Network meta-analysis of Chinese herbal injections combined with the chemotherapy for the treatment of pancreatic cancer

Combined traditional Chinese medicine therapy for the treatment of infertility with polycystic ovary syndrome: A network meta-analysis of randomized controlled trials

BACKGROUND

Polycystic ovary syndrome (PCOS) infertility has attracted great attention from researchers due to its high incidence. Numerous studies have shown that Chinese medicine is effective in treating this disease, but there is a wide variety of Chinese medicine therapies available, and there is a lack of comparative evaluation of the efficacy of various Chinese medicine combination therapies in the clinic, which requires further in-depth exploration. This study aims to evaluate the efficacy of a combined traditional Chinese medicine (TCM) therapy for the treatment of infertility with PCOS using network meta-analysis (NMA).

METHODS

In PubMed, web of Science, Cochrane Library, Embase, China Knowledge Network, Wanfang Data, VIP Database, China Biomedical Literature Database (SinoMed) databases, searchs were conducted for information about the randomized controlled trials (RCTs) of combined TCM therapy for the treatment of infertility with PCOS. Quality evaluation was performed using the Cochrane 5.3 risk of bias assessment tool, and NMA using Stata 16.0.

RESULTS

This study comprised 28 RCTs using 8 combined TCM therapies in total. The results of the NMA showed that moxibustion + herbal, fire acupuncture + herbal, acupuncture + herbal, electroacupuncture + herbal, and acupoint application + herbal improved the clinical pregnancy rate better than acupuncture, herbal, and western medicines monotherapy (P < .05). Additionally, ear point pressure + herbal enema + herbal, acupuncture and moxibustion + herbal, fire acupuncture + herbal, and acupuncture + herbal improved the ovulation rate better than acupuncture, herbal, and western medicines monotherapy (P < .05). Moxibustion + herbal, fire acupuncture + herbal, and acupuncture + herbal are the 3 most effective therapies for improving the clinical pregnancy rate. Fire acupuncture + herbal, acupuncture + herbal, and ear point pressure + herbal enema + herbal are the 3 most effective therapies for improving the ovulation rate.

CONCLUSION

The combined TCM therapy demonstrated better efficacy for the treatment of infertility with PCOS compared to acupuncture, herbal, and western medicines monotherapy. However, the optimal treatment therapy varied depending on the outcome indicators. Further large sample, high-quality, and standardized RCTs are needed to verify these findings.

Effect of different interventions on the treatment of high-risk human papillomavirus infection: a systematic review and network meta-analysis

Background

Persistent infection with high-risk human papillomavirus (HR-HPV) can lead to cervical intraepithelial neoplasia and cancer. At present, there is no medication that specifically targets HR-HPV infection.

Objective

This study aimed to evaluate the effectiveness of different interventions in promoting HR-HPV regression using a MeSH meta-analysis method.

Methods

A search for randomized controlled trials (RCTs) reporting different interventions for the treatment of HR-HPV infection included PubMed, Web of Science, Embase and Cochrane Library from the inception of the databases to March 8, 2023. Two researchers independently screened the articles, extracted data, and evaluated the quality. The literature that met the inclusion criteria was selected, the quality and risk of bias of the included studies were assessed according to the Cochrane 5.1 manual, and NMA was performed using Stata 16.0. The area under the cumulative ranking probability graph (SUCRA) represented the probability that each treatment would be the best intervention.

Results

Nine studies involving 961 patients and 7 treatment options were included in the analysis. The results of the network meta-analysis indicated the following rank order in terms of promoting HR-HPV conversion: Anti-HPV biological dressing > vaginal gel > imiquimod > REBACIN® > interferon > probiotics > observation/placebo > Polyphenon E.

Conclusion

Anti-HPV biological dressing treatment was found to be significantly effective in promoting HR-HPV conversion. However, further validation of the findings is necessary due to the limited number and quality of studies included in the analysis.

Chinese herbal injections in combination with radiotherapy for advanced pancreatic cancer: A systematic review and network meta-analysis

Background

Advanced pancreatic cancer (APC) is a fatal disease with limited treatment options. This study aims to evaluate the effectiveness and safety of different Chinese herbal injections (CHIs) as adjuvants for radiotherapy (RT) in APC and compare their treatment potentials using network meta-analysis.

Methods

We systematically searched three English and four Chinese databases for randomized controlled trials (RCTs) from inception to July 25, 2023. The primary outcome was the objective response rate (ORR). Secondary outcomes included Karnofsky performance status (KPS) score, overall survival (OS), and adverse events (AEs). The treatment potentials of different CHIs were ranked using the surface under the cumulative ranking curve (SUCRA). The Cochrane RoB 2 tool and CINeMA were used for quality assessment and evidence grading.

Results

Eighteen RCTs involving 1199 patients were included. Five CHIs were evaluated. Compound Kushen injection (CKI) combined with RT significantly improved ORR compared to RT alone (RR 1.49, 95 % CrI 1.21-1.86). Kanglaite (KLT) plus RT (RR 1.58, 95 % CrI 1.20-2.16) and CKI plus RT (RR 1.49, 95 % CrI 1.16-1.95) were associated with improved KPS score compared to radiation monotherapy, with KLT+RT being the highest rank (SUCRA 72.28 %). Regarding AEs, CKI plus RT was the most favorable in reducing the incidence of leukopenia (SUCRA 90.37 %) and nausea/vomiting (SUCRA 85.79 %).

Conclusions

CKI may be the optimal choice of CHIs to combine with RT for APC as it may improve clinical response, quality of life, and reduce AEs. High-quality trials are necessary to establish a robust body of evidence.

Current status of Complementary and Alternative Medicine Interventions in the Management of Pancreatic Cancer - An Overview

OPINION STATEMENT

Pancreatic cancer (PC) remains the deadliest cancer worldwide. Most patients are diagnosed at the advanced or metastatic stage, leading to a poor prognosis. Awareness of the limitations of current therapy and accompanying pain, depression, malnutrition, and side effects of chemoradiotherapy may lead patients and physicians towards complementary and alternative medicine (CAM). CAM refers to a diverse set of medical and healthcare practices, products, and systems that are not part of conventional Western medicine. Despite the low-quality evidence supporting the efficacy of these methods, they remain appealing due to patients' beliefs, fear of death, and the slow development of conventional therapy. Hence, the possibility of using natural products for pancreatic cancer is increasing. CAM options such as: medical cannabis, plants, fungi, herbal formulas, and injections, which originate primarily from traditional Chinese or Japanese medicine i.e. Curcuma longa, Panax ginseng, Poria cocos, Hochuekkito, Juzentaihoto, and Rikkunshito, Shi-quan-da-bu-tang/TJ-48, Huang-qin-tang, Shuangbai San, Wen Jing Zhi Tong Fang, Xiang-Sha-Liu-jun-zi-tang, Aidi injection, Brucea javanica oil emulsion/Yadanziyouru injection, Compound Kushen injection, Huachansu injection, Kangai injection and Kanglaite injections are becoming promising candidates for the management of pancreatic cancer. The abovementioned substances/medications are the most popular or potentially effective in PC treatment and consequently CAM-based adjuvant therapy through improving patients' quality of life, might be a useful addition in the treatment of pancreatic cancer patients.

