| 3 | Probiotics in hepatology显示文摘The paper provides a basic review of intestinal micro- flora and its importance in liver diseases. The intestinal microflora has many important functions, above all to maintain the microbial barrier against established as well as potential pathogens. Furthermore, it influences the motility and perfusion of the intestinal wall, stimu- lates the intestinal immune system and therefore also the so-called common mucosal immune system, re- ducing bacterial translocation and producing vitamins. Immune homeostasis at mucosal level results from a controlled response to intestinal luminal antigens. In liver cirrhosis, there are many changes in its function, mostly an increase in bacterial overgrowth and trans- location. In this review, probiotics and their indications in hepatology are generally discussed. According to recent knowledge, these preparations are indicated in clinical practice only for cases of hepatic encephalopa- thy. Probiotics are able to decrease the permeability ofthe intestinal wall, and decrease bacterial translocation and endotoxemia in animal models as well as in clinical studies, which is extremely important in the prevention of complications of liver cirrhosis and infection after liv- er transplantation. Probiotics could limit oxidative and inflammatory liver damage and, in some situations, improve the histological state, and thus non-alcoholic steatohepatitis could be considered as another possible indication. ? 2011 Baishideng.

| 5 | Impact of a clinical pathway on treatment outcome in patients with acute pancreatitis显示文摘AIM:To determine the impact of a clinical pathway(CP) on acute pancreatitis(AP) treatment outcome.METHODS:A retrospective analysis of medical records was performed. We compared the results of AP treatment outcome over two time periods in our centre,before(2006-2007) and after(2010-2012) the implementation of a CP. The CP comprised the following indicators of quality:performance of all laboratory tests on admission(including lipids and carbohydrate deficient transferrin),determination of AP aetiology,abdomen ultrasound(US) within the first 24 h after admission,contrast-enhanced computed tomography of the abdomen in all cases of suspected pancreatic necrosis,appropriately selected and sufficiently used antibiotic therapy(if necessary),pain control,adequate hydration,control of haemodynamic parameters and transfer to the Intensive Care Unit(ICU)(if necessary),endoscopic retrograde cholangiopancreatography(ERCP) in biliary AP,surgical treatment(if necessary),and advice on outpatient follow-up after discharge. A comparison of the length of stay with that in other Slovenian hospitals was also performed.RESULTS:There were 139 patients treated in the three-year period after the introduction of a CP,of which 81(58.3%) were male and 58(41.7%) female. The patients' mean age was 59.6 ± 17.3 years. The most common aetiologies were alcoholism and gallstones(38.8% each),followed by unexplained(11.5%),drug-induced,hypertriglyceridemia,post ERCP(2.9% each) and tumours(2.2%). Antibiotic therapy was prescribed in 72(51.8%) patients. Abdominal US was performed in all patients within the first 24 h after admission. Thirty-two(23.0%) patients were treated in the ICU. Four patients died(2.9%). In comparison to 2006-2007,we found an increased number of alcoholic and biliary AP and an associateddecrease in the number of unexplained aetiology cases. The use of antibiotics also significantly decreased after the implementation of a CP(from 70.3% to 51.8%; P = 0.003). There was no statistically significant difference in mortality(1.8% vs 2.9%). The length of stay was significantly shorter when compared to the Slovenian average(P = 0.018).CONCLUSION:The introduction of a CP has improved the treatment of patients with AP,as assessed by all of the observed parameters. | Miroslav Vujasinovic Jana Makuc Bojan Tepes Apolon Marolt Zdenko Kikec Nace Robac | 2015 | World Journal of Gastroenterology2015,21,30: | 13 |

