1Differences in symptoms and pre-hospital delay among acute myocardial infarction patients according to ST-segment elevation on electrocardiogram: an analysis of China Acute Myocardial Infarction (CAMI) registry显示文摘Background: Approximately 70% patients with acute myocardial infarction (AMI) presented without ST-segment elevation on electrocardiogram. Patients with non-ST segment elevation myocardial infarction (NSTEMI) often presented with atypical symptoms, which may be related to pre-hospital delay and increased risk of mortality. However, up to date few studies reported detailed symptomatology of NSTEMI, particularly among Asian patients. The objective of this study was to describe and compare symptoms and presenting characteristics of NSTEMI vs. STEMI patients. Methods: We enrolled 21,994 patients diagnosed with AMI from China Acute Myocardial Infarction (CAMI) Registry between January 2013 and September 2014. Patients were divided into 2 groups according to ST-segment elevation: ST-segment elevation (STEMI) group and NSTEMI group. We extracted data on patients' characteristics and detailed symptomatology and compared these variables between two groups. Results: Compared with patients with STEMI (N=16,315), those with NSTEMI (N=5679) were older, more often females and more often have comorbidities. Patients with NSTEMI were less likely to present with persistent chest pain (54.3% vs.71.4%), diaphoresis (48.6% vs.70.0%), radiation pain (26.4% vs.33.8%), and more likely to have chest distress (42.4% vs.38.3%) than STEMI patients (all P<0.0001). Patients with NSTEMI were also had longer time to hospital. In multivariable analysis, NSTEMI was independent predictor of presentation without chest pain (odds ratio: 1.974, 95% confidence interval:1.849-2.107). Conclusions: Patients with NSTEMI were more likely to present with chest distress and pre-hospital patient delay compared with patients with STEMI. It is necessary for both clinicians and patients to learn more about atypical symptoms of NSTEMI in order to rapidly recognize myocardial infarction.Rui Fu Chen-Xi Song Ke-Fei Dou Jin-Gang Yang Hai-Yan Xu Xiao-Jin Gao Qian-Qian Liu Han Xu Yue-Jin Yang 2019Chinese Medical Journal2019,,5:29
2Effect of Bcl-2 and Bax on survival of side population cells from hepatocellular carcinoma cells显示文摘AIM: To understand the role and significance of side population (SP) cells from hepatocellular carcinoma (HCC) in hepatocarcinogenesis, development, relapse and metastasis, we simulated the denutrition conditions that cancer cells experience in clinical therapy, observed the different anti-apoptosis ability of SP cells and non-SP cells under such conditions, and established the possible effects of P53, Bcl-2 and Bax on survival of SP cells. METHODS: We used ? ow cytometry to analyze and sort the SP and non-SP cells in established HCC lines MHCC97 and hHCC. We evaluated cell proliferation by methyl thiazolyl tetrazolium (MTT) assay and investigated the expression of p53, bcl-2 and bax genes during denutrition, by RT-PCR and immuno? uorescence staining. RESULTS: The percentage of SP cells in the two established HCC lines was 0.25% and 0.5%, respectively. SP cells had greater anti-apoptosis and proliferation ability than non-SP cells. Expression of Bcl-2 and Bax in SP and non-SP cells differed during denutrition. The former was up-regulated in SP cells, and the latter was up-regulated in non-SP cells. CONCLUSION: It may be that different upstream molecules acted and led to different expression levels of Bcl-2 and Bax in these two cell lines. There was a direct relationship between up-regulation of Bcl-2 and down-regulation of Bax and higher anti-apoptosis ability in SP cells. It may be that the existence and activity of SP cells are partly responsible for some of the clinical phenomena which are seen in HCC, such as relapse or metastasis. Further research on SP cells may have potential applications in the f ield of anticancer therapy.Jing Fan Ren Li Rui Zhang Hai-Liang Liu Ning Zhang Fu-Qing Zhang Ke-Feng Dou 2007World Journal of Gastroenterology2007,13,45:27
