简介:【摘要】目的 探讨免疫球蛋白检验在诊断慢性乙型肝炎中的临床价值。方法 用免疫比浊法对血清免疫球蛋白(IgG、IgA、IgM)进行检测。同时测定凝血酶原活动度(PTA)、总氮红素(TBiL)。结果 慢性乙肝、慢性重型乙肝患者的IgG、IgA、IgM水平都有升高,且较正常对照组,差异明显(P<0.05)。慢性乙肝与慢性重型乙肝组在IgG、IgA、IgM水平对比,差异明显(P<0.05)。恶化组的PTA值较好转组低(P<0.05),而IgG、IgA、IgM及TBiL较好转组高(P<0.05)。结论 免疫球蛋白能够将肝细胞受损程度反映出来,检测此指标可以对慢性乙肝患者肝功能损害情况进行评估,且判断其预后,应用价值突出。
简介:【摘要】心脏康复是近年来备受关注,其涉及多个学科结合,需全面干预并针对不同的患者进行个体化治疗,这些也引起国内外学者的探讨与治疗。心脏康复在多年临床实践中表明,中西医结合的道路会互相发挥其优势,弥补其不足,两者相辅相成,由此可见中西医结合的方式会更好的促进心脏康复的发展,使之更细节化,更深入化,更全面化。
简介:【摘要】目的:探讨小切口手术联合可调节负压治疗非哺乳期乳腺炎的疗效。方法:收集非哺乳期乳腺炎104例。根据治疗方法分为联合组和对照组,每组52例。对照组采用传统手术切除治疗,联合组在行小切口手术切除治疗同时,给与可调节负压技术治疗,对比两组切口红肿消退、伤口愈合、换药次数、住院时间的差异及患者对治疗的满意度,并分析两组的临床疗效。结果:联合组总有效率明显高于对照组 (P<0.05),切口红肿消退时间、伤口愈合时间、换药次数、住院时间均较对照组减少(P<0.05),联合组患者对治疗的满意度明显高于对照组(P<0.05)。结论:小切口手术联合调节负压治疗非哺乳期乳腺炎效果优于单纯的手术治疗,促进患者术后康复,值得推广应用。
