| 2 | Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans. | Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang | 2020 | Chinese Medical Journal2020,,9: | 99 |
| 3 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021,64,1: | 122 |
| 4 | Effect of early enteral nutrition on postoperative nutritional status and immune function in elderly patients with esophageal cancer or cardiac cancer显示文摘Objective: To explore the effect of early enteral nutrition (EN) on postoperative nutritional status, intestinal permeability, and immune function in elderly patients with esophageal cancer or cardiac cancer. Methods: A total of 96 patients with esophageal cancer or cardiac cancer who underwent surgical treatment in our hospital from June 2007 to December 2010 were enrolled in this study. They were divided into EN group (n=50) and parenteral nutrition (PN) group (n=46) based on the nutrition support modes. The body weight, time to first flatus/defecation, average hospital stay, complications and mortality after the surgery as well as the liver function indicators were recorded and analyzed. Peripheral blood samples were collected on the days 1, 4 and 7 after surgery. The plasma diamine oxidase (DAO) activity and D-lactate level were determined to assess the intestinal permeability. The plasma endotoxin levels were determined using dynamic turbidimetric assay to assess the protective effect of EN on intestinal mucosal barrier. The postoperative blood levels of inflammatory cytokines and immunoglobulins were determined using enzyme- linked immunosorbent assay (ELISA). Results: After the surgery, the time to first flatus/defecation, average hospital stay, and complications were significantly less in the EN group than those in the PN group (P<0.05), whereas the EN group had significantly higher albumin levels than the PN group (P<0.05). On the 7th postoperative day, the DAO activity, D-lactate level and endotoxin contents were significantly lower in the EN group than those in the PN group (all P<0.05). In addition, the EN group had significantly higher IgA, IgG, IgM, and CD4 levels than the PN group (P<0.05) but significantly lower IL-2, IL-6, and TNF-α levels (P<0.05). Conclusions: In elderly patients with esophageal cancer or cardiac cancer, early EN after surgery can effectively improve the nutritional status, protect intestinal mucosal barrier (by reducing plasma endoxins), and enhance the immune | Guiping Yu Guoqiang Chen Bin Huang Wenlong Shao Guangqiao Zeng | 2013 | Chinese Journal of Cancer Research2013,25,3: | 67 |
| 5 | 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 |

| 7 | Crustal deformation on the Chinese mainland during 1998—2004 based on GPS data显示文摘This study focuses on resolving moderate amounts of crustal motion at the continental scale based on a large volume of global positioning system(GPS) data during 1998e2014. A state-of-the-art GPS processing strategy was used to resolve position time series and velocities from carrier beat phases for all available data. Position time series were closely analyzed to estimate linear constant, coseismic displacements, postseismic motions, and other parameters. We present coseismic offsets inferred from the GPS data for the 2010 Yushu and 2014 Yutian earthquakes, and also illustrate transient postseismic motions following the 2001 Kokoxili, 2008 Wenchuan, and 2011 Tohoku-Oki earthquakes. Since not all GPS position time series dominated by postseismic motions can be modeled and corrected reasonably, we present contemporary horizontal velocities from 2009 to 2014 for campaign stations and from 1998 to 2014 for continuous stations, irrespective of postseismic deformations. Our study concludes that we need to accumulate observations over a greater duration and apply accurate postseismic modeling to correct for transient displacement in order to resolve reasonable interseismic velocity. | Zhao Bin Huang Yong Zhang Caihong Wang Wei Tan Kai Du Rinlin | 2015 | Geodesy and Geodynamics2015,6,1: | 50 |
| 8 | Primary hepatic neuroendocrine carcinoma:clinical analysis of 11 cases显示文摘BACKGROUND:Primary hepatic neuroendocrine carcinoma (PHNEC) is extremely rare,and fewer than 300 cases have been reported in the English/Chinese-language literature,therefore it is difficult to make a proper diagnosis and determine a therapeutic approach.METHODS:Eleven PHNEC patients were admitted to our hospital between January 1996 and May 2008.Laboratory examination,digestive endoscopy,B-ultrasonography,CT,MRI,or PET-CT were performed on the patients for preoperative diagnosis.All patients received liver resection.Some patients received transcatheter arterial chemoembolization (TACE),percutaneous ethanol injection treatment (PEIT),or octreotide injection when a recurrence was found.The patients' clinical data were recorded and all