| 1 | NbN superconducting nanowire single photon detector with efficiency over 90% at 1550 nm wavelength operational at compact cryocooler temperature显示文摘The rapid development of superconducting nanowire single-photon detectors over the past decade has led to numerous advances in quantum information technology. The record for the best system detection efficiency at an incident photon wavelength of 1550 nm is 93%. This performance was attained from a superconducting nanowire single-photon detector made of amorphous WSi; such detectors are usually operated at sub-Kelvin temperatures. In this study, we first demonstrate superconducting nanowire single-photon detectors made of polycrystalline NbN with system detection efficiency of 90.2% for 1550-nm-wavelength photons at2.1 K, accessible with a compact cryocooler. The system detection efficiency saturated at 92.1% when the temperature was lowered to 1.8 K. We expect the results lighten the practical and high performance superconducting nanowire single-photon detectors to quantum information and other high-end applications. | WeiJun Zhang LiXing You Hao Li Jia Huang ChaoLin Lv Lu Zhang XiaoYu Liu JunJie Wu Zhen Wang XiaoMing Xie | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，12： | 9 |
| 2 | Protecting healthcare personnel from 2019-nCoV infection risks:lessons and suggestions显示文摘The outbreak of a novel coronavirus disease(COVID-19,caused by the 2019-nCoV infection)in December 2019 is one of the most severe public health emergencies since the founding of People’s Republic of China in 1949.Healthcare personnel(HCP)nationwide are facing heavy workloads and high risk of infection,especially those who care for patients in Hubei Province.Sadly,as of February 20,2020,over two thousand COVID-19 cases are confirmed among HCP from 476 hospitals nationwide,with nearly 90%of them from Hubei Province.Based on literature search and interviews with some HCP working at Wuhan,capital city of Hubei,we have summarized some of the effective measures taken to reduce infection among HCP,and also made suggestions for improving occupational safety during an infectious disease outbreak.The experience and lessons learned should be a valuable asset for international health community to contain the ongoing COVID-19 epidemic around the world. | Zhiruo Zhang Shelan Liu Mi Xiang Shijian Li Dahai Zhao Chaolin Huang Saijuan Chen | 2020 | Frontiers of Medicine2020，14，2： | 4 |
| 3 | RETRACTED ARTICLE:Human H9N2 Avian Influenza Infection:Epidemiological and Clinical Characterization of 16 Cases in China显示文摘The authors are retracting this paper owing to errors in the reported data.The paper claimed that 16 patient cases were infected with H9N2 virus.However,when the authors recently further investigated all the thirteen sera samples,no anti-H9N2 antibodies were found by the haemagglutination inhibition assay.Moreover,re-sequencing of the remaining five throat swabs showed all five samples were H1N1 virus. | Xuan Dong Jiasong Xiong Chaolin Huang Jie Xiang Wenjuan Wu Nanshan Chen Danning Wen Chao Tu Xueli Qiao Liang Kang Zhongzi Yao Dingyu Zhang Quanjiao Chen | 2021 | Virologica Sinica2021，36，3： | 3 |
| 4 | A Megatheropod Tooth from the Early Cretaceous of Fusui, Guangxi, Southern China显示文摘A nearly complete right maxillary or left dentary tooth(NHMG 10858) from the Lower Cretaceous Xinlong Formation of the Napai Basin, Fusui County, Guangxi, southern China, is described. The tooth is large in size, with a CBL of 37 mm. Given the geological age and its crown morphology, including the size, it is most likely that the tooth belongs to a carcharodontosaurid. The recovered specimen represents one of the largest theropod teeth hitherto reported from the Early Cretaceous of Asia. | MO Jinyou HUANG Chaolin XIE Shaowen Buffetaut ERIC | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 3 |
