| 1 | Solitary fibrous tumors in abdomen and pelvis:Imaging characteristics and radiologic-pathologic correlation显示文摘AIM:To describe the imaging features of solitary fibrous tumors(SFTs)in the abdomen and pelvis,and the clinical and pathologic correlations.METHODS:Fifteen patients with pathologically confirmed SFTs in the abdomen and pelvis were retrospectively studied with imaging techniques by two radiologists in consensus.Patients underwent unenhanced and contrast-enhanced imaging,as follows:3 with computed tomography(CT)and magnetic resonance imaging(MRI)examination,8 with CT examination only,and 4 with MRI examination only.Image characteristics such as size,shape,margin,attenuation or intensity,and pattern of enhancement were analyzed and correlated with the microscopic findings identified from surgical specimens.In addition,patient demographics,presentation,and outcomes were recorded.RESULTS:Of the 15 patients evaluated,local symptoms related to the mass were found in 11 cases at admission.The size of the mass ranged from 3.4 to 25.1cm(mean,11.5 cm).Nine cases were round or oval,6were lobulated,and 10 displaced adjacent organs.Unenhanced CT revealed a heterogeneous isodense mass in 7 cases,homogeneous isodense mass in 3 cases,and punctuated calcification in one case.On MRI,most of the lesions(6/7)were heterogeneous isointense and heterogeneous hyperintense on T1-weighted images and T2-weighted images,respectively.All tumors showed moderate to marked enhancement.Heterogeneous enhancement was revealed in 11 lesions,and 7of these had cysts,necrosis,or hemorrhage.Early nonuniform enhancement with a radial area that proved to be a fibrous component was observed in 4 lesions,which showed progressive enhancement in the venous and delayed phase.No statistical difference in the imaging findings was observed between the histologically benign and malignant lesions.Three patients had local recurrence or metastasis at follow-up.CONCLUSION:Abdominal and pelvic SFTs commonly appeared as large,solid,well-defined,hypervascular masses with variable degrees of necrosis or cystic change that often displaced adjacent structures. | Xue-Ming Li Jing Reng Peng Zhou Ying Cao Zhu-Zhong Cheng Yan Xiao Guo-Hui Xu | 2014 | World Journal of Gastroenterology2014,20,17: | 27 |
| 2 | Risk factors of poor prognosis and portal vein tumor thrombosis after curative resection of solitary hepatocellular carcinoma显示文摘BACKGROUND:Predictors of poor prognosis of solitary hepatocellular carcinoma(SHCC),a subgroup encompassing most patients with the malignancy,are still controversial.Hence,risk factors for portal vein tumor thrombosis(PVTT) in SHCC are obscure.The present study was designed to address this issue.METHOD:Clinicopathological and follow-up data for 156 consecutive patients with SHCC following curative hepatic resection were analyzed using uni-and multi-variate analyses.RESULTS:Univariate analysis showed that PVTT,tumornode-metastasis(TNM) stage,Edmondson-Steiner grade and preoperative serum alpha-fetoprotein(AFP) level were associated with the overall and disease-free survival,whereas tumor size only influenced the overall survival.In multivariate Cox regression tests,Edmondson-Steiner grade and TNM stage were independent prognostic markers for both overall and diseasefree survival.In addition,the Chi-square test showed that AFP level and Edmondson-Steiner grade were correlated with PVTT.Among them,only Edmondson-Steiner grade was shown to be of independent significance for PVTT in multi-variate logistic regression analysis.Additionally,AFP,the sole preoperative factor for PVTT,was not adequately sensitive and specific.CONCLUSIONS:Factors relating to post-surgical prognosis and PVTT in SHCC are all tumor-related.Of these,EdmondsonSteiner grade and TNM stage might be of particular importance in survival analysis.In addition,accurate prediction of PVTT by clinicopathological parameters before surgery remains difficult. | Li Zhou Jing-An Rui Shao-Bin Wang Shu-Guang Chen Qiang Qu | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,1: | 17 |
| 3 | Clinical features of solitary necrotic nodule of the liver显示文摘BACKGROUND:Solitary necrotic nodule of the liver is a rare nonmalignant lesion.The present study aimed to clarify the clinical features of the disease. METHOD:The medical records of 51 patients with histologically confirmed solitary necrotic nodule of the liver who received surgical resection at our institution were retrospectively reviewed. RESULTS:Solitary necrotic nodule of the liver was found mainly in males(68.6%,35/51),and patients ranged in age from 5 to 69 years with a mean of 45.3.Most of the patients (72.5%)had no significant symptoms,with negative results for the serum tumor markers alpha-fetoprotein, carbohydrate antigen 19-9 and carcinoembryonic antigen. The mean diameter of the nodule was 23 mm(range 10-55 mm).Compared with ultrasonographic and computed tomography findings,the specific features of magnetic resonance imaging were more helpful for differential diagnosis of the disease. CONCLUSIONS:Solitary necrotic nodule of the liver is a rare nonmalignant lesion,showing no notable symptoms and potential complications.The pathological change of the disease is not significant over a lifetime.Conservative treatment and clinical follow-up are recommended. | Zhou, Yan-Ming Li, Bin Xu, Feng Wang, Bin Li, Dian-Qi Liu, Peng Yang, Jia-Mei | 2008 | Hepatobiliary & Pancreatic Diseases International2008,7,5: | 12 |
