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
2A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
3Mesenchymal stem cells: a new strategy for immunosuppression and tissue repair显示文摘间充质的干细胞(MSC ) 为治疗各种各样的疾病有大潜力,特别那些与织物有关损坏包含有免疫力的反应。各种各样的研究证明了 MSC 在 vitro 并且在 vivo 是强烈抑制免疫力的。我们的最近的研究证明了那未刺激的 MSC 确实不能免疫力的抑制;他们与 TNF- 伪, IL-1 伪或 IL-1 尾与激活的淋巴细胞的上层清液,或与 IFN- 纬的联合在刺激之上变得 potently 抑制免疫力。这观察表明在某些情形下面,煽动性的 cytokines 能实际上变得抑制免疫力。我们证明在调停 MSC 的免疫力的抑制的机制有一个种类变化:由告知 cytokine 的老鼠 MSC 的免疫力的抑制被氮的氧化物调停(没有) 而由告知 cytokine 的人的 MSC 的免疫力的抑制通过 indoleamine 被执行 2, 3-dioxygenase (伊多语) 。在有煽动性的 cytokines 的刺激之上,另外,老鼠和人的 MSC 分泌几白血球 chemokines 显然服务与 MSC 吸引有免疫力的房间进最近,在哪儿不或伊多语被预言很活跃。因此,由煽动性的刺激 cytokine 的 MSC 的免疫力的抑制经由 chemokines 的一致行动发生并且免疫者禁止没有或伊多语由 MSC 生产了。因此,我们的结果在对待有免疫力的回答导致的织物损害关于调停 MSC 的免疫力的抑制并且为 MSC 的更好的申请的机制提供新奇信息。Yufang Shi Gangzheng Hu Juanjuan Su Wenzhao Li Qing Chen Peishun Shou Chunliang Xu Xiaodong Chen Yin Huang Zhexin Zhu Xin Huang Xiaoyan Han Ningxia Xie Guangwen Ren 2010Cell Research2010,20,5:72
4Transmission Dynamics of an Outbreak of the COVID-19 Delta Variant B.1.617.2——Guangdong Province,China,May-June 2021显示文摘On May 21,2021,a local case of coronavirus disease 2019(COVID-19)was confirmed in a 75-year-old woman(experienced onset of symptoms on May 18)in Liwan District,Guangzhou City,Guangdong Province,China.The number of infections has increased in the following 10 days and led to 5 generations of transmission.Meng Zhang Jianpeng Xiao Aiping Deng Yingtao Zhang Yali Zhuang Ting Hu Jiansen Li Hongwei Tu Bosheng Li Yan Zhou Jun Yuan Lei Luo Zimian Liang Youzhi Huang Guoqiang Ye Mingwei Cai Gongli Li Bo Yang Bin Xu Ximing Huang Yazun Cui Dongsheng Ren Yanping Zhang Min Kang Yan Li 2021China CDC weekly2021,3,27:51
5Tibetan Plateau climate dynamics: recent research progress and outlook显示文摘This paper reviews progress in the study of Tibetan Plateau(TP) climate dynamics over the past decade.Several theoretical frameworks, including thermal adaptation and the TP sensible heat(SH) driving air-pump, have been developed to identify the mechanisms responsible for the circulation anomaly produced by thermal forcing of the TP. Numerical simulations demonstrate that the thermal efects of large-scale orography, including the Tibetan and Iranian Plateaus(TIP), are crucial for the formation of the East Asian and South Asian summer monsoons(SASM) because the surface SH of the TIP is the major driver of the water vapor transport required for the genesis of the north branch of the SASM. he large-scale orography of the TP afects the Asian climate through thermal forcing in spring and summer, and mechanical forcing in winter. he TP forcing can also inluence the Asian summer monsoon(ASM) onset over the Bay of Bengal(BOB) by enhancing the BOB warm pool at the surface and by modulating the South Asian High(SAH) in the upper troposphere. On intra-seasonal timescales, the TP thermal forcing signiicantly modulates spring rainfall in southern China and generates the biweekly oscillation of the SAH in summer. Despite climate warming, the atmospheric heat source over the TP, particularly the spring SH,exhibits a clear weakening trend from the 1980 s to 2000 s. his weakening of the spring SH contributed to the anomalous ‘dry in the north' and ‘wet in the south' rainfall patern observed over East China. Also discussed are challenges to further understanding the mechanism of TP forcing on the multi-scale variability of the ASM.Guoxiong Wu Anmin Duan Yimin Liu Jiangyu Mao Rongcai Ren Qing Bao Bian He Boqi Liu Wenting Hu 2015National Science Review2015,2,1:51

11Chronic Hepatitis B Infection with Low Level Viremia Correlates with the Progression of the Liver Disease显示文摘Background and Aims:Currently,insufficient clinical data are available to address whether low-level viremia(LLV)observed during antiviral treatment will adversely affect the clinical outcome or whether treatment strategies should be altered if LLV occurs.This study compared the clinical out-comes of patients with a maintained virological response(MVR)and patients who experienced LLV and their treatment strategies.Methods:A retrospective cohort of 674 patients with chronic hepatitis B virus(HBV)infection who received antiviral treatment for more than 12 months was analyzed for the development of end-stage liver disease and treatment strategies during the follow-up period.End-stage liver disease included decompensated liver cirrhosis and hepatocellular carcinoma(HCC).Results:During a median 42-month follow-up,end-stage liver disease