| 1 | Influence of proton pump inhibitors on gastritis diagnosis and pathologic gastric changes显示文摘AIM: To investigate the influence of proton pump inhibitors(PPIs) exposure on the diagnosis of Helicobacter pylori(H. pylori) gastritis and intestinal metaplasia.METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed(H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System.RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old(range: 20-87). The histological types of gastritis were classified as H. pylori gastritis(n = 156, 52%) and non-H. pylori gastritis(n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure(71% vs 34.2%, P < 0.001). Intestinal metaplasiawas more likely to be detected in the latter patients(1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure(OR = 0.217, 95%CI: 0.123-0.385), GERD(OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake(OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a significant drop in H. pylori densities and to an increased risk of intestinal metaplasia.CONCLUSION: The use of PPIs masks H. pylori infection, promotes the diagnosis of non-H. pylori inactive chronic gastritis diagnosis, and increases the incidence of intestinal metaplasia. | Soumana C Nasser Mahmoud Slim Jeanette G Nassif Selim M Nasser | 2015 | World Journal of Gastroenterology2015，21，15： | 7 |
| 2 | HepG2 cells support viral replication and gene expression of hepatitis C virus genotype 4 in vitro显示文摘瞄准:与丙肝的长期的复制建立一个房间文化系统病毒(HCV ) 染色体和病毒的抗原的表示在试管内。方法:HepG2 房间线被孵化与长期的丙肝从一个病人与浆液为它的危险性测试到 HCV。房间和上层清液在文化期间在各种各样的时间点被收获。文化上层清液为它感染天真的房间的能力被测试。存在减(反感觉) 在房间的核心和 E1 抗原的 RNA 海滨,和察觉被 RT-PCR 和免疫学的技术(流动血细胞计数和西方的污点) 分别地检验。结果:细胞内部的 HCV RNA 首先在 d 上被检测 3 在感染以后然后能一致地在至少三个月的一个时期上在房间和上层清液被检测。新鲜房间能从有教养的感染的房间感染上层清液。流动 cytometric 分析证明表面和在房子里使用的细胞内部的 HCV 抗原表示使 polyclonal 成为了抗体(反核心,和 anti-E1 ) 。西方的污点分析证明在分子量的产生免疫性的肽的簇的表示在一个月内在 31 和 45 kDa 之间延长了感染的房间的旧文化而这簇在 uninfected HepG2 房间是无法发现的。结论:HepG2 房间线产生 HCV 感染而且支持它的复制在试管内不仅。HCV 结构的蛋白质的表示能在感染的 HepG2 房间被检测。这些房间也能够流病毒的粒子进接着对 uninfected 房间变得传染的培养基。 | Mostafa K El-Awady Ashraf A Tabll Yasmine S El-Abd Mahmoud M Bahgat Hussein A Shoeb Samar S Youssef Noha G Bader El Din El-Rashdy M Redwan Maha El-Demellawy Moataza H Omran Wael T El-Garf Said A Goueli | 2006 | World Journal of Gastroenterology2006，12，30： | 2 |
| 3 | Perioperative risk factors associated with delayed graft function following deceased donor kidney transplantation:A retrospective,single center study显示文摘BACKGROUND There is an abundant need to increase the availability of deceased donor kidney transplantation(DDKT)to address the high incidence of kidney failure.Challenges exist in the utilization of higher risk donor organs into what appears to be increasingly complex recipients;thus the identification of modifiable risk factors associated with poor outcomes is paramount.AIM To identify risk factors associated with delayed graft function(DGF).METHODS Consecutive adults undergoing DDKT between January 2016 and July 2017 were identified with a study population of 294 patients.The primary outcome was the occurrence of DGF.RESULTS The incidence of DGF was 27%.Under logistic regression,eight independent risk factors for DGF were identified including recipient body mass index≥30 kg/m^(2),baseline mean arterial pressure<110 mmHg,intraoperative phenylephrine administration,cold storage time≥16 h,donation after cardiac death,donor history of coronary artery disease,donor terminal creatinine≥1.9 mg/dL,and a hypothermic machine perfusion(HMP)pump resistance≥0.23 mmHg/mL/min.CONCLUSION We delineate the association between DGF and recipient characteristics of preinduction mean arterial pressure below 110 mmHg,metabolic syndrome,donorspecific risk factors,HMP pump parameters,and intraoperative use of phenylephrine. | Nicholas V Mendez Yehuda Raveh Joshua J Livingstone Gaetano Ciancio Giselle Guerra George W Burke III Vadim B Shatz Fouad G Souki Linda J Chen Mahmoud Morsi Jose M Figueiro Tony M Ibrahim Werviston L DeFaria Ramona Nicolau-Raducu | 2021 | World Journal of Transplantation2021，11，4： | 2 |

| 5 | COVID-19 and hepatic injury: cellular and molecular mechanisms in diverse liver cells显示文摘The coronavirus disease 2019(COVID-19)represents a global health and economic challenge.Hepatic injuries have been approved to be associated with severe acute respiratory syndrome coronavirus(SARS-CoV-2)infection.The viral tropism pattern of SARS-CoV-2 can induce hepatic injuries either by itself or by worsening the conditions of patients with hepatic diseases.Besides,other factors have been reported to play a crucial role in the pathological forms of hepatic injuries induced by SARS-CoV-2,including cytokine storm,hypoxia,endothelial cells,and even some treatments for COVID-19.On the other hand,several groups of people could be at risk of hepatic COVID-19 complications,such as pregnant women and neonates.The present review outlines and discusses the interplay between SARS-CoV-2 infection and hepatic injury,hepatic illness comorbidity,and risk factors.Besides,it is focused on the vaccination process and the role of developed vac-cines in preventing hepatic injuries due to SARS-CoV-2 infection. | Fares E M Ali Mostafa K Abd El-Aziz Mahmoud M Ali Osama M Ghogar Adel G Bakr | 2023 | World Journal of Gastroenterology2023，29，3： | 2 |
