12018 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 2018Science Bulletin2018,63,23:54
2Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing.Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group 2020National Science Review2020,7,12:51

4Epidemiology of fungal infections in China显示文摘与 immunocompromised 主人的增加的数字,真菌的感染的流行病学的特征经历了世界范围的庞大的变化,在中国包括。在这份报纸,我们越过中国在真菌病上考察了存在数据总结可得到的流行病学的侧面。我们发现在中国的表面的真菌的感染的一般发生是稳定的,但是癣 capitis 的发生减少了,传播线路变化了。由对比,侵略真菌的感染的全面发生继续升起了。candidemia 的出现由除 C 以外的 Candida 种类引起了。albicans 和不平常的 Candida 种类最近在中国增加了的包括的一些。曲霉属菌引起的感染也在最近的年里宣传了,特别地与 azole 抵抗的曲霉属菌 fumigatus 的出现。cryptococcosis 的一个增加的趋势在中国被注意了,与 Cryptococcus neoformans var。grubii 圣 5 遗传型作为占优势的病原体孤立。回顾的研究建议了在中国的 Pneumocystis 肺病的流行病学的特征可能类似于在另外的发展中的国家的那些。地方性的真菌的感染例如在东北中国的 sporotrichosis,必须引起研究,诊断,并且处理警戒。当前,在中国的真菌病上的流行病学的数据可变、碎片。因此,关于在中国的真菌的感染的全国流行病学的研究是对改进国家健康的重要需要。Min Chen Yuan Xu Nan Hong Yali Yang Wenzhi Lei Lin Du Jingjun Zhao Xia Lei Lin Xiong Langqi Cai Hui Xu Weihua Pan Wanqing Liao 2018Frontiers of Medicine2018,12,1:49
5Magnetic resonance diffusion tensor imaging following major ozonated autohemotherapy for treatment of acute cerebral infarction显示文摘Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction,but whether major ozonated autohemotherapy affects remote injury remains poorly understood.Here,we assumed that major ozonated autohemotherapy contributes to recovery of clinical function,possibly by reducing remote injury after acute cerebral infarction.Sixty acute cerebral infarction patients aged 30–80 years were equally and randomly allocated to ozone treatment and control groups.Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy(47 mg/L,100 m L ozone) for 10 ± 2 days.Patients in the control group received medical treatment only.National Institutes of Health Stroke Scale score,modified Rankin scale score,and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased,brain function improved,clinical efficiency significantly increased,and no obvious adverse reactions detected in the ozone treatment group compared with the control group.These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury,and additionally,exhibits high safety.Xiao-na Wu Tao Zhang Jun Wang Xiao-yan Liu Zhen-sheng Li Wei Xiang Wei-qing Du Hong-jun Yang Tie-gen Xiong Wen-ting Deng Kai-run Peng Su-yue Pan 2016Neural Regeneration Research2016,11,7:32

8Perspectives on studies on soil carbon stocks and the carbon sequestration potential of China显示文摘Soil carbon stocks and sequestration have been given a lot of attention recently in the study of terrestrial ecosystems and global climate change.This review focuses on the progress made on the estimation of the soil carbon stocks of China,and the characterization of carbon dynamics of croplands with regard to climate change,and addresses issues on the mineralization of soil organic carbon in relation to greenhouse gas emissions.By integrating existing research data,China's total soil organic carbon(SOC) stock is estimated to be 90 Pg and its inorganic carbon(SIC) stock as 60 Pg,with SOC sequestration rates in the range of 20-25 Tg/a for the last two decades.An estimation of the biophysical potential of SOC sequestration has been generally agreed as being 2 Pg over the long term,of which only 1/3 could be attainable using contemporary agricultural technologies in all of China's croplands.Thus,it is critical to enhance SOC sequestration and mitigate climate change to improve agricultural and land use management in China.There have been many instances where SOC accumulation may not induce an increased amount of decomposition under a warming scenario but instead favor improved cropland productivity and ecosystem functioning.Furthermore,unchanged or even decreased net global warming potential(GWP) from croplands with enhanced SOC has been reported by a number of case studies using life cycle analysis.Future studies on soil carbon stocks and the sequestration potential of China are expected to focus on:(1) Carbon stocks and the sequestration capacity of the earths' surface systems at scales ranging from the plot to the watershed and(2) multiple interface processes and the synergies between carbon sequestration and ecosystem productivity and ecosystem functioning at scales from the molecular level to agro-ecosystems.Soil carbon science in China faces new challenges and opportunities to undertake integrated research applicable to many areas.ZHENG JuFeng CHENG Kun PAN GenXing Pete SMITH LI LianQing ZHANG XuHui ZHENG JinWei HAN XiaoJun DU YanLing 2011Chinese Science Bulletin2011,56,35:24
