1A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
2Plasma exchange-centered artificial liver support system in hepatitis B virus-related acute-onchronic liver failure:a nationwide prospective multicenter study in China显示文摘BACKGROUND:Plasma exchange(PE)-centered artificial liver support system reduced the high mortality rate of hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF).But the data were diverse in different medical centers.The present prospective nationwide study was to evaluate the effects of PE on patients with HBV-ACLF at different stages.METHODS:From December 2009 to December 2011,we evaluated 250 patients at different stages of HBV-ACLF from 10 major medical centers in China.All the laboratory parameters were collected at admission,before and after PE.RESULTS:Among the 250 patients who underwent 661 rounds of PE,one-month survival rate was 61.6%; 141(56.4%) showed improvement after PE.Variables such as age(P=0.000),levels of total bilirubin(TB,P=0.000),direct bilirubin(P=0.000),total triglycerides(P=0.000),low-density lipoprotein(P=0.022),Na+(P=0.014),Cl–(P=0.038),creatinine(Cr,P=0.007),fibrinogen(P=0.000),prothrombin time(PT,P=0.000),white blood cell(P=0.000),platelet(P=0.003) and MELD(P=0.000) were significantly related to prognosis.Multivariate logistic regression analysis showed that age,disease stage,TB,Cr and PT levels were independent risk factors of mortality among HBV-ACLF patients.CONCLUSIONS:PE can improve the clinical outcome of patients with HBV-ACLF.Levels of TB,Cr and PT,age and disease stage help to predict prognosis.Jia-Jia Chen Jian-Rong Huang Qian Yang Xiao-Wei Xu Xiao-Li Liu Shao-Rui Hao Hui-Fen Wang Tao Han Jing Zhang Jian-He Gan Zhi-Liang Gao Yu-Ming Wang Shu-Mei Lin Qing Xie Chen Pan Lan-Juan Li 2016Hepatobiliary & Pancreatic Diseases International2016,15,3:48
3Effects of mixture ratio on anaerobic co-digestion with fruit and vegetable waste and food waste of China显示文摘The biochemical methane potentials for typical fruit and vegetable waste (FVW) and food waste (FW) from a northern China city were investigated,which were 0.30,0.56 m 3 CH 4/kgVS (volatile solids) with biodegradabilities of 59.3% and 83.6%,respectively.Individual anaerobic digestion testes of FVW and FW were conducted at the organic loading rate (OLR) of 3 kg VS/(m 3 ·day) using a lab-scale continuous stirred-tank reactor at 35℃.FVW could be digested stably with the biogas production rate of 2.17 m 3/(m 3 ·day) and methane production yield of 0.42 m 3 CH 4/kg VS.However,anaerobic digestion process for FW was failed due to acids accumulation.The effects of FVW:FW ratio on co-digestion stability and performance were further investigated at the same OLR.At FVW and FW mixing ratios of 2:1 and 1:1,the performance and operation of the digester were maintained stable,with no accumulation of volatile fatty acids (VFA) and ammonia.Changing the feed to a higher FW content in a ratio of FVW to FW 1:2,resulted in an increase in VFAs concentration to 1100-1200mg/L,and the methanogenesis was slightly inhibited.At the optimum mixture ratio 1:1 for co-digestion of FVW with FW,the methane production yield was 0.49 m 3 CH 4/kg VS,and the volatile solids and soluble chemical oxygen demand (sCOD) removal efficiencies were 74.9% and 96.1%,respectively.Jia Lin Jiane Zuo Lili Gan Peng Li Fenglin Liu Kaijun Wang Lei Chen Hainan Gan 2011Journal of Environmental Sciences2011,23,8:36
4Morphological study on colonic pathology in ulcerative colitis treated by moxibustion显示文摘AIM To observe the therapeutic effect ofmoxibustion on ulcerative colitis and itsinfluence on the colonic mucosal morphology.METHODS Forty-six patients with ulcerativecolitis were randomly divided into themoxibustion with herbal medicine underneathgroup and the western medicine group.Thirtypatients were treated with the abovemoxibustion and 16 patients with Salicylayefapyridine(SASP).The colonic mucosa of 13patients in the moxibustion group was observedby colonoscopy before and after the treatment.Mucin was also analyzed by H.E and AB-PASstaining.RESULTS Seventeen patients were clinicallycured,12 were improved and 1 unchanged in themoxibustion group.In the