1The design philosophy and bridge's technical innovation of Hong Kong- Zhuhai-Macao Bridge显示文摘This article introduces the project overview, construction goal and design philosophy of Hong Kong- Zhuhai-Macao Bridge. Based on large scale, factory production, standardization and assemble line, the innova- tive concept is taken as the general principle for design with the emphasis on description of the new material, new technology, new construction method and new equipment used in the design. The application of innovative technology has provided a solid foundation and favorable guarantee for project quality and design serviceMeng Fanchao Liu Minghu Wu Weisheng Zhang Gejun Zhang Liang 2014Engineering Sciences2014,12,3:3
2Outcomes of Self-Expanding Transcatheter Pulmonary Valves:Extended Follow-Up of a Prospective Trial显示文摘Background:The Venus-P valve was the first self-expanding valve used world-wide for transcatheter pulmonary valve replacement(TPVR)in patients with severe pulmonary regurgitation(PR).We intended to report the extended follow-up results from the prospective trial(No.NCT02590679).Methods:A total of 38 patients with severe PR(mean age 24.2±13.2)were included.Follow-up data were obtained after implanted at 1,6,and 12 months and yearly after.The frame geometry was assessed on post-implant computer tomography(CT)scanning by calculating the non-circularity[circularity ratio(minimum diameter/maximum diameter)<0.9]and under-expansion[expansion ratio(derived external valve area/nominal external valve area)<0.9).Adverse events(all-cause mortality,reintervention,valve dysfunction,stent fracture and endocarditis)were recorded.Results:All valves were implanted successfully with normal function at discharge.Geometric CT analysis showed underexpanded valve was detected in 22 patients(63%)and non-circular valve was seen in 16 patients(46%).During a median follow-up of 4.8 years(range 0.3-8.1),there were 1 death and 1 surgical explant,both resulting from endocarditis.Five-year freedom from valve dysfunction and stent fracture were 84.8%(95%CI 74.8-94.7)and 83.5%(95%CI 73.8-93.2).Endocarditis occurred in 3 patients at a median time of 7 months.Stent fracture was more common in patients with non-circularity stents.Conclusion:TPVR using Venus-P valve is associated with favorable outcomes at 5 years.Non-circular shapes in the valve level may have a higher risk of stent fracture.Jingnan Zhang Junyi Wan Yihang Li Yu Han Jiahua Pan Fang Fang Shiliang Jiang Xiangbin Pan Gejun Zhang 2023Congenital Heart Disease2023,18,2:0
3Indications,strategies,and development on prostate targeted biopsy:Report of the Panjiayuan Consensus Conference 2022显示文摘Prostate biopsy is the gold standard for diagnosing prostate cancer(PCa).Prostate targeted biopsy(TB)having a higher rate of detecting clinically significant PCa(csPCa)than traditional systematic biopsy(SB)is supported by high-quality evidence.However,the TB indications and strategies are controversial.The National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences,invited a panel of recognized urology experts in PCa to address these topics at the Panjiayuan Consensus Conference 2022.The conference results on prostate TB are presented herein.The National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences identified 10 key areas of prostate biopsy:(1)selection of imaging examination;(2)indications of TB;(3)transperineal and transrectal prostate biopsy;(4)TB pathways;(5)TB and SB;(6)three techniques of TB;(7)the number of TB cores needed for one lesion;(8)core number for SB;(9)free-hand TB;(10)future development of TB/prostate diagnosis.Thus,a panel of 25 recognized urologists and 2 radiologists from China were invited to attend this conference.The panel voted anonymously on 14 predetermined questions.Voting was based on the panelists'clinical practice and opinion,rather than high-level evidence.The voting outcomes were supported by the panel unequally,and details of the voting results were reported.The voting results can help clinicians to decide on biopsy timing and proper strategies,for which guidelines are sparse.We also focused on the future development of TB and SB,such as the combined pathway of TB and SB,techniques of TB,biopsy cores,free-hand TB,and prostate-specific membrane antigen positron emission tomography/computed tomography.Gang Song Yajian Li Huimin Hou Yichen Wang Xuejuan Wang Shaoxi Niu Xiang Tu Hongliang Shen Zhien Zhou Yinbing Wang Ruiyi Yan Ning Xu Gejun Zhang Hailong Hao Shudong Zhang Ben Liu Bin Yang Baojun Wang Haifeng Wang Haifeng Huang Qian Zhang Baijun Dong Yonghong Li Jianbin Bi Weigang Yan Hongqian Guo Yuanjie Niu Guosheng Yang Ming Liu Qiang Wei Nianzeng Xing 2023UroPrecision2023,1,1:0
4Transient Pulmonary Atelectasis after Ketamine Sedation during Cardiac Catheterization in Spontaneously Breathing Children with Congenital Heart Disease显示文摘Background:Ketamine is applied widely for sedation during cardiac catheterization in spontaneously breathing children with congenital heart disease(CHD).However,a rare and unreported respiratory complication,transient and reversible atelectasis of lungs(TRAL),was identifi ed.Purpose:The study was performed to investigate retrospectively the prevalence and clinical characteristics of TRAL after ketamine sedation in pediatric cardiac catheterization.Methods:Four thousand four hundred and seventy-four sick children were sedated with ketamine,and pediatric cardiac catheterization was carried out under spontaneous breathing.TRAL was detected in 33 children(17 M/16 F,age was 2.1±1.7 years)by retrospective analysis.The clinical and radiographic characteristics were recorded before,during and after TRAL.Results:In pediatric cardiac catheterization,the prevalence of TRAL was 0.74%after ketamine sedation.TRAL occurred in 23 children with cyanotic CHD,and 10 with acyanotic CHD.All TRALs had common clinical and radiographic features:the diffuse opacity of bilateral lungs developed rapidly(identifi ed under X-ray fl uoroscopy),associated with decrease in lung volume,and then the decrease in SpO2(94.2±9.2%vs.59.4±2.2%,P<0.05),and heart rates(143.5±14.3 bpm vs.58.3±9.7 bpm,P<0.05)followed quickly.TRAL was relieved by supportive oxygen in 32 children(23 with face mask,and 9 with endotracheal intubation),and the duration of TRAL was 1.6±0.5 minutes.However,TRAL caused the death of one child.Conclusions:TRAL is a rare and urgent respiratory complication after ketamine sedation,and the mechanism is unclear.Rapid and diffuse opacity of bilateral lungs is the earliest sign of TRAL in pediatric cardiac catheterization,and the immediate supportive oxygen is crucial.Yan Chaowu Xu Zhongying Zhang Gejun Zheng Hong Jin Jinglin Li Shiguo Lv Jianhua Hu Haibo Song Huijun Zhao Shihua 2016Cardiovascular Innovations and Applications2016,,B05:0
