Objective To explore the relationship between dental trauma for children and their psychological behavior characteristics.Methods By using the method of case-control study,7-11 years of age children accepting oral health examination in our department were asked to fill in the questionnaire.The children without dental trauma were selected as the control group and the children with permanent tooth injury were selected as the injury group.Each group has 57 cases.All children finished the Eysenck personality questionnaire (EPQ) and their parents finished the Achenbach child behavior capacity list (CBCL).Results (1) The average CBCL score (32.51±20.41) and scores of P and N branch capacity lists in EPQ (44.72± 11.67,48.05± 12.39) of the injury group were all higher than those of the control group (17.19± 11.67,37.64± 8.17,41.40± 8.78) (P＜0.01).(2) The detecting rate of behavior problems in injury group was also higher than that of the control group (33.33％,7.02％,P＜0.01),OR=6.63,95％ CI =2.09-21.05.Boys of the injury group had higher scores than those in the control group in seven factors (depression,social withdrawn,restlessness,violation of discipline,attack,compel and social problems) (P＜0.05),and girls of the injury group also had higher scores than those in the control group did in three factors (depression,social withdrawn and attack) (P＜0.05).(3) In the injury group,boys had higher scores in the factor of schizoid anxiety than girls did (P＜0.01),risk factors were depression (OR=0.529,95％ CI =0.292-0.959),social withdrawn (OR=2.274,95％ CI =1.311-3.944),restlessness (OR=0.426,95％ CI =0.213-0.852),violation of discipline (OR=0.426,95％ CI =0.213-0.852) and attack (OR=0.644,95％ CI =0.459-0.903).However,girls had higher scores in the factor of depression than boys (P＜0.05),their risk factor was depression (OR=0.573,95％ CI =0.357-0.919).Conclusion There is a certain correlation between tooth injury and their psychological behavior characteristics of children.

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".

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.

OBJECTIVE:To provide reference for breaking the“dual-track”system of the pharmacist and perfecting pharmacist system in China. METHODS:By reviewing laws and regulations relating to the pharmacist in recent 21 years,the implementation and problems of pharmacist system was investigated. RESULTS & CONCLUSIONS:The imperfection and dissonance of pharma-cist management regulations and laws system result in long-term“dual-track”system of pharmacist authentication. There still are other problems such as low rate of pharmacist registration and unbalanced regional distribution;unbalance between national li-censed pharmacist examination and examination condition of health systems pharmacist;divergence and mismatching between phar-macy education pharmacist training;social value of pharmacists cannot be reflected adequately. It is suggested to formulate Regula-tions on the Licensed Pharmacists as soon as possible,establish uniform and standard qualification and title appraisal system for na-tional pharmaceutical professional and technical personnel,promote licensed pharmacist classification registration and examination system reform,strengthen pharmacy education and licensed pharmacist training system reform,guide licensed pharmacist allocation rationally and orderly by various measures and enhance the propaganda of licensed pharmacist and their work,so as to promote the mergence of national licensed pharmacists qualification system and health professional technical pharmacist competence system.

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.

Objective To investigate the value of contrast enhanced ultrasound (CEUS) in diagnosing poor differentiated cholangiocarcinoma. Methods Sonograms of 11 patients with pathologically confirmed poor differentiated cholangiocarcinoma were retrospectively analyzed. The size, boundary, shape, echo, blood distribution and characteristics of the enhancement duration were observed. Results All lesions presented irregular shape (100%), most (9/11, 81.82%) with indefinite boundary, some (6/11, 54.55%) with low echo. No blood flow signal was found in the interior of masses, while grade 1 blood flow signal was detected in periphery of the lesions. Resistance index (RI) was ≥0.6 in spectral Doppler in 7 (63.64%) lesions. Marginal rim-like hyperechoic enhancement in the arterial phase was found without centripetal filling in all 11 patients, marginal rim-like hypoechoic enhancement was observed, but being hyperecho compared with interior part without medium in delayed phase. Conclusion The contrast-enhancement modality of poor differentiated cholangiocarcinoma is characteristic. Combined with two-dimensional ultrasonography and color Doppler ultrasound, the diagnostic rate will be improved.
