| 1 | 中枢性性早熟诊断与治疗共识(2015)显示文摘中枢性性早熟(central precocious puberty,CPP)是指由于下丘脑-垂体-性腺轴(hypothalamic-pituitary-gonadal axis,HPGA)功能提前启动而导致女孩8岁前,男孩9岁前出现内外生殖器官快速发育及第二性征呈现的一种常见儿科内分泌疾病.发病率约为1/5 000 ~ 1/10 000,女孩约为男孩的5~10倍. | 罗小平 | 2015 | 中华儿科杂志2015，53，6： | 377 |
| 2 | Gut-liver axis and probiotics: Their role in non-alcoholic fatty liver disease显示文摘The incidence of obesity and its related conditions, including non-alcoholic fatty liver disease(NAFLD), has dramatically increased in all age groups worldwide. Given the health consequences of these conditions, and the subsequent economic burden on healthcare systems, their prevention and treatment have become major priorities. Because standard dietary and lifestyle changes and pathogenically-oriented therapies(e.g., antioxidants, oral hypoglycemic agents, and lipid-lowering agents) often fail due to poor compliance and/or lack of efficacy, novel approaches directed toward other pathomechanisms are needed. Here we present several lines of evidence indicating that, by increasing energy extraction in some dysbiosis conditions or small intestinal bacterial overgrowth,specific gut microbiota and/or a'low bacterial richness'may play a role in obesity,metabolic syndrome,and fatty liver.Under conditions involving a damaged intestinal barrier('leaky gut'),the gut-liver axis may enhance the natural interactions between intestinal bacteria/bacterial products and hepatic receptors(e.g.,toll-like receptors),thus promoting the following cascade of events:oxidative stress,insulinresistance,hepatic inflammation,and fibrosis.We also discuss the possible modulation of gut microbiota by probiotics,as attempted in NAFLD animal model studies and in several pilot pediatric and adult human studies.Globally,this approach appears to be a promising and innovative add-on therapeutic tool for NAFLD in the context of multi-target therapy. | Giulia Paolella Claudia Mandato Luca Pierri Marco Poeta Martina Di Stasi Pietro Vajro | 2014 | World Journal of Gastroenterology2014，20，42： | 55 |
| 3 | Brain-gut-microbiota axis in Parkinson's disease显示文摘Parkinson's disease(PD) is characterized by alphasynucleinopathy that affects all levels of the braingut axis including the central, autonomic, and enteric nervous systems. Recently, it has been recognized that the brain-gut axis interactions are significantly modulated by the gut microbiota via immunological,neuroendocrine, and direct neural mechanisms. Dysregulation of the brain-gut-microbiota axis in PD may be associated with gastrointestinal manifestations frequently preceding motor symptoms, as well as with the pathogenesis of PD itself, supporting the hypothesis that the pathological process is spread from the gut to the brain. Excessive stimulation of the innate immune system resulting from gut dysbiosis and/or small intestinal bacterial overgrowth and increased intestinal permeability may induce systemic inflammation, while activation of enteric neurons and enteric glial cells may contribute to the initiation of alpha-synuclein misfolding.Additionally, the adaptive immune system may be disturbed by bacterial proteins cross-reacting with human antigens. A better understanding of the brain-gutmicrobiota axis interactions should bring a new insight in the pathophysiology of PD and permit an earlier diagnosis with a focus on peripheral biomarkers within the enteric nervous system. Novel therapeutic options aimed at modifying the gut microbiota composition and enhancing the intestinal epithelial barrier integrity in PD patients could influence the initial step of the following cascade of neurodegeneration in PD. | Agata Mulak Bruno Bonaz | 2015 | World Journal of Gastroenterology2015，21，37： | 60 |
| 4 | Acupuncture and regulation of gastrointestinal function显示文摘In China, acupuncture has been considered an effective method for treating gastrointestinal(GI) dysfunction diseases for thousands of years. In fact, acupuncture has gained progressive acceptance from both practitioners and patients worldwide. However, the therapeutic effects and underlying mechanisms in treating GI dysfunction have not yet been established due to a lack of systematic and comprehensive review articles. Therefore, the aim of this review is to discuss the efficacy of acupuncture as a treatment for GI dysfunction and the associated underlying mechanisms. A search of Pub Med was conducted for articles that were published over the past 10 years using the terms 'acupuncture', 