| 5 | Digital medical education empowered by intelligent fabric space显示文摘Medical education plays an important role in promoting the development of global medical science.Nevertheless,the intrinsic gap existing between institutional medical teaching and practical clinical tasks causes low education efficiency and students’weak initiative.Recent developments of sensing fabric and embedded computing,along with the advances in artificial intelligence(AI)and digital twin technology are paving the way for the transformation of medical research towards digitization.In this work,we present an intelligent fabric space based on novel functional fabric materials and digital twin networking enabled by 5G and internet of things(IoT)technologies.In this space,medical students can learn knowledge with collaborative mapping of the digital and real world,cyber-physical interaction and real-time tactile feedback.And the proposed service system will evaluate and feedback students’operational behaviors to improve their experimental skills.We provide four typical applications of intelligent fabric space for medical education,including medical education training,health and behavior tracking,operation playback and reproduction,as well as medical knowledge popularization.The proposed intelligent fabric space has the potential to promote innovative technologies for training cutting-edge medical students by effective and efficient ways. | Min Chen Rui Wang Rui Wang Yingting Zhou Zicheng He Xiaojuan Liu Muyao He Jiaxi Wang Chaolin Huang Huamin Zhou Ping Hong Chong Hou Ning Zhou Dingyu Zhang Guangming Tao | 2022 | National Science Open2022，1，1： | 2 |
| 6 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 7 | Post-mortem tissue proteomics reveals the pathogenesis of multi-organ injuries of COVID-19显示文摘Multi-organ injuries are a major complication of severe Coronavirus Disease 2019(COVID-19).However,its pathogenesis is barely understood.Herein;we profile host responses to fatal SARS-CoV-2 infection by performing quantitative proteomics of 19 post-mortem samples of 8 different organs or tissues,including lungs,liver,intestine,kidney;spleen,brain,heart and muscle,from 3 deceased COVID-19 victims during the first wave of the pandemic(Supplementary Fig.S1A and B,Tables SI-S3). | Yang Qiu Di Wu Wanshan Ning Jiqian Xu Ting Shu Muhan Huang Rong Chen Jiancheng Zhang Yang Han Qingyu Yang Ruiting Li Xiaobo Yang Yaxin Wang Xiaojing Zou Shangwen Pan Chaolin Huang Yu Xue You Shang Xi Zhou | 2021 | National Science Review2021，8，11： | 1 |
| 8 | Patients with Prolonged Positivity of SARS-CoV-2 RNA Benefit from Convalescent Plasma Therapy:A Retrospective Study显示文摘Convalescent plasma therapy has been implemented in a few cases of severe coronavirus disease 2019.No report about convalescent plasma therapy in treating patients with prolonged positivity of SARS-CoV-2 RNA has been published.In this study,we conducted a retrospective observational study in 27 patients with prolonged positivity of SARS-CoV-2 RNA,the clinical benefit of convalescent plasma therapy were analyzed.q RT-PCR test of SARS-CoV-2 RNA turned negative(B 7 days)in a part of patients(early negative group,n=15)after therapy,others(late negative group,n=12)turned negative in more than 7 days.Pulmonary imaging improvement was confirmed in 7 patients in early negative group and 8 in late negative group after CP therapy.Viral load decreased in early negative group compared with late negative group at day 3,5,7 after implementing convalescent plasma therapy.Patients in early negative group had a shorter median length of hospital stay.In conclusion,convalescent plasma therapy might help eliminate virus and shorten length of hospital stay in patients with prolonged positivity of SARS-CoV-2 RNA. | Yongran Wu Ke Hong Lianguo Ruan Xiaobo Yang Jiancheng Zhang Jiqian Xu Shangwen Pan Lehao Ren Lu Chen Chaolin Huang You Shang | 2020 | Virologica Sinica2020，35，6： | 1 |
| 9 | Alterations in Phenotypes and Responses of T Cells Within 6 Months of Recovery from COVID-19: A Cohort Study显示文摘The COVID-19 pandemic,caused by the SARS-CoV-2 infection,is a global health crisis.While many patients have clinically recovered,little is known about long-term alterations in T cell responses of COVID-19 convalescents.In this study,T cell responses in peripheral blood mononuclear cells of a long-time COVID-19 clinically recovered(20–26 weeks)cohort(LCR)were measured via flow cytometry and ELISpot.The T cell responses of LCR were comparatively analyzed against an age and sex matched short-time clinically recovered(4–9 weeks)cohort(SCR)and a healthy donor cohort(HD).All volunteers were recruited from Wuhan Jinyintan Hospital,China.Phenotypic analysis showed that activation marker PD-1 expressing on CD4^(+)T cells of LCR was still significantly lower than that of HD.Functional analysis indicated that frequencies of Tc2,Th2 and Th17 in LCR were comparable to those of HD,but Tc17 was higher than that of HD.In LCR,compared to the HD,there were fewer IFN-c producing T cells but more IL-2 secreting T cells.In addition,the circulating Tfh cells in LCR were still slightly lower compared to HD,though the subsets composition had recovered.Remarkably,SARS-CoV-2 specific T cell responses in LCR were comparable to that of SCR.Collectively,T cell responses experienced long-term alterations in phenotype and functional potential of LCR cohort.However,after clinical recovery,SARS-CoV-2 specific T cell responses could be sustained at least for six months,which may be helpful in resisting re-infection。 | Bali Zhao Maohua Zhong Qingyu Yang Ke Hong Jianbo Xia Xia Li Ying Liu Yao-Qing Chen Jingyi Yang Chaolin Huang Huimin Yan | 2021 | Virologica Sinica2021，36，5： | 1 |

