1Identification 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 2020Chinese Medical Journal2020,,9:99
2The origin, transmission and clinical therapies on coronavirus disease 2019(COVID-19) outbreak——an update on the status显示文摘An acute respiratory disease,caused by a novel coronavirus(SARS-CoV-2,previously known as 2019-nCoV),the coronavirus disease 2019(COVID-19)has spread throughout China and received worldwide attention.On 30 January 2020,World Health Organization(WHO)officially declared the COVID-19 epidemic as a public health emergency of international concern.The emergence of SARS-CoV-2,since the severe acute respiratory syndrome coronavirus(SARSCoV)in 2002 and Middle East respiratory syndrome coronavirus(MERS-CoV)in 2012,marked the third introduction of a highly pathogenic and large-scale epidemic coronavirus into the human population in the twenty-first century.As of 1 March 2020,a total of 87,137 confirmed cases globally,79,968 confirmed in China and 7169 outside of China,with 2977 deaths(3.4%)had been reported by WHO.Meanwhile,several independent research groups have identified that SARS-CoV-2 belongs toβ-coronavirus,with highly identical genome to bat coronavirus,pointing to bat as the natural host.The novel coronavirus uses the same receptor,angiotensin-converting enzyme 2(ACE2)as that for SARS-CoV,and mainly spreads through the respiratory tract.Importantly,increasingly evidence showed sustained human-tohuman transmission,along with many exported cases across the globe.The clinical symptoms of COVID-19 patients include fever,cough,fatigue and a small population of patients appeared gastrointestinal infection symptoms.The elderly and people with underlying diseases are susceptible to infection and prone to serious outcomes,which may be associated with acute respiratory distress syndrome(ARDS)and cytokine storm.Currently,there are few specific antiviral strategies,but several potent candidates of antivirals and repurposed drugs are under urgent investigation.In this review,we summarized the latest research progress of the epidemiology,pathogenesis,and clinical characteristics of COVID-19,and discussed the current treatment and scientific advancements to combat the epidemic novel coronavirus.Yan-Rong Guo Qing-Dong Cao Zhong-Si Hong Yuan-Yang Tan Shou-Deng Chen Hong-Jun Jin Kai-Sen Tan De-Yun Wang Yan Yan 2020Military Medical Research2020,7,1:123
3Long-term efficacy of perioperative chemoradiotherapy on esophageal squamous cell carcinoma显示文摘AIM: To investigate the role of perioperative chemoradiotherapy (CRT) in the treatment of locally advanced thoracic esophageal squamous cell carcinoma (ESCC). METHODS: Using preoperative computed tomography (CT)-based staging criteria, 238 patients with ESCC (stage ⅡⅢ ) were enrolled in this prospective study between January 1997 and June 2004. With informed consent, patients were randomized into 3 groups: preoperative CRT (80 cases), postoperative CRT (78 cases) and surgery alone (S) (80 cases). The 1-, 3-, 5and 10-year survival were followed up. Progressionfree survival (PFS) was chosen as the primary endpoint by treatment arm measured from study entry until documented progression of disease or death from any cause. The secondary endpoint was overall survival (OS) determined as the time (in months) between the date of therapy and the date of death. Other objectives were surgical and adjuvant therapy complications.RESULTS: With median follow-up of 45 mo for all the enrolled patients, significant differences in the 1-, 3-, 5-, 10-year OS (91.3%, 63.5%, 43.5%, 24.5% vs 91%, 62.8%, 42.3%, 24.4% vs 87.5%, 51.3%, 33.8%, 12.5%, P = 0.0176) and PFS (89.3%, 61.3%, 37.5%, 18.1% vs 89.1%, 61.1%, 37.2%, 17.8% vs 84.5%, 49.3%, 25.9%, 6.2%, P = 0.0151) were detected among the 3 arms. There were no significant differences in OS and PFS between the preoperative CRT and postoperative CRT arm (P > 0.05). For the patients who had radical resection, significant differences in median PFS (48 mo vs 61 mo vs 39.5 mo, P = 0.0331) and median OS (56.5 mo vs 72 mo vs 41.5 mo, P = 0.0153) were detected among the 3 arms, but there were no significant differences in OS and PFS between the preoperative CRT and postoperative CRT arm (P > 0.05). The local recurrence rates in the preoperative CRT, postoperative CRT group and S group were 11.3%, 14.1% and 35%, respectively (P < 0.05). No significant differences were detected among the 3 groups when comparing complications but tended to be in favor of the postoperative CRT and S groups (P > 0.05). Toxicities of CRT in the preoperative or postoperative CRT arms were mostly moderate, and could be quickly alleviated by adequate therapy. CONCLUSION: Rational application of preoperative or postoperative CRT can provide a benefit in PFS and OS in patients with locally advanced ESCC.Lv, Jin Cao, Xiu-Feng Zhu, Bin Ji, Lv Tao, Lei Wang, Dong-Dong 2010World Journal of Gastroenterology2010,16,13:49