developed more frequently in patients who experienced LLV than in those who experienced MVR(7.73%and 15.85%vs.0.77%and 5.52%at 5 and 10 years,respectively;p=0.000).The trend was consistent after propensity score matching.In the high-risk group of four HCC risk models,LLV patients had a higher risk of HCC development(p<0.05).By Cox proportional hazard model analysis,LLV was an independent risk factor for end-stage liver disease and HCC(hazard ratio[HR]=6.280,confidence interval[CI]=2.081-18.951,p=0.001;HR=5.108,CI=1.392-18.737,respectively;p=0.014).Patients achieved a lower rate of end-stage liver disease by adjusting treatment compared to continuing the original treatment once LLV occurred(p<0.05).Conclusions:LLV is an independent risk factor for end-stage liver disease and HCC,and treatment adjustments can be considered.Qian Zhang Hong Peng Xiaoqing Liu Huimin Wang Jinjie Du Xinhua Luo Hong Ren Peng Hu 2021Journal of Clinical and Translational Hepatology2021,9,6:25

13TANDEM and GMAW Twin Wire Welding of Q690 Steel Used in Hydraulic Support显示文摘Compared with using semi-automatic gas shielded arc welding, using automatic TANDEM twin wire welding and twin wire gas metal arc welding (GMAW) to weld Q690 steel, a low-alloy high-strength structural steel used in the hydraulic support in the fully-mechanized mining face, the welding speed, deposition rate, production environment and welding quality can be obviously improved. Compared with GMAW twin wire welding, a refined microstructure in the weld and heat-affected zone (HAZ), narrow HAZ and improved joint strength were achieved with TANDEM on Q690. Also, due to the push-pull pulsed way in TANDEM welding, the droplet transfer, distribution on heat flow and interaction between two arcs were completely different from those in GMAW twin wire system. The heat input of TANDEM is only about 76.6% of GMAW, and correspondingly, the welding speed and welding seam can be obviously improved. The complete oscillation caused by TANDEM pulsed current occurred in the welding pool, which refined the grains in the microstructure. The results show that TANDEM twin wire welding is very suitable in the welding of Q690 used in the hydraulic support.FANG Chen-fu MENG Xiao-hui HU Qing-xian WANG Feng-jiang REN He WANG Hai-song GUO Yu MAO Ming 2012Journal of Iron and Steel Research(International)2012,19,5:22

15GSDMB promotes non-canonical pyroptosis by enhancing caspase-4 activity显示文摘Gasdermin B (GSDMB) has been reported to be associated with immune diseases in humans, but the detailed molecular mechanisms remain unsolved. The N-terminus of GSDMB by itself, unlike other gasdermin family proteins, does not induce cell death. Here, we show that GSDMB is highly expressed in the leukocytes of septic shock patients, which is associated with increased release of the gasdermin D (GSDMD) N-terminus. GSDMB expression and the accumulation of the N-terminal fragment of GSDMD are induced by the activation of the non-canonical pyroptosis pathway in a human monocyte cell line. The downregulation of GSDMB alleviates the cleavage of GSDMD and cell death. Consistently, the overexpression of GSDMB promotes GSDMD cleavage, accompanied by increased LDH release. We further found that GSDMB promotes caspase-4 activity, which is required for the cleavage of GSDMD in non-canonical pyroptosis, by directly binding to the CARD domain of caspase-4. Our study reveals a GSDMB-mediated novel regulatory mechanism for non-canonical pyroptosis and suggests a potential new strategy for the treatment of inflammatory diseases.Qin Chen Peiliang Shi Yufang Wang Dayuan Zou Xiuwen Wu Dingyu Wang Qiongyuan Hu Yujie Zou Zan Huang Jianan Ren Zhaoyu Lin Xiang Gao 2019Journal of Molecular Cell Biology2019,11,6:22
16Inferring three-dimensional surface displacement field by combining SAR interferometric phase and amplitude information of ascending and descending orbits显示文摘Conventional Interferometric Synthetic Aperture Radar(InSAR) technology can only measure one-dimensional surface displacement(along the radar line-of-sight(LOS) direction).Here we presents a method to infer three-dimensional surface displacement field by combining SAR interferometric phase and amplitude information of ascending and descending orbits.The method is realized in three steps:(1) measuring surface displacements along the LOS directions of both ascending and descending orbits based on interferometric phases;(2) measuring surface displacements along the azimuth directions of both the ascending and descending