| 1 | Rubber band ligation for 750 cases of symptomatic hemorrhoids out of 2200 cases显示文摘AIM: To study the results for the treatment of symptomatic hemorrhoids using rubber band ligation (RBL) method. METHODS: A retrospective study for 750 patients who came to the colorectal unit from June, 1998 to September, 2006, data was retrieved from archived fi les. RBL was performed using the Mc Gown applicator on an outpatient basis. The patients were asked to return to out-patient clinic for follow up at 2 wk, 1 mo, 6 mo and through telephone call every 6 mo for 2 years). RESULTS: After RBL, 696 patients (92.8%) were cured with no difference in outcome for second or third degree hemorrhoids (P = 0.31). Symptomatic recurrence was detected in 11.04% after 2 years. A total of 52 patients (6.93%) had 77 complications from RBL which required no hospitalization. Complications were pain, rectal bleeding and vaso-vagal symptoms(4.13%, 4.13% and 1.33% of patients, respectively). At 1 mo there were a significant improvement in mean SF-36 scores over baseline in five items, while after 2 years there were improvement in all items over baseline, but not significant. No significant manometeric changes after band ligation. CONCLUSION: RBL is a simple, safe and effective method for treating symptomatic second and third degree hemorrhoids as an out patient procedure with signifi cant improvement in quality of life. RBL doesn't alter ano-rectal functions. | Ayman M El Nakeeb Amir A Fikry Waleed H Omar Elyamani M Fouda Tito A El Metwally Hosam E Ghazy Sabry A Badr Mohmed Y Abu Elkhar Salih M Elawady Hisham H Abd Elmoniam Waiel W Khafagy Mosaad M Morshed Ramadan E El Lithy Mohamed E Farid | 2008 | World Journal of Gastroenterology2008，14，42： | 24 |
| 2 | Risk factors for fever and sepsis after percutaneous nephrolithotomy显示文摘Objective:Percutaneous nephrolithotomy(PCNL)is commonly used in the management of large renal stones.Postoperative infections are one of the most common complications of this procedure.The present study is to determine and assess the factors that may increase the risk to develop fever and urinary sepsis after PCNL.Methods:A total of 60 patients(38 males and 22 females)with a mean age of 40.25 years enrolled in this study in Sulaimania Teaching Hospital.Patients had renal stone disease need operation with different socioeconomic status,body mass index and different type and size of stones were included in this study.Patients with preoperative positive urine culture and sensitivity were excluded.Preoperative investigations done for all patients.All Patients received prophylactic antibiotic gentamicin intravenously at the induction of anaesthesia.Renal pelvis urine sample were taken from all patients after puncturing the pelvicalyceal system and send for culture and sensitivity.Patients were monitored closely in the postoperative period for the development of fever and sepsis.Results:Mean duration of the operations was 77.08 min ranged 40e120 min.All patients had postoperative nephrostomy tube.Seventeen(28.33%)patients developed post PCNL fever and the statistically significant factors for post PCNL fever were diabetes mellitus(DM)(p Z 0.001),stone burden(p Z 0.001),number of the stones(p<0.001),degree of hydronephrosis(p Z 0.001),duration of the operation(p<0.001),residual stones(p Z 0.001)and number of tracts(p Z 0.038).Three(5.00%)patients developed post PCNL sepsis,and the statistically significant risk factors for post PCNL sepsis were duration of the operation(p Z 0.013)and intraoperative blood loss,postoperative drop in haemoglobin(HB)level(p Z 0.046).Conclusion:DM,staghorn stones,degree of hydronephrosis,duration of the operation and number of tracts are risk factors for post PCNL fever,while number of stones,intraoperative blood loss,duration of the operation and residual stones are risk factors for post PCNL sepsis. | Aso Omer Rashid Saman Salih Fakhulddin | 2016 | Asian Journal of Urology2016，3，2： | 21 |
