RESUMEN
@#目前，针对肿瘤治疗药物在体内应用中的局限性，出现了许多高效的药物递送系统的研究，其中纳米药物载体技术和 细胞药物载体技术较为热门，并取得了许多成果。纳米药物载体具有的优点，如防止药物发生降解及灭活，增加药物的靶向性， 降低药物的毒副作用，可量产等。细胞载体更是利用细胞本身固有的特性，具有主动靶向肿瘤部位、低免疫原性和穿过体内生理 屏障等优点，在药物递送研究中有广阔的应用前景，但是仍然存在很多问题及不足。研究人员创造性地将两者结合，使他们的优 势互补，极大地强化了递送药的效率，增加了体内靶向性，降低了周围组织的细胞毒性等。本文从近几年来细胞-纳米药物载体 系统研究的文献中，总结了红细胞、干细胞、单核/巨噬细胞、 T细胞、树突状细胞（dendritic cell，DC）等作为纳米药物细胞载体的优 缺点及目前的应用现状。
RESUMEN
@#Objective To investigate the prevalence and related factors of primary palmar hyperhidrosis in adolescents in Yangzhou. Methods On-site questionnaire survey was performed on students selected by cluster random sampling from the two colleges and two high or middle schools, with each class as a unit. Data were collected through the questionnaire to make the diagnosis and severity grading. Results A total of 3 487 copies of the questionnaire were distributed in the survey and 3 299 were finished, among which 3 083 were effective with an effective rate of 88.41%. Among them, 1 358 respondents were males and 1 725 were females; 933 were middle school students, 809 high school students, and the remaining 1 341 college students. According to the diagnostic criteria, 104 respondents were diagnosed with palmar hyperhidrosis with an overall prevalence of 3.37%. There were 60 (4.41%) males and 44 (2.55%) females. Although the prevalence of palmar hyperhidrosis in males was higher than that of females (χ2=8.130，P<0.05), severe palmar hyperhidrosis was more often to be observed in females than in males, and females were also more likely to have hyperhidrosis in other parts of the body. In addition, the age of the first onset of the disease was mainly 10 to 20 years old and 36.54% of the patients had a family history. Conclusion The prevalence of palmar hyperhidrosis in adolescents in Yangzhou was 3.37%, and there is a significant difference in the gender. The palmar hyperhidros is often accompanied by hyperhidrosis symptoms of other parts of body, and the disease shows an obvious genetic predisposition.
