| 1 | Circulating micro RNA, mi R-122 and mi R-221 signature in Egyptian patients with chronic hepatitis C related hepatocellular carcinoma显示文摘AIM: To explore the potential usefulness of serum miR-122 and miR-221 as non-invasive diagnostic markers of hepatitis C virus(HCV)-related hepatocellular carcinoma(HCC).METHODS: This prospective study was conducted on 90 adult patients of both sex with HCV-related chronic liver disease and chronic hepatitis C related HCC. In addition to the 10 healthy control individuals, patients were stratified into; interferon-na?ve chronic hepatitis C(CH)(n = 30), post-hepatitis C compensated cirrhosis(LC)(n = 30) and treatment-naive HCC(n = 30). All patients and controls underwent full clinical assessment and laboratory investigations in addition to the evaluation of the level of serum miR NA expression by RT-PCR.RESULTS: There was a significant fold change in serum mi RNA expression in the different patient groups when compared to normal controls; mi R-122 showed significant fold increasing in both CH and HCC and significant fold decrease in LC. On the other hand, mi R-221 showed significant fold elevation in both CH and LC groups and significant fold decrease in HCC group(P = 0.01). Comparing fold changes in miR NAs in HCC group vs non HCC group(CH and Cirrhosis), there was non-significant fold elevation in miR-122(P = 0.21) and significant fold decreasing in miR-221 in HCC vs non-HCC(P = 0.03). ROC curve analysis for miR-221 yielded 87% sensitivity and 40% specificity for the differentiation of HCC patients from non-HCC at a cutoff 1.82. CONCLUSION: Serum miR-221 has a strong potential to serve as one of the novel non-invasive biomarkers of HCC. | Hassan El-Garem Ayman Ammer Hany Shehab Olfat Shaker Mohammed Anwer Wafaa El-Akel Heba Omar | 2014 | World Journal of Hepatology2014，6，11： | 18 |
| 2 | Clinical correlates of common corneal neovascular diseases: a literature review显示文摘A large subset of corneal pathologies involves the formation of new vessels(neovascularization), leading to compromised visual acuity. This article aims to review the clinical causes and presentations of corneal neovascularization(CNV) by examining the mechanisms behind common CNV-related corneal pathologies, with a particular focus on herpes simplex stromal keratitis,contact lenses-induced keratitis and CNV secondary to keratoplasty. Moreover, we reviewed CNV in the context of different types of corneal transplantation and keratoprosthesis, and summarized the most relevant treatment available so far. | Nizar Saleh Abdelfattah Mohamed Amgad Amira A Zayed Hamdy Salem Ahmed E Elkhanany Heba Hussein Nawal Abd El-Baky | 2015 | International Journal of Ophthalmology(English edition)2015，8，1： | 10 |
| 3 | Pivotal role of long non-coding ribonucleic acid-X-inactive specific transcript in regulating immune checkpoint programmed death ligand 1 through a shared pathway between miR-194-5p and miR-155-5p in hepatocellular carcinoma显示文摘BACKGROUND Anti-programmed death therapy has thrust immunotherapy into the spotlight.However,such therapy has a modest response in hepatocellular carcinoma(HCC).Epigenetic immunomodulation is a suggestive combinatorial therapy with immune checkpoint blockade.Non-coding ribonucleic acid(ncRNA)driven regulation is a major mechanism of epigenetic modulation.Given the wide range of ncRNAs that co-opt in programmed cell-death protein 1(PD-1)/programmed death ligand 1(PD-L1)regulation,and based on the literature,we hypothesized that miR-155-5p,miR-194-5p and long non-coding RNAs(lncRNAs)X-inactive specific transcript(XIST)and MALAT-1 are involved in a regulatory upstream pathway for PD-1/PD-L1.Recently,nutraceutical therapeutics in cancers have received increasing attention.Thus,it is interesting to study the impact of oleuropein on the respective study key players.AIM To explore potential upstream regulatory ncRNAs for the immune checkpoint PD-1/PD-L1.METHODS Bioinformatics tools including microrna.org and lnCeDB software were adopted to detect targeting of miR-155-5p,miR-194-5p and lncRNAs XIST and MALAT-1 to PD-L1 mRNA,respectively.In addition,Diana tool was used to predict targeting of both aforementioned miRNAs to lncRNAs XIST and MALAT-1.HCC and normal tissue samples were collected for scanning of PD-L1,XIST and MALAT-1 expression.To study the interaction among