| 3 | Hand bone mass in rheumatoid arthritis:A review of the literature显示文摘Rheumatoid arthritis(RA) is a common chronic inflammatory disease and periarticular osteoporosis or osteopenia of the inflamed hand joints is an early feature of RA Quantitative measurement of hand bone loss may be an outcome measure for the detection of joint destruction and disease progression in early RA. This systematic review examines the published literature reporting hand bone mass in patients with RA, particularly those using the dual X-ray absorptiometry(DXA) methods The majority of the studies reported that hand bone loss is associated with disease activity, functional statusand radiological progression in early RA. Quantitative measurement of hand bone mineral density by DXA may be a useful and practical outcome measure in RA and may be predictive for radiographic progression or functional status in patients with early RA. | Gamze Kilic Salih Ozgocmen | 2015 | World Journal of Orthopedics2015，6，1： | 18 |
| 4 | Airway foreign bodies: A critical review for a common pediatric emergency显示文摘BACKGROUND:Airway foreign bodies(AFBs)is an interdisciplinary area between emergency medicine,pediatrics and otolaryngology.It is a life-threatening condition that is not infrequently seen;however,it is poorly covered in medical literature.Accidental aspiration of an element into airways is a widespread clinical scenario among children under 3 years,predominantly males.Moreover,it is the leading cause of infantile deaths and the fourth one among preschool children.DATA RESOURCES:A systemic search was conducted in July 2015 using Pub Med/Pub Med Central Database of The National Center for Biotechnology Information(NCBI)(http://gffzz16a62c593b5540ceh9xpxfo559fxx6wpp.ffgz.tsg.suse.edu.cn/).A total of 1 767 articles were identified and most of them were meta-analyses,systematic reviews,and case series.Those thoroughly discussing assessment and management of AFBs were retrieved.RESULTS:AFBs episodes may be either witnessed or missed.Presence of a witness for the inhalation is diagnostic.The later usually present with persistent active cough.A classical triad of paroxysmal cough,wheezing,and dyspnoea/decreased air entry was reported,though many presentations have inconsistent findings.Hence,diagnosis requires high index of clinical suspicion.Flexible fibro-optic bronchoscopy is the gold standard of diagnosis,whereas inhaled objects are best retrieved by rigid bronchoscopes.CONCLUSIONS:Close supervision of pediatrics is the hallmark of prevention.Caregivers should ensure a safe surrounding milieu,including the toys their offspring play with.Immediate complications result from direct obstruction or injury by the inhaled object.Alternatively,prolonged lodging traps air and induces inflammatory response causing atelectesis and pneumonia,respectively. | Alaaddin M Salih Musab Alfaki Dafalla M Alam-Elhuda | 2016 | World Journal of Emergency Medicine2016，7，1： | 16 |
| 5 | 基于双吸肥口的低压文丘里施肥器设计与试验显示文摘为降低文丘里施肥器的吸肥临界进口压力,使之适用于低压灌溉施肥系统,设计了一种双吸肥口文丘里施肥器。选取喉管收缩比、收缩段角度、扩散段角度和喉管长径比4个结构参数,采用正交试验设计方法,构建16种结构参数组合方案,运用CFD模拟技术对每种方案的吸肥性能进行模拟,以吸肥性能为评价指标确定最佳结构参数组合,并根据最佳结构参数组合试制文丘里施肥器原型样品,并在0~0.15 MPa进口压力范围内对其吸肥性能进行分析。结果表明,最佳结果参数为:喉管收缩比为0.3、收缩段角度为20?、扩散段角度为8°、喉管长径比为1.1。最佳结构文丘里施肥器试制样品实测结果与模拟分析结果一致,在相同进口压力下各个实测值均略小于模拟分析值,实测与模拟吸肥量、进口流量比、肥液浓度和吸肥效率的均方根误差分别为0.22 L/min、0.96%、0.93%和0.68%。在相同进口压力下,相比于相同结构参数的单吸肥口文丘里施肥器,模拟得出的吸肥量提高了90%,进口流量比提高了85%,肥液浓度提高了80%,吸肥效率提高了80%,表明双吸肥口施肥器的吸肥性能比单吸肥口施肥器有较大提高;双吸肥口施肥器实测临界进口压力为0.007 MPa,当进口压力为0.05 MPa时其吸肥浓度可达13.6%,与现有文丘里施肥器相比,在获得同等或更高的吸肥性能时具有更低的工作进口压力,更适用于低压滴灌系统。 | 张建阔 李加念 吴昊 马泽宇 Waleed Elnour Babekir Salih 胡赫谌 | 2017 | 农业工程学报2017，33，14： | 15 |
| 6 | Matrix metalloproteinase gene expressions might be oxidative stress targets in gastric cancer cell lines显示文摘Objective: Oxidative stress is linked to increased risk of gastric cancer and matrix metalloproteinases (MMPs) are important in the invasion and metastasis of gastric cancer. We aimed to analyze the effect of the accumulation of oxidative stress in the gastric cancer MKN-45 and 23132/87 cells following hydrogen peroxide (H 2 O 2 ) exposure on the expression patterns of MMP-1, MMP-3, MMP-7, MMP-9, MMP-10, MMP- 11, MMP-12, MMP-14, MMP-15, MMP-17, MMP-23, MMP-28, and β-catenin genes. Methods: The mRNA transcripts in the cells were determined by RT-PCR. Following H 2 O 2 exposure, oxidative stress in the viable cells was analyzed by 2',7'-dichlorofluorescein diacetate (DCFH-DA). Caffeic acid phenethyl ester (CAPE) was used to eliminate oxidative stress and the consequence of H 2 O 2 exposure and its removal on the expressions of the genes were evaluated by quantitative real-time PCR. Results: The expressions of MMP-1, MMP-7, MMP-14, MMP-15, MMP-17 and β-catenin in MKN-45 cells and only the expression of MMP-15 in 23132/87 