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.
简介:目的观察龙牡汤治疗血虚风燥型特应性皮炎的临床疗效、安全性及对患者生活质量的改善情况、复发情况。方法采用随机对照方法将64例患者随机分配到试验组(龙牡汤内服加外洗组)和对照组(氯雷他定片和丁酸氢化可的松乳膏组),疗程8周。于治疗前、治疗第2周、第4周、第8周记录皮肤病变面积、皮损严重程度、瘙瘁及患者的生活质量、用药情况、不良反应等,并在疗程结束后第3、6个月记录复发情况。结果试验组治疗前后症状体征积分比较有显著性差异,与对照组疗效相当;两组治疗前后生活质量评分比较无显著性差异;两组复发情况比较差异有显著性,对照组6个月的复发风险是试验组的3.14倍。结论龙牡汤内外合治特应性皮炎,有一定临床疗效。
