1Effects of partial portal vein arterialization on the hilar bile duct in a rat model显示文摘BACKGROUND: Liver revascularization is frequently required during the enlarged radical operation for hilar cholangio carcinoma involving the hepatic artery. Researchers have carried out a number of experiments applying partial porta vein arterialization (PVA) in clinical practice. In this study we aimed to establish a theoretical basis for clinical application o partial PVA and to investigate the effects of partial PVA on ra hilar bile duct and hepatic functions. METHODS: Thirty rats were randomly and equally assigned into 3 groups: control (group A), hepatic artery ligation+bile duct recanalization (group B), and partial PVA+bile duc recanalization (group C). Proliferation and apoptosis o rat hilar bile duct epithelial cells, arteriolar counts of the peribiliary plexus (PBP) of the bile duct wall, changes in serum biochemistry, and pathologic changes in the bile duc were assessed 1 month after operation. RESULTS: The proliferation of hilar bile duct epithelial cells in group B was greater than in groups A and C (P<0.01). No apoptotic hilar bile duct epithelial cells were detected in any of the groups. The PBP arteriolar counts of the hilar bile duc wall were similar in groups A and C (P>0.05), but the coun was lower in group B than in group A (P<0.01). No statistically significant differences in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and albumin were found in the 3 groups. The gamma-glutamyltransferase value was higher in group B than in groups A and C (P<0.01) The hepatic tissues of groups A and C showed no significan abnormality. Chronic inflammatory changes in the hilar bile duct walls were observed only in group B. CONCLUSION: Partial PVA can restore the arterial blood supply of the hilar bile duct and significantly extenuate the injury to hilar bile duct epithelial cells resulting from hepatic artery ligation.Shao-Hua Guo, Chong-Hui Li,Yong-Liang Chen, Jian-Ning Song,Ai-Qun Zhang and Cheng Zhou Department of Hepatobiliary Surgery (Guo SH, Li CH, Chen YL, Song JN, Zhang AQ and Zhou C) and Department of Surgical Oncology (Guo SH), General Hospital of PLA, Beijing 100853, China 2011Hepatobiliary & Pancreatic Diseases International2011,10,5:8

3Calculation of Wave Pressure and Pressure Spectrum for Perforate-Pipe Breakwater显示文摘Standing waves are formed due to the reflection when waves meet vertical wall,thereforestrong structures are needed to keep the wall stability under the serious wave attack.For the improvementof the working condition and increase of the stability of the wall,the lower reflecting breakwaters have at-tracted close attention Reports mostly from Japanese researchers are often concerned with the wall ofcaisson equipped with open windows.In this paper a kind of hollow-pipe perforated breakwater is exam-ined which waves may partially perforate into the harbour basin.The wave in front of the wall can onlyform partial standing wave and wave force is reduced obviously.And the theoretical calculation of waveforce and analysis of wave force spectrum are all derived.Comparison between the results from theoreticalcalculation and hydraulic modeling shows reasonable agreement.Li, CZ Shi, HD Yu, DY Wang, AQ 1997China Ocean Engineering1997,12,1:3
4Electronic structure and optical property of boron doped semiconducting graphene nanoribbons显示文摘We present a system study on the electronic structure and optical property of boron doped semiconducting graphene nanoribbons using the density functional theory. Energy band structure, density of states, deformation density, Mulliken popular and optical spectra are considered to show the special electronic structure of boron doped semiconducting graphene nanoribbons. The C-B bond form is discussed in detail. From our analysis it is concluded that the Fermi energy of boron doped semiconducting graphene nanoribbons gets lower than that of intrinsic semiconducting graphene nanoribbons. Our results also show that the boron doped semiconducting graphene nanoribbons behave as p-type semiconducting and that the absorption coefficient of boron doped armchair graphene nanoribbons is generally enhanced between 2.0 eV and 3.3 eV. Therefore, our results have a great significance in developing nano-material for fabricating the nano-photovoltaic devices.CHEN AQing SHAO QingYi WANG Li DENG Feng 2011Science China(Physics,Mechanics & Astronomy)2011,54,8:2
5Simulation of high conversion efficiency and open-circuit voltages of α-si/poly-silicon solar cell显示文摘The P+ α-Si /N+ polycrystalline solar cell is molded using the AMPS-1D device simulator to explore the new high efficiency thin film poly-silicon solar cell. In order to analyze the characteristics of this device and the thickness of N+ poly-silicon, we consider the impurity concentration in the N+ poly-silicon layer and the work function of transparent conductive oxide (TCO) in front contact in the calculation. The thickness of N+ poly-silicon has little impact on the device when the thickness varies from 20 μm to 300 μm. The effects of impurity concentration in polycrystalline are analyzed. The conclusion is drawn that the open-circuit voltage (Voc) of P+ α-Si /N+ polycrystalline solar cell is very high, reaching 752 mV, and the conversion efficiency reaches 9.44%. Therefore, based on the above optimum parameters the study on the device formed by P+ α-Si/N+ poly-silicon is significant in exploring the high efficiency poly-silicon solar cell.CHEN AQing SHAO QingYi 2011Science China(Physics,Mechanics & Astronomy)2011,54,8:2
6Targeted neuromodulation of abnormal interhemispheric connectivity to promote neural plasticity and recovery of arm function after stroke: a randomized crossover clinical trial study protocol显示文摘BACKGROUND AND OBJECTIVE Despite intensive rehabilitation efforts, most stroke survivors have persistent functional disability of the paretic arm and hand. These motor impairments may be due in part to maladaptive changes in structural and functional connections between brain regions. The following early stage clinical trial study protocol describes a noninvasive brain stimulation approach to target transcallosally mediated interhemispheric connections between the ipsi- and contralesional motor cortices (iM1 and cM1) using corticocortical paired associative stimulation (ihPAS). This clinical trial aims to characterize ihPAS-induced modulation of interhemispheric connectivity and the effect on motor skill performance and learning in chronic stroke survivors.Borich MR Wolf SL Tan AQ 2019中华物理医学与康复杂志2019,41,5:2