cells were increased. Removal of the oxidative stress resulted in decrease in the expressions of MMP genes of which the expressions were increased after H 2 O 2 exposure. β-catenin, a transcription factor for many genes including MMPs, also displayed decreased levels of expression in both of the cell lines following CAPE treatment. Conclusions: Our data suggest that there is a remarkable link between the accumulation of oxidative stress and the increased expressions of MMP genes in the gastric cancer cells and MMPs should be considered as potential targets of therapy in gastric cancers due to its continuous exposure to oxidative stress. | Salih Gencer Anil Cebeci Meliha Burcu Irmak-Yazicioglu | 2013 | Chinese Journal of Cancer Research2013，25，3： | 13 |
| 7 | H pylori infection and other risk factors associated with peptic ulcers in Turkish patients: A retrospective study显示文摘AIM: To identify and evaluate the relative impact of H pylori infection and other risk factors on the occurrence of gastric ulcer (GU), duodenal ulcer (DU) and gastritis in Turkish patients. METHODS: A total of 4471 patients (48.3% female) out of 4863 attended the Samatya hospital in Istanbul (June 1999 - October 2003) were included. The records of H pylori status (CLO-test), endoscopic f indings of GU, DU and gastritis, personal habits (smoking, alcohol intake) and medication [non-steroidal anti-inflammatory drugs (NSAIDs), aspirin intake] were analyzed using multi-way frequency analysis. RESULTS: We have found that GU in the presence of H pylori had significant association with aspirin (P = 0.0001), alcohol (P = 0.0090) and NSAIDs (P = 0.0372). DU on the other hand had significant association with aspirin/ smoking/NSAIDs (P = 0.0259), aspirin/alcohol (P = 0.0002) and aspirin/smoking (P = 0.0233), also in the presence of H pylori. In the absence of H pylori GU had significant association with alcohol/NSAIDs (P = 0.0431), and NSAIDs (P = 0.0436). While DU in the absence of H pylori had significant association with smoking/alcohol/ NSAIDs (P = 0.0013), aspirin/NSAIDs (P = 0.0334), aspirin/alcohol (P = 0.0360). CONCLUSION: In the presence of H pylori, aspirin, alcohol and NSAIDs intake act as an independent risk factors that had an augmenting impact on the occurrence of GU and only together on the occurrence of DU in Turkish patients. | Barik A Salih M Fatih Abasiyanik Nizamettin Bayyurt Ersan Sander | 2007 | World Journal of Gastroenterology2007，13，23： | 11 |
| 8 | 炭纤维增强轻质矿粉混凝土的热电行为显示文摘炭纤维增强混凝土能用来感知温度,其因在于短炭纤维的P-型传导性引起的塞贝克(Seebeck)效应所致。通过测量添加炭纤维或矿质掺和物(飞灰、硅土粉)前后六种波特兰水泥基混凝土的热电功率,研究了炭纤维增强轻质混凝土热敏的能力及其矿质掺合物对Seebeck效应的影响。结果表明:炭纤维增强轻质混凝土具有类似于炭纤维增强标准混凝土的Seebeck效应,只是Seebeck系数因掺合了矿粉而减低。掺有矿粉的炭纤维增强轻质混凝土可用作建筑物的热传感器. | Bahar Demirel Salih Yazicioglu | 2008 | 新型炭材料2008，23，1： | 8 |
| 9 | Pegylated interferon-alpha plus taurine in treatment of rat liver fibrosis显示文摘AIM: To investigate the antif ibrotic effects of peginterferon- alpha 2b and taurine on oxidative stress markers and hepatocellular apoptosis. METHODS: Sixty rats with CCl4-induced liver fibrosis were divided into 4 groups (n = 15). Group 1 was left for spontaneous recovery (SR). Groups 2-4 received peginterferon-alpha 2b, taurine, and their combination, respectively, for four weeks. Histological f ibrosis scores, histomorphometric analysis, tissue hydroxyproline, tissue MDA, GPx and SOD activities were determined. Activated stellate cells and hepatocellular apoptosis were also evaluated. RESULTS: The degree of f ibrosis decreased in all treatment groups compared to spontaneous recovery group. Taurine alone and in combination with peginterferon-alpha 2b reduced oxidative stress markers, but peginterferon-alpha 2b alone did not. Apoptotic hepatocytes and activated stellate cells were higher in groups 2-4 than in group 1. Combined taurine and peginterferon-alpha 2b further reduced fibrosis and increased activated stellate cell apoptosis, but could not improve oxidative stress more than taurine alone.CONCLUSION: Peginterferon-alpha 2b exerts anti- f ibrotic effects on rat liver fibrosis. It seems ineffective against oxidative stress in vivo. Peginterferon-alpha 2b in combination with taurine seems to be an antif ibrotic strategy. | Ilker Tasci Mehmet Refik Mas Sevil Atalay Vural Salih Deveci Bilgin Comert Gunay Alcigir Nuket Mas Cemal Akay Mithat Bozdayi Cihan Yurdaydin Hakan Bozkaya Ozden Uzunalimoglu Ahmet Turan Isik Harun M Said | 2007 | World Journal of Gastroenterology2007，13，23： | 7 |
