| 1 | Helicobacter pylori infection as a cause of iron deficiency anaemia of unknown origin显示文摘AIM: To assess the aetiological role of Helicobacter pylori (H. pylori) infection in adult patients with ironrefractory or iron-dependent anaemia of previously unknown origin. METHODS: Consecutive patients with chronic irondeficient anaemia (IDA) with H. pylori infection and a negative standard work-up were prospectively evaluated. All of them had either iron refractoriness or iron dependency. Response to H. pylori eradication was assessed at 6 and 12 mo from follow-up. H. pylori infection was considered to be the cause of the anaemia when a complete anaemia resolution without iron supplements was observed after eradication. RESULTS: H. pylori was eradicated in 88 of the 89 patients. In the non-eradicated patient the four eradicating regimens failed. There were violations of protocol in 4 patients, for whom it was not possible to ascertain the cause of the anaemia. Thus, 84 H. pylori eradicated patients (10 men; 74 women) were available to assess the effect of eradication on IDA. H. pylori infection was considered to be the aetiology of IDA in 32 patients (38.1%; 95%CI: 28.4%-48.8%). This was more frequent in men/postmenopausal women than in premenopausal women (75% vs 23.3%; P < 0.0001) with an OR of 9.8 (95%CI: 3.3-29.6). In these patients, anaemia resolution occurred in the first follow-up visit at 6 mo, and no anaemia or iron deficiency relapse was observed after a mean follow-up of 21 ± 2 mo. CONCLUSION: Gastric H. pylori infection is a frequent cause of iron-refractory or iron-dependent anaemia of previously unknown origin in adult patients. | Helena Monzón Montserrat Forné Maria Esteve Mercé Rosinach Carme Loras Jorge C Espinós Josep M Viver Antonio Salas Fernando Fernández-Baares | 2013 | World Journal of Gastroenterology2013，19，26： | 13 |

| 3 | Inorganic arsenic: A non-genotoxic carcinogen显示文摘Inorganic arsenic induces a variety of toxicities including cancer. The mode of action for cancer and non-cancer effects involves the metabolic generation of trivalent arsenicals and their reaction with sulfhydryl groups within critical proteins in various cell types which leads to the biological response. In epithelial cells, the response is cell death with consequent regenerative proliferation. If this continues for a long period of time, it can result in an increased risk of cancer. Arsenicals do not react with DNA. There is evidence for indirect genotoxicity in various in vitro and in vivo systems, but these involve exposures at cytotoxic concentrations and are not the basis for cancer development. The resulting markers of genotoxicity could readily be due to the cytotoxicity rather than an effect on the DNA itself. Evidence for genotoxicity in humans has involved detection of chromosomal aberrations, sister chromatid exchanges in lymphocytes and micronucleus formation in lymphocytes, buccal mucosal cells, and exfoliated urothelial cells in the urine. Numerous difficulties have been identified in the interpretation of such results, including inadequate assessment of exposure to arsenic, measurement of micronuclei, and potential confounding factors such as tobacco exposure, folate deficiency, and others. Overall, the data strongly supports a non-linear dose response for the effects of inorganic arsenic. In various in vitro and in vivo models and in human epidemiology studies there appears to be a threshold for biological responses, including cancer. | Samuel M.Cohen Aparajita Chowdhury Lora L.Arnold | 2016 | Journal of Environmental Sciences2016，28，11： | 7 |
