| 1 | On the origin and continuing evolution of SARS-CoV-2显示文摘The SARS-Co V-2 epidemic started in late December 2019 in Wuhan, China, and has since impacted a large portion of China and raised major global concern. Herein, we investigated the extent of molecular divergence between SARS-CoV-2 and other related coronaviruses. Although we found only 4% variability in genomic nucleotides between SARS-CoV-2 and a bat SARS-related coronavirus(SARSr-CoV;Ra TG13), the difference at neutral sites was 17%, suggesting the divergence between the two viruses is much larger than previously estimated. Our results suggest that the development of new variations in functional sites in the receptor-binding domain(RBD) of the spike seen in SARS-Co V-2 and viruses from pangolin SARSr-Co Vs are likely caused by natural selection besides recombination. Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses had two major lineages(designated L and S), that are well defined by two different SNPs that show nearly complete linkage across the viral strains sequenced to date. We found that L lineage was more prevalent than the S lineage within the limited patient samples we examined. The implication of these evolutionary changes on disease etiology remains unclear.These findings strongly underscores the urgent need for further comprehensive studies that combine viral genomic data, with epidemiological studies of coronavirus disease 2019(COVID-19). | Xiaolu Tang Changcheng Wu Xiang Li Yuhe Song Xinmin Yao Xinkai Wu Yuange Duan Hong Zhang Yirong Wang Zhaohui Qian Jie Cui Jian Lu | 2020 | National Science Review2020，7，6： | 67 |

| 6 | Surface defect ordered Cu_(2)ZnSn(S,Se)_(4) solar cells with efficiency over 12% via manipulating local substitution显示文摘The environmentally friendly Cu_(2)ZnSn(S,Se)_(4)(CZTSSe) compounds are promising direct bandgap materials for application in thin film solar cells, but the spontaneous surface defects disordering would lead to large open-circuit voltage deficit(V_(oc,deficit)) and significantly limit kesterite photovoltaics performance,primarily arising from the generated more recombination centers and insufficient p to n conversion at p-n junction. Herein, we establish a surface defects ordering structure in CZTSSe system via local substitution of Cu by Ag to suppress disordered Cu_(Zn) defects and generate benign n-type Zn_(Ag) donors. Taking advantage of the decreased annealing temperature of Ag F post deposition treatment(PDT), the high concentration of Ag incorporated into surface absorber facilitates the formation of surface ordered defect environment similar to that of efficient CIGS PV. The manipulation of highly doped surface structure could effectively reduce recombination centers, increase depletion region width and enlarge the band bending near p-n junction. As a result, the Ag F-PDT device finally achieves maximum efficiency of 12.34% with enhanced V_(oc) of 0.496 V. These results offer a new solution route in surface defects and energy-level engineering, and open the way to build up high quality p-n junction for future development of kesterite technology. | Changcheng Cui Dongxing Kou Wenhui Zhou Zhengji Zhou Shengjie Yuan Yafang Qi Zhi Zheng Sixin Wu | 2022 | Journal of Energy Chemistry2022，31，4： | 4 |

| 8 | The role of intraoperative electron radiotherapy in centrally located hepatocellular carcinomas treated with narrow-margin (<1 cm) hepatectomy: a prospective, phase 2 study显示文摘Background: Postoperative radiotherapy (RT) is known to play an important role in the treatment of hepatocellular carcinomas (HCCs), but the specific role of intraoperative electron radiotherapy (IOERT) in HCCs remains unclear. The aim of this study was to investigate the safety and efficacy of IOERT in centrally located HCCs treated with narrow-margin (<1 cm) hepatectomy. Methods: This was a single-center, phase 2, prospective non-randomized controlled study, including 268 patients with centrally located HCCs who underwent narrow-margin hepatectomy. The patients were subsequently allocated to the IOERT group (n=59) or to the control group (n=65). The primary outcome of the study was to compare recurrence-free survival (RFS) between the IOERT group and the control group, and the secondary outcome was to compare overall survival (OS) rate between the two groups. Results: Of 268 patients enrolled, a total of 124 were included in the study: 59 in IOERT group, 65 in control group. The 1-, 2-, 3-year RFS rates were 79.3%, 62.1% and 45.8% for patients in the IOERT group, and 47.6%, 28.6%, and 22.9% for patients in the control group, respectively (P=0.025). The 1-, 2-, and 3-year OS rates were 100.0%, 94.9%, and 83.7% for patients in the IOERT group, and 92.3%, 87.5%, and 79.4% for patients in the control group, respectively (P=0.314). Subgroup analysis of MVI (+) patients revealed that RFS and OS are significantly prolonged in the IOERT subgroup as compared to the control, whereas there was no significant difference of RFS and OS between the two groups in MVI (−) patients. Conclusions: IOERT for centrally located HCCs with concurrent narrow-margin hepatectomy was feasible and safe. Statistically better RFS rate was observed in the IOERT group compared to the control group. Subgroup analysis revealed that IOERT was more beneficial for postoperative survival of HCC patients with MVI.

