Oral Disodium Cromoglycate Treatment of A topic Dermatitis

Fourteen adults and 10 children with active atopic dermatitis entered this double blind cross-over study of oral disodium cromoglycate (DSCG) (adults 200 mg qid, children 100 mg qid) compared with placebo. Oral DSCG and placebo were given for 6 weeks in random order. According to the investigators' assessments of eczema, significant differences between active and placebo were found after 6 weeks' treatment, DSCG being favoured (P less than 0.05). No differences were detected in the investigators' assessment of lichenization and overall disease. No significant differences between the two treatments were demonstrated in the patients' assessments. Results from food allergic patients were similar to those from non-food allergic patients. Two patients reported possible side effects of arthralgia and urticaria respectively. There were no treatment effects on serum IgE values or any other laboratory data.     

Disodium cromoglycate versus diet in the treatment and prevention of nickel-positive pompholyx

In some cases that have been diagnosed as contact allergy to nickel, there are repeated cutaneous eruptions of pompholyx, even in areas with no direct contact with the metal. The possible alimentary origin of dyshidrotic eczema should be considered when deciding on therapy. We have collected the clinical data for 24 patients with dyshidrotic eczema caused by nickel, to evaluate the benefit of a low-nickel diet versus treatment with oral disodium cromoglycate, comparing both objective and subjective symptoms. A low-nickel diet does not improve these patients but those treated with DSCG reacted better, from both objective and subjective point of view, than either the controls or the patients treated by diet. We next did intestinal permeability tests before therapy and after 15 days of treatment. We found that nickel uptake diminishes simultaneously with the reduction of absorption through the smaller aqueous "pores". This phenomenon was greatest after DSCG. We suggest that DSCG can help selected cases of pompholyx.     

培美曲塞二钠或多西他赛单药二线治疗晚期非小细胞肺癌的疗效和毒性分析

目的 探讨培美曲塞二钠或多西他赛单药二线治疗晚期非小细胞肺癌的疗效和毒性.方法 选择48例经一线化疗失败的晚期NSCLC患者,按照随机数表法将其分为2组.2组分别实施培美曲塞二钠、多西他赛单药治疗,观察治疗后的不良反应、近期及远期疗效.结果 2组患者化疗后的近期疗效以及远期疗效比较,差异不具有统计学意义(P＞0.05);而培美曲塞二钠组患者化疗后的不良反应远低于多西他赛组,差异具有统计学意义(P＜0.05).结论 培美曲塞二钠在保证对NSCLC的临床治疗效果的同时可以降低其不良反应.     

反相高效液相色谱法测定替硝唑氯化钠注射液中乙二胺四乙酸二钠含量

目的建立测定替硝唑氯化钠注射液中乙二胺四乙酸二钠含量的高效液相色谱法。方法色谱柱为AgilentCis柱（150mm×4．6mm,5灿m）,流动相为乙腈一缓冲液（10％四丁基氢氧化铵溶液6mL,加水稀释至200mL,以磷酸调节pH至6．5）-水（20：20：60）,检测波长为254nm流速为1．0mL／min,柱温为30℃,进样量为20txL。结果乙二胺四乙酸二钠进样量在0．1～2．0肛g范围内与峰面积线性关系良好（r=0．9998）,平均回收率为100．37％,RSD为0．78％（n=9）。结论该方法简便、准确、灵敏度高,重复性好,可用于替硝唑氯化钠注射液中乙二胺四乙酸二钠的含量测定。     

培美曲塞二钠联合卡铂与吉西他滨联合卡铂治疗中晚期非小细胞肺癌的临床对比研究
