| 1 | Development and validation of an endoscopic images-based deep learning model for detection with nasopharyngeal malignancies显示文摘Background:Due to the occult anatomic location of the nasopharynx and frequent presence of adenoid hyperpla-sia,the positive rate for malignancy identification during biopsy is low,thus leading to delayed or missed diagnosis for nasopharyngeal malignancies upon initial attempt.Here,we aimed to develop an artificial intelligence tool to detect nasopharyngeal malignancies under endoscopic examination based on deep learning.Methods:An endoscopic images-based nasopharyngeal malignancy detection model(eNPM-DM)consisting of a fully convolutional network based on the inception architecture was developed and fine-tuned using separate training and validation sets for both classification and segmentation.Briefly,a total of 28,966 qualified images were collected.Among these images,27,536 biopsy-proven images from 7951 individuals obtained from January 1st,2008,to December 31st,2016,were split into the training,validation and test sets at a ratio of 7:1:2 using simple randomiza-tion.Additionally,1430 images obtained from January 1st,2017,to March 31st,2017,were used as a prospective test set to compare the performance of the established model against oncologist evaluation.The dice similarity coef-ficient(DSC)was used to evaluate the efficiency of eNPM-DM in automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images,by comparing automatic segmentation with manual segmenta-tion performed by the experts.Results:All images were histopathologically confirmed,and included 5713(19.7%)normal control,19,107(66.0%)nasopharyngeal carcinoma(NPC),335(1.2%)NPC and 3811(13.2%)benign diseases.The eNPM-DM attained an overall accuracy of 88.7%(95%confidence interval(CI)87.8%-89.5%)in detecting malignancies in the test set.In the prospective comparison phase,eNPM-DM outperformed the experts:the overall accuracy was 88.0%(95%CI 86.1%-89.6%)vs.80.5%(95%CI 77.0%-84.0%).The eNPM-DM required less time(40 s vs.110.0±5.8 min)and exhibited encouraging performance in automatic segmentation of nasopharyngeal malignant area from the background,with an average DSC of 0.78±0.24 and 0.75±0.26 in the test and prospective test sets,respectively.Conclusions:The eNPM-DM outperformed oncologist evaluation in diagnostic classification of nasopharyngeal mass into benign versus malignant,and realized automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images. | Chaofeng Li Bingzhong Jing Liangru Ke Bin Li Weixiong Xia Caisheng He Chaonan Qian Chong Zhao Haiqiang Mai Mingyuan Chen Kajia Cao Haoyuan Mo Ling Guo Qiuyan Chen Linquan Tang Wenze Qiu Yahui Yu Hu Liang Xinjun Huang Guoying Liu Wangzhong Li Lin Wang Rui Sun Xiong Zou Shanshan Guo Peiyu Huang Donghua Luo Fang Qiu Yishan Wu Yijun Hua Kuiyuan Liu Shuhui Lv Jingjing Miao Yanqun Xiang Ying Sun Xiang Guo Xing Lv | 2018 | Cancer Communications2018,38,1: | 9 |
| 2 | Pre-aging on early-age behavior and bake hardening response of an Al-0.90Mg-0.80Si-0.64Zn-0.23Cu alloy显示文摘Pre-aging on early-age behavior and bake hardening response of an Al-0.90Mg-0.80Si-0.64 Zn alloy was investigated by differential scanning calorimetry(DSC), high resolution transmission electron microscopy(HRTEM), 3-dimensional atom probe(3DAP), Erichsen test and tensile test. The results indicated that pre-aged alloy exhibited excellent formability and bake-hardening response, while bake hardening response was poor in samples with natural aging. Clustering behavior during natural aging was inhibited by pre-aging. Numerous GP zones formed in pre-aged samples. GP zones were the nuclei of β′′ precipitates or directly transformed β′′ phases during paint baking process. A large number of β′′ phases were observed in pre-aged samples after paint bake treatment. There was no sign to indicate that β′′phase precipitated in natural aged samples after bake hardening treatment. | Lizhen Yan Zhihui Li Yong-an Zhang Baiqing Xiong Xiwu Li Hongwei Liu Shuhui Huang Hongwei Yan | 2016 | Progress in Natural Science:Materials International2016,26,4: | 4 |