'gastrointestine', and other relevant keywords. In the following review, we describe the effect and underlying mechanisms of acupuncture on GI function from the perspectives of GI motility, visceral sensitivity, the GI barrier, and the brain-gut axis. The dual regulatory effects of acupuncture may manifest by promoting gastric peristalsis in subjects with low initial gastric motility, and suppressing peristalsis in subjects with active initial motility. In addition, the regulation of acupuncture on gastric motility may be intensitydependent. Our findings suggest that further studies are needed to investigate the effects and more systematic mechanisms in treating GI dysfunction, and to promote the application of acupuncture for the treatment of GI diseases. | Hui Li Tian He Qian Xu Zhe Li Yan Liu Fang Li Bo-Feng Yang Cun-Zhi Liu | 2015 | World Journal of Gastroenterology2015，21，27： | 41 |
| 5 | Gut-liver axis in liver cirrhosis: How to manage leaky gut and endotoxemia显示文摘A 'leaky gut' may be the cutting edge for the passage of toxins, antigens or bacteria into the body, and may play a pathogenic role in advanced liver cirrhosis and its complications. Plasma endotoxin levels have been admitted as a surrogate marker of bacterial translocation and close relations of endotoxemia to hyperdynamic circulation, portal hypertension, renal, cardiac, pulmonary and coagulation disturbances have been reported. Bacterial overgrowth, increased intestinal permeability, failure to inactivate endotoxin,activated innate immunity are all likely to play a role in the pathological states of bacterial translocation. Therapeutic approach by management of the gut-liver axis by antibiotics, probiotics, synbiotics, prebiotics and their combinations may improve the clinical course of cirrhotic patients. Special concern should be paid on anti-endotoxin treatment. Adequate management of the gut-liver axis may be effective for prevention of liver cirrhosis itself by inhibiting the progression of fibrosis. | Hiroshi Fukui | 2015 | World Journal of Hepatology2015，7，3： | 32 |
| 6 | Brain-gut axis in the pathogenesis of Helicobacter pylori infection显示文摘Helicobacter pylori(H.pylori)infection is the main pathogenic factor for upper digestive tract organic diseases.In addition to direct cytotoxic and proinflammatory effects,H.pylori infection may also induce abnormalities indirectly by affecting the brain-gut axis,similar to other microorganisms present in the alimentary tract.The brain-gut axis integrates the central,peripheral,enteric and autonomic nervous systems,as well as the endocrine and immunological systems,with gastrointestinal functions and environmental stimuli,including gastric and intestinal microbiota.The bidirectional relationship between H.pylori infection and the brain-gut axis influences both the contagion process and the host’s neuroendocrine-immunological reaction to it,resulting in alterations in cognitive functions,food intake and appetite,immunological response,and modification of symptom sensitivity thresholds.Furthermore,disturbances in the upper and lower digestive tract permeability,motility and secretion can occur,mainly as a form of irritable bowel syndrome.Many of these abnormalities disappear following H.pylori eradication.H.pylori may have direct neurotoxic effects that lead to alteration of the brain-gut axis through the activation of neurogenic inflammatory processes,or by microelement deficiency secondary to functional and morphological changes in the digestive tract.In digestive tissue,H.pylori can alter signaling in the brain-gut axis by mast cells,the main brain-gut axis effector,as H.pylori infection is associated with decreased mast cell infiltration in the digestive tract.Nevertheless,unequivocal data concerning the direct and immediate effect of H.pylori infection on the brain-gut axis are still lacking.Therefore,further studies evaluating the clinical importance of these host-bacteria interactions will improve our understanding of H.pylori infection pathophysiology and suggest new therapeutic approaches. | Jacek Budzyński Maria Kopocka | 2014 | World Journal of Gastroenterology2014，20，18： | 29 |
