3Is there a role for surgery in stage ⅢA-N2 non-small cell lung cancer?显示文摘The role of surgery in stage ⅢA-N2 non-small cell lung cancer(NSCLC) remains controversial.Most important prognostic factors are mediastinal downstaging and complete surgical resection.Different restaging techniques exist to evaluate response after induction therapy and these are subdivided into non-invasive,invasive and alternative or minimally invasive techniques.In contrast to imaging or functional studies,remediastinoscopy provides pathological evidence of response after induction therapy.Although techn...Paul E.VAN SCHIL Michèle DE WAELE Jeroen M.HENDRIKS Patrick R.LAUWERS 2008中国肺癌杂志2008,11,5:14
4Reversibility of minimal hepatic encephalopathy following liver transplantation in Egyptian cirrhotic patients显示文摘AIM To evaluate the reversibility of minimal hepatic encephalopathy(MHE) following liver transplantation(LT) in Egyptian cirrhotic patients. METHODS This prospective study included twenty patients with biopsy-proven liver cirrhosis listed for LT and twenty ageand sex-matched healthy control subjects. All underwent neuro-psychiatric examination, laboratory investigations, radiological studies and psychometric tests including trail making test A(TMT A), TMT B, digit symbol test and serial dotting test. The psychometric hepatic encephalopathy score(PHES) was calculated for patients to diagnose MHE. Psychometric tests were repeated six months following LT in the cirrhotic patient group. RESULTS Before LT, psychometric tests showed highly significant deficits in cirrhotic patients in comparison to controls(P < 0.001). There was a statistically significant improvement in test values in the patient group after LT; however, their values were still significantly worse than those of the controls(P < 0.001). The PHES detected MHE in 16 patients(80%) before LT with a median value of -7 ± 3.5. The median PHES value was significantly improved following LT, reaching-4.5 ± 5(P < 0.001), and the number of patients with MHE decreased to 11(55%). The pre-transplant model for end-stage liver disease(MELD) score ≥ 15 was significantly related to the presence of post-transplant MHE(P = 0.005). More patients in whom reversal of MHE was observed had a pre-transplant MELD score < 15.CONCLUSION Reversal of MHE in cirrhotic patients could be achieved by LT, especially in those with a MELD score < 15.Mahmoud A Osman Moataz M Sayed Khaled A Mansour Shereen A Saleh Wesam A Ibrahim Sara M Abdelhakam Mohamed Bahaa Wael A Yousry Hosam S Elbaz Reginia N Mikhail Azza M Hassan Ehab H Elsayed Dalia A Mahmoud 2016World Journal of Hepatology2016,8,30:11

6Prognostic factors in patients with advanced cholangiocarcinoma: Role of surgery, chemotherapy and body mass index显示文摘AIM: To study the factors that may affect survival of cholangiocarcinoma in Lebanon. METHODS: A retrospective review of the medical records of 55 patients diagnosed with cholangio- carcinoma at the American University of Beirut between 1990 and 2005 was conducted. Univariate and multivariate analyses were performed to determine the impact of surgery, chemotherapy, body mass index, bilirubin level and other factors on survival. RESULTS: The median survival of all patients was 8.57 mo (0.03-105.2). Univariate analysis showed that low bilirubin level (< 10 mg/dL), radical surgery and chemotherapy administration were significantly associated with better survival (P = 0.012, 0.038 and 0.038, respectively). In subgroup analysis on patients who had no surgery, chemotherapy administration prolonged median survival significantly (17.0 mo vs 3.5 mo, P = 0.001). Multivariate analysis identifiedonly low bilirubin level < 10 mg/dL and chemotherapy administration as independent predictors associated with better survival (P < 0.05). CONCLUSION: Our data show that palliative and postoperative chemotherapy as well as a bilirubin level < 10 mg/dL are independent predictors of a significant increase in survival in patients with cholangiocarcinoma.Mirna H Farhat Ali I Shamseddine Ayman N Tawil Ghina Berjawi Charif Sidani Wael Shamseddeen Kassem A Barada 2008World Journal of Gastroenterology2008,14,20:9

