2The utility of point-of-care ultrasound in the assessment of volume status in acute and critically ill patients显示文摘BACKGROUND:Volume resuscitation has only been demonstrated to be effective in approximately fifty percent of patients.The remaining patients do not respond to volume resuscitation and may even develop adverse outcomes(such as acute pulmonary edema necessitating endotracheal intubation).We believe that point-of-care ultrasound is an excellent modality by which to adequately predict which patients may benefi t from volume resuscitation.DATA RESOURCES:We performed a search using PubMed,Scopus,and MEDLINE.The following search terms were used:fluid responsiveness,ultrasound,non-invasive,hemodynamic,fluid challenge,and passive leg raise.Preference was given to clinical trials and review articles that were most relevant to the topic of assessing a patient’s cardiovascular ability to respond to intravenous fl uid administration using ultrasound.RESULTS:Point-of-care ultrasound can be easily employed to measure the diameter and collapsibility of various large vessels including the inferior vena cava,common carotid artery,subclavian vein,internal jugular vein,and femoral vein.Such parameters are closely related to dynamic measures of fluid responsiveness and can be used by providers to help guide fluid resuscitation in critically ill patients.CONCLUSION:Ultrasound in combination with passive leg raise is a non-invasive,costand time-effective modality that can be employed to assess volume status and response to fluid resuscitation.Traditionally sonographic studies have focused on the evaluation of large veins such as the inferior vena cava,and internal jugular vein.A number of recently published studies also demonstrate the usefulness of evaluating large arteries to predict volume status.Ali Pourmand Matthew Pyle David Yamane Kazi Sumon Sarah E.Frasure 2019World Journal of Emergency Medicine2019,10,4:18
3Long-term success of ahmed glaucoma valve in refractory glaucoma显示文摘AIM:To evaluate the long-term results and complications of ahmed glaucoma valve (AGV) implantation in refractory glaucoma.· METHODS:A retrospective review of 13 patients (13 eyes) with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 18 months was performed.All patients underwent a complete ophthalmologic examination and intraocular pressure (IOP) measurement before surgery and at 1 month,3 months,6 months,1 year after surgery and yearly afterwards.Complications and the number of antiglaucoma medications needed were recorded.· RESULTS:Mean age was 27.3±16.0 years.All eyes (100%) had at least one prior incisional surgery.Mean follow-up was 61.3±30.8 months.IOP was reduced from a mean of 35.0±7.0mmHg to 18.2±7.9mmHg at 12 months and to 17.0±4.1mmHg at 96 months (P <0.05) with a lower number of medications from baseline,76.9% patients required additional procedures to achieve the success criteria set by previously published series.The most common complications were encapculated cyst formation in eight eyes (61.5%) and tube exposure in four eyes (30.8%).· CONCLUSION:Encapsulated cyst formation was the most common complication which hindered succesful IOP control after AGV implant insertion for refractory glaucoma.Despite cyst excision with anti-fibrotic agents,successful IOP reduction was not achieved in 76.9% of the patients without antiglaucoma medication.Mahmut Kaya Zeynep Ozbek Aylin Yaman Ismet Durak 2012International Journal of Ophthalmology(English edition)2012,5,1:15
4Intrahepatic 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
5AFP level and histologic differentiation predict the survival of patients with liver transplantation for hepatocellular carcinoma显示文摘BACKGROUND: In liver transplantation or resection for hepatocellular carcinoma (HCC), patient selection depends on morphological features. In patients with HCC, we performed a clinicopathological analysis of risk factors that affected survival after liver transplantation. METHODS: In 389 liver transplantations performed from 2004 to 2010, 102 were for HCC patients. Data were collected retrospectively from the Organ Transplantation Center Database. Variables were as follows: age, gender, preoperative alpha-fetoprotein (AFP) levels, Child-Pugh and MELD scores, prognostic staging criteria (Milan and UCSF), etiology, number of tumors, the largest tumor size, total tumor size, multifocality, intrahepatic portal vein tumor thrombosis, bilobarity, and histological differentiation. RESULTS: One hundred and two patients were evaluated. The 5-year overall survival rate was 56.5%. According to the UCSF criteria, 63% of the patients were within and 37% were beyond UCSF (P=0.03). Ten patients were excluded (one with fibrolamellary HCC and 9 because of early postoperative death without HCC recurrence), and 92 patients were assessed. The mean age of the patients was 56.5±6.9 years. Sixty-two patients underwent living donor liver transplantations. The mean follow-up time was 29.4±22.6 months. Fifteen patients (16.3%) died in the follow-up period due to HCC recurrence. Univariate analysis showed that AFP level, intrahepatic portal vein tumor thrombosis, histologic differentiation and UCSF criteria were significant factors related to survival and tumor recurrence. The 5-year estimated overall survival rate was 62.2% in allpatients. According to the UCSF criteria, and the 5-year overall survival rate was 66.7% within and 52.7% beyond the criteria (P=0.04). Multivariate analysis showed that AFP level and poor differentiation were independent factors. CONCLUSIONS: For proper patient selection in liver trans- plantation for HCC, prognostic criteria related to tumor biology (especially AFP level and histological differentiation) should be considered. Poor differentiation and higher AFP levels are indicators of poor prognosis after liver transplantation.Onur Yaprak Murat Akyildiz Murat Dayangac Baha Tolga Demirbas Necdet Guler Gulen Bulbul Dogusoy Yildiray Yuzer Yaman Tokat 2012Hepatobiliary & Pancreatic Diseases International2012,11,3:15

8Use of Atomic Absorption Spectrometry in Assessment of Biomonitor Plants for Lead,Cadmium and Copper Pollution显示文摘Eleven plant species were collected from the vicinity of lead-battery plant in the city of Gaziantep,Turkey.Lead,cadmium and copper concentrations in the soil and leaves of plants were determined by atomic absorption spectrometry.Lead,Cd and Cu concentrations in the soil samples taken from battery area were found to be in the ranges of 304~602,0.4~0.44 and 31~37 mg·kg-1,respectively.Significantly increased lead concentration up to 2 750 mg·kg-1 was found in the leaves of Eleagnus angustifolia L.plant.The lead concentrations in the other plant leaves taken from 50 m around battery factory followed the order Ailanthus altissima>Morus sp.>Juglans regia L.>Ficus carica L.>Cydonia oblonga Miller>Prunus x domestica L.The plants,Populus nigra L.,Eleagnus angustifolia L.and Salix sp.were found useful for Cd,and the plant,Eleagnus angustifolia L.for Pb,to be considered as potential biomonitor.Especially,leaves of trees and plants taken from the distance of 50 m from battery plant have relatively higher Pb concentrations.Therefore,people who and animals which live in this area and benefit from these soil and plants have vital risks.Gokce Kaya Mehmet Yaman 2012光谱学与光谱分析2012,32,1:9
9Glasgow coma scale and APACHE-II scores affect the liver transplantation outcomes in patients with acute liver failure显示文摘BACKGROUND:The timing and selection of patients for liver transplantation in acute liver failure are great challenges.This study aimed to investigate the effect of Glasgow coma scale(GCS)and APACHE-II scores on liver transplantation outcomes in patients with acute liver failure.METHOD:A total of 25 patients with acute liver failure were retrospectively analyzed according to age,etiology,time to transplantation,coma scores,complications and mortality.RESULTS:Eighteen patients received transplants from live donors and 7 had cadaveric whole liver transplants.The mean duration of follow-up after liver transplantation was 39.86±40.23 months.Seven patients died within the perioperative period and the 1-,3-,5-year survival rates of the patients were72%,72%and 60%,respectively.The parameters evaluated for the perioperative deaths versus alive were as follows:the mean age of the patients was 33.71 vs 28 years,MELD score was 40 vs32.66,GCS was 5.57 vs 10.16,APACHE-II score was 23 vs 18.11,serum sodium level was 138.57 vs 138.44 mmol/L,mean waiting time before the operation was 12 vs 5.16 days.Low GCS,high APACHE-II score and longer waiting time before the operation(P<0.01)were found as statistically significant factors for perioperative mortality.CONCLUSION:Lower GCS and higher APACHE-II scores are related to poor outcomes in patients with acute liver failure after liver transplantation.Necdet Guler Omer Unalp Ayse Guler Onur Yaprak Murat Dayangac Murat Sozbilen Murat Akyildiz Yaman Tokat 2013Hepatobiliary & Pancreatic Diseases International2013,12,6:9
