[PMID: 38380576 DOI: 10.1016/j.jep.2023.117364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 10/25/2023] [Accepted: 10/27/2023] [Indexed: 02/22/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese medicine, Artemisia argyi has been used medicinally and eaten for more than 2000 years in China. It is widely reported in treating inflammatory diseases such as eczema, dermatitis, arthritis, allergic asthma and colitis. Although several studies claim that its volatile oil and organic reagent extracts have certain anti-inflammatory effects, the water-soluble fractions and molecular mechanisms have not been studied. AIM OF THE STUDY To evaluate the therapeutic effect of A. argyi water extract (AAWE) on lipopolysaccharide (LPS)-induced inflammatory responses and to identify the most effective water-soluble subfractions. Moreover, the relevant pharmacological and molecular mechanisms by which the active subfraction mitigates inflammation were further investigated. MATERIALS AND METHODS Firstly, RAW 264.7 cells stimulated with LPS were treated with AAWE (50, 100, and 200 μg/mL) or the water-soluble subfractions separated by D101 macroporous resin (AAWE1-AAWE4, 100 μg/mL), and NO production and mRNA levels of inflammatory genes were evaluated to determine the most effective water-soluble subfractions. Secondly, the chemical components of the active subfraction (AAWE4) were analyzed by UPLC-QTOF-MS. Thirdly, transcriptome and network pharmacology analysis, RT-qPCR and Western blotting assays were conducted to explore the underlying anti-inflammatory mechanism and active compounds of AAWE4. Subsequently, the binding ability of the potential active components in AAWE4 to the core targets was further determined by molecular docking. Eventually, the in vivo anti-inflammatory activity of AAWE4 (1.17, 2.34 and 4.68 g/kg, administered per day for 7 d) was evaluated in mice with LPS-induced systemic inflammation. RESULTS In this study, AAWE showed excellent anti-inflammatory effects, and its water-soluble subfraction AAWE4 exhibited the strongest inhibitory effect on NO concentration and inflammatory gene mRNA expression after LPS stimulation, indicating that it was the most effective subfraction. Thereafter, four main compounds in AAWE4 were confirmed or tentatively identified by UPLC-QTOF-MS, including three flavonoid glycosides and one phenolic acid. Furthermore, the transcriptome and network pharmacology analysis showed that AAWE4 inhibited inflammation via multiple pathways and multiple targets. Based on the RT-qPCR and Western blotting results, AAWE4 downregulated not only the p38, PI3K, CCL5, MMP9, AP-1, and BCL3 mRNA expression levels activated by LPS but also their upstream and downstream protein expression levels and protein phosphorylation (p-AKT/AKT, p-p38/p38, p-ERK/ERK, p-JNK/JNK). Moreover, four identified compounds (isochlorogenic acid A, vicenin-2, schaftoside and isoschaftoside) could significantly inhibit NO content and the overexpression of inflammatory factors TNF-α, IL-1β, iNOS and COX-2 mRNA induced by LPS, and the molecular docking confirmed the high binding activity of four active compounds with selected core targets (p38, AKT1, MMP9, and CCL5). In addition, the mRNA expression and immunohistochemical analysis showed that AAWE44 could inhibit lung inflammation via multiple pathways and multiple targets in vivo. CONCLUSIONS The findings of this study suggest that the water-soluble subfraction AAWE4 from A. argyi ameliorated the inflammation caused by LPS through multiple pathways and multiple targets in vitro and in vivo, providing scientific support for the medicinal use of A. argyi. Importantly, it shows that the A. argyi subfraction AAWE4 can be developed as an anti-inflammatory drug.

Relationship among Chinese herb polysaccharide (CHP), gut microbiota, and chronic diarrhea and impact of CHP on chronic diarrhea. Food Sci Nutr 2023; 11:5837-5855. [PMID: 37823142 PMCID: PMC10563694 DOI: 10.1002/fsn3.3596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/13/2023] [Accepted: 07/22/2023] [Indexed: 10/13/2023] Open
Abstract
Chronic diarrhea, including diarrhea-predominant irritable bowel syndrome (IBS-D), osmotic diarrhea, bile acid diarrhea, and antibiotic-associated diarrhea, is a common problem which is highly associated with disorders of the gut microbiota composition such as small intestinal bacterial overgrowth (SIBO) and so on. A growing number of studies have supported the view that Chinese herbal formula alleviates the symptoms of diarrhea by modulating the fecal microbiota. Chinese herbal polysaccharides (CHPs) are natural polymers composed of monosaccharides that are widely found in Chinese herbs and function as important active ingredients. Commensal gut microbiota has an extensive capacity to utilize CHPs and play a vital role in degrading polysaccharides into short-chain fatty acids (SCFAs). Many CHPs, as prebiotics, have an antidiarrheal role to promote the growth of beneficial bacteria and inhibit the colonization of pathogenic bacteria. This review systematically summarizes the relationship among gut microbiota, chronic diarrhea, and CHPs as well as recent progress on the impacts of CHPs on the gut microbiota and recent advances on the possible role of CHPs in chronic diarrhea.

Kampo formula hochu-ekki-to (Bu-Zhong-Yi-Qi-Tang, TJ-41) ameliorates muscle atrophy by modulating atrogenes and AMPK in vivo and in vitro. BMC Complement Med Ther 2022; 22:341. [PMID: 36578084 PMCID: PMC9795672 DOI: 10.1186/s12906-022-03812-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 11/28/2022] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Muscle disuse results in loss of skeletal muscle mass and function. Hochu-ekki-to (TJ-41; Bu-Zhong-Yi-Qi-Tang in Chinese) is an herbal medicinal formulation used to treat patients with frailty, fatigue and appetite loss. It has been suggested that two atrogenes, atrogin-1 and muscle Ring finger 1 (MuRF1), are ubiquitin ligases involved in disuse-induced muscle atrophy and that 5' adenosine monophosphate-activated protein kinase (AMPK) is involved in skeletal muscle metabolism. Effects of TJ-41 on disuse-induced muscle atrophy are unclear. METHODS We subjected differentiated C2C12 myotubes to serum starvation, then examined the effects of TJ-41 on atrogenes expression, AMPK activity and the morphology of the myotubes. Male C57BL/6J mice were subjected to tail-suspension to induce hindlimb atrophy. We administered TJ-41 by gavage to the control group and the tail-suspended group, then examined the effects of TJ-41 on atrogene expression, AMPK activity, and the muscle weight. RESULTS Serum starvation induced the expression of atrogin-1 and MuRF1 in C2C12 myotubes, and TJ-41 significantly downregulated the expression of atrogin-1. Tail-suspension of the mice induced the expression of atrogin-1 and MuRF1 in skeletal muscle as well as its muscle atrophy, whereas TJ-41 treatment significantly downregulated the expression of atrogin-1 and ameliorated the loss of the muscle weight. In addition, TJ-41 also activated AMPK and inactivated Akt and mTOR in skeletal muscle in vivo. CONCLUSION TJ-41 inhibited atrogenes in an Akt-independent manner as well as activating AMPK in skeletal muscles in vivo, further implying the therapeutic potential of TJ-41 against disuse-induced muscle atrophy and other atrogenes-dependent atrophic conditions.