orbits based on the SAR amplitude data;and(3) estimating the three-dimensional(3D) surface displacement field by combining the above four independent one-dimensional displacements using the method of least squares and Helmert variance component estimation.We apply the method to infer the 3D surface displacement field caused by the 2003 Bam,Iran,earthquake.The results reveal that in the northern part of Bam the ground surface experienced both subsidence and southwestward horizontal movement,while in the southern part uplift and southeastward horizontal movement occurred.The displacement field thus determined matches the location of the fault very well with the maximal displacements reaching 22,40,and 30 cm,respectively in the up,northing and easting directions.Finally,we compare the 3D displacement field with that simulated from the Okada model.The results demonstrate that the method presented here can be used to generate reliable and highly accurate 3D surface displacement fields.HU Jun LI ZhiWei ZHU JianJun REN XiaoChong DING XiaoLi 2010Science China Earth Sciences2010,53,4:21
17Effects of Nitrogen Application on Chlorophyll Fluorescence Parameters and Leaf Gas Exchange in Naked Oat显示文摘Naked oat(Avena nuda L.)was originated from China,where soil nitrogen(N)is low availability.The responses of chlorophyll(Chl.)fluorescence parameters and leaf gas exchange to N application were analysed in this study.After the N application rate ranged from 60 to 120 kg ha-1,variable fluorescence(F v),the maximal fluorescence(F m),the maximal photochemical efficiency(F v/F m),quantum yield(ΦPS II)of the photosynthetic system II(PS II),electron transport rate(ETR),and photochemical quenching coefficient(qP)increased with N application level,however,non-photochemical quenching coefficient(qN)decreased.Moreover,there was no difference in initial fluorescence(F o)with further more N enhancement.The maximum net photosynthetic rate(P max),apparent dark respiration rate(R d)and light saturation point(LSP)were improved with 40-56 kg N ha-1as basal fertilizer and 24-40 kg N ha-1as top dressing fertilizer applied at jointing stage.Initial quantum yield(α)was decreased with 24 kg N ha-1as basal fertilizer and 56 kg N ha-1as top dressing fertilizer.Flag-leaf net photosynthetic rate(P n)was significantly enhanced at the jointing and heading stages with 40-56 kg N ha-1as basal fertilizer;in addition,increased at grain filling stage of naked oat with 40-56 kg N ha-1as top dressing fertilizer.90 kg N ha-1(50-70%as basal fertilizer and 30-50%as top dressing fertilizer)application is recommended to alleviate photodamage of photosystem and improve the photosynthetic rate in naked oat.LIN Ye-chun HU Yue-gao REN Chang-zhong GUO Lai-chun WANG Chun-long JIANG Ying WANG Xue-jiao Phendukani Hlatshwayo ZENG Zhao-hai 2013Journal of Integrative Agriculture2013,12,12:20
18Soil Aggregate Stability and Aggregate-Associated Carbon Under Different Tillage Systems in the North China Plain显示文摘The influences of tillage systems on soil carbon(C) stocks have been studied extensively,but the distribution of soil C within aggregate fractions is not well understood.The objective of this study was to determine the influences of various tillage systems on soil aggregation and aggregate-associated C under wheat(Triticum aestivum L.) and corn(Zea mays L.) double cropping systems in the North China Plain.The experiment was established in 2001,including four treatments:moldboard plow(MP) with residue(MP+R) and without residue(MP-R),rotary tillage with residue(RT),and no-till with residue(NT).In 2007 soil samples were collected from the 0-5,5-10,and 10-20 cm depths,and were separated into four aggregate-size classes(>2 000,250-2 000,53-250,and<53μm) by wet-sieving method.Aggregate-associated C was determined,and the relationships between total soil C concentration and aggregation-size fractions were examined.The results showed that NT and RT treatments significantly increased the proportion of macroaggregate fractions(>2 000 and 250-2 000μm) compared with the MP-R and MP+R treatments.Averaged across all depths,mean weight diameters of aggregates(MWD) in NT and RT were 47 and 20%higher than that in MP+R.The concentration of bulk soil organic C was positively correlated with MWD(r=0.98;P=0.024) and macroaggregate fraction(r=0.96;P=0.036) in the 0-5 cm depth.In the 0-20 cm depth,comparing with MP+R,total C occluded in the>2 000μm fraction was increased by 9 and 6%under NT and RT,respectively.We conclude that adoption of conservation tillage system,especially no-till,can increase soil macro-aggregation and total C accumulation in macroaggregates,which may improve soil C sequestration in the intensive agricultural region of the North China Plain.DU Zhang-liu REN Tu-sheng HU Chun-sheng ZHANG Qing-zhong Humberto Blanco-Canqui 2013Journal of Integrative Agriculture2013,12,11:20