Comparative efficacy and safety of Chinese medicine injections combined with capecitabine and oxaliplatin chemotherapies in treatment of colorectal cancer: A bayesian network meta-analysis

Objective: The aim of the present Bayesian network meta-analysis (NMA) was to explore the comparative effectiveness and safeaty of different Chinese Medicine injections (CMIs) combined with the XELOX regimen versus XELOX alone for colorectal cancer (CRC). Methods: A comprehensive search for randomized controlled trials (RCTs) was performed with regard to different CMIs for the treatment of CRC in several electronic databases up to April 2022. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Standard pair-wise and Bayesian NMA were designed to comparethe effectiveness and safety of different CMIs combined with the XELOX regimen by utilizing R 4.0.3 software and Stata 15.1 software simultaneously. Results: Initially, a total of 4296 citations were retrieved through comprehensive searching, and 32 eligible articles involving 2847 participants and 11 CMIs were ultimately included. CMIs combined with XELOX were superior to the XELOX regimen alone, and a total of ten Observation Indicators were included in the study, with the following results. Among all the injections, Shengmaiyin, Shenmai, and Kanglaite combined with the XELOX regimen were the three CMIs with the highest clinical efficiency. The top three in terms of improving CD3+ values were Shengmaiyin, Shenqifuzheng, and Cinobufacini injections. Shenqifuzheng, Shengmaiyin, and BruceaJavanica oil injections combined with the XELOX regimen performed best at raising CD4+ values. Kanglaite, Cinobufacini, and Matrine injections combined with the XELOX regimen performed best in improving CD4+/CD8+ rates. The top three in terms of improving performance status were Xiaoaiping, Shenmai, and Kanglaite injections. Cinobufacini and Brucea Javanica oil injections combined with the XELOX regimen performed best at raising CD8+ values. Shenqifuzheng, Kangai, and Matrine injections combined with the XELOX regimen performed best in improving Gastrointestinal reactions.The top threein terms of improving Leukopenia were Shenqifuzheng, Compound Kushen and Kanglaite injections. The top three in terms of improving Platelet decline were Compound Kushen, Cinobufacini and Shenqifuzheng injections. Additionally, those that were best at improving nausea and vomitting were Cinobufacini, Compound Kushen and Aidi injections. Conclusion: The results of the analysis demonstrated thatShengmaiyin, Kanglaite, and Cinobufacini injections and the XELOX regimen were associated with morepreferable and beneficial outcomes than other CMI groups. Nevertheless, additional results from multicenter trials and high-quality studies will bevital to support our findings.

Efficacy and safety of traditional Chinese medicine for the treatment of pancreatic cancer: An overview of systematic reviews and meta-analyses

Pancreatic cancer is a highly malignant tumor with poor prognosis. Currently available Western medical management strategies are unable to prolong the survival time and reduce the mortality of patients with pancreatic cancer. Traditional Chinese medicine has achieved promising results in many clinical studies. This systematic review and meta-analysis (SR/MA) aimed to explore the benefits and evaluate the quality of evidence of traditional Chinese medicine-based interventions for preventing and treating pancreatic cancer. A systematic search of eight databases for SRs/MAs of randomized controlled trials on traditional Chinese medicine treatment for pancreatic cancer was conducted (from inception to April 2022). The methodological quality of the SRs/MAs was assessed using AMSTAR 2.0, and the quality of evidence was evaluated using the GRADE guide. Nine SRs/MAs, including 145 randomized controlled trials, were considered eligible for this study. The literature were published between 2014 and 2022. The sample size of randomized controlled trials in the MAs ranged from 336 to 1,989. The methodological quality of the nine studies was critically low. Among the 59 outcome indicators of the nine SRs/MAs, seven, 33, and 19 had moderate-, low-, and critically low-quality evidence, respectively, while high-quality evidence was not identified. The results for the long-term indicators, short-term indicators, and adverse reactions in the SRs/MAs displayed consistencies and differences. In conclusion, the methodological and evidence quality of the current evidence is generally low, highlighting the need for additional focus on implementation processes. Some evidence with moderate quality validated that several specific traditional Chinese medicine were optimum for improving the short-term clinical efficacy. However, more objective and high-quality investigations are warranted to verify the efficacy of traditional Chinese medicine for pancreatic cancer.

Systematic Review and Network Meta-analysis of Acupuncture Combined with Massage in Treating Knee Osteoarthritis

Background

Knee osteoarthritis is a common clinical disease with frequent occurrence. More and more studies have shown that external therapies such as acupuncture and massage are beneficial to the treatment of knee osteoarthritis.

Objective

The purpose of this systematic review and meta-analysis of randomized controlled trials (RCTS) was to evaluate the efficacy and safety of acupuncture and massage combined with treatment of KOA and to provide some reference for clinical treatment of KOA.

Methods

Network meta-analysis was used to evaluate the efficacy of acupuncture combined with massage in the treatment of knee osteoarthritis. PubMed, Cochrane Library, Web of Science, Embase, Chinese Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP, and Wanfang were searched by computer for randomized controlled trials on acupuncture combined with massage in the treatment of knee osteoarthritis. All researchers independently screened the literature, extracted data, and evaluated quality, and studies that met the quality criteria were analyzed using Stata16.0 software.

Results

A total of 3076 articles were retrieved, and finally, 49 studies involving 10 acupuncture combined with massage methods were included. The total sample size was 4458, including 2182 in the experimental group and 2276 in the control group. The results of network meta-analysis showed the following: in terms of effective rate, the optimal first three interventions were floating needle+massage, needle knife+massage, and silver needle+massage; in terms of reducing VAS score, the optimal first three interventions were common acupuncture+massage, needle knife+massage, and warm needle+massage; in terms of improving total Lysholm index score, the optimal first three interventions were silver needle+massage, electroacupuncture+massage, and needle knife+massage; in terms of reducing total WOMAC score, the optimal first three interventions were silver needle+massage, electrothermal needle+massage, and common acupuncture+massage; in terms of reducing WOMAC stiffness score, the optimal first three interventions were warm needle+massage, silver needle+massage, and common acupuncture+massage; and in terms of reducing WOMAC joint function score, the optimal first three interventions were silver needle+massage, warm needle+massage, and common acupuncture+massage.

Conclusion

The results showed that acupuncture combined with massage could improve the clinical therapeutic effect of patients with knee osteoarthritis. Limited by the quality of the included studies, the conclusions obtained still need to be further validated.

Gene Differential Expression and Interaction Networks Illustrate the Biomarkers and Molecular Biological Mechanisms of Unsaponifiable Matter in Kanglaite Injection for Pancreatic Ductal Adenocarcinoma

Background

Kanglaite injection (KLTi) has shown good clinical efficacy in the treatment of pancreatic ductal adenocarcinoma (PDAC). While previous studies have demonstrated the antitumor effects of the oil compounds in KLTi, it is unclear whether the unsaponifiable matter (USM) also has antitumor effects. This study used network pharmacology, molecular docking, and database verification methods to investigate the molecular biological mechanisms of USM.

Methods

Compounds of USM were obtained from GC-MS, and targets from DrugBank. Next, the GEO database was searched for differentially expressed genes in cancerous tissues and healthy tissues of PDAC to identify targets. Subsequently, the protein-protein interaction of USM and PDAC targets was constructed by BisoGenet to extract candidate genes. The candidate genes were enriched using GO and KEGG by Metascape, and the gene-pathway network was constructed to screen the key genes. Molecular docking and molecular dynamic simulations of core compound targets were finally performed and to explore the diagnostic, survival, and prognosis value of targets.

Results

A total of 10 active compounds and 36 drug targets were screened for USM, 919 genes associated with PDAC, and 139 USM candidate genes against PDAC were excavated. The enrichment predicted USM by acting on RELA, NFKB1, IKBKG, JUN, MAPK1, TP53, and AKT1. Molecular docking and dynamic simulations confirmed the screened core targets had good affinity and stability with the corresponding compounds. In diagnostic ROC validation, the above targets have certain accuracy for diagnosing PDAC, and the combined diagnosis is more advantageous. As the most diagnostic value of RELA, it is equally significant in predicting disease-specific survival and progression-free interval.

Conclusions

USM in KLTi plays an anti-PDAC role by intervening in the cell cycle, inducing apoptosis, and downregulating the NF-κB, MAPK, and PI3K-Akt pathways. It might participate in the pancreatic cancer pathway, and core target groups have diagnostic, survival, and prognosis value biomarker significance.

