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
2Single-incision vs three-port laparoscopic cholecystectomy:Prospective randomized study显示文摘AIM:To compare the clinical outcome of single-inci-sion laparoscopic cholecystectomy(SILC)with threeport laparoscopic cholecystectomy(TPLC). METHODS:Between 2009 and 2011,one hundred and two patients with symptomatic benign gallbladder diseases were randomized to SILC(n=49)or TPLC (n=53).The primary end point was post operative pain score(at 6 h and 7 d).Secondary end points were blood loss,operation duration,overall complications,postoperative analgesic requirements,length of hospital stay,cosmetic result and total cost.Surgical techniques were standardized and all operations were performed by one experienced surgeon,who had performed more than 500 laparoscopic cholecystectomies. RESULTS:One patient in the SILC group required conversion to two-port LC.There were no open conversions or major complications in either treatment groups.There were no differences in terms of esti-mated blood loss(mean±SD,14±6.0 mL vs 15±4.0 mL),operation duration(mean±SD,41.8±17.0 min vs 38.5±22.0 min),port-site complications(contusion at incision:5 cases vs 4 cases and hematoma at inci- sion:2 cases vs 1 case),total cost(mean±SD,12 075 ±1047 RMB vs 11 982±1153 RMB)and hospital stay (mean±SD,1.0±0.5 d vs 1.0±0.2 d),respectively. TPLC had a significantly worse visual analogue pain score at 8 h after surgery(mean±SD,3.5±1.6 vs 2.0 ±1.5),however,the scores were similar on day 7(mean ±SD,2.5±1.4 vs 2.0±1.3).Cosmetic satisfaction, as determined by a survey at 2 mo follow-up favored SILC(mean±SD,8±0.4 vs 6±0.2). CONCLUSION:SILC is a safe and feasible approach in selected patients.The main advantages are a better cosmetic result and less pain.Ming-Xin Pan Ze-Sheng Jiang Yuan Cheng Xiao-Ping Xu Zhi Zhang Jia-Sheng Qin Guo-Lin He Ting-Cheng Xu Chen-Jie Zhou Hai-Yan Liu Yi Gao 2013World Journal of Gastroenterology2013,19,3:24

4A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding.Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu 2020Molecular Plant2020,13,9:14
5Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14
6Effects of biochar-based fertilizers on nutrient leaching in a tobacco-planting soil显示文摘Biochar is a soil amendment for increasing soil quality and decreasing nutrient leaching. However, there is little information on the impact of biochar-based fertilizer(BF) on soil nutrient leaching in agricultural soils. We conducted a soil column leaching experiment to study the effects of BF on the leaching of total nitrogen(TN), total phosphorus, and total potassium(TK) in tobacco soils. The distribution characteristics of NH_4^+-N, available P, and available K in soil profiles were analyzed after the application of BF. Biochar was prepared by pyrolysis of fluecured tobacco stems. It was applied at four levels, 0%, 3%,9%, and 15%(w/w), respectively, to the compound fertilizer. Compared with the control, the leaching loss of soil TN decreased by 8.36%, 6.72%, and 6.45%, and the loss of soil TK decreased by 9.18%, 9.31% and 11.82% in the 3%,9%, and 15% BF treatments, respectively. However, BF had no significant effect on the P leaching due to the low movement of P in the soil profile. In addition, the BF addition increased the immobilization of NH_4^+-N, available P, and available K in the soil profile. These results indicate that addition of BF to a tobacco-planting soil reduced nutrient leaching, and suggest that BF could be an effective method of applying biochar to agriculture fields.Yunlong Li Jianzhong Cheng Xinqing Lee Yi Chen Weichang Gao Wenjie Pan Yuan Tang 2019Acta Geochimica2019,38,1:13