Experimental Chemotherapy-Induced Mucositis: A Scoping Review Guiding the Design of Suitable Preclinical Models. Int J Mol Sci 2022; 23:ijms232315434. [PMID: 36499758 PMCID: PMC9737148 DOI: 10.3390/ijms232315434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 12/01/2022] [Accepted: 12/04/2022] [Indexed: 12/12/2022] Open
Abstract
Mucositis is a common and most debilitating complication associated with the cytotoxicity of chemotherapy. The condition affects the entire alimentary canal from the mouth to the anus and has a significant clinical and economic impact. Although oral and intestinal mucositis can occur concurrently in the same individual, these conditions are often studied independently using organ-specific models that do not mimic human disease. Hence, the purpose of this scoping review was to provide a comprehensive yet systematic overview of the animal models that are utilised in the study of chemotherapy-induced mucositis. A search of PubMed/MEDLINE and Scopus databases was conducted to identify all relevant studies. Multiple phases of filtering were conducted, including deduplication, title/abstract screening, full-text screening, and data extraction. Studies were reported according to the updated Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. An inter-rater reliability test was conducted using Cohen's Kappa score. After title, abstract, and full-text screening, 251 articles met the inclusion criteria. Seven articles investigated both chemotherapy-induced intestinal and oral mucositis, 198 articles investigated chemotherapy-induced intestinal mucositis, and 46 studies investigated chemotherapy-induced oral mucositis. Among a total of 205 articles on chemotherapy-induced intestinal mucositis, 103 utilised 5-fluorouracil, 34 irinotecan, 16 platinum-based drugs, 33 methotrexate, and 32 other chemotherapeutic agents. Thirteen articles reported the use of a combination of 5-fluorouracil, irinotecan, platinum-based drugs, or methotrexate to induce intestinal mucositis. Among a total of 53 articles on chemotherapy-induced oral mucositis, 50 utilised 5-fluorouracil, 2 irinotecan, 2 methotrexate, 1 topotecan and 1 with other chemotherapeutic drugs. Three articles used a combination of these drugs to induce oral mucositis. Various animal models such as mice, rats, hamsters, piglets, rabbits, and zebrafish were used. The chemotherapeutic agents were introduced at various dosages via three routes of administration. Animals were mainly mice and rats. Unlike intestinal mucositis, most oral mucositis models combined mechanical or chemical irritation with chemotherapy. In conclusion, this extensive assessment of the literature revealed that there was a large variation among studies that reproduce oral and intestinal mucositis in animals. To assist with the design of a suitable preclinical model of chemotherapy-induced alimentary tract mucositis, animal types, routes of administration, dosages, and types of drugs were reported in this study. Further research is required to define an optimal protocol that improves the translatability of findings to humans.

Abstract
In order to provide evidence for clinical application, the therapeutic effect and mechanism of Huangqi Bazhen decoction on chemotherapeutic intestinal mucositis induced by capecitabine in mice are investigated. In this paper, the mice are divided into different groups and given capecitabine intragastric administration or treatment drugs. Morphological features of intestinal injury, including villus height shortening, crypt destruction, and apoptosis, are reversed. The experimental results show that Huangqi Bazhen decoction can significantly reduce weight loss and diarrhea during capecitabine treatment. It is also found that GSH-Px and T-SOD can be improved while MDA, IL-1β, and TNF-α are reduced significantly.

Abstract
Parents often have concerns regarding anorexia in their children and visiting medical institutions for the intervention of it. This study aimed to investigate the clinical practice patterns of Korean medicine doctors (KMDs) for anorexia in children using a web-based survey. A link to the questionnaire was sent via email to all KMDs that were affiliated with the Association of Korean Medicine. The questionnaire covered items on the sociodemographic characteristics and clinical characteristics related to Korean medicine (KM), such as diagnosis, treatment, awareness, safety, and effectiveness. Of 23,910 KMDs, 384 agreed to participate and complete the questionnaire. Anorexia in children was diagnosed mainly by clinical features (36.4%) and the pattern identification (PI) theory of ‘Qi, Blood, Fluid, Humor, and Organ system diagnoses’ (32.8%). The most frequently used PIs was ‘spleen-stomach qi deficiency’ (38.6%), which was followed by ‘spleen failure in transportation’ (23.3%), ‘stomach yin deficiency’ (15.5%), and ‘liver depression’ (14.2%). Herbal medicine (38.1%) was the primary KM treatment for anorexia, and the names of the most frequently prescribed herbal decoctions were Sogunjung-tang (16.5%), Hyangsayukgunja-tang (15.9%), and Bojungikgi-tang (13.9%). This study provides information on the existing clinical practice patterns of KMDs for anorexia in children. Based on this survey, the clinical practice guidelines will be developed.

Abstract
Cancers represent a significant cause of morbidity and mortality worldwide. They also impose a large economic burden on patients, their families, and health insurance systems. Notably, cancers and the adverse reactions to their therapeutic options, chemotherapy and radiotherapy, dramatically affect the quality of life of afflicted patients. Therefore, developing approaches to manage chemotherapy- and radiotherapy-induced adverse reactions gained greater attention in recent years. Glycyrrhiza glabra (licorice), a perennial plant that is one of the most frequently used herbs in traditional Chinese medicine, has been heavily investigated in relation to cancer therapy. Licorice/licorice-related regimes, used in combination with chemotherapy, may improve the adverse effects of chemotherapy. However, there is little awareness of licorice-containing herbs alleviating reactions to radiotherapy and chemotherapy, or to other induced adverse reactions in cancer treatment. We aimed to provide a descriptive review, and to emphasize the possibility that licorice-related medicines could be used as an adjuvant regimen with chemotherapy to improve quality of life (QoL) and to reduce side effects, thus, improving compliance with chemotherapy. The experimental method involved searching different databases, including PubMed, the Cochrane Library, and Wang Fang database, as of May 2022, to identify any relevant studies. Despite a lack of high-quality and large-scale randomized controlled trials, we still discovered the potential benefits of licorice-containing herbs from published clinical studies. These studies find that licorice-containing herbs, and their active ingredients, reduce the adverse reactions caused by chemotherapy and radiotherapy, and improve the QoL of patients. This comprehensive review will serve as a cornerstone to encourage more scientists to evaluate and develop effective Traditional Chinese medicine prescriptions to improve the side effects of chemotherapy and radiation therapy.