19The China Alzheimer Report 2022显示文摘China’s population has rapidly aged over the recent decades of social and economic development as neurodegenerative disorders have proliferated,especially Alzheimer’s disease(AD)and related dementias(ADRD).AD’s incidence rate,morbidity,and mortality have steadily increased to make it presently the fifth leading cause of death among urban and rural residents in China and magnify the resulting financial burdens on individuals,families and society.The‘Healthy China Action’plan of 2019-2030 promotes the transition from disease treatment to health maintenance for this expanding population with ADRD.This report describes related epidemiological trends,evaluates the economic burden of the disease,outlines current clinical diagnosis and treatment status and delineates existing available public health resources.More specifically,it examines the public health impact of ADRD,including prevalence,mortality,costs,usage of care,and the overall effect on caregivers and society.In addition,this special report presents technical guidance and supports for the prevention and treatment of AD,provides expertise to guide relevant governmental healthcare policy development and suggests an information platform for international exchange and cooperation.Rujing Ren Jinlei Qi Shaohui Lin Xinya Liu Peng Yin Zhihui Wang Ran Tang Jintao Wang Qiang Huang Jianping Li Xinyi Xie Yongbo Hu Shishuang Cui Yuan Zhu Xiaoping Yu Pengfei Wang Yikang Zhu Yiran Wang Yanyan Huang Yisong Hu Ying Wang Chunbo Li Maigeng Zhou Gang Wang 2022General Psychiatry2022,35,1:20
20Concurrent chemoradiotherapy combined with enteral nutrition support:a radical treatment strategy for esophageal squamous cell carcinoma patients with malignant istulae显示文摘Background: Concurrent chemoradiotherapy(CCRT) significantly increases the survival rate of esophageal squa?mous cell carcinoma(ESCC) patients with malignant fistulae. Recent clinical evidence has shown the benefits of enteral nutrition for malnourished cancer patients. In this study, we aimed to validate that, with the support of enteral nutrition, ESCC patients who develop malignant fistulae might be able to complete CCRT and achieve long?term survival.Methods: We reviewed the medical records of 652 patients with ESCC who received definitive CCRT at Sun Yat?sen University Cancer Center between January 2010 and December 2012. Treatment outcome and toxicity were ret?rospectively evaluated in 40 ESCC patients with malignant fistulae. All the 40 patients were treated with CCRT and evaluated by clinical nutritionists using nutrition risk screening(NRS) before, during, and after treatment. Twenty?two patients received a nasogastric tube, and 18 underwent percutaneous endoscopic gastrostomy feeding. The median energy intake was 2166 kcal/day. Treatment response was evaluated at 3 months after the completion of CCRT.Results: With a median follow?up of 18 months(range, 3–39 months), patients' 1?year overall survival(OS) rate was 62.5%, and the estimated OS time was 25.5 months. Univariate analysis showed that the NRS score(P n NRS score(P se to treatment(P < 0.001) were sig= 0.003), increase i= 0.024), fistula closure(P = 0.011), and responnifi?cantly associated with OS. Multivariate analysis showed that tumor response(P = 0.044) and increase in NRS score(P = 0.044) were independent predictors of OS. Grade 3 vomiting was observed in 8 patients(20.0%), grade 3 neutro?penia was observed in 11 patients(27.5%), and grade 3 cough was observed in 13 patients(32.5%); 2 patients(5.0%) died of massive bleeding during treatment.Conclusions: CCRT combined with enteral nutrition support is effective for ESCC patients with malignant fistulae. Patients have an increased potential to be cured, especially those who experience complete response and have an increase in NRS score. Careful observation and nutrition support are required for patients with advanced T?category ESCC who undergo CCRT.Li Ma Guang-Yu Luo Yu-Feng Ren Bo Qiu Hong Yang Chun-Xia Xie Song-Ran Liu Shi-Liang Liu Zhao-Lin Chen Qun Li Jian-Hua Fu Meng-Zhong Liu Yong-Hong Hu Wen-Feng Ye Hui Liu 2017Chinese Journal of Cancer2017,36,1:19
