| 1 | ApoB-100, ApoE and CYP7A1 gene polymorphisms in Mexican patients with cholesterol gallstone disease显示文摘AIM: To determine the possible association of the ApoB100 (Xba Ⅰ ), ApoE (Hha Ⅰ ) and CYP7A1 (Bsa Ⅰ ) gene polymorphisms, with the development of cholesterol gallstone disease (GD) in a Mexican population. METHODS: The polymorphisms were analyzed by polymerase chain reaction followed by restriction fragment length polymorphism, in two groups matched by ethnicity, age and sex: patients with GD (n = 101) and stone-free control subjects (n = 101). RESULTS: Allelic frequencies in patients and controls were: 34.16% vs 41.58% (P = 0.124) for X+of ApoB-100; 4.46% vs 5.94% (P = 0.501) for E2, 85.64% vs 78.22% (P = 0.052) for E3, 9.90% vs 15.84% (P = 0.075) for E4 of ApoE; and 25.74% vs 27.72% (P = 0.653) for C of CYP7A1. Differences in genotypic frequencies between the studied groups were not significant (P < 0.05). CONCLUSION: These results demonstrated that no association exists between the studied polymorphisms and cholelithiasis in this high prevalent population. | Sánchez-Cuén Jaime Aguilar-Medina Maribel Arámbula-Meraz Eliakym Romero-Navarro José Granados Julio Sicairos-Medina Laura Ramos-Payán Rosalío | 2010 | World Journal of Gastroenterology2010，16，37： | 14 |
| 2 | Immune therapy for human papillomaviruses-related cancers显示文摘Human papillomaviruses(HPVs) are a large family of double strand DNA viruses comprising more than 180 types. Infection with HPV is very common and it is associated with benign and malignant proliferation of skin and squamous mucosae. Many HPVs, considered lowrisk such as HPV 6 and 11, produce warts; while highrisk viruses, such as HPVs 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, and 58, induce tumors. About 5% of all cancers in men and women are associated with HPV infection. Because there are not antiviral drugs for HPV infection, current therapies for low-risk HPV infections involve physical removal of the lesion by cryotherapy, trichloracetic acid, laser, or surgical removal. Surgical procedures are effective in the treatment of precancerous lesions, however after these procedures, many recurrences appear due to new re-infections, or to failure of the procedure to eliminate the HPV. In addition, HPV can inhibit recognition of malignant cellsby the immune system, leading to the development of cancer lesions. When this occurs, radiotherapy and chemotherapy are then used. Unfortunately, about 50% of the HPV-cancer patients still die. In the past decade, a better knowledge of the natural history of the virushost interaction and of the immune response against this viral infection has brought new therapeutic strategies geared to modulate the immune system to generate an efficient virus-specific cytotoxic response. Novel HPV protein-expressing vaccines have shown some significant clinical efficacy and systemic HPV-specific cytotoxic T cell responses. This review will describe the current status of the several therapeutic strategies used to treat HPV-induced lesions, and discuss the various new therapies now being tested. | Ricardo Rosales Carlos Rosales | 2014 | World Journal of Clinical Oncology2014，5，5： | 11 |
| 3 | Expression of triggering receptor on myeloid cell 1 and histocompatibility complex molecules in sepsis and major abdominal surgery显示文摘AIM: To evaluate the surface expression of triggering receptor on myeloid cell 1 (TREM-1), class Ⅱ major histocompatibility complex molecules (HLA-DR), andthe expression of the splicing variant (svTREM-1) ofTREM-1 in septic patients and those subjected to major abdominal surgery.METHODS: Using flow cytometry, we examined the surface expression of TREM-1 and HLA-DR in peripheral blood monocytes from 11 septic patients, 7 elective gastrointestinal surgical patients, and 10 healthy volunteers. svTREM-1 levels were analyzed by RT-PCR. RESULTS: Basal expression of TREM-1 and HLA-DR in healthy volunteers was 35.91±14.75 MFI and75.8±18.3%, respectively. In septic patients, TREM-1 expression was 59.9±23.9 MFI and HLA-DR expression was 44.39±20.25%, with a significant differencebetween healthy and septic groups (P<0.05) for bothmolecules. In the surgical patients, TREM-1 and HLA-DR expressions were 56.8±20.85 MFI and 71±13.8% before surgery and 72.65±29.92 MlFI and 72.82±22.55% after surgery. TREM-1 expression was significantly different(P = 0.0087) between the samples before and aftersurgery and svTREM-1 expression was 0.8590±0.1451 MF1, 0.8820±0.1460 MF1, and 2.210±0.7873MF1 in the healthy, surgical (after surgery) and septic groups, respectively. There was a significant difference (P = 0.048) in svTREM-1 expression between the healthy and surgical groups and the septic group.CONCLUSION: TREM-1 expression is increased during systemic inflammatory conditions such as sepsis and the postoperative phase. Simultaneous low expression of HLA-DR molecules correlates