10Serrated pathway in colorectal carcinogenesis显示文摘Serrated adenocarcinoma is a recently described subset of colorectal cancer(CRC),which account for about10%of all CRCs and follows an alternative pathway in which serrated polyps replace the traditional adenoma as the precursor lesion to CRC.Serrated polyps form a heterogeneous group of colorectal lesions that includes hyperplastic polyps(HPs),sessile serrated adenoma(SSA),traditional serrated adenoma(TSA)and mixed polyps.HPs are the most common serrated polyp followed by SSA and TSA.This distinct histogenesis is believed to have a major influence in prevention strategies,patient prognosis and therapeutic impact.Genetically,serrated polyps exhibited also a distinct pattern,with KRAS and BRAF having an important contribution to its development.Two other molecular changes that have been implicated in the serrated pathway include microsatellite instability and the CpG island methylator phenotype.In the present review we will address the current knowledge of serrated polyps,clinical pathological features and will update the most recent findings of its molecular pathways.The understanding of their biology and malignancy potential is imperative to implement a surveillance approach in order to prevent colorectal cancer development.Letícia Yamane Cristovam Scapulatempo-Neto Rui Manuel Reis Denise Peixoto Guimares 2014World Journal of Gastroenterology2014,20,10:8
11Current and future surgery strategies for spinal cord injuries显示文摘Spinal cord trauma is a prominent cause of mortality and morbidity. In developed countries a spinal cord injury(SCI) occurs every 16 min. SCI occurs due to tissue destruction, primarily by mechanical and secondarily ischemic. Primary damage occurs at the time of the injury. It cannot be improved. Following the primary injury, secondary harm mechanisms gradually result in neuronal death. One of the prominent causesof secondary harm is energy deficit, emerging from ischemia, whose main cause in the early stage, is impaired perfusion. Due to the advanced techniques in spinal surgery, SCI is still challenging for surgeons. Spinal cord doesn't have a self-repair property. The main damage occurs at the time of the injury primarily by mechanical factors that cannot be improved. Secondarily mechanisms take part in the following sections. Spinal compression and neurological deficit are two major factors used to decide on surgery. According to advanced imaging techniques the classifications systems for spinal injury has been changed in time. Aim of the surgery is to decompress the spinal channel and to restore the spinal alinement and mobilize the patient as soon as possible. Use of neuroprotective agents as well as methods to achieve cell regeneration in addition to surgery would contribute to the solution.Sedat Dalbayrak Onur Yaman Tevfik Y?lmaz 2015World Journal of Orthopedics2015,6,1:7

13Preharvest long-term exposure to UV-B radiation promotes fruit ripening and modifies stage-specific anthocyanin metabolism in highbush blueberry显示文摘Ultraviolet-B(UV-B)light(280–315 nm)is an important environmental signal that regulates plant development and photomorphogenesis,while also affecting the flavonoid pathway,including anthocyanin biosynthesis.Regarding the effects of UV-B radiation on fruits,the effects of a short-term or postharvest irradiation on fruit quality have been well-documented,but the effects of a long-term preharvest UV-B irradiation on fruit growth and coloration remain unclear.Thus,in this study,we investigated the effects of a long-term treatment involving an environmentally relevant UV-B