| 1 | Serum and urine metabolomic fingerprinting in diagnostics of inflammatory bowel diseases显示文摘AIM:To evaluate the utility of serum and urine metabolomic analysis in diagnosing and monitoring of inflammatory bowel diseases(IBD).METHODS:Serum and urine samples were collected from 24 patients with ulcerative colitis(UC),19 patients with the Crohn’s disease(CD)and 17 healthy controls.The activity of UC was assessed with the Simple Clinical Colitis Activity Index,while the activity of CD was determined using the Harvey-Bradshaw Index.The analysis of serum and urine samples was performed using proton nuclear magnetic resonance(NMR)spectroscopy.All spectra were exported to Matlab for preprocessing which resulted in two data matrixes for serum and urine.Prior to the chemometric analysis,both data sets were unit variance scaled.The differences in metabolite fingerprints were assessed using partial least-squaresdiscriminant analysis(PLS-DA).Receiver operating characteristic curves and area under curves were used to evaluate the quality and prediction performance of the obtained PLS-DA models.Metabolites responsible for separation in models were tested using STATISTICA10 with the Mann-Whitney-Wilcoxon test and the Student’s t test(α=0.05).RESULTS:The comparison between the group of patients with active IBD and the group with IBD in remission provided good PLS-DA models(P value 0.002for serum and 0.003 for urine).The metabolites that allowed to distinguish these groups were:N-acetylated compounds and phenylalanine(up-regulated in serum),low-density lipoproteins and very low-density lipoproteins(decreased in serum)as well as glycine(increased in urine)and acetoacetate(decreased in urine).The significant differences in metabolomic profiles were also found between the group of patients with active IBD and healthy control subjects providing the PLS-DA models with a very good separation(P value<0.001 for serum and 0.003 for urine).The metabolites that were found to be the strongest biomarkers included in this case:leucine,isoleucine,3-hydroxybutyric acid,N-acetylated compounds,acetoacetate,glycine,phenylalanine and lactate(increased in serum),creatine,dimethyl sulfone,histidine,choline and its derivatives(decreased in serum),as well as citrate,hippurate,trigonelline,taurine,succinate and 2-hydroxyisobutyrate(decreased in urine).No clear separation in PLS-DA models was found between CD and UC patients based on the analysis of serum and urine samples,although one metabolite(formate)in univariate statistical analysis was significantly lower in serum of patients with active CD,and two metabolites(alanine and N-acetylated compounds)were significantly higher in serum of patients with CD when comparing jointly patients in the remission and active phase of the diseases.Contrary to the results obtained from the serum samples,the analysis of urine samples allowed to distinguish patients with IBD in remission from healthy control subjects.The metabolites of importance included in this case up-regulated acetoacetate and down-regulated citrate,hippurate,taurine,succinate,glycine,alanine and formate.CONCLUSION:NMR-based metabolomic fingerprinting of serum and urine has the potential to be a useful tool in distinguishing patients with active IBD from those in remission. | Tomasz Dawiskiba Stanislaw Deja Agata Mulak Adam Zabek Ewa Jawień Dorota Pawelka Miroslaw Banasik Agnieszka Mastalerz-Migas Waldemar Balcerzak Krzysztof Kaliszewski Jan Skóra Piotr Bar Krzysztof Korta Kornel Pormańczuk Przemyslaw Szyber Adam Litarski Piotr Mlynarz | 2014 | World Journal of Gastroenterology2014，20，1： | 15 |