| 10 | Rhabdomyolysis with different etiologies in childhood显示文摘AIM To investigate different etiologies and management of the rhabdomyolysis in children.METHODS Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS Average diagnosis ages of eight cases were 129(24-192) ± 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection(pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase Ⅱ deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis(Meyer-Betz syndrome).CONCLUSION It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive. | Demet Alaygut Meral Torun Bayram Belde Kasap Alper Soylu Mehmet Türkmen Salih Kavukcu | 2017 | World Journal of Clinical Pediatrics2017，6，4： | 5 |
| 11 | Analysis of temporal changes in land cover and landscape metrics of a managed forest in the west Black Sea region of northern Turkey: 1970–2010显示文摘Forest structure changes continuously by natural and anthropogenic effects. Because the level of goods and services provided by forest ecosystems are related to this structure, some attributes have to be controlled while they are being managed. In this paper we describe the long-term temporal changes in land area and landscape metrics related to different land uses of a managed forest in Turkey. The study was carried out for the Daday Forest Planning Unit located in the west Black Sea region of northern Turkey. The total area is 16,813 ha and besides wood production, it is managed for erosion control, public health, aesthetics, and recreation. Stand type maps that were constructed in 1970,1989, 1999, and 2010 were used in this analysis. Transition matrixes that illustrate area changes among cover types and temporal changes on some landscape metrics were obtained using Geographic Information Systems. Stands were separated into small patches, and thus the number of patches increased nearly two-fold between 1970 and 2010. The total forest edge increased and through the associated fragmentation, the amount of core forest area decreased at the landscape scale. Landscape metrics were applied to digitized versions of historical maps to assess how forest area changed. Human use of the land has changed, forest management practices have evolved, and these along with natural forest growth have contributed to interesting changes in landscape character. | Hayati Zengin Ahmet Salih Degermenci Pete Bettinger | 2018 | Journal of Forestry Research2018，29，1： | 5 |

| 13 | The correlation between keratoconus and eye rubbing: a review显示文摘Keratoconus is a non-inflammatory disorder which is gradual in development;corneal thinning and ectatic protrusion characterizes it. Keratoconus prevalence varies between different regions depending on several factors that affecting its prevalence. There are risk factors for developing keratoconus such as demographic and environmental factors. It was suggested that eye rubbing was associated with the development of keratoconus. The main aim of this review was to summarize the literature data about keratoconus and to identify the role of eyerubbing in the aetiology of the disease. A number of 24 articles was reviewed through the Pub Med, Google Scholar and Research Gates. There are many keywords used such as keratoconus, aetiology of keratoconus, eye rubbing, keratoconus prevalence, keratoconus and eye rubbing correlation. We concluded that eye rubbing causes the thinning of keratocyte, and the degree of effect of eye rubbing depends on the period and force of performing eye rubbing. It is recommended to avoid eye rubbing to prevent keratoconus, this can be achieved by avoiding itching and treating dryness of the eye and avoiding wearing eye lenses. | Hatim Najmi Yara Mobarki Khalid Mania Bashaer Altowairqi Mohammed Basehi Mohammed Salih Mahfouz Mona Elmahdy | 2019 | International Journal of Ophthalmology(English edition)2019，12，11： | 4 |