8Role of AXL in invasion and drug resistance of colon and breast cancer cells and its association with p53 alterations显示文摘AIM To characterize AXL receptor tyrosine kinase(AXL)expression in relationship to tumor protein P53(TP53gene,p53 protein)and its role in tumor invasion and response to therapy.METHODS We used 14 cell lines,including 3 isogenic pairs carrying mutant/knockout p53,to gain insight into the relationship between AXL and TP53.These included HCT116,HCT116.p53 mutant,RKO,and RKO.p53-/-lines(all from colon cancers)as well as breast cancer cell lines MCF7 and 1001(MCF7-p53 mutant clone).He La cell line was used as a positive control for epithelial to mesenchymal transition(EMT).AXL expression was determined by Western blotting using rabbit monoclonal antibody clone C89E7.AXL si RNA silencing was performed and followed by collagen invasion assay.Cell viability analysis using the sulforhodamine B assay and the invasion assay were performed after exposure to chemotherapeutic agents(doxorubicin for breast cancer cells;5FU or irinotecan for colon cancer cells).RESULTS We showed that the introduction of p53 mutations or knockout increased expression levels of AXL in isogenic cells compared to the matching p53 wild-type parental cells.Overall,we found a trend for correlation between the potential EMT candidate AXL,p53 alterations,and EMT markers in colorectal and breast cancers.The expression of AXL in RKO cells,a rare colon cancer cell line with inactive Wnt signaling,suggests that the AXL oncogene might provide an alternative genetic pathway for colorectal carcinogenesis in the absence of Wnt signaling activation and TP53 mutation.AXL silencing in the TP53 mutant isogenic cell lines 1001,HCT116.p53 mutant and RKO.P53-/-was>95%efficient and the silenced cells were less invasive compared to the parental TP53 wild-type cells.AXL silencing showed a subtle trend to restore colon cancer cell sensitivity to5FU or irinotecan.Importantly,AXL expressing cells developed more invasive potential after exposure to chemotherapy compared to the AXL-silenced cells.CONCLUSION AXL is influenced by p53 status and could cause the emergence of aggressive clones after exposure to chemotherapy.These findings could have applications in cancer management.Wael M Abdel-Rahman Noura A Al-khayyal Vidhya A Nair S R Aravind Maha Saber-Ayad 2017World Journal of Gastroenterology2017,23,19:7
9Molecular detection of monocyte chemotactic protein-1 polymorphism in spontaneous bacterial peritonitis patients显示文摘AIM: To investigate the association of the functional monocyte chemotactic protein-1(MCP-1) promoter polymorphism(A-2518G) with spontaneous bacterial peritonitis(SBP).METHODS: Fifty patients with post-hepatitis C liver cirrhosis and ascites were categorized into two groups; group Ⅰ included 25 patients with SBP and group Ⅱ included 25 patients free from SBP. In addition, a group of 20 healthy volunteers were included. We assessed the MCP-1 gene polymorphism and gene expression as well as interleukin(IL)-10 levels in both blood and ascitic fluid. RESULTS: A significant MCP-1 gene polymorphism was detected in groups Ⅰ and Ⅱ(P = 0.001 and 0.02 respectively). Group Ⅰ was associated with a significantly higher frequency of AG genotype [control 8(40%) vs SBP 19(76.0%), P < 0.001], and group Ⅱ was associated with a significantly higher frequency of GG genotype when compared to healthy volunteers [control 1(5%) vs cirrhotic 16(64%), P < 0.001]. Accordingly, the frequency of G allele was significantly higher in both groups(Ⅰ and Ⅱ) [control 10(25%) vs SBP 27(54%), P < 0.001 and vs cirrhotic 37(74.0%), P < 0.001, respectively]. The total blood and ascetic fluid levels of IL-10 and MCP-1 gene expression were significantly higher in group Ⅰ than in group Ⅱ. Group Ⅰ showed significant reductions in the levels of MCP-1 gene expression and IL-10 in the whole blood and ascetic fluid after therapy. CONCLUSION: MCP-1 GG genotype and G allele may predispose HCV infected patients to a more progressive disease course, while AG genotype may increase the susceptibility to SBP. Patients carrying these genotypes should be under supervision to prevent or restrict further complications.Maysa Kamal Salama Dina Sabry Mohamed AS Al-Ghussein Rasha Ahmed Sayed AbdAllah Fatma Mohamed Taha Wael Fathy Miriam Safwat Wadie Mona Nabih Amr Abul-Fotouh Tarneem Darwish 2014World Journal of Gastroenterology2014,20,33:7