| 4 | Surgical strategies in the therapy of non-small cell lung cancer显示文摘Lung cancer represents the leading cause of cancer mortality worldwide. Despite improvements in preoperative staging, surgical techniques, neoadjuvant/adjuvant options and postoperative care, there are still major difficulties in significantly improving survival, especially in locally advanced non-small cell lung cancer(NSCLC). To date, surgical resection is the primary mode of treatment for stage?Ⅰ?and Ⅱ NSCLC and has become an important component of the multimodality therapy of even more advanced disease with a curative intention. In fact, in NSCLC patients with solitary distant metastases, surgical interventions have been discussed in the last years. Accordingly, this review displays the recent surgical strategies implemented in the therapy of NSCLC patients. | Feras Al-Shahrabani Daniel Vallbhmer Sebastian Angenendt Wolfram T Knoefel | 2014 | World Journal of Clinical Oncology2014,5,4: | 10 |
| 5 | New Jacobian Elliptic Function Solutions to Modified KdV Equation: Ⅰ显示文摘An extended Jacobian elliptic function expansion method presented recently by us is applied to the mKdVequation such that thirteen families of Jacobian elliptic function solutions including both new solutions and Fu's allresults are obtained. When the modulus m → 1 or 0, we can find the corresponding six solitary wave solutions and sixtrigonometric function solutions. This shows that our method is more powerful to construct more exact Jacobian ellipticfunction solutions and can be applied to other nonlinear differential equations. | YAN Zhen-Ya | 2002 | Communications in Theoretical Physics2002,,8: | 9 |
| 6 | Malignant solitary fibrous tumor involving the liver显示文摘Solitary fibrous tumors are predominantly benign and are most commonly found in the thoracic cavity and pleura; while reports exist in the literature of malignant solitary fibrous tumors and those located in extrathoracic organs, these cases are considered extremely rare. Herein, a case is reported of a malignant solitary fibrous tumor involving the liver that was diagnosed and treated in a 62-year-old woman. The patient presented with complaints of upper abdominal pain and unintentional weight loss. Computed tomography scan of the abdomen revealed a remarkably large mass, measuring 15 cm × 10 cm × 20 cm, which appeared to be unrelated to any particular organ. The intraoperative finding of a wide communication with the left liver suggested hepatic origin, and served as an indicator for tumor resection via left hemihepatectomy. The diagnosis of solitary fibrous tumor and its malignant nature was confirmed by histological and immunohistochemical examination of the resected tissues. Hepatic solitary fibrous tumor is very rare, and surgery remains the mainstay of treatment. Due to limited reports of such tumors in the literature, little can be said about the benefit of adjuvant therapy and prognosis for the rare cases with malignant histological findings. | Manuel Jakob Matthias Schneider Ingo Hoeller Urban Laffer Reto Kaderli | 2013 | World Journal of Gastroenterology2013,19,21: | 7 |
| 7 | Near-infrared fluorescence imaging of a solitary fibrous tumor of the pancreas using methylene blue显示文摘A 67-year-old female presented with unexplained abdominal pain. A contrast-enhanced computed tomography scan of the abdomen incidentally revealed a mass in the uncinate process of the pancreas. This mass was resected and based on histopathological findings, diagnosed as a solitary fibrous tumor (SFT) of the pancreas. A SFT is an extremely rare benign mesenchymal tumor that in 65% of cases affects the visceral pleura but can also affect extra-pleural sites. The intraoperative demarcation of pancreatic tumors, such as SFTs, can bechallenging. In this report, the first clear intraoperative identification of a SFT of the pancreas in a human was shown using near-infrared fluorescence and methylene blue. | Joost R van der Vorst Alexander L Vahrmeijer Merlijn Hutteman Tjalling Bosse Vincent THBM Smit Cornelis JH van de Velde John V Frangioni Bert A Bonsing | 2012 | World Journal of Gastrointestinal Surgery2012,4,7: | 7 |