| 4 | Management of psoriasis patients with hepatitis B or hepatitis C virus infection显示文摘The systemic therapies available for the management of Psoriasis(PsO) patients who cannot be treated with more conservative options, such as topical agents and/or phototherapy, with the exception of acitretin, can worsen or reactivate a chronic infection. Therefore, before administering immunosuppressive therapies with either conventional disease-modifying drugs(c DMARDs) or biological ones(b DMARDs) it is mandatory to screen patients for some infections, including hepatitis B virus(HBV) and hepatitis C virus(HCV). In particular, the patients eligible to receive an immunosuppressive drug must be screened for the following markers: antibody to hepatitis B core, antibody to hepatitis B surface antigen(anti-HBs Ag), HBs Ag, and antibody to HCV(anti-HCV). In case HBV or HCV infection is diagnosed, a close collaboration with a consultant hepatologist is needed before and during an immunosuppressive therapy. Concerning therapy with immunosuppressive drugs in PsO patients with HBV or HCV infection, data exist mainly for cyclosporine a(Cy A) or b DMARDs(etanercept, adalimumab, infliximab, ustekinumab). The natural history of HBV and HCV infection differs significantly as well as the effect of immunosuppression on the aforementioned infectious diseases. As a rule, in the case of active HBV infection, systemic immunosuppressive antipsoriatic therapies must be deferred until the infection is controlled with an adequate antiviral treatment. Inactive carriers need to receive antiviral prophylaxis 2-4 wk before starting immunosuppressive therapy, to be continued after 6-12 mo from its suspension. Due to the risk of HBV reactivation, these patients should be monitored monthly for the first 3 mo and then every 3 mo for HBV DNA load together with transaminases levels. Concerning the patients who are occult HBV carriers, the risk of HBV reactivation is very low. Therefore, these patients generally do not need antiviral prophylaxis and the sera HBs Ag and transaminases dosing can be monitored every 3 mo. Concerning PsO patients with chronic HCV infection their management with immunosuppressive drugs is less problematic as compared to those infected by HBV.In fact, HCV reactivation is an extremely rare event after administration of drugs such as CyA or tumor necrosis factor-α inhibitors. As a rule, these patients can be monitored measuring HCV RNA load, and ALT, aspartate transaminase, gamma-glutamyl-transferase, bilirubin, alkaline phosphatase, albumin and platelet every 3-6 mo. The present article provides an updated overview based on more recently reported data on monitoring and managing PsO patients who need systemic antipsoriatic treatment and have HBV or HCV infection as comorbidity. | Claudio Bonifati Viviana Lora Dario Graceffa Lorenzo Nosotti | 2016 | World Journal of Gastroenterology2016，22，28： | 6 |
| 5 | Scoring systems for peptic ulcer bleeding: which one to use?显示文摘AIM To compare the Glasgow-Blatchford score(GBS), Rockall score(RS) and Baylor bleeding score(BBS) in predicting clinical outcomes and need for interventions in patients with bleeding peptic ulcers. METHODS Between January 2008 and December 2013, 1012consecutive patients admitted with peptic ulcer bleeding(PUB) were prospectively followed. The pre-endoscopic RS, BBS and GBS, as well as the post-endoscopic diagnostic scores(RS and BBS) were calculated for all patients according to their urgent upper endoscopy findings. Area under the receiver-operating characteristics(AUROC) curves were calculated for the prediction of lethal outcome, rebleeding, needs for blood transfusion and/or surgical intervention, and the optimal cutoff values were evaluated.RESULTS PUB accounted for 41.9% of all upper gastrointestinal tract bleeding, 5.2% patients died and 5.4% patients underwent surgery. By comparing the AUROC curves of the aforementioned pre-endoscopic scores, the RS best predicted lethal outcome(AUROC 0.82 vs 0.67 vs0.63, respectively), but the GBS best predicted need for hospital-based intervention or 30-d mortality(AUROC0.84 vs 0.57 vs 0.64), rebleeding(AUROC 0.75 vs 0.61 vs 0.53), need for blood transfusion(AUROC 0.83 vs0.63 vs 0.58) and surgical intervention(0.82 vs 0.63 vs 0.52) The post-endoscopic RS was also better than the post-endoscopic BBS in predicting lethal outcome(AUROC 0.82 vs 0.69, respectively).CONCLUSION The RS is the best predictor of mortality and the GBS is the best predictor of rebleeding, need for blood transfusion and/or surgical intervention in patients with PUB. There is no one 'perfect score' and we suggest that these two tests be used concomitantly. | Ivan Budimir Sanja Stojsavljevic Neven Barsic Alen Biscanin Gorana Mirosevic Sven Bohnec Lora Stanka Kirigin Tajana Pavic Neven Ljubicic | 2017 | World Journal of Gastroenterology2017，23，41： | 6 |