3Clinical significance of diabetes on symptom and patient delay among patients with acute myocardial infarction——an analysis from China Acute Myocardial Infarction(CAMI) registry显示文摘Background Diabetes is frequently associated with poor prognosis among acute myocardial infarction(AMI)patients.Patients with these comorbidities often have atypical symptoms and subsequent delay in treatment.Few studies have reported detailed AMI symptoms in patients with diabetes.This study compared AMI symptoms and presentation characteristics between diabetics and non-diabetics.Methods We included patients from the China AMI registry diagnosed with AMI between January 2013 and September 2014.Baseline characteristics,symptomology,and delay in treatment were compared between diabetics and non-diabetics.Multivariable logistic regression analysis was used to explore independent predictors of atypical symptoms.Results A total of 4450(20.2%)patients had diabetes.They were older,more often women,higher in body mass index,and more likely to have non-ST segment elevation myocardial infarction.Fewer diabetic patients presented with persistent precordial chest pain(63.1%vs.68%,P<0.0001),diaphoresis(60.1%vs.65.6%,P<0.0001),fatigue(16.7%vs.18.3%,P=0.0123),and incontinence(0.4%vs.0.7%,P=0.0093).Time to hospital presentation was longer among patients with diabetes than those without.In multivariable analysis,diabetes was identified as an independent predictor of atypical symptoms(OR:1.112,95%CI:1.034?1.196).Conclusions Our study is the first large-scale study providing evidence that diabetics are less likely to present with typical chest pain and more likely to experience treatment delay when suffering from an AMI.Our results may increase clinician awareness of recognizing AMI patients rapidly to reduce diagnosis and treatment delay,particularly in the context of diabetes.Rui FU Si-Dong LI Chen-Xi SONG Jing-Ang YANG Hai-Yan XU Xiao-Jin GAO Yi XU Jian-Ping ZENG Jun-Nong LI Ke-Fei DOU Yue-Jin YANG on behalf of the CAMI Registry study group Beijing,China 2019Journal of Geriatric Cardiology2019,16,5:21
4Effects of Tongxinluo-facilitated cellular cardiomyoplasty with autologous bone marrow-mesenchymal stem cells on postinfarct swine hearts显示文摘<正> Background Treatment of ischemic heart disease remains an important challenge,though there have been enormousprogresses in cardiovascular therapeutics.This study was conducted to evaluate whether Tongxinluo(TXL)treatmentaround the transplantation of mesenchymal stem cells(MSCs)can improve survival and subsequent activities ofimplanted cells in swine hearts with acute myocardial infarction(AMI)and reperfusion.Methods Twenty-eight Chinese mini-pigs were divided into four groups including a control group(n=7);group 2,administration of low-dose TXL alone from the 3rd day prior to AMI to the 4th day post transplantation(n=7);group 3,MSCs alone(n=7)and group 4,TXL+MSCs(n=7).AMI models were made by occlusion of the left anterior descendingcoronary artery for 90 minutes.Autologous bone marrow-MSCs(3×10~7 cells/animal)were then injected into thepost-infarct myocardium immediately after AMI and reperfusion.The survival and differentiation of implanted cells in vivowere detected by immunofluorescent analysis.The data of cardiac function were obtained at baseline(1 week aftertransplantation)and endpoint(6 weeks after transplantation)by single photon emission computed tomography(SPECT)and magnetic resonance imaging(MRI).Apoptosis was detected by TUNEL assay and the oxidative stress level wasinvestigated in the post-infarct myocardium at endpoint.Results At endpoint,there was less fibrosis and inflammatory cell infiltration with more surviving myocardium in group 4than in the control group.In group 4 the survival and differentiation of implanted MSCs were significantly improved morethan that seen in group 3 alone(P<0.0001);the capillary density was also significantly greater than in the control group,group 2 or 3 both in the infarcted zone(P<0.0001)and the peri-infarct zone(P<0.0001).MRI showed that parameters atbaseline were not significantly different between the 4 groups.At endpoint,regional wall thickening and the left ventricularejection fraction were increased while the left ventricular mass index,dyskinetic segments and infarcted size weredecreased only in group 4 compared with control group(P<0.0001).SPECT showed that the area of perfusion defectwas significantly decreased at endpoint only in group 4 compared with control group(P<0.0001).TUNEL assay indicatedthat TXL administration significantly decreased cell apoptosis in peri-infarct myocardium in groups 2 and 4.Furthermore,superoxide dismutase(SOD)significantly increased and malondialdehyde(MDA)decreased in groups 2 and 4 by theadministration