miR-155-5p,miR-194-5p,lncRNAs XIST and MALAT-1,as well as PD-L1 mRNA,a series of transfections of the Huh-7 cell line was carried out.RESULTS Bioinformatics software predicted that miR-155-5p and miR-194-5p can target PDL1,MALAT-1 and XIST.MALAT-1 and XIST were predicted to target PD-L1 mRNA.PD-L1 and XIST were significantly upregulated in 23 HCC biopsies compared to healthy controls;however,MALAT-1 was barely detected.MiR-194 induced expression elevated the expression of PD-L1,XIST and MALAT-1.However,overexpression of miR-155-5p induced the upregulation of PD-L1 and XIST,while it had a negative impact on MALAT-1 expression.Knockdown of XIST did have an impact on PD-L1 expression;however,following knockdown of the negative regulator of X-inactive specific transcript(TSIX),PD-L1 expression was elevated,and abolished MALAT-1 activity.Upon co-transfection of miR-194-5p with siMALAT-1,PD-L1 expression was elevated.Co-transfection of miR-194-5p with siXIST did not have an impact on PD-L1 expression.Upon co-transfection of miR-194 with siTSIX,PD-L1 expression was upregulated.Interestingly,the same PD-L1 expression pattern was observed following miR-155-5p cotransfections.Oleuropein treatment of Huh-7 cells reduced the expression profile of PD-L1,XIST,and miR-155-5p,upregulated the expression of miR-194-5p and had no significant impact on the MALAT-1 expression profile.CONCLUSION This study reported a novel finding revealing that opposing acting miRNAs in HCC,have the same impact on PD-1/PD-L1 immune checkpoint by sharing a common signaling pathway. | Sara M Atwa Heba Handoussa Karim M Hosny Margarete Odenthal Hend M El Tayebi | 2020 | World Journal of Hepatology2020，12，12： | 9 |
| 4 | Diffusion-weighted magnetic resonance imaging and micro-RNA in the diagnosis of hepatic fibrosis in chronic hepatitis C virus显示文摘BACKGROUND Diffusion-weighted magnetic resonance imaging has shown promise in the detection and quantification of hepatic fibrosis. In addition, the liver has numerous endogenous micro-RNAs(miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis.AIM To assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.METHODS This prospective study included 208 patients and 82 age-and sex-matched controls who underwent diffusion-weighted magnetic resonance imaging of the abdomen, miR profiling, and liver biopsy. Pathological scoring was classified according to the METAVIR scoring system. The apparent diffusion coefficient (ADC) and miR were calculated and correlated with pathological scoring.RESULTS The ADC value decreased significantly with the progression of fibrosis, from controls(F0) to patients with early fibrosis(F1 and F2) to those with late fibrosis(F3 and F4)(median 1.92, 1.53, and 1.25 × 10^(-3) mm^2/s, respectively)(P = 0.001).The cut-off ADC value used to differentiate patients from controls was 1.83 × 10^(-3) mm^2/s with an area under the curve(AUC) of 0.992. Combining ADC and miR-200 b revealed the highest AUC(0.995) for differentiating patients from controls with an accuracy of 96.9%. The cut-off ADC used to differentiate early fibrosis from late fibrosis was 1.54 × 10^(-3) mm^2/s with an AUC of 0.866. The combination of ADC and miR-200 b revealed the best AUC(0.925) for differentiating early fibrosis from late fibrosis with an accuracy of 80.2%. The ADC correlated with miR-200 b(r =-0.61, P = 0.001), miR-21(r =-0.62, P = 0.001), and miR-29(r = 0.52,P = 0.001).CONCLUSION Combining ADC and miRs offers an alternative surrogate non-invasive diagnostic tool for diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C. | Tarek Besheer Hatem Elalfy Mohamed Abd El-Maksoud Ahmed Abd El-Razek Saher Taman Khaled Zalata Wagdy Elkashef Hossam Zaghloul Heba Elshahawy Doaa Raafat Wafaa Elemshaty Eman Elsayed Abdel-Hady El-Gilany Mahmoud El-Bendary | 2019 | World Journal of Gastroenterology2019，25，11： | 9 |
| 5 | Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt显示文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. | Nizar Saleh Abdelfattah Mohamed Amgad Ahmed A Salama Marina E Israel Ghada A Elhawary Ahmed E Radwan Mohamed M Elgayar Tamer M EL Nakhal Islam T Elkhateb Heba A Hashem Doha K Embaby Amira A Elabd Reem K Elwy Magdi S Yacoub Hamdy Salem Mohamed Abdel-Baqy Ahmad Kassem | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 8 |