| 3 | Effect of heat treatment on microstructures and properties of a novel Al-Zn-Mg-Cu alloy for oil drilling显示文摘In view of the special requirements for strength, heat resistance and corrosion resistance of Al-Zn-Mg-Cu alloy for oil drilling, the Al-6.2 Zn-2.5 Mg-1.6 Cu alloy was prepared by increasing Cu content on basis of Russian Series 1953 alloy. The effect of heat treatment on the microstructures and properties of the alloy was characterized by optical microscope(OM), scanning electron microscope(SEM) and transmission electron microscope(TEM), and investigated by tensile test at room temperature, thermal exposure test and corrosion test. The results show that the strength after T6 aging treatment exhibit a decrease trend as an increase of the solution temperature from465 ℃ to 480 ℃. After the solution treated by the rate of 470 ℃/1 h, second phases dissolve into the matrix very well and the strength property reaches optimum. The alloy has better comprehensive properties treated by a solution treatment of 470 ℃/1 h and then followed by an aging treatment of 120 ℃/24 h + 170 ℃/1 h + 120 ℃/24 h. Under the aging state, the precipitated phases inside the grains are suitable in size, while on the grain boundary distribute discontinuously and the precipitate-free zone is obvious. Besides, the alloy still maintain high tensile properties. The yield strength, tensile strength and elongation are 650 MPa, 686 MPa,12.0%, respectively. The yield strength retention after heat exposure is 92%. The alloy has good corrosion resistance and the exfoliation corrosion degree. The average corrosion rate in the H2S and CO2 environment is 0.0024 mm/a, which is far less than the required 0.12 mm/a. It is insensitive to H2S and CO2 environments. | Yanjun Fu Xiwu Li Kai Wen Shuhui Huang Yang Dong Mao Rao Fubo Yang Yugang Wang Baiqing Xiong Zhihui Li | 2019 | Progress in Natural Science:Materials International2019,29,2: | 2 |

| 6 | White matter regeneration induced by aligned fibrin nanofiber hydrogel contributes to motor functional recovery in canine T12 spinal cord injury显示文摘A hierarchically aligned fibrin hydrogel(AFG)that possesses soft stiffness and aligned nanofiber structure has been successfully proven to facilitate neuroregeneration in vitro and in vivo.However,its potential in promoting nerve regeneration in large animal models that is critical for clinical translation has not been sufficiently specified.Here,the effects of AFG on directing neuroregeneration in canine hemisected T12 spinal cord injuries were explored.Histologically obvious white matter regeneration consisting of a large area of consecutive,compact and aligned nerve fibers is induced by AFG,leading to a significant motor functional restoration.The canines with AFG implantation start to stand well with their defective legs from 3 to 4 weeks postoperatively and even effortlessly climb the steps from 7 to 8 weeks.Moreover,high-resolution multi-shot diffusion tensor imaging illustrates the spatiotemporal dynamics of nerve regeneration rapidly crossing the lesion within 4 weeks in the AFG group.Our findings indicate that AFG could be a potential therapeutic vehicle for spinal cord injury by inducing rapid white matter regeneration and restoring locomotion,pointing out its promising prospect in clinic practice. | Zheng Cao Weitao Man Yuhui Xiong Yi Guo Shuhui Yang Dongkang Liu He Zhao Yongdong Yang Shenglian Yao Chuzhong Li Lingyun Zhao Xiaodan Sun Hua Guo Guihuai Wang Xiumei Wang | 2022 | Regenerative Biomaterials2022,9,1: | 0 |
| 7 | Biphasic mineralized collagen-based composite scaffold for cranial bone regeneration in developing sheep显示文摘Appropriate mechanical support and excellent osteogenic capability are two essential prerequisites of customized implants for regenerating large-sized cranial bone defect.Although porous bone scaffolds have been widely proven to promote bone regeneration,their weak mechanical properties limit the clinical applications in cranioplasty.Herein,we applied two previously developed mineralized collagen-based bone scaffolds(MC),porous MC(pMC)and compact MC(cMC)to construct a biphasic MC composite bone scaffold(bMC)to repair the large-sized cranial bone defect in developing sheep.A supporting frame composed of cMC phase in the shape of tic–tac–toe structure was fabricated first and then embedded in pMC phase.The two phases had good interfacial bond,attributing to the formation of an interfacial zone.The in vivo performance of the bMC scaffold was evaluated by using a cranial bone defect model in 1-month-old sheep.The computed tomography imaging,X-ray scanning and histological evaluation showed that the pMC phase in the bMC scaffold,similar to the pMC scaffold,was gradually replaced by the regenerative bone tissues with comprehensively increased bone mineral density and complete connection of bone bridge in the whole region.The cMC frame promoted new bone formation beneath the frame without obvious degradation,thus providing appropriate mechanical protection and ensuring the structural integrity of the implant.In general,the sheep with bMC implantation exhibited the best status of survival,growth and the repair effect.The biphasic structural design may be a prospective strategy for developing new generation of cranioplasty materials to regenerate cranial bone defect in clinic. | Jingchuan Zheng Zhijun Zhao Yongdong Yang Shuo Wang Yonggang Zhao Yang Xiong Shuhui Yang Zhiye Qiu Tianxi Song Chunyang Zhang Xiumei Wang | 2022 | Regenerative Biomaterials2022,9,1: | 0 |
