Objective: To explore the methods of establishing and maintaining community injecting drug user (IDU) cohort. Methods: From June 2014 to June 2017, a community survey was conducted on basis of local needle and syringe exchange site to recruit 200 HIV sero-negative IDU for a prospective cohort study in Longyang district of Baoshan city, Yunan province. Follow-up was carried out every six month to investigate high risk drug use behavior and sexual behavior, and blood samples were collected from them for the tests of HIV and HCV serum antibodies. The cohort would be opened every 12 months to replenish the cohort to 200 subjects. Results: The follow up was conducted for 3 years in 229 IDUs. Cohort follow-up rate was 93.0% (213/229) for 6 months, 92.1% (211/229) for 12 months, 91.7% (200/218) for 18 months, 87.2% (190/218) for 24 months, 86.0% (172/200) for 30 months and 86.0% (172/200) for 36 months. Conclusion The community IDU cohort has a high follow-up rate.

Classic problem-based learning ( PBL ) was applied in a medical microbiology course.The results of questionnaire survey showed most of the students were satisfied with the whole learning program.They thought the case was appropriate,and the discussing could increase their understanding of the knowledge.Based on the problems faced during the application and the students' feedback,the duty of the tutors,summary of the learning topic,arrangement of the course,application of different teaching methods,and selection of the tutors were discussed in detail.

Guangdong Province,with its rapid economic development,is one of the fastest provinces of china in the progress of urbanization,while its rural development is relatively laged.The main reason of this phenomenon is: the government paid too much attention to the city,but the investment in human capital to the rural areas is insufficient.In this paper,the reason for the phenomenon is briefly analyzed.

In order to strengthen the education for university students’all-round devel-opment,and to improve the quality of teaching,Shantou University,by making good use of higher education resources,built a digital campus consisting of virtual classrooms based on advantage of computer and Internet network environment,and plenty of general education programs were carried out.The teaching practice showed that virtual classroom,as a network platform,played an important role in general education programs.

In order to meet the modern needs in medical talent education and bring up highly qualitfied medical talent,Medical College of Shantou University has aggressively and effectively conducted exploration and practice on high medical education,and developed a new teaching model for bringing up medical talent under with high quality the strategies of "Reform of Course System" and "Innovation of Teaching Model".The new teaching model is designed to bring up excellent clinicians with innovative spirit and proficient basic skills.It keeps up with the global ideal of high medical education,and it is an originated teaching model in China with Chinese characteristics and a unique style of Medical College of Shantou University,which will make a positive and significant impact on Chinese high medical education.

This article summarizes the virtual reality(VR) technology's bases and characters and discusses the application scope of VR in modern medicine thoroughly.For example,the application of VR in digitized virtual human,the simulation of surgical operation,long-distance medical diagnosis,virtual hospital,higher medical education technology and so on.It also covers the existing problems and prospect of VR.

It is necessary to pay attention to the quality of mass higher education.We should adapt the evaluation system of higher education to the needs of its managerial system reform and healthy development.The cognition of that can help us to build higher education evaluation system with Chinese characteristics,which not only fits the national condition but also reflects the general rules of this system.

Innovative education on business venturing at medical colleges and universities is a need of both the time of knowledge economy and the socialization of medicine.Innovative venturing education is a new model to cultiv ate high-caliber medical talents with wide social perspective,profound knowledge,creativity and entrepreneurship.Approaches to implementing such education in the transition of educational model may include enhancing cultural and sociological education,promulgating venturing practices in medical field,establishing favorable at mosphere for innovative venturing education,fostering English language skills in the whole process,emphasizing clinical practices,setting up effective competency assessment system and establishing a high-caliber faculty team.

Ongoing and rapid development in medical science makes the improvement of English language abilities crucial for students. The paper sets out now to:develop excellent teaching methods, form a qualified and dedicated teaching faculty, focus on individual teaching methods, make English interesting and popular among students, and manage the process to maximize the value of the investment.
