To investigate the epidemic of HIV, HCV and syphilis, HIV-1 subtype among men who have sex with men (MSM) and to measure factors that correlated with sexual transmitted infections (STIs), a cross-sectional survey was conducted among 657 MSM in Zhenjiang, Jiangsu, during 2012-2013. Social-demographic characterization and risky behaviors were collected and blood samples were obtained. In this survey, the prevalence of STIs of HIV (5.3%), HCV (0.6%) and syphilis (19.2%) were measured. Of 35 HIV-infected MSM, 1 (0.2%) and 17 (2.6%) were co-infected with HCV and syphilis. Among 33 samples with available HIV-1 genomic fragments sequences, 6.1% B, 72.7% CRF01_AE and 21.2% CRF07_BC were indentified. Multivariate logistic regression analysis showed that age>30 years (OR 2.002; 95% CI 1.144 to 3.502) and having had STIs symptoms in the past year (OR 11.673; 95% CI 3.092 to 44.078) were positively correlated with STIs positive, while consistently use condom when have sex with male partners (OR 0.621; 95% CI 0.408 to 0.945) was significantly associated with a low STIs rate. The worsening epidemic of HIV, HCV and syphilis, complex subtypes of HIV-1 and risk factors suggest that effective intervention strategies should be strengthened for MSM in Zhenjiang, Jiangsu.

The image-to-image translation aims to learn a mapping between the source and target domains. For improving visual quality, the majority of previous works adopt multi-stage techniques to refine coarse results in a progressive manner. In this work, we present a novel approach for generating plausible details by only introducing a group of intermediate supervisions without cascading multiple stages. Specifically, we propose a Laplacian Pyramid Transformation Generative Adversarial Network (LapTransGAN) to simultaneously transform components in different frequencies from the source domain to the target domain within only one stage. Hierarchical perceptual and gradient penalization are utilized for learning consistent semantic structures and details at each pyramid level. The proposed model is evaluated based on various metrics, including the similarity in feature maps, reconstruction quality, segmentation accuracy, similarity in details, and qualitative appearances. Our experiments show that LapTransGAN can achieve a much better quantitative performance than both the supervised pix2pix model and the unsupervised CycleGAN model. Comprehensive ablation experiments are conducted to study the contribution of each component.
