| 1 | Negative pressure catheter drainage and jejunal feeding for descending necrotizing mediastinitis by interventional techniques:a retrospective study显示文摘Purpose: Descending necrotizing mediastinitis(DNM) is a lethal and acute suppurative disease. This report aimed to summarize our experience in the treatment of DNM with continuous negative pressure catheter drainage and transnasal jejunal feeding by interventional techniques. Materials and Methods: We retrospectively analyzed relevant clinical data of patients with DNM who underwent continuous negative pressure catheter drainage and transnasal jejunal feeding. All drainage catheters and jejunal feeding tubes were inserte d by interventional techniques. Results: In total, 21 patients were diagnosed with DNM by esophagography and computed tomography(CT). Catheters for the drainage of mediastinal abscesses as well as transnasal jejunal feeding tubes were successfully placed in all patients, indicating a 100% success rate. Of all patients, 13 underwent insertion of abscess drainage catheters through percutaneous puncture under DynaCT guidance, while eight had drainage catheter insertion through fistula orifices in the posterior nasopharyngeal wall or esophagus under fluoroscopic guidance. In total, 26 drainage tubes were inserted. One patient with diabetes died of sepsis and diabetic ketoacidosis 5 days postoperatively, while the remaining 20 patients showed good recovery with successful removal of the drainage catheters. Durations of catheterization were 45.2±50.44 days. The overall clinical success rate was 95.2%. Conclusion: The above described methods are non-surgical, minimally invasive and efficacious, and may be alternative therapeutic tools for patients who are not eligible for surgical operation, have a high postoperative risk, or are more likely to choose minimally invasive techniques. | Gang Wu Meipan Yin Yi Fang Gang Liu Yonggang Luo Weihong Xie Yaozhang Dai Jin Shi Xinwei Han | 2018 | Journal of Interventional Medicine2018，1，2： | 6 |
| 2 | Impact Localization of CFRP Structure Based on FBG Sensor Network显示文摘Low energy impact can induce invisible damage of carbon fiber reinforced polymer(CFRP).The damage can seriously affect the safety of the CFRP structure.Therefore,damage detection is crucial to the CFRP structure.Impact location information is the premise of damage detection.Hence,impact localization is the primary issue.In this paper,an impact localization system,based on the fiber Bragg grating(FBG)sensor network,is proposed for impact detection and localization.For the completed impact signal,the FBG sensor and narrow-band laser demodulation technology are applied.Wavelet packet decomposition is introduced to extract available frequency band signals and attenuate noise.According to the energy of the available frequency band signal,an impact localization model,based on the extreme learning machine(ELM),is established with the faster training speed and less parameters.The above system is verified on the 500 mm×500 mm×2 mm CFRP plate.The maximum localization error and the minimum localization error are 30.4 mm and 6.7 mm,respectively.The average localization error is 14.7 mm,and training time is 0.7 s.Compared with the other machine learning methods,the localization system,proposed in this paper,has higher accuracy and faster training speed.This paper provides a practical system for impact localization of the CFRP structure. | Yaozhang SAI Xiuxia ZHAO Lili WANG Dianli HOU | 2020 | Photonic Sensors2020，10，1： | 2 |

| 16 | Efficient Strip-Mode SAR Raw-Data Simulator of Extended Scenes Included Moving Targets Based on Reversion of Series显示文摘The Synthetic Aperture Radar(SAR)raw data generator is required to the evaluation of focusing algorithms,moving target analysis,and hardware design.The time-domain SAR simulator can generate the accurate raw data but it needs much time.The frequency-domain simulator not only increases the efficiency but also considers the trajectory deviations of the radar.In addition,the raw signal of the extended scene included static and moving targets can be generated by some frequency-domain simulators.However,the existing simulators concentrate on the raw signal simulation of the static extended scene and moving targets at uniform speed mostly.As for the issue,the two-dimensional signal spectrum of moving targets with constant acceleration can be derived accurately based on the geometric model of a side-looking SAR and reversion of series.And a frequency-domain algorithm for SAR echo signal simulation is presented based on the two-dimensional signal spectrum.The raw data generated with proposed method is verified by several simulation experiments.In addition to reveal the efficiency of the presented frequency-domain SAR scene simulator,the computational complexity of the proposed method is compared with the time-domain approach using the complex multiplication.Numerical results demonstrate that the present method can reduce the computational time significantly without accuracy loss while simulating SAR raw data. | Liang Yang Daojian Zeng Jianhua Yan Yaozhang Sai | 2020 | Computers, Materials & Continua2020，，7： | 0 |