| 8 | Congenital solitary coronary artery fistulas characterized by their drainage sites显示文摘Last centuries have witnessed tremendous sophistication and progress in the detection,diagnosis and treatment of coronary artery fistulas(CAFs).In many countries,CAFs were reported to be visualized and treated using several imaging techniques and different management strategies.Reports from nearly all continents of the globe have contributed to the description of CAFs,not only in Asia and Europe but also throughout North and Latin America.However,these reports have to be cautiously analyzed as many of them were published as a case report and careful interpretation is warranted due to possible publication bias.A literature search was performed using PubMed search interface to select papers dealing with congenital CAFs in adult population between 2000-2009.A total of 233 subjects were collected,and analysed according to their drainage site and treatment modality.They were divided into two subgroups:percutaneous transluminal embolization group(PTE group,n=122)and surgical ligation group(SL group,n=111).In the SL group,atherosclerotic coronary artery disease(19%)and associated congenital lesions(23%)were more prevalent compared with the PTE group(9%and 8%),respectively.Infective endocarditis was more frequently seen in the SL group besides syncope,congestive heart failure and hemopericardium.In both groups multimodality diagnostic workup composed of several non-invasive and invasive imaging techniques for fistula visualization were performed and drainage sites into the different cardiac chambers and intrathoracic great vessels were similarly distributed in the two groups. | Salah AM Said | 2010 | World Journal of Cardiology2010,2,1: | 7 |
| 9 | Dynamical understanding of loop soliton solution for several nonlinear wave equations显示文摘It has been found that some nonlinear wave equations have one-loop soliton solutions. What is the dynamical behavior of the so-called one-loop soliton solution? To answer this question, the travelling wave solutions for four nonlinear wave equations are discussed. Exact explicit parametric representations of some special travelling wave solutions are given. The results of this paper show that a loop solution consists of three different breaking travelling wave solutions. It is not one real loop soliton travelling wave solution. | Ji-bin LI Department of Mathematics, Zhejiang Normal University, Jinhua 321004, China Kunming University of Science and Technology, Kunming 650093, China | 2007 | Science China Mathematics2007,50,6: | 6 |
| 10 | Solitary rectal ulcer syndrome:Clinical features,pathophysiology,diagnosis and treatment strategies显示文摘Solitary rectal ulcer syndrome(SRUS)is an uncommon benign disease,characterized by a combination of symptoms,clinical findings and histological abnormalities.Ulcers are only found in 40%of the patients;20%of the patients have a solitary ulcer,and the rest of the lesions vary in shape and size,from hyperemic mucosa to broad-based polypoid.Men and women are affected equally,with a small predominance in women.SRUS has also been described in children and in the geriatric population.Clinical features include rectal bleeding,copious mucus discharge,prolonged excessive straining,perineal and abdominal pain,feeling of incomplete defecation,constipation,and rarely,rectal prolapse.This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen.Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions.However,the etiology remains obscure,and the condition is frequently associated with pelvic floor disorders.SRUS is difficult to treat,and various treatment strategies have been advocated,ranging from conservative management to a variety of surgical procedures.The aim of the present review is to summarize the clinical features,pathophysiology,diagnostic methods and treatment strategies associated with SRUS. | Qing-Chao Zhu Rong-Rong Shen Huan-Long Qin Yu Wang | 2014 | World Journal of Gastroenterology2014,20,3: | 6 |
| 11 | Generation and Deformation of Solitary Waves显示文摘Base on the Lagrangian description and finite differencing of the time step, the generation, propagation and deformation of solitary waves are simulated numerically by means of boundary element method. An algorithm to generate waves with any prescribed form is also implanted in the scheme, but in this research, solitary waves are studied. The numerical model is first verified by studying the case of a solitary wave impinging against a vertical wall. Time histories of evolution of a soliton running up on a sloping beach, as well as over a submerged obstacle are then presented. Applications to scattering problems due to solitary waves progressing over a slope onto a shelf are also shown. | Chou Chung-Ren Shih Ruey-Syan Professor, Dept. of Harbor and River Engineering, National Taiwan Ocean University .

