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.

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.

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".

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.

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.

Objective:To observe the roles of p50 protein in pathologic responses of cerulein(CR)pancreatitis in mice deficient in p50 protein of NF-?B.Methods:Pancreatitis was induced by i.p.injection of 50?g/kg CR.The express and compensation of p65,p50 and cRel proteins of NF-?B,NF-?B activity were measured using electromobility shift assay;parameters of pancreatitis,eg,amylase,lipase and trypsin were evaluated.The apoptosis,necrosis and caspase-3 activity were observed.Results:p50 knockout(KO)mice had no p50 protein expression and increased p65 and cRel proteins expression.p50 KO mice's NF-?B activity decreased and apoptosis increased in pancreatitis compared with wild type(WT)mice.There was no caspase-3 activition in both mice before and after pancreatitis.All KO mice had an increased necrosis and amylase,lipase,trypsin activity compared with WT mice in pancreatitis.Conclusions:The results indicated that NF-?B p50 genetic deletion might attenuate cerulean induced pancreatitis.

To evaluate the influence of combined endurance and strength training on the knee flexors and extensors strength of Chinese army male recruits. At the beginning and end of their 4 weeks′ combined endurance and strength training, twenty recruits received isokinetic dynamometer test for flexors and extensors of both knees with the Cybex 6000 isokinetic dynamometer. after training, there was a significant increase in the peak torque values, torque acceleration energy, and endurance ratio of flexors of both knees at two angular velocities (60?/s,180?/s). Meanwhile, the torque acceleration energy and endurance ratio were increased in the extensors of both knees at two angular velocities . It suggested that four weeks of combined endurance and strength training for the recruits is effective in terms of increasing muscular strength, explosive force and muscular endurance of knee flexors and extensors. More loads should be applied to strengthen the strength of the extensors.

To evaluate the influence of combined endurance and speed training on the knee flexors and extensors strength of army male recruits. At the beginning and end of their 4 week combined endurance and speed training, twenty recruits received isokinetic dynamometer test of flexors and extensors of both knees with the Cybex 6000 isokinetic dynamometer. The results showed: that there was a significant increase in the peak torque values, torque acceleration energy and endurance ratio of left knee flexors at high angular velocities (180?/s) after training. Meanwhile, the peak torque and endurance ratio were increased in left knee extensors at high angular velocities (180?/s),and the peak torque and torque acceleration energy were increased in right flexors at high angular velocities(180?/s). These data suggest that four weeks of combined endurance and speed training for recruits is not sufficient fo increase muscular strength, explosive force or muscular endurance of knee flexors and extensors.
