1On 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 2020National Science Review2020,7,6:67

4Coking wastewater treatment for industrial reuse purpose: Combining biological processes with ultrafiltration, nanofiltration and reverse osmosis显示文摘A full-scale plant using anaerobic, anoxic and oxic processes (A1/A2/O), along with a pilot-scale membrane bioreactor (MBR), nanofiltration (NF) and reverse osmosis (RO) integrated system developed by Shanghai Baosteel Chemical Co. Ltd., was investigated to treat coking wastewater for industrial reuse over a period of one year. The removals reached 82.5% (COD), 89.6% (BOD), 99.8% (ammonium nitrogen), 99.9% (phenol), 44.6% (total cyanide (T-CN)), 99.7% (thiocyanide (SCN-)) and 8.9% (fluoride), during the A1/A2/O biological treatment stage, and all parameters were further reduced by over 96.0%, except for fluoride (86.4%), in the final discharge effluent from the currently operating plant. The pilot-scale MBR process reduced the turbidity to less than 0.65 NTU, and most of the toxic organic compounds were degraded or intercepted by the A1/A2/O followed MBR processes. In addition, parameters including COD, T-CN, total nitrogen, fluoride, chloride ion, hardness and conductivity were significantly reduced by the NF-RO system to a level suitable for industrial reuse, with a total water production ratio of 70.7%. However, the concentrates from the NF and RO units were highly polluted and should be disposed of properly or further treated before being discharged.Xuewen Jin Enchao Li Shuguang Lu Zhaofu Qiu Qian Sui 2013Journal of Environmental Sciences2013,25,8:38
5Caspase-11/4 and gasdermin D-mediated pyroptosis contributes to podocyte injury in mouse diabetic nephropathy显示文摘Diabetic nephropathy(DN)is characterized by sterile inflammation with continuous injury and loss of renal inherent parenchyma cells.Podocyte is an essential early injury target in DN.The injury and loss of podocytes are closely associated with proteinuria,the early symptom of renal injury in DN.However,the exact mechanism for podocyte injury and death in DN remains ambiguous.In this study we investigated whether pyroptosis,a newly discovered cell death pathway was involved in DN.Diabetic mice were generated by high-fat diet/STZ injections.We showed that the expression levels of caspase-11 and cleavage of gasdermin D(GSDMD-N)in podocytes were significantly elevated,accompanied by reduced expression of podocyte makers nephrin and podocin,loss and fusion in podocyte foot processes,increased inflammatory cytokines NF-κB,IL-1β,and IL-18,macrophage infiltration,glomerular matrix expansion and increased urinary albumin to creatinine ratio(UACR).All these changes in diabetic mice were blunted by knockout of caspase-11 or GSDMD.Cultured human and mouse podocytes were treated with high glucose(30 mM),which significantly increased the expression levels of caspase-11 or caspase-4(the homolog of caspase-11 in human),GSDMD-N,NF-κB,IL-1β,and IL-18,and decreased the expression of nephrin and podocin.Either caspase-4 or GSDMD knockdown by siRNA significantly blunted these changes.In summary,our results demonstrate that caspase-11/4 and GSDMD-mediated pyroptosis is activated and involved in podocyte loss under hyperglycemia condition and the development of DN.Qian Cheng Jing Pan Zhuan-li Zhou Fan Yin Hong-yan Xie Pan-pan Chen Jing-yao Li Pei-qing Zheng Li Zhou Wei Zhang Jun Liu Li-min Lu 2021Acta Pharmacologica Sinica2021,42,6:33
6Deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains显示文摘Fine structures of the crust and upper mantle of the basin-and-range juncture on the northwestern margin of the Qinghai-Tibetan Plateau are first delineated by the deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains. Evidence is found for the northward subduction of the northwest marginal lithosphere of the Qinghai-Tibetan Plateau and its collision with Tarim lithosphere beneath the West Kunlun Mountains. The lithosphere image of the face-to-face subduction and collision determines the coupling relationship between the Tarim Basin and the West Kunlun Mountains at the lithosphere scale and reflects the process of continent- continent collision.GAO Rui HUANG Dongding LU Deyuan QIAN Guihua LI Yingkang KUANG Chaoyang Li Qiusheng LI Pengwu Feng Rujin Guan Ye 2000Chinese Science Bulletin2000,45,24:30