of TXL.Conclusions Our study demonstrates the following:(1)immediate intramyocardial injection of MSCs after AMI andreperfusion resulted in limited survival and differentiation potential of implanted cells in vivo,thus being incapable ofbeneficially affecting post-hearts;(2)TXL-facilitation resulted in a significant survival and differentiation potential ofimplanted cells in vivo via inhibition of apoptosis and oxidative stress,accompanied by significant benefits in cardiacfunction.Chin Med J 2007;120(16)QIAN Hai-yan YANG Yue-jin HUANG Ji GAO Run-lin DOU Ke-fei YANG Guo-sheng LI Jian-jun SHEN Rui HE Zuo-xiang LU Min-jie ZHAO Shi-hua 2007Chinese Medical Journal2007,,16:19
5Are humic substances soil microbial residues or unique synthesized compounds?A perspective on their distinctiveness显示文摘Humic substances(HS),which are defined as a series of highly acidic,relatively high-molecular-weight,and yellow to black colored substances formed during the decay and transformation of plant and microbial remains,ubiquitously occur in nature.Humic substances represent the largest stable organic carbon pool in terrestrial environments and are the central characteristic of the soil.However,the validity of the HS concept and the justification of their extraction procedure have been recently debated.Here,we argue that the traditional humic paradigm is still relevant.Humic substances are distinctive and complex because the extracted HS formed during the humification are chemically distinct from their precursors and are heterogeneous among soils.By reviewing the concept,formation pathways,and stabilization of HS,we propose that the key question facing soil scientists is whether HS are soil microbial residues or unique synthesized compounds.Without revealing the distinctiveness of HS,it is impossible to address this question,as the structure,composition,and reactivity of HS are still poorly known owing to the heterogeneity and geographical variability of HS and the limits of the currently available analytical techniques.In our view,the distinctiveness of HS is fundamental to the soil,and thus further studies should be focused on revealing the distinctiveness of HS and explaining why HS hold this distinctiveness.Sen DOU Jun SHAN Xiangyun SONG Rui CAO Meng WU Chenglin LI Song GUAN 2020Pedosphere2020,30,2:12
6Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite.Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie 2021Cell Research2021,31,7:12

8Angiographic characteristics and in-hospital mortality among patients with ST-segment elevation myocardial infarction presenting without typical chest pain: an analysis of China Acute Myocardial Infarction registry显示文摘Background:Patients with ST-segment elevation myocardial infarction(STEMI)who present without typical chest pain are associated with a poor outcome.However,whether angiographic characteristics are related to a higher risk of mortality in this population is unclear.This study aimed to investigate whether the higher mortality risk in patients with STEMI without chest pain could be explained by their'high-risk'angiographic characteristics.Methods:We used data of 12,145 patients with STEMI who was registered in China Acute Myocardial Infarction registry from January 2013 to September 2014.We compared the infarct-related artery(IRA),thrombolysis in myocardial infarction(TIMI)flow grade in the IRA,and other angiographic characteristics between patients without and those with chest pain.Multivariable logistic regression model was used to identify independent risk factor of in-hospital mortality.Results:The 2922(24.1%)patients with STEMI presented without typical chest pain.These patients had a higher TIMI flow grade(mean TIMI flow grade:1.00 vs.0.94,P=0.02)and a lower rate of IRA disease of the left anterior descending artery(44.6%vs.51.2%,χ^2=35.63,P<0.01)than did those with typical chest pain.Patients without chest pain were older,more likely to have diabetes,longer time to hospital and higher Killip classification,and less likely to receive optimal medication treatment and primary percutaneous coronary intervention and higher In-hospital mortality(3.3%vs.2.2%,χ^2=10.57,P<0.01).After adjusting for multi-variables,presentation without chest pain was still an independent predictor of in-hospital death among patients with STEMI(adjusted odds ratio:1.36,95%confidence interval:1.02–1.83).Conclusions:Presentation without chest pain is common and associated with a higher in-hospital mortality risk in patients with acute myocardial infarction.Our results indicate that their poor prognosis is associated with baseline patient characteristics and delayed treatment,but not angiographic lesion characteristics.Clinical trial registration:NCT01874691,http://gffzzd3f38a9638994581sk5q5kox6u56066pk.ffgz.tsg.suse.edu.cn.Chen-Xi Song Rui Fu Jin-Gang Yang Hai-Yan Xu Xiao-Jin Gao Chun-Yue Wang Yang Zheng Shao-Bin Jia Ke-Fei Dou Yue-Jin Yang on behalf of the CAMI Registry study group 2019Chinese Medical Journal2019,,19:11