| 6 | Molecular underpinnings of corneal angiogenesis:advances over the past decade显示文摘The cornea is maintained in an avascular state by maintaining an environment whereby anti-angiogenic factors take the upper hand over factors promoting angiogenesis. Many of the common pathologies affecting the cornea involve the disruption of such equilibrium and the shift towards new vessel formation, leading to corneal opacity and eventually-vision loss. Therefore it is of paramount importance that the molecular underpinnings of corneal neovascularization(CNV) be clearly understood, in order to develop better targeted treatments. This article is a review of the literature on the recent discoveries regarding pro-angiogenic factors of the cornea(such as vascular endothelial growth factors,fibroblast growth factor and matrix metalloproteinases)and anti-angiogenic factors of the cornea(such as endostatins and neostatins). Further, we review the molecular underpinnings of lymphangiogenesis, a process now known to be almost separate from(yet related to) hemangiogenesis. | Nizar Saleh Abdelfattah Mohamed Amgad Amira A.Zayed Heba Hussein Nawal AbdEl-Baky | 2016 | International Journal of Ophthalmology(English edition)2016，9，5： | 6 |
| 7 | The NLRP3 inflammasome: a potential therapeutic target for traumatic brain injury显示文摘Although the precise mechanisms contributing to secondary brain injury following traumatic brain injury are complex and obscure,a number of studies have demonstrated that inflammatory responses are an obvious and early feature in the pathogenesis of traumatic brain injury.Inflammasomes are multiprotein complexes that prompt the stimulation of caspase-1 and subsequently induce the maturation and secretion of proinflammatory cytokines,such as interleukin-1β and interleukin-18.These cytokines play a pivotal role in facilitating innate immune responses and inflammation.Among various inflammasome complexes,the NOD-like receptor family pyrin domain-containing 3(NLRP3)inflammasome is the best characterized,a crucial role for NLRP3 has been demonstrated in various brain diseases,including traumatic brain injury.Several recent studies have revealed the contribution of NLRP3 inflammasome in identifying cellular damage and stimulating inflammatory responses to aseptic tissue injury after traumatic brain injury.Even more important,blocking or inhibiting the activation of the NLRP3 inflammasome may have substantial potential to salvage tissue damage during traumatic brain injury.In this review,we summarize recently described mechanisms that are involved in the activation and regulation of the NLRP3 inflammasome.Moreover,we review the recent investigations on the contribution of the NLRP3 inflammasome in the pathophysiology of TBI,and current advances and challenges in potential NLRP3-targeted therapies.A significant contribution of NLRP3 inflammasome activation to traumatic brain injury implies that therapeutic approaches focused on targeting specific inflammasome components could significantly improve the traumatic brain injury outcomes. | Saifudeen Ismael Heba A.Ahmed Tusita Adris Kehkashan Parveen Parth Thakor Tauheed Ishrat | 2021 | Neural Regeneration Research2021，16，1： | 5 |
| 8 | Helicobacter pylori may be an initiating factor in newly diagnosed ulcerative colitis patients: A pilot study显示文摘AIM To directly visualize Helicobacter pylori(H. pylori) by the highly sensitive and specific technique of immunohistochemical staining in colonic tissue from patients newly diagnosed with ulcerative colitis(UC).METHODS Colonoscopic biopsies from thirty patients with newly diagnosed UC and thirty controls were stained with Giemsa stain and immunohistochemical stain for detection of H. pylori in the colonic tissue. Results were confirmed by testing H. pylori Ag in the stool then infected patients were randomized to receive either anti H. pylori treatment or placebo.RESULTS Twelve/30(40%) of the UC patients were positive for H. pylori by Giemsa, and 17/30(56.6%) by immunohistochemistry stain. Among the control group 4/30(13.3%) and 6/30(20 %) were positive for H. pylori by Giemsa and immunohistochemistry staining respectively. H. pylori was significantly higher in UC than in controls(P = 0.04 and 0.007). All Giemsa positive patients and controls were positive by immunohistochemical stain. Four cases of the control group positive for H. pylori also showed microscopic features consistent with early UC.CONCLUSION H. pylori can be detected in colonic mucosa of patients with UC and patients with histological superficial ulcerations and mild infiltration consistent with early UC. There seems to be an association between UC and presence of H. pylori in the colonic tissue. Whether this is a causal relationship or not remains to be discovered. | Loai Mansour Ferial El-Kalla Abdelrahman Kobtan Sherief Abd-Elsalam Mohamed Yousef Samah Soliman Lobna Abo Ali Walaa Elkhalawany Ibrahim Amer Heba Harras Maha M Hagras Mohamed Elhendawy | 2018 | World Journal of Clinical Cases2018，6，13： | 4 |
