| 1 | Benzene alkylation with methanol over phosphate modified hierarchical porous ZSM-5 with tailored acidity显示文摘The acidity and acid distribution of hierarchical porous ZSM-5 were tailored via phosphate modification. The catalytic results showed that both benzene conversion and selectivity of toluene and xylene increased with the presence of appropriate amount of phosphorus. Meanwhile, side reactions such as methanol to olefins related with the formation of by-product ethylbenzene formation and isomerization of xylene to meta-xylene were suppressed efficiently. The acid strength and sites amount of Br?nsted acid of the catalyst were crucial for improving benzene conversion and yield of xylene, whereas passivation of external surface acid sites played an important role in breaking thermodynamic equilibrium distribution of xylene isomers. | Jinghui Lyu Hualei Hu Carolyn Tait Jiayao Rui Caiyi Lou Qingtao Wang Wenwen Han Qunfeng Zhang Zhiyan Pan Xiaonian Li | 2017 | Chinese Journal of Chemical Engineering2017,25,9: | 11 |

| 3 | Evaluation of coronary plaque and stent deployment by intravascular optical coherence tomography in elderly patients with unstable angina and non-ST-elevation myocardial infarction显示文摘Objective To evaluate the feasibility and efficacy of intravascular optical coherence tomography (OCT) in the assessment of plaque characteristics and drug eluting stent deployment quality in the elderly patients with unstable angina (UA) and non-ST segment elevation myocardial infarction (NSTEMI). Methods OCT was used in elderly patients undergoing percutaneous coronary interventions. Fifteen patients, 9 males and 6 females with mean age of 72.6±5.3 years (range 67-92 years) were enrolled in the study. Images were obtained before initial balloon dilatation and following stent deployment. The plaque characteristics before dilation, vessel dissection, tissue prolapse, stent apposition and strut distribution after stent implantation were evaluated. Results Fifteen lesions were selected from 32 angiographic lesions as study lesions for OCT imaging after diagnostic coronary angiography. There were 7 lesions in the left anterior descending artery, 5 lesions in the right coronary artery and 3 lesions in the left circumflex coronary artery. Among them, 12 (80.0%) were lipid-rich plaques, and 10 (66.7%) were vulnerable plaques with fibrous cap thickness 54.2±7.3 μm. Seven ruptured culprit plaques (46.7%) were found; 4 in UA patients and 3 in NSTEMI patients. Tissue prolapse was observed in 11 lesions (73.3%). Irregular stent strut distribution was detected in 8 lesions (53.3%). Vessel dissections were found in 5 lesions (33.3%). Incomplete stent apposition was observed in 3 stents (20%) with mean spacing between the struts and the vessel wall 172±96 mm (range 117-436 mm). Conclusions 1) It is safe and feasible to perform intravascular OCT to differentiate vulnerable coronary plaque and monitor stent deployment in elderly patients with UA and USTEMI. 2) Coronary plaques in elderly patients with UA and USTEMI could be divided into acute ruptured plaque, vulnerable plaque, lipid-rich plaque, and stable plaque. 3) Minor or critical plaque rupture is one of the mechanisms of UA in elderly patients. 4) Present drug eluting stent implantation is complicated with multiple tissue prolapses which are associated with irregular strut distributions. 5) The action and significance of tissue prolapse on acute vessel flow and in-stent thrombus and restenosis need to be further studied. | Caiyi LU Shiwen WANG Wei YAN Xingli WU Yuxiao ZHANG Qiao XUE Muyang YAN Peng LIU Rui CHEN Jinyue ZHAI | 2007 | Journal of Geriatric Cardiology2007,4,1: | 3 |
| 4 | Primary User Adversarial Attacks on Deep Learning-Based Spectrum Sensing and the Defense Method显示文摘The spectrum sensing model based on deep learning has achieved satisfying detection per-formence,but its robustness has not been verified.In this paper,we propose primary user adversarial attack(PUAA)to verify the robustness of the deep learning based spectrum sensing model.PUAA adds a care-fully manufactured perturbation to the benign primary user signal,which greatly reduces the probability of detection of the spectrum sensing model.We design three PUAA methods in black box scenario.In or-der to defend against PUAA,we propose a defense method based on autoencoder named DeepFilter.We apply the long short-term memory network and the convolutional neural network together to DeepFilter,so that it can extract the temporal and local features of the input signal at the same time to achieve effective defense.Extensive experiments are conducted to eval-uate the attack effect of the designed PUAA method and the defense effect of DeepFilter.Results show that the three PUAA methods designed can greatly reduce the probability of detection of the deep learning-based spectrum sensing model.In addition,the experimen-tal results of the defense effect of DeepFilter show that DeepFilter can effectively defend against PUAA with-out affecting the detection performance of the model. | Shilian Zheng Linhui Ye Xuanye Wang Jinyin Chen Huaji Zhou Caiyi Lou Zhijin Zhao Xiaoniu Yang | 2021 | China Communications2021,18,12: | 3 |