patients were followed up.RESULTS:The patients were confirmed pathologically as having PHNEC.Their median follow-up time was 33 months (12-107 months).All patients survived,and the longest postoperative survival time was 107 months,the longest diseasefree survival time was 98 months,the 1-year survival rate was 100%,and the 1-year recurrence rate was 45.5% (5/11).CONCLUSIONS:Since PHNEC is easy to confuse with hepatocellular carcinoma,careful screening of symptoms is needed to avoid misdiagnosis.Resection is the first choice of treatment for PHNEC and provides the most favorable outcomes including long-term survival.Other treatment such as TACE and PEIT can be considered as well,especially when a tumor recurs. | Huang, Yang-Qing Xu, Feng Yang, Jia-Mei Huang, Bin | 2010 | Hepatobiliary & Pancreatic Diseases International2010,9,1: | 36 |
| 9 | Detection of nighttime sea fog/stratus over the Huang-hai Sea using MTSAT-1R IR data显示文摘A dual channel difference (DCD) method is applied to detect nighttime sea fog/stratus over the Huanghai Sea using the infrared (IR) data of shortwave (3.5–4.0 μm) and longwave (10.3–11.3 μm) channels from the Multi-functional Transport Satellite (MTSAT)-1R, i.e., shortwave minus longwave brightness temperature difference (SLTD). Twenty-four sea fog events over the Huanghai Sea during March to July of 2006 and 2007 are chosen to determine a suitable value of SLTD for nighttime sea fog/stratus detection, and it is found that the value of –5.5––2.5°C can be taken as a criterion. Two case examples of sea fog events are especially demonstrated in detail utilizing the criterion, and the results show that the derived sea fog/stratus coverage is quite reasonable. This coverage information is very helpful to analyze the formation and evolution of sea fog/stratus during night and can provide sea fog researchers with observational evidences for model results verification. However, more efforts are needed to further obtain vertical extent information of sea fog/stratus and attempt to discriminate between sea fog and stratus. | GAO Shanhong WU Wei ZHU Leilei FU Gang HUANG Bin | 2009 | Acta Oceanologica Sinica2009,28,2: | 36 |

| 11 | 42,573 cases of hepatectomy in China: a multicenter retrospective investigation显示文摘Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival. | Binhao Zhang Bixiang Zhang Zhiwei Zhang Zhiyong Huang Yifa Chen Minshan Chen Ping Bie Baogang Peng Liqun Wu Zhiming Wang Bo Li Jia Fan Lunxiu Qin Ping Chen Jingfeng Liu Zhe Tang Jun Niu Xinmin Yin Deyu Li Songqing He Bin Jiang Yilei Mao Weiping Zhou Xiaoping Chen | 2018 | Science China(Life Sciences)2018,61,6: | 39 |

| 13 | Laparoscopic and open splenectomy and azygoportal disconnection for portal hypertension显示文摘AIM: To compare the outcomes of laparoscopic and open splenectomy and azygoportal devascularization for portal hypertension.METHODS: From June 2006 to March 2009, laparo-scopic splenectomy and azygoportal disconnection (LSD) were performed on 28 patients with cirrhosis, bleeding due to portal hypertension, and secondary hypersplenism. Success was achieved in 26 patients. Demographic, intraoperative, and postoperative variables of the patients were compared.RESULTS: Success of laparoscopic splenectomy and azygoportal disconnection was achieved in all but two patients (7.14%) who required open splenectomy and azygoportal devascularization (OSD). The operation time was signif icantly longer in patients undergoing LSD than in those undergoing OSD (235 ± 36 min vs 178 ± 47 min, P < 0.05). The estimated intraoperative blood loss was much more in patients receiving OSD than in those receiving LSD (420 ± 50 mL vs 200 ± 30 mL, P < 0.01). The proportion of patients undergoing laparoscopic and open splenectomy and azygoportal disconnection who received transfusion of packed red blood cells during or after the operation was 23.08% and 38.46%, respectively (P < 0.05). The time of f irst oral intake was faster in patients after LSD than in those after OSD (1.5 ± 0.7 d vs 3.5 ± 1.6 d, P < 0.05). The hospital stay of patients after LSD was shorter than that of patients after OSD (6.5 ± 2.3 d vs 11.7 ± 4.5 d, P < 0.05). The pain requiring medication was less severe in patients after LSD than in those after OSD (7.69% vs 73.08%, P < 0.001). The overall complication rate was lower in patients after LSD than in those after OSD (19.23% vs 42.31%, P < 0.05).CONCLUSION: Laparoscopic splenectomy and azygoportal disconnection are the feasible, effective, and safe surgical procedure, and are advantageous over minimally invasive surgery for bleeding portal hypertension and hypersplenism. | Xiao-Zhong Jiang Shao-Yong Zhao Hong Luo Bin Huang Chang-Song Wang Lei Chen You-Jiang Tao | 2009 | World Journal of Gastroenterology2009,15,27: | 32 |