| 7 | Effects of early enteral nutrition on Th17/Treg cells and IL-23/IL-17 in septic patients显示文摘BACKGROUND The imbalance of Th17/Treg cells and the IL-23/IL-17 axis have been confirmed to be associated with sepsis and various inflammatory diseases. Early enteral nutrition (EEN) can modulate the inflammatory response, improve immune dysfunction, and prevent enterogenic infection in critically ill patients;however, the precise mechanisms remain unclear. Considering the important roles of Th17 and Treg lymphocytes in the development of inflammatory and infectious diseases, we hypothesized that EEN could improve the immune dysfunction in sepsis by maintaining a balanced Th17/Treg cell ratio and by regulating the IL- 23/IL-17 axis. AIM To investigate the effects of EEN on the Th17/Treg cell ratios and the IL-23/IL-17 axis in septic patients. METHODS In this prospective clinical trial, patients were randomly divided into an EEN or delayed enteral nutrition (DEN) group. Enteral feeding was started within 48 h in the EEN group, whereas enteral feeding was started on the 4th day in the DEN group. The Th17 and Treg cell percentages and the interleukin levels were tested on days 1, 3, and 7 after admission. The clinical severity and outcome variables were also recorded. RESULTS Fifty-three patients were enrolled in this trial from October 2017 to June 2018. The Th17 cell percentages, Th17/Treg cell ratios, IL-17, IL-23, and IL-6 levels of the EEN group were lower than those of the DEN group on the 7th day after admission (P < 0.05). The duration of mechanical ventilation and of the intensive care unit stay of the EEN group were shorter than those of the DEN group (P <0.05). However, no difference in the 28-d mortality was found between the two groups (P = 0.728). CONCLUSION EEN could regulate the imbalance of Th17/Treg cell ratios and suppress the IL- 23/IL-17 axis during sepsis. Moreover, EEN could reduce the clinical severity of sepsis but did not reduce the 28-d mortality of septic patients. | Jia-Kui Sun Wen-Hao Zhang Wen-Xiu Chen Xiang Wang Xin-Wei Mu | 2019 | World Journal of Gastroenterology2019，25，22： | 27 |
| 8 | Regulatory effect of a Chinese herbal medicine formula on nonalcoholic fatty liver disease显示文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)has become a major cause of chronic liver disease.The Chinese herbal medicine(CHM)Dachaihu decoction(DCHD)has been proved to treat NAFLD with good efficacy in previous studies.Based on the TCM principle of formula formation,we divided DCHD into soothing liver part,invigorating spleen part,and dredging intestine part.Marshall officially proposed the concept of“intestinal-hepatic axis”,which systematically explains the interactions between the intestine and liver.We hypothesized that the effect of CHM on NAFLD is achieved by regulating the liver and intestine.Thus,we aimed to investigate the possible effect of a CHM formula on NAFLD in a rat model.AIM To investigate the effects of a CHM formula(a decoction of Chinese thorowax root,scutellaria root,and white peony root)on NAFLD and its regulatory effect on the“intestinal-liver”axis.METHODS Sixty rats were randomly divided into control,model,pioglitazone hydrochloride(PH),and CHM(a decoction of Chinese thorowax root,scutellaria root,and white peony root)groups.An NAFLD rat model was established using a high-fat highfructose diet for 16 wk.From the 13th week,rats were administered with PH or a decoction of Chinese thorowax,scutellaria,and white peony root(CHM group)for 4 wk.Rats in the control group and model group were administered with an equal volume of distilled water.At the end of the study,blood was collected via the abdominal aorta.Liver tissues were harvested and any morphological changes were observed by hematoxylin-eosin(HE)staining,Oil red O staining,and Masson staining.In addition,blood lipids,liver function markers,and triglyceride(TG)in liver tissues were analyzed.The levels of transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),Toll-like receptor-4(TLR4),and nuclear factor-kappa B(NF-кB)in liver tissues and secreted immunoglobulin A(sIgA)in intestinal tissues were analyzed by ELISA,and protein and mRNA expression of occludin and zonula occludens-1(ZO-1)in the intestine were measured using Western blot and reverse transcriptionquantitative polymerase chain reaction,respectively.The endotoxin level in plasma was detected by endpoint chromogenic assay.RESULTS Compared to the normal control group,the liver coefficient,serum TG,total cholesterol(TC),low density lipoprotein(LDL),aspartate aminotransferase(AST),and alanine aminotransferase(ALT),blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues increased significantly in the model group,while serum high density