| 2 | Epithelioid hemangioendothelioma of the liver as a rare indication for liver transplantation显示文摘AIM: To investigate the indications and outcomes of liver transplantation for hepatic epithelioid hemangioendothelioma(HEHE). METHODS: Between 1989 and August 2013, in the Department of General, Transplant, and Liver Surgery, Medical University of Warsaw, 1306 orthotopic liver transplantations(OLTx) were performed, including 72 retransplantations. Unresectable HEHE was an indication for OLTx in 10 patients(0.8% of primary OLTx), the mean age of the patients was 40.5 ± 13.3 years(range 23-65 years), and the male-to-female ratio was 2:8. Kaplan-Meier survival analysis in HEHE, hepatocellular carcinoma(HCC), and other OLTx recipients groups was performed. The differences in mortality were compared using the χ2 test. A P-value < 0.05 indicated statistical significance.RESULTS: No concomitant liver disease was found in any patient. There was no neoadjuvant chemotherapy or radiotherapy. Liver function test results were normal in most of the patients. The levels of alpha-fetoprotein, carcinoembryonic antigen, and carbohydrate antigen 19-9 were normal. In immunohistochemical staining, the neoplastic cells were positive for factor Ⅷ-related antigen, CD31, and CD34, which are endothelial cell markers, and negative for cytokeratin 19, cytokeratin 7, and HepPar-1. Nine patients were alive without tumor recurrence. One patient died 2 mo after OLTx due to septic complications. No morbidity was observed. Maximum follow-up was 11.4 years, with a minimum of 1 mo. The cumulative survival rate at the end of followup in HEHE patients was 87.5% compared with 54.3% in the HCC group and 76.3% in the other OLTx recipients group(χ2 test = 1.784, df = 2, P = 0.409).CONCLUSION: Unresectable HEHE, without extrahepatic metastases is an excellent indication for liver transplantation. Long-term survival is very good and much better than in HCC patients and the entire group of OLTx patients. | Piotr Remiszewski Ewa Szczerba Piotr Kalinowski Beata Gierej Krzysztof Dudek Mariusz Grodzicki Marcin Kotulski Rafa Paluszkiewicz Waldemar Patkowski Krzysztof Zieniewicz Marek Krawczyk | 2014 | World Journal of Gastroenterology2014，20，32： | 10 |
| 3 | Monocyte-to-lymphocyte ratio as a prognostic factor in peripheral whole blood samples of colorectal cancer patients显示文摘BACKGROUND Colorectal cancer is the third most common malignancy worldwide.Therefore,it is critically important to identify new useful markers that can be easily obtained in routine practice.Inflammation is a crucial issue in the pathogenesis and development of cancer.AIM To evaluate the prognostic value of absolute monocyte count,monocyte to lymphocyte ratio(MLR),the combination of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio(NLR-PLR),and combined platelet and neutrophilto-lymphocyte ratio(PLT-NLR)in peripheral blood samples of patients with colorectal cancer undergoing surgery.METHODS We conducted a retrospective study of 160 patients with colorectal cancer who underwent surgery,and 42 healthy controls.The status of absolute monocyte count,MLR,NLR-PLR and PLT-NLR was calculated on the basis of blood samples obtained before and after surgery.Haematologic factors were examined in correlation with the type of tumour growth,tumour size,histological type,percentage of mucinous component,grade of malignancy,Tumour-Node-Metastasis stage,venous,lymphatic and perineural invasion of cancer cells,status of lymph node invasion and the presence of cancer cell deposits.The Kaplan-Meier method and the long-rank test were used to compare survival curves.To determine independent prognostic factors,univariate and multivariate Cox proportional hazards regression models were applied.RESULTS The PLT-NLR status was correlated with tumour size and the presence of perineural invasion(P=0.015;P=-0.174,P=0.037).Moreover,high NLR-PLR and PLR-NLR ratios in the blood samples obtained after surgery