11Current concepts in total femoral replacement显示文摘Total femoral replacement(TFR) is a salvage arthroplasty procedure used as an alternative to lower limb amputation. Since its initial description in the mid-20^(th) century, this procedure has been used in a variety of oncologic and non-oncologic indications. The most compelling advantage of TFR is the achievement of immediate fixation which permits early mobilization. It is anticipated that TFR will be increasingly performed as the rate of revision arthroplasty rises worldwide. The existing literature is mainly composed of a rather heterogeneous mix of retrospective case series and a wide assortment of case reports. Numerous TFR prostheses are currently available and the surgeon must understand the unique implications of each implant design. Long-term functional outcomes are dependent on adherence to proper technique and an appropriate physical therapy program for postoperative rehabilitation. Revision TFR is mainly performed for periprosthetic infection and the severe femoral bone loss associated with aseptic revisions. Depending on the likelihood of attaining infection clearance, it may sometimes be advisable to proceed directly to hip disarticulation without attempting salvage of the TFR. Other reported complications of TFR include hip joint instability, limb length discrepancy, device failure, component loosening, patellar maltracking and delayed wound healing. Further research is needed to better characterize the long-term functional outcomes and complications associated with this complex procedure.Deepak Ramanathan Marcelo BP Siqueira Alison K Klika Carlos A Higuera Wael K Barsoum Michael J Joyce 2015World Journal of Orthopedics2015,6,11:6
12Role of negative pressure wound therapy in total hip and knee arthroplasty显示文摘Negative-pressure wound therapy(NPWT) has been a successful modality of wound management which is in widespread use in several surgical fields. The main mechanisms of action thought to play a role in enhancing wound healing and preventing surgical site infection are macrodeformation and microdeformation of the wound bed, fluid removal, and stabilization of the wound environment. Due to the devastating consequences of infection in the setting of joint arthroplasty, there has been some interest in the use of NPWT following total hip arthroplasty and total knee arthroplasty. However, there is still a scarcity of data reporting on the use of NPWT within this field and most studies are limited by small sample sizes, high variability of clinical settings and end-points. There is little evidence to support the use of NPWT as an adjunctive treatment for surgical wound drainage, and for this reason surgical intervention should not be delayed when indicated. The prophylactic use of NPWT after arthroplasty in patients that are at high risk for postoperative wound drainage appears to have the strongest clinical evidence. Several clinical trialsincluding single-use NPWT devices for this purpose are currently in progress and this may soon be incorporated in clinical guidelines as a mean to prevent periprosthetic joint infections.Marcelo BP Siqueira Deepak Ramanathan Alison K Klika Carlos A Higuera Wael K Barsoum 2016World Journal of Orthopedics2016,7,1:5
13Differential roles of EPS8 in carcinogenesis:Loss of protein expression in a subset of colorectal carcinoma and adenoma显示文摘AIM:To analyze the epidermal growth factor receptor pathway substrate 8(EPS8) expression status and role in colorectal carcinogenesis given that EPS8 has a conserved actin barbed-end capping function that is required for proper maturation in intestinal cells.METHODS:We studied 8 colon cancer cell lines and 58 colorectal tumors(19 adenomas and 39 carcinomas).We performed expression microarray analysis of colon cancer cell lines followed by loss of heterozygosity(LOH)analysis and immunohistochemistry for EPS8 expression in colon tumors.Subsequently,we performed mutation analysis by direct sequencing and methylation analysis by bisulfite sequencing and methylation-specific polymerase chain reaction assays.RESULTS:Expression microarray analysis of colon cancer cell lines showed overexpression of EPS8 transcript in all lines but RKO.Genome wide loss of heterozygosity(LOH) analysis of colon tumors,showed considerable LOH at the EPS8 gene locus.Immunohistochemically,EPS8 was constitutively