10The resurgent landscape of xenotransplantation of pig organs in nonhuman primates显示文摘Organ shortage is a major bottleneck in allotransplantation and causes many wait-listed patients to die or become too sick for transplantation.Genetically engineered pigs have been discussed as a potential alternative to allogeneic donor organs.Although xenotransplantation of pig-derived organs in nonhuman primates(NHPs)has shown sequential advances in recent years,there are still underlying problems that need to be completely addressed before clinical applications,including(i)acute humoral xenograft rejection;(ii)acute cellular rejection;(iii)dysregulation of coagulation and inflammation;(iv)physiological incompatibility;and(v)cross-species infection.Moreover,various genetic modifications to the pig donor need to be fully characterized,with the aim of identifying the ideal transgene combination for upcoming clinical trials.In addition,suitable pretransplant screening methods need to be confirmed for optimal donor-recipient matching,ensuring a good outcome from xenotransplantation.Herein,we summarize the understanding of organ xenotransplantation in pigs-to-NHPs and highlight the current status and recent progress in extending the survival time of pig xenografts and recipients.We also discuss practical strategies for overcoming the obstacles to xenotransplantation mentioned above to further advance transplantation of pig organs in the clinic.Xuan Zhang Quancheng Wang Jingjun Zhao Xiao Li Wei Peng Zhaoxu Yang Zhibin Lin Long Yang Rui Ding Kaishan Tao Kefeng Dou 2021Science China(Life Sciences)2021,64,5:10
11A dual timescale model for micro-mixing and its application in LES-TPDF simulations of turbulent nonpremixed flames显示文摘The numerical simulation of modern aero-engine combustion chamber needs accurate description of the interaction between turbulence and chemical reaction mechanism. The Large Eddy Simulation(LES) method with the Transported Probability Density Function(TPDF) turbulence combustion model is promising in engineering applications. In flame region, the impact of chemical reaction should be considered in TPDF molecular mixing model. Based on pioneer research, three new TPDF turbulence-chemistry dual time scale molecular mixing models were proposed tentatively by adding the chemistry time scale in molecular mixing model for nonpremixed flame. The Aero-Engine Combustor Simulation Code(AECSC) which is based on LES-TPDF method was combined with the three new models. Then the Sandia laboratory's methane-air jet flames: Flame D and Flame E were simulated. Transient simulation results show that all the three new models can predict the instantaneous combustion flow pattern of the jet flames. Furthermore,the average scalar statistical results were compared with the experimental data. The simulation result of the new TPDF arithmetic mean modification model is the closest to the experimental data:the average error in Flame D is 7.6% and 6.6% in Flame E. The extinction and re-ignition phenomena of the jet flames especially Flame E were captured. The turbulence time scale and the chemistry time scale are in different order in the whole flow field. The dual time scale TPDF combustion model has ability to deal with both the turbulence effect and the chemistry reaction effect, as well as their interaction more accurately for nonpremixed flames.Fang WANG Rui LIU Li DOU Denghuan LIU Jie JIN 2019Chinese Journal of Aeronautics2019,32,4:9