control group,5patients were clinically cured,7 improved and 4unchanged.Thirteen patients with active UCwere taken as the subjects for histopathologicanalysis in this study.The colonic mucosallesions were remarkably improved and thecharacteristic of the mucin also changed.Inmost sections,the chronic inflammation ofmucosa was geatly ameliorated(P<0.01).Theinflammatory cell infiltratation much decreased and neutrophils,disapeared in most sections(P<0.001).The goblet cells significantlyincreased(P<0.001);crypt paracrypt abscessor mucosal ulceration was seen(P<0.001).CONCLUSION The rate of cure of ulcerative colitis by moxibustion with herbal medicine beneath is superior to that by SASP. This sort of moxibustion can effectively improve the colonic mucosal lesions and restore the proportion of mucoprotein to near normal.Huan Gan Wu Li Bin Zhou Da Ren Shi Shi Min Liu Hui Rong Liu Bi Meng Zhang Han Ping Chen Lin Shan Zhang 2000World Journal of Gastroenterology2000,6,6:28
5Ketogenic diet poses a significant effect on imbalanced gut microbiota in infants with refractory epilepsy显示文摘AIM To investigate whether patients with refractory epilepsy and healthy infants differ in gut microbiota(GM),and how ketogenic diet(KD) alters GM.METHODS A total of 14 epileptic and 30 healthy infants were recruited and seizure frequencies were recorded. Stool samples were collected for 16 S r DNA sequencing using the Illumina Miseq platform. The composition of GM in each sample was analyzed with MOTHUR,and intergroup comparison was conducted by R software.RESULTS After being on KD treatment for a week,64% of epileptic infants showed an obvious improvement,with a 50% decrease in seizure frequency. GM structure in epileptic infants(P1 group) differed dramatically from that in healthy infants(Health group). Proteobacteria,which had accumulated significantly in the P1 group,decreased dramatically after KD treatment(P2 group). Cronobacter predominated in the P1 group and remained at a low level both in the Health and P2 groups. Bacteroides increased significantly in the P2 group,in which Prevotella and Bifidobacterium also grew in numbers and kept increasing.CONCLUSION GM pattern in healthy infants differed dramatically from that of the epileptic group. KD could significantly modify symptoms of epilepsy and reshape the GM of epileptic infants.Gan Xie Qian Zhou Chuang-Zhao Qiu Wen-Kui Dai He-Ping Wang Yin-Hu Li Jian-Xiang Liao Xin-Guo Lu Su-Fang Lin Jing-Hua Ye Zhuo-Ya Ma Wen-Jian Wang 2017World Journal of Gastroenterology2017,23,33:25
6Genome analysis of Taraxacum kok-saghyz Rodin provides new insights into rubber biosynthesis显示文摘The Russian dandelion Taraxacum kok-saghyz Rodin(TKS), a member of the Composite family and a potential alternative source of natural rubber(NR) and inulin, is an ideal model system for studying rubber biosynthesis. Here we present the draft genome of TKS, the first assembled NR-producing weed plant. The draft TKS genome assembly has a length of 1.29 Gb, containing 46 731 predicted protein-coding genes and68.56% repeats, in which the LTR-RT elements predominantly contribute to the genome enlargement. We analyzed the heterozygous regions/genes, suggesting its possible involvement in inbreeding depression.Through comparative studies between rubber-producing and non-rubber-producing plants, we found that enzymes of the mevalonate(MVA) pathway and rubber elongation might be critical for rubber biosynthesis, and several key isoforms have been isolated and shown to be predominantly expressed in the latex, indicating their crucial functions in rubber biosynthesis. Moreover, for two important families in rubber elongation, the CPT/CPTL and REF/SRPP families, diverse evolutionary tracks have been revealed. These results provide valuable resources and new insights into the mechanism of NR biosynthesis,and facilitate the development of alternative NR-producing crops.Tao Lin Xia Xu Jue Ruan Shizhong Liu Shigang Wu Xiujuan Shao Xiaobo Wang Lin Gan Bi Qin Yushuang Yang Zhukuan Cheng Suhua Yang Zhonghua Zhang Guosheng Xiong Sanwen Huang Hong Yu Jiayang Li 2018National Science Review2018,5,1:22
