简介:目的:研究组织蛋白酶G(cathepsinG)在慢性自发性荨麻疹患者血清中的表达变化,并初步探讨其作用。方法:纳入30例就诊前未经治疗的慢性自发性荨麻疹患者,设为观察组;另纳入30例健康体检者作为对照组。ELISA法检测两组血清中cathepsinG表达水平并进行比较。结果:对照组血清中cathepsinG浓度为(32.2±12.3)ng/mL,慢性自发性荨麻疹患者血清中cathepsinG浓度上调为(260.4±26.9)ng/mL,差异有统计学意义(t=42.26,P〈0.01)。结论:慢性自发性荨麻疹患者血清cathepsinG表达明显上调,其可能通过与多种细胞因子及炎症介质相互作用,参与慢性自发性荨麻疹的发病机制。

简介:目的观察2%酮康唑洗剂对炎热地区部队特发性瘙痒症患者疗效及生活质量的影响。方法将确诊为特发性瘙痒症的165例患者随机分为3组,试验组69例,给予2%酮康唑洗剂联合咪唑斯汀治疗,对照组56例,给予咪唑斯汀单用治疗,安慰剂组40例,给予安慰剂联用咪唑斯汀治疗;疗程均为4周,于治疗前及治疗后第4、8周进行随访。瘙痒程度采用视觉模拟量表(VAS)评定,并根据症状积分下降指数进行整体疗效评估;利用皮肤病生活质量指数(DLQI)调查问卷评价患者生活质量改善情况。结果治疗前3组患者症状积分、DLQI积分差异无统计学意义;治疗4周结束时,试验组有效率为65.22%,对照组为62.50%,安慰剂组为65.00%;3组均比治疗前有显著改善(P〈0.05);而组间差异无统计学意义(P〉0.05);3组DLQI评分较治疗前均下降,但各组之间差异无统计学意义(P〉0.05)。治疗后第8周,试验组有效率(50.72%)显著高于对照组(21.43%)和安慰剂组(20.00%),差异均有统计学意义(P〈0.01);3组DLQI评分均较治疗结束时增高,但试验组DLQI评分低于对照组和安慰剂组,差异有统计学意义(P〈0.05)。结论2%酮康唑洗剂联合咪唑斯汀能有效改善慢性特发性瘙痒症患者的远期症状,同时能提高患者的生活质量。