| 11 | PLX8394,a RAF inhibitor,inhibits enterovirus 71 replication by blocking RAF/MEK/ERK signaling显示文摘Enterovirus 71(EV71)poses a serious threat to human health,with scattered outbreaks worldwide.There are several vaccines against a few EV71 strains but no efficient drug for the treatment of EV71 infection.Therefore,it is urgent and of significance to develop anti-EV71 drugs.Here,we found that PLX8394,a RAF inhibitor,possesses high antiviral activity against EV71 in vitro,being superior to the traditional clinical drug ribavirin.Moreover,PLX8394 exhibits broad-spectrum antiviral activity against enteroviruses.Notably,in a suckling mouse model,PLX8394 provided a 70%protection rate for EV71-infected mice,reduced the viral load in liver and heart tissues,and relieved the inflammatory response.A mechanistic study showed that PLX8394 inhibited EV71 by suppressing the RAF/MEK/ERK signaling pathway.Thus,PLX8394 lays a foundation for the development of new drugs against EV71. | Chengyuan Wu Guangyan Zhu Fang Qiu Fuli Ren Binbin Lin Dingyu Zhang Qingyu Yang Chaolin Huang | 2023 | Virologica Sinica2023，38，2： | 0 |
| 12 | Practical operation and theoretical basis of difference-in-difference regression in science of science:The comparative trial on the scientific performance of Nobel laureates versus their coauthors显示文摘Purpose:In recent decades,with the availability of large-scale scientific corpus datasets,difference-in-difference(DID)is increasingly used in the science of science and bibliometrics studies.DID method outputs the unbiased estimation on condition that several hypotheses hold,especially the common trend assumption.In this paper,we gave a systematic demonstration of DID in the science of science,and the potential ways to improve the accuracy of DID method.Design/methodology/approach:At first,we reviewed the statistical assumptions,the model specification,and the application procedures of DID method.Second,to improve the necessary assumptions before conducting DID regression and the accuracy of estimation,we introduced some matching techniques serving as the pre-selecting step for DID design by matching control individuals who are equivalent to those treated ones on observational variables before the intervention.Lastly,we performed a case study to estimate the effects of prizewinning on the scientific performance of Nobel laureates,by comparing the yearly citation impact after the prizewinning year between Nobel laureates and their prizewinning-work coauthors.Findings:We introduced the procedures to conduct a DID estimation and demonstrated the effectiveness to use matching method to improve the results.As a case study,we found that there are no significant increases in citations for Nobel laureates compared to their prizewinning coauthors.Research limitations:This study ignored the rigorous mathematical deduction parts of DID,while focused on the practical parts.Practical implications:This work gives experimental practice and potential guidelines to use DID method in science of science and bibliometrics studies.Originality/value:This study gains insights into the usage of econometric tools in science of science. | Yurui Huang Chaolin Tian Yifang Ma | 2023 | Journal of Data and Information Science2023，8，1： | 0 |
