| 1 | A disintegrin and metalloproteinase with thrombospondin motif 1(ADAMTS1) expression increases in acute aortic dissection显示文摘Acute aortic dissection(AAD) is a life-threatening cardiovascular disease caused by progressive medial degeneration of the aortic wall. A disintegrin and metalloproteinase with thrombospondin motifs 1(ADAMTS1) is a recently identified extracellular metalloproteinase participating in the development of vascular disease, such as atherosclerosis. In the present study, we found that ADAMTS1 was significantly elevated in blood samples from AAD patients compared with patients with acute myocardial infarction and healthy volunteers. Based on these findings, we established an AAD model by infusing angiotensin II in older mice. AAD was successfully developed in aorta tissues, with an incidence of 42% after 14 days in the angiotensin II group. Macrophage and neutrophil infiltration was observed in the media of the aorta, and ADAMTS1 overexpression was found in the aorta by Western blot and immunohistochemistry. Double immunofluorescence staining showed the expression of ADAMTS1 in macrophages and neutrophils. Consistent with the upregulation of ADAMTS1 in aortic dissection tissues, versican(a proteoglycan substrate of ADAMTS1) was degraded significantly more in these tissues than in control aortic tissues. These data suggest that the increased expression of ADAMTS1 protein in macrophages and neutrophils that infiltrated aortic tissues may promote the progression of AAD by degrading versican. | Yanxiang Gao Wenjing Wu Changan Yu Fangming Zhong Geng Li Wei Kong Jingang Zheng | 2016 | Science China(Life Sciences)2016，59，1： | 8 |

| 3 | A CONTINUUM DAMAGE MODEL OF AGING CONCRETE显示文摘There is up to now no constitutive model in the current theories of CDM that could give a description for the degradation of aging concrete. The two internal state variables β and ω are introduced in this paper. β is called cohesion variable as an additional kinematic parameter, reflecting the cohesion state among material particles. ω is called damage factor for micro-defects such as voids.Then a damage model and a series of constitutive equations are developed on Continuum Mechanics.The model proposed could give a valid description for the whole-course-degradation of aging concrete due tochemical and mechanical actions. Finally, the validity of the model is evaluated by an example and experimental results. | Zhao Zhenyang Xie Huicai Xu Tao Yu Jie Cai Changan | 2001 | Acta Mechanica Solida Sinica2001，14，1： | 0 |
| 4 | Mechanism and Research Progress of Fuyang Huoxue Jiedu Formula against Recurrence of Ulcerative Colitis显示文摘By introducing the composition and modern pharmacology of Fuyang Huoxue Jiedu Formula,the paper further explored the mechanism and research progress of Fuyang Huoxue Jiedu Formula against recurrence of ulcerative colitis(UC).The formula can effectively improve the TCM syndromes of UC patients,reduce the recurrence rate,and improve clinical efficacy and patients’quality of life. | Yi LI Changan ZHOU Rongrong LI Jiaojiao ZHANG Xingxing YU | 2022 | Medicinal Plant2022，13，6： | 0 |
| 5 | A Formula of Solution for a Class of Linear Recurence with Two Indices显示文摘It is very difficult, sometimes impossible, to get a formula solution of recurrence relation, even for the case of homogeneous recurrence with one indice. In this paper, according to the principle of soluting algebraic equation, we present the formula of solution for a class of recurrnce relations with two indices by appling iteration and induction. It provides a concrete model to solve the concerning problems with modern computing tools. | YU Changan | 2006 | Wuhan University Journal of Natural Sciences2006，11，3： | 0 |
