OBJECTIVEThe aim of this study was to estimate and predict the AIDS epidemic situation in Jiangsu province by using a software named Estimation and Projection Package (EPP) and then to provide accurate information for making control plans and conducting interventions.
METHODSDate were obtained from the comprehensively monitored sentinels of AIDS and venereal diseases (Data were from 28 national monitored stations and 52 provincial stations. From 2003 to 2009, a total of 10 730 000 people had been monitored) as well as project survey and laboratory tests. EPP epidemic model was employed to analyze the prevalence and to predict future epidemic situations.
RESULTSA total of 830 000 and 1 020 000 people were monitored in 2003 and 2004 respectively, and 8 880 000 more people were monitored in the following 5 years. By the end of 2009, a total of 4103 HIV infection cases had been reported, among which 918 people were diagnosed with AIDS and 432 died. Since 2003, the cases infected through IDU had decreased from 66.84% (262/392) to 16.40% (142/868). However, the cases infected through sex contact had increased from 21.68% (85/392) to 77.40% (672/868). Among these cases, homosexual transmission and heterosexual transmission accounted for 39.10% (339/868) and 38.30% (333/868) respectively. It was estimated that there would be 14 290 HIV/AIDS cases in 2011 which is 18.10% (2191/12 099) higher than that in 2009. The estimated HIV infection rate would be 0.02%.
CONCLUSIONEPP prediction showed the AIDS epidemic situation in Jiangsu province had an ascendant trend and the AIDS epidemic situation had demonstrated rapid growth. Therefore, it is necessary to take effective preventive measures to control the spread of AIDS.

This study was aimed to establish an efficient method to detect 10 common MLL fusion genes in patients with acute leukemia. Firstly, the relevant references and databases were searched to thoroughly investigate all fusion breakpoints; the primers and probes were designed according to nearly all the involved fusion types of gene. Then the multiplex real-time PCR system was established and optimized by using the established 16 positive plasmids and negative cell lines. Finally, the detection system was clinically evaluated by means of collected 54 samples of leukemia. The results indicated that the established detection system could efficiently detect all positive plasmids with sensibility to 10 copies. Four kinds of fusion gene types such as MLL-AF4, MLL-AF9, MLL-AF10, MLL-ELL could be detected in 54 samples, the sequencing of positive samples showed consistency of sequencing results with detection results. It is concluded that a novel multiplex real-time PCR detection method is established which can detect 10 common MLL fusion genes covering about 90% of the cases harboring MLL fusions. This method is fast, sensitive, specific and reliable, and should be an useful clinical tool for identification and management of leukemia patients with MLL fusions.

OBJECTIVETo explore dynamic characteristics of the HIV mother to child transmission (MTCT) epidemic in China.
METHODSA deterministic dynamic transmission model was used to determine the effect of key parameters on the likely long-term trends of the HIV MTCT epidemic in China. Matlab 7.0 was used to develop the model.
RESULTSThe number of the susceptibles (S), the transmission rate (β), and the screening proportion (α) of HIV positive pregnant women have the greatest impact on the HIV MTCT epidemic in China. The growth of the MTCT epidemic in China could not be controlled only by decreasing the MTCT transmission rate. The prevalence of HIV positive women should be reduced and more pregnant women should be tested for HIV.
CONCLUSIONPrevention of MTCT (PMTCT) should focus not only on the reduction of HIV transmission rates and incidences of HIV among women but also on the increase of HIV testing for pregnant women. The most cost-effective PMTCT means for China should be investigated in future studies.

Objective To study the quality of life and its influential factors among HIV positive population. Methods Quality of life was evaluated among 2608 HIV positive population by WHOQOL (Chinese Version) to calculate the total and four domains' scores of quality of life. Multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains and the total score of quality of life. Results Physical,psychological,social,environmental and the total scores of the HIV positive population were 12.96±1.94,11.79± 1.19,13.79±2.44,12.40±1.93 and 51.02±6.03,respectively. Females had a higher scores than males in the four domains and the total score of quality of life. Through a multiple linear regression model,we found that the influential factors would include gender,age,occupation,family conflict and appetite etc. Conclusion People living with HIV had higher scores in social domain,but lower scores in psychological domain,suggesting that psychological intervention should he strengthened.
