| 1 | GCR-Net:3D Graph convolution-based residual network for robust reconstruction in cerenkov luminescence tomography显示文摘Cerenkov Luminescence Tomography(CLT)is a novel and potential imaging modality which can display the three-dimensional distribution of radioactive probes.However,due to severe ill-posed inverse problem,obtaining accurate reconstruction results is still a challenge for traditional model-based methods.The recently emerged deep learning-based methods can directly learn the mapping relation between the surface photon intensity and the distribution of the radioactive source,which effectively improves the performance of CLT reconstruction.However,the previously proposed deep learning-based methods cannot work well when the order of input is disarranged.In this paper,a novel 3D graph convolution-based residual network,GCR-Net,is proposed,which can obtain a robust and accurate reconstruction result from the photon intensity of the surface.Additionally,it is proved that the network is insensitive to the order of input.The performance of this method was evaluated with numerical simulations and in vivo experiments.The results demonstrated that compared with the existing methods,the proposed method can achieve efficient and accurate reconstruction in localization and shape recovery by utilizing threedimensional information. | Weitong Li Mengfei Du Yi Chen Haolin Wang Linzhi Su Huangjian Yi Fengjun Zhao Kang Li Lin Wang Xin Cao | 2023 | Journal of Innovative Optical Health Sciences2023，16，1： | 0 |
| 2 | Stem cell properties and neural differentiation of sheep amniotic epithelial cells显示文摘This study was designed to verify the stem cell properties of sheep amniotic epithelial cells and their capacity for neural differentiation. Immunofluorescence microscopy and reverse transcription-PCR revealed that the sheep amniotic epithelial cells were positive for the embryonic stem cell marker proteins SSEA-1, SSEA-3, SSEA-4, TRA-1-60 and TRA-1-81, and the totipotency-associated genes Oct-4, Sox-2 and Rex-1, but negative for Nanog. Amniotic epithelial cells expressed β-III-tubulin, glial fibrillary acidic protein, nestin and microtubule-associated protein-2 at 28 days after induction with serum-free neurobasal-A medium containing B-27. Thus, sheep amniotic epithelial cells could differentiate into neurons expressing β-III-tubulin and microtubule-associated protein-2, and glial-like cells expressing glial fibrillary acidic protein, under specific conditions. | Xuemin Zhu Xiumei Wang Guifang Cao Fengjun Liu Yinfeng Yang Xiaonan Li Yuling Zhang Yan Mi Junping Liu Lingli Zhang | 2013 | Neural Regeneration Research2013，8，13： | 0 |
| 3 | A novel denoising framework for cerenkov luminescence imaging based on spatial information improved clustering and curvature-driven diffusion显示文摘With widely availed clinically used radionuclides,Cer enkov luminescence imaging(CLI)has become a potential tool in the field of optical molecular imaging.However,the impulse noises introduced by high-energy gamma rays that are generated during the decay of radionuclide reduce the image quality significantly,which affects the acauracy of quantitative analysis,as well as the three dimensional reconstruction.In this work,a novel denoising framework based on fuzzy dlustering and curvat ure driven difusion(CDD)is proposed to remove this kind of impulse noises.To improve the accuracy,the F u1zzy Local Information C-Means algorithm,where spatial information is evolved,is used.We evaluate the per formance of the proposed framework sys-tematically with a series of experiments,and the corresponding results demonstrate a better denoising effect than those from the commonly used median filter method.We hope this work may provide a useful data pre processing tool for CLI and its following studies. | Xin Cao Yi Sun Fei Kang Lin Wang Huangjian Yi Fengjun Zhao Linzhi Su Xiaowei He | 2018 | Journal of Innovative Optical Health Sciences2018，，4： | 0 |
| 4 | Improved local control without elective nodal radiotherapy in patients with unresectable NSCLC treated by 3D-CRT显示文摘To investigate the influence of prophylactic elec-tive nodal irradiation on the therapeutic results of definitive radiotherapy for patients with stage IIIA or stage IIIB unre-sectable non-small-cell lung cancer,55 patients with clini-cally inoperable advanced non-small-cell lung cancer were studied.After four cycles of induction chemotherapy,the patients were divided into two groups at random.In one group,the elective nodal irradiation was included in clinical tumor volume(CTV)of definitive radiotherapy(ENI group);and in the other group,elective nodal irradiation was not included in CTV(non-ENI group).For the patients in the ENI group,the mean prescription dose for gross tumor volumes was 58.4 Gy,while for the patients in the non-ENI group,it was 65.8 Gy(P<0.05).The responsive rates were 45.8%and 74.0%(P<0.05),and the rate of the elective nodal failure(ENF)was 4.2%and 11.1%,respectively.Kaplan-Meier analysis showed that the mean local-progression-free survival time was 11.0 and 15.0 months,and one-year local-failure rates were 51.9%and 24.5%(P<0.05).The median overall survival time was 13.0 and 15.0 months,respectively(P=0.084).The one-year survival rates were 55.7%and 72.5%,and two-year survival rates were 0%and 19.9%.There was no significant difference in the occurrences of radiation-associated complications between the two groups.Our results showed that omitting elective nodal irradiation did not result in a high incidence of elective nodal failure.On the contrary,it decreased local failure by increasing prescrip-tion doses to the primary diseases and lymphadenopaphy,and thereby it may further prolong the patients’survival. | YANG Kunyu CAO Fengjun WANG Jianhua LIU Li ZHANG Tao WU Gang | 2007 | Frontiers of Medicine2007，1，4： | 0 |