lipoprotein(HDL),intestinal sIgA,and protein and mRNA expression of occludin and ZO-1 decreased significantly in the model group(P<0.01).PH and CHM attenuated the elevated liver coefficient,serum TG,TC,LDL,AST,and ALT,blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues and increased serum HDL levels compared to the model group(P<0.01).Intestinal sIgA and the protein and mRNA expression of intestinal occludin and ZO-1 were significantly increased in the PH group compared to the model and CHM groups(P<0.01).CONCLUSION The decoction of Chinese thorowax root,scutellaria root,and white peony root is beneficial in regulating lipid metabolism and liver function,which indicates that it has a good effect on the liver.To a certain extent,this CHM formula can affect both the liver and intestine,while its effect on the liver is superior to that on the intestine. | Jia-Min Yang Yan Sun Min Wang Xin-Lei Zhang Shu-Jing Zhang Yu-Shan Gao Lin Chen Meng-Yao Wu Lu Zhou Yu-Mei Zhou Yue Wang Feng-Jie Zheng Yu-Hang Li | 2019 | World Journal of Gastroenterology2019，25，34： | 24 |
| 9 | Global optimization of tool path for five-axis flank milling with a cylindrical cutter显示文摘In this paper, optimum positioning of cylindrical cutter for five-axis flank milling of non-developable ruled surface is addressed from the perspective of surface approximation. Based on the developed interchangeability principle, global optimization of the five-axis tool path is modeled as approximation of the tool envelope surface to the data points on the design surface following the minimum zone criterion recommended by ANSI and ISO standards for tolerance evaluation. By using the signed point-to-surface distance function, tool path plannings for semi-finish and finish millings are formulated as two constrained optimization problems in a unified framework. Based on the second order Taylor approximation of the distance function, a sequential approximation algorithm along with a hierarchical algorithmic structure is developed for the optimization. Numerical examples are presented to confirm the validity of the proposed approach. | DING Han1 & ZHU LiMin2 1 State Key Laboratory of Digital Manufacturing Equipment and Technology, Huazhong University of Science and Technology, Wuhan 430074, China 2 School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China | 2009 | Science China(Technological Sciences)2009，52，8： | 23 |

| 11 | Brucea javanica oil emulsion improves the effect of radiotherapy on esophageal cancer cells by inhibiting cyclin D1-CDK4/6 axis显示文摘BACKGROUND Esophageal cancer is one of the most common cancers around the world, and it has high incidence and mortality rates. The conventional therapy for esophageal cancer is radiotherapy, although its effect is highly limited by the resistance of esophageal cancer cells. Thus, strong radiosensitizers can be very crucial during radiotherapy against esophageal cancer. Brucea javanica oil emulsion (BJOE) is a widely used drug against various cancers, such as liver, colon, and ovarian cancer. However, its anti-cancer effect and mechanism and the use of BJOE as a radiosensitizer have not been explored in esophageal cancer. AIM To evaluate the anti-cancer effect and mechanism of BJOE and explore the potential use of BJOE as a radiosensitizer during radiotherapy. METHODS The inhibitory effect of BJOE and its enhancement function with radiation on cell viability were examined with the calculated half-maximal effective concentration and half-maximal lethal concentration. The influence of BJOE on cell migration and invasion were measured with EC109 and JAR cells by wound-healing and transwell assay. Clonogenesis and apoptotic rate, which was measured by Hoechst staining, were investigated to confirm its enhancement function with radiation. To investigate the molecular pathway underlying the effect of BJOE, the expressions of several apoptosis- and cycle-related proteins was detected by western blotting.cell lines more than normal cell lines, and it markedly reduced migration and invasion in esophageal cancer cells (EC109 and JAR). Moreover, it promoted cell apoptosis and enhanced the effect of radiotherapy against esophageal cancerous cells. In the viability test, the values of half-maximal effective concentration and half-maximal lethal concentration were reduced. Compared to the control, only around 1/5 colonies formed when using BJOE and radiation together in the clonogenic assay. The apoptotic rate in EC109 