Lipids changes in liver cancer

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus （HBV） and hepatitis C virus （HCV）. HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.     

Novel distribution pattern of fibrinolytic components in rabbit tissues extract： a preliminary study

Objective: The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues. Methods: The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and α2 plasmin inhibitor (α2PI), were determined by colorimetric assay. Results: The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and α2PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and α2PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the α2PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and α2PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and α2PI were significantly lower than those in skeletal muscle. Conclusion: Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues.     

语言实验室在大学英语形成性评价中的作用

高职与本科新生攻击倾向的比较研究

采用AQ攻击性问卷,对本科与高职的655名新生进行问卷调查。结果显示,12.83%的学生AQ总分在中等以上;高职生高分检出率高于医学生;在身体攻击、愤怒因子及总分上与医学生差异非常显著。研究表明,被试总体攻击倾向低于成人平均水平,学业成绩可能是导致两所学校新生攻击倾向差异的重要中介变量。     

高校一专多能型辅导员队伍建设的制度保障

一专多能型辅导员自20世纪80年代以来成为高校政治辅导员发展的一大趋势。教育主管部门、各高校也日益注意到一专多能型辅导员队伍建设的重要性,在重视政治辅导员的一专多能对班级工作的促进作用的同时,更加关心政治辅导员一专多能素质的全面提高。为此,需要我们建立并完善政治辅导员专业学位制度、政治辅导员＂双证书＂制度、政治辅导员资格证书制度、政治辅导员培训制度、政治辅导员职务岗位聘任制度和政治辅导员公开选拔制度,以此来保障一专多能型辅导员队伍的建设与发展。
