Methods： STD case-reporting data collected from 43 counties and districts in Chongqing from 1998 to 2003 were analyzed with STD Data Management Software and Excel Software. Results： A total of 133,323 cases of eight different STDs were reported from 1998-2003. The annual incidence of all eight STDs combined was 71.89/10^5.Generally, reported cases and incidence have decreased since 2001. Although gonorrhoea diagnoses made up a significant proportion of the STD burden, this proportion decreased annually. The proportion of the STD burden attributed to Condyloma accuminatum （CA） was always above 30 percent. The proportions of non-gonoccocal urethritis, genital herpes and syphilis within the combinedSTD burden increased gradually from 1998 to 2003.Reported cases of HIV increased rapidly over this time. A total of 214 HIV cases were reported from 1998 to 2003,the majority of which were among men. For HIV, the maleto-female ratio was 1.17, but CA was found among more women than men. Incidence for all STDs was highest among 20-39 year olds, who accounted for 72.2% of reported infections. The majority of STDs were transmitted through extra-marital intercourse,accounting for 55.3%. Conclusion： The STD epidemic in Chongqing changed from 1998-2003. STD incidence declined, as a result of various factors. The epidemiology of STDs has changed.HIV incidence has increased rapidly. This indicates that the AIDS epidemic has reached a critical period. The results of this study suggest a need for readjusting control measures and redistributing health resources.展开更多

Especially the young, born after the 1980s, will play an important part in the future housing market. So it seems quite urgem to effectively satisfy the housing needs of young people. Massive research and practices indicate that the housing industrialization conserves the environment, improves quality and reduces cost of housing and is among the most effective ways to boost sustainable development of housing industry. The main objective of the paper is to discuss how to meet the growing housing demands of the young and concludes that housing with recreation, sports and other ancillary facilities will be better fit to the young to rent or to own. Furthermore, an analysis of the Chongqing housing market potential of young people＇s wish to rent or to purchase satisfactory housing demonstrates that some real estate investors may be failing to exploit serious opportunities that could arise from providing service to the young. And this case study of meeting the changing housing needs of the young may help accelerate the process of housing industrialization in Chongqing as well as providing a useful study concerning housing industry.展开更多