were positively associated with histological type of cancer and percentage of the mucinous component(NLR-PLR:P=0.002;P=0.009;PLR-NLR status:P=0.002;P=0.007).The analysis of 5-year disease-free survival showed that the MLR of whole blood obtained after surgery[HR=2.903,95%CI:(1.368-6.158),P=0.005]and the status of lymph node metastasis[HR=0.813,95%CI:(0.653-1.013),P=0.050]were independent prognostic factors in colorectal cancer patients.CONCLUSION The postoperative MLR in whole blood samples can be used as an independent prognostic factor in patients diagnosed with colorectal cancer. | Katarzyna Jakubowska Mariusz Koda Małgorzata Grudzinska Luiza Kanczuga-Koda Waldemar Famulski | 2020 | World Journal of Gastroenterology2020，26，31： | 8 |
| 4 | Impact of IL28B and OAS gene family polymorphisms on interferon treatment response in Caucasian children chronically infected with hepatitis B virus显示文摘AIM To investigate the impact of IL28 B and OAS gene polymorphisms on interferon treatment responses in children with chronic hepatitis B.METHODS We enrolled 52 children(between the ages of 4 and 18) with hepatitis B e antigen-negative chronic hepatitis B(CHB), who were treated with pegylated interferon alfa for 48 wk. Single nucleotide polymorphisms in the OAS1(rs1131476), OAS2(rs1293747),OAS3(rs2072136), OASL(rs10849829) and IL28B(rs12979860, rs12980275 and rs8099917) genes were studied to examine their associations with responses to IFN treatment in paediatric patients. We adopted two criteria for the therapeutic response, achieving an hepatitis B virus(HBV) DNA level < 2000 IU/m L and normalization of ALT activity(< 40 IU/L). To perform the analyses, we compared the patients in terms of achieving a partial response(PR) and a complete response(CR) upon measurement at the 24-wk posttreatment follow-up. RESULTS The PR and CR rates were 80.8% and 42.3%, respectively. Factors such as age, gender and liver histology had no impact on the type of response(partial or complete). A statistically significant relationship between higher baseline HBV DNA and ALT activity levels and lower rates of PR and CR was shown(P < 0.05). The allele association analysis revealed that only the IL-28 B rs12979860(C vs T) and IL28 B rs12980275(A vs G) markers significantly affected the achievement of PR(P = 0.021, OR = 3.3, 95%CI: 1.2-9.2 and P = 0.014, OR = 3.7, 95%CI: 1.3-10.1, respectively). However, in the genotype analysis, only IL-28 B rs12980275 was significantly associated with PR(AA vs AG-GG, P = 0.014, OR = 10.9, 95%CI: 1.3-93.9). The association analysis for CR showed that the TT genotype of IL28 B rs12979860 was present only in the no-CR group(P = 0.033) and the AA genotype of OASL rs10849829 was significantly more frequent in the noCR group(P = 0.044, OR = 0.26, 95%CI: 0.07-0.88). The haplotype analysis revealed significant associations between PR and CR and OAS haplotype(P = 0.0002 and P = 0.001, respectively), but no association with IL28 B haplotype was observed.CONCLUSION IL28 B and OAS polymorphisms are associated with different clinical outcomes in CHB children treated with interferon. | Krzysztof Domagalski Malgorzata Pawlowska Agnieszka Zalesna Malgorzata Pilarczyk Pawel Rajewski Waldemar Halota Andrzej Tretyn | 2016 | World Journal of Gastroenterology2016，22，41： | 7 |

