流行病学

BACKGROUND: Epidemiological evidence has suggested a link between beta(2)-agonists and increases in asthma mortality.

Besides, I also surely know that just professional skills are not enough for being a good doctor. Hence, I attend the basic scientific research of preclinical medical college, the epidemiological investigation of public health college and the clinical scientific research of clinic college,from which I possess of some experimental skill such as CELL CULTER , PCR , Western blotting and so on.Above all,these experience cultivate my ability of designing the experiment and enforcing the experiment,which help me complete my research.

做为一名七年制的学生，学校对我们的要求是&临床技能和科研能力同等重要&因此在进行临床技能培养的同时，我先后参加过我校基础医学院的基础科研实践、公共卫生学院的流行病学调查实习，及临床学院的临床科研实践，让我熟练掌握了细胞培养、 PCR 、 Western blotting 等分子生物学技术；最重要的是，这些实践经验培养了我独立完成从研究课题的设计到实验方案的实施能力，帮助我顺利的完成了我在硕士期间的科研项目。

Principal current research topics include air pollution, endocrine disrupters, epidemiology, food and diet, and risk assessment.

Through reviewing the reproductive toxicity of some major environmental chemical pollutants, including endocrine disrupters, organic phosphor and chlorine pesticides, organic solvents, and some metals such as lead, cadmium, mercury, manganese, the paper finds that all these ECPs have different extents of toxic effects to experimental auimals on procreation, gestation and even on offspring, some of which have been evidenced by the population epidemiological studies.

本文通过对邻苯二甲酸酯类和双酚A等内分泌干扰物、有机磷和有机氯农药、常用有机溶剂以及常见金属的生殖毒性研究的综述，发现它们均在不同程度上造成对实验动物的生殖毒性、妊娠毒性以及对子代的毒性影响，其中部分在人群流行病学研究上得到证实。