7Carbon isotope excursions across the Permian-Triassic boundary in the Meishan section, Zhejiang Province, China显示文摘Both gradual and sharp decrease in organic and carbonate carbon isotope values were detected across the Permian-Triassic boundary in the Meishan section, Changxing, Zhejiang Province, China. The gradual decrease in organic carbon isotope values started at the bottom of Bed 23, coinciding with the strong oscillations of total organic carbon (TOC) contents, indicates increasing fluxes from carbonate to organic carbon reservoir during this interval. A 2.3‰ sharp drop of inorganic carbon isotope values occurred at the uppermost part of Bed 24e. A 3.7‰ sharp drop of organic carbon isotope values occurred in Bed 26. The dramatic drop of inorganic carbon isotope value of 8‰ reported previously is not confirmed from the unweathered carbonate samples in Bed 27. The large-scale fluctuation of organic carbon isotope values in the Yinkeng Formation reflects different extent of mixing of marine and terrestrial organic matters. The gradual depletion and subsequent sharp drop of carbon isotopes near theChangqun Cao Wei Wang Yugan Jin 2002Chinese Science Bulletin2002,47,13:33
8Effect of neoadjuvant chemoradiotherapy on prognosis and surgery for esophageal carcinoma显示文摘AIM:To investigate the role of neoadjuvant chemoradiotherapy in prognosis and surgery for esophageal carcinoma by a meta-analysis.METHODS:PubMed and manual searches were done to identify all published randomized controlled trials(RCTs) that compared neoadjuvant chemoradiotherapy plus surgery(CRTS) with surgery alone(S) for esophageal cancer.According to the test of heterogeneity,a fi xed-effect model or a random effect model was used and the odds ratio(OR) was the principal measure of effects.RESULTS:Fourteen RCTs that included 1737 patients were selected with quality assessment ranging from A to C(Cochrane Reviewers' Handbook 4.2.2).OR(95% CI,P value),expressed as CRTS vs S(values>1 favor CRTS arm),was 1.19(0.94-1.48,P=0.28) for 1-year survival,1.33(1.07-1.65,P=0.69) for 2-year survival,1.76(1.42-2.19,P=0.11) for 3-year survival,1.41(1.06-1.87,P=0.11) for 4-year survival,1.64(1.28-2.12,P=0.40) for 5-year survival,0.82(0.39-1.73,P<0.0001) for rate of resection,1.53(1.33-2.84,P=0.007) for rate of complete resection,1.78(1.14-2.78,P=0.79) for operative mortality,1.12(0.89-2.48,P=0.503) for all treatment mortality,1.33(0.94-1.88,P=0.04) for the rate of adverse treatment,1.38(1.23-1.63,P=0.0002) for local-regional cancer recurrence,1.28(0.85-1.58,P=0.60) for distant cancer recurrence,and 1.27(0.86-1.65,P=0.19) for all cancer recurrence.A complete pathological response to chemoradiotherapy occurred in 10%-45.5% of patients.The 5-year survival benefi t was most pronounced when chemotherapy and radiotherapy were given concurrently(OR:1.45,95% CI:1.26-1.79,P=0.015) instead of sequentially(OR:0.85,95% CI:0.64-1.35,P=0.26).CONCLUSION:Compared with surgery alone,neoadjuvant chemoradiotherapy can improve the long-term survival and reduce local-regional cancer recurrence.Concurrent administration of neoadjuvant chemoradiotherapy was superior to sequential chemoradiotherapy.Jin Lv Xiu-Feng Cao Bin Zhu Lv Ji Lei Tao Dong-Dong Wang 2009World Journal of Gastroenterology2009,15,39:27

12Single-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 2020Photonics Research2020,8,9:24
13High-resolution remote sensing mapping of global land water显示文摘Land water, one of the important components of land cover, is the indispensable and important basic information for climate change studies, ecological environment assessment, macro-control analysis, etc. This article describes the overall study on land water in the program of global land cover remote sensing mapping. Through collection and processing of Landsat TM/ETM+, China's HJ-1 satellite image, etc., the program achieves an effective overlay of global multi-spectral image of 30 m resolution for two base years, namely, 2000 and 2010, with the image rectification accuracy meeting the requirements of 1:200000 mapping and the error in registration of images for the two periods being controlled within 1 pixel. The indexes were designed and selected reasonably based on spectral features and geometric shapes of water on the scale of 30 m resolution, the water information was extracted in an elaborate way by combining a simple and easy operation through pixel-based classification method with a comprehensive utilization of various rules and knowledge through the object-oriented classification method, and finally the classification results were further optimized and improved by the human-computer interaction, thus realizing high-resolution remote sensing mapping of global water. The completed global land water data results, including Global Land 30-water 2000 and Global Land 30-water 2010, are the classification results featuring the highest resolution on a global scale, and the overall accuracy of self-assessment is 96%. These data are the important basic data for developing relevant studies, such as analyzing spatial distribution pattern of global land water, revealing regional difference, studying space-time fluctuation law, and diagnosing health of ecological environment.LIAO AnPing CHEN LiJun CHEN Jun HE ChaoYing CAO Xin CHEN Jin PENG Shu SUN FangDi GONG Peng 2014Science China Earth Sciences2014,57,10:22