Efficacy of Aidi Injection Combined With Radiotherapy for the Treatment of Nasopharyngeal Carcinoma: A Systematic Review and Meta-Analysis

Objective: Radiotherapy (RT) is the first choice in the treatment of nasopharyngeal carcinoma (NPC) but there are many adverse reactions. There is evidence that Aidi injection can improve the effect of RT and reduce the occurrence of adverse reactions after RT, but there is still a lack of evidence-based study. The objective of this study was to evaluate the efficacy and safety of Aidi injection combined with RT in the treatment of NPC. Methods: The PubMed, Cochrane Library, CNKI, EMBASE, Web of Science, CBM, Wanfang, and VIP data were thoroughly searched for randomized controlled trials (RCTs) on Aidi injection combined with RT against NPC until February 2021. The literature was screened, extracted, and evaluated by 2 investigators independently. Meta-analysis was performed by RevMan5.3 and Stata 14.0, and the quality of evidence was evaluated by Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: In this study, we included 9 RCT studies involving 422 patients. The results showed significant between-group differences in complete remission rate (CRR) [relative risk (RR) = 1.17, 95% CI (1.04, 1.31), P = .009], Karnofsky Performance Status Scale (KPS) score [RR = 1.30, 95% CI (1.19, 1.42), P < .00001], leukopenia [RR = 0.65, 95% CI (0.54, 0.78), P < .00001], hemoglobin reduction [RR = 0.60, 95% CI (0.43, 0.84), P = .003], nausea and vomiting [RR = 0.60, 95% CI (0.45, 0.80), P = .0004], oropharyngeal mucosa injury (OMI) [RR = 0.25, 95% CI (0.15, 0.44), P < .00001], but the differences were not statistically significant in total effective rate (TER) [RR = 1.03, 95% CI (0.98, 1.08), P = .20 > 0.05], thrombocytopenia [RR = 0.78, 95%CI (0.52,1.16), P = .22 > .05], and skin injury [RR = 0.81, 95% CI (0.64, 1.04), P = .1 > .05]. Conclusion: Aidi injection combined with RT can improve patients’ quality of life (KPS score) and reduce the adverse reactions caused by RT (such as leukopenia, hemoglobin reductio，OMI，nausea, and vomiting). However, limited by the quality and quantity of the included trials，more high-quality studies should be performed to verify our conclusions.

Matrine injection inhibits pancreatic cancer growth via modulating carbonic anhydrases- a network pharmacology-based study with in vitro validation

ETHNOPHARMACOLOGICAL RELEVANCE

Matrine injection is a complex mixture of plant bioactive substances extracted from Sophora flavescens Aiton and Smilax glabra Roxb. Since its approval by the Chinese Food and Drug Administration (CFDA) in 1995, Matrine injection has been clinically used as a complementary and alternative treatment for various cancers; however, the underlying mechanism of pancreatic cancer treatment is yet to be elucidated.

AIM OF THE STUDY

The present study explores the potential mechanism of matrine injection on pancreatic cancer through network pharmacology technique and in vitro experimental validation.

MATERIALS AND METHODS

Genes differentially expressed in pancreatic cancer were obtained from the Gene Expression Omnibus (GEO) database (GSE101448). The potential active components of matrine injection were selected following a literature search, and target prediction was performed by the SwissTarget Prediction database. Overlapping genes associated with survival were screened by the Gene Expression Profiling Interactive Analysis (GEPIA) database. In vitro experimental validation was performed with cell counting kit-8 (CCK-8) assay, apoptosis detection, cell cycle analysis, immunoblotting, and co-immunoprecipitation of the identified proteins.

RESULTS

One thousand seven hundred genes differentially expressed among pancreatic tumor and non-tumor tissues were screened out. Sixteen active components and 226 predicted target genes were identified in matrine injection. A total of 25 potential target genes of matrine injection for the treatment of pancreatic cancer were obtained. Among them, the prognostic target genes carbonic anhydrase 9 (CA9) and carbonic anhydrase 12 (CA12) based on the GEPIA database are differently expressed in tumors compared to adjacent normal tissue. In vitro experiments, the results of CCK-8 assay, apoptosis and cell cycle analysis, immunoblotting, and co-immunoprecipitation showed that matrine injection inhibited Capan-1 and Mia paca-2 proliferation, arrested the cell cycle at the S phase, and induced apoptosis through up-regulated CA12 and down-regulated CA9.

CONCLUSIONS

In this study, bioinformatics and network pharmacology were applied to explore the treatment mechanism on pancreatic cancer with matrine injection. This study demonstrated that matrine injection inhibited proliferation, arrested the cell cycle, and induced apoptosis of pancreatic cancer cells. The mechanism may be related to the induction of CA12 over-expression, and CA9 reduced expression. As novel targets for pancreatic cancer treatment, Carbonic anhydrases require further study.

Herbals and Plants in the Treatment of Pancreatic Cancer: A Systematic Review of Experimental and Clinical Studies

Background: Pancreatic cancer represents the most lethal malignancy among all digestive cancers. Despite the therapeutic advances achieved during recent years, the prognosis of this neoplasm remains disappointing. An enormous amount of experimental (mainly) and clinical research has recently emerged referring to the effectiveness of various plants administered either alone or in combination with chemotherapeutic agents. Apart from Asian countries, the use of these plants and herbals in the treatment of digestive cancer is also increasing in a number of Western countries as well. The aim of this study is to review the available literature regarding the efficacy of plants and herbals in pancreatic cancer. Methods: The authors have reviewed all the experimental and clinical studies published in Medline and Embase, up to June 2021. Results: More than 100 plants and herbals were thoroughly investigated. Favorable effects concerning the inhibition of cancer cell lines in the experimental studies and a favorable clinical outcome after combining various plants with established chemotherapeutic agents were observed. These herbals and plants exerted their activity against pancreatic cancer via a number of mechanisms. The number and severity of side-effects are generally of a mild degree. Conclusion: A quite high number of clinical and experimental studies confirmed the beneficial effect of many plants and herbals in pancreatic cancer. More large, double-blind clinical studies assessing these natural products, either alone or in combination with chemotherapeutic agents should be conducted.

A network pharmacology approach to reveal the pharmacological targets and biological mechanism of compound kushen injection for treating pancreatic cancer based on WGCNA and in vitro experiment validation

BACKGROUND

Compound kushen injection (CKI), a Chinese patent drug, is widely used in the treatment of various cancers, especially neoplasms of the digestive system. However, the underlying mechanism of CKI in pancreatic cancer (PC) treatment has not been totally elucidated.

METHODS

Here, to overcome the limitation of conventional network pharmacology methods with a weak combination with clinical information, this study proposes a network pharmacology approach of integrated bioinformatics that applies a weighted gene co-expression network analysis (WGCNA) to conventional network pharmacology, and then integrates molecular docking technology and biological experiments to verify the results of this network pharmacology analysis.

RESULTS

The WGCNA analysis revealed 2 gene modules closely associated with classification, staging and survival status of PC. Further CytoHubba analysis revealed 10 hub genes (NCAPG, BUB1, CDK1, TPX2, DLGAP5, INAVA, MST1R, TMPRSS4, TMEM92 and SFN) associated with the development of PC, and survival analysis found 5 genes (TSPOAP1, ADGRG6, GPR87, FAM111B and MMP28) associated with the prognosis and survival of PC. By integrating these results into the conventional network pharmacology study of CKI treating PC, we found that the mechanism of CKI for PC treatment was related to cell cycle, JAK-STAT, ErbB, PI3K-Akt and mTOR signalling pathways. Finally, we found that CDK1, JAK1, EGFR, MAPK1 and MAPK3 served as core genes regulated by CKI in PC treatment, and were further verified by molecular docking, cell proliferation assay, RT-qPCR and western blot analysis.

CONCLUSIONS

Overall, this study suggests that the optimized network pharmacology approach is suitable to explore the molecular mechanism of CKI in the treatment of PC, which provides a reference for further investigating biomarkers for diagnosis and prognosis of PC and even the clinical rational application of CKI.

Coix Seed May Affect Human Immune Function

Coix ( Coix lacryma-jobi Linné . var . mayuen Stapf) is, unlike many herbs used in Chinese traditional medicines, often used as a single agent. Coix seed has its specific constituents coixenolide and coixol. This review summarizes the effects of coix seed on human pathology and physiology, and the roles of coixenolide and coixol on the effects. The comprehensive literature search was conducted using PubMed, Citation Information by National Institute of Informatics of Japan (CiNii), University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR), and ClinicalTrials.gov databases. Some studies suggest that coix seed promotes the spontaneous regression of viral infections of the skin. Meanwhile, kanglite, a purified oil agent used for cancer therapy, has been implied to increase the ratio of CD4 + T cells in the peripheral blood of cancer patients undergoing treatment. These studies seem to indicate that coix seed may affect cellular immune function. However, there are limitations to the individual studies on which the above consideration is based, and thereby, it is not conclusive what specific immune or clinical indices coix seed affects. In addition, the effects of coixol on human immune function have not been clarified. Therefore, coix seed seems promising for health promotion and presents a challengeable and attractive theme for natural product chemists, pharmacologists, immunologists, and clinicians.

