Journal of Otology 2013年第2期8卷 104-111页

作者： jiang lixin Xiao Zhiwen Department of 0torhinolaryngology Head and Neck Surgery The First Affiliated Hospital of Jinan University 510632

Objective To explore the value of computed tomography virtual endoscopy(VE) in assessing ossicular chain disruption in temporal bone fracture and ear trauma with intact tympanum. Methods High resolution spiral computerized tomography(CT) was completed in 35 cases of temporal bone fracture and 5 cases of tympanum trauma, all with intact or healed tympanum. Three-dimensional reconstruction was completed using a virtual endoscopy software. Audiological tests were conducted in all patients and evaluation of facial nerve injury in patients with facial paralysis. Patients with mild conductive deafness, ossicular chain subluxation on VE, and no facial paralysis were treated conservatively for 4-12 weeks with repeated hearing evaluation; those with facial paralysis underwent surgery if no recovery after 4- 8 weeks of conservative treatment. Patients with moderate to severe conductive hearing loss or mixed hearing loss, incus long process fracture or dislocation on VE and facial paralysis, underwent ossicular chain reconstruction and facial nerve decompression after conservative treatment for 4-8 weeks, or exploratory tympanotomy only if no facial paralysis. VE, audiological tests and facial nerve function tests were repeated in 3-6 months after surgery. Results Of the 6 cases with mild conductive hearing loss, ossicular chain subluxation and no facial paralysis, 3recovered to normal hearing spontaneously and 3 showed no significant improvement, after 4-12 weeks of conservative treatment. After conservative treatment for 4-8 weeks, 3 of the 12 cases with mild conductive deafness, ossicular chain dislocation on VE and facial paralysis recovered to normal hearing and HouseBrackmann(HB) grade I facial function from HB grade II,4 showed facial function recovery to HB grade I(n=2) or II(n=2) from HB grade III but no hearing recovery, and 5 gained no recovery and went on to receive exploratory tympanotomy and facial nerve decompression. The 11 cases with moderate to severe conduct

Earthquake Research in China 2018年第3期32卷 400-411页

作者： Yang Yanming jiang lixin Wang Zhenxiang Earthquake Agency of Inner Mongolia Autonomous Region Hohhot 010010China China Earthquake Networks Center Beijing 100045China

Attenuation relation of seismic intensity is fitted by using 152 complete isoseismic lines from65 earthquakes which were greater than MS4. 0 from 1940 to 2015 in Inner Mongolia and neighboring regions. Meanwhile,based on the difference of land form and geological structure characteristics,the study area is the divided into eastern,western and *** intensity attenuation relationships are established separately by using the LM( Levenberg-Marquardt) method and elliptic attenuation model. Comparisons are made by using the earthquake affecting field model of North China and computed results. The analytical study shows that the relation obtained represents the features of earthquake damage distribution in the areas well,and has positive meaning to guide loss assessments immediately after a destroyed earthquake.

Chinese Journal of Cancer Research 2016年第5期28卷 511-518页

作者： lixin jiang Zengwu Yao Yifei Zhang Jinchen Hu Dawei Zhao Huiyuan Zhai Xixun Wang Zhenbin Zhang Dong Wang Gastrointestinal Surgery Ward I Yantai Yuhuangding Hospital the Affiliated Hospital of Qingdao University Yantai 264000 China