Traditional Herbal Medicine: A Potential Therapeutic Approach for Adjuvant Treatment of Non-small Cell Lung Cancer in the Future. Integr Cancer Ther 2022; 21:15347354221144312. [PMID: 36567455 PMCID: PMC9806388 DOI: 10.1177/15347354221144312] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 11/17/2022] [Accepted: 11/23/2022] [Indexed: 12/27/2022] Open
Abstract
Lung carcinoma is the primary reason for cancer-associated mortality, and it exhibits the highest mortality and incidence in developed and developing countries. Non-small cell lung cancer (NSCLC) and SCLC are the 2 main types of lung cancer, with NSCLC contributing to 85% of all lung carcinoma cases. Conventional treatment mainly involves surgery, chemoradiotherapy, and immunotherapy, but has a dismal prognosis for many patients. Therefore, identifying an effective adjuvant therapy is urgent. Historically, traditional herbal medicine has been an essential part of complementary and alternative medicine, due to its numerous targets, few side effects and substantial therapeutic benefits. In China and other East Asian countries, traditional herbal medicine is increasingly popular, and is highly accepted by patients as a clinical adjuvant therapy. Numerous studies have reported that herbal extracts and prescription medications are effective at combating tumors. It emphasizes that, by mainly regulating the P13K/AKT signaling pathway, the Wnt signaling pathway, and the NF-κB signaling pathway, herbal medicine induces apoptosis and inhibits the proliferation and migration of tumor cells. The present review discusses the anti-NSCLC mechanisms of herbal medicines and provides options for future adjuvant therapy in patients with NSCLC.

Abstract
Purpose To determine the potentials of Hochuekkito (HET) treatment for aging infertility. Methods Mice at 36 weeks of age were fed without (control, n = 40) or with low (100 mg/kg/day, n = 24) and high (1000 mg/kg/day, n = 38) doses of HET for 12 weeks. Aging animals at 48 weeks of age were used for in vitro fertilization-embryo transfer (IVF-ET), and their ovaries were subjected to histological and quantitative inflammation analyses. Results HET administration decreased transcript levels of ovarian inflammatory markers, interleukin 6 (IL-6), IL-1β, tumor necrosis factor (TNF)-α, and interferon-gamma (IFN-γ) but suppressed ovulation rates and the number of ovulated oocytes in aging mice. Furthermore, HET treatment decreased the rates of oocytes maturation and fertilization and the cumulus-cell expression of TNF-α-induced protein 6 and epidermal growth factor receptor. After IVF-ET, no improvement of declined live offspring rate by aging was achieved by HET administration, although there were no adverse effects on embryo development and implantation as well as gross morphology and bodyweight of pups. Conclusion Present study indicated HET treatment interfered with ovulation and fertilization in aging mice without affecting ovarian follicle development. No improvement on the age-associated decline of live offspring rate and follicle development was achieved after HET treatment.

Berberine Improves Irinotecan-Induced Intestinal Mucositis Without Impairing the Anti-colorectal Cancer Efficacy of Irinotecan by Inhibiting Bacterial β-glucuronidase. Front Pharmacol 2021; 12:774560.

Abstract
Irinotecan (CPT11), a broad-spectrum cytotoxic anticancer agent, induces a series of toxic side-effects. The most conspicuous side-effect is gastrointestinal mucositis, including nausea, vomiting, and diarrhea. A growing body of evidence indicates that bacteria β-glucuronidase (GUS), an enzyme expressed by intestinal microbiota, converts the inactive CPT11 metabolite SN38G to the active metabolite SN38 to ultimately induce intestinal mucositis. We sought to explore the potential efficacy and underlying mechanisms of berberine on CPT11-induced mucositis. Our study showed that berberine (50 mg/kg; i. g.) mitigated the CPT11-induced loss of mucosal architecture, ulceration, and neutrophil infiltration. Meanwhile, berberine improved mucosal barrier function by increasing the number of globlet cells, protecting trans-endothelial electrical resistance (TEER), reducing permeability and increasing tight junction proteins expression. LC-MS analysis showed that berberine decreased the content of SN38 in feces, which correlated with decreases in both GUS activity and GUS-producing bacteria. Further molecular docking and Lineweaver-Burk plots analyses suggested that berberine functions as a potential non-competitive inhibitor against GUS enzyme. Of note, berberine maintained the anti-tumor efficacy of CPT11 in a tumor xenograft model while abrogating the intestinal toxicity of CPT11. Overall, we identified for the first time the remission effects of berberine on intestinal mucositis induced by CPT11 without impairing the anti-colorectal cancer efficacy of CPT11 partially via inhibiting bacterial GUS enzyme.

Abstract
Chemotherapy is one of the most commonly used clinical treatments among the currently available cancer therapies. However, the phenomenon of Multidrug resistance (MDR) has become a challenge in the treatment process, weakening the impact of chemotherapy. Extensive research on elucidating the development of cancer MDR has identified the following mechanisms that play a critical role in the development of several MDR reversal agents: abnormal expression of cell membrane transporters, adaptation of cancer cells to the microenvironment, regulation of hypoxia, repair of DNA damage and reduction of apoptosis, the enhancement of the EMT process, the existence of cancer stem cells (CSCs), and the abnormal activation of key signaling pathways. However, they failed to demonstrate significant efficacy due to severe side effects during their clinical trials. Traditional Chinese medicines (TCMs) are known to play an important anti-cancer role since they have low toxicity, high efficacy, and safety and can reverse MDR. TCMs reversal agents can be divided into Chinese medicine monomers, synthetic monomers, analogs, or derivatives. Several studies have shown that TCMs can effectively overcome cancer MDR and can be effectively used for treating cancer patients.