12Effect of a poloxamer 407-based thermosensitive gel on minimization of thermal injury to diaphragm during microwave ablation of the liver显示文摘AIM To assess the insulating effect of a poloxamer 407(P407)-based gel during microwave ablation of liver adjacent to the diaphragm.METHODS We prepared serial dilutions of P407, and 22.5%(w/w) concentration was identified as suitable for ablation procedures. Subsequently, microwave ablations were performed on the livers of 24 rabbits(gel, saline, control groups, n = 8 in each). The P407 solution and 0.9% normal saline were injected into the potential space between the diaphragm and liver in experimental groups. No barriers were applied to the controls. After microwave ablations, the frequency, size and degree of thermal injury were compared histologically among the three groups. Subsequently, another 8 rabbits were injected with the P407 solution and microwave ablation was performed. The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood urea nitrogen(BUN) and creatinine(Cr) in serum were tested at 1 d before microwave ablation and 3 and 7 d after operation. RESULTS In vivo ablation thermal injury to the adjacent diaphragm was evaluated in the control, saline and 22.5% P407 gel groups(P = 0.001-0.040). However, there was no significant difference in the volume of ablation zone among the three groups(P > 0.05). Moreover, there were no statistical differences among the preoperative and postoperative gel groups according to the levels of ALT, AST, BUN and Cr in serum(all P > 0.05).CONCLUSION Twenty-two point five percent P407 gel could be a more effective choice during microwave ablation of hepatic tumors adjacent to the diaphragm. Further studies for clinical translation are warranted.Li-Li Zhang Gui-Min Xia Yu-Jiang Liu Rui Dou John Eisenbrey Ji-Bin Liu Xiao-Wei Wang Lin-Xue Qian 2017World Journal of Gastroenterology2017,23,12:6
13Modification of Mn on corrosion and mechanical behavior of biodegradable Mg(88)Y4Zn2Li5 alloy with long-period stacking ordered structure显示文摘The biological corrosion behavior and mechanical properties of Mg(89-x)Y4 Zn2 Li5 Mnx(x=0,0.5,1,1.5 and2 at.%) alloy with long-period stacking ordered(LPSO) structure were investigated in this work.The magnesium matrix and the eutectic phase of Mg(88)Y4 Zn2 Li5 Mn1 alloy are effectively refined by the grain boundary segregation of Mn,and the average size of matrix and the eutectic phase decreased by 66%and 74%,respectively.The ultimate tensile strength(UTS) and elongation enhanced by 36% and 55%,respectively.The corrosion rates obtained by weight loss and hydrogen evolution of Mg(88)Y4 Zn2 Li5 Mn1 alloy were 79% and 84% lower than that of Mg(88)Y4 Zn2 Li5 alloy.Additionally,Mg(88)Y4 Zn2 Li5 Mn1 alloy also presents superior corrosion behavior in electrochemical test.It is verified that Mn plays a positive role in both corrosion and mechanical properties of the Mg(88)Y4 Zn2 Li5 Mn1 alloy,which provides a reference for further experimental work.Jiaxin Zhang Jinshan Zhang Fuyin Han Wei Liu Longlong Zhang Rui Zhao Chunxiang Xu Jing Dou 2020Journal of Materials Science & Technology2020,42,7:4
14Cholecystectomy is associated with higher risk of recurrence after microwave ablation of hepatocellular carcinoma:a propensity score matching analysis显示文摘Objective:To explore the association between cholecystectomy and the prognostic outcomes of patients with hepatocellular carcinoma(H CC)who underwent microwave ablation(MWA).Methods:Patients with HCC(«=921)who underwent MWA were included and divided into cholecystectomy(n=114)and non-cholecystectomy groups(n=807).After propensity score matching(PSM)at a 1:2 ratio,overall survival(OS)and disease-free survival(DFS)rates were analyzed to compare prognostic outcomes between the cholecystectomy(«=114)and non-cholecystectomy groups(n=228).Univariate and multivariate Cox analyses were performed to assess potential risk factors for OS and DFS.Major complications were also compared between the groups.Results:After matching,no significant differences between groups were observed in baseline characteristics.The 1-,3-,and 5-year OS rates were 96.5%,82.1%,and 67.1%in the cholecystectomy group,and 97.4%,85.2%,and 74.4%in the non-cholecystectomy group(P=0.396);the 1-,3-,and 5-year DFS rates were 58.4%,34.5%,and 26.6%in the cholecystectomy group,and 73.6%,44.7%,and 32.2%in the non-cholecystectomy group(P=0.026),respectively.The intrahepatic distant recurrence rate in the cholecystectomy group was significantly higher than that in the non-cholecystectomy group(P=0.026),and the local tumor recurrence and extrahepatic recurrence rates did not significantly differ between the groups(P=0.609 and P=0.879).Multivariate analysis revealed that cholecystectomy(HR=1.364,95%Cl 1.023-1.819,P=0.035),number of tumors(2 vs.1:HR=2.744,95%Cl 