9Experimental and clinical study of influence of high-frequency electric surgical knives on healing of abdominal incision显示文摘瞄准:在腹壁切口愈合上学习高周波的电的外科的刀的影响。方法:240 只白鼠被划分成 10 (0 ) , 10 (2 ) , 10 (5 ) ,并且 10 (8 ) 组和腹部手术的老鼠模型被分别地使用电的外科的刀和普通口针劝诱。然后,他们分别地被给生理盐水和 0.2 mL 的皮下注射在 10 的集中(2 ) 的埃希氏杆菌属关口 i,葡萄球菌 aureus 和绿脓假单胞菌的量的混合, 10 (5 ) 并且 10 (8 ) 。根据动物实验,经历腹部手术(上面的类型 II ) 的 220 个病人随机被分配进跟随三个组之一:电热刀(EK, 93 个盒子) ,电凝法(EC, 55 个盒子) 并且控制(72 个盒子) 。高周波的电的外科的刀习惯于为在 EK 的血壅滞的腹的纸巾和电凝法组织的 dissect。普通口针和电凝法在 EC 组被使用。普通口针和系住的丝缝线在控制被使用。结果:在除了组 10 的所有组(0 ) ,电的外科的刀做的 incisional 创伤的感染率与普通口针比那显著地高。而且,在组有有效差量 10 (2 ) , 10 (5 ) ,并且 10 (8 )(P<0.05 ) ,然而并非(0 )(P>0.05 ) 在组, 10 在 EK 和 EC 之间组织。临床的研究显示出在控制组在 EK,在 EC 的 11 个盒子(16.36%) 和 2 个盒子(2.86%) 在 16 种情况(17.20%) 中愈合的一处推迟的创伤。在 EK 和控制之间的有效差量组织(chi2 = 8.57, P<0.01 ) ,并且在 EC 和控制组之间(chi2 = 5.66, P<0.05 ) 被观察,然而并非在 EK 和 EC 之间(chi2 = 0.017, P>0.05 ) 。结论:高周波的电的刀可以显著地推迟腹壁切口愈合。它的申请应该被最小化以便减少手术后的复杂并发症的可能性。Guang-Wei Ji Yuan-Zhi Wu Xu Wang Hua-Xiong Pan Ping Li Wan-Ying Du Zhi Qi An Huang Li-Wei Zhang Li Zhang Wen Chen Guang-Hua Liu Hui Xu Quan Li Ai-Hua Yuan Xiao-Ping He Guo-Hua Mei 2006World Journal of Gastroenterology2006,12,25:23
10Metastasis-associated protein 1 induces VEGF-C and facilitates lymphangiogenesis in colorectal cancer显示文摘AIM:To study the correlation between high metastasisassociated protein 1(MTA1)expression and lymphangiogenesis in colorectal cancer(CRC)and its role in production of vascular endothelial growth factor-C(VEGF-C). METHODS:Impact of high MTA1 and VEGF-C expression levels on disease progression and lymphovasculardensity(LVD,D2-40-immunolabeled)in 81 cases of human CRC was evaluated by immunohistochemistry. VEGF-C mRNA and protein expressions in human LoVo and HCT116 cell lines were detected by real-time polymerase chain reaction and Western blotting,respectively,with a stable expression vector or siRNA. RESULTS:The elevated MTA1 and VEGF-C expression levels were correlated with lymph node metastasis and Dukes stages(P<0.05).Additionally,high MTA1 expression level was correlated with a large tumor size(P< 0.05).A significant correlation was found between MTA1 and VEGF-C protein expressions in tumor cells(r=0.371, P<0.05).Similar to the VEGF-C expression level,high MTA1 expression level was correlated with high LVD in CRC(P<0.05).Furthermore,over-expression of MTA1 significantly enhanced the VEGF-C mRNA and protein expression levels,whereas siRNAs-knocked down MTA1 decreased the VEGF-C expression level. CONCLUSION:MTA1,as a regulator of tumor-associated lymphangiogenesis,promotes lymphangiogenesis in CRC by mediating the VEGF-C expression.Bin Du Zhen-Yu Yang Xue-Yun Zhon Mao Fang Yong-Rong Yan Guo-Long Qi Yun-Long Pan Xu-Long Zhou 2011World Journal of Gastroenterology2011,17,9:23
11Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21

13Prognostic models for acute liver failure显示文摘BACKGROUND:Acute liver failure (ALF) remains a dramatic and unpredictable disease with high morbidity and mortality. Early and accurate prognostic assessment of patients with ALF is critically important for optimum clinical pathway. DATA SOURCES:Five English-language medical databases,MEDLINE,ScienceDirect,OVID,Springer Link and Wiley Interscience were searched for articles on 'acute liver failure',' prognosis',and related topics. RESULTS:Multi-variable prognostic models including the King’s College Hospital criteria and the model for end-stage liver disease score have been widely used in determination of