7Rapid rehabilitation technique with integrated traditional Chinese and Western medicine promotes postoperative gastrointestinal function recovery显示文摘BACKGROUND During the perioperative period, the characteristic therapy of traditional Chinese medicine is effective in improving postoperative rehabilitation. In large-scale hospitals practicing traditional Chinese medicine, there is accumulating experience related to the promotion of fast recovery in the perioperative period.AIM To evaluate the efficacy and safety of Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique.METHODS This prospective, multicenter, randomized, controlled study included two groups: Treatment group and control group. The patients in the treatment group and control group received Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique and routine treatment, respectively. Clinical observation regarding postoperative recovery of gastrointestinal function was performed, including the times to first passage of flatus, first defecation, and first normal bowel sounds. The comparison between groups was conducted through descriptive analysis, χ~2, t, F, and rank-sum tests.RESULTS There was a statistically significant difference in the time to postoperative first defecation between the treatment and control group(87.16 ± 32.09 vs 109.79 ±40.25 h, respectively;P < 0.05). Similarly, the time to initial recovery of bowel sounds in the treatment group was significantly shorter than that in the control group(61.17 ± 26.75 vs 79.19 ± 33.35 h, respectively;P < 0.05). However, there was no statistically significant difference in the time to initial exhaust between the treatment and control groups(51.54 ± 23.66 vs 62.24 ± 25.95 h, respectively;P >0.05). The hospitalization expenses for the two groups of patients were 62283.45 ±12413.90 and 62059.42 ± 11350.51 yuan, respectively. Although the cost of hospitalization was decreased in the control group, the difference was not statistically significant(P > 0.05). This clinical trial was safe without reports of any adverse reaction or event.CONCLUSION The rapid rehabilitation technique with integrated traditional Chinese and Western medicine promotes the recovery of postoperative gastrointestinal function and is significantly better than standard approach for patients after colorectal surgery.Li-Xing Cao Zhi-Qiang Chen Zhi Jiang Qi-Cheng Chen Xiao-Hua Fan Shi-Jun Xia Jin-Xuan Lin Hua-Chan Gan Tao Wang Yang-Xue Huang 2020World Journal of Gastroenterology2020,26,23:21
8Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C.Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang 2019Research in Astronomy and Astrophysics2019,19,11:17

10Research on Formation Mechanisms of Hot Dry Rock Resources in China显示文摘As an important geothermal resource, hot dry rock(HDR) reserves have been studied in many countries. HDR resources in China have huge capacity and have become one of the most important resources for the potential replacement of fossil fuels. However, HDR resources are difficult to develop and utilise. Technologies for use with HDR, such as high–temperature drilling, reservoir characterisation, reservoir fracturing, microseismic monitoring and high–temperature power stations, originate from the field of oil and drilling. Addressing how to take advantage of these developed technologies is a key factor in the development of HDR reserves. Based on the thermal crustal structure in China, HDR resources can be divided into four types: high radioactive heat production, sedimentary basin, modern volcano and the inner–plate active tectonic belt. The prospective regions of HDR resources are located in South Tibet, West Yunnan, the southeast coast of China, Bohai Rim, Songliao Basin and Guanzhong Basin. The related essential technologies are relatively mature, and the prospect of HDR power generation is promising. Therefore, analysing the formation mechanisms of HDR resources and promoting the transformation of technological achievements, large–scale development and the utilisation of HDR resources can be achieved in China.WANG Guiling LIN Wenjing ZHANG Wei LU Chuan MA Feng GAN Haonan 2016Acta Geologica Sinica(English Edition)2016,90,4:14