was obviously promoted when BJOE was added during radiotherapy. Our study suggests that the expression of the apoptosis-proteins Bax and p21 were increased, while the expression of Bcl-2 was stable. Further detection of downstream proteins revealed that the expression of cyclin D1 and cyclin-dependent kinase 4/6 were significantly decreased. CONCLUSION BJOE has a strong anti-cancer effect on esophageal cancer and can be used as a radiosensitizer to promote apoptosis in cancerous esophageal cells via the cyclin D1-cyclin-dependent kinase 4/6 axis. | Zhong-Hua Qiu Wei-Wei Zhang Hong-Hua Zhang Gui-Hua Jiao | 2019 | World Journal of Gastroenterology2019，25，20： | 21 |

| 13 | Gut microbial dysbiosis associates hepatocellular carcinoma via the gut-liver axis显示文摘Background: Hepatocellular carcinoma(HCC) is one of the most common malignancies in the world. Gut microbiota has been demonstrated to play a critical role in liver inflammation, chronic fibrosis, liver cirrhosis, and HCC development through the gut-liver axis. Data sources: Recently there have been several innovative studies investigating gut microbial dysbiosismediated enhancement of HCC through the gut-liver axis. Literatures from January 1998 to January 2018 were searched in the Pub Med database using the keywords 'gut microbiota' and 'hepatocellular carcinoma' or 'liver cancer', and the results of experimental and clinical studies were analyzed. Results: Gut microbial dysbiosis accompanies the progression of alcoholic liver disease, non-alcoholic fatty liver disease and liver cirrhosis, and promotes HCC progression in an experimental mouse model. The immune system and key factors such as Toll-like receptor 4 are involved in the process. There is evidence for gut microbial dysbiosis in hepatitis virus-related HCC patients. Conclusions: Gut microbial dysbiosis is closely associated with hepatic inflammation disease and HCC through the gut-liver axis. With the enhanced understanding of the interactions between gut microbiota and liver through the gut-liver axis, new treatment strategies for HCC are being developed. | Jian-Wen Jiang Xin-Hua Chen Zhigang Ren Shu-Sen Zheng | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，1： | 19 |
| 14 | Intestinal permeability in the pathogenesis of liver damage: From non-alcoholic fatty liver disease to liver transplantation显示文摘The intimate connection and the strict mutual cooperation between the gut and the liver realizes a functional entity called gut-liver axis.The integrity of intestinal barrier is crucial for the maintenance of liver homeostasis.In this mutual relationship,the liver acts as a second firewall towards potentially harmful substances translocated from the gut,and is,in turn,is implicated in the regulation of the barrier.Increasing evidence has highlighted the relevance of increased intestinal permeability and consequent bacterial translocation in the development of liver damage.In particular,in patients with non-alcoholic fatty liver disease recent hypotheses are considering intestinal permeability impairment,diet and gut dysbiosis as the primary pathogenic trigger.In advanced liver disease,intestinal permeability is enhanced by portal hypertension.The clinical consequence is an increased bacterial translocation that further worsens liver damage.Furthermore,this pathogenic mechanism is implicated in most of liver cirrhosis complications,such as spontaneous bacterial peritonitis,hepatorenal syndrome,portal vein thrombosis,hepatic encephalopathy,and hepatocellular carcinoma.After liver transplantation,the decrease in portal pressure should determine beneficial effects on the gut-liver axis,although are incompletely understood data on the modifications of the intestinal permeability and gut microbiota composition are still lacking.How the modulation of the intestinal permeability could prevent the initiation and progression of liver disease is still an uncovered area,which deserves further attention. | Alberto Nicoletti Francesca Romana Ponziani Marco Biolato Venanzio Valenza Giuseppe Marrone Gabriele Sganga Antonio Gasbarrini Luca Miele Antonio Grieco | 2019 | World Journal of Gastroenterology2019，25，33： | 19 |