| 13 | Impact of corticosteroids on initiation and half-year durability of humoral response in COVID-19 survivors显示文摘Background:The impact of corticosteroids on humoral responses in coronavirus disease 2019(COVID-19)sur-vivors during the acute phase and subsequent 6-month period remains unknown.This study aimed to determine how the use of corticosteroids influences the initiation and duration of humoral responses in COVID-19 survivors 6 months after infection onset.Methods:We used kinetic antibody data from the lopinavir-ritonavir trial conducted at Jin Yin-Tan Hospital in January 2020,which involved adults hospitalized with severe COVID-19(LOTUS,ChiCTR2000029308).Anti-body samples were collected from 192 patients during hospitalization,and kinetic antibodies were monitored at all available time points after recruitment.Additionally,plasma samples were collected from 101 COVID-19 survivors for comprehensive humoral immune measurement at the half-year follow-up visit.The main focus was comparing the humoral responses between patients treated with systemic corticosteroid therapy and the non-corticosteroid group.Results:From illness onset to day 30,the median antibody titre areas under the receiver operating characteristic curve(AUCs)of nucleoprotein(N),spike protein(S),and receptor-binding domain(RBD)immunoglobulin G(IgG)were significantly lower in the corticosteroids group.The AUCs of N-,S-,and RBD-IgM as well as neutralizing antibodies(NAbs)were numerically lower in the corticosteroids group compared with the non-corticosteroid group.However,peak titres of N,S,RBD-IgM and-IgG and NAbs were not influenced by corticosteroids.During 6-month follow-up,we observed a delayed decline for most binding antibodies,except N-IgM(��−0.05,95%CI[−0.10,0.00])in the corticosteroids group,though not reaching statistical significance.No significant difference was observed for NAbs.However,for the half-year seropositive rate,corticosteroids significantly accelerated the decay of IgA and IgM but made no difference to N-,S-,and RBD-IgG or NAbs.Additionally,corticosteroids group showed a trend towards delayed viral clearance compared with the non-corticosteroid group,but the results were not statistically significant(adjusted hazard ratio 0.71,95%CI 0.50-1.00;P=0.0508).Conclusion:Our findings suggested that corticosteroid therapy was associated with impaired initiation of the antibody response but this did not compromise the peak titres of binding and neutralizing antibodies.Throughout the decay phase,from the acute phase to the half-year follow-up visit,short-term and low-dose corticosteroids did not significantly affect humoral responses,except for accelerating the waning of short-lived antibodies. | Yeming Wang Li Guo Guohui Fan Yang Han Qiao Zhang Lili Ren Hui Zhang Geng Wang Xueyang Zhang Tingxuan Huang Weiyang Wang Lan Chen Lixue Huang Xiaoying Gu Xinming Wang Jingchuan Zhong Ying Wang Hui Li Jiapei Yu Zhibo Liu Chaolin Huang Bin Cao Jianwei Wang | 2024 | Chinese Medical Journal Pulmonary and Critical Care Medicine2024，2，1： | 0 |
| 14 | Broad phenotypic alterations and potential dysfunction of lymphocytes in individuals clinically recovered from COVID-19显示文摘Although millions of patients have clinically recovered from COVID-19,little is known about the immune status of lymphocytes in these individuals.In this study,the peripheral blood mononuclear cells of a clinically recovered(CR)cohort were comparatively analyzed with those of an age-and sex-matched healthy donor cohort.We found that CD8^(+)T cells in the CR cohort had higher numbers of effector T cells and effector memory T cells but lower Tc1(IFN-γ^(+)),Tc2(IL-4^(+)),and Tc17(IL-17A^(+))cell frequencies.The CD4^(+)T cells of the CR cohort were decreased in frequency,especially the central memory T cell subset.Moreover,CD4^(+)T cells in the CR cohort showed lower programmed cell death protein 1(PD-1)expression and had lower frequencies of Th1(IFN-γ^(+)),Th2(IL-4^(+)),Th17(IL-17A^(+)),and circulating follicular helper T(CXCR5^(+)PD-1^(+))cells.Accordingly,the proportion of isotype-switched memory B cells(IgM−CD20^(hi))among B cells in the CR cohort showed a significantly lower proportion,although the level of the activation marker CD71 was elevated.For CD3−HLA-DR−lymphocytes in the CR cohort,in addition to lower levels of IFN-γ,granzyme B and T-bet,the correlation between T-bet and IFN-γ was not observed.Additionally,by taking into account the number of days after discharge,all the phenotypes associated with reduced function did not show a tendency toward recovery within 4-11 weeks.The remarkable phenotypic alterations in lymphocytes in the CR cohort suggest that severe acute respiratory syndrome coronavirus 2 infection profoundly affects lymphocytes and potentially results in dysfunction even after clinical recovery. | Jingyi Yang Maohua Zhong Ejuan Zhang Ke Hong Qingyu Yang Dihan Zhou Jianbo Xia Yao-Qing Chen Mingbo Sun Bali Zhao Jie Xiang Ying Liu Yang Han Mengxin Xu Xi Zhou Chaolin Huang You Shang Huimin Yan | 2021 | Journal of Molecular Cell Biology2021，13，3： | 0 |