1.925-3.912,P<0.001;3 vs.1:HR=3.411,95%Cl 2.021-5.759,P<0.001),and y-GT levels(HR=1.003,95%Cl 1.000-1.006,P<0.024)were independent risk factors for DFS.The best y-GT level cut-off value for predicting median DFS was 39.6 U/L(area under the curve=0.600,P<0.05).A positive correlation was observed between cholecystectomy and y-GT level(r=0.108,95%Cl-0.001-0.214,P=0.047).Subgroup analysis showed that the DFS rates were significantly higher in the non-cholecystectomy group than the cholecystectomy group when Y-GT>39.6 U/L(i3=0.044).The 5-,10-,15-,20-,and 25-year recurrence rates from the time of cholecystectomy were 2.63%,21.93%,42.11%,58.77%,and 65.79%,respectively.A significant positive correlation was observed between cholecystectomy and the time from cholecystectomy to recurrence(r=0.205,95%Cl 0.016-0.379,P=0.029).There were no significant differences in complications between groups(P=0.685).Conclusions:Patients with HCC who underwent cholecystectomy were more likely to develop intrahepatic distant recurrence after MWA,an outcome probably associated with increased y-GT levels.Moreover,the recurrence rates increased with time.Hongcai Yang Yi Yang Jianping Dou Rui Cui Zhigang Cheng Zhiyu Han Fangyi Liu Xiaoling Yu Xiang Zhou Jie Yu Ping Liang 2020Cancer Biology & Medicine2020,17,2:3
15Bioinformatics analysis of microarray data to explore the key genes involved in HSF4 mutation-induced cataract显示文摘AIM: To reveal the mechanisms of heat-shock transcription factor 4(HSF4) mutation-induced cataract. METHODS: GSE22362, including 3 HSF4-null lens and 3 wild-type lens, was obtained from Gene Expression Omnibus database. After data preprocessing, the differentially expressed genes(DEGs) were identified using the limma package. Based on Database for Annotation, Visualization and Integrated Discovery(DAVID) tool, functional and pathway enrichment analyses were performed for the DEGs. Followed by protein-protein interaction(PPI) network was constructed using STRING database and Cytoscape software. Furthermore, the validated microRNA(miRNA)-DEG pairs were obtained from miRWalk2.0 database, and then miRNA-DEG regulatory network was visualized by Cytoscape software. RESULTS: A total of 176 DEGs were identified in HSF4-null lens compared with wild-type lens. In the PPI network,FBJ osteosarcoma oncogene(FOS), early growth response1(EGR1) and heme oxygenase(decycling) 1(HMOX1) had higher degrees and could interact with each other. Besides,mmu-miR-15 a-5 p and mmu-miR-26 a-5 p were among the top 10 miRNAs in the miRNA-DEG regulatory network.Additionally, mmu-miR-26 a-5 p could target EGR1 in the regulatory network. CONCLUSION: FOS, EGR1, HMOX1, mmu-miR-26 a-5 p and mmu-miR-15 a-5 p might function in the pathogenesis of HSF4 mutation-induced cataract.Rui Tian Yang Xu Wen-Wen Dou Hui Zhang 2018International Journal of Ophthalmology(English edition)2018,11,6:3
16Research on ultra-small textured surface of multicrystalline silicon solar cell显示文摘The ultra-small textured surface of multicrystalline silicon solar cell,prepared by electroless chemical-etching method,shows an excellent anti-reflection property over a wide spectral bandwidth.A novel back surface protection method and front surface passivation method have been used in the multicrystalline solar cells with ultra-small textured surfaces.With these improvements,the back surface remains intact after the etch process and the efficient minority lifetime is apparently increased.The test result shows that the solar cell with ultra-small textured surface can obtain better electrical performances by these improvements.LI HaoFeng JIA Rui DOU BingFei CHEN Chen XING Zhao YANG YongZhou DING WuChang MENG YanLong LIU XinYu YE TianChun LI ShangQing 2013Science China(Technological Sciences)2013,56,4:2