7The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping 2016Biomedical and Environmental Sciences2016,29,1:29

12Therapeutic effect of acupuncture and massage for shoulder-hand syndrome in hemiplegia patients:a clinical two-center randomized controlled trial显示文摘OBJECTIVE:To evaluate the therapeutic effects of acupuncture and massage for shoulder-hand syndrome in hemiplegia patients.METHODS:One hundred and twenty hemiplegia patients with stage I shoulder-hand syndrome were randomly divided into a group treated with standardized electric acupuncture and massage,and a group treated with rehabilitation therapy for 6 weeks.The primary indices evaluated were pain on passive movement of the shoulder using the numeric pain rating scale(NPRS),and the number of patients with shoulder-hand syndrome at Steinbrocker stage II or III after treatment.The secondary indices were Fugl-Meyer evaluation of functional movement of the upper limb and hand using the modified rankin scale(MRS).RESULTS:At post-treatment evaluation and a 12-week follow-up visit,NPRS score,number of patients with stage II or III shoulder-hand syndrome,and MRS score were all improved in the acupuncture-massage group compared with the rehabilitation group(P<0.05).On Fugl-Meyer evaluation,functional movement of the upper limb was also improved in the acupuncture-massage group compared with the rehabilitation group(P<0.05).CONCLUSION:Standardized acupuncture-massage therapy may have curative effects on shoulder-hand syndrome in hemiplegia patients.Ning Li Fengwei Tian Chengwei Wang Pengming Yu Xi Zhou Qian Wen Xiulan Qiao Lu Huang 2012Journal of Traditional Chinese Medicine2012,32,3:25
13Ketogenic 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
14Experimental study on the effect of Kang-Lai-Te induced apoptosis of human hepatoma carcinoma cell HepG2显示文摘BACKGROUND:Kang-Lai-Te(KLT)is extracted from the traditional Chinese herbal medicine Semen Coicis,which has been used in China as an effective clinical drug for over a thousand years.It contains numerous ingredients with anti-tumor effects.In our previous studies on transplanted hepatomas in rats,KLT could stop the cells in the G2+M stage of cell cycle and then reduce the number of cells entering the stage G0 and G1,but the mechanism of the anti-proliferative effect was unknown.In this experiment,we examined whether KLT inhibits HepG2 cell growth,if so,tried to explore its mechanism. METHODS:KLT at different concentrations was used for the treatment of hepatocellular carcinoma cells in vitro,respectively.The proliferation inhibitory rate was evaluated by MTT assay,induction of cell apoptosis rate and the protein levels of Fas and Fas ligand(FasL)were determined by flow cytometry(FCM),and the expression of Fas and FasL mRNA was detected by real-time fluorescent quantitative RT-PCR. RESULTS:KLT produced an obvious time and dose- dependent inhibitory effect on HepG2 cells,and marked apoptosis was detected by FCM.The protein of Fas increased by 11.01%,18.71%,28.71%and 37.15%;the protein of FasL increased by 1.49%,1.91%,3.27%and 3.38%in comparison with the control(P<0.05).Real-time fluorescent quantitative RT-PCR showed that treating HepG2 cells with KLT caused the upregulation of Fas and FasL mRNA.CONCLUSION:KLT inhibits HepG2 growth by inducing apoptosis,which may be mediated through activation of the Fas/FasL pathway.Lu, Yun Wu, Li-Qun Dong, Qian Li, Chang-Sheng 2009Hepatobiliary & Pancreatic Diseases International2009,8,3:24
15Paleoproterozoic reworking of ancient crust in the Cathaysia Block,South China:Evidence from zircon trace elements,U-Pb and Lu-Hf isotopes显示文摘A combined study of zircon LA-ICP-MS U-Pb dating, trace elements and Hf isotope was carried out for gneissic granite from the Sanzhishu area in Jingning, SW Zhejiang Province. Nearly all the zircons separated from the granite exhibited oscillatory zoning and high Th/U ratios (>0.1). The REE profile showed a pronounced positive Ce anomaly, negative Eu anomaly and an enrichment of HREE, which are typical characteristics of magmatic zircon. Thirteen concordant or nearly concordant analytical data yielded a weighted mean 207Pb/206Pb age of 1860±13 Ma (MSWD=0.084), representing the formation age of the granite. The magmatic zircons had negative εHf(t) values of -15.6 to -10.0 and two-stage Hf model ages of 3.1 to 3.4 Ga, indicating that the granites were formed by reworking of ancient crust. The major- and trace-element data indicate that the gneissic granites are metaluminous high-K calc-alkaline rocks and exhibit the same geochemical characteristics as aluminous A-type granites, implying the emplacement of the granite in a post-orogenic extensional tectonic setting. We conclude that the Pa-leoproterozoic crustal reworking event in the Cathaysia Block of South China marked the transition from assembly to break-up of the Columbia supercontinent.LIU Rui ZHOU Han Wen ZHANG Li ZHONG ZengQiu ZENG Wen XIANG Hua JIN Song LU Xin Qian LI ChunZhong 2009Chinese Science Bulletin2009,54,9:22

17Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study.ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan 2013Chinese Science Bulletin2013,58,34:22
18Effects of multimodal fast-track surgery on liver transplantation outcomes显示文摘BACKGROUND:Fast-track surgery and enhanced recovery after surgery have been applied to many surgical procedures;however,data on fast-track surgery and enhanced recovery after surgery following liver transplantation is limited.This study aimed to conduct a prospective study to determine the effects of fast-track surgery on prognosis after liver transplantation.METHODS:This was a prospective,single-blinded,randomized study.One hundred twenty-eight patients undergoing liver transplantation were selected for the fast-track(FT group,n=54) or conventional process(NFT group,n=74).The primary endpoints were intensive care unit(ICU) stay and hospital stay.The secondary endpoints were as follows:operative time,anhepatic phase time,intraoperative blood loss,intraoperative blood transfusion volume,postoperative complications,readmission rate,and postoperative mortality.RESULTS:There was no significant difference in preoperative demographics between the two groups.The median ICU stay was 2 days(range 1-7 days) in the FT group and 5 days(range 3-12 days) in the NFT group(P<0.01).Furthermore,the hospital stay was also significantly reduced in the FT group(P<0.01).The operative time,anhepatic phase time,intraoperative blood loss,and intraoperative blood transfusion volume were decreased in the FT group compared with the NFT group(P<0.05).Based on Spearman correlation analysis,the ICU stay and hospital stay may be positively correlated with operative time,anhepatic phase time and intraoperative blood loss.There were no differences in the incidence of postoperative complications,readmissions,and postoperative mortality between the two groups.CONCLUSION:Fast-track procedures effectively reduce the ICU stay and hospital stay without adversely affecting prognosis.This study demonstrated that fast-track protocols are safe and feasible in liver transplantation.Jian-Hua Rao Feng Zhang Hao Lu Xin-Zheng Dai Chuan-Yong Zhang Xiao-Feng Qian Xue-Hao Wang Ling Lu 2017Hepatobiliary & Pancreatic Diseases International2017,16,4:23

20A STUDY ON NUMERICAL METHOD OF NAVIER-STOKES EQUATION AND NON-LINEAR EVOLUTION OF THE COHERENT STRUCTURES IN A LAMINAR BOUNDARY LAYER显示文摘A new method for direct numerical simulation of incompressible Navier-Stokes equations is studied in the paper. The compact finite difference and the non-linear terms upwind compact finite difference schemes on non-uniform meshes in x and y directions are developed respectively. With the Fourier spectral expansion in the spanwise direction, three-dimensional N-S equation are converted to a system of two-dimensional equations. The third-order mixed explicit-implicit scheme is employed for time integration. The treatment of the three-dimensional non-reflecting outflow boundary conditions is presented, which is important for the numerical simulations of the problem of transition in boundary layers, jets, and mixing layer. The numerical results indicate that high accuracy, stabilization and efficiency are achieved by the proposed numerical method. In addition, a theory model for the coherent structure in a laminar boundary layer is also proposed, based on which the numerical method is implemented to the non-linear evolution of coherent structure. It is found that the numerical results of the distribution of Reynolds stress, the formation of high shear layer, and the event of ejection and sweeping, match well with the observed characteristics of the coherent structures in a turbulence boundary layer.LU Chang-gen CAO Wei-dong QIAN Jian-hua 2006Journal of Hydrodynamics2006,18,3:21