Anti-inflammatory effects of Radix Aucklandiae herbal preparation ameliorate intestinal mucositis induced by 5-fluorouracil in mice. JOURNAL OF ETHNOPHARMACOLOGY 2021; 271:113912. [PMID: 33567307 DOI: 10.1016/j.jep.2021.113912] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Revised: 02/04/2021] [Accepted: 02/05/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE 5-Fluorouracil (5-FU) is a chemotherapy agent that is widely used in clinical oncologic practice. However, intestinal mucositis is the most frequently occurring side effect of cancer therapy with 5-FU. Based on a literature survey, Radix Aucklandiae herbal preparation potentially ameliorates intestinal mucositis in 5-FU-treated mice. AIM OF THE STUDY The aim of this study was to investigate the inflammation and gastrointestinal regulation of intestinal mucositis induced by 5-FU, including the intestinal morphology, as well as the reduction in food intake, body weight loss, and diarrhea. MATERIALS AND METHODS Intestinal mucositis was induced in mice by 5-FU (30 mg/kg, i.p., for 5 consecutive days). The dose-dependent Radix Aucklandiae herbal preparation (0.3, 1, and 3 g/kg/day, p.o.), loperamide (3 mg/kg/day, p.o.) or celecoxib (40 mg/kg/day, p.o.) was concurrently administered until the 7th day. Physical status observation, diarrhea assessment, serum proinflammatory cytokine levels, intestinal villus height and crypt depth, and total goblet cells from tissues were assessed. RESULTS The dosage regimen of 5-FU administration caused severe intestinal mucositis in mice, including damage to the intestinal morphology, accompanied by a reduction in food intake, body weight loss, and diarrhea. The high-dose Radix Aucklandiae herbal preparation significantly relieves 5-FU-induced intestinal mucositis by enhancing proliferative activity in epithelial crypts; improving anepithymia, body weight loss, and diarrhea; and displaying protective effects on goblet cells in intestinal mucosal epithelia. Activation of NF-κB in the intestinal mucositis model was also suppressed by the Radix Aucklandiae herbal preparation, suggesting that it is a potent inhibitor of NF-κB and proinflammatory cytokines, such as IL-1β, IL-6, TNF-α, and COX-2. CONCLUSIONS Our data support the conclusion that the Radix Aucklandiae herbal preparation could effectively ameliorate 5-FU-induced gastrointestinal toxicity and be applied clinically for the prevention of intestinal mucositis during chemotherapy.

Abstract
Background Bu-zhong-yi-qi granule (BZYQ), a sort of Chinese herbal medicine, has exhibited therapeutic effects on ulcerative colitis (UC). However, the mechanism of BZYQ has not been fully clarified. This study was aimed at investigating the effects of BZYQ on UC rats model and at exploring its potential mechanism. Methods The UC rats were established by enema of trinitrobenzene sulfonic acid (TNBS). The therapeutic effects of BZYQ treatment were evaluated by disease activity index (DAI), colon macroscopic damage index (CMDI) scores, and histological observation. The mRNA levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-10 (IL-10) were measured by quantitative real time-polymerase chain reaction (qPCR). The expression of tight junction (TJ) proteins, occludin and claudin-1, in the colon was determined by Western blot and immunofluorescence. The expression of toll-like receptors 4 (TLR4), nuclear factor-kappa B (NF-κB), p-NF-κB, myosin light chain kinase (MLCK), MLC, and p-MLC levels in colon was determined by Western blot or qPCR. Results The results showed that BZYQ could attenuate DAI, CMDI, and histological inflammation. TJ proteins expression was decreased in UC rats, but treatment with BZYQ restored the expression of occludin and claudin-1. In addition, BZYQ administration ameliorated UC-associated increase in the production of TNF-α, IL-1β, and the expression of TLR4, NF-κB, p-NF-κB, MLCK, MLC, and p-MLC, while BZYQ administration increased the production of IL-10. Conclusions The therapeutic effect of BZYQ on UC is at least partially through regulation of the secretion of some inflammatory cytokines and improvement of TJ integrity via TLR4/NF-κB/MLCK pathway.

Effects of mild moxibustion on intestinal microbiome and NLRP3 inflammasome in rats with 5-fluorouracil-induced intestinal mucositis. JOURNAL OF INTEGRATIVE MEDICINE-JIM 2020; 19:144-157. [PMID: 33353843 DOI: 10.1016/j.joim.2020.12.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 06/20/2020] [Indexed: 12/28/2022]
Abstract
OBJECTIVE The present study investigated how mild moxibustion treatment affects the intestinal microbiome and expression of NLRP3-related immune factors in a rat model of intestinal mucositis (IM) induced with 5-fluorouracil (5-Fu). METHODS Forty male Sprague-Dawley rats were randomly divided into control, chemotherapy, moxibustion and probiotics groups. The IM rat model was established by intraperitoneal injection of 5-Fu. Mild moxibustion treatment and intragastric probiotic administration were provided once daily for 15 days. Tissue morphology, serum levels of inflammatory factors and the expression levels of tight junction proteins, caspase-1, gasdermin D and NLRP3 were evaluated in colon tissue, through hematoxylin and eosin staining, electron microscopy, enzyme-linked immunosorbent assay, Western blotting, quantitative real-time reverse transcription polymerase chain reaction and immunofluorescence. Gut microbiome profiling was conducted through 16S rRNA amplicon sequencing. RESULTS Moxibustion and probiotic treatments significantly increased the expression levels of tight junction proteins, reduced cell apoptosis and the expression levels of caspase-1, gasdermin D and NLRP3; they also decreased the serum levels of tumor necrosis factor-α, interleukin (IL)-6, IL-1β and IL-18, while increasing serum levels of IL-10. Moxibustion and probiotic treatments also corrected the reduction in α-diversity and β-diversity in IM rats, greatly increased the proportion of the dominant bacterial genus Lactobacillus and reduced the abundance of the genera Roseburia and Escherichia in chemotherapy-treated rats to levels observed in healthy animals. We also found that these dominant genera were firmly correlated with the regulation of pyroptosis-associated proteins and inflammatory factors. Finally, moxibustion and probiotic treatments elicited similar effects in regulating intestinal host-microbial homeostasis and the expression of NLRP3 inflammasome-related factors. CONCLUSION Moxibustion exerts its therapeutic effect on IM by ameliorating mucosal damage and reducing inflammation. Moreover, moxibustion modulates the gut microbiota, likely via decreasing the expression levels of the NLRP3 inflammasome.