Objective： To compare the numbers of positive and total lymph nodes and prognosis in gastric cancer patients whose perigastric lymph node retrieval was performed by surgeons and pathologists. Methods： We conducted a retrospective analysis of clinical and follow-up data from 1,056 patients who underwent gastric cancer D2 radical lymph node resection between January 2008 and December 2010 in the Gastrointestinal Surgery Department of Yantai Yuhuangding Hospital. The follow-up ended in December 2015. Patients were divided into two groups according to the specialty of physicians who performed the postoperative perigastric lymph node retrieval： the surgeon group （475 cases） and the pathologist group （581 cases）. The numbers of positive and total perigastric lymph nodes and the 3- and 5-year survival were compared between gastric cancer patients in the two groups overall and stratified by TNM stage （AJCC 7th Edition）. Results： Overall, the numbers of positive and total lymph nodes were significantly higher in the surgeon group than in the pathologist group （6.53±4.07 vs. 4.09±3.70, P=0.021; 29.64±11.50 vs. 20.71±8.56, P〈0.001）. Further analysis showed that the total number of lymph nodes in stage Ⅰ patients （19.40±9.62 vs. 15.45±8.59, P=0.011） and the numbers of positive and total lymph nodes in stage Ⅱ（1.38±1.08 vs. 0.87±1.55, P=0.031; 25.35±10.80 vs. 16.75±8.56, P〈0.001） and stage Ⅲ patients （8.11±6.91 vs. 6.66±5.12, P=0.026; 32.34±12.55 vs. 25.45±8.31, P〈0.001） were significantly higher in the surgeon group than in the pathologist group. The survival analysis showed that the 3- and 5-year survival of stage Ⅱ and Ⅲ patients was significantly higher in the surgeon group than in the pathologist group （82.0% vs. 73.1%, 69.5% vs. 61.2%, P=0.038; 49.2% vs. 38.9%, 36.3% vs. 28.0%; P=0.045）. Conclusions： Compared with retrieval performed by pathologists, postoperative perigastrie lymph node retrieval performed by surgeons was associated with significant increase in the total l

Three-dimensional Building Damage Simulation Based on GIS

引用

Earthquake Research in China 2012年第4期26卷 520-531页

作者： Gu Guoliang jiang lixin Earthquake Administration of Tianjin Municipality China Earthquake Networks Center

GIS technology has been applied to building damage analysis around the world. However, most previous studies focused on the application of 2-D GIS technology, and the results from traditional earthquake damage prediction are displayed in 2-D figures and charts, which is incapable of demonstrating the 3-D spatial characteristics of buildings. Taking brick-concrete building as an example, we study the characteristics of building damage, and effectively combine the information of building textures and earthquake damage. Then, we apply Google SketchUp techniques to create building models and display them with seismic damage texture in the ArcGIS Engine software development environment. In this paper we propose a solid idea for 3-D simulation of earthquake damage, which is helpful in earthquake damage prediction, virtual emergency rescue practice and earthquake knowledge education.

Spin-selective and frequency-shift meta-holography based on reconfigurable origami chiral metasurface

引用

Science China(Physics,Mechanics & Astronomy) 2024年

作者： Zhibiao Zhu lixin jiang Zhe Qin Yongfeng Li Jiafu Wang Yuxiang Jia Lin Zheng Shaobo Qu Shaanxi Key Laboratory of Artificially-Structured Functional Materials and Devices Air Force Engineering University

Origami-based reconfigurable metasurfaces have emerged as a versatile paradigm for dynamically manipulating electromagnetic(EM) waves due to their advantages, such as low manufacturing cost, lightweight, and structural deformability. Three-dimensional(3D) deformation can intensify asymmetry among structures, making origami metasurfaces particularly suitable for realizing reconfigurable chiral responses. However, previous studies have primarily focused on modulating spectral properties,such as chiral switching and resonant frequency shifting. There remains ample room for further exploration in complex wavefront manipulation and holographic imaging applications. This paper proposes a simple and efficient deformation method for origami metasurfaces that transforms a spin-insensitive planar metasurface into a 3D metasurface by folding. The breaking of mirror symmetry induces a pronounced chiral response. The binary amplitude is modulated within each pixel. When folded at angles of +θ and-θ, the designed origami metasurface generates distinct images under left-handed circularly polarized(LCP)wave incidence. Meanwhile, holographic encryption is achieved under right-handed circularly polarized(RCP) wave ***, by leveraging origami's reconfigurability, the holographic imaging's operating frequency can be shifted. The experimental results agree well with the numerical calculations and full-wave simulations, demonstrating the broad application potential of this method in areas such as multi-channel imaging, information encryption technologies, and stealth.