expressed in normal colonic mucosa with a dot-like supranuclear localization with accentuation at the luminal surface supporting its proposed role in epithelial maturation.Nineteen colon tumors(4 adenoma,15 carcinoma) out of 51(37%) showed strikingly tumor specific EPS8 protein loss.Of the remaining tumors,5/51(2 adenoma,and 3 carcinoma,10%) showed marked overexpression,while 27/51 tumors(53%) showed retained expression.Mutation analysis revealed a missense mutation(c.794C>T,p.R265C) in exon 8 in RKO.The EPS8 promoter was also methylated in RKO,but there was no significant methylation in other cell lines or carcinoma specimens.CONCLUSION:The loss of EPS8 expression in colorectal adenomas and carcinomas suggests that down regulation of this gene contributes to the development of a subset of colorectal cancers,a finding which could have applications in diagnosis and treatment.Wael M Abdel-Rahman Salla Ruosaari Sakari Knuutila Pivi Peltomki 2012World Journal of Gastroenterology2012,18,29:5
14p53 antibodies,metallothioneins,and oxidative stress markers in chronic ulcerative colitis with dysplasia显示文摘AIM:To investigate the role of p53 antibodies (p53Abs),metallothioneins (MTs) and oxidative stress markers in the early detection of dysplasia in chronic ulcerative colitis (UC).METHODS:The study included 30 UC patients,15 without dysplasia (group Ⅱ) and 15 with dysplasia (group Ⅲ),in addition to 15 healthy volunteers (group Ⅰ,control subjects).The enzyme-linked immunosorbent assay technique was used to measure serum p53Abs and MTs,while advanced oxidation protein products (AOPPs),and reduced glutathione (GSH) levels were measured by spectrophotometric method in all subjects.RESULTS:In group Ⅱ and group Ⅲ compared to group Ⅰ,there were significant increases in serum levels of AOPPs (145.94 ± 29.86 μmol/L and 192.21 ± 46.71 μmol/L vs 128.95 ± 3.06 μmol/L,P < 0.002 and P <0.001,respectively),MTs (8.18 ± 0.35 μg/mL and 9.20 ± 0.58 μg/mL vs 6.12 ± 0.25 μg/mL,P < 0.05 and P < 0.05,respectively),and p53Abs (20.19 ± 3.20 U/mL and 34.66 ± 1.34 U/mL vs 9.42 ± 1.64 U/mL,P < 0.001 and P < 0.001,respectively).There were significantly higher levels of AOPPs (P < 0.05) and p53Abs (P < 0.001) in UC patients with dysplasia compared to those without dysplasia,while MTs showed no significant difference between the 2 groups (P > 0.096).In contrast,GSH levels showed a significant decrease in both patients' groups (1.87 ± 0.02 μmol/mL and 1.37 ± 0.09 μmol/mL vs 2.49 ± 0.10 μmol/mL,P < 0.05 and P < 0.05 in groups Ⅱ and Ⅲ,respectively) compared with group Ⅰ,and the levels were significantly lower in group Ⅲ than group Ⅱ (P < 0.05).There was a positive correlation between AOPPs and both MTs (r=0.678,P < 0.001) and p53Abs (r=0.547,P < 0.001),and also between p53Abs and MTs (r=0.739,P < 0.001).There was a negative correlation between AOPPs and GSH (r =-0.385,P < 0.001),and also between GSH and both MTs (r=-0.662,P < 0.001) and p53Abs (r=-0.923,P < 0.001).CONCLUSION:Oxidative stress and oxidative cellular damage play an important role in the pathogenesis of chronic UC and the associated carcinogenetic process.p53Abs levels could help in early detection of dysplasia in these conditions.Hala E Hamouda Soha S Zakaria Saber A Ismail Mahmoud A Khedr Wael W Mayah 2011World Journal of Gastroenterology2011,17,19:5
15Association between low molecular polypeptide 7 single nucleotide polymorphism and response to therapy in hepatitis C virus infection显示文摘AIM: To investigate the relationship between low molecular polypeptide-7 (LMP-7) gene polymorphism and response to interferon (IFN) therapy in chronic hepatitis C virus (HCV) patients. METHODS: LMP-7 polymorphism at codon 49 with nucleotide substitution from A to C was amplified in 104 chronic HCV patients of genotype 4. The amplicons were digested with restriction endonuclease Bsm I and the produced restriction fragment length polymorphism was analyzed. Patients received IFN + regional blood volume therapy for 48 wk and the frequency of thissingle nucleotide polymorphism (SNP) was statistically correlated with treatment response. The exclusion criteria for these patients were stated by the national health program for treating viral hepatitis. Main exclusion criteria included co-infection with hepatitis B virus or schistosomiasis, thyroid dysfunction, uncontrolled