| 6 | Isolated right posterior bile duct injury following cholecystectomy:Report of two cases显示文摘Anatomic variations of the right biliary system are one of the most common risk factors for sectoral bile duct injury(BDI)during cholecystectomy.Isolated right posterior BDI may in particular be a challenge for both diagnosis and management.Herein we describe two cases of isolated right posterior sectoral BDI that took place during laparoscopic cholecystectomy.Despite effective external biliary drainage from the liver hilum in both cases,there was a persistent biliary leak observed which was not visible on endoscopic retrogradecholangiogram.Careful evaluation of images from both endoscopic and magnetic resonance cholangiograms revealed the diagnosis of an isolated right posterior sectoral BDI.These were treated with a delayed bisegmental(segments 6 and 7)liver resection and a Roux-en-Y hepaticojejunostomy respectively with good outcomes at 24 and 4 mo of follow-up.This paper discusses strategies for prevention of such injuries along with the diagnostic and therapeutic challenges it offers. | Maciej Wojcicki Waldemar Patkowski Tomasz Chmurowicz Andrzej Bialek Anna Wiechowska-Kozlowska Rafal Stankiewicz Piotr Milkiewicz Marek Krawczyk | 2013 | World Journal of Gastroenterology2013，19，36： | 5 |

| 10 | What's new in hepatitis C virus infections in children?显示文摘The number of hepatitis C virus(HCV) infection cases is relatively low in children. This low number may be connected with the lack of screening tests and the asymptomatic course of infection. Currently,mother-toinfant transmission is the most common cause of HCV infection amongst children in developed countries. It is important to introduce routine screening tests for HCV in pregnant women. The risk of vertical transmission of HCV is estimated at approximately 5%(3%-10%). Currently,we do not have HCV transmission prevention methods. Some factors could potentially be eliminated by elective caesarean section. Currently,the method of prevention of perinatal HCV infection is the early identification and effective treatment of infections in young women in the preconception period. We describe genetic tests(IL-28 B single nucleotide polymorphisms) to identify children with an increased chance of spontaneous clearance or sustained virologic response achievement and vitamin D level as a potential predictor of treatment response in children. It is also important to develop non-invasive tests that can predict liver fibrosis. The existence of differences in the mechanisms leading to liver injury between children and adults creates new perspectives of action to reduce liver disease progression in children in the early years of life. | Malgorzata Pawlowska Krzysztof Domagalski Anna Pniewska Beata Smok Waldemar Halota Andrzej Tretyn | 2015 | World Journal of Gastroenterology2015，21，38： | 3 |

| 12 | 急性心肌梗死阿昔单抗、瑞替普酶、支架联合研究(CARESS-in-AMI)中的即刻恤管成形术与常规治疗联合挽救性血管成形术的比较:一项前瞻性、开放、多中心随机试验显示文摘背景当90min内不能进行直接经皮冠状动脉介入术(PCI)时,溶栓就仍是ST段抬高型心肌梗死(STEMI)的治疗选择。然而,溶栓治疗之后患者的最佳后续处理仍不确定。为了评估最佳处理方案,作者把在非介入医院用溶栓和阿昔单抗治疗的STEMI患者随机分为即刻进行PCI与常规药物治疗联合挽救性血管成形术两组。
方法给予法国、意大利和波兰等国家的600例年龄≤75岁、有≥1项高危特征(广泛性ST段抬高、新发左柬支传导阻滞、既往有心肌梗死、Killip分级≥2级或左室射血分数≤35%)的住院患者半量瑞替普酶、阿昔单抗、肝素和阿司匹林治疗,并随机分配为转诊至最近的介入中心进行即刻PCI或仅在持续ST段抬高、临床征象加重时转诊。主要结局为30d时死亡、再梗死或顽固性心肌缺血的复合指标,采用意向治疗分析。研究在Clinical Trials.gov的注册编号为00220571。
结果分配至即刻PCI组的299例患者中,289例(97.0%)进行了血管造影,255例(85.6%)进行了PCI。在常规治疗/挽救性PCI组中有91例(30.3%)患者进行了挽救性PCI。即刻PCI组出现主要结局指标的患者为13例(4.4%),而常规治疗辟乞救性PCI组为32例(10.7%)(HR0-40,95%C10.21~0.76;对数秩检验P=0.004)。即刻PCI组严重出血患者为10例,而常规治疗/挽救性PCI组为7例(3.4%vs2.3%,P=0.47)。即刻PCI组卒中患者为2例.而常规治疗/挽救性PCI组为4例(0.7%vs 1.3%.P=0.50)。
结论 在非介入中心,采用半量瑞替普酶和阿昔单抗治疗的高危STEMI患者即刻转诊进行PCI可改善结局。 | Carlo Di Maria Dariusz Duded Federico Piscione Waldemar Mielecki Stefano Savonitto Ernesto Murena Konstantinos Dimopoulos 郭占宏(译) | 2008 | 世界临床医学2008，2，5： | 3 |