| 17 | Perspective on the application of genome sequencing for monkeypox virus surveillance显示文摘Monkeypox virus(MPXV),a DNA virus belonging to the Orthopoxvirus genus,causes a self-limiting zoonotic disease known as mpox.The human monkeypox infection was first recorded in a 9-month-old child in the Republic of Congo in the 1970s(Ladnyj et al.,1972).For a long time,mpox was mainly prevalent in the humid forests of Central Africa and parts of West Africa(Kabugae and El Zowalaty,2019).In recent years,MPXV has been spread to other countries through trade and travel.In 2003,a group of rare pets carrying MPXV was exported from Africa to the United States,and an outbreak of animal-to-human transmission occurred(Di Giulio and Eckburg,2004).In 2018,two cases of mpox were confirmed in travelers from Nigeria to the United Kingdom and one case was confirmed in Israel(Vaughan et al.,2018;Erez et al.,2019).Then,in 2019,one case was confirmed in Singapore(Ng et al.,2019).The outbreak of mpox in multiple non-endemic countries in North America and Europe started in May 2022(WHO,2022b).On July 23,2022,the WHO declared MPXV a Public Health Emergency of International Concern(PHEIC)(WHO,2022a).As of March 5,2023,86,309 confirmed mpox cases have been reported from 107 countries/regions worldwide(WHO,2023).In the mainland of China,the first imported case was confirmed by the Chinese Center for Disease Control and Prevention(Zhao et al.,2022),making this the fifth confirmed mpox infection in China.Neglected zoonotic mpox has been restricted in Africa but now it is back in the spotlight worldwide(Tan and Gao,2022). | Yuda Chen Changcheng Wu Ruhan A Li Zhao Zhongxian Zhang Wenjie Tan | 2023 | Virologica Sinica2023，38，2： | 0 |
| 18 | A review of occluded objects detection in real complex scenarios for autonomous driving显示文摘Autonomous driving is a promising way to future safe,efficient,and low-carbon transportation.Real-time ac-curate target detection is an essential precondition for the generation of proper following decision and control signals.However,considering the complex practical scenarios,accurate recognition of occluded targets is a major challenge of target detection for autonomous driving with limited computational capability.To reveal the overlap and difference between various occluded object detection by sharing the same available sensors,this paper presents a review of detection methods for occluded objects in complex real-driving scenarios.Considering the rapid development of autonomous driving technologies,the research analyzed in this study is limited to the recent five years.The study of occluded object detection is divided into three parts,namely occluded vehicles,pedes-trians and traffic signs.This paper provided a detailed summary of the target detection methods used in these three parts according to the differences in detection methods and ideas,which is followed by the comparison of advantages and disadvantages of different detection methods for the same object.Finally,the shortcomings and limitations of the existing detection methods are summarized,and the challenges and future development prospects in this field are discussed. | Jiageng Ruan Hanghang Cui Yuhan Huang Tongyang Li Changcheng Wu Kaixuan Zhang | 2023 | Green Energy and Intelligent Transportation2023，2，3： | 0 |
| 19 | Synthesis of magnetic Pb/Fe_(3)O_(4)/SiO_(2) and its catalytic activity for propylene carbonate synthesis via urea and 1,2-propylene glycol显示文摘To facilitate the recovery of Pb/SiO_(2) catalyst,magnetic Pb/Fe_(3)O_(4)/SiO_(2) samples were prepared separately by emulsification,sol-gel and incipient impregnation methods.The catalyst samples were characterized by means of X-ray diffraction and N_(2) adsorption-desorption,and their catalytic activity was investigated in the reaction for synthesizing propylene carbonate from urea and 1,2-propylene glycol.When the gelatin was applied in the preparation of Fe_(3)O_(4) at 60℃ and the pH value was controlled at 4 in the preparation of Fe_(3)O_(4)/SiO_(2),the Pb/Fe_(3)O_(4)/SiO_(2) sample shows good catalytic activity and magnetism.Under the reaction conditions of a reaction temperature of 180℃,reaction time of 2h,catalyst percentage of 1.7 wt-% and a molar ratio of urea to PG of 1∶4,the yield of propylene carbonate attained was 87.7%. | Hualiang AN Xinqiang ZHAO Zhiguang JIA Changcheng WU Yanji WANG | 2009 | Frontiers of Chemical Science and Engineering2009，3，2： | 0 |
| 20 | Genomic Recombination of SARS-CoV-2 Subvariants BA.5.2.48 and BF.7.14—China,2023显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),a single-stranded positive RNA virus,exhibits a high rate of genome mutation and recombination(1–2).Recombinant strains of this virus could potentially affect their binding ability to the ACE2 receptor,which may in turn diminish the protection offered by vaccines and neutralizing antibodies.Notably,the Delta and Omicron recombinations have been collectively referred to as Deltacron(3).Furthermore,XBB.1.5,a recombinant strain resulting from the combination of the BA.2 sublineages BA.2.10.1 and BA.2.75,has demonstrated enhanced transmissibility(4).As such,it is imperative to monitor the genome recombination of SARS-CoV-2 in order to provide valuable insights regarding epidemic and transmission trends. | Zhongxian Zhang Han Li Hongxia Ma Wenling Wang Dawei Gao Fei Ye Weibang Huo Yuda Chen Changcheng Wu Wenjie Tan | 2023 | China CDC weekly2023，5，14： | 0 |
