| 1 | Comethylation of p16 and MGMT genes in colorectal carcinoma:Correlation with clinicopathological features and prognostic value显示文摘AIM: To investigate the significance of p16 and O6- methylguanine-DNA methyltransferase (MGMT) genes promoter hypermethylation and K-ras mutations on colorectal tumorigenesis and progression. METHODS: p16 and MGMT methylation status was examined on 47 tumor samples, and K-ras mutational status was examined on 85 tumor samples. For methylation analysis, a methylation specific PCR (MS-PCR) method was used. RESULTS: p16 and MGMT promoter methylation was found in 51% (24/47) and 43% (20/47) of CRCs, respectively, and the K-ras mutation was found in 44% (37/85) of CRCs. Comethylation of p16 and MGMT genes was significantly associated with lower aggressiveness of the disease within a two-year period of observation. Only 27% of patients with simultaneous p 16 and MGMT methylation showed the detectible occurrence of metastasis and/or death, compared to 67% of patients without double methylation or with no methylation (3/11 vs 22/33, P < 0.05, χ2-test). In addition, p16 and MGMT comethylation showed a trend toward an association with longer survival in patients with CRCs (35.5 ± 6.0 mo vs 23.1 ± 3.2 mo, P = 0.072, Log-rank test). Progression of the disease within a two-year period was observed in 66% of patients carrying the K-ras mutation, compared to only 19% of patients with wild type K-ras (29/44 vs 7/37, P < 0.001, χ2-test). The presence of the K-ras mutation significantly correlated to shortened overall survival (20.0 ± 1.9 mo vs 37.0 ± 1.8 mo, P < 0.001, Log-rank test). The comethylation of p16 and MGMT genes was significantly associated with lower aggressiveness of the disease even when K-ras mutations were included in the analysis as an independent variable. CONCLUSION: Our data suggest that comethylation of promoters of p 16 and MGMT genes could have a prognostic value in patients with CRC. Specifically, concurrent methylation of both genes correlates with better prognosis. | Koviljka Krtolica Milena Krajnovic Slavica Usaj-Knezevic Dragan Babic Dusan Jovanovic Bogomir Dimitrijevic | 2007 | World Journal of Gastroenterology2007,13,8: | 10 |
| 2 | Increased activity of Pgp multidrug transporter in patients with Helicobacter pylori infection显示文摘AIM: To determine whether local antibiotic resistance involves P-glycoprotein (Pgp)-mediated active drug outpumping during Helicobacter pylori ( H pylori) infection treatment with classic antibiotic therapy. METHODS: Pgp activity was determined in gastric mucosa biopsy specimens obtained from 53 patients with pathohistologically verified gastritis and microbiologically confirmed H pylori infection, and compared with the Pgp activity in 12 control subjects with normal endoscopic findings. TheH pylori positive patients were treated with short-term 7-d therapy consisting of two antibiotics (amoxicillin and azithromycin/metronidazole and clarithromycin) and a proton pump inhibitor. Pgp activity was determined by flow cytometry in the test of rhodamine dye efflux and quantified as mean fluorescence ratio (RMF).RESULTS: Upon the first cycle,H pylori was successfully eradicated in 20 patients, whereas therapy was continued in 33 patients. In the course of antibiotic therapy, RMF increased (P<0.05) and gastric cells showed higher rhodamine dye efflux. The mean pre-treatment RMF values were also higher (P<0.0001) in patients with multiple therapeutic failure than in those with successful H pylorieradication and control subjects.CONCLUSION: Pgp might be one of the causes of therapy failure in patients with H pylori and antibiotic therapy could be chosen and followed up on the basis of the Pgp transporter local activity. | Zarko Babic Ivna Svoboda-Beusan Nastja Kucisec-Tepes Dragan Dekaris Rosana Troskot | 2005 | World Journal of Gastroenterology2005,11,18: | 4 |

| 4 | Carcinosarcoma of the stomach:A case report and review of the literature显示文摘Carcinosarcomas are rare,malignant,biphasic tumors. We report the case of a 62-year-old man with gastric carcinosarcoma,along with its clinical,macroscopic and histopathological features. Macroscopically,a specimen of deformed stomach was obtained that measured 200 mm×150 mm×100 mm. A 150 mm×100 mm× 50 mm exophytic tumoral mass (Borrmann typeⅠ) was found,which involved the posterior wall from the cardia to the antrum. Histopathologically,a mixed type of malignancy was revealed: an adenocarcinoma with intestinal metaplasia,with interposed fascicles of fusiform atypical cells and numerous large,rounded and oval cells. The tumor showed positive histochemistry for cytokeratin 18,epithelial membrane antigen,carcinoembryonic antigen,chromogranin A and vimentin. Liver metastases were diagnosed 8 mo postoperatively,and the patient died 4 mo later. A review of the available literature is also presented. | Tomislav Randjelovic Branka Filipovic Darko Babic Vesna Cemerikic Branislav Filipovic | 2007 | World Journal of Gastroenterology2007,13,41: | 3 |
| 5 | 十五肽BPC157减弱慢性苯丙胺诱导的行为障碍(英文)显示文摘AIM: To investigate the effect of pentadecapeptide BPC 157 on chronic exposure to amphetamine in rats, particularly the changes commonly referred in chronic amphetamine studies as tolerance ( lesser grade of stereotyped behavior, without increased excitability) and reverse tolerance (ie, prominent stereotyped behavior and heightened startle response upon late amphetamine challenges). METHODS: After initial application (initial single dose-regimen), amphetamine (10 mg/kg, ip) was given once daily till d 5 ( continuous administration-regimen), and thereafter on d 8, 16, and 46 (intermittent administration regimen). For stereotyped behavior and heightened startle response the observation period was 120 min after amphetamine application, and each animal was observed for 10 s in 5 min intervals. Pentadecapeptide BPC 157 (10 μg/kg or 10 ng/kg, ip) or saline (5.0 mL/kg, ip) were given only at the beginning of the experiment, simultaneously with the initial dose of amphetamine.