7Hybrid bioartificial liver support in cynomolgus monkeys with D-galactosamine-induced acute liver failure显示文摘AIM:To evaluate a hybrid bioartificial liver support system(HBALSS)in cynomolgus monkeys with acute liver failure.METHODS:To establish a model of acute liver failure,0.3 g/kg of D-galactosamine was injected intravenously into cynomolgus monkeys.Chinese human liver cells were introduced into a perfusion bioreactor to carry out hybrid bioartificial liver support treatment.Forty-eight hours after the injection,one group of cynomolgus monkeys received HBALSS care,and a second experimental group received no treatment.Clinical manifestations of all animals,survival time,liver and kidney functions and serum biochemistry changes were recorded.Simultaneous detection of the number,viability and function of hepatocytes in the hybrid bioartificial liver were also performed.RESULTS:Forty-eight hours after the injection of D-galactosamine,serum biochemistry levels were significantly increased,whereas albumin levels and the Fischer index were significantly reduced compared to baseline(all P s<0.05).Of the ten monkeys in the HBALSS treatment group,five survived,with an average duration of survival of 128±3 h.All cynomolgus monkeys in the control group died,with a duration of survival of112±2 h.Survival time was significantly longer with HBALSS treatment(P<0.05).Moreover,the number,viability and function of hepatocytes were maintained at a high level with HBALSS.CONCLUSION:The novel hybrid bioartificial liver plays a significant role in liver support by significantly reducing serum biochemistry levels and extending animal survival time.Zhi Zhang Yi-Chao Zhao Yuan Cheng Guo-Deng Jian Ming-Xin Pan Yi Gao 2014World Journal of Gastroenterology2014,20,46:12
8Learning curve of transumbilical suture-suspension single-incision laparoscopic cholecystectomy显示文摘AIM: To investigate the learning curve of transumbilical suture-suspension single-incision laparoscopic cholecystectomy (SILC). METHODS: The clinical data of 180 consecutive transumbilical suture-suspension SILCs performed by a team in our department during the period from August 2009 to March 2011 were retrospectively analyzed. Patients were divided into nine groups according to operation dates, and each group included 20 patients operated on consecutively in each time period. The surgical outcome was assessed by comparing operation time, blood loss during operation, and complications between groups in order to evaluate the improvement in technique.RESULTS: A total of 180 SILCs were successfully performed by five doctors. The average operation time was 53.58 ± 30.08 min (range: 20.00-160.00 min) and average blood loss was 12.70 ± 11.60 mL (range: 0.00-100.00 mL). None of the patients were converted to laparotomy or multi-port laparoscopic cholecystectomy. There were no major complications such as hemorrhage or biliary system injury during surgery. Eight postoperative complications occurred mainly in the first three groups (n = 6), and included ecchymosis around the umbilical incision (n = 7) which resolved without special treatment, and one case of delayed bile leakage in group 8, which was treated by ultrasound-guided puncture and drainage. There were no differences in intraoperative blood loss, postoperative complications and length of postoperative hospital stay among the groups. Bonferroni's test showed that the operation time in group 1 was significantly longer than that in the other groups (F = 7.257, P = 0.000). The majority of patients in each group were discharged within 2 d, with an average postoperative hospital stay of 1.9 ± 1.2 d. CONCLUSION: Following scientific principles and standard procedures, a team experienced in multi-port laparoscopic cholecystectomy can master the technique of SILC after 20 cases.Ming-Xin Pan Zhi-Wei Liang Yuan Cheng Ze-Sheng Jiang Xiao-Ping Xu Kang-Hua Wang Hai-Yan Liu Yi Gao 2013World Journal of Gastroenterology2013,19,29:11