| 9 | Preparation of PVC/PVP composite polymer membranes via phase inversion process for water treatment purposes显示文摘In this work, new composite membranes were successfully prepared via phase inversion technique using polyvinyl chloride(PVC) and polyvinylpyrrolidone(PVP) as polymers and tetrahydrofuran(THF) and N-methyl-2-pyrrolidone(NMP) as solvents. The prepared membranes have been characterized by scanning electron microscope(SEM), and fourier transforms infrared spectroscopy(FTIR). The scanning electron microscope results prove that the prepared membranes are smooth and their pores are distributed throughout the whole surface and bulk body of the membrane without any visible cracks. The stress–strain mechanical test showed an excellent mechanical behavior enhanced by the presence of PVP in the prepared membranes. The membranes performance results showed that the salt rejection reached 98% with a high flux. This, in turn, makes the prepared membranes can be applied for sea and brackish water treatment through membrane distillation technology. | Ahmed Bhran Abeer Shoaib Doaa Elsadeq Ayman El-gendi Heba Abdallah | 2018 | Chinese Journal of Chemical Engineering2018，26，4： | 4 |
| 10 | Barrett'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 | 2009 | World Journal of Gastroenterology2009，15，28： | 4 |
| 11 | Outcome of non surgical hepatic decompression procedures in Egyptian patients with Budd-Chiari显示文摘AIM: To evaluate outcome of patients with Budd-Chiari syndrome after balloon angioplasty ± stenting or transjugular intrahepatic portosystemic shunt (TIPS). METHODS: Twenty five patients with Budd-Chiari syndrome admitted to Ain Shams University Hospitals, Tropical Medicine Department were included. Twelve patients (48%) with short segment occlusion were candidates for angioplasty; with stenting in ten cases and without stenting in two. Thirteen patients (52%) had Transjugular Intrahepatic Portosystemic Shunt. Patients were followed up for 12-32 mo. RESULTS: Patency rate in patients who underwent angioplasty ± stenting was 83.3% at one year and at end of follow up. The need of revision was 41.6% with one year survival of 100%, dropped to 91.6% at end of follow up. In patients who had Transjugular Intrahepatic Portosystemic Shunt, patency rate was 92.3% at one year, dropped to 84.6% at end of follow up. The need of revision was 38.4% with one year and end of follow up survival of 100%. Patients with patent shunts showed marked improvement compared to those with occluded shunts. CONCLUSION: Morbidity and mortality following angioplasty ± stenting and TIPS are low with satisfactory outcome. Proper patient selection and management of shunt dysfunction are crucial in improvement. | Ahmed Eldorry Eman Barakat Heba Abdella Sara Abdelhakam Mohamed Shaker Amr Hamed Mohammad Sakr | 2011 | World Journal of Gastroenterology2011，17，7： | 3 |

| 19 | Towards hepatitis C virus elimination:Egyptian experience,achievements and limitations显示文摘Worldwide, more than one million people die each year from hepatitis C virus(HCV) related diseases, and over 300 million people are chronically infected with hepatitis B or C. Egypt used to be on the top of the countries with heavy HCV burden. Some countries are making advances in elimination of HCV, yet multiple factors preventing progress; remain for the majority. These factors include lack of global funding sources for treatment, late diagnosis, poor data, and inadequate screening. Treatment of HCV in Egypt has become one of the top national priorities since 2007. Egypt started a national treatment program intending to provide cure for Egyptian HCV-infected patients. Mass HCV treatment program had started using Pegylated interferon and ribavirin between 2007 and 2014. Yet, with the development