the prognosis of ALF,but the results are far from satisfactory. Other prognostic indicators including serum Gc-globulin,arterial blood lactate,serum phosphate,arterial blood ammonia,and serum alpha-fetoprotein are promising but await further assessement. CONCLUSIONS:A reliable prognostic model to be developed in the future should not only have predictive value for poor outcome but also help to predict the survival of patients without a liver transplantation. Further studies are necessary to assess the prognostic accuracy of any new models.Du, Wei-Bo Pan, Xiao-Ping Li, Lan-Juan 2010Hepatobiliary & Pancreatic Diseases International2010,9,2:18

16Purification,chemical modification and immunostimulating activity of polysaccharides from Tremella aurantialba fruit bodies显示文摘Ultrafiltration and a series of chromatographic steps were used to isolate and purify polysaccharides from Tremella aurantialba fruit bodies.Three crude fractions(TAP50w,TAP10-50w,and TAP1-10w),five semi-purified fractions(TAPA-TAPE),and one purified fraction(TAPA1) were obtained.A sulfated derivative of TAPA1(TAPA1-s) was prepared by chemical modification.The immunostimulating activity of the polysaccharide fractions in vitro was determined using the mouse spleen lymphocyte proliferation assay.Of the three crude fractions tested,cell prolifera-tion rates were increased most by TAP50w.Furthermore,TAPA1-s was markedly more stimulatory than TAPA1,indicating that sulfonation was an effective way to enhance the immunostimulating activity of polysaccharide.Xiu-ju DU Jing-song ZHANG Yan YANG Qing-jiu TANG Wei JIA Ying-jie PAN 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,6:14
17Removal of copper ions from aqueous solution by calcium alginate immobilized kaolin显示文摘Kaolin has been widely used as an adsorbent to remove heavy metal ions from aqueous solutions.However,the lower heavy metal adsorption capacity of kaolin limits its practical application.A novel environmental friendly material,calcium alginate immobilized kaolin (kaolin/CA),was prepared using a sol-gel method.The effects of contact time,pH,adsorbent dose,and temperature on Cu 2+ adsorption by kaolin/CA were investigated.The Langmuir isotherm was used to describe the experimental adsorption,the maximum Cu 2+ adsorption capacity of the kaolin/CA reached up to 53.63 mg/g.The thermodynamic studies showed that the adsorption reaction was a spontaneous and endothermic process.Yanhui Li Bing Xia Quansheng Zhao Fuqiang Liu Pan Zhang Qiuju Du DechangWang Da Li ZonghuaWang Yanzhi Xia 2011Journal of Environmental Sciences2011,23,3:14
18Effect of Nd on microstructure and mechanical properties of as-extruded Mg-Y-Zr-Nd alloy显示文摘The microstructure and mechanical properties of Mg-Y-Zr-x Nd alloys with 0–2.63 wt% Nd were investigated using optical microscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction and tensile testing test. Results indicated that more Mg_(24)Y_5 particles and Mg_(14)Nd_2Y(β) phases were dispersed in the matrix when Nd content increased from 0 wt% to 2.63 wt% in the extruded alloys.Consequently, the nucleation of dynamic recrystallization and the volume fraction of recrystallized grains were promoted obviously. The average grain size can be refined in the range of 4.6–1.3 μm after the addition of 2.63 wt% Nd. The tensile strength of extruded alloys increased with increasing Nd content, and elongation exhibited an opposite change tendency. The extruded alloy sheet with 1.01 wt% Nd demonstrates optimal combination of strength and plasticity, i.e., the ultimate tensile strength, yield strength,and elongation were 273 MPa, 214 MPa, and 24.2%, respectively. Variations in mechanical properties are discussed on the basis of microstructure observations.Xiaoyang Xu Xianhua Chen Weiwei Du Yuxiao Geng Fusheng Pan 2017Journal of Materials Science & Technology2017,33,9:14
19Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits.Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang 2022National Science Review2022,9,1:13
