2Bioprinted constructs that simulate nerve-bone crosstalk to improve microenvironment for bone repair显示文摘Crosstalk between nerves and bone is essential for bone repair,for which Schwann cells(SCs)are crucial in the regulation of the microenvironment.Considering that exosomes are critical paracrine mediators for intercellular communication that exert important effects in tissue repair,the aim of this study is to confirm the function and molecular mechanisms of Schwann cell-derived exosomes(SC-exos)on bone regeneration and to propose engineered constructs that simulate SC-mediated nerve-bone crosstalk.SCs promoted the proliferation and differentiation of bone marrow mesenchymal stem cells(BMSCs)through exosomes.Subsequent molecular mechanism studies demonstrated that SC-exos promoted BMSC osteogenesis by regulating the TGF-βsignaling pathway via let-7c-5p.Interestingly,SC-exos promoted the migration and tube formation performance of endothelial progenitor cells.Furthermore,the SC-exos@G/S constructs were developed by bioprinting technology that simulated SC-mediated nerve-bone crosstalk and improved the bone regeneration microenvironment by releasing SC-exos,exerting the regulatory effect of SCs in the microenvironment to promote innervation,vascularization,and osteogenesis and thus effectively improving bone repair in a cranial defect model.This study demonstrates the important role and underlying mechanism of SCs in regulating bone regeneration through SC-exos and provides a new engineered strategy for bone repair.Tianchang Wang Wentao Li Yuxin Zhang Xiang Xu Lei Qiang Weiqiang Miao Xiaokun Yue Xin Jiao Xianhao Zhou Zhenjiang Ma Shuai Li Muliang Ding Junfeng Zhu Chi Yang Hui Wang Tao Li Xin Sun Jinwu Wang 2023Bioactive Materials2023,,9:1
3Analysis of Electric Guitar Improvisation Techniques显示文摘As an important form of modern fusion music performance,electric guitar improvisation is widely praised and welcomed for its unique performance style.The main points and difficulties of its performance lie in tone switching,speed playing skills,and grasping the title,mood,and style of the music.Therefore,it is necessary to integrate the conventional techniques of string sweeping,pizzicato,and dotted strings with improvisation,applying differentiated rhythmic rhythms,timbre modulation,and special playing techniques to deepen the distinctive art-rock music characteristics.Tianchang Li 2023Journal of Contemporary Educational Research2023,7,9:0
4Different therapeutic proportion of patients undergone coronary angiography in the era of development in MSCT显示文摘Objective To study the different therapeutic proportion of the patient populations undergone coronary angiography (CAG) in the era of development in multislice spiral computed tomography(MSCT). Methods Two hundred and fifty four consecutive patients(mean age 59.24±10.65) , who underwent CAG at Daxing Hospital from February 2007 through October 2007, were enrolled, 160 patients were male and 94 were female. By evaluating from the coronary angiogram, the patients were not diagnosed to have coronary heart disease(CHD) with less than 50% diameter stenosis of coronary artery; the patients to have CHD with more than or equal to 50% stenosis of coronary artery; the patients were performed the procedure of percutaneous coronary intervention(PCI) with more than or equal to 70% stenosis; the patients were proposed to have coronary aortic bypass graft(CABG) surgery with left main coronary artery lesions or diffuse triple coronary artery lesions. Results In the 254 consecutive patients, 59 patients(23.2%) had not been diagnosed to have CHD; 195(76.8%)to have CHD, of these patients with CHD, 49 patients(19.3%)were not indicated for PCI (including the patients receiving follow-up coronary angiography after stenting), 81(31.9%)had been performed the procedure of stent implantation, 57(22.4%)proposed to have CABG, 8(3.1%)the procedure of PCI had not been successful, or had not been performed because of patients opposing to this therapy. Conclusion Multislice spiral computed tomography can be applied as a non-invasive screening tool to exclude the presence of CHD, to increase the positive proportion of the populations with CHD in all patients receiving coronary angiograhpy, to avoid the use of CAG in a subset ofJuan Deng Wenbin Wang Shuoqing Hu Yue Xiao Feng Liang Xuewei Guo Haiying Wang Pengchuan Zhang Dayi Hu Tianchang Li Chuzhong Tang Jiyun Wang Changlin Lu 2008Journal of Geriatric Cardiology2008,5,2:0

7Transmission and Development of Musical Art显示文摘American music has developed over a relatively long period of time,but it was only in the early part of the last century that it developed a unique style that has an important place in the musical development of the world.The American environment has seen the formation of different ethnic and national music,as well as different musical styles,which have influenced and blended with each other to promote the development of American music.American modern music has gone through several stages of development,and it has not only formed a certain influence on the local American culture but also influenced the development of music throughout the world.This paper analyzes the heritage and development history of musical art and explains its influential role.Tianchang Li 2023Journal of Contemporary Educational Research2023,7,6:0
8Plasma Concentration of the Novel Peptide Apelin is Regularly Changed in Patients With Heart Failure显示文摘Objectives Apelin, the novel endogenous ligand for the G-protein-coupled receptor APJ, has been observed in many animals and humans studies. It is concluded that it has inotropic effects, hypotension and diuretic properties. The change of apelin in relation to heart failure is still controversial. Our goal was to observe the change of apelin-12 in patients with heart failure (HF). Methods From 2005 to 2006, 81 consecutive patients (46 male and 35 female, mean age 68.5±12.1 years) with heart failure resulting from variable etiologies and 15 healthy controls were included in this study. Plasma concentration of apelin-12 was measured through ELISA on admission. All patients received conven-tional therapy and recorded detailed the clinical condi-tions. Results (1) Plasma concentration of apelin of the controls is lower than the ones of heart failure patients. (2) Plasma concentration of apelin is increased in the early stage and decreased in the advanced period. (3) Apelin is related with variable indexes in the Pearson’s association analysis. Apelin is also changed with the atrium and ventricular’s diameter. Conclusions Plasma concentration of apelin is increased in early stage and decreased in advanced period. The apelin-APJ system might be important in the pathophysiological process of heart failure. And it might be valuable in diagnosis and therapeutic implications in heart failure.Yuan Yanju Li Tianchang Yah Jun Bian Hong Yao Daokuo Xu Shiying Zheng Jianyong 2006South China Journal of Cardiology2006,7,2:0
