目的评估脑苷肌肽注射液治疗脑出血的临床效果及经济性;方法计算机检索Pubmed/medline、Cochrane Library、中国期刊全文数据库、中文期刊全文数据库和万方数据知识服务平台,收集脑苷肌肽注射液治疗脑出血的随机对照试验,对纳入的文献进行质量评价,使用Rev Man 5.3软件对脑苷肌肽注射液临床疗效进行Meta分析,使用成本-效果分析方法对其进行经济性评价。结果共纳入4篇文献,共计431例患者。Meta分析结果显示,脑苷肌肽注射液联合常规治疗的有效率与单纯常规治疗之间差异有统计学意义[RR=1.15,95%CI(1.06,1.25),P<0.001],在常规治疗基础上使用脑苷肌肽注射液能提高脑出血患者的临床有效率。成本-效果分析显示,与单纯常规治疗相比,在常规治疗基础上使用脑苷肌肽注射液平均每人每天需要额外支付302.50元,14 d额外支付4228.70元,ICER为363.29元/%,即有效率增加一个百分比平均每人需要多花363.29元。结论常规治疗基础上使用脑苷肌肽注射液在效果增加的同时,成本也会增加,支付者需基于对相关指标的支付意愿进行决策。
Avidin-liposome complex is a specific chiral selector used to separate the enantiomers of D,L-tryptophan,D,L-phenylthiohydantoin -serine(D,L-PTH-Ser),D,L-phenylthiohydantoin-threonine(D,L-PTH-Thr) and R,S-pioglitazone hydrochloride in capillary electrochromatography(CEC).The avidin is immobilized on the phospholipids coated in the capillary.The liposome used for the phospholipid coating contains l,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(Cap biotinyl)(sodium salt) (Biotinyl-cap-DPPE)(16:0) and different proportions of L-α-phosphatidylserine(PS) in Tris(hydroxymethyl) aminomethane (Tris) buffer at pH 7.4.A good resolution and reproducibility was obtained by coating the capillary with Biotinyl-cap-DPPE/PS (80:20,mol%) followed by immobilization of 1 mg/mL of avidin solution in N-(2-hydroxyethyl) piperazine-N'-(2-ethanesulfonic acid) (HEPES) buffer at pH 7.4.A comparative study of chiral separation efficiency with different capillary coating methods and preconditioning conditions was conducted.Finally,the electrochromatographic method was successfully used to separate enantiomers of pioglitazone hydrochloride.Therefore,coated CEC will be a promising tool for pharmaceutical enantiomers separation in new drug development.