The new role of riluzole in the treatment of pancreatic cancer through the apoptosis and autophagy pathways

Pancreatic cancer is always diagnosed at an advanced stage. Hence, chemotherapy becomes the best choice for patients. Therefore, new anticancer drugs for pancreatic cancer are needed. Riluzole (RIL) is mainly used to treat amyotrophic lateral sclerosis clinically, but many previous studies have shown that RIL could inhibit tumors. However, no report has explored the association between RIL and pancreatic cancer. To validate this association, we performed this study. Our data showed that RIL could induce cytotoxicity, block the cell cycle, and inhibit clone formation, apoptosis, and migration in pancreatic cancer cells. Moreover, we demonstrated that RIL could suppress autophagy. However, more experiments will be needed to validate the reliability of our conclusions. In summary, our data suggest that RIL might provide clues for the development of a treatment for human pancreatic cancer in the future.

Radix Tetrastigma Extracts Enhance the Chemosensitivity in Triple-Negative Breast Cancer Via Inhibiting PI3K/Akt/mTOR-Mediated Autophagy

OBJECTIVE

Drug resistance in tumors is one of the major factors that leads to chemotherapy failure. This study aims to investigate the effect of Radix Tetrastigma extracts (RTEs) on Taxol-induced autophagy and the chemosensitivity against drug resistance in triple-negative breast cancer (TNBC).

METHODS

Taxol-resistant MDA-MB-468 (MDA-MB-468/Taxol) cells were induced and treated with RTEs and/or Taxol. Mice were subcutaneously inoculated with MDA-MB- 468/Taxol cells to establish xenograft models. The associated protein levels were measured by western blotting. Flow cytometry, CCK-8 and EdU assay were performed to detect cell apoptosis, viability, and proliferation, respectively.

RESULTS

In MDA-MB-468/Taxol cells, RTEs & Taxol treatment increased cell apoptosis, reduced cell viability and proliferation, up-regulated anti-autophagy marker LC3I/LC3II ratio, and enhanced mTOR level. With RTEs & Taxol treatment, mTOR silencing downregulated LC3I/LC3II ratio, increased cell viability and proliferation, and reduced cell apoptosis, while mTOR overexpression showed the opposite results. PI3K inhibitor reduced AKT and mTOR levels, and the effects on cell activities were similar to the results of mTOR silencing. After RTEs & Taxol injection, xenograft tumor was smaller, and AKT, mTOR, LC3I/LC3II ratio and apoptotic marker cleaved caspase-3 were increased.

CONCLUSION

RTEs enhanced the chemosensitivity of resistant TNBC cells to Taxol through inhibiting PI3K/Akt/mTOR-mediated autophagy.

MICRO

RTEs exerted anti-tumor effects in various cancers, and this study determined its role in TNBC. Taxol-resistant MDA-MB-468 cells were induced and xenograft models were established. We found that RTEs inhibited autophagy of MDA-MB-468/Taxol cells and reduced tumor growth. Inhibition of PI3K/Akt/mTOR pathway promoted autophagy of MDA-MB-468/Taxol cells. We may provide a new potential strategy for TNBC treatment.

Aidi injection combined with chemotherapy in the treatment of cancer patients: a systematic review of systematic reviews and meta-analyses

The objective of the study was to evaluate and summarize the evidence from systematic reviews and meta-analyses regarding the efficacy and safety of Aidi injection combined with chemotherapy in the treatment of cancer patients. PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chong qing VIP databases, and Wanfang databases were searched for systematic reviews/meta-analyses on the topic of Aidi treating cancer patients published from inception to 20 December 2020. Google Scholar and OpenGrey were searched for grey literature and International Prospective Register of Systematic Reviews for ongoing reviews. Two investigators independently selected eligible studies, extracted data, and assessed the methodological quality of included systematic reviews/meta-analyses using the measurement tool to assess systematic reviews 2 (AMSTAR-2) tool, and the strength of evidence was assessed with the grade of recommendation, assessment, development, and evaluation (GRADE) system. Twenty-seven systematic reviews/meta-analyses were identified in the study. The methodological quality of all 27 systematic reviews/meta-analyses were critically low when evaluated by AMSTAR-2, and the evidence quality of all outcomes rated as either low or very low based on the GRADE system. The available evidence is currently insufficient to support or refute the use of Aidi in the treatment of cancer patients, thus high-quality trials with large sample sizes are needed to explore its efficacy and safety in cancer patients.

Integrative Management of Pancreatic Cancer (PDAC): Emerging Complementary Agents and Modalities

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease. The standard first-line treatment for PDAC is gemcitabine chemotherapy which, unfortunately, offers only limited chance of a lasting cure. This review further evaluates the hypothesis that the effectiveness of gemcitabine can be improved by combining it with evidence-based complementary measures. Previously, supported by clinical trial data, we suggested that a number of dietary factors and nutraceuticals can be integrated with gemcitabine therapy. Here, we evaluate a further 10 agents for which no clinical trials have (yet) been carried out but there are promising data from in vivo and/or in vitro studies including experiments involving combined treatments with gemcitabine. Two groups of complementary agents are considered: Dietary factors (resveratrol, epigallocatechin gallate, vitamin B9, capsaicin, quercetin and sulforaphane) and nutraceutical agents (artemisinin, garcinol, thymoquinone and emodin). In addition, we identified seven promising agents for which there is currently only basic (mostly in vitro) data. Finally, as a special case of combination therapy, we highlighted synergistic drug combinations involving gemcitabine with "repurposed" aspirin or metformin. We conclude overall that integrated management of PDAC currently is likely to produce the best outcome for patients and for this a wide range of complementary measures is available.

Comprehensive TCM treatments combined with chemotherapy for advanced non-small cell lung cancer: A randomized, controlled trial

OBJECTIVE

We conducted this study to evaluate the efficacy and safety of traditional Chinese medicine (TCM) in advanced non-small cell lung cancer (NSCLC) patients who underwent chemotherapy.

DESIGN

This was a prospective, open-label, randomized controlled trial. NSCLC patients at stage IIIA, IIIB, or IV were randomly assigned to either TCM plus chemotherapy or chemotherapy alone. The comprehensive TCM treatment consisted of Kang Ai injection, herbal decoction, and Zhenqifuzheng capsules. The primary endpoint was quality of life (QOL) measured by the Functional Assessment of Cancer Therapy-Lung version 4.0. The secondary endpoints were chemotherapy completion rate, tumor response, and adverse events. All assessments were done at baseline, the third week, and the sixth week.

RESULTS

Thirty-nine participants were randomly assigned to the treatment group and 36 to the control group. The QOL scores were significantly improved in the treatment group compared with those of the control group in social well-being (cycle 1, P = .048; cycle 2, P = .015), emotional well-being (cycle 1, P = .047; cycle 2, P = 4.29E-05), and functional well-being (cycle 1, P = .030; cycle 2, P = .003), while the QOL scores in the above 3 domains declined in the control group (P < .05). Both groups had a decline in the physical well-being score (cycle 1, P = .042; cycle 2, P = .017) and lung cancer symptom score (cycle 1, P = .001; cycle 2, P = .001) after 2 courses of intervention. The deterioration in physical well-being and lung cancer symptoms was noticeably smaller in the treatment group (P < .05). There were significant differences between the 2 groups in social well-being, emotional well-being, functional well-being, lung cancer symptom domain, and the total score (P < .05). Patients in the treatment group had a significantly lower incidence of platelet reduction than the control group (P = .028) after 2 cycles of treatment. No significant difference in nonhematological adverse events (AEs) was observed.

CONCLUSION

This study illustrated that comprehensive TCM treatment could promote the QOL of NSCLC patients, alleviate symptoms, and reduce the AEs caused by chemotherapy, verifying the synergistic and attenuating effects of TCM in NSCLC patients undergoing chemotherapy.

Prevention and treatment of digestive tract issues induced by postoperative adjuvant chemotherapy for pancreatic cancer using Terra Flava Usta

OBJECTIVE

To investigate the effects and possible mechanism of prevention and treatment of digestive tract reactions to postoperative adjuvant chemotherapy for pancreatic cancer (PC) using terra flava usta.