| 8 | Non-invasive diagnosis of liver fibrosis in chronic hepatitis C显示文摘Assessment of liver fibrosis in chronic hepatitis C virus(HCV)infection is considered a relevant part of patient care and key for decision making.Although liver biopsy has been considered the gold standard for staging liver fibrosis,it is an invasive technique and subject to sampling errors and significant intra-and inter-observer variability.Over the last decade,several noninvasive markers were proposed for liver fibrosis diagnosis in chronic HCV infection,with variable performance.Besides the clear advantage of being noninvasive,a more objective interpretation of test results may overcome the mentioned intra-and inter-observer variability of liver biopsy.In addition,these tests can theoretically offer a more accurate view of fibrogenic events occurring in the entire liver with the advantage of providing frequent fibrosis evaluation without additional risk.However,in general,these tests show low accuracy in discriminating between intermediate stages of fibrosis and may be influenced by several hepatic and extrahepatic conditions.These methods are either serum markers(usually combined in a mathematical model)or imaging modalities that can be used separately or combined in algorithms to improve accuracy.In this review we will discuss the different noninvasive methods that are currently available for the evaluation of liver fibrosis in chronic hepatitis C,their advantages,limitations and application in clinical practice. | Leonardo de Lucca Schiavon Janaína Luz Narciso-Schiavon Roberto José de Carvalho-Filho | 2014 | World Journal of Gastroenterology2014,20,11: | 11 |
| 9 | Autoantibodies in chronic hepatitis C: A clinical perspective显示文摘Non-organ-specific autoantibodies and thyroid autoantibodies have been frequently found in chronic carriers of hepatitis C virus(HCV). With respect to endomysial antibodies and tissue transglutaminase, it is controversial whether the prevalence of glutenrelated seromarkers is higher in patients with HCV. In such cases, in addition to acknowledging any currently existing autoimmune disease, recognizing the risk of the patient developing an autoimmune disease during interferon(IFN)-based treatment must be a principle concern. From a clinical point-of-view, the presence of autoantibodies arouses suspicion that an autoimmunedisease may be present or may be precipitated by IFNbased HCV treatment. In this paper, we review the prevalence of autoantibodies in individuals with hepatitis C, the clinical significance of these autoantibodies, and the approach recommended for such situations. | Janaína Luz Narciso-Schiavon Leonardo de Lucca Schiavon | 2015 | World Journal of Hepatology2015,7,8: | 11 |
| 10 | Matrix metalloproteinases and gastrointestinal cancers: Impacts of dietary antioxidants显示文摘The process of carcinogenesis is tightly regulated by antioxidant enzymes and matrix degrading enzymes, namely, matrix metalloproteinases(MMPs). Degradation of extracellular matrix(ECM) proteins like collagen, proteoglycan, laminin, elastin and fibronectin is considered to be the prerequisite for tumor invasion and metastasis. MMPs can degrade essentially all of the ECM components and, most MMPs also substantially contribute to angiogenesis, differentiation, proliferation and apoptosis. Hence, MMPs are important regulators of tumor growth both at the primary site and in distant metastases; thus the enzymes are considered as important targets for cancer therapy. The implications of MMPs in cancers are no longer mysterious; however, the mechanism of action is yet to be explained. Herein, our major interest is to clarify how MMPs are tied up with gastrointestinal cancers. Gastrointestinal cancer is a variety of cancer types, including the cancers of gastrointestinal tract and organs, i.e., esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum and anus. The activity of MMPs is regulated by its endogenous inhibitor tissue inhibitor of metallopro-teinase(TIMP) which bind MMPs with a 1:1 stoichiometry. In addition, RECK(reversion including cysteinerich protein with kazal motifs) is a membrane bound glycoprotein that inhibits MMP-2,-9 and-14. Moreover, α2-macroglobulin mediates the uptake of several MMPs thereby inhibit their activity. Cancerous conditions increase intrinsic reactive oxygen species(ROS) through mitochondrial dysfunction leading to altered protease/anti-protease balance. ROS, an index of oxidative stress is also involved in tumorigenesis by activation of different MAP kinase pathways including MMP induction. Oxidative stress is involved in cancer by changing the activity and expression of regulatory proteins especially MMPs. Epidemiological studies have shown that high intake of fruits that rich in antioxidants is associated with a lower cancer incidence. Evidence indicates that some antioxidants inhibit the growth of malignant cells by inducing apoptosis and inhibiting the activity of MMPs. This review is discussed in six subchapters, as follows. | Sugreev Verma Kousik Kesh Nilanjan Ganguly Sayantan Jana Snehasikta Swarnakar | 2014 | World Journal of Biological Chemistry2014,5,3: | 10 |
