| 3 | Is routine drainage necessary after pancreaticoduodenectomy?显示文摘With the development of imaging technology and surgical techniques, pancreatic resections to treat pancreatic tumors, ampulla tumors, and other pancreatic diseases have increased. Pancreaticoduodenectomy, one type of pancreatic resection, is a complex surgery with the loss of pancreatic integrity and various anastomoses. Complications after pancreaticoduodenectomy such as pancreatic fistulas and anastomosis leakage are common and significantly associated with patient outcomes. Pancreatic fistula is one of the most important postoperative complications; this condition can cause intraperitoneal hemorrhage, septic shock, or even death. An effective way has not yet been found to avoid the occurrence of pancreatic fistula. In most medical centers, the frequency of pancreatic fistula has remained between 9% and 13%. The early detection and routine drainage of anastomotic fistulas, pancreatic fistulas, bleeding, or other intra-abdominal fluid collections after pancreatic resections are considered as important and effective ways to reduce postoperative complications and the mortality rate. However, many recent studies have argued that routine drainage after abdominal operations, including pancreaticoduodenectomies, does not affect the incidence of postoperative complications. Although inserting drains after pancreatic resectionscontinues to be a routine procedure, its necessity remains controversial. This article reviews studies of the advantages and disadvantages of routine drainage after pancreaticoduodenectomy and discusses the necessity of this procedure. | Qiang Wang Yong-Jian Jiang Ji Li Feng Yang Yang Di Lie Yao Chen Jin De-Liang Fu | 2014 | World Journal of Gastroenterology2014，20，25： | 7 |
| 4 | Quality of life and emotional change for middle -aged and elderly patients with diabetic retinopathy显示文摘AIM:To evaluate the SF-36, Diabetes Specificity Quality of Life Scale (DSQL) and anxiety and depression symptoms and investigate its changes in proliferative diabetic retinopathy (PDR) by vitrectomy interventions. METHODS:The present study included 108 diabetic retinopathy (DR) patients:54 with PDR and 54 with non-proliferative diabetic retinopathy (NPDR). Each healthy control group (n =54) sociodemographically matched to DR groups was established respectively. The quality of life, anxiety and depression symptoms were evaluated and analyzed on preoperative and postoperative month 1 using SF-36, DSQL and Hospital Anxiety and Depression Scale (HADS). · RESULTS:DR patients described impaired HRQL (Health Related Quality of life, SF -36) in 6 out of 8 subscales, including ‘Body Health’, ‘Body RoleFunction’,‘General Health’,‘Society Function’,‘Emotion Role Function’and‘Mental Health’. Compared with controls, DR patients (NPDR and PDR) suffered from statistically significantly impaired HRQL (SF-36 Summary score) (P< 0.05). By surgical intervention, the anxiety and depression score were significantly reduced, while the health and quality of life (SF-36 Summary scores and DSQL scores) was improved in patients with PDR (P <0.05). CONCLUSION:DR patients were affected in mentation and quality of life. Surgery interventions can improve SF-36, DSQL, anxiety and depression in PDR patients. | Yao Yu Lie Feng Yi Shao Ping Tu He-Ping Wu Xun Ding Wei-Hua Xiao | 2013 | International Journal of Ophthalmology(English edition)2013，6，1： | 6 |
| 5 | Accuracy of routine multidetector computed tomography to identify arterial variants in patients scheduled for pancreaticoduodenectomy显示文摘AIM:To assess the efficacy of cross-sectional multidetector computed tomography(MDCT) imaging without arterialreconstruction to identify aberrant right hepatic artery(RHA) and celiac artery stenosis(CAS) in patients scheduled for pancreaticoduodenectomy.METHODS:Patients with peri-ampullary and pancreatic head tumors who underwent routine preoperative MDCT and subsequent computed tomography(CT) angiography(CTA),conventional angiography or pancreaticoduodenectomy between September 2007 and August 2013 were identified.Retrospective analysis of imaging data was undertaken using CTA,conventional angiographic and surgical findings as the reference standards.The accuracy,sensitivity,specificity,positive predictive value(PPV) and negative predictive value(NPV) of MDCT in evaluation of aberrant RHA and CAS were calculated.RESULTS:A group of 458 patients met the inclusion criteria of this study to detect aberrant RHA,and 181 cases were included to identify CAS.Fifty-four(11.8%) patients were confirmed to have aberrant RHA,while 12(6.6%) patients with CAS were demonstrated.MDCT yielded an accuracy of 98.5%,sensitivity of 96.3% and specificity of 98.8% in the detection of aberrant RHA.The sensitivity,specificity,PPV and NPV of MDCT for detecting CAS were 58.3%,98.2%,70% and 97.1%,respectively.CONCLUSION:Routine MDCT is recommended such that surgeons and radiologists be alerted to the importance of arterial variants on preoperative CT scans in patients scheduled for pancreaticoduodenectomy. | Feng Yang Yang Di Ji Li Xiao-Yi Wang Lie Yao Si-Jie Hao Yong-Jian Jiang Chen Jin De-Liang Fu | 2015 | World Journal of Gastroenterology2015，21，3： | 6 |
| 6 | Computational and Experimental Study of Cooling Process in Coke Dry Quenching Experimental Shaft显示文摘Owing to its merits in energy savings, environmental protection and coke quality improvement, the Coke Dry Quenching (CDQ) technology is favorite in coke making industry today. In order to validate the mathematical model developed for the cooling process of real CDQ shaft, the one-seventh scale experimental setup was established. With the air as the working fluid and the coke as the packed bed, the coke and gas temperatures and the pressure drop in the cooling shaft were measured. A mathematical model based on the non-Darcian and non-thermal equilibrium model for the cooling process of the CDQ experimental shaft was presented. The computational results were compared to the experimental data. It was found that most numerical predictions were supported by the measured values. | Huafei Liu Xinxin Zhang Maolin Wu Yanhui Feng Yingbo Wang Dinan Wang Lie Xu Wenghua Zheng | 2002 | Journal of Thermal Science2002，11，2： | 2 |
