| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Analysis of negative DSA findings in patients with acute nonvariceal gastrointestinal bleeding: A retrospective study of 133 patients显示文摘Purpose: To analyze causes of acute nonvariceal gastrointestinal bleeding(GIB) with negative digital subtraction angiography(DSA) results.Materials and methods: The clinical and follow-up data of 133 patients-recruited between February 2008 and November 2016-with acute nonvariceal GIB and negative DSA results were included in this study. DSA results,diagnoses, and clinical outcomes were recorded.Results: The DSA results were negative in all 133 patients. Of the total, 55 patients(41.4%) chose to undergo surgery and 78(58.6%) opted for conservative treatment. Within 30 days, there was no significant difference in the rebleeding or mortality rates between the two groups(P <.05). Of all 133 patients, 76(57.1%) had upper GIB and 57(42.9%) had lower GIB;within 30 days, the rebleeding rate in the upper GIB group(44.7%, 34/76) was significantly higher than that in the lower GIB group(26.3%, 15/57). There was no significant statistical difference(P <.05) within 30 days in the mortality rates between the two groups.Among patients with upper GIB, 26(34.2%, 26/76) opted to undergo surgery and 50(65.8%, 50/76) chose conservative treatment;within 30 days, the rebleeding rate in the group that chose surgery(61.5%, 16/26) was higher than that in the conservative treatment group(36%, 18/50). There was no significant difference(P <.05)within 30 days in the mortality rate between the two groups.Among the patients with lower GIB, 29(50.9%, 29/57) chose to undergo surgery and 28(49.1%, 28/57) opted for conservative treatment. Within 30 days, the rebleeding rate in the surgery group(13.8%, 4/29) was lower than that in conservative treatment group(39.3%, 11/28). There was no significant difference(P <.05) within 30 days in the mortality rate between the two groups.Sixteen patients underwent prophylactic arterial embolization;in 6 of these, bleeding was stopped for 30 days.DSA was then repeated in these 16 patients after a median interval of 1 day, and a positive bleeding site was found in 9 of the 16. Causes of bleeding were found in 111 patients by surgery or endoscopy, whereas the causes remained unknown in 22 patients.Conclusions: Upper GIB with negative DSA results was stopped by conservative treatment, whereas lower GIB required surgery to detect the culprit bleeding site. Rare causes of GIB should be considered and appropriate management selected in a timely manner in order to detect unusual causes. | Tianhe Ye Lian Yang Qi Wang Jiacheng Liu Chen Zhou Chuansheng Zheng Bin Xiong | 2019 | Journal of Interventional Medicine2019，2，1： | 3 |

| 5 | Preparation of Scratch-Resistant Nano-Porous Silica Films Derived by Sol-Gel Process and Their Anti-reflective Properties显示文摘Structural strengthening of the nano porous silica films has been reported. The films were prepared with a base/acid two-step catalyzed TEOS-based sol-gel processing and dip-coating, and then baked in the mixed gas of ammonia and water vapor. The silica films were characterized with TEM, AFM, FTIR, spectrophotometer, ellipsometer, and abrasion test, respectively. The experimental results have shown that the films have a nanostructure with a low refractive index and can form an excellent scratch-resistant broadband anti-reflectance. The two-step catalysis noticeably strengthens the films, and the mixed gas treatment further improves mechanical strength of the silica network. Finally the strengthening mechanism has been discussed. | Guangming WU, Jun SHEN, Tianhe YANG, Bin ZHOU and Jue WANGPohl Institute of Solid State Physics, Tongji University, Shanghai 200092, China | 2003 | Journal of Materials Science & Technology2003，19，4： | 0 |
| 6 | Synthesis of MgO-Modified Mesoporous Silica and Its Adsorption Performance toward CO_2显示文摘The mesoporous silica modified with magnesium oxide(MgO) was synthesized by one step method and impregnating method,respectively.The samples were characterized by small angle X-Ray diffraction(XRD),N_2 adsorption-desorption and transmission electron microscopy(TEM),and the carbon dioxide adsorption capacity was analyzed by thermal gravimetric analysis(TGA).Compared with the original mesoporous silica(20.7 mg/g),the CO_2 adsorption capacity of MgO-modified mesoporous silica processed by one step method increases to 32.9 mg/g.Although its surface area greatly decreases compared with that of the original mesoporous silica,the MgO-modified mesoporous silica prepared by impregnating reaches an adsorptive value of 31.1 mg/g because the number of basic sites increases on the surface of the mesoporous silica. | LIU Qiming MA Juanjuan ZHOU Yuan WANG Tianhe | 2014 | Wuhan University Journal of Natural Sciences2014，19，2： | 0 |
| 7 | 母本—合子基因组控制转换的两个阶段与父母亲本对基因组贡献的两个时相显示文摘文章简介无论动物与植物,其早期胚胎发生过程中都有一个母本基因组控制到合子基因组控制的转换过程(MZT)。有关研究表明,动物胚胎发育的早期阶段是母本控制的,直到胚胎发育至多细胞囊胚时才逐渐转换至合子基因组控制。这一转换意味着精卵结合后产生的合子基因组被激活,新的发育程序开始指导胚胎发育过程。 | 赵鹏 Xuemei Zhou Kun Shen Zhenzhen Liu Tianhe Cheng Danni Liu Yanbing Cheng Xiongbo Peng 孙蒙祥 | 2020 | 科学新闻2020，，2： | 0 |
