The occurrence of intrauterine growth restriction (IUGR) may be related to maternal malnutrition, abnormal placental function, immune abnormalities, genetically related problems as well as other diseases, but the mechanism is still unclear. Therefore, the study of IUGR and the development of its animal model are critical issues in obstetrics. IUGR models are mainly based on laboratory rodents, such as mice and rats, and other mammals such as pigs, rabbits and sheep. This article introduced several common IUGR animal models, including nutrition restriction model, high-altitude pregnancy model, natural selection model, and nicotine exposure model, and also described the construction methods of IUGR models and the comparison of their advantages and disadvantages.

The Chinese national college students' life science competition has been held for three times, with good organization, large scale and high participation degree. The competition plays an important role in promoting life science education and research. This paper reports the form and status of the competition, statistically analyses the registration data and competition results by region and year, based on the previous three competitions. By combining new changes and understanding in the field of life science, we also indicate prospects on how to better promote the competition.

Synthetic biology is a fast moving interdisciplinary branch of biology and engineering. To educate the next generation of synthetic biology scientists, the International Genetically Engineered Machine (iGEM) competition was established. In the past eleven years, many Chinese teams have participated in this event, but no thorough review and analysis have been carried out. In this paper, we collected the data and information of the Chinese teams from the iGEM website and analyzed the number, distribution and performance of Chinese teams in iGEM competition. We also described contributions made by the Conference of China iGEMer Community (CCiC) organization. The contributions to China higher education made by the iGEM competition were also summarized. Finally, we proposed several suggestions for the development of the iGEM competition in China. We envision the iGEM competition will continue to promote the innovative education and cultivation of the next-generation synthetic biology scientists in China.
