1广东省静脉吸毒者吸毒行为和性行为特征研究显示文摘目的 了解广东省艾滋病(AIDS)高危地区静脉吸毒者(IDUs)吸毒行为和性行为特征,为进一步的HIV/AIDS预防干预研究提供建议.方法 于2002年8月至2004年3月,对200名戒毒所内的静脉吸毒者进行面对面问卷调查.结果 200名IDUs年龄为20~29岁(53.0%),无业(42.5%),男性(83.5%),汉族(96.5%),初中及以下文化程度(86.5%).入所前30天使用的主要毒品是海洛因(99.5%),54%的人有多药滥用.首次吸毒年龄平均为22.79±4.87岁.注射过程中各种共用行为比率为22.0%~33.5%,79.4%的人经常重复使用一支针具.29.2%的人有多性伴,与固定和临时性伴性交从不使用安全套的比率分别为67.3%、25.7%.30%的女性有过以性换钱和换毒品行为,29.2%的男性有花钱买性服务.结论 广东省静脉吸毒者HIV感染相关危险行为普遍存在,包括直接和间接的针具共用行为及危险性行为.应进一步开展危险行为的形成与降低原因的研究,并针对特定的高危行为采取合理的预防干预措施.林鹏 付笑冰 李江虹 王晔 钟文龙 Merrill Singer Michael Duke 许锐恒 杨放 刘勇鹰 赵茜茜 何群 孙宝山 陈茂于 范湛丽 黄丽英 2006中国艾滋病性病2006,12,2:19

3Fractal analysis of retinal vasculature in normal subjects on ultra-wide field fluorescein angiography显示文摘AIM: To evaluate the fractal feature of the retinal vasculature of normal eyes on a stereographic projected and montaged ultra-wide field(UWF) fluorescein angiography(FA).METHODS: Prospective, observational, cross-sectional study. Totally 59 eyes of 31 normal subjects were imaged using the Optos 200 Tx. Images obtained at different gaze angles stereographically projected and montaged. The early-phase UWF FA frames were processed to segment the retinal vasculature and the results were exported as binary masks. The fractal dimension(FD) was calculated using the box-counting method.RESULTS: The global FD for the entire retina was 1.6±0.04, with no difference between males and females(1.59±0.04 vs 1.61±0.04, P=0.084) or between right and left eyes(1.6±0.04 vs 1.6±0.05, P=0.61). FD was nonuniformly distributed among four quadrants(P<0.001) and decreased as the distance from the fovea increased(P<0.001). A negative association was observed between FD and age(R=-0.37, P=0.006), and this relationship was observed in the posterior and mid-peripheral retina(P<0.05) but absent in far-periphery(P>0.05).CONCLUSION: Fractal geometry is non-uniformly distributed across the retina in normal eyes and decreases from the fovea to the far-periphery. Subjects with an older age tend to have a smaller FD, however, the FD in the farperiphery does not appear to be influenced by age.Wen-Ying Fan Alan Fleming Gavin Robertson Akihito Uji Jano van Hemert Michael Singer Min Sagong Michael Ip SriniVas R.Sadda 2020International Journal of Ophthalmology(English edition)2020,13,7:3
