3Intrahepatic biliary cystic neoplasms:Surgical results of 9 patients and literature review显示文摘AIM: To investigate the eligible management of the cystic neplasms of the liver. METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution. RESULTS: All patients were female with a median (range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients. Four patients had undergone previous laparotomy (with other diagnoses) which resulted in incomplete surgery or recurrences. Liver resection (n = 6) or enucleation (n = 3) was performed. The final diagnosis was intrahepaticbiliary cystadenoma in 8 patients and cystadenocarcinoma in 1 patient. All symptoms resolved after surgery. There has been no recurrence during a median (range) 31 (7-72) mo of follow up. CONCLUSION: In spite of the improvement in imaging modalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal (liver resection or enucleation) of these lesions yields satisfying long-term results.Ali Emre Kür■at Rahmi Serin Ilgin zden Yaman Tekant Orhan Bilge Ayd■n Alper Mine Güllüoglu Koray Güven 2011World Journal of Gastroenterology2011,17,3:15
4Ameliorative effects of bombesin and neurotensin on trinitrobenzene sulphonic acid-induced colitis,oxidative damage and apoptosis in rats显示文摘AIM:To investigate the effects of bombesin (BBS) and neurotensin (NTS) on apoptosis and colitis in an ulcerative colitis model. METHODS:In this study, a total of 50 rats were divided equally into 5 groups. In the control group, no colitis induction or drug administration was performed. Colitis was induced in all other groups. Following the induction of colitis, BBS, NTS or both were applied to three groups of rats. The remaining group (colitis group) received no treatment. On the 11th d after induction of colitis and drug treatment, blood samples were collected for TNF-α and IL-6 level studies. Malondialdehyde (MDA), carbonyl, myeloperoxidase (MPO) and caspase-3 activities, as well as histopathological findings, evaluated in colonic tissues. RESULTS:According to the macroscopic and microscopic findings, the study groups treated with BBS, NTS and BBS + NTS showed significantly lower damage and inflammation compared with the colitis group (macroscopic score, 2.1 ± 0.87, 3.7 ± 0.94 and 2.1 ± 0.87 vs 7.3 ± 0.94;microscopic score, 2.0 ± 0.66, 3.3 ± 0.82 and 1.8 ± 0.63 vs 5.2 ± 0.78, P < 0.01). TNF-α and IL-6 levels were increased significantly in all groups compared with the control group. These increases were significantly smaller in the BBS, NTS and BBS + NTS groups compared with the colitis group (TNF-α levels, 169.69 ± 53.56, 245.86 ± 64.85 and 175.54 ± 42.19 vs 556.44 ± 49.82;IL-6 levels, 443.30 ± 53.99, 612.80 ± 70.39 and 396.80 ± 78.43 vs 1505.90 ± 222.23, P < 0.05). The colonic MPO and MDA levels were significantly lower in control, BBS, NTS and BBS + NTS groups than in the colitis group (MPO levels, 24.36 ± 8.10, 40.51 ± 8.67 and 25.83 ± 6.43 vs 161.47 ± 38.24;MDA levels, 4.70 ± 1.41, 6.55 ± 1.12 and 4.51 ± 0.54 vs 15.60 ± 1.88, P < 0.05). Carbonyl content and caspase-3 levels were higher in the colitis and NTS groups than in control, BBS and BBS + NTS groups (carbonyl levels, 553.99 ± 59.58 and 336.26 ± 35.72 vs 209.76 ± 30.92, 219.76 ± 25.77 and 220.34 ± 36.95;caspase-3 levels, 451.70 ± 68.27 and 216.20 ± 28.17 vs 28.60 ± 6.46, 170.50 ± 32.37 and 166.50 ± 30.95, P < 0.05). CONCLUSION:The results of this study suggest BBS and NTS, through their anti-inflammatory actions, support the maintenance of colonic integrity and merit consideration as potential agents for ameliorating colonic inflammation.Alper Akcan Sebahattin Muhtaroglu Hulya Akgun Hizir Akyildiz Can Kucuk Erdogan Sozuer Alper Yurci Namik Yilmaz 2008World Journal of Gastroenterology2008,14,8:14
