The abuse and nonstandard use of medical technology lead to various social issues,while the current medical technology assessment is still quite backward.Under these circumstances,it is of urgent need to emphasize the significance of medical technology assessment,strengthen assessment of the social adaptability of medical technology,proceed the whole-range assessment,build an independent review board,and improve the quality of assessment workers.In order to realize the above goals,we should transform government's role-orientation,strengthen the managing function of government,and perfect hospital management system.

Abuse of medical technology is ever more prominent in current medical practice.The rapid development of medical technology brings us a great opportunity to improve the role of moral construction,propel transformation of moral concept,and achieve the harmony between the implemental rationality and value rationality.In order to regulate to the application of medical technology,construction of responsibility ethics as well as ideal education should be strengthened.Both the construction of individual ethics and systemized ethics must be emphasized.The former dynamic mode of management must be changed and construction of medical ethics committee be emphasized so as to systemize and organize the ethical assessment of medical technology.

The network teaching reformation is a result of the rapid development of internet technology and the creation of constructivism theory.The Webquest form practice of network teaching depends on the careful analysis of network teaching aim,the reasonable design of network teaching content,and the scientific arrangement of network teaching plate.The application of the Webquest form is a useful attempt.It is helpful to improve the comprehensive qualities of medical students.And it is helpful to re-construct the relationship between the teacher and the student.

When the reproduction subject maintains his or her own reproduction rights,meanwhile he or she must respect other's corresponding rights,thus to reach the balance of right among different reproduction subjects.This paper calls for strengthening the promotion and education of reproduction responsibility ethics,and constructing the ethical surroundings of "sharing rights and responsibility".

Systemized ethics is the evitable choice of the history development. The rise of systemized ethics is the important change of emphasis on morality construction. The implement of systemized ethics is not only beneficial to organically integrate universality and advance, but also realize the moral-living theory. The exertion of function of systemized ethics depends on the degree of systemized ethics.

The innovation of social structure propels the advent of systemized ethics,which is a unity of objectivity and rationality.The systemized ethics is the foundation of the morality reconstruction,and the main manifestation of modern ethics.It's not only universal applicable,but acceptable also.

Guided by the theory of constructivism,we utilize the internet resource to design the teaching of medical ethics under the condition of information,change the traditional teaching method and utilize the new teaching ideas.When teaching knowledge,we also advocate students'ability,attitude and quality.

This paper introduces consistents of an intelligent EEG monitor, including its hardware and software. Emphasis is put on the discussion about the detection of epilepsy waves with wavelet transform. At last, analysis of clinical EEG data show that this system has achievedhighsensitivity and selectivity.

Restenosis is a major complication after percutaneous transluminal coronary intervention. Evaluation of restenosis early and accurately can help to giude treatment, improve outcome and save costs for the patients. All kinds of imaging methods for restenosis have their merits and demerits. It is essential to choose the appropriate imaging method in clinical practice.

Objective To investigate the expression of RCAS1,which is a receptor-binding cancer antigen expressed on SiSo cells in many tumor cell lines. Methods Using real-time polymerase chain reaction(PCR),Northern blot,immunohistochemical examination and enzyme-linked immunosorbent assay,we detected the expre-(ssion) of RCAS1 in 10 different tumor cell lines and two normal cell lines. Results The expression of RCAS1 in the tumor cell lines and the fetal renal cell line(293 cell) was detected by real-time PCR and Northern blot,but not in the normal liver cell line(LO2 cell).The results of immunohistochemical examination on the tumor cell lines and the 293 cell showed that RCAS1 existed in cytoplasma and on cell surface.Except HuH-7 cell and LO2 cell,the soluble RCAS1 protein in supernatants of the other cells was significantly more than that in DMEM(P