17Electroacupuncture improves neurovascular unit reconstruction by promoting collateral circulation and angiogenesis显示文摘Acupuncture at Shuigou(GV26) shows good clinical efficacy for treating stroke, but its mechanism remains poorly understood. In this study, a cerebral infarction model of ischemia/reperfusion injury received electroacupuncture at GV26(15 Hz and 1 m A, continuous wave [biphasic pulses], for 5 minutes). Electroacupuncture effectively promoted regional cerebral blood flow on the infarct and non-infarct sides, increased infarct lesions, lectin, and number of blood vessels, upregulated von Willebrand factor and cell proliferation marker Ki67 expression, and diminished neurological severity score. These findings confirm that electroacupuncture at GV26 promotes establishment of collateral circulation and angiogenesis, and improves neurological function.Lei Shi Hong-mei Cao Ying Li Shi-xin Xu Yan Zhang Yang Zhang Zhe-feng Jin 2017Neural Regeneration Research2017,12,12:19
18Effects of salt stress on rice growth, development characteristics, and the regulating ways: A review显示文摘Rice(Oryza sativa L.) is highly susceptible to the rhizosphere salinity than other cereals.High sensitivity has been observed,mainly at vegetative and reproductive stages in rice.It is the duty of plant physiologists to comprehend the growth,development,and physiological processes of rice plants under stress.This paper includes the overview of rice growth and developmental processes influenced by salt stress and the regulation pathways involved in these processes.It also includes the promising salt tolerance strategies,i.e.,genetic modification techniques,agronomic practices to improve rice growth,yield,and role of phytohormones and their management,especially inhibition of ethylene biosynthesis by using inhibitors 1-methylcyclopropene(1-MCP).Rice cultivation may be a first choice for improvement of salt tolerance through plant growth regulators and improved cultivation techniques.This study will significantly improve the understanding toward low rice grain yield and poor rice resistance under salt stress and will also stream scientific knowledge for effective utilization of salt affected soils by using different regulating ways.Sajid Hussain ZHANG Jun-hua ZHONG Chu ZHU Lian-feng CAO Xiao-chuang YU Sheng-miao Allen Bohr James HU Ji-jie JIN Qian-yu 2017Journal of Integrative Agriculture2017,16,11:19
19Effects of electroacupuncture at Zusanli(ST36) on inflammatory cytokines in a rat model of smokeinduced chronic obstructive pulmonary disease显示文摘OBJECTIVE:Improvement in lung function was reported after acupuncture treatment of chronic obstructive pulmonary disease(COPD),but little is known about the underlying mechanisms. Because an immune response imbalance could be seen in COPD,we hypothesize that electroacupuncture(EA) may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD. METHODS:A COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established.The rats were randomly divided into four groups(control,sham,COPD,and COPD plus EA),and COPD model was evaluated by measuring pulmonary pathological changes and lung function.EA was applied to the acupuncture point Zusanli(ST36) for 30 min/d for 14 d in sham and COPD rats.Bronchoalveolar lavage fluid(BALF) was used to measure levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and malonaldehyde(MDA). RESULTS:Compared with the control rats,COPD rats had significant changes in lung resistance(R_L) and lung compliance(C_L)(both P<0.01),bronchi and bronchiole airway obstruction(P<0.01),and levels of MDA,TNF-α,and IL-1β(P<0.01).There were no significant differences between the control and the sham groups.Compared with the COPD rats,the COPD plus EA rats had decreased R_L and increased C_L(both P<0.05),and reduced bronchi and bronchiole airway obstruction(P<0.05,P<0.01,respectively),while levels of TNF-α,IL-1β, and MDA in BALF were lowered(P<0.05 and P<0.01,respectively).However,TNF-αand IL-1βlevels of the EA group rats remained higher than those of the control group(P<0.05). CONCLUSION:EA at ST36 can reduce lung injury in a COPD rat model,and beneficial effects may be related to down-regulation of inflammatory cytokines.The anti-inflammatory and antioxidant effects mav prolong the clinical benefit of EA.Wen-ye Geng Zi-bing Liu Na-na Song Gui-hong Zhang Wei-zhong Jin Wang Zhou Li Li Yin-xiang Cao Da-nian Zhu Lin-lin Shen 2013Journal of Integrative Medicine2013,11,3:18