| 18 | Optical frequency synthesizer with an integrated erbium tunable laser显示文摘Optical frequency synthesizers have widespread applications in optical spectroscopy,frequency metrology,and many other fields.However,their applicability is currently limited by size,cost,and power consumption.Silicon photonics technology,which is compatible with complementary-metal-oxide-semiconductor fabrication processes,provides a low-cost,compact size,lightweight,and low-power-consumption solution.In this work,we demonstrate an optical frequency synthesizer using a fully integrated silicon-based tunable laser.The synthesizer can be self-calibrated by tuning the repetition rate of the internal mode-locked laser.A 20 nm tuning range from 1544 to 1564 nm is achieved with~10−13 frequency instability at 10 s averaging time.Its flexibility and fast reconfigurability are also demonstrated by fine tuning the synthesizer and generating arbitrary specified patterns over time-frequency coordinates.This work promotes the frequency stability of silicon-based integrated tunable lasers and paves the way toward chip-scale lowcost optical frequency synthesizers. | Ming Xin Nanxi Li Neetesh Singh Alfonso Ruocco Zhan Su Emir Salih Magden Jelena Notaros Diedrik Vermeulen Erich P.Ippen Michael R.Watts Franz X.Kartner | 2019 | Light(Science & Applications)2019，8，1： | 2 |
| 19 | Mortality and morbidity in patients with atrial fibrillation and liver cirrhosis显示文摘BACKGROUND Atrial fibrillation(AF)is the most common cardiac arrhythmia encountered in clinical practice.However,the outcomes associated with AF in hospitalized patients with liver cirrhosis are unknown.AIM To determine the outcomes of hospitalized patients with liver cirrhosis and AF.METHODS In this study,we examined morbidity and mortality of patients with concomitant AF and liver cirrhosis from the National Inpatient Sample database,the largest publicly available inpatient healthcare database in the United States.RESULTS A total of 696937 patients with liver cirrhosis were included,45745 of whom had concomitant AF(6.6%).Liver cirrhosis patients with AF had higher rates of inhospital mortality(12.6%vs 10.3%,P<0.001),clinical stroke(1.6%vs 1.1%,P<0.001),and acute kidney injury(28.2%vs 25.1%,P<0.001),and less gastrointestinal bleeding(4.4%vs 5.1%,P<0.001)and blood transfusion(22.5%vs 23.8%,P<0.001)compared with those who did not have the arrhythmia.In addition,they had a longer length of stay(8±10 d vs 7±8 d,P<0.001)and higher hospitalization costs(20720±33210$vs 16272±24166$,P<0.001).CONCLUSION In subjects with liver cirrhosis,AF is associated with higher rates of inpatient mortality,stroke,and acute kidney injury compared to those who do not have the cardiac arrhythmia. | Yousef H Darrat Aiman Smer Claude-Samy Elayi Gustavo X Morales Fahad Alqahtani Mohamad Alkhouli John Catanzaro Jignesh Shah Mohsin Salih | 2020 | World Journal of Cardiology2020，12，7： | 2 |
| 20 | Familial chylomicronemia syndrome related chronic pancreatitis: a single-center study显示文摘BACKGROUND: Hypertriglyceridemia induces acute recurrent pancreatitis, but its role in the etiology of chronic pancreatitis(CP) is controversial. This study aimed to evaluate the clinical laboratory and radiological findings of 7 patients with CP due to type 1 hyperlipidemia compared to CP patients with other or undefined etiological factors.METHODS: We retrospectively analyzed the clinical, laboratory and radiological findings of 7 CP patients with type 1 hyper lipidemia compared to CP patients without hypertriglyceridemia These 7 patients had multiple episodes of acute pancreatitis and had features of CP on abdominal CT, endoscopic retrograde cholangiopancreatography and/or endoscopic ultrasonography.RESULTS: All CP patients were classified into two groups: a group with type 1 hyperlipidemia (n=7) and a group with other etiologies (n=58). The mean triglyceride level was 2323±894mg/dL in the first group. Age at the diagnosis of CP in the first group was significantly younger than that in the second group(16.5±5.9 vs 48.3±13.5, P<0.001). The number of episodes of acute pancreatitis in the first group was significantly higher than that in the second group (15.0±6.8 vs 4.0±4.6, P=0.011)The number of splenic vein thrombosis in the first group was significantly higher than that in the second group (4/7 vs 9/58P=0.025). Logistic regression analysis found that younger age was an independent predictor of CP due to hypertriglyceridemia(r=0.418, P=0.000).CONCLUSIONS: Type 1 hyperlipidemia appears to be an etiological factor even for a minority of patients with CP. It manifests at a younger age, and the course of the disease might be severe. | Gurhan Sisman Yusuf Erzin Ibrahim Hatemi Erkan Caglar Salih Boga Vikesh Singh Hakan Senturk | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，2： | 2 |
