| 1 | Changes in lipid metabolism in chronic hepatitis C显示文摘AIM: To investigate the relationship between certain biochemical parameters of lipid metabolism in the serum and steatosis in the liver.METHODS: The grade of steatosis (0-3) and histological activity index (HAI, 0-18) in liver biopsy specimens were correlated with serum alanine aminotransferase (ALT), total cholesterol and triglyceride levels in 142 patients with chronic hepatitis C (CH-C), and 28 patients with non-alcoholic fatty liver disease (NAFLD) without hepatitis C virus (HCV) infection. The serum parameters were further correlated with 1 797 age and sex matched control patients without any liver diseases.RESULTS: Steatosis was detected in 90 out of 142 specimens (63%) with CH-C. The ALT levels correlated with the grade of steatosis, both in patients with CH-C and NAFLD (P<0.01). Inserting the score values of steatosis as part of the HAI, correlation with the ALT level (P<0.00001) was found. The triglyceride and cholesterol levels were significantly lower in patients with CH-C (with and without steatosis), compared to the NAFLD group and to the virus-free control groups.CONCLUSION: Our study confirms the importance of liver steatosis in CH-C which correlates with lower lipid levels in the sera. Inclusion of the score of steatosis into HAI, in case of CH-C might reflect the alterations in the liver tissue more precisely, while correlating with the ALT enzyme elevation. | Katalin Jármay Gizella Karácsony András Nagy Zsuzsa Schaff | 2005 | World Journal of Gastroenterology2005，11，41： | 22 |
| 2 | Portal vein thrombosis and arterioportal shunts:Effects on tumor response after chemoembolization of hepatocellular carcinoma显示文摘AIM: To evaluate the effect of portal vein thrombosis and arterioportal shunts on local tumor response in advanced cases of unresectable hepatocellular carcinoma treated by transarterial chemoembolization. METHODS: A retrospective study included 39 patients (mean age: 66.4 years, range: 45-79 years, SD: 7) with unresectable hepatocellular carcinoma (HCC) who were treated with repetitive transarterial chemoembolization (TACE) in the period between March 2006 and October 2009. The effect of portal vein thrombosis (PVT) (in 19 out of 39 patients), the presence of arterioportal shunt (APS) (in 7 out of 39), the underlying liver pathology,Child-Pugh score, initial tumor volume, number of tumors and tumor margin definition on imaging were correlated with the local tumor response after TACE. The initial and end therapy local tumor responses were evaluated according to the response evaluation criteria in solid tumors (RECIST) and magnetic resonance imaging volumetric measurements. RESULTS: The treatment protocols were well tolerated by all patients with no major complications. Local tumor response for all patients according to RECIST criteria were partial response in one patient (2.6%), stable disease in 34 patients (87.1%), and progressive disease in 4 patients (10.2%). The MR volumetric measurements showed that the PVT, APS, underlying liver pathology and tumor margin definition were statistically significant prognostic factors for the local tumor response (P = 0.018, P = 0.008, P = 0.034 and P = 0.001, respectively). The overall 6-, 12- and 18-mo survival rates from the initial TACE were 79.5%, 37.5% and 21%, respectively. CONCLUSION: TACE may be exploited safely for palliative tumor control in patients with advanced unresectable HCC; however, tumor response is significantly affected by the presence or absence of PVT and APS. | Thomas J Vogl Nour-Eldin Nour-Eldin Sally Emad-Eldin Nagy NN Naguib Joerg Trojan Hans Ackermann Omar Abdelaziz | 2011 | World Journal of Gastroenterology2011，17，10： | 20 |
| 3 | Interplay between nitric oxide and VIP in CCK-8-induced phasic contractile activity in the rabbit sphincter of Oddi显示文摘AIM: The sphincter of Oddi (SO) plays an important role in delivery of bile into the duodenum. To establish whether vasoactive intestinal polypeptide (VIP) and nitric oxide (NO) were involved in phasic contractile activity of the rabbit SO stimulated by cholecystokinin-octapeptide (CCK-8).METHODS: Isolated SO muscle rings were cleaned of fat and mounted horizontally on two small L-shaped hooksone of which was connected to a force transducer for the measurement of isometric tension. The experiments were carried out in a thermostatically controlled (37±0.2℃)organ bath (5 mL) containing Krebs solution. The organ fluid was gassed with 95% O2 and 50 mL/L CO2 to keep the pH at 7.40±0.05. Contractile responses to CCK-8 (1μmol/L) were evaluated in the presence and absence