| 14 | Multi-objective optimization of a mixed-flow pump impeller using modified NSGA-II algorithm显示文摘In order to maintain a uniform distribution of pareto-front solutions, a modified NSGA-II algorithm coupled with a dynamic crowding distance(DCD) method is proposed for the multi-objective optimization of a mixed-flow pump impeller. With the pump meridional section fixed, ten variables along the shroud and hub are selected to control the blade load by using a three-dimensional inverse design method. Hydraulic efficiency, along with impeller head, is applied as an optimization objective; and a radial basis neural network(RBNN) is adopted to approximate the objective function with 82 training samples. Local sensitivity analysis shows that decision variables have different impacts on the optimization objectives. Instead of randomly selecting one solution to implement, a technique for ordering preferences by similarity to ideal solution(TOPSIS) is introduced to select the best compromise solution(BCS) from pareto-front sets. The proposed method is applied to optimize the baseline model, i.e. a mixed- flow waterjet pump whose specific speed is 508 min?1?m3s?1?m. The performance of the waterjet pump was experimentally tested. Compared with the baseline model, the optimized impeller has a better hydraulic efficiency of 92% as well as a higher impeller head at the design operation point. Furthermore, the off-design performance is improved with a wider highefficiency operation range. After optimization, velocity gradients on the suction surface are smoother and flow separations are eliminated at the blade inlet part. Thus, the authors believe the proposed method is helpful for optimizing the mixed-flow pumps. | HUANG RenFang LUO XianWu JI Bin WANG Peng YU An ZHAI ZhiHong ZHOU JiaJian | 2015 | Science China(Technological Sciences)2015,58,12: | 32 |

| 16 | Robust quantum secure direct communication with a quantum one-time pad over a collective-noise channel显示文摘We present two robust quantum secure direct communication (QSDC) schemes with a quantum one-time pad over a collective-noise channel. Each logical qubit is made up of two physical qubits and it is invariant over a collective-noise channel. The two photons in each logical qubit can be produced with a practically entangled source, i.e., a parametric down-conversion source with a beta barium borate crystal and a pump pulse of ultraviolet light. The information is encoded on each logical qubit with two logical unitary operations, which will not destroy the antinoise feather of the quantum systems. The receiver Bob can read out the sender's message directly with two single-photon measurements on each logical qubit, instead of Bell-state measurements, which will make these protocols more convenient in a practical application. With current technology, our two robust QSDC schemes are feasible and may be optimal ones. | GU Bin ZHANG ChengYi CHENG GuoSheng HUANG YuGai | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,5: | 28 |
| 17 | Efficacy and safety of Xinfeng capsule in patients with rheumatoid arthritis:a multi-center parallel-group double-blind randomized controlled trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of Xinfeng capsule in patients suffering rheumatoid arthritis(RA).METHODS:A multi-center parallel-group designed,double-blind,randomized,controlled trial was conducted.Totally 304 RA patients were assigned to two groups:one group was administered Xinfeng capsule(XFC) plus the placebo of leflunomide and the other given leflunomide(LEF) plus the placebo of XFC for twelve weeks.The clinical and laboratory parameters were compared at baseline and fourth,eighth,and twelfth weeks.RESULTS:After twelve-week treatment,patients in two groups all showed some trend of effectiveness when compared in terms of American Rheumatism Association(ACR) recommended 20%,50%,70%improvement criteria,but it was insignificant.The validity in ameliorate modified disease activity score(DAS28) and laboratory indexes as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),rheumatoid factor(RF) were also found no difference.The score of health assessment questionnaire(HAQ),self-rating anxiety scale(SAS),self-rating depression scale(SDS) and quality of life questionnaire with rheumatoid arthritis(RAQOL)both lower than the first week and the changes showed no difference.However,the score of SDS dropped more in XFC group than in the other.A total of 147 adverse reaction cases were reported,which shows no difference between the two groups.The most common adverse reactions were hepatic impairment,anemia,leukocytopenia,epigastric discomfort and phalacrosis.CONCLUSION:XFC demonstrated better improvement in the scores of SDS and compared with those of LEF group. | Liu Jian Wang Yuan Huang Chuanbing Xu Jianhua Li Zhijun Xu Liang He Liyun Sun Yue Wang Yali Xu Shengqian Zhao Ping Mao Tongjun Tan Bin Zhu Fubing Zhang Pingheng Fang Li | 2015 | Journal of Traditional Chinese Medicine2015,35,5: | 27 |
