复方藏红花油治疗跌打损伤(急性软组织损伤)Ⅲ期临床试验总结

目的:评价复方藏红花油治疗跌打损伤(急性软组织损伤)的临床疗效、安全性。方法:采用多中心、单盲随机平行对照方法,将40 0例跌打损伤(急性软组织损伤)患者分为复方藏红花油组(试验组) 3 0 0例,正红花油组(对照组) 1 0 0例,对比分析两组的临床疗效。结果:1试验组总有效率96%,对照组总有效率82 .0 0 %,试验组疗效优于对照组(P<0 .0 1 )。2两组治疗单项症状均有效。3试验组治疗中医证候有效,且优于对照组。4试验组在治疗过程中未见明显不良反应。结论:复方藏红花油是一种治疗跌打损伤(急性软组织损伤)安全、有效的药物。

老年人烧伤临床特点分析及治疗

目的探讨观察老年人烧伤临床特点及治疗效果。方法将该院52例低热烧伤的老年患者随机分为两组,分别是对照组与观察组,每组26例。对照组采用莫匹罗星软膏进行治疗,观察组采用哌酸软膏进行治疗。结果对照组总有效率76.92%,烧伤创面愈合时间为(18.3±5.1)d;观察组总有效率96.15%,烧伤创面愈合时间为(11.8±3.6)d,两组临床效果相比差异有统计学意义(P<0.01)。结论老年患者的烧伤应因其较高的重视,做到及时发现尽早处理,藏红花油精联合湿润烧伤膏治疗老年烧伤具有更好的疗效,值得临床广泛应用。

Analysis of volatile components in saffron from Tibet and Henan by ultrasonic-assisted solvent extraction and GC-MS

To determine the chemical constituents of volatile components in saffron from the Tibet Autonomous Region and the Henan Province of China and to compare the chemical composition difference in the saffron,the total volatile components were extracted by ultrasonic-assisted solvent extraction（USE）,using five different solvents：diethyl ether,ethanol,ethyl acetate, dichloromethane and acetone,analyzed using gas chromatography-mass spectrometry（GC-MS）and compared to the standard MS data,and their relative contents were calculated by area normalization.The results showed both that USE was an efficient and rapid method for the extraction of the volatile components from saffron and that the components extracted from the same sample using different solvents were different.Comparison of the experimental results of saffron from the Tibet Autonomous Region and the Henan Province of China showed that their volatile components were different in their chemical composition and in their relative percentages.USE/GC-MS is a simple,rapid,and effective method for the analysis of volatile oil components in saffron.