of N^G-nitro-L-arginine (LNNA), an inhibitor of NO synthase (100μmol/L), and (p-chloro-D-Phe^6-Leu^17)-VIP (VIPa,30μmol/L), a VIP receptor antagonist.RESULTS: CCK-8 stimulated the phasic activity of the SO.NO synthase inhibition increased the frequency and amplitude of contractions with a slight increase in developed tension.Pre-incubation with VIPa also attenuated this CCK-8 effect.The combined application of LNNA and VIPa abolished the phasic activity of the muscle rings with a marked increase in tension in response to CCK-8.CONCLUSION: VIP and NO together contribute to an increase in phasic activity of SO. | Attila Pálv(o|¨)lgyi Réka Sári József Németh Annamária Szabolcs István Nagy Péter Hegyi János Lonovics Zoltán Szilvássy | 2005 | World Journal of Gastroenterology2005，11，21： | 11 |

| 5 | Trans-arterial chemoperfusion for the treatment of liver metastases of breast cancer and colorectal cancer: Clinical results in palliative care patients显示文摘AIM To evaluate the clinical value and efficiency of transarterial chemoperfusion(TACP) in patients with liver metastases from breast cancer(BC) and colorectal cancer(CRC).METHODS We treated 36 patients with liver metastases of BC(n = 19, 19 females) and CRC(n = 17; 8 females, 9 males) with repeated TACP. The treatment interval was 4 wk. TACP was performed with gemcitabine(1000 mg/m2) and mitomycin(10 mg/m2), administered within 1 h after positioning the catheter tip in the hepatic artery. Before treatment, the size, location, tumour volume, vascularization and number of liver tumours were evaluated using magnetic resonance imaging(MRI). Tumour response was evaluated according to the Response Evaluation Criteria in Solid Tumors guidelines.RESULTS TACP using gemcitabine and mitomycin for metastases from CRC and BC was performed without any serious side effects. The follow-up MRI showed a therapeutic response in 84.2% of the BC patients-stable disease 47.4% and partial response 36.8%. A progression was seen in 15.8%.CRC patients showed a therapeutic response in 52.9% of cases. A progression of the disease was documented in 47.1% of the patients with CRC. These data show that TACP in patients with liver metastases of BC leads to a significantly better therapeutic response compared with CRC patients(P = 0.042). The median survival time was 13.2 mo for the BC patients, which is significantly longer than for CRC patients at 9.3 mo(P = 0.001).CONCLUSION TACP for liver metastases of BC appears to be a safe and effective palliative treatment with improved outcomes in comparison to patients with CRC. | Tatjana Gruber-Rouh Marcel Langenbach Nagy NN Naguib Nour-Eldin M Nour-Eldin Thomas J Vogl Stephan Zangos Martin Beeres | 2017 | World Journal of Clinical Oncology2017，8，4： | 7 |
| 6 | No difference in mortality among ALPPS,two-staged hepatectomy,and portal vein embolization/ligation:A systematic review by updated traditional and network meta-analyses显示文摘Background:There is an ongoing debate on the feasibility,safety,and oncological efficacy of the associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)technique.The aim of this study was to compare ALPPS,two-staged hepatectomy(TSH),and portal vein embolization(PVE)/ligation(PVL)using updated traditional meta-analysis and network meta-analysis(NMA).Data sources:Electronic databases were used in a systematic literature search.Updated traditional metaanalysis and NMA were performed and compared.Mortality and major morbidity were selected as primary outcomes.Results:Nineteen studies including 1200 patients were selected from the pool of 436 studies.Of these patients,315(31%)and 702(69%)underwent ALPPS and portal vein occlusion(PVO),respectively.Ninetyday mortality based on updated traditional meta-analysis,subgroup analysis of the randomized controlled trials(RCTs),and both Bayesian and frequentist NMA did not demonstrate significant differences between the ALPPS cohort and the PVE,PVL,and TSH cohorts.Moreover,analysis of RCTs did not demonstrate significant differences of major morbidity between the ALPPS and PVO cohorts.The ALPPS cohort demonstrated significantly more favorable outcomes in hypertrophy parameters,time to operation,definitive hepatectomy,and R0 margins rates compared with the PVO cohort.In contrast,1-year disease-free survival was significantly higher in the PVO cohort compared to the ALPPS cohort.Conclusions:This study is the first to use updated traditional meta-analysis and both Bayesian and frequentist NMA and demonstrated no significant differences in 90-day mortality between the ALPPS and other hepatic hypertrophy approaches.Furthermore,two high quality RCTs including 147 patients demonstrated no significant differences in major morbidity between the ALPPS and PVO cohorts. | Paschalis Gavriilidis Robert P Sutcliffe Keith J Roberts Madhava Pai Duncan Spalding Nagy Habib Long R Jiao Mikael H Sodergren | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，5： | 6 |