Abstract
A 45-year-old male patient diagnosed as stage IVa pancreatic cancer received anti-cancer treatment with chemotherapy and radiotherapy. During the treatment, he complained of nausea, appetite loss, and fatigue. He received a Kampo diagnosis of qi deficiency, blood stasis, and heat with phlegm; consequently, qi supplementation, smoothing blood, and relieving fever were initiated using Juzentaihoto and Keppuchikuoto. After this treatment, the symptoms showed remarkable improvement. However, computed tomography revealed multiple lung nodules. We prescribed crude drugs with anti-cancer effects, including Scutellaria barbata and Oldenlandia diffusa. These drugs led to slowed development of lung metastases that could be surgically resected. He survived for 7 years after the advanced diagnosis without loss of quality of life. Kampo medicine may be useful for disease control and supportive care in advanced pancreatic cancer patients.

Abstract
Constipation is a common gastrointestinal disorder without effective treatment approach. Buzhongyiqi decoction (BZYQD) is a classical formula that has been commonly used for gastrointestinal disorders for nearly 1,000 years. In this study, we aimed to investigate the protective effect of BZYQD against loperamide-induced constipation and its potential mechanism. Rats with loperamide-induced constipation were orally administered BZYQD. BZYQD treatment obviously increased the small intestinal transit rate and alleviated colon tissue pathological damage. Subsequently, serum metabolomics study was performed to identify the metabolites affected by BZYQD. Metabolomics identified that the levels of 17 serum metabolites, including prostaglandin E2 (PGE2), arachidonic acid (AA), and inositol, were significantly changed in BZYQD-treated group compared with those in the loperamide-induced group. Pathway analysis revealed that those metabolites were mainly associated with arachidonic acid metabolism, biosynthesis of unsaturated fatty acids, ascorbate and aldarate metabolism, inositol phosphate metabolism. Additionally, BZYQD treatment down-regulated the cyclooxygenase-2 expression and decrease production of the proinflammatory mediator PGE2. Further study revealed that BZYQD administration decreased serum levels of the inflammatory factors IL-1β and TNF-α, inhibited phosphorylation of the nuclear transcription factor NF-κB, and down-regulated expression of the inflammatory factors IL-1β and IL-6 in the constipated rat colon. Moreover, BZYQD treatment also increased serum levels of inositol, motilin and gastrin, and promoted gastrointestinal motility. In conclusion, the present study suggested that BZYQD exerted a protective effect against loperamide-induced constipation, which may be associated with its role in regulation of multiple metabolic pathways.

Protective effect of Andrographolide on 5-Fu induced intestinal mucositis by regulating p38 MAPK signaling pathway. Life Sci 2020; 252:117612. [PMID: 32247004 DOI: 10.1016/j.lfs.2020.117612] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2020] [Revised: 03/29/2020] [Accepted: 03/30/2020] [Indexed: 12/28/2022]
Abstract
AIMS Intestinal mucositis is the most common side effect of 5-fluorouracil (5-Fu) treatment in cancer patients. Previous research suggested that andrographolide (Andro) attenuated the intestinal injury in colitis or diarrhea in mice. The present study was aimed at investigating the protective effect of Andro against 5-Fu induced intestinal mucositis and the underlying mechanism. MAIN METHODS BALB/C mice were injected 5-Fu at a dose of 100 mg/kg for 5 days to induce intestinal mucositis. Andro at different doses (25, 50, 100 mg/kg/day) was administered. Weight loss, diarrhea score, cellular apoptosis and proliferation were evaluated. Apoptosis related proteins were detected by Western blotting. Then, NCM460 cells were used to explore the possible mechanism in vitro. The effect of Andro on the anti-tumor efficacy of 5-Fu was investigated in H22 tumor-bearing mice. KEY FINDINGS Andro significantly ameliorated the 5-Fu induced weight loss and diarrhea. The apoptosis of intestinal cells was also attenuated by Andro treatment both in vivo and in vitro. Besides, Andro markedly down-regulated the 5-Fu-induced protein expression of caspase8/3, Bax and the phosphorylation of p38. Moreover, 5-Fu significantly reduced the viability of NCM460 cells, which was restored by the Andro pretreatment. Furthermore, asiatic acid, an agonist of p38 MAPK, reversed the anti-apoptotic effect of Andro in NCM460 cells. Andro did not weaken the anti-H22 tumor effect of 5-Fu in vivo. SIGNIFICANCE We have demonstrated that p38 MAPK inhibition mediates anti-apoptotic effects of Andro against 5-Fu induced intestinal mucositis, suggesting that Andro may benefit the patients undergoing 5-Fu based chemotherapy.

Abstract
Background Diarrhea is a major gastrointestinal complication in cancer patients receiving chemotherapy. Prognosis and treatment of chemotherapy-induced diarrhea (CID) remain unsatisfactory. This study aims to explore the potential of an ancient Chinese Medicine herbal formula Huanglian Jiedu Decoction (HLJDD) as an adjuvant treatment on CID. Method HLJDD extract was prepared by GMP manufacturing standard with quality and stability being checked. 5-fluorouracil (5-Fu) and irinotecan (CPT-11)-induced diarrhea model in mice was established and pre-, co- and post-treatment of HLJDD was implemented. Mechanism of action was explored by detecting related protein expression. In addition, the effect of HLJDD on diarrhea and tumor response induced by clinical regimens FOLFOX and FOLFIRI was measured in murine orthotopic colorectal cancer model. Results HLJDD exhibited consistency in quality and stability after 24-month storage. Pre-treatment of HLJDD, but not co-treatment or post-treatment, could significantly improve the diarrhea score, body weight loss and intestinal damage in 5-Fu- and CPT-11-treated mice. Pre-treatment of HLJDD reduced cell apoptosis in the intestine of chemotherapy-treated mice, and promoted renewal of intestinal cell wall. CD44 was predicted as the potential target of HLJDD-containing compounds in CID. HLJDD pre-treatment induced presentation of CD44-postive cells in the intestine of chemotherapy-treated mice, and initiated expression of stemness-associated genes. Transcriptional products of the downstream Wnt signaling of CD44 were elevated. Furthermore, pre-treatment of HLJDD could significantly improve the tumor response of clinical chemotherapy regimens FOLFOX and FOLFIRI in orthotopic colorectal cancer, and reduce diarrhea and intestinal damage. Conclusion: Our study suggests the potential of HLJDD as a neoadjuvant treatment of chemotherapy by reducing diarrhea and improving tumor response.

