两种简便测定尿肌酐排出量的方法     

林文Tao  黄丽英 《上海体育学院学报》1996,20(2):39-42

采用实验评定法,对同一天的尿液分别测定两个时段的尿肌酐量、晨尿肌酐量及全日尿肌酐量,并对两种简便测定尿肌酐的方法进行分析比较。结果表明,两段尿测定法与一段尿法均能比较客观代表全日尿肌酐量。  相似文献

了解大学新生心理健康状况，及早发现问题，进行治疗，具有十分重要的意义。我们在1995年10月、11月对95级新生进行了心理健康调查，共收回有效答卷2069份，情况分析如下：一、我校95级新生心理健康现状从调查看，大部分新生的心理比较健康，但相当一部分新生心理状况不容乐观。（一）95级新生心理健康不良者比例颇高，平均为30．5％，比例最高班级为46．0％，比例最低班级也有22．5％；有明显心理问题的学生375人，占受测学生总数18．l％；有严重心理问题者ZI人，占l／，想轻生者11人，占0．5％。但自我感觉有心理问题者和主动提出咨询需…  相似文献   

Novel high torque bearingless two-sided rotary ultrasonic motor   总被引：3，自引：0，他引：3  

LI Xia CHEN Wei-shan XIE Tao LIU Jun-kao 《浙江大学学报(A卷英文版)》2007,8(5):786-792

Applications are limited at present because the currently available ultrasonic motors (USMs) do not provide suffi-ciently high torque and power. The conventional travelling-wave USM needs the bearing to support, which required lubricant. To solve the above problem, a bearingless travelling-wave USM is designed. First, a novel structure of the two-sided USM consisting of a two-sided teeth stator and two disk-type rotors is designed. And the excitation principle of the two-sided travelling-wave USM is analyzed. Then, using ANSYS software, we set up the model of the stator to predict the excitation frequency and modal response of the stator. The shape of the vibration mode was obtained. Last, the load characteristics of the USM are measured using ex-perimental method. The maximum stall torque and the no-load speed were obtained. The results showed that the characteristics of the two-sided USM are better than those of the conventional one-sided USM.  相似文献   

Cell therapy in congestive heart failure   总被引：5，自引：0，他引：5  

Tao ZW  Li LG 《Journal of Zhejiang University. Science. B》2007,8(9):647-660

Congestive heart failure （CHF） has emerged as a major worldwide epidemic and its main causes seem to be the aging of the population and the survival of patients with post-myocardial infarction. Cardiomyocyte dropout （necrosis and apoptosis） plays a critical role in the progress of CHF; thus treatment of CHF by exogenous cell implantation will be a promising medical approach. In the acute phase of cardiac damage cardiac stem cells （CSCs） within the heart divide symmetrically and/or asymmetrically in response to the change of heart homeostasis, and at the same time homing of bone marrow stem cells （BMCs） to injured area is thought to occur, which not only reconstitutes CSC population to normal levels but also repairs the heart by differentiation into cardiac tissue. So far, basic studies by using potential sources such as BMCs and CSCs to treat animat CHF have shown improved ventricular remodelling and heart function. Recently, however, a few of randomized, double-blind, placebo-controlled clinical trials demonstrated mixed results in heart failure with BMC therapy during acute myocardial infarction.  相似文献
