Based on the high sulfur content in titanium gypsum,the concept of the calcium-silicon-sulfur(Ca/Si/S)ratio was proposed.The Ca/Si/S ratio of concrete was adjusted by changing the titanium gypsum,fly ash,and cement con-tent.The effects of different Ca/Si/S ratios on the mechanical properties,hydration products,and concrete micro-structure were investigated by nuclear magnetic resonance,uniaxial compression,and scanning electron microscopy.The result shows:(1)The compressive strength of concrete mixed with titanium gypsum increases first and then decreases with the Ca/Si/S ratio decrease.When the Ca/Si/S ratio is 1:0.85:0.10,the strength reaches the peak and is lower than the blank group.(2)The microstructure indicates the addition of titanium gypsum can effectively stimulate the activity of fly ash.Still,too much or too little titanium gypsum will hamper concrete strength development.(3)Titanium gypsum concrete’s nuclear magnetic resonance T2 spectrum has two characteristic peaks.With the Ca/Si/S ratio decreasing,the micropores in the concrete expand towards the macropores.The compressive strength is negatively correlated with the proportion of macropores and is positively correlated with the proportion of no-capillary pores. 展开更多

Objective:This randomized study aimed to compare the clinical efficacy between the novel dual tracer composed of indocyanine green(ICG)and blue dye(BD)and the conventional dual tracer composed of radioisotope and BD for sentinel lymph node(SLN)mapping in patients with breast cancer.Methods:This study enrolled 471 clinically lymph node-negative patients with primary breast cancer.All patients underwent mastectomy,and those undergoing sentinel lymph node biopsy(SLNB)were randomized to receive blue dye plus radioisotope(RB group)or BD plus ICG(IB group).The detection performances on SLN identification rate,positive SLN counts,detection sensitivity,and false-negative rate were compared between the two groups.Results:In the IB group,97%(194/200)of the patients who underwent the ICG and BD dual tracer injection showed fluorescentpositive lymphatic vessels within 2–5 min.The identification rate of SLNs was comparable between the IB group(99.0%,198/200)and the RB group(99.6%,270/271)(P=0.79).No significant differences were observed in the identification rate of metastatic SLNs(22.5%vs.22.9%,P>0.05,RB group vs.IB group,the same below),positive SLN counts(3.72±2.28 vs.3.91±2.13,P>0.05),positive metastatic SLN counts(0.38±0.84 vs.0.34±0.78,P>0.05),SLNB detection sensitivity(94.4%vs.92.5%,P>0.05),or false-negative rate(5.6%vs.7.5%,P>0.05)between the two groups.Conclusions:ICG can be used as a promising alternative tracer for radioisotope in SLN mapping,and when it is combined with BD in lymphangiography,it offers comparable detection sensitivity compared to the conventional lymphatic mapping strategies that are widely used in clinical practice. 展开更多

A model of evolution induced catastrophe(EIC)characterized by a nonlocal interaction is proposed.The general feature of the model is its two bias states:explosively catastrophic and globally stable,both consisting in a cascade of locally unstable states.A one-dimensional analysis reveals a transition region from globally stable to catastrophe.A two-dimensional simulation gives a thin fractal fracture profile similar to that observed and also a possible spectrum of fracture fractal.All these are different from percolation.Hence,the EIC model may represent a prototype of natural processes. 展开更多

BACKGROUND Dieulafoy's lesion is a rare vascular abnormality characterized by a small abnormally dilated artery that runs a tortuous course in the submucosa.There is usually no ulcer present in Dieulafoy's lesions and the overlying mucosa is most often normal.Bleeding caused by a Dieulafoy's lesion is usually urgent,massive,life-threatening and prone to recurrence.Dieulafoy's lesions have been reported throughout the digestive tract although the majority of them have been found in the upper digestive tract especially the stomach and duodenum.However,a Dieulafoy's lesion occurring inside a duodenal diverticulum is very rare.CASE SUMMARY A 74-year-old Asian male with epigastric pain,hematemesis and melena was admitted to our clinic.Before admission,the patient had vomited 500 m L of dark red blood,and passed 200 g of black tarry stool.Conservative management was first undertaken as the patient had not been fasting.However,hemorrhage recurred and the patient went into shock.Urgent endoscopy was performed and a diverticulum of 1.8 cm×1.2 cm×0.8 cm was found on the anterior wall of the descending duodenum.The diverticulum was covered with a blood clot.After the clot was removed,an artery stump was observed in the diverticulum with a diameter of 2-3 mm.Two titanium hemostatic clips were inserted to clamp the vessel stump.The patient was discharged 7 d post-endoscopy and followed for 6 mo with no recurrence.CONCLUSION This case was diagnosed with a Dieulafoy's lesion inside a duodenal diverticulum which has rarely been reported.Hematemesis was stopped by clamping the vessel stump with titanium clips.No complications occurred. 展开更多