| 12 | THE PROJECTION LINKAGE BETWEEN THE SPINAL DORSAL HORN NEURONS AND BOTH THE SOLITARY TRACT AND DORSAL COLUMN NUCLEI显示文摘Electrical stimulation of the solitary tract nucleus (SN) and dorsal column nuclei (DCN)as well as microelectrode recording from the lumbal spinal dorsal horn have been used tofind and identify the axonal projection of and the afferent innervation on the spinal neuronsof pentobarbital- anesthetized rats. A total of 92 neurons was recorded and identified mainly in laminae Ⅲ-Ⅴ of the lumbarspinal dorsal horn. Of them, 38 neurons were activated antidromically from stimulation ofboth the SN and DCN. The other 54 neurons responded synaptically to both the SN andDCN stimulations. The initial antidromic responses of 8 neurons in the first group werefollowed by one or more responses synaptically driven from the SN and/or DCN stimulation.Conduction velocities were in the range of A delta fibers, but faster in the antidromicresponses and slower in the synaptic responses. These results indicate that (i) some spinal neurons issue branched axons of larger-sizedA delta fibers and double project to both the SN and | 吕国蔚 孟卓 罗蕾 山上芳雄 | 1991 | Science China Chemistry1991,34,2: | 6 |

| 15 | Bifurcation and Solitary Waves of the Combined KdV and KdV Equation显示文摘Bifurcation, bistability and solitary waves of the combined KdV and mKdV equation are investigatedsystematically. At first, bifurcation and bistability are analyzed by selecting an integral constant as the bifurcationparameter. Then, different conditions expressed in terms of the bifurcation parameter are obtained for the existence ofbreather-like, algebraic, pulse-like solitary waves, and shock waves. All types of the solitary wave and shock wave solutionsare given by direct integration. Finally, an approximate analytic method by employing the interpolation polynomials iscomplete and the theoretical methods are the simplest hitherto. | HUA Cun-Cai LIU Yan-Zhu | 2002 | Communications in Theoretical Physics2002,,8: | 5 |
| 16 | ON THE Benjamin-Ono EQUATION AND ITS GENERALIZATION IN THE ATMOSPHERE显示文摘This paper deals with the nonlinear problems of the two-layer shallow water wave modelin the atmosphere by the multiple scale method and points out that a nonlinear Benjamin-Ono equation may be obtained if the meridional disturbance wind is weak. Furthermore, thealgebraic solitary waves and nonlinear periodic waves are also calculated and the breakup ofan algebraic solitary wave at the initial time into two is discussed. It is found that the waveform steepens in this process, which is similar to the triggering process of squall lines inthe atmosphere. On the other hand, we also point out that when the meridional disturbancewind is strong, we may obtain a modified Benjamin-Ono equation, i. e. the Benjamin-Ono-KDV equation. | 罗德海 | 1989 | Science China Chemistry1989,32,10: | 5 |
| 17 | Experimental and Numerical Study on the Hydrodynamic Characteristics of Solitary Waves Passing Over A Submerged Breakwater显示文摘In this study, solitary waves passing over a submerged breakwater are investigated both experimentally and numerically. A total of 9 experimental conditions are carried out, including different incident wave heights and water depths. Numerical simulations are performed using a high-order finite-difference model solving Navier–Stokes (N–S) equations. The predicted water wave elevation, velocity and pressure show good agreement with experimental data, verifying the accuracy and capacity of the numerical model. Furthermore, parametric studies are conducted by numerical modelling to examine the effects of the geometrical features of submerged dike on hydrodynamic characteristics around the breakwater. | ZHAO Xi-zeng CHENG Du ZHANG Yi-fei LI Meng-yu | 2019 | China Ocean Engineering2019,33,3: | 5 |