11Seasonal dynamics of water bloom-forming Microcystis morphospecies and the associated extracellular microcystin concentrations in large,shallow,eutrophic Dianchi Lake显示文摘The increasing occurrence of Microcystis blooms is of great concern to public health and ecosystem due to the potential hepatotoxic microcystins(MCs)produced by these colonial cyanobacteria.In order to interpret the relationships between variations of Microcystis morphospecies and extracellular MC concentrations,the seasonal dynamics of phytoplankton community composition,MC concentrations,and environmental parameters were monitored monthly from August,2009 to July,2010.The results indicated that Microcystis dominated total phytoplankton abundance from May to December(96%–99%of total biovolume),with toxic Microcystis viridis and non-toxic Microcystis wesenbergii dominating after July(constituting 65%–95%of the Microcystis population),followed by M.viridis as the sole dominant species from November to January(49%–93%).Correlation analysis revealed that water temperature and nutrient were the most important variables accounting for the occurrence of M.wesenbergii,while the dominance of M.viridis was related with nitrite and nitrate.The relatively low content of MCs was explained by the association with a large proportion of M.viridis and M.wesenbergii,small colony size of Microcystis populations,and low water temperature,pH and dissolved oxygen.The extracellular MC(mean of 0.5±0.2μg/L)of water samples analyzed by enzyme-linked immunosorbent assay(ELISA)demonstrated the low concentrations of MC in Dianchi Lake which implied the low potential risk for human health in the basin.The survey provides the first whole lake study of the occurrence and seasonal variability of Microcystis population and extracellular MCs that are of particular interest for water quality monitoring and management.Yanlong Wu Lin Li Nanqin Gan Lingling Zheng Haiyan Ma Kun Shan Jin Liu Bangding Xiao Lirong Song 2014Journal of Environmental Sciences2014,26,9:12
12Restorative effect and mechanism of mecobalamin on sciatic nerve crush injury in mice显示文摘Mecobalamin,a form of vitamin B12 containing a central metal element(cobalt),is one of the most important mediators of nervous system function.In the clinic,it is often used to accelerate recovery of peripheral nerves,but its molecular mechanism remains unclear.In the present study,we performed sciatic nerve crush injury in mice,followed by daily intraperitoneal administration of mecobalamin(65 μg/kg or 130 μg/kg) or saline(negative control).Walking track analysis,histomorphological examination,and quantitative real-time PCR showed that mecobalamin significantly improved functional recovery of the sciatic nerve,thickened the myelin sheath in myelinated nerve fibers,and increased the cross-sectional area of target muscle cells.Furthermore,mecobalamin upregulated m RNA expression of growth associated protein 43 in nerve tissue ipsilateral to the injury,and of neurotrophic factors(nerve growth factor,brain-derived nerve growth factor and ciliary neurotrophic factor) in the L4–6 dorsal root ganglia.Our findings indicate that the molecular mechanism underlying the therapeutic effect of mecobalamin after sciatic nerve injury involves the upregulation of multiple neurotrophic factor genes.Lin Gan Minquan Qian Keqin Shi Gang Chen Yanglin Gu Wei Du Guoxing Zhu 2014Neural Regeneration Research2014,9,22:11

15Achieving highly uniform two-dimensional PbI2 flakes for photodetectors via space confined physical vapor deposition显示文摘Two-dimensional(2D) PbI_2 flakes have been attracting intensive attention as one potential candidate for the modern optoelectronics. However, suffered from the instability of kinetics-driven growth, the fabricated 2D PbI_2 flakes have a wide dimensional distribution even under the same conditions. Herein, a novel facile space confined physical vapor deposition(PVD) process is provided to synthesize uniform triangle PbI_2 flakes with high quality. The confined space provides a relatively stable growth environment that renders more control on the growth kinetics, leading to highly uniform triangle PbI_2 flakes with the average size of 5 mm and thickness of 17 nm. Moreover, as-fabricated PbI_2-based photodetectors show promising stable and flexible optoelectronic performances to 470 nm light, including high responsivity(0.72 AW^(-1)), large on/off ratio up to 900, fast photoresponse speed(rise time of 13.5 ms and decay time of 20 ms) and high detectivity(1.04×10^(10) Jones). The well-controllable growth of the uniform triangle PbI_2 flakes and the detailed exploration of their optoelectronic properties are particularly valuable for their further practical applications.Yaguang Wang Lin Gan Junnian Chen Rui Yang Tianyou Zhai 2017Science Bulletin2017,62,24:10