diabetes mellitus, history of long term drug or alcohol intake and autoimmune hepatitis. Multivariate analyses were done to correlate LMP-7 SNP plus several factors such as age, gender, weight, serum alpha-fetoprotein (AFP) and alanine aminotransferase levels, liver activity, fibrosis score and viral load with response to therapy. RESULTS: The data presented in this study clearly demonstrated statistically significant differences between sustained virological response (SVR) (defined as the absence of HCV RNA levels in the patient's sera at least 6 mo after discontinuation of treatment) and non-response (NR) (where HCV RNA levels in the patient's sera never become undetectable for 6 mo during or after treatment). Variables were described as odds ratio with 95%CI. The data were considered significant if P values were ≤ 0.05; highly significant if P < 0.01 and very highly significant if P < 0.001. Current data showed that 91.7% of patients carrying LMP-7 C/C allele were associated with SVR, while the other two genotypes C/A and A/A were associated with NR patients, 83.3% and 64.3% respectively, showing that genotype CC was strongly associated with response to interferon (95%CI: 12.0719-134.6572, P = 0.0001). The majority of parameters recorded in SVR and NR patients included higher values of mean age (P = 0.004), alanine aminotransferase (P = 0.001), AFP (P = 0.001), body weight (P = 0.025), viral load (P = 0.025), higher fibrosis and histological activity index indices among NR vs SVR patients. Also, the multivariate statistical analysis of the different factors of fibro-sis score, liver activity grade, genotypes and alleles of LMP-7 gene polymorphism in responders and NRs of HCV patients in this study showed that HCV patients with A allele had a very highly significant association with the NRs, high fibrosis and higher liver activity, while the C allele had a very highly significant association with the responders, low fibrosis and lower liver activity (95%CI: 3.5800-13.2519, P = 0.0001).CONCLUSION: LMP-7 SNP is a candidate gene that should be considered when designing a mathematical model for predicting response to therapy and disease progression in HCV patients.Moataza H Omran Basma E Fotouh Samar S Youssef Noha E Ibrahim Wael Nabil EL-Sayed M Mahdy Wafaa G Shosha Mostafa K El-Awady 2013World Journal of Hepatology2013,5,3:4
16Endoscopic ultrasound in gastroenterology:From diagnosis to therapeutic implications显示文摘Since its advent in 1980,the scope of endoscopic ultrasound(EUS)has grown to include a wide range of indications,and it is now being incorporated as an integral part of everyday practice in the field of gastroenterology.Its use is extending from an adjuvant imaging aid to utilization as a therapeutic tool for various gastrointestinal disorders.EUS was first used to visualize remote organs,such as the pancreas and abdominal lymph nodes.When fine needle aspiration was introduced,the indications for EUS expanded to include tissue sampling for diagnostic purposes.At the same time,the needle can be used to convey a potential therapy to the internal organs,allowing access to remote sites.In this review,we aim to highlight the expanding spectrum of EUS indications and uses in the field of gastroenterology.Mohamed A Mekky Wael A Abbas 2014World Journal of Gastroenterology2014,20,24:4

18Comparative Analysis of Wavelet Transform for Time-Frequency Analysis and Transient Localization in Structural Health Monitoring显示文摘A critical problem facing data collection in structural health monitoring,for instance via sensor networks,is how to extract the main components and useful features for damage detection.A structural dynamic measurement is more often a complex time-varying process and therefore,is prone to dynamic changes in time-frequency contents.To extract the signal components and capture the useful features associated with damage from such nonstationary signals,a technique that combines the time and frequency analysis and shows the signal evolution in both time and frequency is required.Wavelet analyses have proven to be a viable and effective tool in this regard.Wavelet transform(WT)can analyze different signal components and then comparing the characteristics of each signal with a resolution matched to its scale.However,the challenge is the