A three-dimensional finite element program for thermal analysis of hydration heat in concrete structures with a plastic pipe cooling system is introduced in this paper. The program was applied to simulation of the temperature and stress field of the Cao'e Sluice during the construction period. From the calculated results, we can find that the temperaiure and stress of concrete cooled with plastic pipes are much lower than those of concrete without pipes. Moreover, plastic pipes could not be corroded by seawater. That is to say, a good effect of temperature control and cracking prevention can be achieved, which provides a useful reference for other similar nearshore concrete projects. 展开更多

Background: The goal is to determine the incidence of symptomatic gastrointestinal (GI) injuries in acute coronary syndrome (ACS) patients receiving double antiplatelet therapy (DAPT). The risk factors for serious GI complications are also evaluated. Methods: 603 eligible patients from the Department of Cardiology at Zhongda Hospital between January 2014 and August 2015 were enrolled and the occurrence of GI injuries within one year assessed. The risk factors for serious GI complications were identified using cox regression analysis. Results: After one-year follow-up, 108 (17.9%) out of 603 patients developed symptomatic GI injuries: 22 (3.65%) with serious GI complications and 86 (14.2%) with GI symptoms. Drinking habit (95% CI: 1.512 - 8.796;P = 0.004) and previous peptic injury (95% CI: 2.307 - 18.080;P = 0.001) are independent predictors of serious GI complications, while proton pump inhibitor (PPI) was protective (95% CI: 0.120 - 0.699;P = 0.006) per cox regression analysis. Additionally, GI injuries of both serious GI complications and GI symptoms peaked in the first three months. Conclusions: Symptomatic GI injuries were relatively common in ACS patients with DAPT, especially in the first three months. Previous peptic injury and drinking habit were significant independent risk factors for serious GI complications, while PPI played a protective role in ACS with DAPT. 展开更多

The human retina serves as a light detector and signals transmission tissue.Advanced insights into retinal disease mechanisms and therapeutic strategies require a deep understanding of healthy retina molecular events.Here,we sequenced the m RNA of over 0.6 million single cells from human retinas across six regions at nine different ages.Sixty cell sub-types have been identified from the human mature retinas with unique markers.We revealed regional and age differences of gene expression profiles within the human retina.Cell-cell interaction analysis indicated a rich synaptic connection within the retinal cells.Gene expression regulon analysis revealed the specific expression of transcription factors and their regulated genes in human retina cell types.Some of the gene’s expression,such as DKK3,are elevated in aged retinas.A further functional investigation suggested that over expression of DKK3 could impact mitochondrial stability.Overall,decoding the molecular dynamic architecture of the human retina improves our understanding of the vision system. 展开更多

The 2019 coronavirus disease(COVID-19)outbreak caused by the SARS-CoV-2 virus is an ongoing global health emergency.However,the virus'pathogenesis remains unclear,and there is no cure for the disease.We investigated the dynamic changes of blood immune response in patients with COVID-19 at different stages by using 5'gene expression,T cell receptor(TCR),and B cell receptors(BCR)V(D)J transcriptome analysis at a single-cell resolution.We obtained single-cell mRNA sequencing(scRNA-seq)data of 341,420 peripheral blood mononuclear cells(PBMCs)and 185,430 donotypic T cells and 28,802 donotypic B cells from 25 samples of 16 patients with COVID-19 for dynamic studies.In addition,we used three control samples.We found expansion of dendritic cells(DCs),CD14+monocytes,and megakaryocytes progenitor cells(MP)/platelets and a reduction of naive CD4+T lymphocytes in patients with COVID-19,along with a significant decrease of CD8+T lymphocytes,and natural killer cells(NKs)in patients in critical condition.The type I interferon(IFN-I),mitogen-activated protein kinase(MAPK),and ferroptosis pathways were activated while the disease was active,and recovered gradually after patient conditions improved.Consistent with this finding,the mRNA level of IFN-I signal-induced gene IFI27 was significantly increased in patients with COVID-19 compared with that of the controls in a validation cohort that included 38 patients and 35 controls.The concentration of interferon-a(IFN-a)in the serum of patients with COVID-19 increased significantly compared with that of the controls in an additional cohort of 215 patients with COVID-19 and 106 controls,further suggesting the important role of the IFN-I pathway in the immune response of COVID-19.TCR and BCR sequences analyses indicated that patients with COVID-19 developed specific immune responses against SARS-CoV-2 antigens.Our study reveals a dynamic landscape of human blood immune responses to SARS-CoV-2 infection,providing clues for therapeutic potentials in treating COVID-19. 展开更多