16Plant food sources and stone tools' function at the site of Shunshanji based on starch grain analysis显示文摘The upper-middle Huai River valley(HRV) is located in the transition zone in the middle of eastern China. Previous studies have shown that the past populations in the upper HRV obtained plant food through gathering and cultivation of both rice and millet during the middle Neolithic. However, for the middle HRV it is not very clear what methods were used by humans to obtain plant food in that time. In this paper, starch grain analysis was carried out on 17 stone tools and 29 cauldron pottery sherds unearthed at Shunshanji(8.5–7.0 kyr BP), which is known as the earliest Neolithic site in the middle HRV excavated so far. Here, ancient starches from Coix lacryma-jobi, Triticeae, Oryza sativa, Trichosanthes kirilowii and one unidentified specie were recovered. This study contributes to the limited knowledge of food strategies as observed in the middle HRV. It demonstrates that both gathering and cultivation of rice took place during the middle-Neolithic. Among the identified species, Coix lacryma-jobi appears to have been the main plant food at Shunshanji. Moreover, it is clear that Oryza sativa was not consumed as much as other plant species according to the occurrence frequency of different starch grains. Starch grains were also found on the used surfaces of grinding stone implements as well as pestles, which means that these stone tools were used for food processing. In addition, axes from Shunshanji may also have been used for food processing as well as wood working because starches were also found on the edge of axes. Information about subsistence strategies and tool use at Shunshanji will also be helpful to understanding the utilization of plants and agricultural development in the middle HRV during the early-middle Neolithic period.YANG YuZhang LI WeiYa YAO Ling CHENG ZhiJie LUO WuHong ZHANG JuZhong LIN LiuGen GAN HuiYuan YAN Long 2016Science China Earth Sciences2016,59,8:9

19Blood Pressure Associated with Arsenic Methylation and Arsenic Metabolism Caused by Chronic Exposure to Arsenic in Tube Well Water显示文摘Objective The effects of arsenic exposure from drinking water, arsenic metabolism, and arsenic methylation on blood pressure(BP) were observed in this study. Methods The BP and arsenic species of 560 participants were determined. Logistic regression analysis was applied to estimate the odds ratios of BP associated with arsenic metabolites and arsenic methylation capability. Results BP was positively associated with cumulative arsenic exposure(CAE). Subjects with abnormal diastolic blood pressure(DBP), systolic blood pressure(SBP), and pulse pressure(PP) usually had higher urinary i As(inorganic arsenic), MMA(monomethylated arsenic), DMA(dimethylated arsenic), and TAs(total arsenic) than subjects with normal DBP, SBP, and PP. The i As%, MMA%, and DMA% differed slightly between subjects with abnormal BP and those with normal BP. The PMI and SMI were slightly higher in subjects with abnormal PP than in those with normal PP. Conclusion Our findings suggest that higher CAE may elevate BP. Males may have a higher risk of abnormal DBP, whereas females have a higher risk of abnormal SBP and PP. Higher urinary i As may increase the risk of abnormal BP. Lower PMI may elevate the BP. However, higher SMI may increase the DBP and SBP, and lower SMI may elevate the PP.WEI Bing Gan YE Bi Xiong YU Jiang Ping YANG Lin Sheng LI Hai Rong XIA Ya Juan WU Ke Gong 2017Biomedical and Environmental Sciences2017,30,5:9
