简介:目的探讨乙型肝炎病毒pre—S1Ag、pre—S2Ag、HBV—DNA、HBV—M的相关性及其临床意义。方法HBV—DNA采用荧光定量PCR法;HBV—M及pre—S1Ag、pre—S2Ag采用ELISA法,检测96例HBV—DNA阳性感染者血清中pre-S1Ag、pre—S2Ag、HBV—M,同时以30例HBV—M全阴性的健康体检者血清作为对照,并对结果进行统计学分析。结果96例HBV—DNA阳性患者中HBsAg、HBeAg、HBcAb阳性检出率为64.6%;HBsAg、HBeAb、HBcAb阳性检出率为20.8%;HBsAg、HBcAb阳性栓出率为14.6%;pre—S1Ag在96例HBV—DNA阳性标本中检出率为70.8%;pre—S2Ag检出率为79.2%;均明显高于HBeAg的阳性率64.6%,30例对照中未检测出pre—S1Ag、pre—S2Ag及HBV—DNA。结论HBeAg、HBV—DNA、pre—S1Ag、pre—S2Ag之间具有一定的关联性。pre—S1Ag和pre—S2Ag均较HBeAg敏感。pre—S1Ag与pre—S2Ag的栓出率差异无显著性,ELISA检测HBV—M、pre—S2Ag及pre—S1Ag只是表型指标,只能提供HBV感染的间接证据。而HBV—DNA的检测是HBV感染与否的直接证据。HBV—M、pre—S1Ag、pre—S2Ag、HBV—DNA的检测各自有其独特的临床意义。应用pre—S1Ag、pre—S2Ag、HBV—DNA及HBV—M进行联合检测,对HBV感染的早期诊断,了解HBV复制、转归及监测疗效和预后有重要的意义。

简介:1例65岁男性患者因感冒口服感冒灵颗粒,每次1袋,每日3次。第2天,患者口唇及双手出现红斑、水疱.且逐渐增多,部分水疱变血疱,延及躯干和四肢,部分红斑呈靶型,痒痛明显,伴有发热,体温最高39℃。实验室检查:血沉58mm·h^-1,免疫球蛋白E(IgE)211.00IU·mL^-1,C反应蛋白(CRP)25.30mg·L^-1,血红蛋白(Hb)108g·L^-1。诊断为“多形红斑型药疹”。立即停用感冒灵颗粒,给予抗过敏、对症及免疫支持治疗。入院后2d,患者病情进展,加用激素并预防使用抗茵药物,6d后病情好转,14d皮疹基本消退,口服激素及复方甘草酸苷胶囊出院。
简介:目的评估A型肉毒毒素治疗Meige’s综合征的疗效。方法对A型肉毒毒素治疗的30例Meige’s综合征患者资料进行回顾性分析。结果30例Meiges’s综合征患者注射A型肉毒毒素后25例完全缓解,5例明显缓解,总有效率100%。起效时间注射当天~第3天。疗效维持平均为5个月。重复治疗有效。局部不良反应轻微、短暂、可逆,无全身不良反应及过敏反应。结论A型肉毒毒素局部注射是治疗Meige’s综合征的一种安全、有效、简便、易行的方法。

简介:1例44岁女性患者因左肺中央型肺癌(腺癌)、多发脑转移、继发癫痫入院。入院后给予卡马西平0.1g,每天3次口服;20%甘露醇,奥美拉唑,地塞米松静脉滴注。20d后患者全身出现散在皮疹、口腔内多发溃疡,经专科会诊初步考虑服用卡马西平引发过敏性药疹。立即停用以上药物,给予依匹斯汀20mg,每天1次;酮替芬1mg,每天2次;哈西奈德液、曲咪新乳膏和炉甘石洗剂,每天3次,外用。3d后,患者症状加重,确诊为重症多形红斑型药疹。在原治疗方案基础上,加用氨曲南1.5g,阿奇霉素0.5g,甲泼尼松龙40mg,每天2次静脉滴注。2周后患者吞咽正常,停用静脉激素,改为口服,一个月后新鲜皮肤长出,口服激素出院。