Intraocular pressure(IOP) is a major risk factor for glaucoma. Genetic determinants of intraocular pressure can provide critical insights into the genetic architecture of glaucoma and, as a result, open new avenues for therapeutic intervention. We performed a genome-wide association study and replication analysis of 8,552 Chinese participants. In the genome-wide association study, we identified 51 loci that surpassed the significance of P<9×10^(-7), and we formally replicated these loci. A combined discovery and replication meta-analysis identified 21 genome-wide loci that surpassed the genome-wide significance of P<5×10^(-8), including 4 previously reported loci: rs145063132(7 p21.2, ETV1/DGKB), rs548030386(7 q31.2, ST7 near CAV1/CAV2), rs7047871(9 p24.2, GLIS3), and rs2472494(9 q31.1, ABCA1/SLC44 A1). Of the 17 newly identified loci, five were reported to have ocular related phenotypes: PTCH2(rs7525308 in 1 p34.1), LRIF1/DRAM2(rs1282146 in 1 p13.3), COLEC11(rs201143466 in 2 p25.3),SPTBN1(rs4514918 in 2 p16.2), and CRK(rs11078446 in 17 p13.3). The genetic loci identified in this study not only increase our understanding of the genes involved in intraocular pressure but also provide important genetic markers to improve future genetic screening and drug discovery for intraocular pressure disorders. 展开更多

Background:Erythropoietin is a glycoprotein that mainly regulates erythropoiesis.In patients with chronic renal failure with anemia,darbepoetin alfa can stimulate erythropoiesis,correct anemia,and maintain hemoglobin levels.This study was designed to demonstrate the efficacy and safety of darbepoetin alfa injections as being not inferior to epoetin alfa injections(Recombinant Human Erythropoietin injection,rHuEPO)when maintaining hemoglobin(Hb)levels within the target range(10.0-12.0 g/dL)for the treatment of renal anemia.Methods:Ninety-five patients were enrolled in this study from April 15,2013 to April 10,2014 at 25 sites.In this study,patients(n=95)aged 18-70 years were randomized into a once per week intravenous darbepoetin alfa group(n=56)and a twice or three times per week intravenous epoetin alfa group(n=39)for 28 weeks,who had anemia with hemoglobin levels between 6 g/dL and 10 g/dL due to chronic kidney disease(CKD)and were undergoing hemodialysis or hemofiltration with ESA-naive(erythropoiesis stimulating agent-naive).The primary efficacy profile was the mean Hb level(the non-inferiority margin was-1.0 g/dL,week 21-28);the secondary efficacy profiles were the Hb increase rate(week 0-4),the target Hb achievement cumulative rate and time,the change trends of the Hb levels,and the target Hb maintenance ratio.Adverse events(AEs)were observed and compared,and the efficacy and safety were analyzed between the two treatment groups.Additionally,the frequencies of dose adjustments between the darbepoetin alfa and epoetin alfa groups were compared during the treatment period.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:The mean Hb level was 11.3 g/dL in the darbepoetin alfa group and 10.7 g/dL in the epoetin alfa group,respectively;the difference of the lower limits of the 95%confidence intervals(CI)between the two groups was 0.1 g/dL(>-1.0 g/dL),and non-inferiority was proven;the Hb levels started to increase in the first four weeks at a similar increase rate;no obvious differences were observed between the groups in the target Hb achievement cumulative rates,and the Hb levels as well as the target Hb level maintenance rate changed over time.The incidence of AEs was 62.5%in the darbepoetin alfa group and 76.9%in the epoetin alfa group.All the adverse events observed in the study were those commonly associated with hemodialysis.Conclusion:Darbepoetin alfa intravenously once per week can effectively increase Hb levels and maintain the target Hb levels well,which makes it not inferior to epoetin alfa intravenously twice or three times per week.Darbepoetin alfa shows an efficacy and safety comparable to epoetin alfa for the treatment of renal anemia. 展开更多

