Sexually transmitted infection prevalence and related risk factors among heterosexual male methamphetamine users in China
No full text Few studies have examined the association between methamphetamine (MA) abuse and sexually transmitted infection (STI) risk among heterosexual male MA users in China. A total of 288 heterosexual male MA users who met our inclusion criteria were recruited from nightclubs, KTVs, bars, bath centres and an STI clinic. STIs were screened among the participants, and the risk factors related to STIs were analysed by multivariate logistic regression in SPSS 11.0. Among the 288 heterosexual male MA users, 51 (17.7%) had syphilis, 36 (12.5%) had genital warts, 2 (0.7%) had genital herpes, 3 (1.0%) had HIV infection and 41 (14.2%) had urethritis. STIs were associated with the following variates: ‘MA has the function of anti-inebriation’ (OR = 2.522, 95%CI = 1.337–4.756), ‘I am addicted to MA’ (OR = 4.030, 95%CI = 2.194–7.401), ‘It occurred to me to abstain from MA’ (OR = 2.939, 95%CI = 1.246–6.934), ‘Years of MA abuse’ (OR = 2.622, 95%CI = 1.318–5.215), ‘Times of MA abuse per week’ (OR = 5.275, 95%CI = 1.988–14.002), ‘Number of persons using MA together’ (OR = 2.579, 95%CI = 1.246–5.340) and ‘Number of female sex workers as sex partners per MA abuse’ (OR = 4.004, 95%CI = 1.526–10.508). Our findings show that MA users belong to the high-risk group for STI in China. STIs, except for HIV, have spread widely among heterosexual male MA users. Thus, specific interventions must be conducted to prevent the spread of STIs in this population in China. </jats:p
Preparation of Micro Gold Devices on Poly(dimethylsiloxane) Chips with Region-Selective Electroless Plating
No full textA novel protocol for fabrication of micro gold devices on poly(dimethylsiloxane) (PDMS) substrates was developed on the basis of region-selective electroless plating. The layout of a micro gold device was first photochemically patterned onto the PDMS surface through a UV induced poly(acrylic acid) (PAA) grafting process. The carboxylic moieties on the grafted PAA served as the scaffold for a series of wet chemical reactions that led to the immobilization of gold nanoparticles in the UV-exposed region, where electroless plating then occurred under the catalysis of the nanoparticles. Gold devices fabricated with such a protocol could tolerate the Scotch tape test and survive in a repeated bending-straightening test. They also showed good stability in acidic and alkaline solutions, possessed almost the same electrochemical properties as a standard gold disk electrode, and allowed thiol-compounds to form a perfect self-assembled monolayer on their surfaces. The fabricated micro gold electrode was demonstrated to be suitable as the integrated amperometric detection element in a full PDMS micro electrophoresis chip
