目的:研究替加氟温度敏感性脂质体在家兔体内的动力学特点。方法:家兔静注替加氟温度敏感性脂质体,用微波电疗仪对肝脏局部加热至(42±0.1)℃,测定血中药物浓度变化,观察其体内动力学特点。结果:替加氟温度敏感性脂质体肝脏局部加热后,促进了药物在肝脏局部的释放,改变了其动力学特性,提高了替加氟温度敏感性脂质体的靶向性。结论:替加氟温度敏感性脂质体配合肝脏局部加热可提高其靶向性。     

三种市售中/长链脂肪乳注射液理化指标比较

Objective To compale the physical and chemical parameters of three market available medi-an/long chain fat emulsions.Methods The quality properties were determined and compared according to the fat emulsion injection quality standards in the Chinese Pharmacopeia Convention,the United States Pharmacopeia Con-vention,and the National Standard.Results Products A:the pH value was between 8.2-8.3;the particles with a size larger than 1 μm were 1.23%-1.53% and no particles were larger than 5 μm;the mean particle size was 0.246-0.256μm;the acid value was 0.2;the peroxide and methoxyl aniline values were 0 and 0.9-1.4;the he-molysis phosphatide was 0.6-0.9 g/L. The contents of fat,glycerin,and triglycerides were more than 97% of the labeled amounts;the content of phosphorus was 0.46-0.49 g/L. Products B:the pH value was between 8.2;the partocles with a size larger than 1 μm were 0.81%-1.62% and no particles were larger than 5 μm;the mean parti-cle size was 0.239-0.241 μm;the acid value was 0.4-0.5;the peroxide and methoxyl aniline values were 0 and 0.8-1.4;the hemolysis phosphatide was 0.2-0.6 g/L. The contents of fat,glycerin,and triglycerides were more than 94% of the labeled amounts;the content of phosphorus was 0.42 g/L. Products C:the pH value was between 7.7-8.1;the particles with a size larger than 1 μm were 0.42%-0.86% and no particles were larger than 5 μm;the mean particle size was 0.249-0.262 μm;the acid value was 0.3-0.4;the peroxide and methoxyl aniline values were 0 and 1.8-2.9;the hemolysis phosphatide was 0.5-0.8 g/L. The contents of fat,glycerin,and triglycerides were mole than 96% of the labeled amounts;the content of phosphoms was 0.44-0.46 g/L. Conclusion All properties of the median/long chain fat emulsions produced by the three manufacturers met the National Standard.

结肠癌药物治疗的新进展

结肠癌是最常见的恶性肿瘤之一,在西方国家它是癌症引发死亡的“第三大杀手”,在我国发病率也呈逐年增长的趋势[1]。长期以来,药物治疗该病的唯一途径是静脉输注氟尿嘧啶类药物,如5-氟尿嘧啶和亚叶酸(5-Fu/LV)的联合化疗方案,但该治疗方法毒性大,不良反应严重。因此,人们研制了该药的新剂型,如口服的5-Fu,另外还研制了一些新的化疗药物,比传统药物更有效、安全、低毒[2]。本文就最近几年来结肠癌药物治疗的研究进展作一综述。     

华法林联用卡培他滨致严重皮下出血1例报告

1例68岁男性患者因慢性心房颤动长期服用华法林抗凝治疗11年,其国际标准化比值被控制在1.5~2.3间。2个月前患者被诊出罹患直肠癌,术后口服卡培他滨化疗,但在第3个化疗疗程内出现全身皮肤淤斑、左侧背部皮下血肿等症状,国际标准化比值也升高至5.2。经停用华法林、给予维生素K1治疗后,皮肤淤斑和皮下血肿消退。华法林抗凝作用增强可能与卡培他滨抑制细胞色素P450 2C9同功酶的活性有关。     

肿瘤药学门诊及抗肿瘤治疗药物监测的进展

随着新型抗肿瘤药物和治疗方案不断推陈出新,越来越多的患者转向门诊治疗。国外肿瘤药学门诊多年的实践已证明药师可以通过门诊提供药学服务发挥减少或减轻药物不良反应、提高患者用药依从性、解决药物治疗相关问题、提高生活质量等作用。国内目前开设肿瘤药学门诊医院较少,仍处于起步阶段,主要包括医师药师联合门诊、独立专科门诊和药物咨询门诊。收费权和处方权是制约进一步发展的重要因素。治疗药物监测作为重要的用药监测手段已显示出越来越重要的作用,未来可能在肿瘤药学门诊发挥更大作用。