Background:This study was to explore the clinical efficacy and safety of darbepoetin alfa injection replacing epoetin alfa injection(recombinant human erythropoietin injection,rHuEPO)for the treatment of anemia associated with chronic kidney failure in Chinese patients undergoing hemodialysis.Method:This study was a multicenter,randomized,open-label,intergroup parallel control phase III noninferiority trial from April 19,2013 to September 9,2014 at 25 sites.In this study,the members of the darbepoetin alfa group underwent intravenous administration once per week or once every two weeks.The members of the control drug epoetin alfa group underwent intravenous administration two or three times per week.All subjects underwent epoetin alfa administration during the 8-week baseline period.After that,subjects were randomly assigned to the darbepoetin alfa group or epoetin alfa group.The noninferiority in the changes of the average Hb concentrations from the baseline to the end of the evaluation period(noninferiority threshold:-1.0 g/dl)was tested between the two treatments.The time-dependent hemoglobin(Hb)concentration and the maintenance rate of the target Hb concentration(the proportion of subjects with Hb concentrations between 10.0 and 12.0 g/dl)were also evaluated.Iron metabolism,including changes in the serum iron,total iron-binding capacity,ferritin,transferrin saturation,and comparisons of the dose adjustments between the two groups during the treatment period were analyzed further.Adverse events(AEs)were also observed and compared,and the safety was analyzed between the two treatment groups.The conversion rate switching from epoetin alfa to darbepoetin alfa was also discussed.SAS?software version 9.2 was used to perform all statistical analyses.Descriptive statistics were used for all efficacy,safety,and demographic variable analyses,including for the primary efficacy indicators.Results:Four hundred and sixty-six patients were enrolled in this study,and ultimately 384 cases were analyzed for safety,including 267 cases in the darbepoetin alfa group and 117 cases in the epoetin alfa group.There were 211 cases in the per-protocol set,including 152 cases in the darbepoetin alfa group and 59 cases in the epoetin alfa group.The changes in the average Hb concentrations from the baseline to the end of the evaluation period were-0.07 and-0.15 g/dl in the darbepoetin alfa group and epoetin alfa group respectively.The difference between the two groups was 0.08 g/dl(95%confidence interval[CI]:-0.22 to 0.39),and the lower limit of the 95%CI was-0.22>-1.0 g/dl.The average Hb concentrations of the two groups were 10.88-11.43 g/dl(darbepoetin alfa)and 10.91-11.38 g/dl(epoetin alfa)during the study period of Weeks 0-28,with the maintenance rates of the target Hb concentration ranging within 71%-87%and 78%-95%in the darbepoetin alfa group and epoetin alfa group respectively.During the period of comparison between the two groups,the incidence of AEs in the darbepoetin alfa group was 61.42%,while in the epoetin alfa group it was 56.41%.All of the adverse events and reactions in the study were those commonly associated with hemodialysis.Conclusion:The overall efficacy and safety of darbepoetin alfa for the treatment of Chinese renal anemia patients undergoing hemodialysis are consistent with those of epoetin alfa. 展开更多

Recently non-coding RNA (ncRNA) genes have been found to serve many important functions in the cell such as regulation of gene expression at the transcriptional level. Potentially there are more ncRNA molecules yet to be found and their possible functions are to be revealed. The discovery of ncRNAs is a difficult task because they lack sequence indicators such as the start and stop codons dis- played by protein-coding RNAs. Current methods utilize either sequence motifs or structural parameters to detect novel ncRNAs within genomes. Here, we present an ab initio ncRNA finder, named ncRNAscout, by utilizing both sequence motifs and structural parameters. Specifically, our method has three components: (i) a measure of the frequency of a sequence, (ii) a measure of the structural stability of a sequence contained in a t-score, and (iii) a measure of the frequency of certain patterns within a sequence that may indicate the presence of ncRNA. Experimental results show that, given a genome and a set of known ncRNAs, our method is able to accurately identify and locate a significant number of ncRNA sequences in the genome. The ncRNAscout tool is available for downloading at http:/]bioinfor- matics.njit.edu/ncRNAscout. 展开更多

The Revised International Staging System(R-ISS)is a simple and powerful prognostic tool for multiple myeloma(MM).However,heterogeneity in R-ISS stage is still poorly characterised,hampering improvement of treatments.We used single-cell RNA-seq to examine novel cellular heterogeneity and regular networks in nine MM patients stratified by R-ISS.Plasma cells were clustered into nine groups(P1–P9)based on gene expression,where P1–P5 were almost enriched in stage III.PDIA6 was significantly upregulated in P3 and LETM1was enriched in P1,and they were validated to be upregulated in the MM cell line and in 22 other patients’myeloma cells.Furthermore,in progression,PDIA6 was newly found and verified to be activated by UQCRB through oxidative phosphorylation,while LETM1 was activated by STAT1 via the C-type lectin receptor-signalling pathway.Finally,a subcluster of monocytes was exclusively found in stage III specifically expressed chemokines modulated by ATF3.A few ligand-receptor pairs(CCL3/CCL5/CCL3L1-CCR1)were obviously active in monocyte-plasma communications in stage III.Herein,this study identified novel molecules,networks and crosstalk pairs in different R-ISS stages of MM,providing significant insight for its prognosis and treatment. 展开更多

Critical coronavirus disease 2019(COVID-19)is associated with high mortality and potential genetic factors have been reported to be involved in the development of critical COVID-19.We performed a genome-wide association study to identify the genetic factors responsible for developing critical COVID-19.632 critical patients with COVID-19 and 3021 healthy controls from the Chinese population were recruited.First,we identified a genome-wide significant difference of IL-6 rs2069837(p=9.73×10^(−15),OR=0.41)between 437 critical patients with COVID-19 and 2551 normal controls in the discovery cohort. 展开更多