Abstract
Myasthenia gravis (MG) is an autoimmune disease. A proportion of MG patients did not get satisfactory results after treatment with pyridostigmine and prednisone. Jia Wei Bu Zhong Yi Qi (Jia Wei BZYQ) decoction, a water extract from multiple herbs, has been demonstrated to be effective in the treatment of multiple "Qi deficiency type" diseases including MG in China. In this text, we investigated protein alterations in the plasma from healthy volunteers (C), MG patients without any treatment (T1), MG patients with routine western medical treatment (T2), and MG patients with combined treatments of Jia Wei BZYQ decoction and routine western medicines (T3) and identified some potential proteins involved in the pathogenesis and treatment of MG. iTRAQ (isobaric tags for relative and absolute quantitation) and 2D-LC-MS/MS (two-dimensional liquid chromatography-tandem mass spectrometry technologies) were employed to screen differentially expressed proteins. The identification, quantification, functional annotation, and interaction of proteins were analyzed by matching software and databases. In our project, 618 proteins were identified, among which 447 proteins had quantitative data. The number of differentially expressed proteins was 110, 117, 143, 115, 86, and 158 in T1 vs. C, T2 vs. C, T2 vs. T1, T3 vs. C, T3 vs. T1, and T3 vs. T2 groups, respectively. Functional annotation results showed that many differentially expressed proteins were closely associated with immune responses. For instance, some key proteins such as C-reactive protein, apolipoprotein C-III, apolipoprotein A-II, alpha-actinin-1, and thrombospondin-1 have been found to be abnormally expressed in T3 group compared to T1 group or T2 group. Interaction network analyses also provided some potential biomarkers or targets for MG management.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) holds that deficiency of spleen-Qi is the major pathogenesis of chemotherapy-induced diarrhea (CID). Herb pair of Atractylodes macrocephala Koidz. (AM) and Panax ginseng C. A. Mey. (PG) has good effects of supplementing Qi and strengthening spleen. AIM OF THE STUDY To investigate therapeutic effects and mechanism of Atractylodes macrocephala essential oil (AMO) and Panax ginseng total saponins (PGS) alone and in combination (AP) on 5-fluorouracil (5-FU) chemotherapy induced diarrhea in mice. MATERIALS AND METHODS The mice were administered with AMO, PGS and AP respectively for 11 days, and intraperitoneally injected with 5-FU for 6 days since the 3rd day of the experiment. During the experiment, the body weights and diarrhea scores of mice were recorded daily. Thymus and spleen indexes were calculated after sacrifice of the mice. Pathological changes in ileum and colonic tissues were examined by hematoxylin-eosin (HE) staining. And the content levels of intestinal inflammatory cytokines were measured by enzyme-linked immmunosorbent assays (ELISA). 16S rDNA Amplicon Sequencing was used to analyze and interpret the gut microbiota of fecal samples. RESULTS AP significantly inhibited body weights loss, diarrhea, reductions of thymus and spleen indexes, and pathological changes of ileums and colons induced by 5-FU. Neither AMO nor PGS alone significantly improved above-mentioned abnormalities. Besides, AP could significantly suppressed the 5-FU-mediated increases of the intestinal inflammatory cytokines (TNF-α, IFN-γ, IL-6, IL-1β and IL-17), while AMO or PGS only inhibited some of them after 5-FU chemotherapy. Gut microbiota analysis indicated that 5-FU induced overall structural changes of gut microbiota were reversed after AP treatment. Additionally, AP significantly modulated the abundances of different phyla similar to normal values, and restored the ratios of Firmicutes/Bacteroidetes (F/B). At genus level, AP treatment dramatically decreased potential pathogens like Bacteroides, Ruminococcus, Anaerotruncus and Desulfovibrio. AP also antagonized the abnormal effects of AMO and PGS alone on certain genera like Blautia, Parabacteroides and Lactobacillus. Neither AMO nor PGS alone inhibited changes of gut microbial structure caused by 5-FU. CONCLUSIONS AP, combination of AMO and PGS, not AMO or PGS alone, significantly ameliorated diarrhea, inhibited intestinal pathology, and modulated gut microbial structure in 5-FU induced mice. AP also antagonized abnormal effects of AMO or PGS on certain genera. The results illustrated that gut microbiota was involved in the combined effects of AP on 5-FU induced diarrhea.

Abstract
Background: Armillariella oral solution (AOS) shows therapeutic effect on gastrointestinal disorders. We aimed to investigate the potential efficacy of AOS on chemotherapy-induced intestinal mucositis in mice. Methods: Intestinal mucositis was induced in C57BL/6 mice by daily intraperitoneal injection of 5-FU (50 mg/kg) for 7 days. Effects of AOS (at 1, 5, and 10 mL/kg), or combined Bifidobacterium and Lactobacillus (CBL, 450 mg/kg) on the accompanying morphometry and histology, expression of Ki-67, caspase-3, Lgr5 and apoptosis of intestinal crypt cells were assessed. Results: Continuous administration of 5-FU to mice caused severe intestinal mucositis, which was histologically characterized by the destruction of intestinal crypts and shortening of villi, accompanied by diarrhea and body weight loss. Daily AOS administration dose-dependently reduced the severity of intestinal mucositis, diarrhea and body weight loss. Similar beneficial effects were observed with CBL. The expression of Ki-67 and Lgr5 decreased and the expression of caspase-3, and the number of apoptotic cells increased 24 h after the first 5-FU administration (P < 0.05), and these responses were significantly reduced by AOS treatment (P < 0.05, at 5 or 10 mL/kg). Conclusions: AOS can alleviate 5-FU-induced mucositis in mice via increasing Lgr5 expression and suppressing apoptotic responses in the intestinal crypt cells.