METHODS

A total of 75 PC patients with postoperative adjuvant chemotherapy who were admitted to our hospital from July 2016 to August 2019 were selected and randomly divided into a control group (CG) (n=37) and an observation group (OG) (n=38). Thirty min before chemotherapy, the CG received 8 mg of ondansetron via an intravenous drip, while the OG received 8 mg of ondansetron via an intravenous drip and terra flava usta. The grades of acute nausea and vomiting and delayed nausea and vomiting were compared between the two groups. The levels of gastrin (GAS), motilin (MTL), vasoactive peptide (VIP), hemoglobin (Hb), prealbumin (PA), and albumin (ALB), the proportion of CD4⁺, CD8⁺ and NK cells in T cell subsets, and the levels of 5-hydroxytryptamine (5-HT) and substance P (SP) were compared between the two groups.

RESULTS

The grades of delayed nausea and vomiting in the OG were superior to those in the CG (P < 0.05). The OG had higher levels of GAS and MTL and lower level of VIP than the CG after chemotherapy (P < 0.05). After chemotherapy, the levels of Hb, PA and ALB in the OG were higher than those in the CG (P < 0.05). After chemotherapy, the proportion of CD4⁺ and NK cells in the OG were higher than those in the CG, while the proportion of CD8⁺ in the OG was lower than that in the CG (P < 0.05). The serum 5-HT level in the acute phase and the delayed phase was higher than that before chemotherapy (P < 0.05), and the serum 5-HT level in the delayed phase was lower than that in the acute phase (P < 0.05). There was no significant difference in serum 5-HT level between the two groups in the acute phase and the delayed phase (P > 0.05). Compared with that before chemotherapy, SP levels in the OG decreased in the acute phase and the delayed phase, while SP levels in the CG did not change significantly, and SP levels in the OG were lower than those in the CG (P < 0.05).

CONCLUSION

Terra flava usta can effectively prevent and treat digestive tract reactions (e.g., delayed nausea and vomiting) induced by postoperative adjuvant chemotherapy for PC and protect gastrointestinal function, nutritional status and immune functions of PC patients. The mechanism of prevention and treatment of delayed digestive tract reactions after chemotherapy with terra flava usta may be related to the regulation of SP content. Therefore, terra flava usta is worthy of promotion and implementation.

Investigation on the Efficiency of Tonic Chinese Herbal Injections for Treating Dilated Cardiomyopathy Based on Bayesian Network Meta-Analysis

Introduction

This network meta-analysis investigated the efficacy of six tonic Chinese herbal injections (Huangqi injection, Shenfu injection, Shengmai injection, Shenmai injection, Shenqi Fuzheng injection, and Yiqifumai injection) compared to Western medicine for the treatment of the deteriorating state associated with dilated cardiomyopathy.

Methods

PubMed, the Cochrane Library, Embase, the Chinese Biological Medicine Database, China National Knowledge Infrastructure, the Wanfang Database, and the Chinese Scientific Journal Database were searched from their inception to October 15, 2020, to retrieve randomized controlled trials (RCTs). Study selection and data extraction conformed to a priori criteria. The risk of bias of the included RCTs was determined, and GRADE was used to evaluate outcomes. The network meta-analysis was calculated using WinBUGS 1.4.3 and Stata 13.0 software. The clinical effective rate, left ventricular ejection fraction, 6-minute walk test, left ventricular end-diastolic dimension, heart rate, and cardiac output were deemed outcomes. All outcomes were summarized as odds ratios or mean differences with their 95% credible intervals. The ranking probability of the interventions across various outcomes was also presented.

Results

Forty RCTs and 2970 patients were enrolled. Integration of the outcome results revealed that a combination of Shenfu injection and Western medicine ranked ahead of the other injections in most outcomes, especially in the clinical effective rate (OR = 0.21, 95% CI: 0.12–0.34), left ventricular ejection fraction (MD = 7.43, 95% CI: 2.41–12.38), and 6-minute walk test (MD = 50.39, 95% CI: 25.78–76.33). Shenmai injection plus Western medicine ranked ahead of the other injections in left ventricular end-diastolic dimension (69.5%) and cardiac output (60.9%). The cluster analysis suggested that Shenfu injection plus Western medicine was the most effective intervention for dilated cardiomyopathy.

Conclusions

Shenfu injection plus Western medicine may be a preferable treatment in dilated cardiomyopathy. Clinicians should also consider the specific patient's various conditions when making diagnostic decisions. Due to an insufficient network meta-analysis, more high-quality RCTs need to be implemented to support our conclusions.

Haimufang decoction, a Chinese medicine formula for lung cancer, arrests cell cycle, stimulates apoptosis in NCI-H1975 cells, and induces M1 polarization in RAW 264.7 macrophage cells

BACKGROUND

Lung cancer has the highest morbidity and mortality in the world and novel treatment strategies are still needed. Haimufang decoction (HMF) is a patented clinical prescription of traditional Chinese medicine for lung cancer treatment. HMF is composed of four herbs and has been applied clinically in advanced cancer patients. However, its therapeutic mechanisms are still unclear. This study aims to elucidate the possible mechanisms of HMF for the treatment of lung cancer.

METHODS

3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay was applied for evaluating the proliferative effect of HMF in lung cancer cells and monocyte macrophage RAW264.7 cells. Flow cytometer was used to detect the effects of HMF on cell cycle and apoptosis, and western blotting was employed to explore the potential apoptotic mechanisms of HMF on lung cancer cells. For immunomodulatory effect, co-culture system was used to detect the activation of macrophage RAW264.7 cells when treated with HMF, and neutral red assay was used to measure the effect of HMF on the phagocytosis of the activated macrophages. Enzyme linked immunosorbent assay, flow cytometer, and immunofluorescence staining method were employed for the investigation on the underlying mechanisms of the immunomodulatory effect on RAW264.7 induced by HMF.

RESULTS

HMF inhibited the proliferation, induced S phase cell cycle arrest, and stimulated apoptosis in lung cancer NCI-H1975 cells, while had negligible cytotoxicity on macrophage RAW264.7 cells. Moreover, HMF could activate macrophage RAW264.7 cells and promote the inhibition activity of RAW264.7 cells against lung cancer cells. And also, HMF activated macrophages and increased their phagocytic activity in a concentration-dependent manner. HMF increased the expression of macrophage activation marker CD40, the level of nitric oxide, the generation of intracellular reactive oxygen species, as well as M1 macrophages cytokines including tumor necrosis factor-α, interleukin-1β, interleukin 12 p70, and interleukin 6. Further investigation showed that HMF induced M1 but not M2 phenotype polarization in RAW264.7 cells.

CONCLUSIONS

HMF can mainly exert anticancer activity via (1) cytotoxicity to human lung cancer cells by proliferation inhibition, cell cycle arrest, and apoptosis induction; and also via (2) immunomodulation via macrophage cells activation and M1 phenotype polarization induction.

Matrine: A Promising Natural Product With Various Pharmacological Activities

Matrine is an alkaloid isolated from the traditional Chinese medicine Sophora flavescens Aiton. At present, a large number of studies have proved that matrine has an anticancer effect can inhibit cancer cell proliferation, arrest cell cycle, induce apoptosis, and inhibit cancer cell metastasis. It also has the effect of reversing anticancer drug resistance and reducing the toxicity of anticancer drugs. In addition, studies have reported that matrine has a therapeutic effect on Alzheimer's syndrome, encephalomyelitis, asthma, myocardial ischemia, rheumatoid arthritis, osteoporosis, and the like, and its mechanism is mainly related to the inhibition of inflammatory response and apoptosis. Its treatable disease spectrum spans multiple systems such as the nervous system, circulatory system, and immune system. The antidisease effect and mechanism of matrine are diverse, so it has high research value. This review summarizes recent studies on the pharmacological mechanism of matrine, with a view to providing reference for subsequent research.

A scoping review of network meta-analyses assessing the efficacy and safety of complementary and alternative medicine interventions

BACKGROUND

Network meta-analysis (NMA) has rapidly grown in use during the past decade for the comparison of healthcare interventions. While its general use in the comparison of conventional medicines has been studied previously, to our awareness, its use to assess complementary and alternative medicines (CAM) has not been studied. A scoping review of the literature was performed to identify systematic reviews incorporating NMAs involving one or more CAM interventions.