| 11 | Pancreatic exocrine insufficiency, diabetes mellitus and serum nutritional markers after acute pancreatitis显示文摘AIM:To investigate impairment and clinical significance of exocrine and endocrine pancreatic function in patients after acute pancreatitis(AP).METHODS:Patients with AP were invited to participate in the study.Severity of AP was determined by the Atlanta classification and definitions revised in2012.Pancreatic exocrine insufficiency(PEI)was diagnosed by the concentration of fecal elastase-1.An additional work-up,including laboratory testing of serum nutritional markers for determination ofmalnutrition,was offered to all patients with low levels of fecal elastase-1 FE.Hemoglobin A1c or oral glucose tolerance tests were also performed in patients without prior diabetes mellitus,and type 3c diabetes mellitus(T3c DM)was diagnosed according to American Diabetes Association criteria.RESULTS:One hundred patients were included in the study:75%(75/100)of patients had one attack of AP and 25%(25/100)had two or more attacks.The most common etiology was alcohol.Mild,moderately severe and severe AP were present in 67,15 and 18%of patients,respectively.The mean time from attack of AP to inclusion in the study was 2.7 years.PEI was diagnosed in 21%(21/100)of patients and T3c DM in14%(14/100)of patients.In all patients with PEI,at least one serologic nutritional marker was below the lower limit of normal.T3c DM was more frequently present in patients with severe AP(P=0.031),but was also present in some patients with mild and moderately severe AP.PEI was present in all degrees of severity of AP.There were no statistically significantly differences according to gender,etiology and number of AP attacks.CONCLUSION:As exocrine and endocrine pancreatic insufficiency can develop after AP,routine follow-up of patients is necessary,for which serum nutritional panel measurements can be useful. | Miroslav Vujasinovic Bojan Tepes Jana Makuc Sasa Rudolf Jelka Zaletel Tjasa Vidmar Maja Seruga Bostjan Birsa | 2014 | World Journal of Gastroenterology2014,20,48: | 10 |
| 12 | Signaling networks in immunometabolism显示文摘Adaptive immunity is essential for pathogen and tumor eradication,but may also trigger uncontrolled or pathological inflammation.T cell receptor,co-stimulatory and cytokine signals coordinately dictate specific signaling networks that trigger the activation and functional programming of T cells.In addition,cellular metabolism promotes T cell responses and is dynamically regulated through the interplay of serine/threonine kinases,immunological cues and nutrient signaling networks.In this review,we summarize the upstream regulators and signaling effectors of key serine/threonine kinase-mediated signaling networks,including PI3K-AGC kinases,mTOR and LKB1-AMPK pathways that regulate metabolism,especially in T cells.We also provide our perspectives about the pending questions and clinical applicability of immunometabolic signaling.Understanding the regulators and effectors of immunometabolic signaling networks may uncover therapeutic targets to modulate metabolic programming and T cell responses in human disease. | Jordy Saravia Jana L.Raynor Nicole M.Chapman Seon Ah Lim Hongbo Chi | 2020 | Cell Research2020,30,4: | 9 |
| 13 | Blood pressure and stature in Helicobacter pylori positive and negative persons显示文摘To evaluate vital signs and body indices in Helicobacter pylori(H.pylori)positive and negative persons.A total of 22 centres entered the study.They were spread over the whole country,corresponding well to the geographical distribution of the Czech population.A total of 1818 subjects(aged 5-98 years)took part in the study,randomly selected out of 38147 subjects.H.pylori infection was investigated by means of a 13Curea breath test.Data on height,weight,systolic and diastolic blood pressure and heart rate were collected at the clinics of general practitioners.The overall prevalence of H.pylori infection was 30.4%(402/1321)in adults(≥18 year-old)and 5.2%(26/497)in children and adolescents(≤17 year-old).Once adjusted for age and gender,only a difference in body mass index remained statistically significant with H.pylori positive adults showing an increase of 0.6 kg/m2 in body mass index.Once adjusted for age and gender,we found a difference in height between H.pylori positive and H.pylori negative children and adolescents.On further adjustment for place of residence,this difference became statistically significant,with H.pylori positive children and adolescents being on average 3.5 cm shorter.H.pylori positive adults were significantly older compared to H.pylori negative subjects.Once adjusted for age and gender,H.pylori infection had no impact on body weight,body mass index and vital signs either in adults or children and adolescents.Chronic H.pylori infection appeared to be associated with short stature in children.H.pylori infection did not influence blood pressure,body weight and body mass index either in adults or children and adolescents. | Marcela Kopacova Ilona Koupil Bohumil Seifert Miluska Skodova Fendrichova Jana Spirkova Viktor Vorisek Stanislav Rejchrt Tomas Douda Ilja Tacheci Jan Bures | 2014 | World Journal of Gastroenterology2014,20,19: | 9 |

