Considering a variety of theories such like Dunkin's, Centra's and Kolitch's, a set of 13 indicators are designed to evaluate effect of courses taken in high education of China currently, compro-mised by chief aspects of course designing, practicing, and effect. Three courses including medical nursing, humanistic cultivation and communication skills in nursing and fundamentals of nursing in a nursing de-partment are chosen to be objects of questionnaire survey about the above indicators. The results show that there are significant differences in curriculum effectiveness between different courses. The scores are 2.81, 2.80 and 2.60 respectively, and teachers and students have different evaluation on the same indicators of the same curriculum,which provides a reference for teachers, colleges and universities and teaching management departments to promote the improvement of teaching quality.

Functional constipation(FC) in childhood is characterized by a low defecation frequency in combination with either involuntary loss of stools(encopresis),passage of large amounts of stool,retentive posturing,or hard and often painful defecation.It represents 3%-5% of general pediatric outpatient visits and up to 25% of pediatric gastroenterology consultations.FC is a diagnosis made by history and physical examination.No testing is necessary or desirable.The decision to seek medical care for symptoms arises from a parent′s or caretaker′s concern for children.The caretaker′s threshold for concern varies with his or her experiences and expectations,coping style,and perception of illness,till now there is not an universal native criteria established in spite of much has been done in it.The criteria used are still to draw assistance from the foreign standard,among which the classic criteria,the Rome Ⅱ and Rome Ⅲ criteria are considered commonly used.The purpose of this paper is to descript the several foreign criteria,and to make comparison among them,and to explore their applicability and effectiveness in childhood FC

Objectives: To assess the feasibility and stability of right ventricular outflow tract (ROVT) pacing under current technology by comparing the results of ROVT pacing with the traditional right ventricular apex (RVA) pacing. Methods: A total of 42 patients (at mean age of 63.5±10.4 years) without structural heart disease were randomly divided into two groups. RVA pacing group (n=14),and RVOT pacing group(n=28). An active fixation lead was implanted in all patients whose pacemaker could automatically measure the pacing threshold every day. The operation time,X-ray exposure time and lead parameters detected during the operation were collected to evaluate the feasibility of RVOT pacing. The complications related to lead and implantation procedure and the trend of threshold change during the follow-up time were used to assess the stability of RVOT pacing.Results: There were no statistic differences between RVA pacing group and RVOT pacing group in terms of operation time,X-ray exposure time and lead parameters. In RVOT group,the change of threshold during acute period was similar to those in RVA group (P=0.23). Chronic pacing threshold was also comparable between two groups,mean threshold at 6 months follow-up time was 0.55±0.11V and 0.54±0.09V at 0.4 pulse width in RVA group and RVOT group respectively (P=0.787).Conclusion: RVOT pacing was feasible and stable in operation time and lead characteristics compared with the conventional RVA pacing under current pacing technology.
