Tongxinluo Capsules>Naoxueshu Oral Liquid>Zhuyu Tongmai Capsules>Yinxingye Tablets>Compound Danshen Tablets; in terms of neurological deficit scores, the order of efficacy was: Tongxinluo Capsules>Angong Niuhuang Pills>Compound Danshen Dripping Pills>Xiaoshuan Changrong Capsules>Yangxue Qingnao Granules>Zhuyu Tongmai Capsules>Naoxintong Capsules>Naoxueshu Oral Liquid; in terms of Barthel index score, the order of efficacy was: Xiaoshuan Changrong Capsules>Naomaitai Capsules>Naoxueshu Oral Liquid>Angong Niuhuang Pills>Tongxinluo Capsules>Zhuyu Tongmai Capsules. Although different oral Chinese patent medicines can improve these outcomes, the difference in efficacy ranking was relatively large. Because of the small number and low quality of research literature, the conclusion still needs to be proved by multi-center, large-sample, and double-blind randomized trials.

To systematically review the effectiveness and safety of Kudiezi Injection in treating patients with acute cerebral infarction( ACI). Four Chinese databases( CNKI,VIP,Wan Fang,Sino Med),three English databases( Cochrane Library,EMbase,Medline)and Clinical Trail.gov were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to November 2017. Randomized controlled trials( RCTs) for the treatment of acute cerebral infarction with Kudiezi Injection were screened out according to pre-established inclusion criteria and exclusion criteria. The quality of the included studies was assessed using the Cochrane Risk Assessment Tool,and the included studies were put into descriptive analysis or Meta-analysis using the Rev Man 5. 3 software. A total of 932 articles were retrieved,and finally 14 studies were included. Except for 2 multi-arm trials,the total sample size was 1 244 in the experimental group and 638 in the control group. The overall quality of the included studies was not high. The results of Meta-analysis showed that Kudiezi + conventional therapy for acute cerebral infarction was superior to conventional therapy in total effective rate( RR = 0. 86,95% CI[0. 77,0. 96],P = 0. 006); Kudiezi + conventional therapy for acute cerebral infarction was superior to conventional therapy in serum inflammatory factors( MDhs-CRP=-3. 77,95% CI[-4. 17,-3. 37],P < 0. 000 01; MDIL-18=-16. 18,95% CI[-19. 26,-13. 11],P<0. 000 01); Kudiezi + conventional therapy was superior to conventional therapy in Barthel index( MD = 12. 52,95%CI[8. 93,16. 10],P<0. 000 01). Adverse reactions included in the study reports showed mild adverse reactions. Based on the results of this study,Kudiezi Injection combined with conventional therapy or other Western medicine had a certain curative effect on acute cerebral infarction,with no serious adverse reactions. However,due to the low quality of the included research methodology,the conclusions of this study were not recommended. In addition,in order to produce high-quality evidence for the clinical application of Kudiezi Injections,more randomized controlled trials with a large sample size,scientific design and strict implementation were required to study the effectiveness and safety of Kudiezi Injection in the treatment of cerebral infarction.

To evaluate the methodological quality and reporting quality of randomized controlled trials(RCTs) published in China Journal of Chinese Materia Medica, we searched CNKI and China Journal of Chinese Materia webpage to collect RCTs since the establishment of the magazine. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of RCTs. The CONSORT 2010 list was adopted as reporting quality evaluating tool. Finally, 184 RCTs were included and evaluated methodologically, of which 97 RCTs were evaluated with reporting quality. For the methodological evaluating, 62 trials(33.70%) reported the random sequence generation; 9(4.89%) trials reported the allocation concealment; 25(13.59%) trials adopted the method of blinding; 30(16.30%) trials reported the number of patients withdrawing, dropping out and those lost to follow-up;2 trials (1.09%) reported trial registration and none of the trial reported the trial protocol; only 8(4.35%) trials reported the sample size estimation in details. For reporting quality appraising, 3 reporting items of 25 items were evaluated with high-quality,including: abstract, participants qualified criteria, and statistical methods; 4 reporting items with medium-quality, including purpose, intervention, random sequence method, and data collection of sites and locations; 9 items with low-quality reporting items including title, backgrounds, random sequence types, allocation concealment, blindness, recruitment of subjects, baseline data, harms, and funding;the rest of items were of extremely low quality(the compliance rate of reporting item<10%). On the whole, the methodological and reporting quality of RCTs published in the magazine are generally low. Further improvement in both methodological and reporting quality for RCTs of traditional Chinese medicine are warranted. It is recommended that the international standards and procedures for RCT design should be strictly followed to conduct high-quality trials. At the same time, in order to improve the reporting quality of randomized controlled trials, CONSORT standards should be adopted in the preparation of research reports and submissions.

