目的:分析预防性使用小剂量多巴胺在腰硬联合麻醉下高龄老年人髋部骨折中的应用。方法:选取2017年10月—2020年10月本院行髋部骨折术的高龄老年患者92例,按随机数字表法分为试验组(n=46)和对照组(n=46),两组均行腰硬联合麻醉,对照组在患者血压存在波动时予以小剂量多巴胺,试验组在硬腰联合麻醉穿刺后即刻预防性予以小剂量多巴胺。比较两组麻醉效果、麻醉情况、低血压发生情况、并发症发生率。结果:试验组麻醉总优良率(97.83%)较对照组(82.61%)高(P<0.05);试验组麻醉起效时间、麻醉维

目的:建立清热散结制剂的近红外一致性模型,为鉴别不同厂家的产品提供依据。方法:使用MPA型近红外光谱仪(1.5 m光纤探头)、OPUS 5.5软件,对全部批次样品进行了原始光谱扫描,并对其进行矢量归一化及一阶导数等数学处理方法。结果:将平滑点数及一致性指数(CI值)设置为不同数值后,所建模型均能将不同厂家的清热散结制剂快速筛分及鉴别,且各模型经验证均可行。结论:通过对该品种近红外一致性模型的建立,为更好地快筛不同厂家清热散结制剂提供了科学准确的检验检测方法。

目的:建立HPLC法测定妇康宝口服液中阿魏酸含量的方法。方法:色谱柱为phenomenex Luna C18(2)100?魡(250 mm×4.6 mm,5μm)色谱柱,流动相为乙腈-0.1%磷酸水溶液体系梯度洗脱,流速为1.0 ml/min,检测波长为321 nm,柱温为35℃。结果:阿魏酸在1.5890~10.5930μg/ml浓度范围内呈现良好线性(r=1.0000),精密度(RSD为1.7%)和重复性(RSD为1.1%)良好,在24 h内稳定性良好(RSD为1.8%),加样回收率平均值为97.13
目的:建立电感耦合等离子体质谱(ICP-MS)法测定甲基纤维素中8种元素(铅、砷、汞、镉、钒、硒、钴、钼)的含量。方法:甲基纤维素样品经微波消解后,采用电感耦合等离子体质谱同时测定上述8种元素的含量,并进行了方法学考查。结果:3个厂家10批样品的元素含量均符合要求。8种元素在各自的浓度范围内具有良好的线性关系(r均大于0.999),精密度试验的RSD为0.65%~1.8%,平均回收率为93.7%~104.2%。结论:该方法结果准确,灵敏度高,具有良好的重现性,适用于测定甲基纤维素中8种元素的含量。
