ABSTRACT
Paraganglioma (PGL) is a rare neuroendocrine tumor that causes endocrine hypertension. All paragangliomas had metastatic potential. The 5-year survival rate of patients with metastatic paraganglioma is less than 50%, and the treatment is a big problem. Metastatic PGL has a high specific uptake of iodine [ 131I]-meta-iodobenzylguanidine ( 131I-MIBG), so the treatment is effective, well tolerated, and has few adverse reactions. However, there is a lack of relevant detailed clinical diagnosis and treatment data in China. This article reports the diagnosis and treatment of a case of multi-site metastatic paraganglioma with multiple courses of 131I-MIBG, and discusses the efficacy, safety and tolerance of the treatment for clinical reference.
ABSTRACT
Objective To explore cognition level on nuclear and radiation in Beijing high school students,which may provide evidence for promoting science popularization on nuclear and radiation.Methods Questionnaire-based survey was conducted in Beijing high school students,randomized cluster sampling was used to recruit study participants.Demographic information was collected,and cognition level on nuclear and radiation was evaluated by questionnaire.Results A total of 1 029 pieces of eligible questionnaires were collected.The correct rate for answering common sense about nuclear and radiation was 58％,with score of boys significantly higher than that of girls (t =4.131,P ＜0.05).About subjective cognition of nuclear and radiation knowledge,87 (8.5％) indicated ' quite clear',779 (75.7％) indicated 'know a little',163 (15.8％) indicated 'know nothing'.There was significant difference in score of common sense about nuclear and radiation among people with various subjective cognition level of nuclear and radiation (J-T =8.279,P ＜0.05).There was a linear correlation between support degree for nuclear power and subjective cognition level of nuclear and radiation (r =0.161,P ＜0.05).There was significant difference in score of common sense about nuclear and radiation among people with various support degree for nuclear power (J-T =7.508,P ＜0.05),whereas those who had got high scores tended to support nuclear power to a higher degree.Conclutions Students knew little about knowledge on nuclear and radiation.It is necessary to strengthen propaganda and education on nuclear and radiation,which may help enhance the students' comprehensive quality,and sustainable expansion of nuclear power more support in the long run.