| 7 | Alpha-fetoprotein expression is a potential prognostic marker in hepatocellular carcinoma显示文摘AIM: To characterize the alpha-fetoprotein (AFP) positive and negative hepatocellular carcinoma (HCC) samples.METHODS: Thirty-seven paraffin-embedded human HCC samples were analyzed by immunohistochemistry for the following antigens: AFP, β-catenin, p53, CD44, MSH-2,MLH-1, and HNF-4. The tumors were divided into two groups based on the AFP expression. The immunophenotypic data and important clinical parameters were studied between the two groups.RESULTS: Twenty-one of the thirty-seven examined HCCs were AFP positive. Seven with nuclear p53 staining were AFP positive, while seven tumors with nuclear β-catenin staining were AFP negative. CD44 staining and high histological tumor grade were more frequent among the AFP-positive HCCs. The other immunophenotypical and dinical parameters did not show statistically significant difference in their distribution between the AFP positive and negative samples.CONCLUSION: AFP expression in HCC correlates with unfavorable prognostic factors, while nuclear β-catenin positivity is more common among the AFP-negative liver tumors. This observation supports the microarray data onin vivo human tumors. | Dénes Grg János Regly-Mérei Sándor Paku László Kopper Péter Nagy | 2005 | World Journal of Gastroenterology2005，11，32： | 6 |
| 8 | Clinical significance of granuloma in Crohn's disease显示文摘AIM: Granuloma is considered the hallmark of microscopic diagnosis in Crohn's disease (CD), but granulomas can be detected in only 21-60% of CD patients. The aim of this studywas to evaluate the frequency of granulomas by multiple endoscopic biopsies in patients with CD and to examine whether group of patients with or without granuloma exhibit a different clinical course.METHODS: Fifty-six patients with newly diagnosed Cdwere included in the study. Jejunoscopy, enteroclysis and ileo-colonoscopy were performed in all patients. At least two biopsy specimens from each examined gastrointestinal segment were examined microscopically searching granuloma. The clinical course was followed in all patients, and extraintestinal manifestations as well as details of any immunosuppressive therapy and surgical intervention were noted.RESULTS: Granuloma was found in 44.6% of the cases (25 patients). Patients with granuloma had higher activity parameters at the time of the biopsies. Extraintestinal manifestations were observed and surgical interventions were performed more often in the granuloma group. The need of immunosuppressive therapy was significantly more frequent in the patients with granuloma. Granuloma formation is more often seen in younger patients, and mainly in the severe, active penetrating disease. CONCLUSION: The significantly higher frequency of surgical interventions and immunosuppressive therapy suggests that granuloma formation is associated with a more severe disease course during the first years of CD. | Tamás Molnár László Tiszlavicz Csaba Gyulai Ferenc Nagy János Lonovics | 2005 | World Journal of Gastroenterology2005，11，20： | 5 |
| 9 | CYP24A1 inhibition facilitates the anti-tumor effect of vitamin D3 on colorectal cancer cells显示文摘AIM:The effects of vitamin D3 have been investigated on various tumors, including colorectal cancer (CRC). 25-hydroxyvitamin-D3-24-hydroxylase (CYP24A1), the enzyme that inactivates the active vitamin D3 metabolite 1,25-dihydroxyvitamin D3 (1,25-D3), is considered to be the main enzyme determining the biological halflife of 1,25-D3. During colorectal carcinogenesis, the expression and concentration of CYP24A1 increases significantly, suggesting that this phenomenon could be responsible for the proposed efficacy of 1,25-D3 in the treatment of CRC. The aim of this study was to investigate the anti-tumor effects of vitamin D3 on the human CRC cell line Caco-2 after inhibition of the cytochrome P450 component of CYP24A1 activity. METHODS:We examined the expression of CYP24A1 mRNA and the effects of 1,25-D3 on the cell line Caco-2 after inhibition of CYP24A1. Cell viability and proliferation were determined by means of sulforhodamine-B staining and bromodeoxyuridine incorporation, respectively, while cytotoxicity was estimated via the lactate dehydrogenase content of the cell culture supernatant. CYP24A1 