| 5 | Using optogenetics to translate the “inflammatory dialogue” between heart and brain in the context of stress显示文摘Inflammatory processes are an integral part of the stress response and are likely to result from a programmed adaptation that is vital to the organism's survival and well-being.The whole inflammatory response is mediated by largely overlapping circuits in the limbic forebrain,hypothalamus and brainstem,but is also under the control of the neuroendocrine and autonomic nervous systems.Genetically predisposed individuals who fail to tune the respective contributions of the two systems in accordance with stressor modality and intensity after adverse experiences can be at risk for stress-related psychiatric disorders and cardiovascular diseases.Altered glucocorticoid(GC) homeostasis due to GC resistance leads to the failure of neural and negative feedback regulation of the hypothalamic-pituitary-adrenal axis during chronic inflammation,and this might be the mechanism underlying the ensuing brain and heart diseases and the high prevalence of co-morbidity between the two systems.By the combined use of light and genetically-encoded lightsensitive proteins,optogenetics allows cell-type-specific,fast(millisecond-scale) control of precisely defined events in biological systems.This method is an important breakthrough to explore the causality between neural activity patterns and behavioral profiles relevant to anxiety,depression,autism and schizophrenia.Optogenetics also helps to understand the 'inflammatory dialogue',the inflammatory processes in psychiatric disorders and cardiovascular diseases,shared by heart and brain in the context of stress. | Jinbo Cheng Jie Zhang Caiyi Lu Liping Wang | 2012 | Neuroscience Bulletin2012,28,4: | 3 |

| 7 | Six-month results of a biodegradable polymer and rapamycin-coating stent for coronary artery disease显示文摘Objective To assess the safety and efficacy of a novel biodegradable polymer and rapamycin-coating stent, the EXCEL stent, in the treatment of coronary artery disease (CAD), as compared with the CypherTM stent. Methods In this prospective, non-randomized study, 60 consecutive patients with symptomatic CAD received either an EXCEL stent (n=32), or a CypherTM stent(n=28),according to their respective treatment intention. Follow-up angiography was performed at a mean of 180±40 days. The primary endpoint of the study was the occurrence of a major adverse cardiac event (MACE), including death, myocardial infarction, or target-vessel revascularization during the 6 months after stenting. The secondary end points included the in-stent late luminal loss (LLL), percentage of in-stent stenosis of the luminal diameter, and the rate of restenosis (luminal narrowing of 50 percent or more) at 6 months. Results There were no significant differences between the two groups in baseline characteristics, including the distribution of target vessel and lesion types. During the follow up period of 6 months, there were no occurrences of MACE in either group. Twenty-seven patients(84%) in the EXCEL group and 10 (36 %) in the CypherTM group underwent quantitative coronary angiography at 6 months. For these patients, no restenosis occurred, and there were no differences in the in-stent stenosis of the luminal diameter (5.98±5.52% vs 5.21 ±6.3%,P>0.05) and the LLL (-0.02±0.09 mm vs -0.01±0.07 mm, P>0.05). Conclusions Compared with the CypherTM stent, the EXCEL Stent with biodegradable polymer and rapamycin-coating showed similar efficacy in the prevention of neointimal proliferation, restenosis, and associated clinical events in CAD patients. | Yuxiao ZHANG Caiyi LU Qiao XUE Peng LIU Wei YAN Rui CHEN | 2006 | Journal of Geriatric Cardiology2006,3,2: | 1 |
| 8 | C-reactive protein as a predictor for cardiac events in Chinese elderly patients with coronary heart disease显示文摘Background and objective To assess the predictive value of C-reactive protein(CRP) for major adverse cardiac events and the association between CRP level and the coronary lesion morphology and extent in patients with coronary heart disease (CHD).Methods CRP was measured on admission in 177 consecutive elderly (age≥60 years) patients with CHD who underwent coronary angiography. Patients were divided into high CRP group (CRP≥3mg/L) and normal CRP group (CRP <3mg/L). The association between CRP levels and the coronary lesion features, including severity of stenosis (mild, moderate, severe), extent of lesion (diffused or nondiffused), eccentricity of the plaque (eccentric or non-eccentric) were analyzed. Patients were followed up for a mean of 8 months for the occurrences of major adverse cardiac events (MACE). Results Compared with patients in normal CRP group, patients in high CRP group were more frequently to have unstable angina, multi-vessel, diffuse, eccentric lesions, positive remodeling, and non-smooth plaques (P<0.01). Kaplan-Meier analysis showed patients in high CRP group had a significantly lower MACE-free survival rate than patients in normal CRP group (Log-rank = 12.0, P<0.01); Cox regression analysis indicated CRP level as an independent predictor for the occurrence of MACE (OR=3.16, P<0.05) Conclusions High CRP level is associated with more extend, severe and eccentric coronary lesions and is an independent predictor for MACE in elderly patients with CHD. | Guangyong HUANG Caiyi LU Xingli WU Yuxiao ZHANG | 2006 | Journal of Geriatric Cardiology2006,3,2: | 1 |