of highly-effective direct acting antivirals(DAAs) for HCV, elimination of viral hepatitis has become a real possibility. The Egyptian National Committee for the Control of Viral Hepatitis did its best to provide Egyptian HCV patients with DAAs. Egypt adopted a strategy that represents a model of care that could help other countries with high HCV prevalence rate in their battle against HCV. This review covers the effects of HCV management in Egyptian real life settings and the outcome of different treatment protocols. Also, it deals with the current and future strategies for HCV prevention and screening as well as the challenges facing HCV elimination and the prospect of future eradication of HCV. | Dalia Omran Mohamed Alboraie Rania A Zayed Mohamed-Naguib Wifi Mervat Naguib Mohamed Eltabbakh Mohamed Abdellah Ahmed Fouad Sherief Sahar Maklad Heba Hamdy Eldemellawy Omar Khalid Saad Doaa Mohamed Khamiss Mohamed El Kassas | 2018 | World Journal of Gastroenterology2018，24，38： | 2 |
| 20 | Safety and efficacy of Hansenula-derived PEGylated-interferon alpha-2a and ribavirin combination in chronic hepatitis C Egyptian children显示文摘AIM:To investigate the safety and efficacy of a Hansenula-derived PEGylated(polyethylene glycol)interferon(IFN)-alpha-2a(Reiferon Retard)plus ribavirin customized regimen in treatment-na?ve and previously treated(non-responders and relapsers)Egyptian children with chronic hepatitis C infection.METHODS:Forty-six children with chronic hepatitis C virus(HCV)infection were selected from three tertiary pediatric hepatology centers.Clinical and laboratory evaluations were undertaken.Quantitative polymerase chain reaction(PCR)for HCV-RNA was performed before starting treatment,and again at 4,12,24,48,72wk during treatment and 6 mo after treatment cessation.All patients were assigned to receive a weekly subcutaneous injection of PEG-IFN-alpha-2a plus daily oral ribavirin for 12 wk.Thirty-four patients were treatment-na?ve and 12 had a previous treatment trial.Patients were then divided according to PCR results into two groups.GroupⅠincluded patients who continued treatment on a weekly basis(7-d schedule),while groupⅡincluded patients who continued treatment on a 5-d schedule.Patients from either group who were PCR-negative at week 48,but had at least one PCRpositive test during therapy,were assigned to have an extended treatment course up to 72 wk.The occurrence of adverse effects was assessed during treatment and follow up.The study was registered at www.ClinicalTrials.gov(NCT02027493).RESULTS:Only 11 out of 46(23.9%)patients showed a sustained virological response(SVR),two patients were responders at the end of treatment;however,they were lost to follow up at 6 mo post treatment.Breakthrough was seen in 18(39.1%)patients,one patient(2.17%)showed relapse and 14(30.4%)were non-responders.Male gender,short duration of infection,low viral load,mild activity,and mild fibrosis were the factors related to a better response.On the other hand,patients with high viral load and absence of fibrosis failed to respond to treatment.Before treatment,liver transaminases were elevated.After commencing treatment,they were normalized in all patients at week 4 and were maintained normal in responders till the end of treatment,while they increased again significantly in non-responders(P=0.007 and 0.003 at week 24 and 72 respectively).The 5-d schedule did not affect the response rate(1/17 had SVR).Treatment duration(whether 48 wk or extended course to 72 wk)gave similar response rates(9/36 vs 2/8 respectively;P=0.49).Type of previous treatment(short acting IFN vs PEG-IFN)did not affect the response to retreatment.On the other hand,SVR was significantly higher in previous relapsers than in previous non-responders(P=0.039).Only mild reversible adverse effects were observed and children tolerated the treatment well.CONCLUSION:Reiferon Retard plus ribavirin combined therapy was safe.Our customized regimen did not influence SVR rates.Further trials on larger numbers of patients are warranted. | Suzan El Naghi Tawhida Y Abdel-Ghaffar Hanaa El-Karaksy Elham F Abdel-Aty Mona S El-Raziky Aleef A Allam Heba Helmy Hanaa A El-Araby Behairy E Behairy Mohamed A El-Guindi Hatem El-Sebaie Aisha Y Abdel-Ghaffar Nermin A Ehsan Ahmed M El-Hennawy Mostafa M Sira | 2014 | World Journal of Gastroenterology2014，20，16： | 2 |