10Laparoendoscopic single-site cholecystectomy vs three-port laparoscopic cholecystectomy: A large-scale retrospective study显示文摘AIM: To perform a large-scale retrospective comparison of laparoendoscopic single-site cholecystectomy (LESSC) and three-port laparoscopic cholecystectomy (TPLC) in a single institution. METHODS: Data were collected from 366 patients undergoing LESSC between January 2005 and July 2008 and were compared with the data from 355 patients undergoing TPLC between August 2008 and November 2011 in our department. Patients with body mass index greater than 35 kg/m2 , a history of major upper abdominal surgery, signs of acute cholecystitis, such as fever, right upper quadrant tenderness with or without Murphy's sign, elevated white blood cell count, imaging findings suggestive of pericholecystic fluid, gallbladder wall thickening > 4 mm, and gallstones > 3 cm, were excluded to avoid bias. RESULTS: Altogether, 298 LESSC and 315 TPLC patients met the inclusion criteria. The groups were well matched with regard to demographic data. There were no significant differences in terms of postoperative complications (contusion: 19 vs 25 and hematoma at incision: 11 vs 19), hospital stay (mean ± SD, 1.4 ± 0.2 d vs 1.4 ± 0.7 d) and visual analogue pain score (mean ± SD, 8 h after surgery: 2.3 ± 1.4 vs 2.3 ± 1.3 and at day 1: 1.2 ± 0.4 vs 1.3 ± 1.2) between the LESSC and TPLC patients. Four patients required the addition of extra ports and 2 patients were converted to open surgery in the LESSC group, which was not significantly different when compared with TPLC patients converted to laparotomy (2 vs 2). LESSC resulted in a longer operating time (mean ± SD, 54.8 ± 11.0 min vs 33.5 ± 9.0 min), a higher incidence of intraoperative gallbladder perforation (56 vs 6) and higher operating cost (mean ± SD, 1933.7 ± 64.4 USD vs 1874.7 ± 46.2 USD) than TPLC. No significant differences in operating time (mean ± SD, 34.3 ± 6.0 min vs 32.7 ± 8.7 min) and total cost (mean ± SD, 1881.3 ± 32.8 USD vs 1876.2 ± 33.4 USD) were found when the last 100 cases in the two groups were compared. A correlation was observed between reduced operating time of LESSC and increased experience (Spearman rank correlation coefficient, -0.28). More patients in the LESSC group expressed satisfaction with the cosmetic result (98% vs 85%). CONCLUSION: LESSC is a safe and feasible procedure in selected patients with benign gallbladder diseases, with the significant advantage of cosmesis.Yuan Cheng Ze-Sheng Jiang Xiao-Ping Xu Zhi Zhang Ting-Cheng Xu Chen-Jie Zhou Jia-Sheng Qin Guo-lin He Yi Gao Ming-Xin Pan 2013World Journal of Gastroenterology2013,19,26:8
11Evaluation of Vaporized Hydrogen Peroxide Fumigation as a Method for the Bio-decontamination of the High Efficiency Particulate Air Filter Unit显示文摘Objective To evaluate the performance of vaporized hydrogen peroxide (VHP) for the bio-decontamination of the high efficiency particulate air (HEPA) filter unit. Methods Self-made or commercially available bioindicators were placed at designated locations in the HEPA filter unit under VHP fumigation. The spores on coupons were then extracted by 0.5 h submergence in eluent followed by 200-time violent knocks. Results Due to the presence of HEPA filter in the box, spore recovery from coupons placed at the bottom of the filter downstream was significantly higher than that from coupons placed at the other locations. The gap of decontamination efficiency between the top and the bottom of the filter downstream became narrower with the exposure time extended. The decontamination efficiency of the bottom of the filter downstream only improved gently with the injection rate of H2O2 increased and the decontamination efficiency decreased instead when the injection rate exceeded 2.5 g/min. The commercially available bioindicators were competent to indicate the disinfection efficiency of VHP for the HEPA filter unit. Conclusion The HEPA filter unit is more difficult than common enclosure to decontaminate using VHP fumigation. Complete decontamination can be achieved by extending fumigation time. VHP fumigation can be applied for in-situ biodecontamination of the HEPA filter unit as an alternative method to formaldehyde fumigation.JIA Hai Quan LI Yan Ju SUN Bei ZHAO Si Qing YI Ying ZHAO Ming ZHANG Zong Xing PAN Xin QI Jian Cheng 2013Biomedical and Environmental Sciences2013,26,2:8