selection of a proper wavelet since various wavelets with varied properties that are to analyze the same data may result in different results.This article presents a study on how to carry out a comparative analysis based on analytic wavelet scalograms,using structural dynamic acceleration responses,to evaluate the effectiveness of various wavelets for damage detection in civil structures.The scalogram’s informative time-frequency regions are examined to analyze the variation of wavelet coefficients and show how the frequency content of a signal changes over time to detect transient events due to damage.Subsequently,damage-induced changes are tracked with time-frequency representations.Towards this aim,energy distribution and sharing information are investigated.The undamaged and damaged simulated comparative results of a structure reveal that the damaged structure were shifted from the undamaged structure.Also,the Bump wavelet shows the best results than the others.Ahmed Silik Mohammad Noori Wael A.Altabey Ramin Ghiasi Zhishen Wu 2021Structural Durability & Health Monitoring2021,15,1:4
19Barrett's esophagus:Prevalence and risk factors in patients with chronic GERD in Upper Egypt显示文摘AIM:To determine the prevalence and possible risk factors of Barrett's esophagus(BE) in patients with chronic gastroesophageal reflux disease(GERD) in El Minya and Assuit, Upper Egypt.METHODS:One thousand consecutive patients with chronic GERD symptoms were included in the study over 2 years.They were subjected to history taking including a questionnaire for GERD symptoms, clinical examination and upper digestive tract endoscopy.Endoscopic signs suggestive of columnar-lined esophagus(CLE) were defined as mucosal tongues or an upward shift of the squamocolumnar junction.BE was diagnosed by pathological examination when specialized intestinal metaplasia was detected histologically in suspected CLE.pH was monitored in 40 patients.RESULTS:BE was present in 7.3% of patients with chronic GERD symptoms, with a mean age of 48.3 ± 8.2 years, which was signif icantly higher than patients with GERD without BE(37.4 ± 13.6 years).Adenocarcinomawas detected in eight cases(0.8%), six of them in BE patients.There was no signiflcant difference between patients with BE and GERD regarding sex, smoking, alcohol consumption or symptoms of GERD.Patients with BE had significantly longer esophageal acid exposure time in the supine position, measured by pH monitoring.CONCLUSION:The prevalence of BE in patients with GERD who were referred for endoscopy was 7.3%.BE seems to be associated with older age and more in patients with nocturnal gastroesophageal reflux.Yasser M Fouad Madiha M Makhlouf Heba M Tawfik Hussein El Amin Wael Abdel Ghany Hisham R El-khayat 2009World Journal of Gastroenterology2009,15,28:4
20Enhancer variants reveal a conserved transcription factor network governed by PU.1 during osteoclast differentiation显示文摘Genome-wide association studies(GWASs) have been instrumental in understanding complex phenotypic traits. However, they have rarely been used to understand lineage-specific pathways and functions that contribute to the trait. In this study, by integrating lineage-specific enhancers from mesenchymal and myeloid compartments with bone mineral density loci, we were able to segregate osteoblast-and osteoclast(OC)-specific functions. Specifically, in OCs, a PU.1-dependent transcription factor(TF)network was revealed. Deletion of PU.1 in OCs in mice resulted in severe osteopetrosis. Functional genomic analysis indicated PU.1 and MITF orchestrated a TF network essential for OC differentiation. Several of these TFs were regulated by cooperative binding of PU.1 with BRD4 to form superenhancers. Further, PU.1 is essential for conformational changes in the superenhancer region of Nfatc1. In summary, our study demonstrates that combining GWASs with genome-wide binding studies and model organisms could decipher lineage-specific pathways contributing to complex disease states.Heather A.Carey Blake E.Hildreth III Jennifer A.Geisler Mara C.Nickel Jennifer Cabrera Sankha Ghosh Yue Jiang Jing Yan James Lee Sandeep Makam Nicholas A.Young Giancarlo R.Valiente Wael N.Jarjour Kun Huang Thomas J.Rosol Ramiro E.Toribio Julia F.Charles Michael C.Ostrowski Sudarshana M.Sharma 2018Bone Research2018,6,1:4