17Combination therapy using microwave ablation and d-mannose-chelated iron oxide nanoparticles inhibits hepatocellular carcinoma progression显示文摘Despite being a common therapy for hepatocellular carcinoma(HCC),insufficient thermal ablation can leave behind tumor residues that can cause recurrence.This is believed to augment M2 inflammatory macrophages that usually play a pro-tumorigenic role.To address this problem,we designed D-mannose-chelated iron oxide nanoparticles(man-IONPs) to polarize M2-like macrophages into the antitumor Ml phenotype.In vitro and in vivo experiments demonstrated that man-IONPs specifically targeted M2-like macrophages and accumulated in peri-ablation zones after macrophage infiltration was augmented under insufficient microwave ablation(MWA).The nanoparticles simultaneously induced polarization of pro-tumorigenic M2 macrophages into antitumor M1 phenotypes,enabling the transformation of the immunosuppressive microenvironment into an immunoactivating one.Post-MWA macrophage polarization exerted robust inhibitory effects on HCC progression in a well-established orthotopic liver cancer mouse model.Thus,combining thermal ablation with man-IONPs can salvage residual tumors after insufficient MWA.These results have strong potential for clinical translation.Rui Cui Luo Wang Dongyun Zhang Kun Zhang Jianping Dou Linan Dong Yixuan Zhang Jiapeng Wu Longfei Tan Jie Yu Ping Liang 2022Acta Pharmaceutica Sinica B2022,12,9:2
18One-Pot Synthesis of Hierarchically Nanoporous SSZ-13 for Conversion of Methanol to Olefins显示文摘The main disadvantage of microporous SSZ-13 catalyst used in the methanol to olefins(MTO) process is its rapid deactivation due to its relatively low coke resistance. Meanwhile, the hierarchical zeolites usually exhibit improved catalytic stability thanks to their better mass transfer ability. Herein, the hierarchically nanoporous SSZ-13 zeolites were one-pot synthesized by using N,N,N-trimethyl-1-adamantanammonium hydroxide as a microporous structure directing agent and C_(18)H_(37) N^+(CH_3)_2 C_6H_(12) N^+(CH_3)_2 C_6 H_(13)(Br^-)_2(hereinafter abbreviated as C_(18-6-6) Br_2) as a mesoporogen. The hierarchically nanoporous SSZ-13 catalyst was characterized by XRD, N_2 physisorption, SEM, TEM, TG-DTG, ^(27) Al and ^(29) SiNMR spectroscopy and NH_3-TPD techniques. The results showed that the hierarchical SSZ-13 zeolite synthesized in the presence of the C_(18-6-6) Br_2 surfactant exhibits aggregates of primary nanocrystals and contains the well-developed mesopores and excellent acidity. Compared to its conventional counterpart, the hierarchical SSZ-13 zeolite has longer catalytic lifetime and higher selectivity for ethylene and propylene in the MTO reaction, which can be attributed to the synergistic effect of their good acidity and improved diffusion properties resulted from the hierarchical pore structure.Li Yuping Wang Yanyue Zhang Yi Liu Rui Li Xiaofeng Dou Tao 2017China Petroleum Processing & Petrochemical Technology2017,19,3:2
19A high-contrast coronagraph for direct imaging of Earth-like exoplanets: design and test显示文摘A high-contrast coronagraph for direct imaging of an Earth-like exoplanet at the visible band needs a contrast of 10-10 at a small angular separation of 4λ/D or less. Here we report our recent laboratory experiment that approaches these limits. Our test of a high-contrast imaging coronagraph is based on our step-transmission apodized filter. To achieve this goal, we use a liquid crystal array as a phase corrector to create a dark hole based on our dedicated algorithm. We have suppressed the diffraction and speckle noise near the point image of a star to a level of 1.68 × 10-9at4λ/D, which can be used for direct imaging of Jupiter-like exoplanets. This demonstrates that a telescope incorporating a high-contrast coronagraph in space has the potential to detect and characterize Earth-like planets.Cheng-Chao Liu De-Qing Ren Jiang-Pei Dou Yong-Tian Zhu Xi Zhang Gang Zhao Zhen Wu Rui Chen 2015Research in Astronomy and Astrophysics2015,15,3:2
20Mitochondrial temperature-responsive drug delivery reverses drug resistance in lung cancer显示文摘Reversal of cancer drug resistance remains a critical challenge in chemotherapy.Mitochondria-targeted drug delivery has been suggested to mitigate drug resistance in cancer.To overcome the intrinsic limitations in conventional mitochondrial targeting strategies,we develop mitochondrial temperature-responsive drug delivery to reverse doxorubicin(DOX)resistance in lung cancer.Results demonstrate that the thermoresponsive nanocarrier can prevent DOX efflux and facilitate DOX accumulation and mitochondrial targeting in DOX-resistant tumors.As a consequence,thermoresponsive nanocarrier enhances the cytotoxicity of DOX and reverses the drug resistance in tumor-bearing mice.This work represents the first example of mitochondrial temperature-responsive drug delivery for reversing cancer drug resistance.Lifo Ruan Jun Chen Chuanchao Du Huiru Lu Jiayu Zhang Xiaomeng Cai Rui Dou Wenchu Lin Zhifang Chai Guangjun Nie Yi Hu 2022Bioactive Materials2022,7,7:1