| 13 | Reduced anoctamin 7(ANO7) expression is a strong and independent predictor of poor prognosis in prostate cancer显示文摘Objective:Anoctamin 7(ANO7)is a calcium2+-dependent chloride ion channel protein.Its expression is restricted to prostate epithelial cells.The exact function is unknown.This study aimed to analyze ANO7 expression and its clinical significance in prostate cancer(PCa).Methods:ANO7 expression was assessed by immunohistochemistry in 17,747 clinical PCa specimens.Results:ANO7 was strongly expressed in normal prostate glandular cells but often less abundant in cancer cells.ANO7 staining was interpretable in 13,594 cancer tissues and considered strong in 34.4%,moderate in 48.7%,weak in 9.3%,and negative in 7.6%.Reduced staining was tightly linked to adverse tumor features[high classical and quantitative Gleason grade,lymph node metastasis,advanced tumor stage,high Ki67 labeling index,positive surgical margin,and early biochemical recurrence(P<0.0001 each)].The univariate Cox hazard ratio for prostate-specific antigen(PSA)recurrence after prostatectomy in patients with negative vs.strong ANO7 expression was 2.98(95%confidence interval 2.61–3.38).The prognostic impact was independent of established pre-or postoperatively available parameters(P<0.0001).Analysis of annotated molecular data showed that low ANO7 expression was linked to TMPRSS2:ERG fusions(P<0.0001),elevated androgen receptor expression(P<0.0001),as well as presence of 9 of 11 chromosomal deletions(P<0.05 each).A particularly strong association of low ANO7 expression with phosphatase and tensin homolog(PTEN)deletion may indicate a functional relationship with the PTEN/AKT pathway.Conclusions:These data identify reduced ANO7 protein expression as a strong and independent predictor of poor prognosis in PCa.ANO7 measurement,either alone or in combination,might provide clinically useful prognostic information in PCa. | Andreas Marx Lena Koopmann Doris Hoflmayer Franziska Büscheck Claudia Hube-Magg Stefan Steurer Till Eichenauer Till S.Clauditz Waldemar Wilczak Ronald Simon Guido Sauter Jakob R.Izbicki Hartwig Huland Hans Heinzer Markus Graefen Alexander Haese Thorsten Schlomm Christian Bernreuther Patrick Lebok Sarah Bonk | 2021 | Cancer Biology & Medicine2021，18，1： | 3 |
| 14 | Methane - the Promising Career of a Humble Molecule显示文摘Methane, CH4, here represents natural gas (NG) of which it is the main constituent. Routes of chemical utilisation of NG - as opposed to energy usage - are discussed. A main step is the conversion of NG to synthesis gas, a mixture of CO and H2.

| 17 | Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis. | Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio | 2019 | Asian Journal of Andrology2019，21，2： | 2 |

| 19 | Fulminant liver failure following a marathon: Five case reports and review of literature显示文摘BACKGROUND The growing popularity of marathon and half-marathon runs has led to an increased number of patients presenting with exertion-induced heat stroke. Mild hepatic involvement is often observed in these patients;however, fulminant liver failure may occur in approximately 5% of all cases. Liver transplantation is a potentially curative approach for exertion-induced liver failure, although there is a lack of consensus regarding the criteria and optimal timing of this intervention. CASE SUMMARY This paper describes 5 patients (4 men and 1 woman) who were referred to the department where this study was performed with the diagnosis of exertioninduced acute liver failure. Three patients underwent liver transplantation, 1 recovered spontaneously, and 1 patient died on day 11 following the exertion. CONCLUSION Exertion-induced heat stroke may present as fulminant liver failure. These patients may recover with conservative treatment, may require liver transplantation, or may die. No definitive criteria are available to determine patient suitability for a conservative vs surgical approach. | Wojciech Figiel Marcin Morawski Michal Grat Oskar Kornasiewicz Grzegorz Niewiński Joanna Raszeja-Wyszomirska Maciej Krasnodebski Arkadiusz Kowalczyk Waclaw Holówko Waldemar Patkowski Krzysztof Zieniewicz | 2019 | World Journal of Clinical Cases2019，7，12： | 2 |