| 7 | A review of processing of Cu/C base plate composites for interfacial control and improved properties显示文摘The increase in both power and packing densities in power electronic devices has led to an increase in the market demand for effective heat-dissipating materials with a high thermal conductivity and thermal expansion coefficient compatible with chip materials while still ensuring the reliability of the power modules.Metal matrix composites,especially copper matrix composites,containing carbon fibers,carbon nanofibers,or diamond are considered very promising as the next generation of thermalmanagement materials in power electronic packages.These composites exhibit enhanced thermal properties,as compared to pure copper,combined with lower density.This paper presents powder metallurgy and hot uniaxial pressing fabrication techniques for copper/carbon composite materials which promise to be efficient heat-dissipation materials for power electronic modules.Thermal analyses clearly indicate that interfacial treatments are required in these composites to achieve high thermal and thermomechanical properties.Control of interfaces(through a novel reinforcement surface treatment,the addition of a carbide-forming element inside the copper powders,and processing methods),when selected carefully and processed properly,will form the right chemical/mechanical bonding between copper and carbon,enhancing all of the desired thermal and thermomechanical properties while minimizing the deleterious effects.This paper outlines a variety of methods and interfacial materials that achieve these goals. | Jean-François Silvain Jean-Marc Heintz Amélie Veillere Loic Constantin Yong Feng Lu | 2020 | International Journal of Extreme Manufacturing2020，2，1： | 2 |
| 8 | Numerical and experimental study on coke size distribution in bell-type charging in the CDQ shaft显示文摘The mechanism of coke size segregation in the radial direction of pre-chamber in coke dry quenching(CDQ)shaft was investigated by experiment and numerical analysis.The experimental apparatus was a cold three-dimensional semicircle model for bell-type charging,which was used to study the influences of different kinds of bells and different stock line levels on the radial dis- tribution of coke size in the radial direction of a pre-chamber.A mathematical model was used,which is capable of estimating the radial average size distribution as well as the radial deposit distribution of each particle size for multiple size coke with a few fixed parameters.The calculated results agree well with the experimental data,which proves the reliability of both experimental study and numerical analysis. | Zhicheng Liu Yanhui Feng Xinxin Zhang Lie Xu Zhendong Yu | 2008 | Journal of University of Science and Technology Beijing2008，15，3： | 2 |

| 11 | Has“Grain for Green”threaten food security on the Loess Plateau of China?显示文摘There is debating over the question of whether the large-scale‘Grain for Green’program on the Loess Plateau of China threatens regional food security.Self-sufficiency index and cropland pressure index were used to assess food security on the Loess Plateau after the implementation of revegetation program.The results showed that the‘Grain for Green’program initially had a considerable impact on regional food security,where grain yield fell from 1999 to 2001,resulting in a lower grain self-sufficiency and increased farmland stress.Subsequently,grain yield in this region increased due to the elevated agricultural material input and increased construction of terraces and check dams.The grain self-sufficiency index would have increased to 96.55%if there were improvements to the agricultural conditions,such as fertilization and irrigation,which would have resulted in an increase in the crop yield per unit of 20%.However,the grain self-sufficiency increased to 105.25%via the construction of terraces and check dams.Thus,the government should further expand the‘Grain for Green’program in coordination with improvements to the agricultural production conditions and the construction of terraces and check dams on the Loess Plateau. | Peng Shi Zhaohong Feng Haidong Gao Peng Li Xiaoming Zhang Tiantian Zhu Zhanbin Li Guoce Xu Zongping Ren Lie Xiao | 2020 | Ecosystem Health and Sustainability2020，6，1： | 1 |
| 12 | Hybrid model for muon tomography and quantitative analysis of image quality显示文摘Muon tomography is a novel method for the non-destructive imaging of materials based on muon rays,which are highly penetrating in natural background radiation.Currently,the most commonly used imaging methods include muon radiography and muon tomography.A previously studied method known as coinciding muon trajectory density tomography,which utilizes muonic secondary particles,is proposed to image low and medium atomic number(Z)materials.However,scattering tomography is mostly used to image high-Z materials,and coinciding muon trajectory density tomography exhibits a hollow phenomenon in the imaging results owing to the self-absorption effect.To address the shortcomings of the individual imaging methods,hybrid model tomography combining scattering tomography and coinciding muon trajectory density tomography is proposed and verified.In addition,the peak signal-to-noise ratio was introduced to quantitatively analyze the image quality.Different imaging models were simulated using the Geant4 toolkit to confirm the advantages of this innovative method.The simulation results showed that hybrid model tomography can image centimeter-scale materials with low,medium,and high Z simultaneously.For high-Z materials with similar atomic numbers,this method can clearly distinguish those with apparent differences in density.According to the peak signal-to-noise ratio of the analysis,the reconstructed image quality of the new method was significantly higher than that of the individual imaging methods.This study provides a reliable approach to the compatibility of scattering tomography and coinciding muon trajectory density tomography. | Si-Yuan Luo Yu-He Huang Xuan-Tao Ji Lie He Wan-Cheng Xiao Feng-Jiao Luo Song Feng Min Xiao Xiao-Dong Wang | 2022 | Nuclear Science and Techniques2022，33，7： | 1 |