| 15 | Virus-induced accumulation of intracellular bile acids activates the TGR5-β-arrestin-SRC axis to enable innate antiviral immunity显示文摘The mechanisms on metabolic regulation of immune responses are still elusive. We show here that viral infection induces immediate-early NF-kB activation independent of viral nucleic acid-triggered signaling, which triggers a rapid transcriptional induction of bile acid (BA) transporter and rate-limiting biosynthesis enzymes as well as accumulation of intracellular BAs in divergent cell types. The accumulated intracellular BAs activate SRC kinase via the TGR5-GRK-卩-arrestin axis, which mediates tyrosine phosphorylation of multiple antiviral signaling components including RIG-I, VISA/MAVS, MITA/STING, TBK1 and IRF3. The tyrosine phosphorylation of these components by SRC conditions for efficient innate antiviral immune response. Consistently, TGR5 deficiency impairs innate antiviral immunity, whereas BAs exhibit potent antiviral activity in wild-type but not TGR5-deficient cells and mice. Our fin dings reveal an intrinsic and un iversal role of intracellular BA metabolism in innate antiviral immunity. | Ming-Ming Hu Wen-Rui He Peng Gao Qing Yang Ke He Li-Bo Cao Shu Li Yu-Qi Feng Hong-Bing Shu | 2019 | Cell Research2019，29，3： | 18 |
| 16 | Intestinal Microbiota in Early Life and Its Implications on Childhood Health显示文摘Trillions of microbes reside in the human body and participate in multiple physiological and pathophysiological processes that affect host health throughout the life cycle. The microbiome is hallmarked by distinctive compositional and functional features across different life periods.Accumulating evidence has shown that microbes residing in the human body may play fundamental roles in infant development and the maturation of the immune system. Gut microbes are thought to be essential for the facilitation of infantile and childhood development and immunity by assisting in breaking down food substances to liberate nutrients, protecting against pathogens, stimulating or modulating the immune system, and exerting control over the hypothalamic–pituitary–adrenal axis.This review aims to summarize the current understanding of the colonization and development of the gut microbiota in early life, highlighting the recent findings regarding the role of intestinal microbes in pediatric diseases. Furthermore, we also discuss the microbiota-mediated therapeutics that can reconfigure bacterial communities to treat dysbiosis. | Lu Zhuang Haihua Chen Sheng Zhang Jiahui Zhuang Qiuping Li Zhichun Feng | 2019 | Genomics, Proteomics & Bioinformatics2019，17，1： | 16 |
| 17 | Clinical impact of microbiome in patients with decompensated cirrhosis显示文摘Cirrhosis is an increasing cause of morbidity and mortality. Recent studies are trying to clarify the role of microbiome in clinical exacerbation of patients with decompensated cirrhosis. Nowadays, it is accepted that patients with cirrhosis have altered salivary and enteric microbiome, characterized by the presence of dysbiosis. This altered microbiome along with small bowel bacterial overgrowth, through translocation across the gut, is associated with the development of decompensating complications. Studies have analyzed the correlation of certain bacterial families with the development of hepatic encephalopathy in cirrhotics. In general, stool and saliva dysbiosis with reduction of autochthonous bacteria in patients with cirrhosis incites changes in bacterial defenses and higher risk for bacterial infections, such as spontaneous bacterial peritonitis, and sepsis. Gut microbiome has even been associated with oncogenic pathways and under circumstances might promote the development of hepatocarcinogenesis. Lately, the existence of the oral-gutliver axis has been related with the development of decompensating events. This link between the liver and the oral cavity could be via the gut through impaired intestinal permeability that allows direct translocation of bacteria from the oral cavity to the systemic circulation. Overall, the contribution of the microbiome to pathogenesis becomes more pronounced with progressive disease and therefore may represent an important therapeutic target in the management of cirrhosis. | Theodora Oikonomou George V Papatheodoridis Michael Samarkos Ioannis Goulis Evangelos Cholongitas | 2018 | World Journal of Gastroenterology2018，24，34： | 16 |