Abstract
Background Gut microbiota plays a crucial role in the treatment of gastrointestinal (GI) diseases such as chemotherapy-induced diarrhea (CID). Shenzhu Capsule (SZC) is a Chinese herbal formula, which is composed of Renshen (rhizomes of Panax ginseng C. A. Mey.) and Baizhu (rhizomes of Atractylodes macrocephala Koidz.). Many Chinese traditional anti-diarrheal formulae that contain Renshen and Baizhu are capable of effectively alleviating CID. However, the efficacy in vivo and potential mechanism of SZC (the form of compatibility of Renshen and Baizhu) in the treatment of CID had not been elucidated. Here, this study aimed to investigate whether SZC exhibited the anti-diarrheal activity, and whether gut microbiota was involved in the therapeutic effect of SZC on CID. Methods High performance liquid chromatography (HPLC), gas chromatography-mass spectrometer (GC-MS) and infrared spectroscopy (IR) analyses were used to characterize the extracted components in SZC. The mice were orally administrated with SZC in a preventive mode on the first 2 days of this experiment, and then intraperitoneally injected with 5-FU (40 mg/kg/d) for 6 days. SZC treatment lasted until the 3rd day after the end of 5-FU chemotherapy. We investigated the effects of SZC on body weights, diarrhea, thymus/spleen indexes, colonic tissues, and gut microbiota. Colonic histology was examined by hematoxylin-eosin (HE) staining. 16S rDNA Amplicon Sequencing was used to analyze the gut microbial structure from fecal samples. Results SZC significantly increased the body weights and thymus/spleen indexes, alleviated diarrhea, and reversed histopathological changes of colons. In addition, gut microbiota analysis revealed that the overall structure of gut microbiota in CID mice was disturbed, but reversed to the normal state after SZC treatment. At genus level, SZC significantly inhibited the growth of some potential pathogens associated with diarrhea, such as Clostridiumm, Bacteroides, Parabacteroides, Alloprevotella, Acinetobacter and Pseudomonas. Conclusions In our study, these data illustrated that SZC inhibited the growth of many potential pathogens during the alleviation of CID. Gut microbial modulation was associated with the anti-diarrheal activity of SZC.

Abstract
Side effects, including nausea, vomiting, mucositis, peripheral neuropathy, and diarrhea, have been frequently reported in colorectal cancer (CRC) patients undergoing chemotherapy. Chinese Herbal Medicines (CHMs) display distinct clinical outcomes, as a result, they have been increasingly used as an adjuvant therapy to manage chemotherapy-induced side effects. In this review, we aim to intensively explore the molecular mechanisms of CHMs, underline the significance of CHMs in mitigating the side effects induced by chemotherapy, and examine the necessary studies required to understand the role of CHMs in alleviating chemotherapy-induced side effects. Specifically, ginger, Astragali Radix, and Liujunzi Decoction have been verified to ameliorate nausea and vomiting. Banxia Xiexin Decoction and Huangqin Decoction have been confirmed to be beneficial to mucositis and delayed-onset of diarrhea. Moreover, Niuche Shenqi Wan, Guilong Tongluo Decoction, Huangqi Guizhi Wuwu Decoction, and tumeric have been found to display potential therapeutic effects for preventing the genesis and development of peripheral neurotoxicity. These findings have further emphasized the pivotal role of CHMs in improving the outcomes of chemotherapy-induced side effects in CRC. Nonetheless, more molecular evidence is required to comprehensively understand and more appropriately apply CHMs in routine clinical practice for CRC.

Abstract
Cancer is the second leading cause of death in the world. Chemotherapy and radiotherapy are the common cancer treatments. However, the development of adverse effects resulting from chemotherapy and radiotherapy hinders the clinical use, and negatively reduces the quality of life in cancer patients. Natural products including crude extracts, bioactive components-enriched fractions and pure compounds prepared from herbs as well as herbal formulas have been proved to prevent and treat cancer. Of significant interest, some natural products can reduce chemotherapy and radiotherapy-induced oral mucositis, gastrointestinal toxicity, hepatotoxicity, nephrotoxicity, hematopoietic system injury, cardiotoxicity, and neurotoxicity. This review focuses in detail on the effectiveness of these natural products, and describes the possible mechanisms of the actions in reducing chemotherapy and radiotherapy-induced side effects. Recent advances in the efficacy of natural dietary supplements to counteract these side effects are highlighted. In addition, we draw particular attention to gut microbiotan in the context of prebiotic potential of natural products for the protection against cancer therapy-induced toxicities. We conclude that some natural products are potential therapeutic perspective for the prevention and treatment of chemotherapy and radiotherapy-induced side effects. Further studies are required to validate the efficacy of natural products in cancer patients, and elucidate potential underlying mechanisms.

Abstract
5-Fluorouracil (5-FU) is the most frequently prescribed anti-tumor drug, but has been reported to result in intestinal injury. Although some progress has been made in understanding the intestinal toxicity of 5-FU, confusion remains about animal models of 5-FU-induced intestinal injury, especially the dosage of 5-FU. This study aims to assess the dose-response relationship between the severity of intestinal injury and different doses of 5-FU, and to determine a proper dosing for the murine model. We found that mice in the 5-FU groups gradually lost body weight over time. Increasing doses of 5-FU resulted in more severe diarrhea, with a concomitant increase in mortality. Histopathological damage was more severe in mice that received higher doses of 5-FU. In addition, plasma diamine oxidase (DAO) activity decreased in experimental mice with intestinal injury in a dose-dependent way. TUNEL and western blot analysis showed cell apoptosis in the ileum and colon related to 5-FU dosage. However, administration of 200 and 400 mg/kg 5-FU caused extremely high mortality, severe diarrhea and histopathological damage, but 25 mg/kg 5-FU did not result in significant intestinal injury. The severity of intestinal injury induced by 5-FU appeared to be dose-dependent and we concluded that the proper dosage of 5-FU to induce a murine model with intestinal mucositis ranged from 50 mg/kg to 100 mg/kg.

Abstract
AIM Combination therapies of cisplatin with 5-FU (PF) are an effective solution and have been widely used for the treatment of various categories of cancer including anal, gastrointestinal, and oral cancer, as well as head and neck tumors. The effects of combined PF treatment on vital intracellular signalling pathways in nontargeted cells remain unclear. The aim of this study is to explain the possible mechanisms by which combined PF treatment results in retinal toxicity and to investigate the effects of PF on important vital signalling pathways in ARPE 19 retinal pigmented epithelial cells. MATERIALS AND METHODS We analysed the cellular and molecular effects of PF on cell viability, oxidative stress, gene repair response, and induction of apoptosis in ARPE 19 cells using molecular probe fluorescent staining, cell cytometer, RAPD, qRT-PCR, and western blot assays. RESULTS We determined that PF causes excessive generation of reactive oxygen species (ROS) and prevents ROS scavenging by suppressing antioxidant systems. We found induction of DNA damage, particularly mismatch and double strand break repair, in ARPE 19 cells treated with PF. In this study, PF also induced both the intrinsic apoptosis pathway and death receptor signalling in ARPE 19 cells. CONCLUSIONS Our data proved that PF causes cytotoxicity and genotoxicity, at both the cellular and molecular levels, in ARPE 19 cells following particularly prolonged treatment (48 h). Additionally, our results suggest key molecular signals for prevention strategies that can be developed to reduce the severe side effects of PF chemotherapy.