| 16 | Significant decrease in prevalence ofHelicobacter pylori in the Czech Republic显示文摘AIM:To study possible decrease in prevalence of Helicobacter pylori(H.pylori) infection in the Czech Republic within a 10-year period.METHODS:A total of 22 centres entered the study.The catchment areas of these centres covered cities and towns with more than 20 000 inhabitants,smaller towns(≤ 20 000 inhabitants) with surrounding villages and rural areas,and were spread over the whole country,corresponding well to the geographical distribution of the Czech population.A total of 1 837 subjects(aged 5-98 years) took part in the study,randomly selected out of 38 147 people from the general population.H.pylori infection was investigated by means of a 13 C-urea breath test.Breath samples in duplicates were analysed using isotope ratio mass spectrometry.The cut-off point was 3.5.Social and demographic characteristics were based on data from self-completed questionnaires.RESULTS:The overall prevalence of H.pylori infection was 23.5%(430/1826),and 4.8%(20/420) in children aged 15 or less.There was no statistically significant difference in prevalence between males(24.3%;208/857) and females(22.9%,222/969,P = 0.494).H.pylori infection was strongly associated with higher age,among subjects aged 55+ years,prevalence of H.pylori infection was 39.8%(252/633,P < 0.001).The highest prevalence of H.pylori infection was found among persons aged 55-64 years(43.9%,97/221) and 75+ years(37.9%,58/153).Among study subjects aged 15+ years,prevalence of H.pylori infection was significantly increased in those with lowest education(odds risk 3.19,95% CI 1.87-5.47).Compared to never married(14.1%),the prevalence of H.pylori infection was statistically significantly higher among married(35.4%,246/694,P < 0.001),divorced(36.8%,49/133,P < 0.001) and widowed study subjects(40.2%,45/112,P < 0.001),both in minimally and fully adjusted analysis.There was no significant difference in the prevalence of H.pylori infection between married and widowed subjects(35.4%,246/694 vs 40.2%,45/112,P = 0.389).There was little variation in smoking prevalence across categories of smoking and there was no evidence of an increased risk ofH.pylori infection among current or past smokers in our data(odds risk 1.04 with 95% CI 0.78-1.40 for current smokers;odds ratio 0.83 with 95% CI 0.60-1.16 for former smokers).The current prevalence of H.pylori in 2011 was significantly lower compared to the prevalence reported from identical geographical areas in 2001(23.5%vs 41.7%,P < 0.001).CONCLUSION:The overall prevalence of H.pylori infection in the general population has fallen substantially in the Czech Republic over the past 10 years. | Jan Bure Marcela Kopáová Ilona Koupil Bohumil Seifert Miluka kodová Fendrichová Jana pirková Viktor Voíek Stanislav Rejchrt TomáDouda Norbert Král Ilja Tachecí | 2012 | World Journal of Gastroenterology2012,18,32: | 8 |
| 17 | Magnetic resonance imaging in glenohumeral instability显示文摘The glenohumeral joint is the most commonly dislocated joint of the body and anterior instability is the most common type of shoulder instability.Magnetic resonance (MR) imaging,and more recently,MR arthrography,have become the essential investigation modalities of glenohumeral instability,especially for pre-procedure evaluation before arthroscopic surgery.Injuries associated with glenohumeral instability are variable,and can involve the bones,the labor-ligamentous components,or the rotator cuff.Anterior instability is associated with injuries of the anterior labrum and the anterior band of the inferior glenohumeral ligament,in the form of Bankart lesion and its variants;whereas posterior instability is associated with reverse Bankart and reverse Hill-Sachs lesion.Multidirectional instability often has no labral pathology on imaging but shows specific osseous changes such as increased chondrolabral retroversion.This article reviews the relevant anatomy in brief,the MR imaging technique and the arthrographic technique,and describes the MR findings in each type of instability as well as common imaging pitfalls. | Manisha Jana Shivanand Gamanagatti | 2011 | World Journal of Radiology2011,3,9: | 7 |
