Salazopyrin in the treatment of scleroderma

Following reports of successful treatment of various forms of scleroderma with salazopyrin, 13 selected patients were treated, 8 with acrosclerosis, one with sclerodermatomyositis and four with generalized morphoea. No effect was observed except in two cases of generalized morphoea which were in the acute stage of spreading to involve most of body surface. These two were more or less cured. This observation seems to warrant further trials with salazopyrin in this rare but serious form of scleroderma.     

胃癌患者外周血中CK-19的表达及其临床意义

目的检测胃癌患者外周血中CK－19和MUC－1的表达,确定其作为早期胃癌微转移分子标志物的可能性;讨论CK—19mRNA对早期胃癌微转移的临床诊断意义。方法研究对象共分为三组,其中2009年3月～2012年3月期间于陕西省安康市中心医院住院的96例初治胃癌患者作为实验组．30例胃良性疾病患者和30例健康人的外周血分别作为对照组。采用RT—PCR法检测实验组及对照组的外周血中CK－19tuRNA及MUC～1mRNA的表达情况并评估目的基闪的表达与临床特征的相关性,对结果进行统计学分析．选取也合适的标本进行PT－QPCR实验。RT—QPCR法检测44例早期胃癌患者外周血中CK－19mRNA的表达量,通过绘制ROC曲线．探索诊断效果最好的临界值并计算AUC。结果①实验组和埘照组中CK－19mRNA阳性表达牢分别为53．13％（51／96）、1．67％（1／60）．差异有高度统计学意义（P〈0．01）,且胃癌组中CK－19mRNA的阳件表达与肿瘤分期和和分化程度有关;胃癌组和对照组中MUC－1mRNA阳性表达率分别为61．46％（59／96）、51．67％（31／60）,差异无统计‘学意义（P〉0．05）。②本实验结果统计的临界值为0．2358,灵敏度为95．45％,准确度为77．37％;AUC为0．897。结论RT—QPCR法检测外周血中的CK－19mRNA,适合作为诊断早期胃癌微转移的重要参考指标。