14Chemotherapy response evaluation in a mouse model of gastric cancer using intravoxel incoherent motion diffusionweighted MRI and histopathology显示文摘AIM To determine the role of intravoxel incoherent motion(IVIM) diffusion-weighted(DW) magnetic resonance imaging(MRI) using a bi-exponential model in chemotherapy response evaluation in a gastric cancer mouse model.METHODS Mice bearing MKN-45 human gastric adenocarcinoma xenografts were divided into four treated groups(TG1, 2, 3 and 4, n = 5 in each group) which received Fluorouracil and Calcium Folinate and a control group(CG, n = 7). DW-MRI scans with 14 b-values(0-1500 s/mm2) were performed before and after treatment on days 3, 7, 14 and 21. Fast diffusion component(presumably pseudo-perfusion) parameters including the fast diffusion coefficient(D*) and fraction volume(f p), slow diffusion coefficient(D) and the conventional apparent diffusion coefficients(ADC) were calculated by fitting the IVIM model to the measured DW signals. The median changes from the baseline to each posttreatment time point for each measurement(ΔADC, ΔD* and Δf p) were calculated. The differences in the median changes between the two groups were compared using the mixed linear regression model by the restricted maximum likelihood method shown as z values. Histopathological analyses including Ki-67, CD31, TUNEL and H&E were conducted in conjunction with the MRI scans. The median percentage changes were compared with the histopathological analyses between the pre-and post-treatment for each measurement.RESULTS Compared with the control group, D* in the treated group decreased significantly(ΔD*treated% =-30%,-34% and-20%, with z =-5.40,-4.18 and-1.95. P = 0.0001, 0.0001 and 0.0244) and f p increased significantly(Δfptreated% = 93%, 113% and 181%, with z = 4.63, 5.52, and 2.12, P = 0.001, 0.0001 and 0.0336) on day 3, 7 and 14, respectively. Increases in ADC in the treated group were higher than those in the control group on days 3 and 14(z = 2.44 and 2.40, P = 0.0147 and P = 0.0164). CONCLUSION Fast diffusion measurements derived from the biexponential IVIM model may be more sensitive imaging biomarkers than ADC to assess chemotherapy response in gastric adenocarcinoma.Jin Cheng Yi Wang Chun-Fang Zhang He Wang Wei-Zhen Wu Feng Pan Nan Hong Jie Deng 2017World Journal of Gastroenterology2017,23,11:6
15Artificial liver support in pigs with acetaminophen-induced acute liver failure显示文摘AIM To establish a reversible porcine model of acute liver failure(ALF) and treat it with an artificial liver system. METHODS Sixteen pigs weighing 30-35 kg were chosen and administered with acetaminophen(APAP) to induce ALF. ALF pigs were then randomly assigned to either an experimental group(n = 11), in which a treatment procedure was performed, or a control group(n = 5). Treatment was started 20 h after APAP administration and continued for 8 h. Clinical manifestations of all animals, including liver and kidney functions, serum biochemical parameters and survival times were analyzed. RESULTS Twenty hours after APAP administration, the levels of serum aspartate aminotransferase, total bilirubin, creatinine and ammonia were significantly increased, while albumin levels were decreased(P < 0.05). Prothrombin time was found to be extended with progression of ALF. After continuous treatment for 8 h(at 28 h), aspartate aminotransferase, total bilirubin, creatinine, and ammonia showed a decrease in comparison with the control group(P < 0.05). A cross-section of livers revealed signs of vacuolar degeneration, nuclear fragmentation and dissolution.Concerning survival, porcine models in the treatment group survived for longer times with artificial liver system treatment(P < 0.05). CONCLUSION This model is reproducible and allows for quantitative evaluation of new liver systems, such as a bioartificial liver. The artificial liver system(ZHj-3) is safe and effective for the APAP-induced porcine ALF model.Guo-Lin He Lei Feng Lei Cai Chen-jie Zhou Yuan Cheng Ze-Sheng jiang Ming-xin Pan Yi Gao 2017World Journal of Gastroenterology2017,23,18:5
