RESUMEN
CD47 is a transmembrane protein widely expressed on cell surface, which is considered as a key molecule for immune escape. With an increasing number of related studies, the role of CD47 and its ligands in immunomodulatory effects has been gradually understood. Recent studies have investigated the role of CD47 in ischemia-reperfusion injury of allogenetic kidney transplantation, rejection and xenotransplantation. Nevertheless, the specific role and the key mechanism remain elusive. In this article, the structure and function of CD47, common CD47 ligands, the relationship between CD47 and kidney transplantation, and the application of CD47 in kidney transplantation were reviewed, the latest research progress of CD47 in kidney transplantation was summarized, and the limitations of current research and subsequent research direction were analyzed, aiming to provide reference for subsequent application of CD47 in allogeneic and kidney xenotransplantation.
RESUMEN
Objective To understand the dynamics of the treatment and outcomes of advanced schistosomiasis patients in Qianjiang City so as to provide the evidence for improving the future work. Methods All advanced schistosomiasis patients were investigated in Qianjiang City during the period of 2009-2013. Results Totally 1 284 person?times of advanced schistoso?miasis patients received the treatment. The rate of clinical improved was 89.88% and 82 patients were cured. The type of asci?tes was the majority and the megalosplenia type was the second. Conclusion The prevalence of advanced schistosomiasis showed a decreasing tendency but the incidence of new advanced schistosomiasis patients showed a slightly increasing.
RESUMEN
Objective To evaluate the protective effect of Fangyouling extracted from herb on Schistosoma japonicum in-fection in the field. Methods The residents in 2 villages Zhaonao Village and Miaochang Village were divided into Group A 139 persons and Group B 162 persons and the residents in Group A embrocated Fangyouling before their contacting the in-fested water and the residents in Group B did not. All the residents were investigated with questionnaires and received the blood and stool examinations for schistosomiasis. Results The positive rates of blood tests were 3.13%and 9.34%in Group A and Group B respectively, the positive rates of stool examinations were 1.92%and 6.44%in Group A and Group B respectively both P values<0.05 . Conclusion Fangyouling has a good protective effect on S. japonicum infection.
