Objective To compare and evaluate the effect of PBL in clinical teaching of Pediatrics.Methods Among students of Grade 2002 in our university,two types of PBL,pre-learning and case-discussion,were used in their clinical learning of Pediatrics. And then,their effects were evaluated and compared with those of traditional learning method.Results More than 60% of the students agreed with PBL methods,and they considered PBL favorable to practice scientific logical thinking of clinical affairs,to increase their capabilities of learning,oral expression,communication and cooperation.The teachers agreed with PBL methods too for the better learning effect resulting from PBL.Conclusion PBL fits the needs of medical learning reformation.To train new type of doctors in century 21st,it is necessary to use kinds of new learning methods,including PBL methods and standardized patient (SP)in clinical teaching.

Characteristics and measurement principles of reference methods in clinical biochemistry were described.Implementation of reference systems is one of the most effective approaches to improve the accuracy and comparability of clinical laboratory test results.Reference methods are the key components of reference systems.Reference methods should have measurement uncertainties that meet the requirements of the intended use,and thus should be based on reliable measurement principles.For the well-defined biochemistry analytes,reference methods have been almost all based on instrumental analysis.Isotope dilution mass spectrometry (ID/MS) is considered most reliable and has been the major analytical principle of the reference methods.ID/MS analysis is accurate but expensive.Use of other validated instrumental analyses as reference measurement principles would be justified.

T were also detected in the controls.Conclusion Nephrotic syndrome may be associated with NPHS2 identified in children.

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.