| 18 | Functional gastrointestinal disorders and gut-brain axis: What does the future hold?显示文摘Despite their high prevalence, lack of understanding of the exact pathophysiology of the functional gastrointestinal disorders has restricted us to symptomatic diagnostic tools and therapies. Complex mechanisms underlying the disturbances in the bidirectional communication between the gastrointestinal tract and the brain have a vital role in the pathogenesis and are key to our understanding of the disease phenomenon. Although we have come a long way in our understanding of these complex disorders with the help of studies on animals especially rodents, there need to be more studies in humans, especially to identify the therapeutic targets. This review study looks at the anatomical features of the gut-brain axis in order to discuss the different factors and underlying molecular mechanisms that may have a role in the pathogenesis of functional gastrointestinal disorders. These molecules and their receptors can be targeted in future for further studies and possible therapeutic interventions. The article also discusses the potential role of artificial intelligence and machine learning and its possible role in our understanding of these scientifically challenging disorders. | Kashif Mukhtar Hasham Nawaz Shahab Abid | 2019 | World Journal of Gastroenterology2019，25，5： | 15 |
| 19 | New therapeutic perspectives in irritable bowel syndrome: Targeting low-grade inflammation, immuno-neuroendocrine axis, motility, secretion and beyond显示文摘Irritable bowel syndrome(IBS)is a chronic,recurring,and remitting functional disorder of the gastrointestinal tract characterized by abdominal pain,distention,and changes in bowel habits.Although there are several drugs for IBS,effective and approved treatments for one or more of the symptoms for various IBS subtypes are needed.Improved understanding of pathophysiological mechanisms such as the role of impaired bile acid metabolism,neurohormonal regulation,immune dysfunction,the epithelial barrier and the secretory properties of the gut has led to advancements in the treatment of IBS.With regards to therapies for restoring intestinal permeability,multiple studies with prebiotics and probiotics are ongoing,even if to date their efficacy has been limited.In parallel,much progress has been made in targeting low-grade inflammation,especially through the introduction of drugs such as mesalazine and rifaximin,even if a better knowledge of the mechanisms underlying the low-grade inflammation in IBS may allow the design of clinical trials that test the efficacy and safety of such drugs.This literature review aims to summarize the findings related to new and investigational therapeutic agents for IBS,most recently developed in preclinical as well as Phase 1 and Phase 2clinical studies. | Emanuele Sinagra Gaetano Cristian Morreale Ghazaleh Mohammadian Giorgio Fusco Valentina Guarnotta Giovanni Tomasello Francesco Cappello Francesca Rossi Georgios Amvrosiadis Dario Raimondo | 2017 | World Journal of Gastroenterology2017，23，36： | 14 |
| 20 | Sex hormones in the modulation of irritable bowel syndrome显示文摘Compelling evidence indicates sex and gender differences in epidemiology,symptomatology,pathophysiology,and treatment outcome in irritable bowel syndrome(IBS).Based on the female predominance as well as the correlation between IBS symptoms and hormonal status,several models have been proposed to examine the role of sex hormones in gastrointestinal(GI)function including differences in GI symptoms expression in distinct phases of the menstrual cycle,in pre-and post-menopausal women,during pregnancy,hormonal treatment or after oophorectomy.Sex hormones may influence peripheral and central regulatory mechanisms of the brain-gut axis involved in the pathophysiology of IBS contributing to the alterations in visceral sensitivity,motility,intestinal barrier function,and immune activation of intestinal mucosa.Sex differences in stress response of the hypothalamic-pituitary-adrenal axis and autonomic nervous system,neuroimmune interac-tions triggered by stress,as well as estrogen interactions with serotonin and corticotropin-releasing factor signaling systems are being increasingly recognized.A concept of'microgenderome'related to the potential role of sex hormone modulation of the gut microbiota is also emerging.Significant differences between IBS female and male patients regarding symptomatology and comorbidity with other chronic pain syndromes and psychiatric disorders,together with differences in efficacy of serotonergic medications in IBS patients confirm the necessity for more sex-tailored therapeutic approach in this disorder. | Agata Mulak Yvette Taché Muriel Larauche | 2014 | World Journal of Gastroenterology2014，20，10： | 14 |