METHODS

An information specialist executed a multi-database search (e.g., MEDLINE, Embase, Cochrane), and two reviewers performed study selection and data collection. Information on publication characteristics, diseases studied, interventions compared, reporting transparency, outcomes assessed, and other parameters were extracted from each review.

RESULTS

A total of 89 SR/NMAs were included. The largest number of NMAs was conducted in China (39.3%), followed by the United Kingdom (12.4%) and the United States (9.0%). Reviews were published between 2010 and 2018, with the majority published between 2015 and 2018. More than 90 different CAM therapies appeared at least once, and the median number per NMA was 2 (IQR 1-4); 20.2% of reviews consisted of only CAM therapies. Dietary supplements (51.1%) and vitamins and minerals (42.2%) were the most commonly studied therapies, followed by electrical stimulation (31.1%), herbal medicines (24.4%), and acupuncture and related treatments (22.2%). A diverse set of conditions was identified, the most common being various forms of cancer (11.1%), osteoarthritis of the hip/knee (7.8%), and depression (5.9%). Most reviews adequately addressed a majority of the PRISMA NMA extension items; however, there were limitations in indication of an existing review protocol, exploration of network geometry, and exploration of risk of bias across studies, such as publication bias.

CONCLUSION

The use of NMA to assess the effectiveness of CAM interventions is growing rapidly. Efforts to identify priority topics for future CAM-related NMAs and to enhance methods for CAM comparisons with conventional medicine are needed.

Kanglaite injection plus fluorouracil-based chemotherapy on the reduction of adverse effects and improvement of clinical effectiveness in patients with advanced malignant tumors of the digestive tract: A meta-analysis of 20 RCTs following the PRISMA guidelines

BACKGROUND

The digestive tract malignancies are a series of malignant tumor with high morbidity and mortality. Traditional Chinese medicine (TCM) combined with chemotherapy drugs interventions have been applied for the treatment of malignant tumors in Asian countries for dacades. This study aimed to assess the effectiveness and safety on the combination of Kanglaite injection and fluorouracil-based chemotherapy for treating digestive tract malignancies.

PURPOSE

To assess the effectiveness and safety on the combination of Kanglaite injection and fluorouracil-based chemotherapy for digestive tract malignancies.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed when conducting the meta-analysis. Randomized controlled trials (RCTs) of Kanglaite injection combined with fluorouracil-based chemotherapy in the treatment of digestive tract malignant tumors were selected and assessed for inclusion. RevMan 5.3 software (Cochrane Collaboration, Oxford, UK) was used for meta-analysis. The objective response rate (ORR) was defined as the primary endpoint, and the disease control rate (DCR), quality of life (QoL), and toxicities were the secondary outcomes.

RESULTS

20 RCTs enrolling 1339 patients with advanced digestive tract malignancies were included. The methodological quality of most included trials was low to moderate. Compared with fluorouracil-based chemotherapy alone, Kanglaite injection plus fluorouracil-based chemotherapy can improve DCR (risk ratio (RR) = 1.18, 95% confidence interval (CI) 1.11-1.25, P < .00001), ORR (RR = 1.35, 95% CI 1.18-1.54, P < .00001), QoL (RR = 1.58, 95% CI 1.35-1.85, P < .00001), and can reduce adverse drug reactions (ADRs) such as myelosuppression (RR = 0.33, 95% CI 0.25-0.43, P < .00001), leukopenia (RR = 0.31, 95% CI 0.22-0.43, P < .00001), thrombocytopenia (RR = 0.6, 95% CI 0.38-0.49, P = .03), neutropenia (RR = 0.26, 95% CI 0.12-0.55, P = .0005), anemia (RR = 0.41, 95% CI 0.23-0.75, P = .004), gastrointestinal reaction (RR = 0.35, 95% CI 0.27-0.46, P < .00001), nausea/vomiting (RR = 0.41, 95% CI 0.28-0.61, P < .00001), diarrhea (RR = 0.34, 95% CI 0.18-0.62, P = .0004), hepatotoxicity (RR = 0.28, 95% CI 0.17-0.47, P < .00001), neurotoxicity (RR = 0.58, 95% CI 0.41-0.82, P = .002), mucositis (RR = 0.59, 95% CI 0.29-1.21, P = .15).

CONCLUSION

Kanglaite injection combined with fluorouracil-based chemotherapy could remarkably improve the clinical effectiveness and reduce the adverse effects in patients with advanced malignant tumors of the digestive tract which may provide evidence to judge whether TCM is an effective and safe intervention for the digestive tract malignancies.

Huayu Pill () Promotes Fluorescent Doxorubicin Delivery to Tumors in Mouse Model of Lung Cancer

OBJECTIVE

To study the effect and mechanism of Huayu Wan (, HYW) in combination of chemotherapy of tumor treatment.

METHODS

HYW serum was added in Lewis cells to assess its impact on fluorescent doxorubicin delivery in vitro. Then, Lewis tumor cells was implanted in C57BL/6 mice via xenograft transplantation. Tumor growth was measured and signal intensity corresponding to blood flow was assessed by laser doppler perfusion imaging (LDPI). Finally, the effect of HYW on the effificacy of doxorubicin was studied.

RESULTS

HYW can improve the transfer of fluorescent doxorubicin into cells. The blood flow signal in the tumor tissues of the HYW group was higher than that of the control group (P<0.01). Furthermore, HYW improved drug delivery of doxorubicin to tumor tissues, and this activity was associated with HYW-induced microvascular proliferation (P<0.01).

CONCLUSIONS

HYW can promote microangiogenesis and increase blood supply in tumor tissues, which in turn may increase the risk of metastasis. At the same time, HYW increases drug delivery and improves the effificacy of chemotherapy drugs through vascular proliferation. Therefore, rational judgment must be exercised when considering applying HYW to an antitumor regimen.

Clinical efficacy and safety of aidi injection combination with vinorelbine and cisplatin for advanced non-small-cell lung carcinoma: A systematic review and meta-analysis of 54 randomized controlled trials

The Aidi injection contains multiple active ingredients, including astragaloside (Re, Rb1, and Rg1), ginsenoside, cantharidin, elentheroside E, and syringin, and it is administered with vinorelbine and cisplatin (NP) to treat non-small-cell lung carcinoma (NSCLC). In this study, we performed a systematic review and meta-analysis to determine the clinical efficacy and safety of the Aidi injection with NP, and the optimal threshold and treatment regimen to produce the desired responses. We collected all studies regarding the Aidi injection with NP for NSCLC from Chinese and English databases (up to April 2019). Risk of methodological bias was evaluated for each study. Data for analysis were extracted using a standard data extraction form. Evidence quality was assessed following the Grading of Recommendations Assessment, Development and Evaluation approach. We included 54 trials containing 4,053 patients for analysis. Combining the Aidi injection with NP significantly increased the objective response rate (odds ratio [OR], 1.32; confidence interval [CI], 1.23, 1.42), disease control rate (OR, 1.14; CI, 1.11, 1.18), and quality of life (OR, 1.80; CI, 1.61, 1.98), with decreased risks of myelosuppression, neutropenia, thrombocytopenia, anemia, gastrointestinal reaction, and liver dysfunction. For patients with a Karnofsky Performance Status score of ≥60, the Aidi injection (50 mL/day, two weeks/cycle, with two to three cycles) treatment with vinorelbine (25 mg/m²) and cisplatin (30-35 mg/m² or 40-50 mg/m²) might be the optimal regimen for producing the desired tumor response and achieving a good safety level. Most results were robust, and their quality was moderate. The results suggest that administration of the Aidi injection and concomitant NP is beneficial to NSCLC, and provide evidence for the optimal threshold and treatment regimen that may improve tumor response with a good safety level.

