Objective:
To understand the basic characteristics, sexual behavior and the use of recreational new drugs of young men who have sex with men (MSM) in Tianjin, and to explore the characteristics of young MSM who use recreational drugs, so as to provide reference for the policy making of HIV/AIDS prevention and control in universities.
Methods:
From January 1, 2018, solstice to December 31, 2018, participants were recruited in the bathrooms, bars and social network sites in Tianjin by snowball sampling. The basic demographic information, sexual behavior and recreational drug use of the participants were collected through face to face interviews and questionnaires. Logistic regression was used to analyzed the characteristic differences drug users and non users among young MSM.
Results:
A total of 826 young MSM were included in the study, 32 were infected with HIV, and the overall prevalence rate was 3.87 %. Totally 371 (44.92%) were drug users. Rush Poppers were the most common used drug ( 98.65 %). Of the young MSM using new drugs, 306 (82.48%) multiple drugs were used, 65 people ( 17.52 %) only one drug has been used. Among new drug users, multiple drug users had higher HIV prevalence rate (16.92%) than single drug users (4.57%). There were statistically significant differences between drug users and non users in age, age of first sexual behavior, household registration, sexual orientation, education level, sexual partners seeking routes, unprotected anal intercourse and HIV testing history( OR=3.70,5.51,0.51,0.60,4.64,0.40,0.52,1.98,2.29,P <0.05).
Conclusion
The utilization rate of recreational drugs among young MSM in Tianjin was high. Relevant departments should strengthen the propaganda of recreational drugs and HIV prevention among college students, improve the sexual health awareness of young MSM, and establish a long term HIV and recreational drug prevention system.

Microsatellites or simple sequence repeats (SSRs) have been found in most organisms during the last decade. Since large-scale sequences are being generated, especially those that can be used to search for microsatellites, the development of these markers is getting more convenient. Keeping SSRs in viewing the importance of the application, available CDS (coding sequences) or ESTs (expressed sequence tags) of some eukaryotic species were used to study the frequency and density of various types of microsatellites. On the basis of surveying CDS or EST sequences amounting to 66.6 Mb in silkworm, 37.2 Mb in fly, 20.8 Mb in mosquito, 60.0 Mb in mouse, 34.9 Mb in zebrafish and 33.5 Mb in Caenorhabditis elegans, the frequency of SSRs was 1/1.00 Kb in silkworm, 1/0.77 Kb in fly, 1/1.03 Kb in mosquito, 1/1.21 Kb in mouse, 1/1.25 Kb in zebrafish and 1/1.38 Kb in C. elegans. The overall average SSR frequency of these species is 1/1.07 Kb. Hexanucleotide repeats (64.5%-76.6%) are the most abundant class of SSR in the investigated species, followed by trimeric, dimeric, tetrameric, monomeric and pentameric repeats. Furthermore, the A-rich repeats are predominant in each type of SSRs, whereas G-rich repeats are rare in the coding regions.