To evaluate the report quality of intervention-related systematic reviews or Meta-analysis published in China Journal of Chinese Materia Medica, we searched CNKI and China Journal of Chinese Materia Medica webpages to collect intervention-related systematic reviews or Meta-analysis since the first issue of the magazine. A total of 40 systematic reviews or Meta-analysis reports were included, including one network Meta-analysis. According to the PRISMA statement published in 2009, the report quality of the systematic reviews or Meta-analysis was evaluated. According to the results, 3 had the low quality, 30 had the medium quality, and 7 had the high quality. The average score for all of items was 30 points (21-30.5 points for the medium quality). The 17 high-quality (31-40 points) report items were title, rationale, objectives, information sources, study selection, data collection process, data items, risk of bias in individual studies, summary measures, risk of bias across studies, study selection, study characteristics, risk of bias within studies, results of individual studies, synthesis of results, risk of bias across studies and funding; the 4 medium-quality (21-30.5 points) reporting items were eligibility criteria, search, limitations and conclusions; and the 6 low-quality (<=20.5 points) reporting items were structured summary, protocol and registration, synthesis of results, additional analysis (No.16), additional analysis (No.23) and summary of evidence. Through the analysis, it is found that the report quality of intervention-related systematic reviews or Meta-analysis published in China Journal of Chinese Materia Medica is medium, and it is necessary to improve the quality standard of the report.
ABSTRACT
To evaluate the effectiveness and safety of Kudiezi injection in the treatment of angina pectoris of coronary heart disease. Four Chinese databases (CNKI, VIP, WanFang, and SinoMed) and three English databases (Cochrane Library, Medline, and ClinicalTrail.gov) were systematically and comprehensively searched from the establishment of each database to March 2018. Randomized controlled trials (RCTs) on the treatment of angina pectoris of coronary heart disease with Kudiezi injection (KDZ) were screened according to the pre-established inclusion criteria and exclusion criteria. The quality of the included studies was evaluated by using the ROB tool developed by the Cochrane Collaboration, and RevMan 5.3 software was used for Meta-analysis. A total of 712 articles were retrieved and finally 38 studies were included. The total sample size was 3 812 cases, 1 945 in the experimental group and 1 867 in the control group. The overall quality of the included studies was generally low. The results of Meta-analysis showed that: KDZ combined with conventional or western medicine was superior to conventional or western medicine alone in the effectiveness and electrocardiogram efficacy of angina pectoris and unstable angina. The descriptive analysis showed that KDZ combined with conventional treatment group was superior to conventional treatment group in agina pectoris associated indicators of angina pectoris and unstable angina. Other outcome measures were easily affected by various factors (such as too large heterogeneity of outcome indicators) and could not be concluded. Adverse reactions included in the study report were all mild adverse reactions and did not affect treatment. Based on the results of this study, it can be seen that Kudiezi injection had a certain effect on the treatment of angina pectoris of coronary heart disease, especially with significant positive effect on the improvement of the curative effect for angina pectoris and the effect of electrocardiogram. No serious adverse reactions occurred. However, due to the limited number of studies included, the generally low quality of the included studies, and the existence of published biases, the quality of the evidence in this study was low, so that caution should be taken to apply this conclusion. The effectiveness and safety of Kudiezi injection in the treatment of angina pectoris of coronary heart disease remained to be confirmed in the future with a well-designed and rigorous multi-center randomized controlled trials with standardized report, large sample, and enough follow-up time.