Coix Seed Extract Enhances the Anti-Pancreatic Cancer Efficacy of Gemcitabine through Regulating ABCB1- and ABCG2-Mediated Drug Efflux: A Bioluminescent Pharmacokinetic and Pharmacodynamic Study

A deep insight into the function and kinetics of ATP-binding cassette (ABC) transporters may aid in the development of pharmaceutics that can minimize the particular facet of chemo-resistance. We utilized bioluminescence imaging to monitor the ABC transporter mediated intracellular drug efflux function. We also investigated the potential association between the intracellular bioluminescent pharmacokinetic profiles and the anti-tumor efficacy of the coix seed extract and gemcitabine against pancreatic cancer cells in vitro and in vivo. The bioluminescent pharmacokinetic parameters and pharmacodynamic index (IC₅₀ and TGI) were determined. The expression levels ABCB1 and ABCG2 were assessed. Results showed that coix seed extract could synergistically enhance the anti-cancer efficacy of gemcitabine (p < 0.05). Meanwhile coix seed extract alone or in combination with gemcitabine could significantly increase the AUC_luc while decreasing the K_luc (p < 0.01). Western blot and immunohistochemistry assay demonstrated that coix seed extract could significantly mitigate gemcitabine-induced upregulation of ABCB1 and ABCG2 protein. The Pearson correlation analysis demonstrated that the bioluminescent pharmacokinetic parameters and pharmacodynamic index have strong association in vitro and in vivo. In conclusion coix seed extract could augment the efficacy of gemcitabine therapy in pancreatic cancer cells may at least partly due to the alteration of ABC transporter-mediated drug efflux function.

Comparative efficacy of Chinese herbal injections combined with azithromycin for mycoplasma pneumonia in children: A Bayesian network meta-analysis of randomized controlled trials

WHAT IS KNOWN AND OBJECTIVE

An increasing macrolide resistance leads to complex clinical treatment schemes in mycoplasma pneumonia in children. Chinese herbal injection (CHI) is widely used to treat it and may provide a new treatment regimen. This study was conducted to systematically evaluate the efficacy of CHIs combined with azithromycin for treating mycoplasma pneumonia in children by Bayesian network meta-analysis.

METHODS

Randomized controlled trials (RCTs) of CHIs combined with azithromycin for mycoplasma pneumonia in children were searched in electronic databases and related references from initiation to 30 October 2018. Two researchers conducted data extraction and risk of bias assessment. WinBUGS software and STATA software were adopted to analyse the data.

RESULTS

A total of 167 RCTs were included with 5 CHIs involving 16 144 patients. All CHIs combined with azithromycin had superior effects than azithromycin only among overall outcomes. Yanhuning injection combined with azithromycin ranked highest in four different outcomes and second in two based on surface under the cumulative ranking probabilities (SUCRA). Meanwhile, the results of MD and 95% CIs of concerned outcomes indicated that only Yanhuning injection combined with azithromycin had better response than other CHIs combined with azithromycin. Moreover, cluster analysis results revealed Reduning injection combined with azithromycin was associated with a positive effect on the three group outcomes. Similarly, it was found to be the top three ranking in all outcomes based on SUCRA.

WHAT IS NEW AND CONCLUSION

Yanhuning injection combined with azithromycin and Reduning injection combined with azithromycin were found to be preferable treatments based on the data of this study.

Apoptotic Pathway as the Therapeutic Target for Anticancer Traditional Chinese Medicines

Cancer is a leading cause of morbidity and mortality worldwide. Apoptosis is a process of programmed cell death and it plays a vital role in human development and tissue homeostasis. Mounting evidence indicates that apoptosis is closely related to the survival of cancer and it has emerged as a key target for the discovery and development of novel anticancer drugs. Various studies indicate that targeting the apoptotic signaling pathway by anticancer drugs is an important mechanism in cancer therapy. Therefore, numerous novel anticancer agents have been discovered and developed from traditional Chinese medicines (TCMs) by targeting the cellular apoptotic pathway of cancer cells and shown clinically beneficial effects in cancer therapy. This review aims to provide a comprehensive discussion for the role, pharmacology, related biology, and possible mechanism(s) of a number of important anticancer TCMs and their derivatives mainly targeting the cellular apoptotic pathway. It may have important clinical implications in cancer therapy.

Traditional Chinese Medicine Preparation Combined Therapy May Improve Chemotherapy Efficacy: A Systematic Review and Meta-Analysis

Background

Whether traditional Chinese medicine preparation combined therapy can improve the efficacy of chemotherapy is controversial. This meta-analysis evaluates the efficacy of traditional Chinese medicine preparation combined with chemotherapy.

Method

Three databases were searched from inception through August 2018. Eligible randomized controlled trials (RCTs) involving the combined treatment of chemotherapy and traditional Chinese medicine preparation compared to chemotherapy alone for treating cancer were retrieved. The methodological quality of the included RCTs was assessed with Cochrane Collaboration's risk of bias assessment tool. Meta-analysis was adopted to make comprehensive comparisons between the experimental and control groups.

Results

Four RCTs were included in this review, comprising 256 subjects. The majority of the RCTs were judged as being of poor methodological quality. Meta-analysis showed that the combination of traditional Chinese medicine preparation and chemotherapy appeared to be more effective than chemotherapy alone, for the treatment of cancer, as assessed by the disease control rate (RR: 1.41, 95% CI: 1.11 to 1.79) and the objective response rate (RR: 2.71, 95% CI: 1.28 to 5.77). There were no statistically significant differences between the groups in terms of bone marrow suppression (RR: 0.88, 95% CI: 0.57 to 1.37) or gastrointestinal reaction (RR: 1.12, 95% CI 0.75 to 1.69).

Conclusions

Traditional Chinese medicine preparation combined with chemotherapy may improve objective response rates and disease control rates more than chemotherapy alone. The evidence that combined traditional Chinese medicine preparation can reduce the side effects of chemotherapy is insufficient. More rigorous randomized controlled trials are needed to confirm these conclusions.

Network Meta-Analysis of Chinese Herbal Injections Plus the FOLFOX Regimen for the Treatment of Colorectal Cancer in China

OBJECTIVE

The aim of the present network meta-analysis (NMA) was to explore the comparative effectiveness and safety of different Chinese herbal injections (CHIs) combined with the FOLFOX regimen versus FOLFOX alone for colorectal cancer (CRC).

METHODS

A comprehensive search for randomized controlled trials (RCTs) was performed with regard to different CHIs for treating CRC in several electronic databases up to July 2016. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Standard pair-wise and Bayesian NMA were designed to compare the effectiveness and safety of different CHIs combined with the FOLFOX regimen by utilizing WinBUGS 1.4.3 and Stata 13.1 software, simultaneously.

RESULTS

Initially, a total of 820 citations were retrieved through comprehensive searching, and 60 eligible articles involving 4849 participants and 14 CHIs were ultimately included. The results of the current evidence indicated that the FOLFOX regimen combined with Delisheng, Kanglaite, Shenqifuzheng, or Aidi injections were associated with the most favorable clinical efficacy compared with the FOLFOX regimen alone. Additionally, the FOLFOX regimen combined with Delisheng, Xiaoaiping, Lentinan, Kangai, Shenqifuzheng, or Aidi injections improved performance status among patients with CRC.

CONCLUSIONS

The results of cluster analysis demonstrated that the combination of Compound matrine injection and FOLFOX regimen was associated with more preferable and beneficial outcomes than other CHIs groups. Nevertheless, the additional results from multicenter trials and high-quality studies will be pivotal for supporting our findings.

Efficacy and safety of compound Kushen injection combined with chemotherapy on postoperative Patients with breast cancer: A meta-analysis of randomized controlled trials

BACKGROUND

This meta-analysis aimed to assess efficacy and safety of combination of Kushen and chemotherapy or chemotherapy alone among postoperative patients with breast cancer receiving.

METHODS

A systematic literature search was conducted for relevant randomized controlled trials from 2000 to July 2017. Primary outcomes were clinical response rate (CRR) and performance status improvement by Karnofsky performance scale score (KPSS); secondary outcomes were adverse drug reactions (ADRs) rate and tumor marker decrease rate. Quality assessment and data analysis were performed with Review Manager 5.3.

RESULTS

A total of 16 studies with 1315 participants were included in the analysis. Compared with chemotherapy alone, compound Kushen injection (CKI or KI) combined with chemotherapy did not significant increase CRR. However, performance status improvement rate was significantly higher among patients given Kushen injection combined with chemotherapy (relative risk 1.25, 95% confidence interval 1.09-1.42, P = .001). In the analysis of ADRs, combination of Kushen and chemotherapy was indicated to significantly reduce the rate liver dysfunction, kidney dysfunction, nausea and vomiting, diarrhea, hair loss, platelet decrease, and oral mucositis.