with the severity of illness and increases susceptibility to infection. Additionally, TREM-1 expression is distinctly different in surgical patients at different stages of the inflammatory response before and after surgery. Thus, surface TREM-1 appears to be an endogenous signal during the course of the inflammatory response. svTREM-1 expression is significantly increased during sepsis, appearing to be an indicator of severity of illness. Together, these data indicate that TREM-1 may play an important role in establishing and amplifying the systemic inflammatory response. TREM-1, HLA-DR, and svTREM-1 expression analysis can provide useful diagnostic and prognostic indicators during SIRS, CARS, and sepsis. | Nestor González-Roldán Eduardo Ferat-Osorio Rosalía Aduna-Vicente Isabel Wong-Baeza Noemí Esquivel-Callejas Horacio Astudillo-de la Vega Patricio Sánchez-Fernández Lourdes Arriaga-Pizano Miguel Angel Villasís-Keever Constantino López-Macías Armando Isibasi | 2005 | World Journal of Gastroenterology2005，11，47： | 9 |
| 4 | UPLAND EROSION MODELING WITH CASC2D-SED显示文摘Developed at Colorado State University, CASC2D-SED is a physically-based model simulating the hydrologic response of a watershed to a distributed rainfall field. The time-dependent processes include: precipitation, interception, infiltration, surface runoff and channel routing, upland erosion, transport and sedimentation. CASC2D-SED is applied to Goodwin Creek, Mississippi. The watershed covers 21 km2 and has been extensively monitored both at the outlet and at several internal locations by the ARS-NSL at Oxford, MS. The model has been calibrated and validated using rainfall data from 16 meteorological stations, 6 stream gauging stations and 6 sediment gauging stations. Sediment erosion/deposition rates by size fraction are predicted both in space and time. Geovisualization, a powerful data exploration technique based on GIS technology, is used to analyze and display the dynamic output time series generated by the CASC2D-SED model. | Pierre JULIEN Rosalía ROJAS | 2002 | International Journal of Sediment Research2002，17，4： | 7 |
| 5 | Association between Helicobacterpylori, Epstein-Barr virus, human papillomavirus and gastric adenocarcinomas显示文摘AIM To correlate Helicobacter pylori(H. pylori), Epstein-Barr virus(EBV) and human papillomavirus(HPV) with gastric cancer(GC) cases in Pará State, Brazil.METHODS Tissue samples were obtained from 302 gastric adenocarcinomas. A rapid urease test was used to detect the presence of H. pylori, and the presence of the cagA gene in the HP-positive samples was confirmed by PCR. An RNA in situ hybridization test designed to complement Eber1 RNA was used to detect the presence of EBV in the samples, and the L1 region of HPV was detected using nested PCR. Positive HPV samples were genotyped and analyzed for E6 and E7 viral gene expression. Infections were also correlated with the clinical and pathological characteristics of the patients.RESULTS The majority of the 302 samples analyzed were obtained from men(65%) aged 55 years or older(67%) and were classified as the intestinal subtype(55%). All three pathogens were found in the samples analyzed in the present study(H. pylori : 87%, EBV: 20%, HPV: 3%). Overall, 78% of the H. pylori-positive(H. pylori+) samples were cag A +(H. pylori-cag A+), and there was an association between the cytotoxic product of this gene and EBV. Coinfections of H. pylori-cagA+ and EBV were correlated with the most advanced tumor stages. Although only 20% of the tumors were positive for EBV, infection with this virus was associated with distant metastasis. Only the HPV 16 and 18 strains were found in the samples, although no expression of the E6 and E7 oncoproteins was detected. The fundus of the stomach was the region least affected by the pathogens.CONCLUSION HPV was not involved in gastric tumorigenesis. Prophylactic and therapeutic measures against H. pylori and EBV may prevent the development of GC, especially the more aggressive forms. | Carolina Rosal Teixeira de Souza Marcelli Carolini Alves Almeida Andre Salim Khayat Emerson Lucena da Silva Paulo Cardoso Soares Luiz Claudio Chaves Rommel Mario Rodriguez Burbano | 2018 | World Journal of Gastroenterology2018，24，43： | 6 |
| 6 | Fatty liver disease,an emerging etiology of hepatocellular carcinoma in Argentina显示文摘AIM To investigate any changing trends in the etiologies of hepatocellular carcinoma(HCC) in Argentina during the last years. METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications. | Federico Pinero Josefina Pages Sebastián Marciano Nora Fernández Jorge Silva Margarita Anders Alina Zerega Ezequiel Ridruejo Beatriz Ameigeiras Claudia D’Amico Luis Gaite Carla Bermúdez Manuel Cobos Carlos Rosales Gustavo Romero Lucas McCormack Virginia Reggiardo Luis Colombato Adrián Gadano Marcelo Silva | 2018 | World Journal of Hepatology2018，10，1： | 4 |