5CO_(2) utilization: Developments in conversion processes显示文摘Carbon dioxide capture,utilization and storage(CCUS)eincluding conversion to valuable chemicals-is a challenging contemporary issue having multi-facets.The prospect to utilize carbon dioxide(CO_(2))as a feedstock for synthetic applications in chemical and fuel industries-through carboxylation and reduction reactions-is the subject of this review.Current statute of the heterogeneously catalyzed hydrogenation,as well as the photocatalytic and electrocatalytic activations of conversion of CO_(2) to value-added chemicals is overviewed.Envisaging CO_(2) as a viable alternative to natural gas and oil as carbon resource for the chemical supply chain,three stages of development;namely,(i)existing mature technologies(such as urea production),(ii)emerging technologies(such as formic acid or other single carbon(C1)chemicals manufacture)and(iii)innovative explorations(such as electrocatalytic ethylene production)have been identified and highlighted.A unique aspect of this review is the exploitations of reactions of CO2 ewhich stems from existing petrochemical plants-with the commodity petrochemicals(such as,methanol,ethylene and ethylene oxide)produced at the same or nearby complex in order to obtain value-added products while contributing also to CO_(2) fixation simultaneously.Exemplifying worldwide ethylene oxide facilities,it is recognized that they produce about 3 million tons of CO2 annually.Such a CO_(2) resource,which is already separated in pure form as a requirement of the process,should best be converted to a value-added chemical there avoiding current practice of discharging to the atmosphere.The potential utilization of CO_(2),captured at power plants,should also been taken into consideration for sustainability.This CO_(2) source,which is potentially a raw material for the chemical industry,will be available at sufficient quality and at gigantic quantity upon realization of on-going tangible capture projects.Products resulting from carboxylation reactions are obvious conversions.In addition,provided that enough supply of energy from non-fossil resources,such as solar[1],is ensured,CO_(2) reduction reactions can produce several valuable commodity chemicals including multi-carbon compounds,such as ethylene and acrylic acid,in addition to C1 chemicals and polymers.Presently,there are only few developing technologies which can find industrial applications.Therefore,there is a need for concerted research in order to assess the viability of these promising exploratory technologies rationally.Erdogan Alper Ozge Yuksel 2017Petroleum2017,3,1:13
6Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13

8Solid amine sorbents for CO_(2) capture by chemical adsorption: A review显示文摘Amines are well-known for their reversible reactions with CO_(2),which make them ideal for CO_(2) capture from several gas streams,including flue gas.In this respect,selective CO_(2) absorption by aqueous alkanolamines is the most mature technology but the process is energy intensive and has also corrosion problems.Both disadvantages can be diminished to a certain extent by chemical adsorption of CO_(2) selectively.The most important element of the chemical adsorption of CO_(2) involves the design and development of a suitable adsorbent which consist of a porous support onto which an amine is attached or immobilized.Such an adsorbent is often called as solid amine sorbent.This review covers solid amine-based studies which are developed and published in recent years.First,the review examines several different types of porous support materials,namely,three mesoporous silica(MCM-41,SBA-15 and KIT-6)and two polymeric supports(PMMA and PS)for CO_(2) adsorption.Emphasis is given to the synthesis,modifications and characterizations-such as BET and PXRD data-of them.Amination of these supports to obtain a solid amine sorbent through impregnation or grafting is reviewed comparatively.Focus is given to the adsorption mechanisms,material characteristics,and synthesis methods which are discussed in detail.Significant amount of original data are also presented which makes this review unique.Finally,relevant CO_(2) adsorption(or equilibrium)capacity data,and cyclic adsorption/desorption performance and stability of important classes of solid amine sorbents are critically reviewed.These include severa PEI or TEPA impregnated adsorbents and APTES-grafted systems.Elif ErdalÜnveren Bahar Ozmen Monkul S¸erife Sarıoglan Nesrin Karademir Erdogan Alper 2017Petroleum2017,3,1:8