dose on highbush blueberry(Vaccinium corymbosum)fruit.The preharvest UV-B treatment quickly promoted fruit growth and sugar accumulation,which is not commonly observed in other fruit tree species.The UV-B exposure also accelerated fruit ripening and coloration.The dual-luciferase assay proved that in blueberries,expression of VcUFGT encoding anthocyanin biosynthesis key enzyme,is positively and negatively regulated by VcMYBA1 and VcMYBC2,respectively.Throughout the fruit development stage,the UV-B treatment up-regulated VcMYBPA1 expression,which increased VcUFGT expression via VcMYBA1.In the green fruit stage,the UV-B treatment increased HY5 encoding UV receptor,which up-regulates VcMYBPA1 and down-regulates VcMYBC2,thereby promotes the accumulation of anthocyanins.On the other hand,excessive anthocyanin synthesis was inhibited by increased VcMYBC2 levels in mature fruits when exposed to UV-B light through HY5-independent pathway.In conclusion,anthocyanin-related MYB activators and repressor may coordinately balance the accumulation of anthocyanins in blueberry fruits,with UV-B treatments possibly influencing their effects in a stage-specific manner.The potential utility of preharvest UV-B treatments for improving blueberry fruit quality is discussed herein.Taishan Li Hisayo Yamane Ryutaro Tao 2021Horticulture Research2021,8,1:6

15Semaphorin 3A controls allergic and inflammatory responses in experimental allergic conjunctivitis显示文摘AIM: To assess the efficacy of topical Semaphorin 3A(SEMA3A) in the treatment of allergic conjunctivitis.METHODS: Experimental allergic conjunctivitis(EAC)mice model induced by short ragweed pollen(SRW) in 4-week-old of BALB/c mice, mice were evaluated using haematoxylin and eosin(H&E) staining, immunofluor-escence and light microscope photographs. Early phase took the samples in 24 h after instillation and late phase took the samples between 4 to 14 d after the start of treatment. The study use of topical SEMA3A(10 U, 100 U,1000 U) eye drops and subconjunctival injection of SEMA3 A with same concentration. For comparison, five types of allergy eyedrops were quantified using clinical characteristics.· RESULTS: Clinical score of composite ocular symptoms of the mice treated with SEMA3 A were significantly decreased both in the immediate phase and the late phase compared to those treated with commercial ophthalmic formulations and non-treatment mice. SEMA3 A treatment attenuates infiltration of eosinophils entering into conjunctiva in EAC mice. The score of eosinophil infiltration in the conjunctiva of SEMA3 A 1000 U-treated group were significantly lower than low-concentration of SEMA3 A treated groups and non-treated group. SEMA3 A treatment also suppressed T-cell proliferation in vitro and decreased serum total Ig E levels in EAC mice. Moreover, treatment of SEMA3 A suppressed Th2-related cytokines(IL-5, IL-13 and IL-4)and pro-inflammatory cytokines(IFN-γ, IL-17 and TNF-α)release, but increased regulatory cytokine IL-10 concentration in the conjunctiva of EAC mice.CONCLUSION: SEMA3 A as a biological agent, showed the beneficial activity in ocular allergic processes with the less damage to the intraocular tissue. It is expected that SEMA3 A may be contributed in patients with a more severe spectrum of refractory ocular allergic diseases including allergic conjunctivitis in the near future.Junmi Tanaka Hideo Tanaka Nobuhisa Mizuki Eiichi Nomura Norihiko Ito Naoko Nomura Masayuki Yamane Tomonobu Hida Yoshio Goshima Hiroshi Hatano Hisashi Nakagawa 2015International Journal of Ophthalmology(English edition)2015,8,1:5