| 18 | Prognostic significance of combined fibrinogen concentration and neutrophil-to-lymphocyte ratio in patients with resectable non-small cell lung cancer显示文摘Objective:Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival.In this study,we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio(NLR)in predicting the survival of patients with non-small cell lung cancer(NSCLC).Methods:We retrospectively enrolled 589 patients with NSCLC who underwent surgery.The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators,including the combination of fibrinogen and NLR(F-NLR).The cut-off values for fibrinogen,NLR,and clinical laboratory variables were defined by the receiver operating characteristic(ROC)curve analysis.According to the ROC curve,the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30,respectively.Patients with both a high NLR(≥2.30)and hyperfibrinogenemia(≥3.48 g/L)were given a score of 2,whereas those with one or neither were scored as 1 or 0,respectively.Results:Our results showed that F-NLR was an independent prognostic indicator for disease-free survival(DFS)[hazard ratio(HR),1.466;95%confidence interval(CI),1.243–1.730;P<0.001]and overall survival(OS)(HR,1.512;95%CI,1.283–1.783;P<0.001).The five-year OS rates were 66.1%,53.5%,and 33.3%for the F-NLR=0,F-NLR=1,and F-NLR=2,respectively(P<0.001).Correspondingly,their five-year DFS rates were 62.2%,50.3%,and 30.4%,respectively(P<0.001).In the subgroup analyses of the pathological stages,the F-NLR level was significantly correlated with DFS and OS in stage I and IIIA cancers.Conclusions:Preoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC. | Wuhao Huang Shengguang Wang Hua Zhang Bin Zhang Changli Wang | 2018 | Cancer Biology & Medicine2018,15,1: | 27 |
| 19 | Comparison of extracorporeal and conventional cardiopulmonary resuscitation:A meta-analysis of 2 260 patients with cardiac arrest显示文摘BACKGROUND: This meta-analysis aimed to determine whether extracorporeal cardiopulmonary resuscitation(ECPR), compared with conventional cardiopulmonary resuscitation(CCPR), improves outcomes in adult patients with cardiac arrest(CA).DATA RESOURCES: Pub Med, EMBASE, Web of Science, and China Biological Medicine Database were searched for relevant articles. The baseline information and outcome data(survival, good neurological outcome at discharge, at 3–6 months, and at 1 year after CA) were collected and extracted by two authors. Pooled risk ratios(RRs) and 95% confidence intervals(CIs) were calculated using Review Manager 5.3.RESULTS: In six studies 2 260 patients were enrolled to study the survival rate to discharge and longterm neurological outcome published since 2000. A signi? cant effect of ECPR was observed on survival rate to discharge compared to CCPR in CA patients(RR 2.37, 95%CI 1.63–3.45, P<0.001), and patients who underwent ECPR had a better long-term neurological outcome than those who received CCPR(RR 2.79, 95%CI 1.96–3.97, P<0.001). In subgroup analysis, there was a significant difference in survival to discharge favoring ECPR over CCPR group in OHCA patients(RR 2.69, 95%CI 1.48–4.91, P=0.001). However, no signi? cant difference was found in IHCA patients(RR 1.84, 95%CI 0.91–3.73, P=0.09).CONCLUSION: ECPR showed a bene? cial effect on survival rate to discharge and long-term neurological outcome over CCPR in adult patients with CA. | Gan-nan Wang Xu-feng Chen Li Qiao Yong Mei Jin-ru Lv Xi-hua Huang Bin Shen Jin-song Zhang | 2017 | World Journal of Emergency Medicine2017,8,1: | 25 |
| 20 | Single-photon computational 3D imaging at 45 km显示文摘Single-photon light detection and ranging(lidar)offers single-photon sensitivity and picosecond timing resolution,which is desirable for high-precision three-dimensional(3 D)imaging over long distances.Despite important progress,further extending the imaging range presents enormous challenges because only a few echo photons return and are mixed with strong noise.Here,we tackled these challenges by constructing a high-efficiency,low-noise coaxial single-photon lidar system and developing a long-range-tailored computational algorithm that provides high photon efficiency and good noise tolerance.Using this technique,we experimentally demonstrated active single-photon 3 D imaging at a distance of up to 45 km in an urban environment,with a low return-signal level of^1 photon per pixel.Our system is feasible for imaging at a few hundreds of kilometers by refining the setup,and thus represents a step towards low-power and high-resolution lidar over extra-long ranges. | ZHENG-PING LI XIN HUANG YUAN CAO BIN WANG YU-HUAI LI WEIJIE JIN CHAO YU JUN ZHANG QIANG ZHANG CHENG-ZHI PENG FEIHU XU AND JIAN-WEI PAN | 2020 | Photonics Research2020,8,9: | 24 |