expression was measured by realtime reverse transcription polymerase chain reaction. A number of tetralone compounds were synthesized to investigate their CP24A1 inhibitory activity. RESULTS:In response to 1,25-D3, CYP24A1 mRNA expression was enhanced significantly, in a time- and dose-dependent manner. Caco-2 cell viability and proliferation were not influenced by the administration of 1,25-D3 alone, but were markedly reduced by coadministration of 1,25-D3 and KD-35, a CYP24A1-inhibiting tetralone. Our data suggest that the mechanism of action of co-administered KD-35 and 1,25-D3 does not involve a direct cytotoxic effect, but rather the inhibition of cell proliferation. CONCLUSION:These findings demonstrate that the selective inhibition of CYP24A1 by compounds such as KD-35 may be a new approach for enhancement of the anti-tumor effect of 1,25-D3 on CRC. | János P Kósa Péter Horváth János Wlfling Dóra Kovács Bernadett Balla Péter Mátyus Evelin Horváth Gábor Speer István Takács Zsolt Nagy Henrik Horváth Péter Lakatos | 2013 | World Journal of Gastroenterology2013，19，17： | 5 |
| 10 | Efficacy of 6-mercaptopurine treatment after azathioprine hypersensitivity in inflammatory bowel disease显示文摘AIM:To investigate the efficacy of 6-mercaptopurine (6-MP) in cases of azathioprine (AZA) hypersensitivity in patients with inflammatory bowel disease. METHODS: Twenty nine previously confirmed Crohn’s disease (CD) (n = 14) and ulcerative colitis (UC) (n = 15) patients with a known previous (AZA) hypersensitivity reaction were studied prospectively. The 6-MP doses were gradually increased from 0.5 up to 1.0-1.5 mg/kg per day. Clinical activity indicies (CDAI/CAI), laboratory variables and daily doses of oral 5-ASA, corticosteroids, and 6-MP were assessed before and in the first, sixth and twelfth months of treatment. RESULTS: In 9 patients, 6-MP was withdrawn in the first 2 wk due to an early hypersensitivity reaction. Medication was ineffective within 6 mo in 6 CD patients, and myelotoxic reaction was observed in two. Data were evaluated at the end of the sixth month in 12 (8 UC, 4 CD) patients, and after the first year in 9 (6 UC, 3 CD) patients. CDAI decreased transiently at the end of the sixth month, but no significant changes were observed in the CDAI or the CAI values at the end of the year. Leukocyte counts (P = 0.01), CRP (P = 0.02), and serum iron (P = 0.05) values indicated decreased inflammatory reactions, especially in the UC patients at the end of the year, making the possibility to taper oral steroid doses. CONCLUSION: About one-third of the previously AZA- intolerant patients showed adverse effects on taking 6MP. In our series, 20 patients tolerated 6MP, but it was ineffective in 8 CD cases, and valuable mainly in ulcerative colitis patients. | Ferenc Nagy Tamás Molnár Zoltán Szepes Klaudia Farkas Tibor Nyári János Lonovics | 2008 | World Journal of Gastroenterology2008，14，27： | 2 |
| 11 | Relationship between diabetes mellitus and cataract in Hungary显示文摘AIM:To examine the coexistence of diabetes mellitus(DM)and cataract in Hungary.The effects of DM on the cataract surgical results were also in the focus of analysis.METHODS:Statistical data analysis of the results of the Rapid Assessment of Avoidable Blindness with Diabetic Retinopathy(RAAB+DR)module conducted in Hungary in 2015.This cross-sectional,population-based,national survey included 3523 people aged 50 years and over.Participants of the survey were examined on-site.Visual acuity,main cause for visual impairment(using direct and indirect ophthalmoscopes),in case of best corrected visual acuity(BCVA)≤0.5 and blood glucose level(random test with glucometer)were examined.RESULTS:The prevalence of cataract was 23.4%,and DM was 20.0%.The occurrence of cataract steadily increased with age.Among the examined participants with DM,the prevalence of cataract was significantly(P=0.012)higher(+35%)than that in non-diabetic subjects(29.5%vs 21.8%).Following aging(OR=15.2%,P<0.001),DM proved to be the most independent influencing risk factor(OR=49.9%,P<0.001).The presence of DM was neither an influencing factor for complications of cataract surgery,nor for postoperative visual acuity.CONCLUSION:DM appears to be one of the main risk factors for developing cataract.Other risk factors,such as age,sex and environment also play an influencing role.Diabetes does not seem to affect the occurrence of cataract surgical complications. | Anita Pék Dorottya Szabó Gábor LászlóSándor Gábor Tóth András Papp Zoltán Zsolt Nagy Hans Limburg János Németh | 2020 | International Journal of Ophthalmology(English edition)2020，13，5： | 2 |