16Ocular disorders in children with spastic subtype of cerebral palsy显示文摘AIM: To document common ocular abnormalities in children with spastic subtype of cerebral palsy (CP) and to find out whether any correlation exists between their occurance and etiologic factors.METHODS: Totally 194 patients with the diagnosis of spastic type CP were enrolled in this retrospective study. Detailed ophthalmic examinations were performed. Demographic data and neuroradiological findings were documented. Kruskal-Wallis, Mann Whitney U, Pearson Chi-square tests and Student's t tests were used in the statistical analysis.RESULTS: The mean age was 64.7±44.2 months on the first ophthalmic examination. Prevalences of diplegia (47.4%) and tetraplegia (36.1%) were found to be higher than the frequency of hemiplegia (16.5% ) in our study population. Etiologic factor was asphyxia in 60.8% of the patients. Abnormal ocular findings were present in 78.9% of the patients. Statistically significant poor vision was detected in tetraplegia group among all the spastic ubtypes of CP (P =0.000). Anisometropia and significant refractive error were found in 14.4% and 70.1% of the patients, respectively. Thirty-six children (18.6% ) had nystagmus and 107 children (55.2% ) had strabismus. Lower gestational age and birth weight were statistically higher in patients with esotropia than exotropia (P=0.009 and P =0.024, respectively). Abnormal morphology of the optic disc was present in 152 eyes (39.2% ). Severe periventricular leukomalacia (PVL) was found in 48 patients and statistically significant poor vision was detected in the presence of PVL (P =0.000).CONCLUSION:Spastic diplegic or tetraplegic CP patients with positive neuroradiological symptoms, younger gestational age and lower birth weight ought to have detailed ophthalmic examinations as early as possible to provide best visual rehabilitation.·A.Taylan Ozturk A.Tulin Berk Aylin Yaman 2013International Journal of Ophthalmology(English edition)2013,6,2:5
17Delayed perforation after endoscopic submucosal dissection for early gastric cancer: Clinical features and treatment显示文摘Perforation is an important procedural complication of endoscopic submucosal dissection(ESD) for early gastric cancer. Although the incidence of delayed perforation after ESD is low, extreme caution is necessary because many cases require surgical intervention. Among 1984 lesions of early gastric cancer treated in our hospital by ESD in 1588 patients from September 2002 through March 2015, delayed perforation developed in 4 patients(4 lesions, 0.25%). A diagnosis of delayed perforation requires prompt action, including surgical intervention when required.Takafumi Yano Satoshi Tanabe Kenji Ishido Mizutomo Azuma Takuya Wada Mizuto Suzuki Natsuko Kawanishi Sakiko Yamane Tohru Sasaki Chikatoshi Katada Tetsuo Mikami Natsuya Katada Wasaburo Koizumi 2016World Journal of Gastrointestinal Endoscopy2016,8,8:4

19Hydrogen Adsorption by Woodceramics Produced from Biomass显示文摘Hydrogen adsorption characteristics of woodceramics,made from radiata pine wood fiber boards carbonized at 1 473 K after impregnation with phenolic resin,with and without chemical treatment in an alkaline(KOH) or an acid(H 2 SO 4) solution were investigated The hydrogen adsorption capacity is improved by chemical treatment.The chemical treatment by KOH improves the adsorption capacity more than by H 2 SO 4.The improvement of the capacity level,in any solution,is dependent on the type of chemical in the solution and its concentration.The maximum hydrogen capacity measured at 93 K is mass fraction about w(H) = 2% for the woodceramics after chemical treatment in a volume fraction = 50% KOH solution,although that is about w(H) = 0.7% for one without chemical treatment.The microscopic condition of pores in the woodceramics is thought to vary after chemical treatment.TAKASAKI Akito IIJIMA Suguru YAMANE Tomoka OKABE Toshio 2012Journal of Shanghai Jiaotong university(Science)2012,17,3:4
20Clinical and therapeutic considerations of rectal lymphoma: A case report and literature review显示文摘Primary rectal lymphoma is a rare presentation of gastrointestinal lymphomas. Its clinical presentation is indistinguishable from that of rectal carcinoma. Although surgical resection is often technically feasible, optimal therapy for colorectal lymphoma has not yet been identified.We report a case of primary rectal lymphoma (nonHodgkin's large cell lymphoma of type B) with high-grade features that disappeared completely after chemoradiotherapy. This case underlines that primary treatment with systemic chemotherapy and involved-field radiotherapy can be successful for rectal lymphoma, with surgery reserved for complications and chemotherapy failures.Yilmaz Bilsel Emre Balik Sumer Yamaner Dursun Bugra 2005World Journal of Gastroenterology2005,11,3:4
