紫铜消白方联合泼尼松片治疗白癜风55 例临床观察

目的：观察紫铜消白方联合泼尼松片治疗白癜风的临床疗效。方法：将110 例白癜风患者随机分为治疗组和对照组,每组各55 例。对照组采用泼尼松片治疗,治疗组在此基础上加用紫铜消白方治疗,疗程均为3个月。观察比较2组综合疗效,T淋巴细胞指标（CD4⁺、CD8⁺、CD4⁺/CD8⁺）水平,免疫功能指标［免疫球蛋白A（IgA）、免疫球蛋白G（IgG）、免疫球蛋白M（IgM）］水平,皮肤病生活质量指数(DLQI)评分及不良反应发生情况。结果：总有效率治疗组为94.55%（52/55）,对照组为81.82%（45/55）,组间比较,差异有统计学意义（P<0.05）。2组T淋巴细胞指标水平、免疫球蛋白指标水平、DLQI评分治疗前后组内比较及治疗后组间比较,差异均有统计学意义（P<0.05或P<0.01）。药物不良反应发生率治疗组为3.64%（2/55）,低于对照组的14.55%（8/55）,差异有统计学意义（P<0.05）。结论：紫铜消白方联合泼尼松片治疗白癜风能够提高临床疗效,改善患者免疫功能和生活质量,且不良反应少,值得临床推广应用。     

Tectonogeochemical features and metallogenic prognosis in the Xiaolongtan copper mining district, Binchuan, Yunnan Province, China

The Xiaolongtan copper mining district is an important area in Dali, West Yunnan, where porphyry copper deposits occur, and copper orebodies are controlled by fault or contact zone structures between porphyry massifs and country rocks. Based on detailed field investigation and deep-going analysis, the authors systematically studied the tectonogeochemical features of this mining district, proposed the principle and foundation of metallogenic prognosis, and delineated the most potential mineralization target area.
