| 1 | Sleeve gastrectomy plus uncut jejunojejunal bypass for the treatment of obesity and type 2 diabetes显示文摘Bariatric metabolic surgery has been confirmed as an effective,safe,and feasible method for achieving weight loss,treating obesity-related diseases,and improving the quality of life.Due to its simplicity,sleeve gastrectomy(SG)has been more commonly used in the past ten years than Roux-en-Y gastric bypass(RYGB).^([1])However,RYGB is superior to SG in terms of excess weight loss effect and type 2 diabetes mellitus(T2DM)remission over a 5-year follow-up period. | Zhiwei Zhai Ganbin Li Yu Tao Zhenjun Wang Jiagang Han | 2022 | Chinese Medical Journal2022，135，18： | 0 |
| 2 | Chinese guidelines for the application of colon cancer staging recognition systems based on artificial intelligence platforms (2021)显示文摘The incidence and mortality of colon cancer in China are increasing each year.At present,treatment selection for colon cancer patients mainly depends on imaging results,which require a large number of radiologists to interpret.In China,there is a shortage and uneven distribution of experienced radiologists,which leads to delays and bias in the evaluation of imaging data.Based on these considerations,the Colorectal Surgery Group of the Surgery Branch of the Chinese Medical Association in collaboration with experts at Beihang University has independently developed an artificial intelligence(AI)-based recognition system for the preoperative determination of colon cancer stage to partially replace the work of and relieve the pressure on radiologists.These guidelines aim to standardize the use of AI-based recognition systems in the preoperative staging of colon cancer and guide their clinical application. | Yun Lu Shuai Li Yuan Gao Yong Dai Bo Feng Fanghai Han Jiagang Han Jingjing He Xinxiang Li Guole Lin Qian Liu Guiying Wang Quan Wang Zhenning Wang Zheng Wang Aiwen Wu Bin Wu Yingchi Yang Hongwei Yao Wei Zhang Jianping Zhou Aimin Hao Zhongtao Zhang 无 | 2021 | Intelligent Medicine2021，1，1： | 0 |
| 3 | Tailoring depolarization temperature by phase transition causing properties evolution in Bi_(0.5)(Na_(1-x)K_(x))_(0.5)TiO_(3)ceramics显示文摘(Bi_(0.5)Na_(0.5))TiO_(3)-based materials have attracted widespread attention due to large electro-strain,large remnant polarization(P r)and high Curie temperature(T C),but the existence of inherent depolarization temperature(T d)limits the temperature stability and application temperature range.In this work,we find that K/Na ratio can regulate T d(from 90℃to 246℃)of the ceramics,which confirms that the increase of K substitution can effectively improve the temperature stability of the material.The phase structure and electrical properties of Bi_(0.5)(Na_(1-x)K_(x))_(0.5)TiO_(3)(BNKT x)ceramics can be well modulated by changing K/Na.In addition,BNKT x system exhibits excellent piezoelectric response at morphotropic phase boundary(MPB)of 20%BKT content(d_(33)=180 pC/N),where rhombohedral(R 3 c)phase and tetragonal(P 4 bm)phase coexist in MPB.With K further substitution,BNKT x ceramics transform into tetragonal phase,and the domain size grows due to the structural transition from short-range-correlated P 4 bm to long-range-correlated P 4 mm.The deferment of T d is also tightly related to the increase of P 4 mm/P 4 bm ratio.This work can provide an effective way to tailor depolarization temperature and electrical properties of BNT-based ceramics. | Diyan Yang Jihui Han Jie Yin Haoyue Xue Jiagang Wu | 2022 | Journal of Materials Science & Technology2022，，19： | 0 |