| 6 | Does progesterone show neuroprotective effects on traumatic brain injury through increasing phosphorylation of Akt in the hippocampus?显示文摘There are currently no federally approved neuroprotective agents to treat traumatic brain injury. Progesterone, a hydrophobic steroid hormone, has been shown in recent studies to exhibit neuroprotective effects in controlled cortical impact rat models. Akt is a protein kinase known to play a role in cell signaling pathways that reduce edema, inflammation, apoptosis, and promote cell growth in the brain. This study aims to determine if progesterone modulates the phosphorylation of Akt via its threonine 308 phosphorylation site. Phosphorylation at the threonine 308 site is one of several sites responsible for activating Akt and enabling the protein kinase to carry out its neuroprotective effects. To assess the effects of progesterone on Akt phosphorylation, C57BL/6 mice were treated with progesterone(8 mg/kg) at 1(intraperitonally), 6, 24, and 48 hours(subcutaneously) post closed-skull traumatic brain injury. The hippocampus was harvested at 72 hours post injury and prepared for western blot analysis. Traumatic brain injury caused a significant decrease in Akt phosphorylation compared to sham operation. However, mice treated with progesterone following traumatic brain injury had an increase in phosphorylation of Akt compared to traumatic brain injury vehicle. Our findings suggest that progesterone is a viable treatment option for activating neuroprotective pathways after traumatic brain injury. | Richard Justin Garling Lora Talley Watts Shane Sprague Lauren Fletcher David F.Jimenez Murat Digicaylioglu | 2014 | Neural Regeneration Research2014，9，21： | 6 |

| 8 | rate of adverse events of gastroduodenal snare polypectomy for non-flat polyp is low: A prospective and multicenter study显示文摘AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.CONCLUSION Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location. | Henry Córdova Lidia Argüello Carme Loras Antonio Naranjo Rodríguez Faust Riu Pons Joan B Gornals David Nicolás-Pérez Xavier Andújar Murcia Luis Hernández Santos Santolaria Carles Leal Carles Pons Enrique Pérez-Cuadrado-Robles Orlando García-Bosch Michel Papo Berger José Luis Ulla Rocha Cristina Sánchez-Montes Gloria Fernández-Esparrach | 2017 | World Journal of Gastroenterology2017，23，47： | 3 |

| 10 | Translating auxin responses into ovules, seeds and yield: Insight from Arabidopsis and the cereals显示文摘Grain production in cereal crops depends on the stable formation of male and female gametes in the flower.In most angiosperms, the female gamete is produced from a germline located deep within the ovary, protected by several layers of maternal tissue, including the ovary wall,ovule integuments and nucellus. In the field, germline formation and floret fertility are major determinants of yield potential, contributing to traits such as seed number,weight and size. As such, stimuli affecting the timing and duration of reproductive phases, as well as the viability,size and number of cells within reproductive organs can significantly impact yield. One key stimulant is the phytohormone auxin, which influences growth and morphogenesis of female tissues during gynoecium development, gametophyte formation, and endosperm cellularization. In this review we consider the role of the auxin signaling pathway during ovule and seed development, first in the context of Arabidopsis and then in the cereals. We summarize the gene families involved and highlight distinct expression patterns that suggest a range of roles in reproductive cell specification and fate. This is discussed in terms of seed production and how targeted modification of different tissues might facilitate improvements. | Neil J.Shirley Matthew K.Aubert Laura G.Wilkinson Dayton C.Bird Jorge Lora Xiujuan Yang Matthew R.Tucker | 2019 | Journal of Integrative Plant Biology2019，61，3： | 3 |