9Leptin levels in the differential diagnosis between benign and malignant ascites显示文摘AIM: To evaluate the role of leptin levels in the differential diagnosis of ascites. METHODS: Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites (35 with malignancies, 30 cirrhosis and 12 tuberculosis). Control serum samples were obtained from 20 healthy subjects. Leptin and TNFα levels were measured by ELISA. Body mass index (BMI) and percentage of body fat (BFM) by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients. RESULTS: In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls. CONCLUSION: In patients with malignant ascites, levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.Mehmet Buyukberber Mehmet Koruk M Cemil Savas Murat T Gulsen Yavuz Pehlivan Rukiye Deveci Alper Sevinc Serdar Gergerlioglu 2007World Journal of Gastroenterology2007,13,3:7
10Early detection of response to imatinib therapy for gastrointestinal stromal tumor by using 18F-FDG-positron emission tomography and computed tomography imaging显示文摘有变形胃肠的基质肿瘤的 41 年的老女性被指 18F-FDG-positron 排放断层摄影术和计算断层摄影术(PET/CT ) 与 imatinib 在一个月前后扫描治疗(Glivec 收款机, Gleevec 收款机, Novartis,巴塞尔,瑞士) ,一个酷氨酸激酶禁止者(400 mg/d ) 。新陈代谢的反应在一月治疗前后被评估。最大的 standardised 举起价值(SUV ) 的减少是 79%( 从 9.8 ~ 2.1 ) 。正电子排放断层摄影术在 imatinib 治疗的一个月以后表明了完全的新陈代谢的反应。另外,以前的损害与花冠相比是计算机化的 tomographic 图象。根据 CT 图象在在治疗前后的肿瘤的尺寸没有差别。然而,新陈代谢的活动被禁止。18F-FDG-PET 是为对在有胃肠的基质肿瘤的病人的一个月 imatinib 治疗的反应的察觉的一个珍贵方法。Sabri Zincirkeser Alper Sevinc M Emin Kalender Celalettin Camci 2007World Journal of Gastroenterology2007,13,15:7
11Comparison of one and three initial monthly intravitreal ranibizumab injection in patients with macular edema secondary to branch retinal vein occlusion显示文摘AIM: To compare three initial monthly intravitreal ranibizumab(IVR) injections followed by pro re nata(PRN) dosing with one initial monthly IVR injections followed by PRN dosing for macular edema(ME) secondary to branch retinal vein occlusion(BRVO).METHODS: Forty-two eyes of 42 patients who had IVR injections for BRVO were retrospectively studied. Eighteen eyes received 1 initial IVR injection(1+PRN group) and 24 eyes received 3 monthly IVR injections(3+PRN). At 1, 3, 6 and 12mo; spectral-domain optical coherence tomography(SD-OCT) was performed. Central macular thickness(CMT), the integrity of the external limiting membrane(ELM), the presence of subretinal fluid, cyst size, the presence of inner segment/outer segment(IS/OS) defect were determined.RESULTS: At baseline the mean CMT was 521.3±153.2 μm in the 3+PRN group while it was 438.1±162.4 μm in 1+PRN group. At the final visit, mean CMT was 278.3±87.8 μm in the 3+PRN group and 285.2±74.2 μm in the 1+PRN group(P=0.079). The changes in CMT over the entire study period were also comparable in both groups(243±160 μm in the 3+PRN group, and 152.9±175.3 μm in the 1+PRN group; P=0.090). At baseline, best-corrected visual acuity(BCVA) was 0.92±0.60 logarithm of the minimal angle of resolution(logMAR) in the 3+PRN group, while it was 0.72±0.46 logMAR in the 1+PRN group. Final BCVA was 0.42±0.55 logMAR in the 3+PRN group and 0.38±0.50 logMAR in the 1+PRN group(P=0.979). Additionally, the BCVA changes from baseline to final visit were not significantly different(-0.50±0.45 logMAR in the 3+PRN group, and-0.33±0.39 logMAR in the 1+PRN group; P=0.255).CONCLUSION: No significant differences in the anatomical or functional results are found between 3+PRN and 1+PRN regimens in the patients receiving ranibizumab for ME secondary to BRVO. Intact IS/OS and baseline BCVA are good predictor of the visual gain, while baseline CMT is a good predictor of the anatomical gain.Alper Halil Bayat Akin Cakir Seyma Gülcenur Ozturan Selim Bolükbasi Burak Erden Mustafa Nuri Elcioglu 2018International Journal of Ophthalmology(English edition)2018,11,9:6