CONCLUSION

Using CKI on the basis of chemotherapy might improve performance status and reduce ADRs among postoperative patients with breast cancer.

Shenqi Fuzheng Injection in the Treatment of Breast Cancer: A Meta-analysis of Randomized Controlled Trials

OBJECTIVE

This meta-analysis synthesized the available evidence on the effectiveness and safety of Shenqi Fuzheng injection (SQFZI) combined with chemotherapy for breast cancer.

METHOD

A comprehensive systematic literature search was conducted to identify the randomized controlled trials (RCTs) on breast cancer treated by SQFZI in several electronic database up to October 29, 2017. The included RCTs were assessed using the Cochrane Collaboration tool; data were extracted and analyzed via RevMan 5.3 and Stata 13.0 software.

RESULTS

A total of 31 eligible RCTs comprising 2543 participants were selected in this present meta-analysis. The results demonstrated that compared with receiving conventional chemotherapy alone, SQFZI treatment combined with chemotherapy was more efficient in improving clinical total effective rate (relative risk [RR] = 1.31, 95% CI 1.19-1.44, P < .00001) and performance status (RR = 2.23, 95% CI 1.88-2.65, P < .00001). Additionally, SQFZI combined with chemotherapy was capable of enhancing immune function and alleviating adverse drug reactions for patients with breast cancer.

CONCLUSIONS

The current evidence suggested that using SQFZI as an adjunct treatment to chemotherapy may be preferable for patients with breast cancer compared to chemotherapy alone. Because of the limitations of the quantities and qualities of included RCTs, more well-designed RCTs are needed to further support our conclusion.

Aidi Injection, a Traditional Chinese Medicine Injection, Could Be Used as an Adjuvant Drug to Improve Quality of Life of Cancer Patients Receiving Chemotherapy: A Propensity Score Matching Analysis

Background: Clinical research has paid increasing attention to quality of life (QoL) in recent years, but the assessment of QoL is difficult, hampered by the subjectivity, complexity, and adherence of patients and physicians. According to previous studies, QoL in cancer patients is related to performance status (PS) and influenced by chemotherapy-related toxicity. Aidi injection, a traditional Chinese medicine injection, is used as an adjuvant drug to enhance effectiveness of chemotherapy. The study aims to investigate whether Aidi injection could improve QoL by improving PS and reducing toxicity caused by chemotherapy. Methods: A retrospective cohort study was performed at the First Affiliated Hospital of Anhui Medicine University. Data of consecutive patients diagnosed with cancers between January 2014 and June 2017 were retrieved from the electronic medical record system. After a 1:1 propensity score match, patients were then divided into 2 groups based on the therapies used, that is, Aidi injection combined with chemotherapy and chemotherapy alone, and the PS, chemotherapy-related toxicity, and combined medication information were compared. The effect of different dosages of Aidi injection on patients was further explored. Results: A total of 3200 patients were included in this study. Aidi injection combined with chemotherapy exhibited significantly benefit in PS (P < .001, odds ratio [OR] 3.4, 95% confidence interval [CI] 2.4-4.8) compared with chemotherapy alone after adjusting for the factors that affect PS. The improvement rate of PS in the Aidi group was significantly higher than in the control group across the stratification of gender, age, tumor type, TNM stage, body mass index, nodal metastasis, prior chemotherapy, chemotherapy regimens, other Chinese tradition medicines, and chemotherapy cycle. Meanwhile, Aidi injection used synchronously with chemotherapeutic drugs could decrease the incident rate of damage to liver and kidney function, myelosuppression, and gastrointestinal reactions caused by chemotherapy. Conclusion: It was indicated that the integrative approach combining chemotherapy with Aidi injection, especially with the conventional dosage of Aidi injection, had significant benefit on QoL in cancer patients.

Assessing the methodological and reporting quality of network meta-analyses in Chinese medicine

BACKGROUND

An increasing number of network meta-analyses (NMAs) in traditional Chinese medicine (TCM) have been published recently, but the quality of them was lack of assessment. This study aims to evaluate the methodological and reporting quality of NMAs in TCM.

METHODS

Six electronic databases, including PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, China National Knowledge Infrastructure (CNKI), Wanfang and Chinese Biomedical Literature Database (CBM) from inception to January 2018, were searched. NMAs of TCM were included. A measurement tool to assess the methodological quality of systematic reviews (AMSTAR) and the PRISMA Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-analyses of Health Care Interventions (PRISMA-NMA) were used to assess the methodological and reporting quality of the included NMAs.

RESULTS

A total of 40 NMAs, including 2535 randomized controlled trials (RCTs), were included. They were published between December 2012 and November 2017. The median score and interquartile range of methodological and reporting quality was 7 (6-8) and 22 (19.1-27.1). Serious methodological flaws existed in the following aspects: the status of publication (22.5%), a list of studies provided (0%), assessment of publication bias (37.5%), and conflicts of interest (12.5%). Several items need to be improved in reporting, especially for Protocol and registration (2.5%), Data items (22.5%), Risk of bias across studies (Methods section) (37.5%), Results of individual studies (27.5%), Risk of bias across studies (Results section) (40%), Results of additional analyses (35%), and Funding (15%).

CONCLUSIONS

The methodological and reporting quality of NMAs in TCM is moderate. Identified shortcomings of published NMAs should be taken into consideration in further trainings of authors and editors of NMAs in TCM. Future researchers should be encouraged to apply PRISMA-NMA, and a recognized tool for the assessment of NMA methodology was wanted.

Chinese herbal injections for unstable angina pectoris: A protocol for systematic review and network meta-analyses

BACKGROUND

Chinese herbal injections (CHIs) have been commonly used in the treatment of unstable angina pectoris (UAP) in China. However, there is no consensus or evidence on how to select CHIs for patients with UAP. The choice often depends on the personal experience or preference of clinician. This study aims to compare the effect of different CHIs for UAP using Bayesian network meta-analysis (NMA).

METHODS

A systematic search will be conducted in PubMed, the Cochrane Central Register of Controlled Trials, Embase, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and Wanfang Data from inception to February 2018. We will include randomized controlled trials (RCT) regarding CHIs in the treatment of UAP. Quality of included RCTs will be assessed according to the Cochrane Handbook 5.1.0. A Bayesian NMA will be performed with WinBUGS 14 to compare the efficacy of different CHIs. GRADE will be used to assess the quality of evidence.

RESULTS

The results of this NMA will be submitted to a peer-reviewed journal for publication.

CONCLUSION

Our study will generate evidence for CHIs in the treatment of UAP and help clinicians make more accurate therapeutic schedule. In addition, it might provide suggestions for Chinese medicine clinical practice or guideline.

Comparative efficacy of Chinese herbal injections for treating chronic heart failure: a network meta-analysis

BACKGROUND

On account of deterioration of chronic heart failure (CHF) and extensive exploration of Chinese herbal injections (CHIs), we performed a network meta-analysis to investigate the efficacy of CHIs (Huangqi injection, Shenfu injection, Shengmai injection, Shenmai injection, Shenqi Fuzheng injection, Yiqifumai injection) on the basis of western medicine (WM) treatment in CHF.

METHODS

Literature search was conducted in Embase, the Cochrane Library, Pubmed, Chinese Biological Medicine Database, China National Knowledge Infrastructure, Wanfang Database, Chinese Scientific Journal Database from inception to June 12nd 2017, and study selection was abided by a prior eligible criteria.

RESULTS

Ultimately, a total of 113 randomized controlled trials (RCTs) were enrolled. The clinical data of the effective clinical rate, left ventricular ejection fraction, cardiac output and others outcomes was estimated by Stata software and Winbugs software. Risk of bias was assessed by Cochrane Collaboration's tools. Integrating the each outcome's results, a combination of Shengmai injection/Shenmai injection and WM obtain a first rank in most outcomes, particularly primary outcomes.

CONCLUSIONS

In conclusion, on the basis of WM, Shengmai injection or Shenmai injection may be a perforable treatment in CHF. In terms of insufficient of this study, more high quality RCTs needed to implement to support our conclusions.