Abstract
Chemotherapy for cancer patients induces damaging tissue reactions along the epithelium of the gastrointestinal tract (GIT). This chemotherapy-induced mucositis (CIM) is a serious side effect of cytotoxic drugs, and several animal models of CIM have been developed, mainly in rodents and piglets, to help understand the progression of CIM and how to prevent it. Animal models allow highly controlled experimental conditions, detailed organ (e.g., GIT) insights, standardized, clinically relevant treatment regimens, and discovery of new biomarkers. Still, surprisingly few results from animal models have been translated into clinical CIM management and treatments. The results obtained from specific animal models can be difficult to translate to the diverse range of CIM manifestations in patients, which vary according to the antineoplastic drugs, dose, underlying (cancer) disease, and patient characteristics (e.g., age, genetics, and body constitution). Another factor that hinders the direct use of results from animals is inadequate collaboration between basic science and clinical science in relation to CIM. Here, we briefly describe CIM pathophysiology, particularly the basic knowledge that has been obtained from CIM animal models. These model studies have indicated potential new preventive and ameliorating interventions, including supplementation with natural bioactive diets (e.g., milk fractions, colostrum, and plant extracts), nutrients (e.g., polyunsaturated fatty acids, short-chain fatty acids, and glutamine), and growth factor peptides (e.g., transforming growth factor and glucagon-like peptide-2), as well as manipulations of the gut microbiota (e.g., prebiotics, probiotics, and antibiotics). Rodent CIM models allow well-controlled, in-depth studies of animals with or without tumors while pig models more easily make clinically relevant treatment regimens possible. In synergy, animal models of CIM provide the basic physiological understanding and the new ideas for treatment that are required to make competent decisions in clinical practice.

Herbal Formula Modified Buzhong-Yiqi-Tang for Functional Constipation in Adults: A Meta-Analysis of Randomized Controlled Trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:9602525. [PMID: 29552087 PMCID: PMC5820555 DOI: 10.1155/2018/9602525] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/24/2017] [Revised: 11/09/2017] [Accepted: 12/11/2017] [Indexed: 02/05/2023]
Abstract
Background Herbal formula Modified Buzhong-Yiqi-Tang (MBYT) has been widely used for the treatment of functional constipation in East Asia, but its efficacy and safety are unclear. Methods The study was to evaluate the efficacy and safety of MBYT for adult patients with functional constipation. Randomized clinical trials were selected according to predefined inclusion and exclusion criteria. Results In total, twenty-five randomized controlled clinical trials were included with 2089 patients. There was evidence that MBYT treatment significantly improved the symptoms of functional constipation compared with stimulant laxatives, osmotic laxatives, and prokinetic agents. Our results also demonstrated that, when used as an adjuvant therapy, MBYT significantly improved the symptoms of functional constipation, when compared with osmotic laxatives alone, prokinetic agents alone, and biofeedback alone. Moreover, patients taking MBYT experienced fewer adverse events compared to the control groups. Conclusion This review suggests that MBYT appears to have excellent therapeutic effect on adult patients with functional constipation and no serious side effects were identified. However, due to overall limited quality, the therapeutic benefit of MBYT may be substantiated to a limited degree. Better methodological quality and large controlled trials are expected to further quantify the therapeutic effect of MBYT.

Early traditional Chinese medicine bundle therapy for the prevention of sepsis acute gastrointestinal injury in elderly patients with severe sepsis. Sci Rep 2017; 7:46015. [PMID: 28382954 PMCID: PMC5382529 DOI: 10.1038/srep46015] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Accepted: 03/08/2017] [Indexed: 12/13/2022] Open
Abstract
This study aimed to study the effect of early traditional Chinese medicine bundle therapy on the prevention of sepsis-associated acute gastrointestinal injury (AGI). This was a multicenter, prospective, observational, non-randomized cohort study of 296 consecutive patients with severe sepsis during 2013/3 and 2014/11; 150 patients received standard treatments (controls) and 146 received traditional Chinese medicine bundle therapy (intervention group) (herbal decoction gavage based on syndrome differentiation, Chinese acupuncture, application of mirabilite, and defecation mixture). D-lactic acid, diamine oxidase, endotoxin, gastrin, motilin, and intra-abdominal pressure were measured. AGI was categorized into four levels. Compared with controls, D-lactic acid, diamine oxidase, endotoxin, gastrin, and intra-abdominal pressure in the intervention group were decreased, and motilin was increased on day 7. AGI incidence in the intervention group was lower than in controls. GIF scores of the intervention AGI II and III groups were lower than in controls. The APACHE II scores of the intervention AGI II, III, and IV groups were lower than in controls. Compared with controls, mechanical ventilation time and ICU stay in the intervention group were shorter, and 28-day overall and AGI-attributed mortality were lower. For elderly patients with severe sepsis, early traditional Chinese medicine bundle therapy could decrease AGI incidence and improve prognosis.

Bu-Zhong-Yi-Qi Decoction, the Water Extract of Chinese Traditional Herbal Medicine, Enhances Cisplatin Cytotoxicity in A549/DDP Cells through Induction of Apoptosis and Autophagy. BIOMED RESEARCH INTERNATIONAL 2017; 2017:3692797.

Abstract
Cisplatin is one of the most active cytotoxic agents for non-small cell lung cancer (NSCLC) treatment. However, the development of cisplatin resistance is common. Bu-Zhong-Yi-Qi decoction (BZYQD), a Chinese traditional herbal medicine, is widely used for the enhancement of antitumor effect in other medications. In this study, we evaluated the effect and drug-resistance reversal mechanism of BZYQD combined with cisplatin on cisplatin-resistant A549/DDP cells. Our results showed that BZYQD exhibited direct cytotoxic and chemosensitizing effects. Cotreatment with BZYQD and cisplatin induced intrinsic apoptotic pathways which were measured by condensed nuclear chromatin, Annexin V/PI apoptosis assay, and apoptosis related proteins expression. In addition, cotreatment with BZYQD and cisplatin also activated autophagy, as indicated by an increase in LC3 puncta, classical autophagosomes and/or autolysosomes, and an accumulation of LC3-II and ATG7 protein. Finally, cotreatment with BZYQD and cisplatin resulted in the generation of ROS and scavenging ROS by NAC almost completely suppressing cell death. These results suggest that cotreatment with BZYQD and cisplatin might reverse cisplatin resistance by inducing ROS accumulation, which activates apoptosis and autophagy by oxidative stress. The combination of BZYQD and cisplatin may represent a novel approach in treatment for NSCLC and thus offer a new target for chemotherapy.