12Exact Solutions to (3+1) Conformable Time Fractional Jimbo–Miwa,Zakharov–Kuznetsov and Modified Zakharov–Kuznetsov Equations显示文摘Exact solutions to conformable time fractional (3+1)-dimensional equations are derived by using the modified form of the Kudryashov method. The compatible wave transformation reduces the equations to an ODE with integer orders. The predicted solution of the finite series of a rational exponential function is substituted into this ODE.The resultant polynomial equation is solved by using algebraic operations. The method works for the Jimbo–Miwa, the Zakharov–Kuznetsov, and the modified Zakharov–Kuznetsov equations in conformable time fractional forms. All the solutions are expressed in explicit forms.Alper Korkmaz 2017Communications in Theoretical Physics2017,67,5:6
13Noninvasive assessment of liver damage in chronic hepatitis B显示文摘AIM:To evaluate the efficacy of the aspartate aminotransferase/platelet ratio index(APRI)and neutrophillymphocyte(N/L)ratio to predict liver damage in chronic hepatitis B(CHB).METHODS:We analyzed 89 patients diagnosed with CHB by percutaneous liver biopsy and 43 healthy subjects.Liver biopsy materials were stained with hematoxylin-eosin and Masson’s trichrome.Patients’fibrosis scores and histological activity index(HAI)were calculated according to the Ishak scoring system.Fibrosis score was recognized as follows:F0-1 No/early-stage fibrosis,F2-6 significant fibrosis,F0-4 non-cirrhotic and F5-6 cirrhotic.Significant liver fibrosis was defined as an Ishak score of≥2.APRI and N/L ratio calculation was made by blood test results.RESULTS:The hepatitis B and control group showed no difference in N/L ratios while there was a significant difference in terms of APRI scores(P<0.001).Multiple logistic regression analysis revealed that the only independent predictive factor for liver fibrosis in CHB was platelet count.APRI score was significantly higher in cirrhotic patients than in non-cirrhotic patients.However,this significance was not confirmed by multiple logistic regression analysis.The optimum APRI score cut-off point to identify patients with cirrhosis was 1.01with sensitivity,specificity,positive predictive value and negative predictive value of 62%(36%-86%),74%(62%-83%),29%(13%-49%)and 92%(82%-97%),respectively.In addition,correlation analyses revealed that N/L ratio has a negative and significant relationship with HAI(r=-0.218,P=0.041).CONCLUSION:N/L ratio was negatively correlated with HAI.APRI score may be useful to exclude cirrhosis in CHB patients.Mehmet Celikbilek Serkan Dogan Sebnem Gursoy Gokmen Zararsιz Alper Yurci Omer Ozbakιr Kadri Guven Mehmet Yucesoy 2013World Journal of Hepatology2013,5,8:5

15Rhabdomyolysis 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 2017World Journal of Clinical Pediatrics2017,6,4:5
16Effect of sunitinib on metastatic gastrointestinal stromal tumor in patients with neurofibromatosis type 1: A case report显示文摘Gastrointestinal stromal tumor (GIST) represents the most common mesenchymal malignancy of the gastrointestinal (GI) tract. In neurofibromatosis (NF), the increased incidence of tumor needs to be considered even in non-symptomatic individuals. Patients with neurofibromatosis NF type 1 have an increased risk of developing GI tumors including rare types such as GIST. We report a case of GIST in a 53-year-old male patient with neurofibromatosis. The patient was diagnosed with NF four years ago and his medical history revealed that he was hospitalized 5 times with a provisional diagnosis of massive lower gastrointestinal bleeding. GIST was diagnosed at explorative laparotomy and the tumor was 21 cm × 13 cm × 7 cm in size. Immunohistochemical examination showed that vimentin, actin and CD117 were positive. Computerized tomography showed peritoneal implants three months later. Imatinib mesylate (600 mg/d) was initiated. However, control computerized tomography revealed liver and omental metastasis. The dosage was elevated to 800 mg/d. Despite high dosage, the progression of the metastatic lesions continued in the liver and omentum. The patient started oral sunitinib malate (Sutent? Pfizer Inc, New York, NY, USA) 50 mg per day for 4 consecutive weeks, followed by 2 wk off per treatment cycle. The metastatic lesions in the liver and omentum were decreased in size after four courses, suggesting that sunitinib is also an effective treatment modality for metastatic GIST in NF patients.M Emin Kalender Alper Sevinc Ediz Tutar Akif Sirikci Celalettin Camci 2007World Journal of Gastroenterology2007,13,18:5
