ABSTRACT
The position of roles and requirements of professional competency in foreign medical librarians were ana-lyzed in order to provide the experiences of foreign medical librarians for the professional development of domestic medical librarians,which showed that medical librarians play their roles in health information service,health literacy education,scientific research,teaching,clinical decision-making support and public health service, and that their role and competency have been recognized by medical experts and health information users. Medical librarians should not only possess the competency of communication,systematic review,resource evaluation,organization and manage-ment and health management but also the proficiency in teaching and the ability to promote the development of health information industry,which will thus help them to become a health informationist or a clinical information expert.
ABSTRACT
Objective To explore the relationship between serum anti - cardiolipin antibodies( ACA ) and recurrent cerebral infarction( RCI),and to provide the clinical evidence for the prevention and treatment of RCI. Methods One hundred and ten patients with RCI,120 patients with primary cerebral infarction( PCI)and 150 healthy controls were recruited. Serum ACA was detected using quantitative enzyme linked immunosorbent assay( ELISA)and the positive rate of ACA was compared between these three patient groups. Results The positive rate of serum ACA of RCI group (31. 82%)was higher than that of PCI group( 15. 00%)( P <0. 05 ). Compared with patients above 50 years old (11. 56%),the patients under age of 50 had a higher positive rate of ACA( 57. 89%)( P <0. 05 ). There was no significant difference between males( 22. 52%)and females( 23. 53%) in positive rate of ACA( P > 0. 05 ). The recurrence rate(56. 25%)of ACA positive patients was higher than that of ACA negative patients(29. 79%)after one year follow up(P<0. 05). Conclusion Higher positive rate of serum ACA is observed in RCI patients. The PCI patients with high positive rate of serum ACA has an increased susceptibility for RCI. ACA detection is important for prediction and clinical intervention of the recurrence of cerebral infarction.
