简介:目的:探讨广东省兴宁市成为国家性病监测点8年间的5种性病疫情流行病学特征,为今后制定防治对策提供依据。方法:采用描述性流行病学方法对全市19个街道办事处及乡镇5种性病报告病例的“三间分布”进行分析。结果,2007~2014年间兴宁市梅毒、生殖器疱疹及尖锐湿疣报病数逐年增加,生殖道沙眼衣原体报病数早年上升明显,近2年有下降趋势,淋病发病呈现下降趋势。兴田街道办事处(城区)发病率明显高于农村。男性、女性的淋病及生殖器疱疹报告发病率均较低,而梅毒、生殖道沙眼衣原体报告发病率均较高。结论:兴宁市成为国家性病监测点通过高质量监测数据可真实了解不同地区性病感染状况,疫情的变化较真实反映了性病流行情况,未来应进一步加强性病报病网络建设,并应采取综合措施控制性病在本地区的流行。
简介:Objective:AllelicpolymorphismsofCCR5△32、CCR2b-64I,CX3CR1-249I280MandSDF1-3’AassociatedwithHIV-1infectionanddiseaseprogressionwereinvestigatedinindigenousUygurpopulationsfromtheXinjiangUygurAutonomousRegionofChina.Mithods:Thestudypopulationcomprised316healthyUygursubjectswithanagerangeof1-80yearsold,fromwhomwholeperipheralbloodsampleswerecollectedandnonewereHIV-1seropositive.GenomicDNAsampleswerepurifiedusingaQiagenBloodKit.GenotypingoftheaforementionedfouralleleswasperformedusingPCRorPCR/RFLPassay,andfurtherconfirmedbydirectDNAsequencing.Results:TheallelicfrequenciesinChineseUygurpopulationwereasfollows:3.48%forCCR5△32;19.45%forCCR2b-64I;13.8%forCX3CRI-249I280Mhaplotype,and20.41%forSDFI-3’A.MutantalleledistributionsamongUygurpopulationswereinaccordancewiththeHardy-Weinbergequilibrium.NostatisticaldifferencewasfoundbetweenthefrequencyofthethreeHIVcoreceptorsandtheirrespectiveligandgenes.Conclusion:ThefrequencyofSDF1-3’AandCX3CR1-249I280MhaplotypemorecloselymatchedthehanChinese.ThefequencyofCCR5△32inUygurpopulationswasbetweenCaucasianandHanfrequencies,themorecloselymatchingthefrequencyinMedi-Asiapeople.NogeneticlinkagebetweenanytwoofthethreeHIVcoreceptorgeneswasfound,butobviousgeneticlinkagesexistedbetweenCX3CR1-249IandCX3CR1-280M,withevenhigherlinkagedegreesthanCaucasianpeople.