17Melatonin reduces bacterial translocation and apoptosis in trinitrobenzene sulphonic acid-induced colitis of rats显示文摘AIM: To investigate the effects of exogenous melatonin on bacterial translocation and apoptosis in a rat ulcerati-ve colitis model. METHODS: Rats were randomly assigned to three groups: groupⅠ: control, group Ⅱ: experimental colitis, group Ⅲ: colitis plus melatonin treatment. On d 11 after colitis, plasma tumor necrosis factor-α, portal blood endotoxin levels, colon tissue myeloperoxidase and caspase-3 activity were measured. Bacterial translocation was quantified by blood, lymph node, liver and spleen culture. RESULTS: We observed a significantly reduced inciden-ce of bacterial translocation to the liver, spleen, mesen-teric lymph nodes, portal and systemic blood in animals treated with melatonin. Treatment with melatonin signifi-cantly decreased the caspase-3 activity in colonic tissues compared to that in trinitrobenzene sulphonic acid-trea-ted rats (16.11 ± 2.46 vs 32.97 ± 3.91, P < 0.01). CONCLUSION: Melatonin has a protective effect on ba-cterial translocation and apoptosis.Alper Akcan Can Kucuk Erdogan Sozuer Duygu Esel Hizir Akyildiz Hulya Akgun Sabahattin Muhtaroglu Yucel Aritas 2008World Journal of Gastroenterology2008,14,6:5
18Predisposing factors and surgical outcome of complicated liver hydatid cysts显示文摘AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.Alper Akcan Erdogan Sozuer Hizir Akyildiz Zeki Yilmaz Ahmet Ozturk Altay Atalay 2010World Journal of Gastroenterology2010,16,24:4
19Correlation of neutrophil/lymphocyte and platelet/lymphocyte ratio with visual acuity and macular thickness in age-related macular degeneration显示文摘AIM:To investigate the place of neutrophil-to-lymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in the diagnosis of and prognosis for neovascular age-related macular degeneration(AMD). METHODS:One hundred AMD patients and 100 healthy controls were included in the study. Blood samples were obtained from the venous blood, which is used for routine analysis, and these samples were subjected to complete blood count. NLR was defined as the neutrophil count divided by the number of lymphocytes, and PLR was defined as the platelet count divided by the number of lymphocytes. RESULTS:No statistically significant difference was observed between the two groups under consideration in terms of demographic features(P>0.05). The average NLR in the patient group was found to be significantly higher than that in the healthy control group(P<0.05). The average PLR was significantly higher in the patient group as compared to the control group(P<0.05). As best corrected visual acuity(BCVA) increased, both NLR and PLR decreased(significant negative correlations at 49.8% and 63.0%, respectively), whereas as central macular thickness(CMT) increased, both NLR and PLR increased(significant positive correlations at 59.3% and 70.0%, respectively).CONCLUSION:NLR and PLR levels are higher among neovascular AMD patients as compared to healthy control group. NLR and PLR levels were found to be inversely proportional to BCVA and directly proportional to CMT.Elvan Alper Sengul Ozgur Artunay Alev Kockar Ceyda Afacan Rifat Rasier Palmet Gun Nazli Gul Yalcin Erdal Yuzbasioglu 2017International Journal of Ophthalmology(English edition)2017,10,5:4
2023G玻璃体视网膜手术治疗孔源性视网膜脱离(英文)显示文摘目的:报告23G玻璃体视网膜手术治疗孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)的有效性和安全性。方法:本回顾性研究中,49例49眼RRD患者于2007-01/2009-07在我院行23G经巩膜无缝线玻璃体切除术纳入研究。结果:平均随访时间8.9±7.7mo(1~28mo)。47眼(95.9%)视网膜再次脱离经一次手术治愈,2眼因新出现裂孔的视网膜再次脱离通过23G经巩膜无缝线玻璃体切除术治愈。术前平均logMAR视力2.01±0.47,术后1.3±0.5(P<0.001,Paired t-test)。术前平均眼压(intraocularpressure,IOP)14.1±2.8mmHg,术后1d平均眼压12.3±3.6mmHg,术后1wk平均眼压13.1±2.1mmHg,术后1mo平均眼压14.3±2.2mmHg。术中医源性周边视网膜裂孔1眼(2.0%)。巩膜或结膜切口不要求缝合,无1眼需要转换为20G玻璃体切除术。结论:23G经巩膜无缝线玻璃体切除术可以有效,安全的治疗RRD。Ates Yanyali Gokhan Celik Alper Dincyildiz Fatih Horozoglu Ahmet F.