Methods : Patients were selected to the study if: 1) age >65 years; 2) with coexistence of two or more cardiovascular diseases which are indications for interventional therapy; 3) patients' general condition and organ functions allow the performance of combined multiple procedures; 4) the predicted procedure time is within 150 min; 5) the predicted contrast medium dosage is within 300 ml. The criteria we analyzed included procedural type, rocedural time, fluoroscopy time, dosage of contrast medium, success rates of the procedures, complications and in-hospital mortality. All patients were followed up for 30.4 ± 9.3 months,to determine the all-cause mortality, recurrence rates and adverse cardiac events. Results : From January 2000 to December 2004,combined interventional procedures were performed on 136 patients, with 2 procedures on 134 patients and 3 procedures on 2 patients.The mean procedure time was 115.4±11.6 min, the mean fluoroscopy time was 35.7±9.3 min, and the mean dosage of contrast medium used was 183.6±19.4 ml. Procedural success rate was 100%, no procedure related death or major complications occurred.Conclusion: Performed by a competent team, combined interventional procedures in elderly patients with multiple cardiovascular diseases were feasible and relatively safe. | Caiyi LU Shiwen WANG Xinli WU Qiao XUE Taohong HU Muyang YAN Rui CHEN Zhongren ZHAO Haiyun WU | 2005 | Journal of Geriatric Cardiology2005,2,3: | 1 |
| 10 | Long-term effect of stenting in unprotected left main coronary artery disease in the elderly显示文摘To evaluate the feasibility, safety and efficacy of percutaneous stent implantation for treating left main coronary artery (LMCA) stenosis. Methods Consecutive patients with unprotected left main coronary artery disease treated by stent-based percutaneous intervention (PCI) at 6 medical centers in China were enrolled. Procedural data and clinical outcomes were obtained from all patients. Results From January 2001 to December 2004, 138 patients (79 males and 59 females; mean age: 69.7±5.8 years)underwent PCI for LMCA stenosis. Bare metal stents (BMS) were implanted in 51 patients with non-bifurcational lesions and in 5 patients with bifurcational lesions from January of 2001 to June of 2003 (BMS group);. Drug eluting stents (DES) were used unselectively to cover both bifurcational and non-bifurcational lesions in 86 patients from July of 2003 to December of 2004 (DES group). Procedural success rate of the 138 cases was 98% (135/138). One patient (0.7%) with bifurcation lesion who was treated with DES died from severe heart failure 2 weeks after the procedure. During a mean follow up period of 21.3 ± 5.6 months, one patient died from renal failure, one from sudden cardiac death, 4 underwent target lesion revascularization (TLR) in the BMS group, which all occurred in patients with bifurcational lesions; whereas in the DES group no deaths occurred and only one patient with bifurcational lesion had TLR. Conclusions (1) PCI is feasible and relatively safe to treat unprotected left main coronary artery disease in elderly patients at medical centers with experienced professionals. (2) BMS and DES have similar immediate and long-term efficacy in the treatment of ostium and shaft lesions of the LMCA. (3) DES are strongly suggested in the therapy of distal bifurcation lesion of unprotected LMCA. | Caiyi LU Shiwen WANG Lingling LIU Qiao XUE Xinli WU Taohong HU Pingshuan DONG Zhiping WANG Shenfang TIAN Pinfa LIU Jicai ZANG | 2005 | Journal of Geriatric Cardiology2005,2,4: | 1 |

| 16 | Insight into the Dual Cycle Mechanism of Methanol-to-OIefins Reaction over SAPO-34 Molecular Sieve by Isotopic Tracer Studies显示文摘Methanol-to-olefins(MTO)reaction is one of the important non-petroleum routes to produce light olefinsover acidic molecular sieves.In this study,the complete reaction course of MTO on SAPO-34 molecular sieve with retained organics evolution from induction period to deactivation period was investigated systematically at different weight hourly space velocities(WHSV)of methanol.By the aid of 12C/3C-methanol isotopic switch experiment,the dual cycle mechanism involving aromatics-based cycle and alkenes-based cycle was evaluated during the whole reac-tion process.The detailed reaction route varied with the evolution of the retained organics in the catalyst at different reaction stages.The aromatics-based cycle and alkenes-based cycle alternately dominate the reaction process.In the efficient reaction period,aromatics-based cvcle is the main reaction mechanism,while in the induction and deactiva-tion periods.the contribution of alkenes-based cvcle mechanism will become more important. | YU Bowen LOU Caiyi ZHANG Wenna XU Shutao HAN Jingfeng YU Zhengxi WEI Yingxu LIU Zhongmin | 2020 | Chemical Research in Chinese Universities2020,36,6: | 1 |