| 18 | Multi-lens stereo reconstruction of wave surface in a wave basin显示文摘A new method is developed to measure the wave surface elevation in a wave basin.A thin film of tiny granules floating on the free surface ensures the formation of the dot grid pattern on the wave surface.The dot grid pattern is generated by a high-brightness projector.The granule film has little influence on the wave propagation in a wave basin.The measuring system is validated by the experiments of the propagation of solitary wave in water of uniform depth.It turns out that the time series of the surface elevation measured by the multi-lens stereo reconstruction method agree well with that measured by wave gauges.The errors of the measuring system are discussed.This work sheds a light on measuring the local wave field with high precision and efficiency in laboratory. | Qian Wang Yong-liu Fang Hua Liu | 2019 | Journal of Hydrodynamics2019,31,5: | 5 |
| 19 | Contribution of Baroreflex Afferent Pathway to NPY-Mediated Regulation of Blood Pressure in Rats显示文摘Neuropeptide Y (NPY), a metabolism-related cardiovascular factor, plays a crucial role in blood pressure(BP) regulation via peripheral and central pathways. The expression of NPY receptors (Y1R/Y2R) specific to baroreflex afferents impacts on the sexually dimorphic neural control of circulation. This study was designed to investigate the expression profiles of NPY receptors in the nodose ganglion (NG) and nucleus tractus solitary (NTS) under hypertensive conditions. To this end, rats with hypertension induced by NG-nitro-L-arginine methylester (L-NAME) or high fructose drinking (HFD), and spontaneously hypertensive rats (SHRs) were used to explore the effects/mechanisms of NPY on BP using functional, molecular, and electrophysiological approaches. The data showed that BP was elevated along with baroreceptor sensitivity dysfunction in model rats;Y1R was up-or down-regulated in the NG or NTS of male and female HFD/L-NAME groups,while Y2R was only down-regulated in the HFD groups as well as in the NG of the male L-NAME group. In SHRs,Y1R and Y2R were both down-regulated in the NTS, and not in the NG. In addition to NPY-mediated energy homeostasis, leptin-melanocortin activation may be essential for metabolic disturbance-related hypertension. We found that leptin and a-melanocyte stimulating hormone (aMSH) receptors were aberrantly down-regulated in HFD rats. In addition, a-MSH concentrations were reduced and NPY concentrations were elevated in the serum and NTS at 60 and 90 min after acute leptin infusion. Electrophysiological recordings showed that the decay time-constant and area under the curve of excitatory post-synaptic currents were decreased by Y1R activation in A-types, whereas, both were increased by Y2R activation in Ah-or C-types. These results demonstrate that sex-and afferent-specific NPY receptor expression in the baroreflex afferent pathway is likely to be a novel target for the clinical management of metabolism-related and essential hypertension. | Yang Liu Shu-Yang Zhao Yan Feng Jie Sun Xiao-Long Lu Qiu-Xin Yan Ying Li Zhuo Liu Lu-Qi Wang Xun Sun Shijun Li Guo-Fen Qiao Bai-Yan Li | 2020 | Neuroscience Bulletin2020,36,4: | 5 |
| 20 | Doege-Potter syndrome by malignant solitary fibrous tumor of the liver: A case report and review of literature显示文摘BACKGROUND Solitary fibrous tumor of the liver (SFTL) is a rare occurrence with a low number of cases reported in literature. SFTL is usually benign but, 10%-20% cases are reported to be malignant with a tendency to metastasize. The majority of malignant SFTL cases are associated with a paraneoplastic hypoglycaemia defined as Doege-Potter syndrome. Surgery is the best therapeutic treatment, however, long- life follow-up is recommended. CASE SUMMARY A 74-year-old man, was admitted to the emergency department after a syncopal episode with detection of hypoglycaemia resistant to medical treatment. The computed tomography revealed a solid mass measuring 15 cm of the left liver. An open left hepatectomy was performed with complete resection of tumor. Histopathological analyses confirmed a malignant SFTL. CONCLUSION Large series with long-term follow-up have not been published neither have clinical trials been undertaken. Consequently, the methodical long-term followup of surgically treated SFTLs is strongly recommended. | Delvecchio Antonella Duda Loren Conticchio Maria Fiore Felicia Lafranceschina Stefano Riccelli Umberto Cristofano Antonella Pascazio Bianca Colagrande Anna Resta Leonardo Memeo Riccardo | 2019 | World Journal of Gastrointestinal Surgery2019,11,8: | 5 |