16Antipyretic Effects of Liposoluble Fractions of Viola yedoensis显示文摘Objective To clarify the antipyretic effect of the Chinese materia medica, Violae Herba(Viola yedoensis), and its active fractions by examining the effects of V. yedoensis extracts with differing polarities on body temperature, total white blood cell(WBC) count, WBC differential count, and total serum complement of rabbits with lipopolysaccharide(LPS)-induced fever. Methods The rabbits were treated with water and ethanolic extracts of V. yedoensis, as well as petroleum ether, ethyl acetate, and n-butanol fractions of the ethanolic extract at low-, mid- and high- doses. The LPS was injected via the ear vein of rabbits in model and treatment groups 30 min post-gavage. Their body temperature was measured at 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0 h after the LPS challenge to calculate the temperature changes and thermal response index. After the last temperature measurement, blood samples were collected to determine the blood cell counts and total serum complement(CH50) level. Results Compared with the model group, body temperature was significantly lower in the low-dose ethanolic extract group, low- and mid-dose petroleum ether fraction groups, and all three ethyl acetate fraction groups. Serum CH50 levels were lower in all treatment groups, except the ethanolic extract groups, than that in the model group, with no significant difference. V. yedoensis had no significant effect on the blood cells of febrile rabbits challenged with LPS for 6 h. Conclusion The antipyretic effects of V. yedoensis are strong, and its active fractions are the petroleum ether and ethyl acetate fractions of ethanolic extract.Ying-yi Pan Zhe-ping Song Guo-fu Zhu Yuan-zhang Zhu Yi Lu Wen-long Li Jie Cao Zhi-hong Cheng 2015Chinese Herbal Medicines2015,7,1:4

Both methods are superior to the conventional procedure in cosmetic and pain scores.Guo-Lin He Ze-Sheng Jiang Yuan Cheng Qing-Bo Lai Chen-Jie Zhou Hai-Yan Liu Yi Gao Ming-Xin Pan Zhi-Xiang Jian 2015World Journal of Gastrointestinal Endoscopy2015,7,5:4
18First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region.Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu 2021Science China(Physics,Mechanics & Astronomy)2021,64,8:3
19First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.).

20SC-IrO_2 NR-carbon hybrid:A catalyst with high electrochemical stability for oxygen reduction显示文摘The enhanced electrochemical stability of the synthesized hybrid catalyst has been demonstrated by the introduction of the synergistic effect between carbon powder additive and the prepared catalyst.Single crystal IrO 2 nanorod (SC-IrO 2 NR) catalyst was prepared by a sol-gel method.The structure and performance of the catalyst sample were characterized by X-ray diffraction spectroscopy (XRD),scanning electron microscope (SEM),transmission electron microscope (TEM),rotating disk electrode (RDE) and cyclic voltammetry (CV) measurements.XRD patterns and TEM images indicate that the catalyst sample has a rutile IrO 2 single crystal nanorod structure.The onset potential for oxygen reduction reaction (ORR) of the SC-IrO 2 NR-carbon hybrid catalyst specimen is 0.75 V (vs.RHE) in RDE measurement.CV and RDE test results show that the SC-IrO 2 NR-carbon hybrid catalyst has a better electrochemical stability in comparison with the commercial Pt/C catalyst,with attenuation ratios of 17.67% and 44.60% for the SC-IrO 2 NR-carbon hybrid catalyst and the commercial Pt/C catalyst after 1500 cycles,respectively.Therefore,in terms of stability,the SC-IrO 2 NR-carbon hybrid catalyst has a promising potential in the application of the proton exchange membrane fuel cell.WANG GuangJin CHENG Feng YU Yi LIANG Cong XU Tian PAN Mu 2013Science China Chemistry2013,56,1:3
